In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0019] like Figure 1 and Figure 2 As shown, an adjustable pulley assembly of lifting and pushing hardware for doors includes a pulley mounting seat 3, a connecting seat 2 arranged on the pulley mounting seat 3, a first pulley 1 and a second pulley 4 arranged on the pulley mounting seat 3, two long first adjustment holes 6 are symmetrically arranged on the pulley mounting seat 3, both ends of the second pulley 4 are arranged in the first adjustment holes 6, and an adjustment mechanism 5 is also provided at one end of the pulley mounting seat 3. The position of the second pulley 4 relative to the first adjustment hole 6 is controlled by the adjustment mechanism 5, and the height position of the second pulley 4 can be adjusted by the adjustment mechanism 5.

[0020] When the second pulley 4 is in a different position in the first adjusting hole 6, the height of the second pulley 4 on the pulley mounting seat 3 is different, thereby realizing the height adjustment of the second pulley 4. The pulley mounting seat 3 is provided with an adjusting mechanism 5 for adjusting the height of the second pulley 4. During adjustment, the position of the second pulley 4 in the first adjusting hole 6 can be adjusted by the adjusting mechanism 5, thereby realizing the height adjustment of the second pulley 4 relative to the pulley mounting seat 3, thereby solving the problem of excessive weight or unevenness in the pushing and pulling process caused by uneven ground during installation, so that the pulley assembly can achieve the effect of uniform force when the ground is uneven after adjusting the height of the pulley, thereby making the movement of the door and window more flexible, simple in structure, convenient in installation, low in production cost and durable in use.

[0021] Further improved, the adjustment mechanism 5 includes an adjustment seat 52 connected to one end of the pulley mounting seat 3, second adjustment holes 55 symmetrically arranged on both sides of the adjustment seat 52, and an adjustment screw 54 arranged at the end of the adjustment seat 52, the two sides of the adjustment seat 52 are connected to the rotating shaft of the second pulley 4 through the second adjustment holes 55, and the distance between the adjustment seat 52 and the pulley mounting seat 3 is adjusted by the adjustment screw 54.

[0022] When the second pulley 4 is adjusted by the adjusting mechanism 5, the adjusting seat 52 is installed on both sides of the rotating shaft of the second pulley 4 through the second adjusting holes 55 on both sides, and the adjusting seat 52 and the pulley mounting seat 3 are connected through the rotating shaft, and an adjusting screw 54 is also installed at the end of the adjusting seat 52. Through the rotation of the adjusting screw 54, the adjusting seat 52 can be driven to move forward and backward relative to one end of the pulley mounting seat 3, so that the rotating shaft of the second pulley 4 is driven to slide along the first adjusting hole 6 through the adjusting seat 52, and finally the height adjustment of the second pulley 4 is achieved. When adjusting the height, the structure is simple and the operation is easy. Adjustment can be achieved without disassembling doors and windows, and the installation of the entire pulley assembly is also more convenient. Through the card position and the initial positioning of the product, the product can be directly installed by installing screws, and the product is easy to install.

[0023] As a further improvement, the second adjustment hole 55 is a long strip waist hole structure, and the second adjustment hole 55 and the first adjustment hole 6 are cross-arranged.

[0024] The second adjustment hole 55 and the first adjustment hole 6 are both long strip waist hole structures and are arranged crosswise, so that the height adjustment of the second pulley 4 can be realized while ensuring the horizontal movement of the adjustment seat 52, and the second pulley 4 can be stably moved when adjusted to any position state.

[0025] As a further improvement, the pulley mounting seat 3 includes two symmetrically arranged panels 31 and a fixed spacer 32 arranged between the two panels 31 , and the connecting seat 2 , the first pulley 1 and the second pulley 4 are all arranged between the two panels 31 .

[0026] The pulley mounting seat 3 has two sheet-like panels 31 assembled through a fixed spacer 32. The overall structure is simple and the manufacturing cost is low. The first pulley 1 and the second pulley 4 are respectively installed at the two ends of the pulley mounting seat 3, and the connecting seat 2 is installed between the first pulley 1 and the second pulley 4.

[0027] As a further improvement, a threaded adjustment hole 33 is provided on the fixed spacer 32 at one end of the pulley mounting seat 3 , and one end of the adjustment screw 54 is threadedly connected in the threaded adjustment hole 33 .

[0028] The pulley mounting seat 3 and the adjusting seat 52 can be positioned relative to each other by adjusting the screw 54, thereby avoiding the problem of relative flipping after installation. In addition, it is more convenient and simple to adjust the distance between the pulley mounting seat 3 and the adjusting seat 52 by adjusting the screw 54.

[0029] A further improvement is that the adjustment seat 52 is a U-shaped structure, a through hole 51 is provided at the bottom of the adjustment seat 52, a baffle 53 is provided at the end of the adjustment seat 52, a limiting hole 7 is provided on the baffle 53, and one end of the adjustment screw 54 passes through the limiting hole 7 and is connected to the threaded adjustment hole 33.

[0030] The adjusting seat 52 is a U-shaped structure and is sleeved on the outer side of one end of the pulley mounting seat 3, which can avoid the problem of shaking between the adjusting seat 52 and the pulley mounting seat 3, making its installation stability better. At the same time, due to the low height of the adjusting seat 52, the upper end of the second pulley 4 can be prevented from being pressed by the adjusting seat 52 through the through hole 51, thereby ensuring the installation space of the second pulley 4, and the baffle 53 with the limiting hole 7 at the end can make the adjusting screw 54 connected to the fixed spacer 32 after passing through the limiting hole 7, and in the process of adjustment, the relative position adjustment accuracy between the pulley mounting seat 3 and the adjusting seat 52 is higher, and the adjustment is more convenient.

[0031] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present application shall fall within the scope of protection required by the present application.
