Description

Technical Field

[0001] This utility model relates to the field of measurement support technology, specifically a foldable portable social survey measurement support. Background Technology

[0002] With societal development, the demand for social surveys is increasing across various sectors. In numerous fields such as urban planning, land resource management, environmental monitoring, and transportation planning, precise measurement work is essential to obtain accurate data and provide a basis for decision-making and research. For example, urban planning requires measuring information such as land topography, building location, and height to rationally plan urban space.

[0003] While existing measuring stands offer features like foldability and portability, social surveys often require frequent adjustments to measurement point locations based on actual conditions. If the stand is inconvenient to move, researchers must spend extra time and effort disassembling, transporting, and reinstalling it, reducing work efficiency. Furthermore, if the stand is unstable after being moved, repeated adjustments and fixation are necessary, leading to interruptions in the measurement work. This not only wastes time but can also disrupt researchers' train of thought, affecting the continuity and focus of their work, and increasing operational costs. Therefore, we propose a foldable, portable social survey measuring stand. Utility Model Content

[0004] The purpose of this invention is to provide a foldable portable social survey measurement stand to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable portable social survey measurement stand, comprising:

[0006] Support legs and top plates installed on the top of the support legs;

[0007] A portable sliding assembly is placed on a support leg. The portable sliding assembly includes a lifting seat disposed on the support leg, a universal wheel connected to the lifting seat, a first rotating shaft rotatably connected to the side of the lifting seat away from the universal wheel, a torsion spring disposed on the first rotating shaft, a limit plate rotatably connected to the torsion spring, a groove being provided at the bottom of the limit plate, an extension rod disposed on the side of the support leg near the limit plate, and a locking rod connected to the extension rod.

[0008] A stabilizing component is placed at the bottom of the support leg. The stabilizing component includes a base disposed at the bottom of the support leg, a fixing rod connected to the base, and a rubber disc disposed at the bottom of the fixing rod.

[0009] Furthermore, a magnetic ring is provided at the bottom of the lifting seat, and the bottom of the lifting seat is magnetically connected to the top of the base.

[0010] The above technical solution involves setting up a magnetic ring. When the support needs to be moved, the magnetic ring enables the lifting seat to be magnetically connected to the base, thereby ensuring that the casters are in contact with the ground.

[0011] Furthermore, the support leg is provided with an adjustment component, which includes a lifting support plate. A sliding seat is slidably connected to the side of the support leg near the lifting support plate. The lifting support plate is fixedly connected to the sliding seat, and a limit hole is provided on the sliding seat.

[0012] The above technical solution allows for the adjustment of the height of the top plate by setting up an adjustment component, thereby adjusting the height of the measuring instrument to adapt to different terrain undulations.

[0013] Furthermore, the top of the lifting support plate is threaded with bolts on the side near the top plate, and the top plate and the lifting support plate are threaded together.

[0014] The above technical solution involves using bolts to connect and fix the top plate to the lifting support plate.

[0015] Furthermore, a limiting seat is fixedly connected to the top of the support leg near the lifting support plate.

[0016] The above technical solution is adopted: by setting a limiting seat, the sliding seat is limited to prevent it from falling off the supporting leg.

[0017] Furthermore, the support leg is provided with a folding assembly, the folding assembly includes a second rotating shaft, a connecting rod rotatably connected to the second rotating shaft, a telescopic rod slidably connected to the connecting rod, a third rotating shaft rotatably connected to the telescopic rod, a connecting seat provided on the third rotating shaft, a slot provided on the connecting seat, and the third rotating shaft rotatably connected in the slot.

[0018] The above technical solution allows the bracket to be folded up when not in use, significantly reducing its overall size.

[0019] Furthermore, the support leg is provided in three parts, and the connecting rod and the telescopic rod are both provided in three parts.

[0020] The above technical solution enables the three support legs to retract and fold synchronously.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, a portable sliding component allows staff to quickly move the measuring device from one point to another without spending considerable time disassembling, transporting, and reassembling it. This solves the problem of frequent adjustments to measuring point positions required in social surveys based on actual conditions. If the support is difficult to move, investigators must spend extra time and effort disassembling, transporting, and reinstalling it, reducing work efficiency. The stabilizing component design ensures the stable return of the moved support, preventing the need for repeated adjustments and fixation that could interrupt measurement work if the support is unstable after movement. This not only wastes time but can also disrupt the investigator's train of thought, affecting the continuity and focus of their work, and increasing work costs. Attached Figure Description

[0034] 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.

[0035] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a foldable portable social survey measurement stand, comprising:

[0036] Support leg 1, top plate 2 installed on top of support leg 1;

[0037] Portable sliding component 3 is placed on support leg 1. Portable sliding component 3 includes lifting seat 31 set on support leg 1. Universal wheel 32 is connected to lifting seat 31. First rotating shaft 33 is rotatably connected to the side of lifting seat 31 away from universal wheel 32. Torsion spring 34 is set on first rotating shaft 33. Limit plate 35 is rotatably connected to torsion spring 34. Groove 38 is opened at the bottom of limit plate 35. Extension rod 36 is set on the side of support leg 1 near limit plate 35. Locking rod 37 is connected to extension rod 36.

[0038] Stabilizing component 4 is placed at the bottom of support leg 1. Stabilizing component 4 includes a base 41 set at the bottom of support leg 1, a fixing rod 42 connected to the base 41, and a rubber disc 43 set at the bottom of the fixing rod 42.

[0039] Specifically, when it is necessary to change the measurement point, there is no need to disassemble the bracket. The bracket can be moved by using the casters 32. After moving to the designated measurement point, the lifting seat 31 is separated from the base 41, and the lifting seat 31 slides up on the support leg 1, thereby driving the limit plate 35 to rise. When the limit plate 35 touches the locking rod 37, the limit plate 35 will rotate downward by the torsion spring 34. After passing the locking rod 37, the limit plate 35 will automatically reset, and then the groove 38 will lock onto the locking rod 37 for limiting, thereby retracting the casters 32 and separating them from the ground. Then, the rubber disc 43 contacts the ground to increase friction.

[0040] Furthermore, such as Figure 2 As shown: The bottom of the lifting seat 31 is equipped with a magnetic ring, and the bottom of the lifting seat 31 is magnetically connected to the top of the base 41. When it needs to be moved, the lifting seat 31 is attracted to the top of the base 41 through the magnetic ring, so that the caster wheel 32 contacts the ground.

[0041] The above solutions also have drawbacks: due to varying measurement points and complex terrain, fixed-height supports cannot adapt to different measurement needs, such as... Figure 1 and Figure 3 As shown: An adjustment component 5 is provided on the support leg 1. The adjustment component 5 includes a lifting support plate 51. A sliding seat 52 is slidably connected to the side of the support leg 1 near the lifting support plate 51. The lifting support plate 51 and the sliding seat 52 are fixedly connected. A limit hole is provided on the sliding seat 52. A bolt 53 is threadedly connected to the top of the lifting support plate 51 near the top plate 2. The top plate 2 and the lifting support plate 51 are threadedly connected. The sliding seat 52 is slid on the support leg 1, thereby driving the lifting support plate 51 connected on the outside and the top plate 2 connected on the top to rise and fall. Then, the screw is threaded into the limit hole for fixed limit.

[0042] The above solutions also have the drawback that the stand cannot be folded, taking up a lot of space during transport, such as... Figure 1 and Figure 4 As shown: A folding assembly 6 is provided on the support leg 1. The folding assembly 6 includes a second rotating shaft 61, a connecting rod 62 rotatably connected to the second rotating shaft 61, a telescopic rod 63 slidably connected to the connecting rod 62, a third rotating shaft 66 rotatably connected to the telescopic rod 63, a connecting seat 64 provided on the third rotating shaft 66, and a slot 65 provided on the connecting seat 64. The third rotating shaft 66 is rotatably connected in the slot 65. There are three support legs 1, and three connecting rods 62 and three telescopic rods 63 are provided. The three support legs 1 can be slidably retracted into the connecting rod 62 by connecting the connecting seat 64 and the third rotating shaft 66. Then, the connecting rod 62 can be rotated by using the second rotating shaft 61, so that the three support legs 1 can be brought together and retracted.

[0043] Furthermore, such as Figure 3 As shown: A limiting seat 7 is fixedly connected to the top of the support leg 1 near the lifting support plate 51. By setting the limiting seat 7, the sliding seat 52 is limited to prevent it from falling off the support leg 1.

[0044] like Figures 1-4As shown: First, place the measuring instrument on top of the top plate 2. Slide the sliding seat 52 on the support leg 1, thereby driving the lifting support plate 51 connected to the outside and the top plate 2 connected to the top to rise and fall. Then, fix the screw threaded into the limiting hole for limiting, thereby adjusting the height of the measuring instrument according to the measurement requirements. When it is necessary to change the measuring point, there is no need to disassemble the bracket. The bracket can be moved by using the universal wheel 32. When it is moved to the designated measuring point, separate the lifting seat 31 from the base 41, slide the lifting seat 31 on the support leg 1 to rise, thereby driving the limiting plate 35 to rise. When the limiting plate 35... When it comes into contact with the locking rod 37, the limiting plate 35 will rotate downwards via the torsion spring 34. After passing the locking rod 37, the limiting plate 35 will automatically reset, and then the groove 38 will engage with the locking rod 37 to limit the movement, thereby retracting the caster wheel 32 and separating it from the ground. Then, the rubber disc 43 will contact the ground to increase friction. When folding and storing is required, the three support legs 1 can slide the telescopic rod 63 back into the connecting rod 62 via the connecting seat 64 and the third pivot 66. Then, the connecting rod 62 can be rotated using the second pivot 61, thereby causing the three support legs 1 to retract together.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
