[0019] 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.

[0020] Please see Figure 1-4 This utility model provides two technical solutions:

[0021] Example 1: A split-type reader housing includes a main housing 1, heat dissipation mechanisms 2 are provided on both sides inside the main housing 1, a cover 3 is provided on the top of the main housing 1, a connecting seat 301 is installed on one side of the bottom of the cover 3, a limiting mechanism 4 is provided around the bottom of the cover 3, a material layer 5 is provided inside the main housing 1, and rubber pads are provided on the connecting surfaces of the main housing 1 and the cover 3 to ensure the sealing of the connection between the main housing 1 and the cover 3. At the same time, the heat dissipation mechanism 2 is inserted inside the main housing 1, and when the main housing 1 and the cover 3 are separated, the heat dissipation mechanism 2 can be maintained and replaced.

[0022] The heat dissipation mechanism 2 includes a transmission chamber 201 located on both sides inside the main housing 1. Heat dissipation fans 202 are evenly installed at equal intervals inside the transmission chamber 201. Filter plates 203 are fixedly connected to both sides inside the transmission chamber 201. Limiting blocks 204 are fixedly connected to both sides of the transmission chamber 201. The limiting blocks 204 located on both sides of the transmission chamber 201 can be inserted into the main housing 1. At the same time, when the heat dissipation fans 202 inside the heat dissipation mechanism 2 are activated, they can accelerate the input of external air into the main housing 1 and dissipate heat from the reader inside the main housing 1.

[0023] The limiting mechanism 4 includes a slot 101 located around the top of the main housing 1. The slot 101 has slots 102 on both sides inside. The bottom of the cover 3 has a fixed plug 302 that engages with the slot 101. When the plug 302 on the cover 3 is inserted into the slot 101 on the main housing 1, and the plugs 405 on both sides of the plug 302 are inserted into the slots 102 on the slot 101, the connection and assembly of the main housing 1 and the cover 3 can be completed.

[0024] A handle 401 that rotates within the insert block 302 is rotatably connected to the top perimeter of the cover 3. Pull ropes 402 are fixedly connected to the bottom ends of both sides of the handle 401. A movable plate 403 is fixedly connected to one side of the pull ropes 402. A spring 404 is fixedly connected to the middle of the two movable plates 403. A locking block 405 is fixedly connected to the side of the movable plate 403 away from the spring 404. When the locking block 405 is subjected to an upward force, it can squeeze the spring 404 through the movable plate 403. At this time, the locking block 405 can be retracted into the insert block 302. Rotating the handle 401 can drive the pull ropes 402 on both sides to wind up. At this time, the pull ropes 402 can be moved by pulling the locking block 405 through the movable plate 403.

[0025] Example 2 differs from Example 1 mainly in that:

[0026] A split-type reader shell includes a heat-conducting layer 501 disposed in the middle of the main shell 1 in the material layer 5, a protective layer 502 disposed inside the heat-conducting layer 501, and a strength layer 503 disposed outside the heat-conducting layer 501.

[0027] The heat-conducting layer 501 is made of aluminum-magnesium alloy, which has good thermal conductivity and can quickly dissipate the heat generated by the electronic components inside the reader, preventing heat accumulation that could lead to a decrease in device performance or malfunction. At the same time, the aluminum-magnesium alloy can effectively shield external electromagnetic interference, preventing external electromagnetic fields from affecting the internal circuitry of the reader, and also preventing the electromagnetic radiation generated by the reader itself from interfering with the surrounding environment and other devices.

[0028] The protective layer 502 is made of polyamide, which has high hardness and wear resistance. It can resist the friction between the internal electronic components of the reader and the shell, prevent damage to the electronic components caused by wear and tear from long-term use, and effectively isolate the internal electronic components of the reader from the shell to prevent safety hazards such as leakage. At the same time, it has good resistance to many chemicals and is not easily corroded by chemicals such as acids and alkalis. Even when used in environments with chemical pollution, it can maintain the stability of the shell's performance.

[0029] The strength layer 503 is made of polycarbonate, which has high strength and high toughness. It can effectively resist external collisions and impacts and protect the electronic components inside the reader from damage. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0030] In use, the reader / writer can be installed inside the main housing 1. The top of the main housing 1 has four slots 101 corresponding to the bottom inserts 302 of the cover 3. When the insert 302 on the cover 3 is inserted into the slot 101 on the main housing 1, the locking blocks 405 on both sides of the insert 302 are compressed by the movable plate 403, causing the locking blocks 405 to retract into the insert 302. When the bottom insert 302 of the main housing 1 is fully inserted into the slot 101, the locking blocks 405 are released from pressure. Due to the reaction force of the compressed spring 404, the movable plate 403 pushes the locking blocks 405 into the slots 102 of the slot 101, completing the connection and assembly between the main housing 1 and the cover 3. Simultaneously, the cooling fan 202 inside the transmission chamber 201 is activated, blowing external air into the main housing 1 and cooling the reader / writer inside.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
