Description

[Detailed Description of the Invention] The present invention relates to an improvement in the knob mounting structure of a gas appliance.

Conventionally, the rotor 31 and the knob 3, which rotate together with the closure 2, are constructed by screwing the tip of a screw 5 inserted through the through hole 26 of the knob 30 into the screw hole 16 of the rotor 31, as shown in FIG. I just installed it.

For this reason, the rotational force when rotating the closure 2 with the knob 3 is concentrated on the attachment part made by the screw 5, which may damage the knob 3 or wear out the attachment part between the knob 3 and the rotor 31. There was a drawback that sagging, etc. occurred.

The present invention was made in view of the drawbacks of the conventional example,
The purpose of the present invention is to transfer the rotational force of the knob to the rotor by locking a locking protrusion that projects on the rotor that works with the closure and a locking seat that is recessed in the knob. To provide a knob mounting structure for a gas appliance that accurately transmits power to a closing member via the rotor and prevents the knob from being damaged by applying an overcurrent load to the mounting part between the rotor and the knob.

The present invention will be explained in detail below.

The knob mounting structure of the gas appliance according to the present invention is that a closure 2 for opening and closing the gas passage I in the appliance tap body 15 is rotatably installed inside the appliance tap body 15 of the gas cock body 1, and rotates integrally with the closure 2. A screw hole 16 is provided approximately in the center of the end surface opposite to the closing member 2 of the movable rotor 31, and a locking protrusion 6 is provided beside the screw hole 16 on this end surface, and a knob disposed on the rotor 31. Insert the screw 5 from the surface side of the knob 30 into the through hole 26 provided through the center of the rotor 31, and insert the tip of the screw 5 into the screw hole 16 of the rotor 31.
The knob 3 is attached to the rotor 31 by screwing into the rotor 31, and the locking projection 6 of the rotor 31 is locked to the locking seat 10 recessed on the back surface of the knob 3, By configuring as described above, the drawbacks of the conventional example are solved.

Next, the present invention will be described in detail according to an example in which the present invention is used in a gas outlet.

A flange pipe 13 that can be connected to a gas pipe and a gas cock main body 1 for embedding are embedded in a recess 14 provided in the wall surface 9 and opening into the room.
The flange pipe 13 is connected to 5.

A gas opening/closing closure 2 is rotatably installed in the center of the appliance tap body 15, and by rotating the closure 2, the gas passage 7 of the appliance tap body 15 can be opened and closed. ing.

Upper side of closure 2 (in Figure 1, the right side is the bottom and the left side is the top)
An annular interlocking element 11 is fitted on the interlocking element 11 so as to be vertically movable.
and the closure 2 rotate together.

A cap-shaped rotor 31 is fitted onto the upper part of the closure 2, and a spring 32 is interposed between the rotor 31 and the closure 2, and a spring 32 is interposed between the rotor 31 and the interlock 11. A spring 34 is interposed, and when the interlocking element 11 moves upward against the spring 34, the pin 12 of the interlocking element 11 and the notch groove (not shown) at the lower end of the rotor 31 engage and rotate. The child 31 and the closure 2 can rotate together.

Further, the upper part of the rotor 31 is engaged with the lid part 29a of the casing 29 of the gas cock body 1 to prevent it from coming off upward.

Further, a mounting protrusion 33 having a screw hole 16 screwed therein is provided at the center of the upper part of the rotor 31, and locking protrusions 6 are protruded from both sides of this mounting protrusion 33.

The planar shape of this locking projection 6 is a locking dowel 8 shown in FIG.
The outer half portions 18 of the two opposing side surfaces 11 having the same shape as , are tapered.

As shown in FIGS. 7 to 10, the knob 3 has a circular thin-walled flange 25 formed from the lower surface of the knob body 24, and a through hole 26 is bored in the center of the knob body 24. , the lower end side is recessed in a step-like manner.

The recessed stepped portion 21 has a substantially rectangular cross section similar to the stepped hole 20 of the spacer 40, and its short side 27a swells outward in an arc shape.

A locking place 10 is recessed on both sides of this recessed stepped portion 210.

After inserting the locking projection 6 of the rotor 31 into the locking hole 10 of the knob 3, the tip of the screw 5 inserted through the through hole 26 is screwed into the screw hole 16 of the mounting projection 33. knob 3
is screwed to the rotor 31.

In this way, the screw 5 acts only to screw the knob 3 onto the rotor 31, and the rotational force of the knob 3 is transmitted between the locking protrusion 6 and the locking seat 10, and between the knob 3 and the rotor 31. The rotational force of the knob 30 is accurately transmitted to the closure 2 via the rotor 31, and the rotational force of the overcurrent is not applied to the screwed attachment part of the knob 3 and the rotor 31. First, damage to the knob 3 can be prevented.

Note that FIGS. 3 to 6 show a spacer 4 that forms the back side of the knob 3 by attaching it as necessary. 20 and a disk 190 on one side 21
Locking holes 10 are recessed on both sides of the stepped hole 20, and the disc 1
On the other side 220 of 9, locking dowels 8 are recessed on both sides of the stepped hole 20.

However, by providing one or more spacers 4 as described above on the back surface of the knob 3, the surface of the knob 30 and the wall surface 9 can be made almost equal.If the gas outlet is located shallowly from the wall surface 9, the number of spacers 4 can be reduced. On the other hand, if the depth is deep, the number of spacers 4 may be increased.

In this case, the rotor 31 and the spacer 4 between the knob 3 and the knob 3
Since the spacers 4 and the spacer 4 and the surface of the knob 30 engage with each other, the rotation of the knob 30 is accurately transmitted to the closure 2, and slippage occurs between the closure 2, the spacer 4, and the surface of the knob 3. The closure 2 can be opened and closed reliably without any problems.
Therefore, there is an advantage that the surface of the knob 30 can be easily aligned with the wall surface 9 by increasing or decreasing the number of spacers 4 on site, and the installation work can be performed accurately and quickly.

Reference numeral 28 denotes a lid, which is pivotally supported on the casing 29 of the gas cock main body 1, so that its front opening can be closed.

Further, 30 is a plug to which a socket (not shown) is detachably connected.

When the socket is connected to the plug 30, the pin 12 of the interlocking element 11 is pushed up via the scene-like interlocking member 35, and the pin 12 engages with the notched groove of the rotor 31, causing the rotor 31 and the closing element 2 to interlock. It rotates integrally via a child 11, and by rotating the knob 3, the closing member 2 is opened and closed.

Further, when the knob 3 is rotated to close the closing member 2 and the pin 12 is pushed down together with the interlocking element 11 via the rotor 31 by operating the knob 3, the socket is removed from the plug 30 via the interlocking member 35. Will be removed.

As described above, the present invention involves inserting a screw from the surface side of the knob into a through hole in the center of the knob, which is disposed on a rotor that rotates integrally with the closure, and then inserting the tip of the screw into the rotor. The knob is attached to the rotor by screwing into the screw hole approximately in the center of the rotor.
Of course, the knob is attached to the rotor with screws, but a locking protrusion is provided next to the screw hole of the rotor, and the locking protrusion is engaged with a locking hole recessed on the back of the knob. Because of this, the rotational force when turning the knob is transmitted through the locking position and the locking protrusion, and no force is applied to the screw-mounted mounting part, which can damage the knob or cause it to spin idly. The advantage is that there is no risk of this happening.
