Description

Technical Field

[0001] The utility model relates to the technical field of sliding door components, in particular to a sliding door hook upper end sealing component with fast clamping, double-layer and long-term sealing function. Background Art

[0002] Lifting sliding door is different from ordinary sliding door and heavy sliding door. Lifting sliding door is used on relatively large and heavy sliding door. The difference from ordinary sliding door is the hardware used in the lifting system, such as lifting handle, transmission, connecting rod, which are not needed for ordinary sliding door. Simply put, its principle is the lever principle. After the lifting handle is closed, the pulley is lifted up, and the sliding door cannot be moved anymore, which enhances safety and prolongs the service life of the pulley.

[0003] With the current lifting and sliding doors, since the upper frame of the sliding door is fixedly assembled, the sealing on the upper side of the sliding door is poor during the lifting process, and the sliding door and its upper frame are sealed only by sponge. When the sliding door is in the lifted state, the sponge is completely compressed. When the sliding door is in the closed state, the sliding door descends, and the sliding door and its upper frame are sealed by the completely resilient sponge. During long-term use, the sponge is continuously compressed and its rebound ability gradually decreases, resulting in a decrease in the sealing ability between the sliding door and its upper frame, affecting the user experience and sealing effect of the lifting and sliding door.

[0043] In a further embodiment of the utility model, a sponge sealing structure and a wool strip sealing structure are installed on the support cover 12, and the upper end of the hook of the sliding door 2 and the upper frame of the sliding door are sealed by the sponge sealing structure and the wool strip sealing structure.

[0044] In a further embodiment of the present invention, the sponge sealing structure is composed of a high-elastic sponge 13 and a high-elastic plastic sheet 14. Figure 6As shown, during the rising process of the lifting and sliding door, the high-elastic sponge 13 will be compressed to the lowest level. When the lifting and sliding door is in the closed state, the lifting and sliding door will drop, and the high-elastic sponge 13 will bounce up completely, sealing the upper end of the hook of the sliding door 2 and the upper frame of the sliding door.

[0045] In a further embodiment of the present invention, the wool strip sealing structure is composed of a movable plate device 15, a sealing wool strip 16, a spring 17 and a telescopic shaft 19. Figure 6 As shown, the movable plate device 15 is clamped in the wool strip sealing structure installation groove of the support cover 12 and can be displaced in the vertical direction. One end of the telescopic shaft portion 19 is connected to the bottom of the movable plate device 15, and the other end of the telescopic shaft portion 19 is connected to the groove bottom of the wool strip sealing structure installation groove. The telescopic shaft portion 19 is composed of a shaft portion and a shaft sleeve, and the shaft portion can slide in the shaft sleeve. The movable plate device 15 is displaced in the vertical direction in the wool strip sealing structure installation groove through the telescopic shaft portion 19. The notch of the wool strip sealing structure installation groove is provided with an annular limiting structure, and the outer periphery of the bottom of the movable plate device 15 is provided with an annular protrusion. The spring 17 is sleeved on the telescopic shaft portion 19, and one end of the spring 17 is against the bottom of the movable plate device 15, and the other end of the spring 17 is against the wool strip sealing structure. The bottom of the groove of the strip sealing structure installation groove is formed by the spring 17, and the movable plate device 15 is completely bounced up under the action of the spring 17. The upper surface of the annular protrusion of the movable plate device 15 is against the lower surface of the annular limiting structure of the strip sealing structure installation groove to prevent the movable plate device 15 from detaching from the strip sealing structure installation groove. Under the action of the spring 17, the movable plate device 15 has good resilience. The sealing strip 16 is pushed into the top slide groove of the movable plate device 15 from one side. When the lifting and sliding door is in the rising process, the movable plate device 15 moves downward, and the spring 17 will be compressed to the lowest point. When the lifting and sliding door is in the closed state, the lifting and sliding door descends, and the spring 17 will be completely bounced up, and the upper end of the hook of the sliding door 2 and the upper frame of the sliding door are sealed through the sealing strip 16.

[0046] In a further embodiment of the utility model, the structure of the sealing component body 1 is simple and easy to assemble. The support cover base 11 is pushed into the upper end of the hook of the sliding door 2, and the limiting structure plate of the support cover base 11 is against the sliding door 2 and locked by screws. The top of the support cover 12 is provided with a sponge sealing structure installation groove and a wool strip sealing structure installation groove. The high-elastic plastic sheet 14 is folded and inserted into the cavity of the high-elastic sponge 13, and then the high-elastic sponge 13 is inserted into the sponge sealing structure installation groove. The shaft sleeve end of the telescopic shaft portion 19 is connected to the groove bottom of the wool strip sealing structure installation groove, and the shaft end of the telescopic shaft portion 19 is provided with a gasket matching the bottom groove of the movable plate device 15. After the spring 17 is sleeved on the telescopic shaft portion 19, the movable plate device 15 is pressed downward, so that the annular protrusion of the movable plate device 15 is stuck in the annular limiting structure of the wool strip sealing structure installation groove. The top inner edge of the annular limiting structure is provided with an oblique angle, and the bottom outer edge of the annular protrusion is provided with an oblique angle, such as Figure 6 As shown, it is convenient to press the movable plate device 15 into the installation groove of the wool strip sealing structure, and the annular protrusion is limited by the annular limiting structure to prevent the movable plate device 15 from popping out of the installation groove of the wool strip sealing structure. A sliding groove is provided on the top of the movable plate device 15, and the sealing wool strip 16 is pushed into the top sliding groove of the movable plate device 15 from one side. The support cover 12 is inserted into the support cover installation groove in the horizontal direction and rests on the bottom of the support cover installation groove. The decorative cover plate 18 is pushed upward from the side of the sliding door 2 to block the multiple assembly holes of the support cover base 11, and at the same time limit the support cover 12 to prevent the support cover 12 from sliding out of the support cover installation groove.

[0047] In a further embodiment of the utility model, the decorative cover plate 18 is pushed upward from the side of the sliding door 2, and the decorative cover plate 18 limits the support cover 12 to prevent the support cover 12 from sliding out of the support cover base 11 during the opening and closing process of the lifting sliding door.

The insertion directions of the high-elastic plastic sheet 14 and the sealing wool strip 16 are perpendicular to the opening and closing directions of the lifting sliding door. The assembly process of the sealing component main body 1 is simple, and the high-elastic plastic sheet 14 and the sealing wool strip 16 will not slip or fall off due to repeated opening and closing of the sliding door.

[0049] In a further embodiment of the utility model, the high-elastic plastic sheet 14 is made of PE material, has high resilience and service life, and adopts an inverted "M" structure, which effectively improves the resilience performance of the high-elastic sponge 13.

[0050] In a further embodiment of the utility model, the upper surface of the high-elastic sponge 13 is wavy in shape, which reduces the contact area between the high-elastic sponge 13 and the upper frame of the sliding door during the opening and closing process of the lifting sliding door, reduces the friction, and at the same time increases the deformation of the high-elastic sponge 13 and improves the sealing effect of the high-elastic sponge 13.
