Abstract
Description
Technical Field
[0001] This utility model belongs to the field of power supply equipment technology, and more specifically, it relates to a novel expandable power strip. Background Technology
[0002] A power strip is a multi-outlet socket with a cord, also known as a power strip or extension cord. Its technical name is cord extension assembly or extension cord socket. It is typically made of materials such as bakelite, ceramic, or plastic, and has multiple sockets to connect multiple power plugs simultaneously, saving space and wiring. Power strips are mainly used to connect electrical appliances to the power supply, providing multiple power interfaces for convenient simultaneous power supply to multiple devices. Traditional power strips are usually made of metal and plastic, often rectangular or round in shape, and equipped with a switch to control the power supply. Modern power strips incorporate intelligent design, adjusting power output according to the power requirements of electrical appliances to improve energy efficiency, and also have overload protection and surge protection functions. However, the number of power outlets on a power strip is limited. When multiple devices need power, there may not be enough outlets. Using a large power strip directly can be inconvenient, as it occupies space when the number of devices to be powered decreases, and replacing it with a smaller one is cumbersome. This necessitates an extendable power strip, which allows for the addition of more outlets when multiple devices need power, and reduces the number of outlets when the number of devices to be powered decreases. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model provides a novel expandable power strip to solve the issue that existing power strips cannot expand or change the number of sockets according to the number of devices to be powered.
[0004] This utility model discloses a novel expandable power strip, achieved through the following specific technical means:
[0005] A novel expandable power strip includes: a power cord; the power cord extends into the power strip housing, the power strip housing is circular, a power switch is provided on the rear side of the upper side of the power strip housing, a USB port is provided at the center of the upper side of the power strip housing, two sets of two-hole sockets are provided on both the left and right sides of the USB port, three sets of three-hole sockets are provided on both the front and rear sides of the USB port, a connection socket is provided on the left and right sides and the front of the side of the power strip housing, and five sets of circular anti-slip pads are provided on the bottom of the power strip housing.
[0006] Furthermore, the power strip housing has a set of arc-shaped sliding openings on the left, right, and front sides of its upper surface.
[0007] Furthermore, the power strip housing has an inner shell inside, and the upper side of the inner shell has a USB port, a two-hole port, and a three-hole port corresponding to the upper side of the power strip housing. There are cavities between the inner shell and the power strip housing on the side and top, and a set of isolation blocks are provided on the left, right and front sides of the cavities.
[0008] Furthermore, the isolation block is in the shape of an inverted "L", and a lever is provided at the upper left end of the isolation block. The upper end of the lever extends out of the socket housing through a sliding port, and the lever drives the isolation block to slide in the cavity.
[0009] Furthermore, the connection socket is connected to a connector plug, which is connected to an extension strip. The extension strip is arc-shaped, with three sets of two-hole sockets on the inner ring and five sets of three-hole sockets on the outer ring. The bottom of the extension strip has two sets of circular anti-slip pads.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] 1. This utility model, by setting up an extension strip, allows for flexible switching and convenient use. When it is necessary to increase the number of power outlets on the extension strip, the connector of the extension strip is inserted into the connector. When it is necessary to reduce the number of power outlets on the extension strip, the connector of the extension strip is unplugged.
[0012] 2. This utility model features an insulating plate that rotates into the cavity when the extension strip is inserted and rotates out after the extension strip is removed, blocking the connection port and preventing foreign objects from entering the connection port, as well as preventing children from sticking their fingers in and getting an electric shock.
[0013] 3. This utility model prevents children from directly inserting their fingers into the socket and getting an electric shock by setting a cavity above the outer shell and inner shell of the power strip. Attached Figure Description
