DETAILED DESCRIPTION

[0024] The utility model is described in detail below with reference to the accompanying drawings and embodiments.

[0025] Reference Figure 1-2 As shown, the utility model provides an invisible door node for fire hydrants with special wall shapes.

[0026] Example 1

[0027] It includes a door frame 1 fixed on the inner side frame of the decorative surface, a door body 2 whose size matches that of the door frame, and a hinge structure 3 connected between the door body and the door frame;

[0028] The hinged structure includes a first rotating shaft 3-1, an intermediate rotating shaft 3-2, and a second rotating shaft 3-3, which are all arranged vertically. The first rotating shaft is arranged vertically at one end of the top and bottom of the door frame, and a first connecting member 3-4 and a second connecting member 3-5 are respectively provided between the first rotating shaft and the intermediate rotating shaft, and between the intermediate rotating shaft and the second rotating shaft; one end of the first connecting member is hinged to the bottom of the door frame and one end of the bottom through the first rotating shaft, and the other end is hinged to the intermediate rotating shaft; one end of the second connecting member is hinged to the intermediate rotating shaft, and the other end of the second connecting member is hinged to the inner side surface of the door body through the second rotating shaft; when the door body is located in the door frame, the first rotating shaft and the second rotating shaft are located on the same side of the intermediate rotating shaft, and the lengths of the first connecting member and the second connecting member are set according to needs.

[0029] By setting up a hinged structure, and setting three vertically arranged first rotating shafts, an intermediate rotating shaft, and a second rotating shaft in the hinged structure; using the above hinged structure, when the door body needs to be opened, the operation of the door body is divided into two stages.

[0030] In the first stage, one end of the first connecting member rotates around the first rotating shaft in a direction away from the plane where the door frame is located, and one end of the second connecting member rotates around the middle rotating shaft in the opposite direction to the first connecting member; and under the action of the second rotating shaft, the door body is always in a parallel state with the door frame. Since the direction of movement of the door body is parallel to the plane where the door frame is located during the opening process of the door body in the first stage; therefore, only a small gap is required between the door body and the door frame, and no interference will occur during the opening process of the door body.

[0031] In the second stage, when the door body is completely moved into the range of the door frame, the door body and the hinged structure are rotated as a whole with the first rotation axis as the rotation center in the direction away from the plane where the door frame is located, or the door body is rotated with the second rotation axis as the rotation center in the direction away from the plane where the door frame is located, thereby achieving full opening of the door body.

[0032] Based on the above measures and structures, as shown in the figure, the opening of the door body is divided into two stages. The first stage is to pull the door body out in a direction perpendicular to the door body (see the first state A of the fire hydrant door in the figure), and the second stage is to rotate the door body with the first rotating shaft as the rotation center in a direction away from the plane where the door frame is located to open (see the second state B of the fire hydrant door in the figure); the gap between the door body and the door frame can be effectively reduced, the normal opening of the door body is ensured, and the aesthetics of the overall structure of the hidden door is improved.

[0036] The structure and principle of Example 3 are similar to those of Example 1, except that: in order to ensure that the door body can be smoothly moved out of the door frame area, the maximum distance between the first fixed rotating shaft and the second rotating shaft must be greater than the thickness of the fire hydrant door body. Preferably, the thickness of the fire hydrant door is h, and the maximum distance between the first fixed rotating shaft and the second rotating shaft is not less than 1.5h.

[0037] In Examples 1-3, a preferred structural form of the first connecting member and the second connecting member is given. The first connecting member and the second connecting member are both composed of a horizontal connecting rod and a sleeve, the sleeve is provided at both ends of the horizontal connecting rod, and the inner diameter of the sleeve matches the outer diameter of the connected rotating shaft; one end of the horizontal connecting rod is rotatably connected to the intermediate rotating shaft, and the other end of the horizontal connecting rod is rotatably connected to the first rotating shaft or the second rotating shaft; and a groove is provided on the rotating shaft to limit the sleeve from sliding up and down on the rotating shaft.

[0038] On this basis, the structural strength of the first connecting member and the second connecting member can be further enhanced by connecting all horizontal connecting rods in the first connecting member into a whole through vertical rods; and connecting all horizontal connecting rods in the second connecting member into a whole through vertical rods.

[0039] The first connecting member and the second connecting member may also adopt other structures, as long as the two ends are respectively arranged on the middle rotating shaft and the first rotating shaft or the second rotating shaft in a rotationally connected manner.

[0043] The structure and principle of the fifth embodiment are similar to those of the first embodiment, except that another structure of the first rotating shaft and the second rotating shaft is provided. The first rotating shaft, the second rotating shaft, and the intermediate rotating shaft all adopt a single structure.

[0044] In embodiments 1-5, a rotating shaft fixing frame is fixedly provided on the inner wall of the door body, the frame is composed of a plurality of crisscrossed square steels, a rotating shaft seat is provided on the frame, and the second rotating shaft is rotatably connected to the rotating shaft seat on the inner wall of the door body;

[0045] A rotating shaft seat is provided on the side surface, or the ends of the top surface and the bottom surface of one side of the door frame, and the first rotating shaft is placed in the rotating shaft seat.

[0046] The above are only preferred embodiments of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the protection scope of the present invention.
