[0006] Preferably, the moving mechanism includes guide rods fixedly installed on both sides of the protection plate. One end of each guide rod is slidably connected to the frame body. A first spring is sleeved on the surface of each guide rod. When the protection plate is moved out of the frame body, the first spring is in a stretched or compressed state.

Connecting rods are slidably connected to both sides of each sliding seat. Limit blocks are fixedly connected to the ends of the connecting rods.

Detailed Description of the Embodiment

[0017] The following further elaborates on the present application Figures 1-4 in conjunction with the accompanying drawings.

[0018] The embodiment of the present application discloses an electric control box heat dissipation device, including a box body 1. A heat dissipation port is provided on the surface of the box body 1, and a frame body 2 is fixedly installed at the heat dissipation port. Slots 6 are provided on both sides of the frame body 2. A heat dissipation mechanism and a protection plate 3 are arranged on the frame body 2. A moving mechanism is arranged between the protection plate 3 and the frame body 2. Both the heat dissipation mechanism and the protection plate 3 can be moved into or out of the frame body 2 from the slots 6. When the heat dissipation mechanism is moved out of the frame body 2, the moving mechanism drives the protection plate 3 to move into the interior of the frame body 2 to block the heat dissipation port.

[0019] Furthermore, the moving mechanism includes guide rods 4 fixedly installed on both sides of the protection plate 3. One end of each guide rod 4 is slidably connected to the frame body 2. A first spring 5 is sleeved on the surface of the guide rod 4. When the protection plate 3 is moved out of the frame body 2, the first spring 5 is in a stretched or compressed state.

[0020] Further, the heat dissipation mechanism includes a heat dissipation frame 7. A filter screen 8 is fixedly installed inside the heat dissipation frame 7. An installation mechanism is provided on the heat dissipation frame 7 for installing the heat dissipation frame 7 on the frame body 2.

[0021] Further, the installation mechanism includes a sliding seat 9 fixedly installed on the surface of the heat dissipation frame 7. Connecting rods 12 are slidably connected to both sides of the sliding seat 9. Limit blocks 10 are fixedly connected to the ends of the connecting rods 12. And limit baffles 13 are fixedly connected to both sides of the frame body 2. The limit baffles 13 are arranged in an inverted L shape.

[0022] Further, second springs 11 are sleeved on the surfaces of the connecting rods 12. One end of each second spring 11 is connected to the limit block 10, and the other end of each second spring 11 is fixedly connected to the sliding seat 9.

[0023] In this embodiment, when the heat dissipation mechanism is inserted into the frame body 2 through the slot 6, the heat dissipation mechanism will push the protection plate 3 out of the slot 6 on the other side. The guide rods 4 and the first spring 5 on the protection plate 3 will also move accordingly. And in this embodiment, the first spring 5 is located between the protection plate 3 and the frame body 2, and the first spring 5 will be stretched. And after the heat dissipation mechanism is inserted into the frame body 2, move the limit block 10 so that the limit block 10 moves into the limit baffle 13. The provided second spring 11 can be used to tightly press against the limit baffle 13, so that the limit block 10 is stably embedded inside the limit baffle 13, thereby fixing the position of the heat dissipation mechanism.

[0024] In this embodiment, when removing the heat dissipation mechanism, only need to move the two limit blocks 10 out of the limit baffle 13, and then pull out the heat dissipation mechanism from the slot 6. During the process of pulling out the heat dissipation mechanism, the first spring 5 gradually resets, driving the protection plate 3 to move into the frame body 2, so as to block the heat dissipation port and prevent dust from entering the inside of the box body 1.
