Description
Technical field
The utility model relates to track pulley, particularly the pulley of the track such as door such as door, study door.Also relate to the rail system that contains this pulley.
Background technology
The door pulley of prior art comprises pulley and the wheel shaft on wheel carrier, the wheel carrier.General pulley does not all have anti-drop function, install for convenient, the diameter of pulley usually less than on the track opening between the lower edge size, when pulley slide smooth, beat or when running into obstacle, pulley may come off out from the opening part of track.And the pulley of prior art generally only has two wheels, and the weight of door is all born by two wheels, makes the frictional force between pulley and the track large, and it is larger wear and tear, cause pulley and orbital lifetime to be lacked, so the track pulley of prior art requires further improvement.
The utility model content
The purpose of this utility model is to overcome the defects of prior art, and a kind of pulley is provided, this do not take turns can from track, come off, single take turns stressed little and stressed evenly, between pulley and the track wearing and tearing little, the life-span is long.
Another purpose of the present utility model is to provide a kind of rail system that comprises above-mentioned pulley, and this rail system has prevent from taking turns the function that comes off from track, and can make single take turns stressed little and stressed evenly, can prolong pulley and orbital lifetime.
For achieving the above object, the utility model is by the following technical solutions:
The utility model comprises the main wheel on wheel carrier and the wheel carrier, and this main wheel is installed in a side of wheel carrier side by side along the direction of motion of pulley, and jockey pulley also is installed on the wheel carrier, this jockey pulley be positioned at main wheel above or below, main wheel and jockey pulley move in the same way.
Two main wheels are arranged on the wheel carrier.
Two jockey pulleys are arranged on the wheel carrier.
Two horizontal parallel support members are arranged on the wheel carrier, and main wheel and jockey pulley are installed in respectively on the same support member.
Also be connected with movable wheel seat on the wheel carrier.
Movable wheel seat is provided with lid.
The described rail system that comprises above-mentioned pulley, comprise parallel getting on the right track and lower railway, described getting on the right track consists of with the baffle plate of lower railway by rail groove and rail groove top, track also is provided with the opening that stretches into for wheel carrier, described main wheel is placed in one of them track, jockey pulley is placed in another track, the size of the opening of the track that the diameter of main wheel and jockey pulley all is positioned at greater than main wheel and jockey pulley.
As further improvement, the rail groove in described the getting on the right track and the baffle plate of lower railway are integrated.
The beneficial effects of the utility model are: compared with prior art, pulley of the present utility model is two-layer up and down because have main wheel and a jockey pulley, therefore single take turns stressed little and stressed evenly, between pulley and the track wearing and tearing little, the life-span is long.And because main wheel and jockey pulley are the two rows relations, two skates reduce from this probability that comes off of track simultaneously, thereby have reduced the possibility of derailing.
Rail system of the present utility model, because two parallel tracks are arranged, and the size of the opening of the track that all is positioned at greater than main wheel and jockey pulley of the diameter of main wheel and jockey pulley, main wheel and jockey pulley can not be come off out from the track at its place.Simultaneously two tracks carry two skates, have solved the stressed heavy problem of wheel, make single take turns stressed little and stressed evenly, between pulley and the track wearing and tearing little, the life-span of having improved pulley and track.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the explosive view of the utility model pulley;
Fig. 2 is the front view of structure shown in Figure 1;
Fig. 3 is the stereogram of structure shown in Figure 1;
Fig. 4 is the structural representation of the utility model rail system.
The specific embodiment
Fig. 1 illustrates a kind of embodiment of the present utility model, comprise the main wheel 3 on wheel carrier 1 and the wheel carrier, this main wheel 3 is installed in a side of wheel carrier 1 side by side along the direction of motion of pulley, and jockey pulley 4 also is installed on the wheel carrier 1, this jockey pulley 4 be positioned at main wheel 3 above or below, main wheel 3 and jockey pulley 4 move in the same way.The diameter of ordinary circumstance main wheel 3 is greater than the diameter of jockey pulley 4.As preferably, two main wheels 3 and two jockey pulleys 4 are arranged on the wheel carrier 1.
In order to make main wheel 3 relative with the installation site of jockey pulley 4 fixing, flexible type does not have two horizontal parallel support members on the wheel carrier 1, and main wheel 3 and jockey pulley 4 are installed in respectively on the same support member.Fig. 1 illustrates, and main wheel 3 is installed on the lower support element 11 by screw 31, and jockey pulley 4 is installed on the upper supporting piece 12 by screw 41.This structure, main wheel 3 is relative with the position of jockey pulley 4 fixing, after use is long-time, can modification yet.
For pulley being used and in the bending track, also being connected with movable wheel seat 2 on the wheel carrier 1.Movable wheel seat 2 is flexibly connected with wheel carrier 1.This connection can be the general connected mode of the art, such as hinged or pivot joint.See Fig. 1, movable wheel seat 2 is articulated on the wheel carrier 1 by bolt 22 and nut 23.For attractive in appearance, behind movable wheel seat 2, be equipped with and cover 5, lid 5 is installed on the movable wheel seat 2 by screw 51.
As shown in Figure 4, the rail system 6 that comprises above-mentioned pulley, described rail system 6 comprises also that up and down two parallel are got on the right track 62 and lower railway 61, wherein gets on the right track 62 to be made of get on the right track groove 621 and baffle plate 622, gets on the right track 62 also to be provided with the opening 623 that stretches into for wheel carrier 1.Lower railway 61 is made of lower railway groove 611 and baffle plate 612, and lower railway 61 also is provided with the opening 613 that stretches into for wheel carrier 1.Described main wheel 3 is placed in the lower railway 61, and jockey pulley 4 is placed in and gets on the right track in 62.The opening 613 of the track that the diameter of main wheel 3 and jockey pulley 4 all is positioned at greater than main wheel and jockey pulley, 623 size.This structure can prevent that well limited slip wheel comes off out from track.Certainly the position of main wheel and jockey pulley also can exchange.
In order to make track structure simple, and reach the effect of province's material, the baffle plate 612 of get on the right track groove 621 and lower railway in getting on the right track is integrated.
Operating principle of the present utility model is: 2 jockey pulleys 4 by top contact the groove 621 that gets on the right track, and following main wheel 3 contacts the stressed together rotation of 611, four wheels of lower railway groove simultaneously, reaches the simultaneously function of forced-slip of four-wheel.
