Abstract

The utility model relates to a case with folding wheel, wherein the bottom of the case is connected with a wheel frame through a hinge, wheels are installed on the wheel frame, a rubber ball is installed on a supporting frame which is inserted into the rear portion of the wheel frame and is fixed through a rivet, a tension spring is installed on a hinge shaft, two clipping strips and a telescopic spring are movably connected through the rivet and are fixed on the bottom of the case, inserted pins are installed on two sides of the case, since the wheel frame can be folded, the wheels of the case are bigger than wheels of a common wheeled case, can move conveniently on concave and convex uneven road surfaces, and can not scrape the case, when the case is held with hands to get on and off cars, vehicles or stairs, the wheel frame can be folded inwards, small wheels can be respectively locked by the two clipping strips, the length of the case can be effectively shortened, the use is convenient, the structure is simple, and the production is easy.

Description

Band folding wheel case and bag

Affiliated technical field

The utility model belongs to the chest class, relates to a kind of band folding wheel case and bag.

Background technology

The belt wheel case and bag are to fix two steamboats on one side of case and bag bottom, the limit has two case and bag pin to be convenient to stand up in addition, after during use case and bag being tilted to make case and bag pin built on stilts, just can haul mobilely easily, but the wheel of commercially available belt wheel case and bag is less, in dragging, moving difficulty when particularly dragging on rough road surface is simultaneously owing to the overhead low bottom of case and bag is easily spoilt, as adopting than larger wheels, will increase case and bag length, give with portable bring when taking up and down car and boat or stair much inconvenient.

Summary of the invention

Less for overcoming existing belt wheel luggage wheel, the deficiency that moving difficulty and bottom are easily spoilt when dragging on rough road surface, the utility model provides a kind of band folding wheel case and bag.

The technical scheme that its technical problem that solves the utility model adopts is: the end in the case and bag bottom is fixed with two case and bag pin, end connects the wheel carrier of a ∏ shape through hinge in addition, one wheel is installed and through the movable combination of rivet on the wheel carrier, the wheel carrier rear end is provided with a support, one end of support inserts wheel carrier and is fixed by rivet, end is installed a ball in addition, one tension spring is installed on the hinge axis, one end of tension spring stretches in the wheel carrier by the notch of wheel carrier inboard, two wheel middle parts are equipped with two card articles and coil tension spring, and after rivet flexibly connects, being fixed on the case and bag bottom, the case and bag both sides are equipped with latch.

When using wheel, case and bag are tiltedly put to case and bag lid side, two card articles are broken into two with one's hands from wheel, and wheel carrier opens under the effect of tension spring automatically, advances by hauling after the latch locking, because wheel carrier is collapsible, wheel is bigger than the wheel of normal tape wheel case and bag, can be convenient mobile on rough road surface, can not abrade case and bag simultaneously yet, landed by the ball on wheel and the support when standing up case and bag, the frictional force on ball and ground can prevent wheel slippage.

With portable when taking up and down car and boat or stair, withdraw from latch, wheel carrier is inwardly depressed, lock wheel respectively by two card articles, under the coil tension spring effect, card article can not removed from wheel easily, effectively shortens case and bag length, lands by being fixed on two case and bag pin on the case and bag and the rivet on the card article when standing up case and bag.

The beneficial effects of the utility model are: because wheel carrier is collapsible, wheel is bigger than the wheel of normal tape wheel case and bag, can be on rough road surface convenient moving, can not abrade case and bag simultaneously, with about portable the taking when car and boat or stair yet, wheel carrier is inwardly depressed, lock steamboat respectively by two card articles, effectively shorten case and bag length, easy to use, simple in structure, be easy to produce.
