[0029] 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.

[0030] See also Figure 1-6 The utility model provides a technical solution: an LED driving power supply for preventing electric wires from falling off, comprising a shell 1, a box cover 2, a circuit board 3, a cylinder 4, a groove 5, a baffle 6, a spring 7, a slot 8, a card block 1 9, a knob 10, a card block 2 11, a slider 12, a heat dissipation hole 13, and a heat dissipation fan 14.

[0031] This device has the effect of preventing the wire from falling off, specifically:

[0032] The shell 1 is an open box structure, the upper surface of the shell 1 is rotatably connected with a box cover 2, the bottom surface of the shell 1 is provided with a circuit board 3, the side surface of the shell 1 is provided with an anti-slip structure, the anti-slip structure uses a cylinder 4 to limit the position of the wire, and the anti-slip structure includes a cylinder 4, the cylinder 4 is a through structure, the inner wall of the cylinder 4 is provided with a groove 5, the inner wall of the groove 5 is rotatably connected with a baffle 6, the lower surface of the baffle 6 is provided with a spring 7, and the other end of the spring 7 is fixed to the bottom surface of the groove 5, the inner wall of the cylinder 4 is annularly provided with a plurality of grooves 5 and baffles 6, the baffle 6 forms a barb-shaped structure on the inner wall of the cylinder 4, and the rotating shaft of the baffle 6 is located on the side of the cylinder 4 close to the outside world, the two side surfaces of the shell 1 are respectively provided with cylinders 4, and the cylinder 4 is aligned with the upper surface of the circuit board 3;

[0033] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, when the wire is connected to the device, the wire is inserted into the cylinder 4 on the side surface of the housing 1 and connected to the circuit board 3 by welding. The cylinders 4 on both sides have the same structure. Figure 6 For example, the wire enters the device from the left side of the cylinder 4. When the wire moves from the left side to the right side of the cylinder 4, the wire exerts a force on the surface of the baffle 6, pushing the baffle 6 in the direction of the groove 5, causing the baffle 6 to rotate on the inner wall of the groove 5 and compressing the spring 7. When the wire is connected to the circuit board 3, the baffle 6 rebounds under the action of the spring 7 to fix the wire on the inner wall of the cylinder 4. When the wire is pulled by an external force and tends to move to the left, the friction force on the surface of the wire drives the baffle 6 to tend to rotate in the opposite direction. However, the baffle 6 cannot complete the reverse rotation due to the obstruction of the groove 5, so that the wire cannot be pulled out, thereby achieving the effect of preventing the wire from falling off.

[0034] This device has the effect of quick installation and disassembly, specifically:

[0035] A connecting structure is provided on the upper surface of the shell 1, and a card block 9 and a knob 10 are provided on the connecting structure to connect the shell 1 and the box cover 2, which is simple, quick and convenient to disassemble. The connecting structure includes a card slot 8, which is provided on the upper surface of the shell 1, and a card block 9 is rotatably installed on the inner wall of the card slot 8. The rotating shaft of the card block 9 passes through the side surface of the shell 1 and is connected with the knob 10. The card block 9 is J-shaped, and a card block 2 11 is provided on the lower surface of the box cover 2. The card block 2 11 is J-shaped in the opposite direction to the card block 1 9. The inner wall of the card slot 8 is slidably connected with a slider 12, which is located on one side of the card block 1 9, and a spring 7 is provided on the surface of the slider 12 to connect with the inner wall of the card slot 8;

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when installing the device, the inside of the device is connected or repaired from the top of the open shell 1. After the connection is completed, the box cover 2 is held and rotated to align the block 2 11 on the lower surface of the box cover 2 with the slot 8 on the surface of the shell 1. The knob 10 is held and rotated. The rotation of the knob 10 drives the block 1 9 to rotate on the inner wall of the slot 8. The rotating block 1 9 pushes the slider 12 to one side to move. The slider 12 slides in the slot 8 and compresses the spring 7 at the same time. The box cover 2 is rotated to fit with the upper surface of the shell 1. At this time, the block 2 11 is completely located in the slot 8. The knob 10 is rotated in the opposite direction to drive the block 1 9 to rotate in the opposite direction and engage with the block 2 11, so that the box cover 2 and the shell 1 are locked. At the same time, the slider 12 rebounds under the action of the spring 7, which restricts the block 1 9 and prevents the block 1 9 from separating from the block 2 11.

[0037] The device has the effect of sufficient heat dissipation, specifically:

[0038] A heat dissipation structure is provided on the bottom surface of the housing 1. The heat dissipation structure utilizes heat dissipation holes 13 and heat dissipation fans 14 to fully dissipate heat from the device. The circuit board 3 and the bottom surface of the housing 1 are mounted by a bracket, and the circuit board 3 and the bottom surface of the housing 1 are not in contact. The heat dissipation structure includes heat dissipation holes 13. The heat dissipation holes 13 are a group of long strip-shaped through holes. The heat dissipation holes 13 are provided on the bottom surface of the housing 1. The heat dissipation holes 13 are located directly below the circuit board 3. A heat dissipation fan 14 is provided through the bottom surface of the housing 1.

[0039] like Figure 2 and Figure 3 As shown, the circuit board 3 is mounted on the bottom surface of the housing 1 and has no contact with the heat dissipation holes 13 below, so that after the air enters from the heat dissipation holes 13, it can more fully contact the surface of the circuit board 3, so that the device can dissipate heat better. When the external temperature is too high, starting the cooling fan 14 can further dissipate heat for the device.

[0040] Working principle: When using the LED driving power supply for preventing the wires from falling off, a cylinder 4 is arranged on the side surface of the shell 1, and a baffle 6 is arranged inside the cylinder 4. The baffle 6 forms a barb structure inside the cylinder 4, so that the wire can only move in one direction during the process of passing through the cylinder 4, thereby achieving the effect of preventing the wires from falling off. The card block 1 9 on the upper surface of the shell 1 and the card block 2 11 on the surface of the box cover 2 are engaged and connected, so that the device can be quickly installed and disassembled, the circuit board 3 is mounted on the bottom surface of the shell 1, and the bottom surface of the shell 1 is provided with heat dissipation holes 13 and a heat dissipation fan 14, which can fully dissipate the heat inside the device, prevent the device from overheating during use, and increase the overall practicality.
