Description
Technical field
The present invention relates to a kind of safe axis for quick connector and a kind of quick connectors.
Background technology
Excavator quick connector is a kind of product that can realize quick, the efficient replacement excavator accessory of excavator, special
It is not the occasion that accessory is frequently replaced in some needs, quick connector can save 10 times of replacing construction or more, substantially increase
The effective time of excavator, use extremely important effect to engineering construction of the machine.
Now, excavator-type shovel clamshell excavator be difficult to using the centre-to-centre spacing of other accessories it is identical；Quick connector
Safe axis hole is generally set on the connector body of the connecting pin of movable hook, and movable hook is equipped with the notch passed through for safe axis；
Since the position of the safe axis hole of quick connector can only be adapted with a kind of centre-to-centre spacing, if the position of safe axis hole setting is applicable in
In centre-to-centre spacing be 480cm accessory, then for centre-to-centre spacing be less than 480cm accessory, safe axis is not installed, for center
Away from the accessory more than 480cm, safe axis does not reach movable hook, two kinds of situations, and safe axis does not have corresponding safety effect；
Above-mentioned two situations, safe axis cannot share the stress of oil cylinder simultaneously, and oil cylinder can all be constantly in and bear larger load
Under the operating mode of lotus, the thing of oil cylinder fracture frequently occurs, this not only greatly improves the cost of oil cylinder, but also seriously delays
The use of excavator, wastes the plenty of time.
Utility model content
The utility model is directed to above deficiency of the prior art, provides a kind of safe axis for quick connector and soon
Fast connector.
The technical solution that the utility model solves above-mentioned technical problem is as follows：A kind of safe axis for quick connector,
The safe axis includes head and bar portion, and the bar portion is included equipped with the smooth tapered rod of externally threaded cylindrical bar and surface.
The advantageous effect of safe axis is in the utility model：Suitable for different types of quick connector so that quickly connect
Device is connect, when capturing the accessory of different centre-to-centre spacing, the conical surface of safe axis can be installed and compress movable hook.
The utility model further relates to a kind of quick connector, and including connector body, the connector body is equipped with peace
Holoaxial hole, the safe axis hole are threaded hole, and safe axis is equipped in the safe axis hole, and the safe axis uses above-mentioned peace
Holoaxial.
The advantageous effect of quick connector in the utility model：When capturing the accessory of different centre-to-centre spacing, the conical surface of safe axis
It can install and compress movable hook, be not in that safe axis or the inoperative situation of safe axis, safe axis energy are not installed
The load of oil cylinder is enough shared, reduces the occurrence probability of oil cylinder fracture, has saved cost, improve quick connector uses the longevity
Life.
Further, the lower edge front end of the connector body is equipped with stay hook, after the lower edge of the connector body
End is hinged with movable hook, further includes hydraulic cylinder, and the hydraulic cylinder includes cylinder sleeve and piston rod, the cylinder sleeve and the connection
Device ontology is hinged, and the piston rod is hinged with movable hook；The lower end of the movable hook is equipped with the big notch being axially adapted to accessory,
Upper end is equipped with the small gap being adapted with the safe axis, and the safe axis hole is adapted with the small gap.
Description of the drawings
Fig. 1 is the structure diagram of the safe axis in the utility model；
Fig. 2 is the structure diagram (not installing safe axis in figure) of the quick connector in the utility model；
Structure diagrams (in figure omit oil cylinder) of the Fig. 3 for the quick connector after safe axis is installed in the utility model；
Fig. 4 is the front view of quick connector in the utility model；
In the accompanying drawings, the list of designations represented by each label is as follows：1st, safe axis, 1-1, head, 1-2, external screw thread
Cylindrical bar, 1-3, tapered rod, 2, connector body, 3, stay hook, 4, oil cylinder, 4-1, cylinder sleeve, 4-2, piston, 5, movable hook, 5-
1st, small gap, 5-2, big notch.
Specific embodiment
The principle and feature of the utility model are described below in conjunction with attached drawing, example is served only for explaining this practicality
It is novel, it is not intended to limit the scope of the utility model.
As shown in Figs 1-4, a kind of safe axis for quick connector, the safe axis 1 include head 1-1 and bar portion,
The bar portion is included equipped with externally threaded cylindrical bar 1-2 and surface smooth tapered rod 1-3.
The utility model further relates to a kind of quick connector, and including connector body 2, the connector body 2 is equipped with
Safe axis hole 6, the safe axis hole 6 are threaded hole, are equipped with safe axis 1 in the safe axis hole 6, the safe axis 1 uses
Above-mentioned safe axis 1；The lower edge front end of the connector body 2 is equipped with stay hook 3, the lower edge of the connector body 2
Rear end is hinged with movable hook 5 (thinking accessory in lower end, movable hook 5 and stay hook 3 are all disposed within the lower end of connector body), also
Including hydraulic cylinder 4, the hydraulic cylinder 4 includes cylinder sleeve 4-1 and piston rod 4-2, the cylinder sleeve 4-1 and the connector body
2 is hinged, and the piston rod 4-2 is hinged with movable hook 5；The lower end of the movable hook 5 is equipped with the big notch being axially adapted to accessory
5-2, upper end are equipped with the small gap 5-1 being adapted with the safe axis 1, and the safe axis hole 6 is fitted with the small gap 5-1 phases
Match.
The operating principle of the utility model is as follows：
When needing excavator connecting with accessory (such as Excavating bucket), there are front axle and rear axle on accessory.Piston 3 extends, and pushes away
Dynamic movable hook 5 rotates, and the big notch 5-2 on movable hook holds firmly rear axle；In order to safer, manually two safe axis 1 are divided
It not from 2 both sides of connector body, is symmetrically screwed into and is inserted into safe axis hole 6, for different centre-to-centre spacing, safe axis is screwed into distance not
Together, the conical surface of the tapered rod 1-3 of safe axis 1 can compress the small gap 5-1 on movable hook, share the load of oil cylinder 4,
It can be suitable for the accessory of different centre-to-centre spacing.
If as shown in figure 4, when not using the technical program, the centre-to-centre spacing of the accessory captured at this time is proper, pacifies at this time
Holoaxial can be loaded onto, and can compress small gap 5-1, the load for sharing oil cylinder；If the accessory centre-to-centre spacing of crawl is smaller, activity
Hook 5 can be in and rotate counterclockwise the position of a bit, at this point, safe axis is not installed；If the centre-to-centre spacing of accessory promptly is larger,
Movable hook 5 is in and rotates clockwise the position of a bit, at this point, safe axis may not work, it is also possible to not install, can not
Safety effect, while either which kind of form are played, is all that the piston rod of oil cylinder bears alone load, stress is larger, easy fracture.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
