Technical Field
[0001] The present application relates to the technical field of folding doors and windows, and in particular to a high-stability pulley assembly for folding doors and windows. Background Art
[0002] Folding doors and windows have the advantages of saving space, being easy to retract and open, and being bright and transparent. They are widely used in office buildings and residences. When the folding doors and windows move in the door and window frames, they need to rely on the pulley assembly to support them. At the same time, the pulley assembly moves on the slide rail of the door and window frame, which can effectively save the force applied when the folding doors and windows are pushed and pulled. However, the contact area between the pulley assembly and the slide rail is small, and it is extremely unstable during the sliding process. If the force is uneven, it is very easy to deviate from the slide rail or even fall off and get stuck in the door and window frame, which makes the folding doors and windows unable to move inside the door and window frame. Utility Model Content
[0003] In order to solve the problem that the pulley assembly proposed above may easily deviate from the slide rail or even fall off and get stuck in the door and window frame if the force is unevenly applied during the sliding process, thus making the folding door and window unable to move inside the door and window frame, the present application provides a high-stability pulley assembly for folding doors and windows.
[0004] The high stability pulley assembly for folding doors and windows provided in this application adopts the following technical solution:
[0005] The top end of the support leg is fixedly provided with a fixing block, and the top end of the fixing block is locked with the fixing block, and the fixing block is locked with the fixing block at two ends.
[0006] Preferably, the pulley member is composed of a fixed shaft and a pulley block, the pulley block is located inside the support block, the fixed shaft is fixedly passed through the support block, and the pulley block is movably sleeved on the outer surface of the fixed shaft.
[0007] Preferably, the mounting member is composed of a mounting block and two hexagon socket head cap screws. The mounting block is fixedly connected to the top of the support block, and the two hexagon socket head cap screws respectively penetrate through both ends of the bottom of the mounting block in a threaded manner.
[0008] Preferably, the limiting member is composed of a limiting shaft and a limiting block. The limiting shaft is fixedly connected to one side of the fixed block. The middle part of the movable rod is movably sleeved on the outer surface of the limiting shaft. The limiting block is fixedly connected to one end of the limiting shaft, and one side of the limiting shaft is in contact with one side of the movable rod.
[0009] In summary, the present application includes the following beneficial technical effects: By拨动 the screw to drive the movable rod to rotate counterclockwise around the limiting shaft, the movable rod drives the sliding shaft to slide inside the sliding hole, and at the same time抵触 the U-shaped block to descend, ensuring that both ends of the bottom of the U-shaped block are lower than the height of the support block and are respectively located on both sides of the sliding rail inside the door and window frame. Then rotate the screw so that one end of the screw is movably inserted into another jack, thereby fixing the movable rod and indirectly fixing the U-shaped block. The fixed U-shaped block can then limit the pulley member, preventing the pulley member from shifting and falling off the sliding rail when sliding on the sliding rail inside the door and window frame, thereby effectively improving the stability of the pulley member when sliding on the sliding rail.

[0014] The following is a further detailed description of the present application in conjunction with the attached Figure 1-3 to further illustrate the present application.
[0015] The embodiment of the present application discloses a high-stability pulley assembly for folding doors and windows. Refer to Figure 1-3 It should be noted that the text contains some unclear or incorrect expressions in Chinese (such as "抵触"), which may affect the accuracy of the translation. It is recommended to check and correct the original text for a more accurate translation., including a support block 1, a U-shaped block 41 and a movable rod 46. An installation member 3 is provided at the top of the support block 1. The installation member 3 consists of an installation block 31 and two hexagon socket head cap screws 32. The installation block 31 is fixedly connected to the top of the support block 1. The two hexagon socket head cap screws 32 respectively thread through both ends of the bottom of the installation block 31, and both of the two hexagon socket head cap screws 32 are threadedly connected to the folding door and window, so that the support block 1 can be fixedly installed at the corner of the folding door and window. Two pulley members 2 are movably arranged inside the support block 1. The pulley member 2 consists of a fixed shaft 21 and a pulley block 22. The pulley block 22 is located inside the support block 1. The fixed shaft 21 fixedly penetrates the support block 1. The pulley block 22 is movably sleeved on the outer surface of the fixed shaft 21. The fixed shaft 21 can support the pulley block 22. When the two pulley blocks 22 slide on the slide rail inside the door and window frame, they can drive the support block 1 and the folding door and window to move. The U-shaped block 41 is located on one side of the support block 1. Two concave blocks 42 are fixedly connected to the edge of one side of the support block 1. Both ends of the bottom of the U-shaped block 41 respectively penetrate through the two concave blocks 42 movably. The cooperation of the two concave blocks 42 can limit the U-shaped block 41, so that the U-shaped block 41 is in a vertical state on one side of the support block 1, and at the same time, one side of the U-shaped block 41 is attached to one side of the support block 1. A fixed block 43 is fixedly connected to the top of one side of the support block 1. The top of the U-shaped block 41 abuts against the bottom end of the fixed block 43. A limiting member 5 for supporting the movable rod 46 is arranged on one side of the fixed block 43. The limiting member 5 consists of a limiting shaft 51 and a limiting block 52. The limiting shaft 51 is fixedly connected to one side of the fixed block 43. The middle part of the movable rod 46 is movably sleeved on the outer surface of the limiting shaft 51. The limiting block 52 is fixedly connected to one end of the limiting shaft 51. One side of the limiting block 52 is attached to one side of the movable rod 46, which can limit the movable rod 46, so that the movable rod 46 can only rotate around the limiting shaft 51 as the axis, and at the same time, one side of the movable rod 46 is attached to one side of the fixed block 43. A sliding hole is opened on one side of the U-shaped block 41. A sliding shaft 44 slides inside the sliding hole. One end of the sliding shaft 44 is fixedly connected to one side of the movable rod 46. One end of the movable rod 46 is threadedly penetrated with a screw 45. Two jacks are opened at both corners on one side of the support block 1. One end of the screw 45 is movably inserted into the inside of one of the jacks. After buckling the pulley block 22 on the slide rail inside the door and window frame, rotate the screw 45 so that one end of the screw 45 disengages from the inside of one of the jacks, thereby releasing the fixation of the U-shaped block 41. Then,拨动 the screw 45 to drive the movable rod 46 to rotate counterclockwise around the limiting shaft 51. At this time, the sliding shaft 44 on the movable rod 46 slides inside the sliding hole, and at the same time, it abuts against the U-shaped block 41 to descend, so that both ends of the bottom of the U-shaped block 41 are lower than the height of the support block 1, and then are located on both sides of the slide rail inside the door and window frame. Then, rotate the screw 45 so that one end of the screw 45 is movably inserted into another jack, thereby fixing the movable rod 46 and indirectly fixing the sliding shaft 44.Prevent the sliding shaft 44 from sliding inside the sliding hole and touching the U-shaped block 41 for lifting. After the U-shaped block 41 is fixed, it can limit the pulley block 22 to prevent the pulley block 22 from falling off the sliding rail when sliding on the sliding rail.
[0016] The implementation principle of a highly stable pulley assembly for folding doors and windows in an embodiment of this application is as follows: During use, the support block 1 is fixedly installed at the corner of the folding doors and windows by using the mounting member 3. Then, the folding doors and windows are installed in the window frame and it is ensured that both pulley members 2 are slidably connected to the sliding rails of the window frame. Then, the screw 45 is rotated so that one end of the screw 45 disengages from the inside of one of the jacks, thereby releasing the fixation of the U-shaped block 41. At this time, the screw 45 is拨动 to drive the movable rod 46 to rotate counterclockwise around the limiting shaft 51. At this time, the sliding shaft 44 on the movable rod 46 slides inside the sliding hole and simultaneously touches the U-shaped block 41 to descend, ensuring that both ends of the bottom of the U-shaped block 41 are lower than the height of the support block 1, so that both ends of the bottom of the U-shaped block 41 are located on both sides of the sliding rail inside the window frame. Then, the screw 45 is rotated so that one end of the screw 45 is movably inserted into another jack, thereby fixing the movable rod 46 and indirectly fixing the U-shaped block 41. After the U-shaped block 41 is fixed, it can limit the pulley block 22 to prevent the pulley block 22 from shifting and falling off the sliding rail when sliding on the sliding rail.
