Abstract

The utility model discloses a pulley part applied to a frameless window, comprising a wheel axle which is sheathed with a roller wheel; the roller wheel is limited between an upper and a lower convex rings which are respectively arranged at the upper and the lower end parts of the wheel axle; and a spring is sheathed between the top surface of the lower convex ring and the bottom surface of the roller wheel on the wheel axle. The pulley part is reasonable in structure and convenient for use, is beneficial to leading the roller wheel to run on a guide rail smoothly, has low noise, and can be widely applied to the frameless window.

Description

Be applied to not have the pulley spare on the frame window

Technical field

The utility model relates to a kind of pulley spare, particularly a kind of pulley spare that is applied to not have on the frame window.

Background technology

At present, the common pulley spare that is applied to not have on the frame window comprises wheel shaft, at the wheel outer shaft sleeve roller is housed, and this roller upper and lower surface is to be limited between the bulge loop of wheel shaft upper/lower terminal, when roller moves on guide rail, if run into the guide rail out-of-flatness, roller then moves not steady, causes the sash vibrations bigger, produce bigger noise, use inconvenience,, be necessary to make improvements at above-mentioned shortcoming.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provide a kind of rational in infrastructure, help roller and do not have pulley spare on the frame window in little being applied to of smooth and easy operation and noise on the guide rail.

The technical scheme that its technical problem that solves the utility model adopts is:

Be applied to not have the pulley spare on the frame window, comprise wheel shaft, be set with roller on the described wheel shaft, be provided with upper and lower bulge loop respectively in wheel shaft upper and lower end portion roller is limited between them, between lower convex ring end face and roller bottom surface, be with spring on the described wheel shaft.

The beneficial effects of the utility model are: when roller moves on guide rail when running into the guide pass out-of-flatness, but the spring pair roller between bulge loop end face and roller bottom surface plays cushioning effect, reduce the vibrations of roller, it is smooth and easy to make roller roll, also reduced simultaneously the noise that is brought when rolling, it is more convenient to allow the user use.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the utility model is installed to the structural representation on the no frame window.

The specific embodiment

With reference to Fig. 1, Fig. 2, be applied to not have the pulley spare on the frame window, comprise wheel shaft 1, be set with roller 2 on the described wheel shaft 1, be provided with upper and lower bulge loop 3,4 respectively in wheel shaft 1 upper and lower end portion roller 2 is limited between them, between lower convex ring 4 end faces and roller 2 bottom surfaces, be with spring 5 on the described wheel shaft 1.

When roller 2 moves on guide rail 10 when running into the guide pass out-of-flatness, but spring 5 pair rollers between lower convex ring 4 end faces and roller 2 bottom surfaces play cushioning effect, reduce the vibrations of roller 2, it is smooth and easy to make roller 2 roll, also reduced simultaneously the noise that is brought when rolling, it is more convenient to allow the user use.

The utility model is rational in infrastructure, easy to use, and it is little to help roller smooth and easy operation and noise on guide rail, is a kind of pulley spare that is widely used in not having on the frame window.

Claims

1. be applied to not have the pulley spare on the frame window, it is characterized in that: comprise wheel shaft (1), be set with roller (2) on the described wheel shaft (1), be positioned at wheel shaft (1) upper and lower end portion and be provided with upper and lower bulge loop (3,4) respectively roller (2) is limited between them, be positioned on the described wheel shaft (1) between lower convex ring (4) end face and roller (2) bottom surface and be with spring (5).
