Abstract
A strengthening screw is composed of a screw rod and a nut. Threads on the screw rod are inclined notch threads. Three pawls are arranged on the nut. When the strengthening screw is used for fastening, the pawls is capable of clamping an inclined notch one time under effect of elastic force of a spring when the strengthening screw is screwed one time, and the strengthening screw is never loose. When the strengthening screw is screwed off by a person, the pawls are opened by a special tool, and the strengthening screw is screwed off as the ordinary screw. The strengthening screw is especially suitable for large scale equipment and fastening between parts placed at places where vibration is greatly violent.
Description
Affiliated technical field:
The present invention relates to a kind of fastening piece of main equipment, especially a kind of strong screw that tightens up for height vibration main equipment.
Background technique:
At present, tightening up between known main equipment parts is all to adopt traditional screw to tighten up, and in the king-sized place of vibration, the time one is long, and screw just becomes flexible; Expand with heat and contract with cold, the situation of loosened screw also can occur in time one length; When perhaps checking, do not find; Method commonly used adds a spring pad exactly below screw; Still happen occasionally but become flexible; Screw loosening, light device damage, heavy can cause a serious accident.
Summary of the invention:
In order to overcome existing screw in the deficiency aspect tightening up, the invention provides a kind of strong screw, it not only equally uses with normal screws in use, and after once tightening up, never becoming loose.(if the people must use special tool for unloading)
The technical solution adopted for the present invention to solve the technical problems is:
Because screw is comprised of two-part, screw rod, nut forms.Be shaped with oblique breach on screw flight, tiltedly breach just is equivalent to ratchet, and tiltedly breach just has one every 60 degree, and (or less than 60 degree) are equivalent to ratchet bar spirally on Cylinder.These oblique breach are evenly distributed on screw rod, form to have six oblique breach screw threads parallel with axis.It is oblique breach screw thread.On nut, be shaped with three ratchets, be mutually 120 and spend the angle, on each ratchet, spring is arranged, ratchet can be stuck on oblique breach under the elastic force of spring all the time.In fact be exactly the effect of ratchet on ratchet.With the method for routine, just can tighten up, but nut withdraws from loosening never again; If the people just uses special tool for unloading screw, the ratchet on nut is opened, equally unload with unloading plain nut.
The invention has the beneficial effects as follows:
Once tighten up never becoming loose, the generation of Accident prevention.
Description of drawings:
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is structural representation of the present invention
In figure, 1, screw rod, 2, oblique breach screw thread, 3, nut, 4, ratchet, 5, spring.
Embodiment:
On screw rod 1, just be shaped with an oblique breach screw thread 2 every 60 degree; Screw thread on screw rod 1 is exactly oblique breach screw thread 2; On nut 3, there are three to be mutually 120 ratchets 4 of spending the angle, a spring 5 is arranged on each ratchet 4.When nut 3 is enclosed within on screw rod 1, and when tightening up, often tightly once, the ratchet 4 on nut 1 will block oblique breach screw thread 2 once, plays the effect of ratchet.(if the people when unloading, must open ratchet with special tool)
Claims (1)
1. strong screw,, it is characterized in that: screw flight is oblique breach screw thread, three ratchets that are mutually 120 degree angles on nut.
