Description
Technical field
The utility model relates to a kind of low pressure automatic change-over stroke adjusting device, belongs to low-voltage electrical apparatus manufacturing technology field.
Background technology
At present, CB level automatic change-over is normally made up of body (two breaker of plastic casing add a set of mechanical interlocking device) and controller two part, its structure as shown in Figure 1, formed primarily of rotating shaft 1, motor 2, connecting rod 3, pillar 4, roller 5, breaker of plastic casing 6 and pin 7.In rotating shaft 1, be provided with pin, on connecting rod 3, be provided with elongated slot 3a, roller 5 slides on pin 7, and pin 7 is arranged on connecting rod 3, and blocks with back-up ring.During work, rotating shaft 1 is driven by motor 2 carries out forward or reverse motion, and the pin in rotating shaft drives left side or right side connecting rod 3 to rotate around pillar 4 by the elongated slot 3a on connecting rod 3, and the roller 5 on connecting rod drives breaker of plastic casing 6 handle to close a floodgate or separating brake.Although this change over switch mechanical interlocking device structure is simple, but due to the error that breaker of plastic casing 6 manufactures and fit on exists, the start-stop position of every platform circuit breaker handle is also different, and the angle that its handle turns over (breaker trip) also has difference, the angle that in interlock, left linkages 3 turns over can be often made to occur not mating with the handle travel of breaker of plastic casing 6, when causing automatic change-over to switch, arranged on left and right sides breaker of plastic casing can produce and closes a floodgate or detain phenomenon not in place again, leads to great electrical equipment accident thus.
Summary of the invention
In view of above-mentioned Problems existing, the purpose of this utility model be to provide a kind of structure simple, make easily, regulate automatic change-over stroke adjusting device that is easy, dependable performance.
For achieving the above object, the utility model takes out following technical scheme:
A kind of automatic change-over stroke adjusting device described in the utility model, improvements over the prior art, it includes: rotating shaft 1, motor 2, connecting rod 3b, connecting rod 3c, pillar 4, roller 5, breaker of plastic casing 6, it is characterized in that: connecting rod 3b and connecting rod 3c is connected by screw, on connecting rod 3c, be provided with elongated slot; On connecting rod 3b, be provided with screw, both relative positions can be regulated, to adapt to the different requirement in moulded case circuit breaker handle start-stop position; On described connecting rod 3c, be provided with screw rod 10, screw rod 10 and connecting rod 3c, for being threaded, on screw rod 10, are set with locking plate 8, and fastening with nut 9, spring washer, to prevent the rotation of screw rod 10.
Automatic change-over stroke adjusting device after above-mentioned design, by the relative position of regulating connecting rod 3b, connecting rod 3c, makes the outgoing position of left and right connecting rod adapt to the requirement of the handle start-stop position of corresponding breaker of plastic casing well; By the axial location of the relative connecting rod 3c screw of adjusting screw(rod) 10, change the roller 5 on screw rod 10 and the contact position of circuit breaker handle, effectively can adapt to the requirement of circuit breaker handle corner.

Embodiment
Below in conjunction with accompanying drawing, specific embodiments of the present utility model is described in detail:
With reference to accompanying drawing, a kind of automatic change-over stroke adjusting device described in the utility model, be improvements over the prior art, it includes: rotating shaft 1, motor, connecting rod 3b, 3c, pillar 4, roller 5, breaker of plastic casing 6; Connecting rod of the prior art is split as two parts by the utility model, and namely connecting rod 3b and connecting rod 3c, connecting rod 3b and connecting rod 3c are connected by screw.Connecting rod 3c is provided with elongated slot; Connecting rod 3b is provided with screw, both relative positions can be regulated, to adapt to the different requirement in moulded case circuit breaker handle start-stop position.
The utility model has made pin 7 of the prior art into screw rod 10, former pin 7 is shaft hole matching with connecting rod 3, now make screw rod 10 into connecting rod 3c for being threaded, with the upper and lower position regulating roller 5 to act on circuit breaker handle, adapt to the requirement of circuit breaker handle stroke, after adjustment, load onto locking plate 8, and fastening with nut 9, spring washer, locking plate 8 flange is locking, prevents the rotation of screw rod 10.
The automatic change-over stroke adjusting device of the utility model design, by the relative position of regulating connecting rod 3b, 3c, makes the outgoing position of left and right connecting rod adapt to the requirement of the handle start-stop position of corresponding breaker of plastic casing well; By the axial location of the relative connecting rod 3c screw of adjusting screw(rod) 10, the roller 5 on change screw rod 10 and the contact position of circuit breaker handle, to adapt to the requirement of circuit breaker handle corner.
The utility model structure is simple, making is easy, regulate easy, dependable performance, the dark favorable comment being subject to switch assembling and commissioning staff.
