A polishing assembly

Abstract

A sanding assembly includes a sanding disc, a handle assembly, a limiting assembly, and a connecting assembly. The handle assembly is mounted on the sanding disc via the limiting assembly. The handle assembly comprises a fixed part, a rotating part, and a switch assembly. The rotating part is rotatably mounted between two fixed parts, one of which has a switch assembly that limits the rotation of the rotating part. A connecting assembly for connecting to an external extension rod is rotatably mounted on the rotating part. The limiting assembly allows the handle assembly to be detachably mounted on the sanding disc, facilitating replacement when the handle assembly or sanding disc is damaged. The connecting assembly allows for an external grip, enabling sanding at heights. The rotating part and rotating block allow for adjustment of the sanding angle from two directions, ensuring the sanding disc remains in contact with the wall when sanding at heights, thus improving sanding efficiency. The switch assembly prevents the rotation of the connecting assembly from interfering with sanding at nearby locations. This design is portable and easy to operate.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] Please see Figures 1 to 5 This utility model provides a technical solution:

[0023] A polishing assembly includes a polishing disc 1, a handle assembly 2, a limiting assembly 3, and a connecting assembly 4. The handle assembly 2 is detachably mounted on the polishing disc 1 via the limiting assembly 3, wherein:

[0024] The handle assembly 2 includes a fixed part 21, a rotating part 22 and a switch assembly. The rotating part 22 is rotatably mounted between two fixed parts 21, and one of the fixed parts 21 is provided with a switch assembly that restricts the rotation of the rotating part 22.

[0025] A connecting component 4, which can be connected to an external extension rod, is rotatably mounted on the rotating part 22. The external extension rod allows the grinding disc 1 to adapt to different grinding scenarios.

[0026] In a preferred embodiment, the limiting component 3 includes a limiting groove 31, a limiting slider 32, a spring 33, and a limiting key 34. The limiting groove 31 is provided on one side of the circular mounting surface of the grinding disc 1, and the limiting slider 32 is movably disposed on the other side. The limiting slider 32 forms a sliding pair on the circular mounting surface of the grinding disc 1. A spring 33 is provided between the limiting slider 32 and the grinding disc 1. A limiting key 34 is provided on the fixing part 21. One of the limiting keys 34 on the two fixing parts 21 engages with the limiting groove 31, and the other engages with the limiting slider 32. The limiting slider 32 can press down on the limiting key 34 on the fixing part 21, thereby achieving the purpose of fixing the handle component 2.

[0027] In a preferred embodiment, the switch assembly includes a pin 23 and a check 24. The pin 23 is movably mounted on the fixed part 21, with the limiting part of the pin 23 facing the limiting groove of the rotating part 22. The pin 23 also has a toggle part for easy manipulation by the user, located outside the fixed part 21. When the pin 23 is inside the limiting groove of the rotating part 22, it restricts the rotation of the rotating part 22. When the pin 23 is pulled out of the limiting groove of the rotating part 22, the rotating part 22 can rotate. The fixed part 21 is also provided with a check 24 to restrict the movement of the pin 23. The check 24 is trapezoidal, and the sliding end of the pin 23 is also provided with a trapezoidal part. When the trapezoidal part of the pin 23 moves to the check 24, it will make frictional contact with it. Therefore, only by forcefully manipulating the pin 23 can the pin 23 lock or unlock the rotating part 22, avoiding accidental operation.

[0028] In a preferred embodiment, the connecting assembly 4 includes a rotating block 41, an external connection part 42, and a blocking part. The rotating block 41 is rotatably mounted in a mounting groove on the rotating part 22, and one end of the rotating block 41 is provided with the external connection part 42. When an external extension rod is needed for grinding, simply rotate the rotating block 41 counterclockwise to connect it to the external extension rod through the external connection part 42. At this time, under the combined action of the convex blocking part 43 and the external extension rod, the rotating block 41 will not rotate excessively, thus not affecting the grinding work. Then, release the pin 23 from restricting the rotation of the rotating part 22, so that the grinding disc 1 can be adjusted from another direction to adjust the grinding direction of the grinding disc 1, thereby ensuring that the grinding disc 1 can always be in contact with the wall.

[0029] In a preferred embodiment, the external part 42 can be a threaded hole or other quick-connect structure.

[0030] The working principle of this utility model:

[0031] When close-range polishing is required, simply pull the limit slider 32 to fix the handle assembly 2 onto the polishing disc 1 via the limit key 34, and then polishing can be performed through the polishing disc 1.

[0032] When grinding is required at a height, rotate the rotating block 41 counterclockwise, then connect it to the external extension rod through the external part 42, and then release the restriction of the pin 23 on the rotation of the rotating part 22. This allows the grinding disc 1 to be adjusted from another direction to perform the grinding work, and then the grinding disc 1 can be driven by the external extension rod to perform the grinding work.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
