See figure 1 – Fig. 8, the convertible using method of marking time of a kind of above-mentioned commercial vehicle/comm..vehicle, this using method comprises marking time to put down step and mark time packs up step;
Described marking time is put down step and is referred to: first with pin, foot operation is indulged the inside that block 31 pushes the vehicle body connecting portion 1 of hollow vertically, foot operation is indulged block 31 brought into motion bar 32 and is inserted vehicle body connecting portion 1 further, spring 33 sheathed on moving lever 32 is compressed, simultaneously, moving lever 32 drives slot to pitch 36 and moves ahead, until groove 44 enters the inside of wide mouth fork 35, now, under the effect of pedal 2 gravity, pedal 2 drives rotating shaft 4 to be rotated down along cw, and fasten until rotating shaft 4 and wide mouth pitch 35, pedal 2 no longer continues to be rotated down, now, mark time and be in down state;
Described marking time is packed up step and is referred to: after pedal 2 is finished using, first trigger pedal 2 with pin to rotate up along conter clockwise, pedal 2 drives rotating shaft 4 along left-hand revolution, when rotating shaft 4, when wide mouth fork 35 departs from fastening state gradually, foot operation is indulged block 31 and is outwards ejected by spring 33 vertically, the foot operation of outer bullet indulges block 31 brought into motion bar 32 layman, the moving lever 32 of layman drives wide mouth to pitch 35 layman, until when groove 44 is positioned at slot fork 36 inside, slot fork 36 fastens with groove 44, the left-hand revolution of rotating shaft 4 terminates, simultaneously, pedal 2 is fixed in rotating shaft 4 makes it not rotate up along conter clockwise again, now, mark time and be positioned at collapsed state.
Described marking time is put down in step, when rotating shaft 4 and wide mouth pitch 35 fasten time, the angle that rotating shaft 4 rotates clockwise is 90 degree;
Described marking time is packed up in step, and when slot fork 36 fastens with groove 44, rotating shaft 4 is 90 degree along the angle of left-hand revolution.
Principle of the present invention is described as follows:
Time to be used: see figure 1 – Fig. 5, now mark time and be in collapsed state, rotating shaft 4 passes radially through vehicle body connecting portion 1(hollow structure, can be the square steel tube on automobile battery framework, U-shaped channel-section steel or self-control support etc.) on shaft hole 11, rotating shaft limiting section 41 is stuck on the outer wall of vehicle body connecting portion 1, rotating shaft connecting portion 43 is fixedly connected with the rotation hangers 21 that pedal 2 is arranged, rotating shaft pars intermedia 42 is positioned at the inside of vehicle body connecting portion 1, the groove 44 that it is arranged is pitched 36 with its outside sheathed slot and is fastened, slot fork 36, wide mouth fork 35, fixed block 34 is all positioned at the inside of vehicle body connecting portion 1, fixed block 34 is fixedly connected with the fixed orifice 12 that vehicle body connecting portion 1 is arranged, spring 33, foot operation indulges the outside that block 31 is all positioned at vehicle body connecting portion 1.Now, can not rotate to make rotating shaft 4 because slot fork 36 blocks groove 44, thus, rotating shaft 4 can overcome the impact of pedal 2 gravity, to avoid pedal 2 to fall along its gravity direction, thus is in the state of packing up.
Putting down marks time refers to: see Fig. 2, 3, 4 and Fig. 6, when using, first with pin, foot operation is indulged the inside that block 31 pushes the vehicle body connecting portion 1 of hollow vertically, foot operation indulges the inside that block 31 brought into motion bar 32 inserts vehicle body connecting portion 1 further, spring 33 sheathed on moving lever 32 is compressed, simultaneously, moving lever 32 drives slot to pitch 36 and moves ahead, maximum open height due to slot fork 36 is less than or equal to the minimal openings height of wide mouth fork 35, thus, groove 44 can fall back and enter the inside of wide mouth fork 35, maximum open height due to wide mouth fork 35 is greater than the spacing between two grooves 44, thus when groove 44 enters wide mouth fork 35 inside, wide mouth fork 35 no longer can block groove 44, rotating shaft 4 is no longer limited, under the impact of pedal 2 gravity, pedal 2 falls along clockwise direction, and drive rotating shaft pars intermedia 42 to be rotated in a clockwise direction, diameter due to rotating shaft pars intermedia 42 is more than or equal to the maximum open height of wide mouth fork 35, thus when rotating shaft pars intermedia 42 rotates through certain angle, when being generally 90 degree, the sidepiece of rotating shaft pars intermedia 42 and wide mouth are pitched 35 and are fastened, make wide mouth pitch 35 and just in time can clamp rotating shaft pars intermedia 42, thus overcome the bounce of spring 33 and the impact of pedal 2 gravity, pedal 2 is made no longer to continue to be rotated in a clockwise direction, now, pedal 2 is in the state put down.In addition, when pedal 2 is rotated down along cw, rotate the other positioning plate 22 arranged of hangers 21 to its also limited location effect, namely cross bar 6 blocks positioning plate 22 and continues to be rotated in a clockwise direction to hinder it, thus restriction pedal 2 continues to be rotated in a clockwise direction.
Packing up marks time refers to: after finishing using, see figure 1 – Fig. 5, hook dynamic pedal 2 with pin to rotate up along conter clockwise, pedal 2 drives rotating shaft pars intermedia 42 along conter clockwise contrarotation through rotating shaft connecting portion 43, rotating shaft pars intermedia 42, wide mouth fork 35 departs from fastening state gradually, now, wide mouth fork 35, engaging power between rotating shaft pars intermedia 42 cannot overcome the bounce of spring 33, foot operation is indulged block 31 and is outwards ejected by spring 33 vertically, the foot operation of outer bullet indulges block 31 brought into motion bar 32 layman, the moving lever 32 of layman drives wide mouth to pitch 35 layman, until when groove 44 is positioned at slot fork 36 inside again, slot fork 36 engages again with groove 44, the left-hand revolution of rotating shaft pars intermedia 42 terminates, its left-hand revolution certain angle, be generally 90 degree, thus the pedal 2 rotated up is fixed by rotating shaft 4, it is made not rotate up along conter clockwise again, now, pedal 2 is positioned at collapsed state, pedal 2 is perpendicular with vehicle body connecting portion 1.
