Abstract

The utility model provides a locknut, which is provided with a screw nut which is provided with internal threads and can be screwed with a screw. The utility model is characterized in that the upper part of the screw nut is provided with a hollow jogged seat which upwards protrudes and extends. A hollow nylon ring sleeve is fixed in the hollow jogged seat. The hollow nylon ring sleeve is clamped, pressed and fixed by an inversion hooking part on the tail end of the hollow jogged seat to form a plasticity tightening part after a screw is screwed in. A bag cap which can cover an outer extension end after the screw is screwed in can be welded on the jogged seat. After the screw and the screw are screwed, the utility model has the functions of tightening and anti-loosing once because the hole diameter of the nylon ring sleeve is a little smaller than the diameter of the screw hole of the screw nut, and the nylon ring sleeve is plastic material which can be embedded through deformation. The bag cap can play the role of preventing scrape and laceration.

Description

A kind of anti-loosing type CAP NUTS nut

The utility model relates to a kind of fastenings, particularly a kind of anti-loosing type CAP NUTS nut.

Bolt is the most normal a kind of use and the fastening piece that loses nowhere, it is made up of the screw and nut that has the phase rotary screwing thread, though it is a kind of convenient and practical fastening piece, but also there are following problems and shortcoming, first: be connected because nut and screw are the rigidity contact, vibrate and external force is done the time spent meeting, more loosening, this becoming flexible not only makes between object and can not combine closely, and, easily become flexible and initiation mechanical failure and accident.In addition, for comparatively reliable firm needs on connecting, behind general nut and the screw-driving, screw all has a bit of not end that exposes, and this is not held and not only easily draws the hook personage, sometimes, also can scratch human body, is not fool proof.

The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of prior art, and a kind of bolt looseness that both can prevent is provided, and has anti-hook to draw the safe and practical anti-loosing type CAP NUTS nut of CAP NUTS.

The purpose of this utility model is to realize by following technological scheme:

The utility model has a nut that has internal thread of screwing mutually with screw, it is characterized in that: a convex hollow embedding seat that prolongs is arranged at the top of nut, at hollow embedding seat internal fixation one hollow nylon ring set is arranged, the hollow nylon ring set by the hollow embedding seat do not hold in turn over the hooked part card and press with fixed and constitute plasticity clamping part after a screw screws in, the CAP NUTS that outer stretched end buckle after welding one can be screwed into screw on the embedding seat covers, after screw and nut screw, because nylon ring cover aperture is slightly less than the plastic material that the screwhole diameter of nut also embeds for deformable, so have a locking effect of packing, CAP NUTS then can play the anti-effect that scratches.

Therefore remarkable result of the present utility model is as follows:

The 1st: because nylon ring cover aperture is slightly less than the plastic material that the screwhole diameter of nut also embeds for deformable, so have a locking effect of packing, CAP NUTS then can play the anti-effect that scratches.

The the 2nd: simple in structure, enforcement convenience.

Concrete structure of the present utility model is realized by the following examples and accompanying drawing:

Fig. 1 is STRUCTURE DECOMPOSITION figure of the present utility model;

Fig. 2 is the section of structure after Fig. 1 makes up;

Fig. 3 is using effect figure of the present utility model;

Below in conjunction with accompanying drawing 1-3 concrete structure of the present utility model is advanced detailed explanation:

The utility model has a nut that has internal thread 33 31 of screwing mutually with screw, it is characterized in that: the upper end at nut 31 upwards protrudes out the hollow embedding seat 32 that nylon ring set 34 is housed in again, have one inwardly to turn over and nylon ring set 34 is turned over hooked part 35 in fixing in the upper end of hollow embedding seat 32, be fixed with the CAP NUTS 36 that a outer stretched end buckle after screw is screwed into covers in hollow embedding seat 32 peripheries.Referring to Fig. 1 to Fig. 3

The diameter of bore of nylon ring set 34 is less than the diameter of the interior threaded hole 33 of nut 31, and nylon ring set 34 is fixed on the third ring platform place that hollow embedding seat 32 and the inner bolt hole 33 of nut form and constitutes and the outside thread of the screw plasticity clamping part of packing mutually.Referring to Fig. 2 and Fig. 3

The CAP NUTS 36 of bowl-shape is the outer shroud platform place 37 that is constituted that is weldingly fixed on nut 31 and the convex hollow embedding seat 32 that prolongs.Referring to Fig. 2 and Fig. 3

The CAP NUTS 36 of bowl-shape is to twist by screw thread to be fixed on outer shroud platform place 37 that nut 31 and the convex hollow embedding seat 32 that prolongs constituted.Referring to Fig. 3

Claims
