TECHNICAL FIELD
[0001] The utility model belongs to toner cartridge powder outlet equipment technical field of printer / copying machine, especially related to a toner cartridge structure applied to printer and copying machine. BACKGROUND
[0002] The toner cartridge for the image forming apparatus has a long toner cartridge and a powder guide, the toner cartridge is used for storing toner, and the powder guide is arranged at the front end of the toner cartridge, the powder guide has a powder outlet for the toner in the toner cartridge to be discharged. The toner cartridge is generally arranged horizontally on the image forming apparatus such as a copying machine or a printer, in order to enable the toner to be smoothly discharged from the toner cartridge to the image forming apparatus through the powder outlet, the inner wall of the toner cartridge is provided with a spiral rib, when in use, the toner cartridge is driven to rotate, and the toner in the toner cartridge can be pushed by the rib to move to the powder outlet of the powder guide and be discharged.
[0003] The existing toner cartridge product of the printer and the copying machine has no powder stirring rod in the inside, so a spiral rib is designed on the toner cartridge, and different depths and shapes of the rib can lead to different powder discharge rates, which can affect the printing speed and even cause the machine to report errors and other problems, in addition, the structural characteristics of the existing toner cartridge can cause the toner to be discharged not smoothly, and the toner cartridge cannot be refilled for repeated use, so it is necessary to develop a toner cartridge to solve the above problems. INVENTION CONTENTS
[0004] To solve the above problems, the utility model adopts the following technical scheme:
[0005] A toner cartridge structure applied to a printer and a copying machine, comprising a cartridge main body, a first cover body, a second cover body and a connecting frame, characterized in that the connecting frame is nested at one end of the cartridge main body, and the second cover body is screwed on the cartridge main body to reinforce the assembly; the first cover body is screwed on the other side of the cartridge main body; the side of the cartridge main body with the first cover body screwed thereon is provided with a refilling hole; and the cartridge main body is integrally formed with an inwardly recessed thread rib.
[0006] Preferably, the thread rib on the cartridge main body is designed as a double-layer thread, and has two sections, namely a first thread rib and a second thread rib.
[0007] Preferably, the thread rib is designed as a flat-angle thread.
[0008] Preferably, the second thread rib is formed on a protruding part of the cartridge main body.
[0009] Preferably, the protruding part is designed as an inclined structure, and the inclination angle in the plane is between 40° and 50°.
[0010] Preferably, the bottom of the powder cylinder body is octagonal in shape.
[0011] Preferably, the thread of the powder cylinder body screwed onto the first cover is designed as a reverse thread.
[0012] Compared to existing technologies, the advantages of this utility model are as follows: The utility model has a reasonable and simple structure. Through detailed design, it can be reused. This advantage is reflected in the fact that a toner filling hole is provided on one side of the toner cartridge body. When the toner in the toner cartridge body is used up, the user does not need to replace the whole body. He only needs to remove the first cover and unscrew it to add toner and continue to use it. This design increases the service life and reduces the cost of use to a certain extent. In addition, the octagonal bottom of the toner cartridge body, the flat-angle thread design of the spiral rib, and the oblique structure design of the protrusion can make the toner dispensing smoother during use. Compared with the traditional structure with rounded or semi-circular edges, the octagonal and flat-angle design of this utility model can greatly reduce the toner deposition problem that exists in the whole round edge design. Because the octagon has more corners, and all corners are obtuse angles, toner is not easy to adhere and accumulate. Attached Figure Description

[0014] Figure 2 This is an exploded view of the present invention.
[0015] Figure 3 This is a schematic diagram of the structure of the powder cylinder body of the utility model.
[0016] Figure 4 This is a schematic diagram of the structure of a traditional powder cartridge according to this utility model. Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] like Figures 1 to 3 As shown, this utility model is a toner cartridge structure for printers and copiers, mainly composed of a toner cartridge body 1, a first cover 2, a second cover 3, and a connecting frame 4.
[0019] The connecting frame 4 is directly sleeved on the left side of the powder cartridge body 1, and the installation position needs to be reinforced and limited by screwing the second cover 3, wherein both ends of the powder cartridge body 1 are designed and formed with threaded lines 14, and the threaded line 14 screwed with the first cover 2 is designed as a reverse threaded line, so that the friction force is increased and the safety is improved, and the loosening of the screwed first cover 2 is avoided, so that the powder leakage of the powder filling hole 10 of the cover is avoided.
[0020] In addition, it is worth noting that the powder cartridge body 1 is integrally formed with an inward threaded rib 11, and the threaded rib 11 is designed as a double-layer threaded line, and has two sections, namely a first threaded rib 110 and a second threaded rib 111, both of which are designed as flat angle threads, wherein the second threaded rib 111 is formed on the protruding portion 12 of the powder cartridge body 1, and the design function is to increase the overall strength of the utility model, so that the thin-walled barrel of the utility model made of plastic has better durability, and the powder can be discharged more smoothly in cooperation with the protruding portion 12 designed as an inclined structure and the barrel bottom 13 designed as an octagonal shape. For details, please refer to Figure 4 The octagonal and flat angle design of the utility model can greatly reduce the toner deposition problem existing in the whole circular edge design, because the octagonal shape has more corners, and all the corners are obtuse angles, so that the toner is not easy to adhere and accumulate.
