Description

Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to a zipper lock with a connecting buckle. Background Technology

[0002] Zippers are common items in daily life, used in suitcases, backpacks, school bags, handbags, portable tents, and portable mosquito nets. Most of them do not have locking mechanisms, which means that mischievous classmates, colleagues, strangers, naughty children, competitors, thieves, or people you don't like can easily rummage through your suitcases, backpacks, school bags, and handbags without your consent. This can lead to theft or damage of personal belongings or important documents, malicious alteration or exposure of your privacy, and other problems.

[0003] Chinese patent CN222909707U discloses a zipper lock with a connecting buckle, which directly locks to the hole of the movable part of the zipper head, thereby achieving the purpose of locking the zipper head. However, some holes of the movable parts of zipper heads are too small or mismatched in size, so the zipper lock with the connecting buckle cannot be connected to zipper heads of these sizes, and therefore cannot meet the current production needs.

[0004] To solve the above problems, it is necessary to provide a zipper lock with a connecting buckle. Utility Model Content

[0005] The purpose of this invention is to provide a zipper lock with a connecting buckle that is simple in structure, low in cost, and adaptable to zipper heads of multiple sizes.

[0006] To achieve the above objectives, the zipper lock with a connecting buckle provided by this utility model includes a lock head plate, a lock, and a connecting buckle. The lock head plate is connected to the bottom of the lock and is used to lock the zipper. The connecting buckle is used to detachably connect to the fixing handle of the zipper head. The lock is used to lock the connecting buckle, and the locking of the lock and the connecting buckle causes the lock to lock the fixing handle of the zipper head.

[0007] Preferably, the connecting buckle has a locking hole, and the lock is connected to the connecting buckle through the locking hole.

[0008] Specifically, the fastener includes a fastener body, a retaining ring, and a first locking member. The retaining ring has an opening structure into which the fixing handle of the zipper head extends. The fastener body has a blocking part corresponding to the opening structure. The fastener body is connected to the retaining ring through the first locking member, so that the blocking part blocks the opening of the opening structure and closes the opening structure. The fastener body extends outward to form an extension part, and the locking hole is opened in the extension part.

[0009] Specifically, the retaining ring has a connecting hole, and the connecting buckle body has a locking groove corresponding to the connecting hole. The first locking member passes through the connecting hole and connects with the locking groove so that the connecting buckle body is connected to the retaining ring.

[0010] Preferably, the lock clamp includes an upper connector, a lower pressure plate, and a second locking member. The upper connector is connected to the bottom of the lock, and the lower pressure plate is located below the upper connector, so that a clamping space for accommodating the zipper is formed between the upper connector and the lower pressure plate. The second locking member locks the relative position between the upper connector and the lower pressure plate so that the upper connector and the lower pressure plate together clamp the zipper.

[0011] Specifically, the upper connector is provided with a threaded hole, and the lower pressure plate is provided with a through hole corresponding to the threaded hole. The second locking member is a bolt. The threaded hole, the through hole and the second locking member are paired with each other. The second locking member is connected to the threaded hole through the through hole to lock the relative position between the upper connector and the lower pressure plate.

[0012] Preferably, the lock is an electronic lock, which includes a first housing, an electronic component, a drive mechanism, a first elastic element, and a first bolt. The first housing is connected to the lock head plate. The electronic component and the drive mechanism are both built into the first housing. The drive mechanism is electrically connected to the electronic component. The output end of the drive mechanism is connected to the first bolt. The first bolt has a locking position for locking the connecting buckle and a releasing position for releasing the connecting buckle. The first elastic element provides an elastic force that constantly causes the first bolt to tend to move from the releasing position to the locking position. Under the drive of the drive mechanism, the first bolt overcomes the elastic force of the first elastic element and moves from the locking position to the releasing position.

[0013] Specifically, the output end of the drive mechanism has a retractable abutment head, the first locking tongue is movably disposed on the first housing, and the first locking tongue is provided with a matching drive part corresponding to the abutment head. The extension and retraction of the abutment head abuts the matching drive part and drives the first locking tongue to move up and down. The abutment head has an arc surface, and the matching drive part has a matching arc surface corresponding to the arc surface.

[0014] Specifically, the driving mechanism is an electrically heated shrinkable wire.

[0015] Preferably, the lock is a combination lock, which includes a second housing, a sliding drive, a combination lock, a second bolt, a second elastic element, and a third elastic element. The second housing is connected to the lock head plate. The sliding drive is slidably disposed inside the second housing and has a first position and a second position. The combination lock is used to lock the sliding drive in the second position. The second elastic element is disposed on the sliding drive and provides an elastic force that causes the sliding drive to always have a tendency to move from the first position to the second position. The second bolt... The sliding drive member moves under the drive to have a locking position for locking the connecting buckle and a releasing position for releasing the connecting buckle. The third elastic member is provided on the second latch and provides an elastic force that causes the second latch to always have a tendency to move from the releasing position to the locking position. When the combination lock releases the sliding drive member, by pushing the sliding drive member from the second position to the first position, the sliding drive member overcomes the elastic force of the second elastic member and pushes the second latch to move from the locking position to the releasing position.

[0016] Compared with the prior art, the zipper lock with a connecting buckle provided by this utility model can be detachably connected to the fixing handle of the external zipper head by setting the connecting buckle. In this way, the lock can indirectly lock the zipper head by directly locking the connecting buckle.

[0025] To explain in detail the technical content, structural features, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0026] Please see Figures 1 to 8 This illustration demonstrates the specific structure of the zipper lock 100 with a connecting buckle according to this utility model. The zipper lock 100 with a connecting buckle includes a lock head clamp 1, a lock 2, and a connecting buckle 3. The lock head clamp 1 is connected to the bottom of the lock 2 and is used to lock the zipper 10. The connecting buckle 3 is used to detachably connect to the fixing handle 20 of the zipper head. The lock 2 is used to lock the connecting buckle 3. By locking the lock 2 and the connecting buckle 3, the lock 2 locks the fixing handle 20 of the zipper head. The connecting buckle 3 can be detachably connected to the fixing handle 20 of the external zipper head. In this way, the lock 2 can indirectly lock the zipper head by directly locking the connecting buckle 3. The lock 2 can also be adapted to zipper heads of different sizes, without being limited to connecting only to the movable handle of the zipper head. It has the advantages of simple structure, low cost, and strong applicability. More specifically, as follows:

[0027] Please see Figures 5 to 8The connecting buckle 3 has a locking hole 31, and the lock 2 is connected to the connecting buckle 3 through the locking hole 31. The connecting buckle 3 includes a connecting buckle body 32, a retaining ring 33, and a first locking member 34. The retaining ring 33 has an opening structure 331 into which the fixing handle 20 of the zipper head extends. The connecting buckle body 32 has a blocking part 321 corresponding to the opening structure 331. The connecting buckle body 32 is connected to the retaining ring 33 through the first locking member 34, so that the blocking part 321 blocks the opening of the opening structure 331 and closes the opening structure 331. When the opening structure 331 is closed, the blocking part 321 and the opening structure 331 are joined together to form a closed loop, which locks the fixing handle 20 of the zipper head. When the opening structure 331 is opened, the fixing handle 20 of the zipper head can freely enter and exit the opening structure 331. The connecting buckle body 32 extends outward to form an extension part 321, and the locking hole 31 is opened in the extension part 321. In other embodiments, the first locking member 34 can be removed, and the connection between the connecting buckle body 32 and the retaining ring 33 is achieved through an engaging structure, but this is not a limitation. In other embodiments, the connecting buckle 3 can also be a closed-loop ring mechanism. When it is necessary to connect with the zipper head, the opening at the fixing handle 20 of the zipper head is opened to achieve the connection between the two, so this is not a limitation.

[0028] Please see Figures 5 to 6 The retaining ring 33 has a connecting hole 332, and the connecting buckle body 32 has a locking groove 322 corresponding to the connecting hole 332. The first locking member 34 passes through the connecting hole 332 and connects with the locking groove 322, so that the connecting buckle body 32 and the retaining ring 33 are connected. The first locking member 34 is a bolt, and both the connecting hole 332 and the locking groove 322 have corresponding threaded holes 111.

[0029] Please see Figures 1 to 4 The lock clamp 1 includes an upper connector 11, a lower pressure plate 12, and a second locking member 13. The upper connector 11 is connected to the bottom of the lock 2, and the lower pressure plate 12 is located below the upper connector 11, so that a clamping space 14 for accommodating the zipper 10 is formed between the upper connector 11 and the lower pressure plate 12. The second locking member 13 locks the relative position between the upper connector 11 and the lower pressure plate 12, so that the upper connector 11 and the lower pressure plate 12 together clamp the zipper 10. It can be understood that, due to the provision of the second locking member 13, the adjustability of the second locking member 13 allows the spacing of the clamping space 14 to be adjusted, thus accommodating zippers 10 of different thicknesses and providing strong applicability. Specifically, the edge of the lower pressure plate 12 extends outward to form a pressing edge 15, and the pressing edge 15 has a wavy texture for anti-slip purposes.

[0030] Please see Figures 1 to 4The upper connector 11 has a threaded hole 111, and the lower pressure plate 12 has a through hole 121 corresponding to the threaded hole 111. The second locking member 13 is a bolt. The threaded hole 111, the through hole 121, and the second locking member 13 correspond to each other. The second locking member 13 is connected to the threaded hole 111 through the through hole 121 to lock the relative position between the upper connector 11 and the lower pressure plate 12. The upper connector 11 extends downward to the lower pressure plate 12 to form a mounting part, and the threaded hole 111 is provided on the upper connector 11.

[0031] Please see Figures 1 to 4 For example, the lock 2 can be an electronic lock 2a or a combination lock 2b. When the lock 2 is an electronic lock 2a, the electronic lock 2a includes a first housing 21, an electronic component 22, a drive mechanism 23, a first elastic element 24, and a first bolt 25. The first housing 21 is connected to the lock head plate 1. The electronic component 22 and the drive mechanism 23 are both built into the first housing 21. The drive mechanism 23 is electrically connected to the electronic component 22. The output end of the drive mechanism 23 is connected to the first bolt 25. The first bolt 25 has a locking position for locking the connecting buckle 3 and a releasing position for releasing the connecting buckle 3. The first elastic element 24 provides an elastic force that constantly makes the first bolt 25 tend to move from the releasing position to the locking position. Under the drive of the drive mechanism 23, the first bolt 25 overcomes the elastic force of the first elastic element 24 and moves from the locking position to the releasing position.

[0032] Please see Figures 1 to 4 The output end of the drive mechanism 23 has a retractable abutment head 231. The first latch 25 is movably mounted on the first housing 21. The first latch 25 has a drive part 251 corresponding to the abutment head 231. The extension and retraction of the abutment head 231 abuts against the drive part 251 and drives the first latch 25 to move up and down. The abutment head 231 has an arc surface 232, and the drive part 251 has a matching arc surface 2511 corresponding to the arc surface 232. The cooperation between the arc surface 232 and the matching arc surface 2511 can guide the movement of the latch. In this embodiment, the drive mechanism 23 is a motor. The motor is connected to the abutment head 231 through a linkage component. Since the motor achieves linear motion through conversion, it is well known to those skilled in the art and will not be described in detail here. In other embodiments, the drive mechanism 23 is an electrically conductive heat-shrinkable wire. The electrically conductive heat-shrinkable wire is a special conductive wire. When energized, the electrically conductive heat-shrinkable wire will shrink as a whole. The shrinkage drives the mechanical movement of the latch to achieve the purpose of unlocking and locking.

[0033] Please see Figures 1 to 4The electronic component 22 includes a touch panel (not shown), a charging port (not shown), a battery (not shown), and an indicator light (not shown). The battery is built into the first housing 21. The touch panel is electrically connected to the battery. The charging port is located in the housing and is electrically connected to the battery. The indicator light is located on the touch panel. The drive mechanism 23 is electrically connected to both the touch panel and the battery. In this example, the touch panel is a touch screen panel, on which a personal fingerprint or password can be pre-set. The operation of the drive mechanism 23 can be controlled by inputting the fingerprint or password.

[0034] Please see Figures 5 to 6 When the lock 2 is a combination lock 2b, the combination lock 2b includes a second housing 26, a sliding drive 27, a combination lock 28, a second bolt 29, a second elastic element 30, and a third elastic element 31. The second housing 26 is connected to the lock head plate 1. The sliding drive 27 is slidably disposed inside the second housing 26 and has a first position and a second position. The combination lock 28 is used to lock the sliding drive 27 in the second position. When the combination lock 28 is unlocked, the sliding drive 27 can freely switch between the first position and the second position. The second elastic element 30 is disposed on the sliding drive 27 and provides an elastic force that causes the sliding drive 27 to always move from the first position. The second latch 29 moves to the second position under the drive of the sliding drive member 27, having a locked position for locking the connecting latch 3 and an unlocked position for releasing the connecting latch 3. A third elastic member 31 is provided on the second latch 29, providing an elastic force that causes the second latch 29 to constantly tend to move from the unlocked position to the locked position. When the combination lock 28 unlocks the sliding drive member 27, by pushing the sliding drive member 27 from the second position to the first position (i.e., moving to the left), the sliding drive member 27 overcomes the elastic force of the second elastic member 30 and pushes against the second latch 29, overcoming the elastic force of the third elastic member 31, moving from the locked position to the unlocked position. When locked, the combination lock 28 locks the sliding drive member 27 in the second position. Under the action of the second elastic member 30, the sliding drive member 27 moves from the first position to the second position (i.e., moving to the right), and the second latch 29, no longer resisted by the sliding drive member 27, resets from the unlocked position to the locked position. The sliding drive component 27 has a stop slope 271, and the second locking tongue 29 is provided with a stop slope 291 corresponding to the stop slope.

[0035] Please refer to the following: Figures 1 to 8 The working process of the zipper lock 100 with connecting buckle of this utility model is as follows:

[0036] In use, the user simply pulls open the zipper 10 to be installed, places the zipper lock 100 with the connecting buckle at the end of the zipper 10, and uses the clamping between the upper connector 11 and the lower pressure plate 12 to clamp the two sides of the zipper 10. At this time, the zipper lock 100 with the connecting buckle of this utility model has been fixed on the zipper 10.

[0037] Open the connecting buckle 3 so that the fixing handle 20 of the zipper head can extend into the opening structure 331 of the retaining ring 33. The main body 32 of the connecting buckle is connected to the retaining ring 33 through the first locking member 34 so that the blocking part 321 blocks the opening of the opening structure 331 and closes the opening structure 331. When the opening structure 331 is closed, the blocking part 321 and the opening structure 331 are joined together to form a closed loop. This closed loop locks the fixing handle 20 of the zipper head. Taking the electronic lock 2a as an example, the drive mechanism 23 is activated by operating the touch panel or button. Under the drive of the drive mechanism 23, the first locking tongue 25 overcomes the elastic force of the first elastic member 24 and moves from the locked position to the unlocked position. The locking hole 31 of the connecting buckle 3 is inserted under the first locking tongue 25 of the electronic lock 2a. The drive mechanism 23 is activated by operating the touch panel or button. The push head 231 retracts. Under the action of the elastic force of the first elastic member 24, the first locking tongue 25 moves from the unlocked position to the locked position.

[0038] When unlocking, you can use your personal fingerprint or a pre-set password to operate the touch panel to activate the drive mechanism 23. The drive mechanism 23 will move the first locking tongue 25 from the locked position to the unlocked position, and the zipper head will be unlocked and can be moved freely.

[0039] By setting the connecting buckle 3, the connecting buckle 3 can be detachably connected to the fixing handle 20 of the external zipper head. In this way, the lock 2 can indirectly lock the zipper head by directly locking the connecting buckle 3. The lock 2 can also be adapted to zipper heads of different sizes, without being limited to connecting only to the movable handle of the zipper head. It has the advantages of simple structure, low cost and strong applicability.

[0040] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
