Abstract
The utility model discloses a bolt of sealed function in area, move head, driving screw, connecting screw rod, auxiliary screw, elasticity sealing washer including twisting, driving screw one end is fixed with to twist moves the head, and the driving screw other end is fixed with connecting screw rod, the threaded hole in auxiliary screw middle part, connecting screw rod twists on the screw hole, all be equipped with the external screw thread on driving screw and the auxiliary screw, the elasticity sealing washer is arranged in the clearance between driving screw and the auxiliary screw. The utility model discloses a set up the elasticity sealing washer between driving screw and auxiliary screw for can obtain effectual sealedly with bolt complex screw is inside yet, prevent that liquid etc. From flowing out from the screw, have fine leakproofness yet when having guaranteed firm in connection, and the elasticity sealing washer does not expose externally, protected the elasticity sealing washer to a certain extent.
Description
【Technical field】
The utility model is related to the technical field of the technical field of securing member, particularly bolt.
【Background technology】
Bolt is a kind of conventional securing member, and it widely applies to the fields such as machinery, carpenter.It is higher in some needs
The occasion of sealing needs to use cooperatively sealing ring with bolt.Such using method often can only ensure between contact surface end face
Sealing, but for the raising of the sealing property of the screwed hole of installation bolt is not helped.
【Utility model content】
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of bolt with sealing function, energy
Enough make bolt that there is good sealing after installing.
For achieving the above object, the utility model proposes a kind of bolt with sealing function, including turning head, main spiral shell
Bar, connecting screw rod, auxiliary threaded rod, elastic seal ring, described driving screw one end is fixed with and turns head, and the driving screw other end is fixed with
There is screwed hole at connecting screw rod, the auxiliary threaded rod middle part, and connecting screw rod is screwed on screwed hole, on the driving screw and auxiliary threaded rod
External screw thread is equipped with, the elastic seal ring is located in the gap between driving screw and auxiliary threaded rod.
Preferably, described turn the rotation that head, driving screw and connecting screw rod are integral type structure, driving screw and connecting screw rod
Turn direction identical.
Preferably, external diameter of the elastic seal ring external diameter in an initial condition less than driving screw, driving screw external diameter
It is identical with auxiliary threaded rod external diameter.
Preferably, length of the length of the connecting screw rod less than screwed hole.
The beneficial effects of the utility model：The utility model by elastic seal ring by being arranged on driving screw and auxiliary threaded rod
Between so that effectively sealing is also obtained inside the screw coordinated with bolt, prevents liquid etc. from flowing out from screw, ensure that
Also there is good sealing while being connected firmly, and elastic seal ring is not exposed to outside, and bullet is protected to a certain extent
Property sealing ring.
Feature of the present utility model and advantage will combine accompanying drawing and be described in detail by embodiment.
【Description of the drawings】
Fig. 1 is a kind of front view of the bolt with sealing function of the utility model.
In figure：1- driving screws, 2- turn head, 3- connecting screw rods, 4- auxiliary threaded rods, 5- elastic seal rings, 10- external screw threads,
40- screwed holes.
【Specific embodiment】
Refering to Fig. 1, a kind of bolt with sealing function of the utility model, including turn a 2, driving screw 1, connecting screw rod 3,
Auxiliary threaded rod 4, elastic seal ring 5, one end of the driving screw 1 is fixed with and turns 2, and the other end of driving screw 1 is fixed with connection spiral shell
There is screwed hole 40 at bar 3, the middle part of the auxiliary threaded rod 4, and connecting screw rod 3 is screwed on screwed hole 40, the driving screw 1 and auxiliary threaded rod
External screw thread 10 is equipped with 4, the elastic seal ring 5 is located in the gap between driving screw 1 and auxiliary threaded rod 4, described to turn
2, driving screw 1 and connecting screw rod 3 are integral type structure, and driving screw 1 is identical with the direction of rotation of connecting screw rod 3, the elasticity
The external diameter in an initial condition of sealing ring 5 is less than the external diameter of driving screw 1, and the external diameter of driving screw 1 is identical with the external diameter of auxiliary threaded rod 4, institute
State the length of the length less than screwed hole 40 of connecting screw rod 3.
Utility model works process：
A kind of bolt with sealing function of the utility model in the course of the work, driving screw 1 can with turn to auxiliary spiral shell
Bar 4 is close, and elastic seal ring 5 is squeezed and expand laterally so that elastic seal ring 5 closely connects with the screw wall of installation bolt
Touch, form good sealing, prevent liquid etc. from flowing out from screw, also there is sealing well while ensure that and be connected firmly
Property, and elastic seal ring 5 is not exposed to outside, and elastic seal ring 5 is protected to a certain extent.
Above-described embodiment be to explanation of the present utility model, be not to restriction of the present utility model, it is any new to this practicality
Scheme after type simple transformation belongs to protection domain of the present utility model.
