Description

Improved structure of the fixture

The creation system provides an improved structure of the fixing device, especially when the fixing device is assembled, does not shake, and is smoothly installed, and uses the positioning sleeve for the locking component to be worn, and the outer sleeve is sleeved. After being clamped, the card sleeve is pushed into the outer sleeve of the positioning sleeve for quick assembly of the fixing device.

When the general panel (board-to-board) is combined, it is locked by using a positioning screw equipped with a knob, a collar and a screw, and the screw and the collar are fixed on the first panel, and the knob is rotated. The screw is locked into the second panel to form a preset position, and after the screw is locked by the hand tool, the first panel is locked and fixed to the second panel, and can be used in the working machine or other board. Used on boards that are joined to the board.

Furthermore, some manufacturers have developed such a floating screw composed of a cap, a screw and a positioning seat, which is to fasten the positioning seat of the floating screw to the perforation of the plate, and then use the screw to lock the other screw. The plate is fixed, and when the user removes the plate, the floating screw can still be fixed in the perforation of the plate through the positioning seat without being lost by the user.

Please refer to the ninth figure, which is a side cross-sectional view of a conventional fixing device. It can be clearly seen from the figure that the conventional fixing device is equipped with a locking member B in the sleeve A, and the sleeve A is externally sleeved. Elastomer A1, with elastomer A1 The side abuts against the stop collar A2 on the sleeve A, and the other side of the elastic body A1 abuts against the inner side of the cap B1 of the lock member B, and then the head B1 of the lock member B is The side-extending screw B2, which is inserted into the accommodating space A0 inside the sleeve A, can be stopped by the stopper B3 of the sleeve A located inside the accommodating space A0, and blocked by the screw B2 of the lock B Between the sleeve A and the screw B2 of the lock member B, the screw B2 of the lock member B is inserted out of the outer space A0 of the sleeve A, and a nut C is locked to the screw B2, so that the sleeve A is located at the stop projection. The welding section A4 of the bottom of the ring A2 is welded on the plate D, and is locked and integrated with the other matching plate by the locking member B.

Although this method can prevent the sleeve A from being welded on the plate D, the gap between the sleeve A and the lock member B is offset or shaken to prevent the lock member B from being locked to another fit. The problem of wear and disintegration caused by the perforation (not shown) on the plate D collides with the plate D, which is not easy to cause damage and damage on the structure of the plate D, but the sleeve A is bonded to the plate D for welding. During the operation, after the solder layer is heated and melted by the tin furnace, the tin liquid will penetrate into the nut C and the screw B2 along the small gap between the sleeve A and the perforation, so that after passing through the tin furnace, The threaded section of the screw B2 and the nut C is easily blocked or jammed, and the operator may cause the hand tool and the nut when the nut C is detached from the screw B2 of the locker B by the tool. The outer edge of the C produces a slip condition, or the threaded section of the nut C and the screw B2 are interlocked to form a wear phenomenon, which causes inconvenience and difficulty in the disassembly of the nut C, and the overall labor and cost are relatively increased, and the Re-established in this industry It can be effectively solved.
