Description

Technical Field

[0001] The utility model belongs to the technical field of building construction tool design, in particular to a multifunctional gypsum board edge grinding tool. Background Art

[0002] The gypsum board edge grinding tool is used to grind the edge of the gypsum board after cutting, so that the edge of the gypsum board is neat and burr-free. Most of the traditional gypsum grinding is sandpaper grinding, which is time-consuming and labor-intensive, has a large loss of sandpaper, and has poor effect. At the same time, a large amount of dust will be generated during use and directly float in the air, which not only poses a threat to the health of workers, but also may pollute the construction environment, and it is inconvenient to operate when performing grinding operations in an environment with insufficient light. At present, there are also some simple handheld grinding tools on the market, such as a gypsum board trimmer disclosed in prior art 1 (CN205591497U). Although it can be used repeatedly, the material waste is small, and it is more labor-saving, it does not have an accompanying lighting device, and there is a defect that it cannot be constructed under insufficient light conditions. In addition, there is no temporary dust storage structure designed, and a large amount of dust will still be generated during the grinding process. It cannot be adjusted to adapt to boards of different thicknesses, and its flexibility is poor. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a multifunctional gypsum board edge grinding tool, which solves the problems of traditional grinding tools such as large dust, inability to operate under insufficient light conditions, and inability to be flexibly adjusted.

[0004] The utility model achieves the above technical objectives through the following technical means.

[0005] A multifunctional gypsum board edge grinding tool comprises an outer frame, a left movable side baffle plate, and a right movable side baffle plate. Grinding teeth are arranged inside the outer frame, and a handle is installed on the upper surface of the outer frame. Sliding groove tracks are arranged at positions near the front and rear ends of the lower surface of the outer frame. The left movable side baffle plate and the right movable side baffle plate are movably installed in the sliding groove tracks by mortise and tenon joints. A lighting strip, a battery compartment, and a light strip switch are also installed on the outer frame.

[0006] Furthermore, the structural dimensions of the left movable side baffle and the right movable side baffle are the same, both are L-shaped structures, and the rear ends are provided with tail plates for achieving closure; elastic pads are installed on the side edges of the rear end of the left movable side baffle and under the left movable side baffle.

[0007] Furthermore, a plurality of arc-shaped depressions are provided on the lower surface of the handle.

[0008] Furthermore, the angle formed between the grinding teeth and the outer frame is 45°.

[0009] The utility model has the following beneficial effects:

[0010] The tool designed by the utility model adds movable baffles and elastic cushions on both sides in the grinding dust falling area, so that it can adapt to gypsum boards of different thicknesses, and during the grinding process, the floating dust generated by grinding can be collected in the baffles and dumped uniformly to prevent dust from flying during construction. At the same time, the step of repeatedly replacing sandpaper in the traditional grinding process can be omitted, thereby improving construction safety and construction efficiency. In addition, the utility model adds a light strip in front of the grinding tool for lighting, which can ensure convenient construction under low light conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0018] like Figures 1 to 5 As shown, the multifunctional gypsum board edge grinding tool of the utility model includes a handle 1, an outer frame 2, a left movable side baffle 6, a right movable side baffle 10, grinding teeth 3, a battery compartment 4, a lighting strip 8, and an elastic cushion 7.

[0019] like Figures 1 to 5As shown, a sliding groove track 9 is provided at the position near the front and rear ends of the lower surface of the outer frame 2; two connecting parts are installed on the top of the left movable side baffle 6, and the two connecting parts are respectively installed in the sliding groove track 9 at the front and rear ends of the outer frame 2 through the mortise and tenon splicing principle, so that the left movable side baffle 6 can move left and right along the outer frame 2; the left movable side baffle 6 and the right movable side baffle 10 have the same structural dimensions, both of which are L-shaped structures, and the rear ends are provided with a tail plate for achieving closure, and the installation method between the right movable side baffle 10 and the sliding groove track 9 is the same as that of the left movable side baffle 6; based on the mortise and tenon principle, the gap between the movable side baffle 6 and the right movable side baffle 10 is adjustable, so as to adapt to plates of different thicknesses.

[0020] like Figure 2 As shown, elastic pads 7 are installed on the rear end side of the left movable side baffle 6 and below the left movable side baffle 6.

[0021] like Figure 1 , 2 As shown, a lighting strip 8 is installed on the lower surface of the outer frame 2 near its front end, and is powered and controlled by a battery compartment 4 and a light strip switch 5; the battery compartment 4 and the light strip switch 5 are both installed on the upper surface of the outer frame 2 near the front end, the battery compartment 4 is used to hold the light strip power supply, and the light strip switch 5 is used to control the opening and closing of the lighting strip 8.

[0022] like Figures 1 to 5 As shown, a handle 1 is installed on the upper surface of the outer frame 2, and a plurality of arc-shaped depressions are provided on the lower surface of the handle 1 so as to better fit the human hand during use. The depth of the arc-shaped depression is 5 mm, and the length of the arc-shaped depression is consistent with the width of the handle 1, both of which are 20 mm; grinding teeth 3 are provided on the outer frame 2, and the angle formed between the grinding teeth 3 and the outer frame 2 is 45°, and each grinding tooth 3 has a width of 10 mm and a length of 100 mm.

[0023] The elastic cushion 7 is made of rubber; the outer frame 2, the handle 1, and the grinding teeth 3 are all made of 304 stainless steel, and the three are fixed together by welding.

[0024] The elastic pad 7 can fill the gap between the left movable side baffle 6, the right movable side baffle 10 and the plate, effectively preventing dust from leaking out. The left movable side baffle 6, the right movable side baffle 10 combined with the elastic pad 7 can form a semi-sealed space with only an outlet at the front with the outer frame 2 and the plate, which is used to receive dust generated during the use of the tool. After a certain amount of dust is accumulated, the dust can be poured out through the front outlet. Based on the lighting strip 8, operations can be achieved in insufficient light environments, making up for the shortcomings of traditional tools that lack light.

[0025] The embodiments are preferred implementations of the present invention, but the present invention is not limited to the above-mentioned implementations. Without departing from the essential content of the present invention, any obvious improvements, substitutions or modifications that can be made by those skilled in the art are within the protection scope of the present invention.
