Technical Field
[0001] The utility model belongs to the technical field of circuit breaker switches, and more specifically relates to an energy storage spring component of a circuit breaker switch. Background Art
[0002] Energy storage springs are energy storage mechanisms that utilize the expansion and contraction of a spring to store and release energy. They offer advantages such as a simple structure, short energy storage and release times, high efficiency, and low cost. They are widely used in various fields, particularly circuit breakers. Existing circuit breakers typically utilize a spring energy storage mechanism to achieve the closing operation of the circuit breaker. To ensure sufficient driving force for the closing operation, the energy storage spring assembly utilizes a high-elasticity spring. However, the energy storage springs are relatively long, requiring significant space when assembled on the circuit breaker. Furthermore, the high force and the fact that they are grouped together make assembly difficult, requiring specialized assembly tools. Consequently, improvements to the energy storage mechanisms of existing circuit breakers are needed.
[0003] In the prior art, there is a technology named "Energy Storage Structure of Indoor High-Voltage AC Vacuum Circuit Breaker" and the publication number is "CN201408706Y". This technology relates to the energy storage structure of indoor high-voltage AC vacuum circuit breaker, which drives the small gear to rotate through the output shaft of the power component, and the small gear rotates to drive the large gear to rotate, and the large gear rotates to extend the first energy storage spring and the second energy storage spring. When the first and second energy storage springs are stretched past the dead point, the large and small gears are automatically disengaged through the tripping eccentric shaft, and the energy storage latch supports the connecting bearing, so that the energy of the first and second energy storage springs can be maintained. At the same time, the fork rotates to cause the micro switch to cut off the energy storage power supply and complete the energy storage action. The purpose of the utility model is to overcome the above shortcomings and provide an indoor high-voltage AC vacuum circuit breaker with an ingenious energy storage structure design, short energy storage time, small force required for energy storage, time-saving and labor-saving, and easy to use. However, this technology does not involve the technical problems and technical solutions of the present application. Utility Model Content
[0004] The technical problem to be solved by the utility model is: to address the deficiencies of the existing technology, to provide a circuit breaker switch energy storage spring component with a simple structure, which reduces the length of the energy storage spring and occupies less space while meeting the energy storage requirements, is easy to install and saves labor, and reduces the difficulty of assembly.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is:
[0006] The utility model discloses an energy storage spring component for a circuit breaker switch. The upper part of the energy storage spring is connected to an upper hanging plate, the lower end of the energy storage spring is connected to a lower hanging plate, the upper hanging plate is connected to an assembly seat through an upper connecting pin, the assembly seat is connected to the top of a frame through an adjusting bolt, and the lower hanging plate is connected to a crank arm through a lower connecting pin.
[0007] The upper hanging plate is provided with a plurality of upper connecting holes for the energy storage springs, and the lower hanging plate is provided with a plurality of lower connecting holes for the energy storage springs.
[0008] The energy storage spring is a coil spring.
[0009] The upper end of the energy storage spring passes through a plurality of upper connection holes of the energy storage spring, and the lower end of the energy storage spring passes through a plurality of lower connection holes of the energy storage spring.
[0010] The upper hanging plate further includes an upper limit surface, and the lower hanging plate further includes a lower limit surface.
[0011] The assembly seat comprises an assembly seat connecting portion and an assembly seat hinge portion. The assembly seat connecting portion is connected to the frame top through a plurality of adjustment bolts, and the assembly seat hinge portion is connected to the upper hanging plate through an upper connecting pin.
[0012] The assembly seat, upper hanging plate and lower hanging plate are all structures made of metal materials.
[0013] The length of the energy storage spring in an uncompressed state is smaller than the distance between the upper hanging plate and the lower hanging plate.
[0014] The technical solution of this utility model is adopted, and the working principle and beneficial effects are as follows:
[0015] The energy storage spring component of the circuit breaker switch described in the present invention is structured to form an energy storage spring. The upper portion of the energy storage spring is connected to an upper hanging plate, which is connected to the energy storage spring on one hand and to an assembly seat on the other hand. The lower end of the energy storage spring is connected to a lower hanging plate, which is connected to the energy storage spring on one hand and to a crank arm on the other hand, thereby achieving a reliable connection of the energy storage spring. The upper hanging plate is connected to the assembly seat via an upper connecting pin, the assembly seat is connected to the top of the frame via an adjusting bolt, and the lower hanging plate is connected to the crank arm via a lower connecting pin. Because the length of the energy storage spring in the uncompressed state is less than the distance between the upper hanging plate and the lower hanging plate, during assembly, the energy storage spring is first connected to the upper hanging plate and the lower hanging plate, then the upper hanging plate is connected to the assembly seat, and the lower hanging plate is connected to the crank arm. At this time, the assembly seat is still a distance from the top of the frame. To this end, the top of the frame and the assembly seat are connected by adjusting bolts. The adjusting bolts are passed through the threaded holes on the assembly seat at the top of the frame and then screwed. The adjusting bolts are then turned, and the adjusting bolts apply force to the assembly seat, driving the assembly seat to move toward the top of the frame until it fits against the lower surface of the top of the frame to complete the connection. In this way, the installation is simpler and more labor-saving, and no special tools are needed for assembly, which is convenient for assembly and improves work efficiency. The length of the energy storage spring can be shortened, and the height space occupied by it during installation is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is a detailed description of the embodiments of the present invention, such as the shapes, structures, positions and connections of the various components involved, the functions and working principles of the various components, etc., by referring to the accompanying drawings.
[0021] As attached Figure 1 , Attachment Figure 2As shown, the utility model is a circuit breaker switch energy storage spring component. The upper portion of the energy storage spring 4 is connected to the upper hanging plate 3, and the lower end of the energy storage spring 4 is connected to the lower hanging plate 5. The upper hanging plate 3 is connected to the assembly base 1 via an upper connecting pin 2. The assembly base 1 is connected to the frame top 8 via an adjusting bolt 7. The lower hanging plate 5 is connected to the crank arm 6 via a lower connecting pin. The length of the energy storage spring 4 in its uncompressed state is less than the distance between the upper hanging plate 3 and the lower hanging plate 5. The above structure provides an improved technical solution to address the shortcomings of the existing technology. When setting up the structure, the energy storage spring 4 is manufactured, with the upper portion of the energy storage spring 4 connected to the upper hanging plate 3. The upper hanging plate 3 is connected to the energy storage spring 4 on one side and to the assembly base 1 on the other side. The lower end of the energy storage spring 4 is connected to the lower hanging plate 5 on one side and to the crank arm 6 on the other side, thereby achieving a reliable connection of the energy storage spring 4. The upper hanging plate 3 is connected to the assembly base 1 via an upper connecting pin 2. The assembly base 1 is connected to the frame top 8 via an adjusting bolt 7. The lower hanging plate 5 is connected to the crank arm 6 via a lower connecting pin. Because the length of the energy storage spring 4 in the uncompressed state is less than the distance from the upper hanging plate 3 to the lower hanging plate 5, when assembling, first connect the energy storage spring 4 to the upper hanging plate 3 and the lower hanging plate 5, then connect the upper hanging plate 3 to the assembly seat 1, and connect the lower hanging plate 5 to the crank arm 6. At this time, the assembly seat 1 is still a distance away from the frame top 8. For this reason, the frame top 8 and the assembly seat 1 are connected by adjusting bolts 7. The adjusting bolts 7 pass through the frame top 8 and are screwed into the threaded holes on the assembly seat 1 to connect them. Then, the adjusting bolts 7 are screwed. The adjusting bolts 7 are applied to the assembly seat 1, driving the assembly seat 1 to move toward the frame top 8 until it is fitted on the lower surface of the frame top 8 to complete the connection. In this way, on the one hand, the entire installation is simpler and more labor-saving, and does not require special tools to assemble. It is easy to assemble and provides work efficiency. On the other hand, the length of the energy storage spring can be shortened so that the height space occupied during its installation is greatly reduced. The circuit breaker switch energy storage spring component described in the utility model has a simple structure. Under the premise of meeting the energy storage requirements, the energy storage spring length is reduced, the space occupied is large, and the installation is convenient and labor-saving, reducing the difficulty of assembly.
[0022] The upper hanging plate 3 is provided with multiple upper connection holes 9 for the energy storage springs, and the lower hanging plate 5 is provided with multiple lower connection holes 10 for the energy storage springs. The upper end of the energy storage spring 4 passes through the multiple upper connection holes 9, and the lower end of the energy storage spring 4 passes through the multiple lower connection holes 10. This structure facilitates the corresponding connection between the upper and lower parts of the energy storage springs, ensuring that the energy storage springs only move in a telescopic manner during use and will not easily fall over or fall off.
[0023] The energy storage spring 4 is a coil spring. The upper plate 3 also includes an upper limit surface 11, and the lower plate 5 also includes a lower limit surface 12. The upper limit surface 11 abuts the upper end of the energy storage spring 4, and the lower limit surface abuts the lower end of the energy storage spring 4, defining the upper and lower positions of the energy storage springs.
[0024] The assembly base 1 comprises an assembly base connection portion 13 and an assembly base hinge portion 14. The assembly base connection portion 13 is connected to the frame top 8 via a plurality of adjustment bolts 7, and the assembly base hinge portion 14 is connected to the upper hanging plate 3 via an upper connecting pin 2. With this structure, the upper hanging plate is conveniently and reliably connected to the assembly base via the upper connecting pin, ensuring that the two form a movable hinge structure and are unlikely to fall off easily.
[0025] The assembly seat 1, the upper hanging plate 3 and the lower hanging plate 5 are all structures made of metal materials.
[0026] The energy storage spring component of the circuit breaker switch described in the present invention is constructed by manufacturing an energy storage spring 4. The upper portion of the energy storage spring 4 is connected to an upper hanging plate 3. The upper hanging plate 3 is connected to the energy storage spring 4 on one hand, and to the assembly base 1 on the other hand. The lower end of the energy storage spring 4 is connected to a lower hanging plate 5. The lower hanging plate is connected to the energy storage spring 4 on one hand, and to the crank arm 6 on the other hand, thereby achieving a reliable connection of the energy storage spring 4. The upper hanging plate 3 is connected to the assembly base 1 via an upper connecting pin 2. The assembly base 1 is connected to the frame top 8 via an adjusting bolt 7. The lower hanging plate 5 is connected to the crank arm 6 via a lower connecting pin. Because the length of the energy storage spring 4 in the uncompressed state is less than the distance from the upper hanging plate 3 to the lower hanging plate 5, when assembling, first the energy storage spring 4 is connected to the upper hanging plate 3 and the lower hanging plate 5, then the upper hanging plate 3 is connected to the assembly seat 1, and the lower hanging plate 5 is connected to the crank arm 6. At this time, the assembly seat 1 is still a distance away from the frame top 8. For this reason, the frame top 8 and the assembly seat 1 are connected by adjusting bolts 7. The adjusting bolts 7 pass through the frame top 8 and are screwed to connect the threaded holes on the assembly seat 1. Then, the adjusting bolts 7 are screwed. The adjusting bolts 7 are applied on the assembly seat 1, driving the assembly seat 1 to move toward the frame top 8 until it is fitted on the lower surfaces of the frame top 8 and connected. In this way, on the one hand, the energy storage spring is installed more simply and labor-savingly, does not need to borrow special tools to assemble, is easy to assemble, and provides work efficiency. On the other hand, the length of the energy storage spring can be shortened, so that the height space occupied during its installation is greatly reduced.
