Description
Technical field
The utility model relates to machanical fastener field, is specifically related to a kind of self-clinching nut.
Background technique
Self-clinching nut is a kind of nut be applied on thin plate or panel beating, and profile is rounded, and one end is with emboss knobs and guiding groove.The function of rivet and nut rolls into one by self-clinching nut, does not want tapping thread during assembling, not welded nut, and rivet firm, convenient, fast, self-clinching nut is just used widely as a kind of novel fastener in the assembling of various product.Because matching board to be installed itself is thinner, can not tapping thread thereon, and require that the bottom surface of mating face is complete embedding flat, and after adopting existing common self-clinching nut to rivet it, there will be the situation of bar portion projection, thus reduce the fastening effect to buck plate.
For the problems referred to above, a kind of novel self-clinching nut is proposed in prior art, as shown in Figure 1, this technology is processed with a round ring boss 1 ' at the top of nut main body, and add emboss knobs 11 ' in the outside diameter hoop face of round ring boss 1 ', on round ring boss 1 ', be processed with an axial cross section is the annular boss 2 ' of inverted trapezoidal simultaneously, forms a wedge-shaped annular guiding groove 21 ', to realize without highlight bar portion and to rivet firmly effect between itself and the end face of round ring boss 1 '.But this self-clinching nut is usually for same kind, and the close accessory to be installed of deformability and preset aperture, and greatly reducing for the fixed effect of the different product in type, deformability and preset aperture, cannot meet the actual demand of people.
Model utility content
The utility model, in order to overcome above deficiency, provides the self-clinching nut of the fixed effect of the different product in a kind of effective raising type, deformability and preset aperture.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of self-clinching nut, comprises nut, is provided with a circle annular boss above described nut, be provided with turnup structure above described annular boss, between described turnup structure and annular boss, be provided with annular groove.
Further, described annular boss periphery is provided with a circle saw tooth structure.
Further, described saw tooth structure is formed by equally distributed pointed tooth.
Further, the external diameter of described annular boss is less than the external diameter of described nut.
Further, the longitudinal section of described annular groove is symmetrical arc.
Further, the center of described nut, annular boss, annular groove and turnup structure is provided with penetrating circular hole, is provided with internal thread in described circular hole.
Further, trapezoidal circular step is provided with between described annular boss and described annular groove.
Further, the height of described annular boss is 2.0-3.5mm, and the height of described annular groove is 4.0-5.5mm.
The utility model provides a kind of self-clinching nut, comprises nut, is provided with a circle annular boss, is provided with turnup structure above described annular boss, be provided with annular groove between described turnup structure and annular boss above described nut.By arranging annular boss, above annular boss, turnup structure is set, and annular groove is set between turnup structure and annular boss, type difference, deformability can be made different, and effectively fixing between the different product in preset aperture, reach and fit completely, without highlight bar portion and rivet firmly effect.The utility model simple and ingenious structure, effect stability is reliable, and the low input of cost is little, convenient to use, conscientiously meets the actual demand of people.
Accompanying drawing explanation
Fig. 1 is the structural representation of self-clinching nut in prior art;
Fig. 2 is the structural representation of the utility model self-clinching nut.
Shown in Fig. 1: 1 ', round ring boss; 11 ', emboss knobs; 2 ', the annular boss of inverted trapezoidal; 21 ', wedge-shaped annular guiding groove;
Shown in figure: 1, nut; 11, circular hole; 12, internal thread; 2, annular boss; 21, pointed tooth; 3, turnup structure; 4, annular groove; 5, trapezoidal circular step.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
As shown in Figure 2, the utility model provides a kind of self-clinching nut, comprises nut 1, is provided with a circle annular boss 2, is provided with turnup structure 3 above annular boss 2, be provided with annular groove 4 between turnup structure 3 and annular boss 2 above nut 1.By arranging annular boss 2, turnup structure 3 is set above annular boss 2, and annular groove 4 is set between turnup structure 3 and annular boss 2, type difference, deformability can be made different, and effectively fixing between the different product in preset aperture, reach and fit completely, without highlight bar portion and rivet firmly effect.
Preferably, the periphery of annular boss 2 is provided with a circle saw tooth structure, the comparatively large or product that deformability is stronger for fixed preset aperture, when fixing, first by pressure that the product that press machine is large by aperture preset in product to be fixed or deformability is stronger applies vertically downward, be pressed into annular boss 2, by product generation deformation and saw tooth structure close contact.
Preferably, saw tooth structure is formed by equally distributed pointed tooth 21, produces uniform frictional force between equally distributed pointed tooth 21 and product to be fixed, improves installation efficiency and fixed effect.
Preferably, the external diameter of annular boss 2 is less than the external diameter of nut 1, preset aperture is large or deformability is stronger product press-in annular boss 2, after fitting tightly with saw tooth structure, its lower surface and nut 1 also fit tightly simultaneously, now the external diameter of nut 1 is greater than the external diameter of annular boss 2, to realize effectively fixing this product, avoids product to run out of from this side.
Preferably, the longitudinal section of annular groove 4 is symmetrical arc, concrete, after preset aperture is large or that deformability is stronger product fixes, then be pressed in annular groove 4 by press machine from top to bottom by another product less for preset aperture or that deformability is less, the longitudinal section due to annular groove 4 is symmetrical arc, and top is turnup structure 3, this product can be fixed in annular groove 4 effectively, and can not run out of from turnup structure 3 side.
Preferably, the center of nut 1, annular boss 2, annular groove 4 and turnup structure 3 is provided with penetrating circular hole 11, is provided with internal thread 12 in circular hole 11, to realize being connected with the effective of other component.
Preferably, be provided with trapezoidal circular step 5 between annular boss 2 and annular groove 4, the outer peripheral surface of trapezoidal circular step 5 forms a wedge-shaped annular guiding groove, is convenient to realize fitting tightly of two products, and highlight bar portion can not be formed, further increase the effect that is locked.
Preferably, the height of annular boss 2 is 2.0-3.5mm, and the height of annular groove 4 is 4.0-5.5mm, usually carries out selection setting according to product to be fixed.
In sum, the self-clinching nut that the utility model provides, comprises nut 1, is provided with a circle annular boss 2, is provided with turnup structure 3 above annular boss 2, be provided with annular groove 4 between turnup structure 3 and annular boss 2 above nut 1.By arranging annular boss 2, turnup structure 3 is set above annular boss 2, and annular groove 4 is set between turnup structure 3 and annular boss 2, type difference, deformability can be made different, and effectively fixing between the different product in preset aperture, reach and fit completely, without highlight bar portion and rivet firmly effect.The utility model simple and ingenious structure, effect stability is reliable, and the low input of cost is little, convenient to use, conscientiously meets the actual demand of people.
Although be illustrated mode of execution of the present utility model in specification, these mode of executions just as prompting, should not limit protection domain of the present utility model.In the scope not departing from the utility model aim, carry out various omission, displacement and change all should be included in protection domain of the present utility model.
