Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 7 As shown, the wire mesh snap fastener structure for preventing detachment proposed in this embodiment includes a snap fastener mechanism, a snap cover 2, and a detachable and convenient fastening mechanism.

[0029] The snap fastening mechanism includes: a snap plate 1, the four corners of which are bent to form U-shaped portions 101, the bottom front, top front, left front, and right front of which are bent to form flat insertion portions 102, and the two opposing flat insertion portions 102 are provided with locking holes 103 on their opposing sides; the four U-shaped portions 101 are used for the cross-shaped step formed by two steel wires in the wire mesh to be inserted, and each pair of opposing U-shaped portions 101 is used for the same steel wire to be inserted, and the cross-shaped position formed by the two steel wires is located in the middle of the front side of the snap plate 1;

[0030] The pressure cover 2 has positioning holes 201 at the bottom, top, left and right sides of the front side. The four flat insertion parts 102 move through the corresponding positioning holes 201. The pressure cover 2 has two positioning slots 203 on the front side. The pressure cover 2 is used to press and seal the two steel wires that are in a cross shape, and is used to conveniently insert the sleeve into the four flat insertion parts 102 through the four positioning holes 201 on its front side for insertion and positioning.

[0031] The detachable and convenient locking mechanism is installed in two locking holes 103 and two positioning slots 203; the detachable and convenient locking mechanism is used to lock the pressure cover 2 in a convenient manner with the two locking holes 103, and is also used for easy unlocking for subsequent disassembly and recycling.

[0032] In this embodiment, multiple first anti-slip protrusions are provided on the inner walls of both sides and the inner wall of the rear side of the U-shaped part 101; four sets of second anti-slip protrusions 202 are fixedly connected in a ring at equal intervals on the rear side of the pressure cover 2, with two protrusions in each set, and the second anti-slip protrusions 202 are on the same inclined line as the inner side of the corresponding U-shaped part 101; the four sets of second anti-slip protrusions 202 are used to press against the front side of the steel wire to perform anti-slip work when the pressure cover 2 is pressed backward.

[0033] Furthermore, such as Figure 1 , 3As shown in Figure 7, the detachable and convenient locking mechanism includes a horizontal tube 3, two locking posts 301, a compression spring 302 in a one-third compressed state, and two pull blocks 304. The horizontal tube 3 is located between two opposite flat insertion parts 102. The horizontal tube 3 is a tube with a square outer shape and a round inner shape. The two locking posts 301 are slidably sleeved inside the horizontal tube 3. The opposing ends of the two locking posts 301 are respectively movably locked in the corresponding locking holes 103 and are set as arc-shaped structures. The compression spring 302 is fixedly connected between the two locking posts 301. A rectangular through hole 303 is opened at the bottom of the horizontal tube 3. The two pull blocks 304 are respectively fixedly connected to the bottom of the corresponding locking posts 301. The bottom of the pull block 304 passes through the rectangular through hole 303 and extends to the outside of the horizontal tube 3.

[0034] In this embodiment, the bottom of the pull block 304 is set as a circular structure, and the front bottom of the pull block 304 is provided with a pull hole. The two pull holes are provided for personnel to perform auxiliary similar squeezing operations through external needle-nose pliers, so that personnel can flexibly apply them according to the site conditions.

[0035] In this embodiment, baffles 305 are fixedly connected to the adjacent sides of the two pull blocks 304. The bottom left side of the upper baffle 305 is in movable contact with the top right side of the lower baffle 305. The front and rear sides of the upper baffle 305 are in movable contact with the front and rear inner walls of the rectangular perforation 303, respectively. A U-shaped guide block 306 is fixedly connected to the bottom of the horizontal tube 3. The U-shaped guide block 306 is slidably sleeved on the outside of the lower baffle 305. The two baffles 305 are used to block and prevent impurities from entering the rectangular perforation 303, preventing external dust and impurities from entering the rectangular perforation 303 and compressing the spring 302, thus affecting subsequent use and improving the stability of long-term use.

[0036] In this embodiment, two positioning pins 307 are fixedly connected to the rear side of the horizontal tube 3. The two positioning pins 307 are respectively movably locked in the corresponding positioning slots 203. The two positioning pins 307 are used to lock into the two positioning slots 203 when the horizontal tube 3 is moved backward, so as to facilitate the locking and positioning of the horizontal tube 3 and improve the positional stability of the horizontal tube 3.

[0037] In this embodiment, the horizontal tube 3, two locking pins 301, a compression spring 302, and two pull blocks 304 work together. During assembly, the two pull blocks 304 are first squeezed in a similar manner to drive the two locking pins 301 to slide close together inside the horizontal tube 3, compressing the compression spring 302. This causes the locking pins 301 to retract into the horizontal tube 3. The horizontal tube 3 is then placed between two opposite flat insertion parts 102. The squeezing pressure on the two pull blocks 304 is then released. At this point, the compression spring 302, which is in a compressed state, drives the two locking pins 301 to repel each other and move back, respectively locking into the corresponding locking holes 103, thus achieving the desired alignment. The horizontal tube 3 is fixed in place, and the horizontal tube 3 is used to limit and fix the pressure cap 2 to prevent it from falling off. This further fixes and restricts the wire intersection of the wire mesh to prevent it from falling off. When disassembling, the two pull blocks 304 are squeezed together again to drive the two locking posts 301 to retract into the horizontal tube 3, so that they are separated from the two locking holes 103. This releases the locking state, so that when the wire mesh is damaged and needs to be replaced, the pressure buckle mechanism, pressure cap 2 and detachable locking mechanism can be easily disassembled. This achieves the effect of convenient, quick and easy fixed anti-fall-off assembly and disassembly recycling, avoiding the phenomenon of discarding and wasting parts later, and improving subsequent practicality.

[0038] It should be noted that the pressure cap 2, buckle plate 1, horizontal tube 3, clamping post 301, pull block 304, baffle 305 and U-shaped guide block 306 are all preferably made of stainless steel. The advantages of stainless steel are high hardness, high wear resistance and good maintenance-free effect, which ensures long-term application stability.

[0039] The method of use in this embodiment is as follows: When using the anti-detachment wire mesh snap fastener structure, insert the cross-shaped step formed by two steel wires in the wire mesh into the inside of the four U-shaped parts 101, so that the cross-shaped position is located in the middle of the front side of the snap plate 1. Move the pressure cover 2 backward so that it drives the four positioning insertion holes 201 to respectively fit onto the corresponding flat insertion part 102. The pressure cover 2 drives the four sets of second anti-slip protrusions 202 to press the steel wires backward to prevent slippage. Then, squeeze and drive the two pull blocks 304 in a similar manner to drive the two locking posts 301 to slide close together in the horizontal tube 3, and compress the compression spring 302. The two pull blocks 304 drive the two baffles 305 to move close together, so that the locking posts 301 retract into the horizontal tube 3, and place the horizontal tube 3 in a left-right position. Between the two flat insertion parts 102, the horizontal tube 3 drives the two positioning pins 307 to be inserted into the two positioning slots 203, which achieves the effect of conveniently positioning the horizontal tube 3 and improving the positional stability of the horizontal tube 3. Then, the close pinching pressure on the two pull blocks 304 is released. At this time, the compression spring 302, which is in a compressed state, drives the two pins 301 to repel each other and move back, and respectively insert into the corresponding pin holes 103, thereby realizing the fixing of the horizontal tube 3. The horizontal tube 3 is used to limit and fix the pressure cover 2 to prevent it from falling off, and further fixes and limits the wire crossing part of the wire mesh to prevent it from falling off. This achieves the effect of convenient and quick anti-dislodgement fastening of the two wire crossing parts of the screw without tools, without the need for separate tools for fixing, thus improving the convenience and efficiency of operation.

[0040] During disassembly, the two pull blocks 304 are squeezed together again, causing the two locking posts 301 to retract into the horizontal tube 3, separating them from the two locking holes 103. This releases the locking mechanism, allowing the snap-fit ​​mechanism, the cover 2, and the detachable convenient locking mechanism to be separated. This facilitates easy disassembly of the snap-fit ​​mechanism, cover 2, and detachable convenient locking mechanism when the wire mesh needs to be replaced due to damage. It achieves the effect of convenient, quick, and easy fixing, anti-detachment assembly, and disassembly recycling, avoiding the waste of discarded parts and improving subsequent practicality. The two baffles 305 are used to block the rectangular perforation 303, preventing external dust and impurities from entering the internal locking spring 302 through the rectangular perforation 303 and affecting subsequent use, thus improving the stability of long-term use.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
