[specific embodiment]

The utility model is further described in detail with reference to the accompanying drawings of the specification:

As shown in Figs. 1-5, one kind pushing away trailer, including wheel carrier 1, and wheel carrier 1 is equipped with liftable seat 2 and being capable of edge Push rod 3 of the sliding of wheel carrier 1 to drive seat 2 to go up and down, push rod 3 can be folded to wheel carrier 1 and seat 2 in sliding process Between or rotation erect, the locking structure 4 that can limit the sliding of push rod 3 is equipped between push rod 3 and wheel carrier 1, push rod 3 is equipped with The tripper 5 of the limitation of locking structure 4 can be unlocked.Further, push rod 3 is slided along front and back wheel moving direction.

Wheel carrier 1 includes the connecting rod 11 of connection front and back wheel, and connecting rod 11 is equipped with the sliding seat 6 that can be slid along, push rod 3 It is rotatably coupled sliding seat 6.Close with wheel carrier 1 when low level is down at seat 2, push rod 3 is folded in wheel carrier 1 and seat 2 Between, can stand great Tong or pet on seat 2.When seat 2 rises, push rod 3 can turn to push-and-pull position, convenient for pushing away Trailer.

Preferably, tripper 5 includes unlocking structure 51 and the STATEMENT OF FEDERALLY SPONSORED 52 for connecting unlocking structure 51 and locking structure 4. It is highly preferred that STATEMENT OF FEDERALLY SPONSORED 52 is linkage rope or interlocking bar.

Push rod 3 is rotatably coupled by locking structure 4 with sliding seat 6.Locking structure 4 includes the pedestal of connection push rod 3 41, which is equipped with the axle sleeve 42 of socket sliding seat 6, and axle sleeve 42 can rotate in sliding seat 6 realizes turning for push rod 3 It is dynamic, the positioning pin 43 that can be stretched out 42 one end of axle sleeve or retract in axle sleeve 42 is arranged in axle sleeve 42, connecting rod 11 is equipped with and positioning Pin 43 cooperates locking seat 2 in the lock hole (not shown) for increasing position.Locking structure 4 can guarantee that seat 2 is rising position The stability set.It communicates in 42 inner cavity of axle sleeve and sliding seat 6, is communicated when lock hole is located in sliding seat 6 with 42 inner cavity of axle sleeve, Positioning pin 43 can be aligned.

Tripper 5 further comprises that the linkage block 53 that STATEMENT OF FEDERALLY SPONSORED 52 and positioning pin 43 are connected in pedestal 41 is arranged in, should Linkage block 53 drives positioning pin 43 to be detached from lock hole under the linkage of STATEMENT OF FEDERALLY SPONSORED 52, to realize that unlock limits the sliding of push rod 3 Position.The shifting that being provided with of linkage block 53 is also beneficial to the axial movement of positioning pin 43 conducive to the installation of STATEMENT OF FEDERALLY SPONSORED 52 is qualitative, and it is fixed to reduce It hinders and is lost caused by when 43 deviation of stroke of pin of position.

Unlocking structure 51 includes the lifting piece 511 for being arranged on push rod 3 and connecting STATEMENT OF FEDERALLY SPONSORED 52, and push rod 3 is equipped with limit The fixing piece 512 of lifting piece 511, be equipped between lifting piece 511 and fixing piece 512 unlock that both can make to connect or separate by Part 513.Unlock, which protrudes into lifting piece 511 by 513 one end of part and can stretch out in 511 outer peripheral surface of lifting piece, forms turret terminal 5131, The other end is the positive stop end 5132 of inverted T-shaped and protrudes into fixing piece 512, and 5121 He of solution locked groove communicated is equipped in fixing piece 512 Lock slots 5122, solution 5121 length of locked groove are greater than lock slots 5122, and preferably unlock is by the positive stop end 5132 of part 513 in solution locked groove 5121 stroke is inserted into the length of lock hole not less than positioning pin 43.It is highly preferred that unlock is by between part 513 and lifting piece 511 Equipped with the return unit 514 resetted convenient for unlock by part 513, return unit 514 can be applied unlock by part 513 for reed or spring-like Add reaction force.

Further, positioning pin 43 is equipped with the elastic component 44 of axial pressure positioning pin 43 far from one end of corresponding lock hole, Lock hole locking push rod 3 is inserted it into convenient for sliding into the positioning pin 43 that automatically resets when lock hole next time, elastic component 44 is preferred Spring.

Preferably, axle sleeve 42 has axial slide 421, and linkage block 53 is set in the periphery of axle sleeve 42, and linkage block 53 passes through Pin 54 across axial slide 421 is connect with positioning pin 43, and positioning pin 43 is driven to move in the stroke of axial slide 421 It is dynamic；Further, the length of axial slide 421 is consistent by stroke length of the part 513 in solution locked groove 5121 with unlock, avoids Positioning pin 43 is displaced excessively to be caused to damage firmly to sliding seat 6 and elastic component 44.

Further preferred embodiment, connecting rod 11 are two, and sliding seat 6 and lock hole are respectively two, positioning pin 43 phases should be two, be separately positioned on the both ends of axle sleeve 42, and elastic component 44 is arranged between two positioning pins 43.When connecting rod 11 is At two, lock hole is respectively arranged on each 11 inside of connecting rod, and positioning pin 43 is between two connecting rods 11；When connecting rod 11 is one When, lock hole is respectively arranged on 11 liang of outsides of connecting rod, and two positioning pins 43 lock push rod 3 with outside and lock hole.

In the utility model, the free end of the hinged push rod 3 of the bottom end at seat 2, the other end of 2 bottom of seat or in Portion passes through the middle part of the hinged push rod 3 of elevating lever 7, the hinged seat 2 in 7 one end of elevating lever, the hinged push rod 3 in middle part, other end articulator Wheel carrier 1 forms deformable X-shaped structural support seat 2 with push rod 3.

Further, push rod 3 is scalable, and free end is equipped with handle 31, and seat 2 is equipped with part and surrounds or all surround The handrail 21 at seat 2.As described in figures 1 and 5, when handrail 21 surrounds seat entirely, safety coefficient is more preferable, is suitable for little Tong；When helping When 21 part of hand surrounds seat 2, handrail 21 and handle 34 are opposite, as shown in Figure 6.In this way, after great Tong is seated at seat 2, it is preceding to help Hand 21, after there is handle 34 to work as backrest, be not easy to fall safely.

When seat 2 is located at low level, sliding seat 6 is located at the front end of wheel carrier 1, push rod 3 be folded in wheel carrier 1 and seat 2 it Between, positioning pin 43 offset in sliding seat 6 with the outer peripheral surface of connecting rod 11 it is in the unlocked state, when needing to rise seat 2, pull Push rod 3 slides, while rotating push-rod 3, rises seat 2, when sliding seat 5 slides into the other end, positioning pin 43 and lock hole pair Position, elastic component 44 make positioning pin 43 be inserted into lock hole locking to stop sliding the position of fixed sliding seat 6, anti-stopping seat under acting on Position 2 declines, and when seat 2 being needed to decline, press unlock allows lifting piece 511 to be detached from fixing piece 512, upward sliding by part 513 Lifting piece 511 drives the retraction of positioning pin 43 to be detached from lock hole, realizes unlock to pull STATEMENT OF FEDERALLY SPONSORED 52 and linkage block 53 Slide push rod 3 declines seat 2, and folds push rod 3 between seat 2 and wheel carrier 1.

The utility model pushes away trailer, can be used alone, as shown in Figure 1；It rides instead of walk cart, can also open as great Tong State or folded state are pulled by connector to be used after trolley, is pulled after trolley in a folded configuration, little Tong can To be seated in trolley, great Tong can stand on seat 2；It is pulled after trolley under 2 raised configuration of seat, great Tong can be sat On seat 2, handle 34 is leaned against, hand steered handrail 21 loosens comfortable and safe.
