Description

Technical Field

[0001] This utility model relates to the field of medical device components technology, and in particular to a foldable fence for highway maintenance projects. Background Technology

[0002] During highway maintenance construction, in order to ensure the safety of the construction area and prevent unrelated vehicles and pedestrians from accidentally entering the work site and causing safety accidents, it is usually necessary to set up fences to isolate the construction area.

[0003] Existing highway maintenance fences are mostly fixed structures with large overall volume, occupying a lot of space during transportation, increasing transportation costs and difficulties. At the same time, due to differences in road width and construction scope, fences need to be able to flexibly adjust their layout, but traditional fences are difficult to adjust the angle flexibly and have poor adaptability. In addition, traditional fences are heavy, requiring a lot of manpower to move and deploy. Moreover, although some fences have pulleys at the bottom for easy movement, the pulleys lack effective storage and fixing structures, making them prone to sliding when stationary, affecting stability. Alternatively, the absence of pulleys makes movement inconvenient, making it difficult to balance ease of movement with stability when stationary.

[0004] This addresses the shortcomings of existing fences in terms of transportation convenience, angle adjustment flexibility, ease of movement, and static stability.

[0005] Therefore, this application provides a foldable fence for highway maintenance projects to meet the requirements. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a foldable fence for highway maintenance projects to solve the shortcomings of existing fences in terms of transportation convenience, angle adjustment flexibility, labor-saving movement and static stability.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A foldable fence for highway maintenance includes a fence body: a hollow rotating cylinder is provided on one side of the fence body, and a folding assembly is provided on the other side of the fence body. The folding assembly of another fence body is rotatably connected inside the hollow rotating cylinder. The folding assembly is internally continuous and is used to fold the fence. An adjustment assembly is rotatably connected inside the folding assembly and is used to adjust the folding angle of the fence and the bottom pulleys.

[0009] Optionally, the folding assembly includes a connecting shaft, one end of which is fixedly mounted on the side of the fence body, and the other end of which is fixedly connected to a first mounting block, the bottom of which is fixedly connected to a first adjusting rod.

[0010] Optionally, an annular baffle is provided inside the first adjusting rod, a first sliding groove is provided on the inner side of the annular baffle, and an adjusting plate is fixedly connected above the annular baffle.

[0011] Optionally, the adjusting plate and the first slide groove are each configured as several groups, and each group of the adjusting plate consists of two vertical baffles, with a second slide groove formed between the two vertical baffles, and the first slide groove and the second slide groove are connected.

[0012] Optionally, the number of connecting shafts is set to two, one above the other. The lower connecting shaft is fixedly connected to the second mounting block. The top of the second mounting block is fixedly connected to the bottom of the first adjusting rod. The bottom of the second mounting block is provided with a hollow base.

[0013] Optionally, the adjustment component includes an adjustment block, a second adjustment rod is fixedly connected to the bottom of the adjustment block, and a sliding plate is provided on the second adjustment rod. In the initial state, the sliding plate is located in the second slide groove and can slide inside the first slide groove and the second slide groove.

[0014] Optionally, a pulley is provided at the bottom of the second adjusting rod, and the pulley is located inside the hollow base.

[0015] Optionally, the pulley is a swivel wheel.

[0016] Optionally, the fence body is made of stainless steel.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] In the above solution, by setting up a folding component, the rotation of the adjusting block can drive the slide plate to rotate inside the first adjusting rod. Since the slide plate is initially located in the second sliding groove, it can drive the adjusting plate and the first adjusting rod to rotate as a whole, so that the two adjacent fence bodies can be folded by the rotation of the folding component. The operation is simple and convenient, which is beneficial to the storage and transportation of the fence.

[0019] With the adjustable components, when the fence is folded and transported to the work site and unfolded, pressing down on the adjusting block will cause the slide plate to slide down along the second and first slide tracks, allowing the bottom pulley to extend from the hollow base and contact the ground. Slightly rotating the adjusting block will cause the top of the slide plate to be abutted by the bottom of the annular baffle, ensuring that the pulley will not retract into the hollow base without continuous manual pressing. The fence can be moved and arranged by the pulley during work, reducing physical exertion. After moving to the appropriate position, the pulley can be retracted into the hollow base, enhancing the stability of the fence when stationary.

[0020] By closely cooperating with the folding and adjusting components, the folding component is internally continuous, and the adjusting component can slide and rotate flexibly within the folding component. This not only realizes the folding function of the fence, but also allows for adjustment of the folding angle and bottom pulleys, thus improving the practicality and flexibility of the fence in highway maintenance projects.

[0034] like Figures 1 to 4As shown, an embodiment of this utility model provides a foldable fence for highway maintenance projects, including a fence body 1. A hollow rotating cylinder 2 is provided on one side of the fence body 1, and a folding component 3 is provided on the other side of the fence body 1. The folding component 3 of another fence body 1 is rotatably connected inside the hollow rotating cylinder 2. The folding component 3 is internally open and is used to fold the fence. An adjustment component 4 is rotatably connected inside the folding component 3. The adjustment component 4 is used to adjust the folding angle of the fence and the bottom pulley 404. Through the cooperation of the folding component 3 and the adjustment component 4, the fence can not only be folded, but also the folding angle and the bottom pulley 404 can be adjusted, which increases the functionality and adaptability of the fence, can meet the requirements of fence angle and mobility in different maintenance scenarios, and improves the convenience of use.

[0035] like Figures 1 to 3 As shown, the folding assembly 3 includes a connecting shaft 301. One end of the connecting shaft 301 is fixedly installed on the side of the fence body 1, and the other end of the connecting shaft 301 is fixedly connected to a first mounting block 302. A first adjusting rod 303 is fixedly connected to the bottom of the first mounting block 302. An annular baffle 304 is provided inside the first adjusting rod 303. A first sliding groove 305 is opened on the inner side of the annular baffle 304. An adjusting plate 306 is fixedly connected above the annular baffle 304. The adjusting plate 306 and the first sliding groove 305 are both set in several groups. Each group of adjusting plates 306 consists of two vertical baffles 3061. A second sliding groove 3062 is formed between the two vertical baffles 3061. The groove 305 is connected to the second sliding groove 3062. The number of connecting shafts 301 is set to two, one above the other. The lower connecting shaft 301 is fixedly connected to the second mounting block 307. The top of the second mounting block 307 is fixedly connected to the bottom of the first adjusting rod 303. The bottom of the second mounting block 307 is provided with a hollow base 308. The first sliding groove 305 on the annular baffle 304 inside the first adjusting rod 303 is connected to the second sliding groove 3062 formed by the adjusting plate 306, which provides a track for the sliding of the adjusting component 4, so that the adjustment of the fence folding angle can be accurately realized. Different folding angles can be stably locked through the cooperation of the sliding groove to meet diverse layout needs.

[0036] like Figure 4As shown, the adjustment component 4 includes an adjustment block 401, with a second adjustment rod 402 fixedly connected to the bottom of the adjustment block 401. A sliding plate 403 is provided on the second adjustment rod 402. In its initial state, the sliding plate 403 is located within the second slide groove 3062 and can slide within the first slide groove 305 and the second slide groove 3062. A pulley 404 is provided at the bottom of the second adjustment rod 402 and is located inside the hollow base 308. The pulley 403 is a universal wheel. The fence body 1 is made of stainless steel. The adjustment is achieved through the sliding plate 403 and the vertical baffle 3062. The combination of 61 improves the flexibility of the folding angle, making it easier to transport and arrange. The pulley 404 at the bottom of the second adjusting rod 402 is located inside the hollow base 308. When it is necessary to move the fence, the pulley 404 can be extended through the adjusting component 4, and the fence can be easily moved by the rolling property of the pulley 404, saving manpower. When it is not necessary to move, the pulley 404 can be retracted into the hollow base 308 and supported by the hollow base 308 to avoid wear and tear on the pulley 404, while enhancing the stability of the fence and adapting to different usage conditions.

[0037] The working principle of the technical solution provided by this utility model is as follows:

[0038] This invention uses the rotating adjusting block 401 to drive the sliding plate 403 to rotate inside the first adjusting rod 303. Since the sliding plate 403 is initially located inside the second sliding groove 3062, it drives the adjusting plate 306 and the first adjusting rod 303 to rotate as a whole. This allows two adjacent fence bodies 1 to complete the folding operation through the rotation of the first adjusting rod 303. The folding angle can be adjusted by the rotation angle of the adjusting block 401. It has strong applicability and is easy to operate.

[0039] Furthermore, when transporting the fence body 1 folded to the work site, first rotate the adjusting block 401 in reverse to unfold and arrange the fence body 1. Then press the adjusting block 401 down. Under the pressing action, the sliding plate 403 slides down along the second sliding groove 3062 and the first sliding groove 305 until the sliding plate 403 slides out of the first sliding groove 305 and the bottom pulley 404 extends out of the hollow base 308 and contacts the ground. Then rotate the adjusting block 401 slightly so that the top of the sliding plate 403 is abutted by the bottom of the annular baffle 304. Stop pressing the adjusting block 401. The annular baffle 304 replaces manual pressing to ensure that the pulley 404 will not retract into the hollow base 308, saving physical strength. During work, the fence body 1 is moved and arranged by the pulley 404, further saving manual labor. After the arrangement is completed, the adjusting block 401 can be restored so that the pulley 404 retracts into the hollow base 308, and the hollow base 308 contacts the ground, increasing the static stability.
