Abstract
The utility model relates to an engineering machine operation lever, which is characterized in that a bending part is formed by joining an upper and a lower pipes through an angle adjusting lock sheet and a locking bolt pair, wherein a shaft pin with a handle is inserted into the upper section of pipe, a plurality of semi-circular shallow slots are arranged on the insertion part of the shaft pin in the radial direction according to the adjusting length, and steel balls inside corresponding holes of the upper section of pipe in the radial direction can be blocked inside any slot to adjust the insertion depth of the shaft pin with the handle so as to adjust the length. A locking cutting sleeve outside the upper section of pipe is used for locking the steel balls so as to prevent the play of the shaft pin.
Description
Affiliated field
The utility model relates to a kind of engineering machinery operating rod, and the driver especially can regulate operating rod length and use the operating rod at angle of inclination at the arrangement of levers of pilothouse maneuvering device running.
Background technology
Present known operating rod is "＜" shape pipe that curves certain angle, and last pipe joint end is by a handle, and following pipe joint client link is on controls.Because operating rod length and angle of inclination are being fixed, for the driver who is sitting on the driver seat, because height is different with custom separately, it is just not necessarily very comfortable to operate.
Summary of the invention
In order to overcome the defective that present operating rod can not be regulated, the utility model provides a kind of operating rod, can suitably regulate the operating rod at length and angle of inclination, solves to have the not good defective of operation comfort at present.
The utility model solves its technical matters, the technical scheme that is adopted is: by bending position above the former operating rod it is cut in two, respectively adorn a circular angle adjusting pin sheet that radially has the radial concavo-convex flank of tooth at the sub-intercept of 2-section pipe place up and down, there is a circular hole at the disk center.Angular setting sheet with the concavo-convex flank of tooth is lumped together.So because the plane flank of tooth is meshing with each other and can not skid, secondary fixing with clamping screw in the center pit as long as adjust the angle of two-section pipe up and down, this moment, the angle of inclination of operating rod just can satisfactory angle of inclination.The solution of length adjustment is, insert a pivot pin that has handle in last pipe joint upper end, need by regulating length on the external diameter of pivot pin insertion portion, some semicircle shallow slots of car separated by a distance, radially bore a pair of symmetrical aperture in the appropriate location at last pipe joint, can respectively put into a steel ball, when certain bar semicircle shallow slot on the pivot pin aligns aperture, steel ball just in time is stuck in this groove, do not make pivot pin the pipe in about play.Steel ball card is in the semicircle shallow slot of diverse location, and the handle height and position on the pivot pin also changes thereupon, so operating rod length is also just different.In order to make steel ball be fixed on correspondence position, on the cylindrical of last pipe joint, also should add the locking cutting ferrule of a band tapered bore, the tapered bore small end is on steel ball the time, just steel ball is pressed on the half dollar shallow slot of pivot pin, steel ball just can break away from the semicircle shallow slot when the big end of tapered bore is on the steel ball position, as long as big end internal diameter is slightly larger than the pivot pin external diameter and adds two diameter of the steel ball, pivot pin just can move axially in last pipe joint.But can stop steel ball from the hole of last pipe joint, to be deviate from.Locking cutting ferrule endoporus also should process together with last pipe joint external diameter on the screw thread of threads engaged.As long as the rotation lock cutting ferrule just can allow cone-shaped inner hole size end position correspondence on steel ball, just can finish the locking cutting ferrule pivot pin has been locked with the effect of decontroling like this.
The beneficial effects of the utility model are to adjust stick position according to driver individual's habit, and the driver is more comfortable in operating process, more humane, thereby improve working efficiency.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is external structure figure of the present utility model.
Fig. 2 is the longitudinal profile structural map of embodiment.
1. handles among the figure, 2. pivot pin is 3. gone up pipe joint, 4. steel ball, 5. locking cutting ferrule, 6. angular adjustment sheet, 7. the lock(ing) bolt pair is 8. descended pipe joint.
Embodiment
Among Fig. 1, connect with lock(ing) bolt secondary 7 between the angular adjustment sheet 6 at following pipe joint 8 and last pipe joint 3 two ends, the pivot pin 2 of a band handle 1 is inserted in last pipe joint 3 upper ends, and last pipe joint 3 outsides also have a locking cutting ferrule 5.
The diametric plane of the visible angular adjustment sheet 6 of Fig. 2 longitudinal profile structural map is to be with radial shaggy tooth, and two flank engagement are fixing with lock(ing) bolt secondary 7 together, and it is non-slip just can to guarantee that angular setting puts in place, positive lock.Inserted the pivot pin 2 of band handle 1 in addition in last pipe joint 3 upper ends, the semicircle shallow slot on the pivot pin 2 can preferably be not more than 1/3rd of steel ball 4 diameters according to regulating some its degree of depth of length car.Steel ball 4 is placed in the radial hole of pipe joint 3, and it is more reliable that symmetry is punched two steel ball 4 clip effects of placement usually.Know more that in order to illustrate the position of locking cutting ferrule 5 on steel ball 4 is respectively locking and relieving state among the figure.As long as rotation lock cutting ferrule 5 by cooperating the screw thread of going up on the pipe joint 3 with it, just can change the position of locking cutting ferrule 5 internal tapered holes on steel ball 4, pivot pin 2 was locked when locking cutting ferrule 5 cone-shaped inner hole small ends were pressed on the steel ball 4 in the use.The big end of cone-shaped inner hole on steel ball 4 positions the time pivot pin just can do axially-movable so that adjust length.So add two steel balls, 4 diameter steel balls 4 and can not deviate from because locking cutting ferrule 5 cone-shaped inner hole outside diameters are slightly larger than the pivot pin diameter, to guarantee the normal use of operating rod.
Claims (4)
1, the operating rod used of a kind of engineering machinery, have pivot pin and handle on the last pipe joint of 2-section pipe up and down, it is characterized in that, last pipe joint and following pipe joint are tied with the clamping screw duplicate invoice by the circular angle adjustment sheet in its end, the pivot pin of a band handle is inserted in last pipe joint upper end, last pipe joint radially is placed with steel ball in the corresponding aperture, and it is managed outer and is rotary with an endoporus is conical locking cutting ferrule, and locking cutting ferrule round taper hole two ends all should be able to be dropped on the steel ball.
