[0022] Various embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. In each of the accompanying drawings, identical elements are represented by identical or similar reference numerals. For the sake of clarity, the various parts in the accompanying drawings are not drawn to scale.

[0023] The utility model provides a hinge device for a hidden fire hydrant door. Figure 1 The hinge device for a hidden fire hydrant door includes: a fixed rod 1, a hinge 2, a channel steel 3 and a movable rod 4; wherein the fixed rod 1 is used to be fixed on the fire hydrant box 6, and the movable rod 4 is used to be fixed on the fire hydrant box door 7; the two wing plates of the channel steel 3 are respectively hinged to the fixed rod 1 and the movable rod 4 through the hinge 2.

[0024] See also Figure 2and Figure 3 The hidden fire hydrant box includes a box body 6 and a box door 7. The box body 6 is concealedly installed in the wall of the building's fire passage. When the box door 7 is closed, the outer side of the box door 7 is flush with the building wall. The door panel of the box door 7 is made of wood veneer, stone, dry-hanging tiles, etc. that match the building wall. The box body 6 is designed to be open on the front side. The fixed rod 1 of the hinge device of the hidden fire hydrant door is fixedly connected to one side of the open end of the box body 6, and the movable rod 4 is fixedly connected to one side of the inner surface of the box door 7. The movable rod 4 can be used as a part of the inner side support frame of the box door 7 and connected to the inner side support frame of the box door 7 for use as a whole. The door panel on the outside of the box door 7 extends to a preset length toward one side of the channel steel 3. When the box door 7 is opened, the extended part of the outer door panel of the box door 7 swings into the notch of the channel steel 3. When the box door 7 is closed, the extended part of the outer door panel of the box door 7 can block the channel steel 3.

[0025] The hinge device for a concealed fire hydrant door is configured by arranging a channel steel 3 so that the two wing plates of the channel steel 3 are hinged to the fixed rod 1 and the movable rod 4 respectively through a hinge 2. When the hinge device is applied to a concealed fire hydrant box, the opening angle of the box door 7 is increased. When the box door 7 is opened, the hinge 2 on the fixed rod 1 can be used to open the box door 7 first. If it is found that the opening angle of the box door 7 cannot meet the requirement, the hinge 2 on the movable rod 4 can be used to continue opening the box door 7 so that the box door 7 meets the opening angle requirement. The box door 7 can be opened to a maximum of 180 degrees, does not occupy passage space, and is convenient for the use of fire hydrants.

[0026] Furthermore, there are at least two channel steels 3 and they are spaced apart along the length direction of the fixed rod 1. In this embodiment, there are two channel steels 3, which are respectively arranged at the upper and lower ends of the fixed rod 1 and the movable rod 4.

[0027] Furthermore, the channel steels 3 are connected by a reinforcing rod 5, which is fixedly connected to the web of the channel steels 3. By providing the reinforcing rod 5, the channel steels 3 spaced apart along the length of the fixing rod 1 can be rigidly connected together. When the door 7 is opened, all the channel steels 3 can rotate synchronously, thereby improving the overall stability.

[0028] Furthermore, the reinforcing rod 5 is made of a rectangular steel tube or a square steel tube, and the fixed rod 1 and the movable rod 4 are both made of a rectangular tube or a square tube. In this embodiment, the fixed rod 1 and the movable rod 4 are both made of a square steel tube, and the fixed rod 1 is made of a rectangular steel tube. The fixed rod 1 is fixedly connected to the frame at the open end of the front side of the box body 6 by welding, and the movable rod 4 is fixedly connected to the support frame on the inner side of the box door 7 by welding, and the reinforcing rod 5 is fixedly connected to the web of the channel steel 3 by welding. Preferably, the fixed rod 1 and the movable rod 4 are both made of a galvanized rectangular steel tube or a galvanized square steel tube, and the reinforcing rod 5 is made of a galvanized rectangular steel tube or a galvanized square steel tube to improve the corrosion resistance of the hinge device. It is understandable that the fixed rod 1, the movable rod 4, and the reinforcing rod 5 can also be made of a rectangular tube or a square tube made of stainless steel.

[0029] Furthermore, the channel steel 3 is formed by bending a steel plate. Preferably, the width of the web of the channel steel 3 is smaller than the width of the wing plate, so as to prevent the extended portion of the outer door panel of the door 7 from interfering with the channel steel 3 when the door 7 is opened.

[0030] Furthermore, the fixed rod 1, the movable rod 4 and the channel steel 3 are connected to the blades of the hinge 2 by screw connection, riveting or welding. Among them, it is preferred to use screw connection or riveting to connect the blades of the hinge 2 to the movable rod 4, the movable rod 4 and the channel steel 3. Compared with the connection by welding, the hinge 2 connected by screw connection or riveting can avoid deformation caused by welding and improve the overall aesthetics of the concealed fire hydrant box.

[0031] In summary, the hinge device for a hidden fire hydrant door provided by the present invention is configured by arranging a channel steel so that the two wing plates of the channel steel are hinged to a fixed rod and a movable rod respectively through a hinge. When in use, the fixed rod is fixed on the box body of the fire hydrant, and the movable rod is fixed on the box door of the fire hydrant, which can enable the hidden fire hydrant door to be opened to a maximum of 180 degrees without occupying the passage space, thereby facilitating the use of the fire hydrant.
