Abstract
An adjustable-type brake-separation spring structure of a circuit breaker comprises a mounting plate, a guide plate, a brake-separation spring arranged on the guide plate, and a spring seat. The mounting plate is fixedly mounted on the wall of a circuit-breaker box body, and a guide through-hole whose shape is the same as that of the cross section of the guide plate is formed on the mounting plate; and the upper part of the guide plate mounted vertically is hinged with a crank arm through a pin shaft, the lower part of the guide plate pass through the guide through-hole, a spring seat is sleeved on the body of the guide plate, and the brake-separate spring is sleeved on the body of the guide plate between the lower plane of the spring seat and the upper plane of the mounting plate. The utility model is characterized in that the guide plate adopts a cylinder, outer threads are formed on the cylindrical surface at the upper part of the cylinder, inner threads are formed on the inner holeof the spring seat, and the cylindrical body and the spring seat are connected into a whole through the inner threads and the outer threads. The adjustable-type brake-separate spring structure has the advantages that no special tools need to be used for installation, and the reset force of the spring can be conveniently adjusted after the assembly.
Description
[technical field]
The utility model relates to the indoor vacuum circuit-breaker of a kind of ZN85-40.5, especially relates to the tripping spring structure of described circuit breaker.
[background technology]
Tripping spring structure on the existing indoor vacuum circuit-breaker of ZN85-40.5 comprises a mounting panel, a guide plate, and is arranged on guide plate plate tripping spring and spring base thereof on one's body.Mounting panel is fixedly mounted on the box of the circuit breaker body wall, has the corresponding to guide through hole of a shape and guide plate cross section on it.Guide plate be one vertically install, the cross section is the plate body of rectangle, its top is hinged through a bearing pin and a transmission crank arm, the bottom then extends through described guide through hole, the plate of guide plate is nested with spring base on one's body, spring base is by plate radial location piece location on one's body, and tripping spring then is nested with on one's body the guide plate plate between the plane on spring base lower plane and the mounting panel.During work, transmission crank arm is under a rotating shaft drives, guide plate can be done upper and lower lifting, under the decline state, spring base overcomes the tripping spring reset force makes angle of transmission crank arm rotation, finishes feed motion, during rising, utilize the reset force of tripping spring, make guide plate rising, pushing tow transmission crank arm drive the rotating shaft opposite spin and reset, realize separating brake.
Above-mentioned tripping spring structure is in application, and there are the following problems: 1, need specific purpose tool to install, inconvenience wastes time and energy.During installation, earlier an end of tripping spring is inserted in spring base, after with specific purpose tool the tripping spring that has a spring base being compressed to certain-length, again guide plate is penetrated tripping spring and spring base, move on the mounting panel that installs to the circuit breaker casing, guide plate and transmission crank arm are coupled together (transmission crank arm is contained on the circuit breaker casing frame with rotating shaft in advance) with bearing pin then, remove the specific purpose tool of compression spring after connecting.2, owing to promptly be in stationary state after the tripping spring once mounting, can't regulate its reset force, therefore, tripping spring is involutory, the isoparametric influence of opening velocity is bigger, can not adjust parameter and make it to reach desired quantity, and influence the service behaviour of whole circuit breaker.
[summary of the invention]
For overcoming the problems referred to above that prior art exists, the utility model aims to provide a kind of breaker adjustable tripping spring structure, when not only installing, this spring structure do not need to adopt specific purpose tool, and spring force can be adjusted in good time, therefore can make parameter such as circuit breaker on/off switch speed reach desired quantity, thereby can guarantee the service behaviour of whole circuit breaker.
For achieving the above object, the utility model has adopted following technical scheme: this breaker adjustable tripping spring structure comprises a mounting panel, a guide plate, and is arranged on guide plate plate tripping spring and spring base thereof on one's body; Mounting panel is fixedly mounted on the box of the circuit breaker body wall, has the corresponding to guide through hole of a shape and guide plate cross section on the mounting panel; Vertically the guide plate top of installing is hinged through a bearing pin and a transmission crank arm, the bottom then extends through described guide through hole, the plate of guide plate is nested with spring base on one's body, tripping spring is nested with on one's body the plate of the guide plate between the plane on spring base lower plane and the mounting panel, it is characterized in that: described guide plate is a cylinder, have external screw thread on the damaged surface on cylinder top, have internal thread on the endoporus of described spring base, cylinder and spring base are connected into integral body through described internal thread, external screw thread.
Aforesaid breaker adjustable tripping spring structure is characterized in that: described guide plate is an integral type cylinder, three parts of dividing diameter to increase successively from top to bottom.
Aforesaid breaker adjustable tripping spring structure is characterized in that: the damaged surface of the mid portion of described cylinder different-diameter three parts is provided with external screw thread.
Beneficial effect: compared with prior art, the utility model makes guide plate into cylinder, and after making guide plate and spring base connecting by screw thread, prior art is by the fixed structure that spring base is set of radial location piece relatively, advantage with two aspects: when 1, installing, tripping spring can penetrate cylinder under relaxed state, cylinder is realized hinged with transmission crank arm after stretching into the mounting panel guide through hole again, and then screw spring base compression tripping spring, therefore can omit specific purpose tool, time saving and energy saving convenience.Therefore 2, after the assembling, can utilize spring base to adjust the reset force of tripping spring at any time, can make parameter such as circuit breaker on/off switch speed reach desired quantity easily, thereby guarantee the service behaviour of whole circuit breaker.
[description of drawings]
Fig. 1 is the main TV structure schematic diagram of an embodiment of the utility model.
Among the figure: mounting panel 1, tripping spring 2, guide plate 3, spring base 4, bearing pin 5, transmission crank arm 6, rotating shaft 7, box of the circuit breaker body wall 8.
[embodiment]
Referring to Fig. 1.This figure only shows the adjustable tripping spring structure that is installed in box of the circuit breaker body wall 8 one sides, in fact, the bilateral symmetry of casing two cover adjustable tripping spring structures have been installed.The connecting lever at rotating shaft 7 middle parts and the mechanism of circuit breaker link, the external splines at rotating shaft 7 two ends be meshed with the internal spline of transmission crank arm 6 installing holes of both sides respectively.The cylinder upper end of transmission crank arm 6 one ends and guide plate 3 is hinged through bearing pin 5.Three parts that cylinder divides diameter to increase successively from top to bottom are provided with external screw thread on the damaged surface of cylinder mid portion, and the endoporus internal thread of this external screw thread and spring base 4 is complementary, and promptly guide plate 3 is revolved by internal and external threads with spring base 4 and unifies.The length of described cylinder mid portion can be set as required, is adjusted into principle to satisfy.During concrete the making, the external diameter of guide plate cylinder bottom is φ 30, and interlude external screw thread M24, epimere are φ 20; The spring base 4 endoporus φ 21 that match, internal thread is M24.
