Abstract
The utility model relates to a locking and sealing bolt which comprises a screw rod and a screw cap; wherein the screw thread area of the screw rod is provided with a concave ring along the circumference, the concave ring is embedded with a locking and sealing ring, and the external diameter of the locking and sealing ring is slightly less than that of the screw thread and its internal diameter is less than that of the screw thread; the bottom surface of the concave ring is provided with a pit distributed along the circumference, and the internal surface of the locking and sealing ring is provided with a bulge matched with the pit. The utility model is convenient to be used, directly rotates into a blind screw hole or a through screw hole without adding any tools and parts when used in order to make the locking and sealing ring forcedly extruded the screw thread by the screw hole and closely combined with the screw hole through the elastic force of the locking and sealing ring, and thereby reaches the loose-proof, waterproof and oil-proof purpose.
Description
Technical field
The utility model belongs to the standard fasteners technical field, and what relate to is a kind of locking sealing bolt.
Background technique
Bolt is a kind of fastening piece of extensive use, and in use, because vibration tends to cause it loosening, this loosening meeting brings many serious harm, can not waterproof between screw rod and the screw, grease proofing, corrosion protection.For fear of this loosening, people adopt many methods, but effect is all desirable not to the utmost, because of complex structure, make difficulty, cost is high, uses is inconvenient, it is not good to act on or has destroyed scarce limit such as fastening piece original structure, are restricted and promote.
Summary of the invention
The purpose of this utility model be exactly be to overcome deficiency of the prior art and a kind of anti-loosening property of proposing reliable, lasting, save cost, easy to use, simple in structure, the life-span is long, and the locking sealing bolt of thorough waterproof, grease proofing, corrosion protection.
The purpose of this utility model is achieved in that and comprises screw rod and nut in described screw flight zone one scrobicular ring along side face is arranged, and is embedded with locking seal ring at this scrobicular ring, and its external diameter is slightly smaller than the external diameter of screw thread, and its internal diameter is less than the screw thread path; In the bottom surface of described scrobicular ring circumferential pit is arranged, the projection that cooperates with above-mentioned pit is arranged at the inner face of described locking seal ring.
The projection of the pit of described scrobicular ring bottom surface and locking seal ring inboard all has four and uniform along side face.
Described locking seal ring is by good springiness, wear-resisting and plastic injection-moulded making that plasticity is good.
The utility model is easy to use, using need not increase any instrument and part, directly screws in the blind screwhole or the saturating screw of body, makes locking seal ring be squeezed out screw thread by force by screw, and be closely linked, thereby reach locking, waterproof, grease proofing purpose by its elastic force and screw.
Description of drawings
Fig. 1 is a surface structure schematic representation of the present utility model;
Fig. 2 is Fig. 1 screw axial partial sectional view.
Embodiment
Referring to Fig. 1 and Fig. 2, the utility model comprises screw rod 1 and nut 2, at the threaded portion of described screw rod 1 scrobicular ring 3 along side face is arranged, and is embedded with locking seal ring 4 at this scrobicular ring 3, and its external diameter is slightly smaller than the external diameter of screw thread, and its internal diameter is less than the screw thread path.
Have along equally distributed four pits 5 of circumference in the bottom surface of described scrobicular ring 3, the projection 6 that cooperates with above-mentioned pit is arranged at the inner face of described locking seal ring 4.
Described locking seal ring is by good springiness, wear-resisting and plastic injection-moulded making that plasticity is good.What this embodiment adopted is nylon 1010.
The real motor that can be used for railway locomotive of the utility model is fixed, gearbox is fixed, diesel engine, fuel tank, water tank etc. fixing, be used for the installation of machine Component such as mining machinery, textile machinery, vibratory equipment and complete machine, use on the relevant open-work of same especially water tank, fuel tank, not only play locking effect, prevent the seepage of various liquid simultaneously.
