[0023] The utility model provides a kind of connecting structure of suspended sliding window double row wheel, solve the problem that existing structure connection stability and sealing effect are not good, better realize fixed connection by the connecting structural member of improvement design, simultaneously guarantee sealing effect.

[0024] Please refer to Figures 3 to 5 The utility model discloses a kind of connecting structure of suspended sliding window double row wheel, including the connecting structural member 3 for being connected with movable sash 1 and double row wheel 2.The connecting structural member 3 is preferably profile arranged transversely.The upper end of connecting structural member 3 has transverse clamping block 31, and the lower end of movable sash 1 has transverse clamping groove 13, and transverse clamping groove 13 is C-shaped with opening downwards, and transverse clamping block 31 is embedded in transverse clamping groove 13.The lower side of connecting structural member 3 is connected with transverse arm 32, and the two ends of transverse arm 32 are provided with transverse wool groove 33, and the lower side of transverse arm 32 is connected with middle vertical plate 34, and the lower side of middle vertical plate 34 is connected with double row wheel mounting groove 35, and double row wheel 2 is connected with double row wheel mounting groove 35.

[0025] The double-row wheels 2 are arranged in pairs on the tracks 41 in the window frame 4, the window frame 4 has a plurality of cover plates 5 arranged side by side, and the cover plates 5 have gaps therebetween, the gaps correspond to the upper portions of the tracks 41, the middle vertical plates 34 are located in the gaps, and the gaps between the two sides of the middle vertical plates 34 and the cover plates 5 allow the connecting structure 3 to move along the tracks 41 in the gaps, that is, to realize the sliding movement of the movable sash. The transverse wool groove 33 is located above the cover plate 5, the transverse wool groove 33 opens downward, the transverse wool groove 33 is provided with wool and forms a seal with the cover plate 5. Preferably, the transverse wool groove 33 and the wool on both sides of the middle vertical plate 34, that is, on both sides of the gap, are used to realize sealing, so that a seal is formed on the outdoor side and the indoor side when the sash is closed.

[0026] Please refer to Figure 4 , further, the upper end of the transverse clamping block 31 is provided with a screw groove 311 opening upward, and a flat-end fixing screw 312 is inserted therein, and the flat-end fixing screw 312 abuts against the transverse clamping block 31 and the movable sash 1. The transverse clamping block 31 is a clamping block with a T-shaped cross section, and the two ends of the transverse portion correspond to the two ends of the transverse clamping groove 13. In some embodiments, the transverse clamping block 31 and the transverse clamping groove 13 are completely matched in shape, for example, forming a tight fit, but this way requires higher requirements for profile production and installation; or can be fixed by screws or adhesives, but the operation is not very convenient; in the preferred embodiment shown in the figure, the thickness of the transverse clamping block 31 is slightly smaller than that of the transverse clamping groove 13, for example, forming a clearance fit, which is convenient for production and installation, and then the flat-end fixing screw 312 is screwed into the end of the profile, so that the overall structure is tightly pressed against each other, and the thread engagement is stable, ensuring the fixing effect.

[0027] More specifically, the movable sash 1 is a broken-bridge heat insulation profile structure, including a first sash profile 11 and a second sash profile 12 connected by a heat insulation strip 14, and the first sash profile 11 and the second sash profile 12 have a blocking arm on the side away from the connecting structure 3 (the upper side in the figure) Figure 4 , so as to form a notch for fixing the window glass. Among the first sash profile 11 and the second sash profile 12, the cross-sectional width of the first sash profile 11 is greater than that of the second sash profile 12, and the transverse clamping groove 13 is completely located on the first sash profile 11. Therefore, in terms of cross-sectional shape, the connecting structure 3 is generally aligned with the movable sash 1 in the middle, while the transverse clamping block 31 is offset to one side, and the connecting structure 3 does not form a close surface contact with the second sash profile 12, which makes the connecting structure 3 not to damage the heat broken bridge structure between the first sash profile 11 and the second sash profile 12, and can ensure the heat insulation effect.

[0028] The double-row wheel 2 is a present accessory and is a component including a roller, a shaft, a shaft support, etc. The shaft support is generally in a square structure and has a through hole to facilitate installation and fixation.

Correspondingly, in the cross-sectional shape of the connecting structure 3, the cross-sectional shape of the middle vertical plate 34 is that the lower end width gradually increases and forms a cavity 341 for connecting the screw 342. The cavity 341 is, for example, trapezoidal or triangular. During installation, the screw 342 penetrates through the bottom plate of the cavity 341 into the cavity 341 and can be tightly fixed, thereby stably connecting the double-row wheel 2.

[0029] The cover plate 5 is one of the characteristics of the suspended sliding window. The bottom of the cover plate 5 has a cover plate connecting part 51 for connecting with the window frame 4, thereby covering most of the area above the track 41 and leaving one or more gaps for the connecting structure 3 to pass through. In actual use, after the movable sash is opened, the bottom of the window frame is a whole flat cover plate, rather than exposing the track as in the traditional sliding window. Further preferably, the cover plate 5 has a cover plate wool groove 52 on both sides, so that in the gap, the wool is arranged in the cover plate wool groove 52 and forms a seal with the side surface of the middle vertical plate 34, further ensuring the sealing and stability effect.

[0030] Please refer to Figures 1 to 3 、 Figure 6 、 Figure 7 ( Figure 2 The right side in Figure 6 、 Figure 7 The lower side in

[0031] In conclusion, the utility model discloses a kind of connecting structure of typical double-row wheel of suspended sliding window, and window sash is connected by connecting structural member between double-row wheel.The upper end of connecting structural member is matched with the shape of the slot of window sash, and it is inserted into the slot of window sash, then flat end set screw is inserted into the slot hole of connecting structural member, and the window sash slot is connected and fixed with connecting structural member by continuously rotating flat end set screw into slot hole.The middle position of connecting structural member is a narrow strip-shaped vertical plate, and there is only a gap between the cover plates after installing the track cover plate, so the middle part of connecting structural member can move in the gap, and the exposed area of connecting structural member is small.The lower end of connecting structural member is trapezoidal, and this position is used to install screws to connect the lower end of connecting structural member with double-row wheel.In addition, a wool slot is provided below the connecting structural member, and a seal is formed between the wool and the cover plate after installing the wool.Therefore, this scheme can ensure better sealing effect and more stable connection and fixing effect.
