Description

A kind of hydraulic jack with rapid pipe joint
Technical field
The utility model relates to a kind of hydraulic jack, is specifically related to a kind of hydraulic jack with rapid pipe joint, belongs to mechanical field.
Background technique
Hydraulic jack is hydraulic actuator hydraulic energy being changed into mechanical energy, do straight reciprocating motion.Its structure is simple, and reliable operation, when realizing to-and-fro motion with it, can remove speed reducer from, and not have movement clearance, stable movement, therefore be used widely in the hydraulic system of various machinery.The pressure reduction on oil hydraulic cylinder ouput force and piston effective area and both sides thereof is directly proportional.Existing hydraulic jack and operation element generally adopt bolt or middleware to be connected, and the speed that couples together is comparatively slow, and insecure, affects working efficiency.
Summary of the invention
The utility model generally adopts bolt or middleware to be connected to solve existing hydraulic jack and operation element, and the speed that couples together is comparatively slow, and insecure, affects the problem of working efficiency, and then proposes a kind of hydraulic jack with rapid pipe joint.
The utility model is the technological scheme taked that solves the problem: the utility model comprises cylinder body and piston rod, one end of piston rod is inserted in one end of cylinder body, the other end of piston rod is provided with fast connection mechanism, described fast connection mechanism comprises snap ring, first Returnning spring, lock sleeve, second Returnning spring, connecting ring and two connecting rods, snap ring, first Returnning spring, lock sleeve is sleeved on the outer side wall of piston rod to the other end successively by one end of piston rod, and snap ring is fixedly connected with the outer side wall of piston rod, lock sleeve can move linearly along piston rod, two connecting rod side by side parallel are arranged, one end and the connecting ring of each connecting rod are rotationally connected, connected by the second Returnning spring between two connecting rods, the other end of each connecting rod is provided with the chuck matched with the draw-in groove on piston rod the other end outer side wall.
The beneficial effects of the utility model are: 1, the utility model can realize being connected and dismounting with the quick of operation element with piston rod by quick-connect machanism, improve speed more than 20% than original Placement; 2, adjusting bolt of the present utility model and regulator plate enable the attachment hole on connection otic placode adapt to the pin of various diameter, and ensure that the firm of joint, avoid shaking during work.
[ accompanying drawing explanation]
Fig. 1 is overall structure schematic diagram of the present utility model.
[ embodiment]
Embodiment one: composition graphs 1 illustrates present embodiment, described in present embodiment, a kind of hydraulic jack with rapid pipe joint comprises cylinder body 1 and piston rod 2, one end of piston rod 2 is inserted in one end of cylinder body 1, the other end of piston rod 2 is provided with fast connection mechanism, described fast connection mechanism comprises snap ring 3, first Returnning spring 4, lock sleeve 5, second Returnning spring 6, connecting ring 7 and two connecting rods 8, snap ring 3, first Returnning spring 4, lock sleeve 5 is sleeved on the outer side wall of piston rod 2 by one end of piston rod 2 to the other end successively, and snap ring 3 is fixedly connected with the outer side wall of piston rod 2, lock sleeve 5 can move linearly along piston rod 2, two connecting rod 8 side by side parallel are arranged, one end and the connecting ring 7 of each connecting rod 8 are rotationally connected, connected by the second Returnning spring 6 between two connecting rods 8, the other end of each connecting rod 8 is provided with the chuck 8-1 matched with the draw-in groove 2-1 on piston rod 2 the other end outer side wall.
Embodiment two: composition graphs 1 illustrates present embodiment, a kind of hydraulic jack with rapid pipe joint described in present embodiment also comprises and connects otic placode 9, adjusting bolt 10 and regulator plate 11, connect the other end that otic placode 9 is fixedly mounted on cylinder body 1, regulator plate 11 is arranged on and connects on otic placode 9 in attachment hole 9-1, and adjusting bolt 10 is connected with regulator plate 11 through the outer side wall connecting otic placode 9.Other composition and annexation identical with embodiment one.
working principle
During installation, connecting ring 7 is connected with operation element, promoting lock sleeve 5 to cylinder body 1 side makes on piston rod 2 two draw-in groove 2-1 expose, chuck 8-1 on two connecting rods 8 respectively correspondence is installed in two draw-in groove 2-1, unclamp lock sleeve 5, lock sleeve 5 is sleeved on the outer side wall of piston rod 2 at the promotion of the first Returnning spring 4 two the chuck 8-1 that decline, and so realizes piston rod 2 and is connected with the quick of operation element; When the other end of cylinder body 1 is connected with operation element, the connection pin of operation element is inserted in the attachment hole 9-1 on connection otic placode 9, rotates adjusting bolt 10 until regulator plate 11 will connect pin compression, complete connection.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., be all included within protection domain of the present utility model.
