Based on above-mentioned basic scheme, the present invention also does following optimization and limits and improve:
Said reference mirror adopts liquid minute surface.
On above-mentioned base plate, place, the hole of relative set is provided with the guide collar that is bell mouth shape downwards, and the axis of guide collar overlaps with steel rope direction, to realize the directional tagging to pole.
The other end of above-mentioned steel rope is to turn to and the fastening winding of power wheel by fixed pulley.
Between said reference mirror and outer frame body inner bottom surface, be provided with rubber pad, on the protective cover of reference mirror, be provided with ring-shaped rubber pad.
Below the anti-guard housing of autocollimator, be fixedly installed collar, while putting in place in order to rise in reference mirror, hold out against the protective cover of reference mirror.
The present invention has the following advantages:
1. simple and compact for structure, occupy little space, applicable to the narrow and small year car of interior space.
2. realized reference mirror land after and miscellaneous equipment thoroughly depart from, not disturbed by miscellaneous equipment, reached the object as level reference.
3. reference mirror is packed up rear position below year chassis, and operating personal just can complete reference mirror and tighten up in car body, convenient and reliable.

Drawing reference numeral explanation:
1 handwheel permanent seat, 2 autocollimators, 3 steel ropes, 4 hand wheel nuts; 5 guide collar, 6 poles, the anti-guard housing of 7 autocollimator, 8 fold seals circles; 9 fold seals circle decks, 10 collars, 11 reference mirror rubber pads, 12 outer frame bodies; 13 reference mirror guard collars, 14 cover glasses, 15 supporting legs, 16 reference mirror; 17 outer frame body rubber pads, 18 reference mirror protective covers, 19 motors, 20 power wheels; 21 fixed pulleys, 22 touch switchs, 23 base plates, 24 contacts.
The specific embodiment
This reference mirror lifting mechanism can be arranged on the top, chassis of vehicle, mainly comprises steel rope, motor, power wheel, fixed pulley, base plate, hand wheel nut, guide collar, reference mirror assembly, touch switch, fold seals circle and the anti-guard housing of autocollimator etc.The support of power wheel and mounted motor is fixed on base plate top, and the anti-guard housing of autocollimator is fixed on base plate and vertically passes base plate.Two steel rope one end are connected with the both sides pole on outer frame body, and the other end turns to and the fastening winding of power wheel by fixed pulley; The rotation input end of power wheel is connected with the rotary output axis end of motor.Guide collar is fixed on base plate lower surface, and guide collar axis overlaps with steel rope direction, and it plays directional tagging to the pole of reference mirror assembly.
Reference mirror, outer frame body, fold seals circle deck and the pole that is fixedly installed in outer frame body top form said reference mirror assembly.Reference mirror is placed on outer frame body bottom surface by gravity, and its below is provided with three taper supporting legs, and supporting leg is inserted into respectively in three respective aperture of outer frame body bottom surface, between these three holes and supporting leg, has larger gap.Fold seals circle deck is connected with outer frame body top inner ring.Fold seals circle lower end is connected with this fixed mount, and upper end is connected with the anti-guard housing of autocollimator.
Principle of work of the present invention is as follows.
Transfer reference mirror: unclamp hand wheel nut; Motor forward drives power wheel rotation, the steel rope being wrapped on power wheel moves down through fixed pulley, the both sides pole on rope traction outer frame body top, transfer outer frame body and land gently, in this process, fold seals circle vertically launches, and the supporting leg of reference mirror bottom is kiss the earth first, along with outer frame body lands, the relative jack-up of reference mirror in outer frame body, reference mirror and outer frame body depart from, and are not subject to the impact of outer frame body.
Promote reference mirror: motor reversal, power wheel drives steel rope to move upward, and the both sides pole on rope traction outer frame body top promotes outer frame body, and positions motion upward by guide collar exit skirt.When outer frame body rises to desired location, the contact probe that outer frame body top arranges touches touch switch, and motor stops operating, outer frame body stop motion.At this moment, with hand wheel nut, pole the screwing of docking is fixed tightly on base plate.In the process of tightening, the slow upward movement of outer frame body just can make it tighten up after the protective cover that is positioned at the collar of the below of the anti-guard housing of autocollimator and pushes up reference mirror.
For below and promote the process of reference mirror in reference mirror is had to certain flexible buffer, can between reference mirror and outer frame body inner bottom surface, be provided with rubber pad, on the protective cover of reference mirror, be provided with ring-shaped rubber pad.
