Abstract
The utility model discloses an insulated pull rod for a circuit breaker. The insulated pull rod comprises an insulated body, wherein the lower end of the insulated body is connected with an adjusting head, and the upper end of the insulated body is provided with an installation groove; an adjusting spacer and a disc spring which is pressed onto the adjusting spacer are arranged in the installation groove; a connecting rod is inserted into the disc spring and is connected with the upper end of the insulated body; a spring cup insert is arranged in the installation groove, is pressed below the adjusting spacer and is provided with a projecting tongue-shaped head; the lower end of the connecting rod is provided with a U-shaped groove; and the tongue-shaped head is clamped into the U-shaped groove. Torque can be transmitted between the insulated body and the connecting rod, so that repeated disassembly and assembly are not needed in debugging and assembly processes, and no special tool is needed.
Description
(1) technical field
The utility model relates to a kind of circuit breaker insulated tension pole.
(2) background technology
At present, insulating pull rod for breaker can satisfy required mechanical property of circuit breaker and electric property as a key components and parts of circuit breaker.But, it is big and need the deficiency of aspects such as special assembling tool to remain, labour intensity not high at efficiency of assembling: in the mechanical characterisitic parameter process of debugging, often need repeatedly will be heavier pole (comprise insulation cartridge type and envelope type) admittedly disassemble from circuit breaker frame, again insulated tension pole is taken apart from pole, behind the increase and decrease adjusting pad, restore assembling; Particularly, be subjected to the restriction of solid envelope type pole inner space, insulating pull rod for breaker also must have specific purpose tool to mount and dismount, and production efficiency is very low.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of existing circuit breaker with insulated tension pole, the utility model provides a kind of efficiency of assembling height, labour intensity is little, portion need special assembling tool circuit breaker insulated tension pole.
The technical scheme in the invention for solving the technical problem is: a kind of circuit breaker insulated tension pole, comprise insulating body, the lower end of described insulating body is connected with the adjusting head, the upper end of described insulating body is provided with mounting groove, be provided with in the described mounting groove and adjust pad and the dish spring that is pressed on the described adjustment pad, be equipped with connecting rod in the described dish spring, described connecting rod is connected with the upper end of described insulating body, also has a spring cup inserts in the described mounting groove, described spring cup inserts is pressed in the below of described adjustment pad, described spring cup inserts has the ligulate head that raises up, the lower end of described connecting rod is provided with U-lag, and described ligulate head snaps in the described U-lag.
Further, the lateral surface of the bottom of described insulating body is hexagon.
Further, the bottom of described insulating body is provided with embedded nut, is with locking nut and packing ring on the described adjusting head, described adjusting head screw in behind the described embedded nut described locking nut with washer locking between described locking nut and insulating body.
Further, the upper end of described insulating body is provided with upper groove, the side of described upper groove is provided with internal thread, has convex shoulder on the described connecting rod, this connecting rod is with outward has externally threaded upper locking nut, thereby be pressed on after described upper locking nut is tightened in the described upper groove on the convex shoulder of described connecting rod described connecting rod is fixed.
Further, the described lower surface of regulating head is provided with a straight trough, and the bottom of this adjusting head is provided with radially pinned hole.
When assembling, when install adjust pad, dish spring after, the U-lag on the connecting rod is snapped in ligulate head on the spring cup inserts, again upper locking nut is screwed into internal thread on the insulating body upper end by forcing press.Because the U-lag on the connecting rod has snapped in the ligulate head on the spring cup inserts, just had the transfer torque ability between insulating body and the connecting rod, and the bottom of insulating body is the hexagonal structure of standard, therefore only need just can fast the connecting rod of insulated tension pole be screwed into the moved end conducting rod of vacuum interrupter with conventional spanner, realize the installation of insulated tension pole.
Regulate the straight trough that a lower surface has normal width, and the diameter of an adjusting lower end is than little with its circuit breaker master connecting lever inner distance that is connected.Only need earlier locking nut is unscrewed, pull down the connecting pin of regulating head and circuit breaker master connecting lever, the degree of depth that is screwed into of regulating head again with the yi word pattern screwdriver is put on connecting pin at last, tightens locking nut and makes the packing ring pressing, the adjusting of realization breaker over-travel.
The beneficial effects of the utility model are: owing to just have the transfer torque ability between insulating body and the connecting rod, therefore do not need repeated disassembled and assembled in the debugging assembling process, and also do not need specific purpose tool.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, a kind of circuit breaker insulated tension pole comprises insulating body 1, and the lateral surface of the bottom of described insulating body 1 is hexagon.The lower end of described insulating body 1 is connected with regulates 2: the bottom of described insulating body 1 is provided with embedded nut 3, be with locking nut 4 and packing ring 5 in the described adjusting 2, described adjusting 2 screws in the described locking nuts 4 in described embedded nut 3 backs packing ring 5 is locked between described locking nut 4 and the insulating body 1.The lower surface of described adjusting 2 is provided with a straight trough, and the bottom of this adjusting 2 is provided with radially pinned hole.
The upper end of described insulating body 1 is provided with mounting groove, be provided with in the described mounting groove and adjust pad 6 and the dish spring 7 that is pressed on the described adjustment pad 6, be equipped with connecting rod 8 in the described dish spring 7, described connecting rod 8 is connected with the upper end of described insulating body 1: the upper end of described insulating body 1 is provided with upper groove, the side of described upper groove is provided with internal thread, has convex shoulder on the described connecting rod 8, this connecting rod 8 outer being with have externally threaded upper locking nut 9, thereby are pressed on the convex shoulder of described connecting rod 8 described connecting rod 8 fixing after described upper locking nut 9 is tightened in the described upper groove.
Also has a spring cup inserts 10 in the described mounting groove, described spring cup inserts 10 is pressed in the below of described adjustment pad 6, described spring cup inserts 10 has the ligulate that raises up 11, and the lower end of described connecting rod 8 is provided with U-lag, and described ligulate 11 snaps in the described U-lag.
When assembling, when install adjust pad 6, dish spring 7 after, the U-lag on the connecting rod 8 is snapped in ligulate 11 on the spring cup inserts 10, again upper locking nut 9 is screwed into internal thread on the insulating body upper end by forcing press.Because the U-lag on the connecting rod 8 has snapped in the ligulate 11 on the spring cup inserts, just had the transfer torque ability between insulating body 1 and the connecting rod 8, and the bottom of insulating body 1 is the hexagonal structure of standard, therefore only need just can fast the connecting rod of insulated tension pole be screwed into the moved end conducting rod of vacuum interrupter with conventional spanner, realize the installation of insulated tension pole.
