Abstract
Description
Technical Field
[0001] This utility model relates to the field of printer repair technology, and in particular to a tool for disassembling printer toner cartridge pins. Background Technology
[0002] A printer is a device that converts digital documents or images into paper output. The toner cartridge is the core component of a laser printer, responsible for transferring toner onto the paper, directly affecting print quality and cost. In printer maintenance, it is sometimes necessary to remove the toner cartridge for maintenance or replacement.
[0003] In the current technology, most toner cartridges are connected using pins instead of metal screws. The pins are embedded in organic plastic and are difficult to remove, making disassembly cumbersome. The pins are also close to the toner cartridge, making it difficult to remove them with pliers, screwdrivers, or other similar tools. Furthermore, removing the pins can easily damage the toner cartridge casing, affecting the maintenance and use of the toner cartridge. Utility Model Content
[0004] The purpose of this invention is to provide a tool for disassembling printer toner cartridge pins, which can solve the problems mentioned in the background art.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a tool for disassembling printer toner cartridge pins, comprising a screw: A clamping assembly is installed at the lower end of the screw and is used to engage with the inside of the pin; The clamping assembly includes: A clamping block is fixedly installed at the lower end of the screw. A lead screw is rotatably connected to the center of the clamping block, and a pressing block is rotatably connected to the outside of the lead screw. A push rod is slidably connected to the lower end of the clamping block. A locking block is fixedly installed on the side of the push rod away from the central axis, and a rubber pad is adhered to the side of the locking block away from the central axis.
[0006] By adopting the above technical solution, rotating the lead screw drives the pressing block to slide down, thereby pushing the push rod and the locking block to slide, so that the rubber pad on the locking block fits against the inner wall of the pin, thereby achieving the locking of the pin.
[0007] A further feature of this invention includes: A drive component, which is installed inside the clamping component.
[0008] The driving component includes: A first bevel gear is fixedly installed on the upper outer side of the lead screw. A second bevel gear meshes with the front end of the first bevel gear. A rotating rod is fixedly installed on the front end of the second bevel gear. A sliding rod is fixedly installed inside the clamping block on the side of the locking block. A slider is slidably connected to the outside of the sliding rod. A spring is provided between the slider and the clamping block. The side of the slider near the central axis is welded to the locking block.
[0009] By adopting the above technical solution, the spring pushes the slider to slide on the outside of the slide bar, and the slider slides, causing the locking block to slide and slide into the clamping block.
[0010] A further feature of this invention includes: A pull-out assembly, mounted on the outside of the screw, is used to pull out the pin.
[0011] The pull-out assembly includes: A movable ring is slidably connected to the outside of the screw. A locking nut is threadedly connected to the upper end of the movable ring on the outside of the screw. A limit ring is rotatably connected to the outside of the movable ring. Support rods are fixedly installed on the left and right sides of the limit ring. A pad is fixedly installed at the lower end of the support rod.
[0012] By adopting the above technical solution, rotating the locking nut makes the locking nut fit with the movable ring, and the pad fits with the toner cartridge structure. As the locking nut rotates, the reaction force on the screw drives the screw to rise, thereby driving the clamping assembly to rise and pull out the pin.
[0013] A further feature of this invention includes: Wear-resistant components, which are installed inside the drawing assembly, are used to reduce wear during the use of the drawing assembly. The wear-resistant component includes: A slot is formed on the outer side of the upper end of the movable ring, and a movable block is rotatably connected inside the slot. A ball bearing is rotatably connected to the inner side of the upper end of the movable ring.
[0014] By adopting the above technical solution, the movable block fits into the locking nut, rotates with the locking nut, and drives the ball bearings to rotate, reducing wear between the locking nut and the movable ring.
[0015] The beneficial effects of this utility model are: The locking assembly of this utility model uses a locking block and a clamping block to cooperate, which facilitates locking of the pin and pins of different inner diameters, making it easier to remove the pins later. At the same time, the spring and the slider cooperate to drive the locking block into the clamping block, preventing the locking block from obstructing the clamping block from being placed into the next pin to be removed.
[0016] The pull-out assembly of this utility model uses a movable ring and a locking nut to facilitate the removal of the pin without damaging the pin and the toner cartridge structure, thus facilitating the recycling of the pin and the toner cartridge. At the same time, the wear-resistant component uses a ball bearing and a movable block to reduce wear when the locking nut and the movable ring rotate in contact, while ensuring the stability of the pull-out assembly during use.

[0020] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0021] Reference Figure 1-4A tool for disassembling printer toner cartridge pins includes a screw 1, a clamping assembly 2, a driving assembly 3, a pulling assembly 4, and a wear-resistant assembly 5. The clamping assembly 2 is installed at the lower end of the screw 1 and is used to engage the pin. The driving assembly 3 is installed inside the clamping assembly 2. The pulling assembly 4 is installed on the outside of the screw 1 and is used to pull out the pin. The wear-resistant assembly 5 is installed inside the pulling assembly 4 and is used to reduce wear on the pulling assembly 4 during use.
[0022] Reference Figure 1 , Figure 2 and Figure 3 The clamping assembly 2 includes: a clamping block 201 fixedly installed at the lower end of the screw 1; a lead screw 202 rotatably connected to the center of the clamping block 201; a pressing block 203 rotatably connected to the outside of the lead screw 202; a push rod 204 slidably connected to the lower end of the clamping block 201; a locking block 205 fixedly installed on the side of the push rod 204 away from the central axis; and a rubber pad 206 adhered to the side of the locking block 205 away from the central axis. The driving assembly 3 includes: a first bevel gear 301 fixedly installed at the upper end of the outside of the lead screw 202; a second bevel gear 302 meshing with the front end of the first bevel gear 301; a rotating rod 303 fixedly installed at the front end of the second bevel gear 302; a sliding rod 304 fixedly installed inside the clamping block 201 on the side of the locking block 205; a slider 305 slidably connected to the outside of the sliding rod 304; a spring 306 between the slider 305 and the clamping block 201; and the side of the slider 305 near the central axis welded to the locking block 205.
[0023] In this invention, when removing the pin, the locking block 201 is inserted into the pin. Then, the rotating rod 303 is rotated, causing the second bevel gear 302 to rotate. The second bevel gear 302 meshes with the first bevel gear 301, thereby causing the first bevel gear 301 to rotate. The lead screw 202 rotates synchronously with the first bevel gear 301. As the lead screw 202 rotates, it causes the pressing block 203 to slide down. The lower end of the pressing block 203 has an arc-shaped design. As the pressing block 203 slides down, the pressing push rod 204 slides outwards, and the sliding push rod 204 drives the locking block 2... 05 slides outward, locking block 205 slides so that rubber pad 206 is tightly attached to the inner wall of the pin, which is convenient for locking the pin. It is also convenient for locking pins with different inner diameters, which is convenient for subsequent removal of the pin. When locking block 205 slides, it simultaneously drives slider 305 to slide on slide rod 304 and compresses spring 306. When the pin is removed and the pressing block 203 is rotated to reset, spring 306 resets simultaneously and pushes slider 305 to slide, thereby driving locking block 205 to slide into clamping block 201, so as to prevent locking block 205 from obstructing clamping block 201 from being placed into the next pin to be removed.
[0024] Reference Figure 1 and Figure 4The pulling assembly 4 includes: a movable ring 401 slidably connected to the outside of the screw 1; a locking nut 402 threadedly connected to the upper end of the movable ring 401 on the outside of the screw 1; a limit ring 403 rotatably connected to the outside of the movable ring 401; support rods 404 fixedly installed on the left and right sides of the limit ring 403; and pads 405 fixedly installed at the lower end of the support rods 404. The wear-resistant assembly 5 includes: a slot 501 opened on the outer side of the upper end of the movable ring 401; a movable block 502 rotatably connected inside the slot 501; and a ball bearing 503 rotatably connected to the inner side of the upper end of the movable ring 401.
[0025] In this invention, after the clamping component 2 is engaged with the pin, the movable ring 401 slides on the screw 1, causing the pad 405 on the support rod 404 to fit against the toner cartridge structure. The pad 405 is made of rubber, which facilitates a tighter fit with the toner cartridge structure. Simultaneously, the limiting ring 403 is rotatably connected to the movable ring 401, allowing the position of the support rod 404 to be adjusted according to the toner cartridge structure to find a suitable support point. Then, the locking nut 402 is tightened, causing it to spiral down until it fits against the movable block 502. Tightening the locking nut 402 again prevents the pad 405 from sliding down due to its fit against the toner cartridge structure, thus applying a reaction force to the screw 1. The screw 1 slides upward due to the screwing action. Since the locking component 2 is tightly locked to the pin, the upward movement of the screw 1 causes the locking component 2 to slide upward, which in turn causes the pin to slide upward, thus enabling the pin to be pulled out. This facilitates the removal of the pin without damaging the pin and the toner cartridge structure, making it easy to recycle the pin and the toner cartridge. When the locking nut 402 rotates in contact with the movable block 502, the movable block 502 rotates inside the slot 501, achieving a rotational connection with the movable ring 401. At the same time, the movable block 502 is tightly attached to the locking nut 402 and rotates with the locking nut 402, synchronously driving the ball 503 to rotate inside the movable ring 401. This reduces wear when the locking nut 402 and the movable ring 401 rotate in contact, while ensuring the stability of the pulling component 4 during use.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
