DETAILED DESCRIPTION
[0021] The utility model is described in detail below with reference to the accompanying drawings and embodiments.
[0022] Reference Figure 1 to Figure 4 As shown, the utility model provides a connection structure suitable for thickening a wall surface and a fire hydrant door.
[0023] Example 1
[0024] It includes a first rotating frame 1 and a second rotating frame 2, and a first fixed rotating shaft 3, an intermediate rotating shaft 4, and a second fixed rotating shaft 5 which are all arranged vertically. One side of the first rotating frame is rotatably connected to the wall 7 facing the inner side of the fire hydrant door 6 through the first fixed rotating shaft, the other side of the first rotating frame is connected to one side of the second rotating frame through the intermediate rotating shaft, and the other side of the second rotating frame is rotatably connected to the inner wall of the fire hydrant door through the second fixed rotating shaft; when the fire hydrant door is in a closed state, the first rotating frame, the second rotating frame and the intermediate rotating shaft are stored in the space formed by the fire hydrant door and the wall.
[0025] In this embodiment, three vertically arranged first fixed rotating shafts, an intermediate rotating shaft, and a second fixed rotating shaft are provided; when the fire hydrant door needs to be opened, a force perpendicular to the direction of the outer wall of the fire hydrant door is first applied to the fire hydrant door, at which time the first rotating frame rotates a certain angle around the first fixed rotating shaft, the second rotating frame rotates a certain angle around the intermediate rotating shaft, and the fire hydrant door rotates a certain angle around the third fixed rotating shaft, so that the fire hydrant door is pulled open in a direction perpendicular to the wall.
[0026] After the above operations, the fire hydrant door is completely pulled out of the groove between the walls; then, with the middle rotating shaft as the center, the fire hydrant door is rotated to the left or right as needed, so as to achieve full opening of the fire hydrant door; in this process, the first rotating frame will rotate a certain angle around the first fixed rotating shaft, and the fire hydrant door will rotate a certain angle around the third fixed rotating shaft.
[0027] Based on the above measures and structures, such as Figure 4As shown, the opening of the fire hydrant door is divided into two steps. The first step is to pull the door body out in a direction perpendicular to the door body (see the first state 6-1 of the fire hydrant door in the figure), and the second step is to push the door body to the left or right side of the fire-fighting facility as needed (see the second state 6-2 of the fire hydrant door in the figure); it is suitable for closing fire hydrant doors of various thickened walls without increasing costs, and makes the opening and closing of the fire hydrant door more flexible and the opening space larger.
[0028] In Example 1, the distance between the first fixed rotating shaft and the middle rotating shaft must be greater than the thickness of the fire hydrant door body; the distance between the middle rotating shaft and the second fixed rotating shaft must meet the requirement that the fire hydrant door does not cause obstruction to the fire-fighting facilities when it is located at the extreme left or right side.
[0029] Example 2
[0030] The structure and principle of Example 2 are similar to those of Example 1, except that: preferably, the thickness of the fire hydrant door is h, the spacing between the first fixed rotating shaft and the intermediate rotating shaft is 1.3h~2h, and the spacing between the intermediate rotating shaft and the second fixed rotating shaft is 2.5h~3h.
[0031] Example 3
[0032] The structure and principle of Example 3 are similar to those of Examples 1 and 2, except that a preferred structure of the first rotating frame and the second rotating frame is provided.
[0033] Specifically, the first rotating frame and the second rotating frame are both composed of a horizontal connecting rod and a sleeve. The sleeve is arranged 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 fixed rotating shaft or the second fixed rotating shaft; and a groove is provided on the rotating shaft to limit the sleeve from sliding up and down on the rotating shaft.
[0034] The structural strength of the first rotating frame and the second rotating frame can also be further enhanced on the basis of Example 3 by connecting all the horizontal connecting rods in the first rotating frame into a whole through vertical rods; and connecting all the horizontal connecting rods in the second rotating frame into a whole through vertical rods.
[0035] Example 4
[0036] The structure and principle of Example 4 are similar to those of Example 3, except that the first fixed rotating shaft and the second fixed rotating shaft adopt a segmented structure, and the middle rotating shaft adopts a single-root structure.
[0037] Of course, the first fixed rotating shaft and the second fixed rotating shaft may also adopt a single structure, but the single structure occupies a large space and is likely to interfere with other components of the fire-fighting facility during installation, making the overall installation difficult.
[0038] In Example 4, preferably, the first fixed rotating shaft and the second fixed rotating shaft are divided into two sections or three sections, and the sections of the first fixed rotating shaft and the second fixed rotating shaft are staggered; the embodiment in the figure is divided into upper and lower sections.
[0039] In Examples 1-4, in order to facilitate the installation of the first fixed rotating shaft and the second fixed rotating shaft on the wall and the fire hydrant door, a rotating shaft fixing frame 8 is fixedly provided on the inner wall of the fire hydrant door and the wall directly opposite the fire hydrant door. The frame is composed of a plurality of criss-crossed square steels, and a rotating shaft seat is provided on the frame. The first fixed rotating shaft and the second fixed rotating shaft are respectively rotatably connected to the rotating shaft seats on the inner wall of the fire hydrant door or the wall directly opposite the fire hydrant door.
[0040] like Figure 3-4 As shown, the utility model also provides a fire hydrant door suitable for thickened walls, which adopts the connection structure suitable for thickened walls and fire hydrant doors as described above; it also includes a door body and a rebound door buckle 9 arranged between the side walls around the inner side of the door body.
[0041] In this embodiment, the rebound door catch adopts the existing technical structure. When the fire hydrant door needs to be opened, the rebound door catch is opened, and the rebound door catch bounces the door body in a direction perpendicular to the wall. At this time, the door body is completely separated from the area where the door frame is located; then, according to the needs, a force is applied to the door body to the left or right to push the door body to the left or right side of the fire-fighting facility. After the door body moves to the left or right side of the fire-fighting facility, a hook 10 can also be set to fix the position of the door body, so that the fire hydrant door is in a normally open state.
[0042] 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 patent application of the present invention still fall within the protection scope of the present invention.
