Description

Technical Field

[0001] The utility model belongs to the technical field of surveying and mapping equipment, and in particular relates to a sunshade with adjustable direction for field surveying. Background Art

[0002] When performing high-precision field measurements, in order to prevent the measuring instrument from being exposed to the sun or rain for a long time, which would cause the accuracy of the measuring instrument to decrease, a dedicated person is often required to hold an umbrella to shade the measuring instrument. When performing high-precision measurements, a dedicated person holding an umbrella to shade the measuring instrument is not only inefficient but may also increase the measurement cost.

[0003] The existing technology only solves the problem of shading the measuring instrument in a certain light direction. It is impossible to arbitrarily change the shading direction of the parasol as the sunlight moves. For example, a patent document with the publication number CN2066670U discloses "a kind of bendable umbrella". A matching pipe sleeve is used to connect the middle section and the lower section of the umbrella handle to form an umbrella body rotation mechanism. The umbrella surface can be adjusted to tilt at a certain angle relative to the umbrella handle. However, since the umbrella surface can only be adjusted in a single degree of freedom direction, it is still impossible to achieve arbitrary adjustment of the shading direction, and flexibility and practicality are still lacking. Therefore, it is particularly important to design a new device invention that is practical, simple to operate, economical, and reusable. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer and more understandable, the technical solution of the utility model will be further described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model provides a direction-adjustable parasol for field measurement, comprising a parasol 1, a front-and-rear rotation adjustment device 3, a horizontal rotation adjustment device 2 and a support platform 4, a horizontal rotation shaft 19 is rotatably mounted on the support platform 4, the horizontal rotation adjustment device 2 is used to drive the horizontal rotation shaft 19 to rotate, the front-and-rear rotation adjustment device 3 is fixedly connected to the horizontal rotation shaft 19, the parasol 1 is detachably connected to the front-and-rear rotation adjustment device 3, the front-and-rear rotation adjustment device 3 is used to drive the parasol 1 to perform rotation adjustment in the front-and-rear direction, and a plurality of support legs 5 are arranged on the bottom surface of the support platform 4.

[0020] The horizontal rotation adjustment device 2 can drive the horizontal rotation axis 19 to rotate horizontally. Since the front and rear rotation adjustment device 3 is fixedly connected to the horizontal rotation axis 19, when the horizontal rotation axis 19 rotates, it can directly drive the front and rear rotation adjustment device 3 to rotate synchronously. The front and rear rotation adjustment device 3 can drive the parasol 1 to rotate and adjust in the front and rear directions. Therefore, the combination of the horizontal rotation adjustment device 2 and the front axle rotation adjustment device 3 can drive the parasol 1 to rotate in the horizontal direction and the front and rear directions as a whole, thereby changing the shading direction.

[0021] The horizontal rotation adjustment device 2 includes a driven gear 20 and a driving gear 21. The driven gear 20 is fixedly mounted on the horizontal rotation shaft 19. The driving gear 21 is rotatably mounted on the support platform 4 and meshes with the driven gear 20. A support baffle 24 is fixedly provided on the support platform 4. A sleeve 29 is fixedly provided on the top of the support baffle 24. A center shaft 23 is fixedly provided on the driving gear 21. The center shaft 23 is rotatably inserted in the sleeve 29. A rotating nut 22 is provided on the center shaft 23.

[0022] The support baffle 24 is fixed to the support platform 4, the sleeve 29 is fixed to the support baffle 24, and the central axis rotation 23 fixedly connected to the driving gear 21 is rotatably inserted in the sleeve 29, so the driving gear 21 can only rotate relative to the support platform 4. At this time, the staff only needs to rotate the rotating nut 22 to directly drive the driving gear 21 to rotate, and the driving gear 21 is meshed with the driven gear 20, so when the driving gear 21 rotates, it can drive the driven gear 20 to rotate. Because the driven gear 20 is fixedly connected to the horizontal rotating shaft 19, and the horizontal rotating shaft 19 is rotatably installed on the support platform 4, when the driven gear 20 rotates, it can drive the horizontal rotating shaft 19 to rotate and adjust in the horizontal direction.

[0023] The front and rear rotation adjustment device 3 includes a track base plate 14, a fixed baffle 13 and a screw 13. The track base plate 14 is fixedly connected to the top end of the horizontal rotation axis 19. The fixed baffle 16 is fixedly connected to one end of the track base plate 14. The screw 13 is fixedly installed on the fixed baffle 16. The screw 13 is provided with a U-shaped active head 10 through threaded fitting. The handle of the parasol 1 is detachably inserted in the U-shaped active head 10 through threaded fitting. A movable baffle 11 is slidably fitted on the screw 13. An adjusting nut 12 is provided on the screw 13 on the outer side of the movable baffle 11 through threaded fitting. A slide groove 15 is provided on the track base plate 14. The bottom end of the movable baffle 11 is slidably embedded in the slide groove 15.

[0024] Since the U-shaped active head 10 is mounted on the screw rod 13 through threaded cooperation, when in use, the U-shaped active head 10 can be rotated according to needs to make it rotate in the front and rear directions to adjust the position and direction of the parasol 1. After completion, the staff only needs to rotate the adjusting nut 12. Since the adjusting nut 12 and the screw rod 13 are threadedly cooperated, the adjusting nut 12 will move along the axial direction of the screw rod 13 when it rotates. At this time, the adjusting nut 12 can be moved in the direction of the U-shaped active head 10, pushing the movable baffle 11, so that the movable baffle 11 slides along the slide groove 15, approaches and squeezes the U-shaped active head 10, so that the U-shaped active head 10 can be positioned to prevent it from being rotated by external wind or the hardness of the parasol 1's own weight, thereby changing the direction and position of the parasol 1.

[0025] To sum up, the overall usage process of the utility model is as follows: first, move the device to a suitable position, insert the supporting legs 5 into the ground to fix the device, and then the staff needs to rotate the U-shaped flexible head 10 to make it rotate to a suitable direction, and then insert the handle of the parasol 1 into the U-shaped flexible head 10 through threaded cooperation. Then the staff opens the parasol 1, pushes and pulls the handle of the parasol 1, so that the U-shaped flexible head 10 rotates slightly, and fine-tunes the direction of the parasol 1. After it is suitable, turn the adjusting nut 12, push the movable baffle 11 close to and squeeze the U-shaped flexible head 10 to fix it. After completion, the staff needs to rotate the rotating nut 22 to drive the driven gear 20 to rotate, so that the horizontal rotating shaft 19 rotates, and then the parasol 1 rotates in the horizontal direction to adjust its horizontal direction and position. After completion, the entire adjustment work can be completed and the subsequent external surveying and mapping work can be started.
