Description

Technical Field

[0001] The utility model relates to the technical field of angle grinders, in particular to an angle grinder which is easy to adjust. Background Art

[0002] Angle grinder, also known as grinding machine or disc grinder, is a kind of grinding tool used for cutting and grinding fiberglass. Angle grinder is a portable electric tool that uses fiberglass to cut and grind, mainly used for cutting, grinding and brushing metal and stone.

[0003] The existing angle grinder is composed of a power motor, a transmission shaft, a switch, a radiator, a protective housing and a mounting plate. The working principle is that after the staff connects the power supply, the switch is turned on, and the power motor provides power, and the transmission shaft drives the grinding disc on the output shaft to rotate. During the working process, the heat dissipation fan provides heat dissipation for the power motor. The grinding disc on the mounting plate is often connected by bolts, so as to facilitate the replacement of the grinding disc. However, when the existing angle grinder is in use, the angle of the output part of the head is a fixed structure, and the angle cannot be adjusted during use.

[0004] For example, Chinese patent CN215547620U discloses an angle grinder that is easy to adjust. The second switch is set to control the action of the auxiliary motor to drive the rotation of the swing frame, so as to adjust the direction of the output rod shaft. When the direction of the output rod shaft is changed, there is no need to shut down the power motor. That is, the angular position of the output rod shaft is adjusted during the continuous operation of the power motor, thereby solving the problem of the single working mode of the traditional angle grinder device.

[0005] However, during the process of grinding metal and stone, the device is unable to absorb the dust generated by grinding, resulting in the dust being inhaled by the workers, causing damage to their bodies.

[0006] For this reason, we urgently need to provide an angle grinder that is easy to adjust. Utility Model Content

[0007] The purpose of the utility model is to provide an angle grinder that is easy to adjust, so as to solve the problem raised in the above-mentioned background technology that during the process of grinding metal and stone, the dust generated by grinding cannot be absorbed, resulting in the dust being inhaled by the workers and causing damage to their bodies.

[0009] The grinding device includes a dust removal unit, an adjustment unit and a protection unit. The dust removal unit, the adjustment unit and the protection unit are arranged on the left side of the angle grinder, the adjustment unit is arranged on the left side of the angle grinder support platform, and the protection unit is arranged on the outside of the sanding disc.

[0010] The dust removal unit includes a collecting box, an exhaust fan, a fixing frame, a connecting pipe and an air suction port. The collecting box is installed on the left side of the top of the angle grinder, the exhaust fan is fixedly installed on the right side of the collecting box, the fixing frame is fixedly installed on the front and rear ends of the left side of the angle grinder, the connecting pipe is connected to the front and rear ends of the collecting box, and the air suction port is connected to the end of the connecting pipe away from the collecting box.

[0011] Preferably, the adjustment unit includes bracket one, bracket two and a telescopic member, bracket one is fixedly installed at the lower end of the left side of the support platform, bracket two is fixedly installed at the right side of the bottom of the angle grinder, and one end of the telescopic member is rotatably connected to the inside of bracket one.

[0012] Preferably, the protection unit includes a half protective cover, a half bolt and a nut, the half protective cover is installed on the left and right sides of the sanding disc, the half bolt is fixedly installed on the front and rear ends of the half protective cover, and the nut is installed on the outside of the half bolt.

[0013] Preferably, a mounting hole is provided inside the fixing frame, and the connecting pipe passes through the mounting hole, so that the fixing frame plays a role of fixing and supporting the connecting pipe.

[0014] Preferably, the end of the telescopic member away from the first bracket is rotatably connected to the lower end inside the second bracket. When the angle of the sanding disc needs to be adjusted, the telescopic member is started, and while the telescopic member is extended and rotated around the first bracket and the second bracket, the angle grinder is pushed to rotate around the support platform to adjust the grinding angle of the sanding disc.

[0015] Preferably, the half bolts on the adjacent sides of the left and right half protective covers can be threadedly connected with the nuts when they are in contact. After the sanding disc is used, the two half protective covers are installed on the left and right sides of the half protective covers and fixed with nuts to prevent workers from accidentally touching them and causing scratches on the side of the sanding disc.

[0016] Preferably, the connecting pipe and the air suction port are symmetrically distributed at the front and rear ends of the left side of the angle grinder, and the dust generated during grinding is absorbed through the two air suction ports to improve the dust treatment effect.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The angle grinder which is easy to adjust is provided with a dust removal unit and starts the exhaust fan, so that the dust generated during grinding is sucked into a collection box through the suction port via a connecting pipe for collection, thereby preventing the staff from inhaling too much dust and causing damage to their bodies. This solves the problem raised in the background technology that during the grinding of metal and stone, the dust generated by grinding cannot be absorbed, resulting in the dust being inhaled by the staff and causing damage to their bodies.
