Flower, or because caused by improper use grinding wheel rupture splash phenomena, the harm that user is generated.Currently, angle frosted wheel cover
It is mainly fixed by locking wrench, user encounters the feelings that cutting angle needs to change during using angle grinder
When condition, need to carry out the change of wheel guard angle by following three steps: 1. unclamp locking wrench；2. rotating shroud；3. twisting
Tight locking wrench.Simultaneously for guarantee wheel guard locking stability, locking wrench is close-fitting, unclamp and rundown process need compared with
Big strength.
Summary of the invention
In order to improve the working efficiency of replacement angle frosted wheel cover angle, the utility model, which provides one kind and can quickly rotate, to be determined
The wheel guard of position.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of grinding wheel of the quick rotational positioning of energy
It covers, including grinding wheel cover main body, angle grinder front cover and front cover pressing plate, there is the sand connecting with the main body in the grinding wheel cover main body
Wheel cover axle journal is provided with flange on the wheel guard axle journal, there is threaded hole, U-lag and inner card cage, institute on the angle grinder front cover
It states and is provided with through-hole and U-lag on front cover pressing plate.
Wherein the front cover pressing plate through-hole corresponds to the threaded hole on the front cover, and is fastened on the front cover using screw
On, the front cover pressing plate plays position-limiting action, prevents shield from falling off.The wheel guard axle journal is by the flange by before described
The U-lag of lid pressing plate is installed under the front cover pressing plate, and is embedded in the front cover inner card cage.The front cover inner card cage assembly
There is multilayer spring wave washer, it is by the axial compressive force of the multilayer spring wave washer that the flange of the grinding wheel cover main body is embedding
Enter into front cover U-lag.In the angle for needing to change wheel guard, then compressed by the pressing grinding wheel cover main body described more
Layer spring wave washer can be rotated, and after the angle for reaching needs, the elastic force of the multilayer spring wave washer is by the sand
The flange of wheel cover main body is embedded under the angle in the corresponding slot of front cover U-lag, to realize positioning.
In above-mentioned technical proposal, it is preferred that the thickness of the width of the inner card cage and the wheel guard axle journal matches.
In above-mentioned technical proposal, it is preferred that the notch of the U-lag of the flange of the wheel guard axle journal and the front cover pressing plate
Match, in order to the installation of wheel guard；The flange of the wheel guard axle journal and the notch of the front cover U-lag match, with
Convenient for the positioning and fixation of wheel guard.
In above-mentioned technical proposal, it is preferred that the multilayer spring wave washer is embedded in the front cover inner card cage, between institute
It states between wheel guard axle journal and the front cover.
The utility model has the beneficial effects that user need to only press shield and rotate, so that it may by the multilayer bullet
The elastic force of spring wave washer acts on, and is embedded in the flange of the grinding wheel cover main body in the front cover U-lag, carries out determining for shield
Position and fixation can quickly reach the purpose of replacement angle of protective cover, have to save the process that locking wrench is tightened again of unclamping
The raising working efficiency of effect.

Specific embodiment
This is a kind of angle frosted wheel cover of quick rotational positioning of energy, including wheel guard, front cover pressing plate and angle grinder front cover.
As depicted in figs. 1 and 2,1 there is the wheel guard axle journal 11 that connect with the main body 1, institute in the grinding wheel cover main body
It states and is provided with flange 12 on wheel guard axle journal 11.
Front cover pressing plate through-hole 21 and front cover pressing plate U-lag 22 are provided on front cover pressing plate 2 as described in Figure 3.
As shown in Figure 1, Figure 4 and Figure 5, have in front cover threaded hole 32, front cover U-lag 31 and front cover on the angle grinder front cover
Card slot 33.
The wherein corresponding front cover threaded hole 32 of the front cover pressing plate through-hole 21, and the front cover is fastened on using screw
On, the front cover pressing plate 2 plays position-limiting action, can prevent shield from falling off.The wheel guard axle journal 11 is led to by the flange 12
It crosses the front cover pressing plate U-lag 22 to be installed under the front cover pressing plate 2, and is embedded in the front cover inner card cage 33.Before described
