Abstract
The invention discloses a pretensioning device for fixing a first part and a second part and comprising a screw. The first part and the second part are provided with screw holes corresponding to each other. One end of the screw is a threaded connecting end, and a nut is arranged at the other end of the screw. The threaded connecting end of the screw penetrates the screw hole of the second part and the screw hole of the first part sequentially. A disc spring is sleeved on the screw and disposed between the second part and the nut. The pretensioning device can provide a pretensioning force to fix the two parts.
Description
Technical field
The present invention relates to a kind of pre-tightening apparatus.
Background technique
In mechanical field, linkage structure problem is important problem of product specification middle cover.Each functional part that forms product need to be connected and fixed in every way and form integral body, to complete the design function of product, the product casing that meets form-making design, is also comprised of parts such as bottom, main body frames conventionally, need to be connected and fixed and form an integral body.And the current mode that is fixedly connected with major part is adopted and is screwed, only adopt the fixing poor effect of screw, originally two fixing parts are easily in movement process, produce friction, once produce friction between two parts, can make both surface of contact impaired, then make to produce and slide between two parts.
Summary of the invention
For overcoming above-mentioned shortcoming, the object of the present invention is to provide a kind of energy to the pre-tightening apparatus that pretightening force is fixedly provided of two parts.
In order to reach above object, the technical solution used in the present invention is: a kind of pre-tightening apparatus, in order to fix the first part and the second part, it comprises screw, described the first part with on the second part, be respectively arranged with mutual corresponding screw, one end of described screw is threaded ends, the other end of described screw has nut, the threaded ends of described screw passes the screw of described the second part successively, the screw of the first part, on described screw, be arranged with dish spring, described dish spring is between the second part and nut.
Preferably, be also arranged with pad on described screw, described pad is between described dish spring and the second part.
Owing to having adopted technique scheme, be not difficult to find out beneficial effect of the present invention: by be arranged with dish spring on screw, dish spring is between the second part and nut, under the fixing prerequisite of screw, dish spring provides pretightening force to the first part and the second part, and two fixing parts are easily in movement process, even if produce friction between two parts originally, surface of contact is impaired, and this pretightening force can also be fixed the first part and the second part.
Accompanying drawing explanation
Fig. 1 is the sectional view of this pre-tightening apparatus.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
As shown in Figure 1, the invention provides a kind of pre-tightening apparatus, in order to fix the first part 1 and the second part 2, it comprises screw, and the first part 1 is respectively arranged with mutual corresponding screw with on the second part 2, and one end of screw is threaded ends, the other end of screw has nut, the threaded ends of screw passes the screw of the second part 2 successively, the screw of the first part 1 is arranged with dish spring 4 on screw, and dish spring 4 is between the second part 2 and nut.By be arranged with dish spring 4 on screw, dish spring 4 is between the second part 2 and nut, under the fixing prerequisite of screw, dish spring 4 provides pretightening force to the first part 1 and the second part 2, originally two fixing parts are easily in movement process, even if produce friction between two parts, surface of contact is impaired, and this pretightening force can also be fixed the first part 1 and the second part 2.
On screw, be also arranged with pad 3, pad 3 is between dish spring 4 and the second part 2.
Above mode of execution is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art understand content of the present invention and implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (2)
1. a pre-tightening apparatus, in order to fix the first part and the second part, comprise screw, described the first part with on the second part, be respectively arranged with mutual corresponding screw, one end of described screw is threaded ends, and the other end of described screw has nut, and the threaded ends of described screw passes the screw of described the second part successively, the screw of the first part, it is characterized in that: on described screw, be arranged with dish spring, described dish spring is between the second part and nut.
2. pre-tightening apparatus according to claim 1, is characterized in that: on described screw, be also arranged with pad, described pad is between described dish spring and the second part.
