Technical Field

[0001] This utility model relates to the field of electronic information engineering technology, and in particular to a laser slope engineering electronic theodolite. Background Technology

[0002] A theodolite is a specialized instrument for measuring horizontal and vertical angles. In surveying work, a theodolite can be used to measure horizontal angles. In engineering construction, it can be used to mark the location, angle, and elevation of a specific engineering design on the construction site, which is called construction surveying or calibration.

[0003] In the existing technology, during the erection of the electronic theodolite for laser slope engineering, the theodolite body needs to be placed on a triangular bracket and fixed by using a fastening nut to connect with the threaded rod at the bottom of the theodolite body. Since the inner top space of the triangular bracket is relatively small, the process of tightening the nut is inconvenient, which affects the erection efficiency of the theodolite. Utility Model Content

[0004] The purpose of this utility model is to solve the problem in the existing technology where, during the erection of a laser slope engineering electronic theodolite, the theodolite body needs to be placed on a triangular bracket and fixed by a fastening nut connected to the threaded rod at the bottom of the theodolite body. Due to the relatively small inner top space of the triangular bracket, the process of tightening the nut is inconvenient, which affects the erection efficiency of the theodolite. Therefore, this utility model proposes a laser slope engineering electronic theodolite.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a laser slope engineering electronic theodolite, comprising: a theodolite body and a support block, wherein a base is fixedly connected to the bottom of the theodolite body, the base is located above the support block, a fixing rod is fixedly connected to the center of the bottom of the base, the fixing rod slides through the support block, and through holes are symmetrically opened on the outer surface of the fixing rod; a fixing assembly, wherein the fixing assembly is disposed at the bottom of the support block, the fixing assembly includes a fixing plate, the top of the fixing plate is fixedly connected to the bottom of the support block, guide rods are symmetrically slidably connected between the inner walls of the support block, one end of each of the two guide rods is fixedly connected to a round block, a spring is fixedly connected between each of the two round blocks and the fixing plate, and a mounting plate is fixedly connected to the other end of the two guide rods, and limit rods are symmetrically fixedly connected to one side of the outer surface of the mounting plate.

[0006] Preferably, a pull rod is fixedly connected to the center of the outer surface of the other side of the mounting plate, and the outer surface of the limiting rod is slidably connected to the inner surface of the through hole.

[0007] Preferably, the outer surface of the fixing plate is symmetrically provided with circular grooves, and the end faces of the two limiting rods are respectively located on the inner surfaces of the two circular grooves and fit together.

[0008] Preferably, multiple U-shaped seats are fixedly connected at equal intervals at the bottom edge of the bearing block, and rotating blocks are provided on the inner side of each of the multiple U-shaped seats.

[0009] Preferably, the inner surface of the rotating block is rotatably connected to the outer surface of the U-shaped seat, and the bottom of the rotating block is provided with a mounting hole, the inner surface of which is provided with a thread.

[0010] Preferably, the top of the support block is provided with a positioning groove, and the cross-sectional areas of the base and the positioning groove are both isosceles triangular.

[0011] Preferably, the outer surface of the base fits into the inner surface of the positioning groove, and the depth of the positioning groove is less than the height of the base.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, when the theodolite is erected, by pulling the mounting plate outward, the two limiting rods are moved away from the fixed plate. This forces the circular blocks connected to the end faces of the two guide rods to compress the springs on the same side, causing the springs to deform and contract. This allows the fixed rod connected to the bottom of the theodolite body to move back to its original position after passing through the bearing block, using the spring's rebound force. This allows the two limiting rods to pass through the surface of the fixed rod until they abut against the inside of the circular groove and lock the fixed rod in place. This achieves rapid installation and greatly improves the erection efficiency of the electronic theodolite for laser slope engineering.

[0014] 2. In this utility model, by opening a positioning groove on the top of the bearing block, the theodolite body is positioned during installation and erection, preventing the through hole on the surface of the fixing rod from shifting from the position of the limiting rod, thus making it highly practical.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figures 1-4 As shown, this utility model provides a laser slope engineering electronic theodolite, including: a theodolite body 1 and a support block 3. A base 2 is fixedly connected to the bottom of the theodolite body 1, and the base 2 is located above the support block 3. A fixing rod 8 is fixedly connected to the center of the bottom of the base 2. The fixing rod 8 slides through the support block 3, and through holes 9 are symmetrically opened on the outer surface of the fixing rod 8. A fixing assembly 6 is set at the bottom of the support block 3. The fixing assembly 6 includes a fixing plate 601. The top of the fixing plate 601 is fixedly connected to the bottom of the support block 3. Guide rods 603 are symmetrically slidably connected between the inner walls of the support block 3. A round block 605 is fixedly connected to one end of each of the two guide rods 603. Both round blocks 605 are fixedly connected to the fixing plate 601. There is a spring 604, and the other ends of the two guide rods 603 are fixedly connected to the mounting plate 602. The outer surface of one side of the mounting plate 602 is symmetrically fixedly connected to the limit rod 606, and the center of the outer surface of the other side of the mounting plate 602 is fixedly connected to the pull rod 608. The outer surface of the limit rod 606 is slidably connected to the inner surface of the through hole 9. The outer surface of the fixing plate 601 is symmetrically provided with circular grooves 607. The end faces of the two limit rods 606 are respectively located on the inner surface of the two circular grooves 607. Multiple U-shaped seats 4 are fixedly connected at equal intervals at the bottom edge of the bearing block 3. Rotating blocks 5 are provided on the inner side of each of the multiple U-shaped seats 4. The inner surface of the rotating block 5 is rotatably connected to the outer surface of the U-shaped seat 4. The bottom of the rotating block 5 is provided with a mounting hole, and the inner surface of the mounting hole is provided with a thread.

[0025] The overall effect of Embodiment 1 is that, when using the electronic theodolite in laser slope engineering, multiple U-shaped seats 4 are equidistantly fixed at the bottom edge of the bearing block 3. Rotating blocks 5 are rotatably connected to the outer surfaces of each of the multiple U-shaped seats 4, facilitating the installation of the support rods by threaded connection to the rotating blocks 5. When erection is required, the theodolite body 1 is vertically placed on top of the bearing block 3, and the fixing rod 8 connected at the bottom center of the base 2, when vertically penetrating the central hole of the bearing block 3, cooperates with pulling the pull rod 608 outward to move the mounting plate 602 away from the fixing plate 601, so that the two guide rods 603... During the movement, the circular block 605 connected to its end face will squeeze the spring 604, causing it to deform and contract, which facilitates the movement of the two limiting rods 606 away from the fixing plate 601. When the base 2 abuts against the bottom of the positioning groove 7, the positions of the two through holes 9 opened on the surface of the fixing rod 8 will be aligned with the positions of the two limiting rods 606. The rebound force of the spring 604 will push the guide rod 603 to reset and move, so that the two limiting rods 606 will pass through the two aligned through holes 9 at the same time and abut against the circular groove 607, which plays a role in rapid installation and greatly improves the erection efficiency of the laser slope engineering electronic theodolite.

[0026] Example 2: Figures 1-4 As shown, the top of the support block 3 is provided with a positioning groove 7. The cross-sectional areas of the base 2 and the positioning groove 7 are both isosceles triangular. The outer surface of the base 2 is in contact with the inner surface of the positioning groove 7. The depth of the positioning groove 7 is less than the height of the base 2.

[0027] The effect achieved by the entire embodiment 2 is that, during use, by opening a positioning groove 7 on the top of the bearing block 3, the theodolite body 1 is positioned during installation and erection, preventing the through hole 9 on the surface of the fixing rod 8 from shifting from the position of the limiting rod 606, thus achieving high practicality.

[0028] Working Principle: When using the electronic theodolite in laser slope engineering, multiple U-shaped seats 4 are equidistantly fixed at the bottom edge of the bearing block 3. Rotating blocks 5 are rotatably connected to the outer surfaces of each U-shaped seat 4, facilitating the installation of the support rods by threaded connection to the rotating blocks 5. When erection is required, the theodolite body 1 is vertically placed on top of the bearing block 3. When the fixing rod 8 connected at the bottom center of the base 2 vertically penetrates the central hole of the bearing block 3, it cooperates with the outward pulling rod 608 to move the mounting plate 602 away from the fixing plate 601. During the movement of the two guide rods 603, the round blocks 605 connected to their end faces compress the springs 604, causing... Its deformation and contraction facilitate the movement of the two limiting rods 606 away from the fixing plate 601. When the base 2 abuts against the bottom of the positioning groove 7, the positions of the two through holes 9 on the surface of the fixing rod 8 will be aligned with the positions of the two limiting rods 606. The rebound force of the spring 604 pushes the guide rod 603 to reset and move, so that the two limiting rods 606 will pass through the two aligned through holes 9 simultaneously and abut against the circular groove 607, which plays a role in quick installation. By opening the positioning groove 7 on the top of the bearing block 3, the theodolite body 1 is positioned during installation and erection, preventing the through holes 9 on the surface of the fixing rod 8 from shifting from the positions of the limiting rods 606, which is highly practical.
