Abstract
The utility model provides a hydraulic telescopic connecting rod, which relates to a hydraulic device. The hydraulic telescopic connecting rod comprises a hydraulic cylinder, wherein a hydraulic rod is connected onto the hydraulic cylinder. The hydraulic telescopic connecting rod is characterized in that a connecting rod is movably connected onto the hydraulic rod, the other end of the connecting rod is connected onto the telescopic connecting rod, the telescopic connecting rod is fixedly arranged on a shaft, an unthreaded hole is formed in the connecting rod, and a support rod is inserted into the unthreaded hole. The hydraulic telescopic connecting rod has the advantages that the structure is simple, the design is reasonable, the existing structure that the hydraulic rod is directly connected onto the telescopic connecting rod is changed, the connecting rod is additionally arranged between the hydraulic rod and the telescopic connecting rod, the connecting rod swings to and fro through the support rod, and the swinging amplitude of the telescopic rod is increased, so the to-and-fro rotating range of the shaft is larger, and the effect is enhanced.
Description
Technical field:
The utility model relates to a kind of hydraulic pressure installation, is specifically related to a kind of hydraulically extensible connecting rod.
Background technique:
In prior art, oil hydraulic cylinder connecting fluid depression bar, hydraulic rod is directly connected on shrinking connecting-rod, by hydraulic rod, stretch and drive shrinking connecting-rod to swing back and forth, thereby band moving axis rotates, shrinking connecting-rod amplitude of fluctuation is little, and axle rotating effect is not obvious, needs hydraulic rod increasing collapsing length to realize axle and significantly rotates.
Model utility content:
Technical problem to be solved in the utility model is to overcome the defect of prior art, provides a kind of identical collapsing length lower shaft rotation amplitude larger hydraulically extensible connecting rod.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of hydraulically extensible connecting rod, comprise oil hydraulic cylinder, on oil hydraulic cylinder, be connected with hydraulic rod, it is characterized in that: on described hydraulic rod, be connected with a connecting rod, the connecting rod the other end is connected on shrinking connecting-rod, shrinking connecting-rod is fixed on axle, and described connecting rod is provided with unthreaded hole, is inserted with a pole in unthreaded hole.
Described unthreaded hole is arranged near on the connecting rod front end of hydraulic rod, the hydraulic rod identical length of stretching, the amplitude maximization that connecting rod swings, the connecting rod amplitude that swings back and forth is larger, the amplitude of fluctuation of shrinking connecting-rod is also larger, thereby make axle, in the situation that the flexible identical length of hydraulic rod is rotated, reaches maximization.
On the pole of described shrinking connecting-rod both sides, be inserted with locating stud, avoid shrinking connecting-rod to occur sliding, make shrinking connecting-rod be stabilized in local a rotation, be better with moving axis to rotate.
The utility model is simple in structure, reasonable in design, changing hydraulic rod in the past is directly connected on shrinking connecting-rod, in the middle of hydraulic rod and shrinking connecting-rod, have additional a connecting rod, connecting rod swings back and forth by pole, increased the amplitude of fluctuation of shrinking connecting-rod, slewing area is larger back and forth to make axle, strengthens effect.
Accompanying drawing explanation:
Fig. 1 is prior art structural representation;
Fig. 2 is the utility model structural representation;
Wherein: 1: oil hydraulic cylinder; 2: hydraulic rod; 3: connecting rod; 4: shrinking connecting-rod; 5: axle; 6: unthreaded hole; 7: pole; 8: locating stud.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1 in prior art, oil hydraulic cylinder 1 connecting fluid depression bar 2, hydraulic rod 2 is directly connected on shrinking connecting-rod 4, by the flexible shrinking connecting-rod 4 that drives of hydraulic rod 2, swing back and forth, thereby band moving axis 5 rotates, shrinking connecting-rod 4 amplitude of fluctuation are little, and axle 5 rotating effects are not obvious, need hydraulic rod 2 increasing collapsing lengths to realize axle 5 and significantly rotate.
A kind of hydraulically extensible connecting rod as shown in Figure 2, comprise oil hydraulic cylinder 1, on oil hydraulic cylinder 1, be connected with hydraulic rod 2, on hydraulic rod 2, be connected with a connecting rod 3, connecting rod 3 the other ends are connected on shrinking connecting-rod 4, shrinking connecting-rod 4 is fixed on axle 5, and wherein connecting rod 4 is provided with unthreaded hole 6, is inserted with a pole 7 in unthreaded hole 6.
Wherein unthreaded hole 6 is arranged near on connecting rod 3 front ends of hydraulic rod 2, the flexible identical length of hydraulic rod 2, the amplitude maximization that connecting rod 3 swings, connecting rod 3 amplitude that swings back and forth is larger, the amplitude of fluctuation of shrinking connecting-rod 4 is also larger, thereby make axle 5, in the situation that the flexible identical length of hydraulic rod 2 is rotated, reaches maximization.
Wherein on the pole 7 of shrinking connecting-rod 4 both sides, be inserted with locating stud 8, avoid shrinking connecting-rod 4 to occur sliding, make shrinking connecting-rod 4 be stabilized in local a rotation, be better with moving axis 5 to rotate.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
