Problems solved by technology

[0003] The existing car chassis guard plate installation structure mainly has the following defects: First, the nut and the chassis guard plate are separate structures, which need to be purchased separately and assembled on the car assembly line, which increases the cost of parts and assembly man-hours Second, the automobile assembly line requires a multi-step installation process, including first pre-installing the chassis guard plate on the body, and then using a torque gun to tighten and fix the nuts and welding studs; third, the structural chassis sheet metal after installation In contact with the guard plate, there will be friction between the chassis sheet metal and the guard plate during the operation of the vehicle, which will damage the protection of the sheet metal surface and easily lead to the risk of sheet metal corrosion

Embodiment 1

[0039] Such as figure 1 and figure 2 The shown detachable chassis guard nut includes a cylinder 1, an umbrella-shaped limit cover 2, a spring foot 3 and a clamp foot 4, and the nut is an integral injection molding structure made of plastic.

[0040] The column body 1 has a columnar frame structure as a whole. The column body 1 includes a bottom frame 1-1 and a column frame 1-2. The bottom frame 1-1 is located at the bottom of the column frame 1-2 and the column frames 1-2 are evenly spaced along the circumferential direction. . Umbrella-shaped stop cover 2 is positioned at the top of column body 1, and the position corresponding to the central axis of column body 1 on bottom frame 1-1 and umbrella-shaped stop cover 2 is provided with through hole, makes umbrella-shaped stop cover 2 and column body 1 The direction along the central axis is a through structure. An inner hexagonal structure 8 is arranged in the middle of the top of the umbrella-shaped stop cover 2 for connect...

Abstract

The invention relates to a detachable chassis guard plate nut which comprises a column body, an umbrella-shaped limiting cover, elastic feet and clamping feet, the umbrella-shaped limiting cover is located at the top of the column body, the umbrella-shaped limiting cover and the column body are of a through structure in the central axis direction of the column body, and the elastic feet are evenlydistributed on the outer side of the column body at intervals in the circumferential direction; the lower ends of the elastic feet are fixed to the column body, the upper ends of the elastic feet areof movable structures capable of being compressed inwards, limiting protruding shoulders are arranged on the elastic feet, the clamping feet are evenly distributed on the inner side of the column body in the circumferential direction at intervals, and the inner side faces of the multiple clamping feet distributed in the circumferential direction face the central axis of the column body and are provided with matched thread structures. The nut and a protective plate can be integrated and preassembled, the protective plate and the automobile chassis metal plate can be conveniently assembled anddisassembled, the cost can be reduced, the assembling efficiency can be improved, and friction between the protective plate and the chassis metal plate can be avoided.

Description

technical field [0001] The invention belongs to the technical field of automobile chassis guard plate installation, in particular to a detachable chassis guard plate nut. Background technique [0002] The exterior chassis guards of various cars need to be installed on the sheet metal of the car body chassis through connectors. The existing car chassis guard installation structure is to weld an iron stud on the body chassis sheet metal. When the bottom guard plate After the holes on the top pass through the studs, use a torque gun to tighten the fixing nuts to the studs to complete the installation of the bottom guard. [0003] The existing car chassis guard plate installation structure mainly has the following defects: First, the nut and the chassis guard plate are separate structures, which need to be purchased separately and assembled on the car assembly line, which increases the cost of parts and assembly man-hours Second, the automobile assembly line requires a multi-st...
