Description
Technical field
The utility model relates to a kind of auto Electric Switches, particularly relates to a kind of journey variable formula brake gear; Belong to auto parts and components.
Background technology
As everyone knows, braking light switch is all mounted on brake-pedal support; When stepping on brake pedal, push rod drives elastic contact blade motion by holding motivation structure, thus being switched on or switched off of realizing circuit.Because brake pedal is welded unit, install and foozle larger; Therefore the distance between every chassis brake pedal and braking light switch push rod must be adjusted.At present, normally carry out the distance between regulating pushing rod and brake pedal by the locking nut be located on shell, not only troublesome poeration, efficiency is low, labour intensity is large, and locking nut is once loosen, and easily causes the loose contact between the push rod of switch and brake pedal, can not being switched on or switched off of realizing circuit.
Summary of the invention
For the above-mentioned defect existed in prior art, the utility model aim to provide a kind of mounting and adjusting convenient and swift, can the journey variable formula brake gear of the spacing of regulating pushing rod and brake pedal automatically.
To achieve these goals, the utility model by the following technical solutions: it comprises the shell fixedly docked with base; Be fixed with spring base, big spring, two piece of first contact and two pieces of the second wafers in base, big spring be fixed with the spring cup contacted with two the second wafers; Be fixed with rotation seat in shell, two shifting blocks being fixed on this rotation seat top protrude upward through two kidney slots being positioned at cover top portion; Clutch seat to be inserted from below in rotation seat by external splines and is attached thereto, there is the connecting ring be connected by two first tooth bars the bottom of clutch seat, this connecting ring is flexibly connected with positioning seat by establishing annular groove thereon, and this positioning seat is fixed with the elastic contact blade corresponding with two piece of first contact position; The push rod that inside is fixed with little spring protrudes upward through positioning seat, connecting ring, clutch seat, rotation seat and shell from bottom to top successively; The lower end of little spring holds out against on spring base, push rod outer wall has second tooth bar corresponding with two first rack position.
The inwall of shell there is keyway, the outer wall of push rod has the feather key suitable with this keyway; The top of push rod is fixed with block, and the top of little spring is fixed on this block; Shell is fixed with elastic card.
Compared with the prior art, the utility model owing to have employed technique scheme, therefore have assembling regulate simple and convenient, efficiency is high, can not cause that the distance between push rod and brake pedal changes, good reliability because of vibration.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the perspective view after removing shell and base;
Fig. 3 is the vertical view of Fig. 1.
In figure: push rod 1, little spring 2, rotation seat 3, clutch seat 4, first tooth bar 5, elastic contact blade 6, first contact 7, base 8, big spring 9, spring base 10, spring cup 11, positioning seat 12, shell 13, connecting ring 14, external splines 15, shifting block 16, block 17, feather key 18, the second wafer 19, contact block 20, kidney slot 21.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
As shown in Figures 1 to 3: base 8 is fixedly docked with 13 by the mode of buckle and forms cavity.Spring base 10, big spring 9, two piece of first contact 7 and two pieces of the second wafers 19 are fixed with in base 8, top on big spring 9 is fixed with spring cup 11, this spring cup has two contact blocks 20 be connected as a single entity with it, each contact block 20 contacts with two the second wafers 19 are corresponding respectively.Be fixed with rotation seat 3 in shell 13, two shifting blocks 16 being fixed on this rotation seat top protrude upward through two kidney slots 21 being positioned at shell 13 top, and the inwall of rotation seat 3 has internal spline (not shown); Rotation seat 3 can rotate 90 ° at shell 13.Clutch seat 4 by establish external splines 15 thereon from below the internal spline inserted in rotation seat 3 be attached thereto, clutch seat 4 can move up and down in rotation seat 3; There is the connecting ring 14 be connected by two first tooth bars 5 bottom of the bottom clutch seat 4 of clutch seat 4, and this connecting ring is flexibly connected with positioning seat 12 by establishing annular groove thereon (not indicating in figure); Connecting ring 14 can rotate on positioning seat 12.Positioning seat 12 is fixed with the elastic contact blade 6 corresponding with two piece of first contact 7 position, positioning seat 12 can slide up and down in base 8.Push rod 1 protrudes upward through positioning seat 12, connecting ring 14, clutch seat 4, rotation seat 3 and shell 13 from bottom to top successively, its lower end of little spring 2 be fixed in push rod 1 holds out against on spring base 10, and push rod 1 outer wall has second tooth bar corresponding with two first tooth bar 5 positions.
Engage, the inwall of shell 13 is provided with keyway in order to avoid push rod 1 rotates and causes described tooth bar and the first tooth bar 5 to depart from, the outer wall of push rod 1 has the feather key 18 suitable with this keyway.
For the ease of fixing little spring 2, the top of push rod 1 is fixed with block 17, and the top of little spring 2 is fixed on this block.
For the ease of Fast Installation, simultaneously also in order to avoid loosening because of vibration, shell 13 is fixed with elastic card.
Operation principle: when the utility model is in off-position, push rod 1 is at the highest notch by jack-up under the effect of little spring 2, and clutch seat 4 then holds out against in rotation seat 3 by positioning seat 12, connecting ring 14, first tooth bar 5 by big spring 9; Now push rod 1 slides up and down, and positioning seat 12, connecting ring 14, first tooth bar 5 be transfixion all.When pressing lower push-rod 1 and by rotation seat 3 half-twist, rotation seat 3 just can drive the first tooth bar 5 also half-twist by clutch seat 4, and the first tooth bar 5 engages with described second tooth bar, and the utility model is in service position.
When the utility model is in service position, step on automobile brake pedal (not shown), push rod 1 just can drive connecting ring 14 and positioning seat 12 to move down by the first tooth bar 5.In the process that positioning seat 12 moves down, elastic contact blade 6 just can first contact with two piece of first contact 7, so normally opened contact closes and connects circuit; When positioning seat 12 continues to move down, positioning seat 12 just can be oppressed big spring 9 and make disengaging of spring cup 11 and two pieces of the second wafers 19, so normally-closed contact disconnects and cuts off another one circuit.
