Description

Technical Field

[0001] The utility model relates to the technical field of printer waterproof covers, in particular to a fixing structure of a printer waterproof cover. Background Art

[0002] In the current business environment, the application scope of printers has far exceeded the traditional shopping mall and supermarket POS systems, and has successfully penetrated into catering services, lottery sales and other fields, significantly improving service efficiency and accuracy. Taking the catering industry as an example, the front-end order information can be instantly transmitted to the printer equipped in the kitchen through the network, realizing the rapid printing of menus and directly guiding the kitchen to prepare dishes according to the order. This process greatly improves the order speed and order accuracy. However, it is worth noting that the special working environment of the kitchen is full of oil smoke and water vapor, which makes the printer, especially its paper outlet, extremely susceptible to oil stains and water droplets, resulting in frequent equipment failures and affecting normal operations.

[0003] In response to the above challenges, there have been technical innovations such as China Publication No. CN101746163A, which discloses a printer design with an integrated waterproof and dustproof cover. This design uses a cleverly placed protective cover to fully cover the printer's paper outlet and the gap between the shell, effectively blocking the intrusion of moisture and dust, significantly enhancing the printer's ability to operate stably under harsh conditions and broadening its application environment. The protective cover in this design is connected to the printer body in an articulated manner, achieving seamless integration with the body, which is both easy to operate and saves space, further optimizing the user experience.

[0004] Nevertheless, existing technical solutions, including the above-mentioned designs, still have certain limitations. In particular, in actual operation, if the protective cover of these printers does not exceed 90° during the opening process, they tend to close automatically, which not only interferes with the user's normal operation process, but may also cause inconvenience or even misoperation in a busy working environment, which constitutes an unnecessary obstacle to work efficiency. Therefore, how to improve the opening and closing mechanism of the printer cover while maintaining the existing protective performance to achieve a smoother and non-interference operation experience has become a technical problem that needs to be solved urgently.

[0005] In view of this, the inventor specially designed a printer waterproof cover fixing structure, and this case was thus generated. Utility Model Content

[0006] In order to solve the above problems, the technical solution of the utility model is as follows:

[0007] A printer waterproof cover fixing structure, comprising:

[0008] A housing having a paper outlet;

[0009] A protective cover, one end of which forms an opening covering the paper outlet and two sides of which form side walls, and the inner sides of the two side walls and the side away from the opening form hinge points hinged to the side walls of the shell on both sides;

[0010] The limiting point is convexly arranged on the inner sides of the two side walls and is located on the side of the hinge away from the opening. When overlapping with the side wall of the shell, it is used to generate a limit to limit the flipping angle of the protective cover.

[0011] Preferably, the shell is located at an edge of a hinged side with the protective cover to form an escape zone so that the protective cover is in a suspended position in a non-contact state when the protective cover is covered on the paper outlet of the shell.

[0012] Preferably, the shell is located at an edge on the hinged side of the protective cover to form an inclined transition surface, and the outer side of the transition surface forms the avoidance area.

[0013] Preferably, the distance between the limiting point and the side wall surface is greater than the distance between the inner surface of the side wall and the closest side wall of the shell.

[0014] Preferably, the side walls on both sides of the shell are provided with at least one recessed groove which is recessed inwards and can accommodate the limit point.

[0015] Preferably, there are a plurality of the give-way grooves and adjacent give-way grooves are distributed in parallel.

[0016] Preferably, the plurality of said clearance grooves are arranged obliquely along the top of the shell toward the rear side wall of the shell.

[0017] Preferably, the distance between the two sides of the clearance groove is greater than the maximum width of the limiting point.

[0018] Preferably, the cross section of the relief groove is an arc-shaped depression.

[0019] Preferably, both side walls of the shell are symmetrically provided with inwardly recessed hinge grooves, and the hinge point is limitedly engaged with the hinge groove to achieve hinge connection.

[0020] The beneficial effects of the utility model are as follows:

[0021] The utility model cleverly realizes flexible control of the opening and closing of the protective cover by setting limit points and the side walls of the shell, ensuring that the user can freely adjust the angle of the protective cover according to actual needs, and effectively prevents the protective cover from accidentally rebounding and closing when it is not fully unfolded (for example, less than 90°), thereby greatly reducing interference factors and potential risks of misoperation during operation, greatly improving the smoothness of operation and overall work efficiency, and bringing users a more convenient and efficient user experience.

[0022] The utility model ingeniously realizes the flexible control of the opening and closing of the protective cover through the interaction mechanism of the carefully designed limit point and the side wall of the shell, ensuring that the user can freely adjust the angle of the protective cover according to actual needs, and effectively prevents the protective cover from accidentally rebounding and closing when it is not fully unfolded (for example, less than 90 degrees), thereby greatly reducing the interference factors and potential risks of misoperation during operation, greatly improving the smoothness of operation and overall work efficiency, and bringing users a more convenient and efficient use experience

[0023] In addition, the limit point is precisely matched with the paving groove on the side wall of the shell. The paving groove provides space for the limit point, and the side wall of the paving groove is used to limit the flipping of the protective cover, thereby avoiding the limit point and the side wall of the shell being in an extrusion state all the time, thereby enhancing the stability of the overall structure and ensuring reliability and durability in long-term use.

[0024] In addition, the avoidance area at the edge of the shell ensures that the limiting point of the protective cover is suspended when the protective cover is closed on the upper end of the shell, avoiding the limiting point and the side wall of the shell being always in an extruded limiting state, thereby extending the service life of the entire limiting structure.

[0025] In addition, through the design of the hinge groove, the connection between the protective cover and the shell is more stable and easy to disassemble, which is convenient for users to perform regular cleaning and maintenance, ensuring the continuous and efficient operation of the printer in harsh environments.

[0026] To sum up, the printer waterproof cover fixing structure provided by the utility model effectively solves the problem of inconvenient operation of the protective cover in the prior art through sophisticated mechanical design, while maintaining good waterproof and dustproof performance, providing an innovative solution for the stable application of the printer in special working environments.

[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0041] See also Figures 1 to 9 , is a printer waterproof cover fixing structure as the best embodiment of the utility model, comprising:

[0042] The housing 10 includes a lower cover 11 and an upper cover 12. The upper cover 12 is buckled on one side edge of the top of the lower cover 11, and the upper end surface of the upper cover 12 has a paper outlet 13.

[0043] The protective cover 20 has an opening 23 at one end thereof that covers the paper outlet 13 and side walls 21 at both sides thereof. The inner sides of the side walls 21 and the side located away from the opening 23 form hinge points 22 that are hinged to the side walls of the housing 10. In this embodiment, the protective cover 20 is rotatably arranged at a position of the upper cover 12 close to the edge of the housing 10. When the protective cover 20 is closed, it can cover various gaps formed between the upper cover 12 and the lower cover 11 due to the splicing, thereby achieving waterproof and dustproof, and cooperates with the paper outlet 13 through the opening 23 to avoid restricting the normal paper output of the printer;

[0044] In order to enhance the protective effect of the paper outlet 13, the protective cover 20 is provided with a raised support portion 24 at the position of the opening 23 thereof, thereby lifting the opening 23 to a position farther away from the paper outlet 13, and forming a storage area (not shown in the figure) for temporarily accommodating the printing paper between the paper outlet 13 and the opening 23, so as to prevent the printing paper from being directly discharged from the opening 23 and being contaminated by common external pollution sources such as water, dust or oil stains.

[0045] The limiting point 30 is protrudingly disposed on the inner side of the two side walls 21 and is located on the side of the hinge 22 away from the opening 23 . When overlapping with the side wall of the housing 10 , it is used to generate a limit to limit the flip angle of the protective cover 20 .

[0046] In this embodiment, Figure 2 , 3 As shown, the two side walls at the upper end of the lower cover 11 are symmetrically provided with inwardly recessed hinge grooves 14, and the hinge point 22 is limitedly engaged with the hinge groove 14 to achieve hinge connection, and the hinge point 22 is columnar, and the hinge groove 14 is a columnar groove engaged with the hinge point 22, thereby facilitating the rotational connection between the protective cover and the lower cover 11, so that the protective cover can stably cover the upper end of the paper outlet 13.

[0047] Preferably, Figure 2 , 4 As shown in Figures 5 and 6, the edge of the shell 10 is located at the hinged side with the protective cover 20 to form an escape zone 16 so that the limit point 30 is in a suspended position in a non-contact state when the protective cover 20 is covered on the paper outlet 13 of the shell 10. Specifically, the lower cover 11 of the shell 10 is located at the edge of the hinged side with the protective cover 20 to form an inclined transition surface 15, and the escape zone 16 is formed outside the transition surface 15. In this embodiment, the hinge groove 14 is arranged on the side wall of the lower cover 11 and is located close to the escape zone 16, so that the protective cover and the shell 10 can be easily rotated. The escape zone 16 at the edge of the shell 10 makes the limit point 30 of the protective cover 20 in a suspended state when it is covered on the upper end of the shell 10, avoiding the limit point 30 and the side wall of the shell 10 from always being in an extruded limit state, thereby fully extending the service life of the limit structure as a whole.

[0048] Preferably, Figure 3 , 6As shown in Figures 7 and 8, the distance D1 between the limit point 30 and the surface of the side wall 21 is greater than the distance D2 between the inner surface of the side wall 21 and the nearest side wall of the shell 10. In this embodiment, the shell 10, the protective cover and the limit point 30 are all made of deformable materials such as plastic. The limit point 30 is columnar, and the height of the limit point 30 is set to be greater than the distance between the side wall 21 and the side wall of the shell 10, so that when the limit point 30 rotates with the protective cover to the area overlapping with the side wall of the shell 10, it can be compressed and deformed to squeeze the side wall of the shell 10, and then the friction force generated by the extrusion can limit the rotation position of the protective cover, thereby realizing the fixed angle adjustment of the protective cover.

[0049] Preferably, Figure 2 , 4 As shown in FIGS. 5 and 5 , at least one recessed groove 40 is provided on both side walls of the shell body 10, which is recessed inward and can accommodate the limit point 30. Specifically, in the present embodiment, a plurality of recessed grooves 40 are provided and adjacent recessed grooves 40 are distributed in parallel. A plurality of recessed grooves 40 are located along the top of the shell body 10 at the edge of the upper cover 12 and their bottoms are inclined toward the rear side wall of the lower cover 11. The hinge groove 14 is provided in one of the recessed grooves 40. Thus, the limit point 30 is precisely matched with the recessed groove 40 on the side wall of the shell body 10. The recessed groove 40 provides a recessed area for the limit point 30. At the same time, the side wall of the recessed groove 40 is used to limit the flipping of the protective cover 20, thereby avoiding the limit point 30 and the side wall of the shell body 10 from being always in an extruded state, thereby enhancing the stability of the overall structure and ensuring the reliability and durability of long-term use.

[0050] Preferably, Figure 8 , 9 As shown, the spacing between the two sides of the clearance groove 40 is greater than the maximum width of the limit point 30. In this embodiment, the cross-section of the clearance groove 40 is an arc-shaped depression, so that the limit point 30 moves in a limited manner between the two side edges of the clearance groove 40. The two side edges of the limit groove simultaneously limit the limit point 30, so that the protective cover can rotate in a small range in the restricted area between the two side edges of the limit groove. At this time, the clearance groove 40 can not only provide clearance for the limit point 30, but also limit the rotation of the protective cover, thereby achieving a stable limitation on the rotation angle of the protective cover.

[0051] In particular, if Figure 1 , 2 As shown in Figures 4 and 5, the edge of the upper cover 12 is provided with an arc-shaped guide surface 121 which is connected with the lower cover 11, and the arc-shaped guide surface 121 is provided with an extension groove 122 which is opposite to the plurality of make way grooves 40 and is formed as one piece with the make way grooves 40, so that the make way grooves 40 form a beautification structure on the shell 10, thereby increasing the overall beauty of the shell 10.

[0052] The beneficial effects of the utility model are as follows:

[0053] The utility model cleverly realizes the flexible control of the opening and closing of the protective cover 20 by setting the limit point 30 and the side wall of the shell 10 to ensure that the user can freely adjust the angle of the protective cover 20 according to actual needs, and effectively prevents the protective cover 20 from accidentally rebounding and closing when it is not fully unfolded (for example, less than 90°), thereby greatly reducing interference factors and potential risks of misoperation during operation, greatly improving the smoothness of operation and overall work efficiency, and bringing users a more convenient and efficient use experience.

[0055] In addition, through the design of the hinge groove 14, the connection between the protective cover 20 and the housing 10 is more stable and easy to disassemble, which is convenient for users to perform regular cleaning and maintenance, ensuring the continuous and efficient operation of the printer in harsh environments.

[0056] In summary, the printer waterproof cover fixing structure provided by the utility model effectively solves the problem of inconvenient operation of the protective cover 20 in the prior art through sophisticated mechanical design, while maintaining good waterproof and dustproof performance, providing an innovative solution for the stable application of the printer in special working environments.

[0057] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
