Abstract
The utility model discloses a screw, including nail body and nut, the nail distributes threadedly on one's body, the nut sets up in the one end of nail body, the fluting has been seted up with the other end that the nail body is connected to the nut, can dismantle on the nut is connected with the lid, set up the caulking groove with nut looks adaptation on the lid, be provided with the barb ring on the cell wall of caulking groove, the circular groove with barb ring matched with has been seted up on the nut. The utility model discloses can carry out effectual protection to the fluting on the nut.
Description
Technical field
The utility model relates to a kind of mechanical parts, and more particularly, it relates to a kind of screw.
Background technique
Screw uses in mechanical field in a large number as fastening piece, and its fixation is realized by the cooperation of screw and screw.
In the prior art, after screw makes nail body be screwed into screw by the interaction of the fluting on screw rod and nut, nut is in naked state usually, if things go on like this, fluting on nut will suffer the erosion of humidity in air or rainwater and damage, and fluting is once be damaged, nail will be caused to continue after one's death cannot be back-outed again, thus causes follow-up screw cannot change or make the machinery by screw is fixing to dismantle.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of screw that can carry out available protecting to the fluting on nut.
For achieving the above object, the utility model provides following technological scheme: a kind of screw, and comprise nail body and nut, described nail is distributed with screw thread with it, and described nut is arranged at one end of nail body; The other end that described nut is connected with nail body offers fluting; Described nut is removably connected with lid; Described lid offers the caulking groove suitable with nut; The cell wall of described caulking groove is provided with barb ring; Described nut offers the circular groove matched with barb ring.
By adopting technique scheme; in use; after nail body is screwed into screw; lid is fastened on nut; thus fluting is covered, and pass through the mutual snap-fit engagement of barb ring and circular groove, lid is effectively fixed; compare prior art, and the utility model effectively can be protected the fluting on nut.
The utility model is set to further: one end that described lid is connected with nut is provided with and suitable protruding block of slotting.
By adopting technique scheme, when lid is fastened on nut, protruding block is embedding with fluting phase interfix, to fill fluting, avoids the existence of fluting internal clearance and air, reduces the possibility of slotting and being corroded, can protect by cross-notching further.
The utility model is set to further: the end that described nut is connected with lid offers circular arc chamfering along on excircle direction.
By adopting technique scheme, on the one hand can so that lid be fastened on nut, can avoid on the other hand operator in use scratch by nut, can strengthen further practicability of the present utility model.
The utility model is set to further: described lid is extended with lifting ear along on excircle direction.
By adopting technique scheme, in the unloading process of lid, providing Point of Strength, make the dismounting of lid more convenient.
Accompanying drawing explanation
Fig. 1 is the structural blast figure of the utility model screw embodiment;
Fig. 2 is that the structure of the utility model screw embodiment analyses and observe explosive view.
Reference character: 1, follow closely body; 2, nut; 3, screw thread; 4, slot; 5, lid; 6, caulking groove; 7, barb ring; 8, circular groove; 9, protruding block; 10, circular arc chamfering; 11, lifting ear.
Embodiment
Referring to figs. 1 through Fig. 2, the utility model screw embodiment is described further.
As shown in Figure 1 to Figure 2, a kind of screw, comprises nail body 1 and nut 2, and nail body 1 is distributed with screw thread 3, and nut 2 is arranged at one end of nail body 1; The other end that nut 2 is connected with nail body 1 offers fluting 4; Nut 2 is removably connected with lid 5; Lid 5 offers the caulking groove 6 suitable with nut 2; The cell wall of caulking groove 6 is provided with barb ring 7; Nut 2 offers the circular groove 8 matched with barb ring 7.
By adopting technique scheme, in use, after nail body 1 is screwed into screw, lid 5 is fastened on nut 2, thus fluting 4 is covered, and by the mutual snap-fit engagement of barb ring 7 with circular groove 8, lid 5 is effectively fixed; One end that wherein lid 5 is connected with nut 2 is provided with and 4 suitable protruding blocks 9 of slotting, when lid 5 is fastened on nut 2, protruding block 9 is embedding with fluting 4 phase interfix, to fill fluting 4, avoid the existence of fluting 4 internal clearance and air, reduce the possibility that fluting 4 is corroded; Compare prior art, and the utility model effectively can be protected the fluting 4 on nut 2.
The end that wherein nut 2 is connected with lid 5 offers circular arc chamfering 10 along on excircle direction, on the one hand can so that lid 5 be fastened on nut 2, can avoid on the other hand operator in use scratch by nut 2, can strengthen further practicability of the present utility model.
In above-mentioned embodiment, lid 5 is extended with lifting ear 11 along on excircle direction, in the unloading process to lid 5, provides Point of Strength, make the dismounting of lid 5 more convenient.
Wherein lifting ear 11 and lid 5 are formed in one; Fluting 4 is preferably cross recess; Wherein lid 5 is preferably the flexible materials such as rubber, has certain elasticity, more can be convenient to the dismounting to lid 5.
The above makes preferred implementation of the present utility model, and under not departing from the prerequisite of the utility model principle for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection domain of the present utility model.
