Hand pinching preventing cabinet door opening and closing mechanism of bed pan cleaning machine

Abstract

The invention discloses a hand pinching preventing cabinet door opening and closing mechanism of a bed pan cleaning machine. The hand pinching preventing cabinet door opening and closing mechanism comprises an electric push rod, a rotating rod, a contact plate, an extension spring, a microswitch installing plate, a first microswitch and a second microswitch. The top end of the electric push rod is connected with a door connecting piece, the other end of the door connecting piece is connected with a door through a door rotating shaft, and the tail end of the electric push rod is hinged to the rotating rod. One end of the rotating rod is hinged to a rack, the contact plate is fixed to the other end of the rotating rod, and the microswitch installing plate is fixed to the part, corresponding to the other end of the rotating rod, of the rack. One end of the extension spring is fixed to the rotating rod, and the other end of the extension spring is connected to the bottom of the rack. The hand pinching preventing cabinet door opening and closing mechanism is simple, compact, low in production cost, small in occupied space and good in stability. The mechanical hand pinching preventing function is achieved, and serious potential safety hazards generated due to the failure of electrical components are avoided. Meanwhile, deformation of the mechanism due to the external force factor is avoided, and the service life of the mechanism is prolonged.

Description

technical field [0001] The invention relates to a cabinet door locking mechanism of a cleaning device, more specifically, to a cabinet door switch mechanism suitable for a bedpan cleaning machine with an anti-pinching function that can prevent hands from being pinched, and belongs to the technical field of medical equipment . Background technique [0002] Medical cleaning equipment usually uses high-pressure water in the cleaning chamber to flush the medical devices placed in the chamber body. In its cleaning working state, the requirements for locking and sealing after the equipment cabinet door is closed are relatively high. In addition to general-purpose medical cleaning machines, there are also medical cleaning machines specially used for cleaning a certain type of medical equipment, such as bedpan cleaning machines specially designed for cleaning bedpans used by hospital patients. [0003] At present, the cabinet door switch mechanism of the existing bedpan cleaning ma...

Problems solved by technology

In the process of use, a uniform multi-link rigid hinge connection is used, powered by an electric push rod, and the rigidity of the entire mechanism is good, but due to the rigid connection, if the control is not good, it will cause excessive force on the transmission link and cause problems. deformation, which easily damages the entire transmission link, making subsequent door opening and closing operations difficult to perform normally, which affects the normal use of the equipment; at the same time, the bedpan cleaning machine is rigidly driven by the electric push rod to drive the transmission link in the process of closing the door. The transmission process cannot be reversed, and it is easy to pinch the hand, threatening the personal safety of the user
