Description
【Technical field】
This utility model is related to the technical field of Hardware fitting, particularly a kind of check bolt.
【Background technology】
Bolt is a kind of conventional securing member.Bolt is generally played with the screwed hole cooperation on nut or machine and is connected fastening
The effect of parts, although common bolt, nut connecting component have the advantages that simple structure, easy to use, there is also
, there is potential safety hazard in the deficiency for easily loosening, particularly when the parts that it is connected be chronically at vibratory shock load compared with
It is big and frequently working environment when, the fastening effect between bolt, nut connecting component is deteriorated, it is possible to which bolt abjection spiral shell occurs
The phenomenon of pit, it is impossible to be enough prevented effectively from the loosening of bolt, have impact on the service behaviour and stability of plant equipment, therefore propose
A kind of check bolt.
【Utility model content】
The purpose of this utility model is exactly to solve the problems of the prior art, it is proposed that a kind of check bolt, using push rod
With the cooperation of spring, during screwing bolts, push rod is moved up along chute, and anti-work is produced between push rod and bolt head
Firmly, the frictional force between the screw thread on bolt and connector can be increased, makes bolt connection more firm.
For achieving the above object, the utility model proposes a kind of check bolt, including bolt head, screw rod, spring, push rod
And baffle plate, screw rod is connected with below the bolt head, the screw rod is cylinder, and the periphery of the screw rod is provided with screw thread, institute
State and be provided with bolt head baffle plate, accommodating chamber is provided with below the baffle plate, spring is installed on the baffle plate, the screw rod it is upper
Side is provided with installation cavity, and the spring runs through installation cavity, and the spring is connected with push rod, and the both sides of the screw rod are provided with chute,
The chute is connected with installation cavity, and the push rod is inlaid in chute, opens up fluted below the bolt head, described recessed
Groove is engaged with push rod.
Preferably, the chute is shaped as rectangle, the width of the chute more than push rod width, the chute
Length is 1/3rd of spiro rod length.
Preferably, the groove is shaped as rectangle, the width of the groove more than push rod width, the groove
Height of the depth more than push rod.
Preferably, the cross sectional shape of the push rod is rectangle or circle, the length of the push rod is more than the external diameter of screw rod
Length.
The beneficial effects of the utility model：This utility model is matched somebody with somebody by bolt head, screw rod, spring, push rod and baffle plate etc.
Close, using the cooperation of push rod and spring, during screwing bolts, push rod is moved up along chute, push rod and bolt head
Between produce counteracting force, the frictional force between the screw thread on bolt and connector can be increased, prevent from shaking the loosening for causing
Phenomenon, makes bolt connection more firm.
Feature of the present utility model and advantage will combine accompanying drawing and be described in detail by embodiment.
