[0002] Side-pressure windows, also known as side-pressure sliding airtight windows, are designed to allow the sash to slide horizontally to open and close. When the sash is locked onto the frame, it presses inward against the frame to improve airtightness, thermal insulation, and sound insulation. Existing side-pressure windows use a sliding roller assembly. However, when used with large sashes, the weight of the sash causes significant sliding resistance between the slider and the base, resulting in uneven sliding and difficulty in opening and closing the sash. Simultaneously, it also creates significant sliding resistance between the actuating rod on the transmission rod and the guide groove on the base, further complicating the opening and closing process and causing excessive wear on the actuating rod, thus affecting the sealing effect.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the following description is provided in conjunction with the appendix. Figure 1-6 Further analysis of this utility model is then conducted.

[0024] like Figure 1-6 As shown, a sliding wheel assembly for a side-pressure window includes a transmission rod 1, a slider 2, a base 3, and a base 4;

[0025] The transmission rod 1 is movably mounted on the slider 2. A toggle rod 11 is fixedly connected to the middle of the transmission rod 1. A guide bearing 12 is rotatably mounted at the bottom of the toggle rod 11. The transmission rod 1 is connected to the handle on the window sash. By rotating the handle, the transmission rod 1 is moved, causing the guide bearing 12 to slide relative to the guide groove 31.

[0026] The slider 2 is slidably mounted on the base 3. The middle part of the slider 2 is provided with a guide hole 21 through which the actuating rod 11 and the guide bearing 12 pass. The bottom of the slider 2 is provided with first grooves 22 that are slidably connected to the two sides of the base 3. The slider 2 is fixedly connected to the window sash. When the slider 2 slides relative to the base 3, it drives the window sash to move.

[0027] The base 3 is fixedly mounted on the base 4. The middle part of the base 3 is provided with an S-shaped guide groove 31 that slides with the guide bearing 12 along its length. The two sides of the guide groove 31 are provided with needle roller bearings 32 that slide with the slider 2. The two sides of the base 3 extend with sliding parts 33 that slide with the first groove 22. The bottom of the base 3 is provided with a guide wheel 34 that rotates. The function of the guide wheel 34 is to make the traveling wheel 41 move smoothly in the groove of the window frame without deviation, and at the same time improve the smoothness of the window sash when it is pushed and pulled.

[0028] The base 4 is provided with rotatable wheels 41 on both sides. The base 3 and the base 4 are moved and installed in the slide rail on the window frame through the cooperation of the wheels 41 and the slide rail in the slide rail.

[0029] In this embodiment, preferably, the first groove 22 is arranged along the width direction of the slider 2, and a sliding limit rod 23 is vertically provided in the middle of the first groove 22.

[0030] In this embodiment, preferably, the sliding part 33 is arranged along the width direction of the base 3, the outer side of the sliding part 33 is arranged in a wave-shaped structure, and the middle part of the sliding part 33 is recessed with a sliding limiting groove 35 that cooperates with the sliding limiting rod 23. Through the limiting cooperation between the sliding limiting rod 23 and the sliding limiting groove 35, the sliding range of the slider 2 is limited, so as to avoid the slider 2 moving too much and squeezing the window frame, which would cause structural deformation.

[0031] In this embodiment, preferably, the transmission rod 1 is arranged along the length direction of the slider 2, and its moving direction is in the same direction as the length direction of the slider 2. The transmission rod 1 achieves a transmission connection with the base 3 through the sliding fit between the guide bearing 12 and the guide groove 31.

[0032] In this embodiment, preferably, the guide groove 31 is integrally disposed on the base 3, which not only makes the structure more compact, but also makes the installation more convenient; the guide bearing 12 is slidably disposed in the guide groove 31.

[0033] In this embodiment, preferably, the needle roller bearing 32 is embedded in the base 3, making the structure between the slider 2 and the base 2 more compact; the top of the needle roller bearing 32 is slidably connected to the bottom of the slider 2.

[0034] The working principle of this utility model is as follows: the transmission rod 1 is connected to the handle on the window sash, the slider 2 is fixedly connected to the window sash, and the base 3 and the base 4 are moved and installed in the slide groove on the window frame through the cooperation of the traveling wheel 41 and the slide rail in the slide groove. When the window sash is closed, rotating the handle drives the transmission rod 1 to move, causing the guide bearing 12 to slide relative to the guide slide groove 31. During the movement, the push rod 11 applies a thrust to the guide hole 21, pushing the slider 2 to slide relative to the base 3 and the needle roller bearing 32, thereby causing the window sash to move relative to the frame and press inward, thereby improving airtightness, heat insulation performance and sound insulation effect. The action of opening the window sash is the opposite of the action of closing the window sash.
