Abstract
Description
Technical Field
[0001] The utility model relates to the field of printing equipment, in particular to a switch board for a printer and a printer. Background Art
[0002] Printer mechanisms typically feature a switch plate and a print head, with multiple compression springs positioned between them. The springs provide the elastic force that ensures effective contact between the print head and the paper feed roller, ensuring print quality. The structural strength of the switch plate directly impacts the uniformity of the spring force applied to the print head. Specifically, if the switch plate bends due to insufficient structural strength, the spring force applied to the print head by each compression spring will be unevenly distributed. This, in turn, can lead to variations in the tightness of contact between the print head and the paper feed roller at different locations, ultimately impacting print quality.
[0003] To enhance the structural strength of the switchboard, the prior art typically employs a reinforcement structure on the back of the switchboard, for example, by fixing a reinforcement rod to the back of the switchboard. This design does improve the switchboard's bending resistance to a certain extent through the reinforcement rod, but it also has the following drawbacks: Firstly, it requires the purchase of additional reinforcement rods and screws to secure them, which undoubtedly increases production costs; secondly, the need to install the reinforcement rod during assembly not only increases the number of steps, but also prolongs the overall assembly time and reduces production efficiency.
[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0011] The connecting portion is connected to the switch board body and is used to connect to the mounting carrier;
[0012] The reinforcing portion includes a first bending section and a second bending section. The first bending section is integrally formed with the long side edge of the switch board body and bends and extends toward the front direction of the switch board body. The second bending section is integrally formed with the end of the extension direction of the first bending section and bends and extends toward the back direction of the switch board body.
[0013] In some embodiments, at least two positioning protrusions for sleeve-mounting compression springs are integrally connected to the front surface of the switch board body, and the positioning protrusions are spaced apart along the length direction of the switch board body.
[0014] In some embodiments, the switch plate body is provided with a guide hole penetrating along a thickness direction, and the guide hole is used to cooperate with a guide post of the print head.
[0015] In some embodiments, a groove is provided on the back side of the switch board body, and a bottom of the groove protrudes from the back side of the switch board body.
[0016] In some embodiments, the groove is strip-shaped, and its length direction is the same as that of the switch plate body.
[0017] In some embodiments, the groove is located between adjacent guide holes, or between the positioning protrusion and the guide hole.
[0018] In some embodiments, the end of the first bending section in the extension direction protrudes from the front surface of the switch board body and forms a gap with the print head, and the gap is used to limit the movement stroke of the print head toward the print board body.
[0019] The utility model also provides a switch board for a printer, comprising the switch board for a printer.
[0020] (3) Beneficial effects
[0021] Compared with the prior art, the switch board for a printer and the printer provided by the present invention have the following beneficial effects:
[0022] This printer switch board is securely connected to the mounting carrier via a connecting portion. A compression spring can be positioned on the front of the switch board body to push the print head, thereby fulfilling the switch board's basic function. Furthermore, the switch board's structural strength is enhanced by a reinforcement. Specifically, the first and second bending sections of the reinforcement extend toward the front and back of the switch board body, respectively. This design effectively resists bending toward the front or back when subjected to force, thereby enhancing its bending resistance. This improvement ensures the flatness of the switch board body, ensuring that the compression spring applies more uniform pressure to all parts of the print head, thereby improving the final printing effect.
[0023] More importantly, compared to traditional switch plates with reinforcement rods, the switch plate of this utility model does not require additional complex reinforcement components or tedious additional installation operations. This feature not only reduces production costs but also makes the installation process more convenient and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0031] To improve the structural strength of the switch plate, existing printers typically add a reinforcement structure to the back of the switch plate, such as fixing a reinforcement rod on the back of the switch plate. Although this design can improve the bending resistance of the switch plate through the reinforcement rod, it also has the following defects and shortcomings: First, the need for additional reinforcement rods and screws to fix the reinforcement rods increases production costs; second, the need to install additional reinforcement rods during assembly increases installation operations and time.
[0032] In order to solve the above technical problems, this embodiment provides a switch board for a printer, please refer to Figures 1 to 5 As shown, Figure 1 is a schematic diagram of the printer mechanism in the embodiment, Figure 2 for Figure 1 The cross-sectional view of section A in the figure is as follows: Figure 3 for Figure 1 The cross-sectional view of section B, Figure 4 This is a perspective view of the front side of the switch plate for the printer in the embodiment. Figure 5This is a perspective view of the back side of the switch plate for the printer in the embodiment.
[0033] A switch board for a printer in this embodiment includes a switch board body 1 , a connecting portion 2 and a reinforcing portion 3 .
[0034] like Figure 4 and Figure 5 As shown, the switch board body 1 is provided with a front side 11 and a back side 12 , wherein the front side 11 is the side facing the print head 4 and is used for mounting the compression spring 5 .
[0035] like Figure 1 and Figure 2 As shown, the connecting portion 2 is connected to the switch board body 1 and is used to connect the mounting carrier 6. The mounting carrier 6 can be the outer shell or internal component of the printer movement. The connection method of the connecting portion 2 and the mounting carrier 6 can adopt the existing connection method, such as connecting through a shaft.
[0036] like Figure 3 and Figure 4 As shown, the reinforcing portion 3 includes a first bending section 31 and a second bending section 32. The first bending section 31 is integrally formed with the long side edge of the switch board body 1 and bends and extends toward the front side 11 of the switch board body 1. The second bending section 32 is integrally formed with the end of the extension direction of the first bending section 31 and bends and extends toward the back side 12 of the switch board body 1.
[0037] The printer switch board of the above technical solution is connected to the mounting carrier 6 via the connecting portion 2. A compression spring 5 can be provided on the front face 11 of the switch board body 1 to push the print head 4, thereby achieving the basic function of the switch board. At the same time, the structural strength of the printer switch board is enhanced by the reinforcement portion 3. Specifically, the first bending section 31 and the second bending section 32 of the reinforcement portion 3 extend toward the front face 11 and the back face 12 of the switch board body 1, respectively. This makes it less likely that the switch board body 1 will bend toward the front face 11 or back face 12 when subjected to force. This improves the bending resistance of the switch board body 1, ensures the flatness of the switch board body 1, and further improves the uniformity of the compression spring 5's action on various parts of the print head 4 and the final printing effect. Last but not least, compared to switch boards with reinforcement rods, the switch board of the above technical solution does not require additional structural reinforcement components or additional installation operations, resulting in lower production costs and more convenient installation.
[0038] For example, see Figure 1 As shown, the switch board body 1 has two long sides, and reinforcement parts 3 are respectively provided on the two long sides, and the two reinforcement parts 3 are symmetrically arranged.
[0039] In order to further enhance the bending resistance of the switch plate body 1 and realize the guiding function of the compression spring 5, refer to Figure 3 and Figure 4As shown, the front face 11 of the switch panel body 1 is integrally connected with at least two positioning protrusions 13 for sleeved compression springs 5. The positioning protrusions 13 are arranged at intervals along the length direction of the switch panel body 1. The positioning protrusions 13 can guide the compression spring 5 by sleeved compression spring 5 so that the compression spring 5 can be extended and retracted along the positioning protrusions 13. At the same time, by being integrally connected with the switch panel body 1, the structural strength of the switch panel body 1 is improved.
[0040] Exemplarily, the positioning protrusion 13 is integrally connected to the front surface 11 of the switch board body 1 by integral molding or welding.
[0041] For example, see Figure 4 As shown, two positioning protrusions 13 are provided and are respectively located at two ends of the switch board body 1 .
[0042] Further, see Figure 3 and Figure 4 As shown, in order to guide the movement direction of the print head 4 and improve the bending resistance of the switch board body 1, the switch board body 1 is provided with a guide hole 14 running through the thickness direction. The guide hole 14 is used to cooperate with the guide column of the print head 4, that is, the guide column moves through the guide hole 14.
[0043] Illustratively, the guide holes 14 are located between the positioning protrusions 13 , and the distances between adjacent guide holes 14 and between adjacent guide holes 14 and the positioning protrusions 13 are the same.
[0044] In order to further enhance the bending resistance of the switch panel body 1, refer to Figure 4 and Figure 5 As shown, a groove 15 is provided on the back side 12 of the switch board body 1, and the bottom of the groove 15 protrudes from the back side 12 of the switch board body 1, so that the groove 15 forms a convex and a concave structure on the front side 11 and the back side 12 of the switch board body 1, respectively, which can effectively disperse and reduce the bending stress of the switch board body 1.
[0045] For example, see Figure 4 As shown, the groove 15 is strip-shaped, and its length direction is the same as that of the switch board body 1 .
[0046] For example, see Figure 4 As shown, there are more than two grooves 15 , which are arranged at intervals. The grooves 15 are located between adjacent guide holes 14 , or between the positioning protrusions 13 and the guide holes 14 .
[0047] In one embodiment of the first bending section, see Figure 5 As shown, the end of the first bending section 31 in the extension direction protrudes from the front surface 11 of the switch board body 1 and forms a gap with the print head 4, which is used to limit the movement of the print head 4 toward the print board body.
[0048] This embodiment discloses a switch board for a printer. Figure 1 and Figure 2 As shown, the switch board includes the aforementioned printer. The connection and coordination between the switch board and other printer components can be achieved using existing techniques and will not be further elaborated here. By utilizing the aforementioned printer switch board, the printer of this embodiment ensures that the pressure applied by the compression spring 5 to the print head 4 is more uniform, thereby improving the final printing effect. Furthermore, no additional structural reinforcement components or installation steps are required, resulting in lower production costs and more convenient installation.
[0049] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
