Description

Technical Field

[0001] This utility model relates to a zipper latch, and more particularly to a zipper latch adapted to a universal zipper tab. Background Technology

[0002] There is a type of zipper pull lock on the market that attaches upside down to the zipper strap of a bag, thus hiding the zipper head inside the lock body to achieve the purpose of theft prevention. For example, the patent with announcement number CN204060178U, entitled "A Composite Mechanical Lock", is like this. In this application, the fixing post on the lock seat is used to fix the zipper piece. However, this method usually requires a specially made zipper piece for this fixing post, which makes the zipper pull lock not versatile enough. Other zipper locks on the market use a universal zipper head with an L-shaped structure. How to match the universal L-shaped zipper piece with the zipper pull lock is the technical problem we need to solve now. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a zipper latch.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a zipper latch, characterized in that it includes a latch seat and a fixed seat respectively installed on the box body and positioned relative to both sides of the zipper chain. The top of the latch seat is provided with a lock groove for the zipper hook to be inserted. It includes a housing that rotatably engages with the fixed seat and is equipped with a combination lock component. The combination lock component includes a lock block for locking and unlocking the latch seat. The latch seat is provided with a lock hole that engages with the lock block. The housing is provided with a pusher that engages with the lock block and slides with the housing. The bottom of the housing is provided with a groove for accommodating the latch seat and the zipper. The zipper is limited in the groove by rotating the housing on the fixed seat and fastening it on the latch seat.

[0005] The pusher has a U-shaped cross section, and a groove for accommodating the pusher is provided in the middle of the top surface of the shell. The pusher achieves reciprocating motion on the shell through the cooperation of the groove.

[0006] The bottom of the pusher is provided with a connecting block that matches the locking block. The groove is provided with a through groove for the connecting block. The bottom of the connecting block is connected to a connecting rod. The other end of the connecting rod is linked to the locking block. The pusher is driven by the locking block through the cooperation between the connecting block and the connecting rod.

[0007] The connecting rod is provided with a protrusion for linkage and pushing, and the connecting block is provided with a limiting hole that matches the protrusion. The connecting rod and the pusher are linked by inserting the protrusion into the limiting hole.

[0008] Both the protrusion and the limiting hole have circular cross-sections, and the connecting rod is rotatably connected to the push rod with the axial direction of the protrusion as the rotation axis.

[0009] The connecting rod is provided with an inclined surface that forces the locking block to reciprocate. The locking block is provided with a groove for the connecting rod to reciprocate. The groove is provided with a stop part that matches the inclined surface. The connecting rod realizes the reciprocating motion of the locking block through the cooperation of the inclined surface and the stop part.

[0010] The lock block is provided with a protrusion that matches the lock hole. The lock hole has a moving space for the protrusion to move. The housing and the lock seat are relatively displaced through the cooperation of the protrusion and the moving space. The housing and the lock seat can move towards each other and away from each other through the relative displacement.

[0011] The housing is equipped with an elastic device that forces the lock block into the lock hole.

[0012] The password assembly includes a password wheel and a mating wheel that rotate with the housing. The password wheel and the mating wheel are linked together. The housing has an axle for mounting the mating wheel and a locking plate that prevents pushing motion. The locking plate is movably connected to the housing and has a swing angle. The mating wheel has a slot, and the locking plate has a protrusion that engages with the slot. When the password is correct, the locking plate engages with the slot through the protrusion and avoids pushing motion to unlock the device.

[0013] One side of the lock plate is provided with a lock cylinder, and the lock cylinder is provided with a rotating block that is linked and cooperates with the lock cylinder. When the rotating block rotates with the lock cylinder, the rotating block forces the lock plate to avoid the push by moving the lock plate, thereby unlocking the lock plate.

[0014] The beneficial effects of this utility model are as follows: This utility model sets a locking groove on the locking seat that can hold a universal zipper piece, which eliminates the lock body structure of the market that requires a special zipper piece, increases the universality of the entire lock body, and makes the zipper pieces of bag zipper locks usable in the lock body of this application. This utility model also has the characteristics of simple structure, convenient processing and easy assembly, and strong practicality. Attached Figure Description

Detailed Implementation

[0030] like Figures 1-14As shown, a zipper lock includes a lock seat 100 and a fixing seat 200 respectively mounted on the box body and positioned opposite to both sides of the zipper belt. The top of the lock seat 100 has a lock groove 110 for the locking hook 310 of the zipper piece 300 to be inserted. The lock also includes a housing 500 that rotatably engages with the fixing seat 200 and houses a combination lock component 400. The combination lock component 400 includes a locking block 410 for locking and unlocking the lock seat 100. The lock seat 100 has a lock hole 1 that engages with the locking block 410. 20. The housing 500 is provided with a pusher 510 that cooperates with the locking block 410 and slides with the housing 500. The bottom of the housing 500 is provided with a groove 520 for accommodating the lock seat 100 and the zipper piece 300. The zipper piece 300 is limited in the groove 520 by the rotation of the housing 500 on the fixed seat 200 and by the locking seat 100. The fixed seat 200 is designed as a groove structure, which can be inserted into the locking hook 310 part of the zipper piece 300, increasing the versatility of the lock body.

[0031] The pusher 510 has a U-shaped cross-section. The top surface of the housing 500 has a groove 530 for accommodating the pusher 510. The pusher 510 achieves reciprocating motion on the housing 500 through the cooperation of the groove 530. The pusher 510 is preferably located in the middle of the housing 500 because the length of the general zipper piece 300 is relatively long. If the pusher 510 is located at the position of the latch seat 100 as in the case of CN204060178U, the length and volume of the lock body will be larger, the volume ratio will be uncoordinated and unsightly, and the cost will be higher. Therefore, setting the pusher 510 in the middle can reduce the volume of the lock body and improve its practicality.

[0032] The bottom of the pusher 510 is provided with a connecting block 511 that matches the locking block 410. The groove 530 is provided with a through groove 531 that matches the connecting block 511. The bottom of the connecting block 511 is connected to a connecting rod 540. The other end of the connecting rod 540 is linked to the locking block 410. The pusher 510 is driven to the locking block 410 through the cooperation of the connecting block 511 and the connecting rod 540. The connecting rod 540 plays a transmission role in this process.

[0033] The connecting rod 540 is provided with a protrusion 541 for linkage with the pusher 510, and the connecting block 511 is provided with a limiting hole 512 that matches the protrusion 541. The connecting rod 540 and the pusher 510 are linked by inserting the protrusion 541 into the limiting hole 512.

[0034] Both the protrusion 541 and the limiting hole 512 have circular cross-sections. The connecting rod 540 is rotatably connected to the push rod 510 with the axial direction of the protrusion 541 as the rotation axis. The housing 500 is provided with a guide groove 550 for the reciprocating motion of the connecting rod 540. Setting the cross-sections of the protrusion 541 and the limiting hole 512 to be circular allows the connecting rod 540 and the push rod 510 to rotate. Since the connecting rod 540 is relatively small, assembly is slightly troublesome. Allowing them to rotate between each other can increase assembly efficiency. During installation, first install the push rod 510 onto the housing 500, then turn the housing 500 over. For easier installation, the connecting rod 540 can be perpendicular to the housing 500. Insert the protrusion 541 of the connecting rod 540 into the limiting hole 512 of the push rod 510, and then rotate the connecting rod 540 into the guide groove 550. This greatly improves the installation efficiency of the connecting rod 540 and makes it highly practical.

[0035] The connecting rod 540 is provided with an inclined surface 542 that forces the locking block 410 to reciprocate. The locking block 410 is provided with a groove 411 for the connecting rod 540 to reciprocate. The groove 411 is provided with a stop part 412 that cooperates with the inclined surface 542. The connecting rod 540 realizes the reciprocating motion of the locking block 410 through the cooperation of the inclined surface 542 and the stop part 412. The connecting rod 540 and the locking block 410 are basically perpendicular to each other. The connecting rod 540 causes the locking block 410 to reciprocate through the inclined surface 542.

[0036] The lock block 410 is provided with a protrusion 413 that mates with the lock hole 120. The lock hole 120 has a moving space for the protrusion 413 to move. The housing 500 and the lock seat 100 are relatively displaced through the cooperation of the protrusion 413 and the moving space. The housing 500 and the lock seat 100 can move towards each other and away from each other through the relative displacement. The main reason for adding the moving space is that the bag will expand as things are stuffed in. Without the moving space, the lock body can be easily damaged as the bag expands. With the addition of the moving space, the relative distance between the fixed seat 200 and the lock seat 100 will increase as the bag expands. The housing 500 moves away from the lock seat 100 along with the fixed seat 200, protecting the lock body and making it highly practical.

[0037] The housing 500 is provided with an elastic device 414 that forces the locking block 410 into the locking hole 120. The elastic device 414 is preferably a spring structure, which is easy to install and has low cost.

[0038] The password assembly 400 includes a password wheel 420 and a mating wheel 430 that rotatably engage with the housing 500. The password wheel 420 and the mating wheel 430 are linked together. The housing 500 has an axle 440 for mounting the mating wheel 430. The housing 500 also has a locking plate 450 that prevents the pusher 510 from moving. The locking plate 450 is movably connected to the housing 500 and has a swing angle. The mating wheel 430 and the locking plate 450 both have a locking groove 431. When the password is correct, the lock plate 450 is engaged in the slot 431 through the protrusion 451 and avoids the pusher 510 to unlock. The cooperation structure of this part can be found in the publication number CN212837222U, named "A linkage lock body with lock cylinder 600". The engagement wheel 430 is provided with a protrusion, and the password wheel 420 is provided with a cooperation groove for the cooperation protrusion. The engagement wheel 430 and the password wheel 420 are linked by the protrusion 432 engaging in the cooperation groove 421.

[0039] A lock cylinder 600 is provided on one side of the lock plate 450. A rotating block 610 is provided on the lock cylinder 600 in conjunction with the lock cylinder 600. When the rotating block 610 rotates with the lock cylinder 600, the rotating block 610 pushes the lock plate 450 to avoid the pusher 510 to achieve unlocking. The addition of the lock cylinder 600 improves practicality. When the correct key is inserted and turned, both the rotating block 610 and the lock cylinder 600 will rotate. The rotating block 610 causes the lock block 410 to swing on the other side of the lock block 410 relative to the wheel axle 440. The lock block 410 also moves away from the pusher 510 to achieve the purpose of unlocking.
