[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1:

[0021] Please refer to Figures 1-4 The utility model provides a technical solution: an electric control box for an air conditioner, comprising a box body 1 and a box cover 2. A circuit board 3 is provided inside the box body 1. Rods 5 are fixedly connected to the four corners of the bottom of the box cover 2. The outer surfaces of the left and right sides of the box body 1 are fixedly connected to a fixed frame 4. A movable rod 6 is movably inserted into the outer surface of the bottom end of the rod 5. A disk is fixedly connected to the outer surface of the movable rod 6 close to the box body 1. A first spring 7 is fixedly connected between the disk and the rod 5. The first spring 7 is sleeved on the outer surface of the movable rod 6. A triangular block 8 is fixedly connected to the end of the movable rod 6 away from the disk. Specifically, the wire is connected to the circuit board 3. When the box cover 2 needs to be closed, the rods 5 at the bottom of the box cover 2 are respectively inserted into the outer surface of the movable rod 6. In the fixed frame 4, when the triangular block 8 contacts the top of the fixed frame 4, the fixed frame 4 is squeezed by the downward extrusion force, causing the triangular block 8 to be squeezed by the fixed frame 4, causing the first spring 7 to deform until the triangular block 8 enters the fixed frame 4. When the triangular block 8 moves to the bottom of the fixed frame 4, the first spring 7 is reset, and the first spring 7 drives the triangular block 8 to make the triangular block 8 contact with the bottom of the fixed frame 4, so that the box cover 2 and the box body 1 are clamped together by the triangular block 8 being clamped at the bottom of the fixed frame 4, thereby completing the connection between the box cover 2 and the box body 1. When the box cover 2 needs to be removed, it is only necessary to push the triangular block 8, which facilitates the assembly of the box body 1 and the box cover 2, and facilitates opening the box body 1 to inspect the circuits and parts inside it.

[0022] In this embodiment, the bottom outer surface of the box cover 2 is fixedly connected to a connecting block 9, and the connecting block 9 is fixedly connected to two vertical plates arranged symmetrically in front and back on the side opposite to the interior of the box body 1. The outer surfaces of the two vertical plates are rotatably connected to the positive and negative screw rods 10, and the positive and negative screw rods 10 rotate and penetrate the front vertical plate. The front outer surface of the positive and negative screw rods 10 is fixedly connected to a knob 13. The outer surface of the positive and negative screw rods 10 is threadedly connected to two threaded blocks 11. A fixed block 12 is rotatably sleeved at the center of the positive and negative screw rods 10. The outer surfaces of the upper and lower threaded blocks 11 and the fixed blocks are connected to the opposite surfaces. The outer surfaces relative to each other of 12 are fixedly connected with a connecting seat 14, and an arc-shaped clamping plate 15 is provided inside the connecting seat 14. Specifically, the position of the arc-shaped clamping plate 15 can be adjusted according to the actual interface position of the wires. At this time, the knob 13 is turned, and the knob 13 drives the positive and negative screw rods 10 to rotate, and the positive and negative screw rods 10 drive the threaded block 11 to move, so that the connecting seats 14 on both sides move, thereby adjusting the distance between the three connecting seats 14, so that the position of the arc-shaped clamping plate 15 can be adjusted according to the actual interface position of the wire, avoiding large bending of the wire that affects the life of the wire.

[0023] In this embodiment, a plurality of second springs 16 are fixedly connected to the outer surface of the connecting seat 14, and the other end of the second spring 16 is fixedly connected to the arc-shaped clamping plate 15. Specifically, under the elastic force of the second spring 16, the distance between the two arc-shaped clamping plates 15 can be changed, thereby being able to change according to the diameter of the wire, so that the arc-shaped clamping plate 15 elastically clamps the wire.

[0024] In this embodiment, a third spring 17 is fixedly connected to the top outer surface of the fixed frame 4, and an extension block 18 is fixedly sleeved on the outer surface of the insertion rod 5. Specifically, when the insertion rod 5 is inserted into the fixed frame 4, the extension block 18 squeezes the third spring 17.

[0025] In this embodiment, the diameter of the third spring 17 is larger than the diameter of the insertion rod 5, and one end of the extension block 18 extends to the outside of the third spring 17. Specifically, the diameter of the third spring 17 is larger than the diameter of the insertion rod 5, so that the insertion rod 5 passes through the third spring 17 and is inserted into the fixed frame 4. When the extension block 18 contacts the third spring 17, as force is applied to the insertion rod 5, the third spring 17 is compressed. When the triangular block 8 contacts the bottom of the fixed frame 4, under the action of the elastic force of the third spring 17, the triangular block 8 is driven to fit tightly against the bottom of the fixed frame 4.

[0026] In this embodiment, multiple threaded blocks 11 are movably fitted with the bottom inner surface of the box body 1 and the bottom outer surface of the connecting block 9, respectively, and two fixed blocks 12 are fixedly connected to the bottom inner surface of the box body 1 and the bottom outer surface of the connecting block 9, respectively. Specifically, when the forward and reverse screw rods 10 rotate, the threaded blocks 11 are driven to slide at the corresponding box body 1 or connecting block 9, and the two fixed blocks 12 are fixed to the box body 1 and the connecting block 9 to prevent the fixed blocks 12 from moving.

[0027] When the box cover 2 is installed, the arc-shaped splint 15 at the bottom of the box cover 2 cooperates with the arc-shaped splint 15 inside the box body 1 to clamp the wire. When the box cover 2 needs to be removed, it is only necessary to push the triangular block 8, which facilitates the assembly of the box body 1 and the box cover 2, and facilitates the box body 1 to be opened for inspection and maintenance of the circuit board and parts inside.

[0028] According to the actual interface position of the wires, the position of the arc splint 15 can be adjusted. At this time, the knob 13 is turned, and the knob 13 drives the forward and reverse screw rods 10 to rotate, and the forward and reverse screw rods 10 drive the threaded block 11 to move, so that the connecting seats 14 on both sides move, thereby adjusting the distance between the three connecting seats 14, so that the position of the arc splint 15 can be adjusted according to the actual interface position of the wires, avoiding large bending of the wires that affects the life of the wires.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
