Description

Floating fixture

The present invention provides a floating fixing device, in particular, a floating state that allows the shaft of a locking element to move in a horizontal or vertical direction in the limit space formed by the butting portion and the accommodating groove, and the locking element The shaft is inclined with the stopper as the fulcrum, so that the floating fixing device of the present invention has the corrective ability of inclined locking when combined with the preset first and second plates.

Press, when assembling and joining common plates (board-to-board), they usually use positioning screws with knobs, collars and screws for locking. The assembly procedure is to fix the screws and collars on the outer panel first, and then screw them. Turn the knob to lock the screw into the inner panel to form a preset position, and then use a hand tool to lock the screw, then the outer panel and the inner panel are locked into one body. The locking mode of this multi-layer board body, It can be used in the field of machine tools or other board-to-board connection plates.

However, these machine tools require the use of plates to lock the joints, most of which are power devices or speed adjustment devices. Various power devices and speed adjustment devices are located inside the space formed by the machine shell, which can be assembled using the plates. , Locking, and disassembly methods. When the power plant crashes, fails, or is damaged, or when the speed adjustment device performs speed changes or adjustments, the plates are removed for related maintenance and adjustment operations, and the plates are through the plural The positioning screw is locked, so it is easy to cause the positioning screw to fall off and lose during the disassembly process, and it is impossible to re-lock the plate back to the original position, which will cause inconvenience and troubles in the assembly and disassembly operations. Some operators solve the problem of fixing the screw The shortcomings are easy to lose. A fixing device composed of a cap, a screw part and a positioning seat is developed. The positioning seat of the fixing device is first fastened in the perforation of the plate, and then the screw part is used to lock it to another plate. Form a fixation, and when the user unloads the board, the fixing device can still be fixed in the perforation of the board through the positioning seat, so that the fixing device will not fall off or lose, but the assembly process must still be operated or operated by the user. Hand tools (such as screwdrivers or wrenches, etc.) are used to control the locking or disassembly of the fixing device. There are still many shortcomings and problems in practical applications.

When the above-mentioned fixing device is in the locking operation, due to the design without any floating lock structure, when the screw part is accidentally locked into the plate at an oblique angle, there is no way to remedy it. It can only be unlocked and re-aligned and locked, and at the same time on the plate. Leaving defective keyholes. For product assembly lines that require fast operation, the process of locking, disassembling and re-locking takes too much time. For companies that pay attention to product production efficiency, the aforementioned factors that slow down the operation speed Must be excluded.
