Description

Technical Field

[0001] This utility model relates to the field of power tool components, and in particular to a high-efficiency and convenient triangular sander base plate. Background Technology

[0002] Conventional sanding power tools are used for sanding, which is grinding. They are used to grind uneven, thick, or non-compliant materials and objects to make them smoother, flatter, and more uniform in thickness.

[0003] Sanding tools consist of a housing, a movable sanding plate at the bottom of the housing, and a vibrating motor inside the housing. Currently, the sanding plate of sanding tools is usually a single, uniform piece. During long-term use, the bottom surface of the sanding plate gradually wears down and becomes smooth, resulting in a decrease in the sanding effect. Therefore, the sanding plate needs to be replaced regularly. However, replacing a single sanding plate is cumbersome and inconvenient due to its heavy weight and complex fixing method, which is not conducive to the efficient and convenient use of the sanding plate. Therefore, improvements are still needed. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an efficient and convenient triangular sanding base plate, comprising a sanding base plate and a sanding plate. The sanding plate is slidably installed on the sanding base plate. An insert is provided at the middle position of the upper surface of the sanding plate. Two slots are spaced apart at the rear side of the sanding plate. A slot is provided on the lower surface of the sanding base plate. A stepped edge is provided at the rear side of the sanding base plate. Two locking devices are arranged side by side at intervals on the stepped edge. Each locking device includes a left locking foot and a right locking foot. The ends of the left and right locking feet are connected to vertically arranged pressure blocks. A spring is provided between the left and right locking feet. A guide rod passes through the spring. The two ends of the guide rod pass through the left and right locking feet respectively. The guide rod is fixed inside the stepped edge.

[0005] Preferably, two through slots are provided on the side of the step, and the pressure block is installed in the through slots.

[0006] Preferably, the front ends of the left and right locking feet are provided with hooks that can be locked in the locking slots.

[0007] Preferably, the insert and slot are configured in a T-shape.

[0008] The beneficial effects of this utility model are: the structure of this utility model is reasonable and easy to use. After the sanding board is severely worn, a new sanding board can be easily and quickly replaced by sliding and snapping, which improves the ease of use of the triangular sanding base plate.

[0016] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0017] Unless otherwise stated, any feature in this specification may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is merely one example of a series of equivalent or similar features.

[0018] like Figure 1 , 2 A high-efficiency and convenient triangular sanding base plate, as shown in Figures 3, 4, and 5, includes a sanding base plate 1 and a sanding plate 4. The sanding plate 4 is slidably installed on the sanding base plate 1. An insert 5 is provided at the middle position of the upper surface of the sanding plate 4. Two slots 6 are provided at intervals on the rear side of the sanding plate 4. A slot 3 is provided on the lower surface of the sanding base plate 1. A stepped edge 2 is provided on the rear side of the sanding base plate 1. Two locking devices are arranged side by side at intervals on the stepped edge 2. The locking device includes a left locking foot 7 and a right locking foot 8. The ends of the left locking foot 7 and the right locking foot 8 are connected to vertically arranged pressure blocks 12. A spring 10 is provided between the left locking foot 7 and the right locking foot 8. A guide rod 9 passes through the spring 10. The two ends of the guide rod 9 pass through the left locking foot 7 and the right locking foot 8 respectively. The guide rod 9 is fixed inside the stepped edge 2.

[0019] Two through slots 11 are provided on the stepped edge 2, and the pressure block 12 is installed in the through slot 11.

[0020] The front ends of the left locking foot 7 and the right locking foot 8 are provided with hooks that can be locked in the locking slot 6.

[0021] The insert 5 and slot 3 are configured in a T-shape.

[0022] During use, the insert 5 of the sanding plate 4 is aligned with the slot 3 on the sanding substrate 1 and inserted, so that the sanding plate 4 is gradually pushed into the sanding substrate 1. When the rear side of the sanding plate 4 is close to the rear side of the sanding substrate 1, the left locking foot 7 and the right locking foot 8 are pressed inward by pressing the pressure block 12, so that the left locking foot 7 and the right locking foot 8 are engaged in the slot 6 until the rear side of the sanding plate 4 contacts the stepped edge 2 of the sanding substrate 1. At this time, the pressure block 12 is released, so that the left locking foot 7 and the right locking foot 8 are reset under the action of the spring 10 and fixed by the hook, thus completing the installation and engagement of the sanding plate 4 and the sanding substrate 1.

[0023] The guide rod 9 is designed to facilitate more stable left and right movement of the left locking foot 7 and the right locking foot 8.

[0024] The beneficial effects of this utility model are: the structure of this utility model is reasonable and easy to use. After the sanding board is severely worn, a new sanding board can be easily and quickly replaced by sliding and snapping, which improves the ease of use of the triangular sanding base plate.

[0025] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
