Description

Rotary shaft device

The present invention provides a rotating shaft device, in particular, a rotating shaft device for axially displaceing the shaft sleeve on the connecting shaft on one side of the shaft seat, and the shaft seat is coupled to the shaft to assemble the shaft sleeve on one side of the base portion for the sleeve When the assembly is slipped at the preset slip channel, the frictional resistance is reduced.

According to many storage cabinets for housing, cabinets or cabinets, there are drawers or sliding seats for the purpose of pulling and pulling, so that various items can be placed or removed. The seat body, etc., both sides use the rotating shaft to slide on the sliding track, so that the drawer or the sliding seat can move into and out of the storage cabinet, and generally the sliding of the drawer or the sliding seat is installed inside the storage cabinet. In the track, the sliding track is screwed to the side wall surface of the storage cabinet by screws, and then the drawer or the sliding seat body is assembled between the two side sliding rails, and the drawer or the sliding seat body is When slipping between the two side sliding rails, frictional resistance is often easily caused to cause the drawing to be unsmooth or the carding is missing, and the use is rather inconvenient and unfavorable for maintenance or replacement.

However, today's computer technology is growing at an ever-changing speed, and the development trend of computers is also moving toward design patterns such as powerful computing functions, fast speed and small size, resulting in communication connections between computer-related peripheral devices and recording media machines (eg, disk drives). The number of hard drives, CD players, burners, etc., is also reduced, and is used for the housing of the computer and the records contained inside it. The fixing or disassembly method between media machines must be simpler and can not occupy too much space, so as to effectively respond to the trend of computer shrinking, and also meet the design requirements of light, thin, short and small electronic products; Therefore, in addition to the cabinets generally used for accommodating articles, many electronic and electrical technology products are used to house electronic components, cabinets or cabinets of consoles or control systems, such as industrial computers, electronic signals or electronic materials. Or telecom chassis, etc., that must consider the stability of the overall system, the convenience of maintenance and replacement, etc., and at the same time, for the user to operate conveniently to reduce the loss of downtime or manpower application, but the media storage device currently used is fixed in storage. When cabinets such as cabinets or telecom cabinets and cabinets are used, even if screw locking is used, the screws must be aligned with the screw holes in the cabinet or the cabinet during assembly, and the operation is locked one by one. The working hours and downtime for maintenance are also greatly increased. If the frame structure of the cabinet or cabinet is thinner and the height is not high. The chassis or the cabinet is covered with interface cards, hard disks, motherboards, and power cables. It also blocks the hand tools from entering the locking or disassembling operation, and often causes the screws to fall off and become lost when locked. The size of the wire does not match the size of the screw hole to be locked, but it is still locked by force. This may cause damage to the screw hole of the chassis or cabinet, which is not suitable for disassembly or assembly work.

As shown in FIG. 9 , it is an exploded perspective view of a positioning device of a media storage device assembled in a conventional chassis or a cabinet. The two side panels A1 of the chassis A are respectively provided with a plurality of through holes A11 and are respectively arranged on the side plates A1. A positioning device B is disposed, and the positioning device B is provided with a long strip B1, and a through hole B11 is respectively disposed in the center of each slider B1 for the positioning screw C to pass through and then lock into each side plate A1. In the perforation A11, a rail groove B2 is formed on each of the two sides of the slider B1, and a pressing arm B3 is disposed on the back surface of each of the rails B2, and a latch B31 is protruded on the inner side of each pressing arm B3 of the positioning device B. Can be worn correspondingly on each side panel A1 At the hole A11, the slider B4 is respectively wrapped around the outside of each of the pressing arms B3, and can be slid along the respective rail grooves B2, so that the elastic displacement can be generated by moving the pressing arms B3 while moving the respective sliders B4. The latching hole B1 is inserted into the holding hole D1 of the media storage device D of the chassis A located between the two side panels A1, or the media storage device D can be quickly disassembled to form a separation. However, when the positioning device B is actually applied, the user must first move. After the unlocking state is released on the slider B4, and the media storage device D is laterally placed between the two side panels A1 of the chassis A, the slider B4 is pushed and forced to interlock the pressing arm B3 to perform the media storage device D. The locking action is complicated in the overall operation and cannot be quickly replaced. It is also impossible to clearly see from the outside of the positioning device B whether the pin B31 of the pressing arm B3 is aligned with the fixing hole D1 of the media storage device D, resulting in alignment assembly. The trouble and inconvenience increase, and the structure tends to be complicated due to the large number of components of the positioning device B. It is not only necessary to open a plurality of sets of molds and increase the assembly process, but also greatly increases the production cost and is not conducive to product modularization. Resulting in the loss of reducing capacity and so on.

Therefore, how to solve the problems and problems that are difficult to assemble or disassemble when installing related mechanisms in the various types of chassis or cabinets, and the complicated structure, unfavorable assembly, and high cost of the applied mechanism components are complicated and inconvenient.
