[specific embodiment]
Below in conjunction with accompanying drawing, specific embodiments of the invention is described in detail.
Fig. 1 is a sealing ring and use ring structure sketch map in the preferred embodiment of sealing circle among the embodiment.Fig. 2 is the ring structure cutaway view vertically among Fig. 1.
In conjunction with Fig. 1 and Fig. 2, sealing circle 100 adopts the rubber material, and cross section vertically is the wedge shape that the middle part connects, and it comprises trunk portion 110 and axially draws the round platform portion 120 of extending by trunk portion 110 1 ends in along it.Trunk portion 110 all connects with round platform portion 120 middle parts, forms the inner peripheral surface 130 of sealing ring 100.Trunk portion 110 outer circumference surfaces cave in and form ring-like groove 140.Among this embodiment, groove 140 cross section vertically is a rectangle, and the inner peripheral surface 130 of sealing ring 100 and the bottom surface 141 of groove 140 are two sealing surfaces of sealing circle 100.
Fig. 3 is the scheme of installation of sealing ring in light fixture among the embodiment.Fig. 4 is the installation cutaway view of sealing ring in light fixture among the embodiment.Fig. 5 is a lamp outer casing structure cutaway view among the embodiment.In conjunction with Fig. 1 and Fig. 5, sealing ring 100 is installed between cable 200 and the lamp outer casing 300 when assembling.Lamp outer casing 300 is provided with the seal groove 310 that holds sealing ring 100.Seal groove 310 and sealing ring 100 shape adaptation, perforation lamp outer casing 300 and seal groove 310 cell walls middle part evagination form the annular seal plate 311 with groove 140 couplings.
When 100 pairs of cables of sealing ring 200 sealed with lamp outer casing 300, sealing ring 100 was located in the seal groove 310 and sealing plate 311 snaps in the groove 140, and cable 200 passes sealing ring 100 and arrives lamp interior.The lateral surface of cable 200 closely contacts with the inner peripheral surface 130 of sealing ring 100 and exerts pressure, and the inner peripheral surface 130 of sealing ring 100 receives the pressure of radial dilatation, and sealing ring 100 is radially expanded.The inner peripheral surface 3111 of sealing plate 311 closely contacts and applies resistance with 141 beginnings of the bottom surface of groove 140; Stop sealing ring 100 radially to continue expansion; Under cable 200 and sealing plate 311 actings in conjunction, reach the stable equilibrium at last, thereby realize stabilized seals in the bottom surface 141 of inner peripheral surface 130 and groove 140.Sealing circle 100 is realized stabilized seal on two sealing surfaces, sealing is pressed evenly, favorable sealing property, and barrier propterty is stable, has good sealing effectiveness, can effectively carry out water proof and dust proof, and light fixture is well protected.Simultaneously; When the bottom surface 141 of 3111 pairs of grooves 140 of inner peripheral surface of sealing plate 311 applies resistance; Groove 140 cross sections are rectangle, and contraction clip under drag effect tight shrouding 311 in its two sides makes sealing ring 100 be stably fixed on the lamp outer casing 300; The difficult twisting further guaranteed sealing property.Round platform portion 120 diameters are less, when sealing ring 100 is installed on seal groove 310, passes seal groove 310 easily and are convenient to sealing plate 311 and snap in the groove 140, and are easy to assembly quick.
In other embodiments, groove 140 also can be less trapezoidal of openend diameter along the cross section of axis.
In addition, a kind of light fixture that uses above-mentioned sealing ring is provided.
The light fixture of above-mentioned sealing ring and use sealing circle, the trunk portion outer circumference surface formation groove that caves in, the trunk portion middle part connects the inner peripheral surface that forms sealing ring, and the bottom surface of inner peripheral surface, groove is two sealing surfaces of sealing ring; In the junction of cable and shell, two sealing surfaces are applied external force respectively, and the two sides is stressed; Sealing is pressed evenly, favorable sealing property, and barrier propterty is stable; Thereby play good sealing effectiveness, effectively carry out water proof and dust proof, light fixture is well protected.
The above embodiment has only expressed several kinds of embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, 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 accompanying claims.
