Description

Technical Field

[0001] The utility model relates to the technical field of pointing instrument brackets, in particular to a laser pointing instrument bracket for mine surveying. Background Technique

[0002] A laser pointing instrument is an instrument that uses the principle of laser beam orientation to indicate the construction direction of roadways and tunnels. It is divided into two types: roadway pointing instrument and laser plummet. A laser pointing instrument consists of a laser, an optical system, a power supply, and an installation and adjustment mechanism. During the use of the pointing instrument, a bracket is required to support and stabilize the laser pointing instrument.

[0003] When the existing pointing instrument bracket is in use, it is usually combined with a tripod to support and stabilize the pointing instrument. During the use process, in order to match the height of the staff for convenient use, the bracket usually needs to be adjusted in multiple places to adjust the use height of the bracket. The process is relatively troublesome and affects work efficiency, resulting in poor results during actual operation. Content of the Utility Model

[0004] The purpose of the utility model is to provide a laser pointing instrument bracket for mine surveying. By pushing the push rod, the two moving rods slide on their respective fixed blocks. During the movement of the push rod, the two springs are compressed, thereby driving the moving block between the two connecting blocks to move, so that the clamping block quickly disengages from the clamping groove, facilitating the rapid adjustment of the use height of the mounting plate. With the rebound of the spring, the clamping block quickly docks with the clamping groove to lock the adjusting rod, facilitating the adjustment of the use height of the bracket and improving work efficiency.

[0005] To achieve the above object, the utility model provides the following technical solution: A laser pointing instrument bracket for mine surveying, including a bottom plate.

The two ends of the spring 23 are respectively fixedly connected to the fixed block 21 and the push rod 22. By the push of the push rod 22, the two moving rods 20 move on their respective corresponding fixed blocks 21, so that the push rod 22 squeezes the spring 23, thereby enabling the two connecting blocks 19 to drive the card block 17 on the moving block 18 to disengage from the card slot 16, causing the adjusting rod 13 to move upward. When moving to an appropriate height, the push rod 22 is released, and the two springs 23 quickly rebound, causing the card block 17 to be stuck in the corresponding card slot 16. A rotating groove 31 is opened on the upper end surface of the stabilizing plate 14. A damping ring 32 is fixedly connected to the inner wall of the rotating groove 31.

A rubber pad 81 is fixedly connected to the lower end surface of the supporting block 63.The use of the three rubber pads 81 can generate a large frictional force between the rubber pads 81 and the ground, thus ensuring the sufficient stability of the bottom plate 1 and preventing random displacement.

[0036] The working principle and usage process of the present utility model: When in use, first, move the bracket to the position where it is needed. Cooperate with the sequential screwing of the three rotating sleeves 62 and the screw rod 61 to adjust the flatness of the bottom plate 1. Then, by pushing the push rod 22, the push rod 22 squeezes the two springs 23, causing the two moving rods 20 to drive the moving block 18 between the two connecting blocks 19 to move, so that the clamping block 17 on the moving block 18 disengages from the clamping groove 16, causing the adjusting rod 13 to move upward. When the adjusting rod 13 is lifted to an appropriate height, release the push rod 22, and the two springs 23 quickly rebound, causing the clamping block 17 to be stuck in the corresponding clamping groove 16, thereby fixing the adjusting rod 13. Then, install the laser pointer on the mounting plate 15 to achieve the usage process of the entire mine survey laser pointer bracket.
