Referring to fig. 1-4, preferred embodiments of the present invention are provided.
A circuit switch interlocking device comprises a switch structure 10, a limiting piece 200 and a clamping piece. The number of the switch structures 10 is not less than two, and the switch structure 10 includes a sliding piece 100, the sliding piece 100 has a linear sliding stroke, the sliding piece 100 slides in the sliding stroke to realize the opening and closing of the switch structure 10, the sliding stroke has an opening point and a closing point corresponding to the opening and closing of the switch structure, namely, when the sliding piece 100 slides to the opening point, the switch structure 10 corresponding to the sliding piece is opened, and when the sliding piece 100 slides to the closing point, the switch structure 10 corresponding to the sliding piece is closed. The sliding strokes of the sliding members 100 are arranged in parallel, and the opening point and the closing point of each switch structure 10 are located on the same side, that is, when all the sliding members 100 slide in the same direction, the state change of all the switch structures 10 is the same. The same end of each sliding member 100 is connected to a limiting member 200, and the limiting member 200 slides along with the sliding of the sliding member 100, but of course, the limiting member 200 may be connected with the sliding member 100 in an integrated manner, and the limiting member 200 includes a limiting opening 220 and a first limiting flange 210. The locking member includes a rotating shaft 310, and a first locking head 320 and a second locking head 330 connected to the circumferential side of the rotating shaft 310, wherein the rotation of the rotating shaft 310 drives the first locking head 320 and the second locking head 330 to rotate, or the rotation of the first locking head 320 or the second locking head 330 drives the rotating shaft 310 to rotate. The first locking head 320 abuts against the first position-limiting flange 210 under certain conditions, wherein when one of the sliding members 100 slides from the opening point to the closing point, the first position-limiting flange 210 of the position-limiting member 200 connected thereto pushes the first locking head 320 to rotate around the rotating shaft 310, so that the second locking head 330 rotates along with the rotating shaft 310 to a position clamped in the position-limiting opening 220 of the position-limiting member 200 connected to the other sliding member 100, thereby limiting the other sliding member 100 from the opening point to the closing point.
The specific working process of the circuit switch interlocking device is as follows:
in an initial state, the sliding elements 100 of all the switch structures 10 are at the opening point, at this time, when one of the sliding elements 100 slides to the closing point (i.e., as shown in fig. 2, the sliding element 100 slides upward), the first limiting flange 210 on the limiting element 200 connected thereto pushes the first locking head 320 to rotate around the rotating shaft 310, at this time, the rotating shaft 310 rotates to drive the second locking head 330 to rotate along with the rotating shaft, when the sliding element 100 slides to the closing point, the second locking head 330 rotates to the limiting opening 220 on the limiting element 200 connected to the other sliding element 100, so that the other limiting element 200 is locked, and further the other sliding element 100 cannot slide, and finally the other switch structures 10 cannot be closed, so that the purpose that only one switch structure 10 can be closed is achieved. The mechanical structure is very simple, is not easy to break down, has high reliability and simple maintenance, and can skillfully meet the interlocking requirement of each switch structure 10.
In this embodiment, the first locking head 320 and the second locking head 330 are integrally formed, that is, the first locking head 320 and the second locking head 330 are integrally connected, such a structure may be that when the first locking head 320 is pushed to rotate around the rotation shaft 310, the second locking head 330 may be more stably responded to rotate around the rotation shaft 310, and the integral arrangement of the first locking head 320 and the second locking head 330 may make the overall structure of the interlock device more stable, meanwhile, after the first locking head 320 and the second locking head 330 are integrally connected, the response of the second locking head 330 to the action of the first locking head 320 does not need to depend on the rotation of the rotating shaft 310, at this time, the rotating shaft 310 can be set to be stationary, and the whole body formed by the first locking head 320 and the second locking head 330 is connected with the rotating shaft 310 to form a shaft hole, so that the whole body formed by connecting the first locking head 320 and the second locking head 330 can rotate freely around the rotating shaft 310.
In this embodiment, the interlocking device further includes an elastic resetting member, the elastic resetting member may be specifically a torsion spring or other structures, the elastic resetting member is connected to the rotating shaft 310, so as to generate a state in which the first lock head 320 of the rotating shaft 310 always abuts against the first limiting flange 210, the first limiting flange 210 is located on the limiting member 200 connected to the slider 100 that slides from the opening point to the closing point, that is, the first lock head 320 always abuts against the first limiting flange 210 on the limiting member 200 connected to the slider 100 that slides from the opening point to the closing point, and the other limiting flanges are separated from the first lock head 320.
In practical situations, the rotating shaft 310 can be arbitrarily set, and only the linkage effect of the first locking head 320 and the second locking head 330 needs to be satisfied, and the first locking head 320 and the second locking head 330 can generate a connection interaction relationship with the limiting member 200, however, in order to make the whole structure of the interlocking device more stable, in this embodiment, the rotating shaft 310 is set to be perpendicular to the sliding stroke of all the sliding members 100, and such a structure can be more convenient for the first locking head 320 and the second locking head 330 to realize the connection interaction with the limiting member 200.
It should be noted that, the first locking head 320 and the second locking head 330 can be connected and interacted with the limiting members 200 at the same time, and for the specific structure of the first locking head 320 and the second locking head 330, the cross section thereof may be a strip-shaped structure as shown in fig. 1, however, the manufacturing material of the first locking head 320 and the second locking head 330 is greatly wasted, in order to avoid this, in this embodiment, the first locking head 320 includes a plurality of first locking sub-heads, the second locking head 330 includes a plurality of second locking sub-heads, the first locking sub-heads and the second locking sub-heads are respectively arranged in pairs in one-to-one correspondence, and the paired first locking sub-heads and the paired second locking sub-heads are respectively matched with the limiting members 200 in one-to-one correspondence, that is, the paired first locking sub-heads and the paired second locking sub-heads have the same number as the limiting members 200, each paired first locking sub-head and each second locking sub-head only generate a connection, however, all the first sub-lock heads and the second sub-lock heads are linked simultaneously, so that the structure can not only realize the functions of the first lock head 320 and the second lock head 330, but also greatly save the manufacturing materials.
In this embodiment, the circuit switch interlock device includes three switch structures 10, and three switch structures 10 are combined to form a three-phase circuit breaker, and because the requirement that only one switch structure 10 is required to be closed and other switch structures 10 can not be closed often appears in the three-phase circuit breaker, the device can be better realized. Of course, the device can be used in other circuits.
In this embodiment, the retaining member 200 further comprises a second retaining flange 230, the second retaining flange 230 is configured to abut against the second locking head 330 when the slider 100 connected to its corresponding retaining member 200 slides to the closing point, that is, after a sliding member 100 slides from the opening point to the closing point, the second position-limiting flange 230 thereon abuts against the second locking head 330, and the second locking head 330 is locked in the position-limiting openings 220 of the other position-limiting members 200, for the limiting member 200 sliding along the sliding member 100, the first limiting flange 210 abuts against the first lock head 320, the second limiting flange 230 abuts against the second lock head 330, thus, the position limiting member 200 can completely position the whole body formed by the first locking head 320 and the second locking head 330, the second locking head 330 can be more stably clamped in the limiting openings 220 of the other limiting members 200, so that the interlocking effect of the whole device is enhanced.
In this embodiment, in order to reduce the processing difficulty of the limiting member 200, the limiting opening 220 is set to be a gap between the first limiting flange 210 and the second limiting flange 230, so that the limiting opening 220 does not need to be processed separately, and the first limiting flange 210 and the second limiting flange 230 only need to be set so that the limiting opening 220 can be generated by the cooperation of the two.
In this embodiment, the stopper 200 is a rotator, which is more convenient to process.
In the present embodiment, the sliding stroke is linear, and the linear sliding stroke is more favorable for the sliding of the sliding member 100.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
