Abstract

To address the problem of existing bearing components on developer cartridges being easily interfered with during printer docking and installation, resulting in inconvenient operation, the present invention discloses a bearing component comprising a body having an end face parallel to the X1 direction; and a guide structure having a guide surface disposed on the body, the guide surface being inclined relative to the end face, the guide surface being used to guide a connecting guide. By employing this bearing component, a guide structure is disposed in the body, the guide surface being inclined relative to the end face of the body. The connecting guide first contacts the guide surface on the guide structure, which guides and gives way to the connecting guide. This effectively prevents the front section of the connecting guide from colliding with the body, correctly guiding the connecting guide along the guide structure, and making the developer cartridge installation process simple and convenient, eliminating the need for pre-visual alignment and repeated insertion.

Description

Technical Field

[0001] The present invention relates to the technical field of printing equipment, and in particular to a bearing component, a developing box and a printer. Background Art

[0002] A developer cartridge is a consumable component widely used in imaging devices such as laser printers / copiers. When the developer in the developer cartridge is used up, the imaging device will remind the user to replace it with a new one.

[0003] The connecting guide in the printing device contacts the coupling part through the groove in the bearing component, thereby restricting the coupling part. During actual operation, the connecting guide and the groove can easily interfere with each other, resulting in the developer box being unable to fall into the machine normally. It is often necessary to take out the developer box and re-align it before assembly. However, the matching position of the connecting guide and the groove cannot be observed and can only be aligned visually in advance, which is very inconvenient during use and installation. Summary of the Invention

[0004] The present invention provides a bearing component, aiming to solve at least one of the technical problems existing in the prior art.

[0005] A first aspect of the technical solution of the present invention relates to a bearing member for a developer cartridge, wherein the developer cartridge is disposed in a printer, the printer being provided with a connecting guide, and the direction in which the developer cartridge is installed in the printer being set as an X1 direction, characterized in that the bearing member further comprises:

[0006] A body having an end surface, wherein the end surface is parallel to the X1 direction;

[0007] A guide structure is provided with a guide surface, the guide structure is provided on the body, and the guide surface is inclined to the end surface, and the guide surface is used to guide the connecting guide

[0008] Furthermore, the guide structure is configured as a groove, which is provided on the end face. The groove is composed of a guide surface, a first surface and a second surface. The first surface and the second surface are both perpendicular to the guide surface. The first surface and the second surface are parallel to each other and perpendicular to the end face. The guide surface is arranged inclined to the end face, and the guide surface is used to guide the connecting guide.

[0009] Furthermore, the end of the guide surface close to the middle of the body is the first end, and the end away from the middle of the body is the second end. The guide surface gradually moves away from the end surface from the first end toward the second end, and the moving away direction is toward the other side of the body.

[0010] Furthermore, the first surface is connected to an inclined surface, the inclined surface is inclined in a direction away from the second surface, and the inclined surface is used to guide the guide connection member to move along the groove.

[0011] Furthermore, the guiding structure is configured as a spring sheet, the guiding surface is provided above the spring sheet, and one end of the spring sheet is movably connected to the main body.

[0012] Furthermore, the spring piece and the body are integrally formed.

[0013] Furthermore, the guiding structure is configured as a spring, a side end of the spring is hinged to the body, and a torsion spring is provided at the hinge between the spring and the body.

[0014] Furthermore, a guiding arc surface is provided at the other end of the elastic piece.

[0015] A second aspect of the technical solution of the present invention relates to a developing box, comprising the bearing component of the first aspect.

[0016] A third aspect of the technical solution of the present invention relates to a printer, comprising the developing cartridge of the second aspect.

[0017] The beneficial effects of the present invention are as follows.

[0018] 1. By providing a guide structure in the main body, and providing a guide surface inclined to the end surface of the main body on the guide structure, when the developer cartridge provided with the bearing component of the guide structure is installed into the printer, the connecting guide in the printer first contacts the guide surface on the guide structure. At this time, the inclined guide surface guides and gives way to the connecting guide, which can effectively avoid the problem of collision and interference between the front section of the connecting guide and the main body. The connecting guide can be correctly guided to enter along the guide structure and contact with the coupling, making the installation process of the developer cartridge simple and convenient, and no longer requiring advance visual alignment and repeated insertion processes.

[0035] Reference Figures 1 to 3 as well as Figure 5 According to the first aspect of the present invention, a bearing component is used for a developer cartridge, which is arranged in a printer, and the bearing component is assembled on the developer cartridge, and the bearing component is provided with a mounting hole 140, and a coupling member is passed through the mounting hole 140, which is used to be connected to a connecting guide on the printer, and then the driving device on the printer drives the coupling member through the connecting guide to drive the photosensitive drum to rotate, and the direction in which the developer cartridge is installed into the printer is set to be the X1 direction, and the bearing component includes a body, and the body 100 is provided with an end face 110, and the end face 110 is parallel to the X1 direction, and a guide structure is provided on the body, and a guide surface 230 is provided on the guide structure, and the guide surface 230 is arranged obliquely to the end face 110, and the guide surface 230 is used to guide the connecting guide.

[0036] The application of the bearing component of the above embodiment has the following beneficial effects: by providing a guide structure in the main body, and providing a guide surface 230 inclined to the end face 110 of the main body 100 on the guide structure, when the developing box with the bearing component provided with the guide structure is installed in the printer, the connecting guide in the printer first contacts the guide surface 230 on the guide structure. At this time, the inclined guide surface 230 plays a guiding and giving way role for the connecting guide, which can effectively avoid the problem of collision and interference between the front section of the connecting guide and the main body 100, and can correctly guide the connecting guide to enter along the guide structure and contact with the coupling part, so that the installation process of the developing box is simple and convenient, and there is no need to perform advance visual alignment and repeated insertion processes.

[0037] According to some embodiments of the present invention, referring to Figures 1 to 3 A groove 200 is provided on the end face 110 of the main body 100. The groove 200 is composed of a guide surface 230, a first surface 210 and a second surface 220. The first surface 210 and the second surface 220 are both perpendicular to the guide surface 230. The first surface 210 and the second surface 220 are parallel to each other and perpendicular to the end face 110. The guide surface 230 is arranged obliquely to the end face 110. The guide surface 230 is used to guide the connecting guide.

[0038] The bearing component adopts the above-mentioned structure, and the first surface 210, the second surface 220 and the guide surface jointly form a groove 200 on the end surface 110 of the main body 100, and the guide surface 230 is inclined to the end surface 110. When the developer box equipped with the bearing component is installed in the printer, the connecting guide in the printer first contacts the groove 200. At this time, the inclined guide surface 230 plays a guiding and giving way role for the connecting guide, which can effectively avoid the problem of collision and interference between the front section of the connecting guide structure and the end of the groove 200, and can correctly guide the connecting guide structure to enter along the groove 200 and contact with the coupling part, so that the installation process of the developer box is simple and convenient, and there is no need to perform advance visual alignment and repeated insertion processes.

[0039] According to some embodiments of the present invention, referring to Figures 1 to 3 The end of the guide surface 230 close to the middle of the main body 100 is the first end 231, and the end away from the middle of the main body 100 is the second end 232. The guide surface 230 gradually moves away from the end surface 110 from the first end 231 toward the second end 232, and the moving away direction is toward the other side of the main body 100. It can be understood that the guide surface 230 is not parallel to the end surface 110, and the two form a certain angle. The above-mentioned moving away direction can be understood as: the end surface 110 of the main body 100 is the front side, and the opposite side is the back side, and the extension direction of the second end 232 is toward the back side.

[0040] In the above embodiment, referring to Figure 3 , the first end 231 is located below the end surface 110, and the second end 232 is further away from the end surface 110 than the first end 231, that is, Figure 3 The guide surface 230 shown in FIG. 2 is inclined downward from left to right from the first end 231 to the second end 232 .

[0041] In addition to the above embodiments, the first end 231 can also be set at the end surface 110, that is, the first end 231 of the guide surface 230 is directly connected to the end surface 110, and the second end 232 is located below the end surface 110 to form an inclined groove 200. The above embodiments are for illustration only and are not limited to the above implementation methods.

[0042] According to some embodiments of the present invention, referring to Figure 1 The first surface 210 is connected to an inclined surface 211, which is inclined in a direction away from the second surface 220. The inclined surface 211 is used to guide the connecting member to move along the groove 200. During use and installation, the guide surface 230 can guide the connecting guide member longitudinally perpendicular to the X1 direction, and the inclined surface 211 can further guide the connecting guide member laterally perpendicular to the X1 direction, so that the connecting guide member can be fully guided, further avoiding interference and further guiding, making the installation process easier and more convenient.

[0043] According to some embodiments of the present invention, referring to Figures 1 to 3 , and also includes a third surface 120, the third surface 120 is perpendicular to the first surface 210 and the second surface 220, one end of the third surface 120 is connected to the end surface 110 and the third surface 120 is arranged obliquely to the end surface 110, and the second end 232 is farther away from the end surface 110 than the other end of the third surface 120. The third surface 120 can reduce the volume of the main body 100, and can also play a guiding role in the installation process.

[0044] According to some embodiments of the present invention, referring to Figures 1 to 3 , and also includes a fourth surface 130, the two ends of the fourth surface 130 are respectively connected to the other end of the third surface 120 and the second end 232, the inclined surface 211 degrees of the fourth surface 130 relative to the end surface 110 is greater than the inclined surface 211 degrees of the third surface 120 relative to the end surface 110, and the fourth surface 130 is set to an arc-shaped section. The fourth surface 130 can reduce the volume of the main body 100 and can play a leading guiding role. In addition, the setting of the third surface 120 and the fourth surface 130 can reduce the sharp angle part of the main body 100, and can make the edge part of the main body 100 more structurally strong. Since this part is used for docking and installation with the printer, it is prone to collision, which can effectively reduce the cracking and damage caused by collision.

[0045] According to some embodiments of the present invention, referring to Figure 5 The guiding structure is set as a spring clip 300, one end of the spring clip 300 is movably connected to the body 100, and the other end of the spring clip 300 can move. The upper end surface of the spring clip 300 is set as a guide surface 230. The connecting guide first contacts the guide surface 230 of the spring clip 300 and presses the other end of the spring clip 300 downward. The other end of the spring clip 300 generates elastic potential energy of rebound and forms a reverse force on the connecting guide. In the process, it plays a dynamic guiding role on the connecting guide to ensure that the connecting guide enters the correct coupling position.

[0046] In the above example, the spring 300 and the body 100 are integrally formed parts, both of which are elastic plastic parts. The integrally formed injection molding structure is easy to process and can be replaced as a whole during maintenance. Assembly and subsequent repair and maintenance operations are simple and convenient.

[0047] In the above embodiment, the spring clip 300 can also be detachably connected to the main body 100. One end of the spring clip 300 is hinged to the main body 100, and the other end can rotate along the hinge. A torsion spring can be provided at the hinge so that the spring clip 300 can rebound to achieve the same effect as above.

[0048] In addition to the above embodiments, the side end of the spring clip 300 can also be hinged to the main body 100, and a torsion spring can be provided at the hinge. The torsion spring keeps the end of the spring clip 300 away from the center of the main body 100 at a low position and the end close to the center of the main body 100 at a high position. It can also serve as a guide for the connecting guide. In this embodiment and the above embodiments, the spring clip 300 always maintains a tendency to rebound, and the end of the spring clip 300 close to the center of the main body 100 always maintains a tendency to move upward. This end can press the connecting guide to make the coupling of the connecting guide more secure.

[0049] In the above embodiment, a guiding arc surface 310 is provided at the other end of the spring piece 300. It can be understood that the other end of the spring piece 300 refers to the end of the spring piece 300 close to the center of the main body 100. The guiding arc surface 310 can play a guiding role when the connecting guide is withdrawn from the coupling. At the same time, the arc surface structure can ensure that the connecting guide will not be damaged by the scratches of sharp parts when withdrawing, thereby ensuring the integrity of the connecting guide.

[0050] According to some embodiments of the present invention, referring to Figure 1 and Figure 3 A mounting hole 140 is provided in the middle of the body 100 to allow the coupling to pass through, and the groove 200 extends from the mounting hole 140 toward the outside of the body 100, that is, the groove 200 forms an avoidance passage for the entry of the connecting guide.

[0051] According to some embodiments of the present invention, referring to Figure 1 and Figure 3 A mounting shaft 150 for connecting a gear is provided on a side of the body 100 away from the end surface 110 , that is, on the reverse side of the body 100 .

[0052] According to a second aspect of the present invention, a developing cartridge, referring to Figure 4 , having the bearing component of the first aspect mentioned above.

[0053] A printer according to a third aspect of the present invention includes the developing cartridge according to the second aspect.

[0054] It should be noted that the above embodiment is mainly used for printers, but it should not be understood that it can only be used for printers. It can also be applied to various types of printing equipment, copying equipment and electronic imaging equipment.
