Description

A kind of case and bag

Technical field

The present invention relates to a kind of case and bag, particularly relate to the roll wheel assembly on case and bag.

Background technology

Existing case and bag comprise two or four rolling assembly under casing and casing, wherein roll wheel assembly clamps both sides inside and outside bottom half by outer bracket and Neto, outer bracket, casing and this three-decker of Neto are fixed by multiple screw, thus roll wheel assembly and casing are fixed, and the external screw thread being mostly screw finally matches with the internal thread outer bracket from box inside through Neto and casing, in this structure, usual outer bracket, casing and Neto are made by the non-metallic material such as plastics or canvas, when case and bag put with roll wheel assembly be touchdown point time, 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, now outer bracket, stress point between casing and Neto mainly concentrates on several screw, screw and non-metallic material make outer bracket, painstaking the heaviest between casing and Neto, case and bag or case and bag are dragged by being lifted in the process put down on irregular ground, screw outer bracket, easily wearing and tearing or loosen between casing and Neto, and outer bracket, the active force mutually pullled between casing and Neto is born by the internal thread on the external screw thread of screw and outer bracket, cause wearing and tearing between the internal thread in screw and outer bracket the most serious, after the internal thread in outer bracket is worn away by screw, roll wheel assembly will be caused to come off from casing, therefore existing case and bag exist between casing and roll wheel assembly and connect built on the sand, easy wear out failure, the defect that service life is short.

Summary of the invention

Technical problem to be solved by this invention is: the case and bag providing a kind of stable connection, not easy to wear, long service life.

In order to solve the problems of the technologies described above, technical solution of the present invention is such: a kind of case and bag, comprise casing and two or four rolling assembly, respectively match with a roll wheel assembly in bottom half two corners or four corners, roll wheel assembly comprises outer bracket, support, wheel, Neto, wheel is connected with support, vertical pivot is provided with between support and outer bracket, 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 and frame upper are provided with rotatably coordinates, vertical pivot middle and lower part is provided with annular notch, support is provided with horizontal fixing hole, horizontal fixing hole is corresponding with the annular notch position of vertical pivot, a horizontal fixture is provided with in horizontal fixing hole, a part for horizontal fixture snaps in annular notch and matches with annular notch, outer bracket and Neto are separately positioned on the inside and outside both sides of casing and are fixedly clamped to coordinate with casing and are fixed on casing by overall roll wheel assembly, 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, Neto is also provided with secondary through hole corresponding with deputy thread slotted eye position, be provided with main screw between outer bracket and Neto to match with the internal thread hole of vertical pivot and secondary screw matches with deputy thread slotted eye.

The invention has the beneficial effects as follows: due in above-mentioned technical solution, case and bag comprise casing and roll wheel assembly, roll wheel assembly take vertical pivot as axis of rotation, vertical pivot bottom is fixed on support by horizontal fixture, vertical pivot top is fixedly connected with outer bracket, casing compresses thus makes roll wheel assembly be fixed on casing by the outer bracket of roll wheel assembly and Neto, finally realize casing to move 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, when mutually pullling between casing and Neto, active force each other bears primarily of 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 arranging reinforced panel in outer bracket, to be enclosed in vertical pivot outer ring be that area in order to contact when outer bracket extrudes mutually with casing is larger, the pressure produced is less, the junction between casing and outer bracket is not easily caused to wear and tear even bursting, centered by vertical pivot, distribution can share squeezing action power more fifty-fifty, arranging that other secondary screw matches with deputy thread hole is to strengthen outer bracket further, degree of being connected firmly between casing and Neto, the screw thread of multiple spot dispersion is in the horizontal direction fixing simultaneously can share active force further, to reach the effect of uniform force, so just be not easy cause local pressure and cause local damage, extend whole service life, therefore a kind of case and bag provided by the invention have stable connection, not easy to wear, the feature of long service life.

Below in conjunction with the drawings and specific embodiments, the invention will be further described.
