The invention discloses an embedded flange welding nut, which comprises: nut, ring flange and threaded sleeve pipe, the top surface fixed connection of nut and ring flange, the bottom surface fixed connection of threaded sleeve pipe and ring flange, threaded sleeve pipe's diameter is less than the inscribed circle of nut, ring flange and threaded sleeve pipe's central line collineation, set up the internal thread hole that link up in the middle of nut, ring flange and the threaded sleeve pipe, a plurality of welding points of the bottom surface evenly distributed of ring flange. Through the mode, the invention can ensure the stable welding fixing moment, improve the total meshing length between the bolt and the nut, and further improve the reliability of connecting members made of different materials under the condition of not using a gasket.
Description
Technical Field
The invention relates to the field of connecting pieces, in particular to an embedded flange welding nut.
Background
The bolt and the nut are usually used in a matched manner, the bolt and the nut are used for connecting two or more structural parts, the materials of the structural parts connected are different, particularly, one side of the structural part is a relatively thin metal plate, one side of the structural part is made of relatively thick plastic or wood and other relatively soft materials, in time, the material properties are different, the vibration frequency is relatively large when the bolt is stressed, the internal thread cannot be made of the relatively soft material, the bolt is easy to generate torque when being stressed or vibrated under a long-term stress or vibration environment, or the bolt is loosened, a mounting gasket is mounted between the connecting surface and the bolt and the nut in a common solution mode for solving the problems, the moment of meshing is improved, but the problem of loosening is still easily caused after the contact point of the connecting surface is deformed and solidified along with long-term stress in long-term use.
Disclosure of Invention
The invention mainly solves the technical problem of providing a welding nut which can improve the reliability of connecting different material components by the nut.
In order to solve the technical problems, the invention adopts a technical scheme that: the utility model provides an embedded ring flange weld nut, embedded ring flange weld nut includes: nut, ring flange and threaded sleeve, the top surface fixed connection of nut and ring flange, the bottom surface fixed connection of threaded sleeve and ring flange, threaded sleeve's diameter is less than the inscribed circle of nut, ring flange and threaded sleeve's central line collineation, set up the internal thread hole that link up in the middle of nut, ring flange and the threaded sleeve, a plurality of welding points of the bottom surface evenly distributed of ring flange.
In a preferred embodiment of the present invention, the nut is a hexagonal nut, and a reinforcing rib is disposed at a central axis of each surface of the hexagonal nut to connect the flange and the hexagonal nut.
In a preferred embodiment of the invention, each face of the hexagonal nut corresponds to a weld.
In a preferred embodiment of the invention, the welds are all disposed directly beneath the ribs.
In a preferred embodiment of the invention, an installation clamping groove is arranged at one end of the hexagonal nut far away from the flange plate.
In a preferred embodiment of the invention, a reinforcing ring is arranged at the connecting position of the threaded sleeve and the flange plate, and the thickness of the reinforcing ring is not more than 0.5 mm.
The invention has the beneficial effects that: the threaded sleeve embedded into the connecting surface is arranged on the basis of a conventional welding flange nut, the engagement length between the nut and the bolt is increased under the condition of not changing a basic structure through the threaded sleeve, so that the integral friction force after screwing is obviously increased, the falling torque or loosening after long-term use can be effectively prevented under the condition of not installing the gasket, the nut can be further prevented from withdrawing wires and falling the torque after welding on the flange surface, and the reliability of connection constructed by different materials is enhanced.

Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the invention.
Referring to figures 1, 2 and 3,
the embodiment of the invention comprises the following steps: an embedded flange weld nut, comprising: nut 1, ring flange 2 and threaded sleeve 3, nut 1, ring flange 2 and threaded sleeve 3 are through the mode integrated into one piece of cold-heading, nut 1 is fixed at the top surface of ring flange 2, threaded sleeve 3 is fixed in the bottom surface of ring flange 2, threaded sleeve 3's diameter is less than nut 1's inscribed circle, nut 1, ring flange 2 and threaded sleeve 3's central line collineation, set up the internal thread hole 6 that link up in the middle of nut 1, ring flange 2 and threaded sleeve 3.
Embedded ring flange weld nut sets up six welding points 5 altogether, six welding points 5 evenly distributed are in on the bottom surface of ring flange 2, and welding point 5 positions are under strengthening rib 4, and high fever can reduce the influence to ring flange 2 during the welding, improves the stability of connecting.
The one end that ring flange 2 was kept away from to hexagon nut sets up the installation draw-in groove, and is convenient the operation of embedded ring flange welded nut when installing improves nut 1 installation effectiveness.
Threaded sleeve 3 sets up reinforcing ring 7 with flange plate 2 hookup location, reinforcing ring 7's thickness is 0.5mm, reinforcing ring 7 can improve the joint strength of flange plate 2 and 3 connecting portions of threaded sleeve, prevents the reverse of the 3 atress back axis of threaded sleeve.
The using method of the embodiment comprises the following steps:
when the embedded flange plate welding nut is used, the threaded sleeve 3 is firstly placed in a preset hole in a connecting surface on one side, the nut 1 is screwed through the clamping groove 8 clamped on the nut 1 by a tool, so that the threaded sleeve 3 enters the preset hole as much as possible, then a bolt extends into an internal thread hole 6 of the threaded sleeve from the preset hole in the connecting surface on the other side, and the flange plate welding nut is embedded by a welding machine after the bolt and the nut 1 are screwed down and is fixed on the connecting surface through the welding point 5. Through the connection mode, the engagement length of the bolt and the threads can be effectively improved while certain welding fixing torque is provided, the influence of different vibration frequencies on the connection condition after materials made of different materials are stressed is further reduced, and the connection reliability is improved.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
