Detailed Description

As shown in fig. 1 to 3, a rail holder assembled in an electronic device, such as a power supply, a microcomputer, a router or a Hub (Hub), is disclosed, which is a molded object formed by injection molding an insulating material, such as plastic, and thus, the rail holder includes a body 1 and a movable fixing member 2.

The body 1 is a geometric, e.g. rectangular, sheet, and the body 1 is provided with at least one through hole 11. As shown in fig. 6 and 7, after a connecting member 3, such as a screw, is inserted through each through hole 11, and is locked in a locking hole 41 correspondingly formed on the back surface of the electronic device 4, the rail holder is fixed on the back surface of the electronic device 4.

Furthermore, the back of the main body 1 is provided with a fastening groove 12, and an upper edge of the fastening groove 12 protrudes downward to form an upper retaining edge 121. As shown in fig. 3, the inner side of the upper retaining edge 121 has an upper guiding surface 122, and an upper fastening groove 123 is formed between the upper retaining edge 121 and the fastening groove 11.

In addition, a pair of elastic supporting structures 13 are disposed at two sides of the fastening slot 12 at an interval, each elastic supporting structure 13 includes an elastic supporting piece 131 and a piece slot 132 adjacent to the elastic supporting piece 131, and the piece slot 132 is used to provide a deformation space for the elastic supporting piece 131, so that when an upper insertion piece 51 of a guide rail 5 (shown in fig. 8 to 15) is inserted into the upper fastening slot 123, the pair of elastic supporting pieces 131 can elastically abut against the upper insertion piece 51 to increase the stability after insertion, without shaking.

Furthermore, the lower edge of the fastening groove 12 is connected to an accommodating space 14, a pair of rail grooves 141 of a sliding rail mechanism is disposed on two sides of the accommodating space 14, and each rail groove 141 is connected to an anti-falling groove 142, so as to prevent the movable fastening member 2 from falling out of the accommodating space 14.

In particular, the accommodating space 14 is further provided with an elastic expansion mechanism, which includes a fixing tenon 143 extending upward from the center of the bottom edge of the accommodating space 14 and having an arc-shaped head 144 at the top.

The movable fixing member 2 is a hollow rectangular sheet body, and includes a pair of protruding rails 21 corresponding to the sliding rail mechanism, the pair of protruding rails 21 are sleeved in the pair of rail grooves 141, and each protruding rail 21 is provided with a stop hook 211 buckled into the corresponding anti-drop groove 142, so as to prevent the movable fixing member 2 from dropping out of the accommodating space 14.

Furthermore, a buckle tooth 22 is disposed on the top of the movable fixing member 2, a lower guide surface 221 is disposed on the outer side of the buckle tooth 22, and a lower buckle slot 222 is formed between the buckle tooth 22 and the buckle slot 11. The lower catch 222 provides for insertion and support of a lower blade 52 of the rail 5 (shown in fig. 8-15).

In addition, the movable fastening member 2 is provided with a hollow groove 23 corresponding to the elastic expansion mechanism, and a mortise 231 for the fixed tenon 143 to pass through is provided at a position corresponding to the fixed tenon 143, the arc-shaped head 144 corresponding to the elastic expansion mechanism extends out of a pair of arc-shaped elastic pieces 232 arranged in a mirror image manner, and free ends of the pair of arc-shaped elastic pieces 232 contact with two sides of the arc-shaped head 144, so that the movable fastening member 2 has a constant extension function relative to the buckling groove 12, and forms a locking and buckling function.

Referring to fig. 2 again, the movable fixing member 2 is installed in the accommodating space 14 of the main body 1 by the sliding rail mechanism therebetween according to the above description, and the buckle teeth 22 of the movable fixing member 2 can constantly protrude into the buckle groove 12 by the elastic action of the elastic telescopic mechanism therebetween, so as to form the locking and buckling functions. As can be clearly seen from fig. 4, each of the retaining hooks 211 can move in the corresponding anti-slip groove 142 to prevent the movable fastening member 2 from slipping out of the accommodating space 14, and to define a limit for the movable fastening member 2 to move upwards elastically.

As shown in fig. 5, when the movable fastening member 2 is pressed by an external force, the pair of arc-shaped resilient pieces 232 move downward along the two sides of the arc-shaped head portion 144 and move the latch 22 downward to the bottom edge of the latching groove 12 to perform the unlocking and separating functions.

Fig. 6 and 7 are schematic views showing the rail holder assembled in an electronic device, such as a power supply. During assembly, a connecting member 3, such as a screw, is inserted through each through hole 11 of the rail holder and is locked in a locking hole 41 correspondingly formed in the back of the electronic device 4, thereby completing the assembly of the rail holder and the electronic device 4.

As shown in fig. 8 to 12, to hang an electronic device 4 on a guide rail 5 (shown in fig. 8), a user first holds the electronic device 4 and tilts forward at an angle and moves downward (shown in fig. 9), so that the upper guide surface 122 of the upper retaining edge 121 contacts an upper insertion piece 51 of the guide rail 5, and the upper insertion piece 51 is guided into the upper buckling groove 123 along the upper guide surface 122, and the pair of elastic supporting pieces 131 can elastically abut against the upper insertion piece 51 to increase the stability after plugging (shown in fig. 10).

Next, the bottom of the electronic device 4 is moved toward a lower insert 51 of the guide rail 5, so that the lower guide surface 221 of the tooth 22 contacts the lower insert 52 (shown in fig. 11). Finally, the bottom of the electronic device 4 is pushed back, so that the lower insertion piece 52 moves along the lower guide surface 221, and the guide rail holder is urged to move down elastically, so that after the lower insertion piece 52 is guided into the lower fastening groove 222, the movable fastening member 2 moves up elastically, so as to provide a support function for the lower insertion piece 52, and the fastening teeth 22 can protrude into the fastening grooves 12 constantly, so as to complete the locking and fastening functions for the guide rail 5 (shown in fig. 12).

As shown in fig. 13 to 15, to separate the electronic device 4 from the guide rail 5, a user holds the electronic device 4 and moves upward to press the lower insert 52 against the movable fixing member 2 and urge the movable fixing member 2 to move downward elastically, while the latch 22 retracts to the bottom edge of the latching slot 12 to separate the upper insert 51 from the upper latching slot 123 (shown in fig. 13). Then, the upper portion of the electronic device 4 is rotated to completely disengage the upper insert 51 from the upper stop edge 121, and the movable fixing member 2 is still in the elastic compression state (shown in fig. 14).

Finally, the electronic device 4 is moved downward, so that the rail holder is completely separated from the rail 5, and the movable fixing member 2 is in an elastically extended state, so as to complete the unlocking and separating functions of the rail 5 (shown in fig. 15).

Therefore, through the implementation of the present invention, the effect is that the rail fixing device does not need to additionally add a pull handle or equivalent capable of pulling the movable fixing member, and only needs to grip the electronic device and perform the actions of pushing up, rotating forward, moving down, and the like, so as to complete the actions of unlocking and separating the rail. When the electronic device is to be fastened to the guide rail, the electronic device is held in the same way, and the electronic device is tilted forwards by an angle and moves downwards, rotates forwards, pushes backwards and the like, so that the locking and fastening actions of the guide rail can be completed, and the electronic device is a preferable structure which is not seen in the prior art of similar articles.

The present invention is disclosed in the preferred embodiments, and all changes and modifications derived from the technical ideas of the present invention and easily inferred by those skilled in the art are included in the scope of the claims of the present invention.
