Description

Technical Field

[0001] The utility model belongs to the technical field of iron chains, and particularly relates to a large-scale iron chain with an anti-fracture structure. Background Art

[0002] In people's production and life, iron chains are widely used and can be seen everywhere. Iron chains are made of iron wires by machine weaving. Iron chains are usually divided into two categories according to their uses: iron chains for ornaments and iron chains for industry. Due to different usage requirements, the requirements for iron chains in industrial chains are also different.

[0003] At present, for small iron chains, they are usually made of a single steel bar or iron wire, which are bent and then welded after being formed. For large-scale iron chains, due to the difficulty of single bending, steel columns are usually bent into "U"-shaped components, and two "U"-shaped components are butt-jointed and welded to form a large-scale iron chain.

[0004] After the iron chain is used for a long time and continuously affected by strong tensile forces, it is very easy to break at the welded position.

[0005] It is found that in the prior art, the Chinese utility model patent with the authorization announcement number CN216478697U discloses "an iron chain with an anti-fracture structure", which includes an iron chain body composed of a plurality of iron rings buckled together. Anti-fracture sheaths are fixedly sleeved on the outer surfaces of both sides of the iron chain body. A plurality of force-dividing rib strips are arranged on the anti-fracture sheaths. Reinforcing support rods are fixedly connected to the opposite sides of the anti-fracture sheaths. Shot peening layers and wear-resistant sliding layers are sequentially arranged on the iron chain body, the anti-fracture sheaths and the reinforcing support rods from the inside to the outside, and annular reinforcing ribs are arranged inside the iron chain body.

[0006] For the iron chains in the prior art including the above, although protective measures are set, only the wear resistance of the iron chain is improved. Although it has a certain anti-fracture effect, the effect is not good because the main reason for the fracture of the iron chain is that the iron chain is instantaneously subjected to a relatively high impact force or is in a state of strong tension for a long time (assuming that the quality of the iron chain itself is qualified and there is no intentional damage by humans), and in actual use, the staff will regularly inspect the iron chain, and the iron chains with relatively serious wear will be repaired or replaced and will not be put into use again. Therefore, how to improve the tensile and impact resistance of the iron chain is the key to improving the anti-fracture performance of the iron chain.

[0007] To solve the above problems, a large-scale iron chain with an anti-fracture structure is proposed in this application. Utility Model Content

[0012] I-shaped insertion block, the I-shaped insertion block is embedded in the T-shaped groove and welded and fixed to the U-shaped part.

The link 11 includes: a U-shaped part 111, a strengthening connection mechanism 112, and an I-shaped insert block 113.

[0031] Further, by Figures 1-4As shown in the figure, in this embodiment, two U-shaped members 111 are symmetrically distributed, and a T-shaped groove 1111 is provided at the end of the U-shaped member 111. The strengthening connection mechanism 112 includes two symmetrically distributed first semi-circular rings 1121, a strengthening connecting rod 1122 fixed between the two first semi-circular rings 1121, and two symmetrically distributed second semi-circular rings 1123.
