Description

Technical Field

[0001] This utility model belongs to the field of total station technology and relates to a sunshade device for a total station that is easy to carry and use. Background Technology

[0002] A total station, also known as a total station electronic distance measuring instrument, is a high-tech surveying instrument integrating optics, mechanics, and electronics. It is a surveying instrument system that integrates the functions of measuring horizontal angles, vertical angles, distances, and elevation differences. Compared with optical theodolites, electronic theodolites replace the optical scale with a photoelectric scanning scale, and replace manual optical micrometer readings with automatic recording and display of readings, simplifying angle measurement operations and avoiding reading errors. When a total station is exposed to sunlight for a long time, the temperature will be too high, which can easily cause the electronic equipment to age and affect the measurement accuracy. Therefore, a sunshade device is used in conjunction with the total station during the measurement process.

[0003] The existing utility model patent with publication number CN217110934U discloses a sunshade device for a total station, which describes that "it includes a support rod, a sunshade plate, and an extension plate. Two support rods are arranged side by side, and the lower end of each support rod is provided with a buckle hole for cooperating with the bracket of the total station. The sunshade plate is located between the two support rods, and the upper end of each support rod is rotatably connected to the sunshade plate. The upper end of each support rod is fixed to the sunshade plate by a fixing member. The lower end surface of the sunshade plate is slidably connected to the extension plate, and the extension plate is fixed to the sunshade plate by an adjusting member."

[0004] When using the total station sunshade device provided by the above patent to shade the total station, the shading effect is achieved by carrying a separate external device connected to the total station or placing it separately. When used outdoors, it needs to be carried separately. If it is forgotten, the total station cannot be shaded, which will also increase the labor intensity of workers and has low practicality. Utility Model Content

[0005] The purpose of this utility model is to provide a ventilation device for mine safety, which aims to improve the problem that the existing total station sunshade device needs to be carried separately, and if it is forgotten, the total station cannot be shaded, resulting in low practicality.

[0006] This utility model discloses a portable sunshade device for a total station, comprising a connecting base, a total station body fixed to the inner side of the connecting base, a sunshade top plate at the top of the connecting base, first limiting sliders fixed to both ends of the sunshade top plate, the first limiting sliders being slidably connected to the connecting base, a fixing strip fixed to the end of the sunshade top plate away from the connecting base, side sunshades on both sides of the end of the sunshade top plate near the fixing strip, a rotating shaft fixedly connected to the end of the side sunshades near the sunshade top plate, the rotating shaft being rotatably connected to the sunshade top plate and the fixing strip respectively, the end of the rotating shaft near the fixing strip extending to the inner side of the fixing strip, second limiting sliders fixed to both sides of the fixing strip, the second limiting sliders being slidably connected to the sunshade top plate, and an adjustment component provided on the inner side of the fixing strip at a position corresponding to the rotating shaft.

[0007] Preferably, the adjusting assembly includes a fixed gear, which is fixed at one end of the rotating shaft located inside the fixed bar. A positioning rack is provided inside the fixed bar and above the fixed gear. The positioning rack is meshed with the fixed gear and slidably connected to the fixed bar. A connecting rod is fixed to the top of the positioning rack, and the end of the connecting rod away from the positioning rack extends to the outside of the fixed bar. The connecting rod is slidably connected to the fixed bar.

[0008] Preferably, a lifting plate is fixed to one end of the connecting rod located outside the fixing strip, and a telescopic spring is sleeved on the outside of the end of the connecting rod near the positioning rack. One end of the telescopic spring is fixedly connected to the fixing strip, and the other end of the telescopic spring is fixedly connected to the positioning rack.

[0009] Preferably, the first limiting slider near the fixing strip and the second limiting slider away from the sunshade top plate are both provided with positioning grooves, and a positioning component is provided on the inner side of the connecting base at a position corresponding to the positioning groove.

[0010] Preferably, the positioning component includes a positioning screw, which is disposed at a position corresponding to the positioning groove on the connecting base. The positioning screw is rotatably connected to the connecting base. A positioning knob is fixed at one end of the positioning screw away from the connecting base.

[0013] Compared with the prior art, the beneficial effects of this utility model are: through the cooperative structural design of the connecting base, the sunshade top plate, the side sunshade plates and the adjustment components, the two side sunshade plates can be folded to the top of the sunshade top plate when no sunshade is needed, and then stored inside the top of the connecting base, thus forming an integral whole with the connecting base. This eliminates the need to carry other sunshade equipment, effectively improving the portability of the device and reducing the labor intensity of workers.

[0014] Through the combined structural design of the stop block, positioning block, moving rod, lever plate and limit spring, the side sunshade can be fixed by the clamping action of the positioning block and the stop block when encountering strong winds outdoors. In this way, the side sunshade can provide sun and rain protection for the total station body, effectively improving the stability of the side sunshade and enhancing the practicality of the device.

[0024] Example 1

[0025] like Figures 1-5 As shown, the device includes a connecting base 1, a total station body 2 fixed to the inner side of the connecting base 1, a sunshade top plate 3 at the top of the connecting base 1, and a first limiting slider 7 fixed to both ends of the sunshade top plate 3 for easy positioning. The first limiting slider 7 is slidably connected to the connecting base 1. A fixing strip 5 is fixed to the end of the sunshade top plate 3 away from the connecting base 1. To provide sunshade for the total station body 2 and prevent strong light from affecting the total station body 2, side sunshades 4 are provided on both sides of the end of the sunshade top plate 3 near the fixing strip 5. A rotating shaft 6 is fixedly connected to the end of the side sunshade 4 near the sunshade top plate 3. The rotating shaft 6 is rotatably connected to the sunshade top plate 3 and the fixing strip 5 respectively. The end of the rotating shaft 6 near the fixing strip 5 extends to the inner side of the fixing strip 5. A second limiting slider 8 is fixed to both sides of the fixing strip 5. The second limiting slider 8 is slidably connected to the sunshade top plate 3. An adjustment component is provided on the inner side of the fixing strip 5 at a position corresponding to the rotating shaft 6.

[0026] Through the coordinated structural design of the connecting base 1, the sunshade top plate 3, the side sunshade plates 4 and the adjustment components, the two side sunshade plates 4 can be folded to the top of the sunshade top plate 3 when no sunshade is needed, and then stored inside the top of the connecting base 1, thus forming a whole with the connecting base 1. This eliminates the need to carry other sunshade equipment, effectively improving the portability of the device and reducing the labor intensity of workers.

[0027] Example 2

[0028] like Figures 2-5 As shown, the adjustment assembly includes a fixed gear 13, which is fixed to one end of the rotating shaft 6 located inside the fixed bar 5. A positioning rack 14 is provided inside the fixed bar 5 and above the fixed gear 13. To facilitate the limiting of the rotating shaft 6 by the positioning rack 14 and the fixed gear 13, the positioning rack 14 is meshed with the fixed gear 13 and slidably connected to the fixed bar 5. To facilitate the movement of the positioning rack 14, a connecting rod 15 is fixed to the top of the positioning rack 14. The end of the connecting rod 15 away from the positioning rack 14 extends to the outside of the fixed bar 5 and slidably connects to the fixed bar 5.

[0029] To facilitate the movement of the connecting rod 15, a lifting plate 17 is fixed to one end of the connecting rod 15 located outside the fixing bar 5. To facilitate the limiting of the positioning rack 14, a telescopic spring 16 is sleeved on the outer side of the end of the connecting rod 15 near the positioning rack 14. One end of the telescopic spring 16 is fixedly connected to the fixing bar 5, and the other end of the telescopic spring 16 is fixedly connected to the positioning rack 14.

[0030] When sun shading is required, firstly, the positioning component releases the limit on the second limiting slider 8. Then, by pulling the fixing bar 5 away from the connecting base 1, the fixing bar 5 moves the sunshade top plate 3. When the side sunshade 4 moves to the outside of the connecting base 1, stop pulling the fixing bar 5. Then, pull the lifting plate 17 away from the fixing bar 5, so that the lifting plate 17 moves the positioning rack 14 through the connecting rod 15. When the positioning rack 14 moves to disengage from the fixed gear 13, the positioning rack 14 releases the limit on the fixed gear 13. Then, by rotating the side sunshade 4, adjust the side sunshade 4 to a suitable sunshade position. Then, release the lifting plate 17. At this time, under the elastic action of the telescopic spring 16, the positioning rack 14 moves to mesh with the fixed gear 13, so that the rotation of the rotating shaft 6 is limited by the fixed gear 13. Since the side sunshade 4 is fixedly connected to the rotating shaft 6, the angle of the side sunshade 4 is fixed.

[0031] Example 3

[0032] like Figure 2 and Figure 3As shown, the first limiting slider 7 near the fixed strip 5 and the second limiting slider 8 away from the sunshade top plate 3 are both provided with positioning grooves 9, and a positioning component is provided on the inner side of the connecting base 1 at a position corresponding to the positioning groove 9.

[0033] The positioning assembly includes a positioning screw 11, which is positioned at a location corresponding to the positioning groove 9 on the connecting base 1. The positioning screw 11 is rotatably connected to the connecting base 1. To facilitate rotation of the positioning screw 11, a positioning knob 12 is fixed to one end of the positioning screw 11 away from the connecting base 1. The other end of the positioning screw 11 is threadedly connected to a positioning bolt 10, which is slidably connected to the connecting base 1. The positioning bolt 10 is inserted into and connected to the first limiting slider 7 or the second limiting slider 8 through the positioning groove 9.

[0034] During operation, firstly, by rotating the positioning knob 12, the positioning screw 11 is rotated. When the positioning screw 11 rotates, the positioning bolt 10, which is threaded to it, moves along the axial direction of the positioning screw 11. When the positioning bolt 10 moves to the point of disengaging from the positioning groove 9, the positioning bolt 10 releases its restriction on the second limiting slider 8. At this time, the sunshade top plate 3 can be moved away from the connecting base 1 by pulling the fixing bar 5. When the sunshade top plate 3 moves to the position corresponding to the positioning groove 9 on the first limiting slider 7 and the positioning bolt 10, the positioning knob 12 is rotated in the opposite direction, causing the positioning screw 11 to move the positioning bolt 10 closer to the first limiting slider 7. When the positioning bolt 10 moves to the inside of the positioning groove 9, the positioning bolt 10 completes the restriction on the first limiting slider 7, thereby completing the fixation of the sunshade top plate 3.

[0035] Example 4

[0036] like Figure 5 As shown, both sides of the connecting base 1 near the side sun visor 4 are fixed with blocks 18. A positioning block 19 is slidably connected to the inner side of the connecting base 1 at a position corresponding to the blocks 18. Through the structural design of the blocks 18 and the positioning block 19, the side sun visor 4 can be auxiliaryly clamped, improving the stability of the side sun visor 4. A moving rod 20 is fixed to the end of the positioning block 19 away from the side sun visor 4. The end of the moving rod 20 away from the positioning block 19 extends to the outer side of the connecting base 1. The moving rod 20 is slidably connected to the connecting base 1. A lever 21 is fixed to the end of the moving rod 20 located on the outer side of the connecting base 1.

[0037] A limiting spring 22 is fixed to one end of the positioning block 19 located inside the connecting base 1, and the end of the limiting spring 22 away from the positioning block 19 is fixedly connected to the connecting base 1.

[0038] When encountering strong winds, firstly, pull the lever 21 towards the connecting base 1, causing the lever 21 to move the positioning block 19 via the moving rod 20. When the positioning block 19 moves to the inside of the connecting base 1, the end of the side sun visor 4 away from the rotating shaft 6 can be rotated to a position that fits against the stop block 18. Then, release the lever 21. At this time, under the elastic action of the limiting spring 22, the positioning block 19 is pushed towards the side sun visor 4, thereby causing the positioning block 19 to move out to the outside of the connecting base 1. Then, the side sun visor 4 is clamped by the cooperation of the positioning block 19 and the stop block 18, preventing damage to the side sun visor 4 in strong winds and improving the stability of the side sun visor 4.

[0039] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
