Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be further described below.

As shown in fig. 1 and fig. 2, the utility model provides a waterproof connection buckle for vehicle, which comprises a sub-part bolt 1 and a connection fixing seat 2; the end part of the connecting and fixing seat 2 is provided with a slot 21 for inserting the sub-part plug pin 1, and the bottom of the connecting and fixing seat 2 is provided with a plug 22 for inserting the automobile body metal plate 3; the end part of the sub-part bolt 1 is provided with a mounting groove 11 for clamping with the vehicle body protection plate 4, and a pin head 12 of the sub-part bolt 1 is inserted into a slot 21 of the connecting fixing seat 2.

In this embodiment, as shown in fig. 4, the end of the connecting fixing base 2 is a baffle 23, and a waterproof sealing ring 5 is fixed on one side of the baffle 23 facing the plug 22; waterproof sealing ring 5 is equipped with the shirt rim that the round and 3 sealed of automobile body panel beating, can effectually prevent the waterproof sealing effect of panel beating installation department, avoids intaking in the car and causes the damage of circuit, has also played the effect of pretension simultaneously, avoids producing the abnormal sound because of the vibration of automobile body. And the sealing ring 5 is formed by performing secondary injection molding on elastomer raw materials such as TPE (thermoplastic elastomer), TPV (thermoplastic vulcanizate) and the like on the base body of the fixing seat.

In the embodiment, the plug 22 includes two oppositely arranged oblique guiding spring feet 24, and the end parts of the two spring feet 24 are in an inward-contracting and inverted-buckling structure; as shown in fig. 5 and 6, when the automobile body metal plate 3 is connected, the plug 22 is inserted into a mounting hole pre-opened on the automobile body metal plate 3, and then the automobile body metal plate 3 is fixed between the baffle 23 and the elastic foot 24 through the two elastic feet 24, and the inward-retraction inverted buckle structure at the end part of the elastic foot 24 can ensure the pull-out force between the automobile body metal plate and the metal plate.
