Abstract
The utility model discloses the T-shaped welded nut of a kind of automobile, the annulus that comprises T-shaped nut body and be connected as a single entity with T-shaped nut body, described T-shaped nut upper end is round structure, in the middle of round structure, be provided with radial screw bore, described T-shaped nut body and parts face of weld are provided with three square cambered surface projections, described three square cambered surface projections are arranged and are equilateral triangle shape, described tapped hole and face of weld intersection are provided with protruding ring, described protruding ring height is greater than the height of three square cambered surface projections, described annulus edge is rounded feature, adopt design proposal of the present utility model, at the face of weld of T-shaped nut, three square cambered surface projections and protruding ring are rationally set, when welding, T-shaped welded nut is close to parts, only have the annular projection of T-shaped welded nut to contact with parts with square cambered surface projection, after welding, just can guarantee quality and the intensity of welding.The utlity model has that welding quality is good, the high advantage of weld strength.
Description
Technical field
The utility model belongs to field of mechanical technique, is specifically related to the T-shaped welded nut of a kind of automobile.
Background technique
Some Switch for door and window parts are installed in the inner side of vehicle door, the common screw-thread securing of these Switch for door and window parts is on welded nut (comprising T type welded nut), then the outside end face of welded nut and vehicle door steel plate carry out pressure welding welding, but because be that the whole outside end face of welded nut contacts with car door steel plate, often produce that pressure welding welding quality is poor, the not high deficiency of weld strength.
Summary of the invention
The purpose of this utility model is to design the T-shaped welded nut of a kind of automobile.
The problem that to be solved in the utility model is existing welded nut poor welding quality, weld strength is not high.
The technical solution of the utility model is: the annulus that comprises T-shaped nut body and be connected as a single entity with T-shaped nut body, described T-shaped nut upper end is round structure, in the middle of round structure, be provided with radial screw bore, described T-shaped nut body and parts face of weld are provided with three square cambered surface projections, described three square cambered surface projections are arranged and are equilateral triangle shape, and described tapped hole and face of weld intersection are provided with protruding ring.
Described protruding ring height is greater than the height of three square cambered surface projections.
Described annulus edge is rounded feature.
Adopt design proposal of the present utility model, at the face of weld of T type nut, three square cambered surface projections and protruding ring are rationally set, when welding, T type welded nut is close to parts, only have the annular projection of T type welded nut to contact with parts with square cambered surface projection, after welding, just can guarantee quality and the intensity of welding.
The utlity model has that welding quality is good, the high advantage of weld strength.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is plan view of the present utility model.
Fig. 3 is side view of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1: the annulus 3 that the utility model comprises T-shaped nut body 4 and is connected as a single entity with T-shaped nut body 4, described T-shaped nut is round structure 2, is provided with radial screw bore 1 in the middle of round structure 2,
As shown in Figure 2: described T-shaped nut body 4 is provided with three square cambered surface projections 5 with parts face of weld 7, and described three square cambered surface projections 5 are arranged and are equilateral triangle shape, and described tapped hole 1 is provided with protruding ring 6 with face of weld 7 intersections.
As shown in 3 figure: as described in protruding ring 6 be highly greater than the height of three square cambered surface projections 5, described annulus 3 edges are rounded feature 8.
By three square cambered surface projections and protruding ring are rationally set at the face of weld of T type nut, when welding, T type welded nut is close to parts, only have the annular projection of T type welded nut to contact with parts with square cambered surface projection, after welding, just can guarantee quality and the intensity of welding.
Claims (1)
