Description

Technical Field

[0001] This utility model relates to the field of land surveying technology, specifically to an anti-tipping surveying platform used in land surveying operations. Background Technology

[0002] Land surveying is a method of collecting geographic information. It can provide basic data for urban planning, support land management and supervision, and also help to identify problems such as land degradation and soil erosion in a timely manner, thus protecting land resources.

[0003] In the process of land surveying, a surveying station is required. When the surveying station is working, it can survey the topography of the land, as well as the boundaries, area, and shape, which can help staff to understand the land information in a timely manner.

[0004] When the surveying station is used outdoors, it may tip over or over due to wind or uneven terrain, which will affect the land surveying process.

[0005] To overcome the above-mentioned defects, prior art 1 (Chinese patent application number CN202323265686.0, application date 2023-12-01) describes a land surveying platform. It has a sliding support rod slidably installed inside the legs. By adjusting the cooperation between the worm gear and the worm wheel, the sliding support rod can be adjusted to slide inside the legs. When encountering uneven road surfaces, the sliding support rod in different legs can be extended to different lengths to ensure the balance and stability of the main body.

[0006] However, during use, a single auxiliary support structure still cannot overcome the problem of tipping over, and the surveying station mentioned in the above application still lacks stability during use, causing unnecessary trouble for the land surveying process.

[0007] Therefore, we propose an anti-tipping surveying platform for land surveying operations to solve the problems mentioned above. Summary of the Invention

[0008] The purpose of this utility model is to provide an anti-tipping surveying platform for land surveying operations, so as to solve the problem mentioned in the background art that the stability is still insufficient during use, which brings unnecessary trouble to the land surveying process.

[0009] To achieve the above objectives, the present invention provides the following technical solution: an anti-tipping surveying platform for land surveying operations, comprising a platform panel, a lower connecting block fixedly connected to the lower surface of the platform panel, a connecting shaft rotatably arranged inside the lower connecting block, and a sleeve fixedly connected to the surface of the connecting shaft.

[0010] The tube sleeve is rotatably equipped with a sliding rod, and the tube sleeve is evenly distributed on the lower surface of the table panel. A long rod is fixedly connected to the lower surface of the table panel, and an inner rod is slidably arranged inside the long rod. A support rod is fixedly connected to the end of the inner rod. A pressure rod is slidably arranged inside the lower connecting block.

[0011] Preferably, the end of the pressure rod is fixedly connected to an outer plate, and the lower surface of the outer plate is provided with a slot, and the pressure rod passes through the interior of the lower connecting block.

[0012] Preferably, a column is fixedly connected to the inner wall of the lower block, and a connecting rod is sleeved on the surface of the column, and the side view of the connecting rod is an inverted "L" structure.

[0013] Preferably, the end of the connecting rod is inclined, and the end of the connecting rod is initially located inside the slot. A second spring is fixedly connected to the upper surface of the connecting rod, and the other side of the second spring is fixedly connected to the inner wall of the lower block.

[0014] Preferably, a first spring is fixedly connected to the surface of the outer plate, and the other side of the first spring is fixedly connected to the outer surface of the lower block, and the first spring is initially in a stretched state.

[0015] Preferably, a sleeve rod is rotatably disposed on the surface of the sleeve, and the other side of the sleeve rod is rotatably disposed on the surface of the inner rod.

[0016] Preferably, the surface of the inner rod is fixedly connected to a limiting block, and the limiting blocks are symmetrically distributed about the center of the inner rod. The inside of the long rod is provided with a limiting groove corresponding to the limiting block.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the anti-tipping surveying platform for land surveying operations adopts a novel structural design, the specific details of which are as follows:

[0018] This anti-tipping surveying platform for land surveying operations initially has the pressure rod not in contact with the connecting shaft. After rotating to open the sleeve and slide rod, the connecting rod can be pulled to move its end out of the slot. At this time, the outer plate and the pressure rod move towards the connecting shaft under the action of the first spring. Finally, the connecting shaft is held in place by the pressure rod. At this time, the connecting shaft, sleeve, and slide rod will not rotate during operation, ensuring stability and thus optimizing the anti-tipping effect.

[0019] Furthermore, initially, the end of the connecting rod is located inside the slot. At this time, the connecting rod remains stable under the action of the second spring and the column. After the pressure rod has worked, when it is necessary to return the pressure rod to its original position, the pressure rod can be pulled outward. When the end of the connecting rod and the slot are in the same vertical direction, the connecting rod rises under the action of the second spring. Finally, the connecting rod will re-enter the slot. At this time, the outer plate and the pressure rod are locked again, which facilitates the next use of the pressure rod.

[0020] This anti-tipping surveying platform used for land surveying operations works by having the inner rod descend inside the long rod via the sleeve rod during the rotation of the sleeve. This causes the support rod to be inserted into the soil, where it provides auxiliary support and optimizes the support effect.

[0021] (3) In the anti-tipping surveying platform used for land surveying operations, the limiting block will slide inside the limiting groove during the movement of the inner rod. The limiting block and the limiting groove limit the movement distance of the inner rod and ensure stability. Attached Figure Description

[0030] 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.

[0031] Example 1: By using the pressure rod 9, the connecting shaft 8 and the sleeve 6 will not rotate during operation, ensuring strong stability and good anti-tipping effect. Figures 1-5 As shown, it includes a tabletop 1, a lower connecting block 2 is fixedly connected to the lower surface of the tabletop 1, and a connecting shaft 8 is rotatably arranged inside the lower connecting block 2, and a sleeve 6 is fixedly connected to the surface of the connecting shaft 8.

[0032] The tube sleeve 6 is rotatably equipped with a sliding rod 7, and the tube sleeve 6 is evenly distributed on the lower surface of the table panel 1. A long rod 3 is fixedly connected to the lower surface of the table panel 1, and an inner rod 4 is slidably arranged inside the long rod 3. A support rod 5 is fixedly connected to the end of the inner rod 4. A pressure rod 9 is slidably arranged inside the lower connecting block 2.

[0033] The end of the pressure rod 9 is fixedly connected to the outer plate 10, and the lower surface of the outer plate 10 is provided with a slot 12. The pressure rod 9 passes through the interior of the lower connecting block 2. The inner wall of the lower connecting block 2 is fixedly connected to the column 14, and the surface of the column 14 is fitted with a connecting rod 13. The side of the connecting rod 13 is viewed as an inverted "L" structure. The surface of the outer plate 10 is fixedly connected to the first spring 11, and the other side of the first spring 11 is fixedly connected to the outer surface of the lower connecting block 2. The first spring 11 is initially in a stretched state.

[0034] Initially, the end of the connecting rod 13 is located inside the slot 12. At this time, the outer plate 10 and the pressure rod 9 are engaged with the lower connecting block 2 (the first spring 11 is stretched at this time). The pressure rod 9 is not in contact with the connecting shaft 8, so the connecting shaft 8, the sleeve 6, and the slide rod 7 can be unfolded normally. After the connecting shaft 8, the sleeve 6, and the slide rod 7 are unfolded, the connecting rod 13 can be pulled down. At this time, the connecting rod 13 will descend vertically under the action of the column 14. After the end of the connecting rod 13 moves out of the slot 12, the outer plate 10 and the pressure rod 9 move towards the connecting shaft 8 under the action of the first spring 11. Finally, the pressure rod 9 will press against the connecting shaft 8, so that the connecting shaft 8, the sleeve 6, and the slide rod 7 will not rotate on their own, ensuring the stability of the working of the connecting shaft 8, the sleeve 6, and the slide rod 7, and optimizing the anti-tipping effect.

[0035] Example 2: Unlike Example 1, the second spring 15 allows the connecting rod 13 to quickly return to the inside of the slot 12, preventing the connecting shaft 8 from being squeezed and allowing the connecting shaft 8, sleeve 6, and slide rod 7 to rotate normally, facilitating the recovery of the device. Figure 4 As shown:

[0036] The end of the connecting rod 13 is inclined, and the end of the connecting rod 13 is initially located inside the slot 12. The upper surface of the connecting rod 13 is fixedly connected to the second spring 15, and the other side of the second spring 15 is fixedly connected to the inner wall of the lower block 2.

[0037] When it is necessary to re-lock the outer plate 10, pull the outer plate 10 and the pressure rod 9 outward. At this time, the second spring 15 is in a stretched state. When the end of the connecting rod 13 is in the same vertical direction as the slot 12, the connecting rod 13 moves upward under the action of the column 14 and the second spring 15 and finally enters the interior of the slot 12. At this time, the outer plate 10 and the pressure rod 9 are locked with the lower connecting block 2 again and do not contact the connecting shaft 8. The device can then be rotated normally, which is convenient for subsequent use of the device.

[0038] Example 3: Unlike Example 2, the inner rod 4 and support rod 5 provide auxiliary support and stability, thus optimizing the anti-tipping effect. Figure 6 and Figure 7 As shown:

[0039] The sleeve 6 is rotatably provided with a sleeve rod 16, and the other side of the sleeve rod 16 is rotatably provided on the surface of the inner rod 4. The surface of the inner rod 4 is fixedly connected with a limiting block 17, and the limiting blocks 17 are symmetrically distributed about the center of the inner rod 4. The inside of the long rod 3 is provided with a limiting groove 18 corresponding to the limiting block 17.

[0040] During the rotation of the sleeve 6, the sleeve 6 will drive the inner rod 4 to descend inside the long rod 3 through the sleeve rod 16, and then the support rod 5 will also be inserted into the soil. At this time, the support rod 5 plays an auxiliary support role and optimizes the support effect. During the movement of the inner rod 4, the limiting block 17 will slide inside the limiting groove 18. At this time, the limiting block 17 and the limiting groove 18 limit the movement distance of the inner rod 4 and ensure stability.

[0041] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
