Abstract
The utility model relates to a combined self-locking nut which comprises a nut head and two washers, wherein one end of the nut head stretches out of the nut neck, and an outward turned riveting edge is arranged at the top end of the nut neck; the washers are installed on the nut neck, and the outer diameter formed by the turned riveting edge is greater than the inner diameter of the washers; at least three radially and evenly distributed strip-shaped bulges are arranged on one side of each washer, and at least three radially and evenly distributed slope-shaped bulges are arranged on the other side of the washer; annular accommodating parts for accommodating the turned riveting edge are arranged on the washers, and the total height of the nut neck and the turned riveting edge is smaller than the total height of the two washers. After the structure is adopted, the nut and the washers can be combined together with the turned riveting edge, so that the combined nut is convenient to install and use; and the radial strip-shaped bulges arranged on the washers can play the non-slip effect, and the arranged slope-shaped bulges can be mutually engaged to play the locking effect.
Description
Technical field
The utility model relates to a kind of nut structure that fixation workpiece is used that connects, and especially relates to a kind of combination self-locking nut.
Background technique
At present; Existing lock washer is provided with the effect that dentation reaches anti-skidding locking through the top and bottom of lock washer, and this packing ring has increased anti-skidding effect, still DeGrain aspect locking; The environment relatively more severe in vibration can drop easily, such as being installed on the track for a train; A kind of gasket construction is arranged, adopt the lock washer of two band helical teeth, screw adopts this packing ring to be used; Interlock through helical teeth reaches locking effect; Locking effect is obvious, but it is complicated to adopt two packing rings to install when in use usually, the less local bad installation in the space; Increased the man-hour of workman's work, the manufacturing efficiency in the unit time reduces.
Summary of the invention
The utility model technical problem to be solved provides a kind of convenient combination self-locking nut of installing and can enhancing productivity.
The technological scheme that its technical problem of the utility model solution is taked is: a kind of combination self-locking nut; Comprise nut head and two packing rings; The first end of described nut is extended with nut neck; The top of nut neck is provided with the outside riveting limit of turning over, and packing ring is installed on the nut neck, turns over external diameter that the riveting limit the forms internal diameter greater than packing ring.
For the self-locking and the skidproof effect that can increase packing ring, described packing ring one side is provided with at least three strip projected parts and is radial even distribution; The opposite side of packing ring is provided with at least three sloping shape convexities and is radial even distribution.
For when installing, turn over the riveting limit with the workpiece contact that is connected, described packing ring is provided with and holds the ring-type of turning over the riveting limit and hold the place, further, described nut neck and the height that turns over the riveting limit and less than the height of two packing rings with.
The beneficial effect of the utility model is: adopted after the said structure, turning over the riveting limit can be with nut and washer combinations together, the convenient installation, the convenient use; Have radial strip bulge can play skidproof effect on the packing ring, it is protruding also to be provided with sloping shape, the protruding engaged effect that can play locking of sloping shape.
Description of drawings
Fig. 1 is the fractionation structural representation of the utility model;
Fig. 2 is the package assembly schematic representation of the utility model.
Among the figure: 1, nut neck; 2, turn over the riveting limit; 3, annular is held the place; 4, nut head; 5, packing ring; 6, strip projected parts; 7, sloping shape is protruding.
Embodiment
A kind of combination self-locking nut as depicted in figs. 1 and 2; Comprise nut head 4 and two packing rings 5, described nut head 4 one ends are extended with nut neck 1, and the top of nut neck 1 is provided with the outside riveting limit 2 of turning over; Packing ring 5 is installed on the nut neck 1, turns over the internal diameter of the external diameter of riveting limit 2 formation greater than packing ring 5; Described packing ring 5 one sides are provided with at least three strip projected parts 6 and are radial even distribution; The opposite side of packing ring 5 is provided with at least three sloping shapes protruding 7 and is radial even distribution; Described packing ring 5 be provided with hold the ring-type of turning over riveting limit 2 hold the place 3; Described nut neck 1 and the height that turns over riveting limit 2 and less than the height of two packing rings 5 with.
When using; Bolt passes through through hole; To rivet good combination self-locking nut afterwards twists and is connected on the bolt; The hardness of the hardness ratio workpiece of packing ring 5 is high, and the strip projected parts 6 on the packing ring 5 and nut head 4 contacts interlock and play anti-skidding and the effect of locking with workpiece surface, and the use of working in coordination of the sloping shape convexity 7 on two packing rings 5 can make locking effect more obvious; When tightening, the workpiece surface interlock that the strip projected parts 6 on packing ring 5 surfaces is contacted with it; The friction factor at protruding 7 places of sloping shape of two packing rings 5 is lower than the friction factor of strip projected parts 6 and workpiece contacting point, and displacement only can occur between the sloping shape protruding 7 of packing ring 5, until reaching the minimum pretightening force of error; The protruding 7 screw thread gradients greater than bolt of sloping shape between the packing ring 5, therefore, packing ring 5 prolongs the distensible distance of thickness direction and prolongs the producible length travel of hand of spiral greater than bolt.Loosening cause packing ring 5, and then cause clamping force and increase, make the adjustment that resets automatically of locking system in thickness direction generation expansion 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.
