Abstract
The utility model relates to a stud connecting structure which comprises a first part and a second part, wherein threaded holes are respectively formed in the first part and the second part, and the first part is connected with the second part through the threaded holes and a stud body. The stud connecting structure is characterized in that threads are arranged at the two ends of the stud body, and the thread pitch of the threads at one end of the stud body is larger than the thread pitch of the threads at the other end of the stud body. A through hole communicated with a threaded hole of the first part is formed in the bottom of the threaded hole of the first part. According to the stud connecting structure, gradual fixing of the two parts in interference fit with each other can be guaranteed in assembling, and also gradual separation of the two parts in interference fit with each other can be guaranteed in dismounting.
Description
Technical field
The utility model relates to a kind of stud bolt, especially a kind of stud bolt linkage structure.
Background technique
In mechanical structure, commonly used to two parts interference fit install, dismounting, uses general bolt, what problem is installed for the parts of two interference fit does not have, but during dismounting, take out bolt after, the parts that separate two interference fit are more time-consuming, require great effort.If these two parts, one of them parts can not torn open after installing substantially, but another parts need often to change some similar modules, and is then cumbersome especially.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of stud bolt linkage structure is provided, and when this stud bolt can guarantee to assemble, the parts of two interference fit were fixing gradually, in the time of also can guaranteeing to dismantle, the parts of two interference fit separate gradually.
According to the technological scheme that the utility model provides, described stud bolt linkage structure comprises first parts and second parts, is respectively equipped with tapped hole at first parts and second parts, and first parts are connected with second parts by tapped hole, stud bolt body; Feature is: the two ends at described stud bolt body are equipped with screw thread, and the pitch of threaded one end is greater than the pitch of the other end screw thread.
Bottom at the tapped hole of described first parts is provided with the through hole that is communicated with this tapped hole.
When stud bolt linkage structure described in the utility model can guarantee to assemble, the parts of two interference fit were fixing gradually, and in the time of also can guaranteeing to dismantle, the parts of two interference fit separate gradually.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete accompanying drawing.
As shown in Figure 1: the utility model comprises first parts 1 and second parts 2, is respectively equipped with tapped hole at first parts 1 and second parts 2, and first parts 1 are connected with second parts 2 by tapped hole, stud bolt body 3; Bottom at the tapped hole of described first parts 1 is provided with the through hole that is communicated with this tapped hole, installs when being connected at first parts 1 and second parts 2, and this through hole can be used as the use of inner hexagon spanner 4;
Described stud bolt body 3 is interior hexagonal stud bolt, is equipped with screw thread at the two ends of stud bolt body 3, and the nominal diameter of two ends screw thread can be the same or different, and the pitch of threaded one end is greater than the pitch of the other end screw thread.By the different pitch of stud bolt body 3 two ends screw threads, the part of first parts 1 and second parts, 2 interference fit is cooperated easily and separate.
Working procedure of the present utility model: during use, earlier stud bolt body 3 is screwed in the tapped hole of first parts 1, till can not screwing in; Re-use spanner 4, being threaded in the tapped hole on second parts 2 of stud bolt body 3 the other ends; Because the pitch of stud bolt body 3 two ends screw threads is different, so first parts 1 and second parts 2 are close gradually, combines closely until first parts 1 and second parts 2.During dismounting, in like manner, because the pitch of stud bolt body 3 two ends screw threads is different, so first parts 1 separate gradually with second parts 2.
Claims (2)
1. stud bolt linkage structure, comprise first parts (1) and second parts (2), be respectively equipped with tapped hole at first parts (1) and second parts (2), first parts (1) are connected with second parts (2) by tapped hole, stud bolt body (3); It is characterized in that: the two ends at described stud bolt body (3) are equipped with screw thread, and the pitch of threaded one end is greater than the pitch of the other end screw thread.
As power require 1 described stud bolt linkage structure, it is characterized in that: the bottom at the tapped hole of described first parts (1) is provided with the through hole that is communicated with this tapped hole.
