Description

Technical Field

[0001] The present invention relates to a printer internal line fastening device and a printer comprising the printer internal line fastening device. Background Art

[0002] Printers are common devices in our daily lives, housing numerous cables and flexible circuit boards. Currently, these cables and flexible circuit boards are often attached to the printer casing using fiber tape or other adhesive tape. During actual use or assembly, this method can lead to loosening of the cables and flexible circuit boards, as the adhesive tends to lose viscosity over time. This can severely impact the printer's performance. Summary of the Invention

[0014] The present invention will be described below with reference to the accompanying drawings.

[0015] Figure 1 A schematic diagram showing the connection between a printer internal line fastening device and a printer according to an embodiment of the present invention is shown.

[0016] Figure 2 for Figure 1 A partially enlarged schematic diagram of the connection schematic shown.

[0017] Figure 3 for Figure 1 The schematic diagram of the structure of the internal line fastening device of the printer is shown.

[0018] In this application, all drawings are schematic drawings, which are only used to illustrate the principles of the present invention and are not drawn to scale. DETAILED DESCRIPTION

[0019] The present invention will be described below with reference to the accompanying drawings.

[0020] Figure 1 FIG. 1 shows a schematic diagram of the connection between the printer internal line fastening device 100 and the printer 10 according to an embodiment of the present invention. Figure 1 As shown, the printer internal line fastening device 100 includes a first fastener 20 and a second fastener 30 disposed in the printer 10 and capable of respectively fixing the flexible circuit board 26 and the flat cable 36 inside the printer.

[0021] Figure 2 for Figure 1 The diagram is a partial enlarged diagram of the connection diagram shown in FIG. Figure 2 As shown, the first fastener 20 is configured in a generally "n" shape, comprising two first vertical walls 22 arranged in a vertical direction and a first horizontal wall 24 disposed at the upper ends of the first vertical walls 22. A first gap 25 is thereby formed between the two first vertical walls 22 of the first fastener 20. Similarly, the second fastener 30 comprises two second vertical walls 32 arranged in a vertical direction and a second horizontal wall 34 disposed at the upper ends of the second vertical walls 32. A second gap 35 is formed between the two second vertical walls 32 of the second fastener 30.

[0022] It should be noted that the wall bodies constituting the first fastener 20 and the second fastener 30 may also be set to other shapes, such as a curved shape or other shapes that are compatible with the internal space of the printer 10, which is not limited here.

[0023] Therefore, when the flexible circuit board 26 and the cable 36 in the printer 10 pass through the first gap 35 and the second gap 35 respectively, the first gap 35 and the second gap 35 can respectively limit and fix the flexible circuit board 26 and the cable 36.

[0024] Compared to the existing method of fixing the flexible circuit board 26 and the cable 36 in the printer 10 using fiber tape or other adhesive tape, the fastening device 100 of the present invention can make the routing of the flexible circuit board 26 and the cable 36 more regular, thereby avoiding problems such as poor assembly or cable breakage caused by unstable routing during assembly.

[0025] At the same time, the fastening device 100 of the present invention is not easy to loosen, thereby preventing the internal wiring of the printer or the flexible circuit board from being detached from the printer 10 due to the weakening of the viscosity of the fiber tape during use, thereby avoiding poor contact of the circuit and improving the reliability of the printer 10.

[0026] Figure 3 for Figure 1 The schematic diagram of the structure of the internal line fastening device 100 of the printer is shown in FIG. Figure 3 As shown, a plurality of cable grooves 38 are evenly distributed along the vertical direction on the vertical wall 32 of the second fastener 30, each matching the shape of the cable 26. This allows the multiple cable 26 in the printer 10 to be fixed in the cable grooves 38 in a one-to-one correspondence. This arrangement allows the cable grooves 38 to separate the cables, preventing the cables 26 from becoming mixed up and affecting their normal assembly and use.

[0027] like Figure 2As shown, in the present invention, the first fastener 20 is connected to the middle frame 40 in the printer 10. The first fastener 20 can move vertically relative to the middle frame 40 and can rotate relative to the middle frame 40. At the same time, the second fastener 40 is fixedly connected to the first fastener 30, so that the second fastener 40 can rotate synchronously with the first fastener 30.

[0028] Specifically, a groove 42 is provided on the sidewall of the middle frame 40. A first wall 221 of the first vertical wall 22, located near the middle frame 40, is configured to be vertically inserted into the groove 42 and to move vertically within the groove 42, thereby driving the first and second fasteners 30 and 40 to move vertically. Furthermore, the first wall 221 is also capable of rotating within the groove 42, driving the first and second fasteners 30 and 40 to rotate within the printer 10.

[0029] Therefore, during the installation of the flexible circuit boards 26, the operator can first move the first wall 221 upward, causing the first fastener 30 to move upward, until the second wall 222 moves to a position higher than the middle frame 40. The operator then rotates the first wall 221, causing the first fastener 30 to rotate synchronously, until the second wall 222 rotates from a first position opposite the side wall 41 of the middle frame 40 to a second position not opposite the side wall 41 of the middle frame 40. The flexible circuit boards 26 can then be installed, with the multiple installed flexible circuit boards 26 being attached to the side wall 41 of the middle frame 40. It will be readily understood that during the installation of the flexible circuit boards 26, rotating the second wall 222 to the second position prevents the second wall 222 from blocking the outside of the side wall 41, thereby preventing the second wall 222 from obstructing the installation of the flexible circuit boards 26.

[0030] Essentially, the length of the first wall 221 is set to be greater than the length of the second wall 222 away from the middle frame 40. With this arrangement, when the second wall 222 moves to a position higher than the middle frame 40, the first wall 221 can still be inserted into the groove 42, thereby preventing the first wall 221 from detaching from the middle frame 40.

[0031] like Figure 3 As shown, in a preferred embodiment, a first boss 224 is provided on the sidewall at the lower end of the first wall 221. Simultaneously, a second boss (not shown) is provided on the sidewall at the upper end of the groove 42. The first boss 224 can abut against the second boss when the first wall 221 is about to be withdrawn from the groove 42, thereby limiting the first wall 221 from further vertical upward movement and preventing the first wall 221 from detaching from the groove 42.

[0032] like Figure 2As shown, the printer internal line fastening device 100 of the present invention further includes a fixing assembly 50 disposed in the printer 10 , and the fixing assembly 50 can fix the first fastener 20 and the second fastener 30 after the flexible circuit board 26 and the flat cable 36 are installed.

[0033] Specifically, if Figure 2 As shown, the fixing assembly 50 includes a stud 52 fixed to the printer 10, with a screw hole 521 provided on the stud 52, and a horizontal plate 56 fixedly connected to the side of the first fastener 30 away from the middle frame 40, with a through hole 58 provided on the horizontal plate 56. The fixing assembly 50 also includes a screw 59.

[0034] When the horizontal plate 56 rotates with the first fastener 30 to a position vertically above the stud 52, the screw 59 can pass through the through hole 58 and securely connect with the screw hole 521. Thus, after the flexible circuit board 26 and the flat cable 36 are installed, the fixing assembly 50 can secure the first fastener 30 to the stud 52, preventing the first fastener 30 from vibrating or shaking, which could affect the securing of the flexible circuit board 26 and the flat cable 36.

[0035] like Figure 3 As shown, to simplify the structure and reduce the size of the fastening device 100 of the present invention, facilitating its installation in a smaller printer 10, the first fastener 30 and the second fastener 40 are injection-molded into an integral structure. Furthermore, a third gap 39 is provided between the first fastener 30 and the second fastener 40. Similar to the second gap 35, the cable 36 can also pass through the third gap 39, thereby allowing the third gap 39 to also serve as a securing mechanism for the cable 36.

[0036] In a preferred embodiment, the first fastener 30 and the second fastener 40 are made of rubber or plastic materials, which have good wear resistance, small weight and low production cost, and can make the printer lighter and have lower production cost while meeting the fastening requirements.

[0037] The following briefly describes the working process of the printer internal line fastening device 100 according to the present invention.

[0038] During assembly of the printer 10's internal circuitry, the first wall 221 is first moved upward, causing the first fastener 30 to move upward until the second wall 222 is above the middle frame 40. The first wall 221 is then rotated until the second wall 222 moves from a first position opposing the sidewall 41 of the middle frame 40 to a second position opposing the sidewall 41 of the middle frame 40. At this point, the flexible circuit board 26 can be installed, affixing it to the sidewall 41 of the middle frame 40.

[0039] After the flexible circuit board 26 is attached to the middle frame 40, the first wall 221 can be rotated in the opposite direction until the horizontal plate 58 is directly above the stud 52. Multiple cables 36 can then be installed in sequence in different cable ducts 38. Once the cables 36 are installed, the first wall 221 can be moved downward until the horizontal plate 58 abuts the stud 52. Finally, the horizontal plate 58 is secured to the stud 52 with screws 59, completing the circuit assembly process.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and does not constitute any limitation to the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
