Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping equipment, in particular to a stable supporting device for a rangefinder. Background Art

[0002] Laser rangefinder is an instrument that uses a certain parameter of modulated laser to measure the distance to the target. It is widely used in the field of surveying and mapping, such as topographic surveying, road surveying, hydrological surveying, mining surveying and construction surveying. Laser rangefinder is divided into phase rangefinder and pulse rangefinder according to the distance measurement method. Laser rangefinder is light in weight, small in size, simple to operate, fast and accurate, and its error is only one-fifth to several hundredths of other optical rangefinders. Existing laser rangefinders are usually handheld or supported by their brackets when in use, but the existing methods can only play a supporting role during surveying and mapping. In some places with complex terrain, the bracket cannot be adjusted according to the terrain, and the bracket will appear in a suspended state. The measuring instrument is prone to jitter during use, resulting in inaccurate data and other problems. In addition, the angle cannot be fixed when adjusting the angle. The angle is easily deflected when accidentally touched, and the angle needs to be adjusted twice or multiple times, resulting in a waste of time. Utility Model Content

At the same time, the corresponding lifting rod 5 is driven to move through the connecting rod 6. After the stable placement is completed, the support is fixed by the damping sleeve rod 3, the damping plug rod 4 and the compression spring 27. After the base 28 on the rod 2 is in stable contact with the ground, the locking device 7 is used to fix the angle of the support rod 2, so that it can be stably placed on the ground to avoid shaking caused by unstable placement. At the same time, when it is not locked, the damping rod 4 and the damping sleeve rod 3 can be used to reduce the arc of the shaking of the bracket 1 caused by collision, avoid excessive shaking, and improve stability 1. An adjustment frame 8 is provided to facilitate adjustment of the angle of the rangefinder body 10, and a mounting frame 9 is provided to facilitate installation and fixing of the rangefinder body 10. A damping device is provided at the connection between the adjustment frame 8 and the mounting frame 9 to facilitate angle adjustment.

[0024] The locking device 7 includes a swivel 11 and a clamping block 12 corresponding to the lifting rod 5 one by one. The outer wall of the lifting rod 5 is provided with a plurality of clamping grooves 13 evenly distributed along its circumferential direction. The clamping block 12 can be inserted into the clamping groove 13 on its corresponding side. The clamping block 12 is slidably connected to the bracket 1. The side of the clamping block 12 away from the axis of the bracket 1 is an arc surface. A sliding groove 14 is provided on the outer wall of the clamping block 12.

The outer wall of the clamping groove 13 is arranged to be arc-shaped and a sliding groove 14 is opened on the arc-shaped side. A sliding block 15 is arranged in the sliding groove 14. The swivel 11 can be used to rotate to drive the sliding block 15 to slide in the sliding groove 14, and then the swivel 11 can be used to drive the clamping block 12 to move. The clearance groove 16 is provided to provide space for the movement of the clamping block 12.

[0026] The adjusting frame 8 includes a rotating shell 17, an adjusting rod 18 is fixedly connected to the outer wall of the rotating shell 17, a rotating rod 19 is coaxially rotatably connected inside the adjusting rod 18, a bevel gear 20 located in the rotating shell 17 is fixedly connected to the right end of the rotating rod 19, a bevel gear 21 meshing with the bevel gear 20 and coaxial with the bracket 1 is provided in the rotating shell 17, the bevel gear 21 is fixedly connected to the bracket 1, a limiting rod 22 is coaxially rotatably connected inside the adjusting rod 18, the limiting rod 22 is rotatably connected to a limiting tooth block 23 located in the rotating shell 17 at the left end, a spur gear 24 meshing with the limiting tooth block 23 and coaxial with the bracket 1 is provided in the rotating shell 17, and the spur gear 24 is fixedly connected to the bracket 1.

[0027] like Figures 1 to 7 As shown, a rotating shell 17 is provided to facilitate rotational connection, an adjusting rod 18, a rotating rod 19, a bevel gear 20, and a bevel toothed disc 21 are provided, and the adjusting rod 18 can be used to adjust the angle. At the same time, the rotating rod 19 can be used to rotate and drive the bevel gear 20 to rotate on the bevel toothed disc 21, so as to achieve the purpose of fine-tuning and make the adjustment angle more accurate. A limiting rod 22, a limiting tooth block 23 and a spur gear 24 are provided, and the limiting rod 22 can be used to change the position of the limiting tooth block 23 to achieve the purpose of meshing or disengaging with the spur gear 24, so as to achieve the purpose of facilitating angle adjustment and fixing the adjustment angle, and avoiding the problem of angle change due to collision and the need for secondary adjustment.

[0028] A U-shaped limiting groove 25 is provided at the lower side of the adjusting rod 18 , and the right side of the limiting rod 22 is located in the limiting groove 25 .

[0029] like Figure 5 As shown, the limiting groove 25 is arranged in a U shape and the left end of the limiting rod 22 is located in the limiting groove 25. The limiting groove 25 can be used to fix the position of the limiting rod 22 for easy operation.

[0030] The upper side of the bracket 1 is rotatably connected with a sleeve ring 26 located inside the rotating shell 17 , and the lower end of the sleeve ring 26 is slidably connected to the upper end of the limiting tooth block 23 .

[0031] like Figure 3 and Figure 6 As shown, a rotatable collar 26 is provided to limit the limit tooth block 23, thereby preventing the limit tooth block 23 from rotating due to the rotation of the limit rod 22 and making it lose its function, thereby ensuring that the limit tooth block 23 can mesh with the spur gear 24 at any time.

[0032] A compression spring 27 located between the damping sleeve rod 3 and the damping insert rod 4 is fixedly connected inside the damping sleeve rod 3 .

[0033] like Figure 3 As shown, the compression spring 27 can be used to support the bracket 1, so as to facilitate the resetting and angle adjustment of the damping sleeve rod 3 and the damping insertion rod 4.

[0034] The support rod 2 is hingedly connected to a base 28 at its lower end, and a non-slip rubber plate is fixedly connected to the lower end of the base 28 .

[0035] like Figure 1 As shown, providing a rotatable base 28 can ensure that the base 28 can contact the ground, avoiding it from being suspended in the air due to angle problems, causing the bracket 1 to be placed unstable. Providing an anti-slip rubber plate is convenient for protecting the base 28 while increasing the friction with the ground, thereby improving the stability of the bracket 1.

[0036] When the utility model is used, when placed on a flat ground, the bracket 1 can be directly placed on the ground, the base 28 is in contact with the ground for support, and then the swivel 11 is rotated to lock the position of the lifting rod 5, and the placement can be completed;

[0037] When placed on an uneven ground, the bracket 1 can be pressed down vertically. After the support rod 2 contacts the ground at different heights, the angle changes, the damping sleeve rod 3 and the damping plug rod 4 contract, the compression spring 27 is compressed, and the damping plug rod 4 drives the lifting rod 5 to move via the connecting rod 6. When all the support rods 2 contact the ground, the swivel 11 is rotated, and the swivel 11 drives the clamping block 12 to move toward the direction of the lifting rod 5 on its corresponding side through the sliding block 15, until the clamping block 12 enters the clamping groove 13 on its corresponding side to fix the position of the lifting rod 5, and then the swivel 11 is released to complete the placement of the bracket 1;

[0038] During measurement, when angle adjustment is required, first, the limit rod 22 is moved along the limit groove 25 to the U-shaped vertical groove on the left side of the limit groove 25, and the limit tooth block 23 is released from the meshing with the spur gear 24. Then, the adjusting rod 18 can be used to drive the rotating shell 17 to rotate, thereby driving the rangefinder body 10 to adjust the angle. At the same time, the bevel gear 20 is meshed with the bevel gear disk 21, causing the bevel gear 20 to drive the rotating rod 19 to rotate. After the rough adjustment of the angle is completed, the bevel gear 20 can be driven to rotate by rotating the rotating rod 19, and then the rotating shell 17 can be driven by the bevel gear disk 21 to perform fine angle adjustment to make the angle more accurate. After the adjustment is completed, the limit rod 22 is moved to the right to return to its original position, thereby driving the limit tooth block 23 to mesh with the spur gear 24 again, completing the fixation of the rotating shell 17, and then completing the angle fixation to avoid angle changes caused by collision.
