[0021] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0022] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is understood that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0023] The present application embodiment provides a printing device. The printing device is for example, but not limited to, a 2D UV printer, a 3D printer, etc. Figure 1 , Figure 1 It is a schematic diagram of the three-dimensional structure of a printing device provided in some embodiments of the present application.

[0024] In some embodiments, the printing device 1000 may include a body 10 and a door body 20. A printing space 101 for printing objects may be provided inside the body 10. An opening 102 connected to the printing space 101 is provided on the surface of the body 10. The door body 20 is disposed on a side of the body 10 where the opening 102 is provided. The door body 20 may be used to cover the opening 102. The door body 20 may be connected to the body 10. During the printing process, the door body 20 may cover the opening 102. Before or after printing, the printing device 1000 may remove the door body 20 so that the printed objects or accessories to be assembled into the printing space 101 may pass through the opening 102.

[0025] The printing device 1000 usually needs to close the printing space 101 when printing. Taking a 2D UV printer as an example, since UV ink has the characteristics of corrosion and volatile pungent odor, the printing device 1000 needs to close the printing space 101 when printing to prevent UV ink from splashing and odor from volatilizing. The printing device 1000 can close the printing space 101 by closing the door body 20, that is, using the door body 20 to cover the opening 102.

[0026] The problem with the printing device 1000 is that in some specific application scenarios, the door body 20 connected to the body 10 may form an obstruction. For example, in the process of printing some small objects such as mobile phone cases, water cups, refrigerator magnets and business cards, the opening and closing of the door body 20 usually does not have a negative impact, but in the process of printing larger objects, such as long-format scrolls, because their width may far exceed the size of the body 10, when printing, they need to extend from the inside of the printing space 101 through the opening 102 to the outside of the printing space 101, and at this time, the door body 20 may form an obstruction. Similarly, in the scenario of installing accessories in the printing space 101, the door body 20 may also form an obstruction.

[0027] To solve this technical problem, the printing device 1000 provided in some embodiments of the present application may further include a connecting mechanism 30. The machine body 10 and the door body 20 may be connected via the connecting mechanism 30. The connecting mechanism 30 is a detachable mechanism, so that the door body 20 can be detachably connected to the machine body 10, so that the printing device 1000 can detach the door body 20 from the base.

[0028] Through the above design, the printing device 1000 can separate the door body 20 from the body 10 to avoid the door body 20 forming an obstruction when the door body 20 may form an obstruction, so that the printing device 1000 can be installed with more types of accessories and can also print objects whose sizes exceed the range of the body 10, so that the printing device 1000 can have more printing methods.

[0029] Please combine Figure 1 See also Figure 3 and Figure 4 , Figure 3 is a schematic diagram of the structure of a printing device in a closed state provided by some embodiments of the present application, Figure 4 yes Figure 3 A schematic diagram of the structure of the printing device in an open state in the embodiment.

[0030] In some embodiments, the body 10 may include a first surface 11 and a second surface 12 opposite to each other. The first surface 11 and the second surface 12 may be provided with at least one opening 102 respectively. The opening 102 on the first surface 11 may be connected to the opening 102 on the second surface 12 through the printing space 101. The printing device 1000 may include two door bodies 20, which are respectively provided on the first surface 11 and the second surface 12 of the body 10, and may be used to cover the opening 102 on the first surface 11 and the opening 102 on the second surface 12 respectively.

[0031] In the embodiment of the present application, the printing device 1000 may also include only one door body 20, or include more than two door bodies 20 provided on the same machine body 10. The multiple door bodies 20 may be provided on different sides of the machine body 10. At least part of the multiple door bodies 20 may also be provided on the same side of the machine body 10. Each door body 20 of the printing device 1000 may be connected to the machine body 10 via at least one connecting mechanism 30.

[0032] In some application scenarios, the printing device 1000 needs to print objects or install accessories of large size, and the printing device 1000 can remove at least one door body 20 on the body 10, so that the printed objects or installation tools can pass through one or more openings 102, so as to facilitate the printing of the printing device 1000 or the installation of internal accessories. Optionally, when printing or installing, the printing device 1000 can open both the doors 20 on the first surface 11 and the second surface 12, so that the opening 102 on the first surface 11, the printing space 101, and the opening 102 on the second surface 12 cooperate to form a channel, which can effectively expand the scope of application of the printing device 1000.

[0033] It should be understood that the terms "including" and "having" and any variations thereof used in the present specification and the appended claims are intended to cover non-exclusive inclusions.

The second connection member 32 may be disposed on the machine body 10. The machine body 10 and the door body 20 may be connected via the first connection member 31 and the second connection member 32. The first connection member 31 and the second connection member 32 may be detachably connected, for example but not limited to a snap connection, a pin connection, etc., so that the door body 20 may be separated from the machine body 10.

[0036] The embodiment of the present application utilizes a detachably connected first connector 31 and a second connector 32 to connect the body 10 and the door body 20 of the printing device 1000 together, so that the printing device 1000 can separate the door body 20 from the body 10 by disassembling the first connector 31 and the second connector 32, so that the door body 20 can be removed from the body 10 in a specific application scenario to avoid obstruction caused by the door body 20.

[0037] In some embodiments, the first connector 31 and the second connector 32 may be two independent structural members, which may be directly or indirectly connected to the machine body 10 and the door body 20, respectively. In other embodiments, at least one of the first connector 31 and the second connector 32 may also be fixed to the machine body 10 and the door body 20, and the fixing method may be a fixed connection or an integral molding.

[0039] In some embodiments, the connection mechanism 30 may include a movable member 33. The movable member 33 may be disposed between the machine body 10 and the door body 20, and may be movably connected to one of them and inactively connected to the other, so that the door body 20 may move relative to the machine body 10. Optionally, the above-mentioned movable connection may be a rotational connection, which may be realized, for example but not limited to, by a shaft, so that the door body 20 may be rotatably opened or closed relative to the machine body 10. In other embodiments, the door body 20 may also be opened or closed relative to the machine body 10 by translation or other movable methods.

[0040] In some embodiments, the movable member 33 can be movably connected to the body 10. The second connecting member 32 can be disposed on the movable member 33, so as to be disposed on the body 10 through the movable member 33. The movable member 33 can be detachably connected to the first connecting member 31 through the second connecting member 32, so that the door body 20 can move relative to the body 10. In some embodiments, the body 10 can be provided with a receiving groove 103. When the door body 20 is closed relative to the body 10, the movable member 33 can be at least partially received in the receiving groove 103. In some embodiments, the connecting mechanism 30 can be connected to the side of the body 10 and the side of the door body 20, for example Figure 1 As shown, the receiving groove 103 is connected between the bottom side of the machine body 10 and the bottom side of the door body 20. The receiving groove 103 can be opened at the bottom of the machine body 10.

[0041] In some embodiments, the connection mechanism 30 may include an unlocking member 34. The unlocking member 34 may be connected to one of the first connection member 31 and the second connection member 32 to trigger the separation of the first connection member 31 from the second connection member 32. In a specific application scenario, the printing device 1000 may separate the first connection member 31 from the second connection member 32 by triggering the unlocking member 34, thereby separating the door body 20 from the machine body 10, so that the printing device 1000 can quickly disassemble the door body 20. The unlocking member 34 may be triggered by, for example, but not limited to, pressing, pushing, twisting, touching, etc.

[0042] In some embodiments, the unlocking member 34 may be disposed on the door body 20 and connected to the first connecting member 31, so that the unlocking member 34 may be used to trigger the first connecting member 31 to separate the first connecting member 31 from the second connecting member 32. In some embodiments, the connecting mechanism 30 may include a first fixing member 35, and the first fixing member 35 may be fixed to the door body 20. The fixing method of the first fixing member 35 to the door body 20 is, for example but not limited to, nailing, riveting, welding, integral molding, etc. The first connecting member 31 may be disposed on the first fixing member 35, and disposed on the door body 20 through the first fixing member 35.

[0043] In some embodiments, the connection mechanism 30 may be as follows: Figure 5 As shown, it includes a first connection group 100 and a second connection group 200.

[0044] See also Figures 5 to 7 , Figure 6is a three-dimensional structural schematic diagram of a connection mechanism provided in some embodiments of the present application, Figure 7 It is a schematic diagram of the cross-sectional structure of the connection mechanism provided in some embodiments of the present application.

[0045] In some embodiments, the first connecting member 31 may include a first clamping portion 311. The second connecting member 32 may include a second clamping portion 321. The first clamping portion 311 may be clamped with the second clamping portion 321. Optionally, the first connecting member 31 may move relative to the second connecting member 32 along the first direction X to separate the first clamping portion 311 from the second clamping portion 321. The unlocking member 34 may be connected to the first connecting member 31 to push the first connecting member 31 to move along the first direction X. In some application scenarios, the printing device 1000 may press the unlocking member 34 so that the unlocking member 34 pushes the first connecting member 31 to move along the first direction X, thereby separating the first connecting member 31 from the second connecting member 32, so as to separate the door body 20 from the machine body 10.

[0046] The first clamping portion 311 and the second clamping portion 321 may be two engaging tongues. The first clamping portion 311 and the second clamping portion 321 may abut against each other in a direction perpendicular to the first direction X to realize interlocking, so that the printing device 1000 can push the first connecting member 31 to move in the first direction X to release the interlocking state of the first clamping portion 311 and the second clamping portion 321 and realize separation of the two.

[0047] In some embodiments, the connection mechanism 30 may include a first restoring member 110. The first restoring member 110 may abut against the first connection member 31, and is used to provide a restoring force for the first connection member 31 to move in the second direction Y when the first connection member 31 moves in the first direction X. The second direction Y is opposite to the first direction X. The first restoring member 110 may abut against an end of the first connection member 31 away from the unlocking member 34. The first restoring member 110 may be connected to the first connection member 31, and the connection method may be, for example but not limited to, snap connection, bonding, etc., to prevent the first restoring member 110 from being separated from the first connection member 31. In some embodiments, the first restoring member 110 may be a spring, so that when the first connection member 31 moves in the first direction X, the first restoring member 110 may be compressed by force, and may use its elastic restoring characteristics to provide the first connection member 31 with a restoring force in the second direction Y, so as to achieve the reset of the first connection member 31 and the unlocking member 34. In other embodiments, the first restoring member 110 may also be other components, such as a compression spring.

[0048] The first connecting member 31 may be movably connected to the first fixing member 35. While being limited to the first fixing member 35, the first connecting member 31 may move relative to the first fixing member 35 along the first direction X or the second direction Y. The first restoring member 110 may be located between the first connecting member 31 and the first fixing member 35, and respectively contact the first connecting member 31 and the second fixing member 220.

[0049] In some embodiments, the first connecting member 31 may include a triggering portion 312 connected to the unlocking member 34. The first restoring member 110 may respectively abut against one end of the triggering portion 312 away from the unlocking member 34 and the first fixing member 35. In some embodiments, the first restoring member 110 may abut against the first wall 351 of the first fixing member 35. The first wall 351 is a wall of the first fixing member 35 directly opposite to the first connecting member 31 in the first direction X. The first wall 351 may be located on the side of the first connecting member 31 away from the unlocking member 34. Optionally, a boss may be provided on the first wall 351, and one end of the first restoring member 110 may be sleeved on the boss on the first wall 351. A boss may be provided on the triggering portion 312, and the other end of the first restoring member 110 may be sleeved on the boss on the triggering portion 312. The boss on the triggering portion 312 may protrude along the first direction X, and the boss on the first wall 351 may protrude along the second direction Y.

[0050] In some embodiments, a housing space 301 may be provided inside the first fixing member 35. The first connecting member 31 may be accommodated in the housing space 301. The housing space 301 may be formed by enclosing a plurality of walls of the first fixing member 35. The first fixing member 35 may include a second wall 352 opposite to the first wall 351. A telescopic opening 302 may be provided on the second wall 352. The telescopic opening 302 is a through hole. The unlocking member 34 may be passed through the telescopic opening 302 and connected to the first connecting member 31 accommodated in the housing space 301. Among them, one end of the unlocking member 34 away from the first connecting member 31 is located outside the housing space 301, and the size may be larger than the aperture of the telescopic opening 302, so as to prevent the unlocking member 34 from being completely sunk into the housing space 301 when moving along the first direction X.

[0051] After the first connecting member 31 is separated from the second connecting member 32, the restoring force applied by the first restoring member 110 to the first connecting member 31 can move the first connecting member 31 and the unlocking member 34 along the second direction Y, so that the unlocking member 34 is raised relative to the second wall 352 again. The unlocking member 34 can be used as an unlocking button of the connecting mechanism 30. When the door body 20 needs to be removed, the printing device 1000 can separate the door body 20 from the machine body 10 by pressing the unlocking member 34.

[0052] In some embodiments, an operation port 303 may be provided on the side of the first fixing member 35 facing the door body 20, and the operation port 303 is connected to the accommodating space 301. The opening of the operation port 303 can be used to observe, install, disassemble or adjust the internal structure of the accommodating space 301 on the one hand, and can also reduce the material used for the first fixing member 35 to save costs on the other hand. In some application scenarios, when the matching structure of the unlocking member 34, the first connecting member 31 and the first restoring member 110 fails, for example, when the first restoring member 110 is displaced or the restoring force is weakened, the printing device 1000 can realize external adjustment of the matching structure through the operation port 303 without disassembling and reassembling the entire connecting mechanism 30.

The limiting portion 350 may be provided on the inner surface of the wall body connected between the first wall body 351 and the second wall body 352. The limiting portion 350 may abut against the first connecting member 31 to limit the first connecting member 31 from moving in a direction perpendicular to the first direction X.

[0055] The limiting portion 350 may abut against a side of the first connecting member 31 toward the door body 20 to limit the movement of the first connecting member 31 toward the door body 20. Optionally, the limiting portion 350 may extend along the first direction X. The limiting portion 350 may be a strip-shaped protrusion disposed on the inner wall of the first fixing member 35. The limiting portion 350 may be used to guide the moving direction of the first connecting member 31. The first connecting member 31 abutting against the limiting portion 350 may move along the limiting portion 350 toward the first direction X or the second direction Y. The first connecting member 31 may achieve a movable connection with the first fixing member 35 by abutting against the limiting portion 350.

[0056] In some embodiments, the first connecting member 31 may include a substrate 313. The triggering portion 312 may be convexly disposed on a side of the substrate 313 facing the door body 20. The first clamping portion 311 may be convexly disposed on the other opposite side of the substrate 313, that is, on a side of the substrate 313 facing away from the door body 20. The limiting portion 350 may abut against a side of the substrate 313 facing the door body 20. The substrate 313 may be a strip plate adapted to the limiting portion 350.

The printing device 1000 can also install the first restoring member 110 into the accommodating space 301 through the operation opening 303, and make the first restoring member 110 connected to the first connecting member 31 and the first fixing member 35. After the first connecting member 31 is installed into the accommodating space 301, the unlocking member 34 can be installed on the first fixing member 35 through the telescopic opening 302, and connected to the first connecting member 31.

[0060] like Figure 7 As shown, the second connecting member 32 can be accommodated in the accommodating space 301. The second connecting member 32 can be installed in the accommodating space 301 through the installation port 304, and can be detachably linked with the first connecting member 31. The movable member 33 can be fixedly connected to the side of the second connecting member 32 away from the first connecting member 31, so that the second connecting member 32 can move synchronously with the movable member 33. Among them, the connection method between the movable member 33 and the second connecting member 32 is, for example but not limited to, clamping, nailing, welding, etc. In other embodiments, the second connecting member 32 can also be partially accommodated in the accommodating space 301, or the second connecting member 32 can be accommodated in the accommodating space 301 together with part of the movable member 33. Optionally, a limiting groove for accommodating the second connecting member 32 can also be provided on the inner wall of the first fixing member 35 exposed to the accommodating space 301, and its groove wall can abut against the second connecting member 32.

[0061] See also Fig.10 and Fig.11 , Fig.10 is a schematic diagram of a three-dimensional structure of a part of the connecting mechanism provided in some embodiments of the present application in a first state, Fig.11 yes Fig.10 Schematic diagram of the three-dimensional structure of a part of the connecting mechanism in the second state of the embodiment. The part of the connecting mechanism 30 may be the first connecting group 100 mentioned above.

[0062] The first state may be a state where the first connector 31 of the connection mechanism 30 is connected to the second connector 32, corresponding to the connection between the door body 20 and the machine body 10. The second state may be a state where the first connector 31 of the connection mechanism 30 is separated from the second connector 32, corresponding to the separation between the door body 20 and the machine body 10. In some embodiments, the connection mechanism 30 may push the first connector 31 to move along the first direction X through the unlocking member 34, so as to move from the first direction X to the second direction X. Fig.10 The first state shown switches to Fig.11 The second state is shown.

[0063] In some embodiments, the first wall 351 of the first fixing member 35 may be provided with an entrance 305. The size of the entrance 305 is such that an end of the first connecting member 31 close to the first wall 351 can pass through. In other words, the size of the entrance 305 is larger than the size of the end of the first connecting member 31 close to the first wall 351. In some embodiments, the entrance 305 is opened in the area of ​​the first wall 351 that is directly opposite to the base plate 313 and the first clamping portion 311 of the first connecting member 31, and the size of the entrance 305 is such that the base plate 313 and the first clamping portion 311 of the first connecting member 31 can pass through.

[0064] The first connecting member 31 can be partially inserted into or even pass through the entrance 305 during the process of moving along the first direction X to separate from the second connecting member 32, so that the first fixing member 35 does not need to provide an excessively large accommodating space 301, and the first connecting member 31 can be prevented from colliding with the first wall 351, which is beneficial to reducing the required volume of the first fixing member 35.

[0065] Optionally, a plurality of first clamping portions 311 may be provided on the side of the base plate 313 of the first connecting member 31 facing away from the door body 20. The plurality of first clamping portions 311 may be arranged at intervals along the first direction X. The stopper 120 may be located between two adjacent first clamping portions 311 to limit the moving distance of the first connecting member 31 along the first direction X. When the first connecting member 31 moves along the first direction X to a distance sufficient to separate from the second connecting member 32, the stopper 120 may contact the first clamping portion 311 to prevent the first connecting member 31 from further moving along the first direction X, thereby preventing the first connecting member 31 from falling off from the entrance 305.

[0066] Please combine Figure 2 See also Fig.12 and Fig.13 , Fig.12 is a three-dimensional structural schematic diagram of a connection mechanism provided in some embodiments of the present application, Fig.13 yes Fig.12 Schematic diagram of the exploded structure of the connection mechanism in the embodiment. As described above, in some embodiments of the present application, the first connection member 31 can be moved along the first direction X under the push of the unlocking member 34 to separate from the second connection member 32, the movable member 33 and the second connection member 32 can be located on the body 10, and the first connection member 31 and the components connected thereto are located on the door body 20, and the door body 20 can be separated from the body 10.

[0067] In some embodiments, the connecting mechanism 30 may include a second restoring member 210. The second restoring member 210 may resist the movable member 33, and is used to provide the movable member 33 with a force to return to the first position when the movable member 33 moves from the first position to the second position relative to the body 10. The first position is the position of the movable member 33 when the door body 20 is closed relative to the body 10. It can be understood that when the door body 20 is opened relative to the body 10, the movable member 33 moves from the first position to the second position. In some embodiments, the movable member 33 can be rotatably connected to the body 10, and the second restoring member 210 can be a structural member such as a torsion spring that can provide torque to the movable member 33. In other embodiments, the second restoring member 210 can also be a component of a mechanism that can be used to provide a restoring force to the movable member 33.

[0068] Through the above design, when the first connecting member 31 is separated from the second connecting member 32, the second restoring member 210 can provide a force for the movable member 33 to move toward the first position, so as to achieve the reset of the movable member 33 and the second connecting member 32. In addition, during the process of the door body 20 opening relative to the machine body 10, the force of the second restoring member 210 on the movable member 33 can also serve as a buffer force.

[0069] In certain application scenarios, the printing device 1000 can open the door 20 relative to the machine body 10, and then trigger the unlocking member 34, so that the second connecting member 32 and the movable member 33 can automatically rebound under the action of the second restoring member 210. After releasing the unlocking member 34, the unlocking member 34 and the first connecting member 31 can automatically rebound under the action of the first restoring member 110. In other application scenarios, the second connecting member 32 separated from the first connecting member 31 can be driven by the movable member 33 to move to connect with the first connecting member 31, so as to realize the connection between the door 20 and the machine body 10.

[0070] In some embodiments, the connection mechanism 30 may include a second fixing member 220. The second fixing member 220 is fixed to the body 10, and the fixing method is, for example, but not limited to, nailing, welding, integral molding, etc. The movable member 33 can be movably connected to the second fixing member 220 to achieve a movable connection with the body 10. The second restoring member 210 can resist the movable member 33 and the second fixing member 220 to provide the movable member 33 with a force to return to the first position when the movable member 33 moves from the first position to the second position relative to the body 10.

[0071] In some embodiments, the printing device 1000 may include a rotating shaft 230, and the movable member 33 may be rotatably connected to the second fixed member 220 via the rotating shaft 230. The rotating shaft 230 may be a structural member independent of the movable member 33 and the second fixed member 220, or may be an integral structure with one of the movable member 33 and the second fixed member 220. The following description is based on the example that the rotating shaft 230 is an independent structural member. The second return member 210 may be sleeved on the rotating shaft 230, and the two ends thereof may respectively contact the movable member 33 and the second fixed member 220. At least one of the second fixed member 220 and the movable member 33 may be provided with a groove or a convex portion for positioning and limiting the second return member 210.

[0072] See also Figure 12 to Figure 14 , Fig.14 yes Fig.12 Another exploded structural diagram of the connecting mechanism in the embodiment.

[0073] In some embodiments, the rotating shaft 230 can be inserted into one of the movable member 33 and the second fixed member 220 to form a rotational fit, and can rotate synchronously with the other one. For example, the rotating shaft 230 can rotate synchronously with the movable member 33, and is inserted into the second fixed member 220 to form a rotational fit, so that the movable member 33 and the rotating shaft 230 can rotate together relative to the second fixed member 220. For another example, the rotating shaft 230 can rotate synchronously with the second fixed member 220, and is inserted into the movable member 33 to form a rotational fit, so that the movable member 33 can rotate relative to the rotating shaft 230.

[0074] The movable member 33 can be rotatably connected to the second fixing member 220 via the rotating shaft 230 to realize a movable connection with the machine body 10. The second restoring member 210 can be sleeved on the rotating shaft 230, and the two ends thereof respectively contact the movable member 33 and the second fixing member 220, so that when the movable member 33 rotates relative to the second fixing member 220, the second restoring member 210 can provide a restoring force for the movable member 33.

[0075] In some embodiments, the synchronous rotation of the rotating shaft 230 and one of the movable member 33 and the second fixed member 220 can be achieved by fixing the rotating shaft 230 to the one, for example, the rotating shaft 230 and the one are integrally formed.

[0076] In other embodiments, the synchronous rotation can be achieved by setting a limit structure on the rotating shaft 230 and the movable member 33 in the rotation direction. Fig.13 As shown, the movable member 33 may be provided with an insertion hole 201, and the insertion hole 201 is a hole whose hole wall has a planar portion, such as a flat hole. The insertion hole 201 may be a through hole or a blind hole. The rotating shaft 230 may be inserted into the insertion hole 201 and adapted to the insertion hole 201, for example, the outer periphery of the rotating shaft 230 may have a planar portion opposite to the planar hole wall of the insertion hole 201, so that the rotating shaft 230 and the movable member 33 can rotate synchronously.

[0077] The printing device 1000 may further include a damping pad 240. At least one damping pad 240 is sleeved on the rotating shaft 230 and contacts at least one of the movable member 33 and the second fixed member 220, and is used to increase the rotation damping of the movable member 33 relative to the second fixed member 220. Rotation damping refers to the obstruction to the rotation of an object due to factors such as air resistance and friction during the rotation of the object. The damping pad 240 may be a soft pad with a rough surface, which may increase friction through contact and compression.

[0078] The specific position of the damping pad 240 can be set according to actual conditions. For example, the damping pad 240 can be set between the movable part 33 and the second fixed part 220, and abut against the two to increase the friction when the two rotate relative to each other. For another example, one side of the damping pad 240 abuts against the movable part 33 or the second fixed part 220 that forms a rotational fit with the rotating shaft 230, and the other side abuts against another entity structure to increase the rotation damping. Optionally, the entity structure is a part of the rotating shaft 230 or a structural member fixed to the rotating shaft 230.

[0079] In some embodiments, the rotating shaft 230 may include a rotating portion 231 and a protruding portion 232. The protruding portion 232 may be protruding from the outer peripheral surface of the rotating portion 231, as the above-mentioned physical structure for resisting the damping gasket 240. The following is an example in which the rotating shaft 230 rotates synchronously with the movable member 33 and forms a rotational fit with the second fixed member 220. The rotating portion 231 may be inserted through the second fixed member 220 and the movable member 33. The protruding portion 232 may be located between the second fixed member 220 and the movable member 33. The second return member 210 may be sleeved on the protruding portion 232. Among them, the portion of the rotating portion 231 located on one side of the protruding portion 232 may be inserted through the movable member 33, and the portion of the rotating portion 231 located on the other side of the protruding portion 232 may be inserted through the second fixed member 220.

[0080] At least one damping pad 240 can be sleeved on the rotating part 231 and abut against the second fixing part 220 to increase the friction force when the second fixing part 220 and the rotating shaft 230 rotate relative to each other, and is used to provide damping force for the movable part 33 to rotate relative to the second fixing part 220. Among them, at least one groove or convex portion can be provided on the side of the damping pad 240 facing the second fixing part 220 to increase the friction force between the damping pad 240 and the second fixing part 220. At least one groove or convex portion can also be provided on the side of the second fixing part 220 facing the damping pad 240. It can be understood that in other embodiments, the surface of the damping pad 240 can also be provided with grooves or convex portions to increase the friction force, and the same is true for the structural parts that abut against the damping pad 240.

[0081] The damping gasket 240 can be located between the second fixing member 220 and the protrusion 232, and abut against the second fixing member 220 and the protrusion 232. The second fixing member 220 and the protrusion 232 can respectively squeeze the opposite sides of the damping gasket 240. The damping gasket 240 can also be located on the side of the second fixing member 220 away from the protrusion 232, and abut against the second fixing member 220. The second fixing member 220 can cooperate with other structural members to squeeze the opposite sides of the damping gasket 240. Of course, a plurality of damping gaskets 240 can also be distributed on one side of the first fixing member 35 facing the protrusion 232, and the other side facing away from the protrusion 232, and respectively abut against the first fixing member 35.

[0082] The damping pad 240 may be provided with an insertion hole 201 for the rotating part 231 to be inserted. The rotating part 231 may be inserted into the damping pad 240 through the insertion hole 201, so that the damping pad 240 can rotate synchronously with the rotating shaft 230. Compared with the conventional circular hole and cylindrical rotational fit, the above design can achieve the fixation of the damping pad 240 and the rotating part 231 during rotation to prevent slippage.

[0083] The printing device 1000 may further include an adjusting member 250 and an elastic gasket 260. The number of the elastic gasket 260 may be multiple. The elastic gasket 260 may be sleeved on the rotating shaft 230. The adjusting member 250 may be threadedly connected to the end of the rotating shaft 230 and abut against the elastic gasket 260. The adjusting member 250 may be used to control the rotation damping by adjusting the extrusion force on the elastic gasket 260. It can be understood that within a certain range, the greater the extrusion force on both sides of the damping gasket 240, the greater the rotation damping that can be provided. The adjusting member 250 is threadedly connected to the rotating shaft 230, and the extrusion force on the elastic gasket 260 can be increased by tightening, thereby increasing the extrusion force on the damping gasket 240 to increase the rotation damping; the adjusting member 250 may also reduce the extrusion force on the elastic gasket 260 by loosening, thereby reducing the rotation damping.

[0084] In some embodiments, the end of the rotating portion 231 of the rotating shaft 230 located on the side of the protruding portion 232 away from the movable member 33 may be provided with a thread. The adjusting member 250 may be provided with a thread that matches the end of the rotating portion 231 provided with a thread. The adjusting member 250 may be a nut. The adjusting member 250 may be connected to the end of the rotating portion 231 provided with a thread, so that the printing device 1000 can adjust the tightness by controlling the number of rotations of the adjusting member 250 on the rotating portion 231, so as to adjust the damping of the rotating shaft 230.

[0085] Optionally, the elastic gasket 260 may be an inwardly concave elastic structural member having an arc surface. The elastic gasket 260 may be sleeved on the rotating portion 231 and located between the adjusting member 250 and the second fixing member 220. The printing device 1000 may include a plurality of elastic gaskets 260, for example Fig.13 and Fig.14 The two pairs of elastic gaskets 260 are shown. The multiple elastic gaskets 260 can be arranged in sequence, and the arc surfaces of two adjacent elastic gaskets 260 face opposite directions, so that the multiple elastic gaskets 260 can be elastically deformed along the axial direction of the rotating shaft 230.

[0086] Optionally, the printing device 1000 may further include a flat gasket 270 disposed between the adjusting member 250 and the elastic gasket 260. The flat gasket 270 may be sleeved on the rotating shaft 230 and contact the adjusting member 250. The flat gasket 270 may be provided with the above-mentioned insertion opening for the rotating portion 231 to be inserted. Each elastic gasket 260 may be located between the flat gasket 270 and the damping gasket 240. The flat gasket 270 and the damping gasket 240 may contact the elastic gasket 260 respectively. When the number of rotations of the adjusting member 250 on the rotating shaft 230 increases, the extrusion force on the elastic gasket 260 increases and elastic compression occurs, thereby increasing the rotation damping of the rotating shaft 230. When the number of rotations of the adjusting member 250 on the rotating shaft 230 decreases, the extrusion force on the elastic gasket 260 decreases and elastic rebound occurs, thereby reducing the rotation damping of the rotating shaft 230.

[0087] It is understandable that the positions of the adjusting member 250 and the elastic gasket 260 are not limited to the above-mentioned embodiment, and can be adjusted according to actual conditions. For example, in an embodiment where the rotating shaft 230 and the movable member 33 form a rotational fit, the adjusting member 250 and the elastic gasket 260 can be arranged at one end of the rotating shaft 230 passing through the movable member 33.

[0088] Through the above design, the printing device 1000 can make the movable member 33 receive sufficient damping force when rotating relative to the second fixing member 220, so that it will not rotate too quickly. In some embodiments, the connecting mechanism 30 is arranged at the bottom of the door body 20 and the machine body 10. The printing device 1000 can realize the slow descent of the door body 20 when opening through the above design, and prevent the door body 20 from being damaged due to rapid falling, which is conducive to improving the safety of the printing device 1000. The printing device 1000 can also adjust the damping force received by the movable member 33 when rotating relative to the second fixing member 220 through the above design, so that the printing device 1000 can adjust the speed of opening and closing of the door body 20 relative to the machine body 10 to a suitable value as needed.
