The shape of the box body 210 may be a hexahedron or a cylinder, and the specific shape may be designed according to actual needs. The specific position of the toner cartridge opening 220 should be arranged according to actual needs, so that toner can be conveniently filled. For example, FIG. 2 shows a cartridge 210 with a toner cartridge opening 220 that opens onto the upper end of the cartridge 210, and the toner cartridge opening 220 is a circular, open-like structure. When manufacturing the toner cartridge body 200, the toner cartridge body 200 may be directly formed in an injection molding manner.

FIG. 3 is a bottom view of the toner cartridge cover of the present embodiment. Fig. 2 and 3 show a mating structure of the toner cartridge cover 100 and the toner cartridge body 200.

As shown in fig. 2, the standing wall 230 of the toner cartridge body 200 may be a circular cylindrical structure protruding outside the cartridge body 210, and the outer surface of the standing wall 230 is provided with external threads 231. Correspondingly, as shown in fig. 3, the inner surface of the side wall 120 of the toner cartridge cover 100 is provided with an inner thread 121, and the inner thread 121 is used for being in threaded connection with the outer thread 231 on the toner cartridge body 200, so that the toner cartridge cover 100 is mounted on the toner cartridge body 200, and the connection reliability of the toner cartridge cover 100 and the toner cartridge body 200 can be ensured by using threaded connection, so that the toner cartridge cover 100 and the toner cartridge body 200 can be flexibly dismounted, and an operator can fill toner at any time without using a manual jig.

When the thread structure of the vertical wall 230 is manufactured, the external thread 231 may be directly formed on the toner cartridge body 200 by using a threading or cutting method, or the toner cartridge body 200 having the external thread 231 may be directly formed by using a plastic film method. Similarly, in making the thread structure of the sidewall 120, tapping or cutting may be used to directly form the internal thread 121 on the toner cartridge cover 100, or a plastic film may be used to directly form the toner cartridge cover 100 with the internal thread 121.

Continuing to refer to fig. 2 and 3, a mating arrangement of the toner cartridge cover 100 and the toner cartridge body 200 for anti-loosening is shown.

Illustratively, a plurality of snaps 130 may be spaced about the outer surface of the side wall 120 of the toner cartridge cover 100. the snaps 130 are generally cylindrical in configuration and are securely fastened to the side wall 120. Accordingly, a plurality of locking portions 240 are provided at intervals near the upright wall 230 of the cartridge body 200. The locking portion 240 has a substantially cylindrical structure, and defines a slot 241 for the clip 130 to pass through with the upright wall 230, and can be locked with the locking portion 240 after the clip 130 passes through the slot 241. The buckle 130 arranged on the outer surface of the side wall 120 can be matched with the locking part 240 of the toner cartridge body 200, that is, the outer surface of the toner cartridge cover 100 can be matched with the toner cartridge body 200, so that the inner surface of the toner cartridge cover 100 is matched with the thread of the toner cartridge body 200, and the connection reliability of the toner cartridge cover 100 and the toner cartridge body 200 is improved.

Optionally, each of the clips 130 disposed around the sidewall is correspondingly provided with a matching locking portion 240. So that the buckle 130 and the corresponding locking part 240 cooperate to form an anti-loose structure, and the toner cartridge cover 100 cannot rotate in the reverse direction of the screwing direction, so that the toner cartridge cover 100 and the toner cartridge body 200 are locked in a thread manner, and the effect of preventing the toner cartridge body 200 from being separated from the toner cartridge cover 100 is achieved. The plurality of matched buckles 130 and locking parts 240 are arranged on the toner cartridge cover 100 and the toner cartridge body 200, so that further loosening prevention is facilitated; and each buckle 130 all corresponds and sets up a locking portion 240, can make each buckle 130 all can be through locking portion 240 rather than corresponding with cartridge body 200 locking to further improve the locking force of carbon powder lid 100 and cartridge body 200, be favorable to preventing the two pine from taking off.

The locking portion 240 may be made of a resilient material so that when the toner cartridge cover 100 is threadably engaged with the toner cartridge body 200 and the latch 130 contacts the locking portion 240, the shape of the engaging groove 241 may be changed and the latch 130 of the toner cartridge cover 100 may be pushed through the engaging groove 241 near the toner cartridge opening 220. When the toner cartridge cover 100 is rotated clockwise to be mounted on the toner cartridge body 200, the latch 130 contacts the locking portion 240 to force the locking portion 240 to elastically deform in a direction away from the upright wall 230, so that the engaging groove 241 is widened to allow the latch 130 to smoothly pass through. After the buckle 130 passes through the clamping groove 241, the locking portion 240 restores to the original state to fix the buckle 130, thereby blocking the movement of the buckle 130 in the counterclockwise direction, preventing the disengagement of the buckle 130 from the locking portion 240, and locking the toner cartridge cover 100 and the toner cartridge body 200. Of course, in other implementations, the latch 130 may be elastically deformed, that is, the latch 130 is made of a material having elasticity.

Of course, although the screwing direction of the toner cartridge cover 100 and the toner cartridge body is described as clockwise, in other examples, the screwing direction may be counterclockwise.

When manufacturing the snap 130 of the toner cartridge cover 100, the snap 130 can be glued to the sidewall 120 or the toner cartridge cover 100 with the snap 130 can be directly formed by injection molding. Similarly, the locking portion 240 of the toner cartridge body 200 may be adhered to the toner cartridge body 200 by gluing.

It will be appreciated that the shape of the latch 130 and the shape of the latching portion 240 are designed to fit together.

For example, FIG. 3 shows a toner cartridge cover 100 with two snaps 130, where the snaps 130 are cylindrical structures with a cross-section that approximates a triangle. The clip 130 is disposed at the lower portion of the sidewall 120, and the lower end surface of the clip 130 is flush with the annular end surface of the sidewall 120, so that the clip 130 can be sufficiently contacted with the locking portion 240 after being screwed. One side of the latch 130 is fixedly connected to the sidewall 120, and the other two sides are located outside the sidewall 120 and intersect with the sidewall 120, and the two sides may be a combination of an arc and a rectangular plane, wherein the rectangular plane is perpendicular to the sidewall 120 and is used for matching with the side of the locking portion 240. Correspondingly, as shown in fig. 2, two locking portions 240 are disposed on the toner cartridge body 200, the locking portions 240 may be designed to be rectangular columnar structures, and a cylindrical surface corresponding to the buckle 130 is used for matching with a rectangular side surface of the buckle 130, so as to abut against the buckle 130, and the locking portions 240 are clamped and fixed with the buckle 130.

When the toner cartridge body 200 is in threaded connection with the toner cartridge cover 100, the buckle 130 rotates along with the toner cartridge cover 100, the arc surface of the buckle 130 is extruded into the clamping groove 241 from the near end to the far end, and after the buckle 130 passes through the clamping groove 241, the rectangular side surface of the buckle 130 is abutted to the locking part 240. After the toner cartridge body 200 and the toner cartridge cover 100 are in threaded connection, the buckle 130 is tightly engaged with the locking part 240 under the action of thread shearing stress, so that the toner cartridge cover 100 is prevented from being reversed and loosened from the toner cartridge body 200, that is, the matching structure of the buckle 130 and the locking part 240 is clamped, and when the matching threaded connection is used, the effect of preventing the reversing or the loosening can be achieved.

In some examples, the latch 130 and the detent 240 may also be configured to prevent disengagement using a snap fit connection. For example, the snap 130 may be provided as a cylindrical structure with snap protrusions that are located on the cylindrical surface of the toner cartridge cover 100 in the screwing direction. Correspondingly, the locking portion 240 may be provided with a groove matching the protrusion of the engaging protrusion, and the groove is disposed on the cylindrical surface corresponding to the protrusion of the engaging protrusion 130, so as to engage and fix with the engaging protrusion 130, thereby preventing the toner cartridge cover 100 from rotating in the reverse direction of the screwing direction, and further preventing the toner cartridge cover 100 from loosening from the toner cartridge body 200.

In other examples, the clip 130 may also be disposed on the upper end of the outer surface of the sidewall 120. For example, when the standing wall 230 of the toner cartridge body 200 is disposed inside the toner cartridge body 200, and the inner surface of the standing wall 230 is provided with the internal thread 121. Correspondingly, the outer surface of the side wall 120 of the toner cartridge cover 100 is provided with external threads 231 for threaded engagement with the internal threads 121 on the inner surface of the upright wall 230. After the toner cartridge cover 100 is screwed to the toner cartridge body 200, the sidewall 120 is disposed inside the toner cartridge body 200, and therefore, the latch 130 is disposed on the upper end of the outer surface of the sidewall 120 to engage with the locking portion 240 of the toner cartridge body 200.

FIG. 4 is a schematic structural view of a sealing ring provided in the toner cartridge cover 100 for preventing toner leakage. As shown in fig. 4, the seal 140 is an annular elastic body, the upper end surface of the annular structure of the seal 140 abuts against the inner surface of the cover 110, the lower end surface of the annular structure of the seal 140 abuts against the annular opening of the upright wall 230, and the annular structure of the seal 140 seals the gap between the cover 110 and the upright wall 230, thereby preventing toner from leaking from the gap between the toner cartridge body 200 and the toner cartridge cover 100. Of course, in other examples, a sealing sheet or a labyrinth seal structure may be provided to achieve sealing. It will be appreciated that the provision of the annular sealing ring 140 reduces the amount of sealing material used, thereby reducing the cost of manufacture and use of the toner cartridge.

As shown in FIG. 3, an attachment groove 122 may be provided on the inner surface of the cover body 110 of the toner cartridge cover 100 to facilitate the attachment of a sealing ring 140, thereby reducing assembly time, improving assembly efficiency, and further reducing the possibility of toner leakage.

It should be understood that the shape of the mounting groove 122 should be designed according to the shape of the sealing ring 140 so that the sealing ring 140 is placed in the mounting groove 122 without being loosened.

The sealing ring 140 may be made of a rubber material, so that the sealing ring 140 has good elasticity while having certain corrosion resistance, thereby obtaining better sealing performance.

The sealing ring 140 is installed inside the toner cartridge cover 100 through the installation groove 122, after the toner cartridge cover 100 is screwed with the toner cartridge body 200, the sealing ring 140 inside the toner cartridge cover 100 contacts with the annular opening end face of the toner cartridge body 200, and the sealing ring 140 is slightly deformed under the tensile stress of the screw thread, so that the contact gap between the sealing cover body 110 and the upright wall 230 is sealed, and the leakage of the toner in the toner cartridge body 200 is prevented.

In one example, the mounting groove 122 may be omitted from the inside surface of the toner cartridge cover 100, with the seal 140 being non-removably secured directly to the toner cartridge cover 100. For example, the sealing ring 140 may be adhered to the inner surface of the cover 110 by using a special glue. In other examples, the cover 110 may be integrated with the sealing ring 140. For example, the cover 110 with an annular pillar structure on the inner surface is directly made of rubber material to seal the toner cartridge opening 220 of the toner cartridge body 200.

Fig. 5 is a schematic structural diagram of a toner cartridge according to an embodiment of the present invention.
