Description

Technical Field

[0001] This utility model belongs to the field of engineering surveying and mapping technology, specifically, it relates to a positioning and adjustment device for a surveying instrument. Background Technology

[0002] In the field of surveying and mapping engineering, the precise positioning of the surveying instrument is crucial to ensuring the accuracy of measurement data. The positioning and adjustment device, as an important auxiliary device for the surveying instrument, directly affects surveying efficiency and accuracy due to its stability and ease of adjustment. Currently, most surveying instrument positioning and adjustment devices adopt a tripod structure, using three support legs to support the surveying instrument and adjust its height.

[0003] However, in actual use, it was found that when changing the location within the work site, the operator needs to lift the entire device and move it. Furthermore, surveying operations often require the carrying of other auxiliary tools, and the operator needs to move the support frame, surveying instrument, and tool bag at the same time. Carrying multiple items separately not only increases the burden of transportation.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To address the issue of operators needing to lift and move the entire device when changing its location within the work area, and the fact that surveying operations often require carrying other auxiliary tools, necessitating the simultaneous transport of the support frame, surveying instrument, and tool bag, which increases the burden of carrying multiple items, the basic concept of this utility model is as follows: A surveying instrument positioning and adjustment device includes a mounting plate and a support assembly disposed at the bottom of the mounting plate. The bottom of the mounting plate has three mounting slots. The support assembly includes three support legs and three ball joints. The three support legs are respectively rotatably engaged with the mounting slots at the bottom of the mounting plate through the three ball joints. Two of the support legs are connected to movable wheels, and the other is connected to a foot pedal. A hook, a support plate, and a strap are connected above the foot pedal. The hook, support plate, and strap are all connected to the support legs. The three support legs are provided with a synchronous deployment mechanism with locking function, and each support leg is provided with a telescopic structure at its end that can be independently adjusted in length.

[0006] In a preferred embodiment of the present invention, the synchronous deployment mechanism includes three second connecting rods, a connecting plate, and a baffle. One end of each of the three second connecting rods is hinged to one of the three supporting legs, and the other end is hinged to the connecting plate. A baffle is rotatably mounted on the connecting plate, and the baffle has three through slots adapted to the width of the second connecting rods.

[0007] In a preferred embodiment of the present invention, the telescopic structure includes a rotating ring, a threaded rod, and a first connecting rod. The rotating ring is rotatably mounted on the end of the support leg. The rotating ring has an internal thread, and the threaded rod is engaged in the rotating ring. The end of the threaded rod away from the rotating ring is connected to the first connecting rod, and the end of the first connecting rod is connected to a ball head.

[0008] In a preferred embodiment of this utility model, the movable wheel is installed on the side of the corresponding support leg, and the height of the movable wheel is higher than the lowest end of the plug.

[0009] In a preferred embodiment of this utility model, a knob is rotatably mounted on the bottom of the mounting plate, and a connector for connecting a surveying instrument is connected to the knob.

[0010] In a preferred embodiment of this utility model, the end of the support leg away from the mounting plate is provided with a pin, and the outer side of the end of the support leg near the rotating ring and the rotating ring are both provided with anti-slip textures.

[0011] Compared with the prior art, the present invention has the following advantages: This invention provides stable support when the device is laid flat by inserting the feet into contact with the ground. Stepping on the moving wheels and foot pedals enhances the embedding force of the feet. When the device is tilted, the moving wheels contact the ground and roll to move the device. The integrated hooks, support plates, and straps can securely carry tools and reduce the burden of transportation. The connecting plates and connecting rods, together with the baffle, can drive the three support legs to open, close, and lock synchronously, simplifying operation and ensuring stability. Furthermore, the length of each support leg can be adjusted independently, making it easy to quickly adapt to different terrains and accurately level the device.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0016] like Figures 1 to 5 As shown, a surveying instrument positioning and adjustment device includes a mounting plate 1 and a support assembly located at the bottom of the mounting plate 1. The bottom of the mounting plate 1 has three mounting slots 7. The support assembly includes three support legs 2 and three ball heads 8. The three support legs 2 are rotatably engaged with the mounting slots 7 at the bottom of the mounting plate 1 through the three ball heads 8. Two support legs 2 are connected to movable wheels 17, and the other is connected to a foot pedal 19. A hook 21, a support plate 20, and a strap 18 are connected above the foot pedal 19. The hook 21, the support plate 20, and the strap 18 are all connected to the support legs 2. A synchronous unfolding mechanism with a locking function is provided between the three support legs 2, and each support leg 2 has an independently adjustable telescopic structure at its end. In this configuration, the ball head 8 and the mounting groove 7 cooperate to allow the support legs 2 to rotate flexibly, facilitating the unfolding, storage, and angle adjustment of the device; the two support legs 2 with casters 17 can contact the ground for convenient movement when the device is tilted; stepping on the foot pedal 19 and casters 17 can enhance the fixing effect of the insert 16; the hook 21, support plate 20, and strap 18 can be used to hang and fix backpacks and other items; the synchronous unfolding mechanism realizes the linkage opening, closing, and locking of the support legs 2; and the telescopic structure can independently adjust the length of each support leg 2 to adapt to different terrains.

[0017] like Figures 1 to 5As shown, in a specific embodiment, the synchronous deployment mechanism includes three second connecting rods 9, a connecting plate 10, and a baffle 11. One end of each of the three second connecting rods 9 is hinged to one of the three support legs 2, and the other end is hinged to the connecting plate 10. The baffle 11 is rotatably mounted on the connecting plate 10, and the baffle 11 has three through slots 12 adapted to the width of the second connecting rods 9. In this configuration, the second connecting rods 9 link the support legs 2 with the connecting plate 10, so that the support legs 2 can be synchronously deployed or retracted as the connecting plate 10 moves. The baffle 11 rotates to align or offset the through slots 12 with the second connecting rods 9. When aligned, the restriction on the second connecting rods 9 is released; when offset, it abuts against the second connecting rods 9 to restrict their movement, thereby achieving the locking and unlocking of the support legs 2.

[0018] like Figures 1 to 5 As shown, the telescopic structure further includes a rotating ring 3, a threaded rod 5, and a first connecting rod 6. The rotating ring 3 is rotatably mounted on the end of the support leg 2. An internal thread 4 is formed inside the rotating ring 3, and the threaded rod 5 is engaged within it. The end of the threaded rod 5 furthest from the rotating ring 3 is connected to the first connecting rod 6, and the end of the first connecting rod 6 is connected to a ball head 8. In this configuration, the rotating ring 3 and the threaded rod 5 are engaged by the internal thread 4. When the rotating ring 3 is rotated, the threaded rod 5 can extend or retract axially, thereby moving the ball head 8 via the first connecting rod 6, thus adjusting the overall length of the support leg 2 to adapt to different terrain heights.

[0019] like Figures 1 to 5 As shown, furthermore, the movable wheel 17 is installed on the side of the corresponding support leg 2, and the height of the movable wheel 17 is higher than the lowest end of the plug 16. In this configuration, the movable wheel 17 is higher than the plug 16 to ensure that the plug 16 contacts the ground for stable support when the device is laid flat, and the movable wheel 17 does not contact the ground to avoid affecting the fixing effect. When the device is tilted, the movable wheel 17 can contact the ground and move the device by rolling, improving the convenience of handling.

[0020] like Figures 1 to 5 As shown, a knob 13 is rotatably mounted on the bottom of the mounting plate 1, and a connector 14 for connecting a surveying instrument is connected to the knob 13. In this configuration, the connector 14 is used to fix the surveying instrument, and the knob 13 can drive the connector 14 to rotate, thereby achieving the connection.

[0021] like Figures 1 to 5 As shown, furthermore, the end of the support leg 2 away from the mounting plate 1 is provided with a pin 16, and both the outer end of the support leg 2 near the rotating ring 3 and the rotating ring 3 are provided with anti-slip textures 15. In this configuration, the pin 16 can enhance the grip of the support leg 2 on the ground, and the anti-slip textures 15 increase the friction between the hand and the support leg 2 and the rotating ring 3, making it easier to apply force during rotation and preventing slippage.

[0022] The implementation principle of the mapping instrument positioning and adjustment device in this embodiment is as follows: The whole is based on the mounting plate 1 as the core load-bearing component. Its bottom is connected to the support assembly through three evenly distributed mounting grooves 7 that are adapted to the ball head 8. The support assembly consists of support legs 2 and ball heads 8. The cooperation between the ball head 8 and the mounting groove 7 allows the support legs 2 to rotate flexibly around the mounting plate 1, laying the foundation for the device to unfold, adjust angles and move. The synchronous unfolding mechanism realizes the linkage operation of the support legs 2. One end of the three second connecting rods 9 is respectively hinged to the three support legs 2, and the other end is hinged to the connecting plate 10. When the connecting plate 10 is moved, the second connecting rods 9 will drive the support legs 2 to open and close synchronously. After the support leg 2 is extended to a suitable angle, rotate the baffle 11 on the connecting plate 10 so that the through groove 12 on the baffle 11 is misaligned with the second connecting rod 9. At this time, the baffle 11 directly abuts against the second connecting rod 9, restricting its rotation and thus locking the support leg 2. If the baffle 11 is rotated until the through groove 12 is aligned with the second connecting rod 9, the second connecting rod 9 can pass through the through groove 12, and the baffle 11 no longer restricts it, so the support leg 2 can be stored. The telescopic structure at the end of each support leg 2 can be independently adjusted in length. A rotating ring 3 is rotatably installed at the end of the support leg 2. The rotating ring 3 meshes with the threaded rod 5. When the rotating ring 3 is rotated, the threaded rod 5 will extend or retract in the forward and reverse directions, thereby changing the support leg's rotation. The support legs 2 have an overall length, and the inserts 16 at the ends of the support legs 2 enhance ground grip. The anti-slip textures 15 on the support legs 2 and the rotating ring 3 facilitate anti-slip during operation. The lengths of the three support legs 2 can be adjusted to adapt to different terrains, ensuring that the mounting plate 1 is level. The three support legs 2 adopt a differentiated design. Two support legs 2 have movable wheels 17 installed on their sides, and the height of the movable wheels 17 is higher than the lowest end of the inserts 16. When the device is laid flat, the movable wheels 17 do not touch the ground, ensuring that the inserts 16 have a stable grip. When movement is required, tilting the device so that the two movable wheels 17 touch the ground allows for easy movement of the device. The other support leg 2 has a foot pedal 19, which can be used to step on the foot pedal or the movable wheel. 17. It can enhance the ground embedding force of the insert 16 and improve the fixed stability. The support leg 2 with foot pedal 19 also integrates hook 21, support plate 20 and strap 18. The hook 21 can directly hang backpacks, toolboxes and other items. The support plate 20 supports the suspended items and prevents them from shaking. The strap 18 can further tie and fix the suspended items to prevent them from falling. After the support leg 2 is stored, the three support legs 2 can be tied together by the strap 18 for easy carrying. The knob 13 at the bottom of the mounting plate 1 is connected to the connector 14. The knob 13 can drive the connector 14 to rotate. The connector 14 is directly connected to the bottom of the surveying instrument for fixation.
