The baby carrier is an indispensable toy for children's life, particularly, a three-wheel baby carrier is most favored by children, the height of the supporting feet of the existing three-wheel baby carrier is generally not adjustable, however, the baby carrier with the height not adjustable is not suitable for playing along with the height of the children or the use of the children at different ages at home; the height of the supporting legs of the existing part of the baby carriage can be adjusted, the supporting legs of the existing part of the baby carriage comprise an outer tube, an inner tube and a spring pin arranged in the inner tube, a spring part of the spring pin is arranged in the inner tube, and a pin head penetrates through a through hole of the inner tube and then is clamped in an adjusting through hole of the outer tube; many people can think of using the bolt to pass the through-hole of inner tube, outer tube both sides simultaneously and fix interior outer tube in the life, but do not set up the bolt head of bolt handle one end and hardly fix with other article, make the bolt can not break away from the through-hole of interior outer tube, if the bolt head with the through-hole interference fit of interior outer tube, the bassinet also makes the bolt break away from the through-hole of interior outer tube after riding the vibration easily.

Disclosure of Invention

In view of the defects of the prior baby carriage supporting leg, the utility model aims to solve the technical problems that: the supporting leg adjusting device for the baby carrier is better in stability.

In order to achieve the above object, according to one aspect of the present invention, the present invention is achieved by the following technical measures: the utility model provides a bassinet supporting legs adjusting device, includes supporting legs and mounting, the supporting legs cup joint the scalable supporting legs of constituteing for inner tube and outer tube, the inner tube both sides respectively be equipped with one row of regulation through-hole that corresponds each other, the outer tube respectively is equipped with a through-hole that corresponds each other with the one end both sides of inner tube connection, the mounting include cyclic annular buckle and round pin axle, cyclic annular buckle one side opening, and open-ended width is less than supporting legs outer tube diameter, round pin axle one end fix in cyclic annular buckle, the other end passes cyclic annular buckle opening center and extends out outside the opening, the round pin axle interlude the regulation through-hole that outer tube through-hole and inner tube make inner tube and outer tube fixed, cyclic annular buckle closely encircle outside the outer tube.

Furthermore, two ends of the annular buckle opening are respectively outwards rolled with a flange.

Furthermore, the outer side of the annular buckle at the fixing position of the pin shaft and the annular buckle is provided with a fixing part which protrudes outwards.

Compared with the prior art, the utility model has the advantages that: the fixing piece is composed of an annular buckle and a pin shaft, the two ends of the opening of the annular buckle slide through the outer tube of the supporting leg and then tightly surround the outer tube of the supporting leg, and the pin shaft can be firmly fixed by the annular buckle so as to prevent the pin shaft from being separated from the adjusting through hole and the through hole of the inner tube and the outer tube of the supporting leg and causing danger.
