Detailed Implementation
[0022] 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.
[0023] In practical implementation: such as Figures 1-5 As shown, a distance measuring device for construction engineering supervision includes a bracket 100 and a laser rangefinder 200 mounted on top of it; it also includes an adjustment mechanism 300, which is disposed at the bottom of the laser rangefinder 200 and used to adjust its position and distance measuring angle; wherein, the adjustment mechanism 300 includes an adjustable mounting frame 310, a movable plate 320 and a rotating disk 330 mounted on the bottom of the laser rangefinder 200, the movable plate 320 is movably connected to the interior of the mounting frame 310, a ball bearing 400 is provided between the mounting frame 310 and the bracket 100, and the rotating disk 330 is rotatably connected to the movable plate 320.
[0024] like Figure 3 and Figure 4 As shown, the adjustment mechanism 300 also includes two sliding plates 340. Rotating rods 321 are installed on both sides of the movable plate 320. One end of the rotating rod 321 passes through and is rotatably connected to the outside of the sliding plate 340.
[0025] Before the ranging operation, the user can install the support 100 to the appropriate position on the ranging site, and then level and lock the mounting frame 310 on the ball 400. Then, the user can adjust the laser range finder 200 according to the use requirements. When the position needs to be adjusted, the user can pull the movable plate 320, move it on the mounting frame 310 through the sliding plate 340, change the position, and also rotate the rotating disc 330 to change the ranging angle of the laser range finder 200 at different positions, and also rotate the movable plate 320 by 90 degrees, 180 degrees and 270 degrees to change the ranging direction. During the rotation, the rotating rod 321 moves along, and then the rotating rod 321 is locked.
[0026] As shown in Figure 1 and Figure 2 , the mounting frame 310 is installed with a traction rope at the four corners of the bottom, and the traction rope is installed with a counterweight cone 311 at one end. The center of gravity of the laser range finder 200, the ball 400 and the support 100 is coincident.
[0027] The counterweight cone 311 at the bottom of the traction rope can make the mounting frame 310 naturally level by gravity, and since the center of gravity of the laser range finder 200, the ball 400 and the support 100 is coincident, the laser range finder 200 can be in a horizontal state.
[0028] As shown in Figure 4 , the outer side of the sliding plate 340 is installed with a fixed plate, the inner side of the fixed plate is slidably connected with a plug rod 341, the outer side of the plug rod 341 is sleeved with a spring 342, the spring 342 is fixedly installed between the plug rod 341 and the fixed plate, and the outer side of the rotating rod 321 is provided with four insertion holes matched with the plug rod 341.
[0029] The user can pull the plug rod 341 in advance, and then after the rotating rod 321 is rotated in place, the user can release the plug rod 341, so that the spring 342 drives the plug rod 341 to reset and insert into the corresponding insertion hole, to complete the limiting of the rotating rod 321.
[0030] As shown in Figure 3 , the outer side of the rotating disc 330 and the outer side of the movable plate 320 are embedded with a group of magnets 331, and the opposite sides of adjacent two magnets 331 are magnetically connected.
[0031] After the user rotates the rotating disc 330 to adjust the ranging angle, the magnets 331 at the corresponding positions can be adsorbed to each other, so as to ensure the stability of the rotating disc 330 and the laser range finder 200.
[0032] As shown in Figure 2 and Figure 5As shown, two piston tubes 110 are installed on the top of the bracket 100. A piston plate 120 is slidably connected inside the piston tube 110. A hinge rod 130 is provided between the piston plate 120 and the mounting bracket 310. An exhaust pipe 140 is installed on the piston tube 110.
[0033] During the natural leveling process, the hinge rod 130 will drive the piston plate 120 to follow the movement. At this time, the gas in the piston tube 110 will interact with the outside through the exhaust pipe 140. After the leveling is completed, the exhaust pipe 140 can be closed, so that the piston plate 120 and the hinge rod 130 cannot move, thereby achieving a locking effect and ensuring the stability of the laser rangefinder 200.
[0034] like Figure 5 As shown, a solenoid valve is installed on the outside of the exhaust pipe 140.
[0035] Users can control the opening and closing of the exhaust pipe 140 by operating the solenoid valve.
[0036] Working Principle: Before performing distance measurement, the user can install the bracket 100 in a suitable position at the distance measurement site. The counterweight cone 311 at the bottom of the traction rope allows the mounting bracket 310 to be naturally leveled under its own weight. Since the center of gravity of the laser rangefinder 200, the ball bearing 400, and the bracket 100 coincides, the laser rangefinder 200 is kept horizontal. During this natural leveling process, the hinge rod 130 drives the piston plate 120 to move accordingly. At this time, the gas inside the piston tube 110 interacts with the outside through the exhaust pipe 140. After leveling, the exhaust pipe 140 can be closed, preventing the piston plate 120 and the hinge rod 130 from moving, thus achieving a locking effect and ensuring the stability of the laser rangefinder 200. The user can then adjust the laser rangefinder 200 according to their needs. For example, when adjusting its position, the user can move the movable plate 320 and slide the plate 340 to adjust its position. The device moves on the mounting bracket 310 to change its position. Simultaneously, the rotating disk 330 can be rotated to change the ranging angle of the laser rangefinder 200 at different positions. The movable plate 320 can also be rotated 90 degrees, 180 degrees, and 270 degrees to change the ranging orientation. The user can pre-pull the insertion rod 341; as the movable plate 320 rotates, the rod 321 follows. After the rod 321 reaches its final position, the user can release the insertion rod 341, causing the spring 342 to drive it back to its original position and insert it into the corresponding hole, thus limiting the rotation of the rod 321. The entire device can level the laser rangefinder 200, ensuring its stability during use and reducing tilting, thereby guaranteeing ranging accuracy. Furthermore, it can be used for ranging at different positions and angles according to user needs, making it more practical.
[0037] Furthermore, it should be understood that although the specification is described in terms of embodiments, not every embodiment includes every feature or implementation described herein. The specification can include implicit combinations of explicitly mentioned features and / or implicit combinations of implicitly mentioned features. Such combinations are also expressly included within the scope of the specification and an embodiment.
