Abstract

The utility model discloses a loose preventing screw bolt. When shake occurs to the mechanical equipment, the prior screw bolt may become loose and the nut might debuckle, which brings about hidden troubles. The newly disclosed loose preventing screw bolt is connected in turn and sequence by a gutter type screw bolt, a loose preventing thimble, a spring pad and a saw-tooth type nut. When intensive shaking occurs to the machine, the device that can help prevent the objects from being loosed is made with a simple structure.

Description

Chek bolt

Technical field

The utility model relates to the chek bolt that a kind of machinery is connected and fixed usefulness.

Background technique

Being connected and fixed of machinery is diversified, and being connected and fixed with bolt is wherein a kind of.In order to allow equipment well connect, also different on the structure of fixing bolt, there is closely-pitched locking, there have clamp nut to add cotter pin to be locking, has the spring pad of adding locking etc., desirable not enough on application in practice, especially the machinery of strenuous vibration is obvious especially, main cause is that mechanical strenuous vibration causes bolt looseness, and nut moves back button, has hidden danger.

Summary of the invention

The utility model has overcome the deficiencies in the prior art, provides a kind of when the machinery strenuous vibration, and bolt is loosening to some extent and nut does not move back the chek bolt of buckleing.

In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals: with two parts that will fix with grooved bolt string together, add spring pad after putting locking sleeve pipe, tighten the sawtooth pattern nut again.

On the nuts of described grooved bolt gap is arranged; Described locking sleeve pipe one end has projection, and the other end has the plane vertical with locking sleeve pipe, and a plurality of sawtooth pattern angles are arranged on the plane, and its angle direction is opposite with the hand of spiral of grooved bolt; Described spring pad is corresponding with the angle on the locking sleeve pipe; There are a plurality of angles on a plane of described sawtooth pattern nut, and its angle direction is opposite with the hand of spiral of grooved bolt.

Because adopt technique scheme, the chek bolt that the utility model provides has such safety reliability, when equipment shake, bolt became flexible to some extent and nut can not move back and buckles, and reached anti-loosing effect.Simple in structure.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail: the hole of two parts that will fix 5 is aligned, from top to bottom, put on grooved bolt 1, be enclosed within locking sleeve pipe 4 on the bolt shank from top to bottom, spring pad 3 is enclosed within on the bolt shank, and the sawtooth pattern of screwing at last nut 2 gets final product.

On the nuts of grooved bolt 1 of the present utility model gap is arranged, one end of locking sleeve pipe 4 has projection, the other end has the plane vertical with locking sleeve pipe 4, a plurality of sawtooth pattern angles are arranged on the plane, gap on the projection of locking sleeve pipe 4 and grooved bolt 1 nuts aligns, an end of spring pad 3 and the sawtooth pattern angle interlock on the locking sleeve pipe 4; Sawtooth pattern angle interlock on the other end and the sawtooth pattern nut 2.

Claims

1, a kind of chek bolt comprises bolt, nut, spring pad, it is characterized in that: grooved bolt, locking sleeve pipe, spring pad, sawtooth pattern nut connect in order successively.

2, chek bolt according to claim 1 is characterized in that: on the nuts of grooved bolt gap is arranged.

3, chek bolt according to claim 1 is characterized in that: an end of locking sleeve pipe has projection, and the other end has the plane vertical with locking sleeve pipe, and the sawtooth pattern angle is arranged on the plane.
