[0023] This utility model provides the following technical solution: a device for measuring interior dimensions of a building, please refer to [link / reference]. Figures 1-4 The device includes a positioning column 1, with a rubber pad A101 at its bottom. A rotating shaft 2 is rotatably connected to the upper inner wall of the positioning column 1, and a handwheel 201 is installed at the bottom of the rotating shaft 2. A telescopic column 202 is slidably connected to the top of the positioning column 1, and the inside of the telescopic column 202 is threadedly connected to the outer wall of the rotating shaft 2. A rubber pad B203 is provided at the top of the telescopic column 202. A guide rail 3 is installed below the front end face of the positioning column 1, and a positioning groove 301 is provided at the center of the front end face of the guide rail 3. Guide grooves 302 are provided on both sides of the outer wall of the guide rail 3. The positioning column 1 is the main support structure of the device. The bottom rubber pad A101 increases the friction with the ground to prevent the positioning column 1 from sliding and ensures initial placement stability. The rotating shaft 2 is rotatably connected to the upper inner wall of the positioning column 1. The bottom handwheel 201 makes it convenient for the operator to rotate the rotating shaft 2. The telescopic column 202, which is slidably connected to the top of the positioning column 1, is threadedly engaged with the rotating shaft 2. Rotating the handwheel 201 can drive the telescopic column 202 to rise and fall. The rubber pad B203 at the top of the telescopic column 202 can protect the indoor ceiling and enhance the friction with the ceiling, thereby improving the fixing effect of the positioning column 1.

[0024] A measuring component is installed above the front end face of the guide rail 3. The measuring component includes a positioning frame 4. Mounting seats 401 are installed on both outer walls of the positioning frame 4. A guide seat 402 is provided on one inner wall of the mounting seat 401. The outer wall of the guide seat 402 is slidably connected to the inside of the guide groove 302. A guide frame 403 is installed at the center of the front end face of the positioning frame 4. A guide post 404 is slidably connected inside the guide frame 403. A pull ring 405 is installed at one end of the guide post 404, which is located outside the guide frame 403. A positioning pin 40 is installed at the other end of the guide post 404. 6. The positioning pin 406 is located inside the guide frame 403. The outer wall of the positioning pin 406 is slidably connected to the inside of the positioning groove 301. A spring 407 is provided on the outer wall of the guide column 404. Slots 408 are provided on the front surface of the mounting base 401. A laser rangefinder 409 is slidably connected inside a set of slots 408. The guide rail 3 is installed below the front face of the positioning column 1. The positioning groove 301 provided by the guide rail 303 provides a positioning base for the positioning pin 406. The guide groove 302 cooperates with the guide seat 402 of the mounting base 401 to provide a stable trajectory for the lifting and lowering of the positioning frame 4 and prevent deviation. The guide frame 403 is fixed on the positioning frame 4 and provides sliding support for the guide column 404. The pull ring 405 at one end of the guide column 404 is convenient for the operator to pull. The positioning pin 406 at the other end cooperates with the positioning groove 301 to fix the positioning frame 4. The spring 407 on the outer wall of the guide column 404 can automatically reset when the pull ring 405 is released, pushing the positioning pin 406 into the positioning groove 301. The multi-directional slot 408 opened in the mounting base 401 can adapt to different angle measurement needs. After the laser rangefinder 409 is inserted into the slot 408, it can maintain a stable measurement state.

[0025] Working principle: When using this utility model, firstly, place the positioning column 1 in a corner or desired position of the indoor area to be measured, with the rubber pad A101 at the bottom of the positioning column 1 in contact with the ground to initially ensure stable placement; then rotate the handwheel 201 at the bottom of the rotating shaft 2. Since the rotating shaft 2 is threadedly connected to the telescopic column 202, and the telescopic column 202 is slidably connected to the inside of the top of the positioning column 1, the rotation of the handwheel 201 drives the rotating shaft 2 to rotate, thereby driving the telescopic column 202 to extend upward along the inner wall of the positioning column 1 until the rubber pad B203 at the top of the telescopic column 202 is tightly pressed against the top of the room, thus completing the installation and fixing of the positioning column 1 and providing a stable foundation for subsequent measurements. Secondly, when it is necessary to adjust the height of the measuring component to adapt to different measuring positions, the operator pulls the pull ring 405 at one end of the guide column 404 on the positioning frame 4. The guide column 404 slides along the inside of the guide frame 403, causing the positioning pin 406 at the other end to disengage from the corresponding positioning groove 301 on the guide rail 3. At this time, the spring 407 on the outer wall of the guide column 404 is compressed. Then, the positioning frame 4 is pushed, and the positioning frame 4 slides along the guide groove 302 of the guide rail 3 through the guide seats 402 on the two mounting seats 401. After adjusting to a suitable measuring height, the pull ring 405 is released, the spring 407 returns to its deformation, pushes the guide column 404 to reset, and the positioning pin 406 is reinserted into the positioning groove 301 of the corresponding height, thus fixing the positioning frame 4 after adjustment. Finally, according to the indoor measurement angle requirements, such as horizontal, vertical, or tilt angle, insert the laser rangefinder 409 into the corresponding slot 408 on the mounting base 401 of the positioning frame 4. The laser rangefinder 409 remains stable in the slot 408 without shaking or instability, ensuring accurate measurement data. At the same time, the operator does not need to hold the laser rangefinder 409 and can directly observe and record the measurement dimension data displayed by the laser rangefinder 409, achieving simultaneous stable measurement and convenient recording.
