Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metal meshes, in particular to a tensile resistance device for metal meshes. Background Art
[0002] A metal mesh is a mesh structure made of metal wires or metal strips through processes such as weaving, welding, stamping, etc. The materials of metal meshes are diverse, and common ones include stainless steel, iron wire, copper wire, aluminum wire, etc. The shapes and sizes of its mesh holes can be designed and made according to different requirements, such as square, round, diamond-shaped, etc., and the mesh hole sizes range from a few millimeters that are tiny to dozens of centimeters that are relatively large.
[0003] Since the metal mesh is relatively soft in texture, it is extremely vulnerable to the influence of external tensile forces during actual use. However, there is a lack of a device on its exterior that can resist tensile forces. In this way, the tensile force may cause the shape of the mesh holes of the metal mesh to change and become no longer regular and uniform. Moreover, excessive stretching will cause plastic deformation of the metal wires of the metal mesh, thereby weakening its tensile strength. Various damages caused by the tensile force will greatly reduce the service life of the metal mesh, resulting in a substantial increase in the costs required for replacement and maintenance. Content of the Utility Model
[0004] The purpose of the utility model is to provide a tensile resistance device for metal meshes, achieving the purpose of effectively resisting the tensile forces received by the metal meshes.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A tensile resistance device for metal meshes, including a metal mesh and a fixed frame. Connection grooves are opened on the inner wall of the fixed frame, and the metal mesh is movably connected to the fixed frame through the connection grooves. Installation grooves are symmetrically opened on both sides of the inner wall of the fixed frame respectively, and engaging holes are equidistantly opened on both sides of the outer wall of the fixed frame respectively. The engaging holes are communicated with the installation grooves and the connection grooves, and a tensile resistance component is arranged outside the fixed frame.

[0014] (1) By rotating the rotary block, the rotary block drives the threaded rod to rotate. When the threaded rod rotates, it drives the pressing plate to move towards the fixed frame. At the same time, the pressing plate slides inwards on the outer wall of the first connecting rod. When the pressing plate moves, it squeezes the second fixing plate inwards, and the second fixing plate squeezes the fixed frame, making the size of the connecting groove formed in the fixed frame gradually smaller, thereby fixing the metal mesh, achieving the effect of fixing the edge of the metal mesh and preventing the edge of the metal mesh from detaching from the inside of the fixed frame due to stretching.
[0015] (2) By pulling the handle outwards, the handle drives the engaging rod to be pulled outwards through the movable plate, separating the two engaging rods. At the same time, the movable plate slides on the outer wall of the second guide rod, and the movable plate drives the spring to be stretched. Then, the reinforcing rods are evenly placed inside the installation groove, aligning the fixing holes of the reinforcing rods with the engaging holes of the fixed frame. Release the handle, and the spring rebounds, driving the movable plate to move inwards on the outer wall of the second guide rod. At the same time, the movable plate drives the engaging rod to engage into the engaging hole of the fixed frame and the fixing hole of the reinforcing rod. At the same time, the two engaging rods are attracted and fixed by the magnets, achieving the effect of increasing the strength between the metal mesh and the fixed frame through the reinforcing rods and improving the anti-stretching performance of the metal mesh.

A connection groove is provided on the inner wall of the fixed frame 2, and the metal mesh 1 is movably connected to the fixed frame 2 through the connection groove. Installation grooves 4 are symmetrically provided on both sides of the inner wall of the fixed frame 2, and engaging holes are equidistantly provided on both sides of the outer wall of the fixed frame 2. The engaging holes are communicated with the installation grooves 4 and the connection groove. An anti-tensile assembly 3 is provided outside the fixed frame 2. The anti-tensile assembly 3 includes: fixing components 31 symmetrically arranged on both sides of the fixed frame 2; reinforcing components 32 symmetrically arranged on the other two sides of the fixed frame 2. The fixing components 31 include: first fixing plates 311 symmetrically and equidistantly fixedly installed on the back of the fixed frame 2; threaded rods 317 symmetrically and movably connected to the front of the fixed frame 2. A connecting plate 312 is fixedly installed on the inner side of the first fixing plate 311, and a second fixing plate 313 is fixedly installed on the other side of the connecting plate 312. The size of the connecting plate 312 is the same as that of the fixed frame 2. The first fixing plate 311, the connecting plate 312, and the second fixing plate 313 are engaged outside the fixed frame 2. A first connecting rod 314 is fixedly sleeved inside the second fixing plate 313. One end of the first connecting rod 314 is fixedly connected to the fixed frame 2, and a first limiting plate 315 is fixedly installed at the other end of the first connecting rod 314. A pressing plate 316 is sleeved on the outer wall of the first connecting rod 314.
