Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a device for simply and quickly connecting a case containing a valve opening/closing mechanism of a one-touch faucet to an existing faucet main body.

(Problem that the invention aims to solve) As is well known, this type of one-touch faucet can be used to turn water by simply rotating the nozzle pipe, which is connected to the lower end of the case that has a built-in valve opening/closing mechanism, from side to side. Because you can stop it once it starts, the product name is ``One Tatsuchi Shyato'' (sold by Teramachi, Itoigawa City, Niigata Prefecture).
It is widely known as Towa Electronics Industry Co., Ltd. and is very well received by users.

However, in general faucets, including this type of one-touch faucet, the nuts that connect the faucet body and the case supporting the nozzle pipe are all formed with right-handed threads to match the faucet body. Due to the fact that when performing installation work, if the nut is turned to the right, the screws on one connection will tighten and the screws on the other connection will loosen, so it is necessary to tighten the screws on either one. The screws must be strongly tightened and completely fixed before the other screw can be tightened. There was a problem that the nut often came loose, and the tightening position of the nut could not be determined no matter how long it took.

In view of the above-mentioned problems, the purpose of the present invention is to provide a one-touch plug that has the function of simultaneously tightening or loosening two screws provided at the upper and lower ends of a nut by simply rotating the nut in one direction. To provide a case connecting device with a simple structure and at low cost.

(Means for solving the problem) This invention was devised to achieve the above-mentioned purpose, and consists of a male screw at the upper end of the case and a female screw at the lower end of the nut that is screwed into the male screw. are each formed with a left-hand thread, and the female thread at the upper end of the nut is formed into a right-hand thread by matching the male thread at the lower end of the faucet body.

(Example) Hereinafter, the present invention will be described in detail with reference to drawings of examples. In the drawings, reference numeral 1 is a faucet body, 2 is a case in which a valve opening/closing mechanism of a one-touch faucet is built-in, and the case 2 is A nozzle pipe 3 is attached and fixed to the lower end of the case 2 so as to be rotatable in the horizontal direction, and a nozzle pipe 3 is attached to the upper end of the case 2.
A valve seat 5 is located at a position slightly rearwardly offset from the center line of rotation, and a valve ball 6 is housed inside the valve seat 5 so as to be able to float up and down in the vertical direction. When it rotates, the top of the slope cam 7 that was pushing up the valve ball 6 turns to the left or right and separates from the valve ball 6, and the valve ball 6 is pushed down by water pressure from the faucet body 1. Since it is in close contact with the valve seat 5, the water flow to the nozzle pipe 3 is stopped. However, when the nozzle pipe 3 is rotated to the center and returned to its original position, the valve ball 6 is moved to the top of the inclined cam 7. As shown in Figure 1, the valve is pushed up to open the valve 6 and supply water to the nozzle pipe 3. When in use, the case 2 and the existing faucet main body 1 are connected with a nut 8 as shown in the figure, but in the case of this invention, the male thread 2a at the upper end of the case 2 is screwed into the male thread 2a. The female threads 8a at the lower end of the nut 8 are each formed into a left-hand thread, whereas the female threads 8b at the upper end of the nut 8 are formed into a right-hand thread to match the male threads 1b at the lower end of the faucet body 1. This is the most important feature of the one-touch faucet of this invention.

(Effect of the invention) Since the present invention has the above configuration, when connecting the faucet main body and the case, by rotating the nut that connects them clockwise, the male part of the lower end of the faucet main body can be connected. The point where the nut spirals upward along the screw is
This is the same as in the conventional case, but in the case of the present invention, the female thread at the lower end of the nut and the male thread at the upper end of the case are left-handed threads, so they are relatively reversed in conjunction with the screwing movement of the right-hand thread. The faucet main body and case can be fastened and fixed in one rotation by screwing in the direction that attracts the case and tightening the upper and lower right-hand screws and left-hand screws at the same time. The inconvenience of tightening one screw causing the other screw to loosen is completely eliminated, and even an amateur can install a one-touch faucet extremely easily, quickly and reliably. Coupled with the fact that the device has a simple structure and can be provided at low cost, this device exhibits remarkable practical effects.
