Abstract
Description
Technical Field
[0001] This utility model relates to the field of toner cartridge structure technology, specifically a toner cartridge structure that can reduce costs. Background Technology
[0002] A printer is one of the output devices of a computer, used to print the results of computer processing onto relevant media. There are three indicators to measure the quality of a printer: print resolution, print speed, and noise. Printers require a toner cartridge structure during use. However, existing cost-reducing toner cartridge structures have some shortcomings in use. In order to meet market needs, a cost-reducing toner cartridge structure is required.
[0003] The existing toner cartridge structure is not practical enough in use, and the overall production cost is relatively high. This makes the toner cartridge prone to expansion during continuous printing, and the structure is not simple enough, resulting in poor conductivity. In addition, the assembly steps of the existing toner cartridge structure are cumbersome and inconvenient to operate, which increases the assembly time and further increases the cost of the toner cartridge. Utility Model Content
[0004] The purpose of this utility model is to provide a toner cartridge structure that can reduce costs, so as to solve the problems mentioned in the background art, such as the high overall production cost of the toner cartridge structure and the cumbersome assembly steps that are inconvenient to operate.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cost-reducing toner cartridge structure, comprising a toner cartridge body, a detachable first side cover provided on one end of the surface of the toner cartridge body, a detachable second side cover provided on the surface of the toner cartridge body away from the first side cover, a handle installed on the surface of the toner cartridge body, a bracket installed on the surface of the toner cartridge body, a magnetic roller body provided on the surface of the toner cartridge body, a rotating gear sleeved on one end of the surface of the magnetic roller body, a simple assembly mechanism provided on the inner walls of the first and second side covers, and a cost-reducing mechanism provided on the surfaces of the second side cover and the magnetic roller body.
[0006] Preferably, the simplified assembly mechanism consists of an assembly plate disposed on the inner wall of the first side cover, an assembly rod disposed on the surface of the assembly plate, a positioning sleeve disposed on the inner walls of the first and second side covers, a positioning rod disposed on the surface of the toner cartridge body, and an assembly block disposed on the inner walls of the first and second side covers.
[0007] Preferably, the inner walls of the first side cover and the second side cover are equipped with positioning sleeves, and the surfaces of both ends of the toner cartridge body are equipped with positioning rods. One end of the positioning rod is inserted into the interior of the positioning sleeve and engages with the inner wall of the positioning sleeve. The inner walls of the first side cover and the second side cover are equipped with assembly blocks, and the assembly blocks engage with the surface of the toner cartridge body.
[0008] Preferably, an assembly plate is installed on the inner wall of the first side cover, and an assembly rod is installed on the surface of the assembly plate. One end of the assembly rod is inserted into the interior of the rotating gear and cooperates with the rotating gear.
[0009] Preferably, the cost reduction mechanism includes a conductive sheet disposed on the surface of the second side cover, protective bushings sleeved on both ends of the magnetic roller body, conductive material disposed at both ends of the magnetic roller body, and conductive wire disposed on the surface of the conductive material.
[0010] Preferably, protective bushings are fitted on the surfaces of both ends of the magnetic roller body, conductive materials for conducting electricity are installed on the surfaces of both ends of the magnetic roller body, conductive wires are installed on the surfaces of the conductive materials, and conductive sheets for conducting electricity are installed on the surfaces of the second side cover, with the surfaces of the conductive sheets in contact with the inner wall of the second side cover.
[0011] Compared with the prior art, the beneficial effects of this utility model are: the cost-reducing toner cartridge structure not only saves the production cost of the toner cartridge structure when used, but also solves the problem of expansion caused by continuous printing. The direct conductive method makes the structure of the toner cartridge simpler and the conductivity better. Moreover, it makes the toner cartridge structure easier to assemble and use, saves the assembly time of the toner cartridge structure, and further reduces the cost of the toner cartridge structure.
[0012] 1. By incorporating cost-reduction mechanisms, the size and dimensions of the magnetic roller body are proportionally smaller than those of commonly used magnetic rollers in toner cartridges on the market, resulting in a smaller volume and lower cost for the toner cartridge structure. A protective sleeve covers the surface of the magnetic roller body, reducing the risk of expansion during continuous printing and thus minimizing print quality. This makes the toner cartridge structure more durable and less prone to malfunctions. The conductive material and conductive wires on the surface of the magnetic roller body enhance conductivity. When the second side cover is assembled onto the surface of the toner cartridge body, the conductive material and conductive wires can conduct electricity directly through the conductive sheet, eliminating the need for additional conductive components on the inner wall of the second side cover. This further reduces the cost of the toner cartridge structure, increasing its practicality and achieving cost reduction. This saves on toner cartridge production costs and solves the problem of expansion during continuous printing. The direct conductivity method simplifies the toner cartridge structure and improves conductivity.
[0013] 2. By incorporating a simplified assembly mechanism, the assembly rod is inserted into the rotating gear. When the gear set on the surface of the toner cartridge body drives the rotating gear to rotate, the rotating gear drives the magnetic roller body to rotate on the surface of the toner cartridge body. The rotating gear rotates on the surface of the assembly rod, causing the first side cover to engage with the positioning sleeve and engage with the positioning rod. The assembly block on the inner wall of the first side cover engages with the surface of the toner cartridge body. With the combined action of the positioning sleeve, positioning rod, and assembly block, the first side cover can be positioned and assembled on one end of the toner cartridge body. The user then places the second side cover on the other end of the toner cartridge body, causing the positioning sleeve on the inner wall of the second side cover to engage with the positioning rod on the surface of the toner cartridge body, thus securing the second side cover. This simplified assembly of the toner cartridge structure makes it easier to assemble and use, saves assembly time, and further reduces the cost of the toner cartridge structure.

[0020] The present invention provides a toner cartridge structure that can reduce costs, as shown in the following figure. Figures 1 to 4 As shown, the device includes a toner cartridge body 1, a removable first side cover 11 on one end of the surface of the toner cartridge body 1, a removable second side cover 12 on the surface of the toner cartridge body 1 away from the first side cover 11, a handle 14 mounted on the surface of the toner cartridge body 1, a bracket 15 mounted on the surface of the toner cartridge body 1, a magnetic roller body 13 mounted on the surface of the toner cartridge body 1, and a rotating gear 16 sleeved on one end of the surface of the magnetic roller body 13.
[0021] Furthermore, such as Figure 3 and Figure 4As shown, a simple assembly mechanism 2 is provided on the inner walls of the first side cover 11 and the second side cover 12. The simple assembly mechanism 2 consists of an assembly plate 21 provided on the inner wall of the first side cover 11, an assembly rod 23 provided on the surface of the assembly plate 21, a positioning sleeve 22 provided on the inner walls of the first side cover 11 and the second side cover 12, a positioning rod 24 provided on the surface of the toner cartridge body 1, and an assembly block 25 provided on the inner walls of the first side cover 11 and the second side cover 12. The positioning sleeve 22 is installed on the inner walls of the first side cover 11 and the second side cover 12, and the toner cartridge... Positioning rods 24 are installed on the surfaces of both ends of the cartridge body 1. One end of the positioning rod 24 is inserted into the interior of the positioning sleeve 22 and engages with the inner wall of the positioning sleeve 22. Assembly blocks 25 are installed on the inner walls of the first side cover 11 and the second side cover 12. Assembly blocks 25 engage with the surface of the toner cartridge body 1. Assembly plate 21 is installed on the inner wall of the first side cover 11. Assembly rod 23 is installed on the surface of the assembly plate 21. One end of the assembly rod 23 is inserted into the interior of the rotating gear 16 and engages with the rotating gear 16.
[0022] During implementation, the first side cover 11 drives the inner wall assembly plate 21 and assembly rod 23 to move, so that the assembly rod 23 is inserted into the interior of the rotating gear 16. When the gear set on the surface of the toner cartridge body 1 drives the rotating gear 16 to rotate, the rotating gear 16 can drive the magnetic roller body 13 to rotate on the surface of the toner cartridge body 1. At this time, the rotating gear 16 rotates on the surface of the assembly rod 23, and the first side cover 11 drives the positioning sleeve 22 to lock onto the surface of the positioning rod 24. The assembly block 25 on the inner wall of the first side cover 11 locks onto the surface of the toner cartridge body 1. With the joint cooperation of the positioning sleeve 22, the positioning rod 24 and the assembly block 25, the first side cover 11 can be positioned and assembled on the surface of one end of the toner cartridge body 1. The user then places the second side cover 12 on the surface of the other end of the toner cartridge body 1, so that the positioning sleeve 22 on the inner wall of the second side cover 12 locks onto the surface of the positioning rod 24 on the surface of the toner cartridge body 1, and the second side cover 12 is snapped on and installed to realize the function of simple assembly of the toner cartridge structure.
[0023] Furthermore, such as Figure 3 and Figure 4 As shown, the second side cover 12 and the surface of the magnetic roller body 13 are provided with a cost reduction mechanism 3. The cost reduction mechanism 3 includes a conductive sheet 31 disposed on the surface of the second side cover 12, a protective bushing 32 sleeved on the surfaces of both ends of the magnetic roller body 13, a conductive material 33 disposed on both ends of the magnetic roller body 13, and a conductive wire 34 disposed on the surface of the conductive material 33. The surfaces of both ends of the magnetic roller body 13 are sleeved with protective bushing 32. The surfaces of both ends of the magnetic roller body 13 are provided with conductive material 33 for conducting electricity. The surface of the conductive material 33 is provided with conductive wire 34. The surface of the second side cover 12 is provided with a conductive sheet 31 for conducting electricity. The surface of the conductive sheet 31 is in contact with the inner wall of the second side cover 12.
[0024] In implementation, the size of the magnetic roller body 13 is proportionally smaller than that of commonly used magnetic rollers for toner cartridges on the market, resulting in a smaller volume and lower cost for the toner cartridge structure. The protective bushing 32 is fitted onto the surface of the magnetic roller body 13, which reduces the expansion that affects print quality during continuous printing, making the toner cartridge structure more durable and less prone to failure. At the same time, the conductive material 33 and conductive wire 34 on the surface of the magnetic roller body 13 enhance conductivity during use. When the second side cover 12 is assembled on the surface of the toner cartridge body 1, the conductive material 33 and conductive wire 34 can conduct electricity directly through the conductive sheet 31, eliminating the need for additional conductive components on the inner wall of the second side cover 12. This further reduces the cost of the toner cartridge structure and increases its practicality, thus achieving the goal of reducing the cost of the toner cartridge structure.
[0025] Working Principle: In use, first place the toner cartridge body 1 in the designated position. Because the size of the magnetic roller body 13 is proportionally smaller than that of commonly used magnetic rollers for toner cartridges on the market, its volume is smaller, resulting in a lower cost for the toner cartridge structure. A protective sleeve 32 is fitted onto the surface of the magnetic roller body 13. Under the action of the protective sleeve 32, the magnetic roller body 13 can reduce the problem of expansion during continuous printing, which could affect print quality. This makes the toner cartridge structure more durable and less prone to failure. Simultaneously, the combined action of the conductive material 33 and conductive wire 34 on the surface of the magnetic roller body 13... The roller body 13 has better conductivity during use. When the second side cover 12 is assembled on the surface of the toner cartridge body 1, the conductive material 33 and the conductive wire 34 can conduct electricity directly through the conductive sheet 31. There is no need to use other conductive components on the inner wall of the second side cover 12, which further reduces the cost of the toner cartridge structure during use and makes it more practical. This achieves the function of reducing the cost of the toner cartridge structure, thereby saving the production cost of the toner cartridge structure during use. At the same time, it can solve the problem of expansion caused by continuous printing. The direct conductivity method makes the structure of the toner cartridge simpler and the conductivity better.
[0026] Subsequently, after the magnetic roller body 13 is assembled onto the surface of the bracket 15, the user needs to assemble the first side cover 11 and the second side cover 12 onto the surfaces of both ends of the toner cartridge body 1. The user places the rotating gear 16 onto the surface of the magnetic roller body 13, and then places the first side cover 11 onto the surface of the toner cartridge body 1, causing the first side cover 11 to drive the inner wall assembly plate 21 and assembly rod 23 to move, so that the assembly rod 23 is inserted into the interior of the rotating gear 16. When the gear set on the surface of the toner cartridge body 1 drives the rotating gear 16 to rotate, the rotating gear 16 can drive the magnetic roller body 13 to rotate on the surface of the toner cartridge body 1. At this time, the rotating gear 16 rotates on the surface of the assembly rod 23, and the first side cover 11 drives the positioning sleeve 22 to engage with the positioning rod 24. On the other hand, the assembly clip 25 on the inner wall of the first side cover 11 is attached to the surface of the toner cartridge body 1. With the cooperation of the positioning sleeve 22, the positioning rod 24 and the assembly clip 25, the first side cover 11 can be positioned and assembled on the surface of one end of the toner cartridge body 1. The user then places the second side cover 12 on the surface of the other end of the toner cartridge body 1, so that the positioning sleeve 22 on the inner wall of the second side cover 12 is attached to the surface of the positioning rod 24 on the surface of the toner cartridge body 1, and the second side cover 12 is snapped in place. This achieves the function of easy assembly of the toner cartridge structure, making the toner cartridge structure more convenient to operate during assembly and use, saving the assembly time of the toner cartridge structure, further reducing the cost of the toner cartridge structure, and finally completing the use of the toner cartridge structure.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
