[0002] A switching power supply is a power supply device that uses high-frequency switching technology to convert input AC or DC power into a stable DC output. Its main functions include voltage and current conversion, voltage regulation, and improving energy efficiency. The switching power supply first converts the input AC power into DC power through a rectifier bridge and filter to provide basic power for subsequent circuits.

[0003] When using existing switching power supplies, their function is to convert AC or DC power into the required stable DC output. Existing switching power supplies do not have a mechanism to prevent accidental contact. After connecting the wiring harness, it is easy to cause electric shock due to accidental contact with the wiring harness interface. Utility Model Content

[0004] The purpose of this utility model is to provide a switching power supply that prevents accidental contact, so as to solve the problem mentioned in the background art that the existing switching power supply does not have an anti-accidental contact mechanism, and after connecting the wiring harness, it is easy to cause electric shock due to accidental contact with the wiring harness interface.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a switching power supply to prevent accidental touch, comprising:

[0006] The device body includes a device body, and a wire harness interface is provided on the surface of the device body.

[0007] The top of the device body is provided with a protective mechanism, which includes a fixed frame. A support frame is connected to the top of the fixed frame. An adjusting screw is inserted inside the support frame. A bearing is provided on the outer surface of the bottom end of the adjusting screw. A hinge rod is hinged to both sides of the bearing. A limit rod is hinged to the bottom end of the hinge rod. A protective cover is sleeved on the outer wall of one end of the limit rod.

[0008] Preferably, the top surface of the support frame has a threaded hole, the adjusting screw is rotatably connected to the threaded hole of the support frame, the top surface of the fixing frame has a through groove, and the hinge rod is inserted into the through groove of the fixing frame.

[0009] Preferably, the adjusting screw and the hinge rod are movably connected by bearings, and the hinge rod has movable grooves on both sides of the inner wall of the through groove, and the limiting rod is inserted into the movable groove of the hinge rod.

[0010] Preferably, the top surface of the protective cover has a groove, and the inner walls of the groove of the protective cover have limit grooves on both sides, and one end of the limit rod is inserted into the limit groove of the protective cover.

[0011] Preferably, an assembly structure is connected to one side of the top surface of the device body. The assembly structure includes a fixing screw, a positioning frame sleeved on the outer wall of the fixing screw, a nut rotatably connected to the outer surface of the top of the fixing screw, torsion springs connected to both sides of the positioning frame, a fixing sleeve connected to one end of the torsion spring, and a protective shell connected to one end of the fixing sleeve.

[0012] Preferably, the top surface of the positioning frame has a slot, and the fixing screw is inserted into the slot of the positioning frame.

[0013] Preferably, the fixing screw and the nut are rotatably connected by a thread, and one end of the torsion spring is connected to one side of the inner surface of the fixing sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By rotating the adjusting screw, it moves within the threaded hole of the support frame. The bearing ensures that the rotation of the adjusting screw does not affect the angle of the hinge rod. The adjusting screw and bearing drive the limiting rod connected to the bottom of the hinge rod to slide within the movable groove of the fixed frame. One end of the limiting rod is inserted into the limiting groove of the protective cover. The limiting rod restricts the angle of the protective cover, allowing the protective cover to fit over the outer surface of the wire harness interface, isolating the wire harness interface without affecting the wire harness connection. This prevents accidental contact with the wire harness interface and avoids the problem of electric shock caused by accidental contact.

[0016] 2. By fitting the positioning bracket onto the outer surface of the fixing screw, the fixing screw positions the positioning bracket. Then, the nut is rotated and connected to the outer surface of the top of the fixing screw to limit the positioning bracket. This allows the protective shell to fit onto the outer wall of the adjusting screw for protection. The torque of the torsion spring ensures that the angle between the fixing sleeve and the protective shell does not change. When it is necessary to adjust the angle of the adjusting screw, the torsion spring can be twisted by moving the protective shell, so as not to affect the adjustment of the adjusting screw.

The surface material of the device body 11 is existing technology and can be purchased on the market. It is not considered as a technical protection point of this application, so no further details are made.

[0027] The top of the equipment body 11 is provided with a protective mechanism 2. The protective mechanism 2 includes a fixed frame 21. The top of the fixed frame 21 is connected to a support frame 22. An adjusting screw 23 is inserted inside the support frame 22. A bearing 24 is provided on the outer surface of the bottom end of the adjusting screw 23. A hinge rod 25 is hinged to both sides of the bearing 24. A limit rod 26 is hinged to the bottom end of the hinge rod 25. A protective cover 27 is sleeved on the outer wall of one end of the limit rod 26.

[0028] Furthermore, the top surface of the support frame 22 is provided with a threaded hole, and the adjusting screw 23 is rotatably connected to the threaded hole of the support frame 22. The top surface of the fixed frame 21 is provided with a through groove, and the hinge rod 25 is inserted into the through groove of the fixed frame 21, so that the hinge rod 25 can be moved and limited through the through groove of the fixed frame 21.

[0029] Furthermore, the adjusting screw 23 and the hinge rod 25 are movably connected by the bearing 24. The inner wall of the through groove of the hinge rod 25 is provided with movable grooves on both sides. The limiting rod 26 is inserted into the movable groove of the hinge rod 25, so that the limiting rod 26 can be moved and limited by the movable groove of the hinge rod 25.

[0030] Furthermore, a groove is provided on the top surface of the protective cover 27, and a limiting groove is provided on both sides of the inner wall of the groove of the protective cover 27. One end of the limiting rod 26 is inserted into the limiting groove of the protective cover 27, so that the limiting groove of the protective cover 27 can limit one end of the limiting rod 26.

[0031] Furthermore, an assembly structure 3 is connected to one side of the top surface of the equipment body 11. The assembly structure 3 includes a fixing screw 31, a positioning frame 32 is sleeved on the outer wall of the fixing screw 31, a nut 33 is rotatably connected to the outer surface of the top of the fixing screw 31, and torsion springs 34 are connected to both sides of the positioning frame 32. A fixing sleeve 35 is connected to one end of the torsion spring 34, and a protective shell 36 is connected to one end of the fixing sleeve 35, so as to protect the adjusting screw 23 without affecting the adjustment of the adjusting screw 23.

[0032] Furthermore, a slot is provided on the top surface of the positioning frame 32, and the fixing screw 31 is inserted into the slot of the positioning frame 32 to achieve positioning of the fixing screw 31 through the slot of the positioning frame 32.

[0033] Furthermore, the fixing screw 31 and the nut 33 are rotatably connected by threads, and one end of the torsion spring 34 is connected to one side of the inner surface of the fixing sleeve 35, so that the fixing sleeve 35 limits one end of the torsion spring 34.

[0034] Working principle: When preventing accidental contact of the switching power supply, the adjusting screw 23 is rotated to move inside the threaded hole of the support frame 22. The bearing 24 ensures that the rotation of the adjusting screw 23 does not affect the angle of the hinge rod 25. The adjusting screw 23 and the bearing 24 drive the limiting rod 26 connected to the bottom of the hinge rod 25 to slide inside the movable groove of the fixed frame 21. One end of the limiting rod 26 is inserted into the limiting groove of the protective cover 27. The limiting rod 26 restricts the angle of the protective cover 27, so that the protective cover 27 fits onto the outer surface of the wire harness interface 12, isolating the wire harness interface 12 without affecting the wire harness connection, thereby achieving the effect of preventing accidental contact with the wire harness interface 12.

[0035] When protecting the switching power supply from accidental contact, the positioning bracket 32 ​​is sleeved on the outer surface of the fixing screw 31, and the fixing screw 31 is used to position the positioning bracket 32. Then, the nut 33 is rotated and connected to the outer surface of the top of the fixing screw 31 to limit the positioning bracket 32, so that the protective shell 36 is sleeved on the outer wall of the adjusting screw 23 for protection. The torque of the torsion spring 34 ensures that the angle between the fixing sleeve 35 and the protective shell 36 does not change. When it is necessary to adjust the angle of the adjusting screw 23, the torsion spring 34 can be twisted by turning the protective shell 36, so as not to affect the adjustment of the adjusting screw 23.
