Description

Technical Field

[0001] The utility model relates to a bracket, in particular to an anti-dumping bracket. Background Art

[0002] Engineering surveying refers to the use of observation instruments and equipment to accurately measure the area to be constructed, record data, and draw diagrams. Generally, the relevant instruments used in engineering surveying need to be installed on a bracket when in use. Due to the different flatness of the ground in different terrains, an anti-dump bracket is required to enable the instrument to be used horizontally.

[0003] The existing anti-dumping bracket can be fixed on uneven ground by inserting a fixing cone into the ground. However, when it is used on a relatively flat ground, it is inconvenient to use and cannot be flexibly changed for use on a flat or uneven ground. Utility Model Content

The mounting plate can be tilted by rotating the circular connecting piece, so that the measuring instrument on the mounting plate can be tilted, and it can be adjusted for use according to the inclination angle of the device installation.

[0010] The two wheels are fixedly secured to the left and right sides of the two guide rails, and the two guide rails are connected with the two guide rails on the left and right sides of the two guide rails respectively.

When reaching a flat ground, the fixed cone can be raised to the height of the bottom plate, so that the lower end of the bottom plate can be in contact with the flat ground for stability.

[0012] In view of this, compared with the prior art, the beneficial effects of the utility model are:

[0013] In the present application, by means of the provided side panels, when used on an uneven ground, the lifting screw rod 2 can be rotated by turning the second knob to make the lifting plate 2 with the fixed cone descend, and the fixed cone can be inserted into the ground for fixation by pressing the pressure block downward; if used on an uneven ground, the second knob can be rotated in the opposite direction to make the lifting screw rod 2 reverse and make the lifting plate 2 with the fixed cone rise, so that the height of the fixed cone is higher than the height of the bottom plate, so that the bottom plate can be stably in contact with the ground for use, and can be flexibly changed for use according to uneven or flat ground.

[0021] Specifically, a lifting screw 3 is rotatably installed between the upper and lower inner walls of the support plate 2, and a sliding rod 4 is fixedly installed. A lifting plate 5 is threadedly installed on the lifting screw 3, and the lifting plate 5 is slidably connected to the sliding rod 4. An opening is provided at the upper end of the support plate 2, and a telescopic plate 6 is fixedly installed at the upper end of the lifting plate 5. By rotating the lifting screw 3, the lifting plate 5 is slid and raised on the sliding rod 4, thereby lifting and lowering the telescopic plate 6, so that the measuring instrument on the mounting plate 12 can be height adjusted.

[0022] Specifically, a rocking wheel 7 is rotatably installed on the right side of the support plate 2, one end of the rocking wheel 7 extends into the support plate 2, and a bevel gear 8 is fixedly installed. The rotating shaft at the lower end of the lifting screw 3 is also fixedly installed with a bevel gear 8. The two bevel gears 8 are meshed with each other. By rotating the rocking wheel 7, the two bevel gears 8 are driven to rotate, thereby driving the lifting screw 3 to rotate for use.

[0023] Specifically, a fixed block 10 is fixedly installed in the middle of the upper end of the connecting plate 9, a circular groove is provided in the upper end of the fixed block 10, a circular connecting piece 11 is rotatably installed in the circular groove, and a mounting plate 12 is fixedly installed on the circular connecting piece 11. By rotating the circular connecting piece 11, the mounting plate 12 can be tilted, so that the measuring instrument on the mounting plate 12 can be tilted, and it can be adjusted for use according to the inclination angle of the device installation.

[0024] Specifically, a bidirectional screw 13 is rotatably installed between the left and right inner walls of the connecting plate 9, and a limiting rod 14 is fixedly installed. A movable plate 15 is threadedly installed on the threads on both sides of the bidirectional screw 13, and the two movable plates 15 are slidably connected to the limiting rod 14. Openings are provided on the left and right sides of the upper end of the connecting plate 9. The two movable plates 15 extend to the upper end of the connecting plate 9 through the openings, and the two movable plates 15 are fixedly installed on the sides close to each other near the upper ends of the two movable plates 15. Through holes are provided on the left and right sides of the fixed block 10, and the two fixing rods 16 are respectively inserted into the two through holes. The two movable plates 15 slide toward each other on the limiting rod 14, thereby carrying the two fixed rods 16 to move toward each other. The circular connecting piece 11 can be rotated and used by moving the two fixed rods 16 away from each other and out of the fixing block 10. However, the two fixed rods 16 can be inserted into the fixing block 10 close to each other and contact the circular connecting piece 11 for limited fixing.

[0025] Specifically, several lifting screws 19 are rotatably installed between the upper and lower inner walls of several side panels 18, and several lifting plates 20 are threadedly installed on several lifting screws 19. An opening is provided on the side of the side panel 18 away from the support plate 2, and the lifting plate 20 extends out of the side panel 18 through the opening. Several upper ends of the side panels 18 are rotatably installed with twists 23, and the twists 23 are fixedly connected to the rotating shafts of the lifting screws 19. Several fixed cones 21 respectively penetrate the several lifting plates 20 longitudinally and are slidably connected thereto, and several upper ends of the fixed cones 21 are fixedly installed with pressing blocks 22. The lifting screws 19 are rotated by twists 23 to make the lifting plate 20 lift and lower with the fixed cones 21. When encountering an uneven ground, the fixed cone 21 is lowered and inserted into the ground for fixing. However, when it reaches a flat ground, the fixed cone 21 is raised to the height of the bottom plate 1, so that the lower end of the bottom plate 1 can be in contact with the flat ground for stability.

[0026] The working principle of the utility model is as follows: the measuring instrument is installed on the mounting plate 12. When it is used on a flat ground, the bottom plate 1 can be directly placed on the ground for use. When it is used on an uneven ground, the plurality of lifting screws 19 are respectively rotated by the plurality of twists 23 to make the plurality of lifting plates 20 with the plurality of fixed cones 21 descend. After the fixed cones 21 descend to a suitable coverage, the fixed cones 21 are pressed downward by the pressing block 22 until they are inserted into the ground for fixing. After the fixing is completed, the two bevel gears 8 can be rotated by rotating the rocker 7, thereby driving the lifting screw 3 to rotate so that the lifting plate 5 slides and rises on the slide rod 4, thereby lifting and lowering the mounting plate 6 with the telescopic plate 6. The measuring instrument on 12 is raised and lowered for height adjustment. If the measuring instrument on the mounting plate 12 is not in a horizontal position, the two-way screw 13 can be rotated by turning the twist 17 to make the two movable plates 15 slide away from each other on the limit rod 14, thereby moving the two fixed rods 16 and leaving the fixed rods 16 in the fixed block 10, and then the circular connecting member 11 can be rotated. By rotating the circular connecting member 11, the mounting plate 12 can be tilted and adjusted. After the measuring instrument on the mounting plate 12 is adjusted to a horizontal position, the twist 17 is rotated in the opposite direction to reverse the two-way screw 13, so that the two fixed rods 16 can be moved closer to each other, inserted into the fixed block 10, and fixed against the circular connecting member 11 to prevent further rotation.
