Description

Technical Field

[0001] The utility model relates to a placing rack, in particular to a placing rack for a geodetic measuring instrument. Background Art

[0002] Geodetic instruments are field surveying instruments used to study the shape, size, position of space objects, gravity field and their changes of the earth. The placement stand for geodetic instruments is a device used to support and fix geodetic instruments. The purpose is to ensure that the geodetic instruments work stably and reliably during the measurement process.

[0003] Since the existing placement rack is generally fixed, it is inconvenient to adjust the height during use. When used on an uneven or soft ground, the placement rack has the defect of poor stability.

[0004] Based on this, it is necessary to design a placement stand for geodetic instruments with good stability and adjustable height. Utility Model Content

The two symmetrical arc-shaped outer walls of the support frame are each provided with a protrusion, and the bidirectional threaded rod is rotatably connected to the protrusion. Two symmetrical arc-shaped clamping plates are commonly screwed on the two bidirectional threaded rods. The arc-shaped clamping plates are in contact and cooperation with the sliding frame. The arc-shaped clamping plates are arranged on both sides of the support frame. The two arc-shaped clamping plates enclose the sliding frame to limit the position on the support frame.

[0007] As a preferred technical solution of the utility model, an anti-slip pad is provided at the bottom of the support seat.

[0008] As a preferred technical solution of the utility model, the telescopic rod is evenly spaced along the circumferential outer wall thereof with limit frames, the limit frames are used to provide limit for the support frame, and the limit frames are arranged below the connecting block.

[0010] As a preferred technical solution of the utility model, a rubber pad is arranged on the inner wall of the arc-shaped clamping plate facing the sliding rack.

[0011] As a preferred technical solution of the utility model, a handle is provided on the outer wall of the telescopic rod.

[0012] As a preferred technical solution of the utility model, a handle is rotatably mounted on the circumferential outer wall of the placement platform.

[0013] Beneficial effect: Through the telescopic function of the telescopic rod, the height of the placement platform can be adjusted, and the height of the geodetic instrument can be flexibly adjusted according to measurement needs.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the protection scope and application scope of the present invention are not limited.

[0022] Embodiment: A stand for a geodetic instrument, such as Figure 1-Figure 6 As shown, it includes a placement platform 1, a connecting block 11, a U-shaped block 3, a cross bar 30, a support frame 2, a sliding frame 21, a telescopic rod 4, a support seat 41 and a limit assembly. The bottom center of the placement platform 1 is connected to the telescopic rod 4. The height of the placement platform 1 is adjusted by extending and contracting the telescopic rod 4. The movable end of the telescopic rod 4 is connected to the support seat 41. The support seat 41 contacts the placement plane as a base. The bottom of the support seat 41 is provided with an anti-skid pad 42. The anti-skid pad 42 is provided to increase the friction between the support seat 41 and the placement plane, thereby improving the stability of the placement platform 1. The bottom of the placement platform 1 is evenly spaced along its circumference. There are three connecting blocks 11. The number of connecting blocks 11 can be appropriately increased according to usage and design requirements. A cross bar 30 is rotatably connected to the connecting block 11, and a U-shaped block 3 is connected to the cross bar 30. The bottom of the U-shaped block 3 is connected to a support frame 2. One end of the cross bar 30 that passes through the U-shaped block 3 is screwed with a threaded sleeve 31. When the threaded sleeve 31 is tightened, the threaded sleeve 31 abuts against the support frame 2, thereby limiting the support frame 2. A sliding frame 21 is slidably connected to the support frame 2. The bottom end of the sliding frame 21 is conical, which is convenient for insertion into soft soil layers, indicating the stability of the placement platform 1. A limiting component for limiting the sliding frame 21 is provided on the support frame 2.

[0023] like Figure 3-Figure 6 As shown, the limiting assembly includes a protrusion 22, an arc-shaped clamping plate 5 and a bidirectional threaded rod 6. The two symmetrical arc-shaped outer walls of the support frame 2 are each provided with a protrusion 22, and the bidirectional threaded rod 6 is rotatably connected to the protrusion 22. Two symmetrical arc-shaped clamping plates 5 are screwed together on the two bidirectional threaded rods 6. The two arc-shaped clamping plates 5 are symmetrically arranged on both sides of the support frame 2 with the support frame 2 as the center. The arc-shaped clamping plates 5 are in contact and cooperate with the sliding frame 21. A rubber pad 51 is arranged on the inner wall of the arc-shaped clamping plate 5 facing the sliding frame 21. The rubber pad 51 is arranged to increase the friction between the arc-shaped clamping plate 5 and the sliding frame 21. At the same time, it can also prevent the sliding frame 21 from being damaged due to the rigid contact between the arc-shaped clamping plate 5 and the sliding frame 21. The two arc-shaped clamping plates 5 surround the sliding frame 21 and limit it on the support frame 2.

[0024] like Figure 5 As shown, the telescopic rod 4 is evenly spaced along its circumferential outer wall with limit frames 43 , which are used to provide support and limit for the support frame 2 when it is folded, and the limit frames 43 are arranged below the connecting block 11 .

[0025] like Figure 1 As shown, a handle 7 is provided on the outer wall of the telescopic rod 4, and a carrying handle 8 is rotatably installed on the circumferential outer wall of the placement platform 1. The arrangement of the handle 7 and the carrying handle 8 facilitates the placement rack to be carried portablely.

[0026] When in use, the height of the placement platform 1 is adjusted by extending the telescopic rod 4, so that the height position of the measuring instrument can be flexibly adjusted according to the measurement needs; in order to improve the stability of the placement platform 1, the U-shaped block 3 is rotated along the cross bar 30 by a certain angle, so that a certain angle is formed between the support frame 2 and the telescopic rod 4, forming a triangular structure, thereby improving the stability of the placement platform 1; after the U-shaped block 3 is rotated to a suitable angle, the U-shaped block 3 is fixed by the threaded sleeve 31 and the threaded end of the cross bar 30, thereby keeping the support frame 2 stable; the sliding frame 21 extends along the plane of the support frame 2, and the distance between the two arc-shaped clamping plates 5 is adjusted by the bidirectional threaded rod 6, so that the arc-shaped clamping plates 5 effectively fix the sliding frame 21 on the support frame 2, thereby The relative extension movement of the support frame 2 is realized to meet the stability requirement of the placement platform 1; when the device needs to be folded, the distance between the two arc-shaped clamping plates 5 is expanded by unscrewing the bidirectional threaded rod 6. After the sliding frame 21 moves up to the highest point along the support frame 2, the bidirectional threaded rod 6 is tightened again to fix the sliding frame 21 on the support frame 2, and then the U-shaped block 3 is rotated and reset, and the support frame 2 is provided with support and fixing by the limit frame 43. Then, the support seat 41 is moved up and reset by contracting the telescopic rod 4, so that the bottom end of the sliding frame 21 is inserted into the corresponding socket of the support seat 41. In this way, the folding of the placement rack is realized. After folding, the volume is small and the placement rack can be conveniently lifted away by the handle 7 or the handle 8, so that the placement rack can be carried portablely.

[0027] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
