Induction type intelligent door closing method for chemical reagent storage cabinet and chemical reagent storage cabinet

Abstract

The invention discloses an induction type intelligent door closing method for a chemical reagent storage cabinet and the chemical reagent storage cabinet. The induction type intelligent door closing method comprises the following step of judging whether a storage cabinet door is in a closing state or not through a pair of opposite type photoelectric sensors, wherein a storage cabinet closing working principle is as follows: a door closing signal is received by inductive sensors (3) at the lower end of the storage cabinet and is then sent to a main controller (2) at the upper end of the cabinetdoor by analyzing the validity of the signal, the main controller (2) controls a cabinet door drive motor connected with the cabinet door, the motor drives the cabinet door to rotate to a closed position, and electromagnets (1) on the cabinet door are attracted to realize automatic closing of the cabinet door. The induction type intelligent door closing method is relatively simple to operate, aims at overcoming the deficiencies of cabinet door closing of the storage cabinet, achieves the effect of freeing hands by detecting whether a pin exists or not as a signal source for door closing and sending a door closing command, brings a user great convenience, is relatively low in cost, strong in practicability and simple to mount, satisfies operation instantaneity and avoids closing missing ofthe cabinet door of the storage cabinet to cause a certain economic loss.

Description

technical field [0001] The invention relates to the technical field of storage cabinets, in particular to an inductive intelligent door closing method for a chemical reagent storage cabinet and a chemical reagent storage cabinet. Background technique [0002] At present, there are several methods for controlling the closing of the storage cabinet door: [0003] One, after opening the door, it needs to be pushed to the original position by hand to close it. Most of the doors used in people's daily life are fixed and connected by ordinary hinges or hinges, which is not only cumbersome and lacks humanized design, but also prone to failure of the door to close or rebound due to insufficient thrust or excessive force, and easy As a result, the items stored in the display cabinet are not closed or rebound, which will result in poor storage effect. [0004] Its two, a kind of is automatic door closing mechanism, and it all is torsion spring, cam spring or torsion spring lever etc...

AI Technical Summary

Problems solved by technology

[0006] After the door is opened, push it to the original position by hand to close it, which is not only troublesome, but also lacks humanized design, and it is easy to cause the door to not close due to insufficient thrust or excessive force

[0007] Automatic door closing mechanism, generally this kind of automatic structure has complex structure, easy aging of spring, short service life, etc., which is easy to cause complicated installation and high cost, and does not meet the needs of low cost and high efficiency

[0008] The general intelligent door closing system needs to be controlled by the terminal and the operation process is relatively complicated, and the cost investment is relatively large
