Abstract

The utility model relates to a fixing structure for movable castors onto a trunk. The utility model comprises the movable castors which are arranged on the bottom part of a box body. Each of the movable castors is composed of a fixing seat, a foot frame, a bearing and a castor body. The utility model is characterized in that the box body and the fixing seat are correspondingly provided with a pivoting hole for being pivoted with a pivoting seat body. A convex head end of the pivoting seat body is provided with a screw hole, and passes through the pivoting hole corresponding to the fixing seat and the box body. A screwing rod is fixedly screwed in the screw hole of the convex head end by passing through a buffering element and a top supporting sheet. The utility model has the effects of strengthening the structural strength of the trunk and removing and replacing each element of the movable castors.

Description

The fixture construction of the movable wheel of luggage case

The utility model relates to luggage case, refers in particular to the fixture construction of the movable wheel of a kind of luggage case.

The movable wheels 10 of luggage case commonly used as shown in figures 1 and 3.Cooperate rivet 15 to form by holder 11, foot rest 12, bearing 13 and wheel body 14, the corner of holder 11 is provided with fixing hole 111, and rivet 15 passes the bottom of fixing hole rivet clasp in luggage case 20.It is very easily impaired that its major defect is that the bottom of luggage case is subjected to rivet and holder top to compel the place, causes dropping or the luggage case damage of movable wheels; Because its movable wheels are to form with the rivet rivet clasp, so its any member damages, whole movable wheels must be abandoned, cause waste.

The purpose of this utility model is to provide a kind of fixture construction of luggage case activity wheel, by installing buffering spacer and hinging base body and the solid rod member of spiral shell, reaches the detachable purpose of changing of the structural strength of strengthening luggage case and each assembly that makes movable wheels.

The purpose of this utility model is achieved in that the fixture construction of the movable wheel of a kind of luggage case, the bottom installing activity wheels that comprise casing, these activity wheels are made up of holder, foot rest, bearing and wheel body, it is characterized in that this casing and holder correspondence are provided with the pivot hole and are pivoted for the hinging base body, the plush copper end of this hinging base body is provided with screw, this plush copper end passes through the pivot hole of this holder and casing correspondence, and the solid rod member of spiral shell passes bolster and the support sheet is fixed in the screw of this plush copper end; Be provided with cushion pad between the bottom of this holder and casing; Many places between this holder and the casing cooperate fixing with screw and buffering spacer.

Major advantage of the present utility model is the detachable effect of changing of each assembly that has the structural strength of strengthening luggage case and make movable wheels.

Below in conjunction with preferred embodiment and accompanying drawing the utility model is further specified,

Fig. 1 is the decomposing schematic representation of common structure;

Fig. 2 is the combination schematic diagram of common structure;

Fig. 3 is the A portion enlarged diagram of Fig. 2;

Fig. 4 is a decomposing schematic representation of the present utility model;

Fig. 5 is a combination cross-sectional schematic of the present utility model.

Consult Fig. 4-Fig. 5, the utility model comprises the bottom installing activity wheels 30 of casing 20, these activity wheels 30 are made up of holder 31, foot rest 32, bearing 33 and wheel body 34, it is characterized in that this casing 20 and holder 31 correspondences are provided with pivot hole 21,311 and are pivoted for hinging base body 40, the plush copper end 41 of this hinging base body 40 is provided with screw 42, this plush copper end 41 passes through the pivot hole 311,21 of this holder 31 and casing correspondence, and the solid rod member 60 of spiral shell passes bolster 61 and support sheet 62 is fixed in the screw 42 of this plush copper end 41.Be provided with cushion pad 50 between the bottom of this holder 31 and casing 20.Because the solid rod member 60 of spiral shell is not to directly act on the casing 20 with the clamping power that hinging base body 40 is produced, but by 61 pairs of casing 20 application of forces of bolster, and make the bolster 61 more abundant casings 20 that fit in, indirectly produce a kind of strengthening action of the pivot hole 21 place's structures to casing 20, make the combined structure between movable wheels 30 and the casing 20 more firm.

Because each assembly of movable wheels 30 is to cooperate the pivot knot with solid rod member 60 of spiral shell and hinging base body 40, so when wherein any assembly damages, can so that change the assembly that damages, each assembly of movable wheels 30 be played one's part to the full movable wheels 20 dismountings.Any place between this holder 31 and the casing 20 cooperates fixing with most screws 70 and buffering spacer 71, further improve the structural strength that holder 31 combines with casing 20.

Claims
