Specific implementation mode
The utility model embodiment is described further below in conjunction with the accompanying drawings：
As shown, a kind of travel switch, including upper cover 1, shell 2, control device and it is fixedly mounted on the shell 2
It is interior and by the control device control switch switch fuse 3, the control device include through the shell 2 shaft 4 with
And it is installed in the swing rod 41 of 4 one end of the shaft, it is arranged with several on the axial direction of the shaft 4, shaft 4 is followed to rotate
And the driving lever set 5 contact with the switch fuse 3 and the resetting-mechanism 6 for position state in the recovery of shaft 4, by the left or
Swing rod is swung to the right, makes shaft that driving lever set be driven to rotate clockwise or counterclockwise, and the upper convex block of driving lever set drives switch core again
The switch of son, the rotary sleeve two in resetting-mechanism limit the amplitude of fluctuation of swing rod and when not operating the moment keep in position shape
State has simple in structure, the high advantage of job stability.
The resetting-mechanism 6 includes rotary sleeve 1, torsional spring 63 and the rotary sleeve 2 62 being sleeved on successively in the shaft 4
And it is fixedly mounted on the banking stop 64 of 2 inner bottom surface of the shell, the shaft 4 drives the rotary sleeve 1 and rotary sleeve two
62 rotate movement, and it is suitable that there is when shaft 4 rotates clockwise the torsional spring 63 torsional spring 63 to occur under the drive of rotary sleeve 1
The first state of hour hands torsion and the generation torsion counterclockwise in the case where rotary sleeve 2 62 drives of torsional spring 63 when shaft 4 rotates counterclockwise
The second state turned, the excircle of the rotary sleeve 1 are equipped with the plectrum 1 with 63 one end fits of the torsional spring, are rotated
The excircle for covering 2 62 is equipped with the plectrum 2 621 coordinated with 63 other end of the torsional spring, the plectrum 1 and plectrum 2 621
It is oppositely arranged, for torsional spring when not by the initial position of torsion, the swing rod in shaft is in middle position state, and pendulum is swung toward a direction
When bar, one end reaches fixed state with banking stop conflict, and the other end makes torsional spring twist by plectrum drive, this knot
Structure have it is simple in structure, it is compact, the advantages of the operation is stable.
The rotary sleeve 2 62 is equipped with the catch 622 that can be contacted with the banking stop 64 in the both sides of the plectrum 2 621,
The banking stop 64 is domed and its height to arch upward can avoid the movement locus of the plectrum 1 and plectrum 2 621, institute
It states catch 622 and is more than the plectrum 2 621 with a distance from the center of circle with a distance from the center of circle, rotary sleeve two turns clockwise or counter-clockwise
After dynamic certain angle, catch can all touch the curved surface of banking stop side, ensure the rotational angle of shaft, make driving lever set and switch core
The work of son is more stablized.
The interlude of the shaft 4 is in polygonal prism shape, the driving lever set 5, rotary sleeve 1 and rotary sleeve 2 62 and institute
It states the adaptation of shaft 4 and can be driven by the shaft 4 and rotated, the interlude for the shaft that the present embodiment uses is in quadrangle prism,
The inner ring of driving lever set is starlike in eight awns, and shaft can drive the driving lever set 5, rotary sleeve 1 and rotary sleeve 2 62 to rotate simultaneously,
Rotating effect is good.
The shaft 4 is equipped with the detent mechanism 7 for fixing 6 position of the resetting-mechanism, and the detent mechanism 7 uses
Clamp spring 71 and the mode of the cooperation of jump-ring slot 72 and the both ends for being held and mounted on the resetting-mechanism 6, clamp spring clamp resetting-mechanism,
Do not bring it about axial displacement, it is ensured that the stability of work.
The convex block that the outer circumference surface of the driving lever set 5 is equipped with several irregular settings and coordinates with the switch fuse 3
51, the convex block controls the switch of switch core in rotation.
