Detailed Description

The following is a specific embodiment of the present invention, and the technical solution of the present invention is further described with reference to fig. 1-3, but the present invention is not limited to this embodiment.

As shown in fig. 1-2, the present invention provides a plug valve locking member 30 for a plug valve, and a plug valve using the plug valve locking member 30. The plug valve comprises a support 10, a clamp spring 20, a plug valve locking member 30, a spring 40, a knob rod 50, a microswitch 60 and a bottom plate 70.

As shown in fig. 1, the plug valve locking member 30 is in a bottle cap shape, the top of the plug valve locking member 30 is provided with a first through hole 31, the side of the plug valve locking member 30 is provided with a first notch 32 and a second notch 34, the first notch 32 and the second notch 34 are arranged at the outer side of the first through hole 31, the plug valve locking member 30 is further provided with a first protrusion 33, and the first protrusion 33 is arranged in the second notch 34. So set up and to realize locking structure after making plug valve locking piece 30 both can cooperate through first breach 32 and support 10, can realize the effect of cam through first arch 33 again, can carry out rotary ignition and make the plug valve of using this locking piece reduce a part simultaneously, practice thrift the cost.

Further, the first protrusion 33 divides the second notch 34 into two parts. The arrangement is such that both sides of the first protrusion 33 are notched to save material.

Further, the first notch 32 and the second notch 34 extend along the sides of the stopcock locking member 30 and all the way to the top of the stopcock locking member 30. The arrangement is such that the radial depth of the first and second notches 32, 34 is sufficiently large.

Further, the first notch 32 is larger on the side of the plug valve locking member 30 closer to the top than on the side away from the top. This arrangement allows the first notch 32 to better cooperate with the bracket 10 to form a locking structure.

Further, the first through hole is a D-shaped hole. The arrangement allows the knob lever 50 to pass through, and also provides a limiting function, which facilitates the knob lever 50 to drive the plug valve locking member 30.

As shown in fig. 2 to 3, the bracket 10 has a second protrusion 11, the second protrusion 11 is in snap-fit connection with the first notch 32, the middle of the bracket 10 has a second through hole 12, the bracket 10 further has two mounting edges 13, the mounting edges 13 have bracket mounting holes 14, the bracket mounting holes 14 are preferably 4, and the bracket 10 is in bolt connection with the bottom plate 70 through the bracket mounting holes 14. Through setting up support installation limit 13 for connect more firmly.

The bottom plate 70 is provided with a third through hole 71, the third through hole 71 is arranged in the middle of the bottom plate 70, and the bottom plate 70 is detachably connected with the bracket 10. The bottom plate 70 further has a bent edge, and the first notch 32 and the second protrusion 11 are disposed on the same side of the bent edge. The arrangement makes the plug valve more reasonable in structure.

The knob rod 50 is sequentially inserted into the second through hole 12, the first through hole 31 and the third through hole 71. The stopcock locking member 30 is slidable axially along the knob stem 50 and rotatable upon rotation of the knob stem 50. Preferably, the knob stem 50 is D-shaped in cross section so as to be conveniently fitted into the first through hole 31.

The micro switch 60 is disposed on the bottom plate 70, and the micro switch 60 is detachably connected to the bottom plate 70. Preferably, the microswitch 60 is bolted to the base plate 70. The bolt connection is used, so that the installation of the microswitch 60 is more stable.

The microswitch 60 abuts against the first projection 33. When the knob lever 50 is rotated, it will rotate the plug valve locking member 30 and the rotation of the first protrusion 33 will trigger the micro switch 60 to send out an ignition signal. Because plug valve locking piece 30 self just can carry out the rotary ignition, no longer need install the cam on the knob pole, the part of installation has lacked one on the knob pole for the support height can reduce 1.5~3mm, because the high reduction of support, uses the utility model discloses the whole height of cooking utensils of plug valve can reduce.

The plug valve further comprises a clamp spring 20, the clamp spring 20 is arranged between the plug valve locking piece 30 and the support 10, and the clamp spring 20 is fixedly connected with the knob rod 50. The clamp spring 20 is fixed on the knob rod 50, when the knob rod 50 is pressed down, the clamp spring 20 is pressed down together with the knob rod 50, so that the plug valve locking member 30 slides downwards along the axis, and the first notch 32 is separated from the second protrusion 11, so that the plug valve is unlocked.

The plug valve further comprises a spring 40, the spring 40 is sleeved on the knob rod 50, and two ends of the spring 40 are respectively abutted against the bottom plate 70 and the locking sheet 30. The spring 40 is used to reset the plug valve locking member 30, and when a firing event is completed, the plug valve locking member 30 returns to its initial position under the action of the spring 40.

The operation steps of the plug valve are as follows:

1. pressing down the knob rod 50, the plug valve locking member 30 slides downwards under the action of the clamp spring 20, the first notch 35 is separated from the bulge 11, the plug valve is in contact locking, and the spring 40 is compressed;

2. rotating the knob lever 50 counterclockwise to rotate the first protrusion 33 counterclockwise, triggering the micro switch 60 to send an ignition signal;

3. clockwise rotation knob pole 50 to initial position, release knob pole 50 simultaneously, plug valve locking member 30 resets under the effect of spring 40, first breach 35 with protruding 11 snap-fit connection.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
