The first hinged vibrating boom of lever dolly, the middle part of first vibrating boom and the lever dolly are hinged, first shake
The rear end of bar is hingedly connected with the rear end of one second vibrating boom, also sets up between first vibrating boom and second vibrating boom
There is positioning static mechanism.
A stay hook is hinged in the middle part of first vibrating boom, be provided in the middle part of second vibrating boom with it is described solid
The hook fixed ring for determining hook cooperation, is provided with the first hinged shaft, the hook between first vibrating boom and the lever dolly
The front of first hinged shaft is arranged in fixed ring.
The positioning static mechanism includes that the first shake rod rear end is arranged in and contradicts towards the first of oblique upper oblique
Face.
The rear end of second vibrating boom is provided with second matched with first conflict inclined-plane and contradicts inclined-plane.
The rear end of second vibrating boom is provided with the hinged ear hinged with first vibrating boom, the hinged ear and institute
It states and is provided with the second hinged shaft between the second vibrating boom, the rear of second hinged shaft is arranged in second conflict inclined-plane.
The rear end of first vibrating boom is provided with the accommodation groove for accommodating the hinged ear.
The beneficial effects of the present invention are: dither arm of the invention, including successively hinged lever dolly, the first vibrating boom and
Second vibrating boom is additionally provided with positioning static mechanism between the first vibrating boom and the second vibrating boom, when operating, by the second shake
Bar rotation expansion, positions static mechanism for the first vibrating boom and the second vibrating boom and is locked into the strip under working condition, very
It is convenient；When idle, since the first vibrating boom and the second vibrating boom are hinged, so the two can be folded up, in this way
The length of entire dither arm is just shortened without stretching out other than locating machinery equipment, personnel is avoided to be not intended to wound caused by touching
Evil.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples, it should be noted that, in the description of the present invention,
The orientation or positional relationship of the instructions such as term " on ", "lower", "left", "right", "inner", "outside" be orientation based on the figure or
Positional relationship is merely for convenience of description of the present invention and simplification of the description, rather than the device or element of indication or suggestion meaning must
There must be specific orientation, construct and operate in a particular manner, therefore be not considered as limiting the invention.Term " the
One ", " second ", " third " etc. are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.
As shown in Figure 1, a kind of dither arm, hinged including the lever dolly 1 being vertically arranged and with lever dolly 1 first is trembled
Lever 2, the middle part of the first vibrating boom 2 and lever dolly 1 are hinged, and the rear end of the first vibrating boom 2 is hingedly connected with one second shake
The rear end of bar 3 is additionally provided with positioning static mechanism between first vibrating boom 2 and the second vibrating boom 3, and when operating, second is trembled
The rotation expansion of lever 3, positions static mechanism for the first vibrating boom 2 and the second vibrating boom 3 and is locked into the strip under working condition,
It is very convenient；When idle, since the first vibrating boom 2 and the second vibrating boom 3 are hinged, so the two can fold
Come, thus shortens the length of entire dither arm without stretching out other than locating machinery equipment, personnel is avoided to be not intended to touch
Caused by injure.
In the present embodiment, in order to by folded first vibrating boom 2 and the second vibrating boom 3 preferably fix without
It shakes, the middle part of the first vibrating boom 2 is hinged with a stay hook 4, and the middle part of the second vibrating boom 3 is provided with and the cooperation of stay hook 4
Fixed ring 5 is hooked, the first hinged shaft 6 is provided between the first vibrating boom 2 and lever dolly 1, hooks the setting of fixed ring 5 in the first hinge
The front of axis 6, such first vibrating boom 2 and the second vibrating boom 3 are hooked by stay hook 4 after folding and hook fixed ring 5.
It positions there are many static mechanism set-up modes, such as with bolt and nut by the first vibrating boom 2 and the second vibrating boom 3
Sealed fixation, or again with the form etc. being clasped, in the present embodiment, positioning static mechanism includes that setting is trembled first
2 rear end of lever and towards oblique upper first contradict inclined-plane 7, in this way the second vibrating boom 3 be unfolded when, the tail of the second vibrating boom 3
End is directly shelved conflict from top and is contradicted on inclined-plane 7 first, and structure is simple, does not have to other component, and use cost is low.
Further, for the second vibrating boom 3 after preferably firm expansion, the rear end of the second vibrating boom 3 be provided with
The second conflict inclined-plane 8 that first conflict inclined-plane 7 matches, after expansion, the second conflict inclined-plane 8 is all fitted in the first conflict inclined-plane
7, contact surface is big, will not shake.
Further, the rear end of the second vibrating boom 2 is provided with the hinged ear 9 hinged with the first vibrating boom 1, hinged ear 9 with
The second hinged shaft 10 is provided between second vibrating boom 3, the rear of the second hinged shaft 10, the first shake is arranged in the second conflict inclined-plane 8
The rear end of bar 1 is provided with the accommodation groove 11 of accommodating hinged ear 9, and when folding, hinged ear 9 is embedded in accommodation groove 11,.
The working principle of the invention is: when operating, the second vibrating boom 3 being rotated and is unfolded, second contradicts all patches of inclined-plane 8
Merging is shelved on the first conflict inclined-plane 7, and the first vibrating boom 2 and the second vibrating boom 3 are locked into the strip under working condition at this time,
It is very convenient；When idle, the second vibrating boom 3 of rotation is packed up, and is pulled out stay hook 4 and is hooked hook fixed ring 5,
The first vibrating boom 2 and the second vibrating boom 3 are folded up at this time, thus shorten the length of entire dither arm without stretching out
Other than the machinery equipment at place, personnel is avoided to be not intended to injury caused by touching.
