The plum-blossom hole (1) is Hexagonal deformation shape; each corner of the plum blossom hole (1) protrudes outward to form a small arc (3), and each side of the hexagon is concave inward to form a large arc (4 ), the small arc (3) adjacent to the corner is tangent to the large arc (4) of the side; the plum blossom end of the utility model can be matched with various parts, has higher strength, and is Good performance.

Description

a plum blossom end

technical field

The utility model relates to the field of piston rod ends, in particular to a plum blossom end.

Background technique

Most of the existing piston rod ends are simple in structure and single in function, and each type of end generally can only be connected with another end of a specific structure. Although there are also a small number of terminals that can be connected with corresponding other various terminals, their strength is not ideal.

Utility model content

(1) Technical problems to be solved

Aiming at the deficiencies in the prior art, the utility model provides a plum blossom end with good strength and adaptable to various parts.

(2) Technical solution

In order to achieve the above purpose, the utility model provides a plum blossom hole at one end of the plum blossom end, and a threaded hole at the other end of the plum blossom end, and the plum blossom hole is a regular hexagon. Each corner of the hexagon of the plum blossom hole protrudes outwards to form a small arc, and each side of the hexagon is recessed inward to form a large arc. The small arcs adjacent to the corners are tangent to the large arcs of the sides.

Compared with other polygons with more sides, the hexagonal structure has more stable sides, and the protrusions inside and parts are thicker, so it has the characteristics of good strength and high matching degree. On the other hand, compared with other polygons with fewer sides, the hexagonal structure can maximize the cooperation with other parts. The hexagonal structure can be matched with linear, triangular, rectangular, and hexagonal structures.

Furthermore, the corners and sides of the plum blossom hole are deformed into arc shapes, which can effectively reduce stress concentration and further improve the strength and performance of the plum blossom hole.

(3) Beneficial effects

The plum-blossom end of the utility model can be matched with various parts, and has higher strength and better performance.

Detailed ways

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

The structure of a plum-blossom end of the present utility model is shown in Figure 1 and Figure 2, and one end of the plum-blossom end has a plum-blossom hole 1, and the other end of the plum-blossom end has a threaded hole 2, and the plum-blossom Hole 1 is a regular hexagon.

Each corner of the plum blossom hole 1 hexagon protrudes outwards to form a small arc 3, and each side of the hexagon is inwardly recessed to form a large arc 4, and the small arc 4 adjacent to the corner 3 is tangent to the great arc 4 of said side.

Compared with other polygons with more sides, the hexagonal structure has more stable sides, and the protrusions inside and parts are thicker, so it has the characteristics of good strength and high matching degree. On the other hand, compared with other polygons with fewer sides, the hexagonal structure can maximize the cooperation with other parts. The hexagonal structure can be matched with linear, triangular, rectangular, and hexagonal structures.

Furthermore, the corners and sides of the plum blossom hole are deformed into arc shapes, which can effectively reduce stress concentration and further improve the strength and performance of the plum blossom hole.

The beneficial effect of the utility model: it can be matched with various parts, has higher strength and better performance.

The above is only the preferred embodiment of the utility model, and it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, some improvements and modifications can also be made. And retouching should also be regarded as the protection scope of the present utility model.

Claims (2)

1. a plum blossom termination is characterized in that, an end of described plum blossom termination has plum blossom hole (1), and the other end of described plum blossom termination has tapped hole (2), and described plum blossom hole (1) is regular hexagon.

2. plum blossom as claimed in claim 1 termination, it is characterized in that, hexagonal each the angle outer lug of described plum blossom hole (1) is small arc-shaped (3), institute hexagonal every limit of telling is the recessed orthodrome (4) that is inwardly, and the small arc-shaped at adjacent described angle (3) is tangent with the orthodrome (4) on described limit.
