Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment: Refer to Figures 1-4 A wall marking device for interior decoration shown in the figure, which includes a base 1. An adjusting block 3 is arranged above the base 1. A lifting mechanism for raising and lowering the adjusting block 3 is installed on the top of the base 1. A rotating hole is opened on the side of the adjusting block 3, and a rotating rod 4 is rotatably installed in the rotating hole. One end of the rotating rod 4 is provided with a rotating handle. A rotating groove is opened on the side of the adjusting block 3, and the other end of the rotating rod 4 extends into the rotating groove and is provided with a rotating plate 5. A threaded hole is opened on the top of the adjusting block 3, and a first bolt is threadedly installed in the threaded hole. The end of the first bolt abuts against the rotating plate 5. A support column 6 is installed on the side of the rotating plate 5, and the other end of the support column 6 is installed with an adjusting frame 7. A scale mark is fixedly arranged on the side of the adjusting frame 7. A lead screw 8 is rotatably installed on the opposite inner walls of the adjusting frame 7. One end of the lead screw 8 extends outside the adjusting frame 7 and is provided with a knob 9. A threaded block 11 is threadedly sleeved on the lead screw 8. A fixing column is installed on the top of the threaded block 11, and a pen sleeve 12 is installed on the top of the fixing column. A paintbrush is detachably installed on the pen sleeve 12 through a second bolt. A moving groove is opened on the top of the adjusting frame 7, and a moving block 14 is slidably installed in the moving groove. A limiting plate 15 is installed on the side of the moving block 14, and a fixing mechanism is arranged on the moving block 14.

[0023] With the above structure, during use, first move the base 1 to the designated position, then fix the paintbrush on the pen sleeve 12 through the second bolt, then adjust the height through the lifting mechanism, and then adjust the adjusting frame 7 to an appropriate angle through the rotating rod 4, the rotating plate 5, the rotating handle, the first bolt, and the support column 6. When a line of a certain length needs to be drawn, first release the fixation of the moving block 14 through the fixing mechanism. At this time, move the moving block 14 to the designated position through the scale markings. When the movement is complete, fix the moving block 14 at any position through the fixing mechanism, and then rotate the knob 9. The rotation of the knob 9 drives the rotation of the lead screw 8. The rotation of the lead screw 8 causes the threaded block 11 to move horizontally. The movement of the threaded block 11 drives the pen sleeve 12 to move through the fixing column. When the threaded block 11 contacts the limiting plate 15, due to the blocking of the limiting plate 15, the threaded block 11 cannot move, and further the knob 9 cannot rotate. Thus, the drawable line length can be directly adjusted as needed, which is convenient for use.

[0024] As Figure 4 shown, the fixing mechanism includes an activity cavity opened in the moving block 14. Two sliding rods are installed on the opposite inner walls of the activity cavity. Two moving plates 16 are slidably installed together on the two sliding rods. Fixing blocks 17 are installed on the side parts of the two moving plates 16. Avoidance holes are opened on the side parts of the moving block 14 that are far away from each other. The two fixing blocks 17 respectively penetrate through the two avoidance holes. Elastic pulling units are arranged on the side parts of the two moving plates 16. Triangular blocks 19 are installed on the tops of the two moving plates 16. A through hole is opened on the top of the moving block 14. A pressing rod 20 is slidably installed in the through hole. A pressing plate is installed on the top of the pressing rod 20. The bottom end of the pressing rod 20 extends into the activity cavity and a U-shaped plate 21 is installed. An elastic reset unit is arranged on the top of the U-shaped plate 21. The advantage of such a setting is that through the settings of the sliding rods, the moving plates 16, the fixing blocks 17, the triangular blocks 19, the pressing rod 20, the pressing plate, and the U-shaped plate 21, it is convenient to fix the moving block 14 at any position.

[0025] As Figure 4 shown, the elastic pulling unit includes two tension springs 18 installed on the side parts of the moving plate 16. The other ends of the two tension springs 18 are installed on the side inner wall of the activity cavity. The advantage of such a setting is that through the setting of the tension spring 18, when the triangular block 19 is not stressed, under the action of the tension spring 18, the moving plate 16 is reset.

[0026] As Figure 4 shown, the elastic reset mechanism includes a reset spring 22 installed on the top of the U-shaped plate 21. The top end of the reset spring 22 is installed on the top inner wall of the activity cavity. The advantage of such a setting is that through the setting of the reset spring 22, when the U-shaped plate 21 is not stressed, under the action of the reset spring 22, the U-shaped plate 21 is reset.

[0027] As Figure 4As shown in the figure, a guide rod 10 is installed on the relative inner wall of the adjustment frame 7, a guide hole is provided on the side of the threaded block 11, the guide rod 10 passes through the guide hole, a limiting rod 13 is installed on the relative inner wall of the moving groove, a limiting hole is provided on the side of the moving block 14, and the limiting rod 13 passes through the limiting hole. The advantage of this setting is that through the setting of the guide rod 10, the threaded block 11 moves along the horizontal direction, and through the setting of the limiting rod 13, the moving block 14 moves along the horizontal direction.

[0028] As Figure 1 shown in the figure, the lifting mechanism includes a telescopic hydraulic cylinder 2 installed on the top of the base 1, and the bottom of the adjustment block 3 is installed on the output end of the telescopic hydraulic cylinder 2. The advantage of this setting is that through the setting of the telescopic hydraulic cylinder 2, it is convenient to adjust the height of the adjustment block 3.

[0029] As Figure 4 shown in the figure, friction pads are installed on the sides of both fixed blocks 17. The advantage of this setting is that through the setting of the friction pads, a certain amount of friction is increased to prevent the fixed blocks 17 from moving.

[0030] The working principle of this utility model:

[0031] When in use, first move the base 1 to the designated position, then fix the paintbrush on the pen sleeve 12 through the second bolt, and then adjust the height through the telescopic hydraulic cylinder 2. Then adjust the adjustment frame 7 to the appropriate angle through the rotating rod 4, the rotating plate 5, the rotating handle, the first bolt and the support column 6. When a line of a certain length needs to be drawn, first press the pressing plate. The movement of the pressing plate drives the movement of the pressing rod 20, and the movement of the pressing rod 20 drives the movement of the U-shaped plate 21. When the bottom of the U-shaped plate 21 contacts the triangular block 19, the continuous movement of the U-shaped plate 21 will squeeze the triangular block 19, causing the two triangular blocks 19 to approach each other. The movement of the triangular block 19 will cause the movable plate 16 to move. The movement of the movable plate 16 causes the fixed block 17 to move under the action of the sliding rod, thereby releasing the fixation of the moving block 14. At this time, move the moving block 14 to the designated position through the limiting rod 13 and the scale mark. When the movement is completed, release the pressing plate. At this time, the U-shaped plate 21 is not stressed, and under the action of the return spring 22, the U-shaped plate 21 is reset. At the same time, the U-shaped plate 21 no longer squeezes the triangular block 19, and the triangular block 19 is not stressed. Under the action of the tension spring 18, the movable plate 16 is reset. The reset of the movable plate 16 drives the reset of the fixed block 17, thereby fixing the moving block 14 at any position. Then rotate the knob 9. The rotation of the knob 9 drives the rotation of the lead screw 8. The rotation of the lead screw 8 causes the threaded block 11 to move horizontally under the action of the guide rod 10. The movement of the threaded block 11 drives the pen sleeve 12 to move through the fixed column. When the threaded block 11 contacts the limiting plate 15, due to the blockage of the limiting plate 15, the threaded block 11 cannot move, thereby making the knob 9 unable to rotate. Thus, the drawable line length can be directly adjusted as needed, which is convenient for use.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
