The utility model relates to a fastener for connecting a rainwater groove and the sheet metal of a vehicle door, which comprises a main body and elastic clamps which are positioned on both ends of the main body, wherein a protrusion which extends outwards is arranged on the upper surface of the middle part of the main body. The utility model is characterized in that the protrusion presents a conical shape, an annular clamping groove is arranged on the circumferential surface of the bottom of the conical protrusion and openings are arranged on the circumferential surface of the protrusion on the clamping groove to form two independent elastic wall surfaces. A pressing block for increasing friction can be arranged on the lower surface of the middle part of the main body, and a chock block can also be arranged on the lower surface of the middle part of the main body. Because the protrusion adopts a cone with solid structure, the intensity of the protrusion can be increased, and simultaneously, the protrusion can be easily inserted into a through hole; the elasticity of each of the elastic wall surfaces which are formed on both sides of the protrusion is good because the thickness of each wall is correspondingly thin, and the elastic wall surfaces can be firmer after connected. Secondly, a presser foot can be arranged on the lower surface of the middle part of the main body to cause the utility model to be not easy to break to cause use to be more reliable. In addition, the chock block is matched with a notch on the corresponding point of the rainwater groove to thoroughly prevent the fastener from moving. Thus, the utility model can better satisfy use requirements and is worthy of being popularized and used on vehicles.

Summary of the invention

Technical problem to be solved in the utility model 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 utility model 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, advantage of the present utility model is: 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 utility model more can satisfy the requirement in the use, is worth applying on vehicle.
