[0048] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0050] See Figures 1-10This embodiment discloses an integrated side-pressure pulley, including a corner frame 2, a spring piece 4, a connecting block 3, a base 1, a driving component 9, and a pulley assembly. The base 1 is connected to the corner frame 2, and the corner frame 2 is provided with a connecting step 201. The base 1 is provided with a corresponding connecting through hole 101. The two can be riveted or connected by accessories to form a fast connection, thus forming a whole. The spring piece 4 is disposed on the corner frame 2, and the connecting block 3 connects the spring piece 4 and the driving component 9. The pulley assembly includes a slide seat 10 and a roller 6, with the roller 6 rotatably connected to the slide seat 10. The base 1 is provided with at least two support shafts 7, which extend along the translational direction. The slide seat 10 is slidably disposed on each support shaft 7. The driving component 9 cooperates with the slide seat 10. When the spring piece 4 moves, it drives the driving component 9 to move, thereby causing the slide seat 10 and the base 1 to translate relative to each other.

[0051] Furthermore, the base 1 has an inner cavity 102, and both ends of each support shaft 7 are connected to the two sides of the inner cavity 102 of the base 1, respectively. The slide 10 is disposed in the inner cavity 102 of the base 1. Each slide 10 and each support shaft 7 has a corresponding connecting hole 1002, and each support shaft 7 passes through the corresponding connecting hole 1002. The support shaft 7 passing through the connecting hole 1002 of the slide 10 can not only support the slide 10, but also limit the movement direction of the slide 10, which helps to improve stability.

[0052] To ensure more even force distribution on the slide block 10 and improve the feel during translational operation, this embodiment includes two support shafts 7, located on either side of the roller 6. Of course, the number of support shafts 7 can be flexibly adjusted according to actual needs, and is not limited to this.

[0053] Furthermore, a rolling assembly is provided in the connecting hole 1002. The pulley assembly includes a retainer 14 and several rolling elements 15, which are confined in the retainer 14 and arranged along the translational direction. In this embodiment, the rolling elements 15 can be accessories such as balls or rollers. By setting the rolling assembly, the relative translation between the slide block 10 and the support shaft 7 is smoother, the friction between them is reduced, making the translational operation more convenient and providing a better feel.

[0054] Of course, in addition to using the above-mentioned rolling components to reduce the friction between the slide block 10 and the support shaft 7, a bushing with a low coefficient of friction can also be selected and placed in the connecting hole 1002 to cooperate with the support shaft 7.

[0055] To enable the driving component 9 to drive the slide 10 to translate, this embodiment provides two linkage components 11 on the slide 10. The driving component 9 has a driving groove 903 that cooperates with the linkage component 11. The driving groove 903 extends at an angle, and its extension direction is at a certain angle to the moving direction of the driving component 9. The linkage component 11 is embedded in the driving groove 903. When the driving component 9 moves with the spring 4, the driving groove 903 causes the linkage component 11 to drive the slide 10 to move along the translational direction. In this embodiment, the two linkage components 11 are located on both sides of the rolling element, ensuring balanced force on the slide 10 and allowing the slide 10 and the rolling element to translate smoothly. The linkage component 11 adopts a pin structure and is riveted to the slide 10. Correspondingly, the driving component 9 also has two driving grooves 903.

[0056] Furthermore, the slide 10 is provided with a mounting cavity 1001, and the roller 6 is disposed in the mounting cavity 1001 and connected to the two side walls of the mounting cavity 1001 via a mounting shaft 12. In this embodiment, the mounting shaft 12 can be configured to be rotatably connected to the side wall of the mounting cavity 1001 to realize the rotation of the roller 6, or the mounting shaft 12 can be configured to be fixedly connected to the mounting cavity 1001, in which case the connection between the mounting shaft 12 and the roller 6 is configured to be rotatable, for example, through a bearing. In addition, in this embodiment, the roller 6 extends out of the slide 10, and a clearance groove 902 is provided at the corresponding position of the driving member 9 and the roller 6.

[0057] In this embodiment, multiple spring pieces 4 are provided and overlap each other, and a first hole 401 is provided at one end near the driving member 9. The other end of the spring piece 4 is connected to the transmission component or other components of the hardware system. For example, the user can rotate the handle on the door or window to drive the movement of the spring piece 4 through the transmission component. The driving member 9 has a second hole 901 at one end near the spring piece 4. The connecting block 3 has a first protrusion 301 and a second protrusion 302. The first protrusion 301 is embedded in the first hole 401, and the second protrusion 302 is embedded in the second hole 901. By connecting the first protrusion 301 and the second protrusion 302 on the connecting block 3 to the first hole 401 and the second hole 901 on the spring piece 4 and the driving member 9 respectively, the connecting block 3 is simultaneously connected to the spring piece 4 and the driving member 9. The structure is simple, reliable, and easy to assemble.

[0058] In addition, the corner unit in this embodiment is provided with a groove 203 near the driving member 9. When the driving member 9 moves to the rotating side, it can enter the groove 203 to avoid interference between the two and to allow the driving member 9 and the corner unit to cooperate better. At the same time, a sliding groove 202 is also provided on the corner unit for the sliding of the connecting block 3.

[0059] Furthermore, the pulley assembly also includes a guide wheel 13, which is mounted on the slide block 10, and the rotation direction of the guide wheel 13 is perpendicular to the rotation direction of the roller 6. Figure 2As shown, this embodiment has two guide wheels 13, which are located at both ends of the slide block 10 and on both sides of the roller 6.

[0060] To facilitate assembly and positioning, the base 1, drive component 9, and slide 10 of this embodiment are respectively provided with a coaxial first positioning hole 103, a second positioning hole 904, and a third positioning hole 1003. During assembly, the pulley assembly and drive component 9 can be accurately positioned in their initial positions by using the three positioning holes. Simply insert the positioning component 8 into the three positioning holes; the operation is simple.

[0061] This embodiment also discloses a window, including the aforementioned integrated side-pressure pulley; other parts of the hardware system can be found in the prior art.

[0062] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
