Technical Field

[0001] This utility model relates to the technical field of spring cylinder guide structure for power distribution control equipment, specifically a spring cylinder guide flange for power distribution control equipment. Background Technology

[0002] The spring cylinder in power distribution control equipment is the core energy storage and transmission component of the spring operating mechanism. It is mainly used in the operating mechanism of high-voltage switchgear (such as circuit breakers and load switches) to achieve precise transmission of mechanical energy through the compression / release of the spring.

[0003] However, the existing power distribution control equipment spring cylinders lack a guiding structure, resulting in insufficient precision in the movement trajectory of the spring crankshaft and the problem of spring deviation during compression.

[0004] Therefore, it is particularly important to design a spring cylinder guide flange for power distribution control equipment to overcome the above-mentioned technical defects and improve the overall practicality. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A spring cylinder guide flange for power distribution control equipment includes an outer spring cylinder and an inner spring cylinder. A guide rod extending upwards is connected to the center of the bottom inner side of the inner spring cylinder. An adjusting screw is connected to one end of the guide rod, which passes through the top of the inner spring cylinder. A locking nut is threaded onto the outer side of the adjusting screw. A helical spring is installed inside the outer spring cylinder. Guide pillars are installed on both the left and right sides of the top edge of the outer spring cylinder. Guide wheel assemblies are installed at the top positions of both the left and right sides of the inner spring cylinder. Guide grooves are formed at the top of both the left and right sides inside the outer spring cylinder. Guide rails are installed inside the guide grooves, and guide slide blocks are slidably connected to the outer sides of the guide rails.

[0008] As a preferred embodiment of this utility model, the connection between the guide rod and the inner spring cylinder is a sliding connection.

[0009] As a preferred embodiment of this utility model, the bottom side of the locking nut is in contact with the top surface of the spring inner cylinder.

[0010] As a preferred embodiment of this utility model, the two ends of the helical spring are respectively fixedly connected to the outer spring cylinder and the inner spring cylinder by bolts.

[0011] As a preferred embodiment of this utility model, the connection between the guide rod and the guide wheel assembly is a sliding connection.

[0012] As a preferred embodiment of this utility model, the two sets of guide slides are respectively fixedly installed at the bottom positions on the left and right sides of the inner cylinder of the spring by bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this utility model, a spring cylinder guide flange for a power distribution control device is provided. Guide grooves are designed on both the left and right inner walls inside the outer spring cylinder. Under the guidance of the guide rail and guide slide, the sliding inner spring cylinder moves downward and the helical spring contracts. At the same time, during the downward movement of the inner spring cylinder, the sliding cooperation between the guide rod and the guide wheel assembly can help to achieve precise guidance and energy transfer of the helical spring, avoiding the problem of insufficient precision in the movement trajectory of the helical spring crankshaft and the deviation of the helical spring during compression.

Under the guiding action of the guide slide rails 10 and the guide slide blocks 11, the inner spring cylinder 2 is guided to move downward and the helical spring 6 is contracted. At the same time, during the downward movement of the inner spring cylinder 2, the sliding cooperation between the guide rods 7 and the guide wheel assemblies 8 can help to achieve precise guidance and energy transfer of the helical spring 6.

[0025] The guide rod 3 is connected to the inner spring cylinder 2 by a sliding connection. The bottom side of the locking nut 5 is connected to the top surface of the inner spring cylinder 2.
