Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by the technical personnel in the field without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the directions or positional relationships indicated as the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., appear based on the directions or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" should be interpreted broadly, e.g., as being either fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case to those skilled in the art.

Referring to the accompanying drawings 1-6, a gas valve with valve lock, including main part 1, be provided with switch 4 in the main part 1, switch 4's top is provided with switch roof 5, the bottom surface welding of switch roof 5 has welded pipe 6, telescopic link 10 is equipped with in the interpolation of welded pipe 6, the top section welding of telescopic link 10 has spring 9, spring 9 welds in the lumen of welded pipe 6, and notch 7 has been seted up to welded pipe 6 top section, the top section of telescopic link 10 slides through welded limiting plate 14 and moves towards in notch 7, the top section of notch 7 is installed through the screw and is used for the spacing fixed plate 8 of spring 9, telescopic link 10 receives spring 9 to influence can stretch out by elasticity downwards, can make telescopic link 10 upwards return in welded pipe 6 when upwards pulling limiting plate 14.

As shown in fig. 1, be provided with external screw thread 2 on the top segment outer wall of main part 1, main part 1 installs adjusting ring 3 through external screw thread 2, adjusting ring 3's outer wall is provided with round ear seat 11, spacing hole 13 has been seted up on ear seat 11, adjusting ring 3 rebound back, can be close to the top segment of switch 4 handle, because the width between the adjacent two ear seats 11 is greater than the diameter size of switch 4 handle, consequently, can be spacing the handle between adjacent two ear seats 11, make the switch 4 of closing the gas can not send the rotation because of children touch from this.

In order to further prevent the switch 4 from being opened by a child, the telescopic rod 10 is arranged right above the limiting hole 13, the telescopic rod 10 which extends downwards under the action of the spring 9 extends into the limiting hole 13 to further lock the position of the adjusting ring 3, and therefore the switch 4 between the two lug seats 11 of the adjusting ring 3 is further prevented from rotating after being limited.

The ear seat 11 still installs gag lever post 12 by outer terminal surface through the thread bush, and the outer end of gag lever post 12 is provided with the knob, and the artificial outside rotatory knob can outwards screw out gag lever post 12, utilizes the gag lever post 12 of screwing out can prolong the length of ear seat 11 to can be better utilize two adjacent ear seats 11 to the inboard by spacing switch 4 handle portion prevent changeing spacingly.

After the valve body 1 of the structure is used, in order to prevent a child from operating the switch 4 by mistake to open the valve, the adjusting ring 3 can move upwards under the action of the large-pitch external threads 2 to enable the adjusting ring to reach the position close to the top section of the handle of the switch 4, the two adjacent lug seats 11 on the adjusting ring 3 are positioned at two sides of the handle, the limiting rod 12 is screwed out by manually rotating the knob outwards, the length of the lug seats 11 can be prolonged by utilizing the screwed limiting rod 12, so that the adjacent lug seats 11 can be better utilized to prevent the handle part of the switch 4 with the inner side limited from rotating and limiting, meanwhile, the telescopic rod 10 is forced to extend downwards into the limiting hole 13 under the action of downward elastic pressure of the spring 9 to lock the position of the adjusting ring 3, the switch 4 positioned between the two lug seats 11 of the adjusting ring 3 can be further prevented from rotating after being limited, when the child holds the switch 4, the switch 4 cannot be rotated to open the valve, under the cooperation of the double anti-rotation structure, the valve can be installed on a gas pipeline for use, and the safety factor is improved.
