(3) during Bolt dismantling, the separation of equipment and housing construction, by screen resilience, spring ejects bolt, to operator
Member is made operating personnel know to have dismantled and finish, is not required to visually observe with touch feedback, very convenient.
On the basis of above-mentioned technical proposal, the utility model can also do following improvement.
Further, including in the stop collar and positioning sleeve and bolt of integrative-structure, the positioning sleeve is hollow cylinder
Structure, the front end of the positioning sleeve is provided with minor diameter inserted terminal, and rear end and the front portion of the stop collar are in integrally connected, described
Form spacing cavity in stop collar, the stop collar rear portion is provided with screwdriver jack, the end of thread of the bolt is inserted into described
In positioning sleeve, screw cap end is located in the spacing cavity, and spring is provided between the nut and positioning sleeve;The screwdriver is inserted
The diameter in hole is less than the diameter of the nut.
The beneficial effects of the utility model are:(1) because stop collar and positioning sleeve are in integrative-structure, so installing, tearing open
Coming off for bolt is cannot be easily caused during unloading, it is easy to the management of fastenings;
(2) in equipment and housing construction connection procedure, by minor diameter inserted terminal, connecting bolt is in equipment mounting hole
Can positioning, efficiency raising when bolt external screw thread is connected with structure internal screw line.
(3) during Bolt dismantling, the separation of equipment and housing construction, by screen resilience, spring ejects bolt, to operator
Member is made operating personnel know to have dismantled and finish, is not required to visually observe with touch feedback, very convenient.
Further, the rear end of the positioning sleeve is provided with the step being connected as a single entity, and the stop collar is filled by rolling technology
On the step for fitting over the positioning sleeve;
Further, the stop collar is threadedly coupled with the positioning sleeve
The beneficial effects of the utility model are:Step forms spacing cavity in stop collar, controls the size of spacing cavity,
So as to play the elastic deformation of control spring, for spring positioning.
Further, the shoulder 7 of evagination is provided between the step and the minor diameter inserted terminal.
The beneficial effects of the utility model are:In dismounting due to the presence of shoulder, barrier dismantling spanner and equipment are direct
Collision, the damage that protection equipment collision belt comes.
