Detailed Description
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "provided", "sleeved/connected", "connected", and the like are to be understood in a broad sense, such as "connected", which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1-4, the present invention provides a technical solution:
a mechanical interlock for a switchgear circuit breaker, as shown in fig. 1, the mechanical interlock comprising:
the device comprises a support plate 2, a fixed frame 7, a guide rod 5, a transmission plate 3 and a transverse plate 8. Wherein:
the fixing frame 7 is fixedly arranged on the support plate, and the cushion block 6 is further arranged on the fixing frame 7. The guide rod 5 is arranged on the cushion block 6, and the horizontal two ends of the guide rod 5 are parallel and the middle part of the guide rod is of an inclined structure; the transmission plate 3 is movably arranged on the surface of the support plate 2. The transmission plate 3 is connected with the guide rod 5 to form power fit, so that when the transmission plate 3 moves vertically, the guide rod 5 moves horizontally.
It should be noted that, in this embodiment, the guide rod 5 is divided into three parts, two ends of the guide rod are horizontal structures, and the middle part of the guide rod is an inclined structure. The horizontal ends at the two ends are different in height, and the right horizontal section is higher than the left horizontal section. The inclination angle of the inclined structure (i.e. the angle between the inclined structure and the left horizontal segment or the right horizontal segment) is 120-150 degrees.
In this embodiment, the support plate 2 is provided with a fixing screw 9, and a transverse plate 8 is fixedly installed through the fixing screw 9. The transverse plate 8 plays a role in fixing the driving plate 3 to move up and down, and prevents the driving plate 3 from deviating when moving up and down.
And a first tension spring 4 is further installed on the transverse plate 8, and the end part of the first tension spring 4 is connected with the transmission plate 3.
The first tension spring 4 has the following functions: because the transmission plate 3 is pressed downwards by external force to move, when the transmission plate 3 is pressed downwards by the external force, the tension spring I4 is driven to extend and form elasticity (also called tension or acting force opposite to the external force); when the external force is no longer pressed down, the elastic force (also called pulling force or acting force in the opposite direction of the external force) formed by the first tension spring 4 drives the transmission plate 3 to move (reset) in the opposite direction of the external force.
Referring to fig. 2 and 3, the specific operation of the driving plate 3 when it is pressed down by an external force can be seen, specifically describing: the maximum range of the distance by which the driving plate 3 is pressed down by the external force is 45mm to 63mm, which is a limit range indicating the maximum distance by which the driving plate 3 moves. That is to say: when the transmission plate 3 is pressed down to 45mm to 63mm, the guide rod 5 can extend out of the support plate 2 to achieve the purpose of connecting with an external circuit breaker.
In this embodiment, a second tension spring 14 is disposed on the fixing frame 7, and an end of the second tension spring 14 is connected to the guide rod 5.
In this embodiment, the interlocking bracket 1 is fixedly mounted on the support plate 2.
Specifically, interlocking support 1 installs the outer wall all around at support plate 2, plays the effect of strengthening rib, makes the interlocking basis inconvenient, also is used for the basis installation.
In this embodiment, the second bearing 11 and the third bearing 12 are disposed on the support plate 2, and the second bearing 11 and the third bearing 12 are disposed on two sides of the transmission plate 3 respectively and are in sliding contact with the transmission plate 3.
Specifically, the second bearing 11 and the third bearing 12 are respectively arranged on two sides of the driving plate 3, and function as a rail for providing downward movement for the driving plate 3, so that the driving plate 3 is prevented from being deviated when moving downward.
In this embodiment, the bearing plate 2 is provided with a first bearing 10, and the outer wall of the first bearing 10 is in sliding contact with the transmission plate 3.
Referring to fig. 4, the driving plate 3 on the right side is pressed by external force, and the driving plate 3 drives the guide rod 5 on the right side to extend out to the outside of the support plate 2 so as to achieve the purpose of being connected with an external circuit breaker.
Specifically, the range of the pressing distance of the drive plate 3 on the right side is the same as the range of the pressing distance of the drive plate 3 on the left side, and the ranges are both 45mm to 63mm.
In this embodiment, the external force of the pressing down of the left and right transmission plates 3 is caused by two different breaker drives. When the left side driving plate 3 is pressed down to drive the left guide rod 5 to extend out, the external circuit breaker connected with the right side driving plate 3 cannot be switched on, and therefore the driving plate 3 on the right side cannot be pressed down. Only when the left driving plate 3 is not pressed down, the reset state is returned, and the right driving plate 3 can be pressed down.
And when the transmission plate 3 on the right side is pressed down to drive the guide rod 5 on the right side to extend, the external circuit breaker connected with the transmission plate 3 on the left side cannot be switched on, so that the transmission plate 3 on the left side cannot be pressed down.
Only when the right side driving plate 3 is not pressed down, the reset state is returned, and the left side driving plate 3 can be pressed down.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
