Description
Technical Field
[0001] The utility model relates to the field of surveying and mapping, in particular to a light-shielding bracket for a surveying and mapping level. Background Art
[0002] In the field of surveying and mapping, a level is generally used to measure the height difference between two points on the ground. The level is mostly used outdoors. When the sun is strong, measuring the height difference between two points with a level will produce glare, which will not only make the surveyor feel uncomfortable, but also affect the reading of the measurement results. In order to facilitate adjustment, the level mounted on the tripod needs to have multiple adjustment knobs on the outer shell. The outer shells of various types of level are distributed differently, and it is difficult to install a universal shading bracket to achieve shading. Utility Model Content
[0003] The purpose of the utility model is to provide a light shielding bracket for a surveying and mapping level instrument to solve the above technical problems.
[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a surveying and mapping level light-shielding bracket, comprising a counterweight top cover, a mounting groove, a universal mounting bracket, a cushion, a level clamping position, a hinge, and a light-shielding plate. A mounting groove is opened at the front of the top end of the counterweight top cover, the universal mounting bracket is installed in the mounting groove, the level clamping position is arranged between the counterweight top cover and the universal mounting bracket, the cushion is fixed to the bottom end of the counterweight top cover, the hinge is installed at the front end of the counterweight top cover, and the light-shielding plate is hinged to the counterweight top cover through the hinge resistance.
[0005] On the basis of the above technical scheme, the universal mounting bracket includes a box body, an airbag groove, a clamping airbag, a connecting pipe, a connecting port, a hose, a hand-squeezed airbag, and an air release valve. The two box bodies are respectively fixed to the left and right parts of the bottom end of the counterweight top cover. The airbag grooves are respectively opened at the inner ends of the box bodies. The clamping airbag is installed on the box body through the airbag grooves. The connecting pipe connects the two clamping airbags through the top end of the box body, and the connecting pipe is installed in the mounting groove. The connecting port is opened at the left end of the left box body. The right end of the hose is connected to the airbag through the connecting port. The hand-squeezed airbag is installed at the left end of the hose, and the air release valve is installed on the left part of the hose.
[0006] On the basis of the above technical solution, the hand-pinch inflatable bag is clamped on the level by inflating the clamped airbag with air through a hose so that the airbag groove is clamped.
[0007] Compared with the prior art, the utility model has the following advantages: the utility model uses a counterweight top cover to be placed on the top of the level without a knob, and uses a universal mounting bracket controlled by a hand-pinch airbag to clamp the level, so that the shading plate can be set, thereby realizing the installation of the shading bracket without paying attention to the distribution adjustment knobs of the level shell.

DETAILED DESCRIPTION
[0012] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0013] like Figures 1 to 3 As shown, a surveying and mapping level shading bracket includes a counterweight top cover 1, a mounting groove 2, a universal mounting bracket 3, a cushion 4, a level clamping position 5, a hinge 6, and a shading plate 7. The counterweight top cover 1 has a mounting groove 2 at the front of the top, the universal mounting bracket 3 is installed in the mounting groove 2, the cushion 4 is fixed to the bottom of the counterweight top cover 1, the level clamping position 5 is arranged between the counterweight top cover 1 and the universal mounting bracket 3, the hinge 6 is installed at the front end of the counterweight top cover 1, and the shading plate 7 is hinged to the counterweight top cover 1 through the resistance of the hinge 6.
[0014] The universal mounting bracket 3 includes a box body 8, an airbag groove 9, a clamping airbag 10, a connecting pipe 11, a connecting port 12, a hose 13, a hand-pinch airbag 14, and an air release valve 15. The two box bodies 8 are respectively fixed to the left and right parts of the bottom end of the counterweight top cover 1. The airbag grooves 9 are respectively opened at the inner ends of the box bodies 8. The clamping airbag 10 is installed on the box body 8 through the airbag grooves 9. The connecting pipe 11 connects the two clamping airbags 10 through the top end of the box body 8, and the connecting pipe 11 is installed in the mounting groove 2. The connecting port 12 is opened at the left end of the left box body 8. The right end of the hose 13 is connected to the airbag 10 through the connecting port 12. The hand-pinch airbag 14 is installed at the left end of the hose 13, and the air release valve 15 is installed on the left part of the hose 13.
[0015] The hand-pinch inflatable bag 14 inflates the clamping air bag 10 through the rubber hose 13 to inflate the air bag groove 9 and clamp it on the level.
[0016] The working principle of the utility model is as follows: when in use, the counterweight cover 1 is placed on the top of the level through the cushion 4 to stabilize it, so that the left and right boxes 8 are placed on the left and right sides of the level, and the airbag 14 is inflated by hand, and the rubber hose 13 is inflated to the left clamping airbag 10 through the connecting port 12, and the left and right clamping airbags 10 are inflated synchronously through the connecting pipe 11 to bulge the airbag groove 9 to clamp and stabilize the level. The shading plate 7 is flipped through the hinge 6 to shade the lens of the level. The shading bracket installation is realized without ignoring the distribution adjustment knob of the level shell.
[0017] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
