[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1-5 The card reader shown includes a card reader body 1, and further includes a sealing component and a fixing component;

[0023] Specifically, the card reader body 1 has multiple memory card slots 103 on one side, and the data output terminal of the card reader body 1 is electrically connected to a data connection cable 102, which is used to connect the card reader body 1 to the smart device.

[0024] It should be noted that the working principle of the overall reference model CR125 card reader consisting of the card reader body 1, memory card slot 103 and data connection cable 102 is as follows:

[0025] Specifically, the sealing component is used to seal and isolate the card reader body 1. The sealing component includes a bottom shell 2 disposed at the bottom of the card reader body 1. The inner wall of the bottom shell 2 is symmetrically provided with limiting parts for fixing the card reader body 1. The top of the card reader body 1 is provided with a top cover 3 for sealing the card reader body 1. The connection between the bottom shell 2 and the card reader body 1 is provided with an insertion part for fixing the bottom shell 2.

[0026] It should be noted that both the bottom shell 2 and the top cover 3 are made of polypropylene. The interlocking part includes a limiting strip 101 symmetrically arranged on the side of the card reader body 1. The inner wall of the bottom shell 2 is symmetrically provided with limiting grooves 203 for the interlocking of the limiting strip 101.

[0027] Specifically, there are 4 limiting strips 101 and 4 limiting grooves 203. The limiting strips 101 and the card reader body 1 are glued together. The interlocking of the limiting strips 101 and the limiting grooves 203 restricts the position of the card reader body 1 and the bottom shell 2, preventing misalignment of the card reader body 1 and the bottom shell 2, and facilitating their positioning and alignment.

[0028] The limiting part includes a fixing post 202 disposed on the inner wall of the bottom shell 2, the end of the fixing post 202 being inserted and connected to the side of the card reader body 1, and the inner wall of the top cover 3 being symmetrically provided with positioning posts 302 for fixing the card reader body 1.

[0029] Specifically, a positioning ring groove 2021 is provided at the end of the fixing post 202. The positioning ring groove 2021 is used to limit the insertion depth of the card reader body 1. The fixing post 202 and the bottom shell 2 are integrally injection molded. The fixing post 202 and the positioning post 302 are aligned. The cross-sectional radius of the through hole of the card reader body 1 for the fixing post 202 to pass through is smaller than the cross-sectional radius of the positioning post 302. The positioning post 302 contacts the card reader body 1 to prevent the card reader body 1 from disengaging from the positioning ring groove 2021.

[0030] The fixing component is used to connect and fix the bottom shell 2 and the top cover 3. The fixing component includes multiple sets of snap-fit ​​brackets 201 symmetrically arranged on the inner wall of the bottom shell 2, multiple sets of inserts 301 symmetrically arranged on the inner wall of the top cover 3, the top of the inserts 301 is provided with an oblique protrusion 3011, the side of the snap-fit ​​bracket 201 is provided with a snap-fit ​​groove 2011 for snapping with the oblique protrusion 3011, and the inner wall of the top cover 3 is provided with a positioning part for supporting the position of the top cover 3.

[0031] It should be noted that the snap-fit ​​bracket 201 and the bottom shell 2 are integrally injection molded, and the insert strip 301 and the top cover 3 are integrally injection molded. The oblique protrusion 3011 at the end of the insert strip 301 enters the snap-fit ​​groove 2011 by pressing, and the oblique protrusion 3011 can be disengaged from the snap-fit ​​groove 2011 after external force is applied.

[0032] Specifically, the positioning part includes a reinforcing ring 303 disposed on the inner wall of the top cover 3, and the snap-fit ​​bracket 201 and the inner wall of the bottom shell 2 have rectangular grooves for the reinforcing ring 303 to pass through.

[0033] It should be noted that the reinforcing ring 303 and the top cover 3 are integrally injection molded, and its interpenetration with the rectangular groove restricts the position of the top cover 3 and the card reader body 1.

[0034] In actual use, a bottom shell 2 and a top cover 3 are provided on the outside of the card reader body 1. The two are inserted into the snap-fit ​​groove 2011 of the snap-fit ​​bracket 201 on the inner wall of the bottom shell 2 through the oblique protrusion 3011 at the end of the insert strip 301 on the inner wall of the top cover 3. Thus, the bottom shell 2 and the top cover 3 can wrap and protect the card reader body 1. Compared with the existing one-piece molded shell card reader, this detachable shell is convenient for manufacturers to disassemble and customize the card reader shell in the later stage.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
