[0027] 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 scope of protection of the present utility model. Embodiment 1

[0028] In the existing design, most of the support devices on the market are fixed-size structures or use permanent connection methods such as welding to adjust the length, which is difficult to adapt to the support needs of different space sizes. In actual construction, if a complex and ever-changing working environment is encountered, support equipment needs to be frequently replaced or customized, resulting in low construction efficiency and a significant increase in costs. Furthermore, although some support devices have adjustment functions, the adjustment process relies on complex mechanical structures or professional tools, which are cumbersome and time-consuming to operate, and cannot meet the needs of rapid construction. In terms of combined use, this problem is obviously a real and difficult problem to solve. Therefore, in order to solve this technical problem, a coarse adjustment mechanism 3 and a fine adjustment mechanism 4 are added to this application.

[0029] Furthermore:

[0030] like Figure 1 As shown:

[0031] Based on the above: a support device includes a coarse adjustment mechanism 3;

[0032] The coarse adjustment mechanism 3 includes an inner support rod 35 and an outer support rod 36, and the inner support rod 35 slides on the inner surface of the outer support rod 36.

[0033] In this implementation plan, the user can pull the inner support rod 35 to slide it inside the outer support rod 36 according to the actual support requirements, thereby changing the total length of the entire coarse adjustment mechanism 3. By sliding the inner support rod 35 and the outer support rod 36, the device can adapt to the support requirements of different spans, thus improving its versatility.

[0034] Furthermore:

[0035] like Figure 1 As shown:

[0036] In an optional embodiment, the surfaces of the inner support rod 35 and the outer support rod 36 are each provided with a plurality of first mounting holes 37, and the surface of the outer support rod 36 is provided with a first locking mechanism 38, which fixes the inner support rod 35 and the outer support rod 36 through the first mounting holes 37.

[0037] In this implementation scheme: when the inner support rod 35 and the outer support rod 36 are adjusted to the appropriate length, the first mounting holes 37 on the inner support rod 35 and the outer support rod 36 will be aligned. At this time, the first locking mechanism 38 passes through the aligned first mounting holes 37 to lock the inner support rod 35 and the outer support rod 36 together, forming a stable support structure. Furthermore, the design of the first mounting holes 37 and the first locking mechanism 38 makes the fixing operation of the inner support rod 35 and the outer support rod 36 simple and quick, reducing construction time.

[0038] It should be noted that the first locking mechanism 38 includes pins and bolts, and each bolt must be used with at least three pins. A set of spare bolts is placed at the end of the outer support rod 36 away from the right positioning block 32.

[0039] Furthermore:

[0040] like Figures 1 to 3 As shown:

[0041] In an optional embodiment, a steel plate 1 is provided at the end of the inner support rod 35 away from the outer support rod 36 and at the end of the outer support rod 36 away from the inner support rod 35. Side plates 2 are symmetrically fixedly connected to the surface of the steel plate 1. A plurality of partitions 21 are fixedly connected to the surface of the side plates 2. A left positioning block 31 and a right positioning block 32 are slidably connected to the surface of the side plates 2. A left fixing plate 33 is fixedly connected to the end of the left positioning block 31 away from the side plate 2. A right fixing plate 34 is fixedly connected to the end of the right positioning block 32 away from the side plate 2. The end of the left fixing plate 33 away from the left positioning block 31 is fixedly connected to the inner support rod 35. An outer support rod 36 is provided at the end of the right fixing plate 34 away from the right positioning block 32.

[0042] In this embodiment: steel plate 1 and side plate 2 constitute the connection interface between the support device and the support surface. Steel plate 1 directly contacts the support surface, uniformly transmitting the support force to the support surface and avoiding local stress concentration. Partition plates 21 are fixed between the side plates 2, which enhances the rigidity and stability of the side plates 2. At the same time, partition plates 21 act as multiple lateral supports, dividing the side plates 2 into multiple small areas that cooperate with the left positioning block 31 and the right positioning block 32. The left positioning block 31 is placed between the left partition plates 21, and the right positioning block 32 is placed between the right partition plates 21, forming an embedded installation structure. This design allows the inner support rod 35 and the outer support rod 36 to adjust their height within a certain range to adapt to different support scenarios.

[0043] Furthermore:

[0044] like Figure 2 As shown:

[0045] In an optional embodiment, the surface of the side plate 2 is provided with a plurality of second mounting holes 39, and the surfaces of the left positioning block 31 and the right positioning block 32 are provided with a second locking mechanism 310. The left positioning block 31 and the right positioning block 32 are both fixedly connected to the side plate 2 through the second locking mechanism 310.

[0046] In this embodiment: after the left positioning block 31 and the right positioning block 32 are positioned, the construction personnel pass the second locking mechanism 310 through the side plate 2 and the positioning block in sequence. The pre-tightening force generated by tightening the nut fixes the positioning block to the surface of the side plate 2. This fixing method ensures the stability of the left positioning block 31 and the right positioning block 32 during use and avoids equipment damage due to loosening, which would prevent support operations from being carried out.

[0047] It should be noted that the second locking mechanism 310 includes a pin and a bolt.

[0048] Furthermore:

[0049] like Figure 2 As shown:

[0050] In an optional embodiment, the inner support rod 35 is symmetrically fixedly connected with reinforcing ribs 311, and the reinforcing ribs 311 are fixedly connected to the left fixing plate 33.

[0051] In this embodiment, the reinforcing ribs 311 are symmetrically welded in a triangular shape to the surface of the inner support rod 35 and connected to the left fixing plate 33 to form a stable mechanical support structure. This significantly enhances the structural strength of the inner support rod 35, enabling the device to withstand greater loads and making it suitable for high-stress environments. It also prevents the inner support rod 35 from becoming deformed due to stress, thus ensuring the safety and reliability of the support structure.

[0052] Furthermore:

[0053] like Figure 1 As shown:

[0054] In an optional embodiment, four sets of third locking mechanisms 312 are symmetrically arranged on the surfaces of the left positioning block 31 and the right positioning block 32, and compression springs 313 are sleeved on the surfaces of the third locking mechanisms 312.

[0055] In this embodiment: the third locking mechanism 312 passes through the left positioning block 31 and the right positioning block 32. The compression spring 313 is sleeved on the outside of the bolt and pre-compressed. When the device is subjected to external impact or vibration, the spring absorbs energy through elastic deformation and buffers the rigid collision between the components. At the same time, the elastic force of the spring continues to act on the positioning block, automatically compensating for the small displacement caused by vibration and keeping the components tightly connected. This structure effectively reduces the impact of vibration on the device, reduces the risk of component loosening and wear, extends the equipment life, and the adaptive compensation function ensures that the coarse adjustment mechanism 3 remains stable under dynamic working conditions.

[0056] It should be noted that the third locking mechanism 312 includes a pin and a bolt.

[0057] Furthermore:

[0058] like Figure 1 As shown:

[0059] In an optional embodiment, a fine-tuning mechanism 4 is also provided on the surface of the right fixing plate 34;

[0060] The fine-tuning mechanism 4 includes a rotating column 41 rotatably connected to the surface of the right fixed plate 34. A threaded rod 42 is fixedly connected to one end of the rotating column 41 away from the right fixed plate 34. The threaded rod 42 is threadedly connected to the outer support rod 36.

[0061] In this embodiment, the rotating column 41 can rotate freely on the surface of the right fixed plate 34, and the threaded rod 42 at its end is threadedly connected to the outer support rod 36. By rotating the rotating column 41, the rotational motion is converted into a small axial displacement of the outer support rod 36 using the thread transmission principle, so as to achieve fine adjustment of the length of the device and make up for the insufficient accuracy of the coarse adjustment mechanism 3.

[0062] Furthermore:

[0063] like Figure 1 As shown:

[0064] In an optional embodiment, three sets of connecting rods 43 are uniformly fixedly connected to the surface of the rotating column 41.

[0065] In this embodiment, the three sets of connecting rods 43 on the surface of the rotating column 41 are evenly distributed at 120 degrees to form a lever structure. The operator can apply force by holding the connecting rods 43, which significantly reduces the difficulty of fine-tuning, reduces the intensity of manual labor, and improves the adjustment efficiency.

[0066] Furthermore:

[0067] like Figure 4 As shown:

[0068] In an optional embodiment, a first locking block 5 is fixedly connected to one end of the steel plate 1, and a second locking block 51 that cooperates with the first locking block 5 is fixedly connected to the other end of the steel plate 1 away from the first locking block 5.

[0069] In this embodiment: when steel plates 1 need to be spliced, the first card block 5 is inserted into the slot of the corresponding second card block 51, and a quick connection is achieved by mechanical interlocking. The tool-free splicing design greatly shortens the construction time, supports rapid on-site assembly, and the modular splicing method can flexibly expand the support length according to project needs.

[0070] Furthermore:

[0071] like Figure 3 and Figure 4 As shown:

[0072] In an optional embodiment, the surface of the steel plate 1 is symmetrically fixedly connected with a first connecting ear 6 and a second connecting ear 61, and the bottom end of the steel plate 1 is provided with a bevel 7.

[0073] In this embodiment: the first connecting ear 6 and the second connecting ear 61 are symmetrically distributed on the surface of the steel plate 1. The reserved bolt holes allow the two steel plates 1 to be connected by bolts, ropes, chains and other connecting parts when it is necessary to splice the steel plates 1. The diversified connection methods enhance the versatility and flexibility of the device and adapt to different engineering environments. The inclined surface 7 at the bottom of the steel plate 1 plays a guiding role during installation, reducing the resistance of insertion into the ground or foundation structure and improving construction efficiency.

[0074] Working principle: First, according to the actual support requirements, the left positioning block 31 and the right positioning block 32 are embedded into the corresponding areas divided by the partition plate 21 on the side plate 2. The second locking mechanism 310 passes through the second mounting hole 39 of the side plate 2 and is tightened to the left positioning block 31 and the right positioning block 32 to fix their positions. According to the support space size, the construction personnel push and pull the inner support rod 35 or the outer support rod 36, so that the inner support rod 35 slides in the outer support rod 36, quickly adjusting the overall length of the device to a roughly suitable size. After the rough adjustment is completed, ensure that the first mounting hole 37 on the surface of the inner support rod 35 and the outer support rod 36 is aligned, and then the first locking mechanism 38 is passed through the corresponding hole and tightened to realize the internal support. For fixing the positions of strut 35 and outer support rod 36, if the support dimension accuracy is high, the connecting rod 43 on the surface of the rotating column 41 is held, and the rotating column 41 is rotated, which drives the threaded rod 42 and the outer support rod 36 to achieve fine adjustment of the device length until the required size is reached. When it is necessary to extend the support length, the first locking block 5 of one steel plate 1 is inserted into the second locking block 51 slot of another steel plate 1, and the splicing is quickly completed by mechanical interlocking, so as to achieve flexible expansion of the support range. At this time, the first connecting ear 6 and the second connecting ear 61 on the surface of the steel plate 1 are connected to the first connecting ear 6 and the second connecting ear 61 on the surface of another set of steel plates 1 through bolts, ropes, chains and other connecting parts.

[0075] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
