Specific embodiment
Purpose, technical scheme and advantage for making the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is explicitly described it is clear that described embodiment is the present invention
A part of embodiment, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not having
The every other embodiment being obtained under the premise of making creative work, broadly falls into the scope of protection of the invention.
As shown in Figure 1, abrasive machine containment envelope, on the emery wheel being enclosed within abrasive machine when using, emery wheel is entangled, including
Enclosing cover 100, inner cap 200 and space collar 300, enclosing cover 100 and inner cap 200 are preferably disc-shaped, and space collar 300 is located at enclosing cover 100
And inner cap 200 between, the diameter of the diameter of space collar 300 and enclosing cover 100 is adapted so that can around space collar 300
It is fixed on the edge of enclosing cover 100, afterwards inner cap 200 is buckled on space collar 300；Set between inner cap 200 and space collar 300
Put a hinge 400, hinged by hinge 400, that realizes folding stirs action.
As shown in Figure 1, enclosing cover 100 and inner cap 200 and space collar 300 are provided with opening, by abrasive machine
After shielding cover is contained on abrasive machine, the emery wheel of abrasive machine some exposed by the opening on abrasive disc machine shield it is ensured that
The high speed rotational operation of emery wheel.
Quick-dismantle component 500 is additionally provided with abrasive machine containment envelope, it includes handle 501, to lock threaded rod 505 with to lock spiral shell
Female 506, handle 501 end and one end of lock threaded rod 505 is fixed together, to lock threaded rod 505 away from the one of handle 501
End is provided with screw thread, can be screwed in in split nut 506, corresponding is split nut to be fixed on inner cap 200, its fixed bit
Put and guarantee, after inner cap 200 and enclosing cover 100 fasten, to be inserted into the screw thread in the hole to split nut 506 to lock threaded rod 505,
As shown in fig. 1, there is one end of screwed hole to split nut 506 towards enclosing cover 100, to the lock screwed end of threaded rod 505
Portion is located in the circulus of space collar 300, that is, towards inner cap 200, after inner cap 200 is fastened on space collar 300, to lock
Threaded rod 505 is narrowly focused towards at the screwed hole to split nut 506, hereafter, is made to lock threaded rod 505 by turning handle 501
Synchronous rotary, so as to lock threaded rod 505 precession in split nut 506, by inner cap 200 and enclosing cover 100, space collar 300
Tighten together.The preferred eccentric handle of handle 501.
So that inner cap 200 and space collar 300, enclosing cover 100 can fast and accurately be buckled together, in inner cap when fastening
200 and space collar 300 on setting fasten object of reference, as shown in fig. 1, on inner cap 200 arrange closed orientation salient point 600, with
This positioning convex point is corresponding to be, arranges the orientation triangle groove 301 of equal number, inner cap 200 is being fastened on space collar 300
When on space collar 300, can be using closed orientation salient point 600 engaging with orientation triangle groove 301 as benchmark, when the two is fastened on one
It is meant that inner cap 200 and space collar 300 are exactly in alignment when rising, hereafter operator 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, abrasive disc machine shield just may be used
So that the emery wheel of abrasive machine to be fenced up.
As shown in Fig. 2 in fig. 2, handle 501 is substantially perpendicular with to locking threaded rod 505 for the structure chart of Quick-dismantle component 500
Shape is fixed together, and is easy to rotary handle 501 when using, and will be secured to be connected to lock threaded rod 505 is screwed into lock
In nut 506, implement locking.In order to improve the stability that Quick-dismantle component 500 is installed and used further, to lock threaded rod 505
On be also arranged with buffering spacer 502, spring shim 503 and locating shim 504 successively, buffering spacer 502 be located to lock threaded rod
505 near the end of handle 501, coordinates spring shim 503 and buffering spacer 502, and one being prevented from lock threaded rod 505 is fallen
Move back and come off from enclosing cover 100, two are difficult to back-out very much to be also possible to prevent lock threaded rod 505 is screwed in split nut 506 deeply.
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 the local structural graph of the inner cap 200 of abrasive disc machine shield of the present invention, with the viewing of positive aspect, in inner cap 200
Edge be provided with closed orientation salient point 600, closed orientation salient point 600 protrudes the surface of inner cap 200, it can be provided polyhedron
Shape, closed orientation salient point 600 can arrange multiple, and its quantity is corresponding with the quantity of the orientation triangle groove 301 on space collar, just
Agree with the two.
Fig. 5 is the partial structural diagram of the cross section on the space collar of abrasive disc machine shield of the present invention, as illustrated,
The edge of space collar 300 arranges multiple orientation triangle grooves 301, and orientation triangle groove 301 is that the edge of space collar 300 is in inwardly
Triangular shape shrinks and forms, and the distribution of orientation triangle groove 301 is corresponding with the position of the closed orientation salient point 600 on inner cap 200,
And it shrinks the cross-sectional area in formed space and is larger than the cross-sectional area of closed orientation salient point 600 so that closure is fixed
Position salient point 600 can be inserted in orientation triangle groove 301.As depicted, can also be on space collar 300 and to split nut 506
Corresponding position opens up an orientation triangle groove 301, opens up a fixing hole 302, open up in orientation triangle groove 301 in this place
Can directly punch process form so that extending there through to lock threaded rod 505, for fixing to lock screw thread during fixing hole 302
Bar 505.The diameter of fixing hole 302 is slightly larger than the diameter to lock threaded rod 505, in assembling, first will be to lock threaded rod 505 from solid
Determine to pass through in hole 302, cover buffering spacer 502, spring shim 503 and locating shim successively on to lock threaded rod 505 afterwards
504.Certainly, in the present invention, line translation can be entered in the position of fixing hole 302, and it can be arranged on space collar 300
Other positions, as long as can make it be combined with to split nut 506.
The assembling of Quick Release group 500 be to split nut 506 on inner cap 200 fixing after, and to lock threaded rod 505 to lock (i.e.
Lock threaded rod 505 will be screwed into in split nut 506), hereafter will carry out the process of riveting side at split nut 506 front opening, make
Must no longer disengage to lock threaded rod 505 with to split nut 506, and the dimensional requirement to lock threaded rod 505 is to do external diameter at screw thread
Greater than at non-threaded), when dismantling emery wheel, only Quick Release group 500 need to be unclamped and up carry, one enclosing cover can because of gravitation certainly
Move and open, can conveniently dismantle and emery wheel is installed, when emery wheel installation, only need to close one enclosing cover, and by under Quick Release group 500
It is pressed onto at correct position and carry out locking by handle 501.
In the present invention, space collar 300 and enclosing cover 100 can be made monolithic.
Above in conjunction with accompanying drawing, the specific embodiment of the present invention is explained in detail, but the present invention be not limited to above-mentioned
Embodiment, in the ken that those skilled in the art possess, can also be on the premise of without departing from present inventive concept
Make a variety of changes.
