Description

Case and bag roll wheel assembly

Technical field

The utility model relates to a kind of case and bag roll wheel assembly.

Background technology

Existing case and bag roll wheel assembly, comprise outer bracket, support, wheel, Neto, wheel is connected with support, between support and outer bracket, be provided with vertical pivot, support is connected by vertical pivot with outer bracket, the top of vertical pivot is fixedly connected with outer bracket, the axle installing hole that vertical pivot bottom is provided with support top rotatably coordinates, vertical pivot middle and lower part is provided with annular notch, support is provided with horizontal fixing hole, laterally fixing hole is corresponding with the annular notch position of vertical pivot, laterally in fixing hole, be provided with a horizontal fixture, laterally a part for fixture snaps in annular notch and matches with annular notch, while adopting this roll wheel assembly to be used on case and bag, being connected between the casing of case and bag and roll wheel assembly is by outer bracket and Neto, to clamp the inside and outside both sides of bottom half, outer bracket, this three-decker of casing and Neto is fixed by a plurality of screws, thereby roll wheel assembly and casing are fixed, and the external screw thread that is mostly screw finally matches with the internal thread outer bracket through Neto and casing from box inside, in this structure, common outer bracket, casing and Neto are made by non-metallic materials such as plastics or canvas, when case and bag, put and take roll wheel assembly during as touchdown point, roll wheel assembly is subject to the gravity of casing and the support force on ground, roll wheel assembly also has reaction force to casing simultaneously, outer bracket now, stress point between casing and Neto mainly concentrates on several screws, screw and non-metallic material are made outer bracket, the heaviest painstakingly between casing and Neto, on irregular ground, drag case and bag or case and bag by being lifted in the process of putting down, screw outer bracket, easily wearing and tearing or loosening between casing and Neto, and outer bracket, the active force of mutually pullling between casing and Neto is born by the external screw thread of screw and the internal thread in outer bracket, cause wearing and tearing between the internal thread in screw and outer bracket the most serious, after internal thread in outer bracket is worn away by screw, will cause roll wheel assembly to come off from casing, therefore existing case and bag are deposited in use and are connected built on the sand between casing and roll wheel assembly with roll wheel assembly, casing is easily caused to wear out failure, make the defect shortening in service life of casing.

Utility model content

Technical problem to be solved in the utility model is: the case and bag roll wheel assembly that a kind of stable connection,, the long service life that make casing little to casing wearing and tearing are provided.

In order to solve the problems of the technologies described above, technical solution of the present utility model is such: a kind of case and bag roll wheel assembly, comprise outer bracket, support, wheel, Neto, wheel is connected with support, between support and outer bracket, be provided with vertical pivot, support is connected by vertical pivot with outer bracket, the top of vertical pivot is fixedly connected with outer bracket, the axle installing hole that vertical pivot bottom is provided with support top rotatably coordinates, vertical pivot middle and lower part is provided with annular notch, support is provided with horizontal fixing hole, laterally fixing hole is corresponding with the annular notch position of vertical pivot, laterally in fixing hole, be provided with a horizontal fixture, laterally a part for fixture snaps in annular notch and matches with annular notch, described vertical pivot is metal material, vertical pivot is provided with upper end open and to the internal thread hole of downward-extension, described outer bracket is provided with reinforced panel and deputy thread slotted eye, described reinforced panel is enclosed in vertical pivot outer ring, it is corresponding with internal thread hole position that described Neto is provided with main through hole, in Neto, be also provided with secondary through hole corresponding with deputy thread slotted eye position, between outer bracket and Neto, be provided with that main screw matches with the internal thread hole of vertical pivot and secondary screw matches with deputy thread slotted eye.

The beneficial effects of the utility model are: in above-mentioned technical solution, case and bag be take vertical pivot as rotating shaft rotation with roll wheel assembly, vertical pivot bottom is fixed on support by horizontal fixture, vertical pivot top is fixedly connected with outer bracket, thereby case and bag compress casing case and bag are fixed on casing by roll wheel assembly integral body by outer bracket and the Neto of roll wheel assembly, finally realizing casing moves with wheel, adopt the vertical pivot of metal material, and upper end open is set on vertical pivot and to the internal thread hole of downward-extension for being connected with main screw, such structure is in outer bracket, while mutually pullling between casing and Neto, active force each other is mainly born by the internal thread hole on the external screw thread of main screw and the vertical pivot of metal material, not easy to wear between two metalworks, degree of being connected firmly is better, and reinforced panel is set in outer bracket, to be enclosed in vertical pivot outer ring be that the area that contacts while pushing mutually with casing for outer bracket is larger, the pressure producing is less, be difficult for causing the even bursting of wearing and tearing of junction between casing and outer bracket, centered by vertical pivot, distribute and can share more fifty-fifty squeezing action power, arranging that other secondary screw matches with deputy thread hole is in order further to strengthen outer bracket, degree of being connected firmly between casing and Neto, the screw thread of multiple spot dispersion is in the horizontal direction fixing simultaneously can further share active force, to reach stressed uniform effect, with regard to being not easy to cause local pressure, cause local damage like this, extend whole service life, therefore the case and bag that the utility model provides have stable connection with roll wheel assembly, little to casing wearing and tearing, make the feature of the long service life of casing.

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
