Description

Technical Field

[0001] The utility model relates to the technical field of angle grinder handles, and particularly relates to an angle grinder handle guard with a protection function. Background Art

[0002] An angle grinder, commonly known as a cutting machine, is used for cutting and grinding metal materials, plastic materials, ceramics, stone plates, etc. Since the rotation speed of the angle grinder is relatively high, a handle guard that can be held by the user needs to be added to its outer shell to improve the stability when the user holds it. And because the operation of the angle grinder is simple, but the risk is relatively high, often users cause safety accidents due to the angle grinder slipping out of their hands during use due to non-standard operations. Therefore, an angle grinder handle guard with a protection function is needed.

[0003] Currently, the handle guards on common angle grinders are mostly in the shape of a cylinder-like structure and are connected and fixed to the angle grinder through threaded connections. Usually, single or multiple threaded holes are provided on the angle grinder to facilitate the installation of the handle guard. When using this type of angle grinder, depending on the cutting position and cutting posture, sometimes the position of the handle guard needs to be adjusted. Each time, it is necessary to disassemble, move, and reinstall, and the operation steps are complex. Secondly, when using the angle grinder, sometimes due to operation errors or other reasons, the grinding disc breaks away and moves. At this time, the high-speed rotating grinding disc will fly close to the human body and cause cuts, and in severe cases, it will pose a life threat to the user. Summary of the Utility Model

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model provides Figure 1-Figure 3 The angle grinder handle guard with a protective function shown in the figure comprises: a connecting frame 1, which is fixedly connected to the outside of the angle grinder; a supporting frame, which comprises two connecting brackets 2 fixedly connected to one side of the connecting frame 1, one end of the two connecting brackets 2 is fixedly connected to the same concave frame 3, and short rods 4 are fixedly connected to the upper and lower sides of the outer side of the concave frame 3; a guard plate 5, which is fixedly connected to the top and bottom of the connecting frame 1, and one side of the guard plate 5 is fixedly connected to one end of the adjacent short rod 4; a protective component, which comprises a friction sleeve 6 arranged on the supporting frame, and the outer ends of the friction sleeve 6 are fixedly connected to a concave ring 7, and the concave ring 7 is filled with a sponge sleeve 8, the connecting bracket 2 is used to improve the overall stability of the supporting frame, the concave frame 3 is used to reduce the distance between the holding position and the angle grinder, and the short rod 4 is used to support the guard plate 5 to improve the protection The stability of the plate 5 after installation, the guard plate 5 is used to resist the angle grinding disc that may pop out, and improve the protection effect on the user's holding hand. The embossed ring 7 is used to increase the positive pressure on both sides of the holding hand through the sponge sleeve 8, so as to passively increase the damping when holding, and avoid the possibility of the angle grinder accidentally slipping out of the hand. The sponge sleeve 8 can adapt to the user's hand to deform and provide damping. The sponge sleeve 8 should be made of flame retardant and fireproof sponge material. When the user uses the angle grinder, first select one of the friction sleeves 6 for holding according to the actual processing direction. When holding, the hand squeezes the sponge sleeve 8 to both sides, and then limits the hand through the restoring force provided by the embossed ring 7, so as to improve the passive clamping effect. When the angle grinder is opened for processing, the guard plate 5 will block and protect the upper and lower sides of the user's hand to reduce the risk of hand injury. By setting up structures such as the connecting frame 1, the support frame, the guard plate 5 and the protective components, firstly, the friction and squeezing force when the user holds the angle grinder can be improved, thereby minimizing the risk of the angle grinder falling out of the hand. Secondly, the added guard plate 5 can prevent the angle grinding disc from cutting the hand holding the handle when it is detached, thereby protecting the hand safety when holding the angle grinder. Finally, by setting up protective components at multiple locations on the support frame, the user can hold the angle grinder in a variety of postures, and at the same time improve the safety of different holding postures, thereby maximizing the convenience of using the angle grinder and improving the safety.

[0025] Furthermore, a concave portion 9 that bends to one side is provided on the concave-shaped frame 3. A side bracket 10 in a U-shape is also provided on the concave-shaped frame 3. The side bracket 10 is used to connect the support brackets into one body, facilitating production and processing.

[0026] Furthermore, a total of five groups of protection components are provided, which are respectively distributed on the outer side of the concave portion 9 and the outer sides of the two mutually perpendicular ends of the side bracket 10, providing multiple holding positions and facilitating the user to use the angle grinder.

[0027] Furthermore, the shape of the pressing concave ring 7 is bowl-shaped. The outer diameter of one side where two adjacent pressing concave rings 7 are close to each other is larger than that of the side away from each other. The bowl shape can facilitate the pressing concave ring 7 to squeeze the sponge sleeve 8, and at the same time can limit the sponge sleeve 8 and the holding hand, improving the holding stability of the user.

[0028] Furthermore, a rubber layer is sleeved outside the friction sleeve 6. Anti-slip patterns are circumferentially distributed on the rubber layer. The anti-slip patterns and the rubber layer can further increase the resistance and improve the stability when the user holds it, so as to avoid the angle grinder from slipping out of the hand and improve the use safety.

[0029] Furthermore, one end face of the guard plate 5 is perpendicular to the adjacent side on the connection frame 1. The front view section of the guard plate 5 is an arc surface. The guard plate 5 with an arc surface can protect the side close to the abrasive disc to avoid the abrasive disc from breaking away and hurting the arm, providing a certain protection for the user's hand.

[0030] Furthermore, the inner surface of the connection frame 1 fits the outer contour of the angle grinder. The adjacent ends of the connection frame 1 and the connection bracket 2 are welded. The welding process can facilitate the connection and fixation of the connection frame 1 and the connection bracket 2, facilitating assembly.

[0031] Only some exemplary embodiments of the present invention are described above by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
