Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sliding window technology, specifically referring to a sliding window trolley swing arm stabilization structure. Background Technology
[0002] Sliding windows are widely used due to their space-saving and easy-to-operate features. However, traditional ordinary sliding windows have many drawbacks:
[0003] 1. Poor sealing performance: When ordinary sliding windows are closed, it is difficult for the window sash and the window frame to fit tightly, resulting in poor sealing. This not only affects the sound insulation and heat insulation of the room, reducing living comfort, but may also cause rainwater leakage during windy and rainy weather, damaging interior decorations and items.
[0004] 2. Insufficient stability: Ordinary sliding windows typically rely solely on the lower roller assembly for support and sliding, lacking an effective stabilizing structure. During daily use, when users slide the window sash, it is prone to swaying from side to side. This swaying not only affects the normal use of the window but also causes additional wear and tear on the window hardware, shortening the window's lifespan. Utility Model Content
[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides a stabilizing structure for the sliding window trolley arm, which effectively solves the problem of inconvenient replacement of the carrier plate.
[0006] To achieve the above functions, the technical solution adopted by this utility model is as follows: a sliding window trolley swing arm stabilizing structure, including a trolley with rotatable wheels on both sides for moving along the window frame track, and a fixing member on the trolley for confining the trolley within the track;
[0007] The window sash has a swing arm base and a swing arm. The swing arm base is fixed to the four corners of the window sash. One end of the swing arm is hinged to a trolley, and the other end is hinged to the swing arm base via a pivot. The swing arm base is provided with a swinging component. One end of the swinging component rotates around a circular shaft on the swing arm, and the other end is hinged to the swing arm base via a spring. It is used to drive the opening and closing of the swing arm by spring compression. The swing arm is provided with a positioning point one and a positioning point two.
[0008] The limiting component is fixed to the window frame and has three positioning points and a U-shaped positioning groove.
[0009] Preferably, the rotating shaft is installed in the hole of the swing arm seat. The rotating shaft is T-shaped with a semi-circular bottom structure. Its rotation angle is limited to 0-90° by a limiting point. The limiting point is a protrusion. The semi-circular part of the rotating shaft engages with the protrusion of the limiting point to limit the rotation angle of the swing arm.
[0010] Preferably, the fixing member is rectangular and can rotate to fix the trolley within the track without it falling off.
[0011] Preferably, the swing arm seat forms a multi-point support structure with the swing arm and the trolley to suppress the left and right swaying of the window sash.
[0012] Preferably, the wheels of the trolley are made of a silent material, and the trolley is equipped with a noise reduction structure to reduce noise during the pushing and pulling process.
[0013] Preferably, the two trolleys are connected and fixed together by a connecting rod, which is a rigid rod to ensure that the two trolleys move synchronously.
[0014] The beneficial effects achieved by adopting the above-described structure are as follows:
[0015] 1. When the window sash is closed, the swing arm structure of this application can spring back to achieve a compression seal, so that the window sash and the window frame fit tightly together, achieving a compression seal effect similar to that of a casement window, which effectively improves the sealing performance of the window. This greatly improves the indoor sound insulation and heat insulation effect, reduces the risk of rainwater leakage, and improves the comfort of living and the overall performance of the house.
[0016] 2. By installing pulleys and swing arms at the four corners of the window sash, a more stable support is provided for the window sash. During the pushing and pulling of the window sash, the compression and extension of the spring inside the swing component generates a stable thrust, keeping the window sash stable and preventing left and right swaying. This not only improves the safety of window use, but also reduces wear and tear on hardware accessories and extends the service life of the window.
[0017] 3. When the window sash is opened, it is far away from the window frame, making it easier to slide left and right. With the well-designed sliding mechanism, it effectively reduces the jamming during the sliding process and also reduces the noise generated during the sliding, creating a quieter and more comfortable living environment for users.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.
[0030] like Figure 1-9As shown, the present invention proposes a sliding window trolley swing arm stabilizing structure, including a trolley 011 with rotatable wheels 012 on both sides for moving along the window frame track. The wheels 012 of the trolley 011 are made of a sound-absorbing material, and the track is equipped with a noise reduction structure to reduce noise during the sliding process. The two trolleys 011 are connected and fixed by a connecting rod 050, which is a rigid rod to ensure that the two trolleys 011 move synchronously. The trolley 011 is equipped with a fixing part 013 for confining the trolley 011 within the track. The fixing part 013 is rectangular and can be rotated to fix the trolley 011 within the track to prevent it from falling off.
[0031] like Figure 4 , 5 As shown in Figures 8 and 9, the swing arm seat 031 and the swing arm 021 are fixed at the four corners of the window sash. The swing arm seat 031 forms a multi-point support structure with the trolley 011 through the swing arm 021 to suppress the left and right swaying of the window sash. One end of the swing arm 021 is hinged to the trolley 011, and the other end is hinged to the swing arm seat 031 through the pivot 032. The swing arm seat 031 is provided with a swing member 034. One end of the swing member 034 rotates around the round shaft 036 on the swing arm 021, and the other end is hinged to the swing arm seat 031 through the spring 035. It is used to drive the opening and closing of the swing arm 021 by spring compression. The swing arm 021 is provided with positioning point 1 022 and positioning point 2 023.
[0032] like Figure 4 , 6 As shown, the rotating shaft 032 is installed in the hole of the swing arm seat 031. The rotating shaft 032 is T-shaped with a semi-circular bottom structure. Its rotation angle is limited to 0-90° by the limiting point 033, which is a protrusion. The semi-circular part of the rotating shaft 032 engages with the protrusion of the limiting point 033 to limit the rotation angle of the swing arm 021.
[0033] like Figure 1 , 6 As shown in Figure 8, the limiting component 040 is fixed to the window frame and has a positioning point 3 041 and a U-shaped positioning groove 042.
[0034] In practical use, when it is necessary to open the window sash, pull the window sash, and the swing arm 021 rotates around the hinge point with the trolley 011 under the action of the pulling force. At this time, the swing component 034 pushes the swing arm 021 to rotate outward and open under the compression of the spring 035. The opening angle of the swing arm 021 is controlled by the engagement of the semi-circular disc at the bottom of the rotating shaft 032 and the protrusion limit 033. When the maximum opening angle is reached, the window sash is away from the window frame and the window frame is perpendicular to the window sash. At this time, the window sash can be pushed and pulled left and right to move.
[0035] When the window sash needs to be closed, the sliding window sash causes the positioning point 022 on the trolley 011 to collide with the positioning point 3 041 fixed on the window frame. With the positioning point 3 041 as the rotation center, the swing arm 021 rotates around it to close the window sash. During the closing process, the positioning cylindrical protrusion 023 on the swing arm 021 slides into the U-groove 042 fixed on the window frame, realizing the accurate positioning and fixation of the window sash, completing the closing action, ensuring that the window sash is closed tightly, and achieving a compression sealing effect.
[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
