Description

Technical Field

[0001] The utility model relates to the technical field of laser distance measuring devices, and more specifically to a laser distance measuring device for mines. Background Art

[0002] In mines, laser distance measuring devices are often used to accurately and quickly measure the distance and height of tunnels, working faces, mining faces, etc. During the measurement process, a worker usually holds a laser distance measuring device at one of the measurement points and aims the laser distance measuring device at another measurement point. The laser distance measuring device emits a pulsed laser beam, which is transmitted to the measured point and then reflected to the laser distance measuring device. The distance between the two measurement points is measured by the time the pulsed laser beam is received. Compared with traditional tape measures, it is more convenient to use and the measurement results are more accurate.

[0003] At present, during the measurement process in mines, workers sometimes need to hold the laser distance measuring device close to the wall to maintain horizontal measurement when operating it. However, the walls in mines are not all flat. Therefore, during the measurement process, workers are often required to search and adjust the position many times to reduce the deviation. The operation is more troublesome and not convenient to use. In addition, operating the laser distance measuring device to search and adjust the position back and forth along the wall will also cause wear and tear on the surface, causing damage to it and resulting in poor use effect. Therefore, there is an urgent need to improve the technology of the laser distance measuring device to improve this equipment.

[0004] Therefore, the utility model provides a laser distance measuring device for mines. Utility Model Content

[0026] See also Figure 1-4A laser distance measuring device for mines comprises a laser distance meter 1, a display panel 2 is embedded and installed on the laser distance meter 1, and a plurality of function buttons 3 are installed on the upper end of the laser distance meter 1, a laser transmitter 4 is embedded and installed on the left end of the laser distance meter 1, a sleeve 6 in contact with the outer end of the laser distance meter 1 is provided, and a clamping mechanism 9 is installed between the sleeve 6 and the laser distance meter 1, a pair of rotating rods 7 are fixedly connected to the outer end of the sleeve 6, and a wall-attached outer frame 5 is rotatably connected between the outer ends of the pair of rotating rods 7, a fine-tuning limit mechanism 8 is installed between the wall-attached outer frame 5 and the rotating rod 7, a plurality of fixed suction cups 10 are embedded and installed on the lower end of the wall-attached outer frame 5, a pair of fine-tuning limit mechanisms 8 include a pulling plate 801 located outside the wall-attached outer frame 5, one end of the pulling plate 801 close to the rotating rod 7 is fixedly connected to a limit rod 802, a limit groove 803 is cut at the outer end of the rotating rod 7, and the limit rod 802 matches the limit groove 803, Two pairs of built-in straight tubes 804 are embedded and installed at the outer end of the wall-attached outer frame 5, and the inner part of the built-in straight tubes 804 is slidably connected with T-shaped rods 805. The outer ends of the pair of T-shaped rods 805 are sleeved with telescopic springs 806, and the two ends of the telescopic springs 806 are respectively fixedly connected to the T-shaped rods 805 and the built-in straight tubes 804. The inner walls of the pair of built-in straight tubes 804 are drilled with through holes, and the ends of the pair of T-shaped rods 805 close to the pulling plate 801 pass through the through holes and are connected to the pulling plate 801. The plate 801 is fixedly connected, and the locking mechanism 9 includes two pairs of plug plates 901 in contact with the outer end of the casing 6. The ends of the two pairs of plug plates 901 that are close to each other are fixedly connected with elastic convex plug rods 902. Two pairs of holes 903 are drilled at the outer end of the casing 6. Two pairs of slots 904 are drilled at the outer end of the laser rangefinder 1, and the holes 903 are connected to the slots 904. The ends of the two pairs of elastic convex plug rods 902 that are close to each other pass through the holes 903 and extend into the slots 904.

[0027] During the use of this solution, first take the laser rangefinder 1 and place it in the casing 6, then take the two pairs of plug plates 901 in the locking mechanism 9, drive the elastic protruding plug rod 902 to be inserted into the slot 904 along the socket 903, and limit and fix it, so as to realize the convenient installation between the movable casing 6 and the laser rangefinder 1. When disassembling, pull the plug plate 901 to move outward, drive the elastic protruding plug rod 902 to move away from the slot 904 and the socket 903 in turn, so as to realize the convenient disassembly between the casing 6 and the laser rangefinder 1, which is simple to operate. Then operate the wall-attached outer frame 5 to contact the wall surface in the mine, so that multiple fixed suction cups 10 are adsorbed and fixed to the wall surface. If the wall surface is uneven, the wall-attached outer frame 5 cannot be in a horizontal state after contacting and fitting with it, and the corresponding laser rangefinder 1 is also not in a horizontal state. In order to reduce To measure the deviation, the staff squeezes a pair of pulling plates 801 in the fine-tuning limit mechanism 8 to move apart, driving the limit rod 802 to separate from the limit groove 803, canceling the fixation of the rotating rod 7, and then moves the laser rangefinder 1 to slowly adjust the angle as the rotating rod 7 rotates until it is in a horizontal state. After adjusting to the horizontal state, release the squeezing of the pulling plate 801, so that the pulling plate 801 is reset under the elastic action of the telescopic spring 806, driving the limit rod 802 to extend into the limit groove 803 for limit fixation, so that the laser rangefinder 1 remains stable after being adjusted to the horizontal state, so as to facilitate subsequent stable measurement and enhance the measurement effect. In addition, there is no need for the staff to hold the laser rangefinder 1 and adjust the position back and forth along the wall, which reduces the operation trouble and the wear on the surface of the laser rangefinder 1 and extends its service life.

[0028] During use of the present solution, when the angle of the laser rangefinder 1 needs to be adjusted, the pair of pulling plates 801 are squeezed to move apart, driving the limit rod 802 to separate from the limit groove 803, releasing the fixation of the rotating rod 7, and the corresponding T-shaped rod 805 also moves with the pulling plate 801, and squeezes the telescopic spring 806 for compression. After the adjustment is completed, the squeezing of the pair of pulling plates 801 is released, prompting the pair of pulling plates 801 to move toward each other under the elastic action of the telescopic spring 806, and driving the limit rod 802 to re-extend into the limit groove 803 for limit fixation, so that the laser rangefinder 1 remains stable after being adjusted to a horizontal state, so as to facilitate subsequent stable measurement and enhance the measurement effect. In addition, there is no need for the staff to hold the laser rangefinder 1 and adjust the position back and forth along the wall, which reduces the trouble of operation and the wear on the surface of the laser rangefinder 1 and extends its service life.

[0030] During use, the present invention realizes sliding assistance and position limiting regulation during the movement of the T-shaped rod 805 by setting the slide groove 8051, so that the T-shaped rod 805 can move stably along the slide groove 8051 during the movement and is not prone to deviation.

[0031] During the use of this solution, during the installation of the laser rangefinder 1 and the casing 6, the staff takes two pairs of elastic convex plug rods 902 in turn and inserts them into the socket 903, and the convex parts thereof are deformed and contracted under the extrusion action until they are in contact with the inner wall of the socket 903, and continue to move while maintaining contact with the inner wall of the socket 903 until they extend into the slot 904, and the convex parts of the elastic convex plug rods 902 are engaged with the slot 904 for position fixing, thereby realizing convenient installation between the casing 6 and the laser rangefinder 1, and when disassembling, the plug plate 901 is pulled outward to drive the elastic convex plug rods 902 to move away from the slot 904 and the casing 903 in turn, thereby realizing convenient disassembly between the casing 6 and the laser rangefinder 1.

[0032] See also Figure 1 A transparent protective film 201 is provided on the surface of the display panel 2, and an AS oleophobic and hydrophobic coating is provided on the surface of the transparent protective film 201.
