Embodiment
For the ease of understanding the present invention, below with reference to relevant drawings, the present invention is described more fully.Preferred embodiment of the present invention is given in accompanying drawing.But the present invention can realize in many different forms, is not limited to embodiment described herein.On the contrary, provide the object of these embodiments be make the understanding of disclosure of the present invention more comprehensively thorough.
It should be noted that, when element is called as " being fixed on " another element, directly can there is element placed in the middle in it on another element or also.When an element is considered to " connection " another element, it can be directly connected to another element or may there is centering elements simultaneously.
Unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present invention understand usually.The object of term used in the description of the invention herein just in order to describe specific embodiment, is not intended to be restriction the present invention.Term as used herein " and/or " comprise arbitrary and all combinations of one or more relevant Listed Items.
As shown in Figure 1, the sealing configuration 100 of the cylindrical shell that is threaded of a mode of execution comprises the first cylindrical shell 110, second cylindrical shell 120 and seal ring 130.
Incorporated by reference to Fig. 2, the first cylindrical shell 110 is hollow cylindrical shape.First cylindrical shell 110 inner circle wall is at one end provided with internal thread 112.Internal thread 112 has certain length, to make mounted configuration firm.In the present embodiment, the first cylindrical shell 110 is provided with boss 114 at the periphery wall of the one end being provided with internal thread 112.Boss 114 is the ring structure around the first cylindrical shell 110.Offer breach in boss 114, the containing groove 116 of a ring-type thus the periphery wall of boss 114 and the first cylindrical shell 110 is encircled a city, also namely a sidewall of containing groove 116 is the periphery wall of the first cylindrical shell 110, and another sidewall is boss 114.The periphery wall of the first cylindrical shell 110 arranges boss, the wall thickness of the first cylindrical shell 110 in this end can be increased, thus increase the installation strength of the first cylindrical shell 110 in end.
Further, in the present embodiment, the outer side wall formed by boss 114 of containing groove 110 protrudes from the end of the first cylindrical shell 110, and this outer side wall is provided with 2 grades of ledge structures 118.The lowermost level step surface of 2 grades of ledge structures 118 is parallel with the end of the first cylindrical shell 110.
Be appreciated that in other embodiments, the shape of the first cylindrical shell 110 is not limited to above-mentioned hollow cylindrical shape, as long as be cylindrical body at the position arranging internal thread 112; It is inner that containing groove 116 both directly can be opened in boss 114, and also namely two sidewalls of containing groove 116 are formed by boss 114.In addition, the ledge structure 118 on boss 114 is not limited to 2 grades, as can also for be arrangeding in parallel with the end of the first cylindrical shell 110 or 3 grades, 4 grades of steps etc.
Please refer to the drawing 3, in the present embodiment the second cylindrical shell 120 to comprise bottom cylinder 122, edge portion 124 and trunk portion 126.
Cylinder bottom 122 comprises flat plat part 222 and along the outward-dipping rake 224 extended to form of plat part 222 periphery.Arrange rake 224 can so that when outdoor application the foreign material such as rainwater 122 flow down and to be unlikely to remain in a large number bottom cylinder 122 and cause extra load bottom cylinder.Be appreciated that in other embodiments, bottom cylinder, the shape of 122 is not limited thereto, as can also be directly a flat board etc.
Edge portion 124 be bottom cylinder 122 periphery to stretch out formation, specifically in the present embodiment, be to stretch out formation along the periphery of rake 224.Edge portion 124 is the sheet structure of annular.In the present embodiment, a side surface in edge portion 124 is provided with protruding 242.Projection 242 is located at the opening direction side of bottom cylinder 122.The thickness of protruding 242 is consistent with the internal diameter of containing groove 116 thus can insert in containing groove 116.Further, in the present embodiment, edge portion 124 outside protruding 242 is provided with the ledge structure 244 with ledge structure 118 adaptation on boss 114, and the ledge structure 244 also namely in edge portion 124 can fit like a glove with the ledge structure 118 on boss 114 to be formed and seal.
Trunk portion 126 to be located at bottom cylinder 122 with the position, boundary in edge portion 124.In the present embodiment, trunk portion 126 is hollow cylindrical shape, and trunk portion 126 is vertical with edge portion 124 arranges.The outer wall of trunk portion 126 is provided with outside thread 262.First cylindrical shell 110 is threaded with the second cylindrical shell 120 with internal thread 112 adaptation by outside thread 262.
Seal ring 130 is elastic material making.Seal ring 130 is the column structure of ring-type.The thickness of seal ring 130 is consistent with the internal diameter of containing groove 116 or slightly larger than the internal diameter of containing groove 116.The height of seal ring 130 is consistent with the degree of depth of containing groove 116 or be slightly less than the degree of depth of containing groove 116.
During installation, first seal ring 130 is snapped in containing groove 116, then the first cylindrical shell 110 is threaded with the second cylindrical shell, after screwing screw thread, projection 242 can stretch in containing groove 116 and abut with seal ring 130 elasticity, and the ledge structure 244 simultaneously in edge portion 124 fits like a glove to be formed with the ledge structure 118 on boss 114 and seals, thus forms multi-stage stairs sealing configuration in the outside of screw connection point, moisture not easily flows into the inside of the first cylindrical shell 110, and sealability is excellent.
The sealing configuration 100 of the above-mentioned cylindrical shell that is threaded can be applied in field of light fittings as Cap casing, has good water proof and dust proof effect.
The sealing configuration 100 of this cylindrical shell that is threaded arranges the boss 114 offering containing groove 116 by the periphery wall in first cylindrical shell 110 one end, seal ring 130 is placed in the containing groove 116 of boss 114, and the second cylindrical shell 120 is provided with edge portion 124 and arrange the projection 242 that can abut with seal ring 130 at a side surface in edge portion 124, thus formed between protruding 242 and seal ring 130 and seal, can effectively prevent moisture from entering, and seal ring 130 is positioned at outside the periphery wall of the first cylindrical shell 110, different near traditional tool withdrawal groove being located at worm structure, easy for installation, seal ring difficult drop-off or be stuck in screw thread.
The above embodiment only have expressed several mode of execution of the present invention, and it describes comparatively 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 the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
