Description

Technical Field

[0001] This utility model relates to the technical field of sliding doors and windows, and in particular to a sliding window track structure. Background Technology

[0002] Sliding windows are a common type of window, widely used due to their advantages such as not taking up indoor space, flexible opening, and low price. Traditional sliding windows are usually composed of window frames, sash frames, glass, and rollers. The window frame includes an upper track and a lower track. Generally, the installation of a sliding window involves first inserting the top of the sash frame upwards into the upper track of the window frame, then aligning the sash frame so that the bottom corresponds to the lower track of the window frame, and finally placing the bottom of the sash frame into the lower track. The existing sash frame then slides linearly through the guide rails and rollers of the lower track. However, this sliding window structure has certain defects: if the lower track is not installed evenly or there are foreign objects, it will affect the smoothness of the sash frame sliding, and may even cause the sash frame to fall off the window frame. Utility Model Content

[0003] The present invention provides a sliding track structure for a sliding window to solve the problems mentioned above.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sliding window track structure, including a window frame and a sash frame. The window frame includes a track, and the bottom of the track is provided with a guide strip (a). Both sides of the track are provided with guide strips (b). The bottom of the sash frame is provided with a pulley profile, which includes an upper connecting part and a lower sliding part. A connecting plate is provided between the upper connecting part and the lower sliding part. The pulley profile is provided with a load-bearing pulley slidably connected to the guide strip (a) and an anti-sway pulley slidably connected to the guide strip (b). A baffle is provided above the two guide strips (b) to prevent the lower sliding part from disengaging from the track. There is a gap between the two baffles, and the connecting plate is disposed within the gap.

[0005] Furthermore, the upper connecting part is fixedly connected to the bottom of the fan frame by connecting screws.

[0006] Furthermore, the upper connecting part includes a first horizontal plate that abuts against the lower side of the fan frame and a connecting frame disposed in the middle of the upper part of the first horizontal plate. The top of the connecting frame is provided with a slot. The two sides of the first horizontal plate are respectively located above the two baffles. The lower side of the fan frame is provided with a recess. The connecting frame is disposed in the recess. The connecting screw is disposed in the slot.

[0007] Furthermore, the lower sliding part has a T-shaped cross section and includes a second horizontal plate and a vertical frame part disposed in the middle of the lower side of the second horizontal plate. The two sides of the second horizontal plate are respectively located below the two baffles.

[0008] Furthermore, the anti-sway wheel is fixedly connected to the second horizontal plate by screws, and the load-bearing pulley is fixedly connected to the vertical frame by screws.

[0009] Furthermore, the slide rail has slots on both sides that are slidably connected to the baffle, and one side of the baffle has a hooking edge that is hooked to the slot opening.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the fan frame uses load-bearing pulleys and anti-sway wheels to cooperate with guide bars a and b set in the slide rail. The guide bar b and anti-sway wheels prevent the fan frame from shifting laterally, ensuring the smooth sliding of the fan frame. Furthermore, a baffle is set above the guide bar b, which restricts the upward displacement of the lower sliding part, thereby preventing the pulley profile from falling off and sliding with the slide rail.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] As shown in the attached diagram, the sliding rail 10 structure of a sliding window of this utility model includes a window frame 1 and a sash frame 2. The window frame 1 includes a sliding rail 10. A guide bar 101 (a) is provided at the bottom of the groove inside the sliding rail 10, and guide bars 102 (b) are provided on both side walls inside the sliding rail 10. A pulley profile 20 is provided at the bottom of the sash frame 2. The pulley profile 20 includes an upper connecting part 21 and a lower sliding part 22. A connecting plate part 23 is provided between the upper connecting part 21 and the lower sliding part 22. The pulley profile 20 is provided with a load-bearing pulley 24 slidably connected to the guide bar 101 (a) and an anti-sway wheel 25 slidably connected to the guide bar 102 (b). The anti-sway wheel 25 abuts against the guide bar 102. To prevent lateral displacement of the sash frame 2 and ensure that the sash frame 2 slides in a straight line along the length of the slide rail 10, thereby improving the smoothness of the sash frame 2's sliding, a baffle 11 is provided above the two b guide bars 102 to prevent the lower sliding part 22 from disengaging from the slide rail 10. This baffle 11 prevents impurities from entering the interior of the slide rail 10, thereby ensuring that the sliding environment of the sash frame 2 is not affected. There is a gap 100 between the two baffles 11, and the connecting plate part 23 is provided in the gap 100. The top and bottom of the window frame 1 are both slide rails 10. The top slide rail 10 does not have a guide bar 101, but only a b guide bar 102. The top of the sash frame 2 is also provided with an anti-sway wheel 25 that cooperates with the b guide bar 102.

[0019] This utility model discloses a sliding window track 10 structure. The sash frame 2 uses a load-bearing pulley 24 and an anti-sway wheel 25 to cooperate with the a guide bar 101 and b guide bar 102 provided in the track 10. The b guide bar 102 and the anti-sway wheel 25 prevent the sash frame 2 from shifting laterally, ensuring the smooth sliding of the sash frame 2. Furthermore, a baffle 11 is provided above the b guide bar 102 to restrict the upward displacement of the lower sliding part 22, thereby preventing the pulley profile 20 from falling off and sliding with the track 10.

[0020] As shown in the figure, the upper connecting part 21 is fixedly connected to the bottom of the fan frame 2 by connecting screws. The connecting screws pass through the end of the fan frame 2, and the pulley profile 20 is fixedly installed at the bottom of the fan frame 2 by connecting screws. Specifically, the upper connecting part 21 includes a first horizontal plate 211 that abuts against the lower side of the fan frame 2, and a connecting frame 212 disposed in the middle of the upper side of the first horizontal plate 211. The top of the connecting frame 212 is provided with a slot 2100. The two sides of the first horizontal plate 211 are respectively located above the two baffles 11. The lower middle of the fan frame 2 is provided with a recess, and the connecting frame 212 is disposed in the recess. The connecting screw is disposed in the slot 2100.

[0021] Specifically, the lower sliding part 22 has a T-shaped cross-section. The lower sliding part 22 includes a second horizontal plate 221 and a vertical frame part 222 disposed in the lower middle part of the second horizontal plate 221. The two sides of the second horizontal plate 221 are respectively located below the two baffles 11. The anti-sway wheel 25 is fixedly connected to the second horizontal plate 221 by screws, and the load-bearing pulley 24 is fixedly connected to the vertical frame part 222 by screws. The T-shaped lower sliding part 22 facilitates the installation of the load-bearing pulley 24 and the anti-sway wheel 25. In addition, the second horizontal plate 221 also cooperates with the baffle 11. The two sides of the second horizontal plate 221 are respectively located below the baffle 11. When there are impurities in the slide rail 10 that cause the load-bearing pulley 24 to rise, the baffle 11 will push against the second horizontal plate 221, thereby preventing the lower sliding part 22 from rising. In addition, the baffle 11 is made of plastic material and has a certain degree of elasticity.

[0022] Specifically, the slide rail 10 has slots 1100 on both sides that are slidably connected to the baffle 11. The baffle 11 has a hooking edge 1101 on one side that hooks onto the slot opening of the slot 1100, which facilitates the installation of the baffle 11. The baffle 11 can be inserted into the slot 1100 from the end, and after installation, the hooking edge 1101 can hook onto the slot opening of the slot 1100 to prevent the baffle 11 from falling off.

[0023] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
