Description

Technical Field

[0001] This utility model belongs to the technical field of hollow windows and doors, and specifically relates to a hollow glass window with built-in sunshade. Background Technology

[0002] Traditional insulated windows with built-in sunshades use pulley systems to drive the raising and lowering of the sunshade. Since traditional fixed pulleys often have a circular cross-section design, radial offset or slippage can easily occur when the ropes are wound around, exacerbating the instability of the raising and lowering process. In addition, due to certain installation errors during assembly, the pulley assembly of the sunshade may rub and impact with the inner wall of the mounting frame during the raising and lowering process due to installation gaps or transmission offsets, which can lead to component deformation, abnormal noise, and a shorter service life. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a double-glazed window with built-in sunshade. The technical problem to be solved by this utility model is: how to improve the service life of the fixed pulley assembly and the mounting frame.

[0004] The objective of this utility model can be achieved through the following technical solution: a hollow glass window with built-in sunshade, comprising an installation frame and a sunshade assembly. The installation frame includes a horizontal frame and a vertical frame. The sunshade assembly includes a sunshade curtain, a lifting control handle, and a lifting cord. One end of the sunshade curtain is located inside the horizontal frame, and the lifting control handle is located inside the vertical frame. The vertical frame is characterized by having a fixed pulley assembly fixed at its top. The fixed pulley assembly includes two main pulleys and a secondary pulley that can increase friction. One end of the lifting cord is connected to the lifting control handle, and the other end passes around the two fixed pulleys and is connected to the sunshade curtain. A locking part is protruding from one side of the fixed pulley assembly, and the fixed pulley assembly is fixed to the horizontal frame through the locking part.

[0005] This application utilizes an existing insulated glass unit with sunshade function. The unit moves up and down via a lifting control handle within the vertical frame. A fixed pulley system above the handle alters the direction of the lifting cable's force, thereby moving the sunshade curtain located on one side of the lifting control handle. This allows for the collection and unfolding of the sunshade curtain. To reduce impact caused by relative displacement between the fixed pulley system and the horizontal frame during lifting, this application features a locking part protruding from one side of the fixed pulley system that engages with the horizontal frame. This locking part secures the fixed pulley system to the horizontal frame, preventing impact and further reducing relative displacement between them, thus extending the service life of both the fixed pulley system and the horizontal frame.

[0006] In the aforementioned insulated glass window with built-in sunshade, the fixed pulley assembly also includes a housing that can connect to the horizontal frame. The snap-fit ​​part is protruding on the left side of the housing, making the housing L-shaped, and the snap-fit ​​part can be snapped into the horizontal frame.

[0007] In the aforementioned double-glazed window with built-in sunshade, the top of the latching part is provided with several anti-return plates that contact the inner wall of the horizontal frame. The anti-return plates are inclined towards the fixed pulley assembly, and a U-shaped groove that can cooperate with the horizontal frame is provided below the latching part. By providing anti-return plates on the latching part and tilting them at a certain angle, the stability of the latching part insertion is improved.

[0008] In the aforementioned double-glazed window with built-in sunshade, the main pulley and auxiliary pulley include a rope winding part and a ratchet part. The ratchet part is located on one side of the rope winding part. The housing contains two pawls that can engage with the ratchet part, with each pawl corresponding to a different ratchet part. By providing ratchet parts on the main pulley and auxiliary pulley, self-locking of the pulleys is achieved, preventing the sunshade from falling due to the lower counterweight after the lifting control handle stops moving, thus ensuring the sunshade can remain suspended.

[0009] In the aforementioned double-glazed window with built-in sunshade, the rope winding section has 3-6 surfaces that cooperate to form a polygonal cross-section. By using a polygonal rope winding section, the friction between the lifting rope and the winding section is increased, preventing slippage during use.

[0010] In the aforementioned double-glazed window with built-in sunshade, the rope winding section has 3-6 protruding ridges that contact the lifting rope. These ridges are evenly distributed circumferentially on the rope winding section. By providing 3-6 protruding ridges on the rope winding section that contact the lifting rope, the friction between the lifting rope and the rope winding section is increased, preventing slippage during use.

[0011] In the aforementioned double-glazed window with built-in sunshade, the main pulley and the auxiliary pulley are staggered vertically within the housing.

[0012] In the aforementioned hollow glass window with built-in sunshade, a rope passage is provided on the other side of the housing for the lifting rope to pass through. One end of the lifting rope is fixed to the lifting control handle, and the other end is inserted through the bottom of the fixed pulley group, passes around the auxiliary pulley located below, exits the fixed pulley group, passes around the movable pulley at the top of the lifting control handle, re-enters the fixed pulley group through the rope passage, and after contacting the main pulley, exits the fixed pulley group and connects with the sunshade curtain.

[0013] In the aforementioned double-glazed window with built-in sunshade, one end of the lifting rope is fixed to the lifting control handle, and the other end is connected to the bottom of the sunshade curtain via a fixed pulley group. When the lifting control handle moves up and down within the vertical frame, the lifting rope via the fixed pulley group drives the sunshade curtain to unfold or retract.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This application increases the friction between the main pulley and the auxiliary pulley and the lifting rope by setting the rope winding part of the main pulley and the auxiliary pulley in the shape of a polygon formed by 3-6 faces. At the same time, the fixed pulley group is fixed to the horizontal frame by the snap-fit ​​part, and the snap-fit ​​part on the housing is used to fix it to the horizontal frame, so as to avoid the impact caused by the relative displacement of the two during the lifting process, and improve the service life of the mounting frame and the fixed pulley group.

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figure 1 as well as Figure 2 As shown, a double-glazed window with built-in sunshade includes a mounting frame 1, a sunshade assembly 2, and glass 4. The mounting frame 1 includes vertical frames 1b on the left and right sides and a horizontal frame 1a. The sunshade assembly 2 includes a sunshade curtain 2a and a lifting control handle 2b. The sunshade curtain 2a and the lifting control handle 2b are connected by a lifting rope 2c. One end of the sunshade curtain 2a is located inside the horizontal frame 1a, and the lifting control handle 2b is located inside the vertical frame 1b. One end of the lifting rope 2c is fixed to the lifting control handle 2b and passes through a fixed pulley group 3 at the top of the vertical frame 1b. The lifting rope 2c, which is parallel to the vertical frame 1b, passes through the fixed pulley group 3 and is perpendicular to the vertical frame 1b, and is connected to the bottom of the sunshade curtain 2a.

[0023] It is worth mentioning that, such as Figure 1 and Figure 2 As shown, in this embodiment, Venetian blinds are used as sunshade curtains 2a, and a flipping component 2d that can control the flipping of Venetian blinds is provided on the vertical frame 1b and the horizontal frame 1a on the other side. The use of Venetian blinds as sunshade curtains 2a is only one embodiment of this application. Based on this, other curtains such as roller blinds and honeycomb blinds can also be used as sunshade curtains 2a. The curtain structures of roller blinds and honeycomb blinds are existing technologies and will not be described in detail here.

[0024] like Figure 2 and Figure 3 As shown, the fixed pulley group 3 includes a housing 3c and a main pulley 3a and an auxiliary pulley 3b located inside the housing 3c. The main pulley 3a and the auxiliary pulley 3b are staggered vertically. One end of the lifting rope 2c is fixed to the top of the lifting control handle 2b, and the other end passes around the auxiliary pulley 3b below the fixed pulley group 3, then around the movable pulley at the top of the lifting control handle 2b, and re-enters the fixed pulley group 3, rests on the main pulley 3a, and passes through the snap-fit ​​part 3c 1 to connect with the bottom beam at the bottom of the sunshade curtain 2a.

[0025] like Figure 3 and Figure 4 As shown, the fixed pulley assembly 3 is located at the corner of the mounting frame 1 and is connected to the vertical frame 1b and the horizontal frame 1a respectively. The fixed pulley assembly 3 includes an L-shaped housing 3c, a main pulley 3a, and an auxiliary pulley 3b. The main pulley 3a and the auxiliary pulley 3b are rotatably disposed within the housing 3c, and the main pulley 3a and the auxiliary pulley 3b are vertically offset. The auxiliary pulley 3b is located below the main pulley 3a. Both the auxiliary pulley 3b and the main pulley 3a are provided with a rope winding portion 3d, and the cross-section of the rope winding portion 3d is square. One side of the housing 3c protrudes a certain distance along the length of the horizontal frame 1a, forming a locking portion 3c 1. A check plate 3c 2 is provided above the locking portion 3c 1. A U-shaped groove 3c5 that can cooperate with the horizontal frame 1a is provided below 1. The check plate 3c2 is inclined in the opposite direction to the insertion of the fixed pulley group 3. More importantly, the use of a rope winding part 3d with a square cross section is only a specific embodiment of this application, and does not mean that the rope winding part 3d can only be square. In order to improve the friction between the rope winding part 3d and the lifting rope 2c, this application can also design the cross section of the rope winding part 3d to be any geometric shape formed by 3-6 faces.

[0026] It is worth mentioning that, such as Figure 4As shown, in addition to the rope winding part 3d, the main pulley 3a and the auxiliary pulley 3b are also provided with a ratchet part 3e located on one side of the rope winding part 3d. The ratchet part 3e is a toothed ratchet part 3e. The housing 3c is oscillatingly connected to a pawl 3c3, and the end of the pawl 3c3 is engaged with the ratchet part 3e.

[0027] In summary, existing insulated glass units with built-in sunshades 4 move up and down via a lifting control handle 2b located within the vertical frame 1b. A fixed pulley group 3 is installed at the top of the vertical frame 1b. By changing the direction of the force of the lifting rope 2c, the lifting rope 2c, which winds around the fixed pulley group 3, drives the sunshade 2a to complete the collection and unfolding action. This application, based on the existing insulated glass units with built-in sunshades 4, employs two vertically arranged and horizontally staggered main pulleys 3a and auxiliary pulleys 3b. By first winding the lifting rope 2c around the auxiliary pulley 3b, and then around the movable pulley at the top of the lifting control handle 2b, a labor-saving effect is achieved. The rope is then threaded through a... The guide 3d contacts the main pulley 3a, thereby changing the direction of the force of the lifting rope 2c. In addition, this application provides a pawl 3c3 in the housing 3c of the fixed pulley group 3, and the pawl 3c3 engages with the ratchet part 3e on one side of the main pulley 3a and the auxiliary pulley 3b through the ratchet 3c3, so as to avoid the possibility of the main pulley 3a and the auxiliary pulley 3b reversing when the lifting control handle 2b moves up and down. In addition, in order to prevent the lifting rope 2c from slipping during the movement, a polygonal rope winding part 3d is adopted. By winding the lifting rope 2c on the polygonal rope winding part 3d, the friction between the lifting rope 2c and the fixed pulley group 3 is increased, thus avoiding failure.

[0028] More importantly, because this application uses a polygonal rope winding part 3d, the friction is increased. When the lifting control handle 2b moves up and down, the fixed pulley group 3 will collide with the horizontal frame 1a due to the installation gap after assembly, affecting the service life of the horizontal frame 1a and the fixed pulley group 3. To avoid the above problem, this application provides a snap-fit ​​part 3c 1 on one side of the fixed pulley group 3, so that it can be installed on the horizontal frame 1a through the snap-fit ​​part 3c 1, and the two can be snapped and fixed by a tight fit, so that the horizontal frame 1a is connected to the housing 3c of the fixed pulley group 3, avoiding relative displacement between the fixed pulley group 3 and the horizontal frame 1a. Furthermore, the reliability of the connection with the horizontal frame 1a is increased by providing a check plate on the top of the snap-fit ​​part 3c 1.
