Abstract
The utility model belongs to service vehicles, in particular to a rocker arm lifting mechanism of a service vehicle, which is characterized in that a lifting mechanism base is formed by welding square pipes and metal plates; lugs and limiting stoppers are arranged on both sides of the base; limiting slots are formed in the limiting stoppers; the lugs on each side are an upper lug and a lower lug; the limiting stoppers on each side are an upper limiting stopper and a lower limiting stopper; the upper lug and the upper limiting stopper are welded on the middle pallet of the service vehicle; the lower lug and the lower limiting stopper are welded on the base; one end of a hinge is rotationally fixed with the upper lug; the other end of the hinge slides in the limiting slot of the limiting stopper; one end of another hinge is rotationally fixed with the lower lug; the other end of the latter hinge is fixed in the limiting slot of the upper limiting stopper through a push rod and can slide in the limiting slot; holes are formed in the middles of the hinges on two sides of the base; screw shafts penetrate into the holes; push rods are mounted in the limiting slots on two sides of the base, so that mechanisms on two sides are connected to a double-side four-bar mechanism. As the rocker arm lifting mechanism adopts the double-side four-bar mechanism, the lifting is smooth; the operation is simple; requirements of various specific industries are met.
Description
Technical field
The utility model belongs to the servicer class, specifically a kind of servicer rocker lifter mechanism.
Background technology
Job that requires special skills at present and specific industry increase, use to servicer is more and more, operating needs also improves constantly, as for maintenance service industry and all types of vehicle, in different places, regulate voluntarily adjustable height according to need of work, and the structure of servicer is reasonable not enough at present, stablizes not smooth and easy as the lifting of servicer, the balance of servicer is good not, so that the service efficiently of can not providing convenience in maintenance process.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of servicer in lifting process, to stablize the servicer rocker lifter mechanism smooth and easy, that balance is good.
The technical scheme that the utility model adopts is:
A kind of servicer rocker lifter mechanism, comprise collapsible rocking bar, screw shaft, hinge, journal stirrup, limiting stopper, square tube, metal sheet, bolt, catch bar, it is characterized in that: square tube and metal sheet are welded into the lifting mechanism base, base is welded on four square tube supporting rods, the base both sides are equipped with journal stirrup and limiting stopper, limiting stopper is with position-limited trough, every side journal stirrup and limiting stopper are divided into upper and lower two parts, upper journal and upper limit position block are welded on the intermediate tray of servicer, down journal and lower position block are welded on base, hinge one end and upper journal fixedly are slew mode, the other end slides in the position-limited trough of lower position block, another root hinge one end and down journal fixedly are slew mode, the other end is fixed on by catch bar in the position-limited trough of upper limit position block and slides, all perforates in the middle of the hinge of both sides, penetrate screw shaft, push rod is installed in the position-limited trough of both sides, make both sides mechanism connect into the bilateral four-bar linkage, push rod connects collapsible rocking bar, be assemblied in position-limited trough.
The utility model adopts the bilateral four-bar linkage to connect, and by hand moving collapsible rocking bar, is seesawed, and promotes the mode of four-bar linkage slip rotation, reaches the purpose of steady lifting.When collapsible rocking bar is made clickwise, be assemblied in catch bar in position-limited trough to front slide, mechanism is propradation, and when collapsible rocking bar was made left-hand revolution, the catch bar be assemblied in position-limited trough slided backward, and mechanism is the decline state.
The utility model rocker lifter mechanism has adopted the bilateral four-bar linkage that balance is good, mode of motion with four-bar linkage slip rotation reaches stable, smooth and easy lifting, simple to operate, convenient and practical, belonging to light-duty mobile liftable instrument, is the first-selected instrument of Information Mobile Service work, meets the demand of various specific industries.
The accompanying drawing explanation
Fig. 1 the utility model rocker lifter mechanism structure schematic diagram.
The collapsible rocking bar assembling of Fig. 2 schematic diagram.
Fig. 3 is catch bar welding schematic diagram.
Fig. 4 is hinge single-piece schematic diagram.

The specific embodiment
As Figure 1-4, servicer rocker lifter of the present utility model mechanism, comprise collapsible rocking bar 1, screw shaft 6, hinge 5, journal stirrup 9, limiting stopper, square tube 3, metal sheet 7, bolt 8, catch bar 4, it is characterized in that: square tube 3 and metal sheet 7 are welded into the lifting mechanism base, base is welded on four square tube supporting rods, the base both sides are equipped with journal stirrup 9 and limiting stopper, limiting stopper is with position-limited trough 2, every side journal stirrup 9 is divided into upper and lower two parts with limiting stopper, upper journal and upper limit position block are welded on the intermediate tray of servicer, down journal and lower position block are welded on base, hinge 5 one end and upper journal fixedly are slew mode, the other end is fixed on by catch bar 4 in the position-limited trough of lower position block and slides, another root hinge 5 one ends and down journal fixedly are slew mode by bolt 8, another stomidium slides in the position-limited trough of upper limit position block, all perforates in the middle of the hinge of both sides, penetrate screw shaft 6, catch bar 4 is installed in the position-limited trough of both sides, make both sides mechanism connect into the bilateral four-bar linkage, catch bar 4 connects collapsible rocking bar 1, be assemblied in position-limited trough 2.
The utility model journal stirrup 9 and slip position-limited trough 2 position of weld, keep certain planeness, the distortion of can not tilting, otherwise can cause unstable the having some setbacks property of four-bar linkage, utilize fixture, cubing is pressed drawing and is measured critical size, guarantee its precision, the plane balancing degree, make product qualified, by setting up successive check, thereby in the stability that has guaranteed qualitatively rocker mechanism and smoothness.
As shown in Figure 5, the utility model rocker lifter mechanism is by the assembly drowing in car load, and the rotary folding type rocking bar, can realize steady lifting.
