Description

Technical Field

[0001] The utility model relates to the field of building doors and windows, in particular to a drainage structure of a lower frame of a sliding door. Background Art

[0002] Chinese Utility Model Publication No. CN203684942U discloses a multifunctional high-rail, deep-fitting, thermally insulated sliding door and window. Multiple drainage channels are arranged horizontally at the bottom of the frame, connected by drainage valves. These channels form a drainage structure through drainage holes at the top, near the outside. The channels are large in length, and the frame rails extend through them, making them unsightly. Furthermore, although multiple drainage channels are arranged at the bottom of the frame, they are not interconnected, which can affect drainage efficiency when wind pressure is excessive. Utility Model Content

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A drainage structure for a lower frame of a sliding door, comprising a groove-shaped outer frame and a drainage groove disposed within a cavity of the outer frame, wherein the outer frame has a first guide rail and a second guide rail that are separated from each other and extend in parallel, and the drainage groove is located between the first guide rail and the second guide rail and forms an upper cavity and a lower cavity within the outer frame that are separated from each other;

[0006] In a preferred embodiment of the present invention, the drainage trough is further provided with a first drainage outlet and a second drainage outlet connecting the upper cavity and the lower cavity, the first drainage outlet is opened close to one side of the first guide rail, and the second drainage outlet is opened close to one side of the second guide rail.

[0007] In a preferred embodiment of the present invention, ribs are provided at the bottom of the drainage trough, and the ribs separate the lower cavity into a first lower cavity and a second lower cavity. A flow port connecting the first lower cavity and the second lower cavity is also provided on the ribs.

[0008] In a preferred embodiment of the present invention, the drainage trough and the outer frame are separate.

[0009] In a preferred embodiment of the present invention, the outer edge of the drainage groove has side protrusions extending toward the first guide rail and the second guide rail respectively.

[0010] In a preferred embodiment of the present invention, it further comprises a water retaining block which is arranged at the end of the drainage groove and divides the groove into a plurality of mutually unconnected sections, and an adhesive sealing layer is provided between the groove and the water retaining block.

[0011] The beneficial effects of the present invention are:

[0012] The utility model provides a drainage structure for the lower frame of a sliding door. On the one hand, a drainage groove is set between two guide rails to reduce the area of ​​the drainage groove to achieve the purpose of aesthetics. On the other hand, a first drainage port and a second drainage port are set on the inner and outer sides of the drainage groove so that the lower cavity at the bottom is connected to each other. The pressure of the lower cavity is relieved through the second drainage port to ensure drainage efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In the description of the present invention, it should be noted that the terms "up", "down", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. The above description is simplified for the convenience of describing the present invention, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, it cannot be understood as a limitation on the present invention.

[0018] The following describes exemplary embodiments of the present application with reference to the accompanying drawings. However, it should be understood that the present application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide many additional embodiments. In all figures, the same reference numerals represent the same elements or elements with the same function.

[0019] Figure 1 and Figure 2The overall structure of the present invention is shown. The outer frame 10 is groove-shaped, and a pair of first and second rails 11a and 11b are provided on its upper portion, which are parallel to each other. The first and second rails 11a and 11b are used to support and guide the sliding of the door leaf, so the first and second rails 11a and 11b are provided at the top positions on both sides of the outer frame 10. There is a cavity 13 between the first and second rails 11a and 11b, and the cavity 13 is concave downward to form the above-mentioned groove shape. A drainage groove 20 is provided in the cavity 13 to separate the cavity into an upper cavity and a lower cavity. The bottom of the drainage groove 20 is provided with a downwardly protruding rib 21, which extends in the same direction as the first and second rails 11a and 11b along the length direction of the outer frame 10, further dividing the lower cavity. The side close to the first rail 11a is the first lower cavity 13a, and the side close to the second rail 11b is the second lower cavity 13b. A first drain port 23a and a second drain port 23b are also provided on the drainage groove 20. The first drain port 23a is located on the side close to the first track 11a and connects the first lower cavity 13a and the upper cavity. The second drain port 23a is located on the side close to the second track 11b and connects the second lower cavity 13b and the upper cavity.

[0020] Combined with reference Figure 3 A plurality of flow openings 24 spaced apart from each other are provided on the rib 11 to connect the first lower chamber 13a with the second lower chamber 13b, thereby preventing the first lower chamber 13a or the second lower chamber 13b from backflowing due to insufficient drainage.

[0021] When the first track 11a is closer to the outside and the second track 11b is closer to the inside, rainwater from the outside flows directly through the first drain port 23a into the first lower chamber 13a, or flows through the outer sash and into the first lower chamber 13a. Because the first lower chamber 13a and the second lower chamber 13b are interconnected, airflow can be quickly drained from the second drain port 23b, ensuring that rainwater flows normally into the lower chamber without being affected by wind pressure.

[0022] In one embodiment of the present invention, the ribs 11 include a first rib 21a and a second rib 21b, thereby dividing the lower cavity into three sub-cavities, further reducing the influence of wind pressure on drainage.

[0023] In one embodiment of the present invention, a water retaining block 30 is further provided in the cavity 13. Specifically, the water retaining block 30 is arranged at the joint between the outer frame 10 and the cavity or other profiles, and is sealed by applying glue between the water retaining block 30 and the inner wall of the cavity 13. The water retaining block 30 divides the cavity 13 into a plurality of mutually unconnected sections, and drainage grooves 20 are provided in each section.

[0024] It will be understood that although the terms "first," "second," etc. may be used herein to describe different elements, these elements should not be limited by these terms. These terms are merely used to distinguish one element from another. Thus, a first element may be referred to as a second element without departing from the teachings of the present invention.
