Adjustable steering electrical appliance and adjusting mechanism thereof

Technical Field

The utility model belongs to the technical field of electrical apparatus and structure and specifically relates to an adjustable electrical apparatus that turns to and adjustment mechanism thereof.

Background

When using an electrical appliance, such as a lamp, a user may adjust the posture of the desk lamp to provide different lighting angles according to different requirements. This involves the wires being pulled around, and most common designs have a movable structure at the base to allow the base to be selectively adjusted according to the user's preference. As shown in fig. 1 and 2, one of the prior art lamp designs is to connect the lamp head 101P to the lamp body 100P in a structure that can be selectively installed at 360 °, so that the lamp head 101P can be adjusted to various angles to provide illumination. For other electric appliances, such as a charging device, similarly, the orientation is adjusted by the direct-connection rotating shaft 103P or the external-connection rotating shaft 104P. However, one of the disadvantages of this design is that the rotating shaft capable of rotating 360 ° can rotate 180 ° up and down horizontally, which causes the wires 102P connected between the fixed top end of the rotating shaft and the rotating end of the rotating shaft to be spirally mixed together, as shown in the enlarged view angle a in fig. 1, when the user adjusts for many times, the user often cannot know the current optional situation, which may result in gradually increasing the number of rotating turns, the stress of the mixing between the wires will also increase synchronously, and finally the wires 102P should be broken by too much stress, which results in product damage and failure to work. Even for some wires 102P made of special materials, the metal inside the wires may be broken due to the large angle of the wire, which may cause a circuit safety hazard. The other disadvantage is that the lead 102P externally connected to the rotating shaft 104P is often exposed outside the lamp housing, which not only affects the appearance, but also may be touched by human body, and has a certain potential safety hazard.
