Description

Technical Field

[0001] This utility model relates to the field of leveling technology, specifically to a leveling device that is easy to quickly correct. Background Technology

[0002] In construction engineering, topographic surveying, equipment installation and other occasions, optical measuring instruments such as levels and total stations must be kept strictly level to ensure reading accuracy. The traditional method is to use three-legged screws on a tripod to repeatedly "coarsely level" and "finely level" to complete the leveling, which is a cumbersome and time-consuming process.

[0003] Therefore, the market urgently needs a rapid calibration device that can be quickly integrated with conventional support frames and can keep the measuring instrument in a horizontal position without repeated adjustments to the support frame.

[0004] Based on this, a leveling measurement device that is easy to quickly correct is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] To address the aforementioned issues, a leveling device that facilitates rapid calibration is provided, which solves the problem of inconvenient adjustment of the tripod by using a universal joint and an adjustment mechanism.

[0006] To address the problems of existing technologies, this utility model provides a leveling measuring device that facilitates rapid calibration, including a support frame, a support plate on the support frame, an adjustment plate above the support plate, a measuring instrument detachably mounted on the adjustment plate, and the adjustment plate and the support plate connected by a lifting mechanism and a universal mechanism. The lifting mechanism is further provided with an adjustment mechanism for adjusting the height to achieve angle adjustment.

[0007] Preferably, the lifting mechanism includes a limiting slide plate, a sliding block, a sliding shaft, and a sliding groove. The supporting plate is symmetrically provided with limiting slide plates, and a sliding block is slidably provided between the limiting slide plates. A sliding shaft is provided on the sliding block, and a sliding groove is provided on each of the limiting slide plates for the two ends of the sliding shaft to slide. A universal mechanism is provided above the sliding block to connect with the bottom wall of the adjusting plate.

[0008] Preferably, the universal mechanism includes a sleeve, a universal ball, a connecting rod, and a support column. The sleeve is arranged in an equilateral triangle on the bottom wall of the adjusting plate. The universal ball is rotatably mounted inside the sleeve. A support column is provided on the bottom wall of any one of the universal balls. The support column is connected to the bottom wall of the support plate. The other two universal balls are provided with connecting rods on their bottom walls. The other end of the connecting rod is connected to the top wall of the sliding block.

[0009] Preferably, the adjusting mechanism includes a fixed block, an adjusting block, and a lead screw. The adjusting block is disposed on the side wall of the sliding block, the fixed block is disposed on the side wall of the limiting slide plate, one end of the lead screw passes through the adjusting block and rotates with the inner wall of the fixed block, and the adjusting block is provided with a thread that engages with the lead screw.

[0010] Preferably, the other end of the lead screw is provided with a rotary knob.

[0011] The advantages of this utility model compared to the prior art are:

[0012] This invention utilizes a three-point universal ball joint and differential lifting principle, allowing for fine-tuning of the horizontal position by simply rotating any knob while keeping the support frame stationary. This eliminates the hassle of repeatedly moving the support frame, significantly shortens the setup time, and improves work efficiency. Attached Figure Description

Detailed Implementation

[0017] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0018] Reference Figures 1-3A leveling measuring device that facilitates rapid calibration includes a support frame 101, a support plate 102 on the support frame 101, an adjusting plate 103 above the support plate 102, a measuring instrument 104 detachably mounted on the adjusting plate 103, and the adjusting plate 103 and the support plate 102 connected by a lifting mechanism 200 and a universal mechanism 300. The lifting mechanism 200 is also provided with an adjusting mechanism 400 for adjusting the height to achieve angle adjustment.

[0019] The lifting mechanism 200 and the universal mechanism 300 are used in conjunction with the adjustment mechanism 400 to adjust the measuring instrument 104 to a horizontal position, eliminating the need to use an adjustment bracket to keep the measuring instrument 104 horizontal, thus facilitating operation.

[0020] Reference Figures 2-3 The lifting mechanism 200 includes a limiting slide plate 201, a sliding block 202, a sliding shaft 203, and a sliding groove 204. The limiting slide plates 201 are symmetrically arranged on the support plate 102. The sliding blocks 202 are slidably arranged between the limiting slide plates 201. The sliding shaft 203 is provided on the sliding block 202. The limiting slide plates 201 are all provided with sliding grooves 204 for sliding at both ends of the sliding shaft 203. A universal mechanism 300 is provided above the sliding block 202 and connected to the bottom wall of the adjusting plate 103.

[0021] The sliding block 202 slides within the sliding groove 204 via the sliding shaft 203, enabling it to move up and down within the limiting slide plate 201.

[0022] Reference Figures 2-3 The universal mechanism 300 includes a sleeve 301, universal balls 302, connecting rods 303, and support columns 304. The sleeves 301 are arranged in an equilateral triangle on the bottom wall of the adjusting plate 103. Universal balls 302 are rotatably arranged inside the sleeves 301. A support column 304 is provided on the bottom wall of any one of the universal balls 302. The support column 304 is connected to the bottom wall of the support plate 102. The other two universal balls 302 are provided with connecting rods 303 on their bottom walls. The other end of the connecting rod 303 is connected to the top wall of the sliding block 202.

[0023] The sliding block 202 can move up and down to drive the connecting rod 303 to move. When a single connecting rod 303 moves up and down, the angle of tilt of the adjusting plate 103 in different directions can be adjusted by the cooperation of the sleeve 301 and the universal ball 302.

[0024] Reference Figures 2-3The adjusting mechanism 400 includes a fixed block 402, an adjusting block 403, and a lead screw 404. The adjusting block 403 is disposed on the side wall of the sliding block 202, and the fixed block 402 is disposed on the side wall of the limiting slide plate 201. One end of the lead screw 404 passes through the adjusting block 403 and rotates with the inner wall of the fixed block 402. The adjusting block 403 is provided with a thread that mates with the lead screw 404.

[0025] Rotating the knob 401 can drive the lead screw 404 to rotate. Through the cooperation of the lead screw 404 and the adjusting block 403, the adjusting block 403 can slide up and down on the lead screw 404. The adjusting block 403 can drive the sliding block 202 to slide up and down.

[0026] Reference Figures 2-3 The other end of the lead screw 404 is provided with a rotary knob 401.

[0027] Working principle: Rotating the knob 401 drives the lead screw 404 to rotate. Through the cooperation of the lead screw 404 and the adjusting block 403, the adjusting block 403 can slide up and down on the lead screw 404. The adjusting block 403 can drive the sliding block 202 to slide up and down. The sliding block 202 slides in the sliding groove 204 through the sliding shaft 203, and can move up and down in the limiting slide plate 201. The up and down movement of the sliding block 202 can drive the connecting rod 303 to move. When a single connecting rod 303 moves up and down, the angle of tilt of the adjusting plate 103 in different directions can be adjusted through the cooperation of the sleeve 301 and the universal ball 302. This allows the measuring instrument 104 to be adjusted to a horizontal position, eliminating the need to use an adjusting bracket to keep the measuring instrument 104 in a horizontal state, thus facilitating operation.
