Description

Rotational positioning device

The present invention provides a rotational positioning device, in particular a positioning device that uses a rotational pressing method to lock or unlock. A fixed seat and a rotation unit are assembled above the base, so that the rotation unit is located on the fixed seat and rotated and pressed to drive the two positioning bodies to form a stopper on the base to form a locking or retreat, so as to facilitate the driving of the positioning device to lock or automatically reset and unlock.

Generally, when assembling and joining plates (plate to plate), they are locked by positioning screws with knobs, collars and screws. The screws and collars are first fixed on the outer panel, and the knobs are first rotated to allow the screws to lock into the inner panel to form a preset position. After the screws are tightened with hand tools, the outer panel and the inner panel are locked into one. This locking mode of multi-layer plates can be used in machine tools or other plate Plates are used for plate connection; however, the parts where these machine tools need to use plates for locking are mostly power devices or speed adjustment devices, and various power devices and speed adjustment devices are located inside the space formed by the machine shell, that is, the plates can be assembled, locked, and disassembled. When the power device crashes, fails, or is damaged, or the speed adjustment device changes or adjusts the speed, the plates can be removed for operation. The plate is locked by multiple positioning screws, so it is easy to cause the positioning screws to fall off or be lost during the disassembly process, and the plate cannot be locked back to its original position, affecting the inconvenience and trouble of assembly and disassembly. In order to solve the problem of easy loss of locking screws, some industry insiders have developed a fixing device composed of a nut, a screw rod and a positioning seat. The positioning seat of the fixing device is first buckled on the plate. The fixing device is fixed in the through hole of the plate and then locked to another plate by the screw. When the user removes the plate, the fixing device can still be fixed in the through hole of the plate through the positioning seat, so that the fixing device will not fall off or be lost. However, during the assembly process, the user must still apply force or use hand tools (such as screwdrivers or wrenches) to control the locking or disassembly of the fixing device. There are still many deficiencies and troubles in actual application.

Furthermore, the application of locking and fixing two opposing plates together, under the current emphasis on modular mass production and processing efficiency, requires the use of screws for cumbersome manual assembly procedures, which will seriously affect the manufacturer's delivery progress. In addition, due to the small size of the screws, they are easy to be lost in the process of locking the two plates. In addition, due to the difference in the size of the screw holes at the screw locking position or the inconsistency of the number of screw holes and the pitch, it will cause difficulties in assembly, alignment or locking. In addition, the space between the two opposing plates for operating the screws is quite narrow, that is, the screws are easily blocked by surrounding objects during assembly and disassembly. Not only is it very time-consuming and inconvenient, it will also lead to an increase in overall production costs, resulting in an increase in the burden on the industry.

In addition, currently, various electronic device chassis or servers are equipped with multiple removable hard disks (such as SSDs or HDDs). Usually, various hard disks are pushed into the chassis or servers by sliding to form an electrical connection for storing or reading data. However, after the hard disks are pushed into the chassis or servers, they are only connected to each other through electrical connectors. It is difficult to align and assemble them due to offset and tolerance, and there are no other positioning devices or The fixing mechanism cannot form a guiding alignment function, which can easily cause the hard disk and the chassis or server to loosen or separate. Especially when the chassis or server is shaken or swayed by external forces, it is also easy to cause the hard disk and the chassis or server to fall off or separate, which can easily cause instantaneous communication interruption between the hard disk and the chassis or server, affecting the electrical connection between the hard disk and the chassis or server, shortening the service life, etc.

Therefore, how to solve the problem and trouble of the fixing device currently used for locking the plate being easily loosened or disengaged due to being rotated by mistake, and the trouble and inconvenience of applying force or using hand tools when assembling the fixing device are the directions that the relevant manufacturers in this industry are eager to study and improve.
