[0029] like Figure 1 The four-in-one terminal shown includes the aforementioned switching structure, which can switch the opening and closing state of the terminal. The terminal includes an arc-extinguishing structure and an electromagnetic tripping structure installed inside the cavity. After the switching structure is set, the terminal state can be switched.
[0030] like Figures 2-4 The adapter structure shown includes a handle 1 and a jumper base 5 that are spaced apart and rotatably arranged relative to the same reference housing 8. The handle 1 can be manually driven to rotate, and the handle 1 and the rotation axis 51 of the jumper base 5 are arranged in the same direction to ensure that their rotation planes are parallel to each other. Therefore, when the handle 1 is manually turned, it can drive the jumper base 5 to rotate synchronously.
[0031] It should be noted that the jump buckle base 5 is provided with a first reference shaft 52 and a second reference shaft 53 at a distance from the rotation axis 51. That is, the first reference shaft 52 and the second reference shaft 53 can both rotate around the rotation axis of the jump buckle base 5, and their rotation paths are different. The first reference shaft 52 is located close to the handle 1 and is rotatably connected to the jump buckle 4, while the second reference shaft 53 is located away from the handle 1 and is rotatably connected to the lock buckle 6. Since the rotation axes of the jump buckle 4 and the lock buckle 6 are not the same, their rotation paths are also different. That is to say, the relative position and relative state of the jump buckle 4 and the lock buckle 6 will change. Therefore, locking or relative separation can be achieved through the above changes.
[0032] Furthermore, in the above structure, the locking method of the jump buckle 4 and the locking buckle 6 is that the jump buckle 4 and the locking buckle 6 are respectively provided with a limiting notch 42 and a locking notch 61 for cooperation at their adjacent ends. After the two are rotated to a certain angle, they can be locked by the mutual contact of the limiting notch 42 and the locking notch 61. Only one of them needs to be moved to release it from the locked state again. It should be noted that the jump buckle is driven by the handle 1 to change its state, while the locking buckle 6 is driven by an electromagnetic release device, the structure of which is not shown.
[0033] Furthermore, the specific design of the jump buckle 4 is such that the jump buckle 4 is connected to the handle 1 via a connecting rod 3 and moves synchronously; and as follows... Figure 2 As shown, the linkage 3 is connected in such a way that the jump buckle 4 and the handle 1 are respectively provided with a first synchronous insertion hole 11 and a second synchronous insertion hole 41 along the rotation axis 51 of the handle 1, and both ends of the linkage 3 are inserted into the synchronous insertion holes. This method facilitates the assembly and disassembly of the linkage 3, and this method can be used to change the length and other specifications of the linkage 3 according to actual usage requirements.
[0034] Furthermore, in the above structure, in order to enable the connecting rod 3 to have a certain deformation capacity, the connecting rod 3 is V-shaped. Under special circumstances, the connecting rod 3 can deform to avoid structural damage. That is to say, during the manual rotation of the handle 1, if the subsequent linkage mechanism cannot rotate, the connecting rod 3 can be stretched without causing damage to the subsequent linkage mechanism due to forced pulling.
[0035] And, in the structure, in order to ensure the reset of the handle 1, the reset torsion spring 7 is further arranged between the handle 1 and the reference shell 8, and the handle 1 is rotated relative to the reference shell 8 to the limit state of the reset torsion spring 7 being pressed, the shackle 4 can be locked relative to the lock catch 6, the locked state can be maintained, and once the locked state is released, the quick reset can be ensured. Through the above structure, the reset is realized by the reset torsion spring, which can occupy less space as much as possible, and the rotation switching state of the above structure is synchronized by the connecting rod 3, which can improve the safety, and the unique design of the connecting rod 3 can buffer through the stretching of the connecting rod 3 when the structure cannot be rotated due to problems, thereby ensuring the integrity of the structure and preventing damage to part of the structure caused by manually rotating the handle 1.
[0036] After that, when the handle 1 is reset by the reset torsion spring 7, the handle 1 is buffered in the following way: a buffer 2 is further arranged between the handle 1 and the reference shell 8, and the buffer 2 and the reset torsion spring 7 are arranged on opposite sides of the handle 1. The buffer 2 is arranged on the rotation path of the handle 1 driven by the reset torsion spring 7. During the reset process, the rigidity collision of the structural parts can be avoided by the arrangement of the buffer 2.
[0037] And, as shown in Figure 4 , 5 , the specific structure of the handle 1 is designed as follows: the handle 1 is cylindrical, and both ends are rotationally connected with the reference shell 8 through an extension cylinder 12. The extension cylinder 12 is provided with a notch limiting ring 13 and a notch buffer ring 14 on the outer side. The notch of the notch limiting ring 13 abuts against one end of the reset torsion spring 7. The buffer 2 is arranged to be sleeved on the extension cylinder 12 through a mounting circular hole 21, and a buffer arm 22 is arranged at the notch of the notch buffer ring 14. There is a gap between the buffer arm 22 and the main body of the buffer 2, and the buffer arm 22 can be bent under pressure. In this way, the handle 1 can be rotated around the extension cylinder 12, and the rotation is limited. As shown in Figure 5 , when the rotation is limited by the torsion spring 7, the handle 1 can be stressed in cooperation with the notch limiting ring 13. And the structure of the buffer arm 22 is designed as follows: the buffer arm 22 is arranged in a V shape and can be deformed to a certain extent, thereby realizing the buffering effect.
[0038] Finally, in order to facilitate the use of the handle 1, the handle 1 is provided with an extension tab extending outward relative to the reference shell 8, and the extension tab is provided with anti-slip patterns. And in the installation process, in order to avoid collision between structures, the rotation path of the handle 1 and the shackle base 5 does not coincide.
