Description

Technical Field

[0001] The utility model relates to the technical field of socket strip equipment, in particular to a socket strip with sealing and dustproof functions. Background Art

[0002] A power strip, also known as a power strip, extension cord assembly, or extension cord socket, is a removable, multi-outlet socket with power cords and plugs. A power strip is a power distribution device that integrates multiple outlets. Connected to a power outlet via one or more power cords, it allows users to connect multiple electrical devices, saving space and simplifying power wiring. The primary function of a power strip is to provide multiple power outlets, allowing users to power multiple devices simultaneously. Some smart power strips also offer additional features such as timing, energy saving, and overload protection.

[0003] After searching, the Chinese patent application number is: CN202110712298.9, which discloses a power strip to solve the problems that two adjacent sockets on the power strip are sometimes unable to be used at the same time due to space limitations, the cables of electrical appliances connected from different directions are easily bent, and long-term use may cause cable breakage. The present invention includes an axis and a plurality of socket units arranged on the axis that can rotate independently; each socket unit includes a plug plate and a shell, wherein the shell is rotatably mounted on the axis, and the plug plate is rotatably mounted on the shell; the plug plate of each socket unit is provided with a socket for plugging in a plug. The invention can realize the rotation of the plug plate and the rotation of each socket unit, which not only avoids the problem of bending during the plugging process of electrical appliances, but also solves the problem that two adjacent sockets on the power strip are limited in space and cannot be used at the same time.

The second upper socket 10 corresponds to the second lower socket, and each of the second upper socket 10 and the second lower socket 14 is provided with two groups, both of which are beveled, and the specifications of the flat and beveled edges are the same.

[0034] It also includes a blocking structure provided on the socket 12 for blocking the plug-in structure; the blocking structure includes a first baffle 16 and a second baffle 18 provided on the socket 12, the first baffle 16 and the second baffle 18 are both supported by a compression spring 24, and a blocking block 19 is provided on the first baffle 16 and the second baffle 18, and the blocking block 19 corresponds one-to-one to the socket in the plug-in structure.

[0035] The first baffle 16 is U-shaped, and the second baffle 18 is key-shaped. Circular grooves are provided on both sides of the bottom of the first baffle 16 and the bottom of the second baffle 18. A positioning key 20 is provided inside the circular groove. The positioning key 20 is cross-shaped and is used to locate the upper end of the compression spring 24. A spring groove 23 is provided on the power strip 12. The lower end of the compression spring 24 is located within the spring groove 23, and the compression spring 24 can slide within the spring groove 23. Blocks 19 are symmetrically arranged on the two arms of the first baffle 16 and correspond to the first upper socket 9. Blocks 19 are arranged on both sides of the key-shaped body of the second baffle 18 and correspond to the second upper socket 10. Blocks 19 are arranged at the key-shaped end of the second baffle 18 and correspond to the first upper socket 9. The cross-section of the block 19 is designed to be an isosceles trapezoid. One arm of the first baffle 16 is located on one side of the block 19 and is provided with a side socket 17. The second baffle 18 is also provided on one side of one of the blocks 19.

[0040] The socket 12 is mounted on the base 1 by fixing screws. A through hole for the fixing screw is provided on the edge of the socket 12. The base 1 is provided with a threaded hole corresponding to the through hole. The fixing screw passes through the through hole on the socket 12 and is threadedly installed inside the threaded hole on the base 1, thereby realizing the installation between the socket 12 and the base 1.

[0041] Among them, a first hanging ear 5 is provided at one end of the shell 2 on one side of the wiring harness hole 4, and a second hanging ear 6 is provided at the other end of the shell 2.
