Abstract
The utility model discloses a kind of locking sealing screws, sealing ring is fixed by the way that sealing ring fixing groove is arranged in screw rod periphery, solve the problems, such as sealing ring sealing in the prior art, it is further locking by the way that spring washer realization is arranged in sealing ring fixing groove periphery simultaneously, to achieve the effect that locking sealing, the utility model is simple in structure, of low cost, it is highly practical, have good market prospects.
Description
Technical field
The utility model is related to machanical fastener fields, and in particular to a kind of locking sealing screw.
Background technology
Screw is a kind of common fastener, is widely used on machinery, electric appliance and building.For the sealing at fastening
Property, there is a different requirements in different fields, and way used by the prior art is that one is added between screw and fastening means
Layer sealing ring, such way can solve the problems, such as leakproofness to a certain extent, but over time, and sealing ring is in screw and tightly
Gu being easy to loosen under the extruding of device, to cause to form gap between screw and fastening means, its leakproofness is damaged.
Utility model content
The purpose of the utility model is to overcome deficiencies in the prior art, provide a kind of locking sealing screw.
To solve prior art problem, the utility model discloses a kind of locking sealing screw, including screw and seal close
Seal further includes sealing ring fixing groove, and sealing ring fixing groove is arranged in the periphery of the threaded shank of screw, and sealing sealing ring setting exists
In sealing ring fixing groove, sealing ring fixing groove can fix sealing sealing ring, and the height for sealing sealing ring is fixed higher than sealing ring
Slot.
Further, sealing sealing ring is made of elastic material.
Further, further include spring washer, spring washer is arranged in the periphery of sealing ring fixing groove.
Further, it is arranged in spring washer jagged.
Further, it is made of elastic material.
Further, the thickness of spring washer is less than the height of sealing ring fixing groove.
Further, it is provided with hexagonal recess at the top of screw.
The utility model has the advantage that：Sealing sealing ring is fixed by the way that sealing ring fixing groove is arranged, is prevented
It is loosened, and is further ensured that its leakproofness by the way that spring washer is arranged, duplicate protection is realized together with sealing ring.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model part-structure schematic diagram；
Fig. 3 is the side view of the utility model；
Fig. 4 is the utility model schematical top view.
Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and the scope of protection of the utility model cannot be limited with this.
As shown in Figs. 1-3, a kind of locking sealing screw of the utility model, the periphery of the threaded shank of screw 1 are provided with close
Seal fixing groove 3, sealing ring 2 are arranged in sealing ring fixing groove 3, and sealing ring fixing groove 3 can fix sealing sealing ring 2, close
The height of seal 2 is higher than sealing ring fixing groove 3, and sealing ring 2 is made of elastic material, when screw 1 is screwed into fastening means, spiral shell
Nail 1 forms sealing sealing ring 2 with fastening means and squeezes, and sealing ring 2 fills up in sealing ring fixing groove 3, to the shape at fastening
At sealing, while being not easy to loosen.
The periphery of sealing ring fixing groove 3 is additionally provided with spring washer 4, and spring washer can be used elastic material and be made, and the thickness of spring washer 4 is low
In the height of sealing ring fixing groove 3.Screw 1, which is screwed into fastening means crush seal sealing ring 2, makes its deformation, to sealing ring fixing groove
Filling in 3, until the top of sealing ring fixing groove 3 contacts fastening means, simultaneously spring washer 4 also begins to flexible deformation, to
Formed the dual-seal of sealing ring 2 and spring washer 4 with it is locking.Jagged, fast and easy installation spring washer is set in spring washer 4, while
It is suitable for the screw of different bores.
As shown in figure 4, being provided with hexagonal recess at the top of screw, engaging tool is facilitated to act screw implementation.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
The scope of protection of the utility model is also should be regarded as into deformation.
