Description
Technical field
The present invention relates to a kind of service kit, especially a kind of maintenance spanner for having the function of to pre-install and recycle nut.
Background technology
Power electronic equipment is in production assembling and trouble shooting procedure, it is necessary to install or remove substantial amounts of bolt and nut.
Thus, at present in industry when carrying out power electronic product design, it is required for reserving larger behaviour to spanner and operative employee's arm
Make space.However, with the continuous development of power industry, the volume of power electronic equipment is less and less, and structure is also increasingly tighter
It gathers, is often present with the hidden link position of some narrow spaces and position.Operating personnel are installing or removing above-mentioned position
Because difficulty is larger during bolt and nut, the small parts such as bolt and nut can often be dropped.Production efficiency is so not only influenced, but also is set
Standby normal operation brings hidden danger.
At this stage, it is still that use reserves larger operating space or breaks the side of entire product from outside to inside in power industry
Formula, development progress but also the installation effectiveness for not only constraining facility compact are relatively low.And nut needs manually after having dismantled
Recycling, can not directly be recycled by overhauling spanner.
The content of the invention
The technical problem to be solved by the present invention is to：Overcoming the deficiencies of the prior art and provide one kind has prepackage and recycling spiral shell
The maintenance spanner of female function, production assembling and trouble hunting especially suitable for small space.
In order to achieve the above object, the technical scheme is that：A kind of maintenance for having the function of to pre-install and recycle nut

Property circle and movable contact block, the sleeve body, which is equipped with, axially receives hole and radial slippage hole, radial slippage hole and axially receives hole
Connection, movable contact block are connected with the sliding of radial slippage hole, and when elastic ring compressing activity contact block, movable contact block, which stretches into, to be axially received
In hole, the elastic ring is sleeved on sleeve body periphery, and the outer end of movable contact block passes through elastic ring /V.
Preferably, the operation lever includes handle portion and connecting portion, handle portion and connecting portion vertical connection, and is made one
Body, the sleeve body is equipped with mounting hole, and the connecting portion is equipped with the connecting pin with mounting hole cooperation, the connecting pin
It stretches into mounting hole, and passes through axis pin and be fixedly connected with sleeve body.
Preferably, there are three the movable contact block tools, there are three the slip hole of sleeve body also has, three movable contact blocks are equal
Cloth slides with corresponding slip hole connect respectively in sleeve body periphery.
Preferably, the slip hole of the sleeve body is stepped hole, and the outer end of movable contact block has positive stop lug boss.
Preferably, the radian of the outer end face of the movable contact block is consistent with sleeve body radian.
Preferably, there is chamfering between the inner face of the movable contact block and side.
Preferably, the movable contact block outer end face is equipped with elastic ring limiting slot, and the periphery of sleeve body also has /V
Slot, elastic ring are located in limiting slot and elastic ring limiting slot.
Preferably, the elastic ring has two, and the elastic ring limiting slot of movable contact block outer end face also has two.
Preferably, the hole that axially receives of the sleeve body is hex hole.
Preferably, the periphery of the sleeve body is equipped with annular installation arc groove.
With the above structure, the elastic ring moment of the invention is in compressive state, can be incited somebody to action by the elastic force of elastic ring
Movable contact block is withstood in sleeve body, and realization is reliably connected.During pre- assembly and disassembly nut, nut, which is put into, to be axially received in hole, is compeled
Make the open-top elastic ring of movable contact block, elastic ring further compressed, so as to elastic ring reaction force by movable contact block tightly
Nut surface is pressed in, nut is reliably fixed, and realizes the prepackage and recycling of nut.It is narrow and small that the present invention solves operating space
And the installation and repairing problem of the hidden junction in position, therefore be conducive to promote the close-coupled exploitation of product structure, so as to reduce
Equipment cost and occupation of land.

Specific embodiment
The present invention is described in further detail for the embodiment provided below in conjunction with attached drawing.
Referring to shown in Fig. 1,2,3, a kind of maintenance spanner for having the function of to pre-install and recycle nut including operation lever 1 and covers
Cartridge module 2, sleeve assembly 2 are connected in operation lever 1, and the sleeve assembly 2 includes sleeve body 3, elastic ring 4 and movable contact block
5, the sleeve body 3, which is equipped with, axially receives hole 31 and radial slippage hole 32, and sleeve body 3 axially receives hole 31 as hexagon
Hole, convenient that six-sided nut is mounted and dismounted, radial slippage hole 32 is connected with axially receiving hole 31, movable contact block 5 and
The sliding connection of radial slippage hole 32, when 4 compressing activity contact block 5 of elastic ring, movable contact block 5, which stretches into, to be axially received in hole 31, institute
It states elastic ring 4 and is sleeved on 3 periphery of sleeve body, and the outer end of movable contact block 5 passes through 4 /V of elastic ring.
Shown in Figure 3, the operation lever 1 includes handle portion 11 and connecting portion 12, and handle portion 11 is vertical with connecting portion 12
Connection, and be made it is integral, the sleeve body 3 be equipped with mounting hole 33, the connecting portion 12 be equipped with and mounting hole 33
The connecting pin 121 of cooperation, the connecting pin 121 are stretched into mounting hole 33, and are passed through axis pin 6 and be fixedly connected with sleeve body 3.By
It can be according to spiral shell in the hole 31 that axially receives in the different size model numbers that have of screw bolt and nut, the sleeve body 3 of sleeve assembly 2
The size model number of screw bolt and nut is different, various types of sleeve assemblies 2 is made, which can be more convenient by sleeve assembly
2 dismountings replace the sleeve assembly 2 of different model, improve installation and overhaul efficiency.
Referring to shown in Fig. 2 and 3, there are three activity contact block 5 tools, there are three the slip hole 32 of sleeve body 3 also has, three
A activity contact block 5 is distributed on 3 periphery of sleeve body, and slides connect with corresponding slip hole 32 respectively.Due to nuts and bolt
With for hexagon, movable contact block 5 sets at least three, and when mount and dismount six-sided nut, three activity contact blocks 5 can be with
It is against on different end faces, for preferably limiting nut.
Shown in Figure 3, the slip hole 32 of the sleeve body 3 is stepped hole, and the outer end of movable contact block 5 has /V
Boss 51.The radian of the outer end face of the activity contact block 5 is consistent with 3 radian of sleeve body.Using more than structure, live for /V
Dynamic contact block 5.Movable contact block 5 props up stepped hole by positive stop lug boss 51, also can not inboard end movement, and can only the open-top elasticity of stress
Circle 4 moves outward.
It is shown in Figure 3, there is chamfering between the inner face of the activity contact block 5 and side.Movable contact block 5 is in elastic ring
Under the action of 4, inner face, which stretches into, axially receives hole 31, when nut is needed into when axially receiving in hole 31, due to chamfering,
It can more smoothly enter and axially receive in hole 31, and open-top movable contact block 5.
Referring to shown in Fig. 2 and 3,5 outer end face of the activity contact block is equipped with elastic ring limiting slot 52, sleeve body 3 it is outer
