Abstract

The utility model relates to a four-head thread bolt, including the bolt body, the top of bolt body is provided with the bolt head, a plurality of circles of screw thread have been seted up on bolt body surface, the screw thread of seting up on the bolt body is the parallel screw thread of marcing of four-head. The utility model discloses a bolt-up nature is good, and can realize twisting out, raises the efficiency that twists fast of bolt.

Description

Four-head threaded bolt

Technical Field

The utility model relates to a machine parts technical field especially relates to a four-head thread bolt.

Background

In some special positions, the screwing-in and screwing-out of the screw thread are troublesome, for example, the installation of an automobile brake pad is influenced by peripheral components, the fastening of the bolt cannot be conveniently adjusted, and how to realize the quick screwing-in and screwing-out of the bolt is a problem which is urgently needed to be solved at present.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a four-head thread bolt, the fastening nature is good, and can realize twisting out, raises the efficiency fast of bolt.

In order to achieve the above purpose, the utility model adopts the technical scheme that:

the utility model provides a four-head thread bolt, including the bolt body, the top of bolt body is provided with the bolt head, a plurality of circles of screw thread have been seted up on bolt body surface, the screw thread of advancing is the parallel screw thread of four-head of seting up on the bolt body.

Further, the pitch of the thread on the bolt body is 2.5 mm.

Furthermore, the threads of the threads on the bolt body are four-head advancing and parallel to each other, and the corresponding screw holes are internally provided with internal threads matched with the bolts.

Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages:

the utility model discloses a four-head thread bolt adopts the form that the four-head was gone forward and go forward and backward, twists the wrong income degree of depth that the round just can realize four rings of conventional bolt, effectively improves the packaging efficiency, especially to the subassembly position of more difficult operation, can accomplish the wrong income of bolt better and screw out.

Drawings

Some specific embodiments of the present invention will be described in detail hereinafter, by way of illustration and not by way of limitation, with reference to the accompanying drawings. The same reference numbers in the drawings identify the same or similar elements or components. Those skilled in the art will appreciate that the drawings are not necessarily drawn to scale. In the drawings:

fig. 1 is a schematic structural view of a four-start threaded bolt according to an embodiment of the present invention.

Wherein the reference numerals are as follows:

1. bolt body, 2, screw thread, 3, bolt head.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, 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.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

The embodiment describes and provides a four-head threaded bolt, as shown in fig. 1, the four-head threaded bolt comprises a bolt body 1, a bolt head 3 is arranged at the top of the bolt body 1, a plurality of circles of threads 2 are arranged on the surface of the bolt body 1, the threads 2 arranged on the bolt body 1 are threads 2 which run in parallel, one end of the bolt is the bolt head 3, and the other opposite end of the bolt is a flat head. The screw thread 2 that has on the bolt body 1 is four-head and advances altogether and parallel to each other, and has in the corresponding screw with bolt assorted internal thread.

In a further embodiment, the pitch of the threads 2 on the bolt body 1 is 2.5mm, so that the bolt head 3 on the bolt can be screwed in or out of the path depth of 2.5mm x 4=10mm along the axial direction of the bolt body 1 by rotating once, while the ordinary threaded bolt can only travel the depth of 2.5mm by rotating once, and it can be seen that the four-head threaded bolt of the embodiment rotates 4 times as much as the ordinary threaded bolt, and the operation efficiency can be effectively improved.

To sum up, the utility model discloses a four-head thread bolt adopts the form that the four-head was gone into one's turn and just can realize the wrong income degree of depth of four rings of conventional bolt, effectively improves the packaging efficiency, especially to the subassembly position of more difficult operation, can accomplish the wrong income of bolt better and screw out.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.

Claims
