DETAILED DESCRIPTION

[0033] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0034] refer to Figures 1 to 5 , a drip-proof structure that can be applied to doors and windows;

[0035] refer to Figure 1 , the anti-drip structure comprises a sash window frame 1 and a first frame 2;

[0036] The sash window frame 1 comprises a first profile 11, a first heat insulating strip 12, a second heat insulating strip 13 and a second profile 14;

[0037] The first frame 2 includes a third profile 21, a third heat insulation strip 22 and a fourth profile 23;

[0038] A sealing strip 3 is provided between the second thermal insulation strip 13 and the third thermal insulation strip 22;

[0039] The space enclosed by the first profile 11, the sealing strip 3 and the third profile 21 is a water collecting chamber 4;

[0040] The third profile 21 is provided with a drainage groove 210, and the top wall of the drainage groove 210 is provided with a drainage hole 2101 communicating with the water collecting chamber 4;

[0041] A water guiding slope 31 is provided on one side of the sealing strip 3 close to the water collecting chamber 4;

[0042] refer to Figure 2 and Figure 3 A first drip edge 11a is provided on one side of the first profile 11 close to the sealing strip 3. The first drip edge 11a faces the water guide slope 31 in the vertical direction. Water flows to the first drip edge 11a and drips downward to the water guide slope 31 under the action of the first drip edge 11a, and finally flows to the drainage groove 210. Therefore, the first drip edge 11a can prevent water from flowing to the inner side of the room, and is conducive to the formation of water drops on the water guide slope 31, thereby improving the waterproof performance and achieving better drainage effect.

[0043] A second drip edge 11b is provided on one side of the first profile 11 away from the sealing strip 3. The second drip edge 11b faces the drainage groove 210 in the vertical direction. The setting of the second drip edge 11b can prevent water from flowing to the inside of the room and promote water to flow or drip to the drainage groove 210, thereby improving the drainage effect.

[0044] refer to Figure 3 The first heat-insulating strip 12 is provided with a first flange 121 extending upward, which can prevent water vapor or water flow to the inner side of the room to a certain extent, thereby improving the sealing performance;

[0045] The second heat-insulating strip 13 is provided with a second flange 131 extending downward, and the second flange 131 abuts against the top of the sealing strip 3 to form a sealed connection.

[0046] refer to Figure 3 The inclination angle θ of the water guiding slope 31 is between 15 degrees and 30 degrees, so that water can be quickly guided to the drainage groove 210.

[0047] refer to Figure 4 and Figure 5 The sash window frame 1 also includes a pressing line 5 , which is connected to the first profile 11 .

[0048] The pressing line 5 includes a first wall 5a, a second wall 5b, a third wall 5c, a first hook 51 and a second hook 52 which are connected in sequence;

[0049] The first wall 5a is perpendicular to the second wall 5b, and the third wall 5c is inclined;

[0050] A second hook 52 is disposed on a side of the first hook 51 away from the latch 510;

[0051] Therefore, the setting of the third wall 5c enables the pressing wire 5 to form a closed structure, which can improve the strength of the pressing wire 5 and reduce deformation, and the first hook 51 and the second hook 52 are closely connected, that is, directly connected together, reducing the setting of the connecting wall between the two hooks, which is conducive to reducing materials. In combination with the setting of the inclined third wall 5c, materials are further reduced, costs are reduced, and the size of the pressing wire 5 is smaller, occupying less space, and is more suitable for narrower window frames or door frames.

[0052] The first hook 51 is arc-shaped, and the second hook 52 is right-angled.

[0053] refer to Figure 5 The first profile 11 is provided with a first slot 111, and the slot of the first slot 111 is provided with a first buckle position 112 and a second buckle position 113 which are arranged oppositely;

[0054] The first buckle position 112 is connected to the first hook 51, and the second buckle position 113 is connected to the second hook 52;

[0055] Therefore, the first profile 11 only needs to be provided with one groove body to be assembled with the pressing wire 55 , and there is no need to provide two groove bodies, which is conducive to simplifying the structure.

[0056] The length dimension W1 of the second wall 5b is greater than the width dimension W2 formed by the first hook 51 and the second hook 52, wherein the dimension W2 is between 8 and 10 mm. The pressing line 5 is roughly triangular in shape, has high structural strength, and occupies little space.

[0057] A door and window includes the above-mentioned anti-drip structure. The first profile 11 of the sash frame 1 is provided with a first drip edge 11a to prevent water from flowing to the indoor side and can form water drops to the water guide slope 31, thereby improving the sealing and waterproof performance and achieving better drainage effect.

[0058] The above disclosure is only some embodiments of the utility model. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the utility model, and these all belong to the protection scope of the utility model.
