TECHNICAL FIELD
[0001] The utility model relates to the technical field of electronic imaging, specifically, it is a box and electronic imaging equipment that can be installed with the box. BACKGROUND
[0002] Printers are common office equipment, and common printers include inkjet printers and laser printers. Inkjet printers use ink cartridges as consumable containers to spray ink onto paper and other printing media to form text or patterns on the paper. Laser printers use toner cartridges or process cartridges as consumable containers to form text or patterns on paper and other printing media through electronic imaging.
[0003] Existing cartridges for containing toner can be divided into integrated cartridges and split cartridges. Split cartridges are provided with a developer cartridge and a drum cartridge that can be detached from each other. A developing roller is installed in the developer cartridge, and a photosensitive drum and a charging roller are installed in the drum cartridge. When the laser printer is in operation, the toner in the developer cartridge needs to be transferred to the paper, at which time the photosensitive drum needs to be in close contact with the developing roller for development. In addition, from the perspective of the stability of the developing agent, when imaging is not needed, the developing roller and the photosensitive drum need to be separated. After the photosensitive drum is separated from the developing roller, it is cleaned by a cleaning brush. Therefore, the existing developer cartridge is provided with a mechanism for separating the developer cartridge from the drum cartridge, and the laser printer is also provided with two sliders that cooperate with the separation mechanism to achieve the separation of the developer cartridge and the drum cartridge.
[0004] The separation mechanism on the existing developer cartridge includes two movable parts and a pressing unit. The pressing unit cooperates with the two movable parts to enable the two movable parts to swing within a certain angle, thereby cooperating with the two sliders to achieve the separation of the developer cartridge and the drum cartridge. However, since the sliding range is small and the swing angle of the two movable parts is also small, the installation size of the pressing unit must have high precision, and the two movable parts must be accurately matched with the pressing unit, so that the developing roller and the photosensitive drum are uniformly pressed, thereby ensuring the imaging quality.
[0005] Since the developer cartridge and the drum cartridge are easily vibrated during the process of separation and combination, which can affect the imaging quality. In order to separate and combine the developing roller of the developer cartridge relative to the photosensitive drum, and to uniformly press the developing roller on the photosensitive drum, the existing pressing unit usually uses a spring to solve this problem. However, on the one hand, the existing structure has the problem of complex structure, which leads to high production cost of the developer cartridge. On the other hand, since one movable part and one spring are respectively arranged at both ends of the developer cartridge, each movable part cooperates with one spring. Since the structures of the two movable parts are not the same, the elastic forces of the two springs are likely to be unbalanced, which can cause the two movable parts at both ends to be unevenly stressed and affect the separation and combination of the developer cartridge and the drum cartridge. The utility model discloses a box
[0006] The first purpose of the utility model is to provide a box which is simple in structure and low in production cost.
[0007] The second purpose of the utility model is to provide an electronic imaging device with the box.
[0008] To realize the first purpose of the utility model, the box provided by the utility model comprises a first slider which is detachably installed into an electronic imaging device, and the electronic imaging device is internally provided with the first slider, the box comprises a developing frame, the two ends of the developing frame are respectively provided with a first end cover and a second end cover, a developing roller is supported between the first end cover and the second end cover, a first movable piece is hinged on the first end cover, and the first movable piece is provided with a first hooking part; the first movable piece is further provided with a first blocking part, and the first end cover is provided with a first limiting part and a second limiting part; when the first slider moves towards the first movable piece and pushes the first movable piece to rotate in a first direction, the first blocking part can abut on the first limiting part to limit the rotating angle of the first movable piece in the first direction, so that the first hooking part slides into a first sliding groove of the first slider; and the first movable piece can abut on the second limiting part to limit the rotating angle of the first movable piece in a second direction, wherein the first direction is opposite to the second direction.
[0009] As can be seen from the above scheme, the first movable piece is provided with the first blocking part, and the first end cover is provided with the first limiting part and the second limiting part, the rotating angle of the first movable piece in the first direction can be limited through the cooperation of the first blocking part and the first limiting part, and the rotating angle of the first movable piece in the second direction can be limited through the second limiting part. In this way, in the process of separating and combining the developing box and the fixing device, the rotating angle of the first movable piece is limited, so that the first hooking part of the first movable piece can be smoothly installed into the first sliding groove. Through the limiting effect of the first blocking part, a spring or other pressure units are not needed, the structure of the separating structure is very simple, the assembly of the developing box is very convenient, and the production cost of the developing box is reduced.
[0010] One preferred scheme is that the electronic imaging device is provided with a driving force output piece, a plane passing through the axis line of the developing roller and the axis line of the driving force output piece constitutes a reference plane; when the first blocking part abuts on the first limiting part, the distance between the contact point of the first movable piece and the first slider and the reference plane is between 5.5 mm and 6.5 mm; and when the first movable piece abuts on the second limiting part, the distance between the contact point of the first movable piece and the first slider and the reference plane is between 9.5 mm and 10.5 mm.
[0011] Therefore, through the limiting effect of the first blocking part and the first limiting part, and the limiting effect of the second limiting part, the distance between the first movable part and the reference plane at the two limit positions is controlled within a specific size range, which can ensure that the first movable part can be smoothly installed into the first slider.
[0012] Further, the first hooking part is provided with a first guide slope on one side in the first direction; and / or the first hooking part is provided with a second guide slope on one side in the second direction.
[0013] Therefore, by setting the guide slope, the first hooking part can be smoothly slid into the first sliding groove of the first slider or slid out of the first sliding groove.
[0014] Further, the end of the first hooking part is provided with a hooking protrusion extending away from the hinge end.
[0015] By setting the hooking protrusion, the first hooking part can be prevented from sliding out of the sliding groove of the first slider during installation of the developing cartridge into the electronic imaging device.
[0016] Further, when the first blocking part abuts against the first limiting part, the first movable part is at the first limit position, and when the first movable part abuts against the second limiting part, the first movable part is at the second limit position; the rotation angle of the first movable part when rotating from the first limit position to the second limit position is between 15° and 20°.
[0017] Therefore, the rotation angle of the first movable part is limited under the limiting effect of the first limiting part and the second limiting part, avoiding that the rotation angle of the first movable part is too large to affect the cooperation between the first movable part and the first slider.
[0018] Further, the first movable part has a hinge end and a connecting part, the connecting part being connected between the hinge end and the first hooking part; along the extension direction of the connecting part, the distance between the rotation center of the hinge end and the distal end of the first hooking part is between 18 mm and 20 mm.
[0019] Further, the electronic imaging device is further provided with a second slider; the second end cover is hingedly connected with a second movable part, and the second movable part is provided with a second hooking part; the second movable part is further provided with a second blocking part, and the second end cover is provided with a third limiting part and a fourth limiting part; when the second slider moves towards the second movable part and pushes the second movable part to rotate in the first direction, the second blocking part can abut against the third limiting part to limit the rotation angle of the second movable part in the first direction, so that the second hooking part slides into the second sliding groove of the second slider; and the second movable part can abut against the fourth limiting part to limit the rotation angle of the second movable part in the second direction.
[0020] Therefore, the second blocking portion is arranged on the second movable member, and the third limiting portion and the fourth limiting portion are arranged on the second end cover, the rotation angle of the second movable member in the first direction is limited by cooperation of the second blocking portion and the third limiting portion, and the rotation angle of the second movable member in the second direction is limited by the fourth limiting portion. In this way, in the process of separating and combining the developing cartridge and the fixing device, the rotation angle of the second movable member is limited, so that the second hooking portion of the second movable member can be smoothly installed into the second sliding groove. By the limiting effect of the second blocking portion, a spring or other pressure unit is not needed, so that the separation structure is very simple, the assembly of the developing cartridge is very convenient, and the production cost of the developing cartridge is reduced.
[0021] Since the two movable members at the two ends of the developing cartridge do not need to cooperate with springs, but cooperate with the respective blocking portions and limiting portions of the same specifications to limit the two movable members, the two movable members can be smoothly cooperated with the two sliding blocks, and the problem of uneven force on the two ends of the developing cartridge caused by using two springs is avoided, so that the imaging quality is improved.
[0022] Further, the electronic imaging device is provided with a driving force output member, and a plane passing through the developing roller axis and the axis of the driving force output member forms a reference plane; when the second blocking portion abuts against the third limiting portion, the distance between the contact point of the second movable member and the second sliding block and the reference plane is between 8.5 mm and 9.5 mm; when the second movable member abuts against the fourth limiting portion, the distance between the contact point of the second movable member and the second sliding block and the reference plane is between 10.5 mm and 12 mm.
[0023] Therefore, by the limiting effect of the second blocking portion and the second limiting portion, and by the limiting effect of the second limiting portion, the distance between the second movable member and the reference plane at the two limit positions is controlled within a specific size range, so that the second movable member can be smoothly installed into the second sliding block.
[0024] Further, when the second blocking portion abuts against the third limiting portion, the second movable member is in the third limit position, and when the second movable member abuts against the fourth limiting portion, the second movable member is in the fourth limit position; the rotation angle of the second movable member from the third limit position to the fourth limit position is between 7° and 12°.
[0025] Therefore, the rotation angle of the second movable member is limited under the limiting effect of the third limiting portion and the fourth limiting portion, so as to avoid that the rotation angle of the second movable member is too large to affect the cooperation between the second movable member and the second sliding block.
[0026] To realize the second purpose, the electronic imaging device has a shell, the shell is internally provided with a box mounting position, and the box mounting position is detachably mounted with the box. BRIEF DESCRIPTION OF DRAWINGS

[0063] Referring to Figures 4 to 6A first movable part 200 is hinged on the first end cover 120, and is arranged on the side of the first end cover 120 close to the developing frame 110. The side of the first end cover 120 facing the second end cover 130 is provided with a hinge shaft 121, and the first movable part 200 is hinged on the hinge shaft 121 and can rotate around the hinge shaft 121. Further, the side of the first end cover 120 facing the second end cover 130 is also provided with a first limiting part 122 and a second limiting part 123, wherein the first limiting part 122 is a rib formed on the first end cover 120 and protruding from the surface of the first end cover 120 towards the second end cover 130, and the second limiting part 123 is arranged at the edge of the first end cover 120 and also protrudes from the surface of the first end cover 120 towards the second end cover 130.
[0064] Referring to Figures 7 to 9 , the first movable part 200 has a hinged end 201 with a through hole, and the hinged end 201 can be sleeved on the hinge shaft 121 so that the first movable part 200 rotates relative to the hinge shaft 121. The first movable part 200 is also provided with a connecting part 202 and a first hooking part 203, wherein the connecting part 202 is connected between the hinged end 201 and the first hooking part 203, and the first hooking part 203 is in the shape of a hook. The first hooking part 203 is provided with a guide slope on one side of each of the two rotation directions, for example, a first guide slope 206 on one side of the clockwise rotation direction, and a second guide slope 207 on one side of the counterclockwise rotation direction. Further, a hooking protrusion 208 extending away from the hinged end 201 is arranged at the distal end of the first hooking part 203. Referring to Figure 9 , along the extension direction of the connecting part 202, the distance D1 between the rotation center of the hinged end 201 and the distal end of the first hooking part 203 is between 18 mm and 20 mm, and is preferably 19.4 mm. Further, the length D2 of the first hooking part 203 is between 9 mm and 11 mm, and is preferably 10 mm.
[0065] The first movable part 200 is also provided with a first blocking part 210, wherein the first blocking part 210 is connected to the hinged end 201, and the first blocking part 210 is in the shape of a bend. The first blocking part 210 can abut against the first limiting part 122, as Figure 5 indicated.

[0066] When the first blocking part 210 abuts against the first limiting part 122, the first movable part 200 is in the first limit position, as Figure 10As shown. The electronic imaging device is equipped with a driving force output component arranged parallel to the developing roller. In this embodiment, the plane passing through the axis of the developing roller 115 and the axis of the driving force output component is used as the reference plane 400. When the first movable member 200 is in the first extreme position, the distance D3 between the contact point 230 of the first movable member 200 and the first slider and the reference plane 400 is between 5.5 mm and 6.5 mm, preferably 6 mm.

[0067] During the separation and assembly of the developing cartridge and the drum cartridge, the first movable member 200 can rotate around the hinge shaft 121. When the first movable member 200 rotates in the second direction, such as Figure 11 As indicated by the arrow, the first movable member 200 can abut against the second limiting member 123, at which point the first movable member 200 is in the second extreme position. From Figure 11 As can be seen, the connecting portion 202 of the first movable member 200 abuts against the second limiting member 123, thereby limiting the rotation angle of the first movable member 200 in the second direction. (Comparison) Figure 5 and Figure 11 As can be seen, the first direction and the second direction are opposite directions of rotation. For example, the first direction is counterclockwise and the second direction is clockwise.
[0068] See Figure 12 When the first movable member 200 is in the second extreme position, the distance D4 between the contact point 231 of the first movable member 200 and the first slider and the reference plane 400 is between 9.5 mm and 10.5 mm, preferably 10 mm. Furthermore, the angle β between the rotation center of the hinge end 201 of the first movable member 200 and the plane 402 of the contact point 231 and the reference plane 400 is between 26° and 30°, preferably 28°. Therefore, the rotation angle of the first movable member 200 when rotating from the first extreme position to the second extreme position is between 15° and 20°.
[0069] See Figures 13 to 16The second movable member 300 is hinged on the second end cover 130, and is arranged on the side of the second end cover 130 close to the developing frame 110. The side of the second end cover 130 facing the first end cover 120 is provided with a hinge shaft 131, and the second movable member 300 is hinged on the hinge shaft 131 and can rotate around the hinge shaft 131. In addition, the side of the second end cover 130 facing the first end cover 120 is also provided with a third limiting part 132 and a fourth limiting part 133, wherein the third limiting part 132 is a rib formed on the second end cover 130, and the third limiting part 132 protrudes from the surface of the second end cover 130 towards the first end cover 120, and the fourth limiting part 133 is arranged at the edge of the second end cover 130 and also protrudes from the surface of the second end cover 130 towards the first end cover 120.
[0070] Referring to Figure 17 and Figure 18 , the second movable member 300 has a hinged end 301, and the hinged end 301 has a through hole, and the hinged end 301 can be sleeved on the hinge shaft 131 so that the second movable member 300 rotates relative to the hinge shaft 131. The second movable member 300 is also provided with a connecting part 302 and a second hooking part 303, wherein the connecting part 302 is connected between the hinged end 301 and the second hooking part 303, and the second hooking part 303 is in the shape of a hook, and the back of the hook away from the hook-shaped opening is a flat surface 305, and the flat surface 305 and the connecting part 302 form an inclined surface 306.
[0071] The second movable member 300 is also provided with a second blocking part 310, wherein the second blocking part 310 is connected to the hinged end 301, and the second blocking part 310 is in the shape of a bend, and the end of the second blocking part 310 forms an abutting surface 311, and the second blocking part 310 can abut on the third limiting part 132, as shown in Figure 19 , the abutting surface 311 abuts on the third limiting part 132. When the second movable member 300 rotates in the first direction, as shown by the arrow in Figure 19 , the rotation angle of the second movable member 300 in the first direction can be limited by the cooperation of the second blocking part 310 and the third limiting part 132.
[0072] When the second blocking part 310 abuts on the third limiting part 132, the second movable member 300 is in the third limit position, as shown in Figure 19When the second movable member 300 is in the first limit position, the distance D5 between the contact point 331 of the second movable member 300 and the reference plane 400 is between 8.5mm and 9.5mm, preferably 9mm. In addition, when the second movable member 300 is in the third limit position, the contact point 331 of the second movable member 300 is on the plane 305, and the angle γ between the plane 305 and the reference plane 400 is between 20° and 24°, preferably 22°.
[0073] In the process of separating and combining the developing cartridge and the drum cartridge, the second movable member 300 can rotate around the hinge shaft 131. When the second movable member 300 rotates in the second direction, as indicated by the arrow direction, the second movable member 300 can abut against the fourth limiting member 133, and at this time, the second movable member 300 is in the fourth limit position. Figure 20 Figure 21 and Figure 22 It can be seen that the inclined surface 306 of the second movable member 300 abuts against the fourth limiting member 133, thereby limiting the rotation angle of the second movable member 300 in the second direction.
[0074] Referring to Figure 22 When the second movable member 300 is in the fourth limit position, the distance D6 between the contact point 332 of the second movable member 300 and the reference plane 400 is between 10.5mm and 12mm, preferably 11.1mm. When the second movable member 300 is in the fourth limit position, the contact point 332 of the second movable member 300 is on the plane 305, and the angle δ between the plane 305 and the reference plane 400 is between 29° and 33°, preferably 31°. Therefore, the rotation angle of the second movable member 300 from the third limit position to the fourth limit position is between 7° and 12°.
[0075] The process of engaging the developing cartridge with the first slider 160 and the second slider 170 will be described below. Figures 23 to 33 The electronic image forming device is provided with the first slider 160 and the second slider 170, wherein the first slider 160 is used to cooperate with the first movable member 200, and the second slider 170 is used to cooperate with the second movable member 300. The first slider 160 has a contact portion 161 and is formed with a first sliding groove 162; the second slider 170 has a contact portion 171 and is formed with a second sliding groove 172.
[0076] Referring to Figure 23 Figure 24 In the first stage of the assembly of the developing cartridge 100, the developing cartridge 100 is not in contact with the first slider 160 and the second slider 170, and the first movable member 200 is spaced apart from the first slider 160, and the second movable member 300 is spaced apart from the second slider 170, and the first movable member 200 and the second movable member 300 are free to rotate within a limited angle range.
[0077] Referring to Figure 25 When the developing cartridge 100 is in contact with the first slider 160 and the second slider 170, the developing cartridge 100 is in the second stage of cooperation with the two sliders, as shown in Figure 26 The back surface of the first hooking part 203 of the first movable member 200 is in contact with the contact part 161 of the first slider 160, and the first blocking part 210 of the first movable member 200 is in abutment against the first limiting member 122, so that the first movable member 200 cannot continue to rotate in the first direction. At the same time, as shown in Figure 27 The back surface of the second hooking part 303 of the second movable member 300 is in contact with the contact part 171 of the second slider 170, and the second blocking part 310 of the second movable member 300 is in abutment against the third limiting member 132, so that the second movable member 300 cannot continue to rotate in the first direction.
[0078] Then, as shown in Figure 28 The developing cartridge 100 continues to move towards the first slider 160 and the second slider 170, and the developing cartridge 100 is in the third stage of cooperation with the two sliders. Referring to Figure 29 However, the first blocking part 210 of the first movable member 200 is in abutment against the first limiting member 122, so that the first movable member 200 cannot continue to rotate in the first direction, and as the first movable member 160 continues to move towards the developing cartridge 100, the first hooking part 203 passes over the contact part 161 and extends into the first sliding groove 162. At the same time, as shown in Figure 30 The second hooking part 303 of the second movable member 300 also passes over the contact part 171 of the second slider 170 and extends into the second sliding groove 172.
[0079] Finally, the first hooking part 203 of the first movable member 200 is limited in the first sliding groove 162 of the first slider 160, and the second hooking part 303 of the second movable member 300 is limited in the second sliding groove 172 of the second slider 170, as shown in Figure 31 The developing cartridge 100 is in the fourth stage of cooperation with the two sliders. Referring to Figure 32, the first hooking part 203 of the first movable piece 200 slides into the first sliding groove 162 and abuts against the inner wall of the first sliding groove 162 in the first direction and the second direction, thereby limiting the first movable piece 200. In addition, due to the limiting effect of the second limiting part 123 on the first movable piece 200, the rotation angle of the first movable piece 200 in the second direction is limited, and the first movable piece 200 will not slide out of the first sliding groove 162 due to the too large rotation angle of the first movable piece 200 in the second direction. In addition, the hooking protrusion 208 is arranged on the first hooking part 203, and the hooking protrusion 208 can abut against the inner wall of the first sliding groove 162, thereby effectively preventing the first hooking part 203 from sliding out of the first sliding groove 162.
[0080] Referring to Figure 33 , the second hooking part 303 of the second movable piece 300 slides into the second sliding groove 172 and abuts against the inner wall of the second sliding groove 172 in the first direction and the second direction, thereby limiting the second movable piece 300. In addition, due to the limiting effect of the fourth limiting part 133 on the second movable piece 300, the rotation angle of the second movable piece 300 in the second direction is limited, and the second movable piece 300 will not slide out of the second sliding groove 172 due to the too large rotation angle of the second movable piece 300 in the second direction.
[0081] In the developing box 100, the first movable piece 200 and the second movable piece 300 are respectively provided with the first blocking part 210 and the second blocking part 310, a plurality of limiting parts are arranged on the first end cover 120 and the second end cover 130, so that the first movable piece 200 will not slide in the first sliding groove 162 after sliding into the first sliding groove 162, and the second movable piece 300 will not slide in the second sliding groove 172 after sliding into the second sliding groove 172, thereby realizing the positioning of the developing box 100 and the first sliding block 160 and the second sliding block 170.
[0082] Thus, the developing box 100 or the electronic imaging equipment does not need to be provided with a spring, and the first movable piece 200 and the second movable piece 300 are integral parts, for example, integrally injection molded, without the need for assembly, and the structure is simple, the assembly process of the developing box 100 is simplified, the production cost of the developing box 100 is reduced, and the assembly efficiency of the developing box 100 is improved. In addition, since the spring does not need to be arranged in the developing box 100, the problem of inconsistent spring elastic force at both ends of the developing box 100 affecting the imaging quality will not occur.
[0083] Finally, it needs to be emphasized that the above is only the preferred embodiment of the present application, and is not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
