Abstract
The utility model provides a kind of rivet nut Stud connection device, and the rivet nut (4) including no internal screw thread and the stud (5) with annular knurl, one end of the rivet nut (4) of no internal screw thread is provided with flange；The internal diameter of the rivet nut (4) of no internal screw thread is smooth periphery；Stud (5) with annular knurl has front end and root, wherein is provided with screw thread on the stud of front end, is provided with annular knurl (6) on the stud of root；The internal diameter of the rivet nut (4) of no internal screw thread is less than the knurled outside diameter of the stud (5) with annular knurl；When the rivet nut (4) of no internal screw thread is in conjunction with the knurled outside diameter of the stud (5) with annular knurl, under axial pressure effect, interference fit is formed.The program changes the structure of rivet nut and stud and the principle of compression, greatly improves production efficiency, reduces cost.
Description
Technical field
The utility model relates to a kind of attachment device more particularly to a kind of rivet nut Stud connection devices.
Background technique
Staking refers to that in riveting process, riveting parts are plastically deformed under the action of external tensile force, the position of deformation
It sets usually at the position specially designed, clamps substrate by deformation position to realize reliable connection.Staking stud is one kind in work
The fastener used in industry, as shown in Figure 1, existing staking stud is composed of and existing rivet nut 2 and stud 1
Staking stud is first to be screwed into stud by rivet nut 2, is screwed to bottom always, as shown in Fig. 2, then using a kind of mold of complexity
Impression 3 is extruded in the root of nut, rivet nut 2 and stud 1 is then made to be fixed together, this mode die cost is very high,
Low efficiency causes the cost of part itself also very high, while the anti-torsion performance of part is also relatively low.
Utility model content
The purpose of this utility model is to provide
The technical solution of the utility model is there is provided a kind of rivet nut Stud connection device, the drawing including no internal screw thread
Riveting nut and stud with annular knurl, one end of the rivet nut of no internal screw thread is provided with flange；Rivet nut without internal screw thread
Internal diameter is smooth periphery；Stud with annular knurl has front end and root, wherein is provided on the stud of front end
Screw thread is provided with annular knurl on the stud of root；The internal diameter of the rivet nut of no internal screw thread is less than the rolling of the stud with annular knurl
Flower outer diameter；When the rivet nut of no internal screw thread is in conjunction with the knurled outside diameter of the stud with annular knurl, in the case where being acted on along axial pressure,
Form interference fit.
Further, the rivet nut outer diameter of no internal screw thread is provided with annular knurl close to the peripheral surface of flange portion.
The utility model has the beneficial effects that: the scheme of the utility model be made that on existing staking stud it is great
Improvement, the program by change rivet nut and stud combining form, change the structure and pressure of rivet nut and stud
Tight principle, greatly improves production efficiency, reduces cost.
Detailed description of the invention

Fig. 4 is the schematic diagram of the rivet nut described in utility model without internal screw thread and the stud secure bond with annular knurl；
Wherein: 1- stud, 2- rivet nut, 3- impression, rivet nut of the 4- without internal screw thread, stud of the 5- with annular knurl, 6-
Annular knurl.
Specific embodiment
The technical solution of the utility model is described in detail below with reference to attached drawing 3-4.
As shown in figure 3, this embodiment offers a kind of rivet nut Stud connection devices comprising the staking without internal screw thread
Nut 4 and stud 5 with annular knurl.Wherein, one end of the rivet nut 4 of no internal screw thread is provided with flange；Staking without internal screw thread
4 outer diameter of nut is provided with annular knurl close to the peripheral surface of flange portion.The internal diameter of the rivet nut 4 of no internal screw thread is smooth circle
Circumferential surface；
Stud 5 with annular knurl has front end and root, wherein it is provided with screw thread on the stud of front end, it is close
Annular knurl 6 is provided on the stud of root.
The internal diameter of the rivet nut 4 of no internal screw thread is less than the knurled outside diameter of the stud 5 with annular knurl.
When the rivet nut 4 of no internal screw thread is in conjunction with the knurled outside diameter of the stud 5 with annular knurl, acted on along axial pressure
Under, form interference fit.
The rivet nut Stud connection device of the embodiment is in use, be placed in band annular knurl for the rivet nut 4 of no internal screw thread
The top of stud 5, the device is compared with existing staking stud 1 in the prior art, since the rivet nut 4 of no internal screw thread can be square
Just pass through the stud 5 with annular knurl, when being provided with annular knurl 6 on its stud close to root, as shown in Figure 4: produced using press
The rivet nut 4 of no internal screw thread is pressed into the stud 5 with annular knurl by raw press pressure 7, and then entire technique just completes.
Although the principles of the present invention are described in detail in the preferred embodiment above in conjunction with the utility model,
It should be appreciated by those skilled in the art that above-described embodiment is only the explanation to the exemplary implementation of the utility model, and
The non-restriction to the utility model scope.Details in embodiment does not constitute the limitation to the scope of the utility model, In
Without departing substantially from the utility model spirit and scope in the case where, any equivalent transformation based on technical solutions of the utility model, letter
Single replacement etc. is obvious to be changed, and is all fallen within scope of protection of the utility model.
