Description
Technical field
The present invention relates to electric welding machine technical field, more particularly to a kind of electric welding machine casing working of plastics connection nut structure.
Background technology
At present in electric welding machine particularly housing design and manufacture, in order that product is attractive in appearance, generally using metal plate and plastics
The frame mode that part is combined, the casing metal plate and working of plastics of electric welding machine are usually required with mode connects for screw.
At present, there are following two fixed forms.
The first, as shown in figure 3, sheet metal nut 99:With thicker sheet metal, screw thread is directly done on sheet metal；Dress
Timing is put it into working of plastics mounting hole.The advantages of which is easy design, processing, and shortcoming is due to sheet metal nut 99
Enough frictional force, part easily slide in mounting hole with installation hole wall apodia.When dismounting casing, machine is stirred or vibrated, all
Sheet metal nut 99 can be made to be slided in mounting hole, screw is not easy to be directed at screwed hole, and part metals piece nut 99 even can be from
Skidded off in mounting hole, fall into casing, influence operating efficiency.
Second, as shown in figure 4, using standard nut 98；During assembling, standard nut 98 is placed on working of plastics make it is recessed
In pit hole.The shortcomings which is to need to extract installation pit out on the upside of mould, and mould is complicated, cost is high；In dismounting casing
When, standard nut 98 also easily drops out from pit slotted eye；Above all the area of standard nut 98 is small, it is impossible to pacifies screw
Caused power is distributed to remaining position of working of plastics in its vicinity during dress, and stress concentration easily makes working of plastics that fracture, fragmentation etc. occur
Quality problems.
Thus, the present inventor relies on experience and the practice for being engaged in relevant industries for many years, proposes a kind of electric welding machine casing plastics
Part connection nut structure, the defects of to overcome prior art.
The content of the invention
It is an object of the invention to provide a kind of electric welding machine casing working of plastics connection nut structure, overcome in the prior art
Existing not easy to assemble, easy to fall off, casing working of plastics easy fracture, the problems such as die cost is high, uniform stressed is realized, reduce casing
The breakages such as working of plastics fracture, use reliability is improved, dismounting is convenient, reduces cost.
The object of the present invention is achieved like this, a kind of electric welding machine casing working of plastics connection nut structure；The electric welding
Machine casing working of plastics connection nut structure can be dismantled and can be arranged in electric welding machine casing mounting groove, the electric welding machine casing
Working of plastics connection nut structure includes mainboard, and ligulate spring leaf, the ligulate spring leaf are set on the one side of the mainboard
Tilting end can along the mainboard thickness direction swing；Set on the one side of the mainboard along the thickness direction of the mainboard
There is connection bump portion, the screwed hole of insertion, the connection bump portion and the ligulate spring leaf are set in the connection bump portion
Positioned at the same side of the mainboard and spaced setting.
In the better embodiment of the present invention, the tilting end of the ligulate spring leaf is pacified towards the electric welding machine casing
The opening of tankage is set, and forms barb-shaped structure.
In the better embodiment of the present invention, on the one side of the mainboard and positioned at the ligulate spring leaf
The first end for tilting extreme direction sets positioning cams.
In the better embodiment of the present invention, the positioning cams are located at the first of the one side of the mainboard
Hold and be integrally formed along the both ends on the width of the mainboard, the positioning cams with the mainboard.
In the better embodiment of the present invention, two on the width of the mainboard at the second end of the mainboard
End is provided with positioning step portion.
In the better embodiment of the present invention, the connection bump portion is the cup that composition is integrally stretched on the mainboard
Shape is raised, the raised interior setting screwed hole of the cup-shaped.
In the better embodiment of the present invention, the connection bump portion is the press fitting spiral shell being fixedly connected on the mainboard
Female or blind nut or welded nut.
In the better embodiment of the present invention, the mainboard is rectangle cold rolled metal harden structure.
In the better embodiment of the present invention, the electric welding machine casing working of plastics connection is integrated punching with nut structure
Press bending structure.
From the above mentioned, electric welding machine casing working of plastics connection provided by the invention is had the advantages that with nut structure：
(1) in electric welding machine casing working of plastics connection nut structure of the invention, ligulate spring leaf can be with electric welding machine casing
The inwall of mounting groove, which leans, produces pressure, electric welding machine casing working of plastics connection is stuck in nut structure at link position, protects
