Speed-adjustable power supply device with funnel-shaped guide hole

Abstract

A speed-adjustable power supply device with a funnel-shaped guide hole comprises a main body (9) and a plug (6) plugged into a jack of the main body (9), a locking and unlocking motor (91) is arranged in the main body (9), an electronic control device (97) is arranged on a casing of the locking and unlocking motor (91), is in signal connection with the locking and unlocking motor (91) and used for controlling the rotating speed of the locking and unlocking motor (91), a rotor of the locking and unlocking motor (91) is in power connection with a screw rod (95), the screw rod (95) is in thread fit with a screw hole in a movable component (8) in the main body (9), and a stator of the locking and unlocking motor (91) is fixedly connected with a power supply guide rod (74) which glidingly penetrates through a sliding hole formed in the movable component (8) and is in sliding fit with the sliding hole.

Description

technical field [0001] The present application relates to the field of power supply devices, in particular to a speed-adjustable power supply device with a funnel-shaped guide hole. Background technique [0002] When the power supply equipment is plugged into the power supply, a relatively stable mechanical connection is required. [0003] In the prior art, the friction between the socket and the pin is used to realize the locking of the inserted state. [0004] This kind of socket is prone to sparking during use. However, in some prior art, the plug is mechanically locked by using a bevel-shaped locking pin. But this kind of locking pin also needs to frictionally fit and slide when it works, so it also causes hidden dangers to the use safety. Moreover, when the power needs to be cut off, this interface requires the plug to be disconnected from the socket to realize electrical disconnection, which requires frequent plugging and unplugging of the plug in the case of freque...

Problems solved by technology

But this kind of locking pin also needs to frictionally fit and slide when working, so it also causes hidden dangers to the use safety.

Moreover, when the power needs to be cut off, this interface requires the plug to be disconnected from the socket to realize electrical disconnection, which requires frequent plugging and unplugging of the plug in the case of frequent power-off and power-on, which causes trouble to the operation.
