Description

Technical Field

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

[0002] "Highway maintenance" refers to the upkeep and maintenance of highways. Upkeep focuses on the entire process of maintenance from the time a highway is built and opened to traffic, while maintenance focuses on repairing damaged parts. Fences are needed in the process of highway maintenance.

[0003] A foldable fence for highway maintenance engineering, authorized under publication number CN214885419U, includes a fence body and several legs mounted on the fence body. Both ends of the fence body are equipped with vertically arranged limiting cylinders, one of which is positioned above the other, and a rotating rod is inserted into one of the limiting cylinders. When the legs of the fence body are supported on the ground, the two limiting cylinders at opposite ends of two adjacent fence bodies will be coaxially aligned, and the rotating rod will be inserted into the two limiting cylinders, connecting the two fence bodies. The limiting cylinders can rotate around the axis of the rotating rod, allowing adjacent fence bodies to be combined at different angles, improving the applicability of the fence body. Furthermore, adjacent fence bodies can be folded together, facilitating fence transportation. This application facilitates the transportation of fences.

[0004] Regarding the aforementioned technologies, the existing fences have the following drawbacks: they can only be extended or shortened along a straight line during use, but are inconvenient for some road sections that require curved enclosure. Therefore, this utility model provides a foldable fence for highway maintenance projects. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example 1: Reference Figure 1-4The foldable fence for highway maintenance projects shown includes a pair of support rods 1. The support rods 1 support the entire fence structure and ensure that the fence can stand stably in the highway maintenance area. The side of the support rods 1 is fixedly connected to a fixing rod 2, which connects the support rods 1 and other components and provides support for the overall connection of the fence. A groove 9 is provided on the inner side of the fixing rod 2, providing space for the sliding of the connecting cylinder 3, allowing the connecting cylinder 3 to slide on its inner wall. The connecting cylinder 3 is slidably connected to the inner wall of the groove 9, enabling the fence to slide within the groove 9 and realize the telescopic function of the fence, facilitating the folding and unfolding of the fence. A pair of connecting cylinders 3 are hinged together, allowing the two connecting cylinders 3 to rotate relative to each other, further facilitating the folding operation of the fence. A connecting assembly is provided on the outer side of the pair of connecting cylinders 3; the connecting assembly includes a connecting frame 4 located on the outer side of the connecting cylinder 3, which is used to enhance the connection stability between the pair of connecting cylinders 3 and prevent the connecting cylinders 3 from separating during use. A slot 14 adapted to the connecting frame 4 is provided on the outer side of the connecting cylinder 3, which is used to accurately install the connecting frame 4 and ensure the accurate connection position between the connecting frame 4 and the connecting cylinder 3. A connecting block 5 is fixedly connected to the outer side of the connecting frame 4, and the connecting block 5 provides a connection for the bolt 6. The installation position facilitates the fixing of the connecting frame 4 and the connecting cylinder 3 with bolts 6. Bolts 6 are provided on the outer side of the connecting block 5 to tightly connect the connecting block 5 and the connecting cylinder 3, enhancing the firmness of the connection between the connecting frame 4 and the connecting cylinder 3. Threaded holes 15 that match the bolts 6 are opened on the outer side of both the connecting block 5 and the connecting cylinder 3. The threaded holes 15 cooperate with the bolts 6 to achieve the fastening installation of the bolts 6. An extension rod 18 is slidably connected to the inner wall side of the connecting cylinder 3. The extension rod 18 can slide inside the connecting cylinder 3 to further increase the length of the fence to adapt to different sizes of highway maintenance areas. A T-shaped block 12 is fixedly connected to the outer side of the extension rod 18. The T-shaped block 12 cooperates with the T-shaped groove 11 to play a guiding and limiting role. The inner wall side of the groove 9 is provided with a T-shaped groove 11 that matches the T-shaped block 12. The T-shaped groove 11 ensures that the extension rod 18 will not disengage from the groove 9 during sliding, making the sliding of the extension rod 18 more stable.

[0023] Example 2: Reference Figure 1-4Based on the same concept as in Embodiment 1 above, this embodiment further proposes that a slot 13 is provided on the inner wall side of the groove 9, which provides rotation space for the rotating rod 16. The rotating rod 16 is rotatably connected to the inner wall side of the groove 9, and the rotating rod 1 passes through the support rod 1, serving to connect and transmit rotation. A rotating block 17 is fixedly connected to one end of the rotating rod 16, which allows the user to manually operate the rotating rod 16 to rotate. A screw 8 is fixedly connected to the end of the rotating rod 16 away from the rotating block 17. A screw hole adapted to the screw 8 is provided on the inner side of the extension rod 18. When the rotating rod 16 rotates, the screw 8 rotates accordingly. Through the cooperation with the screw hole on the inner side of the extension rod 18, the extension rod 18 can be extended and retracted to adjust the overall length or position. A guardrail 7 is fixedly connected to the bottom of the fixed rod 2, which serves a protective function to prevent people or objects from falling accidentally. A base plate 10 is fixedly connected to the bottom end of the support rod 1, which increases the contact area with the ground and improves the stability of the entire device.

[0024] The working principle of this utility model is as follows: Dragging the rotating block 17 drives the rotating rod 16 and the screw 8 to rotate. The screw 8 drives the extension rod 18 to move. The extension rod 18 slides along the connecting cylinder 3, thereby adjusting the distance between the pair of support rods 1. The length of the fence can be increased or decreased according to actual needs. Unscrewing the bolt 6 releases the limit on the connecting block 5. Dragging the support rod 1, the fixing rod 2, and the connecting cylinder 3 deflects the fence. The included angle between the pair of connecting cylinders 3 can be adjusted according to actual needs, and the site can be enclosed in an arc shape.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
