Detailed Description

The invention will be further described with reference to the embodiments shown in the drawings to which:

example 1

As shown in fig. 1-5, a scooter folding chassis, includes footboard 1 and locomotive 2, fixed fixing base 5 that is equipped with on the footboard 1 is equipped with mounting groove 6 on the fixing base 5, 2 one end of locomotive stretches into in the mounting groove 6 and locomotive 2 stretches into between the part of mounting groove 6 and the fixing base 5 through setting up first round pin realization rotation and be connected.

Be equipped with two constant head tanks 8 that set up around locomotive 2 and the rotation junction of fixing base 5 on the fixing base 5, the activity is equipped with can imbed in the constant head tank 8 and can lock locomotive 2 location locking mechanism 9 on fixing base 5, when location locking mechanism 9 is located one of them constant head tank 8, be fold condition between locomotive 2 and the footboard 1, when location locking mechanism 9 is located another constant head tank 8, be the expansion state between locomotive 2 and the footboard 1. The headstock 2 is provided with a toggle piece 10 which can drive the positioning locking mechanism 9 to leave and enter the positioning groove 8, the toggle piece 10 is rotatably arranged on the headstock 2 through a second rotating pin 11, and the headstock 2 is provided with an arc groove 13 which transversely penetrates through the headstock 2 and is arranged around the second rotating pin 11. The toggle part 10 is provided with a through hole 12, two ends of the positioning locking mechanism 9 respectively extend out from two ends of the arc groove 13, the positioning locking mechanism 9 comprises a pull rod 14 sleeved in the through hole 12, the pull rod 14 comprises a first rod body 22 and a second rod body 23, one end of the first rod body 22 is provided with a screw hole, the other end of the first rod body 22 is fixedly provided with a fixed block 15, the second rod body 23 is in threaded connection with the screw hole, the end part, back to the first rod body 22, of the second rod body 23 is rotatably connected with an eccentric wrench 19, the pull rod 14 is rotatably sleeved with two pressing sleeves 16 which are respectively positioned at two sides of the toggle part 10 and can be respectively pressed at two sides of the fixed seat 5, each pressing sleeve 16 comprises a sleeve-joint part 17 capable of being embedded into the positioning groove 8 and a pressing part 18 capable of being pressed on the fixed seat 5, the sleeve-joint part 17 is fixedly connected with the pressing part 18, a spring 21 sleeved outside the pull rod 14 is arranged between the pressing sleeve 16 and the toggle part 10, and the two pressing sleeves 16 can be pressed at two sides of the fixed seat 5 by rotating the eccentric wrench 19. A rubber gasket 20 is arranged between the eccentric wrench 19 and the closer pressing sleeve 16, and the side of the rubber gasket 20 facing the eccentric wrench 19 is a concave spherical surface. The pull rod 14 is divided into two sections of the first rod body 22 and the second rod body 23 which are screwed, so that the pressing sleeve 16 and the spring 21 can be conveniently installed on the pull rod 14 when the first rod body 22 and the second rod body 23 are separated.

The utility model discloses a theory of use as follows:

as shown in fig. 1, the utility model discloses an expanded state, when needing to fold between locomotive 2 and the footboard 1 this moment, only need to rotate the eccentric spanner 19 among the positioning locking mechanism 9, make the eccentric spanner 19 relieve the effect of compressing tightly of cover 16 to fixing base 5, redrive shifting piece 10 rotates around second swizzle 11, shifting piece 10 can drive whole positioning locking mechanism 9 and rotate around second swizzle 11 and make the cup joint portion 17 on compressing tightly the cover 16 break away from in the constant head tank 8, can make locomotive 2 rotate around first swizzle this moment, when positioning locking mechanism 9 rotates to another constant head tank 8 position along with locomotive 2, back drive shifting piece 10 this moment, shifting piece 10 can drive the cup joint portion 17 on two compressing tightly covers 16 in the positioning locking mechanism 9 to imbed respectively this constant head tank 8 both ends, at this moment, rotate eccentric spanner 19 again, make eccentric spanner 19 compress tightly on rubber packing ring 20, rubber packing ring 20 promotes one of pressing tightly cover 16 and moves towards shifting piece 10, this in-process eccentric spanner 19 can stimulate pull rod 14, pull rod 14 drives another compressing tightly cover 16 and move towards shifting piece, make the compressing tightly 16 move, so that the final compressing tightly cover 16 and can not realize that the final compressing tightly between fixing base 2 and the folding state between the fixing base 2 and the fixing base 2, so when the folding state can not realize because of the locomotive 2 and the handle 2, so the relative position of the locomotive 2, so the fixing base 2 of this moment, so the locomotive 2, so the fixing base 2, so the locking mechanism 2 can not realize the folding state. If the bicycle needs to be unfolded between the bicycle head 2 and the pedal 1, only reverse operation is needed. When eccentric spanner 19 is in the unblock state, spring 21's setting, can drive two and compress tightly cover 16 and dial 10 both sides removal towards respectively, when needs imbed location locking into constant head tank 8, it is more smooth and easy when compressing tightly in the cover 16 on the portion 17 embedding constant head tank 8 that cup joints, can avoid compressing tightly 18 cards in the notch position of constant head tank 8 of the portion 18 that compresses tightly on the cover 16, and if do not set up spring 21, along with the rotation of locomotive 2, it can move towards piece 10 one side along pull rod 14 to compress tightly cover 16, it is possible that the portion 18 that compresses tightly on the cover 16 can remove to constant head tank 8 top, just be unfavorable for compressing tightly in the portion 17 embedding constant head tank 8 that cup joints on the cover 16 this moment.

The utility model discloses in, through rotating the cover outside pull rod 14 and establishing to compress tightly cover 16 and make to compress tightly the mode realization folding location that cover 16 imbeds constant head tank 8, can avoid taking place wearing and tearing between pull rod 14 and the constant head tank 8 lateral wall, and compress tightly cover 16 and rotate the cover and establish on pull rod 14, compress tightly like this that cover 16 touches constant head tank 8's lateral wall when imbedding in the constant head tank 8 and can take place certain rotation to can reduce the wearing and tearing between compressing tightly cover 16 and the constant head tank 8 lateral wall, thereby prolong the life of this structure.
