[0002] A panel socket refers to a seat into which one or more circuit wiring can be inserted. The plug of an electrical appliance can power the appliance after being inserted into the panel socket. However, when using some electrical appliances that need to be moved, such as vacuum cleaners and hair dryers, especially mobile industrial appliances such as cutting machines and angle grinders, the connecting wire of the plug is more likely to fall off after being tightened.

[0003] At present, a Chinese patent with announcement number CN213520582U discloses an anti-dropping power plug and socket, including a plug and a socket. The plug includes a plug panel and a metal insert arranged on the plug panel. A fixing hole is opened on the socket panel, and a positioning spring is arranged in the fixing hole. A positioning piece is also arranged on the plug panel. A limiting bayonet is arranged at one end of the positioning piece close to the plug panel. After the plug is inserted into the socket, the positioning spring is stuck in the limiting bayonet, thereby achieving an anti-dropping effect.

[0004] The above patent still has shortcomings. The above patent is fixed by a limit snap-in at the plug and a positioning spring at the socket. Usually the socket needs to adapt to the plugs of most electrical appliances. The plugs of most electrical appliances cannot cooperate with the above socket to achieve the anti-falling effect, and the applicability is poor. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a panel socket that prevents plugs from falling off, which has the advantage of preventing most electrical appliance plugs from falling off.

DETAILED DESCRIPTION

[0022] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0023] A panel 2 socket for preventing plugs from falling off comprises a bottom box 1 and a panel 2. Three jacks 3 are provided on the panel 2, which are a ground wire jack 3, a live wire jack 3 and a neutral wire jack 3. A copper sheet is provided on the bottom box 1. A safety door assembly 4, a damping assembly 5, a clamping block 6 and a swivel 7 are provided in the panel 2. An inner ring 37 is also provided in the panel 2. Six connecting plates 8 are provided on the inner ring 37. A guide groove 9 is formed between every two connecting plates 8. The guide grooves 9 form a 120° annular array. The clamping block 6 slides in the guide groove 9, and a spiral pattern 10 is provided on the inner end surface of the swivel 7. A spiral groove 11 cooperating with the spiral pattern 10 is provided on the clamping block 6. When the swivel 7 rotates, the clamping block 6 moves along the guide groove 9 and cooperates with the safety door assembly 4 to clamp the plug. An inner circular plate 12 is also provided in the middle of the swivel 7, and the socket 3 is provided on the inner circular plate 12. The inner circular plate 12 is fixed to the connecting plate 8 by screws. The swivel 7 rotates on the outside of the inner circular plate 12. A handle 38 is also installed on the outside of the swivel 7 for easy rotation.

[0024] A damping mounting groove 13 is also provided between the bottom box 1 and the panel 2. The damping assembly 5 includes a spring 2 14 and a damping ring 15. The damping ring 15 is slidably arranged in the damping mounting groove 13. The spring 2 14 is arranged between the damping ring 15 and the panel 2. The damping ring 15 includes an integrally formed hook ring 16 and a mounting plate 17. A ring groove 18 is provided in the middle of the hook ring 16 for the swivel 7 to extend out. The inner ring 37 is fixed to the hook ring 16 by screws, and the inner ring 37 abuts against the back of the swivel 7. The spring 2 14 is sleeved on the outer side of the hook ring 16, one end of which abuts against the mounting plate 17, and the other end abuts against the back of the panel 2. The mounting plate 17 and the damping mounting groove 13 are respectively provided with a convex strip 19 and a groove 20 for limiting their relative rotation. A hook groove 21 is provided in the hook ring 16, and a flange ring 22 cooperating with the hook groove 21 is provided at the tail of the swivel 7.

[0025] When the clamp 6 clamps the plug, when the user suddenly pulls the plug when using the electrical appliance, part of the pulling force will be removed through the spring 2 14, thereby preventing the wires from being damaged by excessive pulling force, thereby protecting the electrical wires. When the plug receives pulling force, the spring 2 14 will be compressed, causing the plug, damping ring 15, swivel 7, and inner circular plate 12 to move outward, and the connection between the plug and the copper sheet will be cut off, causing power outage, thereby reminding the user that the wires of the electrical appliance have been straightened and tightened and cannot be stretched further, thereby reducing damage to the wires in complex environments such as factories and outdoors.

[0026] The trigger assembly 23 is also provided with a copper sheet installation box 24 for installing the copper sheet on the bottom box 1, and a slide groove 25 is provided on the side end of the copper sheet installation box 24. The trigger assembly 23 includes a trigger block 26. The trigger block 26 is also provided with a spiral groove 11 and cooperates with the spiral pattern 10. A pull groove 27 is provided on the hook ring 16. The trigger block 26 is slidably arranged in the slide groove 25. When the swivel 7 locks the plug, the trigger block 26 is inserted into the slide groove 25 and disengaged from the pull groove 27. When the swivel 7 does not lock the plug, the trigger block 26 is inserted into the pull groove 27 to lock the copper sheet installation box 24 and the hook ring 16 together, thereby ensuring that the damping ring 15, the swivel 7 and the inner circular plate 12 will not move outward when the plug is pulled out, thereby increasing the service life of the spring 14.

[0027] By rotating the swivel 7, the spiral pattern 10 and the spiral groove 11 cooperate to drive the clamping block 6 to move toward the plug, and cooperate with the safety door assembly 4 to clamp the plug in the socket 3 to achieve an anti-falling effect. At the same time, through the clamping method, the plugs of most electrical appliances can be clamped, increasing the applicability of the socket. Through the cooperation of the spiral pattern 10 and the spiral groove 11, the swivel 7 has self-locking properties, which increases the fixing strength of the plug.

[0028] During installation, first install the swivel 7 in the hook ring 16 so that the flange ring 22 is stuck in the hook groove 21, and then install the three clamping blocks 6 and the safety door assembly 4 at the selected position, and then fix the mounting plate 17 and the connecting plate 8 to the end face of the hook ring 16, and then install the inner circular plate 12 in the middle of the swivel 7, and fix the connecting plate 8 to the inner circular plate 12 with screws, and finally install the trigger block 26 in the slide groove 25, and combine the bottom box 1 and the panel 2 to complete the installation.

[0029] The safety door assembly 4 includes a block 28 and a spring 29. The block 28 abuts against the three sockets 3 at the same time. The inner circular plate 12 is provided with a first baffle 31 and a second baffle 32. The first baffle 31 abuts against the bottom of the block 28. A spring mounting groove 39 is provided in the middle of the block 28. The spring 29 is arranged in the spring mounting groove 39 and abuts against the second baffle 32, thereby abutting the block 28 against the first baffle 31. The block 28 is also provided with an inclined guide surface 33. The grounding end of the plug is inserted into the plug. When the jack 3 is opened, the inclined guide surface 33 is pressed against and the stopper 28 is moved upward, so that the jack 3 is opened. The stopper 28 includes a neutral baffle 34, a live baffle 35 and a ground baffle 36. The neutral baffle 34 and the live baffle 35 are both inclined. The clamping blocks 6 are respectively arranged at the outer ends of the neutral baffle 34, the live baffle 35 and the ground baffle 36. The neutral baffle 34, the live baffle 35 and the ground baffle 36 cooperate with the clamping block 6 to clamp the socket, and the inclined guide surface 33 is arranged on the ground baffle 36.

[0030] By providing an inclined guide surface 33 on the stopper 28, when the socket is inserted into the jack 3, the stopper 28 is moved upward by the inclined guide plate, thereby opening the jack 3. By arranging the inclined guide surface 33 at the upper end of the ground baffle 36, it is prevented from the user inserting a plug without a ground wire into the socket for use, thereby ensuring the safety of circuit use. By means of the live baffle 35 and the neutral baffle 34, the socket cannot be inserted into the neutral wire and the live wire when the ground baffle 36 is not moved, thereby preventing children from touching the plug while playing and causing electric shock, or inserting foreign objects into the socket to cause short circuits, fires and other electrical accidents.

[0031] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
