Technical Field

[0001] This utility model relates to the field of construction fence technology, specifically a highway construction fence fixing frame. Background Technology

[0002] Highway construction fencing is mainly used to isolate construction areas and ensure the safety of construction workers, passing vehicles, and pedestrians. It is typically made of metal or plastic and features high strength, corrosion resistance, and ease of installation. Highway construction sites are usually of a certain length, while the fencing itself is of limited length; therefore, mounting frames are needed to assemble adjacent highway construction fencing sections together.

[0003] Most existing fixed frames and highway construction fences are assembled using screws and tools with repeated turning. This method is cumbersome and hinders the quick assembly and disassembly of the fixed frame and fence, thus affecting work efficiency. Furthermore, most existing fixed frames have fixed fence dimensions, making it inconvenient to install fences of different sizes, which limits their use. Therefore, we propose a new type of highway construction fence fixed frame. Summary of the Invention

[0004] The purpose of this utility model is to provide a highway construction fence fixing frame to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

Each of the two sets of connecting grooves is provided with a liftable lifting support plate. The top of the lifting support plate is connected to the connecting groove with a fence frame. The fence frame is provided with multiple sets of fence rods. The top wall of the fence frame near the connecting groove is provided with a locking groove. The top of the fixing frame body is provided with a disassembly and assembly component for fixing the locking groove.

[0007] Ear plates are installed at the bottom of both the front and rear side walls of the fixed frame. Each set of ear plates is vertically threaded with an adjusting screw, and a grounding cone is installed at the bottom of the adjusting screw.

[0008] Furthermore: a long screw is vertically installed in the connecting groove, the lifting support plate is slidably connected to the long screw, and a locking nut is threaded onto the long screw, with the top of the locking nut fitting against the bottom of the lifting support plate.

[0009] Furthermore: The disassembly and assembly components include a T-shaped plate, within which two sets of vertical sliding rods are vertically slidably connected, and the bottom of each set of vertical sliding rods is equipped with a locking block that matches the locking groove.

[0010] Furthermore: the top wall of the fixed frame has two sets of through ports for locking blocks, and the through ports are connected to the connecting groove. A compression spring is sleeved on the outside of the vertical slide rod, and the compression spring is located between the locking block and the T-shaped plate.

[0011] Furthermore, the inner wall of the connecting groove is embedded with corrugated protrusions, and the outer wall of the grounding cone is coated with an anti-corrosion layer.

[0012] Furthermore: a pull ring is installed at the end of the vertical slide bar away from the locking block, and the handle end of the pull ring is covered with an anti-slip rubber sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes the sliding of the vertical slide bar on the disassembly and assembly component and the elasticity of the compression spring to allow the locking block to pass through the opening and connect with the locking groove on the fence frame. This enables quick assembly and disassembly of the fixing frame and the highway construction fence, replacing the traditional method of using screws and tools for fixing, and effectively improving work efficiency. Through the sliding connection between the lifting support plate and the long screw and the threaded connection between the locking nut and the long bolt, the distance between the lifting support plate and the connecting groove can be adjusted. The fixing frame is suitable for the installation of highway construction fences of different sizes, with minimal limitations in its use. Attached Figure Description

[0019] 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. Example

[0020] Please see Figure 1-3 This utility model provides a technical solution: a highway construction fence fixing frame, including a fixing frame body 1. Connecting grooves 9 are provided on both sides of the inner cavity of the fixing frame body 1. Each of the two sets of connecting grooves 9 contains a liftable lifting support plate 5. A fence frame 2 is connected between the top of the lifting support plate 5 and the connecting groove 9. Multiple fence rods 3 are provided inside the fence frame 2. A locking groove is provided on the top wall of the fence frame 2 near the connecting groove 9. A disassembly and assembly component 4 for fixing the locking groove is provided on the top of the fixing frame body 1. The fence frame 2 and the multiple sets of fence rods 3 form a highway construction fence. In use, the fixing frame body 1 needs to be placed on the working ground. The dimensions of the fence frame 2 are measured to adjust the dimensions between the lifting support plate 5 and the connecting groove 9, ensuring that the fence frame 2 can be installed in the connecting groove 9. The fixing frame body 1 is suitable for installing highway construction fences of different sizes, with minimal limitations. When the fence frame 2 is connected to the connecting groove 9, the position of the fence frame 2 can be fixed through the disassembly and assembly component, replacing the traditional method of using screws and tools for fixing, effectively improving work efficiency.

[0021] Ear plates 6 are installed at the bottom of the front and rear side walls of the fixed frame 1. Each set of ear plates 6 is vertically threaded with an adjusting screw 7, and a grounding cone 8 is installed at the bottom of the adjusting screw 7. The ear plates 6 and the fixed frame 1 are an integral structure. By rotating the adjusting screw 7, the grounding cone 8 can be rotated and moved down, so that it can be connected to the ground, thereby reinforcing the position of the fixed frame 1.

[0022] Preferably, a long screw 11 is vertically installed in the connecting groove 9, and the lifting support plate 5 is slidably connected to the long screw 11. A locking nut 12 is also threaded onto the long screw 11, and the top of the locking nut 12 is attached to the bottom of the lifting support plate 5. By sliding the lifting support plate 5 and the long screw 11, the distance between the lifting support plate 5 and the connecting groove 9 can be adjusted. After determining its position, the locking nut 12 is rotated to make it fit against the bottom of the lifting support plate 5, thereby fixing the position of the lifting support plate 5.

[0023] Preferably, the disassembly component 4 includes a T-shaped plate 400, with two sets of vertical sliding rods 401 vertically slidably connected inside the T-shaped plate 400. The bottom of each set of vertical sliding rods 401 is equipped with a locking block 402 that matches the locking groove. The vertical sliding rods 401 and the locking blocks 402 are fixedly connected, and the T-shaped plate 400 and the fixed frame 1 are integrated.

[0024] Preferably, the top wall of the fixed frame 1 has two sets of through ports 10 for locking blocks 402, and the through ports 10 are connected to the connecting groove 9. A compression spring 403 is sleeved on the outside of the vertical slide rod 401, and the compression spring 403 is located between the locking block 402 and the T-shaped plate 400. The top wall of the fence frame 2 is pre-cut with locking grooves that are compatible with the locking blocks 402. During the connection between the fence frame 2 and the connecting groove 9, the vertical slide rod 401 is pulled up, at which time the compression spring 403 is compressed, and the locking block 402 is locked. 2. After passing through the port 10, it is located at the top of the fixed frame 1. When the fence frame 2 and the connecting groove 9 are installed, the locking groove opened on the top wall of the fence frame 2 is aligned with the port 10. When the vertical slide rod 401 is released, the compressed spring 403 will automatically return to its original position, which will drive the locking block 402 to move down and connect with the locking groove, thus fixing the position of the fence frame 2. When disassembling, the vertical slide rod 401 is pulled up, so that the locking block 402 is disengaged from the locking groove. After the position of the fence frame 2 is no longer restricted, it can be disengaged from the connecting groove 9.

[0025] Preferably, the inner wall of the connecting groove 9 is embedded with corrugated protrusions, and the outer wall of the grounding cone 8 is coated with an anti-corrosion layer. The protrusions increase the friction between the grounding cone 8 and the fence frame 2, improve the stability of the highway construction fence and the fixed frame 1 during installation, and the anti-corrosion layer plays a protective role, preventing the grounding cone 8 from rusting due to long-term contact with groundwater and extending its service life.
