[0002] A total station, also known as a total station electronic distance meter, is a high-tech measuring instrument that integrates optics, mechanics, and electronics. It is a surveying and mapping instrument system that integrates horizontal angle, vertical angle, distance (slant distance, horizontal distance), and height difference measurement functions. The prism assembly on existing total stations is generally installed in an integrated manner, which is difficult to disassemble separately. As a result, the entire total station will be scrapped if the prism assembly is damaged, which increases the cost of use. Utility Model Content

[0012] 1. The miniature tubular total station prism assembly is provided with a second sleeve, a plug-in rod, a limiting hole, a square rod, a spring and a T-shaped limiting rod. When the prism assembly body needs to be disassembled, the T-shaped limiting rod is pulled to move the T-shaped limiting rod upward, and the T-shaped limiting rod will be separated from the limiting hole, releasing the limit of the square rod. At this time, the round cap is pulled to drive the square rod, the round plate and the plug-in rod to move left, so that the plug-in rod is separated from the second sleeve, and the prism assembly body can be disassembled. When the prism assembly body needs to be installed, the first sleeve is first sleeved on the rotating shaft, and the fixing block is stuck in the groove body. At this time, the T-shaped limiting rod is pulled upward, and the T The T-shaped limit rod drives the fixed plate to move up and compresses the spring, pushing the round cap to drive the square rod, round plate and plug-in rod to move right until the round plate contacts the U-shaped bracket. At this time, the T-shaped limit rod is aligned with the limit hole, and the T-shaped limit rod is released to reset the spring and push the fixed plate to move down. The fixed plate drives the T-shaped limit rod to move down and the T-shaped limit rod will be inserted into the limit hole, thereby fixing the square rod, round plate and plug-in rod, and then completing the installation of the prism assembly body. By quickly disassembling and installing the prism assembly body, the damaged prism assembly body can be easily replaced without scrapping the total station as a whole, thereby reducing the cost of use.

When the angle of the prism assembly body needs to be adjusted, the knob is turned to drive the worm gear, the worm gear and the rotating shaft to rotate. The rotating shaft drives the first sleeve and the prism assembly body to rotate through the mutual cooperation of the slot body and the fixed block, thereby realizing the angle adjustment of the prism assembly body. By adjusting the angle of the prism assembly body, the working range of the prism assembly body is improved, which is convenient for personnel to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a miniature tubular total station prism assembly, including a U-shaped bracket 1, a T-shaped box body 3 is fixedly connected to one side of the U-shaped bracket 1, and a square rod 11 is slidably connected to the T-shaped box body 3. Due to the square design of the square rod 11, the square rod 11 and the limiting hole 19 can be prevented from rotating, so that the limiting hole 19 can be quickly aligned with the T-shaped limiting rod 8, thereby improving work efficiency. A T-shaped limiting rod 8 is slidably connected to the T-shaped box body 3. Due to the provision of the T-shaped limiting rod 8, the T-shaped limiting rod 8 can prevent the spring 9 from bending when it is compressed, thereby facilitating the smooth progress of subsequent operations. A spring 9 is sleeved on the T-shaped limiting rod 8, one end of the spring 9 is fixedly connected to the T-shaped box body 3, and the other end of the spring 9 is fixedly connected to the fixed plate 10.

[0021] A fixing plate 10 is fixedly connected to the T-shaped limit rod 8, a limiting hole 19 is provided on the square rod 11, a circular plate 20 is fixedly connected to the square rod 11, a plug-in rod 18 is fixedly connected to the circular plate 20, a second sleeve 17 is rotatably connected to the plug-in rod 18, the limiting hole 19 corresponds to the position of the T-shaped limit rod 8, and the rotating shaft 13 is rotatably connected to the U-shaped bracket 1 through a bearing.

[0022] The prism assembly body 2 is fixedly connected to the second sleeve 17, and the first sleeve 15 is fixedly connected to one side of the prism assembly body 2. Two fixed blocks 16 are fixedly connected inside the first sleeve 15. A rotating shaft 13 is provided inside the first sleeve 15, and one end of the rotating shaft 13 is fixedly connected to the worm gear 5, and a worm 6 is engaged with the worm gear 5.

[0023] Two grooves 14 are provided on the rotating shaft 13, and the worm 6 is rotatably connected to the U-shaped bracket 1 through a bearing. One end of the worm 6 is fixedly connected to the knob 7. Because a number of grooves are provided on the knob 7, friction can be increased, which makes it convenient for people to turn the knob 7 and improves the convenience of operation. A tubular column 4 is provided at the bottom of the U-shaped bracket 1, and a round cap 12 is fixedly connected to the end of the square rod 11 away from the circular plate 20. Because the round cap 12 is designed as a curved surface, when a person pulls the round cap 12, the curved surface of the round cap 12 can fit the fingers, thereby improving the comfort of operation.

[0024] The working principle of this utility model is:

[0025] When the angle of the prism assembly main body 2 needs to be adjusted, the knob 7 is turned to drive the worm 6, the worm wheel 5 and the rotating shaft 13 to rotate. The rotating shaft 13 drives the first sleeve 15 and the prism assembly main body 2 to rotate through the mutual cooperation between the groove 14 and the fixed block 16, thereby achieving the angle adjustment of the prism assembly main body 2;

[0026] When the prism assembly main body 2 needs to be disassembled, the T-shaped limit rod 8 is pulled to move the T-shaped limit rod 8 upward, and the T-shaped limit rod 8 will be out of the limit hole 19, releasing the limit of the square rod 11. At this time, the round cap 12 is pulled to drive the square rod 11, the round plate 20 and the plug-in rod 18 to move left, so that the plug-in rod 18 is out of the second sleeve 17, and the prism assembly main body 2 can be disassembled. When the prism assembly main body 2 needs to be installed, the first sleeve 15 is first sleeved on the rotating shaft 13, and the fixing block 16 is stuck in the groove body 14. At this time, the T-shaped limit rod 8 is pulled upward. The T-shaped limit rod 8 drives the fixing plate 10 to move upward and compresses the spring 9, pushing the round cap 12 to drive the square rod 11, the round plate 20 and the plug-in rod 18 to move right until the round plate 20 contacts the U-shaped bracket 1. At this time, the T-shaped limit rod 8 is aligned with the limiting hole 19, and the T-shaped limit rod 8 is released to reset the spring 9 and push the fixing plate 10 to move downward. The fixing plate 10 drives the T-shaped limit rod 8 to move downward and the T-shaped limit rod 8 will be inserted into the limiting hole 19, thereby fixing the square rod 11, the round plate 20 and the plug-in rod 18, thereby completing the installation of the prism assembly main body 2.
