The present invention relates to a cable-winding device, and more particularly to a planar cable-winding device.
Cable-winding devices are often used in household power supply, electricity and maintenance testing projects and other occasions. In general, a cable-winding device includes a power module. There are two types of cable-winding devices on the market. One is a three-dimensional cable-winding device, and the other is a planar cable-winding device.
A three-dimensional cable-winding device includes a bracket, a cable-winding reel, and a lever. The rear of the cable-winding reel is provided with a pivot. The cable-winding reel is movably mounted on the bracket through the pivot. The lever is disposed on the pivot. When in use, the bracket is supported on the ground, and the user operates the lever to drive the cable-winding reel to rotate for winding and unwinding a power cable. However, this three-dimensional cable-winding device is big in size, and it is more suitable for large power cable reels. As to a small power cable reel, its height is small. It is troublesome for the user to place the three-dimensional cable-winding device on the ground and bend down to operate the three-dimensional cable-winding device. Besides, it is not convenient to carry the three-dimensional cable-winding device. For a small power cable reel, the three-dimensional cable-winding device occupies much space.
A planar cable-winding device usually includes an H-shaped cable-winding frame. A power cable is wound on the H-shaped cable-winding frame. It is small in size and easy to carry. However, when the power cable is to be wound up, the user holds the frame with one hand and wind the power cable around the frame with the other hand. When the cable is to be unwound, the user unwinds the cable in an opposite direction manually. This operation is more troublesome, time-consuming and labor-intensive.
In view of the deficiencies of the prior art, the primary object of the present invention is to provide a planar cable-winding device. On the premise of taking up less space, a power cable can be wound up and unwound quickly. It is easy to operate the planar cable-winding device, having a good experience of use.
In order to achieve the above object, the present invention adopts the following technical solutions:
A planar cable-winding device comprises a cable-winding frame. The cable-winding frame includes a left cable-winding segment, a right cable-winding segment spaced apart and facing away from the left cable-winding segment, and a connecting arm connected between the left cable-winding segment and the right cable-winding segment. The left cable-winding segment has a left cable-winding groove that has a left opening and passes through front and rear sides of the cable-winding frame. The right cable-winding segment has a right cable-winding groove that has a right opening and passes through the front and rear sides of the cable-winding frame. The left cable-winding groove and the right cable-winding groove are arranged symmetrically.
The connecting arm has a first rotating shaft hole. A handle is disposed above the connecting arm. The handle has a second rotating shaft hole. A rotating shaft is disposed in the second rotating shaft hole. The rotating shaft extends downward into the first rotating shaft hole and is rotatable relative to the cable-winding frame about its own axis. The handle further has a retaining pin and a first retaining hole. The connecting arm further has a second retaining hole. The second retaining hole is located beside the first rotating shaft hole. The first retaining hole is located beside the second rotating shaft hole. The retaining pin is pluggable and inserted into the first retaining hole and the second retaining hole in sequence. A lever is disposed on a bottom of the left cable-winding segment or a bottom of the right cable-winding segment.
A power socket is disposed on the cable-winding frame between the left cable-winding segment and the right cable-winding segment. The power socket is located below the connecting arm. The power socket has a power input interface and at least one power output interface that are electrically connected.
Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions, the present invention includes the handle, the connecting arm, the rotating shaft, the first rotating shaft hole, the second rotating shaft hole, the retaining pin, the first retaining hole, the second retaining hole and the lever. When the power cable is to be wound up, the retaining pin is unplugged, and the user holds the handle with one hand and operates the lever to wind up the power cable with the other hand. After the power cable is wound up, the retaining pin is plugged. The handle is independent from the top of the cable-winding frame, and will not interfere with the left cable-winding groove and the right cable-winding groove. The shape and size of the handle can be designed freely and flexibly, and will not be subject to the design and production of the cable-winding frame. The arrangement of the handle meets the hand-held operation. If the user wants to wind up the power cable manually, the retaining pin is plugged so that the handle and the cable-winding frame cannot rotate relative to each other. When the power cable is to be unwound, the retaining pin is unplugged and one end of the power cable is pulled to be unwound quickly. On the premise of taking up less space, the power cable can be wound up and unwound quickly. It is easy to operate the planar cable-winding device, having a good experience of use.
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.
