detailed description

In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples and accompanying drawings. As a limitation of the present invention.

Example:

As shown in Figure 1, an automatic air control system used in the electric power field includes a hollow casing 1, in which a pneumatic mechanism, a bracket 13 and a mounting seat 17 are arranged, and the mounting seat 17 and the casing 1 The inner wall is fixed, and the mounting seat 17 is arranged between the bracket 13 and the pneumatic mechanism. , the pressure head 11 is connected with a contact plate 9, and the contact plate 9 protrudes from the support 13 away from the end of the pneumatic mechanism. It is arranged outside the bracket 13, and the fixed axis fulcrum 10 is arranged inside the bracket 13. The bracket 13 is provided with an arc-shaped through groove 5, and the arc-shaped through groove 5 is provided with a pin shaft 6, and the pin shaft 6 passes through the contact plate 9, and The contact plate 9 can rotate around the pin shaft 6, and the pin shaft 6 can move along the arc surface of the arc-shaped slot 5 in the arc-shaped slot 5, and a spring 4 is arranged between the pressure head 11 and the bracket 13, and the spring 4. One end is fixed to the support 13, and the other end is connected to the spring support piece 12, and the spring support piece 12 is connected to the indenter 11. A telescopic rod 14 is arranged between the indenter 11 and the support 13. Between the telescopic rod 14 and the indenter 11 A hinge is provided between the telescopic rod 14 and the bracket 13, and the hinge is connected with the corresponding telescopic rod 14, the pressure head 11 or the bracket 13, the telescopic rod 14 is arranged above the spring 4, and the housing 1 is provided with a contact Two 7, the contact two 7 is arranged under the contact one 8, and the contact one 8 can be in contact with the contact two 7 when the contact plate 9 rotates around the pin shaft 6; the pneumatic mechanism includes a cylinder 18 connected to each other And air pump 3, and cylinder 18 is connected with link mechanism 15, is provided with protective cover 16 between cylinder 18 and support 13, and protective cover 16 is connected with cylinder 18 and support 13 simultaneously; A current sensor 2, and the current sensor 2 is connected with the air pump 3. When the bakelite handle of the switch is closed, the current sensor 2 detects that the current passes through, and sends a signal to the air pump 3, so that the air pump 3 is started, and the cylinder 18 is inflated to drive the connecting rod mechanism 15 to move, and the contact plate 9 is pushed to move, and the contact one 8 is The moving contact, contact two 7 is a static contact, so that contact one 8 has a tendency to close with contact two 7. During this movement, the spring 4 in the bracket 13 is compressed; at the same time, due to the angle change, the spring Support piece 12 and pressure head 11 and fixed axis fulcrum 10, when three points exceed the dead angle (180 °) in line, spring 4 elongates, gives pressure head 11 certain thrust, pin shaft 6 moves in arc-shaped through groove 5, and The contact plate 9 rotates around the pin shaft 6, so that the first contact 8 and the second contact 7 are closed. When the current sensor 2 detects that the signal exceeds the set current value, the air pump 3 retracts the cylinder and pulls the pressure head 11 back to its position, so that the first contact 8 and the second contact 7 are out of contact, and the power is cut off to ensure safe use. The protective cover 16 is used to seal the parts exposed outside when the end of the cylinder pulls the link mechanism 15 to move, so as to prevent dust or rust residue from hindering the movement of the inner parts of the cylinder. The telescopic rod 14 is used to pull the pressure head 11. When the contact plate 9 rotates under the gravity, and the contact one 8 and the contact two 7 are closed, the telescopic rod 14 is extended to a certain extent to slow down the contact plate. 9, the impact force when rotating ensures that the closing process of contact one 8 and contact two 7 is stable, reduces the impact force inside the equipment, makes the service life of the equipment longer, and the telescopic rod 14 can rotate around the hinge so that it can adapt to the pressure. When the angle changes when the head moves, the action of the whole system can be carried out in an orderly manner to prevent interference and jamming. The pneumatic method is used as the power mechanism to ensure that its action is fast and not jammed, which improves its safety and solves the problem of existing air switches. When the opening and closing process is controlled, its action mechanism is prone to jamming, resulting in failure of opening and closing, and there is a problem of potential safety hazard.
