Abstract
The utility model relates to the hardware fitting field, in particular to a permanent type quick nut. The permanent type quick nut comprises a nut body, wherein the upper portion of the nut body is circular-truncated-cone-shaped, the lower portion of the nut body is cylindrical, and a circular-truncated-cone-shaped opening part at the upper portion of the nut body is a cylindrical notch. The permanent type quick nut further comprises an annular anti-off retaining ring which is matched with the notch, a plurality of tooth forms are arranged on the inner circular ring position of the anti-off retaining ring, and the sides of the nut apply circular arc transition. Two objects of the nut and the anti-off retaining ring are combined, and therefore the nut and the anti-off retaining ring can be directly riveted on the objects of planks and the like by a die, twisting is unnecessary, and meanwhile tooth-shaped anti-off retaining ring can enhance elasticity and is stable. The permanent type quick nut has the advantages of being small in size, light in appearance, simple in structure, convenient to use, and capable of saving materials and reducing cost.
Description
Technical field:
The utility model relates to the hardware fitting field, relates to the quick nut of a kind of eternal-fixing-type in particular.
Background technique:
Nut is as a kind of fastening piece, and the general and supporting use of bolt, double-screw bolt and machine screw is used for being fastenedly connected two parts, makes it into as a whole.Existing nut generally has interior threaded hole, shape generally is flat hexagonal cylindricality, also have and be flat square column type or oblate cylindricality, fitted bolt is realized fastening, if be subjected to the impact of external force for a long time, screw thread is loosening easily, nut will get loose in the course of time, for many large-scale precision components or basis, be easy to and will have an accident, cause personal safety and the property loss that can't remedy, and existing nut profile is bigger, difficulty is installed, and it is light and handy therefore to be necessary to design a kind of profile, the quick nut of eternal-fixing-type easy to use carries out pemanent type to heavy connection and fixes.
The model utility content:
The purpose of this utility model is at the deficiencies in the prior art part, provides a kind of eternal-fixing-type quick nut, its economical with materials, and cost is low; Easy to use, direct riveted carries out pemanent type and fixes on objects such as plank during use, has avoided the nut phenomenon that gets loose.
Technology solution of the present utility model is as follows:
The quick nut of eternal-fixing-type comprises nut body, and described nut body top is frustoconic shape, and the bottom is cylindrical, and nut body top frustoconic shape oral area is cylindrical recesses; Described nut also comprises an annulus anti-avulsion clasp that matches with described recess.
In the technique scheme, the interior annulus place of described anti-avulsion clasp has a plurality of profiles of tooth.
In the technique scheme, arc transition is adopted on each limit of described nut.
The beneficial effects of the utility model are:
The quick nut of eternal-fixing-type of the present utility model is made up of nut and anti-avulsion clasp, two articles altogether just directly riveted on objects such as plank, need not twist, it is very fast, easy to use, solid, firm to lock, the intensity height.The anti-avulsion clasp is provided with a plurality of dentations simultaneously, and elastic force is good like this, and is firm, fixing easily when screw is thrown into, never gets loose.The utility model profile is light and handy, economical with materials, and cost is low.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is erection drawing of the present utility model.
Embodiment:
The following stated is preferred embodiment of the present utility model only, is not that scope of the present utility model is limited.
Embodiment sees attached Fig. 1 and 2, and the quick nut of eternal-fixing-type comprises nut body 1, and described nut body top is frustoconic shape, and the bottom is cylindrical, and nut body top frustoconic shape oral area is cylindrical recesses 2; Described nut also comprises an annulus anti-avulsion clasp 3 that matches with described recess.Nut and anti-avulsion clasp combine by the direct riveted of mould on objects such as plank during use, and be very easy to use.
The interior annulus place of described anti-avulsion clasp has a plurality of profiles of tooth 4, and elastic force is good like this, and is solid, and is firm.
Arc transition is adopted on each limit of described nut, avoids scratching the user like this in installation and using process.
