Nail column and edge-cladding glass assembly with nail column

Abstract

The invention belongs to the technical field of car window glass accessories, and particularly relates to a nail column used for positioning and fixing car window glass. The nail column comprises a base and a column body and is characterized in that a clamping groove used for clamping of a positioning base is formed in the upper surface of a base, a chock block is arranged on the upper portion ofthe inner side wall of the clamping groove, the bottom face of the clamping groove is provided with a center boss attached to the bottom face of the positioning base and an annular guide groove formedin the periphery of the center boss, a guide protrusion is arranged on the lower portion of the outer side wall of the positioning base, a positioning protrusion is arranged on the rear end of the upper surface of the guide protrusion which can slide along the annular guide groove, a rotation stop face is arranged on the side, facing the positioning protrusion of the chock block, the rotation stop face of the chock block is matched with the front side face, facing the chock block, of the positioning protrusion, and the lower surface of the chock block is matched with the upper surface of theguide protrusion, and is used for limiting axial moving of the column body. Meanwhile, the invention further provides the edge-cladding glass assembly with the nail column. The advantage that after splitting, the assembling structure is simple, compact, good in stability and high in fit precision is achieved.

Description

Technical field: [0001] The invention belongs to the technical field of vehicle window glass fittings, in particular to a nail post for positioning and fixing a vehicle window glass and an edge-wrapped glass assembly equipped with the nail post. Background technique: [0002] At present, the window glass of the car is mainly positioned precisely by the studs to the corresponding joints of the car body and ensures long-lasting reliability. The existing nail post is mainly composed of a base and a post body, and the post body is also provided with elastic claws. When installing the window glass, first fix the base of the nail post on the window glass, and then insert the post of the nail post into the mounting hole on the body sheet metal. During this process, the elastic claws are squeezed by the edge of the mounting hole of the sheet metal, resulting in radial elastic shrinkage deformation. The edge of the hole is detached, so that the elastic force of the elastic claw can...

Problems solved by technology

However, this structure has no axial locking structure, and the pin can rotate. If the pin rotates during pre-installation, especially when it matches the oblong hole, it will cause the pin to come out of the oblong hole and cause the product to fall off.

In addition, the matching accuracy of this clamping structure is not high, resulting in low positioning accuracy of the window glass on the automobile body sheet metal
