Utility model content
The utility model for prior art Problems existing, the interlock adjustable balanced type lifting screw providing a kind of structure simple, easy to operate, realize ground not at ordinary times two jacks land, to ensure the balance quality of jack simultaneously.
The purpose of this utility model realizes like this, a kind of interlock adjustable balanced type lifting screw, comprise the active lifting screw of synchronization lifting and driven lifting screw, described active lifting screw side is provided with the horizontally disposed imput shaft driven by handle one, described active lifting screw opposite side is connected with output shaft, horizontally disposed driven shaft is provided with in described driven lifting screw, described active lifting screw and driven lifting screw are by universal driving shaft synchronized links, described imput shaft and driven shaft drive initiatively lifting screw and driven lifting screw dipping and heaving respectively by bevel drive parts, being connected with between described driven shaft and universal driving shaft can clutch shaft in axial sliding, the axle head of described clutch shaft is connected by the slotting key clutch cooperatively interacted with the axle head of driven shaft, described clutch shaft periphery compresses and is provided with the Compress Spring making clutch shaft and the tight grafting of driven shaft, described clutch shaft is provided with shift fork near the periphery cooperation of inserting key, described shift fork is connected with the housings support of driven lifting screw by shift fork bearing, described universal driving shaft axle head is set in the periphery of clutch shaft axle head, and run through clutch shaft be fixedly connected with the bearing pin of universal driving shaft by radial, the pin shaft hole that described clutch shaft coordinates with bearing pin is long waist shaped through hole.
Interlock adjustable balanced type lifting screw structure of the present utility model, initiatively lifting screw is connected by universal driving shaft with driven lifting screw, synchronization lifting motion is realized by driving handle one, when the leg running into ground unfairness two jack can not land simultaneously, only shift fork need be stirred, the driven shaft of driven lifting screw is separated with clutch shaft, swinging handle one simultaneously, regulate the height of landing leg initiatively revolving spiral shell jack that initiatively lifting screw and driven lifting screw leg are landed simultaneously, then unclamping shift fork makes the slotting key grafting of clutch shaft and driven shaft lock, continue the lift operation that operating handle one completes jack, thus realize lifting screw and land when ground injustice simultaneously, ensure lifting balance, available protecting lifting screw, and extend its service life.
For being convenient to regulate the relative lift height of initiatively lifting screw and driven lifting screw further, the axle head of described driven shaft is provided with handle two.In this structure, in jack lifting, when meeting ground not at ordinary times, operating personal only need forward driven lifting screw side to, a hand-lifting moves fork, and clutch shaft is separated with driven shaft, the hand fixed handle two of another, the lift height of the driven lifting screw of independent adjustment, be adjusted to two jacks to land simultaneously, then unclamp shift fork, get back to initiatively lifting screw position, continue operation synchronization lifting two jack by handle one, realize the synchronous steadily lifting of two jacks.This structure can realize a people just energy synchronous operation two jack synchronization action, realizes flat hidden lifting.
For ease of stirring shift fork, the hull outside being provided with that described shift fork stretches out driven lifting screw is convenient to stir the external part that shift fork swings along shift fork bearing.
For ease of the mounting or dismounting of handle, described handle one and handle two are connected respectively by quick-inserting structure is split type with imput shaft and driven shaft respectively.
