Description
Technical Field
[0001] This utility model relates to the field of sliding door technology, and in particular to a sliding door hook lower sealing element with drainage function and a sliding door. Background Technology
[0002] With economic development, people have increasingly higher requirements for living spaces. As doors and windows connect buildings to the external environment, demands for energy efficiency, sealing, and sound insulation are rising. Simultaneously, driven by the national "dual-carbon" goals, door and window manufacturers are aligning their research and development efforts more closely with policy and consumer needs. Sliding doors, as the preferred choice for balcony doors, are receiving increasing attention for their sealing and waterproofing requirements.
[0003] Typically, the sealing block at the bottom of the sliding door's hook and hinge area uses soft foam sealing material, such as PE foam or EPDM foam. This is placed at the overlapping area between the two sliding door hooks and hinges to seal the bottom of the door, but it does not provide drainage. The hook and hinge area is the weakest point in the sealing and waterproofing of sliding doors. Due to inadequate sealing at this point, rainwater can enter the interior of the sliding door under certain wind pressure and cannot drain quickly, resulting in air and water leaks. This causes considerable inconvenience for homeowners using sliding doors. Utility Model Content

Detailed Implementation
[0023] To enhance understanding of this utility model, it will be described in further detail below with reference to the accompanying drawings and embodiments. These embodiments are only used to explain this utility model and do not limit the scope of protection of this utility model.
[0024] Example
[0025] Please refer to Figures 1 to 5 As shown, this embodiment provides a lower sealing element 1 for a sliding door hook with drainage function, including a sealing body 11 and a drain pipe 12; the sealing body 11 has a drainage cavity 111; the drainage cavity 111 forms an inlet 112 on the top surface of the sealing body 11 and a drain outlet 113 on the left and / or right side of the sealing body 11; the drain pipe 12 has a drainage channel 121; one end of the drain pipe 12 is connected to the drain outlet 113 of the sealing body 11, and the drainage channel 121 of the drain pipe 12 communicates with the drainage cavity 111 of the sealing body 11; a drainage hole 122 communicating with the drainage channel 121 is provided on the bottom side of the drain pipe 12.
[0026] Please refer to the following: Figure 1 As shown, the top side of the sealing body 11 has a groove 114; the water inlet 112 is located at the bottom of the groove 114. In this embodiment, the groove is designed to have a certain water storage capacity, so that when water passes through the top surface of the sealing body, the groove can guide the water into the drainage chamber.
[0027] Please refer to the following: Figure 2 As shown, the sealing body 11 has drain ports 113 on both its left and right sides; the drain pipe 12 is connected to one of the drain ports 113, and the other drain port 113 is connected to a plug 13. In this embodiment, the drain pipe can be connected to the corresponding drain port according to the actual installation situation, while the drain port on the other side that is not needed is sealed with a plug.
[0028] Please refer to Figures 6 to 8As shown, this embodiment also provides a sliding door, including a sliding door track 2, which has an outdoor track 21 and an indoor track 22; a first sliding door hook 3 is installed on the outdoor track 21, and a second sliding door hook 4 is installed on the indoor track 22; a track gap 23 is formed between the outdoor track 21 and the indoor track 22; a sealing member 1 is installed in the track gap 23, and the left and right sides of the sealing member 1 are sealed to the outdoor track 21 and the indoor track 22 respectively; the top side of the sealing member 1 is sealed to the bottom side of the first sliding door hook 3 and the second sliding door hook 4.
[0029] Please refer to the following: Figure 8 As shown, the outdoor track 21 has a through hole; the drain pipe 12 of the sealing element 1 passes through the through hole of the outdoor track 21, so that the drain hole 122 is located on the outdoor side. The drain pipe can drain water to the outdoor side.
[0030] Please refer to the following: Figure 6 and Figure 7 As shown, the seal 1 is installed on the track seam 23 and located in the area below the overlap of the first sliding door hook sash 3 and the second sliding door hook sash 4. In this embodiment, the seal 1 can effectively isolate the indoor and outdoor sides of the track seam, preventing water from flowing from the outdoor side of the track seam to the indoor side.
[0031] Please refer to the following: Figure 6 and Figure 7 As shown, the water inlet of the seal 1 is exposed on the indoor side; in this embodiment, the top surface of the seal 1 is lower than the top surface of the indoor track 22; this can effectively drain rainwater from the indoor side.
[0032] In this embodiment, the sealing element is installed at the track seam below the overlapping area of the two sliding door hooks. The position of the sealing element is adjusted so that the water inlet on the sealing element is exposed on the indoor side. A drain pipe is inserted through the through hole in the outdoor track, so that the drain pipe is inserted into the drain outlet of the sealing element. When rainwater enters the indoor side from the gap between the two sliding door hooks, the rainwater will flow into the drain pipe through the water inlet, drainage chamber, and drain outlet of the sealing element, and then flow to the outdoor side through the drainage channel and drainage hole of the drain pipe. The drain hole of the drain pipe is located on the bottom side, not directly facing the wind pressure, so that the rainwater can be smoothly discharged to the outdoor side.
[0033] In this implementation, the sealing element not only seals but also has windproof and drainage functions. It can work in conjunction with other drainage holes of the sliding door (not shown in the attached diagram) to achieve rapid drainage, thereby improving the sealing and waterproofing effect of the sliding door.
[0034] The above embodiments should not limit the present invention in any way. All technical solutions obtained by equivalent substitution or equivalent conversion fall within the protection scope of the present invention.
