DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a local cleaning device having a cleaning nozzle, and more particularly, to a connecting device for a water supply pipe of a toilet in the local human cleaning device.

[0002]

2. Description of the Related Art Conventionally, as shown in a perspective view of FIG.
A body part cleaning device main body 102 on the toilet device 101 is provided, and there is a body part cleaning device body 102 in which a toilet seat 103 and a toilet lid 104 are attached to be openable and closable. A water supply pipe protrudes from the side wall of the toilet. Water supplied from the water supply pipe 106 is supplied to the water supply hose 1 via a branch plug 107.
08 and the low tank connecting pipe 111 side, the tip of the water supply hose 108 is connected to the socket 109 protruding from the human body local cleaning device main body 102, and the water supply hose 10
Tap water is supplied to the human body local cleaning device main body 102 via the main body 8.

As shown in FIG. 9, a water supply hose 108 has a connecting portion 112 interposed in the branch plug portion 107, and the distal end of the connecting portion 112 is connected to the branch plug portion 107 by tightening a cap nut 110. , This cap nut 11
Packing is put in the inside of 0 to secure the sealing property. As described above, conventionally, the branch plug part 1 is
07, it is necessary to connect a water supply hose, and when tightening this cap nut 110 using a tool at the installation place in a narrow toilet, the tool cannot be turned when tightening this cap nut 110 using a tool. May be difficult. In addition, it is necessary to put packing in the cap nut 110, and the cap nut 110 is easily loosened, and there is a problem that if the cap nut 110 is loosened by receiving a stress due to the twist of the water supply hose 108, water leakage may occur. Was.

As a technique for solving this problem, the invention of Japanese Patent Application Laid-Open No. 9-12500 discloses a technique in which the connection between a branch tap and a flexible water supply hose is performed by a one-touch detachable connection device having a fitting elastic member. Is disclosed.
This technique uses a connecting device 223 as shown in FIGS.
Are connected to the fitting elastic member 2 in a bifurcated manner from the base 223a.
23b and 223b are integrally formed, and at the lower end of each fitting elastic member 223b, the engaging groove M is formed in a vertically long slot shape from the guide piece 223c extending outwardly and inclined to the fitting elastic member 223b. Are formed, and the pair of guide pieces 223c and 223c are connected to the protruding tube 219 and the connecting portion 2
12 and pressed against the connecting device 223 from above by contacting the outer periphery of the pair of fitting elastic members 223b and 223.
b spreads outward and is fitted into the outer circumference of the protruding tube 219 and the connecting portion 212. In this state, the jaws 219a and 212a are fitted into the engaging groove M, and the connecting device 223 is one-touch. The connection between the protruding tube 219 and the connecting portion 212 can be completed by attaching to the jaws 219a and 212a, and the fitting elastic member 223b is easily spread outward by pulling the quick connecting portion 223 upward. This is a technique that can be pulled out and becomes extremely easy to attach and detach.

For this reason, parts of the stopper member 230 are required, and the assemblability of the stopper member 230 and the quick connection device is not always good, which leads to an increase in cost due to the parts and assembly steps.

In general, when the quick connection device 223 disclosed in Japanese Patent Application Laid-Open No. 9-12500 is implemented, a stainless member such as SUS is used for the quick connection member 323.
Since the material of the quick connection device 223 and the material of the stopper member 230 are different, there is a possibility that the quick connection device 223 cannot be assembled due to a temperature change,
Even if assembled, play may occur, and in the worst case, the assembly member may be detached. Further, when attaching the quick member, there is a possibility that the fastening of the detaching member may be forgotten, and as a result, there is a possibility that the quick member comes off.

The present invention has solved the above-mentioned problems, and has a structure in which the number of parts is reduced, the assembling property is good, the cost is reduced, and the disconnection prevention portion of the connection device is integrally formed of resin. Due to the temperature change, there is no play at the time of assembling, and the assembling member does not come off. It is an object of the present invention to provide a water supply pipe connection structure for a toilet bowl in which there is no possibility of forgetting a detaching member itself when assembling the connection apparatus to a water supply pipe, and there is no possibility that the connection apparatus will be detached due to forgetting.
