Description

Technical Field

[0001] The utility model relates to the technical field of sockets, in particular to a waterproof ground socket with adjustable height. 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 color of the inner frame of the ground plug is different from the ground material, which affects the overall appearance. In addition, the existing ground plug has weak waterproof performance. When water penetrates into the ground plug, it is easy to cause dangers such as short circuits.

[0005] Furthermore, during the installation process, due to the uneven bottom of the reserved pit or the uneven ground, the ground socket cannot be installed or there is a height difference between the upper surface of the socket and the ground after installation, which not only affects the appearance but also causes harm to the user.

[0068] The movable member 31 is rotatably connected to the inner frame 20 to achieve a flip-up function, and the movable member 31 provides a supporting basis.

[0069] In this embodiment, a hole for accommodating the hook 32 is disposed in the middle of the cover plate 37 , and a cover plate is further disposed on the movable member 31 , and the upper surface of the cover plate 37 is flush with the hook and the ground.

[0070] The hook 32 is rotatably connected to the movable member 31 via the second rotating shaft 36. Specifically, the second rotating shaft 36 is fixedly connected to the hook 32, and both ends of the second rotating shaft 36 are placed in the rotating cavity on the movable member 31. By pulling up the hook 32, the second rotating shaft 36 is rotated synchronously.

[0071] The connecting member 33 is vertically arranged, and one end of the connecting member 33 is fixedly connected to the second rotating shaft 36; the connecting member 33 and the second rotating shaft 36 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 36 toward the through hole direction of the outer frame 10.
