Abstract
The utility model discloses a cylindrical pin comprising a cylindrical pin body (1), wherein the circumferential outer wall of the pin body (1) is provided with a circumferential seal groove (2) which is an arc-shaped circumferential seal groove. The utility model has the advantages of enhancing the sealing performance and effectively preventing the generation of oil leakage.
Description
Technical field
The utility model relates to a kind of straight pin.
Background technique
At present; the prior art cylindrical pin is generally one section solid cylindrical body; this straight pin is simple in structure; and all be to rely on a small amount of interference fit to be fixed in the pin-and-hole of part usually, still, because straight pin is in assembly process; its outer circumferential walls is through regular meeting's power effect outside improperly under the situation and be scratched; thereby local cut occurs, influence its sealability, cause oil leakage phenomenon to take place.
The model utility content
The technical problems to be solved in the utility model is, provides a kind of and can improve sealability, effectively prevents the straight pin that oil leakage phenomenon takes place.
For solving the problems of the technologies described above, the utility model provides a kind of straight pin that adopts following structure, comprises cylindrical shank; The outer circumferential walls of described shank is provided with circumferential seal groove.
After adopting said structure, the utlity model has following advantage: compared with prior art, because the utility model is provided with a circumferential seal groove on the outer circumferential walls of shank, therefore the user can improve sealability by be nested with seal ring on circumferential seal groove, thereby effectively prevents the generation of oil leakage phenomenon.
Description of drawings
Accompanying drawing is the structural representation of the utility model straight pin.
Shown in the figure 1, shank, 2, circumferential seal groove.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in drawings, in this specific embodiment, the utility model straight pin comprises cylindrical shank 1; The outer circumferential walls of described shank 1 is provided with circumferential seal groove 2; Described circumferential seal groove 2 is the arc circumferential seal groove.
Claims (2)
1. a straight pin comprises cylindrical shank (1), it is characterized in that: the outer circumferential walls of described shank (1) is provided with circumferential seal groove (2).
2. straight pin according to claim 1 is characterized in that: described circumferential seal groove (2) is the arc circumferential seal groove.
