Abstract
The present invention relates to a kind of more solder joint welded nuts, including nut body, round boss and solder joint, its technical characterstic to be：The round boss for positioning is integrally made at the top of the nut body vertically, the nut body and round boss center are provided with tapped through hole；Along the circumferential direction uniform interval is formed with least three solder joints on nut body upper surface outside round boss.The present invention by 3 solder joints in the prior art on Hex welding nut body by increasing to 6 solder joints, firm welding.
Description
Technical field
The invention belongs to technical field of fastening, particularly a kind of more solder joint welded nuts.
Background technology
At present, in fastener products, for nut because its manufacturing process is simple, species is various, is widely recognized and uses.Its
In, welded nut refers to that one kind also needs to be welded with installing plate after nut fastening, therefore welded nut is in plain nut
Bottom end face is provided with for welding dot bulge.
But there are the following problems in welding process for welded nut of the prior art：
(1) bottom end of common Hex welding nut is only formed with 3 solder joints, welded nut not prison welding, semi-finished product
Welded nut easily comes off part in transportation or in transport process.
(2) existing Hex welding nut solder joint thickness is generally 0.8mm, due to solder joint height in actual welding operation
Too high, causing solder joint to melt, speed is slow, and welding effect is undesirable.
Through retrieval, do not find and the same or analogous prior art of the present invention.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of reasonable in design, simple in construction and welding jail
Solid more solder joint welded nuts.
The present invention solves its technical problem and takes following technical scheme to realize：
A kind of more solder joint welded nuts, including nut body, round boss and solder joint, vertically one at the top of the nut body
System goes out the round boss having for positioning, and the nut body and round boss center are provided with tapped through hole；Outside round boss
Nut body upper surface on along the circumferential direction uniform interval be formed with least three solder joints.
Moreover, more solder joint nuts are Hex welding nut, the quantity of the solder joint is 6.
Moreover, the solder joint thickness is 0.4mm.
Moreover, the shape of each solder joint is in reverse taper, round boss is pointed to by nut outer rim.
The advantages and positive effects of the present invention are：
1st, the present invention is welded by the way that 3 solder joints in the prior art on Hex welding nut body are increased into 6 solder joints
Firmly.
2nd, the present invention makes solder joint thinning, accelerates speed and the solder joint thawing of solder joint thawing by the way that solder joint thickness is reduced
Evenly, make welded nut and welding parent between be bonded it is even closer, welding it is more firm, weld seam is more smooth, attractive in appearance.
3rd, each solder joint of the invention is in reverse taper, points to round boss by nut outer rim, solder joint was melted gradually
Cheng Zhongneng is more uniformly paved with whole solder side, not only increases welded nut and welds the solder side between parent, makes its tight
It is close to weld together；And weld seam can be made more smooth, attractive in appearance.
Brief description of the drawings
Fig. 1 is the overall structure front view of the present invention；
Fig. 2 is the sectional view of Fig. 1 upward view.
Embodiment
The embodiment of the present invention is described in further detail below in conjunction with accompanying drawing：
A kind of more solder joint welded nuts, as depicted in figs. 1 and 2, including nut body 1, round boss 2 and solder joint 3, the spiral shell
Female bodies top integrally makes the round boss for positioning vertically, and the nut body and round boss center are provided with screw thread
Through hole；Along the circumferential direction uniform interval is formed with least three solder joints on nut body upper surface outside round boss.In this reality
Apply in example, more solder joint nuts are Hex welding nut, and the quantity of the solder joint is 6.
In the present embodiment, solder joint thickness is reduced to 0.4mm, solder joint thickness by the 0.8mm of solder joint nut in the prior art
Reduce, make solder joint thinning, accelerate the speed that solder joint melts and solder joint melts evenly, make between welded nut and welding parent
What is be bonded is even closer.When through test of many times, to show solder joint thickness be 0.4mm, the welding between welded nut and welding parent is imitated
Fruit is optimal.Not only avoided while dry joint phenomenon is freeed but also improved speed of welding.
In the present embodiment, the shape of each solder joint is in reverse taper, and round boss is pointed to by nut outer rim.Closer to spiral shell
The local solder joint of female body top surface outer rim is thicker, and the local solder joint closer to round boss is thinner.Be advantageous to make solder joint gradual
Whole nut body can be more uniformly paved with melting process and welds the solder side between parent, makes welded nut female with welding
Body its closely weld together；And weld seam can be made more smooth, attractive in appearance.
It is emphasized that embodiment of the present invention is illustrative, rather than it is limited, therefore present invention bag
Include and be not limited to embodiment described in embodiment, it is every by those skilled in the art's technique according to the invention scheme
The other embodiment drawn, also belongs to the scope of protection of the invention.
