Detailed Description
In order to make the aforementioned and other features and advantages of the utility model more comprehensible, embodiments accompanied with figures are described in detail below.
As shown in fig. 1-7, an interlocking mechanism applied to air switches comprises an interlocking frame 2 located between two air switches 1, wherein a slot 3 is transversely penetrated through the middle of the interlocking frame, the slot longitudinally penetrates out of the interlocking frame towards the back, the interlocking frame is tightly attached to the surface of a plate cabinet except the slot position and locked by a bolt 13, a left locking plate 4 and a right locking plate 5 which are close to each other are arranged in the slot in an inserting mode, the two locking plates can transversely slide in the slot and are fastened by a locking bolt 6 which is longitudinally screwed in, a strip-shaped through hole 7 is formed in each of the left locking plate and the right locking plate for the locking bolt to pass through, a left clamping block 8 is fixedly connected to one end, close to the left air switch, of the left locking plate, and a right clamping block 9 is fixedly connected to one end, close to the right air switch, of the right locking plate.
In the embodiment of the utility model, the front end face of the left locking plate is provided with the transversely extending chute 10, the right locking plate is arranged at the front end of the left locking plate and slides in a matching way with the left locking plate through the protruded sliding block 11, the sliding block is fixedly arranged on the rear end face of the right locking plate, the design of the sliding block and the sliding rail effectively ensures that the two locking plates always horizontally move when transversely sliding, the problem of dislocation is avoided, and meanwhile, the size of the slot is matched with the two locking plates, so that the two locking plates are ensured not to generate angle deflection, namely, the left and right clamping blocks are always in a vertical state.
In the embodiment of the utility model, the sizes of the through holes on the left locking plate and the right locking plate are consistent, the surface of the interlocking frame positioned at the front end of the slot is provided with the abdicating hole 12 which transversely extends from left to right, the locking bolt passes through the abdicating hole, and the abdicating hole is designed to avoid the problems that the sizes of the through holes are insufficient and the clamping block cannot be locked in place.
In the present embodiment, both air switches and the interlock bracket are fixedly mounted to the cabinet 14.
In the embodiment of the utility model, the left clamping block and the right clamping block extend vertically, the front and back thicknesses of the left clamping block and the right clamping block are consistent with the thicknesses of the left locking plate and the right locking plate after being tightly attached, the left clamping block and the left locking plate are fixedly integrated, and the right clamping block and the right locking plate are fixedly integrated.
The working principle of the embodiment of the utility model is as follows:
(1) if a simultaneous closing test is required, the left locking piece and the right locking piece are kept in a front-back superposition state, the left clamping block and the right clamping block are both far away from the two air switches, and the locking bolt is screwed and fixed (as shown in fig. 1).
(2) If the air switch normally operates, namely the air switch cannot be switched on or switched off simultaneously, based on the state of (1), the locking bolt is unscrewed, then the locking plate at one end moves towards the air switch, the air switch disconnected at the side is subjected to limiting locking through the clamping block at the side, the air switch at the other side is in a switched-on state, the locking bolt is screwed (as shown in figure 3), the clamping block at the side is withdrawn during switching, the air switch at the other side is disconnected, the locking plate at the side is moved outwards to be locked, and finally the air switch disconnected originally is switched on.
(3) If the air switches need to be disconnected simultaneously, based on the state in the step (1), the locking bolt is unscrewed, the left locking plate moves transversely towards the left, the right locking plate moves transversely towards the right, the two air switches are disconnected and are respectively locked in a limiting mode through the left clamping block and the right clamping block, and finally the locking bolt is screwed (as shown in the figure 4).
The present invention is not limited to the above-described preferred embodiments, and various other types of interlock mechanisms for air switches can be devised by anyone who can use the present invention. All equivalent changes and modifications made according to the claims of the present invention should be covered by the present invention.
