A processing box and an image forming apparatus

Abstract

This application relates to the field of image printing technology, and more particularly to a processing box and an image forming apparatus. The processing box is detachably installed in the image forming apparatus, which includes a body. The processing box includes: a box body; an end cover mounted on one side of the box body, with a first groove on the side of the end cover away from the box body for a first limiting part of the body to pass through. During the installation of the processing box, the first groove cooperates with the first limiting part of the body, allowing the first limiting part to at least partially pass through the first groove. If the processing box is incorrectly positioned or if there is a deviation in posture during installation, the processing box will interfere with the first limiting part, prompting the user to adjust the installation. If the processing box is correctly positioned, the first limiting part can insert into the first groove and move along the first groove, limiting the installation position of the processing box through the cooperation between the first limiting part and the first groove, preventing the processing box from shifting or tilting, and ensuring the accuracy of the processing box installation.

[0009] The first groove is located on the side of the end cap away from the handle, and the first groove can extend to the edge of the end cap.

[0010] In one possible design, the end cap has a guide portion on the side away from the box body, the guide portion being located on the side of the end cap near the handle, and the guide portion being used to slide in conjunction with the guide groove of the body.

[0011] In one possible design, along the direction of installation of the processing box, the end cap further includes a bottom side and a rear side, the bottom side and the rear side being located on the side of the end cap away from the handle, and the rear side and the bottom side being arranged sequentially along the direction of installation of the processing box;

[0012] The first groove has a sidewall, and one end of the sidewall is connected to the rear sidewall along the installation direction of the processing box.

[0013] In one possible design, the first groove includes a first portion and a second portion;

[0014] The cross-section of the first part gradually increases in the direction close to the second part, and the cross-section of the second part gradually decreases in the direction away from the first part;

[0015] When the processing box is installed, the direction of movement of the processing box relative to the first limiting part is from the first part to the second part.

[0016] In one possible design, the processing box includes fasteners that connect the end cap to the box body;

[0017] The fastener is located in the first groove.

[0018] In one possible design, the box body is provided with a second limiting part;

[0019] During the installation of the processing box, the second limiting part is used to cooperate with the second groove of the body, so that the second limiting part can pass through the second groove.

[0020] In one possible design, the second limiting portion is located at the end of the box body away from the first groove.

[0021] In one possible design, the processing box further includes a handle connected to the box body;

[0022] The second limiting part is located on the side of the box body away from the handle.

[0023] In one possible design, the second limiting part includes a first part and at least two second parts, the at least two second parts being spaced apart, and the second parts being intersected with the first part.

[0024] This application also provides an image forming apparatus, the image forming apparatus comprising:

[0025] The body has a mounting cavity for mounting the processing box, and the body has a first limiting part located inside the mounting cavity;

[0026] The first limiting part is used to cooperate with the first groove on the processing box;

[0027] During the process of inserting the processing box into the mounting cavity, the first limiting part cooperates with the first groove, so that the first limiting part at least partially passes through the first groove.

[0035] The technical solution provided in this application can achieve the following technical effects:

[0036] When the processing box is correctly positioned and there is no offset or tilting during installation, the first limiting part can be inserted into the first groove and move along the first groove. The cooperation between the first limiting part and the first groove restricts the installation position of the processing box, preventing the processing box from offsetting or tilting and ensuring the accuracy of the processing box installation. If the processing box is incorrectly positioned or there is a posture shift during installation, the processing box will interfere with the first limiting part, reminding the user to adjust the installation of the processing box.

[0037] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

[0080] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0081] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0082] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0083] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0084] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0085] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0086] like Figure 1 , Figure 2 and Figure 12 As shown, this embodiment provides an image forming apparatus 1, which includes a body 11 and a processing box 12. The body 11 has a mounting cavity 111, and the processing box 12 is detachably mounted in the mounting cavity 111 of the body 11.

[0087] Among them, such as Figure 12 As shown, the body 11 includes a first side plate 112 and a second side plate 113 disposed opposite to each other. The first side plate 112 and the second side plate 113 can form a mounting cavity 111. The body 11 also includes a protective plate 114 for forming the mounting cavity 111, and the protective plate 114 is located between the first side plate 112 and the second side plate 113. Figure 7 As shown, the processing box 12 includes a box body 121 and an end cap 122, with the end cap 122 mounted on one side of the box body 121.

[0088] The end cap 122 and the box body 121 are designed separately, and the end cap 122 and the box body 121 are either detachably connected or fixedly connected.

[0089] Alternatively, the end cap 122 and the box body 121 may be integrally formed.

[0090] Although the first side plate 112 and the second side plate 113 can provide some restraint when the processing box 12 is installed into the mounting cavity 111, the distance between the first side plate 112 and the second side plate 113 is greater than the length of the processing box 12, and the processing box 12 may shift or tilt during installation. Therefore, as follows: Figures 2 to 4As shown, in this embodiment, the protective plate 114 is provided with a first limiting part 114a, which is located at the end of the protective plate 114 near the first side plate 112. The end cap 122 is provided with a first groove 122a on the side away from the box body 121. During the process of installing the machine body 11 on the processing box 12, the first limiting part 114a can be inserted into the first groove 122a and move along the first groove 122a, so that at least a portion of the first limiting part 114a passes through the first groove 122a.

[0091] like Figure 4 As shown, in this embodiment, a first limiting part 114a is provided on the protective plate 114, and a first groove 122a is provided on the end cover 122. Through the cooperation of the first limiting part 114a and the first groove 122a, when the processing box 12 is installed on the body 11, the processing box 12 is limited between the first limiting part 114a and the second side plate 113. If the processing box 12 is not installed in the correct position or if there is a posture deviation during the installation process, the processing box 12 will interfere with the first limiting part 114a, reminding the user to adjust the installation of the processing box 12. If the processing box 12 is installed in the correct position and there is no deviation or tilting during the installation process, the first limiting part 114a can be inserted into the first groove 122a and move along the first groove 122a until at least part of the first limiting part 114a passes through the first groove 122a. Therefore, by limiting the installation position of the processing box 12 through the cooperation of the first limiting part 114a and the first groove 122a, the processing box 12 can be prevented from shifting or tilting, ensuring the accuracy of the installation of the processing box 12. At the same time, if the first groove 122a is not provided, the first limiting part 114a needs to be set in the gap between the end cover 122 and the body. If the gap is small, the thickness of the first limiting part 114a will be very thin and the strength will be low. It will be easily damaged in the event of a collision or other situations. After being damaged, it will no longer be able to perform the guiding and limiting function for the installation of the processing box 12. If the gap is large, the size of the space in the body used to accommodate the processing box 12 will be large. However, by providing the first groove 122a on the end cover 122, the gap between the end cover 122 and the body can be set to be smaller, reducing the size of the body and facilitating the miniaturization of the image forming apparatus. At the same time, the thickness of the first limiting part 114a will not be too thin, making it less prone to damage.

[0092] Furthermore, the cooperation between the first limiting part 114a and the first groove 122a can restrict the installation of the processing box 12. If the processing box 12 is installed incorrectly, the first limiting part 114a will not pass through the first groove 122a, which will cause the first limiting part 114a to interfere with other parts on the processing box 12, making it impossible for the processing box 12 to be installed into the body 11. Therefore, the cooperation between the first limiting part 114a and the first groove 122a can also prevent installation errors.

[0093] like Figure 7As shown, in some embodiments, the processing box 12 further includes a handle 123, which is connected to the box body 121. The user can pick up the processing box 12 through the handle 123, making it easy to push the handle 123 to install the processing box 12 into the machine body 11. That is, the handle 123 is located near the cover of the machine body 11 relative to the box body 121. In this embodiment, the first groove 122a is located on the side of the end cover 122 away from the handle 123, so that when the processing box 12 is installed into the mounting cavity 111 of the machine body 11, the first limiting part 114a can be inserted into the first groove 122a more quickly. Through the sliding cooperation between the first limiting part 114a and the first groove 122a, the processing box 12 is restricted from shifting or tilting during the installation process.

[0094] And, as Figure 8 and Figure 9 As shown, the first groove 122a can extend to the edge of the end cap 122, that is, the side of the first groove 122a near the edge of the end cap 122 is not provided with a side wall 122a1, which ensures the stability of the first limiting part 114a and the first groove 122a. While the first limiting part 114a and the first groove 122a cooperate to play a limiting role, the processing technology of the first limiting part 114a and the first groove 122a is simplified.

[0095] like Figure 9 As shown, in some embodiments, the first groove 122a includes a first portion 122a2 and a second portion 122a3. The cross-section of the first portion 122a2 gradually increases in the direction approaching the second portion 122a3, and the cross-section of the second portion 122a3 gradually decreases in the direction away from the first portion 122a2. When the processing box 12 is installed into the mounting cavity 111 of the body 11, the movement direction of the processing box 12 relative to the first limiting portion 114a is from the first portion 122a2 to the second portion 122a3. In this embodiment, the first limiting part 114a does not pass through the first part 122a2 within the first groove 122a. The first limiting part 114a enters the first groove 122a along the end of the second part 122a3 with a larger space, which facilitates the entry of the first limiting part 114a into the first groove 122a. Then, it moves along the direction from the first part 122a2 to the second part 122a3. As the space of the second part 122a3 gradually decreases, it restricts the first limiting part 114a from shifting when it moves along the second part 122a3, thereby restricting the offset of the installation position of the processing box 12.

[0096] It should be noted that the movement of the processing box 12 relative to the first limiting part 114a is not entirely along a fixed direction, but rather, at a certain stage of the movement, the direction is from the first part 122a2 to the second part 122a3. Of course, in other embodiments, the movement of the processing box 12 relative to the first limiting part 114a may also be along a fixed direction, that is, the entire movement is along the first part DD230405I.

[0097] Move in the direction from part 122a2 to the second part 122a3.

[0098] like Figure 9 As shown, the end cap 122 further includes a bottom side surface 122d and a rear side surface 122b. The bottom side surface 122d and the rear side surface 122b are located on the side of the end cap 122 away from the handle 123. The rear side surface 122b and the bottom side surface 122d are arranged sequentially along the installation direction of the processing box 12. The rear side surface 122b is an arc surface. The first groove 122a is provided with a side wall 122a1. The side wall 122a1 is a curved surface. The distance between the side wall 122a1 and the edge position of the adjacent end cap 122 gradually increases, then gradually decreases, and finally gradually increases again along the installation direction of the processing box 12. The bottom side surface 122d is a plane or approximately a plane, and the rear side surface 122b is the surface that contacts the bottom side surface 122d. Along the installation direction of the processing box 12, one end of the side wall 122a1 is connected to the rear side surface 122b. In this embodiment, by extending the sidewall 122a1 of the second part 122a3 to connect with the rear side surface 122b of the end cover 122, even if the user applies too much force when the processing box 12 is installed, the first limiting part 114a will not collide with the first groove 122a and cause damage to the processing box 12 even if the first limiting part 114a moves along the first groove 122a to the rear side surface 122b of the end cover 122.

[0099] Optionally, the end cap 122 also includes a front and a back side, the back side being the side of the end cap 122 close to the box body 121, and the front side being the side of the end cap 122 away from the box body 121. The first groove 122a is recessed from the front side of the end cap 122 toward the back side.

[0100] like Figure 4 and Figure 9 As shown, when the first limiting part 114a is at least partially located in the first groove 122a, there is a gap between the first limiting part 114a and the side wall 122a1, which can prevent the first limiting part 114a from scratching or colliding with the side wall 122a1, reduce damage to the first limiting part 114a, and make the installation of the processing box 12 smoother.

[0101] Similarly, when the first limiting part 114a is located in the first groove 122a, the first limiting part 114a and each groove wall in the first groove 122a are in clearance fit.

[0102] In other embodiments, the first limiting part 114a may also be a guide wheel rotatably disposed on the body. The guide wheel may also play a limiting and guiding role during the installation of the processing box 12. When the guide wheel is at least partially located in the first groove 122a, the guide wheel may contact the side wall 122a1. The guide wheel may rotate during the installation of the processing box 12, which can reduce the wear on the guide wheel and the processing box 12 and make the installation of the processing box 12 smoother.

[0103] like Figure 8 As shown, a guide portion 122c is provided on the side of the end cap 122 away from the main body 121. The guide portion 122c is located on the side of the end cap 122 near the handle 123 and is used to slide with the guide groove (not shown in the figure) of the machine body. The cooperation between the guide portion 122c and the guide groove guides the installation of the processing box 12, ensuring the accuracy of the installation of the processing box 12. When the guide portion 122c cooperates with the guide groove, it can initially limit the position of the processing box 12 in the machine body, which is beneficial to the subsequent alignment of the first limiting part 114a and the first groove 122a, and can reduce the occurrence of installation misalignment or inaccurate alignment.

[0104] The guide portion 122c and the first groove 122a are located at both ends of the end cap 122.

[0105] like Figure 4 and 9 As shown, in some embodiments, the processing box 12 includes a fastener 124 that connects the end cap 122 and the box body 121. The fastener 124 is located in a first groove 122a. In this embodiment, the fastener 124 is disposed within the first groove 122a, specifically in the first portion 122a2 of the first groove 122a. A portion of the fastener 124 passes through the end cap 122 and connects to the box body 121 to fix the end cap 122 and the box body 121. The fastener 124 can be a bolt, screw, etc. By setting the first groove 122a at the location where the fastener 124 is located, the first groove 122a can be machined simultaneously with the location of the fastener 124, simplifying the manufacturing process.

[0106] like Figure 13As shown, in some embodiments, the protective plate 114 is further provided with a reinforcing portion 114b, which is disposed close to the first limiting portion 114a. The reinforcing portion 114b can support the first limiting portion 114a and prevent the first limiting portion 114a from being damaged by the powder box after collision, thus affecting the limiting effect of the first limiting portion 114a. The first limiting portion 114a and the reinforcing portion 114b can be an integral structure, formed integrally on the protective plate 114 during manufacturing. The first limiting portion 114a is a protrusion protruding away from the protective plate 114, and the reinforcing portion 114b is a protrusion connected to the first limiting portion 114a.

[0107] like Figure 5 and Figure 6 As shown, in some embodiments, the box body 121 is provided with a second limiting part 121a, and the machine body 11 is provided with a second groove 115. During the process of installing the processing box 12 into the mounting cavity 111 of the machine body 11, the second limiting part 121a can be inserted into the second groove 115 and move along the second groove 115, allowing the second limiting part 121a to pass through the second groove 115. When the second limiting part 121a moves along the second groove 115, the second groove 115 can limit the second limiting part 121a, thereby restricting the processing box 12 from shifting or tilting during installation. Based on the cooperation between the first limiting part 114a and the first groove 122a, the cooperation between the second limiting part 121a and the second groove 115 further ensures the accuracy of the installation of the processing box 12. The second limiting part 121a is a protruding block that protrudes away from the box body 121.

[0108] like Figure 7 , Figure 8 and Figure 12 As shown, the second limiting part 121a is located on the side of the box body 121 away from the first groove 122a. Correspondingly, the second groove 115 is provided at one end of the guard plate 114 near the second side plate 113, so that the first limiting part 114a and the second limiting part 121a respectively limit the two ends of the processing box 12. Under the cooperative action of the two, the limiting effect on the processing box 12 is improved.

[0109] The second limiting part 121a is located on the side of the box body 121 away from the handle 123. By setting the second limiting part 121a on the side of the box body 121 away from the handle 123, when the processing box 12 is installed into the mounting cavity 111 of the machine body 11, the second limiting part 121a can be inserted into the second groove 115 more quickly. Through the sliding cooperation between the second limiting part 121a and the second groove 115, the processing box 12 is restricted from shifting and tilting during the installation process.

[0110] like Figure 10 and Figure 11As shown, the second limiting portion 121a includes a first segment 121a1 and at least two second segments 121a2, which are spaced apart and intersected with the first segment 121a1. When there is one first segment 121a1 and two second segments 121a2, the second limiting portion 121a is inverted "I" shape. The second segments 121a2 can be sheet-like or plate-like structures, and are arranged parallel or approximately parallel to each other. The number of first segments 121a1 can be one or at least two. The first segment 121a1 and the second segments 121a2 can be integrally formed, simplifying the manufacturing process. Furthermore, by setting the second limiting portion 121a as a structure consisting of a first segment 121a1 and at least two second segments 121a2, the structural strength of the second limiting portion 121a is improved.

[0111] Of course, the second limiting part 121a may also include only a first part 121a1 and a second part 121a2, with the first part 121a1 and the second part 121a2 arranged intersecting each other. Preferably, the first part 121a1 and the second part 121a2 are arranged perpendicularly or approximately perpendicularly. For example, the second limiting part 121a can be in the shape of a cross or a T, which can also have good structural strength. In addition, the included angle between the first part 121a1 and the second part 121a2 can also be other angles.

[0112] like Figure 13 As shown, specifically, the second groove 115 includes a first groove segment 115a and a second groove segment 115b that are connected. When the processing box 12 is installed into the mounting cavity 111 of the body 11, the second limiting part 121a can move along the first groove segment 115a to the second groove segment 115b, and the depth of the second groove segment 115b is greater than the depth of the first groove segment 115a. As the processing box 12 is installed into the mounting cavity 111 of the body 11, the length of the second limiting part 121a extending into the second groove 115 increases. By setting the depth of the second groove segment 115b to be greater than the depth of the first groove segment 115a, it plays a role in avoiding interference between the second limiting part 121a and the inner wall of the second groove 115.

[0113] The second groove 115 also includes a transition section, which connects the first groove section 115a and the second groove section 115b. The transition section is inclined from the end of the first groove section 115a toward the beginning of the second groove section 115b, and plays a transitional guiding role for the second limiting part 121a to move from the first groove section 115a to the second groove section 115b.

[0114] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
