Large-angle door opening structure of hidden fire hydrant

Abstract

A large-angle door opening structure of a hidden fire hydrant is characterized by comprising a rotating shaft A (1), two rotating shafts B (2), and two connecting pieces (3); upper and lower ends of the rotating shaft A (1) are fixed on a wall decorative plate fixing steel frame (4); the two rotating shafts B (2) are mounted on upper and lower ends of an inner side of a decorative door (5), respectively; one end of each connecting piece (3) is pivoted to the rotating shaft A (1), while the other end of the same is pivoted to one rotating shaft B (2); a strong magnetic limiting piece (6), which is capable of sucking the connecting piece (3) to facilitate closing and positioning of the decorative door, and also capable of separating from the connecting pieces under the action of an external force to facilitate opening, is mounted on a side surface (8) of a fire hydrant chamber (7); a first limiting element (9) for preventing excessive rotation of the connecting pieces (3) is mounted on an upper or lower surface of the fire hydrant chamber (7), or the first limiting elements (9) are mounted on both upper and lower surfaces of the same; and a second limiting element (10) for guaranteeing the close state of the decorative door (5) is mounted on the upper or lower surface of the fire hydrant chamber (7), or the second limiting elements (10) are mounted on both upper and lower surfaces of the same. The large-angle door opening structure of the hidden fire hydrant is large in opening angle, and capable of reducing the installation space, and reducing the construction cost.

Description

technical field [0001] The invention relates to a decoration technology, in particular to a decoration structure of a fire hydrant door body, in particular to a concealed fire hydrant large-angle door opening structure. Background technique [0002] As we all know, fire hydrants are necessary safety equipment for buildings, and there are two types of fire hydrants: obvious installation and concealed installation. Generally speaking, in order to ensure the overall decoration effect, the existing high-end places adopt the concealed installation method, that is, the fire hydrant is installed behind the wall decoration board, and the wall decoration board (such as stone) is used as the door panel of the concealed door. The words of the fire door are marked on the decorative panel. There are national standards for the installation and identification of secret doors. However, the applicant found that no matter what kind of structure the hidden fire hydrant door can meet the requ...
