Technical Field

[0001] The utility model relates to a field where roads are further optional, and in particular to a separation fence door. Background Art

[0002] Highway fences are protective facilities specially designed to ensure highway safety, prevent pedestrians and animals from crossing the road, and reduce the frequency of traffic accidents, so as to ensure that the highway is fully closed. However, this has a certain impact on the rapid passage of maintenance, firefighting, emergency and other personnel. Therefore, it is particularly important to develop a door that can quickly pass through the fence. Utility Model Content

[0005] A fence door comprises two side columns and a crossbeam connected to their upper parts, wherein one side column is hinged with a door frame through multiple door shafts, the door frame is provided with a door mesh, the door frame is connected to the other side column through a door lock, and the lower parts of the two sides of the door frame are hinged with flippable and foldable lower frames through hinges, and the lower frame is connected to the upper door lock through a locking mechanism.

[0006] Further optionally, both sides of the upper portion of the lower frame are hingedly fixed to the bottom end of the connecting rod through hinges, and the top of the connecting rod is hingedly fixed to the corresponding side portions of the door frame through hinges.

[0007] Further optionally, the door mesh installed on the door frame extends downward and is fixed to the connecting rod and the lower frame.

[0008] Further optionally, the locking mechanism includes a coaxial positioning sleeve arranged on the lower frame, the connecting rod, and the side of the door frame, a positioning rod is inserted in the positioning sleeve, and a limiting sleeve connected to the top of the positioning rod and sleeved with the rod of the door lock is connected to the top of the positioning rod.

[0009] Further optionally, the tops of the two side columns are connected with outwardly inclined rods, and the inclined rods are connected with barbed wires through multiple hooks.

[0010] Further optionally, the bottoms of the columns on both sides are connected and fixed to the embedded foundation.

[0011] Further optionally, a plurality of connecting plates for mounting the isolation mesh are fixed to the outer ends of the two side columns.

[0012] Compared with the existing technology, the beneficial effects of the utility model are: the utility model has a simple structure and is easy to install; it has strong resistance to external force deformation, is easy to open and close and disassemble, adapts to more scenes and environments, and is easy to pass through. At the same time, a flip and foldable lower frame is provided at the lower part.

DETAILED DESCRIPTION

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0017] like Figure 1 , 2 As shown, a fence door includes two side columns 1 and a crossbeam 2 connected to the upper part thereof, the columns 1 are made of high-strength lightweight metal material, and the surface is treated to enhance wear resistance and weather resistance, wherein one side column 1 is hinged with a door frame 4 through multiple door shafts 6, the door frame 4 is provided with a door mesh 5, the door mesh 5 is welded on the door frame 4, the door mesh 5 is provided with a flexible metal mesh, the door frame 4 is connected to the column 1 on the other side through a door lock, the lower parts of the two sides of the door frame 4 are hinged with a flip-foldable lower frame 7 through hinges 9, and the lower frame 7 is connected to the upper door lock through a locking mechanism.

[0018] The upper sides of the lower frame 7 are hinged and fixed to the bottom end of the connecting rod 8 through hinges 9, and the top of the connecting rod 8 is hinged and fixed to the corresponding side of the door frame 4 through hinges 9. The lower frame 7 can be flipped and folded through the hinge 9 to leave space at the bottom to interfere with weeds.

[0019] The door mesh 5 installed on the door frame 4 extends downward and is fixed to the connecting rod 8 and the lower frame 7, so that a fence door as a whole is formed, which has good sealing performance.

[0020] The locking mechanism includes a coaxial positioning sleeve 10 arranged on the side of the lower frame 7, the connecting rod 8, and the door frame 4. A positioning rod 11 is inserted in the positioning sleeve 10. The top of the positioning rod 11 is connected to a limiting sleeve 12 which is sleeved with the door lock rod. The locking mechanism is opened and closed as the door lock rod is opened.

[0021] The tops of the two side columns 1 are connected with outwardly inclined tilting rods 14, and the tilting rods 14 are connected with barbed wires 16 through a plurality of hooks 15, so that the barbed wires 16 prevent people from climbing over.

[0022] The bottoms of the columns 1 on both sides are connected and fixed to the embedded foundation 3. The embedded foundation 3 is prefabricated with C25 and above ordinary concrete, 30cm*30cm*30cm or a cube shape of appropriate size, depending on the situation.

[0023] A plurality of connecting plates 17 for mounting isolation meshes are fixed to the outer ends of the two side columns 1 .

[0024] The implementation principle of an isolation fence door in the embodiment of the present application is:

[0025] The prefabricated concrete embedded foundation 3 is embedded in the ground. The embedding distance between the two embedded foundations 3 should be accurately calculated. The column 1 is fixed on the embedded foundation 3 with expansion bolts. The door frame with door mesh 5 is installed. The upper part of the door shaft 6 is inserted into the lower part of the shaft sleeve of the column 1. The door lock plug rod is in a closed state. The crossbeam 2 is installed. Then the connecting plate 17 is connected to the isolation mesh of the isolation fence, and the double-strand barbed wire 16 is used for binding. When the isolation fence is not in use, it can be closed with a plug-in door lock. When in use, the door lock is opened to allow maintenance, fire fighting, emergency and other personnel to pass quickly;

[0026] When there are a lot of weeds at the bottom of the door frame 4, which blocks the lower part of the door frame 4 and affects its opening, the door lock can be opened to disengage the door lock rod 13 from the limiting sleeve 12, and then the limiting sleeve 12 and the positioning rod 11 can be pulled upward out of the multiple positioning sleeves 10 at the bottom, so that the lower frame 7 at the bottom can be flipped and folded along the connecting rod 8 without restriction. In this way, the space generated at the bottom of the door frame 4 will not interfere with the weeds, which is convenient for the opening of the door frame 4. When it is opened for use and closed, the positioning rod 11 is restored in the reverse direction and locked with the door lock. In this way, the lower frame 7 and the connecting rod 8 at the bottom of the door frame 4 are restricted by the positioning rod 11 and will not be in a loose state.

[0027] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
