All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, fig. 6, fig. 8 and fig. 9, the fully enclosed safety socket rail of the invention comprises a rail, a socket adapter and an electric brush, wherein a lock core is centrally installed at the bottom of the socket adapter; the guide rail 1 is hollow, a first lock hole 1-6 and a packaging opening 1-2 are respectively formed in the center of the front surface and the back surface of the guide rail 1, a lock shell 3 is not transversely inserted into a cavity in the guide rail 1, a second lock hole 3-1 formed in the upper end surface and the lower end surface of the lock shell 3 is vertically aligned with the first lock hole 1-6, a retainer 2 is clamped inside the lock shell 3, an electric brush 4 is installed in a spring groove 2-4 of the retainer 2, the electric brush 4 is selectively contacted with a lock cylinder 8, the lock cylinder 8 is vertically inserted into the first lock hole 1-6 and the second lock hole 2-3 in the centers of the guide rail 1 and the lock shell 3, a safety door 12 is installed in the first lock hole 1-6 and the second lock hole 2-3, a second spring 14 is installed in a second spring groove 13 at the bottom of the safety door 12, and the second spring 14 is in pushing contact with a sealing, the sealing plate 15 is hermetically installed at the bottom notch of the guide rail 1. Wherein, the staff inserts the lock core 8 at the bottom of the socket 7 into the lock case 3 by aligning the safety door 1, and simultaneously clamps the retainer 2 in the middle vacant space of the lock case 3, and simultaneously fixes the retainer 2 in the guide rail 1 by using bolts, so that the lock case 3 rotates. After the installation is completed, the sealing plate 15 can seal the packaging opening on the back of the guide rail 1, so that the invasion of impurities and moisture is avoided. The operation steps are as follows: the socket adapter 7 is rotated to control the lock cylinder 8 to reach a locking state; meanwhile, the electric brush 4 is held in place to be further electrified, so that the control socket is fixed at a daily electrified position. When the socket is not used, the worker can choose to power off the lock cylinder 8 in the following manner. The lock cylinder 7 and the holder 2 rotate together to the unlocking position, and the brush 4 retracts into the lock case to stand by. The lock cylinder 7 can now be withdrawn.

As shown in fig. 2, 4 and 5, the upper and lower ends of the brush 4 are vertically welded with guide posts 4-1, the guide posts 4-1 extend into guide chutes 3-2 formed on the upper and lower end surfaces of the lock case 3, the inner walls of the guide chutes 3-2 are respectively provided with rotation notches 11, and the rotation notches 11 are selectively positioned and embedded with the guide posts 4-1. In order to control the electric brush 4 to complete the selective embracing action with the lock cylinder 7 in the lock shell 3 in a fixed radian, guide posts 4-1 are vertically welded at the upper end and the lower end of the electric brush 4, and the guide posts 4-1 can perform regular selective embracing action along house type slide ways 3-2 arranged on the upper end surface and the lower end surface of the lock shell 3.

The operation is as follows:

(1) when the gear lock shell 3 is at the 0-degree position, the safety door 12 is in a state of resetting and closing the lock hole, and at the moment, the electrified electric brush 4 is retracted in the spring groove 2-4 formed between the lock shell 3 and the retainer 2.

(2) When the lock core 8 at the bottom of the socket adapter 7 is aligned with the guide rail 1, the safety door 12 is pushed open and inserted into the second lock hole 3-1 of the lock case 4. The safety door 12 moves downward and stops under the back pressure of the first spring 5. At the moment, the groove between the lock cylinder 8 and the socket adapter 7 is aligned with the groove at the edge of the lock hole, and the lock cylinder 8 can drive the lock shell 3 to rotate for 90 degrees; when the lock shell rotates, the guide chute 3-2 on the lock shell 3 interacts with the retainer 2, so that the centers of the two electric brush boxes are forced to move rapidly, and the conductive ends of the positive electrode and the negative electrode on the two sides of the lock core 8 are embraced at the same time, so that the electrification is completed.

(3) When the lock shell 3 retracts to 45 degrees, the lock shell drives the electric brush 4, meanwhile, the guide post 4-1 at the top of the electric brush 4 is forced to enter the rotating notch 11 at the 45 degrees, and under the pushing action of the first spring 5, the electric brush 4 is fixed. At this time, the socket adapter 7 is fixed to the guide rail 1; however, the energized area of the brush 4 adheres to the insulating spacer 10, and thus the standby state of the power-off is completed. So as to be used by electrifying at any time and avoid the occurrence of missing condition of the socket adapter 7.

(4) When the lock case 3 is rotated to 0 °, the power-off state can be maintained as in the insertion state, and the lock hole can be closed to eject the socket adapter 7.

As shown in fig. 4, 5, 6 and 7, the front end surface and the rear end surface of the electric brush 4 are respectively provided with a concave port 4-2 and a spring groove 4-3, and the concave port 4-2 is selectively contacted with the lock cylinder 8 to be selectively clasped and butted. The electric brush 4 is selectively contacted with the lock core 8 by a concave port 4-2 matched with the electrifying port of the lock core 8 in shape, and is selectively and embracingly butted.

As shown in fig. 3, 5 and 7, a spring 5 is clamped in the spring groove 4-3, and the spring 5 is in pushing contact with the groove bottom of the retainer 2, which is provided with the spring groove 2-4 at the center. Meanwhile, in order to place a spring arranged on the electric brush 4, a spring groove 4-3 is formed in the back surface of the electric brush 4. The head part of the spring 5 is placed in the spring groove 2-4, and the tail part of the spring 5 is in pushing contact with the groove bottom of the retainer 2 with the spring groove 2-4 arranged in the center.

As shown in fig. 2 and 6, two groups of retainers 2 are butted by taking a lock cylinder 8 as a center, a chamfer 2-2 is arranged on a spring groove 2-4 at the center of the retainer 2, and the size of the opening of the chamfer 2-2 is matched with the appearance of the lock cylinder 8. In order to ensure that the retainer 2 can be attached to the lock cylinder 8 in the rotating process, a chamfer 2-2 is formed in a spring groove 2-4 in the center of the retainer 2, and the size of an opening of the chamfer 2-2 is matched with the shape of the lock cylinder 8.

As shown in fig. 1 and 3, the holder 2 is provided with a second screw hole 2-3, and the second screw hole 2-3 is locked and linked with a first screw hole 1-3 provided on the bottom surface of the guide rail 1 through a bolt. Wherein, in order to fix the retainer 2 in the guide rail 1, an operator can align the bolts with the second screw holes 2-3 and the first screw holes 1-3 to fix the retainer 2 on the inner wall of the guide rail 1.

As shown in fig. 7 and 8, the socket adapter 7 is in pushing contact with the top plane of the security door 12 through the key cylinder 8. The socket adapter 7 manually pushes the lock cylinder 8 against the safety door 12 until the lock cylinder extends into the second lock hole 3-1 in the middle section of the lock shell 3, and then the socket adapter 7 is rotated to control the power-on contact state of the lock cylinder 8 and the electric brush 4.

As shown in fig. 1, the front side of the guide rail 1 is provided with chamfered edges 1-4. Wherein, the chamfered edges 1-4 can prevent the guide rail 1 from slipping out or dust and impurities from entering.

As shown in fig. 9, the two groups of second lock holes 3-1 of the lock case 3 are fixedly connected through a thermoplastic insulating partition plate 10, a flange 9 is thermoplastic formed on the edge of the second lock hole 3-1 with the top facing upwards, and the flange 9 is in clearance fit with the lock cylinder 8. The lock shell 3 can complete synchronous rotation through transmission of the lock cylinder 8, and in the rotation process, the electric brush 8 is in a fixed direction in the retainer 2, so that along with rotation of the lock shell 3, the insulating partition plate 10 in the middle section of the lock shell 3 can be in passive selective contact with the electric brush, current is cut off, and the effect of current protection is achieved.
