Description

Technical Field

[0001] This utility model relates to the field of power equipment protection technology, specifically an extension cord protection device. Background Technology

[0002] Extension cords, also known as power strips, are commonly plug-in type. This means that the ordinary plug of an appliance is directly inserted into the socket of the power strip to achieve the purpose of power supply. They are simple in structure and easy to use. Therefore, with the widespread use of various electrical devices, power strips have become a common power extension device in daily life.

[0003] The exposed sockets of commonly used household power strips pose a safety hazard, especially when used outdoors where extension cords are needed. These power strips are easily affected by the external environment, such as dust accumulation or rain damage. Existing technology includes protective boxes for extension cords, where the power strip is placed inside the box and closed to form a sealed enclosure. The power cord and connecting wires to the power strip exit through openings in the side wall of the box, with a sealing component at the opening to protect the power strip. However, even with the cord extended, rainwater can still seep into the enclosure during heavy rain, posing a risk to the electrical conductivity of the power strip. Furthermore, existing power strip protective boxes are bulky when the box and cover are closed together, making storage and transportation inconvenient. Therefore, this paper proposes an extension cord protection device to improve the waterproof performance at the cord opening, reducing the risk of rainwater intrusion, and to reduce the required volume during transportation and storage, saving storage space.

[0007] Preferably, a lower boss is provided at the wire hole on both sides of the box body, and a limiting protrusion is provided on the outer wall of the lower boss. The limiting protrusion is provided in correspondence with the rotating shaft hole. A snap hook is provided below the water-blocking component, and the water-blocking component is fastened to the limiting protrusion.

[0008] Preferably, the limiting protrusion includes a lower limiting protrusion, which is disposed at the bottom of the lower boss and corresponds to the upper rotating shaft hole.

[0009] Preferably, the limiting protrusion includes a side limiting protrusion, which is disposed on the side wall of the lower boss, and the side limiting protrusion is correspondingly disposed with the side rotating shaft hole.

[0010] Preferably, it also includes a fastening assembly, which includes a fastening seat, a fastening ring, and a fastening protrusion. The fastening seat is disposed on the outer wall of the box, the fastening ring is hinged to the fastening seat, and the fastening protrusion is fixed on the outer wall of the cover and is disposed corresponding to the fastening ring. The fastening ring rotates to engage the fastening protrusion.

[0011] Preferably, the cover further includes a sealing groove disposed on the top of the inner wall of the cover, and a sealing assembly comprising a sealing ring and a sealing plug, wherein the top of the sealing ring is snapped into the sealing groove, and the bottom of the sealing ring abuts against the upper edge of the cover.

[0012] Preferably, the water-blocking assembly further includes a water-blocking curtain, the water-blocking curtain being arc-shaped, a snap-fit ​​protrusion being provided on one side of the water-blocking cover, a snap-fit ​​hole being provided on the mounting base, and one end of the water-blocking curtain being snapped onto the mounting base.

[0013] Preferably, the outer periphery of the box body corresponds to the inner cavity of the lid body. In the stored state, the outer wall of the box body abuts against and fits into the inner cavity of the lid body to form a storage arrangement.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] By setting an external water-blocking component that can adjust the installation direction according to whether the protective box is placed flat or vertically during use, the waterproof performance is improved, the installation is convenient, and rainwater is prevented from falling into the cavity through the lead hole during rainfall, thus ensuring the safety of the extension wire wiring device inside the box.

[0016] By setting the inner wall size of the lid to form an internal cavity that matches the outer wall size of the box, after the box and lid are opened and separated, the lower part of the box is placed into the inner cavity of the lid. This achieves the effect of reducing the space required for storage and transportation compared to directly fastening the two together or simply stacking them, making storage and transportation easier.

[0017] By using multiple layers of semi-circular sealing plugs and sealing components to fix the exposed wires, dust and rainwater can be prevented from entering the internal cavity of the external protection device, reducing the risk of electrical hazards. Attached Figure Description
