A kind of closing device of opening T-shaped door

Abstract

The invention discloses a closing device for an opposite-opening T-shaped door. The closing device comprises a wall body. Opening and closing rotating shafts which are in left-right symmetry are rotationally arranged in the wall body. T-shaped doors are installed on the opening and closing rotating shafts. A locking groove is formed in the upper end face of each T-shaped door, and a locking deviceis arranged on the upper side of each T-shaped door. Each locking device comprises a locking block which can slide in a lifting manner, wherein the locking block can be inserted in the correspondinglocking groove to lock the corresponding T-shaped door. A rotating device is arranged on the side, away from the symmetric center, of each locking device. By means of the closing door for the opposite-opening T-shaped door, the rotating devices are used for controlling the T-shaped doors on the left side and the right side to rotate, and due to self-locking structures of worm gears and worms, theopening and closing positions of the T-shaped doors are stable; and in addition, opening and closing of the T-shaped doors have a single opening mode and a double opening mode, when the T-shaped doorson the left side and the right side are in the double opening mode, the sequence of opening and closing is fixed, protruding parts of the T-shaped doors are stably connected, the sealing performanceis good, the opening and closing automatic operation of the T-shaped doors is achieved, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to a closing device for a split T-shaped door. Background technique [0002] T-shaped door, also known as T-port door and German-style door, is a kind of door panel that looks like a capital letter T from above. It is equipped with a sealing strip, which is sealed and soundproof, has good thermal insulation effect and is beautiful as a whole. Due to the special structure of the T-shaped door, the joint positions of the T-shaped doors on both sides are fixed, but in actual use, the protrusions of the T-shaped door overlap. If the connection is unreasonable, the door cannot be tightly fitted, and it needs to be adjusted manually, which is inconvenient to operate and use. The present invention sets forth a device capable of solving the above-mentioned problems. SUMMARY OF THE INVENTION [0003] technical problem: [0004] When the existing T-shaped door is opened and clo...

Problems solved by technology

[0002] T-shaped door, also known as T-door or German-style door, is a kind of door panel that looks like a capital letter T from above. Compared with the traditional flat mouth, it gets its name. The protruding part of the T-shaped door is pressed against the door pocket. It is equipped with sealing strips, which are sound-proof and sound-proof, with good thermal insulation effect and overall beautiful appearance. Due to the special structure of the T-shaped door, the joint positions of the T-shaped doors on both sides are fixed, but in actual use, the protrusions of the T-shaped door overlap. The connection is unreasonable, so that the door cannot be tightly fitted, and manual adjustment is required, which is inconvenient to operate and use
