Abstract
The utility model relates to a combination insert self-locking nut, which comprises a nut head. A nut post is arranged below the nut head; the middle of the nut post is provided with a blind threaded hole; the lateral surface of the nut head is provided with a first reticulated pattern; the joint of the nut head and the nut post is provided with a nut step; the lateral surface of the nut post is provided with a second circular groove; the surface of the second circular groove is provided with at least one groove; a groove bulge formed by processing the groove is arranged on the inner surface of the blind threaded hole; the outer surface of the nut post is provided with a nut sleeve; the nut sleeve covers on the groove; and the nut post and the nut sleeve are in interference fit. When the combination insert self-locking nut is used, a higher torque is needed, thus, a screwed-in part is firm, cannot fall and is shock-resistant; the nut post cannot deform because of extrusion by the nut sleeve and is better combined with a plastic plate, thus, the nut post is prevented from rotating; a self-locking effect is realized, a higher concentrated force can be borne and a better sealing effect is achieved by the groove bulge; and the first circular groove and the reticulated pattern can be used for effectively increasing anti-drawing stress, thrust resistance and torque resistance.
Description
Technical field
The utility model relates to a kind of nut structure, especially a kind of combination inserts self-locking nut.
Background technique
Existingly be installed in the embedded nut on the plastic board through injection molding way; Prevent the combining to reach of reticulate pattern flower through the nut head and plastic board the purpose of rotating; Frictional force between the common nuts and bolt realizes locking; But the reliability of this locking reduces in dynamic load, and the loosening phenomenon in threaded connection place can take place, and can not keep the safety in production; Because the Nut column side is thinner, when embedding, can produce stress and make its distortion, and then internal thread deforms, like this other part can not be installed, increase reject rate; Self-locking nut substantially can divide two kinds on the market, and a kind of is that nut inside has nylon ring to reach the self-locking effect, but nylon ring is under the high temperature of Shooting Technique, and nylon ring can damage, thereby loses auto-lock function; Also having a kind of is self-locking nut through mechanical mechanism, such as the hexagonal self-locking nut, through injection moulding; After the hexagonal self-locking nut is advanced plastic by hot melt, cooling forming, plastic plate forms effective thread; But this method; Can torque resistant, but be easy to be pushed out and pull out, use so be not suitable for injection moulding.
Summary of the invention
The utility model technical problem to be solved provides a kind of combination inserts self-locking nut of firm torque resistant, tension pull out force, anti-release power, high tenacity being installed and having auto-lock function that can not become flexible.
The technological scheme that its technical problem of the utility model solution is taked is: a kind of combination inserts self-locking nut; Comprise the nut head; Nut head below is provided with Nut column, and the centre of Nut column is provided with tapped blind hole, and the side surface of nut head is provided with first reticulate pattern flower; The joint of nut head and Nut column is provided with the nut step; It is characterized in that: the side surface of described Nut column is provided with second circular groove, and the surface of second circular groove is provided with at least one groove, and the groove that on the internal surface of tapped blind hole, has machined grooves to form is protruding.
Further, described groove is three.
For the intensity that makes Nut column is higher, further, described Nut column outer surface is provided with nut sleeve, and nut sleeve covers on the groove, Nut column and nut sleeve interference fit.
In order to prevent that nut sleeve from rotating and be connected more fasteningly with working of plastics, described nut sleeve comprises nut sleeve head and nut sleeve column, and the side surface of nut sleeve head is provided with second reticulate pattern flower.
For combination inserts self-locking nut can better be combined with plastic board, increase the tension pull out force and the anti-release power of product in addition, form one first circular groove between described nut head and the nut sleeve head.
Further, the joint of described nut sleeve head and nut sleeve column is provided with the nut sleeve step.
The effect of having a mind to of the utility model is: adopted after the said structure, needed bigger moment of torsion when in use, can guarantee that the part that screws in is more firm; Can not drop, anti-vibration adopts nut sleeve to guarantee that Nut column can not deform because of extruding; Can better combine, prevent its rotation, adopt the groove convexity can realize the self-locking effect with plastic board; Can bear bigger single force and reach good sealing effect, adopt first circular groove and reticulate pattern flower, can effectively increase tension pull out force, anti-release power and twisting resistance; Make product be difficult in plastic board, being drawn out or releasing, also be not easy the situation that rotates.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the composite structure schematic representation of the utility model;
Fig. 2 is the left TV structure schematic representation of Fig. 1;
Fig. 3 is the structural representation of the utility model nut;
Fig. 4 is the structural representation of the utility model nut sleeve.
Among the figure: 1, nut head; 2, Nut column; 3, nut sleeve head; 4, groove; 5, groove is protruding; 6, first reticulate pattern flower; 7, nut step; 8, first circular groove; 9, second reticulate pattern flower; 10, nut sleeve step; 11, nut sleeve column; 12, tapped blind hole; 13, second circular groove.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in detail:
A kind of combination inserts self-locking nut as depicted in figs. 1 and 2 comprises nut head 1, and nut head 1 below is provided with Nut column 2; The centre of Nut column 2 is provided with tapped blind hole 12; The side surface of nut head 1 is provided with first reticulate pattern and spends 6, and nut head 1 is provided with nut step 7 with the joint of Nut column 2, and the side surface of described Nut column 2 is provided with second circular groove 13; The surface of second circular groove 13 is provided with three grooves 4, the groove protruding 5 that on the internal surface of tapped blind hole 12, has machined grooves 4 to form; Described Nut column 2 outer surfaces are provided with nut sleeve, and nut sleeve covers on the groove 4, Nut column 2 and nut sleeve interference fit; Described nut sleeve comprises nut sleeve head 3 and nut sleeve column 11, and the side surface of nut sleeve head 3 is provided with second reticulate pattern and spends 9; Form one first circular groove 8 between described nut head 1 and the nut sleeve head 3; Described nut sleeve head 3 is provided with nut sleeve step 10 with the joint of nut sleeve column 11.
The assembly process of combination inserts self-locking nut is, processes nut and nut sleeve respectively, and nut as shown in Figure 3, Fig. 4 are nut sleeve.Because nut and nut sleeve are interference fit, nut sleeve is enclosed within on the nut through press; To make up the inserts self-locking nut through injection molding way then is embedded in the plastic board.Because nut head 1 is equipped with the reticulate pattern flower with nut sleeve head 3, the groove of reticulate pattern flower combines to make nut to increase torsion, anti-release power and tension pull out force with plastic board closely; Because in the mobile step and first circular groove that is embedded on the nut sleeve of plastics, it is more fastening to cause combination inserts self-locking nut to be connected with plastic plate, tension pull out force and anti-release power in injection moulding process; Because the groove convexity 5 that has machined grooves 4 to form on the tapped blind hole 12 in the Nut column 2 can play self-locking action.
It is emphasized that: above only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technological scheme any simple modification, equivalent variations and modification that above embodiment did.
