Description

Plate fastening device

The invention provides a plate fastening device, in particular to a fastening device for stably fastening a predetermined plate through a rotary crimping method, assembling a driving rod body, a linkage rod body and a sliding catheter and a rotating card through a sliding space of the base The body is provided, and the driving rod body drives the interlocking rod body to extend out of the base, and the predetermined plate can be stably fastened.

According to the general board (board-to-board), when assembled and joined, it is locked by a positioning screw with a knob, a collar and a screw, and is used for a plate that can be used for a working machine or other board-to-board connection; The working machine needs to use the plate to lock the joint, and the plate can be assembled, locked and disassembled by the movable mechanism. When the power device is broken or damaged, or the rate adjusting device changes the speed and adjusts the plate, the plate is used. Dismounting for related maintenance and adjustment work, and the plate is locked by a plurality of positioning screws. Therefore, it is easy to cause the positioning screws to fall off or be lost during the disassembly process, and the plate cannot be re-locked back to the original position, which affects assembly. The inconvenience and trouble of dismantling the work.

Furthermore, with the continuous innovation and advancement of computer technology, the application level of computers or various electronic and electrical products is more extensive, and the functions of use are continuously expanded and increased. In computers or electronic and electrical products, they are separately assembled due to different functions. Various machines such as a disc player, a CD player, a burner, or a power supply, and various tools are assembled by screws to be locked on the frame of the main body, but the screw holes on the machine are small and on the frame. When the screw hole is not easy to position and the screw is locked, it must be used. The hand tool (screwdriver) is quite troublesome in operation, and because the screw is small in size, it is easy to be lost during disassembly and assembly, which affects the assembly work, so the manufacturer develops the lock structure A, which is fixed by the housing A1. On the frame B, the top lock A21 of the rotary lock lever A2 is used, and the rotary lock lever A2 is rotated to lock the screw A22 at the bottom, and is locked in the screw hole C3 of the two plates C1 and C2, although the lock structure can be avoided. A shortcoming of the loss, but the lock structure A is limited by the limit slot A23 and the limit slider A24 when the rotary pressure is applied, and only rotates between the distances of a half turn, and locks the bottom lock screw A22 into the two plates C1. In the screw hole C3 of C2, there are still some troubles and troubles in actual use and implementation, such as:

(1) The rotary lock lever A2 is restricted by the limit slot A23 and the limit slider A24, and the number of rotation turns is only half a turn. Then, the bottom lock screw A22 of the rotary screw A2 is locked into the screw hole C3 of the two plates C1 and C2. It is also a half circle. The lock is not correct and unstable. It may be loose or separated by the influence of external force.

(2) The rotary lock lever A2 is limited by the horizontal lateral limit slot A23 and the limit slider A24, and reciprocates in a half circle (about 180 degrees), but does not form a clamping or positioning. It is also susceptible to the repulsive force of the spring A25 sleeved on the rotary lock lever A2, so that the lock screw A22 exits the screw hole C3 of the two plates C1 and C2.

(3) When the rotary lock lever A2 is rotated by the buckle A21, the position and direction of the rotation of the bottom lock screw A22 cannot be recognized, and it is difficult to discriminate the lock. When the screw A22 is locked in the screw holes C3 of the two plates C1 and C2, the locking is not sure and loose.

(4) The top of the rotating screw A2 is provided with a buckle A21 for rotation, but because the ring buckle A21 is small in size and the position for grasping is not much, it is difficult to hold, and the A2 is quite inconvenient when the rotating screw is rotated.

(5) The locking screw A22 at the bottom of the rotary lock lever A2 locks the screw hole C3 of the two plates C1 and C2 because the thickness of the screw hole C3 is thin and the contact with the lock screw A22 is small, resulting in locking Insufficient strength and considerable loss of detachment.

Therefore, how to solve the problem between the internal frame and the plate of the mainframe, the locking structure of the lock structure is not sure, easy to loosen, and the rotation lock is only half a circle, and the combination of the two plates is locked.
