Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping technology, specifically a multifunctional surveying and mapping platform. Background Technology

[0002] With social development, people's demand for surveying and mapping technology is constantly increasing. Surveying and mapping technology is widely used in fields such as construction, agriculture, environment, geological exploration, marine exploration, and aerospace. The use of multi-functional surveying and mapping platforms is indispensable in the surveying and mapping process. A multi-functional surveying and mapping platform is a multi-functional auxiliary tool designed for surveying engineers, geographic information system users, and mapmakers. It can provide support for surveying and mapping equipment and facilitate the drawing of surveyors. Existing multi-functional surveying and mapping platforms generally consist of a desktop and support legs. The support legs are generally fixed. In order to reduce the size and facilitate carrying, they often need to be disassembled when carrying. At the same time, the height of the desktop cannot be adjusted when using it, which affects the comfort and convenience of use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a multifunctional surveying platform. By adjusting the opening angle of the U-shaped legs and H-shaped legs, the height of the surveying table can be adjusted. At the same time, the legs can be folded, which makes it comfortable and convenient to use, and can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional surveying platform, including a surveying desktop and an adjustment unit;

[0005] Surveying tabletop: A silicone drawing pad is provided on the right side of its upper surface. Four connecting seats are provided on the lower surface of the surveying tabletop. The two connecting seats on the left are rotatably connected to a first rotating shaft, and the two connecting seats on the right are rotatably connected to a second rotating shaft. The first rotating shaft is fixedly connected to the upper end of the H-shaped support leg, and the second rotating shaft is fixedly connected to the upper end of the U-shaped support leg. The front side of the first rotating shaft and the rear side of the second rotating shaft are both provided with limiting handles.

[0006] Adjustment unit: Located on the front side of the lower surface of the surveying table, the limiting handle is designed to work in conjunction with the adjustment unit. By adjusting the opening angle of the U-shaped legs and H-shaped legs, the height of the surveying table can be adjusted, greatly improving the comfort of surveyors. In addition, the legs can be folded, improving the convenience of carrying.

[0007] Furthermore, the adjustment unit includes a positioning block, a lead screw seat, and a bidirectional lead screw. The lead screw seats are symmetrically arranged on the lower surface of the surveying table. A bidirectional lead screw is rotatably connected between the two lead screw seats through a bearing. Positioning blocks are threaded to both ends of the bidirectional lead screw. The positioning blocks are slidably connected to the dovetail grooves on the lower surface of the surveying table. The positioning blocks are respectively configured to cooperate with the adjacent lateral limiting handles to facilitate the positioning of the U-shaped support legs and the H-shaped support legs.

[0008] Furthermore, the adjustment unit also includes a worm gear seat, a worm, and a worm wheel. The worm gear seats are symmetrically arranged in the middle of the lower surface of the surveying table. The two worm gear seats are rotatably connected by a bearing. The worm wheel is located in the middle of the double-acting screw. The worm and the worm wheel are meshed together to facilitate the adjustment of the position of the limiting positioning block.

[0009] Furthermore, the adjustment unit also includes a handwheel, which is located at the front end of the worm gear for easy control of the worm gear's rotation.

[0010] Furthermore, the lower ends of both the H-shaped and U-shaped outriggers are rotatably connected to support feet via pins, increasing the contact area between the H-shaped and U-shaped outriggers and the ground.

[0011] Furthermore, the lower surface of each support foot is provided with a rubber pad to increase friction with the ground.

[0012] Furthermore, the lower surface of the silicone drawing pad is provided with an iron sheet, the lower surface of which is fixedly connected to the surveying table. The upper surface of the silicone drawing pad is provided with evenly distributed magnetic nails, which are magnetically attracted to the iron sheet to facilitate the fixation of the drawing paper.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This multifunctional surveying platform has the following advantages:

[0014] 1. When the surveying table height is too high and affects use, the handwheel can be rotated. The handwheel drives the worm gear to rotate, which in turn drives the double-ended lead screw to rotate. The double-ended lead screw drives the positioning block to slide along the long groove on the lower surface of the surveying table towards the center. After the positioning block moves, the downward force on the surveying table will cause the lower ends of the U-shaped and H-shaped legs to continue to move outward, thereby adjusting the height of the surveying table. The U-shaped leg drives the right-side limiting handle to rotate counterclockwise through the second pivot, contacting the right-side positioning block and limiting the further opening of the U-shaped leg. The H-shaped leg drives the left-side limiting handle to rotate clockwise through the first pivot, contacting the left-side positioning block and limiting the further opening of the H-shaped leg. This ensures the stability of the U-shaped and H-shaped legs in supporting the surveying table. During use, the position of the positioning block can be controlled by rotating the handwheel, and the opening angle of the U-shaped and H-shaped legs can be adjusted, thereby adjusting the height of the surveying table and greatly improving the comfort of surveyors.

[0015] 2. After use, the surveying table can be lifted up. First, fold the H-shaped legs, and then fold the U-shaped legs. The U-shaped legs have a clearance groove in the middle that corresponds to the H-shaped legs. The surveying table, U-shaped legs, and H-shaped legs can then be folded together. After surveying is finished, the legs can be folded to reduce the space occupied and greatly improve the convenience of carrying. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This embodiment provides a technical solution: a multi-functional surveying platform, including a surveying desktop 1 and an adjustment unit 7;

[0024] Surveying tabletop 1: A silicone drawing pad 9 is provided on the right side of its upper surface. Surveying equipment can be placed on the left side of the upper surface of the surveying tabletop 1, and drawing paper can be laid flat on the upper surface of the silicone drawing pad 9. The lower surface of the surveying tabletop 1 is provided with four connecting seats 2. The two connecting seats on the left are rotatably connected to a first rotating shaft 3, and the two connecting seats on the right are rotatably connected to a second rotating shaft 5. The first rotating shaft 3 is fixedly connected to the upper end of the H-shaped support leg 4, and the second rotating shaft 5 is fixedly connected to the upper end of the U-shaped support leg 6. The U-shaped support leg 6 and the H-shaped support leg 4 are arranged in a "V" shape, providing support for the surveying tabletop 1 through the second rotating shaft 5, the first rotating shaft 3, and the connecting seats 2. The front side of the pivot 3 and the rear side of the pivot 5 are both equipped with limiting handles 11. The lower ends of the H-type support leg 4 and the U-type support leg 6 are rotatably connected to the support foot 12 by a pin. The support foot 12 increases the contact area between the H-type support leg 4 and the U-type support leg 6 and the ground. The lower surface of the support foot 12 is equipped with a rubber pad 13, which increases the friction with the ground. The lower surface of the silicone drawing pad 9 is equipped with an iron sheet 8, which is fixedly connected to the surveying table 1. The upper surface of the silicone drawing pad 9 is equipped with evenly distributed magnetic nails 10, which are magnetically attracted to the iron sheet 8. The magnetic attraction between the magnetic nails 10 and the iron sheet 8 has a good fixing effect on the drawing paper.

[0025] Adjustment unit 7: Located on the front side of the lower surface of the surveying tabletop 1, the limiting handles 11 are all configured to cooperate with the adjustment unit 7. The adjustment unit 7 includes positioning blocks 71, lead screw seats 72, and bidirectional lead screws 73. The lead screw seats 72 are symmetrically arranged on the lower surface of the surveying tabletop 1. The bidirectional lead screws 73 are rotatably connected between the two lead screw seats 72 through bearings. The lead screw seats 72 provide rotational support for the bidirectional lead screws 73. Positioning blocks 71 are threaded to both ends of the bidirectional lead screws 73. The positioning blocks 71 are slidably connected to the dovetail grooves on the lower surface of the surveying tabletop 1. After the positioning blocks 71 move, the downward force on the surveying tabletop 1 will cause the lower ends of the U-shaped support legs 6 and H-shaped support legs 4 to continue to move outward, thereby realizing the adjustment of the height of the surveying tabletop 1. The U-shaped support leg 6 drives the right limiting handle 11 to rotate counterclockwise through the second pivot 5 to contact the right positioning block 71. The H-shaped support leg 4 drives the left limiting handle 71 through the first pivot 3 to rotate counterclockwise. The handle 11 rotates clockwise to contact the positioning block 71 on the left, thereby ensuring the stability of the U-shaped support leg 6 and the H-shaped support leg 4 in supporting the surveying table 1. The positioning block 71 is respectively set to cooperate with the horizontally adjacent limiting handle 11. The adjustment unit 7 also includes a worm seat 74, a worm 75 and a worm wheel 76. The worm seat 74 is symmetrically arranged in the middle of the lower surface of the surveying table 1. The two worm seats 74 are rotatably connected to the worm 75 through a bearing. The worm seat 74 provides rotational support for the worm 75. The worm wheel 76 is set in the middle of the double-acting screw 73. The worm 75 is meshed with the worm wheel 76. The worm 75 drives the double-acting screw 73 to rotate through the worm wheel 76. The double-acting screw 73 drives the positioning block 71 to slide along the long slide groove on the lower surface of the surveying table 1 towards the center. The adjustment unit 7 also includes a handwheel 77. The handwheel 77 is set at the front end of the worm 75. The handwheel 77 can be rotated, and the handwheel 77 drives the worm 75 to rotate.

[0026] The working principle of the multifunctional surveying platform provided by this utility model is as follows: In use, the U-shaped support leg 6 and H-shaped support leg 4 are arranged in a figure-eight shape, providing support for the surveying tabletop 1 through the second rotating shaft 5, the first rotating shaft 3, and the connecting seat 2. When the height of the surveying tabletop 1 is too high and affects use, the handwheel 77 can be rotated. The handwheel 77 drives the worm gear 75 to rotate, and the worm gear 75 drives the double-acting screw 73 to rotate through the worm wheel 76. The double-acting screw 73 drives the positioning block 71 to slide along the long sliding groove on the lower surface of the surveying tabletop 1 towards the center. After the positioning block 71 moves, the downward force on the surveying tabletop 1 will cause the lower ends of the U-shaped support leg 6 and H-shaped support leg 4 to continue to move outward, thereby achieving the adjustment of the height of the surveying tabletop 1. The U-shaped support leg 6 drives the right-side limiting handle 11 to rotate counterclockwise through the second rotating shaft 5, contacting the right-side positioning block 71 and limiting the U-shaped support leg 6. As the support leg 6 continues to open, the H-shaped support leg 4 rotates clockwise via the pivot 3, causing the left-side limiting handle 11 to contact the left-side positioning block 71, thus limiting the further opening of the H-shaped support leg 4 and ensuring the stability of the U-shaped support leg 6 and the H-shaped support leg 4 in supporting the surveying table 1. The surveying equipment can be placed on the left side of the upper surface of the surveying table 1, and the drawing paper can be laid flat on the upper surface of the silicone drawing pad 9 and then pressed down with the magnetic nail 10. The magnetic nail 10 and the iron sheet 8 magnetically attract each other, providing a good fixing effect for the drawing paper. After use, the surveying table 1 can be lifted up, and the H-shaped support leg 4 can be folded first, followed by the U-shaped support leg 6. The middle of the U-shaped support leg 6 has a clearance groove corresponding to the H-shaped support leg 4, so the surveying table 1, the U-shaped support leg 6 and the H-shaped support leg 4 can be folded together to reduce the space occupied by themselves.
