[0022] The following embodiments further illustrate and supplement the present invention and are not intended to limit the present invention in any way.

[0023] As shown in FIGS. 1 to 15, the interlocking quick release buckle device of the present invention includes a first connecting buckle 10, a second connecting buckle 20, a quick release buckle 30, a first pulling string 40, and a second pulling string 50. Here, the first connecting buckle 10 and the second connecting buckle 20 are respectively used to connect connected objects such as the front sheet 61 and the rear sheet 62 of the bulletproof vest. The quick release buckle 30 is used to operate the unlocking, and the first pulling string 40 and the second pulling string 50 are used to pull the first connecting buckle 10 and the second connecting buckle 20 to unlock. The first pulling string 40 is connected between the first connecting buckle 10 and the quick release buckle 30, and the second pulling string 40 is connected between the second connecting buckle 20 and the quick release buckle 30. When the user operates the quick release buckle 30, the first pulling string 40 and the second pulling string 50 pull the first pulling string 40 and the second pulling string 50 to sequentially unlock, thereby realizing the effect of quick release.

[0024] As shown in FIG. 1, the first connecting buckle 10 and the second connecting buckle 20 are used to be attached at different positions such that the first connecting buckle 10 is attached to the waist of the bulletproof vest and the second connecting buckle 20 is attached to the shoulder of the bulletproof vest. The number of the first connecting buckle 10 and the second connecting buckle 20 can be set as required. The first connecting buckle 10 and the second connecting buckle 20 may be connecting buckles of the same structure or connecting buckles of different structures, and specifically can be set as required. The shape of the first connecting buckle 10 and the second connecting buckle 20 may be the same or different, and specifically can be set as required.

[0025] The first connecting buckle 10 and the second connecting buckle 20 may be magnetic buckles or non-magnetic buckles such as plug-in buckles, and specifically can be set as required.

[0026] Furthermore, as shown in FIGS. 11 to 15, the first connecting buckle 10 includes a first male buckle 101 and a first female buckle 102. The first male button 101 and the first female button 102 may be locked to each other and may be separated from each other.

[0027] The second connecting buckle 20 includes a second male buckle 201 and a second female buckle 202. The second male button 201 and the second female button 202 may be locked to each other and may be separated from each other.

[0028] The first male buckle 101 and the second male buckle may have the same structure or different structures, and specifically can be set as required.

[0029] The first female buckle 102 and the second female buckle 202 may have the same structure or different structures, and specifically can be set as required.

[0030] As shown in FIGS. 2 to 10, a unlocking operation member 31 is provided to make the quick release buckle 30 operable.

[0031] As shown in FIG. 1, the first drawstring 40 is connected between the first connecting buckle 10 and the quick release buckle 30. Specifically, the first drawstring 40 is connected between the first female buckle 102 and the unlocking operation member 31. When the unlocking operation member 31 is operated, the first drawstring 40 is pulled to activate the first connecting buckle 10 to unlock the first connecting buckle 10. The number of the first wires 40 is the same as the number of the first connecting buckles 10. Each first connecting buckle 10 can be interlocked with the quick release buckle 30 by one first drawstring 40.

[0032] As shown in Fig. 1, the second pulling string 50 is connected between the second connecting buckle 20 and the quick release buckle 30. Specifically, the second pulling string 50 is connected between the second buckle 202 and the unlocking operation member 31. When the unlocking operation member 31 is operated, the second pulling string 50 is pulled, activating the second connecting buckle 20 to unlock the second connecting buckle 20. The number of the second pulling strings 50 matches the number of the second connecting buckles 20. Each second connecting buckle 20 can be interlocked with the quick release buckle 30 by one second pulling string 50.

[0033] The first pulling string 40 and the second pulling string 50 can be selected and used from known rope structures such as wire ropes.

[0034] Furthermore, as shown in Figs. 5, 6, 7, 9, and 10, the first pulling string 40 and the second pulling string 50 have a sleeve structure, which includes a sleeve wire 71 located outside and a core wire 72 located inside the sleeve wire 71. The core wire 72 is preferably movable relative to the sleeve wire 71. It is the core wire 72 that is connected to the unlocking operation member 31 among the first pulling string 40 and the second pulling string 50. When the unlocking operation member 31 is operated, the core wire 72 is pulled and moves relative to the sleeve wire 71 that fixes it.

[0035] In the interlocking quick release buckle device of the present invention, when the unlocking operation member 31 is operated, the first pulling string 40 and the second pulling string 50 are simultaneously pulled, but the degrees of being pulled of the first pulling string 40 and the second pulling string 50 are different, whereby the first connecting buckle 10 and the second connecting buckle 20 are operated to be sequentially unlocked. The first connecting buckle 10 is unlocked first. After the first connecting buckle 101 and the second connecting buckle 202 are separated, the second connecting buckle 20 is unlocked to separate the second connecting buckle 201 and the second connecting buckle 202.

[0036] Furthermore, in some embodiments, as shown in FIGS. 2 to 4, the unlocking operation member 31 includes a first unlocking operation member 311 and a second unlocking operation member 312 that can be oppositely pressed. The first unlocking operation member 311 and the second unlocking operation member 312 are movably provided on the quick release buckle 30. Here, the first unlocking operation member 311 is connected to one end of the first pulling string 40, and the second unlocking operation member 312 is connected to one end of the second pulling string 50. When the first unlocking operation member 311 and the second unlocking operation member 312 are oppositely pressed, the first pulling string 40 and the second pulling string 50 are pulled, and the first connecting buckle 10 and the second connecting buckle 20 are sequentially unlocked.

[0037] Furthermore, as shown in FIGS. 2 to 4, a first elastic member 33 is provided between the first unlocking operation member 311 and the quick release buckle 30, and a second elastic member 34 is provided between the second unlocking operation member 312 and the quick release buckle 30 so that the first connecting buckle 10 and the second connecting buckle 20 are sequentially unlocked when the unlocking operation member 31 is operated. Moreover, the damping coefficient of the first elastic member 33 is smaller than that of the second elastic member 34. In this way, when the first unlocking operation member 311 and the second unlocking operation member 312 are oppositely pressed, in the same situation, the moving stroke of the first unlocking operation member 311 is larger than that of the second unlocking operation member 312, the stroke of the first pulling string 40 being pulled is larger than the stroke of the second pulling string 50 being pulled, and furthermore, the degree of movement of the members for unlocking in the first connecting buckle 10 is larger than the degree of movement of the members for unlocking in the second connecting buckle 20, and furthermore, the first connecting buckle 10 is unlocked earlier than the second connecting buckle 20, realizing that the first connecting buckle 10 and the second connecting buckle 20 are sequentially unlocked.

[0038] In addition, the first elastic member 33 and the second elastic member 34 are also used for the return of the first unlocking operation member 311 and the second unlocking operation member 312. When the first unlocking operation member 311 and the second unlocking operation member 312 are pressed against each other, the first elastic member 33 and the second elastic member 34 are compressed. When the first unlocking operation member 311 and the second unlocking operation member 312 are released, the first elastic member 33 and the second elastic member 34 can return the first unlocking operation member 311 and the second unlocking operation member 312 so as to return to their original states.

[0039] Furthermore, as shown in FIGS. 2 to 4, in order to easily arrange the first elastic member 33 and the second elastic member 34, the quick release buckle 30 may include a fitted case 35 and a base 36, and a spacer portion 361 may be provided in the case 35 and / or the base 36. The first unlocking operation member 311 and the second unlocking operation member 312 are arranged on both sides of the spacer portion (361), and the first unlocking operation member 311 and the second unlocking operation member 312 are spaced from the spacer portion 361 respectively. The first elastic member 33 is connected between the first unlocking operation member 311 and the spacer portion 361, and the second elastic member 34 is connected between the second unlocking operation member 312 and the spacer portion 361.

[0040] Furthermore, as shown in FIGS. 2 to 4, the first unlocking operation member 311 and the second unlocking operation member 312 each include one pressing portion 313 and two connecting portions 314. The connecting portions 314 are arranged on both sides of the pressing portion 313. The pressing portion 313 and the connecting portion 314 may be integrally formed or fixedly connected. In the present invention, it is preferably integrally formed. The pressing portion 313 is for the user to press to unlock. The connecting portion 314 is for connecting the first pulling string 40 / the second pulling string 50. Here, the connecting portion 314 of the first unlocking operation member 311 is connected to the first connecting buckle 10 by the first pulling string 40, and the connecting portion 314 of the second unlocking operation member 312 is connected to the second connecting buckle 20 by the second pulling string 50.

[0041] When a plurality of first connecting buckles 10 and a plurality of second connecting buckles 20 are provided, when the pressing portions 313 of the first unlocking operation member 311 and the second unlocking operation member 312 are pressed against each other, all of the first connecting buckles 10 can be unlocked in unison, and then all of the second connecting buckles 20 can be unlocked in unison.

[0042] 4, the pressing portion 313 is provided with a first pressing region 3131, a second pressing region 3132, and a third pressing region 3133. The first pressing region 3131 and the third pressing region 3133 are located on both sides of the second pressing region 3132.

[0043] When the first pressing area 3131 of the first unlocking operation member 311 and the second unlocking operation member 312 are pressed against each other, one of the first connecting buckles 10 is interlocked and unlocked, and then one of the second connecting buckles 20 is interlocked and unlocked. For example, after the first connecting buckle 10 on the left hip of the bulletproof vest is interlocked and unlocked, the second connecting buckle 20 on the left shoulder can be interlocked and unlocked.

[0044] When the third pressing area 3133 of the first unlocking operation member 311 and the second unlocking operation member 312 are pressed against each other, the other first connecting buckles 10 are interlocked and unlocked, and then the other second connecting buckles 20 are interlocked and unlocked. For example, after the first connecting buckle 10 on the right hip of the bulletproof vest is interlocked and unlocked, the second connecting buckle 20 on the right shoulder can be interlocked and unlocked.

[0045] When the first unlocking operation member 311 and the second pressing area 3132 of the second unlocking operation member 312 are pressed in opposition to each other, all of the first connecting buckles 10 are unlocked in conjunction with each other, and then all of the second connecting buckles 20 are unlocked in conjunction with each other. In other words, after the first connecting buckles 10 on both sides of the waist are unlocked in conjunction with each other, the second connecting buckles 20 on the left and right shoulders can be unlocked in conjunction with each other.

[0046] When a first pressing region 3131, a second pressing region 3132, and a third pressing region 3133 are provided in the pressing portion 313, the first elastic member 33 and the second elastic member 34 are provided between the connecting portion 314 and the spacer portion 361, so that when the first pressing region 3131, the second pressing region 3132, and the third pressing region 3133 are pressed, it is guaranteed that they are interlocked with the first pulling string 40 / the second pulling string 50. Specifically, one end of the first elastic member 33 abuts against the connecting portion 314 of the first unlocking operation member 311, and the other end abuts against the spacer portion 361. One end of the second elastic member 34 abuts against the connecting portion 314 of the second unlocking operation member 312, and the other end abuts against the spacer portion 361.

[0047] In some embodiments, as shown in FIGS. 5 to 10, the unlocking operation member 31 is rotatable about a fixed rotation center. The unlocking operation member 31 is provided with a first guide surface 315 and a second guide surface 316. The first guide surface 315 and the second guide surface 316 have different guide strokes for making the first pulling string 40 and the second pulling string 50 have different strokes. The first pulling string 40 is connected to the unlocking operation member 31 and is connected to the first connecting buckle 10 by the first guide surface 315. The second pulling string 50 is connected to the unlocking operation member 31 and is connected to the second connecting buckle 20 by the second guide surface 316. When the unlocking operation member 31 is operated to rotate about the rotation center, the first pulling string 40 and the second pulling string 50 move along the first guide surface 315 and the second guide surface 316 respectively. Since the guide strokes of the first guide surface 315 and the second guide surface 316 are different, during the rotation of the unlocking operation member 31, the moving strokes of the first pulling string 40 and the second pulling string 50 are also different, and the first connecting buckle 10 and the second connecting buckle 20 can be interlocked to sequentially unlock.

[0048] Furthermore, as shown in FIGS. 5 to 10, the curvature of the first guide surface 315 is greater than the curvature of the second guide surface 316. Thereby, when operating the rotation of the unlocking operation member 31, the degree to which the first pulling string 40 is pulled is greater than the degree to which the second pulling string 50 is pulled, and the first connecting buckle 10 connected to the first pulling string 40 is unlocked before the second connecting buckle 20 connected to the second pulling string 50, and sequential unlocking of the first connecting buckle 10 and the second connecting buckle 20 can be realized.

[0049] Furthermore, as shown in FIGS. 5 to 10, the first guide surface 315 may be provided on a curved surface, and the second guide surface 316 may be provided on a flat surface. The first guide surface is raised with respect to the second guide surface 316, whereby sequential unlocking of the first connecting buckle 10 and the second connecting buckle 20 can be realized.

[0050] Furthermore, as shown in FIGS. 5 to 10, the unlocking operation member 31 is provided with a first pulling string hole 317 and a second pulling string hole 318. The first pulling string hole 317 is connected to the first guide surface 315, and the second pulling string hole 318 is connected to the second guide surface 316. One end of the first pulling string 40 is restricted within the first string pulling hole 317, and the other end is connected to the first connecting buckle 10 via the first guide surface 315. One end of the second pulling string 50 is restricted within the second pulling string hole 318, and the other end is connected to the second connecting buckle 20 via the second guide surface 316. Thus, when the unlocking operation member 31 rotates, along with the rotation of the unlocking operation member 31, the first pulling string 40 and the second pulling string 50 move via the first guide surface 315 and the second guide surface 316.

[0051] Furthermore, as shown in FIGS. 5 to 10, the first string pulling hole 317 and the second string pulling hole 318 are located at the same end of the first guide surface 315 and the second guide surface 316, and the first pulling string 40 and the second pulling string 50 are pulled out from the same end of the unlocking operation member 31 and are respectively connected to the first connecting buckle 10 and the second connecting buckle 20. Thereby, the arrangement of the pulling strings is made more beautiful, which is advantageous for sewing and fixing the pulling strings.

[0052] Furthermore, the number of the unlocking operation members 31 can be set as required. As shown in FIG. 6, the unlocking operation member 31 can be provided, and as shown in FIG. 9, a plurality of unlocking operation members 31 can be provided. When a plurality of unlocking operation members 31 are provided, the first guide surface 315 and the second guide surface 316 are provided on each unlocking operation member 31.

[0053] Furthermore, as shown in FIGS. 5 to 10, in order to rotate the unlocking operation member 31 around the fixed rotation center, the unlocking operation member 31 is rotatably connected to the housing. The housing includes a case 35 and a buckle holder 37 which are fitted and connected. An installation space for installing the unlocking operation member 31 is formed between the case 35 and the buckle holder 37. The case 35 is provided with a see-through hole 351 through which the unlocking operation member 31 can move, and the buckle holder 37 is provided with a connecting ear portion 371 facing the see-through hole 351. Regardless of the shape of the connecting ear portion 371, a second rotation shaft hole 372 into which a rotation shaft 38 is inserted is provided. Both ends of the rotation shaft 38 may be inserted into the buckle holder 37 or may be inserted into the case 35. Specifically, they can be provided as required. Preferably, both ends of the rotation shaft 38 are inserted into the case 35. The unlocking operation member 31 is provided with a first rotation shaft hole 319 which is fitted on the rotation shaft 38 and is located in the see-through hole 351. The unlocking operation member 31 is rotatable around the rotation shaft 38. The rotation shaft 38 forms the rotation center of the unlocking operation member 31.

[0054] As shown in FIGS. 5 to 10, in order to rotate and return the unlocking operation member 31, a return torsion spring 39 is provided between the unlocking operation member 31 and the rotating shaft 38. The return torsion spring 39 is fitted on the rotating shaft 38, and the torsion arm 391 of the return torsion spring 39 is connected to the unlocking operation member 31 and / or the housing and / or the buckle holder 37. In the default state, the unlocking operation member 31 is in close contact with the buckle holder 37. When unlocking is required, the unlocking operation member 31 is pulled outward in a direction away from the buckle holder 37, and the unlocking operation member 31 is rotated, so that the first pulling string 40 and the second pulling string 50 can be pulled to different extents. When the unlocking operation member 31 rotates outward, the torsion arm 391 of the return torsion spring 39 is in a state of receiving force. When the unlocking operation member 31 is released, the torsion arm 391 of the return torsion spring 39 returns and moves the unlocking operation member 31 in a direction approaching the buckle holder 37, realizing the automatic return of the unlocking operation member 31.

[0055] As shown in FIGS. 11 to 15, the first male buckle 101 and the second male buckle 201 may have the same structure or different structures, and specifically can be set as required. The first female buckle 102 and the second female buckle 202 may have the same structure or different structures, and specifically can be set as required.

[0056] In the present application, as shown in FIGS. 11 to 15, the first male buckle 101 and the second male buckle 201 are each provided with a locking tongue 81, and the first female button 102 and the second female button 202 are provided with a locking hole 921 into which the locking tongue 81 can be inserted and a locking member 93 movably provided. The locking member 93 can engage with the locking tongue 81 so that the first male buckle 101 is locked and connected to the first female buckle 102 and the second male buckle 201 is locked and connected to the second female buckle 202.

[0057] Each of the locking members 93 is connected to the corresponding first pulling string 40 or second pulling string 50, whereby the connection between the first male buckle 101 and the first female buckle 102, and the second male buckle 201 and the second female buckle 202 can be released from the locked connection by pulling out the corresponding first pulling string 40 and second pulling string 50 to disengage the engagement with the locking tongue 81.

[0058] In some embodiments, as shown in FIGS. 10 to 13, the locking member 93 includes a locking portion 931, an operating portion 932, and a scraping portion 933 that are integrally formed or fixedly connected. The locking portion 931, the operating portion 932, and the scraping portion 933 are relatively immovable with respect to each other. The locking portion 931 faces the scraping portion 933 with a space therebetween. Here, the locking portion 931 is used to engage with the locking tongue 81 to hold the male buckle structure 80 in the female locking structure 90. The scraping portion 933 is used to move the locking tongue 81 out of the locking hole 921. The operating portion 932 is connected to the corresponding first pulling string 40 and second pulling string 50, and moves the locking portion 931 and the scraping portion 933 when the first pulling string 40 and the second pulling string 50 are pulled out. When the unlocking operation member 31 is operated, the first pulling string 40 and the second pulling string 50 pull the operating portion 932, thereby moving the locking portion 931 and the scraping portion 933. The movement of the locking portion 931 disengages the locking portion 931 from the locking tongue 81, and the movement of the scraping portion 933 moves the locking tongue 81 out of the locking hole 921.

[0059] In some embodiments, as shown in FIGS. 14 and 15, the locking member includes a relatively movable locking portion 931, an operating portion 932, and a scraping portion 933. The scraping portion 933 is movably provided on the operating portion 932, and a third elastic member 934 is provided between the scraping portion 933 and the operating portion 932. The locking portion 931 faces the scraping portion 933 with a space therebetween. Here, the locking portion 931 is used to engage with the lock tongue 81 to hold the male buckle structure 80 in the female lock structure 90. The scraping portion 933 is used to move the lock tongue 81 out of the lock hole 921. The operating portion 932 is connected to the corresponding first pulling string 40 and second pulling string 50, and moves the locking portion 931 and the scraping portion 933 under the pulling of the first pulling string 40 and the second pulling string 50. When the unlocking operation member 31 is operated, the first pulling string 40 and the second pulling string 50 pull the operating portion 932, so that the scraping portion 933 is moved between the lock tongue 81 and the portion where the lock tongue 81 is coupled to the first female buckle 102 / second female buckle 202, and the lock tongue 81 tends to move out of the lock hole 921. At this time, the scraping portion 933 only acts on the lock tongue 81, and since the lock tongue 81 is still engaged with the locking portion 931 at this time, the scraping portion 933 cannot directly move the lock tongue 81 out of the lock hole 921. Under the pulling of the corresponding first pulling string 40 / second pulling string 50, the operating portion 932 moves so as to be able to operate the operating portion 931, releases the engagement between the locking portion 931 and the lock tongue 81, and the scraping portion 933 moves the lock tongue 81 out of the lock hole 921.

[0060] Furthermore, as shown in FIGS. 10 to 15, a second magnet member 82 is provided in the lock tongue 81, a first magnet member 94 is provided at a position facing the lock hole 921 in the first female buckle 102 and the second female buckle 202, and a third magnet member 95 is provided at the locking portion 931. The second magnet member 82 can attract the first magnet member 94 so as to be inserted into the lock hole. When the lock tongue 81 is inserted into the lock hole 921, the second magnet member can attract or repel the third magnet member 95 so as to activate the locking portion 931 and engage the locking portion 931 with the lock tongue 81. After the lock tongue 81 exits the lock hole 921, the first magnet member 94 can attract or repel the third magnet member 95 so as to hold the locking portion 931 outside the range of the lock hole 921.

[0061] Furthermore, as shown in FIGS. 10 to 15, a magnet holder 922 is provided in the lock hole 921, the first magnet member 94 is provided on the magnet holder 922, and a first side opening 9222 and a second side opening 9223 penetrating the lock hole 921 are provided on the side of the magnet holder 922. A socket 811 into which the locking portion 931 can be inserted is provided on the lock tongue 81. The locking portion 931 can be inserted into the socket 811 through the first side opening 9222, and the scraping portion 933 can be inserted between the end of the lock tongue 81 and the magnet holder 922 through the second side opening 9223.

[0062] Thereby, the interlocking quick release buckle device of the present invention is formed. By operating the quick release buckle 30, it is realized that the first connecting buckle 10 and the second connecting buckle 20 are sequentially unlocked, and the effect of unlocking a plurality of connecting buckles with one button is realized, which is convenient for the user to use.

[0063] In order to more specifically introduce the configuration of the interlocking quick release buckle device of the present invention, the following specific embodiments will be used for description.

[0064] Embodiment 1 As shown in FIGS. 2 and 3, the quick release buckle 30 of the present embodiment includes a case 35, a base 36, a first unlocking operation member 311, a second unlocking operation member 312, a first elastic member 33, and a second elastic member 34.

[0065] As shown in FIGS. 2 and 3, the case 35 and the base 36 are fitted and connected, and the base 36 is used to be fixed to an item such as a bulletproof vest. The shapes of the case 35 and the base 36 are not limited. A fitting space is formed between the case 35 and the base 36 for fitting and attaching the first unlocking operation member 311, the second unlocking operation member 312, the first elastic member 33, and the second elastic member 34.

[0066] As shown in FIGS. 2 and 3, a spacer portion 361 is provided in the base 36 and / or the case 35. In the present embodiment, the spacer portion 361 is provided at the central position of the base 36. The spacer portion 361 is integrally formed with the base 36 and protrudes from the surface of the base 36.

[0067] As shown in FIGS. 2 and 3, the first unlocking operation member 311 and the second unlocking operation member 312 are movably provided between the case 35 and the base 36, and the first unlocking operation member 311 and the second unlocking operation member 312 are arranged on both sides of the spacer portion 361. The first unlocking operation member 311 and the second unlocking operation member 312 each include one pressing portion 313 and two connecting portions 314. The connecting portion 314 is formed by the end portion of the pressing portion 313 extending to both sides of the pressing portion 313, and the pressing portion 313 and the connecting portion 314 form a shape similar to T. The pressing portion 313 is used for pressing and is partially or entirely located outside the case 35 and the chassis 36. The connecting portion 314 is located between the case 35 and the base 36. In order to connect the first pulling string 40 and the second pulling string 50, string pulling holes for pulling wire ropes are respectively provided in the connecting portion 314. The two connecting portions 314 of the first unlocking operation member 311 can be connected to two first pulling strings 40 through the respective string pulling holes. The two connecting portions 314 of the second unlocking operation member 312 can be connected to two second pulling strings 50 through the respective string pulling holes.

[0068] The first elastic member 33 and the second elastic member 34 are movably provided between the case 35 and the base 36. Here, one end of the first elastic member 33 abuts against the pressing portion 313 or the connecting portion 314 of the first unlocking operation member 311, and the other end abuts against the spacer portion 361. One end of the second elastic member 34 abuts against the pressing portion 313 or the connecting portion 314 of the second unlocking operation member 312, and the other end abuts against the spacer portion 361. In this embodiment, the first elastic member 33 and the second elastic member 34 are selected and used as springs, and the damping coefficient of the first elastic member 33 is smaller than the resistance coefficient of the second elastic member 34. With the same pressing force, the compression degree of the first elastic member 33 is larger than the compression degree of the second elastic member 34. In the default state, the first elastic member 33 and the second elastic member 34 are in a compressed state or a natural state. When the first unlocking operation member 311 and the second unlocking operation member 312 of the quick release buckle 30 are pressed against each other, the first elastic member 33 and the second elastic member 34 are compressed, and the compression amount of the first elastic member 33 is larger than the compression amount of the second elastic member 34.

[0069] In this embodiment, when the first unlocking operation member 311 and the second unlocking operation member 312 of the quick release buckle 30 are pressed against each other, the two first connecting buckles 10 are unlocked first, and then the two second connecting buckles 20 are unlocked. That is, by being pressed against each other, the two connecting buckles can be unlocked simultaneously and interlocked.

[0070] Embodiment 2 As shown in FIG. 4, the quick release buckle 30 of this embodiment includes a case 35, a base 36, a first unlocking operation member 311, a second unlocking operation member 312, a first elastic member 33, and a second elastic member 34.

[0071] As shown in Fig. 4, the case 35 and the base 36 are fitted and connected, and the base 36 is used to be fixed to an item such as a bulletproof vest. The shapes of the case 35 and the base 36 are not limited. A fitting space is formed between the case 35 and the base 36 for fitting and for attaching the first unlocking operation member 311, the second unlocking operation member 312, the first elastic member 33, and the second elastic member 34.

[0072] As shown in Fig. 4, a spacer portion 361 is provided in the base 36 and / or the case 35. In this embodiment, the spacer portion 361 is provided at the central position of the base 36. The spacer portion 361 is integrally formed with the base 36 and protrudes from the surface of the base 36.

[0073] As shown in Fig. 4, the first unlocking operation member 311 and the second unlocking operation member 312 are movably provided between the case 35 and the base 36, and the first unlocking operation member 311 and the second unlocking operation member 312 are arranged on both sides of the spacer portion 361. The first unlocking operation member 311 and the second unlocking operation member 312 each include one pressing portion 313 and two connecting portions 314.

[0074] As shown in Fig. 4, the connecting portion 314 is formed by the end of the pressing portion 313 extending to both sides of the pressing portion 313, and the pressing portion 313 and the connecting portion 314 form a shape similar to T, and the connecting portion 314 is located between the case 35 and the base 36.

[0075] The pressing portion 313 is used for pressing and is partially or entirely located outside the case 35 and the chassis 36.

[0076] In order to facilitate the connection of the first pulling string 40 and the second pulling string 50, string pulling holes for pulling a wire rope are respectively provided in the connecting portions 314. The two connecting portions 314 of the first unlocking operation member 311 can be respectively connected to the two first pulling strings 40 through the string pulling holes. The two connecting portions 314 of the second unlocking operation member 312 can be respectively connected to the two second pulling strings 50 through the string pulling holes.

[0077] As shown in FIG. 4, a first pressing region 3131, a second pressing region 3132, and a third pressing region 3133 are further provided in the pressing portion 313.

[0078] As shown in FIG. 4, the first pressing region 3131 and the third pressing region 3133 are arranged on both sides of the second pressing region 3132. Preferably, the first pressing region 3131 and the third pressing region 3133 are symmetric with respect to the second pressing region 3132, and the second pressing region 3132 is located at the central position of the pressing portion 313.

[0079] In order to be convenient for the user to use, marks corresponding to the corresponding positions of the first pressing region 3131, the second pressing region 3132, and the third pressing region 3133 can be provided. The marker can be marked with a character marker, a pattern marker, or a shape, such as setting the first pressing region 3131, the second pressing region 3132, and the third pressing region 3133 to a slightly concave shape.

[0080] The first elastic member 33 and the second elastic member 34 are movably provided between the case 35 and the base 36. Here, two first elastic members 33 are provided, one end of each abuts against the connecting portion 314 of the first unlocking operation member 311, and the other end of each abuts against the spacer portion 361. Two second elastic members 34 are provided, one end of each abuts against the connecting portion 314 of the second unlocking operation member 312, and the other end of each abuts against the spacer portion 361.

[0081] In this embodiment, the first elastic member 33 and the second elastic member 34 are selected and used as springs, and the damping coefficient of the first elastic member 33 is smaller than the resistance coefficient of the second elastic member 34. Under the same pressing force, the compression degree of the first elastic member 33 is greater than that of the second elastic member 34. In the default state, the first elastic member 33 and the second elastic member 34 are in a compressed state or a natural state. When the first unlocking operation member 311 and the second unlocking operation member 312 are pressed against each other, the first elastic member 33 and the second elastic member 34 are compressed, and the compression amount of the first elastic member 33 is greater than that of the second elastic member 34.

[0082] When the second pressing region 3132 of the pressing portion 313 of the first unlocking operation member 311 and the second unlocking operation member 312 are pressed against each other, the entire first unlocking operation member 311 moves in the direction of the spacer portion 361 so that the displacement amounts of the two first pulling strings 40 are the same or approximately the same, and the corresponding two first connecting buckles 10 are unlocked in conjunction. Similarly, the entire second unlocking operation member 312 also moves in the direction of the spacer portion 361 so that the displacement amounts of the two second pulling strings 50 are the same or approximately the same, and the corresponding two second links 20 are unlocked in conjunction. Since the damping coefficient of the first elastic member 33 is smaller than that of the second elastic member 34, the two first connecting buckles 10 are unlocked earlier than the two second connecting buckles 20, realizing the effect that the first connecting buckles 10 and the second connecting buckles 20 are sequentially unlocked.

[0083] When the first pressing regions 3131 of the pressing portions 313 of the first unlocking operation member 311 and the second unlocking operation member 312 are pressed against each other, the connecting portion 314 close to the first pressing portion 3131 moves in the direction of the spacer portion 361 by a sufficient distance to interlock the corresponding first pulling string 40 / second pulling string 50 to cause sufficient displacement to unlock the first connecting buckle 10 and the second connecting buckle 20. The connecting portion 314 away from the first pressing portion 3131 either does not move or cannot generate sufficient displacement, so the first connecting buckle 10 and the second connecting buckle 20 are interlocked to be unlocked. Therefore, when the first pressing regions 3131 of the first unlocking operation member 311 and the second unlocking operation member 312 are pressed against each other, one of the first connecting buckles 10 can be unlocked, and one of the second connecting buckles 20 can be sequentially unlocked in an interlocking manner.

[0084] Similarly, when the third pressing regions 3133 of the pressing portions 313 of the first unlocking operation member 311 and the second unlocking operation member 31 are pressed against each other, the connecting portion 314 adjacent to the third pressing portion 3133 moves in the direction of the spacer portion 361 by a sufficient distance to interlock the corresponding first pulling string 40 / second pulling string 50 to cause sufficient displacement to unlock the first connecting buckle 10 and the second connecting buckle 20. The connecting portion 314 away from the third pressing region 3133 either does not move or cannot generate sufficient displacement, so the first connecting buckle 10 and the second connecting buckle 20 are interlocked to be unlocked. Therefore, when the third pressing regions 3131 of the first unlocking operation member 311 and the second unlocking operation member 312 are pressed against each other, the other first connecting buckles 10 and the other second connecting buckles 20 can be sequentially unlocked in an interlocking manner.

[0085] The interlocking quick release buckle device of this embodiment can not only interlock and sequentially unlock all the first connecting buckles 10 and the second connecting buckles 20 by pressing the second pressing region 3132 against each other, but also interlock and sequentially unlock a single first connecting buckle 10 and a second connecting buckle 20 by pressing the first pressing region 3131 and the second pressing region 3132 against each other, which can meet the usage needs in specific scenes.

The first string pulling hole 317 and the second string pulling hole 318 can preferably be provided as through holes to facilitate string pulling.

[0089] As shown in FIGS. 5 to 8, the number of the first string pulling holes 317 is the same as the number of the first pulling strings 40. In this embodiment, one first string pulling hole 317 is provided. The number of the second string pulling holes 318 is the same as the number of the second pulling strings 50. In this embodiment, one second string pulling hole 318 is provided.

[0090] The shapes of the first string pulling hole 317 and the second string pulling hole 318 are not limited. The ends of the first pulling string 40 and the second pulling string 50 may be restricted to connect the first pulling string 40 and the second pulling string 50 to the lock release operation member 31.

[0095] Furthermore, in order to facilitate the operation by the user, a string pulling hole can also be provided at one end of the unlocking operation member 31 away from the first rotation shaft hole 319, whereby a drawstring can be provided, and thus, the user can rotate the unlocking operation member 31 by pulling the string.

[0096] Furthermore, in order to maintain the aesthetic appearance and facilitate the installation of the first pulling string 40 and the second pulling string 50, a cover groove 3112 is provided on the side of the unlocking operation member 31 away from the first guide surface 315 and the second guide surface 316. The cover groove 3112 penetrates through the first pulling string hole 317 and the second pulling string hole 318. A removable cover 3113 is attached in the cover groove 3112. The cover 3113 can close one end of the first string pulling hole 317 and the second string pulling hole 318.

[0097] As shown in FIGS. 5 to 8, the housing includes a case 35 and a buckle holder 37 that are fitted and connected. The fitting connection between the case 35 and the buckle holder 37 can be positioned and connected by positioning posts without the need to fasten them together. In this embodiment, several protruding positioning posts are provided on the side of the case 35 facing the buckle holder 37, and several positioning holes are provided on the side of the buckle holder 37 facing the case 35. The positioning posts can be inserted into the positioning holes to enable the fitting connection between the case 35 and the buckle holder 37. At this time, the case 35 and the buckle holder 37 are not tightened, and they can be easily detached and attached.

[0098] As shown in FIGS. 5 to 8, the case 35 is provided with a large-area see-through hole 351 for operating the unlocking operation member 31, and the area of the see-through hole 351 is adapted to the shape of the unlocking operation member 31.

[0099] As shown in FIGS. 5 to 8, in order to facilitate the rotational connection of the unlocking operation member 31, the buckle holder 37 is provided with a connecting ear portion 371. The connecting ear portion 371 protrudes toward the see-through hole 351 of the case 35. The number of the connecting ear portions 371 can be set as required. The connecting ear portion 371 is provided with a second rotation shaft hole 372.

[0100] As shown in FIGS. 5 to 8, the rotating shaft 38 is inserted into the second rotating shaft hole 372 of the connecting ear portion 371, and both ends of the rotating shaft 38 overlap the case 35.

[0101] As shown in FIGS. 5 to 8, the unlocking operation member 31 is rotationally connected to the rotating shaft 38 by its first rotating shaft hole 319 and is rotatable about the rotating shaft 38. The position where the central axis of the rotating shaft 38 is located forms the rotation center of the unlocking operation member 31.

[0102] As shown in FIGS. 5 to 8, when the unlocking operation member 31 is rotationally connected to the rotating shaft 38, the first guide surface 315 and the second guide surface 316 in the unlocking operation member 31 face the buckle holder 37, and the unlocking operation member 31 is rotatable in a direction away from the buckle holder 37.

[0103] As shown in FIGS. 5 to 8, the return torsion spring 39 is fitted on the rotating shaft 38 and is located in the torsion spring groove 3110. The torsion arm 391 of the return torsion spring 39 is located in the locking groove 3111. When the unlocking operation member 31 rotates in a direction away from the buckle holder 37, the torsion arm 391 of the return torsion spring 39 is twisted and receives a force. When the external force is lost, the torsion arm 391 returns, rotating the unlocking operation member 31 in the direction of the buckle holder 37 to return.

[0104] As shown in FIGS. 5 to 8, in order to easily pull out the first pulling string 40 and the second pulling string 50, a third pulling string hole 310 and a fourth pulling string hole 320 are provided at the bottom of the housing. The third string pulling hole 310 is located at one end facing the first string pulling hole 317 of the first guide surface 315, and the fourth string pulling hole 320 is located at one end facing the second string pulling hole 318 of the second guide surface 316. The third string pulling hole 310 and the fourth string pulling hole 320 penetrate through the inside and outside of the housing.

[0105] As shown in FIGS. 5 to 8, both the first pulling string 40 and the second pulling string 50 have a sleeve structure. Here, the end of the core wire 72 of the first pulling string 40 is provided in the first string pulling hole 317, the end of the sleeve wire 71 of the first pulling string 40 is provided in the third string pulling hole 310, and the core wire 72 portion between the end of the core wire 72 and the end of the sleeve wire 71 of the first pulling string 40 passes through the first guide surface 315. The end of the core wire 72 of the second pulling string 50 is provided in the second wire hole 318, the end of the ferrule wire 71 of the second pulling string 50 is provided in the fourth wire hole 320, and the core wire 72 portion between the end of the core wire 72 and the end of the sleeve wire 71 of the second pulling string 50 passes through the second guide surface 316.

[0106] Thus, when the unlocking operation member 31 is operated to rotate in a direction away from the buckle holder 37, the core wires 72 of the first pulling string 40 and the second pulling string 50 are pulled. Since the strokes of the first guide surface 315 and the second guide surface 316 through which they pass are different, the first connecting buckle 10 and the second connecting buckle 20 linked thereto can be pulled to different extents, and the first connecting buckle 10 and the second connecting buckle 20 can be linked to sequentially unlock.

[0107] The mounting seat 330 is for attaching the quick release buckle 30 to an instrument such as a bulletproof vest. The mounting seat 330 is provided with screw holes for fixing the mounting seat 330 to the place of use.

[0108] As shown in FIGS. 5 to 8, in order to facilitate the connection of the housing, the mounting seat 330 is provided with a receiving groove 3301. One end of the receiving groove 3301 is open to form an insertion port 3302. On both sides of the receiving groove 3301, restricting portions 3303 are provided at intervals from the bottom of the receiving groove 3301. Between the restricting portions 3303, a first opening is formed at intervals from each other. The direction of the first opening coincides with the opening direction of the watermark hole 351 and is perpendicular to the direction of the insertion port 3302.

[0109] The size of the shape of the accommodation groove 3301 is adapted to the size of the shape of the housing. The housing can be inserted into the accommodation groove 3301 along the insertion port 3302 and is restricted by the restricting portion 3303, so that the housing is restricted in the accommodation groove 3301. Since there is no fastening between the case 35 of the housing and the buckle holder 37, when the housing is accommodated in the accommodation groove 3301, the restricting portion 3303 can also prevent the case 35 and the buckle holder 37 from being pushed and loosened.

[0110] Furthermore, as shown in FIGS. 5 to 8, a passage groove 352 is provided on the surface of the case 35 facing the restricting portion 3303, and a protruding positioning portion 3304 is provided on the restricting portion 3303. The positioning portion 3304 is adapted to the passage groove 352, and its extending direction is consistent with the insertion direction of the housing. When the housing is inserted into the accommodation groove 3301 along the insertion port 3302, the positioning portion 3304 fits into the passage groove 352, enabling the housing to move along a straight line and facilitating smoother movement.

[0111] Furthermore, as shown in FIGS. 5 to 8, an elastic pressing portion 3305 is provided at the bottom of the accommodation groove 3301, that is, at one end facing the insertion port 3302. One end of the elastic pressing portion 3305 is connected to the mounting seat 330, and the other end protrudes to the cantilever end and has elasticity. In this embodiment, by providing a hole between the mounting seat 330 and the elastic pressing portion 3305, one end of the elastic pressing portion 3305 is used as the cantilever end, and the elastic pressing portion 3305 can be elastically pressed. The shape of the elastic pressing portion 3305 is not limited.

[0112] As shown in FIGS. 5 to 8, a positioning protrusion 3306 is provided on the elastic pressing portion 3305. Correspondingly, a buckle hole 373 is provided on the buckle holder 37. When the positioning protrusion 3306 enters the buckle hole 373, the positioning protrusion 3306 can limit the movement of the housing and enable the housing to be assembled together with the mounting seat 330.

[0113] When the housing is inserted into the accommodation groove 3301 along the insertion port 3302, the back of the housing presses the elastic pressing portion 3305 until the housing moves to the buckle hole 373 and corresponds to the positioning protrusion 3306. The positioning protrusion 3306 can engage with the buckle hole 373 to hold the housing in the accommodation groove 3301.

[0114] Furthermore, as shown in FIGS. 5 to 8, a first guide slope 3307 is provided on the positioning protrusion 3306. The first guide slope 3307 faces the direction of the insertion port 3302, one end of which is connected to the bottom of the accommodation groove 3301, and the other end is higher than the bottom of the accommodation groove 3301. Correspondingly, a second guide slope that fits the first guide slope 3307 can be provided in the buckle hole 373. The inclination mode of the second guide slope is consistent with the inclination mode of the first guide slope 3307. When the positioning protrusion 3306 enters the buckle hole 373, the first guide slope 3307 and the second guide slope are attached to each other.

[0115] By providing the first guide slope 3307 and the second guide slope, it is advantageous for the housing to press the elastic pressing portion 3305, while it is advantageous for the housing to escape in the reverse direction from the accommodation groove 3301. When it is necessary to remove the housing from the accommodation groove 3301 of the mounting seat 330, by pressing the elastic pressing portion 3305 to move the positioning protrusion 3306 out of the buckle hole 373, the housing can be moved along the direction of the insertion port 3302 and taken out of the housing accommodation groove 3301.

[0116] As a result, as shown in FIGS. 5 to 8, the quick release buckle 30 of the present embodiment is formed. The unlocking operation member 31 is rotatably connected to the rotation shaft 38. The rotation shaft 38 is attached to the connection ear portion 371 of the buckle holder 37. The buckle holder 37 is fitted and connected to the case 35 and is provided in the accommodation groove 3301 of the mounting seat 330. One end of the first pulling string 40 is connected to the unlocking operation member 31, and the other end is drawn out of the unlocking operation member 31 via the first guide surface 315. One end of the second pulling string 50 is connected to the unlocking operation member 31, and the other end is drawn out of the unlocking operation member 31 via the second guide surface 316. Since the guide strokes of the first guide surface 315 and the second guide surface 316 are different, when the unlocking operation member 31 is rotated in a direction away from the buckle holder 37, the first pulling string 40 and the second pulling string 50 move along the first guide surface 315 and the second guide surface 316, and the connected first connecting buckle 10 and second connecting buckle 20 can be sequentially unlocked. When the external force is relaxed, the unlocking operation member 31 is rotated and returned in the direction of the buckle holder 37 by the return torsion spring 39.

[0117] Embodiment 4 The basic configuration of the quick release buckle 30 of the present embodiment is the same as that of Embodiment 3. As shown in FIGS. 9 and 10, the difference from Embodiment 3 is that the unlocking operation member 31 of the present embodiment is provided with two, including a first unlocking operation member 311 and a second unlocking operation member 312.

[0118] The basic configurations of the first unlocking operation member 311 and the second unlocking operation member 312 are the same as those of the unlocking operation member 31 of the embodiment provided with the first guide surface 315 and the second guide surface 316.

[0119] The first unlocking operation member 311 and the second unlocking operation member 312 are rotationally connected to the rotating shaft 38. In order to facilitate the user to control the first unlocking operation member 311 and the second unlocking operation member 312 simultaneously, the first unlocking operation member 311 is provided with an extension portion extending in the direction of the second unlocking operation member 312 located between the second unlocking operation member 312 and the buckle holder 37. When the first unlocking operation member 311 is operated to rotate around the rotating shaft 38, the second unlocking operation member 312 can be driven by the extension portion to rotate synchronously around the rotating shaft 38. Thereby, by folding the first unlocking operation member 311, it is possible to realize that both the first unlocking operation member 311 and the second unlocking operation member 312 rotate. Of course, when the second unlocking operation member 312 is folded alone, the connected connecting buckle can be unlocked sequentially in conjunction with each other.

[0120] Embodiment 5 The structural principles of the first connecting buckle 10 and the second connecting buckle 20 in this embodiment are the same, and the outer shapes and dimensions are slightly different. For the sake of simplicity of description, the first male buckle 101 and the second male buckle 201 are collectively referred to as the male buckle structure 80, and the first female buckle 102 and the second female buckle 202 are collectively referred to as the female buckle structure 90.

[0121] Specifically, as shown in FIGS. 11 to 13, the first male buckle 101 and the second male buckle 201 are each provided with a locking tongue 81. The locking tongue 81 protrudes from the joint surface where the male buckle structure 80 and the female buckle structure 90 are joined. The shape of the locking tongue 81 is not limited. In this embodiment, its whole forms a rectangular block-like structure. In other embodiments, the locking tongue 81 may be provided in a structure such as a cylindrical shape.

[0122] As shown in FIGS. 11 to 13, a socket 811 is provided in the lock tongue 81 into which a locking member 93 of the female lock structure 90 can be inserted to achieve the fitting of the male buckle structure 80 and the female lock structure 90. The socket 811 is located on the side surface of the lock tongue 81. Therefore, the opening direction of the socket 811 is perpendicular to the direction in which the lock tongue 81 is inserted into the female lock structure 90.

[0123] The shape of the socket 811 can be set as required. In this embodiment, it is a rectangular groove structure.

[0124] As shown in FIGS. 11 to 13, in order to quickly join the male buckle structure 80 and the female buckle structure 90 (the first male buckle 101 and the first female buckle 102 are joined, and the second male buckle 201 and the second female buckle 202 are joined), a second magnet member 82 is provided in the lock tongue 81. In this embodiment, the second magnet member 82 is selected and used as a rectangular block magnet.

[0125] The female buckle structure 90, that is, the first female buckle 102 and the second female buckle 202, each includes a first housing 91, a second housing 92, and a locking member 93.

[0126] As shown in FIGS. 11 to 13, the first housing 91 and the second housing 92 are fitted and connected, and an installation space for installing the locking member 93 is formed therebetween.

[0127] A lock hole 921 is provided in the second housing 92. The shape of the lock hole 921 conforms to the shape of the lock tongue 81, and the lock tongue 81 can be inserted therein.

[0128] As shown in FIGS. 11 to 13, a magnet holder 922 corresponding to the position of the lock hole 921 is provided in the second housing 92. A magnet mounting hole 9221 is provided in the magnet holder 922, and a first magnet member 94 is provided in the magnet mounting hole 9221. In the present embodiment, the first magnet member 94 is selected and used as a rectangular block-shaped magnet, and the magnet mounting hole 9221 is a rectangular groove.

[0129] As shown in FIGS. 11 to 13, the first magnet member 94 faces the position of the lock hole 921, and the first magnet member 94 is attracted to the second magnet member 82. Therefore, when the lock tongue 81 faces the lock hole 921, the first magnet member 94 and the second magnet member 82 are attracted to each other, so that the lock tongue 81 can be quickly inserted into the lock hole 921.

[0130] As shown in FIGS. 11 to 13, a first side opening 9222 and a second side opening 9223 are provided in the side wall of the magnet holder 922. The first side opening 9222 and the second side opening 9223 are opposed to each other in position and penetrate the lock hole 921 respectively. The first side opening 9222 is for the locking portion 931 to move in and out of the socket 811 of the lock tongue 81. The second side opening 9223 is for the scraping portion 933 to move in and out of the end of the lock tongue 81.

[0131] As shown in FIGS. 11 to 13, the locking member 93 is movably provided between the first housing 91 and the second housing 92. One end is connected to the first pulling string 40 and the second pulling string 50, and the other end is inserted into the socket 811 of the lock tongue 81 and adapted to the lock tongue 81, so that the male buckle structure 80 and the female lock structure 90 are locked and connected. When the locking member 93 is pulled by the first pulling string 40 and the second pulling string 50, the locking member 93 withdraws from the socket 811 of the lock tongue 81, and the male buckle structure 80 and the female buckle structure 90 can be separated.

[0132] As shown in FIGS. 11 to 13, the locking member 93 includes an integrally formed operating portion 932, a locking portion 931, and a scraping portion 933.

[0133] As shown in FIGS. 11 to 13, the operating portion 932 is surrounded by the outer periphery of the magnet holder 922 in order to restrict the displacement range of the locking member 93 and to restrict movement along a straight line. In the present embodiment, the operating portion 932 has a rectangular block-shaped structure.

[0134] As shown in FIGS. 11 to 13, the locking portion 931 is formed to protrude inside the operating portion 932 that can be inserted into the socket 811 of the lock tongue 81 and is adaptable to the lock tongue 81. The shape of the locking portion 931 conforms to the shape of the socket 811. In the present embodiment, it has a rectangular block-shaped structure.

[0135] As shown in FIGS. 11 to 13, further, the locking portion 931 is provided with a rectangular groove in which a third magnet member 95 is embedded.

[0136] As shown in FIGS. 11 to 13, the scraping portion 933 is formed to protrude inside the operating portion 932 and faces the locking portion 931 with a space therebetween. The scraping portion 933 is for pushing out the lock tongue 81 in order to facilitate the separation of the male buckle structure 80 and the female buckle structure 90. The scraping portion 933 is on the opposite side of the second side opening 9223 of the magnet holder 922, and its end can enter into the lock hole 921. When the locking member 93 is pulled, the scraping portion 933 can move to the lock tongue 81 and act on the lock tongue 81. In order to push out the lock tongue 81, the end of the scraping portion 933 is in a wedge shape. When the locking member 93 is inserted into the socket 811, the scraping portion 933 is spaced from the lock tongue 81. When the locking member 93 is pulled and moves in the direction of withdrawing from the socket 811, the scraping portion 933 moves in the direction of the lock tongue 81 and gradually pushes out the lock tongue 81 in the reverse direction of inserting it into the lock hole 921, facilitating the separation of the male buckle structure 80 and the female lock structure 90. Also, the scraping portion 933 and the second side opening 9223 are also used to restrain the linear movement of the locking member 93.

[0137] When the lock tongue 81 of the male buckle structure 80 is not inserted into the lock hole 921, since the first magnet member 94 repels the third magnet member 95, the locking member 93 is held outside the range of the lock hole 921 by the magnetic repulsive force between the first magnet member 94 and the third magnet member 95, and the lock tongue 81 can be easily inserted into the lock hole 921.

[0138] When the lock tongue 81 of the male buckle structure 80 is inserted in alignment with the lock hole 921, the first magnet member 94 and the second magnet member 82 are attracted, and the lock tongue 81 is quickly inserted into the lock hole 921.

[0139] When the locking tang 81 enters the locking hole 921, the second magnet member 82 in the locking tang 81 attracts the third magnet member 95 in the locking member 93 to activate the locking member 93. The locking member 93 moves in the direction of the socket 811 of the locking tang 81 and is inserted into the socket 811, mating with the locking tang 81 so that the male buckle structure 80 is held by the female locking structure 90 and cannot move.

[0140] The first pulling string 40 and the second pulling string 50 are for pulling the locking member 93. In this embodiment, a wire rope is selected and used.

[0141] One end of the first pulling string 40 is connected to the unlocking operation member 31, and the other end is connected to the locking member 93 in the second female lock 202. Specifically, it is connected to the tip of the operating portion 932 of the locking member 93.

[0142] One end of the second pulling string 50 is connected to the unlocking operation member 31, and the other end is connected to the locking member 93 in the second female lock 202. Specifically, it is connected to the tip of the operating portion 932 of the locking member 93.

[0143] Thus, the interlocking quick release device of the present embodiment is formed. When the pressing portions 313 of the first unlocking operation member 311 and the second unlocking operation member 312 of the quick release buckle 30 are pressed against each other, or when the unlocking operation member 31 is rotated in a direction away from the buckle holder 37, the first pulling string 40 and the second pulling string 50 are pulled to different extents. At a certain point, the displacement of the first pulling string 40 being pulled is greater than the displacement of the second pulling string 50 being pulled. Therefore, the locking member 93 in the first connecting buckle 10 preferentially exits completely from within the socket 811 of the locking tang 81 to achieve unlocking of the first connecting buckle 10. On the other hand, as the movement of the first pulling string 40 and the second pulling string 50 continues, the locking member 93 in the second connecting buckle 20 can then exit completely from within the socket 811 to achieve unlocking of the second connecting buckle 20. Therefore, by pressing the first unlocking operation member 311 and the second unlocking operation member 312 against each other, or by rotating the unlocking operation member 31, the effect of sequentially unlocking the first connecting buckle 10 and the second connecting buckle 20 is realized.

[0144] Embodiment 6 Specifically, as shown in FIGS. 14 and 15, the first male buckle 101 and the second male buckle 201 are each provided with a locking tang 81. The locking tang 81 protrudes from the joint surface where the male buckle structure 80 and the female buckle structure 90 are joined. The shape of the locking tang 81 is not limited. In the present embodiment, the locking tang 81 is provided in a cylindrical shape.

[0145]

[0146] ​As shown in FIGS. 14 and 15, a socket 811 is provided in the lock tongue 81 for inserting the locking member 93 of the female lock structure 90 to achieve the fitting of the male buckle structure 80 and the female lock structure 90. The socket 811 is located on the side surface of the lock tongue 81. Therefore, the opening direction of the socket 811 is perpendicular to the direction in which the lock tongue 81 is inserted into the female lock structure 90.

[0147] The shape of the socket 811 may be provided as required. In this embodiment, it is a circular ring groove.

[0148] As shown in FIGS. 14 and 15, in order to quickly join the male buckle structure 80 and the female buckle structure 90 (the first male buckle 101 is joined to the first female buckle 102, and the second male buckle 201 is joined to the second female buckle 202), a second magnet member 82 is provided in the lock tongue 81. In this embodiment, the second magnet member 82 is selected and used as a circular block magnet.

[0149] As shown in FIGS. 14 and 15, the female buckle structure 90, that is, the first female buckle 102 and the second female buckle 202, respectively include a first housing 91, a second housing 92, and a locking member 93.

[0150] As shown in FIGS. 14 and 15, the first housing 91 and the second housing 92 are fitted and connected to form a mounting space for mounting the locking member 93.

[0151] As shown in FIGS. 14 and 15, a lock hole 921 is provided in the second housing 92. The shape of the lock hole 921 conforms to the shape of the lock tongue 81, and the lock tongue 81 can be inserted.

[0152] As shown in FIGS. 14 and 15, a magnet holder 922 corresponding to the position of the lock hole 921 is provided in the second housing 92. A magnet mounting hole 9221 is provided in the magnet holder 922, and a first magnet member 94 is provided in the magnet mounting hole 9221. In the present embodiment, the first magnet member 94 is selected and used as a rectangular block-shaped magnet, and the magnet mounting hole 9221 is a rectangular groove.

[0153] The first magnet member 94 faces the position of the lock hole 921, and the first magnet member 94 is attracted by the second magnet member 82. Therefore, when the lock tongue 81 faces the lock hole 921, the first magnet member 94 and the second magnet member 82 attract each other, so that the lock tongue 81 can be quickly inserted into the lock hole 921.

[0154] As shown in FIGS. 14 and 15, a first side opening 9222 and a second side opening 9223 are provided in the side wall of the magnet holder 922. The first side opening 9222 and the second side opening 9223 are opposed to each other in position and penetrate the lock hole 921 respectively. The first side opening 9222 is for the locking portion 931 to move in and out of the socket 811 of the lock tongue 81. The second side opening 9223 is for the scraping portion 933 to move in and out of the end of the lock tongue 81.

[0155] As shown in FIGS. 14 and 15, the locking member 93 is movably provided between the first housing 91 and the second housing 92. One end is connected to the first pulling string 40 and the second pulling string 50, and the other end is inserted into the socket 811 of the lock tongue 81 and adapted to the lock tongue 81, so that the male buckle structure 80 and the female lock structure 90 are locked and connected. When the locking member 93 is pulled by the first pulling string 40 and the second pulling string 50, the locking member 93 withdraws from the socket 811 of the lock tongue 81, and the male buckle structure 80 and the female buckle structure 90 can be separated.

[0156] As shown in FIGS. 14 and 15, the locking member 93 includes a relatively movable operating portion 932, a locking portion 931, and a scraping portion 933. Here, the locking portion 931 is movable relative to the operating portion 932, and the scraping portion 933 is movable relative to the operating portion 932.

[0157] As shown in FIGS. 14 and 15, the operating portion 932 is surrounded by the outer periphery of the magnet holder 922 in order to restrict the displacement range of the locking member 93 and to restrict movement along a straight line. In the present embodiment, the operating portion 932 has a rectangular block-shaped structure.

[0158] As shown in FIGS. 14 and 15, the locking portion 931 is used to engage with the lock tongue 81, has an independent structure with respect to the operating portion 932, faces the operating portion 932 at a certain distance from the operating portion 932, and is movable under the pulling out of the operating portion 932. The locking portion 931 includes an integral lock main body portion and an upper boss portion. The lock main body portion is plate-shaped, and its end portion is arc-shaped and can be inserted into the socket 811 of the lock tongue 81. The upper boss portion projects from the lock main body portion in order to interact with the operating portion 932.

[0159] As shown in FIGS. 14 and 15, the locking portion 931 and the operating portion 932 are provided in a stacked manner so as to be relatively translatable. When the lock main body portion is joined to the lock tongue 81, the upper boss portion and the operating portion 932 face each other with a gap therebetween. The operating portion 932 can move in the direction of the upper boss portion under the pulling out of the corresponding first pulling string 40 or second pulling string 50 to actuate the upper boss portion, thereby moving the lock main body portion in a direction away from the lock tongue 81 and realizing the release of the engagement between the locking portion 931 and the lock tongue 81.

[0160] Furthermore, a third magnet member 95 is provided on the locking portion 931. The third magnet member 95 can interact with the first magnet member 94 and the second magnet member 82 to realize functions such as locking and unlocking. The third magnet member 95 may repel the second magnet member 82 or attract the second magnet member 8211. Specifically, it can be installed as required, and its installation principle can refer to the patents of CN2021104153735, EP21191582.2, JP202267451, and US17 / 702842. Preferably, the third magnet member 9533 may be provided as follows.

[0161] As shown in FIGS. 14 and 15, the scraping portion 933 is movably provided inside the operating portion 932 and is spaced apart from and opposed to the locking portion 931. The scraping portion 933 is for pushing out the lock tongue 81 in order to facilitate the separation of the male buckle structure 80 and the female buckle structure 90. The scraping portion 933 is on the opposite side of the second side opening 9223 of the magnet holder 922, and its end can enter the lock hole 921. When the locking member 93 is pulled, the scraping portion 933 can move to the lock tongue 81 and act on the lock tongue 81. In order to push out the lock tongue 81, the end of the scraping portion 933 is wedge-shaped.

[0162] To avoid accidental opening, a third elastic member 934 is provided between the scraping portion 933 and the operating portion 932. The third elastic member 934 is provided inside the operating portion 932. Specifically, a restraint groove is provided at a portion of the operating portion 932 facing the locking portion 931. One end of the scraping portion 933 is movably restricted in the restraint groove and cannot escape from the restraint groove, and the other end of the scraping portion 933 extends outside the restraint groove to form a free end. The third elastic member 934 is provided in the restraint groove, with one end abutting against the scraping portion 933 and the other end abutting against the inner wall of the restraint groove.

[0163] As shown in FIGS. 14 and 15, when the driving part 932 moves under the pulling out of the corresponding first pulling string 40 and second pulling string 50, the scraping part 933 moves to the end face of the locking tongue 81 and is pushed out between the locking tongue 81 and the part of the magnet holder 922. Since the scraping part 933 is connected to the third elastic member 934, the scraping part 933 tends to be pressed against the locking tongue 81 to move the locking tongue 81 out of the locking hole 921. At this time, since the locking tongue 81 is still engaged with the locking part 931, the scraping part 933 only has a tendency to move the locking tongue 81 out of the locking hole 921, and cannot directly move the locking tongue 81 out of the locking hole 921. When the operating part 932 continues to move, the operating part 932 can operate the locking part 931, press the locking part 931 in a direction away from the locking hole 921, and release the engagement between the locking part 931 and the locking tongue 81. At this time, the scraping part 933 can move the locking tongue 81 out of the locking hole 921 and separate the male buckle structure 80 from the female locking structure 90.

[0164] Furthermore, as shown in FIGS. 14 and 15, in order to facilitate the return of the locking member 93, a contact part 935 is provided on the outer wall of the operating part 932, and a fourth elastic member 936 is provided between the contact part 935 and the female buckle. When the operating part 932 moves, the fourth elastic member is compressed or has the ability to return the pulling string.

[0165] As shown in FIGS. 14 and 15, one end of the first pulling string 40 is connected to the unlocking operation member 31, and the other end is connected to the locking member 93 in the first female buckle 102, specifically, to the tip of the operating part 932 of the locking member 93.

[0166] As shown in FIGS. 14 and 15, one end of the second pulling string 50 is connected to the unlocking operation member 31, and the other end is connected to the locking member 93 in the second female buckle 202, specifically, to the tip of the operating part 932 of the locking member 93.

[0167] Thus, the interlocking quick release device of the present embodiment is formed. When the pressing portions 313 of the first unlocking operation member 311 and the second unlocking operation member 312 of the quick release buckle 30 are pressed against each other, or when the unlocking operation member 31 is rotated in a direction away from the buckle holder 37, the first pulling string 40 and the second pulling string 50 are pulled to different extents. At a certain point, the displacement of the first pulling string 40 being pulled is greater than the displacement of the second pulling string 50 being pulled. Therefore, the degree of movement of the operating portion 932 in the first connecting buckle 10 is greater than the degree of movement of the operating portion 932 in the second link 20. The locking portion 931 in the first connecting buckle 10 is preferentially actuated to release the engagement with the locking tang 81, separating the first male buckle 101 and the first female buckle 102. On the other hand, as the movement of the first pulling string 40 and the second pulling string 50 continues, the operating portion 932 in the second connecting buckle 20 then actuates the corresponding locking portion 931 to release the engagement between the locking portion 931 and the locking tang 81, separating the second male buckle 201 and the second female buckle 202. Thereby, the effect of sequentially unlocking the first connecting buckle 10 and the second connecting buckle 20 can be realized.

[0168] It should be noted that for the present invention, the quick release buckles 30 in Embodiment 1, Embodiment 2, Embodiment 3, and Embodiment 4 can be used in combination with the first connecting buckle 10 and the second connecting buckle 20 in Embodiment 5 and Embodiment 6 respectively. The configurations of the first connecting buckle 10 and the second connecting buckle 20 may be the same or different. For example, in some embodiments, the first connecting buckle 10 can be set to the configuration of Embodiment 5, and the second connecting buckle 20 can be set to the configuration of Embodiment 6, etc.

[0169] The present invention further provides a bulletproof quick release collar, which includes a collar front sheet 61, a collar rear sheet 62, and the above-described interlocking quick release buckle device as shown in FIG. 1.

[0170] The structures of the front bib sheet 61 and the rear bib sheet 62 themselves can refer to known technologies, and this embodiment will not introduce them.

[0171] The front bib sheet 61 and the rear bib sheet 62 may be connected to each other and worn on the upper body, or it is convenient that they are separated from each other and can be quickly detached and attached.

[0172] In the present invention, one shoulder or both shoulders on one side of the front bib sheet 61 and the rear bib sheet 62 are separably connected by the second connection buckle 20.

[0173] In this embodiment, as shown in FIG. 1, both shoulders of the front bib sheet 61 and the rear bib sheet 62 are connected by two second connection buckles 20. Specifically, one second female buckle 202 is fixedly provided at each of the two shoulder positions of the front bib sheet 61, and one second male buckle 201 is fixedly provided at each of the two shoulder positions of the rear bib sheet 62. The second female buckle 202 can be compatible with the second male buckle 201 to connect the shoulder of the front bib sheet 61 and the shoulder of the rear bib sheet 62. By unlocking between the second female buckle 202 and the second male buckle 201, the shoulder of the front bib sheet 61 and the shoulder of the rear bib sheet 62 can be separated.

[0174] One waist or both waists on one side of the front bib sheet 61 and the rear bib sheet 62 are separably connected by the first connection buckle 10.

[0175] In this embodiment, as shown in FIG. 1, first female buckles 102 are fixedly provided at the left waist position and the right waist position of the front bib sheet 61 respectively, and first male buckles 101 are fixedly provided at the left waist position and the right waist position of the rear bib sheet 62 respectively. By the matching of the first female buckle 102 and the first male buckle 101, the waist of the front bib sheet 61 and the waist of the rear bib sheet 62 can be connected. By releasing the lock between the first female buckle 102 and the first male buckle 101, the waist of the front bib sheet 61 and the waist of the rear bib sheet 62 can be separated.

[0176] The quick release buckle 30 is fixedly provided on the front bib sheet 61, and its structure can refer to Embodiment 1, Embodiment 2, Embodiment 3, and Embodiment 4.

[0177] The first pulling string 40 and the second pulling string 50 are provided on the front bib sheet 61.

[0178] In Embodiment 1 and Embodiment 2 of the quick release buckle 30, when the first unlocking operation member 311 and the second unlocking operation member 312 of the quick release buckle 30 are pressed against each other, the first connecting buckle 10 is first unlocked so that the waist positions of the front bib sheet 61 and the rear bib sheet 62 are first released, and then the second connecting buckle 20 is unlocked, and the shoulder positions of the front bib sheet 61 and the rear bib sheet 62 are released, and the front bib sheet 61 and the rear bib sheet 62 are completely separated to achieve quick release.

[0179] Regarding the quick release buckle 30 in Embodiment 3 and Embodiment 4, when the unlocking operation member 31 is rotated in a direction away from the buckle holder 37, the first connecting buckle 10 is unlocked such that the waist positions of the front bib sheet 61 and the rear bib sheet 62 are released first, and then the second connecting buckle 20 is unlocked, and the shoulder positions of the front bib sheet 61 and the rear bib sheet 62 are released, and the front bib sheet 61 and the rear bib sheet 62 are completely separated, realizing a quick release.

[0180] The waists of the front bib sheet 61 and the rear bib sheet 62 are unlocked first, and then the shoulders are unlocked, whereby the self-weight of the bulletproof bib can be utilized to assist in unlocking the second connecting buckle 20 at the shoulder position. Also, if the waist is unlocked later and the shoulder is unlocked first, due to the self-weight of the bulletproof bib, the released bulletproof bib will fall down and get caught on the feet.

[0181] Furthermore, in order to prevent the first link 10 and the second link 20 from being unable to be unlocked due to a failure of the quick release buckle 30, the first pulling string 40, or the second pulling string 50, a manual unlocking operation portion 96 is provided on the first link 10 and the second link 20. When the manual unlocking operation portion 96 is operated, the corresponding first connecting buckle 10 and second connecting buckle 20 are unlocked.

[0182] In some embodiments, the manual unlocking operation portion 96 is provided on the operating portion 932, and a part or all of it is exposed outside the female buckle. The user can move the operating portion 932 by pressing or pulling the manual unlocking operation portion 96, thereby moving the unlocking portion 931 and the scraping portion 933 to achieve unlocking.

[0183] In some embodiments, a pulling string extending outside the female buckle is connected to the operating part 932, the pulling direction of the pulling string is the same as that of the first pulling string 40 and the second pulling string 50, and the pulling string functions as the manual unlocking operation part 96. When the user pulls the pulling string, the operating part 932 can move in a direction away from the locking hole 921 to move the locking part 931 and the scraping part 933 to achieve unlocking.

[0184] Although the present invention has been disclosed by the above embodiments, the scope of the present invention is not limited thereto. Without departing from the concept of the present invention, the above-mentioned members can be replaced by similar or equivalent elements understood by those skilled in the art.
