Description

Technical Field

[0001] This utility model relates to the field of vehicle sliding window technology, and in particular to a flush sliding window with a drainage structure. Background Technology

[0002] Flush sliding windows are widely used in rail transit, commercial vehicles, high-end buildings and other fields due to their flat appearance, good sealing and low wind resistance. They use guide rails and sliding mechanisms to achieve the sliding function, and the internal spring and pull rope system allows the movable window sash to be flush with the fixed window sash when closed, providing good dustproof, waterproof and soundproof performance.

[0003] In actual use, due to the assembly gap between the movable window frame and the guide rail, a small amount of water may seep into the lower guide rail and be discharged through the pre-set drainage groove inside the guide rail. Since the water contains a certain amount of dust and impurities, it is easy to cause the drainage groove inside the guide rail to become blocked during long-term use, affecting normal drainage and making cleaning difficult.

[0004] Therefore, to address the aforementioned issues, a flush-mounted sliding window with a drainage structure can be designed. By adding an integrated drainage box with an air inlet below the drainage channel, when the drainage channel becomes clogged due to dust and impurities, a conventional air inlet device can be connected via the air inlet connector to inject high-speed airflow into the drainage box and drainage channel. The impact effect of the airflow is used to quickly clear the blockage, effectively solving the problem of difficult maintenance of traditional drainage structures and improving the convenience and reliability of the equipment. Utility Model Content

[0005] To overcome the assembly gap between the movable window frame and the guide rail, a small amount of water may seep into the lower guide rail and be discharged through the pre-set drainage groove inside the guide rail. However, since the water contains certain dust and impurities, it is easy to cause blockage of the drainage groove inside the guide rail during long-term use, affecting normal drainage and making cleaning difficult.

[0006] The technical solution of this utility model is as follows: a flush sliding window with a drainage structure, including a fixed window and a movable window. An upper guide rail and a lower guide rail are fixedly installed on one side of the fixed window. Sealing strips are provided on the contact surfaces of the upper guide rail, the lower guide rail and the fixed window. A drainage groove is opened inside the lower guide rail. The sealing strip inside the lower guide rail has a segmented structure, which, together with the drainage groove, forms a through drainage channel. A drainage box is fixedly installed at the lower end of the lower guide rail. The interior of the drainage box is connected to the drainage groove. A connecting pipe is connected through one side of the drainage box. An air nozzle connector is fixedly installed at one end of the connecting pipe.

[0007] Preferably, sealing strips are used to ensure the sealing between the upper and lower guide rails and the fixed window. A drainage channel is provided to guide any small amount of water that seeps in to the drainage box, and then drain it out of the vehicle. A connecting pipe is used to install the air nozzle connector. When the drainage channel becomes clogged, a conventional inflation device can be connected through the air nozzle connector to inject high-speed airflow into the drainage box and drainage channel, using the impact effect of the airflow to quickly clear the blockage.

[0008] Preferably, the upper edge of the lower guide rail that contacts the fixed window has a beveled structure.

[0009] Preferably, one side of the sealing strip has a multi-set helical tooth structure, and the sides of the upper and lower guide rails corresponding to the sealing strip also have corresponding helical tooth structures.

[0010] Preferably, two sets of sliding connectors are fixedly installed around the perimeter of the movable window, and the two sets of sliding connectors are slidably connected to the upper guide rail and the lower guide rail respectively.

[0011] Preferably, each sliding connector is equipped with a spring and sliding gear mechanism for pressing the movable window. The springs and sliding gear mechanisms in the two sets of sliding connectors are connected by a steel wire rope to operate synchronously. The sliding connector that is slidably connected to the lower guide rail is equipped with a handle to control the spring and sliding gear mechanism.

[0012] Preferably, both the upper and lower guide rails have multiple sets of square teeth inside.

[0013] The beneficial effects of this utility model are:

[0014] The sloping upper edge of the lower guide rail guides a small amount of seeping water into the drainage channel and eventually into the drainage box, from where it is discharged outside the vehicle. The internal space of the drainage box provides a large temporary storage space for water, reducing the probability of dust clogging the narrow drainage channel. When blockage occurs due to the accumulation of dust and impurities after long-term use, a conventional air inflation device is connected via an air nozzle connector to inject high-speed airflow into the drainage box and drainage channel. The impact effect of the airflow quickly clears the blockage without the need for disassembly, resulting in high efficiency and low cost. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 , Figure 3 and Figure 5 This utility model provides an embodiment: a flush sliding window with a drainage structure, including a fixed window 1 and a movable window 2. An upper guide rail 3 and a lower guide rail 4 are fixedly installed on one side of the fixed window 1. Sealing strips 6 are provided on the contact surfaces of the upper guide rail 3, the lower guide rail 4, and the fixed window 1. A drainage groove 7 is provided inside the lower guide rail 4. The sealing strip 6 inside the lower guide rail 4 has a segmented structure, forming a through drainage channel with the drainage groove 7. A drainage box 8 is fixedly installed at the lower end of the lower guide rail 4. The interior of the drainage box 8 communicates with the drainage groove 7, and a connecting pipe 801 is connected through one side of the drainage box 8. One end of the connecting pipe 801 is fixedly installed with an air nozzle connector 802; the sealing strip 6 is set to achieve the installation seal between the upper guide rail 3 and the lower guide rail 4 and the fixed window 1; the drainage groove 7 is set to guide a small amount of seeping water to drain into the drainage box 8 and then drain it out of the vehicle through the drainage box 8; the air nozzle connector 802 is installed through the connecting pipe 801; when the drainage groove 7 is blocked, a conventional air inflation device can be connected through the air nozzle connector 802 to inject high-speed airflow into the drainage box 8 and the drainage groove 7, and the impact effect of the airflow can be used to quickly clear the blockage.

[0023] Please see Figure 3 and Figure 4In this embodiment, the upper edge of the lower guide rail 4 that contacts the fixed window 1 is a beveled structure. By setting the beveled structure, water can be guided to smoothly enter the drainage groove 7. One side of the sealing strip 6 has multiple sets of beveled teeth. The upper guide rail 3 and the lower guide rail 4 corresponding to the sealing strip 6 are also provided with corresponding beveled teeth. By setting the beveled teeth, the biting force and stability between the sealing strip 6 and the upper guide rail 3 and the lower guide rail 4 can be guaranteed, and a multi-layer sealing effect can be constructed to prevent water from entering the vehicle. Two sets of sliding connectors 201 are fixedly installed on the periphery of the movable window 2. The two sets of sliding connectors 201 are slidably connected to the upper guide rail 3 and the lower guide rail 4 respectively.

[0024] Please see Figure 1 and Figure 2 In this embodiment, the sliding connector 201 is equipped with a spring and a sliding gear mechanism for pressing the movable window 2. The springs and sliding gear mechanisms in the two sets of sliding connectors 201 are connected by a steel wire rope and move synchronously. The sliding connector 201 slidably connected to the lower guide rail 4 is equipped with a handle 202 for controlling the spring and sliding gear mechanism. The upper guide rail 3 and the lower guide rail 4 are equipped with multiple sets of square teeth 5. By setting the square teeth 5, the sliding connector 201 can stop at any position on the upper guide rail 3 and the lower guide rail 4.

[0025] During operation, the sliding connector 201 is used to connect the movable window 2 with the upper guide rail 3 and the lower guide rail 4, thereby enabling the normal opening and closing of the movable window 2. Both sets of sliding connectors 201 are equipped with springs and sliding gear mechanisms for pressing the movable window 2. The springs and sliding gear mechanisms in the two sets of sliding connectors 201 are connected by steel wire ropes and move synchronously, and are controlled by handle 202, so that the movable window 2 can be kept flush with the fixed window 1 when closed.

[0026] The inclined structure of the upper edge of the lower guide rail 4 can guide a small amount of seeping water into the drainage channel 7 and finally discharge it into the drainage box 8. The water is then discharged to the outside of the vehicle through the drainage box 8. The internal space of the drainage box 8 can provide a large temporary storage space for water, reducing the probability of dust clogging the narrow drainage channel 7.

[0027] When blockages occur due to dust and impurities after long-term use, a conventional air inflation device can be connected using the air nozzle connector 802 to inject high-speed airflow into the drain box 8 and drain trough 7. The impact effect of the airflow is used to quickly clear the blockages without disassembly, which is highly efficient and low-cost.

[0028] Through the above steps, the drainage channel 7 can guide a small amount of seeping water to the drainage box 8, and then discharge it to the outside of the vehicle through the drainage box 8. When the drainage channel 7 becomes blocked, a conventional air inflation device can be connected through the air nozzle connector 802 to inject high-speed airflow into the drainage box 8 and the drainage channel 7. The impact effect of the airflow is used to quickly clear the blockage. This solves the problem that there is an assembly gap between the movable window frame and the guide rail, and a small amount of water may seep into the lower guide rail. As the water is discharged through the pre-set drainage channel 7 in the guide rail, the water contains certain dust and impurities, which can easily cause the drainage channel 7 in the guide rail to become blocked during long-term use, affecting normal drainage and making cleaning difficult.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
