Description

Technical Field

[0001] This utility model belongs to the field of lock technology, specifically relating to a luggage lock installation structure. Background Technology

[0002] Luggage typically features zippers and locks. A zipper consists of two chain straps with teeth and a zipper pull that slides along the straps to engage or disengage the teeth. The zipper pull has a pull tab. The lock includes a lock body fixed to the bag and located on one side of the chain strap. To lock the bag, the user must first pull the zipper pull along the chain strap to the lock position, then adjust the pull tab towards the lock to engage it with the lock body. This lock design requires a separate mounting position on the side of the bag, which is inconvenient for bag manufacturing and makes the locking operation cumbersome.

[0003] In related technologies, a bag lock includes a lock body and a zipper head mounted on the lock body. The lock body is used in conjunction with the zipper head. The bag lock slides the lock body onto the zipper belt of the bag using the zipper head, and then locks the bag by cooperating with the zipper head. It features convenient installation, easy processing, and easy locking.

[0004] However, since the zipper pull is slidably connected to the bag's chain, the zipper pull can easily detach from the chain, thus affecting the locking mechanism and the bag's security. Utility Model Content

[0005] The purpose of this utility model is to disclose a luggage lock installation structure that can stably install luggage locks to ensure the locking effect and safety of luggage, and has the characteristics of convenient installation, easy processing and easy locking.

[0006] To achieve the above objectives, this utility model discloses a luggage lock mounting structure, comprising: The box shell includes a first box shell, a second box shell, and a chain structure.

[0025] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0026] Please see Figure 1 As shown in the figure, this application provides a luggage lock mounting structure, including a luggage shell 1. The luggage shell 1 includes a first luggage shell 11, a second luggage shell 12, and a chain structure. The first luggage shell 11 and the second luggage shell 12 are connected by the chain structure. The chain structure includes two chain straps, which are respectively fixed to the corresponding connection points of the first luggage shell 11 and the second luggage shell 12. The two chain straps are provided with teeth facing each other, and the teeth of the two chain straps engage or disengage to realize the closing or opening of the first luggage shell 11 and the second luggage shell 12.

[0027] In addition to the chain structure, corresponding ends of the first housing 11 and the second housing 12 can also be connected by hinges or other hinge structures. The first housing 11 and the second housing 12 are connected by hinges. The first housing 11 and the second housing 12 can be rotated to close or rotated to open based on the hinge structure. When the first housing 11 and the second housing 12 are rotated to close, the corresponding circumferences of the first housing 11 and the second housing 12 are connected by the meshing of the chain structure.

[0028] In the chain conveyor structure, the engagement or disengagement of the two chain straps is achieved through zipper heads 3. Two zipper heads 3 are provided, slidably disposed within the chain conveyor structure to close or open the first case 11 and the second case 12. The two zipper heads 3 slide back and forth along the extension direction of the two chain straps, causing the chain teeth of the two chain straps to engage or disengage accordingly, thereby closing or opening the first case 11 and the second case 12. When the two zipper heads 3 have slid into position to fully close the first case 11 and the second case 12, to ensure the safety of the bag and prevent loss of items or property inside, the two zipper heads 3 are locked by a lock body 2.

[0029] The lock body 2 is fixed to the case 1 and is located at the connection between the first case 11 and the second case 12. The chain structure is located at both axial ends of the lock body 2, and two zipper heads 3 are slidably disposed at both axial ends of the lock body 2. It should be noted that the axial direction of the lock body 2 is the sliding direction of the zipper heads 3 near the lock body 2. The lock body 2 is fixed at the connection between the first case 11 and the second case 12, eliminating the need to separately set up a mounting position for the lock body 2 on the main body of the first case 11 or the second case 12, which facilitates the processing of the case 1 and the installation of the lock body 2.

[0030] The zipper head 3 and the chain strap structure are both located at the axial ends of the lock body 2. The zipper head 3 slides from the hinge structure to the lock body 2, so that the teeth of the two chain straps mesh, closing the first case 11 and the second case 12. The lock body 2 locks the zipper head 3, preventing the case 1 from opening and ensuring the safety of the items and property inside the bag. When the lock body 2 releases the lock on the zipper head 3, the zipper head 3 slides away from the lock body 2, disengaging the teeth of the two chain straps and opening the first case 11 and the second case 12. When it is necessary to lock the zipper head 3, the zipper head 3 slides along the sliding track to the lock body 2, where it is locked. The position of the zipper head 3 components cannot be adjusted, making the locking operation simple. Furthermore, throughout the entire locking, unlocking, and opening / closing process of the case 1, the lock body 2 remains fixed and does not move relative to its installation position, ensuring stable installation and guaranteeing the locking effect and security of the bag. The zipper head 3 and the chain structure are located at the axial end of the lock body 2. As long as the zipper head 3 can correspond to a certain part of the axial end of the lock body 2, the lock body 2 can be centrally located between the first housing 11 and the second housing 12, or located near the first housing 11, or located near the second housing 12.

[0031] In this embodiment, the central axes of the chain conveyor structure, zipper head 3, and lock body 2 are aligned. The chain conveyor structure, zipper head 3, and lock body 2 are all centrally located between the first case shell 11 and the second case shell 12, and their central axes coincide. This ensures that the zipper head 3 can slide stably and smoothly on the chain conveyor structure, and that the lock body 2 can quickly lock the zipper head 3 when it slides to the axial end of the lock body 2. After the lock body 2 locks the zipper head 3, forcibly pulling the zipper head 3 will apply force along the central axis direction, without any force in other directions. This makes it less likely to compromise the locking stability of the lock body 2, ensuring the locking effect of the lock body 2 on the zipper head 3 and guaranteeing the security of the bag.

[0032] See Figure 2-3 The first housing 11 has a mounting groove 111 for the lock body 2 at the corresponding chain structure. The chain structure is located at both ends of the mounting groove 111. When the housing 1 is closed, the end of the mounting groove 111 facing away from the first housing 11 is connected to the second housing 12, and the lock body 2 is fixed to the mounting groove 111. The mounting groove 111 is used to fix and accommodate the lock body 2. The lock body 2 is fixed to the mounting groove 111 by screws, adhesives, buckles, or other structures to ensure the stable installation of the lock body 2. The position of the mounting groove 111 needs to ensure that after the lock body 2 is installed, the locking structure of the lock body 2 and the zipper head 3 can be on the same plane so that the lock body 2 can stably lock the zipper head 3.

[0033] The mounting groove 111 is located at the location of the chain structure corresponding to the first housing 11. It can be flush with the chain structure, or recessed inward relative to the chain structure towards the first housing 11, or protruding outward relative to the chain structure towards the second housing 12. As long as the locking structure at the axial end of the lock body 2 can lock with the zipper head 3, and the first housing 11 and the second housing 12 can be tightly connected when they are closed.

[0034] Since the central axes of the chain structure, zipper head 3, and lock body 2 are aligned, it is beneficial to improve the locking effect of the lock body 2 on the zipper head 3. Therefore, the central axis of the mounting groove 111 is preferably aligned with the central axis of the zipper head 3. That is, the mounting groove 111 protrudes towards the second housing 12, and the second housing 12 has a corresponding clearance 121. The mounting groove 111 protrudes towards the first housing 11 by the same amount as it protrudes towards the second housing 12. The mounting groove 111 is centrally located between the first housing 11 and the second housing 12. Since the mounting groove 111 is fixed to the first housing 11 by screws, adhesives, snap-fits, or other structures, the second housing 12 has a clearance 121 to allow the mounting groove 111 to protrude towards the second housing 12.

[0035] The bottom of the clearance position 121 may be provided with an extension facing the first housing 11. When the first housing 11 and the second housing 12 are closed, the extension is located at the bottom of the mounting groove 111, which helps to improve the tightness of the first housing 11 and the second housing 12.

[0036] The zipper head 3 is provided with a pull tab 31 and a locking tab 32. The pull tab 31 is used to pull the zipper head 3 to slide along the chain structure. The locking tab 32 is disposed facing the axial end of the lock body 2. The axial end of the lock body 2 is provided with a locking hook structure 21. The locking hook structure 21 rotates to lock or unlock the locking tab 32. The pull tab 31 is rotatably disposed on the zipper head 3 to pull the zipper head 3 to slide back and forth along the chain structure, thereby realizing the closing or opening of the first box shell 11 and the second box shell 12. The locking tab 32 is disposed facing the lock body 2. When the zipper head 3 slides to the axial end of the lock body 2, the locking tab 32 is disposed corresponding to the locking hook structure 21 to lock the locking tab 32. The locking hook structure 21 can be disposed inside the lock body 2 or outside the axial end of the lock body 2, as long as it can lock with the locking tab 32.

[0037] In this embodiment, refer to Figure 4-6 and Figure 9 The lock body 2 includes a lock shell 22, which contains a lock hook structure 21, a locking assembly, a lock block structure 23, and a movable piece 24. The locking assembly is used to lock or unlock the axial movement of the movable piece 24, so as to lock or unlock the rotation of the lock hook structure 21 through the lock block structure 23. A connection port 221 is provided at the axial end of the lock shell 22, and the lock piece 32 is locked or unlocked to the lock hook structure 21 through the connection port 221.

[0038] The lock housing 22 includes a face shell 222 and a cover plate 223 that overlap each other. The face shell 222 and the cover plate 223 are detachably connected by screws, clips, or other structures to facilitate replacement, maintenance, or operation of internal components. The face shell 222 is fastened onto the cover plate 223 to form an accommodating space between them. The locking hook structure 21, locking assembly, locking block structure 23, and movable piece 24 are all located in the accommodating space. The locking hook structure 21 is located at both axial ends of the accommodating space. The two axial ends of the face shell 222 have connection ports 221 corresponding to the locking hook structure 21. The locking piece 32 extends into the accommodating space through the connection ports 221 to be locked by the locking hook structure 21.

[0039] The locking component has locking and unlocking functions. When the locking component is locked, the movable piece 24 is locked and cannot move axially, thereby locking the locking block structure 23. The locking block structure 23 locks the locking hook structure 21 so that it cannot rotate. At this time, the locking hook structure 21 locks the locking piece 32 to achieve the locking of the lock body 2 onto the zipper head 3. When the locking component is unlocked, it can drive the movable piece 24 to move axially, thereby driving the locking block structure 23 to move and release the locking hook structure 21. The locking hook structure 21 can rotate, thereby pulling the pull tab 31 to unlock the locking piece 32 of the zipper head 3 from the locking hook structure 21, thereby unlocking the zipper head 3 so that the zipper head 3 can slide along the chain structure.

[0040] See Figure 5-9 The locking assembly includes a combination wheel structure 25 and a clutch structure 26. The clutch structure 26 includes a clutch block 261 that is pulsatorically connected to the movable plate 24. The combination wheel structure 25 is used to lock or unlock the clutch block 261 to lock or unlock the axial movement of the movable plate 24. An elastic reset member 27 is provided between the movable plate 24 and the lock housing 22. The movable plate 24 moves axially to compress the elastic reset member 27.

[0041] The combination wheel structure 25 has locking and unlocking functions. When the combination wheel structure 25 is locked, the clutch block 261 is locked and cannot move, thereby restricting the axial movement of the movable piece 24, so that the lock block structure 23 locks the lock hook structure 21. The lock hook structure 21 cannot rotate, thereby locking the lock body 2 onto the zipper head 3. At this time, the elastic reset member 27 is in a naturally extended state. When the combination is correct, the combination wheel structure 25 is unlocked, the clutch block 261 can move and drive the movable piece 24 to move axially, thereby driving the lock block structure 23 to move and release the lock hook structure 21. The lock hook structure 21 can rotate, thereby pulling the pull piece 31 to unlock the lock piece 32 of the zipper head 3 from the lock hook structure 21, thereby unlocking the zipper head 3, so that the zipper head 3 can slide along the chain structure. At this time, the elastic reset member 27 is in a compressed state. Once unlocking is complete, if there is no external force restricting it, the movable piece 24 will move axially in the opposite direction to reset under the elastic force of the elastic reset piece 27, and drive the clutch block 261 and the locking block structure 23 to reset, and the locking block structure 23 will relock the hook structure 21.

[0042] The elastic reset member 27 is provided on the cover plate 223. One end of the elastic reset member 27 is fixed to the cover plate 223, and the other end of the elastic reset member 27 is fixed to the movable piece 24. When the movable piece 24 moves axially to unlock, the elastic reset member 27 is compressed so as to facilitate the subsequent elastic force-assisted reset of the elastic reset member 27.

[0043] The combination wheel structure 25 includes a wheel axle 251, a combination wheel set 252, and a reset member 253. The combination wheel set 252 is rotatably sleeved on the wheel axle 251. The reset member 253 is located between one axial end of the wheel axle 251 and the combination wheel set 252. In the locked state, the reset member 253 is in a naturally extended state. In the unlocked state, the wheel axle 251 can compress the reset member 253 and move axially. The clutch structure 26 includes a drive member 262 and a lock cylinder 263. The drive member 262 is connected to a clutch block 261 via the lock cylinder 263. The clutch block 261 abuts against the end of the wheel axle 251 facing away from the reset member 253. In the unlocked state, the drive member 262 drives the clutch block 261, the wheel axle 251, and the movable piece 24 to move axially synchronously via the lock cylinder 263.

[0044] The clutch block 261 abuts against the end of the axle 251 where the reset member 253 is located. When the password is incorrect, the password wheel set 252 restricts the axial movement of the axle 251. At this time, the reset member 253 is in a naturally extended state like a spring. When the password is correct, the password wheel set 252 releases the restriction on the axial movement of the axle 251. The drive member 262 drives the clutch block 261 via the lock cylinder 263. The clutch block 261 can push the axle 251 axially toward the password wheel set 252 and compress the reset member 253. Thus, the clutch block 261 can drive the movable piece 24 to move axially synchronously, thereby driving the lock block structure 23 to move and release the lock hook structure 21. The lock hook structure 21 can rotate, thereby pulling the pull tab 31 to unlock the lock piece 32 of the zipper head 3 from the lock hook structure 21, realizing the unlocking of the zipper head 3, so that the zipper head 3 can slide along the chain structure.

[0045] The movable piece 24 has a receiving groove 241 corresponding to the clutch block 261. The bottom of the clutch block 261 is fixed to the receiving groove 241. The side of the clutch block 261 away from the wheel axle 251 has an inclined surface. The lock cylinder 263 is provided on the clutch block 261 corresponding to the inclined surface. The driving component 262 is provided on the lock cylinder 263. The driving component 262 can be a button, knob, push block, etc. In this embodiment, a button is used as an example. The button and the combination wheel 252 are both inserted into the miniature 222. When the combination is correct, the button is pressed down to make the lock cylinder 263 move downward to push the clutch block 261 against the wheel axle 251, thereby performing the unlocking operation.

[0046] The locking hook structure 21 includes a locking hook 211, a rotating shaft 212, and a torsion spring 213. The rotating shaft 212 is located at the rotation axis of the locking hook 211. The rotating shaft 212 and the locking hook 211 are connected by the torsion spring 213. The locking hook 211 is provided with a limiting block 2111 facing the locking block structure 23. The locking block structure 23 includes a locking block 231. The locking block 231 is provided with a limiting groove 2311 corresponding to the limiting block 2111. The movable piece 24 is provided with an axially inclined sliding groove 242. The movable piece 24 moves axially to drive the locking block 231 to slide along the sliding groove 242, so that the limiting groove 2311 moves closer to or away from the limiting block 2111.

[0047] The locking block 231 is equipped with a connecting shaft. When locked, the connecting shaft is located at the end of the slide groove 242 near the clutch structure 26. At this time, the limiting block 2111 and the limiting groove 2311 are misaligned, and the limiting block 2111 abuts against the bottom of the locking block 231 to lock the lock hook 211. When the password is correct, the axial movement of the movable piece 24 can drive the locking block 231 to slide laterally, so that the connecting shaft is located at the end of the slide groove 242 away from the clutch structure 26. At this time, the limiting block 2111 and the limiting groove 2311 are correspondingly set. Pulling the zipper head 3 can rotate the lock hook 211 to unlock.

[0048] The lock hook 211 rotates around the pivot 212. After the lock hook 211 is unlocked by rotation, it is reset by the elastic assistance of the torsion spring 213.

[0049] The locking block structure 23 includes a top block 232 and an elastic element 233. The top block 232 is vertically positioned between the locking block 231 and the lock housing 22. The elastic element 233 is positioned between the top block 232 and the lock housing 22. The locking block 231 slides to move the top block 232 closer to or further away from the limiting groove 2311, and to extend or compress the elastic element 233. In the locked state, the elastic element 233 is compressed between the face shell 222 and the top block 232, with the top block 232 abutting against the top of the locking block 231. During unlocking, the lateral sliding of the locking block 231 causes the top block 232 to align with the limiting groove 2311. The elastic force of the elastic element 233 lifts the top block 232 into the limiting groove 2311, preventing the repositioning of the movable piece 24, the locking block 231, etc., from affecting the manual pulling out of the zipper head 3.

[0050] Based on this, the working principle of the bag lock of this utility model is as follows: When the password is incorrect, the password wheel assembly 252 restricts the axial movement of the wheel axle 251. At this time, the reset member 253 is in a naturally extended state, and the clutch structure 26, the movable piece 24, the locking block structure 23 and the locking hook structure 21 are all in a locked state. The locking hook 211 cannot be rotated, and the zipper head 3 cannot be pulled out from the locking hook 211.

[0051] When the password is correct, the password wheel assembly 252 releases the restriction on the axial movement of the wheel axle 251. Pressing the button causes the lock cylinder 263 to move downward, pushing the clutch block 261 against the wheel axle 251 and moving axially toward the password wheel assembly 252, thus compressing the reset member 253. As a result, the clutch block 261 can drive the movable piece 24 to move axially synchronously, and use the slide groove to drive the lock block 231 to slide laterally to the limit groove 2311, corresponding to the limit block 2111 and the top block 232. The elastic force of the elastic member 233 bounces the top block 232 into the limit groove 2311 to prevent the wheel axle 251, clutch structure 26 and movable piece 24 from resetting under the elastic force of the elastic reset member 27, reset member 253, etc., and to drive the lock block 231 to reset. Pulling the pull tab 31 causes the locking hook 211 to rotate, pulling out the zipper head 3. At this time, the limiting block 2111 of the locking hook 211 rotates into the limiting groove 2311, pushing the top block 232 out of the limiting groove 2311 and compressing the elastic member 233. At this time, under the elastic force of the elastic reset member 27, reset member 253, etc., the locking block 231 resets about half a distance. The limiting block 2111 abuts against the side wall of the limiting groove 2311 that has reset and moved. The locking block 231 abuts against the top block 232 to prevent it from springing up again.

[0052] When the lock plate 32 is reinserted into the lock hook 211, the lock plate 32 rotates against the lock hook 211 until the limit block 2111 disengages from the limit groove 2311, thereby releasing the limitation of the limit block 2111 on the reset of the lock block 231, so that the combination wheel structure 25, the movable plate 24, the lock block structure 23, and the clutch structure 26 are reset and locked.
