Abstract
The utility model relates to a wheel carrier structure of rollers of transverse pull door, in particular to a wheel carrier structure of rollers arranged below transverse pull metallic door. The utility model is characterized in that: a transverse gap is arranged on the wheel carrier below door body, which supports the wheel axle of the rollers; a part, in which the inner end of the gap supports the wheel axle, is designed to an upward concave so that while replacing or maintaining the rollers, the wheel axle with a bearing axle is brought in or out of the wheel carrier transversely and thus, the utility model achieves the results of convenience, saving time and greatly improving work quality while in assembly and disassembly.
Description
The roller wheel carrier structure of a kind of cross pulling door of the utility model belongs to the sliding door accessory.
At present, the employed metal cross pulling door of tradition, because volume weight is very heavy, so must be by thereunder installing a plurality of rollers, and the track route that moved through by roller, set in advance slide rail, roller can be rolled across the slide rail top, so that the switching motion of push-and-pull operation metal door is easier to be laborsaving, still, because roller is after a period of time of rolling, rolling wheel wear or stuck is always arranged, causing rolling has some setbacks, or even the phenomenon of can't rolling, fault rate is very high.
The roller wheel carrier structure of a kind of cross pulling door of the utility model, its objective is, be convenient to change or safeguard the roller of cross pulling door, the wheel shaft with bearing directly laterally can be operated on wheel carrier, more save time conveniently and have loading and unloading, can significantly improve effects such as work quality again.Be provided with a stopping surface radially at roller corresponding to the bearing place, so that preventing has the axially displaced phenomenon of mutual generation each other between bearing and the roller, it is more stable smooth and easy that roller is turned round, and then effectively prolong the application life of this wheel shaft and bearing, reduce fault rate, increase economic efficiency.
The roller wheel carrier structure of a kind of cross pulling door of the utility model is the wheel carrier that is fixed on cross pulling door door body below by at least one; One is positioned at the roller of above-mentioned wheel carrier; A wheel shaft that penetrates in the roller; A washer that is inserted in by the outstanding wheel shaft in wheel carrier two outsides; Formed with an assembly such as nut that is screwed on the wheel shaft of giving prominence to by wheel carrier two outsides:
This wheel carrier is one " " shape plate body, and in its two parallel plate one side, installing one can be for the breach of wheel shaft embedding;
This roller is positioned at above-mentioned wheel carrier, the center hub two ends bearing that embeds out of the ordinary;
The bearing that this wheel shaft must penetrate in the above-mentioned rollers and embed closely combines mutually, and two ends respectively have the threaded portion that can screw togather mutually with above-mentioned nut.
Wherein, above-mentioned this wheel carrier is one " " shape plate body, in its two parallel plate one side, has laterally installed a breach, and to fovea superior, being one can be for the recess of above-mentioned wheel shaft embedding in this breach the inner.
Wherein, above-mentioned wheel shaft is positioned on the axle of above-mentioned two bearing outsides, convex with the clasp ditch that a flange and can be fastened by clasp, extend the wheel shaft position in above-mentioned flange and the clasp outside, just correspond to the indentation, there of above-mentioned wheel carrier, be that design is the support sector that is slightly less than its diameter of axle, this support sector position of mat is packed with in the recess of breach the inner of stating wheel carrier, makes the threaded portion of its two end be projected into above-mentioned wheel carrier two outsides.
The roller wheel carrier structure of a kind of cross pulling door of the utility model, its advantage is as follows:
1, roller adopts the laterally movable mode of operation that embeds combination or take out, and making all very conveniently in change the outfit combination or the maintenance to save time again.
2, roller is corresponding to the bearing place, and design has a stopping surface radially, and can prevent really has the axially displaced phenomenon of mutual generation between this bearing and the roller each other.
3, structure is made simply, does not increase any material and manufacturing cost at all, also need not change the construction assembling mode, easyly on constructing operation saves time again.
4, can effectively increase the application life of bearing, reduce fault rate, and have more firm effect.
The utlity model has following accompanying drawing:
Fig. 1 is the three-dimensional decomposition texture schematic diagram of the utility model embodiment.
Fig. 2 is the side combining structure schematic diagram of this wound embodiment.
Fig. 3 is the vertical section combining structure schematic diagram of this wound embodiment.
Number in the figure is as follows:
10 wheel carriers, 11 breach, 12 recesses
20 rollers, 21 bearings, 23 stopping surfaces
30 wheel shafts, 31 threaded portions, 32 flanges
33 clasps, 34 washers, 35 nuts
36 support sectors, 37 clasp ditches, 50 guide rails
Now details are as follows for embodiment and conjunction with figs.:
See also as shown in Figure 1 to Figure 3, the roller wheel carrier structure of a kind of cross pulling door of the utility model includes:
One wheel carrier 10, this wheel carrier 10 are one " " shape plate body, are welded on body 40 belows, and two parallel plate one sides at it are horizontally arranged with a breach 11, then upwards are arranged with in these breach 11 the inners to be a recess 12;
One roller 20, center hub two opposite ends embed a bearing 21 respectively, and are positioned at above-mentioned wheel carrier 10, corresponding to bearing 21 places, design has an axial stopping surface 23, between this bearing 21 and the roller 20 the axially displaced phenomenon of mutual generation is arranged each other so that can prevent really;
One wheel shaft 30, can penetrate in the above-mentioned rollers 20 and closely combine mutually with the bearing 21 that embeds, two ends respectively have threaded portion 31, be positioned on the axle of above-mentioned two bearings 21 outsides, then convex with the clasp ditch 37 that a flange 32 and can be fastened by clasp 33 respectively, to prevent that this bearing 21 and roller 20 from producing axially displaced phenomenon, extend wheel shaft 30 positions in the above-mentioned flange 32 and clasp 33 outsides, just correspond to breach 11 places of above-mentioned wheel carrier 10, design is the support sector 36 that is slightly less than its diameter of axle, so that these support sector 36 positions of mat embed in the recess 12 of above-mentioned breach 11 the inners, make the threaded portion 31 of its two end be projected into above-mentioned wheel carrier 10 2 outsides;
One washer (Washer) 34 is inserted on the threaded portion 31 by the outstanding wheel shaft 30 in above-mentioned wheel carrier 10 2 outsides;
One nut 35 is screwed on the threaded portion 31 by the outstanding wheel shaft 30 in above-mentioned wheel carrier 10 2 outsides, and forces above-mentioned washer 34 and wheel carrier 10 lateral surfaces to abut against each other, and this washer 34 of mat is to prevent that the locking effect that gets loose is arranged between nut 35 and this threaded portion 31.
By the structure of above-mentioned each combination of components, can allow roller 20 be placed on the guide rail 50 and roll, be unlikely making bearing 21 or roller 20 on wheel shaft 30, produce axially displaced damage phenomenon.
