[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. When producing and assembling a data expansion dock, the present invention uses a clamping plate to clamp a circuit board, and multiple clamping plates can be combined together, which is beneficial to fixing multiple clamping plates so that the gap between the outer shell and the circuit board can be filled when the clamping plate is subsequently moved to the inside of the outer shell and the circuit board. The clamping plate fixed as a whole can ensure that the gap is completely filled, and avoid the clamping plate moving upward under the friction of the inner wall of the outer shell when the clamping plate moves between the outer shell and the circuit board. In addition, the detection rod and the toggle rod can adjust the number of clamping plates combined according to the size of the outer shell, which is beneficial to automatically detect the size of the gap between the circuit board and the outer shell, thereby changing the thickness of the clamping plates combined together, ensuring that the clamping plates combined together can fill the gap, and avoiding the gap between the circuit board and the outer shell being different in size, and the combined clamping plates cannot be changed, resulting in the inability to fill the gap, affecting the assembly of the expansion dock.

[0015] 2. During the assembly of the expansion dock of the present invention, when the detection rod acts on the shell to move, after the shell moves to the bottom of the circuit board, the edge of the shell will act on the detection rod and the toggle rod to move. When the toggle rod on one side moves, it will drive the driving rod to move together. The movement of the driving rod will drive the driving rod on the opposite side to move together through the driving column, thereby driving the toggle rod and the detection rod on the opposite side to move. The detection rods and toggle rods on both sides can move at the same time. When the shell deviates to one side, the shell will act on the detection rod to move, and the detection rods on both sides will move, and a gap will appear between the detection rod on the other side and the shell. Then the detection rod continues to move downward, and the shell will move back to under the circuit board, which is conducive to making the toggle rods on the opposite sides move the same distance, ensuring that the thickness of the combined clamping plate is the same as the gap between the shell and the circuit board, avoiding the toggle rods on both sides from moving different distances, thereby causing the circuit board to be unable to be in the middle position of the shell, thereby affecting the assembly of the expansion dock.

[0016] 3. In the present invention, when the toggle lever moves to the inside of the shell, the elastic block on the surface of the clamping plate close to the inside of the shell can contact the inside of the shell, which is conducive to the clamping plate filling the gap between the shell and the circuit board, avoiding the situation where the spacing between the shell and the circuit board cannot meet the multiple of the clamping plate. After the clamping plate moves between the shell and the circuit board, there is still a gap between the clamping plate and the shell, affecting the assembly of the expansion dock.

[0035] When producing and assembling the data expansion dock, the shell will be transported to the assembly station, and then the external driver will drive the adjustment plate 1 to move above the circuit board to be assembled. Then the adjustment plate 1 changes so that the clamping plate 3 is located on the outside of the circuit board. Then the adjustment plate 1 moves down so that the circuit board is located between the clamping plates 3. The adjustment plate 1 shrinks and moves upward, and the circuit board moves to above the blocking block 4. The blocking block 4 can block the circuit board to prevent the circuit board from detaching from the clamping plate 3 when the adjustment plate 1 is not completely changed, causing damage to the circuit board and affecting the subsequent use of the product. Then, in the process of the clamping plate 3 clamping the circuit board, the circuit board will act on the extrusion block 5. The movement of the extrusion block 5 will cause the hanging plate 8 to rotate. The hanging plate 8 will move to the upper end of the support plate 7, and then the extrusion block 5 will move. When it reaches the top of the hanging plate 8, the hanging plate 8 will fit with the supporting plate 7, and the movement of the extrusion block 5 will act on the extrusion blocks 5 on the surfaces of the other clamping plates 3. The supporting plate 7 fits with the scraper and the extrusion block 5 will block the scraper, which is conducive to fixing multiple clamping plates 3, so that when the subsequent clamping plates 3 are moved to the inside of the shell and the circuit board, the gap between the shell and the circuit board can be filled, and the clamping plates 3 fixed as a whole can ensure that the gap is completely filled, avoiding that when the clamping plates 3 are moved between the shell and the circuit board, the clamping plates 3 will move upward under the friction of the inner wall of the shell, resulting in the clamping plates 3 not being able to move completely between the shell and the circuit board, thereby resulting in the gap not being able to be completely filled. In the subsequent installation process, the circuit board will move out of place, affecting the assembly process, and then adjust After the plate 1 drives the circuit board to move above the shell, it will drive the clamping plate 3 and the circuit board to move downward, and the toggle rod 10 and the detection rod 11 will move together, and the bottom of the detection rod 11 will extend into the shell, and then the detection rod 11 continues to move downward, and the bottom of the detection rod 11 will act on the shell to move, and the detection rod 11 in four directions will move the shell to just below the circuit board, and then the detection rod 11 continues to move downward, and the shell will act on the detection rod 11 to move into the shell, and the bottom of the detection rod 11 can shrink, and the detection rod 11 will drive the toggle rod 10 to move into the shell together, and when the toggle rod 10 moves to the position of the swing rod 13, the toggle rod 10 will act on the swing rod 13 to rotate, and the rotation of the swing rod 13 will drive the support plate 7 to move into the first slide groove 6, and the hanging plate 8 It will disengage from the support plate 7, and then when the toggle rod 10 moves into the interior of the shell, the distance between the toggle rod 10 and the innermost clamping plate 3 is the distance of the gap between the shell and the circuit board, and the clamping plate 3 passed by the toggle rod 10 will be released, which is conducive to automatically detecting the size of the gap between the circuit board and the shell, thereby changing the thickness of the clamping plates 3 merged together, ensuring that the clamping plates 3 merged together can fill the gap, and avoiding the gap between the circuit board and the shell being different in size, and the merged clamping plates 3 cannot be changed, resulting in the inability to fill the gap, affecting the assembly of the expansion dock, and then when the circuit board moves into the shell, the clamping plate 3 located at the edge of the shell will move upward under the action of the shell, and the clamping plate 3 located inside the shell can move into the shell.

[0036] During the assembly of the expansion dock, the detection rod 11 and the toggle rod 10 on the opposite sides move at different distances, which will cause the circuit board to deviate to one side in the shell. As a further solution of the present invention, the upper end of the toggle rod 10 is fixedly connected to a driving rod 14, which extends to the inside of the four adjustment plates 1. A driving column 15 is engaged between the two driving rods 14 at the upper ends of the opposite adjustment plates 1, and the driving rod 14 can act on the driving column 15; during the assembly of the expansion dock, when the detection rod 11 acts on the shell to move, after the shell moves to the bottom of the circuit board, the edge of the shell will act on the detection rod 11 and the toggle rod 10 to move, and when the toggle rod 10 on one side moves, it will drive the driving rod 14 to move together, and the movement of the driving rod 14 will be driven by the driving column 15 The driving rod 14 on the opposite side moves together, thereby driving the toggle rod 10 and the detection rod 11 on the opposite side to move. The detection rods 11 and the toggle rod 10 on both sides can move at the same time. When the shell deviates to one side, the shell will act on the detection rod 11 to move, and the detection rods 11 on both sides will move. A gap will appear between the detection rod 11 on the other side and the shell. Then the detection rod 11 continues to move downward, and the shell will move back to under the circuit board, which is conducive to making the toggle rods 10 on the opposite sides move the same distance, ensuring that the thickness of the combined clamping plate 3 is the same as the gap between the shell and the circuit board, avoiding the toggle rods 10 on both sides from moving different distances, which will cause the circuit board to not be in the middle position of the shell, thereby affecting the assembly of the expansion dock.

[0037] When the clamping plate 3 moves between the outer shell and the circuit board, and the spacing between the outer shell and the circuit board does not meet the multiple of the thickness of the clamping plate 3, a gap will be left between the clamping plate 3 and the outer shell. As a further solution of the present invention, a triangular elastic block 16 is provided on the surface of the clamping plate 3 away from the blocking block 4; when the toggle rod 10 moves to the inside of the outer shell, the elastic block 16 on the surface of the clamping plate 3 close to the inside of the outer shell can contact the inside of the outer shell, which is conducive to the clamping plate 3 filling the gap between the outer shell and the circuit board, avoiding the situation where the spacing between the outer shell and the circuit board cannot meet the multiple of the clamping plate 3, and after the clamping plate 3 moves to between the outer shell and the circuit board, there is still a gap between the clamping plate 3 and the outer shell, affecting the assembly of the expansion dock.

[0038] After the docking station is assembled, it is inconvenient to take out the clamping plate 3. As a further solution of the present invention, a groove 17 is provided inside the clamping plate 3. The upper end of the groove 17 passes through the two side surfaces of the clamping plate 3. The bottom of the groove 17 extends to the position of the blocking block 4 and the elastic block 16. A sliding rod 18 is elastically slidably connected inside the groove 17. The upper end of the sliding rod 18 extends to the outside of the clamping plate 3. The upper ends of the sliding rods 18 inside the clamping plates 3 are staggered and overlapped. The blocking block 4 and the elastic block 16 are both provided with a third sliding groove 1 on one side close to the sliding rod 18. 9, the third slide groove 19 is an inclined groove; after the expansion dock is assembled, press the sliding rod 18 downward, the sliding rod 18 will slide downward inside the groove 17, and the end of the sliding rod 18 will slide in the third slide groove 19, and the blocking block 4 and the elastic block 16 will move toward the inside of the groove 17 under the action of the sliding rod 18 and the third slide groove 19, which is conducive to disengaging the blocking block 4 from the circuit board and separating the elastic block 16 from the inside of the shell, making it easy to take out the clamping plate 3 for subsequent assembly, avoiding the cumbersome removal of the clamping plate 3 and affecting the assembly efficiency of the expansion dock.

[0039] When taking out the clamping plate 3, manual operation is required to press the sliding rod 18, which increases the workload of workers, and the movement of the adjusting plate 1 is prone to cause safety hazards. As a further solution of the present invention, a pressure plate 20 is slidably connected to the surface of the adjusting plate 1, and the pressure plate 20 is located above the sliding rod 18. The pressure plate 20 can act on the sliding rod 18. An external mounting device is provided above the adjusting rod, and the mounting device can install screws on the circuit board, and the mounting device can act on the pressure plate 20; after the circuit board is moved to the inside of the shell, the external mounting device will install the screws on the circuit board. When the mounting device is moved and installed to the position of the clamping plate 3, when the mounting device completes the installation of the screws, the mounting device will act on the pressure plate 20 downward, and the downward movement of the pressure plate 20 will act on the sliding rod 18 to move downward, which is conducive to automatically triggering the sliding rod 18 after the screw is installed, releasing the clamping of the clamping plate 3, reducing manual workload, and avoiding manual movement near the adjusting plate 1, eliminating the occurrence of safety hazards.
