Description

Hot riveting type thrust rod

Technical Field

The utility model relates to a distance rod especially relates to a hot riveting formula distance rod, and it belongs to distance rod technical field.

Background

At present, the hot riveting process is mostly adopted to manufacture the rod head and the connecting rod in the market, but the defects of the thrust rod are as follows: the inner walls of the connecting rods are equal, the rod head needs to be forged, the tail of the rod head needs to be provided with a groove and is integrated with the connecting rods in a hot pressing mode, the groove at the tail of the rod head and the pressure-connected part of the pipe fitting have fracture caused by strain and local point stress, the service life of the rod head is short, and the use requirement cannot be met; the existing solution is to select a thicker seamless tube for the connecting rod part of the integral thrust rod, so that the cost investment is increased, and the economic benefit is not sufficient. Therefore, a new type of thrust rod is needed to solve the technical problems in the prior art.

SUMMERY OF THE UTILITY MODEL

The utility model aims at: for overcoming the defects in the prior art, the hot riveting type thrust rod is provided, the part of the inner wall of the connecting rod which is abutted against the rod head adopts a local thickening design, the service life of the thrust rod is prolonged, and the processing cost is reduced.

The utility model provides an above-mentioned technical problem's technical scheme as follows:

the utility model provides a hot riveting formula distance rod, includes the connecting rod and connects in the pole head at connecting rod both ends, pole head afterbody cover is established inside the connecting rod, the inside butt department with the pole head afterbody of connecting rod is the local shape that adds thickly.

Furthermore, the connecting rod comprises a first section, a second section and a third section which are sequentially communicated from left to right; the first section and the third section are symmetrically distributed, the joint of the first section and the second section is respectively abutted against the tail of the club head, and the wall thickness of the joint is greater than that of the second section.

Furthermore, a plurality of annular grooves are distributed on the outer surface of the tail part of the club head in an array mode, and convex ribs matched with the shapes of the grooves are arranged on the inner surfaces of the first section and the third section.

Furthermore, the outer surfaces of the first section and the third section are in a wave-shaped structure.

Compared with the prior art, the beneficial effects of the utility model are that: the butt department through with the connecting rod inside and pole head afterbody sets up to local thickening form, can effectively solve the inhomogeneous condition of atress, improves the life of distance rod, reduces the processing cost, satisfies the operation requirement in market.

In the figure, 1, a connecting rod; 101. a first stage; 102. a second stage; 103. a third stage; 2. a club head.

Detailed Description

The principles and features of the present invention will be described with reference to fig. 1 and 2, which are provided for illustration only and are not intended to limit the scope of the invention.

The utility model provides a hot riveting formula distance rod, includes connecting rod 1 and connects in the pole head 2 at 1 both ends of connecting rod, 2 surfaces of pole head are provided with the hollow structure who connects the sphere round pin, 2 afterbody covers of pole head establish connect in 1 inside of connecting rod, 1 inside and the butt department of 2 afterbody of pole head of connecting rod are the local and add thick form, as shown in figure 1.

The connecting rod 1 comprises a first section 101, a second section 102 and a third section 103 which are sequentially communicated from left to right; the first section 101 and the third section 103 are symmetrically distributed, the joints of the first section and the second section 102 are respectively abutted against the tail part of the club head 2, and the wall thickness of the joints is greater than that of the second section 102.

A plurality of annular grooves are distributed on the outer surface of the tail part of the club head 2 in an array mode, and convex ribs matched with the shapes of the grooves are arranged on the inner surfaces of the first section 101 and the third section 103.

The outer surfaces of the first section 101 and the third section 103 are in a wave-shaped structure, and the structure is in an external shape formed in the hot riveting process.

Thrust rod among the prior art has the atress inequality to lead to the cracked condition, as shown in figure 2, if want to solve this type of problem, need increase the thrust rod wall thickness, nevertheless consider the material cost of whole thrust rod, whole thick mode is inadvisable, so provide a neotype thrust rod, adopt local thick form with the butt department of 2 afterbody of pole head in connecting rod 1 inside promptly, can satisfy the life of thrust rod, can reduce the processing cost again, satisfy the user demand on the market.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
