The safe spacing block 205 of 202 starts unblock, therefore, when vehicle frame is unlocked folding, it is necessary to which first sideslip safety switch 204, makes
Obtain safe closing piece 203 and produce dislocation with safe spacing block 205, then just pressable unlocks briquetting 202 so that unlock briquetting 202
Relative solution lock housing body 201 is slided, and unblock briquetting 202 one end both sides then pull joint unlock piece 206, joint unlock piece 206 simultaneously
Lower end then acts on cooperating joint 4 and unlocked, jackknife action, thus with it is safe and reliable the characteristics of.
As depicted in figs. 1 and 2, bar 31 is had between the bottom of push rod 3 described in two, the front end of front foot pole 8 described in two
Between be provided with pedal 81, fluffy gear pole 47 is had between cooperating joint 4 described in two.
As shown in figure 14, when the utility model is folded, first sideslip safety switch 204 so that safe closing piece 203 and peace
Full limited block 205 produces dislocation.
Then being unlocked by pressing briquetting 202 so that the relative solution lock housing body 201 of unblock briquetting 202 is slided, and unlocks briquetting 202 1
Both sides are held then to pull joint unlock piece 206 simultaneously.
Then the lower end of joint unlock piece 206 then pulls top pressure sliding block 45, and top pressure sliding block 45 is slided along top pressure inclined-plane 451, and
The top pressure tooth block 44 with respect to the projection of upper joint block 41, tooth block 44 then departs from the teeth groove 43 on upper joint block 41.
Promote handle 5 forward with a power immediately, handle 5 is turned down forward with respect to push rod 3, and upper joint block 41 is then with respect to hypozygal
Block 42 is around its axis of rotation, the unblock spigot surface 462 of upper joint block 41 then pushing tow guide cylinder 464 so that solution lock slide 461 edge
Tooth block chute 441 and towards the central slide of tooth block 44, solution lock slide 461 then direct pull unblock STATEMENT OF FEDERALLY SPONSORED 463, lower end then overcomes
Lock the elastic force of return springs 108 so that the free end of locking piece 107 departs from lock hole 102, now, locking mechanism 10 is real
Now unlock, seat bar 9 is slided with respect to push rod 3, and the rear end pushing tow linkage pole 7 of push rod 3, the lower end of linkage pole 7 then pulls front foot
The folding of foot lever 2 backwards of bar 1 is drawn close, while the lower end of the upper end pushing tow push rod pole 6 for pole 7 of linking so that the upper end of push rod 3
The folding of foot lever 2 backwards is drawn close, and realizes synchronous folding mechanism.
