Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention belongs to the field of water distribution equipment, and is used for a device that remotely opens and closes a faucet installed outdoors from indoors.

(Prior art) There are various types of remote control switches, from electrical to mechanical types, but among the mechanical types, switches with rotating handles are particularly difficult to improve in terms of function and cost. It was insufficient.

(Problem that the invention attempts to solve) This invention pursues the relationship between function and cost, and attempts to provide an inexpensive remote-controlled switch that can be expected to be economically effective without impairing the faucet's opening/closing function. It is something.

(Means for Solving the Problems) The above object of the present invention is to provide a member used for a transmission mechanism by handle operation by disposing a joint having a cylindrical portion having an hourglass-shaped cross section and having long grooves extending therethrough, disposed above and below, The spindle of the faucet is locked to the lower joint, the handle operation system is connected to the upper joint, and the joints are connected by rods that are engaged with pins in their respective long grooves to transmit rotation and expand and contract. achieved.

(Function) By engaging the pin in the long groove that allows the inclination angle of the connecting rod, the pin transmits the rotation from the joint to the rod while sliding up and down the long groove, and also Since the outer periphery of the rod is in contact with the inner periphery of the joint, there is no unnecessary movement and the function is equivalent to that of a hook-type universal joint.

(Example) Hereinafter, the present invention will be explained in detail with reference to an example. As shown in Figs. The bevel gear 4 of the handle operating part a is locked to the shaft part 3, and the lower joint 5 also has a cylindrical part with an hourglass-shaped cross section and similar long grooves 2 on the left and right sides. are provided opposite to each other, and a spindle 7 of a water faucet (not shown) is locked to the shaft portion 6. A pin 9 fixed to the cylindrical rod part 8 is engaged with the long groove 2 of the upper joint 1, a pin 9 fixed to the round bar rod part 10 is engaged with the long groove 2 of the lower joint 5, and the cylindrical rod part 8 and the vertical middle part of the round rod part 10 is the square shaft 1
1 and the square pipe 12, rotational force can be transmitted in a telescopic manner.

(Effects of the invention) As described above, according to the invention, the structure of the joint is simple, so the cost is low, the transmission force is transmitted without any play, and the joint has the same function as a commonly used hook-type universal joint.

[Brief explanation of drawings]

FIG. 1 is a longitudinal cross-sectional view of the handle operating portion a of the present invention, and FIG. 2 is an explanatory cross-sectional view showing a state in which the lower joint is locked to the spindle of a water faucet. In the figure, 1 is an upper joint, 2 is a long groove, 5 is a lower joint, 8 is a cylindrical rod part, 9 is a pin, 10 is a round bar rod part, and a is a handle operating part.

Claims (1)

[Scope of utility model registration request] Joints each having long grooves facing each other in a cylindrical part having a drum-shaped cross section are disposed above and below, the spindle of a water faucet is engaged with the lower joint, and a handle operation system is engaged with the upper joint. A remote open/close switch for a faucet, which is connected telescopically to transmit rotation with a pin-engaged rod in each long groove.
