Abstract

The invention discloses an adapted roller with no bearing and low noise for luggage. The adapted roller comprises a box body, a box seat, a roller bracket and a roller, wherein the box seat is arranged at the angle part of the bottom end of the box body; the roller bracket is tightly adapted with the bottom end of the box seat; the roller is adapted at the bottom end of the roller bracket; the bottom end of the box seat is adapted with the middle part at the top end of the roller bracket; an outer sleeve table and a connecting shaft sleeve flange at the top end of the roller bracket are respectively clamped in corresponding outer ring sleeve and inner ring sleeve at the bottom end of the box seat; and adapting pins are respectively inserted in corresponding adapting through hole and a sleeved through hole in the middle of the roller bracket and comprise inner hollow screws. The adapted roller disclosed by the invention has a simple structure; the box seat and the roller bracket are made of plastic material, thus the production cost can be reduced; and the adapted roller is free from rusting and has no ball bearing, thus noise generated by rotating the ball can be reduced and a user can be ensured to be more comfortable.

Description

Switching formula case and bag roller

Technical field

The present invention relates to a kind of case and bag parts, relate in particular to a kind of switching formula case and bag roller that does not have bearing, low noise.

Background technology

Increasing roller in the case and bag bottom, make things convenient for the user to drag case and bag effortlessly, has been a kind of proven technique; Existing case and bag and roller generally are to come bonded assembly through ball bearing of main shaft, make things convenient for roller in dragging, freely to turn to the direction of load, because ball bearing of main shaft is the metallic material manufacturing; Noise is big during use; Be prone to get rusty, burn into needs maintenance usually, increases lubricant, increased inconvenience to the user; Patent of invention CN00127508.9 discloses a kind of stainless steel needle bearing that need not apply lubrication oil that is used for case and bag; But it is big that this patent of invention still can't thoroughly solve noise; Be prone to the problem of getting rusty, corroding, therefore, need thoroughly address this problem the major subjects that becomes patent of the present invention.

Summary of the invention

The objective of the invention is to, overcome the above-mentioned defective of prior art, provide a kind of no bearing, noise low, do not need the switching formula case and bag roller of maintenance.

For realizing said purpose; Technical scheme provided by the invention is following: construct a kind of switching formula case and bag roller; Comprise casing, be arranged on the block in bight, casing bottom, with the rolling wheel support of the tight switching in block bottom; Switching is at the roller of rolling wheel support bottom, and said block bottom and rolling wheel support top middle portion are through the switching of shipping and reselling on another market.

Said block center bottom is provided with the outer ring set of switching, inner ring sleeve, and said inner ring sleeve middle part offers the switching through hole.

Said rolling wheel support comprises the overcoat platform of the outer end on top, the connecting bushing flange at middle part, and the middle part of said connecting bushing flange offers and the corresponding socket through hole of the switching through hole of block inner ring sleeve, and this socket through hole bottom offers stepped hole; Said rolling wheel support bottom comprises turning rolls, and this turning rolls bottom offers the roller switching through hole of symmetry.

The overcoat platform on said rolling wheel support top, connecting bushing flange are connected to respectively in the outer ring set, inner ring sleeve of corresponding block bottom, are plugged with in cooresponding switching through hole in center and the socket through hole and ship and resell on another market, empty nail in this is shipped and resell on another market and comprises.

The roller switching through hole of said turning rolls bottom and the through hole at roller middle part are through the switching of shipping and reselling on another market.

Usefulness of the present invention is, and is simple in structure, adopts plastic material to make block and rolling wheel support, can reduce production costs, and non-corrosive, free from ball bearing, the noise that produces in the time of can reducing the ball rotation makes the user more pleasant.

Fig. 2 is a cross-sectional view of the present invention;

Fig. 3 is an exploded perspective view of the present invention.

The specific embodiment

Be further described below in conjunction with accompanying drawing and preferred embodiment concrete technical scheme with regard to switching formula case and bag roller of the present invention.

Consult Fig. 1～switching formula case and bag roller preferred embodiment shown in Figure 3; Comprise the casing (not shown); Be arranged on the block 1 in bight, casing bottom; With the rolling wheel support of closely transferring in block 1 bottom 2, switching is at the roller 3 of rolling wheel support bottom, and said block 1 bottom and rolling wheel support 2 top middle portion are through 4 switchings of shipping and reselling on another market.

Said block 1 center bottom is provided with the outer ring set of switching 12, inner ring sleeve 14, and said inner ring sleeve 14 middle parts offer the through hole 16 of transferring.

Said rolling wheel support 2 comprises the overcoat platform 21 of the outer end on top; The connecting bushing flange 23 at middle part; The middle part of said connecting bushing flange 23 offers and the corresponding socket through hole 25 of the switching through hole of block inner ring sleeve 14, and this socket through hole bottom offers stepped hole 27; Said rolling wheel support bottom comprises turning rolls 28, and this turning rolls bottom offers the roller switching through hole 29 of symmetry.

The overcoat platform 21 on said rolling wheel support top, connecting bushing flange 23 are connected to respectively in the outer ring set 12, inner ring sleeve 14 of corresponding block bottom, are plugged with in the cooresponding switching through hole 16 in center and the socket through hole 25 and ship and resell on another market 4, and this is shipped and resell on another market and 4 is interior empty nail.

The roller switching through hole 29 of said turning rolls 28 bottoms and the through hole at roller 3 middle parts are through 32 switchings of shipping and reselling on another market.

Above-described only is principle of the present invention and preferred embodiment.Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the principle of the invention, can also make some modification and improvement, also should be regarded as belonging to protection scope of the present invention.
