Information shared type automatic door closing device

Abstract

The invention discloses an information shared type automatic door closing device. The information shared type automatic door closing device comprises a machine body and a first cavity arranged in themachine body, the inner wall of the left end of the first cavity is fixedly connected with a conversion box, a conversion cavity is formed in the conversion box, and a connecting rod extending leftwards and rightwards is connected to the inner wall of the left end of the conversion cavity in a sliding fit mode; and the tail end of the left end of the connecting rod is provided with a connecting hole which extends out of the end surface of the left end of the machine body in a penetrating mode, a recovery rod positioned at the right end of the connecting hole is arranged on the end surface of the upper end of the connecting rod, the right end of the connecting rod is fixedly connected with a piston which is connected with the upper inner wall and the lower inner wall of the conversion cavity in a sliding fit mode, and first limiting blocks which are positioned at the left end of the piston and are in up-down vertical symmetry are connected in the conversion cavity in a sliding fit mode.The information shared type automatic door closing device is simple in structure and convenient to operate, the air outlet displacement is controlled to control the door closing speed, and meanwhile,the power for rotating a door is used to realize automatic door closing action so as to save energy.

Description

technical field [0001] The invention relates to the technical field of intelligent furniture, in particular to an information sharing type automatic door closer. Background technique [0002] Doors in modern furniture are a necessity for home improvement. Due to the existence of human forgetfulness, many people will forget to close the door after opening it. This will not only run outdoor insects into the home, but also give criminals the opportunity to endanger their own safety. The existing door closers are generally controlled by electric union signals and are easy to break, and the working speed of such door closers is generally locked, which will cause harm to people with limited mobility, such as children and the elderly. Therefore a kind of new-type device with slowing speed and adjustment becomes the inevitable trend of development today, and the present invention illustrates a kind of information sharing type automatic door closer that can solve the above-mentione...
