Specifically, in one possible mode of the present utility model, the limiting structure includes a baffle plate 102 of the operating mechanism disposed in the upper cover 10, the connecting plate 100 is linked with the baffle plate 102 through a connecting rod 101, and when the connecting plate 100 abuts against the baffle plate 102, a gap t is formed between the connecting plate 100 and the inner wall of the upper cover 10.
When the connecting plate 100 rotates, the connecting rod 101 is driven to act, and the connecting rod 101 pushes the baffle plates 102 to compress a pressure spring (not shown in the figure) between the two baffle plates 102 so as to realize closing; as shown in fig. 1, the connection plate 100 has a state of abutting against the baffle plate 102, when the connection plate 100 rotates clockwise to a position of abutting against the baffle plate 102, the baffle plate 102 blocks the trend of the connection plate 100 to continue rotating, so that the connection plate 100 cannot get close to the boss 10b of the upper cover 10 any more, a gap t is formed between the connection plate 100 and the boss 10b of the upper cover 10, and at this time, the disconnecting switch is disconnected; the handle drives the connecting plate 100 to reversely rotate, the connecting plate 100 rotates anticlockwise to release the abutting state with the baffle plate 102, and the connecting plate 100 moves in a direction away from the boss 10b of the upper cover 10, so that closing is realized.
For example, as shown in fig. 4, two symmetrical protrusions 100a are disposed at the end of the connection board 100, the baffle 102 is provided with a flange 102a, and when the two protrusions 100a respectively abut against the flange 102a, the connection board 100 is limited in the opening and closing states respectively. Fig. 1 shows that in the opening state, the lower protrusion 100a of the connecting plate 100 and one flange 102a of the baffle 102 abut against and limit, and at this time, a gap t is formed between the connecting plate 100 and the boss 10b of the upper cover 10 due to the limiting effect of the baffle 102 on the connecting plate 100; when the connecting plate 100 is reversely rotated, closing can be realized, when the connecting plate 100 rotates to the position where the upper side bulge 100a and the flanging 102a of the connecting plate 100 are propped against each other, the connecting plate 100 can be limited in a closing state, at the moment, the gap t between the right upper end of the connecting plate 100 and the boss 10b is increased, the left upper end of the connecting plate 100 and the inner wall of the corresponding position of the upper cover 10 are not touched, and the impact of the connecting plate 100 on the upper cover 10 is avoided; the two protrusions 100a of the connecting plate 100 respectively realize the functions of opening and closing limiting, in the opening state, the impact force of the connecting plate 100 on the boss 10b is larger, and in the closing state, the impact of the connecting plate 100 on the inner wall of the upper cover 10 is buffered.
The two sides of the baffle plate 102 are respectively provided with symmetrical flanges 102a, wherein the flange 102a at one side is abutted against the protrusion 100 a. As shown in fig. 5, two flanges 102a are respectively formed on two sides of the baffle 102, four flanges 102a are formed on the baffle 102 in a conformal manner, and the four flanges 102a are symmetrical in a left-right mode and a top-bottom mode; wherein the flange 102a on the lower right side is used for propping and limiting with the protrusion 100a of the connecting plate 100; when the flanges 102a on the baffle plate 102 are symmetrically arranged, the baffle plate 102 can be arbitrarily installed, and the assembly foolproof is ensured.
In another possible implementation of the present utility model, as shown in fig. 6, the limiting structure includes an elastic buffer member 103 disposed in the upper cover 10, and when the connecting plate 100 abuts against the elastic buffer member 103, a gap t is formed between the connecting plate 100 and an inner wall of the upper cover 10.
The elastic buffer 103 may be a rubber member or other elastic member, where the elastic buffer 103 is disposed near the connecting plate 100, and when the connecting plate 100 rotates, the rotation of the connecting plate 100 is limited by the abutting action of the connecting plate 100 and the elastic buffer 103.
Specifically, two symmetrical extension rods 100b extend from the connection plate 100, and the two extension rods 100b respectively abut against two side walls 103a of the elastic buffer member 103, so as to limit the connection plate 100 in the opening and closing states respectively.
Two symmetrical extension rods 100b are arranged on the connecting plate 100, and fig. 6 shows a limiting state of one side wall 103a of the elastic buffer member 103 to one extension rod 100b of the connecting plate 100 in a brake-separating state, wherein a gap t is formed between the connecting plate 100 and the boss 10b of the upper cover 10; when the connection plate 100 rotates reversely, the other side wall 103a of the elastic buffer 103 limits the other extension rod 100b of the connection plate 100, so as to realize the limitation in the opening state.
As shown in fig. 7, a boss is provided on a side of the elastic buffer 103 facing the connection plate 100, an end of the connection plate 100 is overlapped on a table 103b of the boss, and two side walls 103a are respectively located on two sides of the table 103 b.
The elastic buffer member 103 forms a structure with an L-shaped side wall 103a, a boss is formed at the position of the elastic buffer member 103 facing the connecting plate 100, when the connecting plate 100 rotates, the end part of the connecting plate 100 is lapped on a table top 103b of the boss, and rotates along the table top 103b, and the table top 103b gives a certain bearing capacity to the connecting plate 100; when the connection plate 100 rotates until the extension rod 100b thereof is blocked by the side wall 103a of the elastic buffer 103, the connection plate 100 cannot continue to rotate any more, and at this time, the limit of the connection plate 100 is realized.
In addition, the elastic buffer 103 is further formed with a avoiding surface 103c perpendicular to the table top 103b, the avoiding surface 103c is an arc surface, and the end of the connecting plate 100 is matched with the arc surface.
The avoidance surface 103c faces the direction of the connecting plate 100, the avoidance surface 103c is perpendicular to the table top 103b and is connected with the table top 103b, and the avoidance surface 103c is an arc surface matched with the end part of the connecting plate 100, so that when the connecting plate 100 rotates, the end part of the connecting plate 100 is lapped on the table top 103b, and the avoidance surface 103c is used for avoiding the end part of the connecting plate 100, so that the connecting plate 100 can smoothly rotate.
In summary, the rotation of the connecting plate 100 is limited by the limiting structure, so that a gap t is formed between the connecting plate 100 and the inner wall of the upper cover 10, and the influence on the reliability of the upper cover 10 caused by repeatedly knocking the inner wall of the upper cover 10 when the connecting plate 100 is switched on and off in rotation is avoided; the utility model provides two examples of a limiting structure, one is that the baffle plate 102 of the operating mechanism is used for rigidly blocking the connecting plate 100 so as to limit the connecting plate 100; still another way is to elastically block the connection board 100 by the elastic buffer member 103, and limit the connection board 100 is also realized. Of course, the utility model is not limited to the two limiting modes, and can be specifically set according to actual needs. By the limiting structure, cracks of the upper cover 10 caused by repeated knocking of the connecting plate 100 are avoided, and reliability of products is ensured.

The operating handle drives the connecting plate 100 to rotate, and the connecting plate 100 drives the operating mechanism to act, so that the switching-on and switching-off of the switch unit are realized. When the connecting plate 100 rotates, the connecting plate 100 and the inner wall of the upper cover 10 form a gap t all the time by limiting the limiting structure, so that the upper cover 10 is prevented from cracking due to repeated knocking of the upper cover 10 when the connecting plate 100 is switched on and off, and the overall reliability of the isolating switch product is ensured.
The isolating switch has the same structure and beneficial effects as the isolating switch opening and closing limiting structure in the previous embodiment.
