Abstract
The utility model is related to a kind of novel chain ring connection structures.Its main feature is that：It is formed by half chain link of two c-types by pin connection, wherein intermediate protruding formation boss on the inside of the first half chain links, and intermediate inwardly stretch out forms groove on the inside of the second half chain links, and mounting hole (1) is respectively equipped on the boss and groove；The cross section of wherein the first half chain link intermediate straight portions (2) is round and the cross section of both ends arcuate portion (3) be semicircle, and the cross section of the second half chain link intermediate straight portions (2) be circle and the cross section of both ends arcuate portion (3) is semicircle.Test proves that after using the bindiny mechanism of the utility model, chain link when assembling only needs convex, the female members on two and half chain links to be mutually anchored to together, then be fixed together with axis pin of the spring, greatly facilitates installation.
Description
Technical field
The utility model is related to a kind of novel chain ring connection structures.
Background technology
Chain link connection at present relies primarily on half external chain link, expensive, processes a set of half chain link, needs using special
Tooling, special cutter, processing is very difficult, is susceptible to dislocation, it is difficult to which assembling causes unqualified, waste product to occur.
Utility model content
The purpose of this utility model is to provide a kind of processing novel chain ring connection structure simple, at low cost.
A kind of novel chain ring connection structure, is particular in that：It is formed by half chain link of two c-types by pin connection,
Intermediate protruding formation boss on the inside of wherein the first half chain links, and intermediate inwardly stretch out forms groove on the inside of the second half chain links,
Mounting hole is respectively equipped on the boss and groove；Wherein the cross section of the first half chain link intermediate straight portions to be round both ends
The cross section of arcuate portion is semicircle, the cross sections of the second half chain link intermediate straight portions both ends arcuate portion to be round
Cross section is semicircle.
Wherein pin connection is specifically to be connected using axis pin of the spring.
Test proves that after using the bindiny mechanism of the utility model, chain link is only needed when assembling two and half chain links
On convex, female members be mutually anchored to together, then be fixed together with axis pin of the spring, greatly facilitate installation.During dismounting only
Axis pin of the spring need to be taken out, connector can be opened.The chain link connection structure of the utility model is simple, easy to process, dismounting side
Just.
Description of the drawings
Attached drawing 1 is the structure diagram of the utility model；
Attached drawing 2 is the structure diagram of the second half chain links in the utility model；
Attached drawing 3 is the structure diagram of the first half chain links in the utility model.
Specific embodiment
As shown in Figure 1, 2, 3, the utility model provides a kind of novel chain ring connection structure, by half chain link of two c-types
It is formed by pin connection, is specifically connected using axis pin of the spring.Intermediate inwardly stretch out forms boss on the inside of wherein the first half chain links,
And intermediate inwardly stretch out forms groove on the inside of the second half chain links, and mounting hole 1 is respectively equipped on the boss and groove；First chain half
The cross section of ring intermediate straight portion 2 be round and the cross section of both ends arcuate portion 3 be it is semicircle, it is straight among the second half chain links
The cross section of line part 2 is circle and the cross section of both ends arcuate portion 3 is semicircle.
The application method and operation principle of the utility model be：
Chain link structure provided by the utility model is assemblied to form by half chain link of the c-type of two structure almost symmetries, the
Half chain link and the second half 2 cross sections of chain link intermediate straight portion are solid circles, and both ends arcuate portion 3 is solid half
Circle, together, it is as complete that the arcuate portion 3 of the two is overlapped mutually its cross section for such the first half chain link and the second chain half latch closure
Whole circle, then axis pin of the spring is installed by the mounting hole 1 on boss and groove two and half chain links can be assembled into one
Complete chain link.It needs to remove axis pin of the spring during dismounting.
