Description

Technical Field

[0001] The utility model relates to the technical field of belt buckles, and more particularly to a belt buckle and a belt. Background Art

[0002] The locking structure of the existing belt buckle is a rotating top lock, which is locked and unlocked by rotating the lock block. Its principle is lever-type friction locking. If it is pulled hard, it is easy to move. It is very easy to become loose after long-term use, and there is a hidden danger that it cannot be fastened during use. Utility Model Content

[0003] The purpose of the utility model is to overcome the problem that the existing belt buckle can withstand a small pulling force and is not reliable to use, and to provide a belt buckle that can withstand a larger pulling force and is more reliable in locking and unlocking.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A belt buckle comprises a mother seat and a sub-buckle which are plugged into each other; further comprising a locking structure for locking the mother seat and the sub-buckle, wherein the locking structure comprises a first elastic lock component and a second elastic lock component, wherein the first elastic lock component and the second elastic lock component are movably mounted on both sides of the vertical direction in which the mother seat and the sub-buckle are plugged into each other, and the first elastic lock component and the second elastic lock component are also nested and plugged into each other; pressing the two elastic lock components simultaneously can unlock the sub-buckle; releasing the two elastic lock components can lock the sub-buckle.

[0006] This utility model's belt buckle utilizes a double-sided latching structure formed by two cross-arranged elastic lock assemblies. This structure provides locking power through bidirectional movement. Both the first and second elastic lock assemblies possess elastic forces. When the elastic forces are zero, the mother base and the child buckle are locked, maintaining their connection and resisting certain external forces. When force is applied from the first and second elastic lock assemblies toward the center of the child buckle, the elastic forces reach their maximum due to the pressure, unlocking the mother base and the child buckle. The child buckle can be withdrawn from the mother base, achieving separation. This cross-locking design evenly transmits external tension on the belt, allowing the belt buckle to withstand greater tension.

[0007] Furthermore, the first elastic lock assembly includes a first lock frame and a first spring, and the second elastic lock assembly includes a second lock frame and a second spring. The first lock frame and the second lock frame are nested and plugged into each other, and the first lock frame and the second lock frame are also movably plugged into the mother seat and the sub-buckle. One end of the first spring is connected to the inner side of the first lock frame, and the other end is connected to the outer side of the second lock frame. One end of the second spring is connected to the inner side of the second lock frame, and the other end is connected to the outer side of the first lock frame; when the first spring and the second spring are both in their original state, the second lock frame close to the first spring side and the first lock frame close to the second spring side both apply elastic force toward the sub-buckle. The first lock frame and the second lock frame are cross-nested and arranged, and the first spring and the second spring are used to provide elastic force. When a pressing force toward the sub-buck is applied to the first lock frame, the first spring can be used to drive the second lock frame to move in the direction away from the sub-buck. Similarly, when a pressing force toward the sub-buck is applied to the second lock frame, the second spring can be used to drive the first lock frame to move in the direction away from the sub-buck. Therefore, the locking structure of the utility model is different from the conventional press-to-lock structure. In the utility model, pressing and applying force from both sides of the sub-buck toward the middle of the sub-buck at the same time is an unlocking operation, not a locking operation; it also has the function of preventing accidental touch. When the belt buckle is in the locked state, the first spring and the second spring naturally extend, pushing the two lock frames into the buckle locking position to achieve locking. At this time, the first lock frame and the second lock frame limit the sub-buckle to prevent the sub-buckle from separating from the mother seat; when the belt needs to be unlocked, press the two ends of the locking structure to actively compress the first spring and the second spring to the limited position. At this time, the first lock frame and the second lock frame exit the limit position of the sub-buckle, releasing the limit constraint to achieve unlocking, and then the sub-buckle can be pulled out from the mother seat to separate the sub-buckle from the mother seat.

[0008] Furthermore, a first mounting position is provided within the first lock frame, and the first spring is mounted at the first mounting position; a second mounting position is provided within the second lock frame, and the second spring is mounted at the second mounting position. Both the first mounting position and the second mounting position may be grooves, and the first mounting position facilitates positioning of the first spring during installation; the second mounting position facilitates positioning of the second spring during installation.

[0009] Furthermore, a slot is provided on the mother seat, and a plug-in portion is provided at the end of the sub-button, and the plug-in portion is plugged into the slot; the first lock frame and the second lock frame are both arranged perpendicular to the plug-in direction of the plug-in portion and the slot, and both are arranged across both sides of the plug-in portion. The plug-in portion and the slot cooperate with each other to achieve the plug-in connection between the sub-button and the mother seat. The first lock frame and the second lock frame are both arranged perpendicular to the plug-in direction of the plug-in portion and the slot, which can facilitate unlocking when force is applied, and can also facilitate locking in a non-forced state. Of course, within the scope of cognition of those skilled in the art, the first lock frame and the second lock frame do not have to be arranged perpendicular to the plug-in direction of the plug-in portion and the slot, and can also be arranged in other directions. The vertical direction is the optimal implementation method.

[0010] Furthermore, the female base is provided with a mounting through-hole, the mounting through-hole being perpendicular to and interconnected with the slot, and a first limiting slot and a second limiting slot being respectively provided on either side of the plug-in portion; the first elastic lock assembly and the second elastic lock assembly are both mounted within the mounting through-hole; the first lock frame is provided with a first limiting portion, the first limiting portion abutting the second limiting slot, with the end of the first lock frame near the first limiting slot protruding from one end of the mounting through-hole; and the second lock frame is provided with a second limiting portion, the second limiting portion abutting the first limiting slot, with the end of the second lock frame near the second limiting slot protruding from the other end of the mounting through-hole. The provision of the mounting through-holes facilitates the installation and inter-nesting arrangement of the first and second elastic lock assemblies. When the locking structure is locked, the first and second lock frames restrict the sub-buckle via the first and second limiting slots, preventing the sub-buckle from accidentally detaching from the female base when the belt is subjected to tension. Preferably, the first limiting portion is a protrusion provided on the inner side of the first lock frame, and the second limiting portion is a protrusion provided on the inner side of the second lock frame. The first limiting portion abuts the second limiting groove, and the second limiting portion abuts the first limiting groove, respectively, to limit the sub-buckle from both sides. The end of the first lock frame away from the second lock frame and the end of the second lock frame away from the first lock frame are both protruded from both ends of the mounting through-hole. This facilitates applying force to the locking structure from both sides of the sub-buckle, that is, both sides of the mother seat, to achieve unlocking. The above-mentioned locking structure constitutes a frame-type locking structure, which can ensure balanced force when locking.

[0011] Furthermore, the base includes a base body and a cover plate, the mounting through hole is located between the base body and the cover plate, the slot is located in the base body, and the base body and the cover plate are detachably connected. The detachable cover plate and base body structure facilitates the installation of the first elastic lock assembly and the second elastic lock assembly.

[0012] Furthermore, the base body is provided with a third limiting groove and a fourth limiting groove, each located on either side of the mounting through-hole and both communicating with the mounting through-hole. A third limiting portion is provided on the outside of the first lock frame, plugging into the third limiting groove; and a fourth limiting portion is provided on the outside of the second lock frame, plugging into the fourth limiting groove. The third limiting portion abuts the third limiting groove, allowing the first lock frame to be positioned from the outside of the first lock frame using the limiting function of the base body. Similarly, the fourth limiting portion abuts the fourth limiting groove, allowing the second lock frame to be positioned from the outside of the second lock frame using the limiting function of the base body. Because the locking structure moves in a direction perpendicular to the insertion direction of the sub-clasp and the mother seat, the third and fourth limiting grooves serve as movable limiting points, which are the same as the unlocking position of the sub-clasp, realizing unlocking when in place. That is, when the first lock frame and the second lock frame are pressed, the end of the third limiting portion abuts the end of the third limiting groove, and the end of the fourth limiting portion abuts the end of the fourth limiting groove. The first lock frame can compress the first spring to drive the second lock frame out of the second limiting groove on the sub-clasp, and the second lock frame can compress the second spring to drive the first lock frame out of the first limiting groove on the sub-clasp. This operation can reduce or avoid the possibility of unlocking failure in an emergency.

[0013] Furthermore, the mother base is provided with a first recess and a second recess on both sides of the mounting through hole, respectively. A first limiting step is provided at the bottom of the first recess, and the end of the first elastic lock assembly is located in the first recess and protrudes from the first limiting step; a second limiting step is provided at the bottom of the second recess, and the end of the second elastic lock assembly is located in the second recess and protrudes from the second limiting step. This arrangement can achieve an anti-accidental touch design: the pressing surfaces of the first and second lock frames are both lower than the outer boundary of the mother base body and can also be lower than the outer boundary of the sub-button. The mother base body blocks external extrusion objects to achieve anti-accidental touch. The first and second lock frames must be pressed into place at the same time to unlock, and it can also prevent accidental touch from being caused by pressing on one side.

[0014] Furthermore, a guide structure is provided at the end of the plug-in portion. Preferably, the guide structure is provided with an end chamfer, and the provision of the guide structure can facilitate the plugging of the sub-button and the female seat.

[0015] The present invention also provides a waist belt comprising a waist belt body and the aforementioned waist belt buckle, wherein a mother seat is fixedly mounted on one end of the waist belt body, and a child buckle is movably connected to the waist belt body. The waist belt of the present invention utilizes a cross-lock design to evenly transmit tension, thereby increasing the tension that the waist belt body can withstand, while also providing a more reliable locking design and preventing accidental touches.

[0016] The beneficial effects of the utility model are:

[0017] (1) The locking structure is a frame-type locking structure, which locks the buckle in the middle of the frame to ensure balanced locking force.

[0018] (2) The first lock frame and the second lock frame form a nested plug-in structure, so that the two lock frames provide spring support points for each other and provide balanced locking elastic force. The structure is simple and reliable.

[0019] (3) The locking structure moves in a direction perpendicular to the direction of insertion between the mother seat and the child buckle, and is provided with a third limiting portion and a third limiting groove, and a fourth limiting portion and a fourth limiting groove as movable limiting points, which are the same as the unlocking positions of the first limiting portion and the second limiting groove, and the second limiting portion and the first limiting groove of the child buckle, so that the buckle is unlocked as soon as it is in position. A single operation can reduce or avoid the possibility of unlocking failure in an emergency, thus overcoming the problem in the prior art that the buckle cannot be quickly disengaged when unlocking the belt buckle using rotational unlocking.

[0020] (4) The pressing surfaces of the first lock frame and the second lock frame are both lower than the outer boundary of the mother seat body, and the mother seat body blocks external extrusion objects to prevent accidental touch. The first lock frame and the second lock frame must be pressed into place at the same time to unlock, and it can also prevent accidental touch caused by unilateral pressing.

[0032] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0033] Example 1

[0034] like Figures 1 to 7 The figure shows an embodiment of a belt buckle of the present invention, comprising a mother seat 1 and a sub-buckle 2 that are plugged into each other; it also includes a locking structure for locking the mother seat 1 and the sub-buckle 2, the locking structure comprising a first elastic lock component 3 and a second elastic lock component 4, the first elastic lock component 3 and the second elastic lock component 4 are respectively movably mounted on both sides of the vertical direction of the mutual plugging of the mother seat 1 and the sub-buckle 2, the first elastic lock component 3 and the second elastic lock component 4 are also nested and plugged into each other; pressing the two elastic lock components at the same time can unlock the sub-buckle 2; releasing the two elastic lock components can lock the sub-buckle 2.

[0035] The belt buckle of this utility model adopts a double-sided locking structure formed by two cross-arranged elastic lock components, which provide locking power through bidirectional movement. The first elastic lock component 3 and the second elastic lock component 4 both have elastic force. When the elastic force is zero, the mother base 1 and the child buckle 2 are in a locked state, which can keep the child buckle 2 and the mother base 1 in a plugged state and resist certain external forces. When the first elastic lock component 3 and the second elastic lock component 4 are respectively applied toward the middle of the child buckle 2, the elastic force reaches its maximum due to pressure, and the mother base 1 and the child buckle 2 are in an unlocked state, allowing the child buckle 2 to be withdrawn from the mother base 1 and separated from the mother base 1. Through the cross-locking design, the utility model can evenly transmit external tension on the belt, allowing the belt buckle to withstand greater tension.

[0036] Specifically, the first elastic lock assembly 3 includes a first lock frame 31 and a first spring 32, and the second elastic lock assembly 4 includes a second lock frame 41 and a second spring 42. The first lock frame 31 and the second lock frame 41 are nested and plugged into each other, and the first lock frame 31 and the second lock frame 41 are also movably plugged into the mother seat 1 and the sub-buckle 2. One end of the first spring 32 is connected to the inner side of the first lock frame 31, and the other end is connected to the outer side of the second lock frame 41. One end of the second spring 42 is connected to the inner side of the second lock frame 41, and the other end is connected to the outer side of the first lock frame 31; when the first spring 32 and the second spring 42 are both in their original state, the second lock frame 41 close to the first spring 32 side and the first lock frame 31 close to the second spring 42 side both apply elastic force toward the sub-buckle 2.

[0037] The first lock frame 31 and the second lock frame 41 are cross-nested and arranged, and the first spring 32 and the second spring 42 provide elastic force. When a pressing force toward the buckle 2 is applied to the first lock frame 31, the first spring 32 can be used to drive the second lock frame 41 to move in the direction away from the buckle 2. Similarly, when a pressing force toward the buckle 2 is applied to the second lock frame 41, the second spring 42 can be used to drive the first lock frame 31 to move in the direction away from the buckle 2. Therefore, at the same time, from the first lock frame 31 and the second lock frame 41 to the inside, that is, from the first lock frame 31 to the second lock frame 41 and the second lock frame 41 to the inside, When force is applied from the second lock frame 41 toward the first lock frame 31, the first lock frame 31 and the second lock frame 41 can be simultaneously moved away from the sub-buckle 2, thereby achieving the unlocking effect. If force is applied from only one side, either the first lock frame 31 will lock one side of the sub-buckle 2, or the second lock frame 41 will lock one side of the sub-buckle 2, so that the sub-buckle 2 cannot be separated from the mother seat 1; therefore, the locking structure of the present invention is different from the conventional press-to-lock structure. In the present invention, applying force from both sides of the sub-buckle 2 toward the middle of the sub-buckle 2 at the same time is an unlocking operation, not a locking operation; it also has the function of preventing accidental touch. When the belt buckle is in the locked state, the first spring 32 and the second spring 42 are naturally stretched, pushing the two lock frames into the buckle locking position to achieve locking. At this time, the first lock frame 31 and the second lock frame 41 limit the sub-buckle 2 to prevent the sub-buckle 2 from being separated from the mother seat 1; when the belt needs to be unlocked, press the two ends of the locking structure to actively compress the first spring 32 and the second spring 42 to the limited position. At this time, the first lock frame 31 and the second lock frame 41 exit the limit position of the sub-buckle 2, releasing the limit constraint to achieve unlocking, and then the sub-buckle 2 can be pulled out from the mother seat 1 to separate the sub-buckle 2 from the mother seat 1.

[0038] Preferably, a first mounting position 311 is defined within the first lock frame 31, and the first spring 32 is mounted at the first mounting position 311; a second mounting position 411 is defined within the second lock frame 41, and the second spring 42 is mounted at the second mounting position 411. Both the first mounting position 311 and the second mounting position 411 may be grooves, and the provision of the first mounting position 311 facilitates positioning of the first spring 32 during installation; the provision of the second mounting position 411 facilitates positioning of the second spring 42 during installation.

[0039] Among them, the mother seat 1 is provided with a slot 111, and the end of the sub-button 2 is provided with a plug-in portion 21, which is plugged into the slot 111; the first lock frame 31 and the second lock frame 41 are both arranged perpendicular to the plug-in direction of the plug-in portion 21 and the slot 111, and both are arranged across both sides of the plug-in portion 21. The plug-in portion 21 and the slot 111 cooperate with each other to achieve the plug-in connection between the sub-button 2 and the mother seat 1. The first lock frame 31 and the second lock frame 41 are both arranged perpendicular to the plug-in direction of the plug-in portion 21 and the slot 111, which can facilitate unlocking when force is applied, and can also facilitate locking in a non-forced state. Of course, within the scope of cognition of those skilled in the art, the first lock frame 31 and the second lock frame 41 do not have to be arranged perpendicular to the plug-in direction of the plug-in portion 21 and the slot 111, and can also be arranged in other directions. The vertical direction is the optimal implementation method.

[0040] Furthermore, a guide structure 213 is provided at the end of the plug-in portion 21. Preferably, the guide structure 213 is chamfered at the end, and the provision of the guide structure 213 facilitates the plugging of the sub-button 2 and the female seat 1.

[0041] The locking cam 212 is engaged with the locking cam 214 and the locking cam 216, and the cam 218 is engaged with the first and second locking cams 212. When the locking cam 214 is engaged with the first and second locking cams 216, the locking cam 216 is engaged with the first and second locking cams 212. When the locking cam 214 is engaged with the locking cam 216, the locking cam 216 is engaged with the first and second locking cams 212.

[0042] The provision of the mounting through-hole 112 facilitates the installation and mutual nesting of the first elastic lock assembly 3 and the second elastic lock assembly 4. When the locking structure is locked, the first lock frame 31 and the second lock frame 41 restrict the sub-buckle 2 through the first limiting groove 211 and the second limiting groove 212, thereby preventing the sub-buckle 2 from accidentally detaching from the mother seat 1 when the belt is subjected to tension. Preferably, the first limiting portion 312 is a protrusion provided on the inner side of the first lock frame 31, and the second limiting portion 412 is a protrusion provided on the inner side of the second lock frame 41. The first limiting portion 312 abuts against the second limiting groove 212, and the second limiting portion 412 abuts against the first limiting groove 211, respectively limiting the sub-buckle 2 from both sides. The ends of the first locking frame 31 away from the second locking frame 41 and the ends of the second locking frame 41 away from the first locking frame 31 both protrude from the mounting through-hole 112 at both ends, making it easy to apply force to the locking structure from both sides of the sub-clasp 2, that is, both sides of the mother base 1, to achieve unlocking. The above-mentioned locking structure constitutes a frame-type locking structure, which can ensure balanced locking force.

[0043] As an improvement to this embodiment, the female connector 1 includes a female connector body 11 and a cover plate 12. The mounting through hole 112 is located between the female connector body 11 and the cover plate 12. The slot 111 is located in the female connector body 11. The female connector body 11 and the cover plate 12 are detachably connected. The detachable connection between the cover plate 12 and the female connector body 11 facilitates the installation of the first elastic lock assembly 3 and the second elastic lock assembly 4.

[0044] As an improvement to this embodiment, a third limiting groove 113 and a fourth limiting groove 114 are provided on the female seat body 11, and the third limiting groove 113 and the fourth limiting groove 114 are respectively located on both sides of the mounting through hole 112 and are both connected to the mounting through hole 112; a third limiting portion 313 is provided on the outer side of the first lock frame 31, and the third limiting portion 313 is plugged into the third limiting groove 113; a fourth limiting portion 413 is provided on the outer side of the second lock frame 41, and the fourth limiting portion 413 is plugged into the fourth limiting groove 114.

[0045] The third limiting portion 313 abuts against the third limiting groove 113, and the moving position of the first lock frame 31 can be limited from the outside of the first lock frame 31 by utilizing the limiting of the female base 1 body; similarly, the fourth limiting portion 413 abuts against the fourth limiting groove 114, and the moving position of the second lock frame 41 can be limited from the outside of the second lock frame 41 by utilizing the limiting of the female base body 11. Because the locking structure moves in a direction perpendicular to the insertion direction of the sub-clasp 2 and the base 1, the third limiting groove 113 and the fourth limiting groove 114 serve as movable limiting points, which are the same as the unlocking position of the sub-clasp 2, realizing unlocking when in place. That is, when the first lock frame 31 and the second lock frame 41 are pressed, the end of the third limiting portion 313 abuts against the end of the third limiting groove 113, and the end of the fourth limiting portion 413 abuts against the end of the fourth limiting groove 114. The first lock frame 31 can compress the first spring 32 to drive the second lock frame 41 out of the second limiting groove 212 on the sub-clasp 2, and the second lock frame 41 can compress the second spring 42 to drive the first lock frame 31 out of the first limiting groove 211 on the sub-clasp 2. This single operation can reduce or avoid the possibility of unlocking failure in an emergency.

[0046] Example 2

[0047] This embodiment is an embodiment of a belt buckle. This embodiment is similar to Example 1, except that the female seat 1 is provided with a first recessed portion 13 and a second recessed portion 14 on both sides of the mounting through hole 112, and a first limiting step 131 is provided at the bottom of the first recessed portion 13. The end of the first elastic lock component 3 is located in the first recessed portion 13 and protrudes from the first limiting step 131; the bottom of the second recessed portion 14 is provided with a second limiting step 141, and the end of the second elastic lock component 4 is located in the second recessed portion 14 and protrudes from the second limiting step 141.

[0048] Such a setting can achieve an anti-accidental touch design: the pressing surfaces of the first lock frame 31 and the second lock frame 41 are both lower than the outer boundary of the mother seat 1 body, and can also be lower than the outer boundary of the sub-button 2. The mother seat 1 body blocks external extrusion objects to achieve anti-accidental touch. The first lock frame 31 and the second lock frame 41 must be pressed at the same time so that both are pressed into place to unlock, and it can also prevent accidental touch from being caused by unilateral pressing.

[0049] Example 3

[0050] This embodiment is an embodiment of a belt, including a belt body and the belt buckle as described above. The mother seat 1 is fixedly mounted on one end of the belt body, and the sub-buckle 2 is movably connected to the belt body.

[0051] The waist belt of the utility model can evenly transmit the pulling force through the cross-lock design, so that the waist belt body can withstand greater pulling force, and has a more reliable locking design and can also prevent accidental touch.

[0052] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
