Embodiment
Contrast accompanying drawing below, by the description to optimum embodiment, embodiment of the present utility model is described in further detail.
As Figure 1-Figure 5, this air-conditioning connection pipe for internal-external unit sealing plug, comprise elastic cylinder 1, on elastic cylinder 1 and connecting tube, set nut 6 matches, elastic cylinder 1 is provided with location rib 2 and the set positioning groove of nut 6 inwall matches, nut 6 external structures are identical with copper nut in prior art, but no longer machining screw of nut 6 inwalls, but circular groove or curve bath that processing and location rib 2 coordinate; Or as another kind of scheme, elastic cylinder 1 is provided with locating slot and the set positioning bar of nut 6 inwalls matches, same nut 6 external structures are identical with copper nut in prior art, no longer machining screw of nut 6 inwalls, but circular orientation muscle or arc positioning bar that on processing and elastic cylinder 1, set locating slot coordinates.
Elastic cylinder 1 is aimed to nut 6 oral areas, press elastic cylinder 1, elastic cylinder 1 is once fast in pressed-in nut 6, and location rib 2 snaps on the positioning groove of nut 6 or the locating slot of elastic cylinder 1 snaps on the positioning bar of nut 6 inwalls, completes assembling; This sealing plug adopts damascene structures, once presses and can complete assembling.Locate rib 2 and positioning groove simultaneously and coordinate, or locating slot and positioning bar cooperation, can ensure the connection reliability of sealing plug and nut 6, and then ensure the functional reliability of air conditioner.Preferably sealing plug adopts the flexible glue material molding and forming such as PE.
Preferred orientation rib 2 is for being located at the annular protrusion on elastic cylinder 1 outer wall, and positioning bar is the annular protrusion that is located at nut 6 inwalls.Location rib 2 on elastic cylinder 1 is stuck on the positioning groove of nut 6 inwalls, after sealing plug assembling, realize location by location rib 2, or adopt another scheme, positioning bar on nut 6 is stuck on the locating slot on elastic cylinder 1, after sealing plug assembling, realizes location by positioning bar.Simple fast when this orientation type is not only assembled, and locating effect is better.
Annular protrusion is provided with opening slot.Opening slot is used for increasing the ductility of location rib 2 and positioning bar, further improves the elasticity of location rib 2 and positioning bar, and assembling is more prone to, and efficiency of assembling is higher.
