Detailed Description

Referring to fig. 1-11, a quick release shroud for an angle grinder includes: the machine body 1 is an angle grinder body; the output shaft 2 partially extends out of the machine body 1, and specifically, the output shaft 2 is installed in a head shell of the machine body 1 and is matched with a transmission mechanism in the angle grinder, so that the output shaft 2 can rotate relative to the machine body 1 by taking a first axis 3 as an axis;

further, still include: a first shield 4 is arranged on the machine body 1 around the output shaft 2, in particular on a shaft sleeve outside the output shaft 2;

and a second shield 5 surrounding at least a part of the first shield 4 and detachably connected with the first shield 4, wherein two ends of the second shield 5 are provided with integrally formed latches 6, and the second shield 5 can enter from a radial direction of the first shield 4 (i.e. a first direction 7 shown in fig. 7) and is latched on the first shield 4 through the latches 6.

In addition, as another preferable installation operation mode, the clip 6 at one end of the second shield 5 is firstly engaged with one end of the first shield 4, and then the other end of the second shield 5 is pushed to be clipped onto the first shield 4, and after reaching a certain position, the clips 6 at both ends can be completely buckled. This way is more labour-saving.

In order to function as a guide fit, the second shield 5 is more conveniently mounted. The side of the first shield 4 is provided with a guide part 8 deflected toward the center thereof, and the side of the second shield 5 is provided with a guide groove 9 engaged with the guide part 8.

In order to reinforce the second shield 5 after installation, a step 10 is formed on the inner side of the side portion of the second shield 5, and the step 10 is disposed at the lower edge of the guide groove 9. The step 10 can play a role in guiding and limiting, so that the second shield 5 can be more firmly fixed after being installed, and loose fit caused by vibration in work can be prevented.

Further, a notch 11 and a notch 12 are respectively arranged at two ends of the second shield 5, and the area between the notch 11 and the notch 12 forms the clamping piece 6. The notch 12 has the beneficial effects of light weight and cost saving, and meanwhile, the mold opening in production is more convenient.

The clamping piece 6 is in a hook shape, and a convex part 13 is arranged at the end of the clamping piece 6 far away from the second shield 5. The projection 13 can provide a stopper effect on the end of the first shield 4, and further prevent the second shield 5 from slipping out during operation.

In order to further strengthen the structure of the second shield 5, a plurality of ribs 14 extending from the upper end to the lower end are provided on the outer side of the second shield 5.

Furthermore, the second shield 5 is further provided with an elastic protruding strip 15 protruding towards the central area thereof, and after the first shield 4 and the second shield 5 are installed and matched, the elastic protruding strip 15 can be abutted against the outer side wall of the first shield 4, so that the second shield 5 can be prevented from loosening.

An opening 16 is further provided at the middle end of the side portion of the second cover 5, and an elastic protrusion 15 is formed in the opening 16. The opening 16 is also provided to facilitate the release of air pressure between the first shield 4 and the second shield 5, so as to avoid the generation of negative pressure between the interlayers, which would result in the second shield 5 being difficult to remove from the first shield 4.

When the device is installed, the device has the two modes mentioned above. When the second shield 5 is detached, the clamping piece 6 at one end of the second shield 5 is only required to be slightly pulled to release the limit, and then the second shield 5 is removed. The whole process is very convenient and fast, and the whole stability after installation is strong.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention in any form, and the present invention is not departed from the technical solution of the present invention, and the made simple modification, equivalent change or modification all fall into the protection scope of the present invention.
