Abstract

The utility model discloses a case, mainly comprising a draw rod seat and a case body. The draw rod seat is composed of a draw rod, two idler pulleys and a chassis, wherein the two idler pulleys are respectively arranged under the chassis, the bottom board and sides of the case body are respectively fixed on the chassis and the draw rod. The draw rod seat forms two U-shaped grooves on the chassis, two ends of the draw rod are respectively arranged in the two U-shaped grooves and movably hinged with the chassis. The case body can realize foldable function through changing state of the draw rod and the chassis, which avoids occupied space when the bottom portion of the case body is perpendicular to the draw rod.

Description

A kind of case and bag

The utility model relates to a kind of dilatory case and bag that roll that are used for.

People's business trip or whilst on tour, the case and bag that use can roll on the ground, with laborsaving convenience, the common case and bag that can roll as shown in Figure 1, consist predominantly of a draw-bar seat 1 ' and casing 2 ', draw-bar seat 1 ' by a pull bar 11 ', two rollers a 12 ' and base 13 ' form, base 13 ' both sides form respectively two grooves 131 ', 132 ', the two ends 111 of pull bar 11 ', 112 ' respectively place two grooves 131 ', 132 ' in, fix by rivet; Two rollers 12 ' be located at base 13 ' the bottom.Case and bag 2 ' base plate 21 ' be fixed in draw-bar seat 1 ' base 13 ' on, just form the case and bag that can draw rolling thus.

But the case and bag of said structure, no matter whether adorn thing, owing to be subject to the shape of draw-bar seat, box bottom and side remain plumbness with the side in its bottom, can't fold, so not only the shared space of producer's case and bag in transportation can increase cost of transportation greatly; And the user also is not easy to collection in the family when not using.

The purpose of this utility model provides a kind of folding case and bag, with conserve space.

For achieving the above object, solution of the present utility model is: a kind of case and bag, mainly comprise a draw-bar seat and a casing, draw-bar seat is made up of a pull bar, two rollers and a base, two rollers are located at the base below respectively, and the base plate of casing and side are individually fixed on base and the pull bar, and wherein this draw-bar seat forms two " U " type groove on base, the two ends of pull bar place respectively in two " U " type groove, and are movably hinged with base.

Above-mentioned a kind of case and bag wherein are respectively equipped with limited step in two of draw-bar seat " U " type groove.

Above-mentioned case and bag, wherein the base of draw-bar seat is provided with two positioning seats, and the two ends of pull bar are articulated in respectively on two positioning seats, and two positioning seats are individually fixed in two " U " type groove again.

After adopting such scheme, because the pull bar two ends of the draw-bar seat of case and bag are movably hinged respectively in two " U " of base type groove, then base can be changed to parastate by the plumbness of original and pull bar by hinged member, and the base plate of casing is to be fixed on the base, so, case and bag can realize folding function by the variable condition of pull bar and base, have avoided because the base of draw-bar seat when vertical with pull bar the drawback that case and bag are taken up space.

Below in conjunction with accompanying drawing, specific embodiment of the utility model is described in further detail.

Fig. 1 is a three-dimensional exploded view of commonly using product;

Fig. 2 is the three-dimensional exploded view of the utility model embodiment 1;

Fig. 3 is the three-dimensional exploded view of the utility model embodiment 2;

Fig. 4 is the three-dimensional combination figure of the utility model embodiment 2;

Fig. 5 is the state diagram that folds of the utility model embodiment 2.

As shown in Figure 2, the case and bag of the utility model embodiment 1 consist predominantly of draw-bar seat 1 and casing 2, draw-bar seat 1 is made up of a pull bar 11, two rollers 12 and a base 13, two rollers 12 are located at the bottom of base 13, wherein form two " U " type groove 131,132 respectively, in two " U " type groove 131,132, be respectively equipped with limited step 133,134 (cooperating shown in Figure 3) in the both sides of base 13 and the junction of pull bar 11; The two ends 111,112 of pull bar 11 are movably hinged respectively in two " U " of base 13 type groove 131,132 by hinged member 3; The base plate 21 of casing 2 is fixed on the base 13, and a side 22 of casing 2 is fixed together with the pull bar 11 of draw-bar seat 1.

Shown in Fig. 3,4, be embodiment 2 of the present utility model, be in two " U " type groove 131,132 of draw-bar seat 1 base 13 of case and bag, to be respectively equipped with a positioning seat 135,136, the two ends 111,112 of pull bar 11 are movably hinged respectively in positioning seat 135,136 by hinged member 3, and positioning seat 135,136 is individually fixed in two " U " type groove 131,132 of base 13 again.Can make whole case and bag from seeing hinged member 3 in appearance like this, make product have more associative perception, and be convenient to install from profile.

When these case and bag are collected in transportation or family, cooperate shown in Figure 5, serves as that axle rotates with the pull bar 11 of draw-bar seat 1 with hinged member 3, then pull bar 11 just can change parastate into by original plumbness with base 13, because the existence of limited step 133,134, then pull bar 11 can not rock when being parallel to base 13, and the base plate 21 of casing 2 is to be fixed on the base 13 of draw-bar seat 1 simultaneously, then the base plate 21 of casing 2 just can be folded up to side 22 directions, and realizes space-saving effect.
