Description

Closing cap for flexible hose connector The present invention relates to a finishing cap for a flexible hose connector, and more specifically, to a finishing cap for a flexible hose connector that enables the finishing work of a pipe connector to be performed more efficiently. Generally, to inspect for abnormalities in piping systems, regular hydrostatic pressure tests are conducted, and during these tests, it is necessary to seal the ends of the pipes. At this time, in the conventional technology, to facilitate the connection of the flexible hose and prevent detachment, the flexible hose is connected to the connection part of a connector that is barbed in a wedge shape with a tip end that gradually decreases in diameter toward one side, and then the hose clamp is bolted to each connection part. However, the clamping work for connecting these flexible hoses required a lot of time and labor, which reduced work efficiency, and there was a problem of leakage at the clamp connection part due to water pressure. FIG. 1 is an exploded perspective view of a finishing cap for a connector according to one embodiment of the present invention. FIG. 2 is an exploded cross-sectional view of the end cap of the present invention. FIG. 3 is an enlarged view of the external appearance of a fixture component in the present invention. FIG. 4 is a cross-sectional view of a fixture component in the present invention. FIG. 5 is a cross-sectional view of the assembly and installation state of the end cap of the present invention. FIG. 6 is an enlarged cross-sectional view of a fixture contact bar component according to another embodiment of the present invention. Hereinafter, specific embodiments of the present invention will be examined in detail with reference to the attached drawings. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. These embodiments are provided to more fully explain the present invention to those with average knowledge in the art. Accordingly, the shapes of components depicted in the drawings may be exaggerated to emphasize clearer explanations. It should be noted that identical components in each drawing may be illustrated with the same reference numeral. Furthermore, detailed descriptions of functions and configurations of known technology that are deemed to unnecessarily obscure the essence of the invention may be omitted. First, the configuration of a finishing cap for a flexible hose connector according to one embodiment of the present invention is as follows through FIGS. 1 to 5. In this embodiment, the end cap is fastened to a flexible hose connector (40) having a wedge-shaped outer surface at the tip, and is provided with a pair of two semi-cylindrical fixing members (first fixing member, second fixing member) to surround the tip of the connector (40), wherein a plurality of protrusions (11) are formed protruding at regular intervals on the inner surface and male screw threads (12) are formed on the outer surface, and a socket (20) into which one end (21) is inserted into the connector (40), and a cylindrical fixing cap (30) having female screw threads (32) formed on the inner surface so that the socket (20) can be fixed to the fixing member (10) while pressing the connector (40) together, is formed in an assembly structure. At this time, one of the two fixing members (10) that form a pair (first fixing member) is provided with a metal contact bar (14) fixed by a piece (15) to improve the adhesion of the contact part where mutual contact is made. Additionally, the socket (20) is provided with a stopper (22) in the middle, and the other end (23) is connected to a drain valve (50) having a flow path opening and closing function by passing through a fixing cap (30). Meanwhile, it can be seen that the above-mentioned fixing cap (30) has a through hole (31) formed so that the other end (23) of the socket (20) can pass through it. In the drawing, unexplained reference numeral 13 represents a handle part that has been knurled to prevent slipping during the assembly process, and 24 represents an O-ring to enhance watertightness of the gap. Let us examine the effects of the installation of the end cap for the flexible hose connector of the present invention, which has such a configuration. In this embodiment, the end cap is installed on the connector (40) to which the flexible hose (not shown) was connected when performing a hydrostatic pressure test of the piping system, and the assembly and installation of the end cap structure of the present invention is performed after removing the flexible hose. That is, at this time, the fixing member (10), which has two split structures, is positioned to surround the barbed processing part of the connector (40), and one end of the socket (20) is fitted into the tip of the connector (40).
