Abstract

The utility model relates to a roller design, which is mainly characterized in that a staircase-shaped wheel axle penetrates into a roller shaft hole; both ends of the wheel axle are respectively sheathed with a conventional fixed piece and a washer, and both of the two ends of the wheel shaft are riveted and positioned; the outer side of the roller shaft hole is provided with a proper reinforcing rib and a buckling and supporting seat; then a wheel cover with an annular clamping and stopping strip is inserted and arranged, and an integrated and independent roller assembly is completed. The utility model can be matched with a protecting cover, and the utility model and the protecting cover can be together locked into a selected position of a box body, so that the roller can roll sufficiently and smoothly. The utility model has the advantages of time saving and convenience for assembly and very good efficiency, and can be in perfect fit with the production schedule of the box body.

Description

Roller

The utility model relates to a kind of roller design, and particularly a kind of formation is simplified the independent roller composite structure that is easy to assembly.

Habitual casing roller, as shown in Figure 5, be to establish integrated plastic cement wheel shaft by a shell block, so as to the axis hole that is placed through roller in conjunction with composition, because of plastic roller bearing loads is easily given birth to off-set phenomenon, make roller easily rub the shell block upper limb and can't guarantee smooth and easy rolling, so working life is extremely short, difficult symbol is real practical; Therefore, also the someone provides another kind of roller design, see also shown in Figure 6, it utilizes a predetermined length bolt to cooperate various trifling assembly such as two pads, a fixed plate, a sleeve to supply roller in conjunction with composition, and still establish a wheel cap buckle in the roller outside to seal, but above-mentioned design still is seen in defective, and division is as follows now:

(1) it is trifling that it cooperates each part of roller assembling, and it is sealed fixing to be placed on bolt one by one in regular turn, and it is very low that the scrappy trouble combined efficiency of assembling work utmost point sense is engaged on the historical facts or anecdotes border.

(2) combination of this roller, must follow casing to assemble in the lump finishes, can't independently finish roller assembling in advance, i.e. this roller design is to make bolt penetrate casing shell wall each assembly of socket and placing for roller more earlier, so must roller combination in the lump be enclosed after casing is finished again, so operating type not only influences casing finished product efficient, and make whole assembling work more complicated, be its composite structure not to the greatest extent rationally, can not make roller assemble the stock in advance in order at any time need.

(3) wheel cap covers, mainly be to cooperate embedded hole to make wheel cap be covered in the roller outside with corresponding dummy slider, but since this dummy slider and embedded hole must aligned position be forced into begin the location, be the puzzlement of increase assembling work, also influence its efficiency of assembling, then do not have the anxiety that comes off to consider as chimeric really.

Main purpose of the present utility model is to provide a kind of roller, especially place for roller with a stepped wheel shaft and suitably bestow riveted and can form an independent roller, can set up for the casing Assembly at any time, its not only simple element be easy to the combination, helping efficiency of assembling improves, and suitable stock in case of need, very saves time and save trouble.

Of the present utility model time a purpose is to provide a kind of roller, it is taken turns and is covered with an annular snap and ends bar, cooperate the set button of roller to hold toilet whereby and hold the location in being forced into arbitrarily to form to detain, because annular snap is ended the bar either direction and all can be forced into the location smoothly, so its combine and assemble is more or less freely and rapid, and the packing effect is splendid, and the undirected outer anxiety that comes off is considered.

The utility model is achieved in that

The utility model is particularly simplified at roll wheel assembly, and can independently finish roller assembling, reach more rational and effective improvement of chimeric do with regard to wheel cap, mainly be to utilize a stepped wheel shaft to be placed through the roller axis hole, a habitual fixed plate, a packing ring are respectively established in both sides, and bestow riveted a roll wheel assembly, with seasonal wheel cap establish annular snap end bar for being forced into the roller outside suitably button hold the location, reach the intended purposes that overcomes above-mentioned every defective one by one whereby.

Following conjunction with figs. describes embodiment of the present utility model in detail:

Fig. 1 is an exploded perspective view of the present utility model;

Fig. 2 is a combination stereogram of the present utility model;

Fig. 3 is a combination section of the present utility model;

Fig. 4 is installed in the enforcement illustration of casing for the utility model;

Fig. 5 is the decomposing schematic representation of habitual roller;

Fig. 6 is the decomposing schematic representation of another kind of habitual roller.

As shown in Figure 1, the utility model mainly is made up of a stepped wheel shaft 1, a roller 2 and a wheel cap 3; Wherein:

Stepped wheel shaft 1 has four end differences that differ in

size

11,12,13,14, and is maximum with footpath, second end difference, 12 rank, and the 3rd end difference 13 occupies inferior, and two ends end difference 11,14 is less;

Roller 2 is provided with an axis hole 21, establishes suitably large and small reinforced

ribs

22,23 around these axis hole 21 apertures, and establishes several buttons in inwall and hold seat 24, and the order button is held the inside crook 241 of seat 24 ora terminalis tools;

Wheel cap 3 is established suitable annular snap in a side and is ended bar 31, and this annular snap is ended bar 31 top tools one and enlarged antelabium 311;

Form as above-mentioned assembly, stepped wheel shaft 1 can be penetrated in roller 2 axis holes 21, second end difference 12 is just propped up in axis hole 21 outer walls, and the 3rd end difference 13 stretches into axis hole 21 fully, terminal 14 of end differences stretch out outside the axis hole 21, and be nested with a packing ring 4, again, this wheel shaft 1 front end end difference 11 is placed through the perforate 51 of a habitual fixed plate 5, combination whereby, the two ends of this wheel shaft 1 can be bestowed riveted (shown in Figure 3) respectively and finish the combination location, and then wheel cap 3 is forced into roller 2 outsides, hold seat 24 formation buckles with its annular card article 31 and the button of roller inwall and fix.

Finish as above-mentioned independent axle assembling, can supply casing at any time need and assemble rapidly and finish, but these roller 2 inboards form a standing shape because of the riveted of wheel shaft 1, so can establish a pad in addition covers 6 and adheres on fixed plate 5, pass inwall from casing 8 inboards and pad covers 6 and be locked on the fixed plate 5 for screw 7, make the utility model in conjunction with extremely simple and easy rapid, the suitable practical effect of tool, especially independent Combination Design of the present utility model, be to be suitable for making in a large number riveted assembling in advance to treat the combination needs of casing, so it helps the casing efficiency of assembling to improve.
