Description
Technical Field
The utility model relates to a fastener technical field, more specifically say, it relates to a weld firm welded nut fastener.
Background
The welding nut is suitable for being welded outside the nut, is a fastener which is provided with internal threads and is matched with a screw rod for use, and has the advantages of wide application range, high strength, high temperature resistance and difficult deformation.
However, when the conventional welding nut is welded, the welding port between the fastener and the welding nut is easily cracked due to poor welding quality, low welding strength and loose fixation of the fastener, and the nut for connecting the fastener is slowly corroded to be loosened.
Therefore, a new technical solution is needed to solve the above problems.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a weld firm welded nut fastener.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a welded nut fastener that welds firmly, is including seting up female screw thread cylinder, the bottom lateral wall of screw thread cylinder is provided with the weld part, screw thread cylinder cover is equipped with the strengthening ring, the external diameter of strengthening ring is less than the external diameter of weld part, the strengthening ring evenly is provided with the connecting rod that a plurality of levels set up along its outside wall, the tip of connecting rod stretches out the lateral wall and the vertical decurrent gag lever post of fixedly connected with of weld part, the bottom fixed connection of gag lever post has the welding plate that the level set up, the surface of screw thread cylinder is provided with external screw thread and threaded connection has the nut.
Through adopting above-mentioned technical scheme, when using this fastener to connect, carry out threaded connection with the screw thread cylinder and threaded rod, screw up the back to the screw thread cylinder and locate the screw thread cylinder with the reinforcement ring cover, make its lower surface arrange the upper surface of weld part in, weld the weld part again, weld plate and work piece surface and weld, after the welding is accomplished, at the external screw thread with nut threaded connection in the surface of screw thread cylinder for the lower surface of nut supports tightly in the upper surface of reinforcement ring, thereby has promoted the joint strength to the work piece greatly.
The utility model discloses further set up to: the upper surface of the welding part is provided with a plurality of positioning holes, and the lower surface of the reinforcing ring is provided with positioning rods inserted into the positioning holes.
Through adopting above-mentioned technical scheme, when locating the reinforcing ring cover on the screw thread cylinder, aim at the locating hole with the locating lever for the locating lever is inserted and is located in the locating hole, when being convenient for install the location to the reinforcing ring, further promotes the joint strength between screw thread cylinder and the reinforcing ring, thereby promotes the bulk connection intensity of this connecting piece.
The utility model discloses further set up to: and the surface of the welding plate is provided with a welding hole.
Through adopting above-mentioned technical scheme, further promote the welding quality to the welding plate through the welding hole to promote its joint strength, thereby strengthen the joint strength of this fastener.

Detailed Description
Embodiments of the present invention are further described with reference to fig. 1 to 4.
The utility model provides a welded nut fastener that welds firmly, is including seting up threaded cylinder 1 that has internal thread 2, and the bottom lateral wall of threaded cylinder is provided with weld part 3, and 1 cover of threaded cylinder is equipped with reinforcing ring 4, and reinforcing ring 4's external diameter is less than weld part 3's external diameter, and reinforcing ring 4 evenly is provided with the connecting rod 5 that a plurality of levels set up along its outside wall, and the tip of connecting rod 5 stretches out weld part 3's lateral wall and the vertical decurrent gag lever post 6 of fixedly connected with, and the bottom fixed connection of gag lever post 6 has the welding plate 7 that the level set up, the bottom and the welding plate 7 of threaded cylinder all are regular hexagon, and threaded cylinder 1's upper portion is the cylinder and its surface is provided with external screw thread 8, and.
When using this fastener to connect, carry out threaded connection with threaded cylinder 1 and threaded rod, screw cylinder 1 is located reinforcing ring 4 cover after screwing up threaded cylinder 1, make its lower surface arrange the upper surface of weld part 3 in, again to weld part 3, weld plate 7 and workpiece surface weld, after the welding is accomplished, at the external screw thread 8 with the surface of nut 9 threaded connection in threaded cylinder 1, make the lower surface of nut 9 support tightly in the upper surface of reinforcing ring 4, thereby the joint strength to the work piece has been promoted greatly.
A plurality of locating holes 10 have been seted up to the upper surface of weld part 3, the lower surface of reinforcing ring 4 is provided with inserts the locating lever 11 of locating in locating hole 10, when locating reinforcing ring 4 cover on threaded cylinder 1, aligns locating lever 11 with locating hole 10 for the locating lever is inserted and is located in locating hole 10, when being convenient for install the location to reinforcing ring 4, further promotes the joint strength between threaded cylinder 1 and the reinforcing ring 4, thereby promotes the bulk joint strength of this connecting piece.
The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the ordinary changes and replacements performed by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
