The invention relates to a main-auxiliary spring assembly and a spring seat of the main-auxiliary spring assembly. The main-auxiliary spring assembly comprises the spring seat. The spring seat is connected with the free end of a main spring and the free end of an auxiliary spring. The spring seat comprises an auxiliary spring screwing connection column and a main spring seat, wherein the auxiliary spring screwing connection column is connected with the auxiliary spring, and the main spring seat is connected with the main spring. The upper end of the auxiliary spring screwing connection column is provided with an auxiliary spring spiral groove used for screwing in of a plurality of spiral spring circles of the lower end of the auxiliary spring. The lower end of the auxiliary spring screwing connection column is provided with a connecting structure used for connection with a corresponding force bearing object. The auxiliary spring screwing connection column is provided with a pushing structure exerting pushing force downwards. The main spring seat is provided with a stopping structure which stops the pushing structure in a matched manner. When the auxiliary spring screwing connection column pushes the main spring seat downwards, the auxiliary spring spiral groove is matched with the spring circles of the auxiliary spring in an up-and-down limitation manner all the time. According to the main-auxiliary spring assembly and the spring seat of the main-auxiliary spring assembly, the auxiliary spring screwing connection column is screwed out downwards, so that the pushing structure of the auxiliary spring screwing connection column pushes the stopping structure of the main spring seat to move downwards, the main spring seat drives the main spring to stretch downwards, and then the initial force value of the main spring is adjusted.
Description
technical field [0001] The invention relates to a female spring assembly and a spring seat thereof. Background technique [0002] The master spring is a kind of spring in which the mother spring and the child spring of different diameters are set together to achieve the elastic effect. Compared with a single spring, the master spring has greater resilience and a higher safety factor under the same diameter, such as in a mattress The use of double springs can effectively improve the resilience and support of the mattress, avoiding the collapse of ordinary spring mattresses. In addition, the use of double springs in the stop valve can improve the cut-off speed and reliability of the stop valve. [0003] Chinese patent (CN200965844Y) discloses a high-voltage circuit breaker spring operating mechanism. In the spring operating structure, the motor drives two-stage gear transmission, and then the transmission claw on the large gear drives the camshaft to rotate, and the camshaft d...
