The crane was damaged when the construction plan was about to end. In addition, the pipe fittings used for the water outlet must be inspected before the inspection process is completed. The test involves flowing water through the drain, the outlet 'until it reaches a height above the bathtub, and the tester then decides if any plumbing leaks occur. So 'At the beginning of the test operation, a plug system was placed in the beta drain of the bath rainbow' and a sealing plate was placed at the end of the bathtub above the overflow outlet . The existing overflow plate has a central opening σ therein. There are two or four small screw holes in the plate adjacent to the central opening, two of which are used to hold the plate to the piping fixture. In some cases, an accessory is present so that the screw aperture is seated directly at the towelwell of the access aperture. In this state of the towel, the hole U was made available for use in the test program at 7G per day. In any case, the test procedure usually involves filling a pouch into a tube in the wall via a large central opening and the I-piece is sealed when the pouch is inflated. Furthermore, existing sealing panels must generally be removed when decorative panels are installed. The decorative plate is typically held by two screws, which use the plate's screw opening or an opening outside the two 1224659 in the case where four holes are provided. Some efforts have been implemented to seal the overflow port of the bathtub via a diaphragm and then cut the diaphragm when testing is complete (see U.S. Patent No. 5,890,241). However, the use of a system including a diaphragm sometimes involves screws and tools, and is not always easy to install and remove after testing. [Content] Therefore, one of the main objects of the present invention is to provide a bath overflow The seal of the port port is very easy to be anxious for testing purposes and is easily made to be an operator for overflow purposes when the test is completed. A still further object of the present invention is to provide a sealing member for a bathtub overflow port, which is very economical in manufacturing. These and other purposes will be understood by those skilled in the art. -A temporary closing mechanism for a bath red overflow port π, comprising: a solid cover placed on the outer end of a discharge pipe extending through the overflow port, which is screwed To the outer end, and on its inner side: with or without a sealing member;-with a lateral surface corpus callosum, with a perforation on the lateral surface through a sealing barrier Covered, or a solid plug, screwed into the threaded interior of the outer end of the discharge pipe. The temporary closing mechanism of the mouth is an expandable non-threaded plug. It is also disclosed that a bathtub overflow port includes a 1224659 plug extending through one of the overflow port, which can be expanded during the test of the water system. In order to seal the overflow port, the system can be moved to a non-expanded state after the test has been completed for easy removal from the port. [Embodiment] As shown in the first picture and the first picture of A, a traditional bathroom structure 10 has a floor i 2 and a hollow wall 14 with a wall opening 丄 6 therein. A conventional bathtub 丄 8 series has a base 20 abutting on the floor 12. The side wall 22 extends upward from the base 20, and one end wall portion 24 also extends upward from the base 200. A bottom 2 6 series is presented in a spaced relationship from the floor 12. A traditional discharge port 28 is located in the bottom 26. A conventional overflow port 30 is located in the end wall 24 (see the second figure). A vertical discharge pipe 32 extends downward from the discharge port 28, and an overflow discharge pipe 34 extends downward from the overflow port 30. A horizontal pipe fitting 36 is connected to the pipe fittings 32 and 34. A drainage pipe 38 extends downward from the connecting part of the pipes 34 and 36. A traditional vertical ventilation pipe 40 is located in the hollow wall. The pipe 4 2 is connected to the upper end of the ventilation pipe 40 and the overflow discharge pipe ^ 4 (see the first a). The conventional water inlet pipe 4 4 ′ extends through the hollow wall portion 40 and is connected to the valve body 46, while the valve body 4 β # and 丄 D are connected to the conventional control element 48 and the faucet 5 〇 7 1224659 Referring to the second to fourth figures, a cover 5 Γ Λ ^ ^ You have an outer surface 5 4 and the outer surface 5 4 has an inner surface ^ u b6 (see the fourth image) and an outer surface 5 8.

The short pipe 7 80 'is suitable for matching with the internal section of the overflow discharge pipe 34 (see thread in figure 10) ... a O-ring seal or similar: not shown in the figure) can be used to Extending around the outer part of the short 7 'to seal the outer part of the plate 7 6 to the port 3 J In operation, the devices in the second to fourth figures are only screwed tightly by the body 5 2 It is fixed on the external thread 3 i of port 30. When the water test was completed, the cap system was removed and the conventional bath overflow device was placed on the port 30. 'The cover 5 6 6 series can be used in the fifth and sixth picture of the device 2 series can be removed from the port 30, or a thin sealing diaphragm to be cut to allow traditional overflow Attachment of institutions. With regard to the devices shown in Figures 7 and 8, when the test is completed, the 'cover 7 2 series is only removed from the opening 30 which will be discarded: this traditional overflow equipment system can be Place on thread 3 i. The plugs related to the ninth figure and the tenth figure are tightly inserted into the port 3 0 by the internal thread 8 2 in the component 3 4 A. When the water test is completed, the plug system is removed and discarded (or retained for further use), and the traditional overflow mechanism is inserted into the port. In the fifth embodiment (tenth 1 to 13), the cover 5 2 series can be exchanged with a conventional expandable plug 86. Referring to the eleventh to thirteenth drawings, a conventional expandable plug 8 6 series is shown 9 1224659. 'It does not itself include the present invention, ^ No' months, however, it is related to the present invention Use and applications are considered novel.

The circle around the port 〈8 is 100 and tightly resists the inner surface of the cicada port 3 (the internal deformation of the spring port 30; ). Around 100 hearts / brothers are shown in the thirteenth figure. The second T: 3 :, so sealed, the water test procedure can be completed. The second nut, the dish nut 106, is attached to the bolt shank 92, and it is rotated nightly to loosen the elastic collar 98. The plug 8 6 series can then be removed from the port 30 :::: a slidable way to allow a traditional cover to be placed over the port. -The present invention eliminates the threads' required in port 30 to secure the -seal plug therein, thereby saving some costs in manufacturing. In addition, the plug 86 series can be easily inserted into port 30 and removed at 0, which speeds up the water test process. Therefore, the present invention achieves its stated purpose.
