Mechanical pressure sensing locking safety device

Abstract

The invention discloses a mechanical pressure sensing locking safety device, which comprises an induction head, a locking mechanism and a guide sleeve; two ends of the guide sleeve respectively form a corresponding guide hole, and a latch rod passes through the guide hole inserted into the guide sleeve; the induction head is connected to the guide sleeve and cooperates with the guide sleeve to form an installation space, and the locking mechanism is arranged in the installation space and connects the induction head and the The latch rod, the induction head and the locking mechanism cooperate to control the axial locking and unlocking of the latch rod. Due to the use of a mechanical pressure sensing locking safety device of the present invention, it has compact structure, reliable execution, convenient installation, and is suitable for occasions with sanitary requirements, passive sites and explosion-proof requirements. High security, responsive, automatic locking and unlocking features.

Description

technical field [0001] The invention relates to a locking safety device, in particular to a mechanical pressure sensing locking safety device. Background technique [0002] At present, for container units that use plastic film bags as storage, measure and dispense solutions, and place them upright in storage equipment boxes, during the process of replacing and inspecting plastic film bags, or in the process of tank liquid and sub-packaging, due to liquid The liquid level of the transparent liquid in the bag is difficult to distinguish with the naked eye, especially in a dangerous environment that needs to be kept passive, there is a lack of a safe passive automatic locking safety device suitable for the passive environment. The staff often opens the door of the storage equipment box due to misjudgment, causing the plastic film with more liquid inside to rupture under the load of the internal hydraulic pressure, resulting in the accident of the bag breaking and overflowing. ...
