Mechanical pressure sensing and locking safety device

Abstract

The invention discloses a mechanical pressure sensing and locking safety device which comprises an inductive head, a locking mechanism and a guide sleeve. Two ends of the guide sleeve are respectively provided with a guide hole, a latch rod is inserted into the guide sleeve through the guide holes, the inductive head is connected to the guide sleeve and matched with the guide sleeve to form a mounting space, the locking mechanism is arranged in the mounting space and connected with the inductive head and the latch rod, and the inductive head and the locking mechanism control axial locking and unlocking of the latch rod in a matched manner. The mechanical pressure sensing and locking safety device has the advantages that the device is compact in structure, reliable in action execution, convenient to mount, applicable to occasions with sanitary and anti-explosion requirements and passive sites, high in safety and sensitive in response, and can be automatically locked and unlocked.

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 are stored in plastic film bags, metered and dispensed, and placed upright in storage equipment boxes, during the process of replacing and inspecting plastic film bags, or in the process of tank liquid and dispensing, 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 passive, and there is a lack of a safe passive automatic locking safety device suitable for passive environments. The staff often open the storage equipment box door due to misjudgment, causing the plastic film with a lot of liquid inside to rupture under the internal hydraulic pressure, resulting in an accident of bag rupture and liquid overflow. Contents of the invention [0003] Th...
