Description

Technical Field

[0001] The invention relates to the technical field of indoor fire hydrant hidden door installation, in particular to a fire hydrant hidden door rotating shaft device. Background Art

[0002] In interior decoration projects, tightly spliced ​​wall panels are increasingly being used in public spaces such as large conference centers and lecture halls to create a cohesive effect. When installing indoor fire hydrant concealed doors, compliance with regulations for their opening and aesthetics is particularly important, particularly regarding their opening method and angle. Conventional fire hydrant doors typically rotate on a single axis. If insufficient internal space is encountered, this not only affects the opening angle but also fails to meet regulatory requirements for greater than 120°. Furthermore, if the panels are installed tightly spliced, a natural gap will inevitably remain at the concealed door location, compromising the overall decorative effect. Summary of the Invention

They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] Furthermore, it should be understood that for the sake of ease of description, the sizes of the various components shown in the drawings are not drawn according to actual proportions. For example, the thickness or width of certain layers may be exaggerated relative to other layers.

[0025] It should be noted that like numbers and letters represent similar items in the following figures, so once an item is defined or described in one figure, it will not need to be further discussed and described in detail in the description of the subsequent figures.

[0026] refer to Figure 1-Figure 4 This embodiment also provides a fire hydrant hidden door hinge device, which includes a fire hydrant 1, a U-shaped rotating shaft 2, and a telescopic decorative panel 5. One side of the fire hydrant 1 is connected to the inward side of the U-shaped rotating shaft 2 via a movable rotating shaft 3, and the other side of the fire hydrant 1 is provided with a lock 4. At the same time, the outward side of the U-shaped rotating shaft 2 is movably connected to the inward side of the telescopic decorative panel 5 via a sliding connecting shaft 6. It is worth noting that a lock is provided on the outward side of the U-shaped rotating shaft 2, wherein the lock and the lock 4 are adapted to each other, that is, the lock can be inserted into the interior of the lock 4.

[0027] In this embodiment, a movable frame 7 is provided inside the U-shaped rotating shaft 2, and a telescopic decorative panel 5 is provided inside the movable frame 7. It is worth noting that the outer diameter of the telescopic decorative panel 5 is the same as the inner diameter of the movable frame 7, and the outer diameter of the U-shaped rotating shaft 2 is the same as the inner diameter of the fire hydrant 1. At the same time, the outer surface of the fire hydrant 1, the outer surface of the U-shaped rotating shaft 2, and the outer surface of the telescopic decorative panel 5 are located on the same horizontal plane. That is to say, when the telescopic decorative panel 5 is extended into the interior of the movable frame 7 through the sliding connecting shaft 6, and the U-shaped rotating shaft 2 is merged with the fire hydrant 1 through the movable rotating shaft 3, the outer surface of the fire hydrant 1 is flush with the lock and the lock buckle 4. Moreover, the setting of the telescopic decorative panel 5 can better hide the position of the fire hydrant 1, thereby achieving a beautifying effect.

[0028] In this embodiment, the U-shaped rotating shaft 2 includes a shaft frame 201, which is disposed at both ends of the inward-facing side of the telescopic decorative panel 5. Specifically, one end of the shaft frame 201 is connected to the movable rotating shaft 3, and the other end of the shaft frame 201 is connected to the sliding connecting shaft 6. Furthermore, a sliding rail 202 is provided within the shaft frame 201. A locking block 204 is disposed on one side of the shaft frame 201. The locking block 204 is disposed at one end of the interior of the sliding rail 202, and the locking block 204 and the end of the sliding connecting shaft 6 are connected by a connecting chain 203. In this embodiment, one end of the sliding connecting shaft 6 is connected to the inward-facing end of the telescopic decorative panel 5, and the other end of the sliding connecting shaft 6 is disposed within the interior of the sliding rail 202, and the interior of the sliding rail 202 is connected to the end of the sliding connecting shaft 6. A baffle 205 is disposed on the outward-facing side of the movable frame 7, wherein the outer surface of the baffle 205 is coplanar with the outer surface of the movable frame 7. The sum of the widths of the baffle 205 and the telescopic decorative panel 5 is the same as the width of the U-shaped rotating shaft 2. In other words, when the telescopic decorative panel 5 extends into the interior of the movable frame 7, its entirety is the same size as the U-shaped rotating shaft 2.

[0029] In this embodiment, the use process of the fire hydrant hidden door hinge device is as follows:

[0030] When the fire hydrant 1 needs to be opened, first press the side of the U-shaped rotating shaft 2 where the lock is installed. At this time, the U-shaped rotating shaft 2 will automatically pop outward, and then the outward side of the telescopic decorative panel 5 is pulled outward. Through the action of the sliding connecting shaft 6, the telescopic decorative panel 5 can be pulled out of the interior of the movable frame 7.

[0031] When the fire hydrant 1 needs to be closed, first push the outward side of the telescopic decorative panel 5 inward, then the telescopic decorative panel 5 will extend into the interior of the movable frame 7, and then insert the lock piece into the interior of the lock buckle 4 to close the fire hydrant 1.

[0032] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
