Description

Technical Field

[0001] The utility model relates to the field of switching power supply related products, in particular to an anti-mistouch switching power supply. Background Art

[0002] A switching power supply is a power supply that uses modern power electronics technology to control the ratio of the time when the switch is turned on and off to maintain a stable output voltage. A switching power supply is generally composed of a pulse width modulation (PWM) control IC and a MOSFET. With the development and innovation of power electronics technology, switching power supply technology is also constantly innovating. At present, switching power supplies are widely used in almost all electronic devices due to their small size, light weight and high efficiency. They are an indispensable power supply method for the rapid development of today's electronic information industry.

[0003] However, most of the existing switch power control panels are exposed to the outside, which is easy to cause accidental touches, resulting in accidental touches when power is needed to be turned on or off, causing the power to be disconnected or turned on, thereby affecting the required working state. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-mistouch switching power supply to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a switching power supply with an anti-false touch function, comprising a switching power supply body and a protective cover, a supporting block is fixedly connected to an outer wall of one side of the switching power supply body, a groove is provided on one side of the supporting block, a rotating rod is rotatably connected in the groove, a traction plate is fixedly sleeved on the rotating rod, one end of the traction plate is fixedly connected to the protective cover, a positioning frame is fixedly connected to the other side of the switching power supply body, a pressure plate is provided in the positioning frame, two symmetrically arranged slides are fixedly connected to one side of the pressure plate, the slide is slidably inserted in the positioning frame, a return plate is fixedly connected to one end of the slide, a plurality of elastic mechanisms are fixedly connected between one side of the return plate and the positioning frame, an insert plate is fixedly connected to an outer wall of one side of the protective cover, and a wedge plate is fixedly connected to the outer side wall of the insert plate.

[0006] Preferably, the plurality of elastic mechanisms are all springs.

[0007] Preferably, torsion springs are provided on both sides of the rotating rod, and two ends of the torsion springs are respectively fixed to the traction plate and the inner wall of the groove.

[0008] Preferably, a pull ring is fixedly connected to an outer wall of one side of the response plate.

[0009] Preferably, the outer surface of the wedge-shaped plate is provided with a polished structure.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The anti-mis-touch switching power supply drives the rotating rod to rotate in the groove on the supporting block by flipping the traction plate, so that the protective cover is clamped on the surface of the switching power supply body. At this time, the plug plate on the other side of the protective cover will be inserted into the positioning frame, and the wedge plate will squeeze the pressing plate, and the pressing plate will drive the sliding plate to push the return plate to move. At this time, the return plate will stretch the elastic mechanism. After the plug plate is fully inserted, the elastic mechanism in the stretched state will rebound, so that the pressing plate will be pressed against the top of the wedge plate to fix the protective cover. The utility model can effectively prevent the switching power supply from being accidentally touched by the provision of the protection component. BRIEF DESCRIPTION OF THE DRAWINGS
