[0025] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figures 1 to 3 The details of the embodiments will be clearly presented. The contents mentioned in the following embodiments are all based on the drawings in the specification.

[0026] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0027] Embodiment 1, the utility model is a high-altitude positioning bracket for measuring instruments. The high altitude in this application is not a suspended high altitude, but a higher position on each floor of a building. It is mainly used to install air ducts or fire pipes, etc., and to place, for example, an infrared laser measuring instrument for high-altitude elevation and flatness testing. It includes a vertical support tube 1, the upper end of the support tube 1 is a cavity, and a telescopic tube 3 is installed in the support tube 1 to slide up and down. A threaded adjustment hole is opened at the upper end of the support tube 1, and a threaded adjustment rod 8 is rotatably installed at the adjustment hole. The adjustment rod 8 can be adjusted in the adjustment hole. The bracket is installed on the telescopic tube 3 so as to slide up and down, and the bracket includes a sleeve 4 which slides on the telescopic tube 3. The sleeve 4 is provided with a fixing hole with a thread. A fixing rod 7 with a thread is installed at the fixing hole. The fixing rod 7 can be rotated and inserted at the fixing hole to press against the telescopic tube 3 to ensure that the bracket is fixed. Support plates 5 are fixed on both sides of the sleeve 4. The support plates 5 are used to place the infrared laser measuring instrument. Lower baffles 6 are fixed on both sides of the support plate 5, which will not affect the emission of the infrared laser measuring instrument, but can prevent the infrared laser measuring instrument from falling.

[0028] Working principle:

[0029] Adjust the position of the bracket on the telescopic tube 3, tighten the fixing rod 7 to fix it, place the infrared laser measuring instrument on the bracket, adjust the position of the telescopic tube 3 in the support tube 1, tighten the adjusting rod 8 to fix it, and you can also place the infrared laser measuring instrument at this time, stabilize the base 2 to ensure the overall stability, the telescopic tube 3 can be used for long-distance height adjustment, and the sleeve 4 can be used for short-distance adjustment.

[0030] Embodiment 2, the utility model is a high-altitude positioning bracket for a measuring instrument, comprising a vertical supporting tube 1, at the lower end of which a triangular stabilizing support 2 is fixed, and for the convenience of movement, a universal wheel 14 is installed below the stabilizing support 2, which can be moved quickly and needs to be fixed after being moved to a suitable position. One way is to use a universal wheel 14 with a brake, but each wheel needs to be replaced with a brake universal wheel 14, and another way is that the lower interior of the supporting tube 1 is a cavity, and a "]"-shaped sliding hole 15 is opened on its side wall, and a stabilizing rod 16 that slides and rotates in the supporting tube 1 is arranged in the sliding hole 15, and a limiting column 17 that slides in the sliding hole 15 is fixed on the stabilizing rod 16, and a friction plate 18 is fixed to the lower end of the stabilizing rod 16.

[0031] When fixation is required, the limiting column 17 is first moved from the horizontal hole at the upper end of the sliding hole 15 to the vertical hole, and then slides downward to move the stabilizing rod 16 downward. When the friction plate 18 contacts the ground, the limiting column 17 moves to the lower end of the sliding hole 15 and then moves to the left for limiting, so that the friction plate 18 is fixed to the ground by friction. The operation is simple and the cost is low.

[0032] The upper end of the support tube 1 is a cavity, and a limit bolt 9 is fixed on its upper end. An adjusting bolt 10 is also rotatably installed at the upper end of the support tube 1. The outer diameter of the adjusting bolt 10 is larger than that of the support tube 1. It is placed on the outside of the support tube 1 and is provided with an anti-slip groove 13. The inner threads of the limit bolt 10 and the adjusting bolt 10 match the telescopic tube 2 placed in the support tube 1. The outside of the telescopic tube 2 is provided with an external thread. When the adjusting bolt 10 is rotated, the telescopic tube 3 will move up and down under the action of the adjusting bolt 10 and the limit bolt 9, and will not fall due to its own weight under the action of the thread. A bracket is installed on the telescopic tube 3 to slide up and down. The bracket includes a sleeve 4 that slides up and down. Support plates 5 are fixed on both sides of the sleeve to prevent the infrared laser measuring instrument from falling. Baffles 6 are fixed on both sides of the support plate 5. A threaded fixing hole is opened on the sleeve 4, and a fixing rod 7 is installed on the inner thread of the fixing hole.

[0033] The fixing rod 7 is rotated, and the fixing rod 7 squeezes the telescopic tube 3 to fix the bracket on the telescopic tube 3. The infrared laser measuring instrument is placed on the support plate 5. The baffle 6 on the support plate 5 will not block the infrared laser measuring instrument. The telescopic tube 3 is adjusted by rotating the adjusting bolt 10 for convenient operation, and the telescopic tube 3 will not slide down due to its own weight.

[0034] In order to realize the rotation of the adjusting bolt 10, a rotating ring 12 is fixed to the upper and lower ends of the adjusting bolt 10, and a rotating groove 11 matching the rotating ring 12 is opened on the support tube 1, so that the adjusting bolt 10 is rotatably connected to the support tube 1, thereby driving the telescopic tube 3 to move up and down.

[0035] Working principle:

[0036] Place the stable base 2 at a suitable position, fix it to the ground via the universal wheel 14 with brakes or the stabilizing rod 16, adjust the position of the support plate 5 on the telescopic tube 3, place the infrared laser measuring instrument, turn the adjusting bolt 10, and move the telescopic tube 3 upward to a suitable position. You can also place the infrared laser measuring instrument at this time to test the high altitude elevation and flatness of the air duct or fire protection pipe.

[0037] The utility model has the following technical effects.

[0038] 1. The utility model can play a good role in fixing and supporting by stabilizing the base. The measuring height of the infrared laser measuring instrument can be adjusted by sliding the telescopic tube up and down in the supporting tube.
