Abstract
The utility model discloses a screw fastener, which comprises a bolt and a screw fastener cover. The screw fastener cover comprises a screw nut and a screw body, a threaded taper hole extending from the screw nut to the screw body is arranged in the middle of the screw fastener cover, the diameter of the threaded taper hole is reduced gradually, a through groove penetrating along the diameter direction and extending from the head of the screw body to the screw nut is at least arranged on the screw body, and the bolt can be screwed in the threaded taper hole to swell the diameter of the screw body. The screw fastener enables a connected member to be fixed on a connecting base through a screw fastener cover diameter swelling mode, and threads of the bolt do not bear gravity of the connected member and influence of other impact fore, thereby preventing the threads from being damaged. Therefore, the screw fastener can be reused after disassembly, thereby reducing maintenance cost and avoiding waste.
Description
Technical field
The utility model relates to a kind of mechanical fastener, particularly a kind of screw.
Background technique
In the existing technology, the engineering machinery interior trim generally adopts the disposable plastic screw to fix, and screw utilizes its worm tooth that interior trim is fixed on the basis, and worm tooth can receive interior trim gravity and other impulsive load influence for a long time, so worm tooth damages easily.When the maintenance interior trim, generally with after the plastic screw dismounting, the screw thread tooth just can be broken, can't reuse.Therefore adopt this screw can increase maintenance cost, and can cause waste of material.
Therefore need improve this screw of the prior art.
The model utility content
In view of this, the purpose of the utility model provides a kind of screw thread nail catcher, and it is reusable, with the user cost of reduction screw thread nail catcher, and avoids waste of material.
The utility model screw thread nail catcher; Comprise bolt and nail catcher cover; Said nail catcher cover comprises the head of a nail and nail body; Nail catcher cover middle part is provided with from the head of a nail extends and the diminishing threaded taper hole of diameter to the nail body, and nail is provided with the groove that runs through and extend to the head of a nail from nail body head along diametric(al) on one's body at least one, and bolt can screw in threaded taper hole and will follow closely the body diameter and swell.
Further, said bolt and nail catcher cover are made of plastics,
Further, said nail is provided with the orthogonal groove of twice on one's body.
The beneficial effect of the utility model: the utility model screw thread nail catcher; Be that mode through the nail catcher cover diameter that swells is fixed in connected piece and connects on the basis; The worm tooth of bolt no longer bears the gravity of connected piece and the influence of other impact force, thereby can avoid the damage of worm tooth, thus this drive screw to be buckled in the dismounting back also reusable; Can reduce maintenance cost, avoid waste.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is the overall structure sectional view of the utility model screw thread nail catcher;
Fig. 2 is the nail catcher cover sectional view of the utility model screw thread nail catcher;
Fig. 3 is the schematic perspective view of the utility model nail catcher cover.
Embodiment
Fig. 1 is the overall structure sectional view of the utility model screw thread nail catcher; Fig. 2 is the nail catcher cover sectional view of the utility model screw thread nail catcher; Fig. 3 is the schematic perspective view of the utility model nail catcher cover.
As shown in the figure; Present embodiment screw thread nail catcher; Comprise bolt 1 and nail catcher cover 2, said nail catcher cover 2 comprises head of a nail 2a and nail body 2b, and nail catcher cover middle part is provided with from head of a nail 2a extends and the diminishing threaded taper hole 2c of diameter to nail body 2b; At least be provided with the groove 2d that runs through and extend to the head of a nail from nail body head along diametric(al) for one on the nail body 2b, bolt 1 can screw in threaded taper hole 2c and will follow closely the body diameter and swell.
The utility model screw thread nail catcher; Mode through the nail catcher cover diameter that swells is fixed in connected piece on the connection basis; The worm tooth of bolt no longer bears the gravity of connected piece and the influence of other impact force, thereby can avoid the damage of worm tooth, thus this drive screw to be buckled in the dismounting back also reusable; Can reduce maintenance cost, avoid waste.
As the improvement to this embodiment, said bolt 1 is made of plastics low cost of manufacture with nail catcher cover 2.
As the improvement to this embodiment, said nail body 2b is provided with the orthogonal groove 2d of twice, and this structure nail body leading portion is divided into 4 parts by groove, and by bolt 1 extruding the time, the nail power of experiencing is even, easily by distending, and is difficult for cracking.Certainly in different embodiment, the quantity of groove can also be worth for other, and groove quantity is many more, and the nail body is easy in more distending, but the intensity of nail body is also low more.
Explanation is at last; Above embodiment is only unrestricted in order to the technological scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technological scheme of the utility model; And not breaking away from the aim and the scope of the utility model technological scheme, it all should be encompassed in the middle of the claim scope of the utility model.
