Detailed Description

The present application is described in further detail below in conjunction with the attached figures 1-4.

The embodiment of the application discloses a spring energy storage assembly for a manual spring operating mechanism. Referring to fig. 1, a spring energy storage assembly for a manual spring operated mechanism includes a spring seat, a main spring 3 and an auxiliary spring 4. The spring seat comprises an end seat 1 and an adjusting seat 2. The main spring 3 is split into two coaxially arranged spring units 31. The two spring units 31 are connected by the adjusting seat 2. The spring unit 31 is connected to the end socket 1 at a section facing away from the other spring unit 31. When the device works, the operating mechanism changes the distance between the two spring seats through external force to compress or stretch the main spring 3 so as to finish energy storage.

Specifically, referring to fig. 2, a connection board 5 is provided on the end seat 1, the connection board 5 and the main spring 3 are coaxially arranged, a plurality of connection holes 51 are provided on both sides of the connection board 5, and the spring unit 31 passes through all the connection holes 51. So that one end of the spring unit 31 is fixedly coupled to the terminal block 1.

Referring to fig. 2 and 3, the adjusting seat 2 includes a fixing seat 21 and a rotating seat 22, and the fixing seat 21 is provided with two fixing seats and is positioned at two ends of the rotating seat 22. The rotary seat 22 is in a positive threaded connection with one fixed seat 21 and in a negative threaded connection with one fixed seat 21. The end of the fixed seat 21 facing away from the rotating seat 22 is provided with a groove 211. One end of the spring unit 31 is embedded in the groove 211 and abuts against the side wall of the groove 211, so that the spring unit 31 is fixedly connected to the adjusting seat 2.

After the spring energy storage component is mounted on the operating mechanism, whether the spring energy storage component is matched with the operating mechanism or not can be tried, and when the energy storage of the spring energy storage component is released, whether the switching-on or switching-off action required to be completed by the operating mechanism can be completed or not. If the energy storage of the spring energy storage component is released, the energy storage is insufficient to overcome the resistance, so that the switching-on or switching-off action required to be completed by the operating mechanism is completed. The distance between the two fixing bases 21 can be adjusted by screwing the rotating base 22 to adjust the elastic potential energy accumulated by the spring unit 31 in the initial state. Therefore, under the condition that the operation mechanism is not changed to store energy on the main spring 3, the main spring 3 stores more elastic potential energy under the condition of being stretched or compressed by the same length, and the main spring is ensured to have enough elastic potential energy to provide power for the subsequent closing and opening.

Referring to fig. 3, in order to allow the spring unit 31 to deform along a predetermined track when storing energy, the connection plate 5 is fixedly provided with a guide shaft 6 along its central axis, and the guide shaft 6 is disposed coaxially with the spring unit 31 and is introduced into the spring unit 31.

The two guide shafts 6 have different radiuses, and one guide shaft 6 is provided with a guide groove 61 with the same radius as the other guide shaft 6. The guide shaft 6 can limit and guide the spring unit 31, so that the spring unit 31 can move along the axial direction of the spring unit during deformation and cannot bend. When the spring unit 31 releases energy, the energy can be used in a given direction, so that the operating mechanism can be switched on or off in potential energy.

Referring to fig. 4, in another embodiment, the two guide shafts 6 have the same radius, and the guide grooves 61 are not formed. In order to ensure that the spring energy storage component has enough energy to finish closing or opening after energy storage, an auxiliary spring 4 is arranged in the main spring 3, the auxiliary spring 4 passes through the adjusting seat 2, and two ends of the auxiliary spring 4 are respectively sleeved outside the two guide shafts 6. The auxiliary spring 4 can increase the energy stored by the whole spring energy storage assembly during energy storage, so that the force provided by the spring energy storage assembly to other assemblies in the operating mechanism is enough to overcome the resistance, and the closing or opening action required to be completed by the operating mechanism is completed. Meanwhile, the auxiliary spring 4 can also have a certain limiting effect on the main spring 3, so that the spring unit 31 moves along the axial direction of the main spring during deformation and cannot bend.
