Description

Technical Field

[0001] The utility model relates to the technical field of profiles, in particular to a door and window track profile. Background Art

[0002] Sliding doors and windows are opened and closed in a push-pull manner. Most existing sliding doors and windows have less than four leaves. Therefore, the tracks of sliding doors and windows are generally two or three. However, for larger balcony windows, the four windows on the left and right are opened opposite each other or two windows are pushed and pulled. When fully opened, the largest window area is only half of the total area of ​​the balcony window, which affects the ventilation effect. For example, Chinese patents CN220539541U-a drainage aluminum profile suitable for sliding doors and windows and CN220378119U-a wind-noise-resistant door and window lower track profile both have only two tracks. When there are three tracks for sliding doors and windows, one of the tracks is usually installed with a screen fan. In addition, when the track and the profile are integrated, such as CN220539541U, the cross-section of the enlarged head at the top of the track edge is circular, and the angle between the enlarged head and the track edge is close to a right angle, which limits the load-bearing capacity of the track.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Combine the following Figures 1 to 6 , describing a door and window track profile according to an embodiment of the utility model.

[0029] The utility model discloses a door and window track profile, comprising a base frame 1 and six guide rails 2 arranged in parallel on the top surface of the base frame 1, wherein the top surface of the base frame 1 is inclined downward from the inside to the outside, and the lower parts of the six guide rails 2 are respectively provided with water holes 3;

[0030] An enlarged guide portion 21 is disposed at the top of the guide rail 2 . The top of the guide portion 21 is arc-shaped, and two side surfaces of the guide portion 21 are vertical planes.

[0031] The door and window track profile of the utility model has six guide rails 2, referring to Figure 2, six or twelve doors and windows can be installed. When used for balcony windows, the window area of ​​the balcony window after it is fully opened is one-sixth of the total area of ​​the balcony window. It can be understood that one of the six guide rails 2 is installed with a screen window, and the other five are installed with doors and windows. Then, the window area of ​​the balcony window after it is fully opened is one-fifth of the total area of ​​the balcony window, which significantly increases the opening of the balcony window and greatly improves the ventilation effect. In addition, the top of the guide part 21 is arc-shaped and the two sides are planes, which can increase the angle at the connection between the guide part 21 and the guide rail 2, thereby improving the firmness of the guide part 21 on the guide rail 2, and then improving the load-bearing capacity of the guide rail 2. The top surface of the base frame 1 is tilted downward from the inside to the outside, and the lower parts of the six guide rails 2 are respectively provided with water holes 3. When rainwater enters the top of the guide rail 2 profile, the rainwater on the inside can flow out through the water holes 3, achieving the effect of preventing water accumulation and preventing water from entering the room.

[0032] Reference Figure 3 In one embodiment, the bottom of the guide portion 21 is connected to the side of the guide rail 2 through an inclined surface, and the angle α between the two inclined surfaces at the bottom of the guide portion 21 is 70-80°, so that the guide portion 21 is firmly connected to the guide rail 2, and the guide rail 2 has a good load-bearing capacity. Preferably, the angle α between the two inclined surfaces at the bottom of the guide portion 21 is 75°.

[0033] Preferably, a plurality of vertical reinforcing plates 11 are provided in the base frame 1 to improve the load-bearing capacity of the base frame 1 and strengthen the supporting effect of the base frame 1 on the guide rail 2 .

[0034] Further preferably, the thickness of the guide rail 2 and the reinforcing plate 11 are both greater than the thickness of the top plate 17 of the base frame 1. Therefore, the guide rail 2 and the reinforcing plate 11 have higher strength and are not easily deformed by the pressure of door and window sashes.

[0035] Specifically, in one embodiment, there are two reinforcing plates 11, and two guide rails 2 are corresponding between the two reinforcing plates 11. The thickness of the guide rails 2 and the reinforcing plates 11 are both 2.0 to 2.5 mm, and the thickness of the top plate 17 of the base frame 1 is 1.2 to 1.5 mm. Based on the staggered arrangement of the reinforcing plates 11 and the guide rails 2, the top plate 17 supported by the two reinforcing plates 11 can have a good supporting effect on the six guide rails 2, and can also simplify the profile structure to reduce the difficulty of designing the extrusion molding die of the profile. By limiting the thickness of the guide rails 2, the reinforcing plates 11 and the top plate 17 of the base frame 1, the profile can achieve sufficient load-bearing capacity while using less material.

[0036] In one embodiment of the utility model, the top surface of the inner side of the base frame 1 is provided with an inner baffle 12 and / or the top surface of the outer side of the base frame 1 is provided with an outer baffle 13, the outer baffle 13 is provided with a water hole 3, and the top surface of the outer baffle 13 is lower than the top surface of the inner baffle 12. The outer baffle 13 and the inner baffle 12 have the functions of blocking dust and water. In one embodiment, a baffle is provided on the top surface of the inner side of the base frame 1 to prevent rainwater on the top of the guide rail 2 profile from entering the room; refer to Figure 4 In another embodiment, baffles are respectively provided on the inner top surface and the outer top surface of the base frame 1. The two baffles can not only prevent rainwater on the top of the guide rail 2 profile from entering the room, but also have the function of blocking wind and dust.

[0037] Reference Figure 5 In one embodiment of the utility model, the top ends of the six guide rails 2 are flush, and a cover plate 4 is arranged between at least one group of two adjacent guide rails 2. The cover plate 4 is close to the outside of the base frame 1, and the cover plate 4 is provided with a water hole 3. Based on the inclined setting of the top surface of the door and window guide rail 2 profile and the flush top ends of the six guide rails 2, the guide rail 2 located on the outside has a greater height, and the cover plate 4 supports the guide rail 2, so that the guide rail 2 is not easy to tilt. Exemplarily, the side of the guide rail 2 has a convex ridge, and the edge of the cover plate 4 has a groove, so that the convex ridge is inserted into the groove to achieve the installation of the cover plate 4.

[0038] Reference Figure 6 In one embodiment of the utility model, the two reinforcing plates 11 divide the base frame 1 into an inner cavity 14, a middle cavity 15 and an outer cavity 16; the top plate 17 and the outer plate 18 of the base frame 1 are respectively provided with water holes 3, and the water holes 3 of the top plate 17 of the base frame 1 are located at the top of the outer cavity 16. The water holes 3 of the top plate 17 of the base frame 1 play a diversion role for rainwater, and guide the rainwater between the inner guide rails 2 into the outer space and discharge it, which is conducive to quickly draining the rainwater on the top of the base frame 1. Exemplarily, the water holes 3 are long holes.

[0039] Other structures and operations of a door and window track profile according to an embodiment of the utility model are known to ordinary technicians in the field and will not be described in detail here.
