A laboratory ventilation pipe safety cover with sealing and locking function

Abstract

The invention discloses a laboratory ventilation pipe security cover with sealing and locking functions. The laboratory ventilation pipe security cover with the sealing and locking functions comprises flywheels, a wall body, chains, a magnet and neodymium magnets; the flywheels are fixed to the wall body; bearing bases are fixed to the bottom of the wall body, and the wall body and the bearing bases are provided with connecting grooves correspondingly; operating plates are connected with inner plates, and the inner plates are connected with the wall body and provided with penetrating windows; and the penetrating windows are connected with movable plates, and the neodymium magnets are installed at the ends, far away from the penetrating windows, of the movable plates. According to the laboratory ventilation pipe security cover with the sealing and locking functions, the novel structural design is adopted, therefore, the device can be quickly triggered to work when abnormal conditions occur in a laboratory, and stable sealing operation can be conducted on a pipeline port of a laboratory ventilation pipe; and in addition, a sealing structure can be stably locked, loosing and air leaking can not prone to occurring, indoor and outdoor air exchange channels are thoroughly sealed, and the good laboratory security effect is achieved.

Description

technical field [0001] The invention relates to the technical field of security equipment, in particular to a laboratory ventilation pipe security cover with a sealing and locking function. Background technique [0002] Security is safety protection, and security equipment is a device that has a certain protective effect and can cope with attacks or avoid victims, so that the protected object is in a state of no danger, no infringement, and no accidents. The process of testing in the laboratory Among them, due to the variety of raw materials used in the experiment, many of them are flammable and explosive or easy to generate harmful gases during use. In order to ensure the safety of laboratory personnel and equipment, laboratories often use security equipment for safety protection. [0003] With the continuous application of security equipment in the laboratory, it is found in the actual use process that there is no safety protection equipment for the pipe opening of the lab...
