Summary of the invention

Technical problem to be solved by this invention is the defective that overcomes prior art, provide a kind of intensity good and easily assembling be used for buckle that gutter is connected with the car door panel beating.

The present invention solves the problems of the technologies described above the technological scheme that is adopted: this is used for the buckle that gutter is connected with the car door panel beating is comprised main body and the resilient clip that is positioned at the two ends of main body, described main body middle part upper surface is provided with outward extending projection, it is characterized in that: described projection is coniform, on the side face of the bottom of this cone-shaped bulge, be provided with annular slot, and the protruding side face upper shed on this draw-in groove and form two elasticity walls independently.

Can be provided with the briquetting that is used for increasing frictional force on the lower surface of described main body middle part.

Also can be provided with block on the lower surface of described main body middle part, the breach in this block and the gutter matches, and is buckled in laterally moving in the gutter to stop up hill and dale.

Described two elasticity walls are to be circumferentially uniform for good, and are more reliable after feasible the connection.

Compared with prior art, the invention has the advantages that: because projection adopts the cone of solid construction, this is when increasing protruding intensity, also make projection be easier to insert in the through hole, and the elasticity wall that its both sides forms is thinner relatively because of wall thickness, thereby elasticity is better, and is more firm after the connection.Secondly presser feet is arranged on the lower surface at main body middle part, frangibility is not used more reliable.Moreover the block that on the main body lower surface, is provided with, the breach of itself and gutter corresponding part matches, and can stop moving of buckle up hill and dale.Therefore the present invention more can satisfy the requirement in the use, is worth applying on vehicle.
