Description

Toner cartridge pull bracket assembly for office equipment pull toner cartridge mechanism

technical field

The invention relates to an accessory for office equipment, in particular to a toner cartridge pulling bracket assembly for a toner cartridge pulling mechanism of office equipment such as a printer, a fax machine and a copier.

Background technique

General office equipment (printers, fax machines, copiers) all print in black and white, that is, use a black toner cartridge for monochrome printing. The printers are used as representatives for discussion below. Traditional monochrome black-and-white printers only need one toner cartridge, so there is no need for any special assembly mechanism to assemble the toner cartridge, as long as a common door or cover structure is opened to facilitate access to the toner cartridge. In recent years, with the emergence of color printers, multi-color printing has become a trend. However, color printers are equipped with a variety of standard color toner cartridges. No matter what color is printed, these standard color powders must be matched However, some users do not need color printing, but only need two or three color printing (such as red-headed documents with red stamps). If you use a color printer, this is undoubtedly a waste. Therefore, to complete two-color printing or three-color printing, you only need to be equipped with two or three toner cartridges of different colors. However, the space occupied by two or three toner cartridges is not small. Opening the shell of the printer will inevitably bring cumbersome operations to the user. If this problem is to be solved, it is necessary to change the traditional way of picking and placing the toner cartridges, that is, to put all the toner cartridges in a shelf similar to a drawer, and the user can take and place the toner cartridges by pulling the shelf, which requires a new design of a drawer. The mechanism that pulls the toner cartridge. In this set of mechanisms, a new set of toner cartridge pulling bracket assembly needs to be newly designed, so as to finally realize the mechanism of pulling the toner cartridge.

Contents of the invention

In view of the requirements of the above new technical structure, the present invention provides a toner cartridge pull bracket assembly for office equipment pull toner cartridge mechanism, that is, all toner cartridges are placed in a shelf similar to a drawer, and users can take and place toner cartridges by pulling the shelf .

In order to achieve the above object, the technical solution adopted by the present invention is: a toner drum pull bracket assembly for office equipment pull toner drum mechanism, characterized in that: the toner drum pull bracket assembly includes a toner drum pull bracket, a paper feeding pressure guide Roller, paper feeding pressure guide roller spring, toner cartridge drawer control rod, toner cartridge drawer lock block and toner cartridge drawer lock block spring, the toner cartridge drawer support is composed of a rectangular large frame and a small box body integrated , several toner drum slots can be set through the baffle in the large rectangular frame, U-shaped raised slots are symmetrically arranged on both side walls of each toner drum slot, and several electrode pin holes are arranged on one of the wall surfaces, On the two side walls of the large rectangular frame, bosses and slideways are symmetrically arranged, a rectangular protrusion is arranged on the top of one of the walls, and a rectangular hole is arranged on the surface of the small box body. There are semi-circular grooves and two short spring shafts at the junction of the small box body, and two positioning grooves and a locking block guide groove are arranged in the box body on the back of the small box body;

The two ends of the upper end surface of the paper feeding pressure guide roller are arc-shaped surfaces, and a semicircular card slot is provided on the plane in the middle of the two ends of the arc-shaped surfaces, and cylinders are symmetrically arranged on both sides; the toner cartridge pull bracket lock The block is L-shaped, with a square hole in the middle, and a raised cross shaft in the U-shaped groove at the upper end;

The paper feeding pressure guide roller is stuck in the semicircle groove on the toner cartridge pulling bracket through two cylinders, the U-shaped end of the paper feeding pressure guide roller spring is stuck in the semicircle groove on the paper feeding pressure guide roller, and Press the paper feeding pressure guide roller, and the two spring rings at the lower end of the paper feeding pressure guide roller spring are respectively set on the two spring short shafts of the toner cartridge pulling bracket. The function of the paper feeding pressure guide roller is to guide the paper along the correct direction. movement to prevent the paper from skewing; the control rod of the toner cartridge pulling bracket is fixed in the two positioning grooves under the toner cartridge pulling bracket through the short shafts at both ends, and the V-shaped surface of the guide handle is placed in the rectangular hole of the small box body. One end of the lock block spring of the drum pull bracket is set on the raised cross shaft of the lock block of the drum pull bracket. In the guide groove, the other end of the lock block spring of the toner cartridge pull bracket pushes to the deepest part of the guide groove of the lock block. A linkage is formed, that is, when the guide handle on the control lever of the toner cartridge pull-out bracket is pressed down, the lock block of the toner cartridge pull-out bracket will be lifted up, and when the guide handle on the control rod of the toner cartridge pull-out bracket is released, the toner cartridge will pull The bracket lock block will return to the original position under the effect of the toner cartridge pull lock block spring.

The beneficial effects produced by the present invention are: adopting this design, the toner cartridge can be loaded for pulling movement, and the mechanism of pulling the toner cartridge is realized. This design is compact in structure, small in size, and easy to install. When the volume of office equipment allows, the structural size of the toner cartridge pull-out bracket can be adjusted accordingly according to special needs, and the number of toner cartridge slots set through the baffle in the large rectangular frame can be increased for convenience. The number of placed toner cartridges can be increased to achieve multi-color simultaneous printing. This design can be widely used in printers, copiers and fax machines.
