Abstract
The invention relates to an anti-loosening fastener. The anti-loosening fastener comprises a bolt, a nut, a pressing cover and a locking screw, wherein an internal thread hole is formed at the end of the bolt; the internal thread direction of the internal thread hole is opposite to the external thread direction of the bolt; during the joint of the bolt and the nut, the end of the bolt does not extend out of the outer end face of the nut; a hole is formed in the center of the pressing cover; and the locking screw penetrates through the hole in the center of the pressing cover and then is matched with the internal thread hole at the end of the bolt.
Description
Technical field
The invention belongs to firm field, refer to especially a kind of be used to larger load being arranged or the fastener of frequent vibration environment being arranged.
Background technique
Bolt connecting mode is simple to operate because of it, and is applicable to repeated multiple times dismounting, has obtained using very widely.But this interconnection technique also has certain defective, is exactly that nut in concussion place repeatedly of height, high load easily produces loosening.This technical barrier is that those skilled in the art are difficult to overcome always.
Although more existing anti-loosening modes are all processing and operating difficulties.As use the mode of nut pad, and be to use many technological schemes in this respect, the nut pad of employing is that rubber or resin finishing form, and is difficult to bear large concussion repeatedly, also can't be applicable to repeated multiple times dismounting or installation.Other mode and method also exist certain problem.
Summary of the invention
The purpose of this invention is to provide a kind of novel fastener, it is locking effective, is easy to installation and removal.
The present invention is achieved by the following technical solutions:
A kind of locking firm, include screw bolt and nut; End at bolt is provided with interior threaded hole, and the internal thread direction in described interior threaded hole is with bolt outside thread opposite direction; When bolts and nuts engaged, the end of bolt did not exceed the exterior edge face of nut; Described fastening piece also includes the porose gland of center band and lock screw, and the interior threaded hole that described lock screw passes after the center hole of gland with the bolt end matches.
Described gland is provided with circular protrusions take the gland center as the center of circle.
The diameter of described gland is greater than the internal diameter of the nut external diameter less than nut.
The beneficial effect that the present invention compares with prior art is:
When nut had been subject to repeatedly impact and loosening power occurs, at this moment the screw thread of the lock screw of gland center will apply one with the opposite power of the power of loose nut to lock screw because opposite with the outside thread of bolt, has stoped the loosening of nut.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below by specific embodiment, technological scheme of the present invention is described, following examples are just in order to illustrate the present invention rather than to limit scope of the present invention.
A kind of locking firm, include bolt 1 and nut 2; Be provided with interior threaded hole 5 in the end of bolt, the internal thread direction in described interior threaded hole 5 is with bolt outside thread opposite direction; When bolt 1 engaged with nut 3, the end of bolt 1 did not exceed the exterior edge face of nut 2; Described fastening piece also includes center band porose gland 3 and lock screw 4, and the interior threaded hole 5 that described lock screw 4 passes after the center hole of gland 3 with bolt 1 end matches.
Described gland is provided with circular protrusions take the gland center as the center of circle, and this protruding purpose is in order to reduce the outstanding of lock screw.
The diameter of described gland is greater than the internal diameter of the nut external diameter less than nut.
Above embodiment has illustrated technological scheme of the present invention, it will be appreciated by those skilled in the art that and can is out of shape or is equal to replacement by above-mentioned technological scheme, all can access other embodiments of the invention.
