Description

Technical Field

[0001] This utility model relates to the field of theodolite equipment technology, specifically to an electronic theodolite for engineering testing. Background Technology

[0002] Electronic theodolites are automated, high-precision optical measuring instruments that play an important role in engineering inspection and measurement. They are widely used in railways, highways, bridges, water conservancy, and mining, and can also be used for construction and the installation of large equipment. They are applied to cadastral surveying, topographic surveying, and various engineering surveys.

[0003] The core components of an electronic theodolite mainly include an optical system, an electronic system, and a precision mechanical structure. These components are quite sensitive to environmental factors such as temperature, humidity, and light. However, in actual use, electronic theodolites are mostly used outdoors. In environments with strong light, the optical and electronic systems of the electronic theodolite may be damaged, and the mechanical structure may also deform due to high temperatures. At the same time, in some rainy or snowy weather, the theodolite is easily wetted by rain and snow, which may lead to unstable performance or damage. The optical system may also be damaged by moisture. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing an electronic theodolite for engineering testing, thereby solving the problems mentioned in the background art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An electronic theodolite for engineering testing includes a tripod support frame, the top end face of which is fixedly connected to the theodolite body, and the top surface of the theodolite body is provided with a protective body component.

[0007] The theodolite body includes a body base, a frame fixed to the upper surface of the body base, and a telescope body rotatably disposed between the inner sides of the frame, and a control knob and a control panel are installed on the front end face of the frame;

[0008] The protective components of the machine body include connecting plates fixedly connected to the left and right side walls of the frame, and lower clamps fixedly connected to the opposite sides of the connecting plates. An upper clamp is hinged to the rear end of the lower clamp. A rotating column is engaged between the lower clamp and the upper clamp. A support rod is fixed to the opposite end of each rotating column. An arched protective plate is fixedly connected to the top of the support rod.

[0009] As a preferred embodiment of an electronic theodolite for engineering testing, the rear ends of the lower clamp and the upper clamp are hinged by a pivot pin, and the front end of the lower clamp is rotatably connected to a screw that passes through the front end of the upper clamp.

[0010] As a preferred embodiment of an electronic theodolite for engineering testing, a groove is formed on the outer surface of the rotating column, and a rubber ring is adhered and fixed to the outer ring of the groove by an adhesive.

[0011] As a preferred embodiment of an electronic theodolite for engineering testing, both the upper and lower clamps have arc-shaped grooves on their inner surfaces that couple with the outer surface of the rubber ring.

[0012] As a preferred embodiment of an electronic theodolite for engineering testing, the vertical cross-section of the arched protective plate is arc-shaped, and there is a 3-5cm gap between the bottom surface of the arched protective plate and the top of the theodolite body.

[0013] As a preferred embodiment of an electronic theodolite for engineering testing, the ends of the rotating columns that are close to each other are spaced 1-2 cm apart from the surfaces of the connecting plates that are far apart.

[0014] As a preferred embodiment of an electronic theodolite for engineering testing, the tripod support frame includes a base and three support legs arranged in a circular array and hinged to the bottom end face of the base.

[0015] As a preferred embodiment of an electronic theodolite for engineering testing, the bottom end face of the machine body base is locked to the top end face of the base by screws.

[0016] The beneficial effects of this utility model are:

[0017] This invention provides protective components on both sides of the electronic theodolite's body to shield the top of the theodolite. In summer, this prevents direct sunlight from hitting the theodolite. The protective components can be adjusted according to the angle of sunlight, preventing the theodolite from overheating due to sunlight. Furthermore, in rainy or snowy weather, the protective components prevent rainwater from entering the theodolite, thus avoiding damage to the optical system due to moisture intrusion.

[0030] like Figure 1 As shown, this utility model provides an electronic theodolite for engineering testing, including a tripod support frame 1, with the theodolite body 2 fixedly connected to the top end face of the tripod support frame 1, and an organic protective component 3 provided on the top surface of the theodolite body 2.

[0031] like Figure 2 As shown, the theodolite body 2 specifically includes a body base 21, a frame 23 fixed on the upper surface of the body base 21, and a telescope body 22 rotatably disposed inside the frame 23. The front end face of the frame 23 is equipped with a control knob 24 and a control panel.

[0032] like Figure 3 and Figure 4 As shown, the protective component 3 of the machine body specifically includes a connecting plate 35 fixedly connected to the left and right side walls of the frame 23, and a lower clamp 37 fixedly connected to the side of the connecting plate 35 that is far apart from each other. An upper clamp 34 is hinged to the rear end of the lower clamp 37. A rotating column 33 is engaged between the lower clamp 37 and the upper clamp 34. A support rod 31 is fixed to the far end of the rotating column 33. An arched protective plate 32 is fixedly connected to the top of the support rod 31.

[0033] Specifically, in this embodiment, the rear ends of the lower clamp 37 and the upper clamp 34 are hinged by a pivot pin. The front end of the lower clamp 37 is rotatably connected to a screw 36 that passes through the front end of the upper clamp 34. A groove 39 is provided on the outer surface of the rotating column 33. A rubber ring 38 is adhered and fixed on the outer ring of the groove 39 by an adhesive.

[0034] More specifically, the inner surfaces of both the upper clamp 34 and the lower clamp 37 are provided with arc-shaped grooves that couple with the outer surface of the rubber ring 38. The vertical cross-section of the arched protective plate 32 is arc-shaped, and there is a 3-5cm gap between the bottom surface of the arched protective plate 32 and the top of the theodolite body 2; the ends of the rotating columns 33 that are close to each other are 1-2cm apart from the side surfaces of the connecting plate 35 that are far apart from each other.

[0035] like Figure 5As shown, the tripod support frame 1 specifically includes a base 11 and three support legs 12 that are arranged in a ring array and hinged to the bottom end face of the base 11; the bottom end face of the body base 21 is locked to the top end face of the base 11 by screws.

[0036] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:

[0037] In rainy, snowy, or sunny conditions, first insert one side of the rotating column 33 between the upper clamp 34 and the lower clamp 37, and then insert the other side of the rotating column 33 between the upper clamp 34 and the lower clamp 37. While the upper clamp 34 and the lower clamp 37 are not fully engaged, allow the support rod 31 and the arched protective plate 32 to rotate axially along the axis of the rotating column 33 until the arched protective plate 32 blocks sunlight or rain and snow without obstructing the view of the telescope body 22, preventing direct sunlight from shining on the theodolite body 2 or rain from wetting the theodolite body 2. Then, lock the lower clamp 37 and the upper clamp 34 together with the screw 36. The rubber ring 38 and the friction between the upper clamp 34 and the lower clamp 37 provide stable support for the support rod 31 and the arched protective plate 32.

[0038] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
