[0025] The present application will be described in further detail below in conjunction with the drawings.

[0026] Please refer to Figures 1 to 4 , the present embodiment discloses a guide mechanism for a door leaf without a horizontal frame, which comprises a damper 1, a pulley seat 2 and a roller 3; the damper 1 is arranged in a horizontal direction, and the damper 1 is arranged on the upper side of a door panel 5; the pulley seat 2 has a first end 21 and a second end 22, the second end 22 is connected to the damper 1, the length extension direction of the pulley seat 2 is inclined to the horizontal direction, the first end 21 is located on the side away from the damper 1 of the second end 22, the height of the first end 21 is lower than the height of the second end 22, the pulley seat 2 is further provided with a first connecting hole 23, the first connecting hole 23 is used for connecting the upper side of the door panel 5, and the axis of the first connecting hole 23 is inclined to the vertical direction; the roller 3 is arranged on the pulley seat 2.

[0027] Specifically, in the present embodiment, the horizontal direction can refer to the A-A direction in Figure 1 , the vertical direction can refer to the B-B direction in Figure 1 , the length extension direction of the pulley seat 2 can refer to the e1 direction in Figure 1 , and the axis of the first connecting hole 23 can refer toFigure 1 O-O dashed line in FIG.

[0028] The guide mechanism disclosed in the embodiment, due to the oblique arrangement of the first connecting hole 23 of the pulley seat 2, when the door plate 5 moves on the upper rail through the pulley seat 2 and exerts a downward pressure on the pulley seat 2, the oblique arrangement enables the pulley seat 2 to exert a downward pressure component on the end of the damper 1 away from the pulley seat 2, which effectively increases the stability of the damper 1 after installation, and effectively prevents the damper 1 from being warped during use even in the case of a small thickness of the door plate 5 and limited connection space.

[0029] Specifically, in the embodiment, no horizontal and vertical frames are arranged on the door plate 5.

[0030] As shown in Figure 1 , Figure 2 and Figure 3 , preferably, in the embodiment, the axis of the first connecting hole 23 is perpendicular to the length extension direction of the pulley seat 2, thus realizing the standardization of the production of the pulley seat 2, which not only simplifies the manufacturing process of the pulley seat 2, but also enables the selection of conventional pulley seat 2 specifications on the market, thereby reducing production costs and improving production efficiency, at the same time, the standardized pulley seat 2 is easier to install and maintain, reduces errors that may occur during installation, and further improves the stability and reliability of the entire guide mechanism.

[0031] As shown in Figure 1 , Figure 2 and Figure 3 , preferably, in the embodiment, two rollers 3 are arranged, and the two rollers 3 are arranged on both sides of the first connecting hole 23, on the one hand, the design of the two rollers 3 helps to disperse the pressure of the door plate 5 on the rail, reduces the excessive load borne by a single roller 3, thereby prolonging the service life of the roller 3, in addition, this layout can effectively reduce the vibration and noise generated by the door plate 5 during movement, improving the user's experience; on the other hand, since the two rollers 3 are respectively located on both sides of the first connecting hole 23, and the length extension direction of the pulley seat 2 is inclined downward relative to the damper 1, when the door leaf moves on the door rail through the rollers 3, the contact force of the rollers 3 on the rail will be converted into a downward component force, which is transmitted to the damper 1 through the pulley seat 2, which ensures that the damper 1 can continuously and stably receive downward pressure after installation, effectively preventing the damper 1 from being warped during use even in the case of a small thickness of the door leaf and limited connection space.

[0032] As shown in Figure 3 and Figure 4As shown, preferably, in the present embodiment, the second end portion 22 is provided with a first hinge hole 24 and a waist-shaped hole 25, the damper 1 is provided with a hinge shaft 11 and a limiting column 12, the first hinge hole 24 is rotationally connected with the hinge shaft 11, and the waist-shaped hole 25 is limitingly connected with the limiting column 12 to limit the up-and-down swing amplitude of the second end portion 22. In this way, the second end portion 22 is ingeniously designed with the first hinge hole 24 and the waist-shaped hole 25, which are matched with the hinge shaft 11 and the limiting column 12 on the damper 1. The first hinge hole 24 and the hinge shaft 11 achieve smooth rotational connection, while the waist-shaped hole 25 and the limiting column 12 form a stable limiting connection, which effectively controls the up-and-down swing amplitude of the second end portion 22. More importantly, the waist-shaped hole 25 adopts a long strip shape, which constitutes an adaptive swing adjustment mechanism. When the length of the damper 1 changes due to various factors, the second end portion 22 can make fine adjustments in swing through the waist-shaped hole 25, flexibly adapt to such changes, thereby avoiding excessive pressure on the damper 1. This adaptive mechanism not only significantly enhances the stability and durability of the system, but also greatly reduces the risk of system failure caused by changes in the length of the damper 1.

[0033] Preferably, in the present embodiment, the shell of the damper 1 is provided with a limiting seat 13 having an arc-shaped guide surface, and the second end portion 22 and the arc-shaped guide surface are in sliding contact. The limiting seat 13 is a part of the shell and protrudes, and its shape is carefully designed to be arc-shaped to cooperate with the second end portion 22 of the pulley seat 2. The curvature and size of the limiting seat 13 are strictly calculated and optimized to ensure that the arc-shaped guide surface and the sliding contact surface of the second end portion 22 of the pulley seat 2 can be closely and uniformly fitted, thereby providing stable and reliable support and guiding functions. When the second end portion 22 of the pulley seat 2 is in contact with the arc-shaped guide surface and moves relatively, the sliding friction between them becomes the main mode of motion, and the guiding effect of the arc-shaped guide surface enables the second end portion 22 to strictly follow the predetermined path when swinging up and down, effectively avoiding system instability or damage problems that may be caused by swing path deviation. This sliding contact and guiding mechanism not only significantly improves the stability and durability of the system, but also further reduces the noise generated during system operation by reducing unnecessary friction and wear.

[0034] As Figure 1 and Figure 3As shown, preferably, in the embodiment, the included angle between the axis of the first connecting hole 23 and the vertical direction is defined as a, and a satisfies: 2°≤a≤5°. In this way, by precisely controlling the size of the included angle a, the stability of the entire guide mechanism is effectively enhanced, and this design enables the pulley seat 2 to better disperse stress when bearing the weight and moving force of the door plate 5, thereby avoiding damage or failure caused by stress concentration; and the reasonable setting of the included angle a also significantly improves the durability of the guide mechanism, since unnecessary friction and wear are reduced, the service life of the pulley seat 2 is effectively prolonged, thereby reducing the maintenance cost.

[0035] Preferably, in the embodiment, the guide mechanism further comprises a fastener 26, a worm wheel 27 and a worm 28, the first connecting hole 23 is arranged on the worm wheel 27, the worm wheel 27 is rotationally arranged on the pulley seat 2, the worm 28 is in meshing connection with the worm wheel 27, and the fastener 26 is threadedly connected to the first connecting hole 23 and used to be connected to the upper side of the door plate 5. In this way, by rotating the worm 28, the worm wheel 27 in meshing connection with the worm 28 can be driven to rotate around its own axis, and since the first connecting hole 23 is arranged on the worm wheel 27 and the fastener 26 is threadedly connected to the first connecting hole 23, the rotation of the worm wheel 27 will drive the fastener 26 to move up and down. This design enables the guide mechanism to easily adapt to door plates 5 of different heights without the need for additional adjustment tools or steps, thereby greatly improving the convenience of installation and use.

[0036] In addition, as shown, Figure 5 The embodiment also provides a door and window system, which comprises the guide mechanism described above and further comprises a door plate 5, the damper 1 is arranged on the upper side of the door plate 5, and the first connecting hole 23 is connected to the upper side of the door plate 5. The door and window system has all the advantages of the guide mechanism described above, and details are not repeated here.

[0037] In summary, the guide mechanism and the door and window system comprising the guide mechanism disclosed in the utility model can at least bring the following beneficial technical effects:

[0038] 1) The pulley seat 2 ingeniously integrates the damper 1 and the roller 3, which not only saves space but also maintains the compactness of the structure, is helpful to maximize the use of the limited connection space on the upper side of the door plate 5, and realizes efficient space layout;

[0039] 2) Since the first connecting hole 23 of the pulley seat 2 is arranged obliquely, when the door plate 5 moves on the upper rail through the pulley seat 2 and exerts a downward pressure on the pulley seat 2, the pulley seat 2 can exert a downward pressure component on the end of the damper 1 away from the pulley seat 2, which can effectively prevent the damper 1 from being warped during use;

[0040] 3) The standardization of the pulley seat 2 production is realized, the conventional pulley seat 2 specifications in the market can be selected, thereby the production cost is reduced and the production efficiency is improved, meanwhile, the standardized pulley seat 2 is easier to install and maintain, the errors possibly appearing in the installation process are reduced;

[0041] 4) The rotation of the worm wheel 27 drives the fastener 26 to move up and down, this design makes the guide mechanism easily adapt to the door plate 5 of different heights, without additional adjustment tools or steps, greatly improving the convenience of installation and use.
