[0024] Specifically, the axis of first connecting hole 111 can refer to the 0-0 dashed line in Figure 2 , the horizontal direction can refer to the A-A direction in Figure 2 , and the vertical direction can refer to the B-B direction in Figure 2 .

[0025] The hanging pulley provided by the embodiment has the following advantages. On the one hand, the pulley seat 1 ingeniously integrates the damper 4 and the roller 2, which not only saves space but also maintains the compactness of the structure, helps to maximize the use of the limited connection space on the upper side of the door panel 5, realizes efficient space layout, and on the other hand, more importantly, due to the inclination of the first connecting hole 111, when the door panel 5 exerts a downward pressure on the pulley seat 1 relative to the upper track 6, the pulley seat 1 can exert a downward pressure component on the end of the damper 4 away from the pulley seat 1. This design effectively enhances the installation stability of the damper 4, effectively prevents the damper 4 from being raised during use even in the case of a small thickness of the door panel 5 and limited connection space, and ensures the stable operation of the door leaf, reduces noise and vibration, and improves the user experience. Therefore, the hanging pulley is suitable for various door leaves without horizontal frames, and is particularly suitable for the case of a small thickness of the door panel 5.

[0026] Moreover, by arranging the first connecting hole 111 at the first end portion 11 of the pulley seat 1, more operation space and flexibility are provided for the installer, so as to ensure that the hanging pulley can be accurately matched with the door panel 5 and the upper track 6. This design not only simplifies the installation process, but also improves the installation efficiency and accuracy.

[0027] Specifically, in the embodiment, the rotating shaft of the roller 2 is located between the first end portion 11 and the second end portion 12.

[0028] Specifically, in the embodiment, the door panel 5 is not provided with horizontal frames and vertical frames.

[0029] It should be noted that in some other embodiments, the first connecting hole 111 can also be arranged on the seat body of the pulley seat 1 between the first end portion 11 and the second end portion 12, which can be selected according to actual needs, and is not limited herein.

[0030] As shown in Figure 2 and Figure 3 Preferably, in the embodiment, the length extension direction of the pulley seat 1 is parallel to the horizontal direction. In this way, on the one hand, the length extension direction of the pulley seat 1 is parallel to the horizontal direction, which ensures that the roller 2 can maintain a stable horizontal posture when rolling along the upper track 6. This design reduces the problem of unstable operation caused by the inclination or shaking of the roller 2, thereby improving the stability and smoothness of the door leaf during opening and closing. On the other hand, the hanging pulley can be more conveniently matched with the door panel 5 and the upper track 6 during installation. This design improves the installation adaptability and flexibility of the hanging pulley, so that it can be applied to door leaves of different sizes and shapes, and meets the individual needs of different users.

[0031] As shown in Figure 2 and Figure 3As shown, preferably, in the present embodiment, the included angle between the axis of the first connecting hole 111 and the vertical direction is defined as a, and a satisfies: 2°≤a≤3°. By setting a in the range of 2° to 3°, on the one hand, the lifting pulley can be suitable for door leaves of different sizes, weights and shapes, and such design improves the versatility and flexibility of the lifting pulley, so that it can meet the individual needs of different users and be widely used in various guide assemblies. On the other hand, it also helps to enhance the connection stability between the damper 4 and the door panel 5, so that the damper 4 can better fit on the door panel 5 after installation, reducing the problem of loosening or falling due to loose connection. At the same time, the stable connection structure also helps to improve the overall structural strength of the lifting pulley, thereby prolonging its service life.

[0032] As shown in Figure 2 and Figure 3 Preferably, in the present embodiment, the second end portion 12 is provided with a first shaft hole 121 and a waist-shaped hole 122. The first shaft hole 121 is used for rotational connection with the damper 4, and the waist-shaped hole 122 is used for limiting connection with the damper 4 to limit the up-down swing amplitude of the second end portion 12. Specifically, the damper 4 is provided with a first rotating shaft 42 and a limiting shaft 43. The first shaft hole 121 is a circular hole with a diameter matching that of the first rotating shaft 42 of the damper 4, and the first shaft hole 121 is rotationally connected to the first rotating shaft 42. Such connection allows the second end portion 12 to rotate relative to the damper 4 to a certain extent. The waist-shaped hole 122 is an elongated hole with its length direction perpendicular to the axis direction of the first shaft hole 121, and the waist-shaped hole 122 is limitingly connected to the limiting shaft 43. In this way, by designing the waist-shaped hole 122 as an elongated hole, an adaptive up-down swing control mechanism is realized. When the length of the damper 4 changes, the second end portion 12 can adjust the swing to adapt to such change through the waist-shaped hole 122, thereby avoiding excessive pressure on the damper 4. Such adaptive mechanism not only improves the stability and durability of the system, but also reduces the risk of system failure due to changes in the length of the damper 4.

[0036] As Figure 2 and Figure 3 shown, preferably, in the present embodiment, the axis of the fastener 3 is arranged in the vertical direction. By arranging the fastener 3 in the vertical direction, the stability of the connection is further enhanced, and the fastener 3 arranged in the vertical direction can more effectively resist the vertical load, which is complementary to the inclined first connecting hole 111, and together ensures the stability and reliability of the connection.

[0037] It should be noted that in some other embodiments, the axis of the fastener 3 can also be parallel to the axis of the first connecting hole 111, which can be selected according to actual needs.

[0039] 1) The pulley seat 1 ingeniously integrates the damper 4 and the roller 2, which not only saves space but also maintains the compactness of the structure, which helps to maximize the use of the limited connection space on the upper side of the door panel 5 and realizes efficient space layout;

[0040] 2) due to the inclination of the first connecting hole 111, the pulley seat 1 can exert a downward pressure component on the end of the damper 4 away from the pulley seat 1, which effectively enhances the installation stability of the damper 4, and effectively prevents the damper 4 from being tilted during use even in the case of small thickness of the door panel 5 and limited connecting space;

[0041] 3) by arranging the first connecting hole 111 at the first end portion 11 of the pulley seat 1, more operation space and flexibility are provided for the installer, thereby ensuring that the hanging pulley can be accurately matched with the door panel 5 and the upper rail 6;
