Embodiment Construction

[0019] exist Figure 1 to Figure 8 Among them, the chain pin anti-tampering structure includes left chain piece 1, right chain piece 2, identification chain link 4, identification chain pin 3, first chain pin 5, first link link 6, dustproof sheet 7 and pad The sheet 8 is characterized in that a rounded truncated blind hole 9 is processed in the center of both ends of the identification chain pin 3, and the radial square groove 10 that is processed on the identification chain pin 3 is a radial square groove 10 that passes through the rounded truncated blind hole 9 to identify The radial square groove 10 centered on the central axis of the chain pin 3 is evenly distributed at a central angle of 60°. A slider 11 is inserted in the radial square groove 10, and a first positioning through hole 12 and a second positioning through hole 12 are processed on the slider 11. The through hole 13, the first round frustum block 14 is inserted in the rounded frustum-shaped blind hole 9, the s...

Abstract

The invention belongs to the field of chains, and particularly relates to a pin shifting preventing structure of a chain pin. The pin shifting preventing structure comprises a left chain piece, a right chain piece, an identification chain joint, an identification chain pin, a first-section chain pin, a first-section chain joint, a dustproof piece and gaskets; and inverted-circular-truncated-cone-shaped blind holes are machined in the centers of the two ends of the identification chain pin, radial square grooves which communicate with the inverted-circular-truncated-cone-shaped blind holes aremachined in the identification chain pin, the radial square grooves, taking the central axis of the identification chain pin as the center, are uniformly distributed with a central angle of 60 degrees, and sliding blocks are inserted into the radial square grooves. The pin shifting preventing structure has the beneficial effects that due to the design of bosses at the two ends of the identification chain pin, the chain pins are prevented from shifting.

Description

technical field [0001] The invention belongs to the field of chains, in particular to a chain pin anti-skimming structure. Background technique [0002] The traditional chain link and chain pin are easy to move during the working process, which will cause the chain to be disconnected or the chain will be broken due to uneven force. Contents of the invention [0003] In order to solve the problem of chain pin movement, the present invention proposes a chain pin anti-skimming structure. [0004] This chain pin anti-tampering structure includes a left chain piece, a right chain piece, an identification chain link, an identification chain pin, a first chain pin, a first link link, a dust-proof sheet and a gasket, and is characterized in that, in the identification chain There is a rounded truncated blind hole in the center of both ends of the pin, and the radial square groove processed on the identification chain pin is connected with the rounded truncated blind hole. The rad...
