Description

Technical Field

[0001] The present application relates to a wall grinding machine, in particular to a long-handled wall grinding machine. Background Art

[0002] Wall grinders are used for grinding and polishing walls. Therefore, the operator needs to lift the wall grinder to use, that is, the wall grinder is in a vertical state most of the time when in use. Generally, the wall grinder includes a housing, a motor arranged in the housing, and a grinding disc driven by the motor. The grinding disc and the housing form a dust suction channel. A handle is connected to the outside of the housing. The handle is provided with a dust collecting pipe connected to the dust suction channel. The dust collecting pipe is connected to the dust collecting bag through a hose to collect the dust after grinding. However, since the top of the wall is high, an extended handle rod is required to extend the wall grinder to the top of the wall. Therefore, the operator's arm of force is longer when lifting the wall grinder, which makes the operator more laborious when working. It is impossible to hold the machine in the air for a long time. Usually, the tail of the machine is placed on the ground for leverage. In addition, when the operator is resting, in order to facilitate the placement of the machine and the next time the machine is lifted for operation, the grinding head of the machine is generally placed against the wall, and the tail of the machine is placed on the ground. However, this will cause the hose of the wall grinder to support the ground, which will cause great wear on the hose and cause the hose to be easily damaged. Therefore, it is necessary to improve this to protect the hose and increase the service life of the hose. Utility Model Content

[0021] This embodiment provides a wall grinding machine 100, such as Figure 1 The wall grinding machine 100 comprises a housing 1, a grinding disc 2 rotatably mounted on the housing 1, a motor driving the grinding disc 2 to rotate, the housing 1 externally connected to the dust collecting pipe 3, and an exposed hose 5 connected to the dust collecting pipe 3, the hose 5 being attached with a dust collecting bag. The grinding disc 2 and the housing 1 form a dust suction channel, and the dust absorbed by grinding enters the dust collecting pipe 3 through the dust suction channel, and is then collected into the dust collecting bag through the hose 5.

[0022] like Figure 3As shown, the wall grinding machine 100 further includes a hose bracket 4, and the hose bracket 4 includes a head 41, a protective portion 42, and a base 43. The head 41 is configured to be connected to the dust collecting pipe 3. The protective portion 42 has a space for accommodating a hose 5, and the space passes through the extension direction of the hose 5. The protective portion 42 at least partially surrounds the hose 5 and supports the hose 5. The base 43 has a supporting surface in contact with the ground, so that the hose bracket 4 can be supported on the ground.

[0023] After the wall grinder 100 is provided with a hose holder 4 on the dust collecting pipe 3, the hose 5 is protected. More importantly, when the wall grinder 100 is placed upright, or when the grinding disc 2 of the wall grinder 100 is placed tilted against the wall, the hose holder 4 is supported on the ground. Therefore, the weight of the entire wall grinder 100 is applied to the hose holder 4 instead of the exposed hose 5. Therefore, the hose 5 is prevented from being directly pressed against the ground and damaged, thereby improving the service life of the hose 5.

[0024] Specifically, in this embodiment, the head 41 , the protection portion 42 and the base 43 of the hose bracket 4 are integrally formed and may be made of plastic or metal material to ensure its strength.

[0025] Combination Figure 3 As shown, the head 41 of the hose bracket 4 includes a sleeve 411 in a circular ring shape, and the hose 5 passes through the sleeve 411 .

[0026] The head 41 also includes two claws 412 connected to the outside of the sleeve 411, and the claws 412 are detachably connected to the dust collecting pipe 3. The two claws 412 are symmetrically arranged on both sides of the head 41. The claws 412 include a pressing portion 412a and a buckle portion 412b. The pressing portion 412a extends along the extension direction of the protective portion 42, and the pressing portion 412a is close to the end of the sleeve 411 to form the buckle portion 412b, and the buckle portion 412b extends inwardly along the radial direction. The dust collecting pipe 3 has a through hole, and the buckle portion 412b is snapped into the through hole of the dust collecting pipe 3, so that the hose bracket 4 is connected to the dust collecting pipe 3. Pressing the pressing portion 412a can cause the buckle portion 412b to be slightly deformed, so that the buckle portion 412b is separated from the through hole of the dust collecting pipe 3, and the hose bracket 4 can be removed from the dust collecting pipe 3.

[0027] Preferably, the buckle portion 412b exceeds the end of the sleeve 411, and the dust collecting tube 3 is inserted between the sleeve 411 and the pressing portion 412a. The buckle portion 412b will not interfere with the sleeve 411, and part of the pressing portion 412a can also be sleeved on the outer periphery of the dust collecting tube 3, so that the connection between the hose bracket 4 and the dust collecting tube 3 is tighter.

[0028] The protection part 42 of the hose bracket 4 includes an inwardly concave arc wall, the arc wall partially surrounds the outer circumference of the hose, and the arc wall is connected with the sleeve 411 to form a space for accommodating the hose 5, which is used to protect the hose 5. Figure 2 As shown, when the wall grinder 100 is placed upright, or when the grinding disc 2 of the wall grinder 100 is placed tilted against the wall, the hose 5 from the ground to the dust collecting pipe 3 is curved, and the protective portion 42 fits the bent shape of this part of the hose to form an arc-shaped wall, thereby protecting this part of the hose 5. It can be understood that a shell is added to this part of the hose 5 to further protect the hose 5.

[0029] The protection part 42 is provided with a reinforcing rib 422 on the back of the arc-shaped wall, and a support leg 423 is formed at the bottom of the reinforcing rib 422, and the support leg 423 extends to the base 43 to support the hose bracket 4 to stand upright on the ground. The support leg 423 of the reinforcing rib 422 is triangular, so that the base 43 is supported on the ground more stably.

[0030] The above is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Although the present application has been disclosed as a preferred embodiment as above, it is not intended to limit the present application. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present application.
