Description

Technical Field

[0001] The utility model belongs to the technical field of power expansion docks, and in particular relates to a novel power expansion dock. Background Art

[0002] A power strip is a multi-socket power socket that can expand one power socket into multiple ones, so that users can power multiple devices at the same time. Usually, the power strip is equipped with a power switch and overload protection function to ensure safety.

[0003] In the prior art, a conventional power docking station is usually used by directly plugging a power cord into a power socket. However, this usage method has some inconveniences. First, since the power cord is directly exposed, it is easy to cause accidental touches, resulting in the power cord being accidentally unplugged from the power socket, thereby causing the device connected to the power docking station to lose power. This situation will cause inconvenience during use and may even cause device damage or data loss. Secondly, frequent accidental touches and unplugging may cause physical damage to the power cord and socket, affecting their service life. Therefore, in order to improve the stability and ease of use of the power docking station, it is necessary to improve and optimize it. Utility Model Content

[0004] The purpose of the utility model is to overcome the problems in the prior art that the power cord is directly exposed to the outside, which may easily cause accidental touches, resulting in the power cord being accidentally unplugged from the power socket, thereby causing the device connected to the power expansion dock to lose power. This situation will cause inconvenience during use and may even cause device damage or data loss. Secondly, frequent accidental touches and plugging and unplugging may cause physical damage to the power cord and the socket, affecting their service life. A new power expansion dock is provided, which has the effect of preventing the DC output interface from being accidentally touched and unplugged.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new power expansion dock, comprising an adapter interface and a power expansion module, the adapter interface and the power expansion module are electrically connected to each other through a power cord, an AC output interface is provided on one side surface of the power expansion module, an interface groove is provided on the other side surface of the power expansion module, a plurality of DC output interfaces are installed on the inner surface of the interface groove, sliding grooves are provided on both sides of the interior of the interface groove, a second protective cover is slidably connected to the interior of the sliding groove, the second protective cover penetrates and slides and is connected to the inner upper end of the interface groove, a spring structure is provided between the lower end of the second protective cover and the inner bottom end of the sliding groove, and a plurality of wire holes are penetrated on the surface of the second protective cover.

[0006] Preferably, a handle is fixedly connected to the upper surface of the second protective cover.

[0007] Preferably, a wire groove is provided on the upper surface of the power extension module.

[0008] Preferably, a first protective cover is hingedly connected to the inner upper end of the wire trough.

[0009] Preferably, the first protective cover and the wire trough are hinged to each other via a hinge.

[0010] Preferably, the adapter interface and the AC output interface are of the same shape and size.

[0011] Preferably, the second protective cover and the first protective cover are both made of transparent plastic material.

[0012] Compared with the prior art, the new power expansion dock provided by the utility model has the following beneficial effects:

[0013] 1. The utility model provides a second protective cover. Before the DC output interface is connected, the second protective cover is pulled upward by the handle. After the DC output interface is connected, the handle is released, and the spring structure covers the second protective cover inside the interface slot. The DC output interface is locked and protected through the wire hole, thereby preventing the DC output interface from being accidentally touched and unplugged. This effectively avoids the problem that the power cord is directly exposed to the outside and is easily accidentally touched, resulting in the power cord being accidentally unplugged from the power socket, thereby causing the device connected to the power expansion dock to be powered off. This situation will cause inconvenience during use and may even cause device damage or data loss. Secondly, frequent accidental touches and plugging and unplugging may cause physical damage to the power cord and socket, affecting their service life.

[0014] 2. The utility model provides a wire trough and a first protective cover. When the power cord is too long, the excess power cord is wound inside the wire trough, and the second protective cover is covered on top of the wire trough to protect and store the excess power cord, making the power docking station more portable when used.

[0015] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. BRIEF DESCRIPTION OF THE DRAWINGS
