It will be fixedly connected, roll up with the knob 1 positioned at the opposite side of valve seat 2 positioned at the driving gear 31 of the side of valve seat 2 and spacing ring washer 35
Receive device 33 and driven gear 32 is rotatably coupled on support 5 by stud 7.
Rubber ring 22 is provided with the flange bottom of valve seat 2, it is convex to damping, valve seat 2 when valve body is attached on car door
It is also connected with being provided with bonnet 23 on edge, effectively protects emergency valve not by external interference and produce potential safety hazard.Also installed on valve seat
There is warning device 24, when bonnet 23 is in opening, warning device on valve seat 2 will be touched and alarmed, so as to prompt
Driver's bonnet is 23 no because being opened accidentally, and effectively prevent the potential risk of vehicle operation car door opening.
The limited post 11 of screw 12 and one is provided with the base of knob 1, spacing ring washer 35 is simultaneously provided with a spacing hole
352, the spacing hole 352 is arranged to blind hole, and the heart offers centre bore 353 wherein, and two are also symmetrically arranged with along centre bore 353
Individual circular groove 351, the grafting of limited post 11 on knob 1 is entered in the spacing hole 352 on spacing ring washer 35, so as to realize knob
1 and the synchronous axial system of spacing ring washer 35, two round steel balls are provided with two circular grooves 351 of spacing ring washer 35
34, the another side of steel ball 34 abuts against with the spring 36 being arranged in valve seat 2, and the lower section of knob 1 sets a big flexible member 9, the bullet
Property one end of element 9 is set on the base of knob 1, and the cavity of the other end and valve seat 2 offsets, and stud 6 sequentially passes through driving gear
31 centre bores, the screw 12 on the centre bore and knob base of spacing ring washer 35, driving gear 31 and knob 1 have been connected
Come, because the connection of the spacing hole 352 on the base upper limit column 11 of knob 1 and spacing ring washer 35, and stud 6 and knob bottom
The cooperation of screw 12 on seat so that driving gear 31 and spacing ring washer 35 can rotate with the rotation of knob 1.
The one side of driven gear 32 and the one side of coiler 33 are linked into an integrated entity by gluing, and cause driven gear
32 and coiler 33 axis overlap.The cylindricality screw 54 of a protrusion is provided with support 5, by the driven gear 32 and retracting
The centre bore of device 33 is sheathed on the cylindricality screw 54, by stud 7 through centre bore opposite side by coiler 33 and driven
Gear 32 is connected on cylindricality screw 54, so that it is connected with support 5, pad 37 is placed between stud 7 and coiler 33,
So that coiler 33 and driven gear 32 are rotatably coupled on cylindricality screw 54, driving gear 31 is with being connected to cylindricality screw
Driven gear 32 on 54 is meshed, so as to enter action edge transmission.The number of teeth of driving gear 31 is 18, the number of teeth of driven gear 32
For 36, the gearratio of change-speed gearing is 2:1, due to output torque=input torque * gearratios, so as to may be such that driven gear
32 output torques, which expand, to be twice, and can be carried out turning knob 1 using smaller power and coiler 33 is obtained bigger torque to roll up
Silk 4 is reeled, so that coiler 33 can be easier to pull wire drawing 4, substantially improves the problem of traditional emergency valve is difficult to rotate.
