All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0026] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: a portable hand-held total station, including: a support plate 2, a handle 1 is installed at the bottom end of the support plate 2, a total station main body 3 is installed at the top end of the support plate 2, and a protective frame 4 is connected to the edge of the top end of the support plate 2; the handle 1 is fixedly installed at the bottom end of the support plate 2, and an anti-slip sleeve 6 is fixedly sleeved outside the handle 1, so that it is not easy to slip when holding the handle 1. Mounting plates 7 are fixedly installed on both side walls at both ends of the total station main body 3. Both mounting plates 7 are L-shaped plates. One end of both mounting plates 7 and the top end of the support plate 2 are connected with mounting screws 8. Both mounting plates 7 are fixedly connected to the support plate 2 through the mounting screws 8, which is convenient for disassembling and assembling the total station main body 3. The longitudinal section of the protective frame 4 is an inverted U shape. The bottom end of the protective frame 4 is fixedly installed at the four corners of the top end of the support plate 2. Protective sleeves 5 are fixedly sleeved at the four corners of the protective frame 4, which is convenient for protecting the corners of the protective frame 4.
[0027] Two protective covers 9 are symmetrically arranged on one side of the surveying instrument body 3. A magnetic block 10 is arranged at one end of the two protective covers 9. A moving block 12 is fixedly installed on the top of the two protective covers 9. A moving groove 14 is opened on the inner wall of the protective frame 4 close to the two moving blocks 12, and the two protective covers 9 are arranged at one end close to the lens of the surveying instrument body 3. The two protective covers 9 are both semi-cylindrical, and elastic cushions 11 are fixedly installed on the inner walls of the two protective covers 9 to protect the lens of the surveying instrument body 3. The two magnetic blocks 10 are respectively fixedly installed at the edge of one end of the two protective covers 9 away from the surveying instrument body 3. The two magnetic blocks 10 are tightly connected by magnetic attraction. When the two protective covers 9 are close to and tightly fitted, they can be difficult to separate under the action of magnetic attraction. The two moving blocks 12 are slidably installed in the adjacent moving grooves 14. The longitudinal sections of the two moving grooves 14 are both T-shaped, and a plurality of balls 13 are rotatably installed on the tops of the two moving blocks 12, so that the moving blocks 12 are not easy to get stuck when moving.
[0028] The bottom ends of the two protective covers 9 are fixedly installed with a fixing sleeve 17, and the insides of the two fixing sleeves 17 are provided with a positioning spring 16, and the bottom ends of the two positioning springs 16 are connected to the positioning rod 15, and the top ends of the support plate 2 near the two positioning rods 15 are correspondingly provided with two fixing grooves 20 and two limiting grooves 18. The top ends of the two positioning springs 16 are fixedly installed on the inner top wall of the adjacent fixing sleeves 17, and the bottom ends of the two positioning springs 16 are fixedly connected to the adjacent positioning rods 15, so that the positioning rods 15 are not easy to be separated from the fixing grooves 20 or the limiting grooves 18 under the elastic action of the positioning springs 16. The two limiting grooves 18 are respectively arranged on the side where the two fixing grooves 20 are far away from each other, so that when the two protective covers 9 are far away from each other, the two positioning rods 15 are inserted into the two limiting grooves 18 to achieve the limiting effect on the protective covers 9, so as not to affect the normal operation of the lens of the surveying instrument body 3. The bottom ends of the two positioning rods 15 slide out of the outside of the fixing sleeve 17, and a toggle piece 19 is fixedly installed on the outer wall of one end of the two positioning rods 15 away from the positioning spring 16. The two toggle pieces 19 are both L-shaped, which makes it easy to pull the positioning rods 15 out of the limiting groove 18 or the fixing groove 20 through the toggle pieces 19.
[0029] When the device is working, through the protective frame 4 installed at the top of the support plate 2, and the surveying instrument main body 3 is installed inside the protective frame 4. When the surveying instrument main body 3 slips off and falls outdoors, it can protect the surveying instrument main body 3. By sliding the moving block 12 in the moving groove 14, it is convenient to push the two protective covers 9 to move closer to or away from each other. By moving the two protective covers 9 closer to each other, they can be tightly connected under the magnetic attraction of the two magnetic attraction blocks 10. Through the positioning rod 15 slidably connected to the bottom end of the fixed sleeve 17, under the elastic action of the positioning spring 16, the positioning rod 15 can be inserted into the adjacent fixed groove 20, making the connection of the two protective covers 9 more stable, thereby facilitating the protection of the lens of the surveying instrument, and further making the surveying instrument and its lens not easily damaged, so as not to affect the normal use of the surveying instrument.
