DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 The utility model provides an embodiment: an anti-mistouch housing for a switching power supply, comprising a power box 1 and a power protection housing 2, the power protection housing 2 is made of hard plastic, the power protection housing 2 is movably plugged into the outside of the power box 1, a switch protection cover 7 is clamped on the front end of the power protection housing 2, two extended protection covers 8 are symmetrically fixedly connected to the rear end of the power protection housing 2, and two fixing plates 9 are symmetrically fixedly connected to the side of the extended protection cover 8 away from the power protection housing 2.

[0022] The inner side of the power supply protection shell 2 is evenly fixedly connected with a heat dissipation support rod 10, and the heat dissipation of the power supply box 1 is facilitated by the gap between the heat dissipation support rods 10. A plug-in slot 11 is provided at the rear end of the extended protective cover 8. A movable telescopic baffle 12 is movably plugged into the side of the extended protective cover 8 away from the power supply protection shell 2. The end of the movable telescopic baffle 12 away from the extended protective cover 8 is fixedly connected with a pull rod 14. The top and bottom ends of the movable telescopic baffle 12 are symmetrically fixedly connected with a sliding connection plate 13 near the pull rod 14. A limit card frame 15 is fixedly installed on the fixed plate 9. The limit card Two limit guide slide bars 17 are symmetrically threadedly connected on the frame 15, and a return spring 16 is embedded on the outer side of the limit guide slide bar 17. A power switch 3 is provided at the front end of the power box 1, and the power switch 3 is located inside the switch protective cover 7. A heat dissipation top cover 4 is fixedly installed on the top of the power box 1, and the power box 1 can be effectively cooled by the heat dissipation top cover 4 on the top. Four fixed feet 5 are symmetrically fixedly connected on both sides of the rear end of the power box 1, and a fixing round rod 6 is fixedly connected between the two fixing feet 5 on the same side of the power box 1, and the fixing round rod 6 is movably plugged into the inner side of the plug-in slot 11.

[0023] The movable telescopic baffle 12 is beveled at one end away from the pull rod 14 and at one side away from the power supply protective casing 2. The beveled design facilitates the fixing round rod 6 to squeeze the movable telescopic baffle 12 to contract, and facilitates the installation of the power supply protective casing 2 on the outside of the power supply box 1. The fixing round rod 6 pushes the movable telescopic baffle 12 away from the extended protective cover 8. The movement of the movable telescopic baffle 12 drives the sliding connecting plate 13 to slide on the outside of the limiting guide slide rod 17 while squeezing the reset spring 16 to contract.

[0024] The limiting guide slide bar 17 is movably inserted on the sliding connecting plate 13, and the reset spring 16 is limited by the limiting guide slide bar 17. When the sliding connecting plate 13 slides on the outside of the limiting guide slide bar 17 close to the limiting card frame 15, the sliding connecting plate 13 squeezes the reset spring 16 to contract, and the pull rod 14 is movably inserted on the limiting card frame 15.

[0025] Working principle: During use, first install and fix the power box 1 through the fixed feet 5 and turn on the power through the power switch 3, then use external force to plug the power protection shell 2 into the front end of the power box 1, and push the power protection shell 2 to be inserted into the outside of the power box 1 through external force. When the fixed round rod 6 contacts the beveled edge of the movable telescopic baffle 12, the fixed round rod 6 pushes the movable telescopic baffle 12 away from the extended protective cover 8, and the movement of the movable telescopic baffle 12 drives the sliding connecting plate 13 to slide on the outside of the limiting guide slide rod 17 while squeezing the reset spring 16 to contract. When the movable telescopic baffle 12 moves to completely disengage from the inner side of the plug-in slot 11, the extended protective cover 8 moves to the outside of the fixed feet 5 under the push of external force. At this time, the reset spring 16 loses pressure and rebounds to push the sliding connecting plate 13 to move away from the limiting card frame 15. The movement of the sliding connecting plate 13 drives the movable telescopic baffle 12 to move to the inner side of the plug-in slot 11 to restore the initial position. The movable telescopic baffle 12 is in the position, and the movable telescopic baffle 12 is close to the outer side of the fixed round rod 6 away from the beveled side to fix the power supply protective shell 2. At this time, the power switch 3 is located on the inner side of the switch protective cover 7. The switch protective cover 7 protects the power switch 3 to avoid accidental touch. At the same time, the power supply box 1 is protected by the power supply protective shell 2 to avoid electric shock. When it is necessary to turn off the power, the two pull rods 14 are pulled outward at the same time by external force. The movement of the pull rods 14 drives the movable telescopic baffle 12 to move away from the power supply protective shell 2 until the movable telescopic baffle 12 is completely separated from the inner side of the plug-in slot 11. At this time, the two pull rods 14 are pulled toward the front end by external force. The movement of the pull rods 14 drives the power supply protective shell 2 away from the power supply box 1 until the power supply protective shell 2 is completely separated from the outside of the power supply box 1. At this time, the power can be turned off by the power switch 3. After turning off the power, the power supply protective shell 2 can be plugged into the outside of the power box 1 by external force. The operation is convenient.
