[0015] 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.

[0016] Please see Figure 1-5 This utility model provides a technical solution: an expandable plug-in card gateway device, including a body 1, a heat dissipation hole 2 on one side surface of the body 1, a mounting hole 3 on one side surface of the body 1, a lower latching groove 4 and an upper latching groove 5 on one side surface of the body 1, a sliding groove 6 on one side surface of the body 1, a rectangular groove 7 on one side surface of the body 1, a circular groove 8 on one side surface of the body 1, a circular hole 9 on one side surface of the body 1, a sliding hole 10 on one side surface of the body 1, and a disassembly and assembly mechanism 11 is provided on the inner surface of the rectangular groove 7; The disassembly / assembly mechanism 11 includes a rectangular block 1101 and a round rod 1102. The rectangular block 1101 is slidably connected to the inner surface of the rectangular groove 7, and the round rod 1102 is slidably connected to the inner surface of the circular hole 9. A retainer 1103 is fixedly connected to one side surface of the rectangular block 1101. A first retaining groove 1104 and a second retaining groove 1105 are formed on one side surface of the retainer 1103. A round block 1106 is fixedly connected to the outer surface of the round rod 1102, and a spring 1107 is slidably connected to the outer side of the round rod 1102. The round rod 1102 is located away from the round block. A pull block 1108 is fixedly connected to one end of 1106. A protrusion 1109 is fixedly connected to one side surface of the pull block 1108. A fixing hole 1110 is opened on one side surface of the rectangular block 1101. Through the arrangement of the rectangular block 1101, the round rod 1102, the card seat 1103, the first card slot 1104, the second card slot 1105, the round block 1106, the spring 1107, the pull block 1108, the protrusion 1109, and the fixing hole 1110, when in use, pulling the pull block 1108 will cause the round rod 1102 and the round block 1106 to slide along the round hole 9. The circular block 1106 compresses the spring 1107. As the circular rod 1102 moves, the end of the circular rod 1102 away from the pull block 1108 gradually disengages from the fixing hole 1110 of the rectangular block 1101. The rectangular block 1101 loses its limit and unlocks. After unlocking, push or pull the card holder 1103. Because the card holder 1103 is fixed to the rectangular block 1101 and the rectangular block 1101 is slidably connected in the rectangular groove 7, the card holder 1103 will slide stably in the sliding groove 6 along the trajectory of the rectangular groove 7. After pulling the card holder 1103 out of the sliding groove 6, the first card slot 1104 of the card holder 1103 or After cleaning and maintenance of the second slot 1105, push the card holder 1103 back into the sliding groove 6, release the spring 1107 compressed by the pull block 1108 to release the elastic force and push the circular block 1106 to reset. The circular block 1106 drives the circular rod 1102 through the fixing hole 1110 of the rectangular block 1101 and connects with the circular groove 8, thus completing the locking of the rectangular block 1101 and the card holder 1103. At the same time, the protrusion 1109 of the pull block 1108 can increase the friction of the hand to facilitate operation. The operator can quickly remove the card holder 1103 for cleaning and maintenance, avoiding the extended maintenance time caused by disassembling the whole machine.

[0017] Furthermore, the lower locking groove 4 and the upper locking groove 5 are the same size and are symmetrically distributed along the vertical central axis of the sliding groove 6. The inner wall size of the sliding groove 6 is adapted to the outer wall size of the card holder 1103. Through the setting of the sliding groove 6 and the card holder 1103, the inner wall size of the sliding groove 6 is precisely adapted to the outer wall size of the card holder 1103 during use. When the operator pushes or pulls the card holder 1103, the sliding groove 6 can provide a stable sliding trajectory for the card holder 1103, avoiding the card holder 1103 from deviating, jamming or tilting.

[0018] Furthermore, two rectangular grooves 7 of the same size are provided and are symmetrically distributed along the horizontal central axis of the sliding groove 6. Two rectangular blocks 1101 of the same size are provided and are symmetrically distributed along the horizontal central axis of the card holder 1103. The inner wall size of the rectangular groove 7 is adapted to the outer wall size of the rectangular block 1101. Through the setting of the rectangular groove 7 and the rectangular block 1101, when the card holder 1103 is pulled or pushed during use, the cooperation between the rectangular block 1101 and the rectangular groove 7 can assist the card holder 1103 to accurately reset, providing a stable foundation for subsequent fixation.

[0019] Furthermore, two circular holes 9 of the same size are provided and are symmetrically distributed along the vertical central axis of the sliding groove 6. Two circular rods 1102 of the same size are provided and are symmetrically distributed along the horizontal central axis of the pull block 1108. The inner wall of the circular hole 9 is adapted to the outer wall of the circular rod 1102. With the arrangement of the circular hole 9 and the circular rod 1102, when the pull block 1108 is pulled to unlock or released to lock, the circular rod 1102 can slide smoothly along the inner wall of the circular hole 9, ensuring the stable operation of the mechanism.

[0020] Furthermore, two springs 1107 and two circular blocks 1106 of the same size are provided, and two sliding holes 10 of the same size are provided, symmetrically distributed along the vertical central axis of the sliding groove 6. The outer wall dimensions of the springs 1107 and the circular blocks 1106 are adapted to the inner wall dimensions of the sliding holes 10. The circular holes 9 and the sliding holes 10 are connected. Through the arrangement of the sliding holes 10, the springs 1107 and the circular blocks 1106, during use, the circular blocks 1106 always slide along the inner wall of the sliding holes 10 without lateral displacement. The springs 1107 are also confined within the sliding holes 10 to prevent the elastic force from failing due to twisting or misalignment during compression or extension.

[0021] Furthermore, multiple protrusions 1109 of the same size are provided, and the vertical central axes of the round rod 1102, the round block 1106 and the spring 1107 coincide. Through the provision of protrusions 1109, multiple protrusions 1109 can increase the friction between the hand and the pull block 1108 during use, ensuring a smoother operation.

[0022] Furthermore, the inner wall size of the fixing hole 1110 is adapted to the outer wall size of the round rod 1102, and the heat dissipation hole 2 is provided with multiple holes of the same size. Through the setting of the fixing hole 1110 and the round rod 1102, the round rod 1102 can be accurately embedded in the fixing hole 1110 to form a stable connection during use, and restrict the rectangular block 1101 to ensure that the card holder 1103 is not easy to fall off.

[0023] Working principle: The operator pulls the pull block 1108 outward. The pull block 1108 drives the fixed round rod 1102 and the round block 1106 to slide along the round hole 9. When the round block 1106 moves, it compresses the spring 1107. As the round rod 1102 moves, the end of the round rod 1102 away from the pull block 1108 gradually disengages from the fixing hole 1110 of the rectangular block 1101. The rectangular block 1101 loses its limit and unlocks. After unlocking, the holder 1103 is pushed or pulled. Because the holder 1103 is fixed to the rectangular block 1101 and the rectangular block 1101 is slidably connected in the rectangular groove 7, the holder 1103 will slide stably in the sliding groove 6 along the trajectory of the rectangular groove 7. After pulling the holder 1103 out of the sliding groove 6... The first card slot 1104 or the second card slot 1105 of the card holder 1103 can be maintained and cleaned. Then, the card holder 1103 is pushed back into the sliding groove 6. The spring 1107 compressed by the pull block 1108 is released to push the circular block 1106 back to its original position. The circular block 1106 drives the circular rod 1102 through the fixing hole 1110 of the rectangular block 1101 and connects with the circular groove 8, thus completing the locking of the rectangular block 1101 and the card holder 1103. At the same time, the protrusion 1109 of the pull block 1108 can increase the friction of the hand to facilitate operation. The lower locking groove 4 and the upper locking groove 5 can help to position the hand to apply force. The mounting hole 3 can be used to fix the device as a whole. This completes the use process of an expandable plug-in card gateway device.
