Description

Technical Field

[0001] The utility model relates to the technical field of sockets, in particular to a safe self-locking ground socket. Background Art

[0002] Traditional floor sockets usually include an outer frame and an inner frame, and the inner frame is used to cover the socket structure in the outer frame to protect the socket from the influence of the external environment, such as dust, moisture, etc. However, such traditional floor sockets often lack a self-locking function, and the inner frame and the outer frame are simply connected by rotation without an effective locking mechanism.

[0003] In actual use, due to the lack of self-locking function, the inner frame is easily opened accidentally, causing the socket to be exposed, increasing the risk of electric shock and damage. This risk is particularly prominent in public places or places where children can easily reach. In addition, in the long-term use of traditional ground sockets, due to the friction and wear between the inner frame and the outer frame, the inner frame may also loosen or fall off, further increasing the risk of use.

[0004] At the same time, in actual use, the most common problem with open-type floor plugs is that when you put your hand deep into the socket inside the box to get power, you need to use both hands, one hand to hold the lid and the other hand to insert the plug. If you are not careful, the lid can easily fall and injure your arm. Utility Model Content

[0037] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0038] See also Figures 1 to 8 This embodiment discloses a safety self-locking ground socket, which is characterized by comprising:

[0039] An outer frame 10, wherein the outer frame 10 is used to accommodate the inner frame 20;

[0040] An inner frame 20, wherein the inner frame 20 is rotatably connected to the outer frame 10 via a first rotating shaft 11;

[0041] The self-locking device 30 includes a movable part 31, a hook 32, a connecting part 33, a sliding mechanism 34 and an elastic part 35; the movable part 31 is rotatably connected to the inner frame 20, the movable part 31 is rotatably connected to the hook 32 through a second rotating shaft 37, the hook 32 is located on the upper surface of the movable part 31, the second rotating shaft 37 is connected to one end of the connecting part 33, the connecting part 33 rotates with the rotation of the second rotating shaft 37, the sliding mechanism 34 includes a slide rail 341 and a sliding part 342, the slide rail 341 is connected to the movable part 31, the The slide rail 341 is slidably connected to the sliding member 342, and the sliding member 342 is provided with a matching portion corresponding to the connecting member 33, and the matching portion is connected to the other end of the connecting member 33. When the connecting member 33 rotates, it pushes the sliding member 342 to slide on the slide rail 341, and a locking hole adapted to the sliding member 342 is provided on the outer frame 10. The elastic member 35 is connected to the sliding member 342 and is used to reset the sliding member 342. The reset sliding member 342 drives the sliding member 342 to be inserted into the locking hole, so that the inner frame 20 and the outer frame 10 are locked.

[0042] The outer frame 10 has a through hole in the middle thereof adapted to the inner frame 20 , and the outer frame 10 is used to accommodate the inner frame 20 .

[0043] The inner frame 20 is rotatably connected to the outer frame 10 via the first rotating shaft 11. The inner frame 20 is used to cover the through hole of the outer frame 10. The inner frame 20 is used to protect the jacks from being contaminated by dust, water, etc., and also to prevent accidental touches.

[0044] The movable member 31 is connected to the inner frame 20 , and the movable member 31 provides a supporting basis.

[0045] The hook 32 is rotatably connected to the movable member 31 via the second rotating shaft 37. Specifically, the second rotating shaft 37 is fixedly connected to the hook 32, and both ends of the second rotating shaft 37 are placed in the rotating cavity on the movable member 31. By pulling up the hook 32, the second rotating shaft 37 is rotated synchronously.

[0046] The connecting member 33 is vertically arranged, and one end of the connecting member 33 is fixedly connected to the second rotating shaft 37; the connecting member 33 and the second rotating shaft 37 are perpendicularly arranged to each other, and the connecting member 33 moves synchronously with the hook 32; specifically, when the hook 32 flips upward, the connecting member 33 rotates around the second rotating shaft 37 toward the through hole direction of the outer frame 10.

[0047] The sliding mechanism 34 includes: the slide rail 341 and the sliding member 342, the sliding member 342 is slidably disposed on the slide rail 341; the matching portion is disposed on the sliding member 342, and the matching portion and the sliding member 342 slide on the slide rail 341 synchronously. Specifically, one end of the connecting member 33 away from the second rotating shaft 37 is adapted to the matching portion of the sliding mechanism 34, and the connecting member 33 drives the sliding member 342 to slide on the slide rail 341 by driving the matching portion.

[0048] The outer frame 10 is provided with a locking hole, which is located on the side wall of the outer frame 10 opposite to the self-locking device 30, and the locking hole is adapted to the sliding member 342. When the sliding member 342 is placed in the locking hole, the inner frame 20 and the outer frame 10 are in a locked state; when the sliding member 342 is placed outside the locking hole, the inner frame 20 and the outer frame 10 are in an unlocked state.

[0049] The slide rail 341 is disposed in the movable member 31 , and the movable member 31 and the slide rail 341 are relatively stationary.

[0050] The elastic member 35 is connected to the sliding member 342 and is used to reset the sliding member 342 after releasing the hook 32. When resetting, the sliding member 342 moves toward the lock hole until the sliding member 342 is placed in the lock hole, completing the self-locking process.

[0051] In actual use, when the socket needs to be opened, the hook 32 is pulled, and the hook 32 drives the second rotating shaft 37 to rotate, thereby driving the connecting member 33 to rotate. At this time, the hook 32, the second rotating shaft 37 and the connecting member 33 rotate synchronously; the connecting member 33 pushes the matching portion to make the sliding member 342 slide on the sliding rail 341. The sliding action makes the sliding member 342 withdraw from the lock hole of the outer frame 10, thereby releasing the locking state of the inner frame 20 and the outer frame 10.

[0052] When the socket needs to be closed after use, the hook 32 is released, and the elastic member 35 resets the sliding member 342. During the reset process, the sliding member 342 is inserted into the lock hole of the outer frame 10 again, thereby realizing the automatic locking of the inner frame 20 and the outer frame 10.

[0053] Through the arrangement of the hook 32, the connecting member 33 and the sliding mechanism 34, when the hook 32 is pulled, the connecting member 33 and the second rotating shaft 37 move synchronously, thereby driving the sliding member 342 to slide on the slide rail 341, so that the sliding member 342 is released from the lock hole, that is, the outer frame 10 and the inner frame 20 are switched to an unlocked state. The operation process is simple and clear, without complicated steps or tools, which greatly improves the convenience of use.

[0054] See also Figure 5 The matching portion is a matching groove 343 on the sliding member 342 , and the other end of the connecting member 33 extends into the matching groove 343 .

[0055] The matching portion is the matching groove 343 provided on the sliding member 342 . Specifically, the matching groove 343 penetrates the sliding member 342 , and one end of the connecting member 33 away from the second rotating shaft 37 extends into the matching groove 343 .

[0056] When the connecting member 33 drives the sliding member 342 to slide, the connecting member 33 contacts the side wall of the matching groove 343; the rotating connecting member 33 can contact the side wall of the matching groove 343 along the sliding direction of the sliding member 342 to push the sliding member 342 to slide on the slide rail 341.

[0057] See also Figure 5 In order to prevent the connecting member 33 from being bent and damaged, the sliding member 342 can achieve a locking function without pulling the hook when it touches the outer frame 10; the aperture of the matching groove 343 is larger than the width of the connecting member 33.

[0058] The matching groove 343 is used to accommodate the connecting member 33. When the connecting member 33 does not drive the sliding member 342, the connecting member 33 contacts the inner wall of the matching groove 343 away from the lock hole, and there is a gap between the connecting member 33 and the inner wall of the matching groove 343 close to the lock hole. That is, when the sliding member 342 is driven to slide, the connecting member 33 directly drives the sliding member 342 to rotate; when the inner frame 20 and the outer frame 10 need to be closed, the inner frame 20 is pressed down so that the sliding member 342 contacts the outer frame 10, and the outer frame 10 presses the sliding member 342 so that the sliding member 342 slides along the slide rail 341. At this time, the matching groove 343 moves synchronously. Due to the setting of the gap, the sliding member 342 will not be limited by the connecting member 33.

[0059] Specifically, if the mating groove 343 is adapted to the connecting member 33 (i.e., the aperture of the mating groove 343 is equal to the thickness of the connecting member 33), when the connecting member 33 rotates, the connecting member 33 will tilt, and the adapted mating groove 343 will cause the connecting member 33 to bend or the sliding member 342 to be damaged due to the lack of redundant arrangement.

[0060] See also Figure 5 The sliding member 342 is a slider, the sliding rail 341 is provided with a sliding groove, the sliding groove is slidably connected to the sliding member 342, one end of the elastic member 35 is connected to the side wall of the sliding groove, and the other end of the elastic member 35 is connected to the slider, and a locking channel 344 is provided at one end of the sliding groove close to the lock hole, and the locking channel 344 is used for the sliding member 342 to extend.

[0061] The slide groove is a groove on the slide rail 341, and the slide groove is adapted to the slider, and the slider slides on the slide groove; the locking channel 344 is placed on the slide rail 341, and the locking channel 344 is connected to the slide groove, and the locking channel 344 is placed at one end of the slide groove close to the lock hole. It should also be noted that the locking channel 344 is adapted to the slider.

[0062] When the connecting member 33 drives the slider, the end of the slider slides out from the slide groove and the locking channel 344 until the end of the slider is placed in the locking hole, thereby realizing the locking function; or, the end of the slider escapes from the locking hole and is retracted into the slide groove, thereby realizing the unlocking function.

[0063] See also Figure 5 The side wall of the slide groove and the side wall of the elastic member 35 are both provided with a first mounting groove for accommodating the two ends of the elastic member 35, and the elastic member 35 is located at one end of the sliding member 342 away from the locking hole.

[0064] The first mounting grooves are disposed on the two opposite side walls of the slide groove and the slider, and the two ends of the elastic member 35 are respectively connected to one of the first mounting grooves to achieve automatic reset of the slider, thereby achieving reset of the hook 32. Furthermore, the two first mounting grooves are disposed along the sliding direction of the slider.

[0065] The bottom of the slide groove is provided with a second installation groove for accommodating the elastic member 35, and the second installation groove is used to accommodate the elastic member 35 of a larger size. In this embodiment, the elastic member 35 can be a coil spring, a magnetic member, etc.

[0067] The movable member 31 is provided with a cavity for accommodating the sliding mechanism 34 . The sliding rail 341 is placed in the cavity, and the movable member 31 covers the sliding rail 341 .

[0068] The first opening and the second opening are respectively provided on the two opposite side walls of the cavity; the first opening is used for the sliding member 342 to extend, and the end of the sliding member 342 can be placed in the lock hole. The second opening is placed on one side wall of the cavity close to the through hole of the outer frame 10, and the first opening and the second opening are set in the sliding direction.

[0069] The self-locking device 30 is installed in the cavity through the second opening.

[0070] See also Figure 1 , Figure 3 as well as Figure 7 The inner frame 20 is concave-shaped, and the concave-shaped notch of the inner frame 20 accommodates the self-locking device 30. The inner frame 20 is rotatably connected to the self-locking device 30 via a third rotating shaft 39.

When the movable part 31 flips upward, the wire outlet 36 tilts upward, and the external power cord can be plugged into the plug through the wire outlet 36. Specifically, the hook 32 is lifted to drive the movable part 31 to rotate around the third rotating shaft 39, and then the inner frame 20 is driven to rotate around the first rotating shaft 11 to open the inner frame 20; after the power cord is inserted, the inner frame 20 can be covered, and the power supply is still connected through the wire outlet 36. The wire outlet 36 prevents the inner frame 20 from occupying the ground space.
