Description

Technical Field

[0001] The utility model relates to a pivotally connected selenium drum, in particular to a pivotally connected selenium drum, belonging to the technical field of printers. Background Art

[0002] The toner cartridge 1 is an important part of the laser printer. It is mainly composed of a photosensitive drum, a toner bin, etc. Its function is to absorb toner through static electricity and then transfer the toner to the printing paper to form text or images. The quality of the toner cartridge 1 will directly affect the printing effect and clarity.

[0003] The existing toner cartridge 1 is installed inside the printer, and is basically snap-connected. When the toner inside the toner cartridge 1 is used up, the old toner cartridge 1 needs to be taken out of the printer, and then new toner is added to the toner cartridge 1. After the addition is completed, the toner cartridge 1 is installed inside the printer again. Because the toner cartridge 1 is full of new toner, toner leakage is likely to occur during the installation process, and the installer's hands are covered with toner, which is difficult to clean.

[0004] Therefore, a pivotally connected toner cartridge is proposed to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a pivotally connected toner cartridge, which drives a connecting block to slide in a U-shaped groove, so that one end of a limiting rod slides on a curved surface of a truncated table. When one end of the limiting rod moves to one end of the truncated table, the limiting rod and one end of the truncated table collide with each other to form a limit, thereby preventing the connecting block from sliding out of the U-shaped groove. The toner cartridge is rotated to drive the connecting block and the connecting column, so that the connecting column rotates inside the damper, the angle of the toner cartridge is adjusted, and then new powder is added to the toner cartridge through the powder inlet hole.

[0006] In order to achieve the above-mentioned purpose, the main technical scheme adopted by the utility model includes: comprising a toner cartridge and a printer body, dampers are fixedly connected on both sides of the printer body, connecting columns are fixedly connected inside the dampers, a U-shaped groove is provided inside the connecting columns, a limiting column is fixedly connected inside the U-shaped groove, a frustum is fixedly connected to the top of the limiting column, connecting blocks slidably connected to the U-shaped groove are fixedly connected on both sides of the toner cartridge, a cavity is provided inside the connecting block, limiting rods are slidably connected on both sides of the cavity, the limiting rods correspond to the frustum, and a powder inlet hole is provided at one end of the upper surface of the toner cartridge.

[0007] Preferably, a resistance spring is provided between the inner wall of the cavity and the limiting rod.

[0008] Preferably, opposite ends of the two limit rods are fixedly connected with a trapezoid, and the trapezoid corresponds to the truncated cone.

[0009] Preferably, the outer wall of the limiting column is slidably connected with a second frustum, the second frustum is opposite to the inclined surface of the first frustum, and the side of the trapezoid close to the second frustum is an inclined surface.

[0010] Preferably, a waste powder outlet is provided on the outer surface of one end of the toner cartridge away from the powder inlet hole.

[0011] Preferably, a sealing plate is slidably connected to the outer wall of the toner cartridge close to the powder inlet, and a sealing plug is threadedly connected to the inner wall of the waste powder outlet.

[0012] Preferably, a sliding block is fixedly connected to one side of the sealing plate, the sliding block extends into the interior of the toner cartridge, and a return spring is provided between the sliding block and the toner cartridge.

[0013] The utility model has at least the following beneficial effects:

[0014] 1. The toner cartridge drives the connecting block to slide in the U-shaped groove, so that one end of the limiting rod slides on the curved surface of the frustum. When one end of the limiting rod moves to one end of the frustum, the limiting rod and one end of the frustum collide with each other to form a limit to prevent the connecting block from sliding out of the U-shaped groove. Rotate the toner cartridge to drive the connecting block and the connecting column, so that the connecting column rotates inside the damper, adjust the angle of the toner cartridge, and then add new powder into the toner cartridge through the powder inlet hole.

[0015] 2. Through the provided truncated cone 2, when the trapezoid moves in the direction of truncated cone 2, the inclined surface of the trapezoid and a section of the outer wall of truncated cone 2 are in conflict with each other, so that the trapezoid drives the limit rod to move to both sides. When one end of the trapezoid moves to the curved surface of truncated cone 2, the two trapezoids clamp truncated cone 2 under the action of the conflicting spring. The limit rod can drive truncated cone 2 to slide on the outer wall of the limit column by moving up and down. When truncated cone 2 is driven to move and conflict with truncated cone 1, one end of the trapezoid slides to the curved surface of truncated cone 1 along the curved surface of truncated cone 2, so that the toner cartridge drives the connecting block to slide out from the inside of the U-shaped groove.

DETAILED DESCRIPTION

[0023] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] like Figure 1-Figure 5 As shown, a pivotally connected toner cartridge provided in this embodiment includes a toner cartridge 1 and a printer body 2. Dampers 3 are fixedly connected to both sides of the printer body 2. A connecting column 4 is fixedly connected to the inside of the damper 3. The connecting column 4 can rotate inside the damper 3, but the damper 3 prevents the connecting column 4 from rotating without external force, thereby increasing the resistance of the connecting column 4 to rotation inside the damper 3. A U-shaped groove 5 is provided inside the connecting column 4. A limiting column 6 is fixedly connected to the inside of the U-shaped groove 5. A round table 7 is fixedly connected to the top of the limiting column 6. The round table 7 is close to the limiting column The diameter of one end of 6 is larger than the diameter of the other end. Both sides of the toner cartridge 1 are fixedly connected with connecting blocks 8 that are slidably connected to the U-shaped groove 5. A cavity 9 is opened inside the connecting block 8. Both sides of the cavity 9 are slidably connected with limiting rods 10. The limiting rods 10 correspond to the truncated table 7. When the connecting block 8 slides into the U-shaped groove 5, the two ends of the limiting rod 10 conflict with the inclined surface of the truncated table 7, so that the limiting rod 10 slides along the inclined surface of the truncated table 7. Finally, the two ends of the limiting rod 10 slide with the other end of the truncated table, and a limiting effect is played through the conflict between one end of the truncated table 7 and the limiting rod 10.

[0025] Further, such as Figure 1-Figure 5 As shown, a resistance spring 12 is provided between the inner wall of the cavity 9 and the limit rod 10. After the resistance spring 12 is used to break the resistance between the limit rod 10 and the truncated table 7, the limit rod 10 can be automatically moved so that one end of the limit rod 10 can directly resist one end of the truncated table 7.

[0026] Further, if Figure 1-Figure 5 As shown, the opposite ends of the two limit rods 10 are fixedly connected with a trapezoid 13, the trapezoid 13 corresponds to the truncated cone 7, and the inclined surface of the trapezoid 13 is slidably connected to the curved surface side of the truncated cone 7, which can reduce the friction between the trapezoid 13 and the truncated cone 7.

[0027] Among them, Figure 1-Figure 5 As shown, the outer wall of the limiting column 6 is slidably connected with a truncated cone 2 14, and the truncated cone 2 14 is opposite to the inclined surface of the truncated cone 1 7, and the side of the trapezoid 13 close to the truncated cone 2 14 is an inclined surface. When the trapezoid 13 is located between the truncated cone 1 7 and the truncated cone 2 14, the trapezoid 13 can be moved in the direction of the truncated cone 2 14 so that the inclined surface of the trapezoid 13 and a section of the outer wall of the truncated cone 2 14 conflict with each other, so that the trapezoid 13 drives the limiting rod 10 to move to both sides. When one end of the trapezoid 13 moves to the curved surface of the truncated cone 2 14, the two trapezoids 13 clamp the truncated cone 2 14 under the action of the conflicting spring 12, and the limiting rod 10 moves up and down to drive the truncated cone 2 14 to slide on the outer wall of the limiting column 6. When driving the truncated cone 2 14 to move to conflict with the truncated cone 1 7, one end of the trapezoid 13 slides along the curved surface of the truncated cone 2 14 to the curved surface of the truncated cone 1 7, so that the toner cartridge 1 drives the connecting block 8 to slide out of the U-shaped groove 5.

[0028] Among them, Figure 1-Figure 5 As shown, a powder inlet hole 11 is provided at one end of the upper surface of the toner cartridge 1, through which new toner can be added. A waste toner outlet 15 is provided on the outer surface of one end of the toner cartridge 1 away from the powder inlet hole 11, for pouring out waste toner.

[0029] Further, such as Figure 1-Figure 5 As shown, a sealing plate 16 is slidably connected to the outer wall of the toner cartridge 1 near the powder inlet hole 11, and the powder inlet hole 11 is sealed by the sealing plate 16 to prevent the toner inside the toner cartridge 1 from scattering. The powder inlet hole 11 is opened by sliding the sealing plate 16 to facilitate adding new toner. The inner wall of the waste powder port 15 is threadedly connected with a sealing plug 17, and the waste powder port 15 is sealed by the sealing plug 17. The waste powder port 15 can be opened by rotating the sealing plug 17.

[0030] Further, if Figure 1-Figure 5 As shown, a sliding block 18 is fixedly connected to one side of the sealing plate 16, and the sliding block 18 extends to the inside of the toner cartridge 1, and a reset spring 19 is provided between the sliding block 18 and the toner cartridge 1. The reset spring 19 resists the sliding block 18, so that the sliding block 18 and the sealing plate 16 remain stationary without external force, and after the sealing plate 16 is pushed to open the powder inlet 11, the sealing plate 16 can be automatically reset under the action of the reset spring 19.

[0031] like Figure 1-Figure 5As shown, the principle of the pivotally connected toner cartridge provided in this embodiment is as follows: the toner cartridge 1 drives the connecting block 8 to slide in the U-shaped groove 5, so that the inclined surface of the trapezoid 13 slides on the curved surface of the truncated cone 7, so that the trapezoid 13 drives the limiting rod 10 to slide in the cavity 9, and squeezes the resistance spring 12 at the same time. When the trapezoid 13 moves to the lower bottom surface of the truncated cone 7, the limiting rod 10 and the trapezoid 13 are pushed to move toward each other under the resistance of the resistance spring 12 to form a limit. The sliding sealing plate 16 drives the sliding block 18 to squeeze the reset spring 19, and the powder inlet 11 is opened to facilitate the addition of new toner.

[0032] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0033] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0034] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field.
