State the top of resetting spring and the bottom of footstock to offset, the first hinge bar, the second hinge bar are equipped between the base and footstock
With the 3rd hinge bar, the base, the first hinge bar, the second hinge bar, the 3rd hinge bar and footstock are hinged successively, the switch
Groove both sides are through there is threaded mandrel, and the threaded mandrel end is equipped with top plate, and the top plate offsets with the second hinge bar.
Preferably, the switch groove both sides are equipped with and the matched threaded hole of threaded mandrel, the position of the threaded hole
It is corresponding with the point midway of the second hinge bar.
Preferably, the base and the first hinge bar, the first hinge bar and the second hinge bar, the second hinge bar and the 3rd
All it is hinged between hinge bar, the 3rd hinge bar and footstock equipped with shaft.
Preferably, first hinge bar, the second hinge bar and the 3rd hinge bar are equipped with two groups, respectively positioned at reset bullet
The both sides of spring.
Preferably, the footstock is a T-shaped square that can block runner in valve body.
The utility model has the technical effect that following aspect：Set by the cooperation of base, resetting spring and footstock
Count to block runner, with reference to the cooperation of threaded mandrel and the first hinge bar, the second hinge bar and the 3rd hinge bar, by artificial
Rotate threaded mandrel so that footstock, which rises, blocks runner, so that original hydraulic control system is instead of, after avoiding the occurrence of failure
The situation that quick closing valve valve can not be opened.
Brief description of the drawings
Fig. 1 is a kind of structure chart of the device of manual control hydraulic quick closing valve valve switch of the utility model.
Embodiment
In the present embodiment, it is to be understood that term " centre ", " on ", " under ", " bottom ", " right side ", " left end ",
" top ", " back side ", " middle part ", etc. instruction orientation or position relationship be based on orientation shown in the drawings or position relationship, only
Be for the ease of describing the utility model, rather than instruction or imply signified device or element must have specific orientation,
With specific azimuth configuration and operation, therefore it is not intended that limitation to the utility model.
In addition, the connection between component or fixed form if not otherwise specified in this embodiment, it is connected or solid
It can be to be fixed by bolt commonly used in the prior art or pin is fixed to determine mode, or the mode such as axis pin connection, therefore, at this
No longer it is described in detail in embodiment.
Embodiment 1
As shown in fig.1, a kind of device of manual control hydraulic quick closing valve valve switch, the switch being installed on inside valve body 1
In groove 2, include base 3, resetting spring 4 and footstock 5, the base 3 is fixed on the bottom of switch groove 2, the resetting spring 4
Bottom is fixed on base 3, and the top and the bottom of footstock 5 of the resetting spring 4 offset, and the footstock 5 can blocking valve for one
The T-shaped square of runner in body 1, it is hinged to be equipped with the first hinge bar 6, the second hinge bar 7 and the 3rd between the base 3 and footstock 5
Bar 8, the base 3, the first hinge bar 6, the second hinge bar 7, the 3rd hinge bar 8 and footstock 5 are hinged successively, the base 3 with
First hinge bar 6, the first hinge bar 6 and the second hinge bar 7, the second hinge bar 7 and the 3rd hinge bar 8, the 3rd hinge bar 8 and top
All it is equipped with shaft 9 between seat 5 to be hinged, first hinge bar 6, the second hinge bar 7 and the 3rd hinge bar 8 are equipped with two groups, difference
