Description

Technical Field

[0001] This utility model relates to the field of socket technology, specifically to a locking device for a socket. Background Technology

[0002] During use, three-prong plugs often become loose due to accidental factors. This can lead to sudden power outages when appliances are in use, posing a safety hazard.

[0003] The utility model disclosed in CN105449457A is an anti-loosening socket, including a socket body and a locking device; the locking device includes a first locking movable part, a first locking fixed part, a second locking movable part, and a second locking fixed part; the first locking fixed part is fixed to the upper side of the socket body; the first locking movable part is used to connect the movable end of the first locking fixed part to the first locking fixed part.

[0004] The aforementioned application document states that the plug is locked by a locking device, and the plug wire passes through the gap between the first locking movable parts. During use, people around may collide with it, which may cause the first locking movable parts to loosen and affect the locking effect. Utility Model Content

[0005] This utility model proposes a locking device for a socket.

[0006] The technical solution of this utility model is as follows: A locking device for a socket includes a socket panel, a socket hole at the front end of the socket panel, a locking mechanism at the front end of the socket panel, and a slowing mechanism at the top and bottom of the socket panel; the locking mechanism includes two sets of locking rods, both ends of which are fixedly connected to a rotating column, and a torsion spring rod A is provided at the end of the rotating column away from the locking rod, the rotating column being rotatably connected to the socket panel through the torsion spring rod A; a fixing block is fixedly connected to the surface of one set of locking rods, and a locking block is fixedly connected to the surface of the other set of locking rods; a plug plate is slidably connected inside the fixing block, a push plate is fixedly connected to the side of the plug plate, a return spring is fixedly connected to the side of the push plate near the fixing block, slots are provided at the top and bottom of the plug plate, and grooves are provided at the top and bottom of the locking block, a telescopic spring is provided inside the groove, an arc-shaped block is slidably connected inside the groove through the telescopic spring, and a pull rod is fixedly connected to the end of the arc-shaped block near the telescopic spring.

[0007] The locking rod is C-shaped, and the torsion spring on the torsion spring rod A is initially compressed. When the torsion spring on the torsion spring rod A rebounds, it will cause the locking rod to rotate to the side of the socket panel.

[0008] The end of the reset spring away from the push plate abuts against the fixed block, and the end of the insert plate away from the push plate is located inside the lock block. When the reset spring rebounds, it will drive the insert plate to move to the left and leave the lock block.

[0009] The opening size of the slot is equal to the opening size of the groove, and half of the arc-shaped block is initially located inside the slot. When the arc-shaped block is stuck in the slot, the insert plate cannot leave the interior of the lock block.

[0010] The arc surface of the arc block faces the direction of the fixed block, and the longitudinal depth of the groove is greater than the longitudinal length of the arc block. When the arc surface of the arc block is squeezed, it will move into the groove, and the arc block can be completely retracted into the groove.

[0011] The deceleration mechanism includes a torsion spring rod B, a deceleration block, and a limiting rod. The torsion spring rod B is rotatably connected to the socket panel, and a contact plate is fixedly connected to the surface of the torsion spring rod B. The deceleration block is fixedly connected to the surface of the rotating column, and the limiting rod is fixedly connected to the socket panel.

[0012] The end of the contact plate away from the torsion spring rod B is arc-shaped, and the end of the contact plate away from the torsion spring rod B is close to the surface of the rotating column. When the rotating column rotates, the deceleration block on its surface will contact the contact plate.

[0013] The limiting rod is close to the contact plate, and the deceleration block is hemispherical in shape. When the hemispherical rubber deceleration block is squeezed against the contact plate, it will generate a large resistance.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] 1. This utility model is equipped with a locking mechanism, which can fix the three-prong plug by two sets of locking rods to prevent it from loosening and falling off. The cooperation of components such as the plug plate, locking block, and arc block will prevent the two sets of locking rods from accidentally separating. When separation is required, pull the top and bottom rods of the locking block at the same time, and the two sets of locking rods will automatically flip to both sides of the socket panel.

[0016] 2. This utility model has a slowing mechanism, which slows down the locking rod when it flips to the side of the socket panel due to the rebound of the torsion spring on the torsion spring rod A. The contact plate, deceleration block, and limiting rod work together to prevent the locking rod from flipping to the side of the socket panel with excessive force and causing damage to the wall behind the socket panel.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] like Figures 1-5As shown, this embodiment proposes a locking device for a socket, including a socket panel 1. The socket panel 1 has a socket hole 2 at its front end and a locking mechanism 3 at its front end. Both the top and bottom of the socket panel 1 are provided with slowing mechanisms 4. The locking mechanism 3 includes two sets of locking rods 31, with rotating posts 32 fixedly connected to both ends of each set of locking rods 31. A torsion spring rod A33 is provided at the end of the rotating post 32 away from the locking rods 31. The rotating post 32 is rotatably connected to the socket panel 1 via the torsion spring rod A33. The locking rods 31 are generally C-shaped. The torsion spring on the torsion spring rod A33 is initially compressed. When the torsion spring on the torsion spring rod A33 rebounds, it will cause the locking rod 31 to rotate to the side of the socket panel 1. A fixing block 34 is fixedly connected to the surface of one set of locking rods 31, and a locking block 313 is fixedly connected to the surface of the other set of locking rods 31. A plug plate 35 is slidably connected inside the fixing block 34. A push plate 36 is fixedly connected to the side of the plug plate 35. A return spring 37 is fixedly connected to the side of the push plate 36 near the fixing block 34. The return spring 37 is located away from the push plate 36. The end of the insert plate 35 abuts against the fixed block 34. The end of the insert plate 35 away from the push plate 36 is located inside the locking block 313. When the return spring 37 rebounds, it will drive the insert plate 35 to move to the left and leave the interior of the locking block 313. The top and bottom of the insert plate 35 are provided with slots 38. The top and bottom of the interior of the locking block 313 are provided with grooves 39. The inside of the grooves 39 is provided with telescopic springs 310. The inside of the grooves 39 is slidably connected to the arc-shaped block 311 through the telescopic springs 310. The opening size of the slots 38 is equal to the opening size of the grooves 39. In the initial state, half of the arc-shaped block 311 is located inside the slot 38. When the arc-shaped block 311 is stuck in the slot 38, the insert plate 35 cannot leave the interior of the locking block 313. The arc surface of the arc-shaped block 311 faces the direction of the fixed block 34. The longitudinal depth of the groove 39 is greater than the longitudinal length of the arc-shaped block 311. When the arc surface of the arc-shaped block 311 is squeezed, it will move into the groove 39. The arc-shaped block 311 can be completely retracted into the groove 39. A pull rod 312 is fixedly connected to the end of the arc-shaped block 311 near the telescopic spring 310.

[0028] In this embodiment, two sets of locking rods 31 are used to limit and fix the triangular plug to prevent it from falling off. When it is necessary to separate the two sets of locking rods 31, the top and bottom pull rods 312 of the locking block 313 are pulled simultaneously, thereby causing the arc-shaped block 311 to move away from the slot 38 and retract into the groove 39. At this time, the return spring 37 rebounds and causes the plug plate 35 to move away from the inside of the locking block 313. The fixing block 34 separates from the locking block 313, and the torsion spring on the torsion spring rod A33 rebounds and causes the locking rod 31 to rotate to the side of the socket panel 1. At this time, the triangular plug can be pulled out. When the three-prong plug is reinserted, the two sets of locking rods 31 are rotated back to the front end. The push plate 36 pushes the insert plate 35 to the right and inserts it into the locking block 313. At this time, the arc surface of the arc block 311 is squeezed and retracts into the groove 39. The telescopic spring 310 is compressed. When the groove 39 coincides with the slot 38, the telescopic spring 310 rebounds and drives the arc block 311 into the slot 38. At this time, the insert plate 35 cannot leave the inside of the locking block 313, thus preventing accidental contact that could cause the two sets of locking rods 31 to separate.

[0029] Example 2

[0030] like Figures 1-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a deceleration mechanism 4, including a torsion spring rod B41, a deceleration block 43, and a limiting rod 44. The torsion spring rod B41 is rotatably connected to the socket panel 1, and a contact plate 42 is fixedly connected to the surface of the torsion spring rod B41. The deceleration block 43 is fixedly connected to the surface of the rotating column 32, and the limiting rod 44 is fixedly connected to the socket panel 1. The end of the contact plate 42 away from the torsion spring rod B41 is arc-shaped, and the end of the contact plate 42 away from the torsion spring rod B41 is close to the surface of the rotating column 32. When the rotating column 32 rotates, the deceleration block 43 on its surface will contact the contact plate 42, and the limiting rod 44 is close to the contact plate 42. The deceleration block 43 is hemispherical in shape. When the hemispherical rubber deceleration block 43 is squeezed with the contact plate 42, it will generate a large resistance.

[0031] In this embodiment, when the torsion spring on the torsion spring rod A33 causes the two sets of locking rods 31 to flip to both sides of the socket panel 1, the rotation of the rotating column 32 will drive the deceleration block 43 to contact the contact plate 42. At this time, the contact plate 42 cannot rotate under the restriction of the limiting rod 44, and the deceleration block 43 will squeeze the contact plate 42 to generate greater resistance, thereby slowing down the speed of the locking rod 31 flipping to the side of the socket panel 1 and preventing damage to the wall behind the socket panel 1. When the locking rod 31 is flipped to the front end, the deceleration block 43 contacts the contact plate 42 again. At this time, the contact plate 42 will rotate and will not squeeze the deceleration block 43 too much. The resistance is small during this process.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
