Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-7, the present invention provides an embodiment:

the utility model provides a capable car of key receipts, including capable car body 1 and bayonet lock 340, it includes down violently pipe 110 to help car body 1, the top of violently managing 110 down is connected with support tube 120, the top of going up support tube 120 is connected with supporting pad 130, the inner wall connection of going up support tube 120 has the crossover pipe 140, the end-to-end connection of going up support tube 120 has fixedly connected with coupling mechanism 2, coupling mechanism 2 includes main part connecting piece 210, the terminal fixedly connected with main part connecting piece 210 of going up support tube 120, connecting clamping groove 220 has been seted up to the inside of main part connecting piece 210, the inside of violently managing 110 down runs through there is brake interior line 230, the internally connected with fastening device 3 of violently managing 110 down, fastening device 3 includes base 310, the internally connected with base 310 of violently managing 110 down, the inside embedding of base 310 is connected with reset spring 320, one side fixedly connected with synchronous carousel 330 of base 310.

Further, the lower transverse tubes 110 and the upper supporting tubes 120 are provided with two groups, the two groups of lower transverse tubes 110 and the upper supporting tubes 120 are connected through the cross tubes 140, and the stability of the walking aid vehicle is improved through the design of the two groups of lower transverse tubes 110 and the upper supporting tubes 120, and the walking aid vehicle is more stable when being pushed.

Further, the cross pipes 140 are cross-connected, and the cross pipes 140 are connected by means of hinge shafts, and the two sets of lower cross pipes 110 and the upper support pipes 120 are connected to each other by means of the connection of the hinge shafts.

Further, the main body connecting piece 210 is arc-shaped, the main body connecting piece 210 is matched with the inner wall of the lower transverse pipe 110, the connection stability is improved after connection is completed through tight connection between the lower transverse pipe 110 and the main body connecting piece 210, connection is firmer, and the problem of shaking after connection is avoided.

Further, circular shape recess has been seted up to base 310's inside, and bayonet lock 340 and reset spring 320 all imbed in the inside of recess, and synchronous turntable 330 passes through the loose axle to be connected on base 310, and when bayonet lock 340 embedding was in base 310's inside, realized that the secondary between violently managing 110 and the last stay tube 120 of lower tube is accomodate, and the mode of accomodating like this can have reduced the occupancy in space greatly.

Further, the return spring 320 is inserted into the synchronous turntable 330, one end of the return spring 320 is fixedly connected with a bayonet 340, and the angle of the synchronous turntable 330 is deflected through the brake inner wire 230, so that power output is realized.

The working principle is as follows: when carrying out once folding and accomodating the operation, through being close to each other between lower horizontal pipe 110 and the last stay tube 120, once accomodating has been realized, the colleague that is close to each other between lower horizontal pipe 110 and last stay tube 120 has driven the cross tube 140 and has taken place to deflect with the angle, when the contained angle that cross tube 140 formed is close to coincidence, once accomodating has been realized, when carrying out the operation of accomodating from folding, through pulling brake interior line 230, the angle deflection of synchronous dial 330 has been driven, will drive bayonet lock 340 to the inside shrink of base 310 when the angle of synchronous dial 330 takes place to deflect, will make bayonet lock 340 and connection slot 220 separate between the inward shrink when bayonet lock 340, at this moment make the angle of lower horizontal pipe 110 and last stay tube 120 take place to deflect through buckling last stay tube 120, and then the secondary accomodating of realization, at the place in-process of accomodating, need not carry out the operation of bowing.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
