Abstract
The utility model provides a loosening-preventive bolt component, and can thoroughly solve the problem of screw loosening and can prevent loosening of a screw under the condition of extremely strong acting force without being limited by outside temperature, vibration and the like. The loosening-preventive bolt component comprises a bolt and a nut connected with the bolt through a thread, the bolt comprises a screw and a bolt head integrally formed with one end of the screw, two C-shaped holes parallel to the axis of the screw are arranged at the other end of the screw, an internal thread is arranged on each C-shaped hole, a loosening-preventive screw is screwed in each C-shaped hole, the two loosening-preventive screws are connected integrally through a strap-shaped body, and the nut and the C-shaped holes are opposite in thread spiral direction.
Description
Technical field
The present invention relates to a kind of subassembly of lock bolt, be specifically related to a kind of subassembly of lock bolt.
Background technique
Current screw is comprised of screw bolt and nut conventionally.Due to the loosening of screw and the accident that causes of coming off of common occurrence.Although current anti-loose method has played certain anti-loosing effect, all there is different defects, the problem that can not thoroughly solve loosened screw and come off.
Summary of the invention
The object of the invention is to provide a kind of subassembly of lock bolt, can thoroughly solve loosened screw problem, prevents bolt looseness and be not subject to the restrictions such as outer temperature, vibrations the in the situation that of extremely strong active force.
To achieve these goals, the present invention is by the following technical solutions:
A kind of subassembly of lock bolt, comprise bolt and the nut being threaded connection with bolt, bolt comprise screw rod and with screw rod one end all-in-one-piece bolt head, the screw rod the other end is provided with two C shape holes parallel with screw axis, each C shape hole is provided with internal thread, and in each C shape hole, be combined with anti-loosening screw, two anti-loosening screws connect as one through shoestring, and nut is contrary with the thread rotary orientation in C shape hole.
Preferably, two C shape holes are symmetrical about screw axis.
Preferably, two C Xing Kong centers and screw rod center are on same straight line.
Preferably, the arc length in each C shape hole 2 is greater than 1/2 of its circumference.
Preferably, between two C Xing Kong centers, distance is less than screw diameter.
Beneficial effect of the present invention:
By the mutual restriction of each parts, can bolt is thoroughly locked, in the situations such as vibrations, high temperature, time length, be not subject to be affected yet.。

Embodiment
For the ease of those skilled in the art, understand, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
A kind of subassembly of lock bolt, comprise bolt 1 and the nut 4 being threaded connection with bolt 1, bolt 1 comprise screw rod 102 and with screw rod 102 one end all-in-one-piece bolt heads 101, screw rod 102 the other ends are provided with two C shape holes 2 parallel with screw rod 102 axis, each C shape hole 2 is provided with internal thread 3, and in each C shape hole 2, be combined with anti-loosening screw 5, two anti-loosening screws 5 and connect as one through shoestring 6, nut 4 is contrary with the thread rotary orientation in C shape hole 2.
Two 2 centers, C shape hole and screw rod 2 centers are on same straight line, and two C shape holes 2 are symmetrical about screw rod 102 axis, and between 2 centers, two C shape holes, distance is less than screw rod 102 diameters, and the arc length in C shape hole 2 is greater than 1/2 of its circumference.
Working process: make C shape hole 2 on bolt 1, its number is not less than 2; And make the anti-loosening screw 5 matching with it, anti-loosening screw 5 screws in behind C shape hole 2, can protrude from bolt 1 circumferential surface, to stop that nut 4 retreats; Anti-loosening screw 5 connects as one through shoestring 6, and tensioning.
Movement process: because the sense of rotation that nut 4 advances is contrary with the sense of rotation that anti-loosening screw 5 advances, if withdrawn the membership after nut 4, anti-loosening screw 5 is produced to frictional force, the power that this frictional force can be advanced as anti-loosening screw 5, thus more effective restriction, stop nut 2 to retreat.If one retreats in anti-loosening screw 5, by shoestring 6, power is passed to another anti-loosening screw 5, the power that can advance as another anti-loosening screw 5, simultaneously another anti-loosening screw 5 advances and is subject to the prevention of nut 2 and cannot advances, thereby guarantees that two anti-loosening screws 5 all cannot retreat.
Using method:
One, installation method: (1) is arranged on nut 4 on bolt 1, and screws; (2), anti-loosening screw 5 is arranged on C shape hole 2 and is screwed; Shoestring 6 is connected on anti-loosening screw 5 and tensioning.
Two, method for dismounting: (1) takes off shoestring 6; (2) rotation anti-loosening screw 5 makes it exit C shape hole 2; (3) rotating nut 2 retreats until separated with bolt 1.
Above embodiment is only for illustrating that technological scheme of the present invention is not intended to limit; although the present invention is had been described in detail by embodiment; affiliated field personnel should modify or part technical characteristics is equal to replacement with reference to concrete mode of the present invention; but do not departing under the spirit of technical solution of the present invention above-mentioned change or be equal to replacement and should belong in the technological scheme scope that the present invention asks for protection.
