Description

Technical Field

[0001] This utility model relates to the field of printer toner cartridge technology, and in particular to a printer toner cartridge that can be quickly disassembled. Background Technology

[0002] A printer drum is a key component of a printer, mainly used to transfer toner onto the printing paper during the printing process. It consists of a photosensitive drum and a toner cartridge containing toner. The photosensitive drum is coated with a photosensitive material. When a printing signal is received, the photosensitive material ionizes, enabling the toner to be adsorbed and released on the surface of the photosensitive drum.

[0003] A patent document with publication number CN221668176U has been disclosed in the prior art. This patent document discloses a printer toner cartridge that can be quickly disassembled. It includes a shell, and fixing blocks are provided on the left and right side walls of the inner cavity of the shell. The opposite side walls of the two sets of fixing blocks are provided with function grooves. The inner cavity of each function groove is provided with a mounting block. The mounting block is concave. This patent document has the ability to facilitate the quick disassembly of the toner cartridge body by setting the shell, fixing blocks and mounting blocks in cooperation, so as to improve the repair efficiency of the staff, save time and improve efficiency.

[0004] The above-mentioned and existing technologies have the following drawbacks: due to the snap-on fixing structure, the snap-on strength may be relatively large, requiring a lot of force to open or fasten it, which is more laborious and time-consuming to operate, resulting in damage to the shell.

[0005] Therefore, a printer toner cartridge that can be quickly disassembled is proposed. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of snap-on fixing structures, which may require significant force to open or fasten, making operation laborious and time-consuming, and potentially damaging the casing. Therefore, this invention proposes a printer toner cartridge that can be quickly disassembled.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a quickly detachable printer toner cartridge, comprising a toner cartridge body, a housing mounted on the surface of the toner cartridge body, a disassembly device provided on the surface of the housing, the disassembly device comprising a fixing ring fixedly connected to the housing, a push rod slidably connected to the surface of the fixing ring, a first spring sleeved on the arc surface of the push rod, the two ends of the first spring being fixedly connected to the fixing ring and the push rod respectively, a conical frame fixedly connected to one end of the push rod, a connecting tube slidably connected to the surface of the conical frame, the connecting... The tube is fixedly connected to the toner cartridge body. Two slide rods are slidably connected to the arc surface of the connecting tube. A second spring is sleeved on the arc surface of each slide rod. The two ends of the second spring are fixedly connected to the connecting tube and the slide rod, respectively. A stop block is fixedly connected to one end of the slide rod. The stop block is engaged with the conical frame. A double cone block is slidably connected to the arc surface of the push rod. A sliding frame is fixedly connected to the surface of the double cone block. The size of the double cone block is adapted to the conical frame. The sliding frame is slidably connected to the fixing ring. A lead screw is threadedly connected to the surface of the sliding frame. The lead screw is threadedly connected to the fixing ring.

[0008] The aforementioned components achieve the following effect: By setting up a disassembly device, and utilizing the cooperation between the fixing ring, push rod, first spring, conical frame, connecting pipe, slide rod, second spring, stop block, double conical block, sliding frame, and lead screw, the housing and toner cartridge body can be quickly and stably installed and disassembled. This avoids the problem that due to the snap-on fixing structure, the snap-on strength may be too large, requiring a lot of force to open or fasten it, making the operation laborious and time-consuming, which could lead to damage to the housing. This improves the convenience of installing and disassembling the toner cartridge body and housing.

[0009] Preferably, an anti-slip pad is fixedly connected to the surface of the sliding frame, and the anti-slip pad is slidably connected to the lead screw.

[0010] The effect achieved by the above components is that the lead screw will move along the anti-slip pad on the sliding frame, and at this time the anti-slip pad can increase the friction between the lead screw and the contact surface of the sliding frame.

[0011] Preferably, one end of the lead screw is fixedly connected to an elastic rope, and the other end of the elastic rope is fixedly connected to a fixing ring.

[0012] The effect achieved by the above components is that the lead screw will drive one end of the elastic rope to move, and at this time the elastic rope can prevent the lead screw from being lost when it loses contact with the sliding frame.

[0013] Preferably, one end of the lead screw is fixedly connected to a pointed cone, which is a stainless steel cone.

[0014] The effect achieved by the above components is that the lead screw will drive the pointed cone to move closer to the fixed ring, at which time the pointed cone can facilitate the lead screw to enter the fixed ring.

[0015] Preferably, one end of the push rod is fixedly connected to a push pad, which is a rubber pad.

[0016] The effect achieved by the above components is that when the push pad on the push rod is pressed towards the fixed ring, the rubber push pad can protect the contact surface between the operator's fingers and the push rod.

[0017] Preferably, a protective pad, which is a sponge pad, is fixedly connected to the surface of the stop block.

[0018] The effect achieved by the above components is that the straight surface of the stop block will cause the protective pad to come into contact with the conical frame. At this time, the protective pad, which is made of sponge material, can protect the contact surface between the straight surface of the stop block and the conical frame.

[0019] Preferably, the inclined surface of the stop block is rotatably connected to a plurality of ball bearings, and the plurality of ball bearings are evenly distributed on the surface of the stop block.

[0020] The effect achieved by the above components is that the arc surface of the conical frame will cause the ball bearings on the inclined surface of the stop block to roll, and at this time the ball bearings can reduce the friction between the inclined surface of the stop block and the arc surface of the conical frame.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] 1. In this utility model, by setting up a disassembly device, the shell and the toner cartridge body can be quickly and stably installed and disassembled by cooperating with the fixing ring, push rod, first spring, conical frame, connecting pipe, slide rod, second spring, stop block, double cone block, sliding frame and lead screw. This avoids the problem that due to the snap-on fixing structure, the snap-on strength may be too large, requiring a lot of force to open or fasten it, which is more laborious and time-consuming to operate, resulting in damage to the shell. This improves the convenience of installing and disassembling the toner cartridge body and the shell. Attached Figure Description

[0029] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0031] like Figures 1-5 As shown, this utility model provides a printer toner cartridge that can be quickly disassembled, including a toner cartridge body 1, a housing 2 mounted on the surface of the toner cartridge body 1, and a disassembly device 3 provided on the surface of the housing 2.

[0032] The specific setup and function of its disassembly device 3 will be explained below.

[0033] like Figures 2-5As shown, the disassembly device 3 includes a fixing ring 301, which is fixedly connected to the housing 2. A push rod 302 is slidably connected to the surface of the fixing ring 301. A first spring 303 is sleeved on the arc surface of the push rod 302. The two ends of the first spring 303 are fixedly connected to the fixing ring 301 and the push rod 302, respectively. A conical frame 304 is fixedly connected to one end of the push rod 302. A connecting tube 305 is slidably connected to the surface of the conical frame 304. The connecting tube 305 is fixedly connected to the drum body 1. Two sliding rods 306 are slidably connected to the arc surface of the connecting tube 305. A second spring 307 is sleeved on the arc surface of each sliding rod 306. The two ends of the second spring 307 are fixedly connected to the connecting tube 305 and the sliding rod 306, respectively. One end of the sliding rod 306 is fixed... A stop block 308 is connected, which engages with the tapered frame 304. A double cone block 309 is slidably connected to the arc surface of the push rod 302. A sliding frame 310 is fixedly connected to the surface of the double cone block 309, and the dimensions of the double cone block 309 are compatible with those of the tapered frame 304. The sliding frame 310 is slidably connected to the fixing ring 301. A lead screw 311 is threadedly connected to the surface of the sliding frame 310, and the lead screw 311 is threadedly connected to the fixing ring 301. An anti-slip pad 312 is fixedly connected to the surface of the sliding frame 310, and the anti-slip pad 312 is slidably connected to the lead screw 311. The lead screw 311 moves along the anti-slip pad 312 on the sliding frame 310. At this time, the anti-slip pad 312 increases the friction between the contact surfaces of the lead screw 311 and the sliding frame 310. One end of the screw rod 311 is fixedly connected to an elastic rope 313, and the other end of the elastic rope 313 is fixedly connected to a fixed ring 301. The screw rod 311 will drive one end of the elastic rope 313 to move. At this time, the elastic rope 313 can prevent the screw rod 311 from being lost when it loses contact with the sliding frame 310. One end of the screw rod 311 is fixedly connected to a pointed cone 314, which is a stainless steel cone. The screw rod 311 will drive the pointed cone 314 to move closer to the fixed ring 301. At this time, the pointed cone 314 can facilitate the screw rod 311 to enter the fixed ring 301. One end of the push rod 302 is fixedly connected to a push pad 315, which is a rubber pad. Pressing the push pad 315 on the push rod 302 towards the fixed ring 301 will cause the rubber material to be pressed. The push pad 315 protects the contact surface between the operator's fingers and the push rod 302. A protective pad 316, which is made of sponge, is fixedly connected to the surface of the stop block 308. The straight surface of the stop block 308 will cause the protective pad 316 to contact the conical frame 304. At this time, the sponge protective pad 316 can protect the contact surface between the straight surface of the stop block 308 and the conical frame 304. Several balls 317 are rotatably connected to the inclined surface of the stop block 308. The balls 317 are evenly distributed on the surface of the stop block 308. The arc surface of the conical frame 304 will cause the balls 317 on the inclined surface of the stop block 308 to roll. At this time, the balls 317 can reduce the friction between the inclined surface of the stop block 308 and the arc surface of the conical frame 304.

[0034] The overall working principle is as follows: When it is necessary to install the housing 2 and the toner cartridge body 1, the fixing ring 301 on the housing 2 can be aligned with the connecting tube 305 on the toner cartridge body 1. Then, the push pad 315 on the push rod 302 is pressed towards the fixing ring 301. At this time, the rubber push pad 315 can protect the contact surface between the operator's fingers and the push rod 302. Then, the push rod 302 will squeeze one end of the first spring 303. At this time, the first spring 303 will generate an outward elastic force. Then, the push rod 302 will slide along the surface of the fixing ring 301. Then, the push rod 302 will drive the conical frame 304 to move. Then, the arc surface of the conical frame 304 will move along the inclined surface of the stop block 308. The arc surface of the conical frame 304 causes the ball bearing 317 on the inclined surface of the stop block 308 to roll. At this time, the ball bearing 317 reduces the friction between the inclined surface of the stop block 308 and the arc surface of the conical frame 304. Then, the conical frame 304 pushes the two stop blocks 308 away from each other. Simultaneously, the stop blocks 308 move the slider 306, which in turn moves one end of the second spring 307. The second spring 307 then generates a retracting force. When the conical frame 304 passes through the two stop blocks 308, the second spring 307 uses its own force to move the two stop blocks 308 closer together. Simultaneously, the first spring 303 uses its elasticity to move the push rod 302 towards the conical frame. When frame 304 is reset, the conical frame 304 and the straight surface of stop 308 will abut against each other. Simultaneously, the straight surface of stop 308 will cause the protective pad 316 to contact the conical frame 304. The sponge-material protective pad 316 protects the contact surface between the straight surface of stop 308 and the conical frame 304. Then, the lead screw 311 can be rotated. The lead screw 311 will move along the surface of the sliding frame 310 using its own thread. Simultaneously, the lead screw 311 will drive the pointed cone 314 towards the fixing ring 301. The pointed cone 314 facilitates the lead screw 311 entering the fixing ring 301. Then, the lead screw 311 will move along the anti-slip pad 312 on the sliding frame 310. The anti-slip pad 312 increases the slip ratio of the lead screw. The friction between the contact surfaces of rod 311 and sliding frame 310 is utilized. When disassembly of housing 2 is required, the lead screw 311 is rotated in the reverse direction, causing one end of elastic rope 313 to move. The elastic rope 313 prevents the lead screw 311 from losing contact with the sliding frame 310. The sliding frame 310 is then pushed towards the fixing ring 301, causing it to move along the surface of the fixing ring 301, moving the double cone block 309. The double cone block 309 slides along the arc surface of push rod 302 and presses the stop block 308 into the conical frame 304. The push rod 302 is then pulled away from the fixing ring 301, causing the conical frame 304 to move.At this time, the conical frame 304 will drive the double conical block 309 to move. The arc-shaped surface of the double conical block 309 will then move the two stops 308 away from each other. The conical frame 304 can then be pulled out from between the two stops 308. By using the disassembly device 3, and through the cooperation of the fixing ring 301, push rod 302, first spring 303, conical frame 304, connecting pipe 305, slide rod 306, second spring 307, stops 308, double conical block 309, sliding frame 310, and lead screw 311, the housing 2 and the toner cartridge body 1 can be quickly and stably installed and disassembled. This avoids the problem of the snap-fit ​​structure, which may require considerable force to open or close, making operation laborious and time-consuming, and potentially damaging the housing 2. This improves the convenience of installing and disassembling the toner cartridge body 1 and the housing 2.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
