Description

Technical Field

[0001] This utility model relates to the technical field of door and window hardware, and in particular to a side-pressure pulley mechanism and window frame that are easy to install. Background Technology

[0002] Traditional side-pressure windows typically employ a pulley mechanism consisting of a pulley assembly that slides within the window frame profile and a side-pressure transmission assembly that is connected to the window sash profile. These two components are slidably connected via the sliding assembly. While this structure ensures pulley stability during window sash opening and closing, it has significant drawbacks in actual installation. Because the sliding assembly needs to be fixed to the window sash profile, while the side-pressure transmission assembly needs to slide within the window frame profile, the relative positional accuracy between them is extremely high. Inaccurate positioning during installation can lead to poor sliding of the pulley assembly within the window frame profile, or even jamming. Current technology lacks an effective pre-positioning mechanism, often requiring installers to repeatedly adjust the mechanism to achieve the ideal fit. This not only increases installation difficulty and labor costs but also easily causes wear and tear on components due to repeated adjustments. Especially in high-altitude work environments, this repeated adjustment is both dangerous and inefficient. Furthermore, the positioning of existing pulley mechanisms perpendicular to the pulley sliding direction is unreliable, easily causing deviations in the window sash's trajectory. Therefore, existing technology urgently needs improvement to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a side-pressure pulley mechanism that is easy to install, so as to solve at least some of the above-mentioned technical problems.

[0004] The first aspect of this utility model provides an easy-to-install side-pressure pulley mechanism, including a pulley assembly, a sliding assembly, a side-pressure transmission assembly, and a pre-positioning component. The pulley assembly is used to slide into a window frame profile. One end of the sliding assembly is used to connect into a window sash profile, and the other end of the sliding assembly is used to connect to the pulley assembly. The side-pressure transmission assembly is located within the window sash profile and connected to the sliding assembly, and is used to apply a force to the sliding assembly to adjust the relative position between the side-pressure transmission assembly and the pulley assembly. The pre-positioning component includes a first positioning part and a second positioning part. The first positioning part is used to be inserted into the sliding assembly, and the second positioning part is used to be inserted into the side-pressure transmission assembly to achieve pre-positioning of the side-pressure pulley mechanism in the sliding direction of the pulley assembly during installation.

[0005] Optionally, the sliding assembly includes a sliding connecting frame and a sliding seat. The sliding connecting frame is connected to the pulley assembly, and the sliding seat is used to connect to the window sash profile. The sliding connecting frame and the sliding seat are slidably connected in a direction perpendicular to the sliding of the pulley assembly, and the first positioning part is connected to the sliding seat.

[0006] Optionally, the side pressure transmission assembly includes a side pressure column and a transmission bar. The transmission bar is connected to external transmission hardware and has a side pressure groove. The side pressure column is connected to the sliding connecting frame and passes through the sliding seat before being inserted into the side pressure groove. The second positioning part is connected to the transmission bar.

[0007] Optionally, the sliding seat is provided with a positioning protrusion, which is used to insert into the window sash profile to achieve pre-positioning in a direction perpendicular to the sliding direction of the pulley assembly.

[0008] Optionally, the pre-positioning component further includes an operating handle, which is connected to the first positioning part and the second positioning part respectively.

[0009] Optionally, the operating handle, the first positioning part, and the second positioning part are integrally formed.

[0010] Optionally, the first positioning part includes two elastic positioning buckles, which are simultaneously inserted into the positioning holes of the sliding component to achieve positioning of the sliding component.

[0011] Optionally, the pulley assembly is an upper pulley assembly.

[0012] Optionally, the pulley assembly is a lower pulley assembly.

[0013] The second aspect of this solution also provides a window, including a window frame, a window sash, and the aforementioned easy-to-install side-pressure pulley mechanism.

[0014] The beneficial effects of this plan are as follows: By inserting the first and second positioning parts of the pre-positioning component into the sliding assembly and the side pressure transmission assembly respectively, pre-positioning in the sliding direction of the pulley assembly is achieved during installation. This solves the problem of repeated adjustments caused by inaccurate positioning in traditional installation and has the advantages of high installation efficiency and reduced wear of parts.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

For those skilled in the art, the specific meaning of the terms in this utility model can be understood according to the specific circumstances.

[0019] This embodiment discloses a window, including a window frame and a window sash, with a side-pressure pulley mechanism provided between the window frame and the window sash. This window is a side-pressure window; when the window sash is closed to the window frame, it is pressed towards the window frame. The pulley assembly 10 of the side-pressure pulley mechanism slides within the window frame. One end of the sliding assembly 20 is connected to the window sash, and the other end is slidably connected to the pulley assembly 10, thereby ensuring that the pulley assembly 10 is not compressed.

[0020] See Figure 1-3The easy-to-install side-pressure pulley mechanism includes a pulley assembly 10, a sliding assembly 20, a side-pressure transmission assembly 30, and a pre-positioning component 40. The pulley assembly 10 is used to slide into the window frame profile. One end of the sliding assembly 20 is used to connect into the window sash profile, and the other end of the sliding assembly 20 is used to connect to the pulley assembly 10. The side-pressure transmission assembly 30 is located in the window sash profile and connected to the sliding assembly 20. It is used to apply force to the sliding assembly 20 to adjust the relative position between the side-pressure transmission assembly 30 and the pulley assembly 10. The pre-positioning component 40 includes a first positioning part 41 and a second positioning part 42. The first positioning part 41 is used to be inserted into the sliding assembly 20, and the second positioning part 42 is used to be inserted into the side-pressure transmission assembly 30 to achieve pre-positioning of the side-pressure pulley mechanism in the sliding direction of the pulley assembly 10 during installation.

[0021] During installation, the sliding seat 22 is fixed inside the window sash profile, and the pulley assembly 10 is embedded in the track of the window frame profile. The first positioning part 41 of the pre-positioning member 40 is inserted into the positioning hole of the sliding connecting bracket 21, and the second positioning part 42 is inserted into the positioning groove of the transmission bar 32, so that the two maintain a fixed distance in the sliding direction of the pulley. At this time, the side pressure transmission assembly 30 is operated to drive the sliding connecting bracket 21 to move, which drives the pulley assembly 10 to slide along the window frame profile. After debugging, the pre-positioning member 40 is removed to ensure normal operation of the mechanism. This application pre-fixes the relative positions of the sliding assembly 20 and the side pressure transmission assembly 30 during the installation stage to avoid the waste of time caused by repeated debugging. The plug-in structure of the pre-positioning member 40 ensures the consistency of the initial positions of the two in the direction of pulley movement, reducing the problem of pulley jamming caused by assembly deviation. After installation, removing the pre-positioning member 40 will not affect the operation of the mechanism, achieving a balance between rapid positioning and reliable transmission.

[0022] In this embodiment, the sliding assembly 20 includes a sliding connecting frame 21 and a sliding seat 22. The sliding connecting frame 21 is connected to the pulley assembly 10, and the sliding seat 22 is used to connect to the window sash profile. The sliding connecting frame 21 and the sliding seat 22 are slidably connected in a direction perpendicular to the sliding of the pulley assembly. The first positioning part 41 is connected to the sliding seat 22. This application achieves pre-positioning of the sliding assembly 20 in the direction perpendicular to the movement of the pulley, effectively avoiding pulley jamming caused by assembly errors between the window sash profile and the window frame profile. During installation, the slidable mating structure of the sliding connecting frame 21 and the sliding seat 22 allows for fine-tuning of the position before final tightening, ensuring assembly accuracy and reducing operational difficulty.

[0023] In this embodiment, the side pressure transmission assembly 30 includes a side pressure column 31 and a transmission bar 32. The transmission bar 32 is connected to external transmission hardware and has a side pressure groove 321. The side pressure column 31 is connected to the sliding connecting frame 21 and passes through the sliding seat before being inserted into the side pressure groove 321. The second positioning part 42 is connected to the transmission bar 32. The transmission bar 32 and the side pressure column 31 form a sliding fit through the side pressure groove 321. When the external transmission hardware drives the transmission bar 32 to move, the side pressure column 31 slides along the groove, causing the sliding connecting frame 21 to move in a direction perpendicular to the sliding direction of the pulley, thereby adjusting the contact pressure between the pulley assembly 10 and the window frame profile. After the second positioning part 42 of the pre-positioning member 40 is inserted into the transmission bar 32, it restricts the lateral displacement of the transmission bar 32 during installation, ensuring that the initial position of the side pressure column 31 and the side pressure groove 321 are accurately aligned.

[0024] In this embodiment, the sliding seat 22 is provided with a positioning protrusion 221, which is used to insert into the window sash profile to achieve pre-positioning in a direction perpendicular to the sliding direction of the pulley assembly 10. During the installation process, the positioning protrusion 221 and the window sash profile are engaged to achieve automatic positioning in the width direction, and the pre-positioning member 40 achieves positioning in the length direction. The two work together to achieve precise positioning and installation of the sliding assembly 20.

[0025] In this embodiment, the prepositioning component 40 further includes an operating handle 43, which is connected to the first positioning part 41 and the second positioning part 42 respectively. The operating handle 43 is a component used to manually control the insertion or disengagement of the positioning part, and can be made of injection-molded plastic or metal stamping. Its function is to provide a force fulcrum to facilitate synchronous operation of the positioning part during installation.

[0026] In this embodiment, the operating handle 43, the first positioning part 41, and the second positioning part 42 are integrally formed. This application achieves consistent movement of the pre-positioning component 40 during operation, avoids assembly errors that may occur with split structures, and improves positioning accuracy; it simplifies the installation process, allowing operators to complete bidirectional positioning by controlling only a single handle, thus enhancing structural reliability.

[0027] In this embodiment, the first positioning part 41 includes two elastic positioning buckles 411. The two positioning buckles 411 are simultaneously inserted into the positioning holes of the sliding component 20 to achieve positioning of the sliding component 20. The positioning buckle 411 is a snap-fit ​​component with elastic deformation capability, specifically made of plastic or spring steel, with a barb structure at its end. When inserted into the positioning hole, it undergoes elastic deformation to generate a clamping force. This feature enhances positioning stability through the simultaneous insertion of the two buckles, avoiding the misalignment problem caused by single-point fixing.

[0028] In this embodiment, the pulley assembly 10 is either an upper pulley assembly 10 or a lower pulley assembly 10. The side-pressure pulley mechanism of this solution can be used for either an upper pulley mechanism or a lower pulley mechanism. The difference between the two lies in the specific structure of the pulley assembly 10, while the structure and position of the prepositioning member 40 are not affected.

[0029] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
