製造コストを高くする原因にもなる。As can be seen in the pipe ends 1 and 10 shown in FIGS. 5 and 6 as prior art,
The pipe end of each part that constitutes the refrigeration cycle of the air conditioner is given a specific connection part shape that fits the pipe ends of the other parts connected to it, but the shape of the connection part is common. There cannot be one type, and at least two types, a male type and a female type, always exist even when the shapes of the connecting portions are unified. Since there are at least two types of connection shape at the end of the pipe,
Conventionally, it has been necessary to prepare two or more types of hermetic plugs according to the shapes of the connecting portions.
Although the stoppers 6 or 17 are discarded after the piping of the air conditioner is finished, since many of them have a relatively complicated shape, a molding die for manufacturing them by injection molding or the like is expensive. In addition, managing or selectively using various kinds of hermetic plugs in the manufacturing process of air conditioner parts causes not only the hermetic plugs but also the manufacturing cost of the air conditioner itself to increase.

Not only can it be used in common for a plurality of pipe ends having different shapes, but also the surface of the member on which the openings of those pipe ends and the joint surfaces of the screws and the connection parts are formed. The aim is to provide a closure which can even be coated at the same time to protect them.

An upper closed disc portion, a lower cylindrical portion which is connected to the closed disc portion and covers the outer periphery of the joint surface of the pipe end portion, and a connecting portion between the closed disc portion and the cylindrical portion. An annular cap portion that projects outward from the vicinity, a locking claw portion that projects inward from an intermediate position of the cylindrical portion, and an annular protrusion that projects outward from the lower end of the cylindrical portion. Provided is a hermetic plug for air conditioner piping, which includes a locking claw portion.

って保護する。When a single sealed plug is to be commonly used for a plurality of pipe ends having different shapes, for example, a male-shaped pipe end and a female-shaped pipe end, the sealed plug must first be a male-shaped plug. The cylindrical portion of the hermetically sealed plug is fitted to and protects the joint surface on the outer periphery of the male connection portion of the pipe end portion, and the closing disc portion closes the opening portion of the pipe end portion. Then, the locking claw portion that protrudes inward from the intermediate position of the cylindrical portion engages with the annular groove for the O-ring formed on the outer circumference of the pipe end portion, etc., and acts as a retainer, and at the same time, the cylindrical portion. A section covers the annular groove and the O-rings pre-mounted on it to protect them. Further, the annular claw portion at the lower end of the cylindrical portion covers and protects the base end surface of the pipe end portion.

うな、前記の場合とは異なった作用もする。When the same stopper according to the present invention is applied to the female pipe end, the cylindrical portion fits over the joint surface at the tip of the pipe end and covers it, and the closed disk portion is attached to the pipe end. To close the opening of the cylindrical portion, to engage the locking claw portion at the intermediate position of the cylindrical portion with the annular groove for O-ring formed in the female connection portion of the pipe end, Covering the O-ring annular groove is substantially the same as the action on the male end of the pipe, but in this case, the annular cap portion formed above is a concave portion which is a female connecting portion. The cylindrical claw at the lower end of the cylindrical part engages with the female screw part of the union nut near the bottom of the recess to strengthen the stopper function of the stopper itself, and also to connect the union nut to the pipe end. It also works differently from the above case, such as fixing to.

Since it has a structure, conventionally, as shown in FIG. 5, it is necessary to use a female-type hermetic plug 6, and a pipe end portion 1 for a block having a male-type connecting portion 3 or as shown in FIG. 3 and FIG. 3 also for pipe ends that are quite different in comparison, such as the pipe end 10 for a pipe member having a female connection 11 that required the use of a male closure 17. As shown in FIG. 4, they can be commonly used without any trouble. In order to facilitate comparison between the conventional example and the embodiment of the present invention, FIG.
Shows the case where the sealing plug 23 is applied to the same pipe end 1 as the conventional example shown in FIG. 5, and FIG. 4 applies the sealing plug 23 to the same pipe end 10 as the conventional example shown in FIG. Since the case is shown, the pipe ends 1 and 10 shown in FIGS.

Sealing plug 2 of the illustrated embodiment at a pipe end 1 for a block having
3 is applied, the small-diameter cylindrical portion 26 of the hermetic plug 23 is fitted to the outer periphery of the male connecting portion 3 to protect the joint surface, and the disc portion 25 opens the pipe end portion 1 of the block. The part 2 is closed to prevent foreign matter from entering. Further, the annular claw portion 31 of the sealing plug 23 is seated on the base end surface 5 of the pipe end portion 1 to prevent the surface thereof from being scratched or soiled, and the large diameter cylindrical portion 2
8 covers the annular groove 4 of the pipe end 1 and protects an O-ring (not shown) even if it is pre-mounted. The stopper 23 is prevented from coming off by engaging the claw portion 30 with the upper edge portion of the annular groove 4. Although the hermetic plug 23 is not provided with a portion that covers the bolt hole 9, the bolt hole 9 is merely inserted with a bolt (not shown), and therefore it is not particularly necessary to protect the bolt hole 9 with the hermetic plug 23. The disengagement is sufficiently achieved by the engagement of the claw portion 30 with the annular groove 4 and the fitting of the small-diameter cylindrical portion 26 on the outer circumference of the male connecting portion 3.

This is different from the case of FIG. 3 because the target is different. That is, the small-diameter cylindrical portion 26 of the hermetic stopper 23 is connected to the pipe end portion 10.
By fitting the outer periphery of the tip 12 of the above, the disc surface 25 closes the opening 18 while the joint surface of the tip 12 is protected, and the claw 30 engages with the upper edge of the annular groove 16. Although it does not come off as a stopper, it is almost the same as the case of FIG.
The concave portion serving as the female connection portion 11 of 0 is covered to prevent foreign matter from entering and protect the female screw portion 14 and the like of the union nut 15. When the O-ring is mounted in the annular groove 16 in advance, it is protected not only by the large-diameter cylindrical portion 28 of the hermetic plug 23 but also by the annular cap portion 29 so as to be overlapped. Further, the ring-shaped claw portion 31 of the hermetic stopper 23 is connected to the female screw portion 14 of the union nut 15.
When a ring groove is specially formed on a part of the inner peripheral surface or the inner peripheral surface of the lower part of the inner ring, the union nut 15 and the sealing plug 23 are fixed by engaging with the groove, and the union nut 15 is prevented from freely moving. . When the annular claw portion 31 is not engaged with the female screw portion 14 or the like, the tip of the claw portion 31 is elastically deformed to some extent and frictionally engages with a part of the inner surface of the union nut 15. And the stopper 23 are fixed.

It is possible to obtain a protective effect that is substantially the same as that of many kinds of stoppers. Therefore, since it is possible to reduce the types of sealing plugs to be prepared in the air conditioner manufacturing process, the cost of the molding die for manufacturing the sealing cap is reduced, the management of the sealing plug in the manufacturing process of the air conditioner is facilitated, and the air conditioner as a whole is cooled. Manufacturing cost can be reduced.
