Quick-dismantle component 500 is additionally provided with abrasive machine containment envelope, it includes handle 501, to lock threaded rod 505 and to lock spiral shell
Mother 506, the end of handle 501 and one end to lock threaded rod 505 are fixed together, to one of lock threaded rod 505 away from handle 501
End is provided with screw thread, can be screwed in in split nut 506, corresponding to be, split nut is fixed on inner cap 200, its fixed bit
Putting ensures after inner cap 200 and the fastening of enclosing cover 100, to be inserted into the screwed hole to split nut 506 lock threaded rod 505,
Also, the front end for locking threaded rod 505 will be directly riveted on in split nut 506, as shown in fig. 1, having to split nut 506
One end of screwed hole is located in the cyclic structure of space collar 300 towards enclosing cover 100 to the screwed end of lock threaded rod 505,
I.e. towards inner cap 200, after inner cap 200 is fastened on space collar 300, lock threaded rod 505 is narrowly focused towards to split nut 506
Screwed hole at, hereafter, by rotate handle 501 cause to lock the synchronous rotary of threaded rod 505 so as to lock threaded rod
505 precessions are in split nut 506, inner cap 200 and enclosing cover 100, space collar 300 are tightened together.The preferred eccentric hand of handle 501
Handle.
In order that can be fast and accurately buckled together when obtaining inner cap 200 and space collar 300, the fastening of enclosing cover 100, in inner cap
200 and space collar 300 on set and fasten object of reference, as shown in fig. 1, closed orientation salient point 600 is set on inner cap 200, with
This positioning convex point is corresponding to be, the orientation triangle groove 301 of equal number is set on space collar 300, is fastened on by inner cap 200
, can be using the engaging with orientation triangle groove 301 of closed orientation salient point 600 as benchmark, when the two is fastened on one when on space collar 300
When rising, it is meant that inner cap 200 and space collar 300 are exactly in alignment, hereafter operating personnel just rotatable handles 501, make
Lock threaded rod 505 must be screwed into in split nut 506, inner cap 200 is fixed on space collar 300, it is a kind of quick-detachable
Abrasive disc machine shield just can fence up the emery wheel of abrasive machine.
The structure chart of Quick-dismantle component 500 as shown in Fig. 2 in fig. 2, handle 501 with it is substantially perpendicular to lock threaded rod 505
Shape is fixed together, and is easy to rotary handle 501 when in use, will be secured to be connected to be screwed into lock lock threaded rod 505
In nut 506, implement locking.In order to further improve the stability that Quick-dismantle component 500 is installed and used, to lock threaded rod 505
On be also arranged with buffering spacer 502, spring shim 503 and locating shim 504 successively, buffering spacer 502 is located to lock threaded rod
505 close to the end of handle 501, coordinate spring shim 503 and buffering spacer 502, and one is prevented from falling lock threaded rod 505
Move back and come off from enclosing cover 100, two too deep are difficult to back-out to be also possible to prevent to be screwed into lock threaded rod 505 in split nut 506.
Fig. 3 is the structural representation to split nut 506 in Quick-dismantle component 500, as illustrated, its one end is nut, separately
One end is provided with screwed hole, for being screwed into lock threaded rod 505 front end, the depth of screwed hole and its internal reach with to lock
Externally threaded length on threaded rod 505 is adapted.
Fig. 4 is a kind of local structural graph of the inner cap 200 of quick-detachable abrasive disc machine shield of the present invention, with the side of facing
Position viewing, closed orientation salient point 600 is provided with the edge of inner cap 200, and closed orientation salient point 600 protrudes the surface of inner cap 200,
Polyhedral can be arranged to, closed orientation salient point 600 can set multiple, its quantity will be with the orientation triangle groove on space collar
301 quantity correspondence, is easy to the two to agree with.
Fig. 5 shows for the partial structurtes of the cross section on a kind of space collar of quick-detachable abrasive disc machine shield of the present invention
It is intended to, as illustrated, setting multiple orientation triangle grooves 301 in the edge of space collar 300, orientation triangle groove 301 is space collar
300 edge is inwardly shunk in triangular shape to be formed, and the distribution of orientation triangle groove 301 is convex with the closed orientation on inner cap 200
The position of point 600 is corresponding, and its cross-sectional area for shrinking formed space is larger than the horizontal stroke of closed orientation salient point 600
Sectional area so that closed orientation salient point 600 can be inserted into orientation triangle groove 301.As depicted, can also be in space collar
An orientation triangle groove 301 is opened up with to the corresponding position of split nut 506 on 300, is opened up in orientation triangle groove 301 in this place
One fixing hole 302, when opening up fixing hole 302 can directly punch process form so as to lock threaded rod 505 therefrom wear
Cross, for fixed to lock threaded rod 505.The diameter of fixing hole 302 is slightly larger than the diameter to locking threaded rod 505, in assembling, first
Lock threaded rod 505 will be passed through from fixing hole 302, cover buffering spacer 502, bullet successively on to lock threaded rod 505 afterwards
Spring pad 503 and locating shim 504.Certainly, in the present invention, the position of fixing hole 302 can enter line translation, and it can
To be arranged on the other positions of space collar 300, as long as can make it that it is combined with to split nut 506.
The assembling of Quick-dismantle component 500 is after being fixed to split nut 506 on inner cap 200, to lock with 505 Duis to lock threaded rod
(will to lock threaded rod 505 be screwed into in split nut 506), hereafter will to carrying out riveting side processing at the front opening of split nut 506,
So that no longer being disengaged to lock threaded rod 505 and to split nut 506, and to the size requirement for locking threaded rod 505 done outside at screw thread
Footpath is greater than at non-threaded), when dismantling emery wheel, only Quick-dismantle component 500 need to be unclamped and up carried, integral enclosing cover can be because drawing
Power is automatically opened up, and can conveniently be dismantled and be installed emery wheel, when emery wheel installation, only need to close integral enclosing cover, and by Quick Release group
Part 500 is depressed at correct position and locked by handle 501.
In the present invention, space collar 300 and enclosing cover 100 can be made monolithic.
Above in conjunction with accompanying drawing to the present invention embodiment be explained in detail, but the present invention be not limited to it is above-mentioned
Embodiment, can also be on the premise of present inventive concept not be departed from the knowledge that those skilled in the art possess
Make a variety of changes.
