Description

Technical Field

[0001] The utility model relates to the technical field of tools for indoor decoration, in particular to a gypsum board chamfering device. Background Art

[0002] When a family is doing interior decoration, gypsum boards are used for decoration. When the gypsum boards are spliced ​​at corners, the sides of the gypsum boards need to be chamfered. The existing method is to use a chamferer, which is installed on the sides of the gypsum boards. By pulling the chamferer, the sides of the gypsum boards will be cut by the blade of the chamferer to complete the chamfering work. After the chamferer has been used for a long time and many times, the blade will become blunt, thereby affecting the cutting. Therefore, it is necessary to displace the blade so that the unused blade position is moved to the feed port. However, in the existing chamferer, the blade is directly fixed to the outer wall of the chamferer by a pressing plate. Therefore, when moving the blade position, the user's hand will directly contact the blade. The outer wall of the blade is smooth and the edges are sharp, so it will cause scratches to the user's hands. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model provides Figure 1-4A gypsum board chamfering tool shown in the figure includes a chamfering tool 1, a chamfering groove 2 for placing a board is opened at the bottom of the chamfering tool 1, a blade 3 for cutting the board is arranged on the top of the chamfering tool 1, a pressing plate 4 for fixing the blade 3 is arranged at one end of the blade 3, and a moving mechanism for moving the blade 3 is arranged at the other end of the blade 3, the moving mechanism includes a moving component and a connecting component, the moving component includes an edge plate 7, and a limiting member for limiting the moving direction of the edge plate 7 is arranged at the bottom end of the edge plate 7.

[0019] Specifically, a mounting groove 5 for mounting a blade 3 is provided at the top of the chamfering tool 1 , a feeding port 6 for feeding a plate is provided at the bottom end of the inner wall of the mounting groove 5 , and the bottom end of the pressing plate 4 is fixedly connected to the inner wall of the mounting groove 5 .

[0020] Furthermore, the pressing plate 4 is fixed to one side of the inner wall of the mounting groove 5 by bolts to press and fix the blade 3. The chamfering groove 2 is V-shaped, the mounting groove 5 is an oblique V-groove, and the feed port 6 is the intersection of the top of the chamfering groove 2 and the bottom of the mounting groove 5. Therefore, when the board is chamfered and cut, the board is placed in the chamfering groove 2, and the chamfering device 1 is pulled to make the corners of the board pass through the feed port 6 and be cut by the blade 3 to complete the chamfering work. The chamfering device 1, the chamfering groove 2, the blade 3, the pressing plate 4, the mounting groove 5 and the feed port 6 constitute the existing gypsum board 45° V-type chamferer.

[0021] Specifically, the transverse cross-section of the edging plate 7 is in the shape of a letter "7", and the edging plate 7 is sleeved on the outer wall of the other end of the blade 3. The connecting component includes a connecting plate 9, one end of the connecting plate 9 is fixedly connected to one end of the edging plate 7, and the bottom end of the connecting plate 9 is fixedly connected with a plug-in column 10. A circular hole is opened on one side of the top end of the blade 3, and the plug-in column 10 is connected through the circular hole.

[0022] Furthermore, the inner wall of the edging plate 7 can fit the two side edges of the corner of the blade 3, the size of the plug-in column 10 corresponds to the size of the circular hole of the blade 3, and the thickness of the plug-in column 10 corresponds to the thickness of the blade 3. Therefore, when the plug-in column 10 is inserted into the circular hole and the edging plate 7 wraps the corner of the blade 3, the blade 3 and the edging plate 7 can be stably installed. Therefore, after the blade 3 is used for a long time and the blade edge becomes blunt, the pressing plate 4 can be released from the pressing of the blade 3, and then the blade 3 can be moved by pushing the edging plate 7 to move the unused blade edge part to the position of the feed port 6, so that when moving, the user's hand will not touch the blade 3, which plays a protective role. The material of the edging plate 7, the connecting plate 9 and the plug-in column 10 is the same as that of the chamfering device 1.

[0023] Specifically, the limiting member includes a limiting block 8, the top of which is fixedly connected to the bottom of the edging plate 7, and a movable groove 11 for sliding and inserting the limiting block 8 is opened on one side of the inner wall of the mounting groove 5, and the vertical cross-sections of the limiting block 8 and the movable groove 11 are both T-shaped.

[0024] Furthermore, the material of the limiting block 8 is the same as that of the edging plate 7, and the size of the vertical section of the limiting block 8 is 0.98 times the size of the vertical section of the moving groove 11. The limiting block 8 is fixed to one side of the bottom end of the edging plate 7 close to the connecting plate 9, and the moving groove 11 is a straight groove. The inclination direction of the moving groove 11 is the same as the inclination direction of the blade 3, so that when the edging plate 7 is pushed, under the restriction of the limiting block 8, it can be ensured that when the edging plate 7 drives the blade 3 to move, the position of the blade will not change. When installing the blade 3, first insert the plug-in column 10 into the circular hole of the blade 3, and the corner of the blade 3 away from the blade is clamped with the edging plate 7, and then the blade 3 is placed on one side of the inner wall of the installation groove 5, and by pushing the edging plate 7, the limiting block 8 is slidably and interlaced with the moving groove 11, and finally the blade 3 is fixed by the pressing plate 4.

[0025] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
