DETAILED DESCRIPTION

[0046] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0047] Please refer to Figures 1 to 3 A printer 100 provided by an embodiment of the present application is shown in FIG. 1. The printer 100 includes a core support 10, a back plate 20, a face plate 30, an elastic member 40, and a hook handle assembly 50. The back plate 20 and the face plate 30 are connected to the core support 10. The face plate 30 is arranged opposite to the back plate 20. The face plate 30 is provided with a heating print head 31 on a side opposite to the back plate 20. The elastic member 40 is compressed between the back plate 20 and the face plate 30. One end of the elastic member 40 is connected to the back plate 20, and the other end of the elastic member 40 is connected to the face plate 30. The hook handle assembly 50 is integrally formed with the back plate 20. Heat generated by the heating print head 31 can be sequentially transmitted to the hook handle assembly 50 along the elastic member 40 and the back plate 20, so that the heating print head 31 can be rapidly cooled.

[0048] Optionally, the core support 10 can provide support for the face plate 30 and the back plate 20, so that the face plate 30 and the back plate 20 can be mounted on the core support 10, and the face plate 30 and the back plate 20 are oppositely spaced, and the heating print head 31 is integrated on the side of the face plate 30 away from the back plate 20, and when the printer 100 is printing, the heating print head 31 can be in contact with the carbon ribbon, so that the heat generated by the heating print head 31 can be transmitted to the carbon ribbon, and the carbon powder on the carbon ribbon is fused by heat and adheres to the surface of the printing paper under the action of pressure, thereby realizing printing.

[0049] In order to ensure that the heating print head 31 can be in uniform contact with the carbon ribbon, an elastic member 40 in a compressed state can be arranged between the back plate 20 and the face plate 30, the elastic member 40 can generate a continuous pre-tightening force of 0.5N-1.5N, and drive the heating print head 31 to be in uniform contact with the carbon ribbon, in addition, the elastic member 40 can be a metal spring, and the elastic member 40 can act as a heat conduction medium to transmit the heat generated by the heating print head 31 to the back plate 20, so that the heat generated by the heating print head 31 can be uniformly distributed, thereby improving the printing efficiency, and the hook handle assembly 50 can be integrally formed with the back plate 20, so that the back plate 20 can be moved by the hook handle assembly 50.

[0050] When the printer 100 starts to work, the heating print head 31 can heat the carbon ribbon to realize printing, the heat generated by the heating print head 31 can be transmitted to the elastic member 40 by the face plate 30, and then transmitted to the back plate 20 by the elastic member 40, and then transmitted to the hook handle assembly 50 by the back plate 20, since the back plate 20 and the hook handle assembly 50 are integrally formed, the heat of the back plate 20 can be directly transmitted to the hook handle assembly 50 by molecular vibration, thereby improving the heat conduction efficiency, so that the heating print head 31 can be quickly cooled, if the back plate 20 and the hook handle assembly 50 are not integrally formed, but are connected through a transmission structure, then in the process of transmitting the heat of the back plate 20 to the hook handle assembly 50, the heat resistance effect may be caused by the air interface, thereby reducing the heat conduction efficiency, resulting in a decrease in the heat dissipation efficiency of the heating print head 31.

[0051] In the embodiment, the back plate 20 and the hook handle assembly 50 can be made of high-thermal-conductivity materials, such as aluminum alloy, zinc alloy, etc., so as to ensure that the heat can be efficiently transmitted, thereby improving the heat dissipation efficiency.

[0052] Please refer to Figures 2 to 4In some embodiments, the core support 10 comprises a first side plate 11 and a second side plate 12, the first side plate 11 and the second side plate 12 are spaced apart along the width direction of the printer 100, the back plate 20 is rotatably installed between the first side plate 11 and the second side plate 12, the clamping handle assembly 50 is located between the first side plate 11 and the second side plate 12, and the clamping handle assembly 50 comprises a first clamping portion 51 and a second clamping portion 52, the first clamping portion 51 and the second clamping portion 52 are connected to opposite sides of the back plate 20, respectively, the first clamping portion 51 is opposite to and spaced apart from the first side plate 11, and the second clamping portion 52 is opposite to and spaced apart from the second side plate 12.

[0053] It can be understood that the core support 10 comprises the first side plate 11 and the second side plate 12 which are spaced apart along the width direction of the printer 100, a stable installation space can be formed between the first side plate 11 and the second side plate 12, the panel 30, the back plate 20 and the clamping handle assembly 50 can be arranged in the installation space, the space utilization can be improved, thereby reducing the volume of the printer 100, and the opposite sides of the back plate 20 along the width direction can be rotatably connected to the first side plate 11 and the second side plate 12, respectively, so that the back plate 20 can be rotatably connected to the core support 10, and the back plate 20 can be easily rotated relative to the core support 10 by the clamping handle assembly 50.

[0054] It should be noted that the printer 100 further comprises a cover and a main machine, the core support 10 can be fixed in the interior of the main machine, the first end of the cover is rotatably connected to the main machine, the second end of the cover is provided with a pressure roller, the first end and the second end of the cover are opposite ends of the cover, when the cover is closed to the main machine, the first clamping portion 51 and the second clamping portion 52 can be clamped with the pressure roller to keep the cover and the main machine in the closed state, and the first clamping portion 51 and the second clamping portion 52 can be disengaged from the pressure roller by pulling the clamping handle assembly 50, so that the cover can be opened.

[0055] Therefore, the first clamping portion 51 is opposite to and spaced apart from the first side plate 11, and the second clamping portion 52 is opposite to and spaced apart from the second side plate 12, which can prevent friction between the clamping handle assembly 50 and the core support 10 during rotation, so that the user can easily open or close the printer 100.

[0056] In some embodiments, the distance between the first hook portion 51 and the first side plate 11 along the width direction of the printer 100 is d1. If d1 is greater than 1 mm, the gap between the first hook portion 51 and the first side plate 11 is too large, which increases the volume of the printer 100. If d1 is less than 0.3 mm, the gap between the first hook portion 51 and the first side plate 11 is too small, which causes the first hook portion 51 to rub against the first side plate 11 during rotation, thereby wearing the first side plate 11. Therefore, d1 satisfies 1 mm≥d1≥0.3 mm, which ensures that the first hook portion 51 does not rub against the first side plate 11 during rotation and does not increase the volume of the printer 100.

[0057] In some embodiments, the distance between the second hook portion 52 and the second side plate 12 along the width direction of the printer 100 is d2. If d2 satisfies 1 mm≥d2≥0.3 mm, the second hook portion 52 does not rub against the second side plate 12 during rotation and does not increase the volume of the printer 100.

[0058] Please refer to Figure 2 and Figure 3 In some embodiments, the hook handle assembly 50 further includes a handle portion 53 connected to one of the first hook portion 51 and the second hook portion 52. The handle portion 53 drives both the first hook portion 51 and the second hook portion 52 to move, so that both the first hook portion 51 and the second hook portion 52 are engaged with or disengaged from the pressure roller of the printer 100.

[0059] In this embodiment, the handle portion 53 is connected to the end of the first hook portion 51 away from the back plate 20, and the handle portion 53 extends away from the back plate 20, so that the handle portion 53 has a long enough distance from the back plate 20. When the handle portion 53 is manually actuated to drive both the first hook portion 51 and the second hook portion 52 to move, the force arm of the force applied to the handle portion 53 is increased, so that the handle portion 53 can be easily actuated. In other embodiments, the handle portion 53 can be connected to the end of the second hook portion 52 away from the back plate 20.

[0060] When the printer 100 is to be closed, the cover body is rotated toward the main machine, so that the pressure roller on the cover body is engaged with the first hook portion 51 and the second hook portion 52, thereby fixing the cover body to the main machine. When the printer 100 is to be opened, the handle portion 53 is manually actuated to drive the first hook portion 51 and the second hook portion 52 to move relative to the pressure roller, so that the first hook portion 51 and the second hook portion 52 are disengaged from the pressure roller on the cover body, and the cover body can be rotated away from the main machine to open the printer 100.

[0061] Please refer to Figure 3In some embodiments, the handle portion 53 comprises a first plate body 531 connected to one of the first hook portion 51 and the second hook portion 52, and a second plate body 532 connected to the other of the first hook portion 51 and the second hook portion 52, the first plate body 531 and the second plate body 532 are arranged at an angle, and the second plate body 532 extends away from the other of the first hook portion 51 and the second hook portion 52.

[0062] In the present embodiment, the first plate body 531 is connected to the first hook portion 51 away from the back plate 20, and the first plate body 531 can extend away from the back plate 20, thereby extending the distance between the handle portion 53 and the back plate 20, the second plate body 532 is arranged at an angle with the first plate body 531, and the second plate body 532 can extend away from the second hook portion 52, so that the second plate body 532 does not extend between the first hook portion 51 and the second hook portion 52, which can prevent the second plate body 532 from interfering with other components inside the printer 100, and also facilitates the user to move the second plate body 532 with the hand, and the first plate body 531 and the second plate body 532 arranged at an angle can increase the structural strength of the handle portion 53, and facilitate the user to move the handle portion 53.

[0063] In other embodiments, the first plate body 531 can be connected to the second hook portion 52 away from the back plate 20, and the second plate body 532 extends away from the first hook portion 51, which can also increase the structural strength of the handle portion 53 and facilitate the user to move the handle portion 53.

[0064] In some embodiments, the handle portion 53 comprises a connection end and a free end arranged opposite to each other, the connection end is connected to one of the first hook portion 51 and the second hook portion 52, and the distance between the connection end and the free end is h, which satisfies: 50mm≥h≥20mm.

[0065] Optionally, the handle portion 53 is connected to the first hook portion 51, and the end of the handle portion 53 connected to the first hook portion 51 is the connection end, and the free end of the handle portion 53 extends away from the back plate 20, when the user moves the handle portion 53, the user can hold the free end of the handle portion 53 to move the first hook portion 51 and the second hook portion 52.

[0066] When the distance h between the connecting end and the free end is less than 20 mm, the force arm between the force applied to the free end and the rotating connecting position on the back plate 20 is too small, which makes it inconvenient to drive the back plate 20 to rotate. When the distance h between the connecting end and the free end is greater than 50 mm, the length of the handle part 53 is too long, which increases the volume of the printer 100. Therefore, when 50 mm≥h≥20 mm, the force arm of the force applied to the free end is not too small, the back plate 20 can be conveniently driven to rotate, and the volume of the printer 100 is not increased.

[0067] Please refer to Figure 5 In some embodiments, the core support 10 comprises a rear side plate 13 located on the side of the back plate 20 away from the elastic member 40, and the rear side plate 13 is used to abut against the back plate 20 to make the elastic member 40 in a compressed state.

[0068] Optionally, the rear side plate 13 can be located between the first side plate 11 and the second side plate 12, and the rear side plate 13 is located on the side of the back plate 20 away from the elastic member 40, and the rear side plate 13 abuts against the back plate 20 so that the elastic member 40 located between the face plate 30 and the back plate 20 is in a compressed state, thereby the elastic member 40 can stably provide the face plate 30 with elastic force, and the elastic member 40 can provide the face plate 30 with continuous pre-tightening force to drive the heating print head 31 to uniformly contact the carbon ribbon, thereby facilitating continuous and stable printing.

[0069] Please refer to Figure 5 In some embodiments, the size of the rear side plate 13 along the width direction of the printer 100 is less than the size of the back plate 20 along the width direction of the printer 100.

[0070] It can be understood that, since the first side plate 11 and the second side plate 12 are spaced apart along the width direction of the printer 100, and the back plate 20 is arranged between the first side plate 11 and the second side plate 12, the size of the first side plate 11 and the second side plate 12 along the width direction of the printer 100 must be greater than the size of the back plate 20 along the width direction of the printer 100. Since the size of the rear side plate 13 along the width direction of the printer 100 is less than the size of the back plate 20 along the width direction of the printer 100, the rear side plate 13 only occupies a part of the space between the first side plate 11 and the second side plate 12, so that the back plate 20 can be conveniently installed between the first side plate 11 and the second side plate 12 from the other part between the first side plate 11 and the second side plate 12, and the back plate 20 can also be conveniently detached from the first side plate 11 and the second side plate 12. In addition, the smaller size of the rear side plate 13 can also save costs.

[0071] Please refer to Figure 3 and Figure 5In some embodiments, the back plate 20 is rotationally connected with the core support 10, the back plate 20 comprises a first side edge 21 and a second side edge 22 which are oppositely arranged along the width direction of the printer 100, the hook handle assembly 50 comprises a handle portion 53 which is integrally formed with the back plate 20, and the handle portion 53 drives the back plate 20 to rotate, wherein the handle portion 53 is arranged close to one of the first side edge 21 and the second side edge 22, and the back plate 13 is arranged close to the other one of the first side edge 21 and the second side edge 22.

[0072] In the embodiment, a plurality of elastic members 40 are arranged between the back plate 20 and the face plate 30, and the plurality of elastic members 40 can be arranged at intervals along the width direction of the printer 100, or in other words, a part of the plurality of elastic members 40 are arranged close to the first side edge 21 of the back plate 20, another part of the plurality of elastic members 40 are arranged close to the second side edge 22 of the back plate 20, and the remaining part of the plurality of elastic members 40 are arranged between the first side edge 21 and the second side edge 22.

[0073] It should be noted that if the handle portion 53 and the back plate 13 are both arranged close to the first side edge 21, when the handle portion 53 drives the back plate 20 to rotate, the elastic members 40 arranged close to the first side edge 21 of the back plate 20 will be compressed, while the elastic members 40 arranged close to the second side edge 22 of the back plate 20 will drive the second side edge 22 of the back plate 20 to be warped away from the face plate 30, so that the compression of the plurality of elastic members 40 between the back plate 20 and the face plate 30 is not synchronized, and the face plate 30 cannot be provided with a continuous and stable pre-tightening force; if the handle portion 53 and the back plate 13 are both arranged close to the second side edge 22, when the handle portion 53 drives the back plate 20 to rotate, similarly, the elastic members 40 arranged close to the second side edge 22 will be compressed, while the elastic members 40 arranged close to the first side edge 21 will drive the first side edge 21 to be warped away from the face plate 30, so that the compression of the plurality of elastic members 40 is not synchronized, and the face plate 30 cannot be provided with a continuous and stable pre-tightening force.

[0074] Taking the case that the handle portion 53 is arranged close to the first side edge 21 and the back plate 13 is arranged close to the second side edge 22 as an example, when the handle portion 53 is actuated to compress the elastic members 40 arranged close to the first side edge 21, the back plate 13 can abut against the second side edge 22 of the back plate 20, so as to prevent the second side edge 22 from being warped away from the face plate 30, and thus the compression of the plurality of elastic members 40 is synchronized, and the face plate 30 can be provided with a continuous and stable pre-tightening force.

[0075] Similarly, when the handle portion 53 is arranged close to the second side edge 22 and the rear side plate 13 is arranged close to the first side edge 21, the compression of the plurality of elastic members 40 can be synchronized, thereby providing the panel 30 with a continuous and stable pre-tightening force, as long as the handle portion 53 and the rear side plate 13 are respectively located on opposite sides of the back plate 20 along the width direction of the printer 100.

[0076] Referring to Figure 3 and Figures 6 to 10 In some embodiments, the back plate 20 is provided with a first mounting hole 23, the core support 10 is provided with a second mounting hole 14 and a third mounting hole 15, the first mounting hole 23 is located between the second mounting hole 14 and the third mounting hole 15, and the printer 100 further comprises a rotating shaft 60, which is sequentially arranged in the second mounting hole 14, the first mounting hole 23 and the third mounting hole 15, so that the back plate 20 and the core support 10 are rotationally connected.

[0077] In the embodiment, the back plate 20 is provided with a first mounting hole 23 on each of the opposite sides along the width direction of the printer 100, and the two first mounting holes 23 are arranged in the width direction of the printer 100. The core support 10 is provided with a second mounting hole 14 and a third mounting hole 15 on one side along the width direction of the printer 100, and is also provided with a second mounting hole 14 and a third mounting hole 15 on the other side along the width direction of the printer 100. The two first mounting holes 23 are located between the two second mounting holes 14, and the two third mounting holes 15 are located between the two first mounting holes 23.

[0078] For the convenience of description, the first mounting hole 23, the second mounting hole 14 and the third mounting hole 15 located on the same side can be defined as a group of mounting holes, so that each side along the width direction of the printer 100 has a group of mounting holes, and the second mounting hole 14, the first mounting hole 23 and the third mounting hole 15 in the same group can be sequentially communicated. Two rotating shafts 60 can be arranged in the two groups of mounting holes, i.e. the rotating shaft 60 is sequentially arranged in the second mounting hole 14, the first mounting hole 23 and the third mounting hole 15, so that the opposite sides of the back plate 20 along the width direction of the printer 100 are rotationally connected with the core support 10, and the back plate 20 can be conveniently rotated relative to the core support 10.

[0079] Referring to Figure 7 and Figure 9 In some embodiments, the core support 10 is further provided with a first protrusion 16, which is located on the side of the third mounting hole 15 away from the second mounting hole 14 along the axial direction of the third mounting hole 15. The first protrusion 16 abuts against the rotating shaft 60 to limit the movement of the rotating shaft 60 along the axial direction of the third mounting hole 15.

[0080] It can be understood that the first mounting hole 23 is located between the second mounting hole 14 and the third mounting hole 15, and the second mounting hole 14 is closer to the outer side of the movement support 10 relative to the third mounting hole 15, that is, the second mounting hole 14 is closer to the outer surface of the movement support 10 than the second mounting hole 14. When the rotating shaft 60 is installed, the rotating shaft 60 is sequentially arranged in the second mounting hole 14, the first mounting hole 23 and the third mounting hole 15 from the outer side of the movement support 10, the first protrusion 16 is arranged on the side of the third mounting hole 15 away from the second mounting hole 14, so that the first protrusion 16 is located on the path of the rotating shaft 60 extending out of the third mounting hole 15 in the axial direction of the third mounting hole 15, so that the first protrusion 16 can abut against one end of the rotating shaft 60 extending out of the third mounting hole 15, so as to limit the rotating shaft 60 from continuing to extend out of the third mounting hole 15 in the axial direction of the third mounting hole 15, so as to position the rotating shaft 60 in the third mounting hole 15, and prevent the rotating shaft 60 from being separated from the third mounting hole 15.

[0081] In the embodiment, the first protrusion 16 can prevent the rotating shaft 60 from being separated from the third mounting hole 15 by blocking only a part of the third mounting hole 15, so the dimension of the first protrusion 16 in the direction perpendicular to the axial direction of the rotating shaft 60 can be smaller than the radial dimension of the third mounting hole 15, so as to reduce the space occupied by the first protrusion 16, thereby reducing the volume of the printer 100.

[0082] In other embodiments, the first protrusion 16 can be arranged on the inner side of the third mounting hole 15, so that the first protrusion 16 abuts against the rotating shaft 60 inside the third mounting hole 15 to limit the rotating shaft 60 from extending out of the third mounting hole 15, and the volume of the printer 100 can also be reduced.

[0083] Please refer to Figure 9 and Figure 10 In some embodiments, the distance between the side wall defining the second mounting hole 14 and the side wall defining the third mounting hole 15 in the axial direction of the third mounting hole 15 is a, and the wall thickness of the side wall defining the first mounting hole 23 is b, and a and b satisfy: 3mm≥a-b≥1mm.

[0084] It should be noted that the side wall defining the first mounting hole 23 is part of the hook handle assembly 50, and the side wall defining the second mounting hole 14 and the side wall defining the third mounting hole 15 are part of the movement support 10. In order to arrange the first mounting hole 23 between the second mounting hole 14 and the third mounting hole 15, a needs to be smaller than b. Only in this way, there is enough space between the side wall defining the second mounting hole 14 and the side wall defining the third mounting hole 15 to place the side wall defining the first mounting hole 23, and to ensure that the hook handle assembly 50 can rotate smoothly without friction with the movement support 10.

[0085] However, if a-b>3mm, the distance between the side wall defining the second mounting hole 14 and the side wall defining the third mounting hole 15 is too large, which results in the size of the core support 10 being too large, and thus the overall volume of the printer 100 is too large. If a-b<1mm, the distance between the side wall defining the second mounting hole 14 and the side wall defining the third mounting hole 15 is too small, which results in the hook handle assembly 50 rubbing against the core support 10 when the hook handle assembly 50 rotates. Therefore, when a and b satisfy 3mm≥a-b≥1mm, the hook handle assembly 50 can rotate smoothly, and the volume of the printer 100 is not too large.

[0086] Referring to Figure 7 In some embodiments, the side wall defining the third mounting hole 15 further has an observation port 17, the observation port 17 is in communication with the third mounting hole 15, and the rotating shaft 60 is exposed from the observation port 17. Therefore, when the rotating shaft 60 is installed, the installation of the rotating shaft 60 can be checked from the observation port 17, and if the rotating shaft 60 is offset, it can be adjusted in time, so that the rotating shaft 60 can be installed quickly and accurately.

[0087] Referring to Figure 9 In some embodiments, the printer 100 further comprises a motor assembly 70, the motor assembly 70 is installed on the core support 10, and the motor assembly 70 comprises a second protrusion 71, the second protrusion 71 is located on the side of the second mounting hole 14 away from the third mounting hole 15 along the axial direction of the second mounting hole 14, and the second protrusion 71 abuts against the rotating shaft 60 to limit the movement of the rotating shaft 60 along the axial direction of the second mounting hole 14.

[0088] Optionally, after the rotating shaft 60 is sequentially installed in the second mounting hole 14, the first mounting hole 23, and the third mounting hole 15, one end of the rotating shaft 60 can abut against the first protrusion 16 to limit the rotating shaft 60 from extending out of the third mounting hole 15 along the axial direction of the third mounting hole 15. Then, the motor assembly 70 is installed on one side of the core support 10, so that the second protrusion 71 can abut against the end of the rotating shaft 60 away from the first protrusion 16, and the second protrusion 71 can limit the rotating shaft 60 from extending out of the second mounting hole 14 along the axial direction of the third mounting hole 15. Therefore, the rotating shaft 60 can be fixed in the second mounting hole 14, the first mounting hole 23, and the third mounting hole 15, and no other components are needed to position the rotating shaft 60, so the volume of the printer 100 can be reduced.

[0089] Referring to Figures 8 to 10In some embodiments, the machine core support 10 comprises two second mounting holes 14 and two third mounting holes 15, the two second mounting holes 14 and the two third mounting holes 15 are arranged at intervals along the width direction of the printer 100, and the two third mounting holes 15 are located between the two second mounting holes 14. The printer 100 further comprises a micro switch assembly 80 mounted on the machine core support 10, and along the width direction of the printer 100, the micro switch assembly 80 and the motor assembly 70 are located on opposite sides of the machine core support 10 respectively. The micro switch comprises a third protrusion 81, which abuts against the corresponding rotating shaft 60 to limit the axial movement of the rotating shaft 60 along the second mounting hole 14.

[0090] Optionally, the micro switch assembly 80 can be mounted on the machine core support 10, and the micro switch assembly 80 can be used to detect the opening and closing state of the cover. The micro switch assembly 80 and the motor assembly 70 are located on opposite sides of the machine core support 10 respectively, so that the micro switch assembly 80 can be arranged opposite to one set of mounting holes, the motor assembly 70 is arranged opposite to another set of mounting holes, and the micro switch assembly 80 corresponds to one second mounting hole 14, so that the third protrusion 81 on the micro switch assembly 80 can abut against one rotating shaft 60 to limit one rotating shaft 60 from disengaging from the corresponding second mounting hole 14. The motor assembly 70 corresponds to another second mounting hole 14, so that the second protrusion 71 on the motor assembly 70 can abut against another rotating shaft 60 to limit another rotating shaft 60 from disengaging from the corresponding second mounting hole 14. Thus, through the micro switch assembly 80 and the motor assembly 70, the two rotating shafts 60 can be positioned respectively, without the need to set other components to position the rotating shafts 60, which can reduce the volume of the printer 100.

[0091] In some embodiments, the third protrusion 81 is formed by welding on the micro switch assembly 80, that is, a third protrusion 81 is directly formed on the micro switch assembly 80 by soldering. This operation is simple and convenient, and the third protrusion 81 can be quickly formed, reducing the production difficulty.
