The specific embodiment is as follows:
embodiment 1, as shown in fig. 1 and 2, a pulley for an al-alloy door & window includes a bracket and a roller device 4. The roller device 4 includes a wheel seat in a U shape as a whole and a roller connected in the wheel seat.
The support comprises a support frame 1, a first adjusting arm 2, a sliding part, a second adjusting arm 10 and a driving part. The support frame 1 is rectangular and is provided with a downward opening. The support frame 1 is used for being connected to the bottom of a door window. The left end at top is provided with cushion 3 in the carriage 1, and it has first regulating arm 2 to articulate on the cushion 3, and first regulating arm 2 can the horizontal hunting around the pin joint. The other end of the first adjusting arm 2 is connected with the left end of the top of the wheel seat. The top of the support frame 1 is further provided with a sliding chute extending along the left-right direction, and the sliding chute comprises a first sliding chute 12 and a second sliding chute 11. The first sliding groove 12 and the second sliding groove 11 are both in a concave shape and are symmetrically arranged. The first sliding chute 12 is fixed on the front side wall of the support frame 1, and the second sliding chute 13 is fixed on the rear side wall of the support frame 1. The sliding part is connected with the sliding chute and comprises a sliding plate 8, a first sliding block 9 and a second sliding block 13. The first slider 9 and the second slider 13 are connected to the upper ends of the front and rear sides of the slide plate 8, respectively. The first sliding block 9 extends into the first sliding groove 12, and the second sliding block 13 extends into the second sliding groove 11, so that the sliding part is connected with the sliding grooves. A second adjusting arm 10 is hinged to the left side of the sliding plate 8, and the other end of the second adjusting arm 10 is hinged to the right end of the top of the wheel seat; therefore, the first adjusting arm 2, the wheel seat, the second adjusting arm 10 and the supporting frame 1 are connected end to form an isosceles trapezoid.
Note that the thickness of the spacer 3 is the same as the thickness of the chute.
The driving piece is arranged at the right side of the sliding plate 8 and used for driving the sliding plate 8 to slide left and right along the sliding chute. The sliding plate 8 drives the second adjusting arm 10 to slide in the process of sliding left and right, and then the height of an isosceles trapezoid formed by the first adjusting arm 2, the wheel seat, the second adjusting arm 10 and the supporting frame 1 is adjusted, so that the height of the pulley is adjusted.
This embodiment an aluminum alloy door and window's pulley is when using, connects carriage 1 in door and window's bottom to drive door and window through roller device 4 and remove, save the physical power of push-and-pull door bed. When necessary, the position of the sliding plate 8 in the sliding groove is adjusted through the driving piece, the height of an isosceles trapezoid formed by the first adjusting arm 2, the wheel seat, the second adjusting arm 10 and the supporting frame 1 is adjusted, the pulley is conveniently adjusted to a proper height, the door and window can be conveniently installed, friction between the bottom of the door and window and a track can be avoided, and the practicability is high; the height can be adjusted by adjusting the position of the sliding plate 8 through the driving piece, the adjusting structure is simple, the operation is simple and convenient, and the use by people is convenient.
