Abstract
The utility model discloses a pulley of a door window, which comprises a plastic wheel, a metal ring and a wheel shaft, wherein the center of the plastic wheel is provided with a groove; the metal ring is inlaid in the groove and connected with the wheel shaft by a rolling body in a rolling connection mode; the plastic wheel having the action of damping and friction removal is difficult to fall off from the whole wheel body; the wheel shaft is connected with the wheel body in a rolling connection mode, thereby, the slide friction resistance of the wheel shaft and the wheel body is reduced, the abrasion and the noise are reduced, and the service life of the pulley is prolonged, and furthermore, one end of the wheel shaft is connected with a concentric stop dog, the other end surface of the concentric stop dog is connected with an eccentric screw rod and the installation height of a door body or a window body can be adjusted by adjusting the eccentric screw rod. All in all, the utility model has the advantages of convenient use and long service life and the installation height of the door body or the window body can be conveniently adjusted.
Description
Technical field
The utility model relates to a kind of pulley, particularly a kind of pulley that is installed on the sliding door, window.
Background technology
Existing door and window trolley mainly is made up of wheel shaft and metal wheel body, when the metal wheel body slides on the metal guide rail of doorframe or window frame, is easy to generate wearing and tearing and noise each other; In order to address the above problem, people put neither too hard, nor too soft plastic layer in that metal wheel is external.Yet the plastic layer that directly is enclosed within on the metal wheel body comes off in sliding process easily, and the plastic layer that comes off can stop up the slideway on the guide rail, and a body can not be moved, and makes troubles to use; In addition, because wheel shaft is similarly the hardmetal material, there are bigger mill sassafras resistance in itself and metal wheel body in rolling process, and wearing and tearing and noise can produce between the two at them equally; If wearing and tearing are relatively more severe, will influence the stationarity of rail, the application life of having reduced pulley.
Summary of the invention
In order to overcome the above prior art deficiency, the utility model provides a kind of easy to use, door and window trolley that the life-span is long.
The another one purpose is to provide a kind of pulley that can make things convenient for the setting height(from bottom) of adjustment doors body or forms.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of door and window trolley is characterized in that comprising plastic roller, metal ring and wheel shaft, and the center of described plastic roller is provided with groove, is inlaid with metal ring in the groove, and metal ring rolls with wheel shaft by rolling element and is connected.
As preferred version of the present utility model be:
The shaft shoulder surface of the inner edge of described metal ring and wheel shaft is respectively equipped with concave ring groove, and described rolling element places between concave ring groove;
Described plastic roller groove floor is provided with central through hole, and wheel shaft passes central through hole;
One end of described wheel shaft is connected with concentric block, and the other end of block is connected with eccentric screw;
Described axial plane is provided with between the metal ring of teeth and the wheel shaft plastic cage is installed, and is filled with sliding agent in the plastic cage.
The beneficial effects of the utility model are: because metal ring is embedded in the groove of plastic roller, metal ring closely is connected with plastic roller, therefore, has the plastic roller that damping wears down effect and is difficult to drop out from whole wheel body; And wheel shaft and wheel body be connected for rolling, thereby significantly reduced the sliding friction resistance of wheel shaft and wheel body, reduced wearing and tearing and noise, prolonged the application life of pulley.In addition, because an end of wheel shaft is connected with concentric block, the other end of block is connected with eccentric screw with one heart, and the setting height(from bottom) of door body or forms can be adjusted by regulating eccentric screw; In a word, the utlity model has advantage easy to use, that the life-span is long, and can make things convenient for the setting height(from bottom) of adjustment doors body or forms.
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 A of Fig. 1 is to view.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of door and window trolley comprises plastic roller 1, metal ring 7 and wheel shaft 2, and the center of described plastic roller 1 is provided with groove, is inlaid with metal ring 7 in the groove, and metal ring 7 rolls with wheel shaft 2 by rolling element 4 and is connected.
In the present embodiment, the shaft shoulder surface of the inner edge of described metal ring 7 and wheel shaft 2 is respectively equipped with concave ring groove 7A and 2A, and described rolling element 4 places between concave ring groove 7A and the 2A.
The groove floor of described plastic roller 1 is provided with central through hole, wheel shaft 2 passes central through hole and is connected with concentric block 5, the other end of block 5 is connected with eccentric screw 6, and the setting height(from bottom) of door body or forms can be adjusted by regulating eccentric connecting screw rod 6, with the installation of this convenient door body or forms.
For metal ring 7 more closely is installed in the plastic roller 1, prevent that both from skidding mutually and come off, metal ring is distributed with positioning body teeth 7B on 7 surfaces, and there is the alveolus 1B that matches with positioning body teeth 7B the groove inboard of plastic roller 1.
In order farthest to reduce the friction of rolling element 4 and concave ring groove 7A, 2A, prolong the application life of pulley, the plastic cage 3 of separating rolling element 4 is installed between described metal ring 7 and the wheel shaft 2, be filled with sliding agent in the plastic cage 3.
Certainly, the groove floor of described plastic roller 1 can be enclosed planar, and wheel shaft 2 is connected by rolling element 4 metal ring 7 rollings direct and in the mosaic groove from the opening part of groove.
In a word, except that above-mentioned embodiment, with the technical scheme that the utility model is equal to also should be within the protection domain of the invention.
