Abstract
The utility model belongs to the technical field of chain tools, and particularly relates to a round pin used for a chain. The round pin used for the chain is characterized in that the round pin used for the chain comprises a semi-arc-shaped part, a flat panel is arranged on the lower portion of the semi-arc-shaped part, the flat panel and the semi-arc-shaped part are connected through an inclined face, an included angle is formed between the inclined face and the flat panel, and the include angle is between 120 degrees and 150 degrees. The round pin used for the chain is simple in structure, convenient to use and capable of saving materials while chain units are connected better.
Description
Technical field
The utility model belongs to chain apparatus technical field, relates in particular to a kind of chain round pin.
Background technique
Round pin is to be applied to one of material the most common in chain industry.It is used that it is mainly used for connecting chain unit.Current round pin be all generally to have adopted a whole tubular shape.But this type of round pin there will be following problem in concrete application: the one,, round pin is cylindrical, thus surperficial smoother, thus the assembling of chain unit is had to certain harm; The 2nd,, round pin is cylindrical, the use of material is relatively wasted.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, and a kind of chain round pin is provided, and its technological scheme is as follows:
A chain round pin, is characterized in that, described chain comprises half arcuate member with round pin, the bottom of half described arcuate member is provided with flat board, between described dull and stereotyped and half arcuate member, by inclined-plane, be connected, between described inclined-plane and flat board, form angle, described angle angle is 120 degree-150 degree.
Optimal way is that the center of one end of half described arcuate member is provided with projection.
The chain round pin that the utility model provides, when in use, only need to chain with round pin whole be placed between two chain units just passable.Because the bottom of half arcuate member is provided with flat board, so dull and stereotyped, make the connection between chain have more frictional force, make the connection of chain unit more stable.Between described dull and stereotyped and half arcuate member, by inclined-plane, be connected, between described inclined-plane and flat board, form angle, described angle angle is 120 degree-150 degree.By inclined-plane be arranged to there is good buffering between flat board and half arcuate member, can extend its service time.
The center of one end of half arcuate member described in the utility model is provided with projection.Can be so that chain be more convenient when in use with round pin by projection, convenient operation.
The utility model is simple in structure, easy to use, can when better connecting chain unit, more save material.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with Fig. 1, illustrate embodiment:
A kind of chain round pin, it is characterized in that, described chain comprises half arcuate member 1 with round pin, the bottom of half described arcuate member 1 is provided with dull and stereotyped 2, between described flat board 2 and half arcuate member 1, by inclined-plane 3, be connected, between described inclined-plane 3 and dull and stereotyped 2, form angle, described angle angle is 120 degree-150 degree.
Optimal way is that the center of one end of half described arcuate member 1 is provided with projection 4.
The chain round pin that the utility model provides, when in use, only need to chain with round pin whole be placed between two chain units just passable.Because the bottom of half arcuate member is provided with flat board, so dull and stereotyped, make the connection between chain have more frictional force, make the connection of chain unit more stable.Between described dull and stereotyped and half arcuate member, by inclined-plane, be connected, between described inclined-plane and flat board, form angle, described angle angle is 120 degree-150 degree.By inclined-plane be arranged to there is good buffering between flat board and half arcuate member, can extend its service time.
Claims (2)
