[0025] Example

[0026] See also Figure 1-Figure 5 The utility model provides a wall verticality detection device, including a ruler body 10, a pendulum assembly 20 and an angle measurement assembly 30.

[0027] The ruler body 10 , the pendulum assembly 20 and the angle measuring assembly 30 cooperate with each other. When the ruler body 10 is placed against a wall surface, the inclination angle of the wall can be measured by cooperating with the pendulum assembly 20 and the angle measuring assembly 30 .

[0028] See also Figure 1 , Figure 2 and Figure 5, a hand-held part 110 is provided on the ruler body 10. The pendulum assembly 20 includes a U-shaped bracket 210, a winding part 220 and a plumb bob 230. The bracket 210 is fixed to one end of the ruler body 10, and the winding part 220 is installed on the bracket 210 to wind and adjust the height of the plumb bob 230. The angle measurement assembly 30 includes a back plate 310, an angle ruler 320 and a laser emitter 340. The back plate 310 is fixedly arranged with the bracket 210, the angle ruler 320 is installed on the back plate 310, a shaft 330 is rotatably arranged on the back plate 310, and the laser emitter 340 is installed on the shaft 330. Among them, the laser emitter 340 can be a laser pen.

[0029] Hold the ruler body 10 with one hand through the hand-held part 110 and place the ruler body 10 against a vertical wall. With the other hand, hang the plumb bob 230 under the winding part 220 close to the ground (or close to the wall, when the wall is greater than 90 degrees). Start the laser emitter 340. Initially, the light emitted by the laser emitter 340 is parallel to the plumb bob 230. At this time, the angle indicated by the angle ruler 320 is 0 degrees. Rotate the laser emitter 340 on the shaft 330 so that the light emitted by the laser emitter 340 is parallel to the wall. At this time, the offset angle of the laser emitter 340 observed by the angle ruler 320 is the inclination angle of the wall. That is, the wall verticality detection device can detect the approximate inclination angle of the wall, which is more accurate than the traditional vertical ruler detection.

[0030] Specifically, see Figure 1 A level bubble 120 which is perpendicular to the ruler body 10 is installed on the ruler body 10. The ruler body 10 is clamped on the wall. The level bubble 120 can be used to roughly understand whether the wall is in a vertical position. If the wall is offset, the square plumb line 230 can be used for accurate measurement.

[0031] In the above specific implementation, please refer to Figure 3 The winding part 220 includes a winding disc 221. The winding disc 221 is rotatably arranged inside the bracket 210, and a knob 222 is arranged at one end of the winding disc 221. The winding disc 221 winds up the line 223, and the bottom end of the line 223 is connected to the line sinker 230. Turning the knob 222 drives the winding disc 221 to rotate and retract the line 223, that is, retract and adjust the height of the line sinker 230.

[0032] For specific settings, see Figure 3 and Figure 4The inner top wall of the bracket 210 is provided with a limiting portion 240 connected with the side edge of the winding disk 221. The limiting portion 240 includes a roller 241 and an L-shaped support rod 242. The roller 241 is rotatably arranged at the end of the support rod 242, and a spring 243 is arranged between the support rod 242 and the inner top wall of the bracket 210 at the point where the roller 241 is connected with the side edge of the winding disk 221. In the process of rotating the knob 222 to drive the winding disk 221 to rotate and release the wire rope 223, the spring 243 in the limiting portion 240 presses the L-shaped support rod 242 and the roller 241. There is a strong friction force between the roller 241 and the winding disk 221. When the winding and releasing of the wire rope 223 is stopped, the winding disk 221 will not rotate due to the gravity of the line sinker 230.

[0033] Furthermore, a groove 246 is provided on the top wall of the bracket 210, and the top of the spring 243 is inserted into the groove 246. A positioning hole 247 that runs through the bracket 210 is provided at the bottom of the groove 246, and a positioning rod 245 that slides inside the positioning hole 247 is connected to the top of the support rod 242, and the spring 243 is sleeved outside the positioning rod 245. The positioning rod 245 and the positioning hole 247 are arranged to ensure that the spring 243 will not deviate during compression or relaxation. The limiting part 240 also includes an anti-slip sleeve, which is fixedly sleeved on the outside of the roller 241, so that there is greater friction between the roller 241 and the winding disk 221.

[0034] The working principle of the wall verticality detection device is as follows: when in use, one hand holds the ruler body 10 through the hand-held part 110 and places the ruler body 10 against a vertical wall. The other hand suspends the plumb bob 230 under the winding part 220 close to the ground in the air. Start the laser emitter 340. Initially, the light emitted by the laser emitter 340 is parallel to the plumb bob 230. At this time, the angle indicated by the angle ruler 320 is 0 degrees. Rotate the laser emitter 340 on the shaft 330 so that the light emitted by the laser emitter 340 is parallel to the wall. At this time, the offset angle of the laser emitter 340 observed by the angle ruler 320 is the inclination angle of the wall. That is, the wall verticality detection device can detect the approximate inclination angle of the wall, which is more accurate than the traditional vertical ruler detection.

[0035] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
