The terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; "connected" can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0034] The utility model is mainly used in a damp and dark environment to prevent the chip of a personnel positioning card from being oxidized.

[0035] like Figures 1 to 7 As shown, this embodiment provides a waterproof and moisture-proof personnel positioning card 100, including an outer shell 30, and a chip 40 arranged in the outer shell 30, and the chip 40 is provided with a contact 401 and a coil 402 (RFID coil); the RFID coil is used to receive and send wireless signals to realize the positioning function.

[0036] When the personnel positioning card is used for a long time in a relatively humid environment, there may be a gap between the upper and lower ends of the card body when they are buckled together, which may cause poor sealing. This will cause humid air to penetrate into the card body, thus affecting its performance and accuracy. To solve the above technical problems, please refer to Figures 1 to 7 As shown, a mounting groove 301 and a connecting groove 302 are provided inside the outer shell 30 , a connecting member 303 is provided inside the mounting groove 301 , a cavity is formed inside the connecting member 303 , and a movable plate 3033 is provided inside the cavity.

[0037] Furthermore, the cavity is divided into two groups of grooves by the movable plate 3033, namely the contraction groove and the clamping groove 3032, and the cross section of the clamping groove 3032 is convex.

[0038] Furthermore, an upper shell 10 is disposed in the outer shell 30, and an elastic ring 50 is disposed around the upper shell 10 along its circumference, and the top of the elastic ring 50 has an inclined end surface that gradually tilts downward, and the inclination angle of the inclined end surface is 12° to 26°.

[0039] Furthermore, the elastic rings 50 located at both ends of the upper shell 10x extend into the connecting groove 302 provided on the outer shell 30 and fill the connecting groove 302. The cross-sectional shape of the connecting groove 302 is opened according to the shape of the elastic ring 50, so that the outer wall of the elastic ring 50 conflicts with the inner wall of the connecting groove 302.

[0040] Furthermore, the elastic ring 50 is made of an elastic material, and by utilizing the elasticity of the elastic material itself, the elastic ring can completely fill the connecting groove 302 after being extended into the connecting groove 302 .

[0041] Furthermore, a sealing member 60 is provided on the elastic ring 50 at both ends of the upper shell in the Y direction, and the sealing member 60 and the elastic ring 50 are integrated, a clamping block 601 is provided on the sealing member 60, and the clamping block extends into the clamping groove 3032, and the clamping block 601 is in contact with the inner wall of the clamping groove 3032.

[0042] Furthermore, the depth of the connection grooves at both ends of the outer shell in the Y direction is greater than the depth of the connection grooves at both ends of the outer shell in the X direction.

[0043] In this embodiment, when the upper shell 10 is snapped into the outer shell 30, the elastic ring 50 provided on the upper shell 10 is snapped into the connecting groove 302, and at the same time, the snap-in block 601 of the seal installed on the elastic ring 50 is automatically snapped into the snap-in groove 3032, thereby making the upper shell 10 and the outer shell 30 sealed and connected, thereby improving their sealing, preventing humid air from entering the interior of the personnel positioning card, and increasing the service life of the product.

[0044] In actual application, in order to ensure that the card block can extend into the card slot, the card block completely fills the card slot to make it sealed. Figure 4 As shown, the movable plate 3033 is slidably installed in the cavity, so that the movable plate 3033 can move in the cavity of the connecting member 303. A guide rail is arranged at the top of the movable plate 3033, and a slide groove for the guide rail to extend into is opened on the inner wall of the top of the cavity, so that the guide rail is installed in the slide groove.

[0045] An elastic component 3034 is fixedly mounted on the end surface of the movable plate 3033 away from the clamping groove 3032, and the elastic component 3034 is preferably a spring.

[0046] In this embodiment, when the clamping block 601 is inserted into the clamping slot 3032, the clamping block 601 generates a thrust, which pushes the movable plate 3033 toward the position of the elastic component 3034 and compresses the elastic component 3034. When disassembly is required, the clamping block is pulled out of the clamping slot 3032 by force or with a disassembly tool, and the movable plate 3033 is driven to rebound to the original position by the rebound force of the spring.

[0047] In actual application, in order to further improve the overall waterproofness, the outer walls of the upper shell 10 and the outer shell 30 are sprayed with waterproof materials, such as polyurethane, to form a waterproof layer.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not restrictive. Although the utility model is described in detail with reference to the embodiments, it should be understood by those skilled in the art that any modification or equivalent replacement of the technical solution of the utility model does not deviate from the spirit and scope of the technical solution of the utility model, and should be included in the scope of the claims of the utility model.
