Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, and more specifically, to an energy storage component for an energy storage operating mechanism. Background Technology

[0002] Most circuit breakers on the market use electric operating mechanisms that can be controlled remotely, and their opening or closing time is about 1 second, which cannot meet the needs of situations where a closing operation is required after receiving a closing command. Therefore, there is a need for an operating mechanism that can reduce the closing operation time.

[0003] According to Chinese Patent CN202323422802.5, an energy storage lever assembly for a frame-type circuit breaker operating mechanism includes an energy storage lever, an energy storage spring seat that is linked to the energy storage lever, and an energy storage spring. One end of the energy storage spring seat has a spring seat body that cooperates with the drive shaft of the energy storage lever. The spring seat body is provided with an arc-shaped positioning groove that cooperates with the drive shaft. The drive shaft abuts against the arc-shaped positioning groove, forming a linkage between the energy storage spring seat and the drive shaft. The other end of the energy storage spring seat has a guide rod that cooperates with the energy storage spring. The energy storage spring is fitted onto the guide rod, with one end of the energy storage spring abutting against the spring seat body and the other end abutting against the mechanism frame of the operating mechanism. This assembly has the advantages of simple structure, stable and reliable performance, reliable transmission, convenient assembly, and low cost. Existing energy storage lever assemblies lack a limiting mechanism between the energy storage spring seat and the drive shaft, resulting in an unreliable connection, easy detachment, and low safety.

[0023] According to an embodiment of the present invention, an energy storage component for an energy storage operating mechanism is provided.

[0024] Example 1;

[0025] like Figure 1-5As shown, the energy storage component for an energy storage operating mechanism according to an embodiment of the present invention includes an energy storage frame 1, a drive shaft 2 in the energy storage frame 1, a spring seat 3 on the outer wall of the drive shaft 2, an arc-shaped groove 4 matching the drive shaft 2 on one side of the spring seat 3, the spring seat 3 being connected to the drive shaft 2 via a connecting component, a guide rod 5 on the side of the spring seat 3 away from the drive shaft 2, an energy storage spring 6 sleeved on the outer wall of the guide rod 5, one side of the energy storage spring 6 being connected to the spring seat 3, and the side of the energy storage spring 6 away from the spring seat 3 being connected to the mechanism frame of the external operating mechanism.

[0026] Example 2;

[0027] like Figure 1-5As shown, the device includes an energy storage rack 1, a drive shaft 2 within the energy storage rack 1, and a spring seat 3 on the outer wall of the drive shaft 2. One side of the spring seat 3 has an arc-shaped groove 4 that matches the drive shaft 2. The spring seat 3 is connected to the drive shaft 2 via a connecting assembly. A guide rod 5 is located on the side of the spring seat 3 away from the drive shaft 2. An energy storage spring 6 is fitted onto the outer wall of the guide rod 5. One side of the energy storage spring 6 is connected to the spring seat 3, and the side of the energy storage spring 6 away from the spring seat 3 is connected to the frame of an external operating mechanism. Several evenly distributed limiting blocks 7 are located on one side of the spring seat 3 near the guide rod 5. The connecting assembly includes a positioning post 8 on the outer wall of the drive shaft 2, a positioning groove 9 on the spring seat 3 that matches the positioning post 8, an installation groove 10 in the positioning post 8, a fixing block 11 in the installation groove 10, limiting slide rods 12 on both sides of the fixing block 11, a sliding groove 13 on one side of the limiting slide rod 12, a matching slider 14 in the sliding groove 13, a guide slide rod 15 extending out of the sliding groove 13 and connected to the fixing block 11 on one side of the slider 14, a return spring 16 sleeved on one side of the limiting slide rod 12 and on the outer wall of the guide slide rod 15, the side of the limiting slide rod 12 away from the fixing block 11 extending out of the positioning post 8, and a limiting groove 17 on the spring seat 3 that matches the limiting slide rod 12. The sliding groove 13 is a rectangular groove, and the slider 14 is a rectangular block. The drive shaft 2 has an adjustment groove 18 that communicates with the mounting groove 10. A pressing plate 19 is provided in the adjustment groove 18. The pressing plate 19 is connected to the fixing block 11 via a second return spring 20. A pressing rod 21 is symmetrically arranged on one side of the pressing plate 19 located near the second return spring 20. A guide groove 22 matching the pressing rod 21 is provided on the outer wall of the limiting slide rod 12. One side of the pressing plate 19 extends outside the drive shaft 2.

[0028] In practical applications, when connecting the spring seat 3 to the drive shaft 2, the operator first presses the pressing plate 19. The pressing plate 19 drives the pressing rod 21 to press the guide groove 22 on the limiting slide rod 12. At this time, the second reset spring 20 is in a compressed state. The limiting slide rod 12 is compressed and begins to move towards the side of the fixed block 11 on the guide slide rod 15, compressing the first reset spring 16, until the side of the guide slide rod 15 away from the fixed block 11 enters the inner wall of the mounting groove 10. At this time, the arc-shaped groove 4 on the spring seat 3 is fitted with the outer wall of the drive shaft 2, and the positioning pin 8 on the drive shaft 2 is inserted into the positioning groove 9 on the spring seat 3. When the pressing plate 19 is released, the second reset spring 20 resets and moves the pressing plate 19. The pressing plate 19 moves the pressing rod 21 away from the guide slide 22. At this time, the first reset spring 16 resets and moves the limiting slide rod 12 until one side of the limiting slide rod 12 moves out of the mounting groove 10 and inserts into the limiting groove 17 on the spring seat 3 to connect and fix it. By setting the connecting component, the drive shaft on the energy storage rack is more securely installed with the spring seat, preventing the drive shaft from separating from the spring seat during operation and improving safety. At the same time, the connecting component makes it easier to disassemble and assemble the spring seat and the drive shaft, and it is easy to replace the spring seat when it is damaged.

[0029] In summary, by using the above-mentioned technical solution of this utility model, the drive shaft on the energy storage rack and the spring seat are more securely installed by setting the connecting component, preventing the drive shaft from separating from the spring seat during operation and improving safety. At the same time, the connecting component makes it easier to disassemble and assemble the spring seat and the drive shaft, and facilitates replacement when the spring seat is damaged.
