[0006] The latch box is movably connected with an unlocking rod which is arranged parallel to the latch rod and has a length less than that of the latch rod. The unlocking rod is radially extended outward to form an unlocking block which is arranged on the same side as the latch block. The unlocking block is connected to the inner wall of the latch box on the side opposite to the outside of the mesh plate through a second elastic member.

[0007] A limit block is provided in the latch box at a position facing the latch block and the unlocking block.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 8As shown, the present invention provides a bolt self-locking steel plate mesh,

[0033] It is formed by connecting a plurality of unit nets to each other, and the unit net includes a net plate 11, a plurality of latch boxes 21 fixed to the edge of the net plate 11, and a plurality of plug blocks 31 fixed to the edge of the net plate 11; wherein,

[0034] The latch box 21 is movably inserted with a latch rod 23 for connecting the plug block 31 of the adjacent unit net. One side of the latch rod 23 extends radially outward to form a latch block 24. The latch block 24 is connected to the inner wall of the latch box 21 on the side opposite to the outside of the mesh plate 11 through a first elastic member 210.

[0035] The latch box 21 is movably connected with an unlocking rod 26 which is arranged parallel to the latch rod 23 and has a length less than that of the latch rod 23. The unlocking rod 26 is radially extended outward to form an unlocking block 27 which is arranged on the same side as the latch block 24. The unlocking block 27 is connected to the inner wall of the latch box 21 on the side opposite to the outside of the mesh plate 11 through a second elastic member 211.

[0036] A limit block 29 is provided in the latch box 21 at the position facing the latch block 24 and the unlocking block 27. The limit block 29 is retractably connected to the latch box 21 along the radial direction of the latch rod 23 through a third elastic member 212. A guide surface that can slide relative to the limit block 29 is formed on the side of the latch block 24 and the unlocking block 27 that faces the outside of the mesh plate 11. A blocking surface that can block the limit block 29 is formed on the side of the latch block 24 and the unlocking block 27 that faces away from the guide surface. Figure 1 and Figure 2 As shown, in this embodiment, the mesh plate 11 is provided with a plurality of circular holes 12 arranged in a matrix, which can reduce the influence of wind pressure on the steel mesh. To prevent the steel mesh from being deformed during use, the edge of the mesh plate 11 is provided with an outer frame 13, the number of the latch boxes 21 is three, the number of the plug blocks 31 is also three, the latch boxes 21 and the plug blocks 31 are both fixed to the outer frame 13 position on the back of the steel mesh body, the latch boxes 21 and the plug blocks 31 are arranged opposite to each other, except that the latch boxes 21 and the plug blocks 31 are not arranged at the common edge position, the other edges of the mesh plate 11 are all fixed with latch boxes 21 or plug blocks 31, and they are all fixed in the middle position of the edge to ensure that the entire steel mesh is evenly stressed. All the connectors of the steel mesh of the present invention are located inside the latch boxes 21, which can avoid the situation where small parts fall during high-altitude construction, thereby improving the safety and efficiency of construction.

[0037] Better, such as Figures 4 to 8As shown, the length of the latch rod 22 and the unlocking rod 26 is greater than that of the latch box 21. Both sides of the latch box 21 are provided with a first opening for the latch rod 22 to pass through, and both sides of the latch box 21 are provided with a second opening for the unlocking rod 26 to pass through. The first opening and the second opening are both provided on the side plate close to the adjacent unit net and the side plate away from the adjacent unit net, so that when the latch rod 22 passes through the latch box 21, the passing end of the latch rod 22 can be inserted into the plug block 31. Furthermore, the latch block 24 is fixed to the middle position of the latch rod 22, and the unlocking block 27 is fixed to the front end of the unlocking rod 26, so that the unlocking rod 26 will not pass through the latch box 21 when locked, or the passing distance will not affect the connection with the adjacent net plate. In this embodiment, the first elastic member 210 is a spring, which is wound on the latch rod 22. When the limit block 29 blocks the blocking surface of the latch block, the first elastic member 210 is in a compressed state, and at this time, the latch rod 22 extends out of the latch box 21 and inserts into the plug block 31 of the adjacent unit network, thereby achieving connection with the adjacent unit network. The first push cap 25 is fixed to one end of the latch rod 22 away from the adjacent unit network to facilitate the pressing operation. The second elastic member 211 is a spring, which is wound on the unlocking rod 26. When the limit block 29 blocks the blocking surface of the unlocking block, the second elastic member 211 is in a compressed state. When the guide surface of the unlocking block 27 is close to the limit block 29, the second elastic member 211 is in the reset state. At this time, the end of the unlocking rod 26 close to the adjacent unit net is located inside the second opening close to the adjacent unit net. When the unlocking rod 26 is pushed toward the adjacent unit net, the guide surface of the unlocking block 27 causes the limit block 29 to move downward, so that the latch block 24 is moved to the side away from the adjacent unit net by the elastic force of the first elastic member 210, thereby unlocking the locking effect of the latch block 24, so that the latch rod 22 is separated from the plug block 31 of the adjacent unit net, and the unlocking operation is realized. The second pressing cap 28 is fixed to the end of the unlocking rod 26 away from the adjacent unit net to facilitate the pressing operation. Furthermore, at the second opening position of the latch box 21, a sleeve extends into the interior of the latch box 21, and the length of the sleeve is less than half of the distance from the unlocking block to the end of the unlocking rod 22 close to the outer end of the mesh plate 11. The through hole of the sleeve is opposite to the second opening. When the second elastic member 211 is in the reset state, the end of the unlocking rod 26 close to the adjacent unit net is located inside the sleeve. When the second push cap 28 is pressed to perform the unlocking operation, the sleeve has a guiding function, and can also prevent the end of the unlocking rod 26 close to the adjacent unit net from passing through the latch box 21 or pressing on the plug block 31 of the adjacent unit net, and will not affect the retraction of the latch rod 22.

[0038] Preferably, when the first elastic member 210 and the second elastic member 211 are in the reset state, the guide surfaces of the latch block 24 and the unlocking block 27 are located on the side of the limit block 29 facing away from the outside of the mesh plate 11, thereby preventing the first elastic member 210 and the second elastic member 211 from affecting the position of the limit block 29 when the latch box 21 is not operated, thereby affecting subsequent operations on the latch box 21.

[0039] Preferably, the guide surface is an inclined surface or an arc-shaped surface, so as to facilitate the downward movement of the guiding limit block 29.

[0040] Preferably, the limit block 29 is in the shape of a cuboid, and the blocking surface is a vertical surface. The blocking surface of this shape is more convenient for unlocking operation, and only the unlocking rod 26 needs to be pressed without any other operation.

[0041] Preferably, there are multiple third elastic members 212, and the multiple third elastic members 212 are arranged at intervals along the length direction of the cuboid. The multiple third elastic members 212 can ensure the normal reset of the limit block 29 and avoid insufficient elastic force during long-term use.

[0042] Preferably, when the third elastic member 212 is in the reset state, the top of the limit block 29 is higher than the bottom of the latch block 24 and the bottom of the unlocking block 27. When the third elastic member 212 is in the compressed state, the top of the limit block 29 is lower than the bottom of the latch block 24 and the bottom of the unlocking block 27. In this embodiment, the third elastic member 212 is a spring, which is wound around the unlocking rod 26, and the telescopic rod 23 is telescopic in the form of a parent-child rod, so as to achieve the blocking effect of the limit block 29.

[0043] Preferably, the third elastic member 212 is a spring, and at least one of the springs is inserted with a telescopic rod 23, and the telescopic rod 23 is fixed between the limit block 29 and the bottom plate of the latch box 21. The combination of the spring and the telescopic rod 23 realizes the normal telescopic function of the telescopic rod 23. The number of the telescopic rods 23 is two, and the two telescopic rods 23 are arranged between the limit block 29 and the bottom plate of the latch box 21 at intervals. Further, the number of the third elastic member 212 is also two, which are respectively wound around the outer circumference of the two telescopic rods 23. More preferably, an auxiliary spring is also connected between the limit block 29 and the bottom plate of the latch box 21, and the auxiliary spring is located between the two telescopic springs, thereby further improving the elastic force of the limit block 29 elastically moving up and down.

[0044] Preferably, Fig. 9As shown, the plug block 31 is provided with a horizontal plug hole 32 for horizontally splicing two mesh panels 11, and the plug block 31 is provided with a vertical plug hole 33 for vertically splicing two mesh panels 11. The horizontal plug is used to connect and fix two horizontally butted steel plate meshes, and the vertical plug hole 33 is perpendicular to the mesh panel 11 and is used at the corners of the frame to connect and fix two vertical steel plate meshes.

[0045] Preferably, Figure 1 , Figure 2 , Fig.10 and Fig.11 As shown, the back of the mesh plate 11 is cross-fixed with diagonal braces 14. The brace rod 16 is fixed at the intersection of the diagonal braces 14. In this embodiment, the outer ends of the diagonal braces 14 are fixed to the outer frame 13, thereby forming a supporting frame on the back of the mesh plate 11, which greatly improves the strength of the steel mesh.

[0046] Preferably, a support rod 16 for fixing the mesh panel 11 is fixed at the intersection of the diagonal support 14. A circular chassis 15 is formed at the intersection of the diagonal support 14 at the center of the mesh panel 11. A threaded hole is provided on the chassis 15, and a screwing section for screwing into the threaded hole is provided on the top of the support rod 16. During installation, the screwing section of the support rod 16 is aligned with the threaded hole of the chassis 15 and tightened. The support rod 16 is connected to the horizontal rod of the frame through a conventional fastener. The diagonal support 14 facilitates better force on the mesh panel 11. The circular chassis 15 is arranged in the center of the diagonal support 14. The support rod 16 is a hollow steel pipe to reduce the weight of the steel plate mesh.

[0047] Method of using the latch box 21: by pressing the first push cap 25, the latch rod 22 and the latch block 24 are driven to move forward, and the latch block 24 pushes the limit block 29 to move downward. The latch block 24 is fixed by the limit block 29, so that the latch rod 22 is in an exposed state and inserted into the horizontal socket 32 ​​of the fixed plug block 31 to fix the steel plate mesh outer frame 13; when disassembling, press the second push cap 28 to drive the unlocking rod 26 and the unlocking block 27 to move forward, and push the limit block 29 to move downward. Due to the action of the first elastic member 210, the latch rod 22 is pushed to retract to achieve the purpose of unlocking.

[0048] The present invention is installed by combining a latch box and an insert block, solving the technical problem of excessive and unstable installation parts of steel plate mesh in the prior art. When the present invention is used, the integrity is strong during the erection and dismantling of the frame, avoiding the loss of small parts, and reducing deformation and improving the overall strength through the combination of the diagonal brace and the support rod.
