Description

Multipurpose protective cover for angle grinder

Technical Field

The utility model belongs to the technical field of electric tool part and specifically relates to a multi-purpose protection casing of angle mill is related to.

Background

Angle grinders (grinders), also known as grinders or disc grinders, are abrasive tools used for cutting and grinding glass fiber reinforced plastics. An angle grinder is a portable electric tool for cutting and polishing glass fiber reinforced plastics, and is mainly used for cutting, grinding and brushing metal and stone materials. According to different use functions, the angle grinder can be respectively provided with a cutting piece or a polishing piece. The angle grinder has high rotating speed, and certain risks exist when the cutting piece and the grinding piece work, so the angle grinder is generally provided with a protective cover for protection. The cutting blade and the polishing blade have different corresponding protective cover structures due to different operation modes, and the cutting blade needs to be matched with a protective cover with a full-protection structure due to the fact that the outer ring is in contact with a cutting object; when the polishing disc works, the polishing disc is contacted with an object through a polishing surface, and a shield of a semi-protection structure is needed to be matched; when the working state of the polishing plate with a small polishing angle is achieved, in order to achieve a better protection and dust prevention effect, the semi-protection protective cover needs to be expanded, and the top surface of the polishing plate is enabled to be fully covered.

At present, generally all be the guard shield of two kinds of structures of collocation when most angle grinder goes out goods on the market, the usage is different, need dismantle the change, and the operation is carried and is all very inconvenient, if can carry out the dismantlement formula combination with the guard shield of two kinds of structures, then will improve the convenience of operation. In order to solve the problem, a patent with a publication number of CN208261956U in the prior art discloses an angle grinder capable of combining a slicing shield and a grinding disc shield, and the patent document discloses that the slicing shield can be detachably sleeved on the outer side of the grinding disc shield and is limited by clamping pieces at two ends of the slicing shield, in the mode, the clamping pieces are preferably metal pieces and are firmly fixed, but the elasticity is insufficient, the disassembly is troublesome in the actual use process, the manual disassembly is difficult, other tools are often needed, and the fixing plates are arranged at the upper part and the lower part of the slicing shield, so that more materials are used, and the production cost is increased; and its guard shield only has two kinds of states, when working condition to polishing the angle is little, in order to play better protection dustproof effect, can't expand the guard shield of half protection.

In this regard, there is a need for improvement.

Disclosure of Invention

The utility model provides a not enough to prior art, the utility model provides a multi-purpose protection casing of angle mill can effectively solve the problem that above-mentioned traditional angle mill protection casing exists, and overall structure is simple, greatly increased the area of protection, can change the state of protection casing according to the application method difference of angle mill to this forms better matching effect.

The utility model provides a technical scheme that its technical problem adopted is: the multipurpose protective cover of the angle grinder comprises a grinding disc and a grinding disc shell, wherein a protective cover is arranged on the grinding disc shell, a protective sheet is arranged on the protective cover, a connecting piece is arranged on the protective cover and the grinding disc shell, and the protective cover is arranged on the grinding disc shell and can change positions through the connecting piece.

Among the above-mentioned technical scheme, furtherly, the protection casing sets up to left protection casing and right protection casing, the radian of left side protection casing with the radian of right protection casing with the abrasive disc shell radian phase-match just is greater than 90, sets up like this left side protection casing with right protection casing relocation, the abrasive disc shell with left side protection casing with right protection casing produces the coincidence part and plays the supporting role.

In the above technical scheme, further, a sliding groove is formed in the left protective cover and the right protective cover, a sliding block is fixedly arranged on the protective sheet, the sliding block is embedded in the sliding groove and slides, and therefore the protective sheet is arranged, after the left protective cover and the right protective cover change positions, the protective sheet slides through the sliding groove and fills the vacant part.

Among the above-mentioned technical scheme, furtherly, the connecting piece is magnet, magnet sets up protection casing inner wall edge, left side protection casing with right protection casing side is provided with magnet, be provided with on the abrasive disc shell with left side protection casing with right side protection casing is corresponding magnet sets up like this, is favorable to left side protection casing with right side protection casing is dismantled and is laminated on the abrasive disc shell. It should be noted that the utility model discloses a for being used for polishing/cutting such as the special angle mill of non-metallic material such as glass steel, glass, stone material, macromolecular material to this can guarantee to avoid leading to the metal powder adhesion on the protective housing body because of the grinding metal, influences the use.

In the technical scheme, further, the left protective cover and the right protective cover can change the installation position states to be an initial state, a second state and a third state respectively, and thus, a user can change the installation state according to different use methods of the angle grinder in demand.

In the above technical solution, further, the initial state is: the left protective cover is attached to the side face of the right protective cover and adsorbed on the upper surface of the grinding sheet shell; the second state is: the left guard rotates left along the sheet shell and the right guard rotates right along the sheet shell, the left guard rotates at an angle consistent with the right guard and creates a reattached portion with the sheet shell; the third state is: the left protective cover is attached to the side face of the right protective cover and adsorbed on one side of the opposite exposed face of the grinding sheet shell.

The utility model has the advantages that: the guard shield of angle mill comprises fixed protection casing, the left protection casing of detachable, right protection casing, and left protection casing right side protection casing detachably connects on the guard shield, through the relative hookup location of adjusting left protection casing, right protection casing and protection casing, can form the structure of three kinds of different states to this use that can match different scenes.
