Description

Technical Field

[0001] This utility model relates to the field of metal mesh technology, specifically to an anti-fatigue metal mesh. Background Technology

[0002] Metal mesh, as a common structural material, is widely used in fields such as construction, transportation, machinery, and protection, for example, in building reinforcement, screening and filtration, and safety protection.

[0003] Traditional metal mesh is prone to local deformation, breakage, or even overall failure when subjected to dynamic loads or periodic impacts over a long period of time due to stress concentration and vibration fatigue, which affects its service life and safety performance. In addition, it is not convenient to replace the metal mesh independently when it is deformed or damaged, and the entire metal mesh needs to be replaced when it is damaged, which increases costs.

[0004] Therefore, a fatigue-resistant metal mesh was proposed. Utility Model Content

In addition, when the metal mesh is deformed and damaged, it is not convenient to replace the metal mesh independently. When the metal mesh is damaged, it needs to be replaced as a whole, which increases the cost.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A fatigue-resistant metal mesh includes a lower frame, with positioning holes around the top surface of the lower frame. Positioning posts are inserted into the positioning holes, and an upper frame is fixedly mounted on the top of each positioning post.

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

[0028] like Figure 1-8As shown, an anti-fatigue metal mesh includes a lower frame 1. Positioning holes are provided around the top surface of the lower frame 1. Positioning posts 2 are inserted into the positioning holes. An upper frame 3 is fixedly installed on the top of the positioning posts 2. By setting the upper frame 3 and the lower frame 1, fixing pieces 4 are sequentially inserted into the lower frame 1, and metal ribs 6 are arranged and installed. Then, the positioning posts 2 are inserted into the positioning holes, so that the upper frame 3 and the lower frame 1 can be quickly positioned and connected. At this time, the upper connecting piece 8 and the lower connecting piece 10 are attached. The connecting stud 9 is turned to fix the upper frame 3 and the lower frame 1. When some of the metal ribs 6 are deformed and damaged, the upper frame 3 and the lower frame 1 can be disassembled to replace the metal ribs 6 independently without replacing the whole structure, thus saving costs.

[0029] Square grooves are provided on the surfaces of both the lower frame 1 and the upper frame 3. Fixing plates 4 are inserted into the interior of the square grooves. A damping component 5 is fixedly installed on one side of the fixing plate 4. A metal rib 6 is fixedly installed at one end of the damping component 5. The surface of the metal rib 6 is coated with a protective layer group 7. With the damping component 5 and the protective layer group 7, when the metal mesh is subjected to external impact, the carbon fiber layer 702 provides high modulus support, which can suppress the overall deformation of the metal mesh. The polyurethane layer 703 is used to dissipate vibration energy. At the same time, the metal rib 6 will pull the damping spring 501 to deform it. The damper 502 plays a damping role, which achieves the effect of buffering and shock absorption of the impact force on the metal rib 6, and improves the fatigue resistance of the metal mesh. Reinforcing strips 12 are fixedly installed on the edges of both the lower frame 1 and the upper frame 3.

[0030] like Figure 5 and Figure 6 As shown, the shock absorption assembly 5 includes a shock absorption spring 501 and a damper 502. One end of the shock absorption spring 501 and the damper 502 is fixedly connected to the fixing plate 4. The damper 502 is sleeved inside the shock absorption spring 501. The other end of the shock absorption spring 501 and the damper 502 are both fixedly connected to the metal rib 6.

[0031] With the setting of the shock absorption component 5, when the metal rib 6 is impacted, it will pull the shock absorption spring 501 to deform it, and the damper 502 will play a damping role, thus achieving the effect of buffering and shock absorption of the impact force on the metal rib 6.

[0032] like Figure 5 As shown, the protective layer group 7 includes a coupling agent layer 701, a carbon fiber layer 702 and a polyurethane layer 703. The coupling agent layer 701 is fixedly disposed on the surface of the metal rib 6, the carbon fiber layer 702 is fixedly disposed on the surface of the coupling agent layer 701, and the polyurethane layer 703 is fixedly disposed on the surface of the carbon fiber layer 702.

[0033] With the protective layer group 7, the carbon fiber layer 702 provides high modulus support, which can suppress the overall deformation of the metal mesh, and the polyurethane layer 703 is used to dissipate vibration energy and improve the fatigue resistance of the metal mesh.

[0034] like Figure 3 and Figure 4 As shown, upper connecting pieces 8 are fixedly installed around the outer surface of the upper frame 3. The top surface of the upper connecting piece 8 is provided with connecting screw holes, and the internal threads of the connecting screw holes are penetrated by connecting studs 9.

[0035] The connecting stud 9 serves to fix the upper connecting piece 8 and the lower connecting piece 10.

[0036] like Figure 7 and Figure 8 As shown, lower connecting pieces 10 are fixedly installed around the outer surface of the lower frame 1. The top surface of the lower connecting piece 10 is provided with a limiting hole that matches the connecting stud 9. The bottom of the connecting stud 9 is threaded with a nut 11.

[0037] The nut 11 serves to lock the connecting stud 9 in place.

[0038] like Figure 6 As shown, a positioning slot is provided on one side of the square groove, and the top and bottom of the fixing piece 4 are both fixed with protruding insertion parts that are adapted to the positioning slot.

[0039] The square groove and positioning slot are used to position the fixing piece 4.

[0040] like Figure 2 As shown, there are several groups of fixing plates 4 and metal ribs 6, and these groups of fixing plates 4 and metal ribs 6 are distributed sequentially along the axial direction.

[0041] The fixing plate 4 and the metal rib 6 are designed to form a detachable metal mesh.

[0042] The working principle of this utility model is as follows: the fixing piece 4 is inserted into the lower frame 1 in sequence, the metal ribs 6 are arranged and installed, and then the positioning post 2 is inserted into the positioning hole, so that the upper frame 3 and the lower frame 1 can be quickly positioned and connected. At this time, the upper connecting piece 8 and the lower connecting piece 10 are attached. The connecting stud 9 is turned to fix the upper frame 3 and the lower frame 1. When some of the metal ribs 6 are deformed and damaged, the upper frame 3 and the lower frame 1 can be disassembled to replace the metal ribs 6 independently without replacing the whole frame, thus saving costs.

[0043] When the metal mesh is subjected to external impact, the carbon fiber layer 702 provides high modulus support, which can suppress the overall deformation of the metal mesh. The polyurethane layer 703 is used to dissipate vibration energy. At the same time, the metal rib 6 will pull the damping spring 501 to deform it. The damper 502 plays a damping role, buffering and reducing the impact force on the metal rib 6, thus improving the fatigue resistance of the metal mesh.
