Description

Technical Field

[0001] This utility model relates to the field of support device technology, and in particular to a theodolite measuring support. Background Art

[0002] A measuring stand is a tool used to fix and support measuring equipment. Its main purpose is to provide a stable working platform to ensure the accuracy of measurements. Measuring stands are commonly used to accurately measure the dimensions, angles, or shapes of objects, ensuring the reliability of the measurement results.

[0003] The existing support is a tripod. When in use, the tripod is unfolded and supported by the pointed end at the bottom, which is also convenient to insert into the soil for fixation. However, this type of tripod has a high center of gravity. When used on a concrete ground, the bottom of the pointed end has a small contact area. In addition, due to the high center of gravity of the equipment, the entire support is prone to tilting and falling due to collisions, which can damage the theodolite. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a theodolite measuring bracket.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A theodolite measuring bracket includes a base, an operating cylinder fixedly connected to the upper surface of the base, a support column fixedly connected to the upper surface of the operating cylinder, a mounting base fixedly connected to the top of the support column, and an adjustment and positioning mechanism rotatably connected to the inner wall of the operating cylinder.

[0007] The adjustment and positioning mechanism includes a worm gear rotatably connected to the inner wall of the operating cylinder. One end of the worm gear passes through the surface of the operating cylinder and is fixedly connected to a knob. A through hole is provided on the lower surface of the base. A rotating shaft is rotatably connected to the inner top wall of the operating cylinder. A turbine is fixedly connected to the surface of the rotating shaft. The worm gear meshes with the turbine. A gear is fixedly connected to the surface of the rotating shaft. The gear is installed inside the through hole.

[0008] The inner wall of the base is slidably connected with a first counterweight rack, a second counterweight rack, a third counterweight rack, and a fourth counterweight rack. The first counterweight rack meshes with a gear, the second counterweight rack meshes with a gear, the third counterweight rack meshes with a gear, and the fourth counterweight rack meshes with a gear.

[0009] Preferably, the inner wall of the first counterweight rack is threaded with a first screw, the inner wall of the second counterweight rack is threaded with a second screw, the inner wall of the third counterweight rack is threaded with a third screw, and the inner wall of the fourth counterweight rack is threaded with a fourth screw.

[0010] Preferably, the lengths of the first screw, second screw, third screw, and fourth screw gradually decrease.

[0011] Preferably, the surface of the base is provided with multiple clearance holes.

[0012] Preferably, a U-shaped plate is fixedly connected to the surface of the support column, and a folding sunshade is installed on the inner wall of the U-shaped plate.

[0013] Preferably, the support column is in the shape of a hollow cone.

[0014] The beneficial effects of the utility model are:

[0015] 1. The rotation of the turbine drives the rotation of the rotating shaft, which in turn drives the gear to rotate. The gear then causes the first, second, third, and fourth counterweight racks to slide out of the base. The first, second, third, and fourth counterweight racks move away from each other, lowering the overall center of gravity of the support column and better preventing it from tipping over due to impact during use.

[0016] 2. When it is necessary to store the first, second, third, and fourth counterweight racks, simply reverse the knob to save space. By operating the first, second, third, and fourth screws, they will be lowered and driven into the soil for fixation. Attached Figure Description

[0024] The adjustment and positioning mechanism includes a worm gear 10 rotatably connected to the inner wall of the operating cylinder 2. One end of the worm gear 10 passes through the surface of the operating cylinder 2 and is fixedly connected to a knob 7. A through hole 20 is opened on the lower surface of the base 1. A rotating shaft 8 is rotatably connected to the inner top wall of the operating cylinder 2. A turbine 9 is fixedly connected to the surface of the rotating shaft 8. The worm gear 10 meshes with the turbine 9. A gear 11 is fixedly connected to the surface of the rotating shaft 8. The gear 11 is installed inside the through hole 20.

[0025] The inner wall of the base 1 is slidably connected with a first counterweight rack 12, a second counterweight rack 15, a third counterweight rack 16, and a fourth counterweight rack 17. The first counterweight rack 12 meshes with the gear 11, the second counterweight rack 15 meshes with the gear 11, the third counterweight rack 16 meshes with the gear 11, and the fourth counterweight rack 17 meshes with the gear 11.

[0026] In this invention, a mounting base 4 is provided for mounting the theodolite equipment, a base 1 is provided for overall bottom support, a knob 7 is provided for the operator to rotate, causing the worm gear 10 to rotate, which in turn causes the turbine 9 to rotate, a rotating shaft 8 is provided for mounting the turbine 9 and the gear 11, a through hole 20 is provided to allow space for the installation of the gear 11, and a first counterweight rack 12, a second counterweight rack 15, a third counterweight rack 16 and a fourth counterweight rack 17 are provided, so that the rotation of the gear 11 simultaneously drives the first counterweight rack 12, the second counterweight rack 15, the third counterweight rack 16 and the fourth counterweight rack 17 to slide, and when not in use, the first counterweight rack 12, the second counterweight rack 15, the third counterweight rack 16 and the fourth counterweight rack 17 are stored in the base 1 to save space.

[0027] The inner wall of the first counterweight rack 12 is threaded with a first screw 14, the inner wall of the second counterweight rack 15 is threaded with a second screw 13, the inner wall of the third counterweight rack 16 is threaded with a third screw 18, and the inner wall of the fourth counterweight rack 17 is threaded with a fourth screw 19.

[0028] In this invention, by providing a first screw 14, a second screw 13, a third screw 18, and a fourth screw 19, the height of the screw can be adjusted by rotation during use, allowing it to be driven into softer soil for fixation.

[0029] The lengths of the first screw 14, the second screw 13, the third screw 18, and the fourth screw 19 gradually decrease.

[0030] In this invention, by setting the lengths of the first screw 14, the second screw 13, the third screw 18, and the fourth screw 19 to gradually decrease, multiple screws of different heights can be driven into the soil after rotation.

[0031] The surface of the base 1 has multiple clearance holes 21.

[0035] The support column 3 is hollow cone in shape.

[0036] In this invention, by setting the shape of the support column 3 as a hollow cone, the overall center of gravity of the equipment is lowered, which better prevents the support column 3 from tipping over due to collision during use.

[0037] Working principle: In use, the operator rotates knob 7, which drives worm gear 10 to rotate. Worm gear 10 drives turbine gear 9 to rotate, which in turn drives rotating shaft 8 to rotate. Rotating shaft 8 drives gear 11 to rotate, which in turn drives first counterweight rack 12, second counterweight rack 15, third counterweight rack 16, and fourth counterweight rack 17 to slide out from base 1. The first counterweight rack 12, second counterweight rack 15, third counterweight rack 16, and fourth counterweight rack 17 move away from each other, lowering the overall center of gravity of support column 3. When it is necessary to move the base... 1. When fixing, rotate the first screw 14, the second screw 13, the third screw 18 and the fourth screw 19 to lower them and drive them into the soil for fixation. When the theodolite mounted on the mounting base 4 is working, the folding sunshade 6 can be opened for sunshade operation. When it is necessary to store the first counterweight rack 12, the second counterweight rack 15, the third counterweight rack 16 and the fourth counterweight rack 17, simply reverse the knob 7. The support column 3 is hollow cone in shape, with a light structure and a lower center of gravity of the equipment. With the above structure, the support column 3 is better prevented from tipping over due to collision during use.
