Description
Technical field
The utility model relates to a kind of circuit breaker, and more particularly, it relates to the tripping mechanism in a kind of circuit breaker.
Background technology
At present, the tripping mechanism on market in circuit breaker, it comprises lever and snap close, torsion spring is arranged on the locating piece of Shell of circuit breaker projection, because, when assembling, before this torsion spring set was located on locating piece, lever and snap fit are placed in Shell of circuit breaker, then are conflicted with lever and snap close respectively in the two ends of torsion spring, again because, torsion spring is the bottom being pressed in lever and snap close, Shell of circuit breaker inside is less for the space of assembling, and therefore, assembling is comparatively inconvenient and efficiency is low; In addition, limiting lock buckles the backstay of projection operationally, is first to conflict with the edge of lever, so take certain space for backstay action need, cause, other Assembly of the parts space used is less, is that assembling increases difficulty.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide the tripping mechanism in a kind of circuit breaker easy for installation.
For achieving the above object, the utility model provides following technical scheme:
Tripping mechanism in a kind of circuit breaker, comprise lever and the snap close of flexible connection, also comprise torsion spring, the end face of described lever is convexly equipped with locating piece and block, described torsion spring set be located on locating piece and its one end and block inconsistent, on the other end and snap close, the fixture block of projection is inconsistent and caught on by the projection on fixture block; Described snap close is provided with two guide vane end stops, and two guide vane end stops are wholely set by connecting rod, and described connecting rod and snap close are wholely set.
The utility model is set to further: described lever offers location notch, and described lever is convexly equipped with inserted link on the other end of relative positioning block, and the end face of described snap close opposing levers is provided with
For insert backstay in location notch and
For being set in the sleeve pipe on inserted link.
The utility model is set to further: described inserted link is set to taper, and the direction that the external diameter of described inserted link inserts in sleeve pipe according to it reduces gradually.
The utility model is set to further: the spacing between the outer wall of described inserted link maximum radius position and the inwall of sleeve pipe is 0.01mm ~ 0. 05mm; Spacing between the outer wall of described inserted link least radius position and the inwall of sleeve pipe is 0.03mm ~ 0. 1mm.
The utility model is set to further: described backstay, sleeve pipe and fixture block are wholely set.
By adopting technique scheme, torsion spring is directly set on the locating piece of projection on lever, on one end of torsion spring and lever, the block of projection is inconsistent, fixture block on the other end and snap close is inconsistent, and is caught on by projection, and snap close catches on one end of torsion spring by projection, occur following drawback in order to prevent when taking the lever and snap close that are assembled together, when one, grappling lever, under latching in the Action of Gravity Field of self, be separated with lever; When two, grappling snap close, lever, under the Action of Gravity Field of self, is separated with snap close.Therefore, this setting and torsion spring convenient for assembly, also convenient being placed in Shell of circuit breaker together with torsion spring by lever is assembled, increase work efficiency, two guide vane end stops that snap close is provided with also are connected by connecting rod, and the spacing between two guide vane end stops is the rotary amplitude of snap close, therefore, play the effect of restriction, prevent snap close rotation amplitude excessive and affect result of use.

Embodiment
Referring to figs. 1 through Fig. 4, the tripping mechanism embodiment in the utility model circuit breaker is described further.
With reference to shown in Fig. 1, tripping mechanism in a kind of circuit breaker, comprise lever 1 and the snap close 2 of flexible connection, also comprise torsion spring 3, the end face of lever 1 is convexly equipped with locating piece 11 and block 12, torsion spring 3 is directly set on the locating piece 11 of projection on lever 1, on one end of torsion spring 3 and lever 1, the block 12 of projection is inconsistent, fixture block 21 on the other end and snap close 2 is inconsistent, and caught on by projection 211, the effect of torsion spring 3 helps snap close 2 to return to initial condition, snap close 2 catches on one end of torsion spring 3 by the projection 211 be wholely set, occur following drawback at the lever 1 be assembled together of taking with during snap close 2 in order to prevent, one, when grappling lever 1, snap close 2 is under the Action of Gravity Field of self, be separated with lever 1, when two, grappling snap close 2, lever 1, under the Action of Gravity Field of self, is separated with snap close 2.Therefore, this setting and torsion spring 3 convenient for assembly, also convenient being placed in Shell of circuit breaker together with torsion spring 3 by lever 1 is assembled, increase work efficiency, snap close 2 is provided with two guide vane end stops 4, two guide vane end stops 4 are wholely set by connecting rod 5, connecting rod 5 and snap close 2 are wholely set, two guide vane end stops 4 that snap close 2 is provided with also are connected by connecting rod 5, spacing between two guide vane end stops 4 is the rotary amplitude of snap close 2, therefore, play the effect of restriction, prevent snap close 2 rotation amplitude excessive and affect result of use.
With reference to shown in Fig. 2,3, lever 1 offers location notch 13, lever 1 is convexly equipped with inserted link 14 on the other end of relative positioning block 11, the end face of snap close 2 opposing levers 1 is provided with for inserting location notch 13 inner position bar 22 and for being set in the sleeve pipe 23 on inserted link 14, backstay 22, sleeve pipe 23 and fixture block 21 are wholely set.After assembling, backstay 22 is plugged in the location notch 13 offered in lever 1, reduces backstay 22 activity and takies space in Shell of circuit breaker.
With reference to shown in Fig. 4, inserted link 14 is set to taper, and the direction that the external diameter of inserted link 14 inserts in sleeve pipe 23 according to it reduces gradually.Spacing between the outer wall of inserted link 14 maximum radius position and the inwall of sleeve pipe 23 is 0.01mm or 0.03mm or 0. 05mm; Spacing between the outer wall of inserted link 14 least radius position and the inwall of sleeve pipe 23 is 0.03mm or 0.05mm or 0.07mm or 0. 1mm.It is conveniently be inserted in sleeve pipe 23 that inserted link 14 is set to taper, above-mentioned setting, between the inwall of inserted link 14 and sleeve pipe 23, spacing is less, rock in sleeve pipe 23 to prevent inserted link 14, improve the stability that inserted link 14 coordinates with sleeve pipe 23, in addition, inserted link 14 coordinates the fulcrum rotated as snap close 2 opposing levers 1 with sleeve pipe 23.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
