Detailed Implementation

[0022] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0023] Example: A surveying device for construction engineering, such as... Figures 1-6 As shown, the device includes a triangular base 1, a rotating block 2, a telescopic rod 3, a telescopic cylinder 4, a rotating rod 19, a base 13, a turntable 14, a measuring instrument 15, a sunshade 16, an adjusting rod 17, a torsion spring 20, a sunshade curtain 21, and a pull-out block 22. The three outer sides of the triangular base 1 are respectively bolted to the rotating blocks 2. Each rotating block 2 has a corresponding telescopic rod 3 rotatably connected to its lower end. Each telescopic rod 3 has a telescopic cylinder 4 fitted onto its lower outer side. Each telescopic rod 3 has several grooves on its lower outer side. The base 13 is fixedly connected to the top of the triangular base 1. The top of the base 13 has an inverted T-shaped groove. A turntable 14 slides on the top of the base 13. The bottom of the turntable 14 is slidably connected to the inverted T-shaped groove. The outer edge of the turntable 14 is rotatably connected to... A measuring instrument 15 is provided, and the measuring direction of the measuring instrument 15 can be adjusted to make construction measurements more accurate. An adjusting rod 17 is rotatably connected to the top front side of the measuring instrument 15. A sunshade 16 is fixedly mounted on the adjusting rod 17. Several insertion holes are opened on the side of the adjusting rod 17. Rotating rods 19 are rotatably connected to both sides inside the sunshade 16. Sunshade curtains 21 are wrapped around the outside of the rotating rods 19 on both sides inside the sunshade 16 to avoid the influence of light on the measurement when using the device. A torsion spring 20 is sleeved at both ends of each rotating rod 19. One end of the torsion spring 20 is fixedly connected to the inner wall of the sunshade 16, and the other end of the torsion spring 20 is fixedly connected to the rotating rod 19. Pull-out blocks 22 are fixedly connected to the outside of the sunshade curtains 21 on both sides.

[0024] like Figure 1 and Figure 5 As shown, it also includes a connecting block 6, an adjusting block 7, and a spiral spring 8. The top outer sides of the three telescopic cylinders 4 are all fixed with connecting blocks 6 by bolts. Adjusting blocks 7 are rotatably connected to the connecting blocks 6. The upper part of each adjusting block 7 is engaged in the groove of the telescopic rod 3, so that the height of the device can be adjusted according to the user's height, which has strong adaptability. A spiral spring 80 is provided between the lower part of each adjusting block 7 and one side of the telescopic cylinder 4.

[0025] like Figure 1 and Figure 6 As shown, it also includes a sleeve rod 9, a tension spring 10, a connecting plate 12, and a slider 11. The bottom of the triangular base 1 is fixedly connected to the sleeve rod 9 by bolts. The lower part of the sleeve rod 9 has grooves on both sides. The lower part of the sleeve rod 9 is slidably connected to the slider 11. The slider 11 is connected to the top of the inner side of the sleeve rod 9 by a tension spring 10. Three connecting plates 12 are provided on the outer side of the slider 11 in a circumferential direction. One end of each connecting plate 12 is rotatably connected to the slider 11, and the other end of each connecting plate 12 is rotatably connected to the inner side of the telescopic rod 3.

[0026] like Figure 4 As shown, it also includes a handle 23, which is fixedly connected to the rear top of the sun visor 16.

[0027] like Figure 1 As shown, it also includes a pressure block 5, and each telescopic cylinder 4 has a pressure block 5 fixedly connected to its lower outer side by bolts.

[0028] like Figure 3 As shown, it also includes a latch 18, which engages with the insertion hole on the side of the adjusting rod 17.

[0029] Before using the device, it should be placed on a level surface. When using the device, ensure it is in the extended state. If the device is in the retracted state, the user can pull down the slider 11 until it reaches the bottom of the sleeve rod 9. The tension spring 10 inside the sleeve rod 9 will change from a compressed state to its original state, and the connecting plates 12 will change from a vertical state to a horizontal state. This will push the corresponding telescopic rod 3 to move outwards in a circular motion along the rotating block 2, and the telescopic cylinder 4 will also extend outwards. If the ground is uneven and muddy, the user can step on the pressure plates to apply downward force, causing the lower tips of the telescopic cylinders 4 to embed themselves in the soil, thus securing the device and ensuring it remains stationary during use. The device can also be adjusted according to usage... The height of the user is adjusted by the relative height of the telescopic rod 3 and the telescopic cylinder 4. Since the lower part of the adjusting block 7 is equipped with a helical spring 8, the user only needs to press the lower part of the adjusting block 7 and squeeze the helical spring 8 downwards. At this time, the helical spring 8 is in a compressed state, and the middle part of the adjusting block 7 can rotate around the connecting block 6. The upper part of the adjusting block 7 is equipped with a protruding locking block, and the telescopic rod 3 is equipped with several grooves that can engage with the protruding locking block on the upper part of the adjusting block 7. The user only needs to slide the adjusting rod 17 up and down to adjust to a suitable height, then release the lower part of the adjusting block 7. The helical spring 8 changes from a compressed state to its original state, and the protruding locking block on the upper part of the adjusting block 7 engages with the groove on the outer side of the telescopic rod 3, thus achieving the purpose of adjusting the height of the device. The base 13 at the upper end of the triangular base 1... The top has an inverted T-shaped groove, and the base 13 has a turntable 14 on top. The bottom of the turntable 14 is slidably connected to the inverted T-shaped groove, allowing the turntable 14 to rotate above the base 13 to adjust the measuring direction of the measuring instrument 15. Simultaneously, the measuring instrument 15 is rotatably connected to the outer edge of the turntable 14. The measuring instrument 15 and the turntable 14 are rotatably connected, allowing for more precise measurements by rotating the measuring instrument 15. Once the user has adjusted the turntable 14 and measuring instrument 15 to a suitable angle, they can remove the latch 18 inside the adjusting rod 17, then pull the handle 23 to rotate the sun visor 16 counterclockwise to a suitable angle. Since the adjusting rod 17 has several holes, after the sun visor 16 is rotated to the appropriate shading angle, the user can then... The latch 18 is inserted into the corresponding hole to fix the sunshade 16. If the sunlight is still strong after the sunshade 16 is opened, affecting the measurement effect, the user can pull the pull-out blocks 22 on both sides of the sunshade 16. The rotating rods 19 on both sides inside the sunshade 16 are wrapped with sunshade curtains 21. By pulling the pull-out blocks 22 on both sides, the sunshade curtains 21 on both sides can be pulled out. Pulling the pull-out blocks 22 down will make the sunshade curtains 21 fully unfolded. At this time, the device will greatly reduce the influence of sunlight on the measurement results. After the measurement is completed, the pull-out blocks 22 on both sides can be pulled up, and the sunshade curtains 21 on both sides can be reset under the action of the torsion spring 20 and retracted back into the sides of the sunshade 16.

[0030] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
