Embodiment
The utility model discloses a kind of connecting tube rubber plug, this is simple in structure, and assembly manipulation is convenient, and using effect is stable; Can save the operating time, enhance productivity simultaneously.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-Fig. 3, the three-dimensional structure schematic diagram of the connecting tube rubber plug that Fig. 1 provides for the utility model embodiment; The plane structure plan view of the connecting tube rubber plug that Fig. 2 provides for the utility model embodiment; Fig. 3 is the plan view of Fig. 2.
The connecting tube rubber plug that the utility model embodiment provides, is applicable to the copper nut of air-conditioning duct part connecting pipe component joint, and the center hole internal surface of copper nut is provided with connecting thread, for connecting cooperation with other joints by worm structure;
Its core improvement is, connecting tube rubber plug comprises the plug part 1 of assembling in the center hole for filling in copper nut, and above-mentioned plug part 1 has the outer peripheral surface for the inner threaded surface interference fit of same copper nut.In assembly process, firmly rubber plug is filled in union nut, itself and union nut internal surface and screw thread are closely cooperated, protection inside is not subject to extraneous damage.
Can find out from above-mentioned technological scheme, the connecting tube rubber plug that the utility model embodiment provides, simple in structure, its plug part 1 has the outer peripheral surface for the inner threaded surface interference fit of same copper nut, when production and application, can directly fill in copper nut inside, save the compound action of tightening, by restructuring and production assembly method, reduce the complexity on structural and operation task, save activity time, through facts have proved, can improve 80% manufacturing efficiency.
In order further to optimize above-mentioned technological scheme, the outer, one end that plug part 1 coordinates for same copper nut is provided with chamfering, shown in its structure can see figures.1.and.2.By this one end in plug part 1, above-mentioned chamfering structure is set, can facilitates in its center hole that enters copper nut, be more conducive to connecting tube rubber plug that this case provides and the assembly process of copper nut, improved efficiency.In this programme preferred embodiment, adopting herein specification is the chamfering of 45 °.
More than define the outer circumferential face structure of plug part 1, about its internal structure, in the specific embodiment providing at this programme, plug part 1 has the tubular structure of hollow, makes total lighter and handier, can also be convenient to take out.Certainly, about the internal structure of plug part 1, suitable adjustment can also be made according to actual conditions in related domain, such as setting up stiffening rib therein for requirement of strength, or directly adopts solid construction.
