Printer uncovering structure

Abstract

The invention provides a printer uncovering structure. The printer uncovering structure comprises an upper shell assembly. An uncovering poking block and an uncovering rotary shaft are rotationally installed on the upper shell assembly. A latch hook is installed on the uncovering rotary shaft. The uncovering rotary shaft and the uncovering poking block are provided with meshed clamping teeth. When poked, the uncovering poking block drives the uncovering rotary shaft to rotate through the clamping teeth, so that the latch hook is opened. The upper shell assembly is further provided with a reset mechanism. The uncovering poking block of the printer uncovering structure conducts meshing steering during opening rotation through the clamping teeth of the uncovering poking block and the clamping teeth of the uncovering rotary shaft. Assembly of the uncovering structure in a small space is achieved in a clamping tooth mashing mode, so that a product is smaller and more portable.

Description

technical field [0001] The invention belongs to the technical field of printers, and in particular relates to a printer cover opening structure. Background technique [0002] Label printer is a device that prints barcode, two-dimensional code, graphics, text and other image information on labels by means of thermal and thermal transfer printing. It is widely used in POS terminal systems, banking systems, medical instruments and other fields. [0003] In traditional printers, the shift block that drives the upper casing to open is usually installed through a torsion spring structure, which is inconvenient to assemble and low in production efficiency. At the same time, the opening structure requires a high space for the upper casing. If the space is too small, it cannot be installed, and if the space is too large, it will increase Printer size. In order to ensure that the printer can only print when it is closed, the detection switch is usually set in the positive direction o...

Problems solved by technology

[0003] In traditional printers, the shift block that drives the upper casing to open is usually installed through a torsion spring structure, which is inconvenient to assemble and low in production efficiency. At the same time, the opening structure requires a high space for the upper casing. If the space is too small, it cannot be installed, and if the space is too large, it will increase Printer size

In order to ensure that the printer can only print when it is closed, the detection switch is usually set in the positive direction of the upper and lower shells in the prior art. Due to the problem of the setting position, the detection switch has been detected and can be printed when the upper shell is not fully closed, so During the printing process, the upper case may pop open suddenly or the printing is not clear, etc.

In addition, the shell and the upper cover of the movement are directly connected by screws, and there is a risk of scrapping or reassembly due to lock deviation

The limit of the rotating shaft in the traditional cover opening structure is realized by the E-type clamp spring, which is cumbersome to assemble
