Abstract
The utility model provides a stepless regulating lever switch key which comprises a regulating lever, a handle, a key lever and a key head, wherein the regulating lever is formed by welding a transverse cylindrical short pipe and a vertical polygonal long pipe into a whole, and the longitudinal section of the regulating lever is in an T shape; the handle is a transverse cylindrical long pipe, and the diameter of the handle is slightly smaller than that of the transverse cylindrical hollow short pipe; the key lever is a vertical polygonal long pipe, and the lower end of the key lever is connected with the key head. The regulating lever is inserted into the longitudinal hollow inner part of the key lever and can stretch out and draw back for stepless regulation in an effective travel range. The handle is inserted into the transverse hollow inner part of the regulating lever to form the T shape, so that the key head can rotate under the action of external force to realize the turning-on and turning-off actions of a valve.
Description
Technical field
The present invention relates to gas valve field, more specifically, relate to the step-less adjustment lever switch key of buried polythene for a kind of combustion gas (PE) gas valve.
Background technique
Buried polythene for traditional combustion gas (PE) valve, the length of switch key bar is uncontrollable, for the type that diffuses of different structure buried polythene (PE) valve for combustion gas, must be equipped with the switch key of different key bar length, the using scope of valve switch key is subject to narrow limitation.
Summary of the invention
The utility model provides the step-less adjustment lever switch key of buried polythene for a kind of combustion gas (PE) valve, the length that is characterized in key bar can realize step-less adjustment, use comfort and convenient, to adapt to the demand of the type that diffuses buried polythene (PE) valve for combustion gas of different structure, expand the using scope of switch key.
In order to realize foregoing invention object, the invention provides a kind of step-less adjustment lever switch key, comprise adjustable lever, handle, key bar, 4 parts of key bit, it is characterized in that,
Adjustable lever is that a horizontal cylinder short tube and a vertical polygonal long tube are welded into entirety, and its longitudinal section is T word shape,
Handle is a horizontal cylinder long tube, and diameter is slightly less than the diameter of the horizontal cylinder hollow short tube of adjustable lever,
Key bar is a vertical polygonal long tube, and lower end and key bit are welded into entirety, described adjustable lever and key bar fit.
Described polygonal is triangle or square.
Described adjustable lever, handle and key bar is hollow stem.
Described handle two ends endoporus sealing.
Described key bit is that a vertical square short tube and a square metal plate are welded into entirety, and its longitudinal section is reverse U shape shape.
Further, provide a kind of combustion gas buried polyethylene valve, comprise according to above-mentioned step-less adjustment lever switch key.
The utility model advantage is,
1. the switch key that provides a kind of length to regulate, can realize the switch of the combustion gas that is embedded in the end, ground, and does not need to be equipped with the key bar of specific length.
2. can arbitrarily regulate the length of key bar, competent different occasion, and do not need the process of complicated adjusting length while using.
