Abstract
The utility model relates to a bolt, comprising a head part and a rob part with a screw thread. The utility model is characterized in that the head part is provided with a through hole vertical with the axis of the rob part, and the front end of the rob part can be designed into an ejector pin structure. Compared with the prior art, the utility model has the advantages that as the top part of the bolt is additionally provided with the through hole, the bolt can be rapidly inserted into a corresponding instrument, and therefore the test work of the part can be conveniently completed; at the same time, recurring to the ejector pin structure of the front end of the rob part, the bolt plays the role of positioning and locking in the process of screwing in. The bolt reaches the purpose of fastening, and at the same time the bolt has other auxiliary functions, so the bolt can greatly meet the use requirements of special occasions.
Description
Technical field
The utility model relates to a kind of bolt of fastening usefulness.
Background technique
Bolt is a kind of fastening piece commonly used, and standard bolt is made up of head and screwed bar portion, during use, is threaded mutually with corresponding nut or tapped hole, can reach the purpose of fastening two parts.But, on the joint shaft bearing as roll squeezer, behind fastening two parts, also require in time to know some information (as requirements such as moments), so that take appropriate measures at this fastening position at some special occasions.And this moment, if the bolt of the standard of employing just can't make things convenient for test.Some occasions are also arranged, in bolt screw-in process, require bolt can have locking and locating function.But standard bolt also can't reach above-mentioned specific (special) requirements.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of fastening purpose that can realize at above-mentioned prior art present situation, can test the bolt of providing convenience for moment again.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: this bolt comprises head and screwed bar portion, it is characterized in that: have the perpendicular through hole of axis with described bar portion on the described head.
As further improvement of the utility model, the front end of described bar portion can be designed to thimble structure, utilizes this thimble like this, can make this bolt in the screw-in process, plays the location, the locking effect.
As another kind of improvement the of the present utility model, between described thimble and screw thread, also have the transiting rod that the cross section is square, can sheathed part on this square transiting rod, so that rotating with bolt, this part reaches desired area.
Compared with prior art, because head of the present utility model has been set up a through hole, thereby can plant fast for corresponding instrument, thereby can finish the test job at this position easily; Can screw in process at bolt by means of the thimble structure of bar portion front end simultaneously, can play location, locking effect thereupon.So the utility model is reaching the miscellaneous function that fastening purpose also has other simultaneously, therefore can satisfy the usage requirement of some special occasions preferably.

Fig. 2 is the plan view of Fig. 1;
Fig. 3 is the sectional view of A-A line among Fig. 1.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, this bolt comprises head 1 and screwed bar portion 2, wherein, has the through hole 3 perpendicular with the axis of bar portion on the head of bolt, the Front-end Design of bar portion becomes thimble 4 structures, also has the transiting rod 5 that the cross section is square between this thimble and screw thread.
During use, the screw thread of this bolt is threaded mutually with the respective threads hole, rotates the purpose that this bolt can reach fastenings.By means of the through hole of bolt head, can carry out the moment test simultaneously.Utilize the thimble of bar portion front end, can play location, locking effect.Thereby the utlity model has stronger practicability.
