Vibrations, rotation, impact and inevitable all kinds of mechanical factors, the time is permanent, will necessarily cause the loosening of fastener in equipment,
If without finding in time, it is possible to great loss is brought to field apparatus or personnel, is caused to site safety production tight
The hidden danger of weight.The fastening used in an installation for equipment domestic at present and the fastening of all kinds of steel and iron parts are bolt classes, substantially
On reach shockproof and locking purpose in the form of all kinds of bolt+spring washers.But in the severe work of some operating modes
In place and the longer engineering of capital construction battle line, using the form of bolt+spring washer come the shockproof anti-loosing effect of fastener fixed
It is undesirable, at the same the fastener to having loosened also can not and time point inspection find, cause a hidden trouble, and bring to site safety production
Heavy losses.
【Utility model content】
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of interior tensioner spring bolt, can
Make bolt during tightening, without matching spring washer in addition, voluntarily by spring-compressed tensioner, so as to prevent bolt from beating
Cunning moves back silk, simple and practical, beneficial to popularization and application.
To achieve the above object, the utility model proposes a kind of interior tensioner spring bolt, including bolt head, shank of bolt,
Holding tank, tensioner spring, position guiding groove, tensioner bullet, lead a side plate, the bolt head, shank of bolt are integral type structure, the spiral shell
Tightening latch is arranged on the bottom of bolt head straight down, and the holding tank is arranged on the bottom of shank of bolt, the opening of the holding tank
Straight down, the side of the holding tank is provided with some position guiding grooves, and the tensioner spring and tensioner bullet are integral type structure,
The tensioner spring is arranged in holding tank, the side of the tensioner bullet be provided with it is some lead a side plate, it is described to lead a side plate
It is connected in position guiding groove.
Preferably, being provided with adsorption magnet at the top of the holding tank, the top of the tensioner spring is provided with down
Adsorption magnet, the upper adsorption magnet and lower adsorption magnet are by together with magnetic-adsorption, the maximum elongation of the tensioner spring
Distance is 3/4ths of receiving groove depth.
Preferably, the quantity of the position guiding groove at least two, the position guiding groove is circumferentially positioned at holding tank vertically
In side wall, the length of the position guiding groove is to accommodate the half of groove depth, the length of the position guiding groove and the length of tensioner bullet
Spend identical.
Preferably, the quantity for leading a side plate at least two, a side plate of leading is circumferentially positioned at tensioner vertically
The side of bullet, the bottom shape of the tensioner bullet is smooth hemispherical.
The beneficial effects of the utility model：The utility model by by bolt head, shank of bolt, holding tank, tensioner spring, lead
Position groove, tensioner bullet, lead a side plate and be combined together, by optimum experimental, bolt can be made during tightening, without another
Outer matching spring washer, it is simple and practical so as to prevent bolt skids from moving back silk voluntarily by spring-compressed tensioner, beneficial to pushing away
Wide application.
Feature and advantage of the present utility model will be described in detail by embodiment combination accompanying drawing.
