In the invention, the bottom of the plunger is in threaded connection with the connecting plate, and a certain distance is reserved between the connecting plate and the locking sleeve. The connecting plate is fixedly connected with the first to-be-locked member, and can be fixedly connected through bonding or other modes.
The invention takes the manual control of the tripod oil bag as an example for further explanation: when the user presses the oil bag machine (i.e. the driving member 42 above) to pressurize the oil bag (i.e. the bag body 41 above), the liquid in the oil bag is fed into each oil bag (i.e. the pressing bag 371 above) through the telescopic corrugated pipe (i.e. the sleeve 43 above) and the oil bag feeding pipe (i.e. the pipe 372 above). Since the last oil bag outlet pipe is closed, the oil bag extends to push the plunger to move downwards, compressing the return spring (i.e. the elastic element 39). Meanwhile, the locking plate 35 connected by the pin 36 is retracted into the through hole 333 of the locking sleeve 33, and at this time, the oil pressure is maintained, and the product can be freely retracted.
When the first member 21 is retracted to a predetermined position, the trigger is released and the plunger moves upward by the return spring (see fig. 3). And the locking plate 35 extends out of the through hole 333 on the locking sleeve 33 to form a certain angle with the inner wall of the second member 22 to be locked. When the second member to be locked 22 and the first member to be locked 21 are stressed and contracted (such as putting a weight, etc.), the reaction force of the first member to be locked 21 connecting the plunger through the connecting plate 31 converts the contracted force into an outward expansion force through the locking plate 35, the second member to be locked 22 and the first member to be locked 21 are locked and fixed, the locking force is larger, and the outward expansion force is larger as the contracted force is larger, so that the product is locked reliably. When a certain telescopic leg needs to be adjusted, the corresponding locking device can be unlocked by pressing the corresponding oil bag by buckling the oil bag trigger, so that the accurate control of the specific telescopic leg can be realized.
When the hydraulic system is damaged and cannot be used, the first to-be-locked member 21 can be directly rotated to pull out the plunger for unlocking. Because the pin shaft on the plunger is clamped in the accommodating cavity 331 of the locking sleeve 33, the limiting groove 332 on the outer surface of the locking sleeve 33 is aligned with the anti-rotation protruding block of the second to-be-locked member 22 and can not rotate, so that when the first to-be-locked member 21 is forcefully rotated to break the limiting of the notch groove 311 of the connecting plate 31, the plunger pulls out the compression return spring downwards, and the locking plate is retracted into the locking sleeve. The first member to be locked 21 and the second member to be locked 22 are unlocked and can be freely retracted. When the first member 21 to be locked is rotated anticlockwise after the first member is retracted to a preset position, the plunger is retracted under the action of the return spring, the locking plate extends out of the locking sleeve, and the first member 21 to be locked and the second member 22 to be locked are locked.
