[0039] Figure 1 , Figure 2 and Figure 4 The locking structure 10 in one embodiment of the utility model is shown. Figure 1 , Figure 2 and Figure 4 As shown, the locking structure 10 includes a first locking module 1 and a second locking module 2. Through the cooperation between the first locking module 1 and the second locking module 2, the installation locking and disassembly unlocking of the two can be realized. It can be understood that the locking structure 10 is applicable to any detachable connection device that needs to be installed and disassembled, for example, it is applicable to emergency backpack equipment. In the actual use scenario of emergency backpack equipment, the first locking module 1 and the second locking module 2 can be respectively set on the emergency communication equipment and the backpack, so that the emergency communication equipment and the backpack can be quickly fixed or unlocked through the cooperation of the first locking module 1 and the second locking module 2, without the assistance of additional structures, which greatly improves the emergency scene response speed and also improves the user experience.

[0040] Combined with Figure 3 As shown, the first locking module 1 may include a first mounting member 11 and a shift block assembly 12 disposed on the first mounting member 11. The second locking module 2 may include a mounting seat 21 provided with a sliding groove 211, a locking tongue assembly 22 on the mounting seat 21 that can move back and forth between facing the sliding groove 211 and facing away from the sliding groove 211, and a first elastic member 231 that provides an elastic force for the locking tongue assembly 22 toward the sliding groove 211; the sliding groove 211 includes a locking position 2112, and the locking tongue assembly 22 extends into the sliding groove under the elastic force of the first elastic member 231.

[0041] like Figures 6a to 6cAs shown, the installation and locking process is: when the shift block assembly 12 moves toward the locking position 2112, the shift block assembly 12 pushes the lock tongue assembly 22 to move the lock tongue assembly 22 back to the sliding groove 211, so as to make way for the shift block assembly 12; after the shift block assembly 12 moves to the locking position 2112, the lock tongue assembly 22 is reset and extends into the sliding groove 211 under the action of the elastic force of the first elastic member 231, thereby locking the shift block assembly 12.

[0042] The shift block assembly 12 is rotatably disposed in the sliding groove 211, and during the rotation process, the lock tongue assembly 22 can be pushed to move the lock tongue assembly 22 away from the sliding groove 211 to make way for the shift block assembly 12. Figures 7a to 7f As shown, the disassembly and unlocking process is: rotate the shift block assembly 12, and the shift block assembly 12 pushes the lock tongue assembly 22 during the rotation process so that the lock tongue assembly 22 moves away from the sliding groove 211 to make way for the shift block assembly 12; the shift block assembly 12 moves outward from the locking position 2112 of the sliding groove 211 and escapes from the sliding groove 211 to complete the unlocking; the lock tongue assembly 22 is reset and extends into the sliding groove 211 under the action of the elastic force of the first elastic member 231.

[0043] For ease of description, the components in the locking structure 10 are defined as including upper and lower ends, left and right sides, and front and back sides.

[0044] Combination Figure 3 , Figure 5 As shown, the shift block assembly 12 may include a shaft portion 121, and the lock tongue assembly 22 may include a lock tongue 221. The first locking module 1 and the second locking module 2 are locked by the cooperation between the shaft portion 121 and the lock tongue 221. It can be understood that the sliding groove 211 can be arranged close to one side of the mounting seat 21, and the lock tongue 221 can be arranged between the sliding groove 211 and the other side of the mounting seat 21, and can move back and forth between the sliding groove 211 and the back of the sliding groove 211.

[0045] The locking tongue 221 is connected to the sliding groove 211, so that the locking tongue 221 can pass through the sliding groove 211. When the locking tongue 221 moves away from the sliding groove 211, it can move to a position where the locking tongue 221 leaves the sliding groove 211 to avoid blocking the passage of the shaft 121. The locking tongue 221 can move from one side of the sliding groove 211 to the other side of the sliding groove 211, so that the locking effect is better.

[0046] In this embodiment, the locking tongue 221 is provided with an inclined surface 2211 at the end facing away from the locking position 2112, and the shaft portion 121 abuts against the inclined surface 2211 through the arc surface. The shaft portion 121 can be provided in a cylindrical shape, so that when the shaft portion 121 moves toward the locking position 2112 of the sliding groove 211, the shaft portion 121 abuts against the inclined surface 2211 of the locking tongue 221 through its arc surface (such as Figure 6a As shown in FIG. 2 , as the shaft portion 121 continues to move, a thrust is provided to the locking tongue 221 to move the locking tongue 221 away from the sliding groove 211, so that the locking tongue 221 gives way, and the shaft portion 121 can continue to move to the locking position 2112.

[0047] In other embodiments, the shaft 121 and the locking tongue 221 may cooperate in other ways, as long as the shaft 121 can push the locking tongue 221 to move away from the sliding slot 211 when the shaft 121 moves toward the locking position 2112 of the sliding slot 211 .

[0048] And, if Figure 6c As shown, when the locking tongue 221 passes through the sliding groove 211, the distance L1 between one end of the locking tongue 221 close to the bottom end of the sliding groove 211 and the bottom end of the sliding groove 211 is adapted to the corresponding size of the shaft portion 121, for example, the former is slightly larger than the latter, so that when the shaft portion 121 moves to the locking position 2112, the locking tongue 221 passes through the sliding groove 211, which can prevent the shaft portion 121 from moving outward, thereby locking the shaft portion 121 in the locking position 2112, that is, realizing the installation and locking of the first locking module 1.

[0049] The first elastic member 231 can be implemented by a spring, that is, the first elastic member 231 can be a first spring, and the first elastic member 231 is disposed on the side of the lock tongue 221 away from the sliding groove 211, thereby providing the lock tongue 221 with an elastic force toward the sliding groove 211. It can be understood that when the shaft portion 121 is released from the locking position 2112, the shaft portion 121 does not block the lock tongue 221, so the lock tongue 221 is reset and extends into the sliding groove 211 under the action of the first elastic member 231.

[0050] Combination Figures 3 to 5 As shown, the shift block assembly 12 may include a shift piece 122 , and the lock tongue assembly 22 may include a lock column 222 . The first locking module 1 can be disassembled and unlocked from the second locking module 2 by the cooperation between the shift piece 122 and the lock column 222 .

[0051] The sliding groove 211 can pass through both sides of the mounting seat 21; the shifting block assembly 12 can be rotatably arranged in the sliding groove 211, and the shifting piece 122 can abut against the locking column 222 during the rotation process to push the locking tongue assembly 22 to move. Figure 7b As shown, it can be understood that unlocking can be achieved by rotating the first locking module 1, which is simple to operate, can prevent mis-locking, and improve reliability.

[0052] In this embodiment, the shift block assembly 12 includes a shaft portion 121 and a shift piece 122, and the lock tongue assembly 22 includes a lock tongue 221 and a lock column 222. Figure 3As shown, one end of the shaft 121 is disposed on the first mounting member 11, and the paddle 122 is disposed on the other end of the shaft 121. It can be understood that one end of the shaft 121 can be fixed to one surface of the first mounting member 11 by means of a screw 3, and the paddle 122 is fixed to the end of the shaft 121 away from the first mounting member 11 by means of a screw 3, and the first mounting member 11, the shaft 121, and the paddle 122 are integrated into one body, so that the shaft 121 and the paddle 122 can be rotated or moved by rotating or moving the first mounting member 11.

[0053] Combination Figure 3 , Figure 5 and Figure 7b As shown, the lock column 222 is arranged on one surface of the lock tongue 221, and the lock column 222 and the lock tongue 221 can be an integral structure formed by an integral molding process, or the two are connected as a whole; and the lock column 222 protrudes outward from the lock tongue 221. The paddle 122 includes an abutting surface 1221 corresponding to the lock column 222, and the abutting surface 1221 is located on the surface where the paddle 122 is located in the thickness direction. Among them, the lock column 222 can be arranged in a columnar shape. The paddle 122 contacts the lock column 222 through the abutting surface 1221, and the abutting surface 1221 can be arranged in an arc-shaped track. When the first locking module 1 rotates toward the side where the lock column 222 is located, the paddle 122 abuts against the lock column 222 through its abutting surface 1221, and pushes the lock column 222 to move back to the sliding groove 211. It can be understood that the track of the abutting surface 1221 of the paddle 122 can be set in a shape that protrudes outward toward the side where the locking tongue 221 is located.

[0054] like Figure 2 , Figure 3 As shown, the locking structure 10 also includes a limiting structure to further prevent the emergency communication device from being unlocked and falling out during normal use. The limiting structure may include a positioning portion 13 disposed on the first mounting member 11 and located on both sides of the shift block assembly 12, and a positioning groove 24 correspondingly disposed on the second locking module 2. The positioning groove 24 is disposed on a side facing away from the lock column 222, and the positioning portion 13 and the positioning groove 24 are detachably plugged in and matched. The positioning portion 13 may be a positioning pin, and the positioning groove 24 may be disposed in a long strip shape and extend vertically. And / or,

[0055] like Figure 4 , Figure 7a As shown, the limiting structure may include a second mounting member 25 disposed on the mounting seat 21, and the second mounting member 25 is provided with two limiting walls 251 on a side facing the lock tongue assembly 22, and the two limiting walls 251 are arranged at intervals and correspond to the two sides of the paddle 122 respectively. It can be understood that the second mounting member 25 is arranged close to the surface where the lock column 222 is located, and the two limiting walls 251 correspond to the two sides of the paddle 122. The second mounting member 25 can be fixed to the mounting seat 21 by screws 3.

[0056] It can be understood that "and / or" means that one of the two structures can be provided, or both structures can be provided at the same time. In this embodiment, the limiting structure can include both of the above structures to achieve limiting anti-rotation at two locations respectively, ensuring that it will not rotate after being installed in place, making the anti-rotation effect better and more reliable. Of course, in other embodiments, the limiting structure can include one of the above structures, and the limiting anti-rotation function can also be achieved.

[0057] Combination Figure 7a As shown, the paddle assembly 12 can move back and forth between the second mounting member 25 and the back of the second mounting member 25 in the sliding groove 211, so that the first locking module 1 can be released from the limit by moving back to the second mounting member 25. Among them, the limit wall 251 and the mounting seat 21 are arranged at a distance, and the distance between the limit wall 251 and the mounting seat 21 is greater than the thickness of the paddle 122. It can be understood that by moving the first locking module 1 back to the second mounting member 25 and moving the paddle 122 to the gap position between the limit wall 251 and the mounting seat 21, the limit of the paddle 122 is released, and the movement of the paddle 122 is not affected, so that the paddle 122 can be matched with the lock column 222.

[0058] In this embodiment, among the limiting walls 251 respectively located on both sides, the spacing distance between the end of the limiting wall 251 close to the lock column 22 and the mounting seat 21 is greater than the thickness of the paddle 122, so that the paddle 122 can cooperate with the lock column 222 by rotating after the limit is released; the spacing distance between the limiting wall 251 away from the lock column 222 and the mounting seat 21 can be less than the thickness of the paddle 122, which can prevent the paddle 122 from rotating toward the side away from the lock column 222, thereby playing an anti-mistake effect.

[0059] The insertion depth of the positioning portion 13 and the positioning groove 24 is adapted to the distance that the paddle 122 moves out of the limiting wall 251. It can be understood that the insertion depth of the positioning portion 13 and the positioning groove 24 can be close to the distance that the paddle 122 moves out of the limiting wall 251, for example, the two are equal, slightly larger or slightly smaller, so that when the first locking module 1 is moved a distance away from the second mounting member 25, the paddle 122 and the positioning portion 13 are correspondingly disengaged from the limiting wall 251 and the positioning groove 24, thereby releasing the limit, and then the first locking module 1 can be rotated to achieve unlocking.

[0060] like Figure 2 , Figure 3 , Figure 7aAs shown, in this embodiment, both sides of the first mounting member 11 are respectively provided with first bending portions 111 facing the side where the shift block assembly 12 is located, and the positioning portion 13 is arranged on the first bending portion 111. The second mounting member 25 is provided with a second bending portion 252 on a side close to the sliding slot 211, a positioning slot 24 is arranged on the second bending portion 252, and another positioning slot 24 is arranged on a side of the mounting seat 21 away from the lock column 222 and located on a side away from the sliding slot 211.

[0061] Combination Figure 2 , Figure 4 and Figure 7a As shown, the second locking module 2 also includes a third mounting member 26 arranged on a side of the mounting seat 21 away from the second mounting member 25. The third mounting member 26 is provided with an opening 261 corresponding to the sliding groove 211. When the shift block assembly 12 is installed in the sliding groove 211, it is installed in the opening 261 and connected and cooperated with the third mounting member 26 for positioning installation.

[0062] In this embodiment, the sliding groove 211 on the mounting seat 21 can be set in a U-shape, and the bottom end of the sliding groove 211 serves as a locking position 2112. Of course, the sliding groove 211 can also be set in other shapes. The third mounting member 26 can be a U-shaped plate, and its opening 261 is set in a U-shape, and the opening 261 of the third mounting member 26 is narrower than the sliding groove 211, so that the third mounting member 26 extends into the inner side of the sliding groove 211 at the edge of the corresponding opening 261 to form a clamping portion 262. Correspondingly, the shaft portion 121 is correspondingly provided with a groove 1211, and the groove 1211 can be arranged on the circumference of the shaft portion 121. When the shift block assembly 12 is installed in the sliding groove 211, the shaft portion 121 installed in the opening 261 is clamped and connected with the clamping portion 262 of the third mounting member 26 through its groove 1211.

[0063] It can be understood that the third mounting member 26 plays a positioning role in the installation of the shift block assembly 12, so that after the shift block assembly 12 is installed and locked, the limiting structure plays a role in limiting and preventing rotation.

[0064] The shaft portion 121 can drive the third mounting member 26 to move synchronously when moving back and forth between the second mounting member 25 and the second mounting member 25. In this embodiment, the third mounting member 26 is mounted on the mounting seat 21 through the mounting shaft 232, and the mounting shaft 232 is provided with a second elastic member 233 on the side of the third mounting member 26 that is away from the mounting seat 21. The mounting shaft 232 can be a pin, and the second elastic member 233 can be a second spring. It can be understood that by providing the second elastic member 233, an elastic force is provided to the third mounting member 26 toward the mounting seat 21.

[0065] In this embodiment, it can be configured that when the second elastic member 233 is in a natural state, the shaft portion 121 is engaged with the third mounting member 26 through its groove 1211, the paddle 122 is limited by two limiting walls 251, the positioning portion 13 is inserted into the positioning groove 24, and the first locking module 1 is in a limited state. Figure 7a As shown, when the first locking module 1 is moved away from the second mounting member 25, the third mounting member 26 synchronously follows the movement of the shaft portion 121, the second elastic member 233 is compressed, the paddle 122 disengages from the two limiting walls 251, and the positioning portion 13 disengages from the positioning groove 24, thereby releasing the limit.

[0066] In this embodiment, when the locking tongue 221 of the second locking module 2 locks the shaft 121 of the first locking module 1, the first locking module 1 is pulled to move it away from the second mounting member 25 to release the limit, and then the first locking module 1 is rotated to release the obstruction of the locking tongue 221, so that the shaft 121 can be released from the locking position 2112, thereby achieving unlocking. Unlocking can only be achieved through the combined action of moving and rotating, so that the emergency communication equipment will not fall out during normal use and transportation, thereby improving reliability.

[0067] Furthermore, the sliding groove 211 further includes an entry position 2111 for the shift block assembly 12 to enter the sliding groove 211 , and the second locking module 2 further includes an unlocking assembly disposed near the entry position 2111 , and the unlocking assembly is used to lock or release the locking tongue assembly 22 .

[0068] Specifically, Figure 4 As shown, the sliding groove 211 passes through one end of the mounting seat 21 to form an entry position 2111, which facilitates the block assembly 12 to enter the sliding groove 211. The opening at the upper end of the sliding groove 211 serves as the entry position 2111, and the entry position 2111 and the locking position 2112 are respectively located at opposite ends of the sliding groove 211.

[0069] The unlocking assembly includes a locking spring piece. A matching structure is provided between the locking spring piece 27 and the lock tongue 221. When the lock tongue 221 moves to a preset position away from the sliding slot 211, the locking spring piece 27 locks the lock tongue 221 through the matching structure.

[0070] Specifically, combined Figure 4 , Figure 5As shown, the locking spring piece 27 can be arranged at the end of the lock tongue assembly 22 close to the entry position 2111, the locking spring piece 27 includes a fixed side 271 away from the sliding groove 211 and fixed on the mounting seat 21, and a movable side 272 close to the sliding groove 211, and the matching structure includes a hook portion 273 arranged between the fixed side 271 and the movable side 272 of the locking spring piece 27, and a notch portion 2212 correspondingly arranged on the lock tongue 221, and the mounting seat 21 is provided with a yielding groove 2113 at the corresponding hook portion 273. Among them, the notch portion 2212 is arranged at one end of the lock tongue 221 close to the locking spring piece 27, and the lock tongue 221 is arranged higher than the notch portion 2212 on the side of the notch portion 2212 away from the sliding groove 211, and the lock tongue 221 can be arranged flush on the side of the notch portion 2212 away from the sliding groove 211.

[0071] It can be understood that the preset position is a position where the locking tongue 221 moves away from the sliding groove 211 and does not hinder the shift block assembly 12 from escaping outwards. Figure 7c When the paddle 122 pushes the lock post 222 to move the lock tongue 221 away from the sliding slot 211, when the lock tongue 221 moves to the point where its notch 2212 corresponds to the hook 273 of the locking spring 27, the locking spring 27 falls down and locks the lock tongue 221 through the hook 273 and the notch 2212. Figure 7c As shown, the shift block assembly 12 can be smoothly disengaged.

[0072] Combination Figure 6b , Figure 7c As shown, in this embodiment, the preset position is larger than the position where the shaft portion 121 pushes the lock tongue 221 to move during the installation and locking process ( Figure 6b ) is arranged further away from the sliding groove 211, so that when the shaft portion 121 moves from the entry position 2111 to the locking position 2112, the locking tongue 221 will not be locked, which facilitates the locking tongue 221 to reset itself.

[0073] Combination Figure 4 , Figure 5 As shown, in order to achieve the reset of the lock tongue 221 after the unlocking is completed, the second locking module 2 also includes an unlocking structure 28, and the unlocking structure 28 can move toward the sliding groove 211 and away from the sliding groove 211; the unlocking structure 28 includes a side close to the sliding groove 211 and capable of extending into the sliding groove 211 and the other side close to the locking spring piece 27; when the unlocking structure 28 moves away from the sliding groove 211, it drives the locking spring piece 27 to move, so as to release the cooperation between the locking spring piece 27 and the lock tongue 221 and release the lock tongue 221.

[0074] The unlocking structure 28 is located on one side of the locking spring 27 close to the sliding slot 211, and the other side of the sliding slot 211 is close to the movable side 272 of the locking spring 27. The unlocking structure 28 may include a head 281 disposed close to the sliding slot 211 and an arm 282 disposed close to the locking spring 27.

[0075] The second locking module 2 further includes a third elastic member 234 that provides elastic force to the unlocking structure 28 toward the sliding slot 211. The third elastic member 234 may be a third spring, and is disposed on a side of the head 281 of the unlocking structure 28 away from the sliding slot 211. Figure 7d to Figure 7f As shown, it can be understood that when the shift block assembly 12 continues to move toward the entry position 2111, the shaft portion 121 pushes the unlocking structure 28, causing the unlocking structure 28 to move away from the sliding slot 211, and pushes the movable side 272 of the locking spring sheet 27, causing the locking spring sheet 27 to pop up toward the end of the entry position 2111, thereby releasing the lock tongue 221, and the lock tongue 221 is reset.

[0076] like Figure 4 As shown, in this embodiment, the mounting seat 21 is provided with corresponding structures for installing and moving the lock tongue 221, the locking spring piece 27, and the unlocking structure 28 on the side facing away from the third mounting member 26. The second locking module 2 also includes a baffle 29 detachably mounted on the side of the mounting seat 21 facing away from the third mounting member 26, and the lock tongue 221, the locking spring piece 27, and the unlocking structure 28 are fixed at the corresponding positions of the mounting seat 21 through the baffle 29. Among them, the baffle 29 is provided with a clearance opening 291 corresponding to the lock column 222 and for the lock column 222 to move.

[0077] It can be understood that the backpack and the mounting bracket of the emergency communication equipment are both provided with mounting structures, such as Figure 2 , Figure 4 As shown, the first mounting member 11 of the first locking module 1 and the second mounting member 25 of the second locking module 2 may be provided with mounting holes 4 respectively, so as to facilitate the installation of the first locking module 1 and the second locking module 2 on the emergency communication device and the backpack respectively. For example, the first locking module 1 and the second locking module 2 may be fixed on the emergency communication device and the backpack by screws.

[0078] like Figures 6a to 6cAs shown, the installation and locking process of the locking structure 10 of this embodiment is specifically as follows: after aligning the groove 1211 on the shaft portion 121 of the first locking module 1 with the engaging portion 262 of the third mounting member 26, slide from the entry position 2111 of the sliding groove 211 into the sliding groove 211 of the second locking module 2, and move toward the locking position 2112. During the movement, the shaft portion 121 pushes the locking tongue 221 to move back to the sliding groove 211, and the locking tongue 221 retracts and gives way. When the locking tongue 221 retracts to a certain position, the shaft portion 121 can be smoothly moved to the locking position 2112; the locking tongue 221 pops out into the sliding groove 211 under the push of the first elastic member 231, thereby realizing the locking of the shaft portion 121 of the first locking module 1.

[0079] Combination Figures 7a to 7f The overall disassembly and unlocking process of the locking structure 10 is as follows: Figure 7a As shown, the first locking module 1 is first pulled toward the side away from the second mounting member 25, so that the paddle 122 is disengaged from the two limiting walls 251, and the positioning portion 13 is disengaged from the positioning groove 24, thereby releasing the limiting position. Figure 7b , Figure 7c As shown, the first locking module 1 is rotated clockwise, the paddle 122 pushes the lock column 222 to move away from the sliding slot 211, and when the lock tongue 221 retracts to the set position, the locking spring 27 falls down, and the locking spring 27 cooperates with the notch of the lock tongue 221 through the hook portion 273 to lock the lock tongue 221. Figure 7d As shown, at this time, the first locking module 1 can be moved toward the entry position 2111; Figure 7e As shown, during the movement of the first locking module 1, the unlocking structure 28 is pushed to move back to the sliding slot 211, and the unlocking structure 28 pushes the locking spring 27, the locking spring 27 tilts up, and the hook portion 273 of the locking spring 27 leaves the notch portion 2212 of the lock tongue 221, thereby releasing the restriction on the lock tongue 221; Figure 7f As shown, the locking tongue 221 is pushed by the first elastic member 231 to pop out toward the sliding groove 211 to complete the reset.

[0080] The locking structure 10 of the utility model has locking and unlocking functions. In emergency use scenarios, the emergency communication equipment can be quickly assembled and disassembled, which greatly improves the response speed; and the lock tongue 221, the unlocking structure 28, and the third mounting member 26 can be automatically reset to ensure that they can be repeatedly assembled and disassembled; and the unlocking process requires first releasing the limit and then rotating to achieve unlocking, that is, the unlocking process requires a combined action to unlock, so that the emergency communication equipment will not fall out during transportation and normal use, and the reliability is strong.

[0081] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model.
