Description

Positioning means

The invention provides a positioning device, in particular a positioning device which can be conveniently locked or unlocked. The inner limiting rod of the limiting ring body of the two long protruding rods and the two short protruding rods of the driving sleeve body are respectively limited to the card slot. And driving the screwing element is located in the sleeve of the perforation movable lifting displacement, which can be used to rotate the rod side of the rotating rod into and out of the sleeve of the rotating space, to achieve the purpose of easy operation.

According to the general board (board-to-board), when assembling and joining, it is locked by a positioning screw with a knob, a collar and a screw. The screw and the collar are first fixed on the outer panel, and the first rotation is performed. The knob is used to lock the panel of the inner layer to form a preset positioning, and after the screw is locked by the hand tool, the outer panel is locked and integrated with the inner panel, and the locking mode of the multi-layer board is It can be used in working machine or other board-to-board connection; however, these working machines need to use plates for locking, most of them are power devices or rate adjustment devices, and various power devices and rate adjustment devices are located. The inside of the space formed by the implement shell can be assembled, locked and disassembled by means of the sheet metal. When the power unit is broken or damaged, or the rate adjusting device changes or adjusts the rate, the sheet is removed. In order to carry out related maintenance and adjustment work, and the plate is locked by a plurality of positioning screws, it is easy to cause the positioning screws to fall off during the disassembly process. , You can not re-locking plate back into place, the impact of inconvenience and trouble assembling, dismantling operations, namely the industry to solve the lock screw The disadvantage of easy loss is the development of a fixing device consisting of a cap, a screw part and a positioning seat. The positioning seat of the fixing device is first fastened in the perforation of the plate, and then the screw is locked to another plate. The fixing is formed, and when the user removes the plate, the fixing device can still be fixed in the perforation of the plate through the positioning seat without causing the fixing device to fall off or be lost, but the assembly process must still be operated by the user or Hand tools (such as screwdrivers or wrenches) are used to control the locking or dismounting of the fixing device. There are still many problems and problems in practical application.

Moreover, it is applied to the combination of two opposing plates in a locking and fixing manner. Under the demand of modular mass production and processing efficiency, the use of screws for cumbersome manual assembly procedures will seriously affect the progress of the manufacturers. Because the screw is small in size, it is easy to be lost during the process of locking the two plates, and it may be assembled, aligned or locked due to the difference in the screw hole size of the screw locking position or the misalignment of the number of the screw holes and the pitch. Difficulties, and the space for the operating screws between the two plates is quite narrow, that is, the screw is easily assembled and disassembled, which is easily obstructed by surrounding objects, which is not only time-consuming and inconvenient, but also causes overall production. The increase in costs has increased the burden on the industry.
