Description

Sealing strip anti-channeling structure

Technical Field

The utility model relates to a skylight structure, the structure is prevented scurrying by sealing strip specifically says so.

Background

With the development of the existing automobile industry, more and more automobiles are provided with skylights in an improved configuration, competition among all skylight suppliers is more and more intense, and the quality of the skylights needs to be improved to obtain a hidden point which can avoid problems as much as possible. The periphery of the existing rear skylight glass adopts a structure that PU adds sealing strips, but because the operation of a mechanical group can generate friction interference with side sealing strips and because of the length of the sealing strip assembly, the material causes the front and back movement of the sealing strip assembly, the sealing strips can generate gaps with PU, the risk of skylight water inflow is increased, and the safety and stability use performance of the skylight is influenced.

Disclosure of Invention

The utility model provides a simple structure can effective spacing side sealing strip, prevents to receive the sealing strip anti-channeling structure that mechanical group friction drunkenness influences sealing performance.

The utility model adopts the technical proposal that: the utility model provides a structure is scurried in skylight sealing strip prevents scurring which characterized in that: including setting up in the PU of skylight side fore-and-aft direction bordure and install the sealing strip that the PU bordures, PU bordures the installation trench that sets up the fore-and-aft direction, and installation trench tank bottom sets up interior draw-in groove, and the sealing strip rear side sets up the dop muscle of draw-in groove in the joint, sets up the spacing draw-in groove of more than one perpendicular to fore-and-aft direction and/or the spacing boss of more than one perpendicular to fore-and-aft direction on the interior draw-in groove, sets up the dop boss that corresponds spacing draw-in groove and/or the dop draw-in groove that corresponds spacing boss on the dop muscle.

Furthermore, the front end and the rear end of the installation slot are provided with terminal struts in the front-rear direction towards the inner side of the inner slot, the front side of the sealing strip is provided with a hollow cavity structure, and the front end and the rear end of the hollow cavity structure are respectively clamped with the terminal struts in the front and the rear of the installation slot.

Furthermore, the inner clamping groove and the clamping head rib adopt a dovetail clamping structure.

Further, the chuck rib is hollow in the length direction.

Furthermore, the hollow section of the chuck rib is square.

Furthermore, the cross section of the limiting clamping groove is of an outward-expanding and sinking structure corresponding to the cross section of the clamping groove.

Furthermore, the limiting boss is arranged at the bottom of the inner clamping groove.

The utility model discloses bordure through it and PU with the drunkenness around the sealing strip and mate dop boss joint through a plurality of independent or the spacing draw-in groove of mixing use spacing, prevent that the sealing strip from receiving the mechanical group friction and leading to throw off or the drunkenness, effectively ensure its stability of service performance, combine the hollow cavity cross-under end pillar direction of sealing strip front and back footpath, further improve its installation and stably prevent scurrying the performance.

Detailed Description

The following is further described with reference to the accompanying drawings.

FIGS. 1-5 show: the utility model provides a skylight sealing strip anti-channeling structure, includes the PU bordure 3 that sets up in 2 side front and back directions in skylight glass, PU bordure through dovetail joint structure joint sealing strip 9, sealing strip 9 corresponds mechanical group 1. In fig. 2-4, the PU covering edge is provided with a mounting groove position 4 in the front-back direction, an inner clamping groove 5 is arranged at the bottom of the mounting groove position 4, a clamping head rib 11 clamped with the inner clamping groove 5 is arranged at the rear side of a sealing strip 9, a limiting clamping groove 6 is arranged at one end of the inner clamping groove 5, a limiting boss 7 is arranged at the other end of the inner clamping groove 5, and a clamping head boss 12 corresponding to the limiting clamping groove and a clamping head clamping groove mounting 13 corresponding to the limiting boss are arranged at two ends of the clamping head rib 11; the front end and the rear end of the mounting groove position 4 are provided with terminal struts 8 in the front-rear direction towards the inner side of the inner clamping groove, the front side of the sealing strip is provided with a hollow cavity structure 10, and the front end and the rear end of the hollow cavity structure are respectively clamped with the terminal struts in the front and the rear of the mounting groove position.

On the basis of this embodiment, can design dop muscle hollow cross-section for square.

On the basis of this embodiment, can design spacing draw-in groove cross-section and expand outward, sink the structure for interior corresponding draw-in groove cross-section, the cooperation chucking is more stable.

On the basis of this embodiment, can design including the setting of spacing boss draw-in groove tank bottom, the cooperation chucking is more stable.
