Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, and in particular to a laser rangefinder positioning device. Background Technology

[0002] A laser rangefinder is an instrument that accurately measures the distance to a target by modulating a laser beam with a specific parameter. A pulsed laser rangefinder emits a single or a series of short pulsed laser beams towards the target. A photoelectric element receives the reflected laser beam, and a timer measures the time from emission to reception to calculate the distance from the rangefinder to the target. To prevent inaccurate measurements due to handheld shaking or tilting caused by human error, suction cups or support frames are now commonly used to attach the rangefinder to a wall or support it on the ground. However, using suction cups or support frames for fixing the rangefinder prevents vertical or horizontal adjustments without moving the suction cups or support frames. This necessitates repeated adjustments by the operator, which can lead to displacement of the suction cups or support frames and affect the measurement accuracy. Utility Model Content

[0003] This utility model discloses a laser rangefinder positioning device, which solves the problem that when adjusting the position of the laser rangefinder, the operator needs to adjust the position of the suction cup or support frame, which can easily cause the position of the suction cup or support frame to shift, affecting the ranging effect.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A laser rangefinder positioning device includes a positioning plate with a suction cup fixed on it. A first motor is provided on the side of the positioning plate away from the suction cup. A connecting frame is fixed on the shaft of the first motor. A movable plate that can reciprocate toward both ends of the connecting frame is slidably connected inside the connecting frame. A second motor is provided on the connecting frame, and a first lead screw that is threadedly connected to the movable plate is fixed on the shaft of the second motor. The movable plate has a fixed plate and a limiting plate that are relatively distributed and used to clamp the laser rangefinder.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] The positioning plate is attached to the wall by suction cups. The first motor drives the connecting frame to be in a vertical or horizontal position, and the second motor drives the moving plate to move the laser rangefinder up and down or horizontally. This allows the laser rangefinder to be moved without adjusting the position of the positioning plate. This invention allows the laser rangefinder to be raised, lowered, or moved horizontally without moving the positioning plate. The operation is simple and quick, and it eliminates the problem of laser rangefinder displacement caused by repeated disassembly of the positioning plate, thus ensuring the accuracy of the laser rangefinder's distance measurement.

[0012] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0013] like Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a laser rangefinder positioning device, including a positioning plate 1, a suction cup 2 fixed on the positioning plate 1, a first motor 3 on the side of the positioning plate 1 away from the suction cup 2, a connecting frame 31 fixed on the rotating shaft of the first motor 3, a movable plate 5 slidably connected inside the connecting frame 31 and capable of reciprocating toward both ends of the connecting frame 31, a second motor 4 on the connecting frame 31, a first lead screw 41 threadedly connected to the movable plate 5 fixed on the rotating shaft of the second motor 4; the movable plate 5 is provided with a fixed plate 51 and a limiting plate 52 that are relatively distributed and used to clamp the laser rangefinder. After the positioning plate 1 is attached to the wall by suction cup 2, the connecting frame 31 is made to be in a vertical position. Then, the laser rangefinder is placed on the moving plate 5, and the fixing plate 51 and the limiting plate 52 cooperate to clamp and fix the laser rangefinder. Then, according to the actual situation, when it is necessary to raise or lower the laser rangefinder, the second motor 4 is started to drive the first lead screw 41 to rotate, so that the moving plate 5 moves the laser rangefinder up or down. When it is necessary to move the laser rangefinder horizontally, the first motor 3 is started to drive the connecting frame 31 to rotate. After the connecting frame 31 is in a horizontal position, the second motor 4 is started to move the moving plate to move the laser rangefinder, so as to change the position of the laser rangefinder. Moreover, the adjustment of the laser rangefinder's position is not limited to the connecting frame 31 being in a horizontal or vertical position. The position of the laser rangefinder can also be adjusted when the connecting frame 31 is in an inclined position. Both the first motor 3 and the second motor 4 are servo motors.

[0014] like Figure 1 , Figure 2 and Figure 3 As shown, a threaded screw 511 passes through the fixed plate 51, and a connecting plate 521 that is slidably connected to the moving plate 5 is fixed on the limiting plate 52. The connecting plate 521 is rotatably connected to the end of the screw 511. Rotating the screw 511 causes the connecting plate 521 to move the limiting plate 52 toward the fixed plate 51. The outer wall of the connecting frame 31 is provided with scale values, and an indicator plate 53 covering the scale values ​​is fixed on the moving plate 5. A first storage battery 311 is fixed on the connecting frame 31. The fixed plate 51 is fixed to the back of the moving plate 5, and the top of the moving plate 5 has an opening for the connecting plate 521 to pass through. The connecting plate 521 is slidably connected in the opening. The laser rangefinder is placed on the top of the moving plate 5, and the back of the laser rangefinder (towards) Figure 1The laser rangefinder (as shown in the diagram) contacts the fixed plate 51, and then the screw 511 is rotated to make the connecting plate 521 move the limiting plate 52 closer to the fixed plate 51, so as to hold the front of the laser rangefinder against it and complete the fixation of the laser rangefinder; and rubber pads are fixed on the opposite surfaces of the fixed plate 51 and the limiting plate 52 to increase the friction of the laser rangefinder and better fix the laser rangefinder; when the moving plate 5 moves the indicator plate 53, the operator can check the moving distance of the laser rangefinder according to the scale value on the connecting frame 31, and the first battery 311 can supply power to the second motor 4.

[0015] like Figure 1 As shown, the positioning plate 1 is L-shaped. A fixing frame 6 is provided on the inner wall of the positioning plate 1 away from the suction cup 2. A moving block 61 is slidably connected to the inner side of the fixing frame 6. A second lead screw 62, threadedly connected to the moving block 61, is rotatably connected to the inner side of the fixing frame 6. The main body of the first motor 3 is fixed on the moving block 61. A limiting rod 8, which is slidably connected to the fixing frame 6, is fixed on the inner wall of the positioning plate 1 near the suction cup 2. A slide rail 9 is provided on the inner wall of the positioning plate 1 away from the suction cup 2. A slider that matches the slide rail 9 is fixed on the fixing frame 6. A second storage battery 63 is fixed on the fixing frame 6. The limiting rod 8 is I-shaped, and both ends of the limiting rod 8 are made of magnetic material. The fixing frame 6 is located between the two ends of the limiting rod 8, and magnets 7 corresponding to the two ends of the limiting rod 8 are fixed on both sides of the fixing frame 6. When the connecting frame 31 is in a vertical position, and both the height and horizontal position of the laser rangefinder need to be adjusted, the second lead screw 62 can be manually rotated to move the moving block 61 and drive the first motor 3 horizontally, thus adjusting the horizontal position of the laser rangefinder. When the connecting frame 31 is in a horizontal position, moving the moving block 61 can further extend the horizontal movement distance of the laser rangefinder. There are at least two limiting rods 8. When the laser rangefinder is not in use, the fixed frame 6 can be slid to move the connecting frame 31 to the inside of the positioning plate 1, reducing the overall size of the device for easier carrying and also protecting the connecting frame 31. When the laser rangefinder needs to be used, the magnet 7 on the right side of the fixed frame 6 contacts the right end of the limiting rod 8 (to...). Figure 1 (as shown in the diagram), so that the magnet 7 attracts the right end of the limiting rod 8, and fixes the fixing frame 6; the second battery 63 can supply power to the first motor 3.

[0016] like Figure 1As shown, a fixing block 11 is fixed on the inner wall of the positioning plate 1 away from the suction cup 2. A threaded screw 111 passes through the fixing block 11. The positioning plate 1 has a through hole that matches the screw 111. When the positioning plate 1 needs to be placed on a hard surface, the side of the positioning plate 1 away from the suction cup 2 can be in contact with the ground, so that the connecting frame 31 is in a horizontal state. When the height of the laser rangefinder needs to be adjusted, the second lead screw 62 can be rotated to adjust the height of the laser rangefinder. When the ground is soft or muddy, the screw 111 can be rotated so that the tip of the screw 111 extends outside the positioning plate 1, so that the screw 111 can be inserted into the soil to fix the positioning plate 1. When the screw 111 is not needed, the tip of the screw 111 can be placed in the threaded hole on the fixing block 11.
