Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of total stations, in particular to an anti-reflective and easy-to-adjust total station. Background Art
[0002] A total station, also known as a total station electronic tachometer, is an instrument that can automatically display necessary observation data such as slant distance, zenith distance, horizontal angle, etc. once observation is made on a side station, and the horizontal distance, elevation difference and coordinates of the point can be obtained almost at the same time. If the data terminal collected in the field by the total station tachometer is connected to a computer or plotter through a transmission interface, and equipped with data processing software and drawing software, the automation of mapping can be realized.
[0003] Existing total stations are prone to light reflection and light interference in strong light environments, especially in summer, which affects measurement accuracy. When the total station is rotated to observe the telescope, it is often facing strong light, which affects the normal measurement readings. Light reflection and light interference not only reduce measurement accuracy, but may also cause inaccurate measurement data. For example, in strong sunlight, the lens and reflector of the total station may reflect sunlight, causing glare, making it difficult for surveyors to see the target clearly. In addition, the reflected sunlight may also interfere with the internal optical system of the total station, causing deviations in the measurement results. Utility Model Content
[0004] The technical problem to be solved by the utility model is that the existing technology has the disadvantage that the total station is easily affected by light reflection and interference in a strong light environment, resulting in measurement deviation. For this reason, we propose a total station that is anti-reflective and easy to adjust.
[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical solution: an anti-reflective and easy-to-adjust total station, comprising a total station body, two U-shaped shells fixedly connected on both sides of the total station body, a movable groove is provided at one end of the U-shaped shell, an extension plate is slidably connected inside the movable groove, fixed blocks are fixedly connected on both sides of the U-shaped shell, movable grooves are provided on both sides of the extension plate, a plurality of tooth blocks are fixedly connected inside the movable groove, notches are provided on both sides of the U-shaped shell, the top of the fixed block is fixedly connected to a sleeve, the inside of the sleeve is rotatably connected to a first connecting rod, the top of the first connecting rod is fixedly connected to a gear, the top of the gear is fixedly connected to a second connecting rod, and the top of the second connecting rod is fixedly connected to a toggle rod.
[0006] Preferably, a plurality of cutout grooves are provided on the surface of the toggle lever.
[0007] Preferably, a U-shaped block is fixedly connected to the top of the fixed block, and a clamping block is rotatably connected to the internal rotating shaft of the U-shaped block.
[0008] Preferably, the top and bottom of the inner cavity of the movable groove are both provided with limiting grooves, and the top and bottom of the extension plate are both fixedly connected to limiting blocks.
[0009] Preferably, the surfaces of the U-shaped shell and the extension plate are coated with aluminum foil paint.
[0010] Preferably, the outer shape of the clamping block matches the inner shape of the tooth opening at the top of the gear.
[0011] Technical effects and advantages of this utility model:
[0012] In the utility model, the staff rotates the two toggle rods, which can accurately drive the second connecting rod to rotate. Under the action of the toggle rods, the second connecting rod starts to move, thereby driving the gear to rotate accurately. During the rotation of the gear, the tooth block engaged on one side of the gear also moves accordingly, allowing the extension plate to move smoothly out from the inside of the U-shaped shell, effectively reducing the reflection of external light, thereby significantly improving the clarity and accuracy of the observation equipment. By reducing reflection, the observation equipment can more accurately capture the details of the target object, making the observation results more reliable and accurate.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.
[0020] Reference Figure 1 - Figure 4 As shown, the utility model provides a technical solution: an anti-reflective and easy-to-adjust total station, comprising a total station body 1, two U-shaped shells 2 are fixedly connected on both sides of the total station body 1, a movable groove 3 is provided at one end of the U-shaped shell 2, an extension plate 4 is slidably connected inside the movable groove 3, a fixed block 5 is fixedly connected on both sides of the U-shaped shell 2, a movable groove 6 is provided on both sides of the extension plate 4, a plurality of tooth blocks 7 are fixedly connected inside the movable groove 6, a notch 18 is provided on both sides of the U-shaped shell 2, a sleeve 8 is fixedly connected to the top of the fixed block 5, a first connecting rod 9 is rotatably connected inside the sleeve 8, and a first connecting rod 9 is rotatably connected inside the sleeve 8. A gear 10 is fixedly connected to the top of a connecting rod 9, a second connecting rod 11 is fixedly connected to the top of the gear 10, and a toggle rod 12 is fixedly connected to the top of the second connecting rod 11. The staff rotates the two toggle rods 12 to make the toggle rod 12 drive the second connecting rod 11, and then drive the gear 10 to rotate, so that the tooth block 7 engaged with one side of the gear 10 moves, and the extension plate 4 moves out from the inside of the U-shaped shell 2, thereby effectively reducing the reflection of external light. By reducing the reflection, the clarity and accuracy of the observation equipment are significantly improved, making the observation results more reliable and accurate.
[0021] Reference Figure 3 and Figure 4 As shown, in this embodiment: a plurality of cutout grooves 13 are provided on the surface of the toggle lever 12. By providing a plurality of cutout grooves 13 on the surface of the toggle lever 12, the friction between the toggle lever 12 and the fingers can be increased when the staff rotates the toggle lever 12 by hand, making it more labor-saving and convenient for the staff to use.
[0022] Reference Figure 4 As shown, in this embodiment: the top of the fixed block 5 is fixedly connected to the U-shaped block 14, and the internal rotating shaft of the U-shaped block 14 is rotatably connected to the clamping block 15. When the extension plate 4 is moved out from the interior of the U-shaped shell 2, the clamping block 15 is moved downward so that the clamping block 15 is engaged with the tooth mouth at the top of the gear 10 to limit the gear 10. This can ensure that the gear 10 stops rotating at a specific position and prevent the extension plate 4 from being displaced.
[0023] Reference Figure 5 As shown, in this embodiment: limiting grooves 16 are provided at the top and bottom of the inner cavity of the movable groove 3, and limiting blocks 17 are fixedly connected to the top and bottom of the extension plate 4. By cooperating with the limiting blocks 17 and the limiting grooves 16, the movement trajectory of the extension plate 4 can be restricted to prevent it from excessive displacement and falling off from the inside of the U-shaped shell 2.
[0024] Reference Figure 1As shown, in this embodiment: the surfaces of the U-shaped shell 2 and the extension plate 4 are coated with aluminum foil paint, which can effectively block direct sunlight and reduce visual discomfort caused by strong light exposure. At the same time, the aluminum foil paint has good corrosion resistance.
[0025] Reference Figure 3 and Figure 4 As shown, in this embodiment: the external shape of the block 15 is consistent with the internal shape of the tooth opening at the top of the gear 10. When the external shape of the block 15 is consistent with the internal shape of the tooth opening, it is ensured that the block 15 can be accurately embedded in the tooth opening at the top of the gear 10, which not only improves the stability of the connection, but also avoids misalignment or loosening.
[0026] Working principle: The staff rotates the two toggle rods 12 to make the toggle rods 12 drive the second connecting rod 11, and then drive the gear 10 to rotate, so that the tooth block 7 engaged with one side of the gear 10 moves, and the extension plate 4 moves out from the inside of the U-shaped shell 2, thereby effectively reducing the reflection of external light. By reducing the reflection, the clarity and accuracy of the observation equipment are significantly improved, making the observation results more reliable and accurate. By providing a plurality of cutout grooves 13 on the surface of the toggle rod 12, the friction between the toggle rod 12 and the fingers can be increased when the staff rotates the toggle rod 12 by hand, making it more labor-saving and convenient for the staff to use. When the extension plate 4 is moved out from the inside of the U-shaped shell 2, it is moved downward. The clamping block 15 is engaged with the tooth mouth at the top of the gear 10 to limit the gear 10, which can ensure that the gear 10 stops rotating at a specific position and prevent the extension plate 4 from being displaced. By cooperating with the limiting block 17 and the limiting groove 16, the movement trajectory of the extension plate 4 can be limited to avoid excessive displacement and falling off from the inside of the U-shaped shell 2. The aluminum foil coating can effectively block direct sunlight and reduce visual discomfort caused by strong light. At the same time, the aluminum foil coating has good corrosion resistance. When the external shape of the clamping block 15 matches the internal shape of the tooth mouth, it ensures that the clamping block 15 can be accurately embedded in the tooth mouth at the top of the gear 10, which not only improves the stability of the connection, but also avoids dislocation or loosening.
