The working principle of the invention is as follows:
in the assembling process, the oil inlet pushing block 5 is propped up by the adjusting oil cylinder 6, at the moment, the oil conveying channel 4 is blocked by the end part of the oil inlet pushing block 5, meanwhile, the ejector rod 7 is clamped on the oil inlet pushing block 5 by the elasticity of the pushing spring 8, the movement of the oil inlet pushing block 5 is limited, then, the connecting frame 1 moves to the upper part of the positioning groove 21, and when the connecting frame 1 is pressed down, the connecting frame 1 is attached to the positioning groove 21, meanwhile, the locking wheel 16 and the positioning wheel 18 rotate respectively through the corresponding mounting rod 20, and in the continuous downward movement process of the connecting frame 1, the detecting head 12 is continuously pressed, the upward pressing of the detecting head 12 can enable the detecting head 12 to block the connecting channel 13, the medium in the pressing cavity 10 is further pressed upwards through the blocking 9, the compression of the pushing spring 8 is realized through the blocking 9, at the same time, the strength of the pushing rod 7 is further increased, then, the continuous downward moving connecting frame 1 enables the connecting channel 13 to be communicated with the liquid draining channel 11, and then, the medium in the pressing cavity 10 is enabled to flow out of the connecting channel 13 from the pressing cavity 10 to the locking wheel 15, and the locking wheel 18 is further pushed out of the locking rod 15;
At this time, because the extrusion chamber 10 is further increased in pressure due to the elastic extrusion of the pushing spring 8, the adjusting pull rod 14 is attached to the locking rod 15 in the pushing process of the locking rod 15, the locking rod 15 is prevented from excessively extending through the adjusting pull rod 14, on the other hand, the push rod 7 still keeps being locked on the oil inlet push block 5, so that the movement of the oil inlet push block 5 is limited, the adjusting oil cylinder 6 does not need to keep the continuous high pressure in the working process, in particular implementation, in order to ensure that the pressure is always present in the oil buffer chamber 17, and simultaneously, the oil pressure is prevented from reversely pushing the oil inlet push block 5 to move rightwards, a one-way check valve (also in order to prevent the oil cylinder from leaking) can be added in the oil cylinder 6, so that the medium oil in the oil buffer chamber 17 can not simultaneously push the oil inlet push block 5 to rightwards, and further the pressure is always present in the oil buffer chamber 17 to push the locking rod 15, and the oil buffer chamber 15 is prevented from backing.
When the oil tank is required to be disassembled, the oil inlet pushing block 5 is forced to be pulled out by applying pressure to the adjusting oil cylinder 6, the ejector rod 7 is pushed to further compress the pushing spring 8, when the oil inlet pushing block 5 is pulled, media in the oil buffer cavity 17 can flow back to the oil storage tank 3 due to being pressed, the locking rod 15 can be used for releasing the limitation of the locking wheel 16 and the positioning wheel 18 when the oil inlet pushing block 5 is continuously pulled, so that the connecting frame 1 can be rapidly pulled out from the bucket 19, and the locking wheel 16 and the positioning wheel 18 rotate relatively when the connecting frame 1 is pulled out, so that the detachment of the bucket 19 is not influenced, and when the connecting frame 1 is completely detached, the self-gravity and the inclined part of the ejector rod 7 are pushed down by the oil inlet pushing block 5, the detection head 12 is pushed out to ensure the next use, and the connecting frame 1 and the bucket 19 can be rapidly assembled again according to the above.
