Abstract

The utility model discloses a double-end stud with a limiting structure, which comprises a stud main body and is formed by integral cold heading, wherein the stud main body is sequentially provided with a first thread section, a limiting structure, a polished rod section, a second thread section, a pulling and twisting structure and a conical surface guide structure, and the exposed length is ensured to be accurately controlled; the hexagonal screwing structure is arranged, so that the assembly of a screwing end is convenient; the conical guide structure is convenient for aligning and guiding the through hole of the fastened part.

Description

Take limit structure's stud

Technical Field

The utility model relates to a vapour fastener technical field especially relates to a take limit structure's stud.

Background

The automobile assembling field needs often to use bolted connection, and the mode that adopts in the past is after welding weld bolt to a connector earlier, utilizes nut and another connector to connect fixedly, and this kind of connection has very big shortcoming in the in-service use: firstly, a welding procedure is added to weld a welding bolt to one of the connecting pieces before the two connecting pieces are assembled, and the welding can generate certain influence on the performance of the connecting piece; second, if the connection is replaced several times, the threads may wear or be damaged, making it impossible to replace the connection thread.

Along with the design of the fastener is more and more exquisite, the simple two-section screw thread of the double-end stud of the existing adds the middle polished rod structure, the convenience of use is very unfriendly, inconvenient screw in advance, and the screw in degree of depth of the screw-in end is difficult to control because of the processing length of the screw thread during use, the change is great, and then cause that the exposed length changes greatly, the problem that the exposed length is insufficient may appear in some scenes.

Disclosure of Invention

The utility model aims at providing a take limit structure's stud to it is inconvenient to revolve as and the uncontrolled problem of screw in degree of depth to solve.

In order to solve the technical problem, the utility model discloses an adopt following technical scheme to realize:

a stud with a limiting structure comprises a stud main body, wherein the stud main body comprises a first thread section 1, a polished rod section 2 and a second thread section 3 which are sequentially connected and constructed,

a limiting structure 4 is arranged between the first thread section 1 and the polished rod section 2, and the limiting structure 4 is a protruding structure which is radially outward on the shaft surface of the stud main body;

one end of the second thread section 3 is provided with a pulling and twisting structure 5, and one end of the pulling and twisting structure 5 is provided with a conical surface guide structure 6.

Further, the stud main body is of an integrally formed structure.

Further, the nominal diameters of the first thread segments 1 and the second thread segments 3 may be the same or different.

Further, the screwing structure 5 is a hexagonal screwing structure.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model provides a stud with a limit structure, which ensures the accurate control of the exposed length; the hexagonal screwing structure is arranged, so that the assembly of a screwing end is convenient; the conical guide structure is convenient for aligning and guiding the through hole of the fastened part.

Drawings

The invention will be further described with reference to the accompanying drawings:

FIG. 1 is a schematic view of a stud with a limiting structure;

in the above figures: 1. the device comprises a first thread section, a polished rod section 2, a second thread section 3, a limiting structure 4, a wrenching structure 5 and a conical surface guide structure 6.

Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the following detailed description of the present invention with reference to the accompanying drawings makes it clear that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the embodiment provides a stud with a limiting structure, which comprises a stud main body and is formed by integral cold heading, wherein the stud main body is sequentially provided with a first thread section 1, a limiting structure 4, a polished rod section 2, a second thread section 3, a wrenching structure 5 and a conical surface guide structure 6, and through the arrangement of the conical surface guide structure 6, the through hole of a fastened part is conveniently aligned and guided in.

The limiting structure 4 is a protruding structure which is arranged on the shaft surface of the stud main body along the radial direction and outwards and can be arranged into a flange plate or a protruding limiting round dot structure, and the exposed length is guaranteed to be accurately controlled through the arrangement of the limiting structure 4.

The nominal diameters of the first thread section 1 and the second thread section 3 can be different, so that the assembling requirements of nuts or mounting threaded holes with different specifications can be met.

The screwing structure 5 is a hexagonal screwing structure, and is convenient for assembling a screwing end of a stud.
