[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment: As Figures 1-6 shown, the present invention provides a contactor switch structure, including a contactor switch 1. A push rod 11 is arranged on one side of the contactor switch 1. A side plate 12 is fixedly installed on the side of the contactor switch 1 away from the push rod 11. A protective frame 13 is arranged on the side of the side plate 12 close to the contactor switch 1. An insulating plate 2 is arranged outside the push rod 11. The insulating plate 2 is arc-shaped, so that the insulating plate 2 fits better with the push rod 11, and it is more convenient to pull the push rod 11 downward. A connecting plate 21 is fixedly installed at the top end of the insulating plate 2. Two symmetrically distributed connecting blocks 22 are fixedly installed on the side of the connecting plate 21 close to the protective frame 13. The connecting blocks 22 are fixed at the edge of the connecting plate 21. A connecting rod 23 is fixedly installed in the middle of the connecting block 22. Two symmetrically distributed first sleeves 24 are fixedly installed outside the connecting rod 23. The first sleeves 24 are located at the edge of the connecting rod 23. Arc-shaped grooves 25 for cooperating with the connecting rod 23 are respectively formed through both sides of the protective frame 13.

[0019] Two symmetrically distributed first fixing blocks 3 are fixedly installed on both sides of the side plate 12. A first clamping block 31 is fixedly installed on the side of the first fixing block 3 close to the protective frame 13. The first clamping block 31 is located at the edge of the first fixing block 3. Second fixing blocks 32 corresponding to the first fixing blocks 3 are fixedly installed at the edges of both sides of the protective frame 13. A first clamping groove 33 for cooperating with the first clamping block 31 is formed through the middle of the second fixing block 32.

[0020] A third fixing block 34 is fixedly installed at the top end of each second fixing block 32. Circular grooves 35 are respectively formed at the bottom of the third fixing block 34 and the top end of the second fixing block 32. A spring 36 is fixedly installed on the lower surface of the inner wall of the circular groove 35. A fixing column 37 is fixedly installed at the bottom end of the spring 36. A fixing groove 38 for cooperating with the fixing column 37 is formed through the middle of each first clamping block 31. A guide rod 39 is fixedly installed at the top end of the fixing column 37. The guide rod 39 is slidably clamped in the third fixing block 34. A handle 30 is rotatably sleeved at the top of the guide rod 39. The handle 30 is made of plastic material, which increases the comfort between the hand and the handle 30 and is more convenient to rotate the handle 30.

[0021] A second sleeve 4 is provided on the outside of each first sleeve 24. Second clamping blocks 41 are fixedly installed on both sides of the inner wall of the second sleeve 4. A sliding groove 42 for cooperating with the second clamping block 41 is formed on the outside of the first sleeve 24. Second clamping grooves 43 for cooperating with the second clamping block 41 are formed at positions of both sides of the protective frame 13 corresponding to the arc-shaped grooves 25. By providing the second sleeve 4, when the second sleeve 4 drives the second clamping block 41 to move in the sliding groove 42 towards the protective frame 13, the second clamping block 41 is clamped into the corresponding second clamping groove 43, thereby fixing the connecting rod 23 on the protective frame 13 and preventing the insulating plate 2 from affecting the pulling of the push rod 11 when the push rod 11 is pulled upwards. A rubber sleeve 44 is fixedly installed on the outside of the second sleeve 4. By providing the rubber sleeve 44, the comfort of the hand is increased, and it is more convenient to pull the connecting rod 23 through the second sleeve 4 and the first sleeve 24.

[0022] Limit blocks 5 are fixedly installed on both sides of each fixed column 37. First limit grooves 51 for cooperating with the limit blocks 5 are formed at the bottom of the third fixed block 34 and the top of the second fixed block 32. Second limit grooves 52 for cooperating with the limit blocks 5 are formed in the middle of each first clamping block 31 outside the fixed groove 38. By providing the limit blocks 5, the first limit grooves 51 and the second limit grooves 52, the fixed column 37 is more stable during the moving process.

[0023] A lid 6 is hinged to one side of the protective frame 13 away from the side plate 12. A handle 61 is fixedly installed on the side of the lid 6 away from the protective frame 13. By providing the lid 6, too much dust is prevented from entering the protective frame 13 and adhering to the contactor switch 1. At the same time, the lid 6 can be conveniently opened through the handle 61 to pull the push rod 11 upwards.

[0024] Working principle: During actual use, when it is necessary to pull the contactor switch 1, hold the rubber sleeves 44 on both sides to drive the second sleeve 4, the first sleeve 24, and the connecting rod 23 to slide in the arc-shaped groove 25. As the connecting rod 23 moves, the connecting block 22, the connecting plate 21, and the insulating plate 2 are driven to move downwards. Since the insulating plate 2 is in contact with the push rod 11, the insulating plate 2 drives the push rod 11 to move downwards. When the connecting rod 23 moves from one end of the arc-shaped groove 25 to the other end, it means that the push rod 11 has been completely pulled down and the contactor can be repaired. Thus, the person pulling the push rod 11 does not directly contact the push rod 11, avoiding the person being electrocuted.

[0025] When installing the protection frame 13 on the side plate 12, align the first card slot 33 with the first card block 31, and pass the first card block 31 through the first card slot 33. Then, turn the handle 30 in the direction away from the protection frame 13, driving the guide rod 39 and the fixing column 37 to move downward in the circular groove 35. At the same time, the spring 36 rebounds, causing the fixing column 37 to snap into the corresponding fixing slot 38. When the handle 30 and the third fixing block 34 form a "two" shape, it indicates that the fixing column 37 is completely snapped into the fixing slot 38. Thus, the protection frame 13 and the side plate 12 are fixed together through the second fixing block 32 and the side plate 12 through the first fixing block 3.

[0026] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
