Description

Technical Field

[0001] This utility model relates to the field of zipper technology, and in particular to an anti-theft and explosion-proof zipper. Background Technology

[0002] As a core closure component in clothing, bags, and packaging, the function of zippers has been upgraded from "basic closure" to "safety protection". In scenarios such as luggage, dangerous goods packaging, and outdoor equipment, zippers must have the ability to "prevent unauthorized opening (anti-theft)" and "resist external impact / pressure (explosion-proof)" to avoid loss of property, leakage of dangerous goods, or damage to equipment due to zipper failure.

[0003] The zipper head is used to close the double rows of zipper teeth, making the two rows of zipper teeth interlock together, and the zipper head is locked to enhance the stability of the zipper head.

[0004] Most existing zippers are single-row designs, which can be easily opened with a sharp object, lacking a certain level of security and explosion-proof function. Furthermore, there is no structure to secure the zipper head after it is pulled to the end, lacking a locking function, making it easy for thieves to pull the zipper head. Therefore, a theft-proof and explosion-proof zipper is proposed. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figures 1-3 This is the first embodiment of the present invention, which provides an anti-theft and explosion-proof zipper, comprising:

[0031] Zipper head 1;

[0032] An explosion-proof mechanism 2 is symmetrically arranged inside the zipper head 1. The explosion-proof mechanism 2 includes a first cloth strip 201 and a second cloth strip 202 arranged inside the zipper head 1. A sandwich fabric 204 is installed on one side of the two first cloth strips 201 opposite to each other. A number of zipper teeth 203 adapted to the zipper head 1 are evenly distributed from top to bottom on one side of the first cloth strip 201 and the second cloth strip 202.

[0033] like Figure 2 As shown, in this embodiment, a protrusion 207 is installed on the top of the zipper teeth 203, and a groove adapted to the protrusion 207 is opened at the bottom of several zipper teeth 203. The protrusion 207 is movably engaged in the groove. Under the action of the zipper head 1, several zipper teeth 203 are aligned in an orderly manner, and the protrusion 207 is engaged in the groove at the bottom of the zipper teeth 203 on one side of the first fabric strip 201, which strengthens the connection strength between the second fabric strip 202 and the first fabric strip 201. The second fabric strip 202 and the first fabric strip 201 are both arranged in double layers, which further increases the stability of explosion protection.

[0034] like Figure 2 and Figure 3 As shown in this embodiment, symmetrically installed on both sides of the inner surface of the zipper head 1 are the separating teeth 206 adapted to the zipper teeth 203. A pendant 205 is movably provided on one side of the zipper head 1. One end of the separating teeth 206 is located on one side of the interlayer fabric 204. Under the action of the separating teeth 206, the two rows of second fabric strips 202 can be slightly separated, so that the zipper head 1 can be pulled more smoothly, and the zipper teeth 203 between the two second fabric strips 202 can be prevented from biting each other.

[0035] Furthermore, bring the bottoms of the double-row first fabric strips 201 and second fabric strips 202 together, and place the closer ends of them into the zipper head 1. Manually pull the pendant 205 along the installation direction of the second fabric strip 202. The pendant 205 drives the zipper head 1 to move. With the assistance of the two separating teeth 206, the zipper teeth 203 on the two second fabric strips 202 and the first fabric strip 201 are separated in an orderly manner. During the movement of the zipper head 1, several zipper teeth 203 on one side of the second fabric strip 202 and several zipper teeth 203 on one side of the first fabric strip 201 mesh with each other. At this time, the protrusions 207 on the zipper teeth 203 are stuck at the bottom of the corresponding zipper teeth 203 on the opposite side. Pull the zipper head 1 to the top of the first fabric strip 201 and the second fabric strip 202 to complete the connection of several zipper teeth 203.

[0036] Example 2

[0037] Reference Figure 4 and Figure 5This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The anti-theft mechanism 3 is set on the top of the first cloth strip 201. The anti-theft mechanism 3 includes a top plate 301 installed on the top of the two first cloth strips 201. A cross slider 302 is movably installed inside the top plate 301. A card plate 303 is set inside the cross slider 302. A plug block 307 adapted to the card plate 303 is installed on the top of the zipper head 1.

[0038] like Figure 4 and Figure 5 As shown, in this embodiment, the top plate 301 has a cross groove inside that is adapted to the cross slider 302. The cross slider 302 is slidably connected inside the cross groove. Both the cross slider 302 and the bottom of the top plate 301 have insertion holes adapted to the insertion block 307. The locking plate 303 is installed inside the insertion hole of the cross slider 302. The insertion block 307 is movably inserted into the insertion hole. Under the action of the cross groove of the top plate 301, the cross slider 302 can be moved along the installation direction of the top plate 301. Under the action of the locking plate 303, after the insertion block 307 is inserted into the cross slider 302, the insertion block 307 is fixed inside the cross slider 302 to prevent the zipper head 1 from moving downward after the first strip 201 and the second strip 202 are subjected to outward pulling force.

[0039] like Figure 5 As shown, in this embodiment, a spring 304 is installed on one side of the cross slider 302, and a push plate 305 is provided on the other side of the cross slider 302. A baffle 306 adapted to the cross slider 302 is installed on the inner surface of the cross groove of the top plate 301. Under the action of the spring 304, a certain pushing force is applied to the cross slider 302, so that the cross slider 302 drives the locking plate 303 to stably fix the plug block 307 and stabilize the plug block 307 in the top plate 301. Even if a thief wants to open the zipper head 1, it will take a certain amount of time, and the user will notice in time.

[0040] like Figure 4 As shown, in this embodiment, a sliding hole adapted to the baffle 306 is provided on one side of the cross slider 302. The cross slider 302 is slidably connected to the outside of the baffle 306 through the sliding hole. A locking groove adapted to the locking plate 303 is provided on one side of the plug block 307. The locking plate 303 is movably locked inside the locking groove. Under the action of the baffle 306, when the spring 304 is compressed, it can block the spring 304 in the top plate 301, so that it can perform its function and prevent the spring 304 from popping out of the top plate 301.

[0041] Furthermore, after manually pulling the zipper head 1 upward, the tops of the first fabric strip 201 and the second fabric strip 202 come together. Manually push the push plate 305 towards the spring 304. The push plate 305 drives the cross slider 302 to move on the baffle 306. The cross slider 302 drives the locking plate 303 to move. The cross slider 302 applies pressure to the spring 304 and deforms, inserting the insertion block 307 into the top plate 301. Then, remove the pushing force applied to the push plate 305. Under the action of the spring 304, apply a reverse pushing force to the cross slider 302. The cross slider 302 drives the locking plate 303 to move, locking the locking plate 303 into the insertion block 307. This fixes the insertion block 307 in the top plate 301, completing the fixing of the zipper head 1.

[0042] Working principle: Place the bottoms of the first and second fabric strips 201 and 202 together, and place the closer ends of them into the zipper head 1. Manually pull the pendant 205 along the installation direction of the second fabric strip 202. The pendant 205 drives the zipper head 1 to move. With the assistance of the two separating teeth 206, the zipper teeth 203 on the two second fabric strips 202 and the first fabric strip 201 are sequentially separated. During the movement of the zipper head 1, several zipper teeth 203 on one side of the second fabric strip 202 and several zipper teeth 203 on one side of the first fabric strip 201 engage. At this time, the protrusions 207 on the zipper teeth 203 are engaged at the bottom of the corresponding zipper teeth 203 on the opposite side. Pull the zipper head 1 to the top of the first fabric strip 201 and the second fabric strip 202. After several zipper teeth 203 are aligned, the top ends of the first fabric strip 201 and the second fabric strip 202 are joined together. The push plate 305 is manually pushed towards the spring 304. The push plate 305 drives the cross slider 302 to move on the baffle 306. The cross slider 302 drives the locking plate 303 to move. The cross slider 302 applies pressure to the spring 304 and deforms. After the insertion block 307 is inserted into the top plate 301, the pushing force applied to the push plate 305 is removed. Under the action of the spring 304, a reverse pushing force is applied to the cross slider 302. The cross slider 302 drives the locking plate 303 to move and lock the locking plate 303 into the insertion block 307. The insertion block 307 is then fixed in the top plate 301, completing the fixing of the zipper head 1.

[0043] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
