Description

Technical Field

[0001] The utility model relates to the technical field of the installation structure of a theodolite, in particular to a laser theodolite convenient for fixing. Background Technique

[0002] A laser theodolite is a theodolite with a laser pointing device. The laser beam emitted by the laser is introduced into the telescope barrel of the theodolite, and is emitted along the sight axis direction. Based on this, alignment, positioning, angle and slope measurement, as well as large component assembly, scribing, lofting, etc. are carried out.

[0003] When in use, the laser theodolite is assembled with a tripod. By screwing the bolts on the tripod into the bottom screw holes of the laser theodolite, the rapid connection between the tripod and the theodolite is realized. However, in most cases, the theodolite is not equipped with a dedicated tripod, and the bolt sizes used on different tripods are also different, with sizes such as 1 / 4 inch, 3 / 8 inch, 5 / 8 inch, etc., making it inconvenient to fix the laser theodolite on different types of tripods. Therefore, we propose a laser theodolite convenient for fixing. Content of the Utility Model

[0025] Please refer to Figures 1-3 , the present utility model provides a technical solution: a laser theodolite that is convenient to fix, including a body 1 and a base 2. The body 1 is fixed above the base 2 through a leveling structure. The theodolite and the leveling structure have no difference from those of the existing technology theodolite, and its working principle is also the existing technology, so no further description is made for it. In addition, a spirit level can also be set on the body 1 to judge the leveling state during leveling. A handle 11 is fixed on the surface of the body 1, and the handle 11 is fixed above the surface of the body 1, and the theodolite can be held and transferred through the handle 11.

[0026] In order to enable the theodolite to be adapted to different models of tripod for installation and use, a threaded screw thread 21 is provided at the middle position of the bottom of the base 2, and a socket 211 communicating with the screw thread 21 is also provided inside the base 2. Then, a screw base 3 is connected to the screw thread 21 in a screwed manner. The rear end of the screw base 3 is integrally connected with an insertion post 4, and the insertion post 4 connected to the rear end of the screw base 3 is placed in the socket 211. A threaded screw groove 31 is provided in the screw base 3 and the insertion post 4. During installation, the bolt on the tripod is screwed into the screw groove 31 to realize the fixation of the base 2, and thus the installation and fixation of the theodolite are realized.

[0027] Since the screw base 3 is connected to the screw thread 21 in a detachable and rotatable manner, it can be removed and replaced with a screw base 3 containing screw grooves 31 of other sizes to be adapted to different models of tripods. The overall structure of the screw base 3 and the insertion post 4 containing screw grooves 31 of different sizes can be carried together in the accessory box of the theodolite.

[0028] In order to facilitate the disassembly and installation of the screw base 3, a hexagonal groove 311 is provided on the surface of the screw base 3 at the end of the screw groove 31. The hexagonal groove 311 communicates with the screw groove 31, and an internal hexagonal wrench can be inserted into the hexagonal groove 311 to facilitate the tightening or removal of the screw base 3.

[0029] A through hole 321 is formed in the side of the screw base 3. A screw hole 22 is formed inside the base 2 aligned with the through hole 321. Then, a screw rod 33 passes through the through hole 321 and the end of the screw rod 33 is screwed into the screw hole 22. A groove 32 is formed on the surface of the screw base 3 at the end of the through hole 321. The cap part of the screw rod 33 is placed in the groove 32 to prevent leakage. After the screw base 3 is locked, it can be locked by the screw rod 33 and cannot rotate, preventing the bolt from driving the screw base 3 to rotate when being screwed into or out of the screw groove 31, and preventing the screw base 3 from loosening due to the rotation driven by the bolt when the bolt is screwed.

[0030] In addition, a marking line 23 is provided on the surface of the base 2 on the side of the groove 32. The marking line 23 is aligned with the groove 32. When the screw base 3 is rotated, it is convenient to align the through hole 321 with the screw hole 22 through the marking line 23, and then the screw rod 33 is screwed in to lock.

[0031] During use, after the tripod is unfolded, the base 2 of the instrument body 1 is placed on the support of the tripod, and the screw groove 31 on the screw base 3 is aligned with the bolt on the tripod. Then, the bolt is rotated and screwed into the screw groove 31 to fix the installation of the base 2 and the instrument body 1. Then, through the leveling structure of the laser theodolite, the instrument body 1 is adjusted, and the spirit level is observed to adjust the instrument body 1 to a horizontal state. After that, the measurement work can be carried out. When the size of the bolt on the tripod does not match the screw groove 31 of the screw base 3, the screw rod 33 can be unscrewed first, and then an internal hexagon wrench is used to cooperate with the hexagonal groove 311 to rotate and unscrew the screw base 3 and the plug post 4. A combination of a screw base 3 and a plug post 4 suitable for the bolt size is taken out from the accessory box of the theodolite. Then, the screw base 3 is screwed into the screw opening 21, and the plug post 4 is placed in the socket 211. The position of the groove 32 is aligned with the marking line 23 to ensure that the through hole 321 is aligned with the screw hole 22. Then, the screw rod 33 can pass through the through hole 321 and be screwed into the screw hole 22, and the cap part of the screw rod 33 is placed in the groove 32 to lock the screw base 3 and the plug post 4. Then, the theodolite can be fixedly installed in the same way as above.
