Abstract

The invention discloses a horizontal pushing type firefighting blank door which comprises first-layer connecting rods, second-layer connecting rods, third-layer connecting rods and a door plank. The two first-layer connecting rods are symmetrically arranged in the vertical direction, the two second-layer connecting rods are symmetrically arranged in the vertical direction, the two third-layer connecting rods are symmetrically arranged in the vertical direction, and the first-layer connecting rods, the second-layer connecting rods and the third-layer connecting rods are arranged in a layered manner from the two sides to the middle portion. The upper side first-layer connecting rod is fixed to a door frame, and the bottom face of the outer end of the upper side first-layer connecting rod isprovided with a first rotating shaft. The upper side second-layer connecting rod is located below the upper side first-layer connecting rod and is connected with a first rotating shaft through a second rotating shaft at the inner end of the upper side second-layer connecting rod, and the bottom face of the outer end of the upper side second-layer connecting rod is provided with a third rotating shaft. The upper side third-layer connecting rod is connected with the third rotating shaft through a fourth rotating shaft which is arranged at the inner end of the upper side third-layer connecting rod. The upper side third-layer connecting rod and the lower side third-layer connecting rod are connected through vertical connecting rods to form an outer frame, and the door plank is arranged on theouter side face of the outer frame. By means of the horizontal pushing type firefighting blank door, the blank door is firstly drawn to disengage from the door frame through rotating and moving of theconnecting rods, then horizontal pushing is conducted to avoid the position, and it is ensured that the opening angle of the firefighting blank door meets the requirements; and the horizontal pushingtype firefighting blank door has the beneficial effects that the structure is simple, use is convenient, the occupied space is small, and the opening angle is large.

Description

technical field [0001] The invention relates to the field of indoor fire-fighting trap doors, in particular to a horizontal push type fire-fighting trap door. Background technique [0002] With the continuous improvement of people's aesthetic concept, in recent years, the original fire doors have been gradually replaced by fire trap doors. However, the common fire trap doors on the market can only be opened to about 90 degrees, and the opening degree of the trap door will be affected by the decorative layer during use. At the same time, according to the latest fire acceptance regulations, the opening angle of the fire box hidden door is not less than 160 degrees. Therefore, a "double-axis fire trap door" has been derived on the market. Although this scheme can meet the opening angle requirements, when the facing material is too thick, the demand for the thickness of the base layer will increase accordingly. At the construction site, due to the The problem of the relative t...
