Unless otherwise defined, all of technology used herein and scientific terminology and the technology belonging to the present invention
The implication that the technical staff in field is generally understood that is identical.The art used the most in the description of the invention
Language is intended merely to describe the purpose of specific embodiment, it is not intended that in limiting the present invention.Used herein
Term " and/or " include the arbitrary and all of combination of one or more relevant Listed Items.
As it is shown in figure 1, the sealing structure 100 of the threaded cylinder of an embodiment include the first cylinder 110,
Second cylinder 120 and sealing ring 130.
Incorporated by reference to Fig. 2, the first cylinder 110 is hollow cylindrical shape.First cylinder 110 at one end interior
Perisporium is provided with internal thread 112.Internal thread 112 has certain length, so that mounted configuration is firm.At this
In embodiment, first cylinder 110 periphery wall in the one end being provided with internal thread 112 is provided with boss 114.Convex
Platform 114 is the circulus around the first cylinder 110.Boss 114 offers breach, thus boss 114
Encircle a city a ring-type storage tank 116 with the periphery wall of the first cylinder 110, namely a sidewall of storage tank 116 is
The periphery wall of the first cylinder 110, another sidewall is boss 114.The periphery wall of the first cylinder 110 is arranged
Boss, can increase by first cylinder 110 wall thickness in this end, thus increase by the first cylinder 110 in end
Installation strength.
Further, in the present embodiment, boss 114 lateral wall formed of storage tank 110 protrudes from
The end of the first cylinder 110, and this lateral wall is provided with 2 grades of ledge structures 118.2 grades of ledge structures 118
Lowermost level step surface parallel with the end of the first cylinder 110.
Being appreciated that in other embodiments, the shape of the first cylinder 110 is not limited to above-mentioned hollow circle
Cylinder body shape, as long as being cylinder at the position arranging internal thread 112；Storage tank 116 both can be straight
Connect and be opened in boss 114 inside, namely two sidewalls of storage tank 116 are constituted by boss 114.Additionally,
Ledge structure 118 on boss 114 is not limited to 2 grades, as can also be parallel with the end of the first cylinder 110
Arrange or 3 grades, 4 grades of steps etc..
Please join Fig. 3, the second cylinder 120 includes 122, edge portion 124 and post bottom cylinder in the present embodiment
Body 126.
Bottom Tong, 122 include flat flat part 222 and along the flat part 222 outward-dipping extension of periphery
The rake 224 formed.Arranging rake 224 can be so that the foreign material such as rainwater be bottom cylinder when outdoor application
122 flow down and are unlikely to remain in a large number bottom cylinder on 122 and cause extra load.It is appreciated that at other
In embodiment, bottom cylinder, the shape of 122 is not limited to this, as can also be directly a flat board etc..
Edge portion 124 is that the periphery of 122 stretches out formation bottom cylinder, the most in the present embodiment,
It is to stretch out formation along the periphery of rake 224.Edge portion 124 is the laminated structure of annular.In this reality
Executing in mode, a side surface in edge portion 124 is provided with protruding 242.Protruding 242 are located at bottom cylinder 122 open
Mouth side, direction.The thickness of protruding 242 is consistent with the internal diameter of storage tank 116 thus can be inserted into storage tank 116
In.Further, in the present embodiment, the edge portion 124 outside protruding 242 be provided with on boss 114
The ledge structure 244 of ledge structure 118 adaptation, namely the ledge structure 244 in edge portion 124 can be with
Ledge structure 118 on boss 114 fits like a glove to be formed and seals.
Trunk portion 126 is located at bottom cylinder the position, boundary of 122 and edge portion 124.In the present embodiment,
Trunk portion 126 is hollow cylindrical shape, and trunk portion 126 is vertically arranged with edge portion 124.Cylinder
The outer wall in portion 126 is provided with external screw thread 262.External screw thread 262 and internal thread 112 adaptation by the first cylinder 110 with
Second cylinder 120 is threaded.
Sealing ring 130 makes for elastomeric material.Sealing ring 130 is ring-type column structure.Sealing ring 130
Thickness consistent with the internal diameter of storage tank 116 or slightly larger than the internal diameter of storage tank 116.The height of sealing ring 130
Spend the degree of depth that is consistent with the degree of depth of storage tank 116 or that be slightly less than storage tank 116.
During installation, first sealing ring 130 is snapped in storage tank 116, then by the first cylinder 110 and
Two cylinders carry out threaded, after screwing screw thread, protruding 242 can stretch in storage tank 116 with sealing ring
130 elastic abuttings, the simultaneously ledge structure 244 in edge portion 124 and the ledge structure 118 on boss 114
The formation that fits like a glove seals, thus forms multi-stage stairs sealing structure, moisture the outside of screw connection point
Being difficult to flow into the inside of the first cylinder 110, sealing property is excellent.
The sealing structure 100 of above-mentioned threaded cylinder can be applied in field of light fittings as Cap casing, has
Preferably water proof and dust proof effect.
The sealing structure 100 of this threaded cylinder is arranged by the periphery wall in first cylinder 110 one end and opens
Being provided with the boss 114 of storage tank 116, sealing ring 130 is placed in the storage tank 116 of boss 114, and second
Cylinder 120 is provided with edge portion 124 and the side surface configuration in edge portion 124 can abut with sealing ring 130
Projection 242, thus formed between protruding 242 and sealing ring 130 and seal, can effectively prevent moisture from entering,
And sealing ring 130 is in outside the periphery wall of the first cylinder 110, is located at moving back of helicitic texture with traditional
Near cutter groove different, easy for installation, sealing ring difficult drop-off or be stuck in screw thread.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that, for this area
Those of ordinary skill for, without departing from the inventive concept of the premise, it is also possible to make some deformation and
Improving, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be with appended
Claim is as the criterion.
