Description

Insert assembly of automobile door frame sealing strip

Technical Field

The utility model belongs to the technical field of automobile parts and relates to an insert assembly of an automobile door frame sealing strip.

Background

The automobile door frame sealing strip is a sealing part arranged between a door frame metal plate and an automobile body side wall, and is used for realizing sealing and dust separation of an automobile and shielding door welding beading or coating adhesive scars and the like. The automobile door frame sealing strip includes the sealing strip sash section, sealing strip hypomere and sealing strip connect the angle, wherein, the sealing strip connects the angle and indicates the position that the sealing strip structure changes, the sealing strip connects the angle to include the sealing strip and connects the angle body, connect the angle insert (set up and improve its rigidity on the sealing strip connects the angle body) and connect the angle buckle (connect the angle body in order to realize the sealing strip and connect the being connected of angle body sealing strip and door frame panel beating), current sealing strip connects the angle body, connect the angle insert and connect the angle buckle and generally adopt integrative injection moulding, but this kind of structure has following shortcoming: the corner connecting buckle connected with the automobile door frame metal plate is a quick-wear part, and once the corner connecting buckle is damaged, the whole automobile door frame sealing strip needs to be replaced, so that the cost is high, and the waste of the replaced sealing strip is also caused.

In order to solve the problem, the chinese patent document discloses a weather strip insert, an automotive weather strip and an automobile (application number: 201620434417.3), the automotive weather strip includes a weather strip insert, a clip and a weather strip body, the weather strip insert includes a weather strip insert body; a first groove is formed in the side face of the sealing strip insert body, and a limiting hole communicated with the first groove is formed in the groove wall of the top face of the first groove; the limiting opening end of the limiting hole penetrates through the side face of the sealing strip insert body; the limiting hole allows a clamp to enter the limiting hole along the limiting opening end of the limiting hole, the top groove wall of the first groove can be clamped with the circular base of the clamp, the clamp is connected with the sealing strip insert in a detachable mode, and the sealing strip connecting angle of the sealing strip body is connected with the sealing strip insert. Although this automobile sealing strip has been solved and has been damaged the back in connecing the angle buckle, has avoided the change of whole root car door frame sealing strip and has produced extravagantly, has brought new problem again: when using, because this automobile sealing strip's checkpost need enter first circular arc hole along the flaring mouth, again with the checkpost joint to the door on, so need reserve great opening to because this opening will be used for stretching into and taking out of checkpost, so this opening can not be wrapped up by the sealing strip body and lead to the sealing strip insert body to have large tracts of land direct contact with door frame panel beating, thereby cause the abnormal sound.

Disclosure of Invention

The utility model aims to solve the problems in the prior art and provides an insert assembly of an automobile door frame sealing strip. The technical problem to be solved by the utility model is how to avoid waste caused by replacing the whole automobile door frame sealing strip and reduce abnormal sound after the corner connecting buckle is damaged.

The purpose of the utility model can be realized by the following technical scheme: the utility model provides an insert subassembly of car door frame sealing strip, includes that the sealing strip connects the angle body, connects the angle mold insert and connects the angle buckle, its characterized in that, offer the installation cavity that is used for setting up the angle mold insert on the sealing strip connects the angle body, connect the angle buckle to include the buckle body, the symmetry is provided with at least a pair of elasticity card arm on the buckle body, and every all has the elasticity clearance between every pair of elasticity card arm, set up the opening that supplies elasticity card arm to stretch into or take out on the installation cavity, connect and offer the mounting hole that is used for dismantling the connection with elasticity card arm corresponding open-ended position on the angle mold insert.
