Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As shown in Figure 1, a kind of self-locking treadle valve provided by the utility model, including valve body 1, connecting plate 2, latch components
22, pedal 3 and hook 6, are equipped with connecting plate 2 on valve body 1, and the upper surface of connecting plate 2 is equipped with bracket 21 and latch components 22,
Described 3 one end of pedal is installed on the stent 21 by shaft A41, and is also equipped with torque between pedal 3 and bracket 21
Spring A51, the hook 6 are mounted on the other end of pedal 3 by shaft B42；The hook opening direction branch of the hook 6
The opposite direction of frame 21；The latch components 22 include the lock buckling groove 221 of opening upwards, have extension in the one side wall of lock buckling groove 221
Hook axial trough 222, hook axial trough 222 are located at one end on lock buckling groove 221 far from bracket 21, setting in the hook axial trough 222
There are lateral sliding rail 223 and vertical baffle 226, hook axis 224 is installed on sliding rail 223, links up with axis 224 far from lock buckling groove
The one of 221 is terminated with wirerope B72, and wirerope B72 is connect with extension spring A225, the extension spring A225 installation site
Direction positioned at lock buckling groove 221 far from bracket 21；221 bottom of lock buckling groove is provided with backing plate 227, and backing plate 227 and baffle 226 are one
Body structure, and the lower section of backing plate 227 and baffle 226 is equipped with extension spring B228；The hook axis 224 is far from lock
One end of slot 221 is connected with wirerope A71, and the other end of wirerope A71 is connected on pedal 3；The hook 6 can be with stepping on
Plate 3 surrounds the rotation of shaft A41 and protrudes into lock buckling groove 221.Further, the centre of the wirerope A71 is also connected with
Extension spring C73.Further, the link position of the wirerope A71 and pedal 3 be located at shaft A41 and shaft B42 it
Between.Further, in the latch components 22, be also equipped with castor 229 close to one end of bracket 21, castor 229 with
Axis 224 is linked up in same level, wirerope A71 passes through castor 229 and connect with hook axis 224.Further, described
It is also equipped with torsion spring B52 between pedal 3 and hook 6, and pedal 3 is provided with hook limit plate 31.
The working principle of the utility model are as follows: when just opening when state, pedal 3 is at torsion spring A, so that connection hook
63 one end of pedal tilts, and wirerope A71 is stretched, and links up with axis 224 at this time and pulls on sliding rail 222 under wirerope A71 effect
One end of most advanced bracket 21, extension spring A225 at this time are equally stretched under the drive of wirerope A71；Then underfooting
Pedal 3 when hook 6 enters in lock buckling groove 221, and hook 6 catches on hook axis 224, and is realized self-locking function, is then needed out
When lock, it is only necessary to continue pedal 3 down, hook 6 withstands backing plate 227 and moves down, and backing plate 227 also drives baffle 226 down
Movement, when baffle 226 exits hook axial trough 222 completely, wirerope A71 belongs to the state of being totally released at this time, and hook axis 224 exists
The movement in hook axial trough 222 under the pulling of extension spring A225 is unclamped at this point, hook 6 cannot catch on hook axis 224 in foot
After pedal 3, pedal 3 returns to initial position, and during this, baffle 226 returns to initial position, and tensional state is presented in wirerope A71,
The top design of baffle 226 is triangular structure of right angle simultaneously, and in its bevel edge direction hook axial trough 222；Hook axis 224 exists
Under the drive of wirerope A71, the pulling force of wirerope A71 overcomes extension spring A225 pulling force and extension spring B228 elastic force, so that
Hook axis 224 returns to initial position.Simultaneously in order to avoid the moving position of pedal 3 is excessive, wirerope A71 is broken, so
The centre of wirerope A71 is provided with extension spring C7.
