Embodiment
Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Referring to Fig. 1, an embodiment of seal arrangement of the present utility model is proposed, wherein Fig. 1 is seal arrangement one embodiment's of the present utility model fractionation structural representation.The seal arrangement of present embodiment comprises fore shell 100, back cover 200 and seal ring 300, convex with the first atrium 110 on the described fore shell 100, convex with the second atrium 210 on the described back cover 200, described the first atrium 110 inwalls are provided with internal thread 111, described the second atrium 210 outer walls are provided with the outside thread 211 adaptive with this internal thread 111, described seal ring 300 places described the first atrium 110 inside bottom, described the first atrium 110 and the second atrium 210 screw rear press seal circle 300 by screw thread, form a sealed cavity.The seal arrangement of present embodiment can be used for various waterproof products, and the sealing device both can be wholely set with the housing of waterproof product, also can first the element that needs waterproof be installed on seal arrangement after, again the sealing device is fixed on the housing of waterproof product.Fore shell 100 and the back cover 200 of the seal arrangement of present embodiment are threaded connection, and do not need rigging screw, and assembling and dismounting are all very convenient quick.During assembling, first seal ring 300 is placed fore shell 100 first atriums 110 inside bottom, seal ring 300 external diameter sizes are just to fit into suitable with the first atrium 110 inwalls, seal ring 300 is selected the material with preferably elastic strain ability, usually select plastic tube, such as silica gel ring, rubber ring etc.Then will need the element of waterproof to be installed in the second atrium 210 of back cover 200, then the outside thread 211 of the internal thread 111 on fore shell 100 first atriums 110 being aimed on back cover 200 second atriums 210, then rotate back cover 200, so that first atrium 110 inner screw in of the second atrium 210 of back cover 200 along screw thread toward fore shell 100.When the end of back cover 200 second atriums 210 props up seal ring 300, continue firmly to screw in inward, so that resiliently deformable occurs seal ring 300, until can not screw in.At this moment, the second atrium 210 of back cover 200 enters first atrium interior 110 of fore shell 100 fully, and the end of the second atrium 210 is tightly pushed, butt the seal ring 300 that resiliently deformable has occured, thereby so that the first atrium 110, the second atrium 210 and seal ring 300 have formed a sealed cavity jointly, outside water can not enter in the sealing cavity.Seal arrangement after the assembling as shown in Figure 2.During dismounting, only need the second atrium 210 reverse back-out from the first atrium 110 got final product.In addition, also seal ring 300 can be placed the bottom in back cover 200 second atriums 210 outsides, the internal diameter size of sealing circle 300 fits into suitable with lucky outer wall with the second atrium 210, after the second atrium 210 screws in the first atrium 110, seal ring 300 butts of the end of the first atrium 110 and the second atrium 210 exterior bottom, continue this moment to revolve inward, so that resiliently deformable occurs in seal ring 300, until can not screw in, final so that the first atrium 110, the second atrium 210 and seal ring 300 have formed a sealed cavity jointly.Certainly, also can seal ring 300 all be set in the first atrium 110 inside bottom and the second atrium 210 exterior bottom, so that its sealing effect reaches best.Therefore the sealing device structure of present embodiment is simple, has saved a large amount of screw assembly processes, has improved manufacturing efficiency, has saved cost, and good water-proof effect, easy disassembly.
Further, referring to Fig. 3, Fig. 4, Fig. 3, Fig. 4 all be Fig. 2 along the sectional view of A-A line, just wherein do not have the fitting tight circle in the sectional view of Fig. 3, assembled seal ring in the sectional view of Fig. 4.In order further to improve waterproofing effect, establish the first groove 120 of an accommodating seal ring 300 in the first atrium 110 inside bottom of above-described embodiment, the degree of depth of this groove 120 is to be advisable less than the height of seal ring 300, so that seal ring 300 protrudes a part outside the first groove 120.Seal ring 300 places the first groove 120, position that on the one hand can fixed seal ring 300 prevents that it from moving and affect sealing effect, can limit its radial deformation on the other hand so that the end of the second atrium 210 and seal ring 300 butts get more tight closely, increase sealing effect.Equally, also can establish in the second atrium 210 exterior bottom the second groove 220 of an accommodating seal ring 300 so that during the end crush seal circle 300 of the first atrium 110, sealing circle 300 can not move and so that their butts get more tight closely.Certainly, also can groove all be set in the first atrium 110 inside bottom and the second atrium 210 exterior bottom, so that sealing effect is better.
The further improvement of sealing device is proposed further.The second adaptive bulge loop 212 of corresponding setting and described the first groove 120 in the second atrium 210 ends of above-described embodiment.After being provided with the second bulge loop 212, seal ring 300 can be placed in fully in the first groove 120 and need not to protrude a part outside the first groove 120, so that seal ring 300 is fixed more firmly.When the first atrium 110 and the second atrium 210 screw by screw thread, the second bulge loop 212 enters the first groove 120 and butt crush seal circle 300, because seal ring 300 is fixed in the first groove 120 and can't moves, and its radial deformation also is restricted, thereby so that the second bulge loop 212 and seal ring 300 butts get more tight closely, sealing effect is able to further raising.As being equal to replacement, the first bulge loop 112 that also can be in the first atrium 110 ends corresponding setting and described the second groove 220 are adaptive, equally after the first bulge loop 112 enters the second groove 220, itself and seal ring 300 butts get more tight closely.Certainly, when the second bulge loop 212 also can be set in the end of the second atrium 210, the first bulge loop 112 is set in the end of the first atrium 110 also, realizing the effect of double seal, thereby so that the sealing effect of seal arrangement reaches the optimum state.
Should be understood that; it below only is preferred embodiment of the present utility model; can not therefore limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
