[0033] In this embodiment, the contact box 1 plays the role of connecting, protecting, distributing electric energy and providing insulation protection. The positioning box 2 plays the role of supporting and fixing the contact box 1. The mounting plate 3 and the connecting plate 5 can be bolted together through the mounting screw holes 4, so as to fix the contact box 1 and the positioning box 2. The fixing plate 6 on the connecting plate 5 plays the role of providing an installation space. The heat sink 25 can disperse the heat generated by the contact box 1 during operation, so that the operating temperature of the contact box 1 remains normal and no high temperature danger occurs.

[0034] A protection component is arranged on the fixing plate 6 and is used to provide external protection for the combination switch to prevent accidental damage;

[0035] The locking assembly is arranged on the fixing plate 6 and is used to adjust and lock the gear position of the combination switch to prevent the influence caused by accidental touch.

[0036] Embodiment 2:

[0037] On the basis of the first embodiment, this embodiment describes one of the implementable structures of the protection component, the protection component includes a fixed base 7 fixedly arranged on the fixed plate 6, a fixed rod 8 is symmetrically fixedly arranged on the fixed base 7, the fixed rod 8 is hollow, a sliding rod 9 is slidably arranged in the fixed rod 8, a card slot 10 is opened on the fixed rod 8, a card block 11 is fixedly arranged on the sliding rod 9, the number and position of the card slot 10 and the card block 11 are correspondingly arranged, a protective cover 12 is fixedly arranged on the top of the sliding rod 9, the protective cover 12 is slidably arranged on the fixed plate 6, the protective cover 12 is made of a transparent plastic material, and a handle 24 is fixedly arranged on the protective cover 12;

[0038] In this embodiment, the fixed base 7 plays a role in supporting the fixed rod 8. There are two fixed rods 8, which are hollow and have a sliding rod 9 sliding inside. The sliding rod 9 can slide inside the fixed rod 8, thereby driving the protective cover 12 fixedly connected to the top of the sliding rod 9 to move. The protective cover 12 is made of transparent material, which is convenient for operators to observe. The plastic material saves resources and has a good protective effect. The card slot 10 and the card block 11 can cooperate to fix the protective cover 12 on the sliding rod 9, which is convenient for operators to operate. At the same time, the card block 11 can be pressed back into the sliding rod 9 by pulling the handle 24, thereby driving the sliding rod 9 to move and realizing the closing switch of the protective cover 12.

[0039] Embodiment three:

[0040] On the basis of the first embodiment, this embodiment describes one of the implementable structures of the locking assembly, the locking assembly includes a positioning plate 13 fixedly arranged on the fixed plate 6, a plurality of positioning grooves 14 are provided on the positioning plate 13, a rotating handle 15 is rotatably provided on the positioning plate 13, a fixed block 16 is fixedly provided on the rotating handle 15, a fixed groove 17 is provided in the fixed block 16, a second clamping block 18 is fixedly provided in the fixed groove 17, a locking block 19 is slidably provided in the fixed groove 17, a first limiting groove 20 and a second limiting groove 21 are provided on the locking block 19, a limiting block 22 is fixedly provided on the locking block 19, a limiting plate 23 is fixedly provided on the rotating handle 15, and anti-slip patterns are provided on the rotating handle 15 and the locking block 19;

[0041] In this embodiment, the positioning disk 13 is used to position and lock the rotating handle 15. Scales can also be added to the positioning disk 13 for marking. Positioning grooves 14 are equidistantly provided on the circumference of the positioning disk 13, which can be matched and set according to the scale requirements. The positioning grooves 14 correspond to the locking blocks 19. The locking blocks 19 can be inserted into the positioning grooves 14 for fixing. The rotating handle 15 can drive the contact box 1 to rotate. The fixing block 16 can fix and support the locking block 19. When the locking block 19 is inserted into the positioning groove 14 for fixing, the second clamping block 18 in the fixing groove 17 cooperates with the first limiting groove 20 to further fix the locking block 19 to prevent the rotating handle 15 from being accidentally touched.

[0042] When the rotating handle 15 needs to be rotated, the locking block 19 is taken out from the positioning groove 14, so that the second clamping block 18 cooperates with the second limiting groove 21, and the limiting block 22 and the limiting plate 23 are used to limit the locking block 19. The locking block 19 is fixed in the fixing groove 17 so that the rotating handle 15 can be rotated. The anti-slip grooves can increase friction and improve the controllability of the device.

[0043] The contact box 1, the positioning box 2 and the heat sink 25 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art, and the specifications and models of the contact box 1, the positioning box 2 and the heat sink 25 are well known to those skilled in the art and will not be described in detail here.

[0044] Working principle: Before using the frequency conversion cabinet combination switch, pull the handle 24 to drive the protective cover 12 to move, clamp the block 11 on the sliding rod 9 with the slot 10 on the fixed rod 8, so that the protective cover 12 can be fixed above the rotating handle 15;

[0045] During the use of the frequency conversion cabinet combination switch, the contact box 1 can be driven to rotate by rotating the rotating handle 15, so as to complete the switching and opening and closing between the contacts. When the rotating handle 15 is working, the rotating handle 15 can be fixed and locked by inserting the locking block 19 into the positioning groove 14 on the positioning plate 13 to prevent accidental touch from affecting the use of the combination switch. At the same time, the fixing block 16 can fix the locking block 19, and the second clamping block 18 in the fixing groove 17 cooperates with the first limiting groove 20 to further fix the locking block 19 in the fixing block 16, so that the effect of preventing accidental touch is better.

[0046] When the rotating handle 15 needs to be rotated, the locking block 19 is lifted up to make the second clamping block 18 cooperate with the second limiting groove 21. At this time, the bottom surface of the locking block 19 is flush with the bottom surface of the fixing block 16. The limiting block 22 and the limiting plate 23 can prevent the locking block 19 from sliding out of the fixing block 16, and then the rotating handle 15 can be rotated;

[0047] When the combination switch is not needed temporarily, the handle 24 can be pulled to move the protective cover 12 downward to protect the exterior of the combination switch, thereby preventing accidental damage and increasing the service life of the device.

[0048] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
