Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a laser measuring instrument for building construction. Background Technology

[0002] Laser measuring instruments emit laser beams to illuminate target objects and determine parameters such as the position, distance, and angle of the target objects by receiving the reflected signals from the laser beams.

[0003] The development of laser technology has greatly improved the accuracy of building construction. In building construction, laser measuring instruments can be used to measure parameters such as the levelness of the foundation and the verticality of the building. During the inspection, it is necessary to ensure the stability of the laser measuring instrument to avoid errors and ensure the quality of building construction. However, when using existing laser measuring instruments, they are often fixed to a tripod with bolts to ensure stability during the measurement process, which is inconvenient for installation and disassembly. Utility Model Content

[0004] The purpose of this utility model is to provide a laser measuring instrument for building construction, so as to solve the problem mentioned in the background art that when using laser measuring instruments, they are often fixed to a tripod with bolts to ensure stability during the measurement process, and the installation and disassembly are inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a laser measuring instrument for building construction, comprising a tripod, a connecting column rotatably connected to the surface of the tripod, an adjusting handle fixedly connected to the surface of the connecting column, a threaded rod threadedly connected to the surface of the connecting column, a fixed handle fixedly connected to the end of the threaded rod away from the connecting column, a limit block fixedly connected to the surface of the threaded rod, a circular groove formed inside the tripod, a placement platform fixedly connected to the surface of the connecting column, a laser rangefinder placed on the surface of the placement platform, a limiting plate rotatably connected to the interior of the placement platform, a connecting shaft fixedly connected to the surface of the limiting plate, a rotating handle fixedly connected to the surface of the connecting shaft, a cam fixedly connected to the end of the connecting shaft away from the limiting plate, a first clamping plate movably connected to the surface of the placement platform, a return spring fixedly connected to the surface of the first clamping plate, a second clamping plate fixedly connected to the end of the return spring away from the first clamping plate, a limit groove formed inside the placement platform, and a connecting groove formed on the surface of the placement platform.

[0006] Preferably, the connecting shaft is rotatably connected to the inside of the placement table via a rotating handle, the limiting plate is rotatably connected to the inside of the placement table via the connecting shaft, and the cam is rotatably connected to the inside of the placement table via the connecting shaft.

[0007] Preferably, the first clamping plate is movably connected to the surface of the placement table via a cam, and the second clamping plate is movably connected to the surface of the placement table via a cam.

[0008] Preferably, the reset springs are symmetrically distributed in two sets on the surface of the first clamping plate, and the limiting grooves are symmetrically distributed in two sets inside the placement platform. The first clamping plate is movably connected to the surface of the limiting grooves through the reset springs, and the second clamping plate is movably connected to the surface of the limiting grooves through the reset springs.

[0009] Preferably, the connecting slots are symmetrically distributed in two sets on the surface of the placement platform. The first clamping plate is connected to the surface of the laser rangefinder by a return spring, and the second clamping plate is connected to the surface of the laser rangefinder by a return spring. The laser rangefinder is fixedly connected to the surface of the placement platform by the first clamping plate.

[0010] Preferably, the tripod surface has a movable groove, the connecting column is rotatably connected to the tripod surface via an adjusting handle, and the placement platform is rotatably connected to the tripod surface via the connecting column.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By rotating the handle and connecting shaft, and connecting shaft and cam, the cam rotates. The connecting shaft rotates normally through the connection of the limiting plate and connecting shaft. Then, through the connection of the first clamping plate and limiting groove, and the connection of the second clamping plate and limiting groove, the cam rotates and connects with the first and second clamping plates, increasing the distance between the first and second clamping plates. At this time, the return spring deforms. Through the connection of the placement platform and laser rangefinder, the laser rangefinder can be placed between the first and second clamping plates. Through the connection of the first clamping plate and return spring, and the connection of the return spring and second clamping plate, the cam is rotated again to leave the surface of the first and second clamping plates. At this time, the return spring returns to its original state, driving the first and second clamping plates to return to their original state, so that the first and second clamping plates clamp and fix the laser rangefinder. Conversely, the laser rangefinder can be disassembled, achieving the effect of facilitating the installation and disassembly of the laser rangefinder.

[0014] 2. By connecting the fixed throttle and the threaded rod, rotating the fixed throttle can cause the threaded rod to move away from the surface of the connecting column. By connecting the limiting block and the circular groove, the movement of the threaded rod causes the limiting block to move inside the circular groove, thereby limiting the position of the threaded rod. Then, by connecting the connecting column and the adjusting handle, rotating the adjusting handle can adjust the working angle of the connecting column. Then, by connecting the threaded rod and the connecting column, rotating the fixed throttle connects the threaded rod and the connecting column, fixing the tilt angle of the connecting column, thereby determining the working angle of the laser rangefinder, achieving the effect of adjusting the working angle of the laser rangefinder.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A laser measuring instrument for building construction includes a tripod 1 for mounting a laser rangefinder 11. A connecting column 3 is rotatably connected to the surface of the tripod 1 for connecting a platform 2. An adjusting handle 31 is fixedly connected to the surface of the connecting column 3 for rotating the connecting column 3. A threaded rod 32 is threadedly connected to the surface of the connecting column 3 for fixing the position of the connecting column 3. A fixed handle 33 is fixedly connected to the end of the threaded rod 32 away from the connecting column 3 for rotating the threaded rod 32. A limit block 34 is fixedly connected to the surface of the threaded rod 32 for limiting the movement distance of the threaded rod 32. A circular groove 35 is formed inside the tripod 1 for the movement of the limit block 34. The platform 2 is fixedly connected to the surface of the connecting column 3 for placing the laser rangefinder 11. The laser rangefinder 11 is placed on the surface of the platform 2 for building distance measurement. A limiting plate 21 is rotatably connected inside the platform 2 for limiting the rotation position of a connecting shaft 22. The connecting shaft 22 is fixedly connected to the surface of the limiting plate 21 for connecting the rotating shaft 22. A handle 23 and a cam 24 are fixedly connected to the surface of the connecting shaft 22 for rotating the connecting shaft 22. A cam 24 is fixedly connected to the end of the connecting shaft 22 away from the limiting plate 21 for changing the connection with the first clamping plate 25 and the second clamping plate 27 by rotating itself, thereby changing the position of the first clamping plate 25 and the second clamping plate 27. The surface of the placement platform 2 is movably connected to the first clamping plate 25 for abutting against one side of the laser rangefinder 11. A return spring 26 is fixedly connected to the surface of the first clamping plate 25 for connecting the first clamping plate 25 and the second clamping plate 27 and for driving both to return to their original positions. The end of the return spring 26 away from the first clamping plate 25 is fixedly connected to the second clamping plate 27 for abutting against the other side of the laser rangefinder 11. A limiting groove 28 is opened inside the placement platform 2 for the lower ends of the first clamping plate 25 and the second clamping plate 27 to move inside the placement platform 2. A connecting groove 29 is opened on the surface of the placement platform 2 for the upper ends of the first clamping plate 25 and the second clamping plate 27 to move on the surface of the placement platform 2.

[0024] Furthermore, the connecting shaft 22 is rotatably connected to the inside of the placement platform 2 via the rotating handle 23, the limiting plate 21 is rotatably connected to the inside of the placement platform 2 via the connecting shaft 22, and the cam 24 is rotatably connected to the inside of the placement platform 2 via the connecting shaft 22. By rotating the rotating handle 23, the connecting shaft 22 and the cam 24 can be driven to rotate inside the placement platform 2. At the same time, the setting of the limiting plate 21 restricts the rotation position of the connecting shaft 22 and the cam 24.

[0025] Furthermore, the first clamping plate 25 is movably connected to the surface of the placement platform 2 via the cam 24, and the second clamping plate 27 is movably connected to the surface of the placement platform 2 via the cam 24. After the cam 24 rotates, it changes the connection with the first clamping plate 25 and the second clamping plate 27. The cam 24 pushes the first clamping plate 25 and the second clamping plate 27 apart, so that the distance between them increases, and then the laser rangefinder 11 can be placed between the first clamping plate 25 and the second clamping plate 27.

[0026] Furthermore, the return springs 26 are symmetrically distributed in two sets on the surface of the first clamping plate 25, which are used to connect the first clamping plate 25 and the second clamping plate 27 while ensuring their balance. The limiting grooves 28 are symmetrically distributed in two sets inside the placement platform 2, one set for the movement of the first clamping plate 25 and the other set for the movement of the second clamping plate 27. The first clamping plate 25 is movably connected to the surface of the limiting grooves 28 through the return springs 26 and the second clamping plate 27. After the cam 24 is rotated to push the first clamping plate 25 and the second clamping plate 27 apart, the return spring 26 will deform. Rotating the cam 24 again will cause the cam 24 to leave the surface of the first clamping plate 25 and the second clamping plate 27. The return spring 26 will then drive the first clamping plate 25 and the second clamping plate 27 to reset in order to restore their original shape.

[0027] Furthermore, the connecting grooves 29 are symmetrically distributed in two sets on the surface of the placement platform 2. One set is used for the movement of the first clamping plate 25, and the other set is used for the movement of the second clamping plate 27. The first clamping plate 25 is connected to the surface of the laser rangefinder 11 by abutting through the return spring 26, and the second clamping plate 27 is connected to the surface of the laser rangefinder 11 by abutting through the return spring 26. The laser rangefinder 11 is fixedly connected to the surface of the placement platform 2 by the first clamping plate 25. When the return spring 26 returns to its original state, it drives the first clamping plate 25 and the second clamping plate 27 to reset. The first clamping plate 25 and the second clamping plate 27 will clamp the laser rangefinder 11 to limit the position of the laser rangefinder 11 and fix the laser rangefinder 11 on the surface of the placement platform 2.

[0028] Furthermore, the surface of the tripod 1 is provided with a movable groove for the connecting column 3 to rotate. The connecting column 3 is rotatably connected to the surface of the tripod 1 via the adjusting handle 31. The placement platform 2 is rotatably connected to the surface of the tripod 1 via the connecting column 3. Rotating the adjusting handle 31 causes the connecting column 3 to rotate on the surface of the tripod 1, so that the placement platform 2 can rotate on the surface of the tripod 1, thereby changing the measuring angle of the laser rangefinder 11 in order to measure the distance at the tilted position.

[0029] Furthermore, the threaded rod 32 is rotatably connected to the surface of the connecting post 3 via the fixed throttle 33, the limiting block 34 is movably connected to the inside of the circular groove 35 via the threaded rod 32, and the connecting post 3 is fixedly connected to the surface of the tripod 1 via the threaded rod 32. Rotating the fixed throttle 33 drives the threaded rod 32 to rotate, which can tighten the threaded rod 32 onto the surface of the connecting post 3, thereby fixing the rotation angle of the connecting post 3. By rotating the fixed throttle 33 to unscrew the threaded rod 32, the limiting block 34 moves at the circular groove 35, restricting the movement position of the threaded rod 32 and preventing the threaded rod 32 from falling off the surface of the tripod 1.

[0030] Working principle: When using tripod 1, first rotate handle 23, which drives connecting shaft 22 and cam 24 to rotate inside the platform 2. After cam 24 rotates, it pushes the first clamp 25 and the second clamp 27 apart, increasing the distance between them. At this time, return spring 26 deforms, and then the laser rangefinder 11 can be placed between the first clamp 25 and the second clamp 27. Rotate cam 24 again, causing cam 24 to leave the surface of the first clamp 25 and the second clamp 27. Return spring 26 returns to its original state, causing the first clamp 25 and the second clamp 27 to return to their original state. The first clamp 25 and the second clamp 27 will clamp the laser rangefinder 11, limiting its position and fixing the laser rangefinder 11 to the surface of the platform 2. After fixing the laser rangefinder 11, during use, the laser irradiation angle of the laser rangefinder 11 needs to be adjusted to detect the distance at the tilted position. By rotating the fixing handle 33, the threaded rod 32 is moved away from the surface of the connecting column 3, and the limiting block 34 moves in the circular groove 35 to restrict the movement of the threaded rod 32 and prevent the threaded rod 32 from falling off the surface of the tripod 1. Then, rotating the adjusting handle 31 drives the connecting column 3 to rotate on the surface of the tripod 1, so that the placement platform 2 can rotate on the surface of the tripod 1, thereby changing the measuring angle of the laser rangefinder 11. Then, rotating the fixing handle 33 drives the threaded rod 32 to rotate, which can tighten the threaded rod 32 on the surface of the connecting column 3, thereby fixing the rotation angle of the connecting column 3 and determining the operating angle of the laser rangefinder 11.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
