Abstract

The invention discloses a kind of screw of attached packing ring, it is related to machinery manufacturing technology field；Including rivet nut, the rivet nut is the screwed multi-diameter shaft in two ends, and packing ring is set in the small end of the multi-diameter shaft of the rivet nut, and the screw thread of the head of a nail and the small end is fastened together with merging.The present invention can solve current packing ring the problem of loss is dropped after dismantling screw.

Description

The screw of attached packing ring
Technical field
The present invention relates to machinery manufacturing technology field, especially a kind of screw.
Background technology
One of most common fastener during screw is people's work and lived, because its is simple in construction, manufacturing cost is low, Very popular, in the position that need to much fasten, all preferred screw of people is used as fastener；General screw is by following closely There is screw thread in body and head of a nail composition, rivet nut, the head of a nail is regular hexagon body, is convenient for people to be tightened or unclamped with spanner or other instruments Screw；Important or vibrate frequently workplace, screw will be used cooperatively with packing ring, to prevent screw from making Loosened with after a period of time；Common packing ring is generally becket, is enclosed in the rivet nut of screw, but in actual use process In, packing ring easily drops in knockout screw from rivet nut, causes packing ring to lose, and increases job costs.
The content of the invention
It is an object of the invention to provide a kind of screw of attached packing ring, it can solve current packing ring after dismounting screw The problem of loss that drops.
In order to solve the above problems, the technical solution adopted by the present invention is：Including rivet nut, the rivet nut is that two ends are carried The multi-diameter shaft of screw thread, packing ring is set in the small end of the multi-diameter shaft of the rivet nut, and the head of a nail is matched somebody with somebody with the screw thread of the small end and merges fastening Integrally.
In above technical scheme, further scheme can be：The reach of the small end is more than the head of a nail Thickness.
Further：The screw thread of the head of a nail and the small end is welded after tightening.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, the head of a nail and rivet nut are provided separately by the present invention, then packing ring is placed between the head of a nail and rivet nut, packing ring is kept with rivet nut Together, the phenomenon that coping screw nail dismounting causes packing ring to lose has been prevented；
2nd, the present invention is simple in construction, easy to use.
Brief description of the drawings
Fig. 1 is the front view of the present invention.
Fig. 2 is the top view of the present invention.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples：The screw of attached packing ring as shown in Fig. 1 ~ Fig. 2 Nail, including rivet nut 3, rivet nut 3 are the screwed multi-diameter shaft in two ends, and the hole of packing ring 1 is more than multi-diameter shaft end diameter and is less than rank Terraced axle outside diameter, packing ring 1 is enclosed on the small end of the multi-diameter shaft of rivet nut 3, and the screw thread of the head of a nail 2 and small end is fastened together with merging； The reach of small end is more than the thickness of the head of a nail 2；After the head of a nail 2 is tightened, the small end top surface of rivet nut 3 is concordant with the upper surface of the head of a nail 2.

Claims (3)

1. a kind of screw of attached packing ring, including rivet nut, it is characterised in that：The rivet nut is the screwed ladder in two ends Axle, packing ring is set in the small end of the multi-diameter shaft of the rivet nut, and the screw thread of the head of a nail and the small end is fastened together with merging.
2. the screw of attached packing ring according to claim 1, it is characterised in that：The reach of the small end is more than described The thickness of the head of a nail.
3. the screw of attached packing ring according to claim 1 or 2, it is characterised in that：The spiral shell of the head of a nail and the small end Line is welded after tightening.
