[0002] LED driver power supply is a power converter that converts power supply into a specific voltage and current to drive LED to emit light. Usually, the input of LED driver power supply includes high-voltage industrial frequency AC (i.e. mains), low-voltage DC, high-voltage DC, low-voltage high-frequency AC (such as the output of electronic transformer), etc., while the output of LED driver power supply is mostly a constant current source that can change voltage as the forward voltage drop value of the LED changes.

[0033] The utility model sets a fixing assembly 3. When the protective shell A201 and the protective shell B202 are in contact with each other, the L-shaped member 312 passes through the groove 304 and moves into the empty groove 303. In addition, the fixed block 301 and the fixed plate 302 are in contact with each other. Then, the reset rod 316 is pressed to move the reset rod 316, so that the spring C317 is stretched under force, so that the movable block 305 slides in the empty groove 303, and the limit block 314 squeezes the fixed wedge block 308, so that the limit block 314 slides in the sliding groove 313 ... spring C317 is stretched under force, so that the movable block 305 slides in the empty groove 303, so that the spring C317 is stretched under force, so that the movable block 305 slides in the empty groove 303, and the limit block 314 squeezes the fixed wedge block 308, so that the limit block 314 slides in the sliding groove 313, so that the spring C317 is stretched under force, so that the spring C317 is stretched under force, so that the spring C317 is stretched under force, so that the movable block 305 slides in the empty groove 303, and the spring C317 is stretched under force, so that the spring C317 is stretched under force, so that the spring C317 is stretched under force, so that the spring C317 is stretched under force, so that the spring C317 is stretched The spring B315 contracts under force until the limit block 314 moves to between the fixed wedge block 308 and the movable wedge block 309. At this time, the spring B315 is no longer under force and begins to stretch, causing the limit block 314 to slide in the opposite direction in the sliding groove 313 until the spring B315 returns to its original shape. At this time, the vertical plate of the L-shaped part 312 contacts the connecting groove 311, and the horizontal plate of the L-shaped part 312 contacts the side of the movable block 305, so that the protective shell A201 and the protective shell B202 are fixed on the LED driver power supply body 1.

This facilitates the separation of the protective shell A201 and the protective shell B202 by squeezing the inclined surface of the fixed wedge block 308 and the inclined surface of the movable wedge block 309 through the limit block 314.

[0035] As a preferred embodiment, the limit block 314 is in a right-angle trapezoidal structure, and the inclined surface of the limit block 314 is arranged close to the movable wedge block 309, and the inclined surface of the limit block 314 contacts the inner wall of the sliding groove 313.

[0038] The LED driving power supply body 1 is a conventional instrument, and its working principle, size and model are irrelevant to the problem solved by the present application, so no further description will be given. The control method of the present invention is controlled by a controller, and the control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0039] How it works

[0040] When the outdoor LED driving power supply is in use, the protective shell A201 and the protective shell B202 are both put on the LED driving power supply body 1, and the sealing block 203 is inserted into the sealing groove 204 until the end face of the sealing block 203 contacts the inner wall of the sealing groove 204. At this time, the protective shell A201 and the protective shell B202 are in contact with each other, and the L-shaped member 312 passes through the groove 304 and moves into the empty groove 303, and the fixed block 301 and the fixed plate 302 are in contact with each other. Then, the reset rod 316 is pressed to move the reset rod 316, so that the spring C317 is stretched under force, and the movable block 305 slides in the empty groove 303, so that the limit The inclined surface of block 314 squeezes the inclined surface of fixed wedge block 308, so that the limit block 314 slides in the sliding groove 313, and the spring B315 is forced to shrink until the limit block 314 moves between the fixed wedge block 308 and the movable wedge block 309. At this time, the spring B315 is no longer stressed and begins to stretch, so that the limit block 314 slides in the opposite direction in the sliding groove 313 until the spring B315 returns to its original shape. At this time, the vertical plate of the L-shaped member 312 contacts the connecting groove 311, and the horizontal plate of the L-shaped member 312 contacts the side of the movable block 305, so that the protective shell A201 and the protective shell B202 are fixed on the LED driver power supply body 1;When it is necessary to disassemble the protective shell A201 and the protective shell B202, the reset rod 316 is pressed to move the reset rod 316, so that the spring C317 is stretched under force, the movable block 305 slides in the empty slot 303, and the inclined surface of the limit block 314 squeezes the movable wedge block 309, so that the movable wedge block 309 slides on the fixed rod 307, and the spring A310 is forced to shrink until the spring A310 shrinks to the maximum limit. At this time, the inclined surface of the limit block 314 will squeeze the movable wedge block 309, so that the limit block 314 slides in the sliding groove 313, and the spring B315 is forced to shrink until the end of the limit block 314 contacts the inclined surface of the movable wedge block 309. At this time, the spring B315 returns to its original shape. Then, the reset rod 316 is released, the spring A310 is no longer stressed and begins to stretch, and the spring C317 is no longer stressed and begins to shrink, so that the reset rod 316 moves in the opposite direction. The movable block 305 slides in the opposite direction in the empty slot 303, so that the limit block 314 drives the movable wedge block 309 to slide in the opposite direction on the fixed rod 307 until the fixed wedge block 308 and the movable wedge block 309 contact each other. At this time, the spring A310 is in a stretched state, and due to the contraction of the spring C317, the end of the limit block 314 squeezes the inclined surface of the movable wedge block 309, so that the limit block 314 slides in the sliding slot 313, and the spring B315 is forced to contract until the end of the limit block 314 contacts the inclined surface of the fixed wedge block 308. At this time, the spring B315 is no longer stressed and begins to stretch, so that the limit block 314 slides in the opposite direction in the sliding slot 313 until the spring C317 returns to its original shape. At this time, the L-shaped piece 312 is no longer in contact with the connecting slot 311, and the protective shell A201 and the protective shell B202 can be removed from the LED driver power supply body 1. ;
