Description

Technical Field

[0001] The utility model relates to the technical field of laser telescopes, and specifically relates to a main mounting plate of a lidar used for a telescope. Background Art

[0002] A lidar telescope is a device that uses laser technology to measure the distance and shape of an object. It emits laser pulses and receives the returned reflected light to accurately calculate the distance, size, and shape of the object. Lidar telescopes are commonly used in fields such as topographic mapping, forest monitoring, autonomous vehicle navigation, and three-dimensional modeling of buildings and structures.

[0003] The existing mounting frames for lidar and telescopes result in different ranging deviations. When the laser emission device is installed parallel to the telescope above the telescope, the ranging result is too far; conversely, when the laser emission device is installed parallel to the telescope below the telescope, the ranging result is too close. Summary of the Utility Model

[0004] The utility model aims to at least solve one of the technical problems existing in the prior art. For this purpose, the utility model provides a main mounting plate of a lidar used for a telescope, which solves the problems raised in the background art.

[0006] As a further aspect of the utility model:

[0007] A main mounting plate of a lidar used for a telescope includes a first fixing frame and a second fixing frame. Both the first fixing frame and the second fixing frame are semi-cylindrical bodies and are arranged in pairs. A semi-circular ring groove is formed in the center of the arc surface of both the first fixing frame and the second fixing frame, and a plurality of fixing grooves are uniformly arranged on one side of the ring groove.

[0008] A slider is slidably connected in the ring groove. The outer end of the slider is fixedly connected with a mounting plate. Semi-circular second clamping plates are rotatably connected to both sides of the mounting plate, and semi-circular first clamping plates are also rotatably connected to both sides of the mounting plate. The first clamping plates are located outside the second clamping plates.

[0009] The outer ends of the first clamping plates are respectively rotatably connected with a first movable plate and a second movable plate on the left and right. The other end of the first movable plate is rotatably connected to the other end of the second movable plate. The length of the first movable plate is less than that of the second movable plate. A force-applying plate is fixedly connected to the connection part of the first movable plate and the second movable plate.

[0010] Furthermore, clamping grooves are formed at both ends of the first fixing frame, and clamping blocks are fixedly connected to both ends of the second fixing frame. The first fixing frame and the second fixing frame are connected to each other by clamping the clamping blocks in the clamping grooves.

[0011] Furthermore, empty grooves are arranged on both the front and rear sides of the first fixing frame at the positions of the clamping grooves. A rotating shaft is vertically and fixedly connected in the empty groove, and a connecting rod is rotatably connected to the rotating shaft. The rotating shaft is fixedly connected to the center of the connecting rod.

[0012] Furthermore, a pressing button and a pushing block are respectively rotatably connected to both ends of the connecting rod. The pressing button vertically penetrates through the side wall of the first fixing frame, and the pushing block vertically penetrates through the partition between the empty groove and the clamping groove.

[0013] Furthermore, springs are fixedly connected to both ends of the connecting rod opposite to the pressing button and the pushing block.

[0014] Furthermore, a convex block for clamping is arranged at the end of the clamping block, and a clamping block is fixedly connected to the inner end of the pushing block. The clamping block is slidably connected to the inside of the clamping groove.

[0015] Furthermore, two protrusions are arranged at the bottom of the slider. The protrusions are both clamped in the annular groove, and the distance between the protrusions is equal to the distance between the three fixing grooves.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] Place the telescope between the first fixing frame and the second fixing frame, align the clamping block and the clamping groove, then press the pressing button, so that the pressing button moves into the empty groove, thereby driving the connecting rod to rotate about the rotating shaft, and further making the pushing block move into the empty groove, so that the clamping block moves towards both ends of the clamping groove, facilitating the insertion of the clamping block into the clamping groove; after the clamping block is placed in the clamping groove, release the pressing button, and the spring expands, so that the pushing block and the pressing button both move towards the outer end of the empty groove, thereby making the pushing block push the clamping block towards the center of the clamping groove, and further clamping the clamping block, so that the telescope is fixed between the first fixing frame and the second fixing frame; place the lidar between the second clamping plates, and pull the force-applying plate towards the direction of the first clamping plate, so that the first movable plate contracts and is placed at the bottom of the second movable plate, thereby making the first clamping plate clamp the second clamping plate, and further completing the fixing of the lidar.
