[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0032] like Figure 1 and Figure 2 As shown, the utility model provides a highly efficient sealed waterproof structure of a printer communication interface 200, including a rectangular silicone body 1, the material of which is silicone, which is easily deformed by extrusion to seal the gap between the housing 100 and the communication interface 200. The silicone body 1 is divided into a plurality of sealing unit 2 areas for sealing the communication interface 200, and different sealing unit 2 areas are used to seal different communication interfaces 200. The sealing unit 2 is provided with a receiving space 4 for the card-connected communication interface 200, and the silicone material around the receiving space 4 is tightly wrapped around the communication interface 200 by interference fit. In addition, the silicone body 1 is extruded during assembly to complete the sealing between the housing 100 and the communication interface 200, which plays a role of highly efficient waterproof and dustproof. An avoidance groove 3 is provided between adjacent sealing units 2, which is used to avoid the housing 100 part between the adjacent communication interfaces 200 located at the installation position of the printer housing 100. The purpose is to facilitate the demoulding of injection molding and save a certain amount of material when the silicone body 1 is designed as an integrated type, and provide deformation space while locking a single communication interface 200.

[0033] like Figure 3As shown, the sealing unit 2 includes a first sealing unit 21, a second sealing unit 22, a third sealing unit 23, a fourth sealing unit 24 and a fifth sealing unit 25, each of which is used to seal different types of communication interfaces 200. Specifically, the first sealing unit 21 is used to seal the network port. The second sealing unit 22 is used to seal the serial port. The third sealing unit 23 is used to seal the USB port. The fourth sealing unit is used to seal the wire box port. The fifth sealing unit 25 is used to seal the power interface.

[0034] like Figure 2 As shown, in order to increase the applicability of the waterproof structure, it can not only meet the requirements of sealing the continuous communication interface 200, but also take out each unit separately to seal the housing 100 in different fields, and increase the diversity of arrangements to seal the communication interface 200. A mortise and tenon structure 5 is set between adjacent sealing units 2 for detachable connection. The mortise and tenon structure 5 includes a boss 51 and a groove 52 adapted to the boss 51. The boss 51 is inserted along the direction of the groove 52. The groove 52 plays a role of guiding and limiting, and forms a flat outer surface.

[0035] Through such a mortise and tenon joint method, a variety of combinations can be achieved. When the same communication interface 200 needs to be sealed, only the same unit needs to be taken and connected by snapping the protruding column 51 into the groove 52. Different units can also be taken to achieve the sealing of communication interfaces 200 with different arrangements. This arrangement has good flexibility, strong applicability, and is quick and convenient.

[0036] like Figure 4 and Figure 5 As shown, when facing printers of different models or styles, the gaps left after the printer housing 100 and the communication interface 200 are assembled may be different. Even though the waterproof structure made of silicone material can be sealed by deformation, when encountering a smaller gap, forcibly squeezing to achieve sealing will cause damage to the housing 100 and the communication interface 200. In the face of such a problem, a filling slot 6 is provided on the sealing unit 2, and a number of adjustment sheets 7 are detachably arranged in the filling slot 6. The surface of the adjustment sheet 7 is provided with an opening 71 adapted to the accommodating space 4. In this way, when the thickness of the waterproof structure needs to be adjusted, part of the adjustment sheet 7 arranged in the filling slot 6 can be taken out, so that the thickness of the overall waterproof structure will become smaller, meeting the sealing requirements of smaller gaps. In order to better take out or put the adjustment sheet 7 into the filling slot 6, a protrusion 72 for lifting is provided on the adjustment sheet 7 to facilitate the user's operation.

[0037] When the gap between the printer and the communication interface 200 is too large, the sealing performance of the waterproof mechanism is greatly reduced, and the overall thickness needs to be increased. A cylindrical hanging column 8 is fixedly arranged on the surface of the sealing unit 2, and a hanging groove 9 for accommodating the hanging column 8 is provided on the surface of the adjusting sheet 7. In this way, the adjusting sheet 7 can not only be taken out to reduce the thickness of the waterproof structure, but also an adjusting sheet 7 can be set to increase the thickness of the waterproof structure. It is only necessary to snap the hanging groove 9 onto the hanging column 8, which is convenient and quick to operate, and further increases the applicability. The hanging groove 9 is L-shaped, and one end of the hanging groove 9 close to the upper edge of the adjusting sheet 7 is a narrow part 91 with a width of d, and the other end of the hanging groove 9 is a wide part 92 with a width of D. The width of the narrow part 91 gradually increases along the wide part 92, and the width d is equal to the diameter of the hanging column 8. The advantage of this arrangement is that it is convenient to operate in a smaller space without having to align the hanging column 8 and the hanging groove 9 with great effort. First, because the width of the wide portion 92 is greater than the diameter of the hanging column 8, the hanging column 8 can be accommodated in the hanging groove 9 by slightly aligning it, and then the adjustment piece 7 is moved along the L-shaped path to move the hanging column 8 to the narrow portion 91. Because the width of the narrow portion 91 is not greater than the diameter of the hanging column 8, the adjustment piece 7 can be fixed on the surface of the sealing unit 2 to increase the thickness of the entire waterproof structure. This allows adjustment in multiple situations. The material of the adjustment piece 7 is also a silicone sheet, which is easy to obtain and is also part of the waterproof structure. It can also be produced separately according to the size.

[0038] In summary, the utility model realizes the sealing between the printer housing 100 and the communication interface 200 by providing a rectangular silicone body 1, which is divided into five sealing units 2 for sealing the communication interface 200, and the sealing unit 2 is provided with a receiving space 4 for the card-connected communication interface 200, and an avoidance groove 3 is provided between adjacent sealing units 2. In order to increase the applicability of the entire product, each sealing unit 2 is set as a detachable structure, and in order to meet the sealing between different gaps, an adjustment sheet 7 is set to reduce and increase the thickness of the entire product. The entire product has a simple structure, good practicality, and convenient operation.

[0039] 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.
