[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0040] The shell of the existing linkage printer is relatively thick. At the same time, after the upper and lower shells are opened, the print head and the rubber roller are easily exposed to the outside in a large area, and the dust and pollution prevention capabilities of the printer will be relatively weak.
[0041] To solve the above technical problems, this embodiment provides a linkage printer. Figures 1 to 4 As shown, Figure 1 This is a three-dimensional diagram of the linked printer in the embodiment in the open state. Figure 2 It is a three-dimensional diagram of the internal structure of the linkage printer in the embodiment. Figure 3 This is a schematic diagram of the linked printer in the embodiment when the upper housing is closed. Figure 4 It is a schematic diagram of the linkage printer in the embodiment when the upper shell is opened.
[0042] The linkage printer of this embodiment includes: a lower housing 1 , a rubber roller 2 , a print head assembly 3 and an upper housing 4 .
[0043] The lower housing 1 is provided with a printing paper passage 11 for conveying printing paper. It can be understood that the printing paper passage 11 can guide the printing paper.
[0044] The rubber roller 2 is arranged inside the lower housing 1 and located at one side of the printing paper passage 11, and is used to drive the printing paper to be transported forward.
[0045] The print head assembly 3 includes a rotating bracket 31, a print head 32 and an elastic member 33. The rotating bracket 31 is rotatably connected to the lower housing 1. The elastic member 33 is arranged between the rotating bracket 31 and the lower housing 1. The print head 32 is arranged on the rotating bracket 31. The print head 32 is located inside the lower housing 1 and at the other side of the printing paper passage 11.
[0046] The upper shell 4 is rotatably connected to the lower shell 1 and can be opened and closed relative to the lower shell 1 by rotating. The upper shell 4 includes a push block 41 .
[0047] When the upper shell 4 is closed, Figure 3 As shown, the elastic member 33 pushes the rotating bracket 31 so that the print head 32 abuts against the rubber roller 2. The above-mentioned abutment is not necessarily a direct contact, but means that the printing paper can be printed and transported between the print head 32 and the rubber roller 2 during printing; when the upper shell 4 is opened, as shown in FIG. Figure 4 As shown, the push block 41 pushes the rotating bracket 31 to separate the print head 32 and the rubber roller 2, and the channel of the print head 32 is opened.
[0048] The rubber roller 2 and the print head assembly 3 of the linkage printer of the above technical solution are both arranged on the lower housing 1 and are respectively located on both sides of the printing paper passage 11, so that the thickness of the upper housing 4 can be reduced while the thickness of the lower housing 1 remains unchanged. At the same time, the print head 32 and the rubber roller 2 are located inside the lower housing 1, and are only partially exposed in the print head 32 passage when the upper housing 4 is opened. Compared with the design of the existing printer in which the print head 32 and the rubber roller 2 are separated and a larger area is exposed to the outside, it can effectively reduce the entry of dust and debris and improve the protection performance of the printer. Last but not least, when the upper shell 4 is closed, the elastic member 33 pushes the rotating bracket 31 to make the print head 32 abut against the rubber roller 2, and the printing paper can be printed between the print head 32 and the rubber roller 2; when the upper shell 4 is opened, the push block 41 pushes the rotating bracket 31 to separate the print head 32 and the rubber roller 2, and the print head 32 channel is opened, and the operator can put the printing paper into the print head 32 channel or clean the print head 32 from the print head 32 channel; it can be seen that the closing and opening actions of the upper shell 4 can synchronously realize the abutment and separation of the print head 32 and the rubber roller 2, and the operation is simple.
[0049] In one embodiment of the above-mentioned rotating bracket 31 being rotatably connected to the lower housing 1, see Figure 2 As shown, the print head assembly 3 includes a print shaft 34 connected to the lower shell 1, and the print shaft 34 can be installed in the shaft hole of the lower shell 1. The rotating bracket 31 includes a pair of connecting ears 301, and the connecting ears 301 are provided with connecting holes, and are sleeved on the print shaft 34 through the connecting holes, so that the rotating bracket 31 can rotate around the print shaft 34.
[0050] In one embodiment of the elastic member 33, see Figure 2 and Figure 4 As shown, the elastic member 33 is a torsion spring, which is sleeved on the outside of the printing shaft 34 and located between the connecting ears 301. One end of the torsion spring abuts against the lower shell 1, and the other end abuts against the rotating bracket 31. In this way, the torsion spring can be supported by the lower shell 1 to push the rotating bracket 31 to rotate.
[0051] For example, see Figure 2 and Figure 4As shown, the rotating bracket 31 is provided with a rotating end on each side of the printing shaft 34, the printing head 32 is connected to the first rotating end, and the pushing block 41 faces the second rotating end; when the upper shell 4 is closed, the torsion spring pushes the first rotating end of the rotating bracket 31 to make the printing head 32 rest against the rubber roller 2; when the upper shell 4 is opened, the pushing block 41 pushes the second rotating end of the rotating bracket 31 to separate the printing head 32 and the rubber roller 2.
[0052] For example, see Figure 2 and Figure 3 As shown, a limit portion 302 is provided on the rotating end, and the limit portion 302 is used to contact the lower shell 1 when the upper shell 4 is closed to limit the maximum rotation angle of the rotating bracket 31. The limit portion 302 is integrally formed on the first rotating end and is limited on a protrusion 12 of the lower shell 1 when the upper shell 4 is closed, thereby ensuring that the distance between the print head 32 and the rubber roller 2 will not be less than a preset size.
[0053] In another embodiment of the elastic member 33, the elastic member 33 is a tension spring or a compression spring (not shown) connected between the rotating bracket 31 and the lower shell 1. The tension spring or the compression spring pushes the rotating bracket 31 through deformation, so that the print head 32 abuts against the rubber roller 2 when the upper shell 4 is closed.
[0054] In one embodiment of the above-mentioned upper housing 4 and lower housing 1 being rotatably connected, refer to Figure 1 and Figure 5 As shown, Figure 5 It is a three-dimensional diagram of the connecting part and the push block of the upper shell in the embodiment. The lower shell 1 is provided with a connecting port 13, and the upper shell 4 includes a connecting part 42 extending toward the lower shell 1. The connecting part 42 is rotatably connected to the inner side of the connecting port 13 through a rotating shaft 43. The push block 41 is arranged at the bottom end of the connecting part 42 and passes through the connecting port 13 toward the rotating bracket 31. With such an arrangement, the upper shell 4 can be rotated relative to the lower shell 1 through the rotating shaft 43. During the rotation, the push block 41 can push the rotating bracket 31 to rotate, thereby separating the print head 32 and the rubber roller 2.
[0055] For example, see Figure 1 As shown, a torsion spring is sleeved on the rotating shaft 43, one end of the torsion spring abuts against the upper shell 4, and the other end abuts against the lower shell 1, for providing a force for the upper shell 4 to move from a closed state to an open state.
[0056] For example, see Figure 1 and Figure 2 As shown, the lower shell 1 is provided with a paper bin 14 connected to the printing paper channel 11. The paper bin 14 is used to place printing paper and does not overlap with the rubber roller 2 and the print head assembly 3 in the thickness direction of the lower shell 1, thereby avoiding the overlap of the paper bin 14 and the rubber roller 2 or the print head 32 to increase the thickness of the lower shell 1.
[0057] In order to keep the upper shell 4 and the lower shell 1 in a closed state, refer to Figure 1 , Figure 2 and Figure 6 As shown, Figure 6 It is a three-dimensional diagram of the cooperation between the hook and the wire spring in the embodiment, the upper shell 4 includes a hook 44, the lower shell 1 is provided with a bayonet 15, and a wire spring 16 is provided on the inner side of the bayonet 15; when the upper shell 4 is closed, the hook 44 is located in the bayonet 15 and is buckled with the wire spring 16, wherein the hook portion of the hook 44 is provided with an inclined surface on both sides of the front and rear in the buckling direction, so that the hook 44 can be buckled or disengaged with the wire spring 16 through the inclined surface, and both ends of the wire spring 16 can be fixed to the inside of the lower shell 1 by screws and have a certain elastic deformation ability; compared with the existing buckle structure that plays a fixing role between shells, the cooperation between the hook 44 and the wire spring 16 can omit the button of the traditional buckle structure used for unlocking, so that the product volume is reduced and the appearance is simplified.
[0058] For example, see Figure 2 and Figure 4 As shown, the print head assembly 3 includes a bracket sleeve 35, which is sleeved on the second rotating end of the rotating bracket 31; when the upper shell 4 is opened, the push block 41 pushes the bracket sleeve 35 to rotate the rotating bracket 31, so that the print head 32 and the rubber roller 2 are separated.
[0059] 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 the 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.
