Problems solved by technology

In certain occasions, it is necessary to use cables through the wall, such as charging electric vehicles in the stairwell of a residential building. If the power cord winder is also installed in the stairwell, if there are too many installations, the site will be crowded and easy to be stolen. , also prone to safety accidents
In this case, it is necessary to make a hole in the wall, then pass the cable through the hole, and then use it. However, in the process of retracting the cable, friction between the cable and the hole wall is inevitable, and the cable is easy to wear , and even unsafe situations such as electric leakage and liquid leakage

Embodiment Construction

[0019] The method is: 1. Punch a hole on the wall (or door and window frame), install the wire winder on one side of the hole, and keep the protruding cable concentric with the hole. A guide wheel is installed under the other side of the hole, and the cable passes through the guide wheel after passing through the hole. 2. Make a hole on the wall (or door and window frame), install the wire winder on one side of the hole, the protruding cable and the hole are not in a straight line, guide wheels are installed on both sides of the hole, and the cable passes through a The side guide wheel passes through the hole, and finally passes through the guide wheel on the other side.

[0020] The axle of guide wheel is installed on the support, and support is fixed on the wall (or door, window), and guide wheel adopts concave groove tangentially, and its radial projection is bone shape. The contact area with the cable can be increased to facilitate cable positioning.

Abstract

The invention discloses an improved winder, which mainly comprises a winding roller, a cable, a bracket and a guide wheel. By the guide wheel, the winding roller is arranged on one side of a wall, and the cable is arranged on the other side of the wall, so that the wall surface is attractive in appearance and is kept neat, and the safety is improved.

Description

technical field [0001] The invention relates to a wire winder, in particular to an improved wire winder, which is more convenient and easy to use when the cable passes through the wall (or door, window). Background technique [0002] The winder is also called a hose reel, a wire reel, a reel, and a drum. It is mainly composed of a bracket, a rotating shaft, and a winding drum. Usually a return spring or an electric motor is used to provide the power for cable retrieval. It often has a self-locking device, that is, the extension length of the cable of the winder can be adjusted through the three actions of releasing, retracting and resting the cable. Realize instant pull and stop, automatic recycling. [0003] In practical applications, the cable winder is generally located at the same location as the cable. In certain occasions, it is necessary to use cables through the wall, such as charging electric vehicles in the stairwell of a residential building. If the power cord...
