Description

Technical Field

[0001] The present application relates to the technical field of printing equipment, and in particular to a color printer that is convenient for protecting ink cartridges. Background Art

[0002] As one of the output devices of a computer, a color printer can print the computer processing results on relevant media and make the target object show color patterns. As an important component of a color inkjet printer, the ink cartridge can directly affect the printing effect of the color inkjet printer and plays an important role in the color inkjet printer.

[0003] There is a color printer in the prior art, which includes a body, a mounting cavity is provided on the side wall of the body, an ink cartridge is provided in the mounting cavity, the ink cartridge is slidably connected to the inner wall of the mounting cavity, and can slide out of the mounting cavity. A switch door is provided at the opening of the mounting cavity, the bottom end of the switch door is rotatably connected to the body, and a locking assembly is also provided in the body, and the locking assembly is used to lock the switch door when the switch door is closed. When in use, when the switch door needs to be opened, the user controls the locking assembly to unlock the switch door, and rotates the switch door downward, so that the switch door releases the sealing of the mounting cavity, thereby allowing the user to take out the ink cartridge.

[0004] With regard to the above-mentioned related technologies, since the ink cartridge in the prior art merely relies on the inner side wall of the switch door to achieve the limitation and locking of the ink cartridge, when the user opens the switch door, the switch door will gradually release the contact with the ink cartridge, thereby releasing the sliding restriction of the switch door on the ink cartridge. This makes it easy for the ink cartridge to slide accidentally after the switch door is opened, thereby increasing the chance of the ink cartridge being damaged after sliding out of the installation cavity, affecting the normal use of the subsequent color printer, so it needs to be improved. Summary of the invention

[0005] In order to reduce the probability of accidental slipping of the ink cartridge after the switch door is opened, the present application provides a color printer that is convenient for protecting the ink cartridge.

[0006] The present application provides a color printer that is convenient for protecting ink cartridges, which adopts the following technical solution: A color printer that is convenient for protecting ink cartridges comprises a body, an ink cartridge and a switch door, wherein the ink cartridge is located in a cavity of the body and is slidably connected to the inner wall of the body, an anti-slip mechanism is also provided in the body, the anti-slip mechanism comprises an anti-slip frame and a driving component, the anti-slip frame is slidably connected to the body, and the sliding direction is not the sliding direction of the ink cartridge, one end of the anti-slip frame along its own sliding direction abuts against the outer wall of the ink cartridge, and the driving component is used to drive the anti-slip frame to slide.

[0007] By adopting the above-mentioned technical scheme, compared with the prior art, after the user opens the switch door, the restriction on the sliding of the ink cartridge is released due to the lack of a specific locking structure, which makes it easy for the ink cartridge to accidentally slide out of the body, resulting in an increased probability of damage to the ink cartridge; the present application sets an anti-slip mechanism, so that after the switch door is opened, the driving component can drive the anti-slip frame to slide, and make one end of the anti-slip frame abut against the outer wall of the ink cartridge, thereby hindering the sliding of the ink cartridge, reducing the probability of accidental sliding of the ink cartridge, and reducing the probability of damage to the ink cartridge after sliding out of the body, thereby ensuring the subsequent normal use of the present application.

[0008] Preferably, the driving assembly includes an active frame and a driven frame, the active frame is slidably connected to the body, one end of the driven frame is rotatably connected to the active frame, and the other end of the driven frame is rotatably connected to the anti-slip frame, and the anti-slip mechanism also includes a linkage assembly, and the switch door drives the active frame to slide through the linkage assembly.

[0009] By adopting the above technical scheme, the setting of the driving component enables the switch door to drive the active frame to slide through the linkage component when it is opened, so that the active frame drives the driven frame to move, and then the anti-slip frame slides in the direction close to the ink cartridge, and finally abuts against the outer wall of the ink cartridge, thereby hindering the sliding of the ink cartridge and realizing the driving of the anti-slip frame; at the same time, the setting of the transmission relationship between the switch door, the linkage component and the active frame enables the switch door to automatically slide through the linkage component when it is opened, thereby realizing the linkage between the switch door and the anti-slip frame, effectively facilitating the user's operation and ensuring the effect of hindering the sliding of the ink cartridge.

[0010] Preferably, the top end of the switch door is rotatably connected to the machine body, and the linkage assembly includes a linkage frame, one end of which is rotatably connected to the switch door, and the other end of which is rotatably connected to the active frame.

[0011] By adopting the above technical solution, the linkage frame is set so that when the switch door rotates upward, the rotation of the switch door will drive the linkage frame to move, so that the linkage frame drives the active frame to slide, and then drives the active frame to slide, thereby realizing the linkage between the switch door and the active frame, which effectively facilitates the user's operation. At the same time, the structure is relatively simple, which is convenient for relevant personnel to set up and implement.

[0012] Preferably, a locking assembly is also provided in the body, and the locking assembly includes a locking frame and a reset member. The locking frame is slidably connected to the body and is used to be inserted into the active frame when the switch door is in an open state, and the reset member is used to allow the locking frame to continue to be inserted into the active frame.

[0013] By adopting the above technical solution, the locking assembly is set so that the locking frame can be continuously inserted into the active frame when the switch door is in the open state under the elastic force of the reset member, thereby locking the active frame, effectively reducing the probability of the switch door accidentally rotating downward under its own gravity when in the open state, thereby driving the active frame to accidentally slip, and effectively ensuring the smooth contact of the anti-slip frame with the ink cartridge.

[0014] Preferably, a return spring is sleeved on the active frame, one end of the return spring abuts against the active frame, and the other end abuts against the inner wall of the body, and the return spring is used for returning the active frame to an initial position.

[0015] By adopting the above technical solution, the reset spring is set so that when the switch door is in the unlocked state, the reset spring can continue to apply elastic force to the active frame, thereby facilitating relevant personnel to open the switch door; at the same time, the presence of the reset spring can also cooperate with the locking assembly to further reduce the probability of accidental slippage of the active frame when the switch door is in the open state, thereby ensuring the smooth contact of the anti-slip frame with the ink cartridge.

[0016] Preferably, a sliding frame is provided on the anti-slip frame, the sliding frame is slidably connected to the anti-slip frame, and the sliding direction of the sliding frame is the same as the sliding direction of the anti-slip frame, the sliding frame is abutted against the outer wall of the ink cartridge, and an elastic member is also provided between the sliding frame and the anti-slip frame, and the elastic member is used for allowing the sliding frame to continuously abut against the outer wall of the ink cartridge.

[0017] By adopting the above technical solution, the setting of the sliding frame and the elastic member enables the elastic member to use its own elastic force to make the sliding frame continuously abut against the outer wall of the ink cartridge, thereby ensuring the abutment effect on the ink cartridge, and at the same time can also reduce the probability of the outer wall of the ink cartridge being damaged due to excessive force on the ink cartridge; at the same time, when the ink cartridge needs to be slid out of the body, the existence of the sliding frame and the elastic member also enables the sliding frame to slide appropriately, thereby reducing the probability of the outer wall of the ink cartridge being damaged.

[0018] Preferably, an abutment roller is further provided on one end of the sliding frame away from the anti-slip frame, the abutment roller is rotatably connected to the sliding frame, the rotation axis of the abutment roller is perpendicular to the sliding direction of the ink cartridge, and the abutment roller abuts against the outer wall of the ink cartridge.

[0019] By adopting the above technical solution, the setting of the abutment roller can transform the sliding friction between the sliding frame and the outer wall of the ink cartridge into the rolling friction between the abutment roller and the outer wall of the ink cartridge, thereby reducing the friction force on the outer wall of the ink cartridge when the ink cartridge needs to be slid out of the body, thereby effectively protecting the outer wall of the ink cartridge and reducing the probability of damage to the outer wall of the ink cartridge itself due to excessive friction.

[0020] Preferably, a recessed groove is provided on the outer wall of the ink cartridge close to the anti-dropping frame, and one end of the abutting roller is located in the recessed groove and abuts against the inner wall of the recessed groove.

[0021] By adopting the above technical solution, the recessed groove is set so that the end of the abutting roller can be located in the recessed groove and abut against the inner wall of the recessed groove, thereby increasing the hindering effect of the abutting roller on the sliding of the ink cartridge, ensuring the locking effect of the abutting roller on the ink cartridge, and effectively reducing the probability of accidental sliding of the ink cartridge.

[0022] Preferably, a switch mechanism is also provided on the machine body, and the switch mechanism includes a pressing frame, an insertion frame and a transmission assembly. The pressing frame is embedded in the machine body and is slidably connected to the machine body. The insertion frame is slidably connected to the machine body, and one end of the insertion frame is inserted in the switch door. The pressing frame drives the insertion frame to slide through the transmission assembly.

[0023] By adopting the above technical solution, the switch mechanism is set so that the plug-in rack can lock the switch door in the closed state, thereby reducing the chance of the switch door being accidentally opened. At the same time, the user can also press the pressing rack so that the pressing rack drives the plug-in rack to slide and disengage from the switch door through the transmission assembly, thereby releasing the lock on the switch door by the plug-in rack, allowing the switch door to be opened smoothly, effectively facilitating the user's operation.

[0024] Preferably, the transmission assembly includes an active rack, a transmission gear and a driven rack, the active rack is connected to the pressing frame, the driven rack is connected to the insertion frame, the transmission gear is rotatably connected to the body, and the active rack and the driven rack are both meshed with the transmission gear.

[0025] By adopting the above technical solution and the specific setting of the transmission component, the pressing frame can drive the active rack to slide together when sliding, so that the active rack drives the transmission gear to rotate, and then the transmission gear drives the driven rack and the insertion frame to slide together, thereby realizing the transmission between the pressing frame and the insertion frame, effectively facilitating the operation of relevant personnel and saving setting space.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The anti-slip mechanism is set so that after the switch door is opened, the driving component can drive the anti-slip frame to slide, and one end of the anti-slip frame is against the outer wall of the ink cartridge, thereby hindering the sliding of the ink cartridge, reducing the probability of accidental sliding of the ink cartridge, and reducing the probability of damage to the ink cartridge after sliding out of the body, thereby ensuring the subsequent normal use of this application; 2. The transmission relationship between the switch door, the linkage component and the active frame is set so that when the switch door is opened, the active frame can be driven to slide automatically through the linkage component, thereby realizing the linkage between the switch door and the anti-slip frame, effectively facilitating the user's operation and ensuring the blocking effect on the ink cartridge sliding; 3. The setting of the switch mechanism enables the plug-in frame to lock the switch door in the closed state, thereby reducing the chance of the switch door being accidentally opened. At the same time, the user can also press the pressing frame to make the pressing frame drive the plug-in frame to slide and disengage from the switch door through the transmission component, so that the plug-in frame releases the lock on the switch door, allowing the switch door to be opened smoothly, which effectively facilitates the user's operation.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application embodiment discloses a color printer that is convenient for protecting ink cartridges. Figure 1 and Figure 2The color printer for protecting ink cartridges comprises a body 1, an ink cartridge 2 and a switch door 3. An opening is formed on the side wall of the body 1. The ink cartridge 2 is located in a chamber formed by the opening and is slidably connected to the inner wall of the body 1. The switch door 3 is used to close the chamber in which the ink cartridge 2 is installed. An anti-slip mechanism 4 is also provided in the body 1. The anti-slip mechanism 4 comprises an anti-slip frame 41 and a driving component 42. The anti-slip frame 41 is slidably connected to the body 1, and the sliding direction is not the sliding direction of the ink cartridge 2. One end of the anti-slip frame 41 along its own sliding direction abuts against the outer wall of the ink cartridge 2, and the driving component 42 is used to drive the anti-slip frame 41 to slide.

[0034] Reference Figure 1 and Figure 2 The ink cartridge 2 includes a main body 21 and a base frame 22. The main body 21 is used to store ink. The base frame 22 is fixedly sleeved on the bottom end of the main body 21. The base frame 22 is slidably connected to the inner wall of the body 1, and the sliding direction is the length direction of the base frame 22 itself. The sliding path of the base frame 22 extends to the outside of the body 1.

[0035] Reference Figure 1 and Figure 2 The top of the switch door 3 is rotatably connected to the machine body 1 through a pin shaft, and the rotation axis of the switch door 3 is parallel to the horizontal plane and perpendicular to the sliding direction of the ink cartridge 2. When the switch door 3 is in a closed state, it is embedded in the side wall of the machine body 1, and the area of ​​the side wall of the switch door 3 is larger than the opening size of the ink cartridge 2, so as to fully close the opening.

[0036] Reference Figure 1 , Figure 2 and Figure 3 A switch mechanism 5 is also provided in the machine body 1, and the switch mechanism 5 is located below the bottom end of the switch door 3. The switch mechanism 5 includes a pressing frame 51, an inserting frame 52 and a transmission assembly 53. One end of the pressing frame 51 is embedded in the machine body 1 and is slidably connected to the inner wall of the machine body 1. The other end of the pressing frame 51 extends to the outside, and the side wall is flush with the side wall of the machine body 1, so that the user can press the pressing frame 51 conveniently.

[0037] Reference Figure 1 and Figure 3 Two elastic springs 54 are also sleeved on the pressing frame 51, each of which is a pressure spring. One end of each elastic spring 54 abuts against the side wall of the pressing frame 51 extending into the body 1, and the other end of each elastic spring 54 abuts against the inner wall of the body 1, so that the pressing frame 51 can be reset after being pressed.

[0038] Reference Figure 1 and Figure 3The transmission assembly 53 includes an active rack 531, a transmission gear 532 and a driven rack 533. The active rack 531 is fixedly connected to one end of the pressing frame 51 located in the body 1, and the teeth on the active rack 531 are arranged on its top wall. The transmission gear 532 is rotationally connected to the body 1 through a pin shaft, and the transmission gear 532 is meshed with the active rack 531. The driven rack 533 is located on the side of the transmission gear 532 close to the pressing frame 51, and the driven rack 533 is meshed with the transmission gear 532.

[0039] Reference Figure 1 and Figure 3 The driven rack 533 is slidably connected to the inner wall of the body 1, and the sliding direction of the driven rack 533 is perpendicular to the sliding direction of the active rack 531. The end of the driven rack 533 away from the transmission gear 532 is fixedly connected to the insertion frame 52, and the insertion frame 52 is slidably connected to the body 1, and the sliding direction is the same as the sliding direction of the driven rack 533. The end of the insertion frame 52 away from the driven rack 533 extends outward and is inserted into the bottom end of the switch door 3 to lock the switch door 3.

[0040] Reference Figure 1 and Figure 3 In the initial state, that is, when the switch door 3 closes the opening where the ink cartridge 2 is located, the insertion frame 52 is inserted into the bottom end of the switch door 3, thereby locking the switch door 3. At this time, the pressing frame 51 extends to the side wall of the outside, parallel to the side wall of the body 1. When it is necessary to open the switch door 3, the pressing block is pressed, and the pressing block drives the active rack 531 to slide, so that the active rack 531 drives the driven rack 533 to slide downward through the transmission gear 532, and then the insertion frame 52 gradually separates from the outside of the switch door 3, unlocking the switch door 3. In this process, the elastic spring 54 is gradually compressed, thereby storing elastic potential energy.

[0041] Reference Figure 2 The anti-slip mechanism 4 also includes a linkage component 43, and the linkage component 43 includes a linkage frame 431. In the embodiment of the present application, the number of the linkage frame 431, the driving component 42 and the anti-slip frame 41 is set to two, and they are arranged one by one. The two linkage frames 431 are respectively located on both sides of the switch door 3 along its own length direction.

[0042] Reference Figure 1 and Figure 2 Each driving assembly 42 includes an active frame 421 and a driven frame 422. Each active frame 421 includes two connecting parts 4211 and an intermediate part 4212. The intermediate part 4212 is located between the two corresponding connecting parts 4211 and is fixedly connected to the two corresponding connecting parts 4211. Each connecting part 4211 is slidably connected to the inner wall of the body 1, and the sliding direction is the length direction of the intermediate part 4212, that is, the sliding direction of the bottom frame 22.

[0043] Reference Figure 2 and Figure 4 One end of each linkage frame 431 is rotationally connected to the switch door 3 through a pin, and the other end of each linkage frame 431 is rotationally connected to the connection portion 4211 of the corresponding active frame 421 that is closer to the switch door 3 through a pin. One end of each driven frame 422 is rotationally connected to the connection portion 4211 of the corresponding active frame 421 that is farther away from the switch door 3 through a pin, and the other end of each driven frame 422 is rotationally connected to the corresponding anti-slip frame 41 through a pin, thereby realizing the linkage between the active frame 421 and the anti-slip frame 41.

[0044] Reference Figure 2 and Figure 4 In the initial state, that is, when the switch door 3 is in the closed state, the active frame 421 is located at the end of its own sliding path farthest from the switch door 3, and the anti-slip frame 41 is located at the bottom of its own sliding path. When the switch door 3 rotates upward, the switch door 3 drives the linkage frame 431 to move, so that the linkage frame 431 drives the active frame 421 to slide, so that the active frame 421 slides toward the switch door 3. At this time, the active frame 421 drives the anti-slip frame 41 to slide upward through the driven frame 422, so as to gradually approach the bottom frame 22.

[0045] Reference Figure 1 and Figure 2 Each intermediate portion 4212 is sleeved with a return spring 44, one end of each return spring 44 abuts against the connection portion 4211 on the corresponding active frame 421 closer to the switch door 3, and the other end of each return spring 44 abuts against the inner wall of the body 1. When the switch door 3 is in a closed state, the return spring 44 is in a compressed state, so that when the switch door 3 is unlocked, the return spring 44 can push the active frame 421 to slide, so that the switch door 3 is automatically opened, and the switch door 3 is supported, reducing the probability of the switch door 3 accidentally rotating downward.

[0046] Reference Figure 2 and Figure 4 Each anti-slip frame 41 is provided with a sliding frame 45, each sliding frame 45 is located at the top of the corresponding anti-slip frame 41, and the bottom end of each sliding frame 45 extends downward with two sliding parts 451, and each sliding part 451 is integrally formed with the corresponding sliding frame 45. The bottom end of each sliding part 451 extends downward into the corresponding anti-slip frame 41, and is slidably connected to the corresponding anti-slip frame 41, and the sliding direction is the extension direction of the sliding part 451.

[0047] Reference Figure 2 and Figure 4Each sliding portion 451 is sleeved with an elastic member 46. In the embodiment of the present application, the elastic member 46 is configured as a pressure spring. One end of each pressure spring abuts against the top wall of the corresponding anti-slip frame 41, and the other end abuts against the bottom wall of the main body 21 of the sliding frame 45. An abutting roller 47 is provided at one end of each sliding frame 45 away from the corresponding anti-slip frame 41. Each abutting roller 47 is rotatably connected to the corresponding sliding frame 45 through a pin shaft. The extending direction of the rotation axis of each abutting roller 47 is the width direction of the bottom frame 22.

[0048] Reference Figure 2 and Figure 4 Two recessed grooves 221 are also provided on the bottom wall of the bottom frame 22, and the recessed grooves 221 correspond to the abutting rollers 47 one by one. Each recessed groove 221 is located on the displacement path of the corresponding abutting roller 47, so that after the switch door 3 is opened, the abutting roller 47 can be located in the corresponding recessed groove 221, and by abutting against the inner wall of the recessed groove 221, the sliding of the bottom frame 22 is hindered, thereby reducing the probability of accidental sliding of the bottom frame 22.

[0049] Reference Figure 2 and Figure 4 When the switch door 3 is in the open state, the top of each abutting roller 47 is located in the corresponding concave groove 221 and abuts against the inner top wall of the corresponding concave groove 221. When the user pulls the bottom frame 22 to pull out the ink cartridge 2 as a whole, the abutting roller 47 and the inner wall of the concave groove 221 continue to abut, and under the push of the inner wall of the concave groove 221, the abutting roller 47 drives the sliding frame 45 to slide downward, so that the abutting roller 47 gives way to the base. When the abutting roller 47 is completely outside the concave groove 221, the top of the abutting roller 47 contacts the bottom wall of the bottom frame 22, so that the bottom frame 22 can be pulled out smoothly.

[0050] Reference Figure 1 and Figure 4 , a locking assembly 6 is also provided in the machine body 1. In the embodiment of the present application, two locking assemblies 6 are provided, and they are provided one by one with the active frame 421. Each locking assembly 6 includes a locking frame 61 and a reset member 62, and each locking frame 61 is slidably connected to the inner wall of the machine body 1. In the embodiment of the present application, the reset member 62 is provided as a pressure spring, and each of the pressure springs is sleeved on the bottom end of the corresponding locking frame 61, and the top end of each of the pressure springs is against the bottom end of the corresponding locking frame 61, and the bottom end of each of the pressure springs is against the inner wall of the machine body 1, so as to realize the reset of the locking frame 61 by elastic force.

[0051] Reference Figure 1 and Figure 4The top end of each locking frame 61 is located on the displacement path of the connecting portion 4211 of the corresponding active frame 421 that is closer to the switch door 3, so that when the switch door 3 is in the open state, the top end of the locking frame 61 can be inserted into the corresponding connecting portion 4211, thereby locking the connecting portion 4211.

[0052] Reference Figure 1 and Figure 4 The top of each locking frame 61 is set to a spherical surface, and the locking frame 61 is inserted into the groove at the bottom of the corresponding connecting part 4211, and is adapted to the spherical surface, so that when the door 3 is rotated, the connecting frame can drive the active frame 421 to slide, so that the inner wall of the groove opened at the bottom of the connecting part 4211 is against the spherical surface at the top of the locking frame 61, pushing the locking frame 61 to slide, so that the locking frame 61 releases the unlocking of the active frame 421.

[0053] The implementation principle of a color printer that is convenient for protecting ink cartridges in the embodiment of the present application is as follows: when the pressing frame 51 is pressed, the pressing frame 51 drives the locking frame 61 to slide through the transmission assembly 53, and the switch door 3 is unlocked. Under the elastic force of the reset spring 44, the active frame 421 drives the linkage frame 431 to move, so that the switch door 3 gradually rotates and opens. In this process, the active frame 421 drives the anti-slip frame 41 to slide upward through the driven frame 422, so that the abutting roller 47 on the sliding frame 45 moves into the recessed groove 221 and abuts against the inner wall of the recessed groove 221. After abutting, the anti-slip frame 41 continues to slide upward, so that the elastic member 46 is continuously compressed, increasing the elastic force applied to the sliding frame 45. When the switch door 3 is fully opened, the locking frame 61 is inserted on the active frame 421 to lock the active frame 421.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
