Description

Technical Field

[0001] The utility model relates to a fence, in particular to a quick-limiting blow-molded fence for urban traffic. Background Art

[0002] A safety warning fence is a protective facility used to isolate special areas such as construction areas or unsafe areas, so that these special areas form a relatively enclosed space and play a warning role for the external area, and is often widely used in industries such as roads.

[0003] At present, a Chinese patent with the authorization announcement number CN213869236U discloses a warning fence for transportation safety, which includes two fixed columns, two fixed rods and a limiting rod. The bottoms of the two fixed columns are fixedly connected with fixed bases, and the bottoms of the fixed bases are fixedly connected with a plurality of support frames. The front of the support frame is threadedly connected with a locking bolt, the locking bolt penetrates through the support frame and enters the inside of the support frame, the bottom of the locking bolt is fixedly connected with a pressing block, the bottom of the pressing block is fixedly connected with a rubber pad, a support leg is arranged inside the support frame, sliding grooves are opened on both sides of the support leg, a spring is arranged at the top of the support leg, and a weight is fixedly connected to the bottom of the support leg.

[0004] This warning fence for transportation safety is placed more stably and can be placed stably on any terrain to prevent displacement and loss; however, in order to maintain stability, the support frame has three and forms a triangular frame; the support frame and the fixed base cannot be disassembled due to fixed connection, so the space volume occupied by this warning fence is relatively large, and it is inconvenient to carry and transport. Content of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a quick-limiting blow-molded fence for urban traffic, so as to achieve the purpose of being convenient for transportation and handling.

[0006] To solve the above technical problems, the technical solution of the utility model is: a quick-limiting blow-molded fence for urban traffic, including a protection plate. An installation groove is opened along the height direction of the lower end of the protection plate. A guiding groove communicating with the installation groove is opened on the surface of the protection plate. Positioning concave holes are opened on the inner wall of the guiding groove, and guiding inclined surfaces are opened at the openings of the positioning concave holes. A support plate is embedded in the guiding groove. A positioning column for being embedded in the positioning concave holes is fixedly connected to the surface of the support plate. A clamping plate is fixedly connected between adjacent support plates. The clamping plate abuts against the bottom wall of the installation groove. A support is fixedly connected between adjacent support plates. A support column is fixedly connected to the lower end of the support. The lower end of the support column has a support foot, and a fixing hole is opened on the support foot. After the support column penetrates into the fixing hole, the support foot rotates 90° and the support column is fixed in the fixing hole through a limiting structure.

[0007] To implement the above technical solution, hold the support column, and press the clamping plate against the bottom wall of the installation groove. At this time, the positioning column is inserted into the positioning concave hole, making it difficult for the support plate to slip out of the guiding groove. Sleeve the supporting leg on the support column, rotate the supporting leg by 90°, and place the support column in the fixing hole through the limiting structure. At this time, the supporting leg can provide good support for the protection plate. Similarly, rotate the supporting leg by another 90°, and the supporting leg can be removed from the support column. Apply a downward pulling force to the support column, and the positioning column can be pulled out of the positioning concave hole to separate the protection plate from the supporting leg and the support column, thereby reducing the occupied space volume for easy transportation and handling.

[0008] As a preferred solution of the present utility model, the limiting structure includes a limiting groove, a limiting plate, and a limiting hole. The limiting groove is opened on the inner wall of the fixing hole and arranged along the length direction of the fixing hole. The limiting plate is fixed to the lower end of the support column and is used for sliding connection in the limiting groove. The limiting hole is opened at the lower end of the fixing hole and communicates with the limiting groove.

[0009] To implement the above technical solution, insert the support column into the fixing hole. The limiting plate moves along the limiting groove and is placed in the limiting hole. At this time, rotate the supporting leg to misalign the limiting plate with the limiting groove, so that the support column cannot be pulled out of the fixing hole to achieve the limiting effect; rotate the supporting leg, and when the limiting plate corresponds to the limiting groove, the support column can be pulled out of the fixing hole for disassembly.

[0010] As a preferred solution of the present utility model, a plurality of reinforcing rods are fixedly connected between adjacent support plates, and the plurality of reinforcing rods are arranged along the length direction of the support plate.

[0011] To implement the above technical solution, the reinforcing rods can increase the structural strength between the two support plates, and when the protection plate is affected by crosswind, it is difficult for the support plate to break.

[0012] As a preferred solution of the present utility model, a weight-reducing hole is opened on the side wall of the support column.

[0013] To implement the above technical solution, the mass of the support column is reduced for easy transportation and handling.

[0014] As a preferred solution of the present utility model, one end of the protection plate is fixedly connected with an extension plate, and a connecting pipe is fixedly connected to the extension plate.

[0015] To implement the above technical solution, by dragging the connecting pipe, it is convenient to drag the protection plate to move.

[0016] As a preferred solution of the present utility model, a connecting rod is fixedly connected to the end of the protection plate away from the extension plate, and the connecting rod is used to penetrate into the connecting pipe.

[0017] To implement the above technical solution, the connecting rod on one protective plate is inserted into the connection on another protective plate to connect multiple protective plates and improve the structural stability.

[0018] As a preferred embodiment of the present invention, an auxiliary structure for restricting the rotation of the limiting plate is provided on the supporting leg.

[0019] To implement the above technical solution, the auxiliary structure makes it difficult for the limiting plate to rotate on the supporting leg.

[0020] As a preferred embodiment of the present invention, the auxiliary structure includes an adjustment hole, an elastic member, an adjustment bolt, a T-shaped column, and a positioning hole. The adjustment hole is opened on the side wall of the supporting leg and communicates with the limiting hole. The adjustment hole is located between two limiting grooves. The positioning hole is opened at the end of the limiting plate. The T-shaped column is slidably connected to the adjustment hole and the end of the T-shaped column is used to abut against the inner wall of the positioning hole. The elastic member is placed in the adjustment hole. The adjustment bolt is threadedly connected to the adjustment hole. Both ends of the elastic member respectively abut against the end of the T-shaped column away from the positioning hole and the adjustment bolt.

[0021] To implement the above technical solution, the limiting plate is inserted into the limiting hole along the limiting groove, and the supporting leg is rotated. When the positioning hole corresponds to the end of the T-shaped column, due to the elastic force of the elastic member, the T-shaped column is embedded into the inner wall of the positioning hole, and the generated frictional force realizes the positioning of the limiting plate, making it difficult for the supporting leg and the limiting plate to rotate relative to each other, thus playing an auxiliary positioning role; overcoming this frictional force, the supporting leg is rotated to disengage the T-shaped column from the positioning hole; by rotating the adjustment bolt, the compression degree of the elastic member can be adjusted, and the tightness between the T-shaped column and the positioning hole can be adjusted.

[0022] As a preferred embodiment of the present invention, a connecting concave hole is opened on one side of the protective plate, and a connecting protrusion is fixedly connected to the other side of the protective plate. The connecting concave hole and the connecting protrusion correspond to each other.

[0023] To implement the above technical solution, the connecting protrusion is embedded into the connecting concave hole, so that multiple protective plates can be stacked together for convenient overall handling of multiple protective plates. BRIEF DESCRIPTION OF THE DRAWINGS
