The utility model content
The purpose of this utility model is exactly to adopt spiral regulating device to regulate the defective of height in order to overcome existing door and window trolley, and a kind of door and window adjustable pulley is provided.
The technical scheme that its technical problem that solves the utility model adopts is:
The door and window adjustable pulley, comprise roller, it is characterized in that: also comprise the outside framework that matches with the door and window framework, outside framework has the die cavity that runs through up and down, be provided with turning rolls in the bottom die cavity of outside framework, the side of turning rolls is provided with slide block, is provided with chute on the outside framework of slide block correspondence, is provided with described roller on turning rolls; Be provided with cam in the top die cavity of outside framework, a side of cam is provided with connecting hole, and the extrados of cam is pressed on the upper surface of turning rolls.
On the basis of above-mentioned main technical schemes, can increase following further perfect technical scheme:
The angle of the upper surface of described turning rolls and cam extrados is 0～40 ° a angle of repose.
The die cavity of described outside framework be the rectangle die cavity.
Described cam both sides are provided with camshaft, are provided with axis hole on the both sides of the outside framework of camshaft correspondence.
Be provided with connecting hole on the camshaft of cam one side, connecting hole can cooperate with some instruments, and rotating cam pair roller frame carries out height to be regulated.
The outside at the outside framework of cam opposite side correspondence is provided with pad, can adopt during greater than outside framework when the space of door and window framework pad is installed on outside framework, and outside framework and door and window framework are connected.
The upper end of described turning rolls is a platform, and the extrados of cam is pressed on the upper end platform of turning rolls.
The beneficial effects of the utility model provide a kind of height that utilizes the different wheel diameters adjusting roller of cam, the weight of the arrangement for adjusting height carrying of pulley has been improved, simplify the adjustment structure of pulley, and made regulative mode convenient, helped user's use.
Below in conjunction with drawings and Examples the utility model is further specified.
Description of drawings:
Fig. 1 is a first direction stereogram of the present utility model;
Fig. 2 is a second direction stereogram of the present utility model;
Fig. 3 is a part drawing of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model door and window adjustable pulley, comprise the outside framework 4 that matches with the door and window framework, outside framework 4 has the die cavity 42 that runs through up and down, die cavity be the rectangle die cavity, be provided with turning rolls 6 in the bottom die cavity of outside framework 4, turning rolls 6 is the turning rolls of rectangular structure, the bottom of turning rolls 6 is provided with the opening cavity that is used to place roller, turning rolls 6 upper ends are a platform, being respectively equipped with an arched door on turning rolls 6 two sides communicates with opening cavity, the both sides of each arched door are respectively equipped with a symmetrical slide block 61, described slide block is the convex dot shape slide block, on the outside framework 4 of slide block correspondence, be provided with chute 41, described turning rolls 6 is connected by the chute 41 on its top shoe and the outside framework 4, on turning rolls 6, be provided with roller 5, roller 5 both sides are provided with roller shaft, on the both sides of the turning rolls 6 of roller shaft correspondence, be provided with axis hole, on the outside framework 4 of the arched door correspondence of turning rolls 6, be provided with corresponding arched door, these two arched doors can be avoided when roller is big, can't be installed on the turning rolls, be provided with cam 7 in the top die cavity of outside framework, the extrados of cam 7 is pressed on the upper end platform of turning rolls 6, the upper end flat upper surface of described turning rolls 6 and the angle of cam extrados are the angle of repose less than 30 °, described angle of repose is along with the variation of cam extrados, angle of repose changes in 30 °, can guarantee like this that cam is pressed on the upper end flat upper surface of turning rolls 6 remains stable status, according to the cam material difference, can change the extrados of cam, the angle of repose of the upper end flat upper surface of the extrados of cam and turning rolls 6 is increased accordingly or reduce, cam is pressed on the upper end flat upper surface of turning rolls 6 remains stable status, cam 7 both sides are provided with camshaft 71, on the both sides of the outside framework of camshaft correspondence, be provided with axis hole, cam 7 is connected by camshaft on it 71 and outside framework, the camshaft of one side of cam is provided with connecting hole, the outside at the outside framework 4 of cam opposite side correspondence is provided with pad 2, pad 2 is provided with two buckles, be provided with draw-in groove on the outside framework of buckle correspondence, pad is connected by buckle on it and outside framework.
