Abstract
The utility model relates to hydraulic sealing pliers, which is mainly composed of a pliers body and a hydraulic oil cylinder, wherein, the hydraulic oil cylinder is installed at the inner part of the pliers body, the output end of the hydraulic oil cylinder is connected with one end of a hydraulic pushing rod, the other end of the hydraulic pushing rod is mutually pushed against and connected with the reverse side of a lower tightly-pressed block, one end of the upper tightly-pressed block is axially connected with the pliers body through a fixed pin, the other end of the upper tightly-pressed block is movably connected with the pliers body, and a tightly pressed working cavity is formed between the upper tightly-pressed block and the lower tightly-pressed block. The hydraulic sealing pliers has the advantages that because the upper tightly-pressed block and the lower tightly-pressed block structures are adopted, the volume is greatly reduced, the carrying and the operation of the hydraulic sealing pliers are convenient, the cost is low, and the hydraulic sealing pliers is suitable for different construction environments, the pressure can be adjusted, and the compaction degree is high and stable.
Description
Technical field
The utility model relates to field of tool, mainly is a kind of hydraulic packing pincers.
Background technology
At present, the pressing type pipe joint has been widely used in the pipe arrangement equipment of Architectural Equipment etc., after inserting thin-wall pipe in the joint, periphery by the forcing press butt joint is pressurizeed, dwindle from diameter, thereby joint pipe fitting and joint are with sealing pressure fluid as near the connecting portion joint end to the central authorities of pipe fitting insertion portion.Mould by forcing press pressurizes, its use cost height, and volume carries inconvenience greatly, and use occasion has bigger limitation.
The utility model content
The utility model will solve above-mentioned existing shortcoming, provides a kind of volume hydraulic packing pincers little and easy to use.
The technical scheme that the utility model addresses the above problem employing is: this hydraulic packing pincers, mainly comprise caliper and hydraulic jack, hydraulic jack is installed in caliper inside, the output of described hydraulic jack is connected with an end of hydraulic mandril, the other end of hydraulic mandril connects with the reverse side of following compact heap, one end of last compact heap is coupling by fixed pin shaft and caliper, and the other end of last compact heap and caliper flexibly connect, and forms between last compact heap and the following compact heap and compresses working chamber.
The effect that the utility model is useful is: owing to adopted the structure of last compact heap and following compact heap, thereby volume reduces greatly, portably uses conveniently, and cost is low and adapt to various different construction environments, adjustable in pressure, and the compactness height is stablized.

Description of reference numerals: caliper 1, last compact heap 2, following compact heap 3, hydraulic mandril 4, hydraulic jack 5, hydraulic selector 6, connection cord 7, fixed pin shaft 8, active pin shaft 9, cannelure 10, hydraulic handle 11, the first latches 12, the second latches 13.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in the figure, this hydraulic packing pincers mainly comprise caliper 1 and hydraulic jack 5, and hydraulic jack 5 is installed in caliper 1 inside, and caliper 1 is provided with hydraulic handle 11 and hydraulic selector 6.The output of described hydraulic jack 5 is connected with an end of hydraulic mandril 4, the other end of hydraulic mandril 4 connects with the reverse side of following compact heap 3, one end of last compact heap 2 is by fixed pin shaft 8 and caliper 1 be coupling (fixedlying connected), the other end of last compact heap 2 and caliper 1 flexibly connect, and form the corresponding working chamber that compresses of cross sectional shape with the pressing type pipe joint between last compact heap 2 and the following compact heap 3.
Described fixed pin shaft 8 is installed in an end of compact heap 2 and caliper 1 junction and is fixed together by second latch 13, and the other end of last compact heap 2 and caliper 1 junction are provided with active pin shaft 9 and link together by first latch 12.Be provided with between first latch 12 and second latch 13 and be used for safe connection cord 7.
The cross section of described caliper 1, last compact heap 2 and following compact heap 3 is the U-shaped of opening, the described mating surface of going up compact heap 2 and following compact heap 3 is provided with cannelure 10, the circular section shape of the shape of this cannelure 10 and pressing type pipe joint is corresponding, be provided with two road cannelures 10 in the present embodiment, then corresponding to the pressing type pipe joint that two road hold-down rings are arranged; If the cross sectional shape of pressing type pipe joint is other shapes such as hexagon, the mating surface of then going up compact heap 2 and following compact heap 3 is provided with corresponding hex shaped groove.
Operation principle:,, reach to the abundant compacting that compresses compression member in the working chamber, fastening by the roof pressure of hydraulic mandril 4 by hydraulic action.
Job step: 1, open compact heap 2, put into compression member; 2, will go up compact heap 2 fixes by the active pin shaft 9 and first latch 12 with caliper 1; 3, open hydraulic selector 6; 4, press down hydraulic handle 11 repeatedly, make hydraulic mandril 4 promote upwards compact heap 2 directions motion of compact heap 3 down; 5, after affirmation compresses, close hydraulic selector 6, open compact heap 2.
In addition to the implementation, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
