Description

Technical Field

[0001] The utility model relates to the field of automobile armrest processing, in particular to a protective device for polishing automobile armrests. Background Art

[0002] The central armrest of a car is also called an automobile armrest. It was originally designed to provide elbow support for passengers. Later, it developed into a storage box in the car, including an armrest panel, which is convenient for conversation, office work, and reading documents. After long-term use, its surface will have scratches and leather blisters. When repairing, it is necessary to apply a repair cream to the scratches and blisters on the hand skin. After the repair cream dries, the repaired area is polished flat, and then a second repair is performed. After the repair, the surface is polished smooth. When grinding, a handheld grinder is usually used. When grinding, contact with the surface of the armrest will generate dust, and this dust will spread around under the action of the grinding wheel, and it is easy to be absorbed by the surrounding staff, which will affect the health of nearby people. For this reason, we designed a protective device for polishing automobile armrests. Utility Model Content

[0003] In order to solve the technical problem that dust generated when grinding an armrest will spread to the surroundings, the utility model provides a protective device for grinding an automobile armrest.

[0008] A support seat is arranged above the outer shell cover, and the handle is overlapped on the support seat to support the handle so that it is in a horizontal state, and the grinding wheel will not deflect due to the shift of the center of gravity.

[0009] As a further improvement of the above scheme, the curved semicircular structure of the curved portion forms an arc-shaped placement portion, an annular air pipe is arranged in the arc-shaped placement portion, the annular air pipe is connected to a dust suction pipe through a connecting head, the dust suction pipe is connected to the pipe of an external vacuum cleaner, and the dust generated during grinding inside the outer shell cover can be absorbed and will not spread outward.

[0020] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0021] Example:

[0022] Please combine Figure 1-Figure 4 A protective device for polishing an automobile armrest in this embodiment includes an outer shell cover 1. The lower part of the outer shell cover 1 is integrally bent outward to form a curved portion 11. A polishing motor shell 4 is rotatably installed above the outer shell cover 1. A polishing motor is arranged inside the polishing motor shell 4. The output shaft of the polishing motor is connected to a driving shaft 51. The driving shaft 51 is movably placed inside the outer shell cover 1, and a polishing wheel 5 is fixed to the bottom end of the driving shaft 51. The polishing wheel 5 is located above the bottom end of the curved portion 11. The outer shell cover 1 is made of transparent material, which is convenient for observing the actual polishing condition of the internal grinding wheel 5.

[0023] Mounting shaft plates 15 are symmetrically arranged on the front and rear sides above the outer shell cover 1, and mounting shafts are arranged on the front and rear sides of the grinding motor shell 4. The grinding motor shell 4 is rotatably arranged on the two mounting shaft plates 15 through the mounting shafts. The mounting shaft plates 15 are L-shaped and can be screwed on the top of the outer shell cover 1, so that the grinding motor shell 4 can be rotatably installed between the two mounting shaft plates 15.

[0024] A deflection groove 16 is formed downward through the middle of the upper part of the outer shell cover 1. The deflection groove 16 is a strip-shaped structure, and the drive shaft 51 passes through the deflection groove 16 and is placed inside the outer shell cover 1. When the grinding motor housing 4 is deflected, the drive shaft 51 can be deflected at a certain angle along the deflection groove 16, so that the grinding wheel 5 can grind the handrail workpiece below.

[0025] A handle 41 is provided on the grinding motor housing 4, and a power switch of the grinding motor is placed on the handle 41. By deflecting the handle 41, the grinding wheel 5 can be deflected at a certain angle;

[0026] A support seat 12 is arranged above the outer shell cover 1, and the handle 41 is overlapped on the support seat 12, which can support the handle 41 and keep it in a horizontal state, and the grinding wheel 5 will not deflect due to the shift of the center of gravity.

[0027] The curved portion 11 is bent into a semicircular structure to form an arc-shaped placement portion 14, in which an annular air pipe 2 is arranged, and the annular air pipe 2 is connected to a dust suction pipe 3 through a connector 21, and the dust suction pipe 3 is connected to the pipe of an external vacuum cleaner, so that the dust generated when the inside of the outer shell cover 1 is polished can be absorbed and will not spread outward.

[0028] The outer ring surface of the annular air pipe 2 is provided with a plurality of circumferentially distributed docking ports 22 on the inner side, and the curved portion 11 of the outer shell cover 1 is provided with a plurality of annularly distributed connecting ports 13, which are connected with the docking ports 22. The dust inside the outer shell cover 1 can be absorbed into the annular air pipe 2 through the connecting ports 13 and the docking ports 22, and then can be collected.

[0029] The implementation principle of a protective device for polishing an automobile armrest in the embodiment of the present application is as follows: when polishing, connect the dust suction pipe 3 to the pipe of an external vacuum cleaner, and then fit the outer shell cover 1 to the surface of the armrest. Since a curved portion 11 is provided below the outer shell cover 1, and the curved portion 11 is in a semicircular structure, the curved portion 11 is in line contact with the surface of the armrest, and their overall contact area is small and the surface is smooth, which will not cause secondary scratches to the armrest. Then the user holds the handle 41 and turns on the power of the polishing motor, and then deflects the handle 41 toward the seat. At this time, the left end of the polishing wheel 5 will deflect downward and contact the surface of the armrest, so that the surface of the armrest can be polished. In the process of polishing, the polishing wheel 5 and the outer shell cover 1 can also be pushed, so that the armrest can be polished in all directions. The dust generated during polishing will be collected by the vacuum cleaner through the annular air pipe 2 and the dust suction pipe 3, and will not spread around, thereby ensuring the cleanliness of the surrounding environment.

[0030] By deflecting the grinding wheel 5 and setting it inside the outer shell cover 1, and setting an annular air pipe 2 for absorbing dust on the outer side of the outer shell cover 1, the dust generated during grinding is located inside the outer shell cover 1 and can be absorbed by the annular air pipe 2 without spreading to the surroundings, thereby ensuring the cleanliness of the surrounding environment;

[0031] By providing a curved portion 11 with a semicircular structure at the bottom end of the outer shell cover 1, the curved portion 11 is in linear contact with the surface of the handrail, and their overall contact area is small and the surface is smooth, which will not cause secondary scratches to the handrail.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
