Pulling and lifting type storehouse opening device for the printer

Abstract

The invention relates to a push-lift bin-opening structure for a printer, which consists of a J-shaped bin-opening key, a bin-opening key shaft which is a 'GU' shape (like a Chinese character), an S-shaped bin-opening key frame, a protection elastic piece and an installation bottom seat arranged on the back surface of a bin cover; the integration is arranged at the opening of one side of the bin cover of the printer; the manual key block of the J-shaped bin-opening key is arranged on the external surface of the bin cover; the bin-opening key frame is fixed on an installation column; a bend-shaped lever block pierces the opening and is arranged on the lower part of the bin cover and axially arranged on the bin-opening key frame; when the manual key block is adopted for pushing ahead, the bend-shaped lever block is deflected to drive a convex buckle at the end part to press downwards and drives a locking shaft handle synchronously deflected and pressed downwards; a paper rolling shaft is released on a frame core and the cover is opened by manual lifting after the bin cover is unlocked. The manual push-lift bin-opening type can effectively avoid the situations such as no-reliability, no-safety and affecting the service life of the printer, etc. caused by sudden opening of the bin cover, printing intermitting, data lost and invalidation of spring, etc. The invention has the advantages of simple structure, convenient application, reliable and safety operation.

Description

technical field [0001] The invention relates to a printer bin-opening mechanism, in particular to a push-and-lift type bin-opening mechanism for a printer which is beneficial to improving working reliability and safety. Background technique [0002] At present, the paper loading mode of the micro printer is usually divided into two types: the automatic paper feeding mode and the easy paper loading mode according to the structure of the printer core. In the automatic paper feeding mode, the rubber shaft used to drive the roll paper, also known as the roll paper shaft, is fixed on the core. The entire core structure cannot be disassembled during the working process. The paper core is inserted into the paper inlet, and the transmission is driven by the control motor; in the easy paper loading mode, the roller paper shaft is fixed on the inner side of the cover, and the cover must be opened when loading paper, and the roll paper shaft is separated from the printer core and put i...

Problems solved by technology

But its fly in the ointment is that it is easy to cause printing out of control

Since the control key is pressed and opened, if the control key is accidentally touched during the work process, the cover will accidentally open, resulting in a sudden interruption of printing and loss of part of the printed data. Therefore, the work is safe and reliable. In addition, because the power of the cover action mainly comes from the spring, and the effective service life of the spring is limited, spring fatigue and poor elasticity are prone to occur during the working process, which affects the action of the cover, thus affecting the normal work and overall performance of the printer. machine life
