[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1-3 , the utility model discloses a sand belt bracket, which includes a sand belt bracket main body 1. A sand belt adjustment bracket 3 is movably arranged inside the sand belt bracket main body 1. A sand belt driven wheel 7 is movably sleeved on the top of the sand belt adjustment bracket 3. A sand belt adjustment knob 4 is arranged on one side of the sand belt bracket main body 1. A sand belt adjustment screw rod 41 which penetrates through the sand belt bracket main body 1 at one end and is threadedly sleeved inside the sand belt adjustment bracket 3 is arranged on one side of the sand belt adjustment knob 4.
[0021] The nut barrel 31 is threadedly sleeved with the belt adjusting screw 41, and the belt adjusting rotation is driven by turning the belt adjusting knob 4, so that the belt adjusting rotation drives the belt adjusting screw 41 to rotate. The belt adjusting bracket body 1 is provided with a slot matching the bottom of the belt adjusting bracket 3 to limit the belt adjusting knob 4 from rotating. The belt adjusting knob 4 is arranged on one side of the belt adjusting bracket body 1, and a bearing is provided at the rotating position to avoid left and right movement of the belt adjusting knob 4 when the belt adjusting knob 4 is rotated. The bottom of the belt adjusting bracket 3 extends to the interior of the belt bracket body 1 and is restricted in its movement direction by the belt bracket body 1. When the nut barrel 31 is rotated by the belt adjusting screw 41, the belt adjusting bracket 3 is driven to move horizontally to the left or right inside the belt bracket body 1. The movement direction depends on the direction in which the belt adjusting knob 4 is turned by the user. Figure 3 By rotating the sand belt adjustment knob 4 clockwise or counterclockwise, the sand belt adjustment screw 41 can drive the sand belt adjustment bracket 3 and the sand belt driven wheel 7 to move horizontally to the left or right.
[0022] Specifically, the abrasive belt adjustment and rotation device is arranged on one side of the abrasive belt support body 1 .
[0023] Specifically, a wheel groove 6 movably connected to the sanding belt driven wheel 7 is provided on the top of the sanding belt support body 1, and the wheel groove 6 is used to install the sanding belt driven wheel 7.
[0024] Specifically, a bearing washer 71 and bearing bodies 72 located on both sides of the bearing washer 71 are provided inside the sanding belt driven wheel 7. The bearing washer 71 is used to separate the two bearing bodies 72. The setting of the two bearing bodies 72 ensures the rotation flexibility of the sanding belt driven wheel 7.
[0025] Specifically, the wheel groove 6, the sanding belt driven wheel 7, the bearing washer 71 and the bearing body 72 are collectively sleeved with a driven wheel shaft 8. One end of the driven wheel shaft 8 passes through the wheel groove 6 and the sanding belt driven wheel 7 in sequence from one side of the sanding belt adjustment bracket 3 and is then threadedly sleeved on one side of the sanding belt adjustment bracket 3 or locked by a nut.
[0026] Specifically, a handle 2 is provided at the bottom of the sanding belt holder body 1, and the handle 2 can be held and used after the handle sleeve is installed.
[0027] Specifically, an adjusting spring 5 is provided on one side of the bottom of the sand belt adjustment bracket 3. One end of the adjusting spring 5 away from the sand belt adjustment bracket 3 is embedded in one side of the inner wall of the sand belt bracket body 1. The adjusting spring 5 continuously applies a rebound resistance force to the sand belt adjustment bracket 3, thereby ensuring the flexibility of the sand belt adjustment bracket 3 when moving.
[0028] In summary, for the abrasive belt bracket, by rotating the abrasive belt adjustment knob 4 clockwise or counterclockwise, the abrasive belt adjustment screw 41 can drive the abrasive belt adjustment bracket 3 and the abrasive belt driven wheel 7 to move horizontally left or right. The bottom of the abrasive belt adjustment bracket 3 extends into the interior of the abrasive belt bracket body 1, and its movement direction is restricted by the abrasive belt bracket body 1, so that the abrasive belt adjustment bracket 3 can only translate left and right inside the abrasive belt bracket body 1. The structural design is concise and ingenious, meeting economic benefits and having broad application prospects.
[0029] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
