SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a T type welded nut for car to the welded nut who proposes among the above-mentioned background art of solution often can take place to warp and the displacement at welding process, places the easy deposition of in-process screw thread moreover for a long time and even oxidation problem.

In order to achieve the above object, the utility model provides a following technical scheme: a T-shaped welding nut for an automobile comprises a welding block and a nut; the welding block is arranged on the peripheral side face of the nut, the welding block is fixedly connected with the nut, a half thread is arranged on the inner surface of the nut, matching grooves are further formed in the surfaces of the two sides of the welding block, welding sheets are arranged in the matching grooves, a heat insulation ring is further arranged in the welding block, and the heat insulation ring is located on the outer side of the nut.

Preferably: a countersunk groove is formed in the surface of the welding block, and a protective plug is arranged in the countersunk groove.

Preferably: the bottom end of the nut is matched with a protective sleeve, and the protective sleeve is made of rubber.

Preferably: the welding block is made of carbon steel, and the nut is made of stainless steel.

Preferably: the thickness of the heat insulation ring is less than 2 mm.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model adopts carbon steel as the welding block, stainless steel as the nut, thereby saving materials and reducing cost, and the welding sheets are arranged on the peripheral side of the welding block, so that the welding block can be easily melted, the welding block and the automobile parts can be rapidly fused, and the deformation and displacement of the welding block caused by overlong welding time can be prevented; meanwhile, the heat insulation ring is arranged in the welding block, so that the time of transferring heat to the thread is delayed, and the thread deformation can be effectively prevented; in addition, the utility model discloses an use lag and protection stopper, avoid the nut to place the in-process internal thread deposition for a long time, oxidation.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a T-shaped welding nut for an automobile comprises a welding block 1 and a nut 5; the welding block 1 is arranged on the side surface of the periphery of the nut 5, the welding block 1 is fixedly connected with the nut 5, the inner surface of the nut 5 is provided with a half thread 501, the surfaces of two sides of the welding block 1 are also provided with matching grooves 6, welding sheets 4 are arranged in the matching grooves 6, a heat insulation ring 7 is also arranged in the welding block 1, and the heat insulation ring 7 is positioned on the outer side of the nut 5; in the structure, the soldering lug 4 can be melted by high temperature very fast when welding, thereby the position of the fixed welding block 1 prevents the displacement of the welding block 1 from influencing the welding quality, and partial heat can be blocked by the heat insulation ring 7 when the heat passes through the welding block 1, so that the heat transfer time is effectively delayed, and the deformation of the welding block 1 and the nut 5 in the welding process is avoided.

A countersunk groove 8 is formed in the surface of the welding block 1, a protective plug 2 is arranged in the countersunk groove 8, and the protective plug can protect the half thread 501 and prevent dust deposition and oxidation.

The bottom end of the nut 5 is matched with a protective sleeve 3, the protective sleeve 3 is made of rubber, and the rubber has certain elasticity and is convenient to use.

The welding block 1 is made of carbon steel, the nut 5 is made of stainless steel, and the stainless steel has small deformation at high temperature, small thermal expansion coefficient and excellent material characteristics.

The thickness of the heat insulation ring 7 is less than 2mm, and if the heat insulation ring 7 is too thick, the structural strength of the welding block 1 is affected, and the thickness is generally 1-2 mm.

The working principle is as follows: for the T-shaped welded nut, before use, the protective sleeve 3 and the protective plug 2 can be taken down, and then the welding sheets 4 on the two sides of the welding block 1 are melted by a welding gun, so that the welding block 1 is fixedly connected with the automobile parts, and the welding block 1 is prevented from deforming and displacing in the next step; in addition, in the welding process, partial heat can be delayed by the heat insulation ring 7, so that the deformation of the half thread 501 caused by overhigh temperature is effectively avoided, and the nut 5 is made of stainless steel and has the characteristic of high temperature resistance, so that the deformation of the nut 5 is further prevented.

It should be noted that the nut 5 of the present invention employs the half thread 501, and because the half thread 501 is inside the heat insulation ring 7, the heat transfer is slow, the temperature of the half thread 501 is low, and if the full thread mode is employed, the temperature of the upper end of the thread will be too high, and there is a risk of deformation.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
