Abstract
The utility model provides a gear type jack which comprises a gear set, a jack cylinder, a push rod, a crank handle, a one-way stop pin and a spring. The gear type jack is technically characterized in that the crank handle and a gear 7 adopt an coaxial structure, a gear 1 and a gear 2 adopt a coaxial gear set, a gear 3 and a gear 4 adopt a coaxial gear set, and a gear 5 and a gear 6 adopt a coaxial gear set. The gear 7 is meshed with the gear 6, the gear 6 drives the gear 5 to move during the running process, the gear 5 is meshed with the gear 4, the gear 4 drives the gear 3 to move during the running process, the gear 3 is meshed with the gear 2, the gear 2 drives the gear 1 to move during the running process, the gear 1 is meshed with a thread on an upright column for the jack, and the gear 1 is used for pushing the push rod to move upwards during the rotating process to jack the heavy object. Compared with the traditional hydraulic jack, the utility model has the advantages that the requirement of sealing performance is not required, the arm ratio between the driving force arm and the driven force arm is high, the effective jacking to the heavy object can be realized, the jacking speed and the efficiency of the push rod are high, and the operation is flexible and convenient.
Description
Technical field:
The utility model relates to a kind of jack, particularly a kind of gear type jack.
Technical background:
At present, the most of jacks of China all are the fluid pressure type jacks.This fluid pressure type jack has following characteristics: one, high to the sealing requirements of cylinder body; Two, need special liquid (as wet goods) as pressure transmission medium; Three, when work, by carrying, press handle repeatedly, and utilize the one-way sealing sheet to realize the nonreturn flow of liquid, thereby realize the transmission of pressure.Its weak point is, one, cylinder body and inner each parts want strict seal, because during work, cylinder interior produces very big pressure, so, in case poorly sealed, can't realize effective transmission of pressure, the cylinder bar can't jacking, and in frequent use, because its work characteristics, the mechanical wear of some parts is unavoidable, so close property is difficult to guarantee; Two, hydraulic jack is to utilize the jacking of hydraulic principle realization to weight, manually carries, presses handle to exert pressure repeatedly owing to rely on, so the cylinder bar promotes slowly, jacking efficient is low.
Summary of the invention:
The utility model is the deficiency that exists in the above-mentioned technology, and a kind of gear type jack is provided, and this jack does not have sealing requirements, main, big by the power arm ratio, can realize the effective jacking to weight, push rod jacking speed is fast, efficient is high, flexible operation, convenient.
The purpose of this utility model is to realize like this, jack is made up of gear cluster, jack cylinder, push rod, wind and unidirectional fixing pin and spring, it is characterized in that: rocking handle is coaxial integrative-structure with gear 7, gear 1 is coaxial one gear cluster with gear 2, gear 3 is coaxial one gear cluster with gear 4, gear 5 is coaxial one gear cluster with gear 6, and its middle gear 1,3,5 is a miniature gears, and gear 2,4,6 is a big gear wheel.Gear 7 and gear 6 engagements, driven gear 5 motions in the time of gear 6 motions, gear 5 and gear 4 engagements, driven gear 3 motions in the time of gear 4 motions, gear 3 and gear 2 engagements, driven gear 1 motion in the time of gear 2 motions, the screw-threaded engagement on the column of gear 1 and jack, gear 1 promotes to move the jack-up weight on the jack push rod when rotating.
This uses later-model working process is such, applies moment by wind, utilizes the gear cluster carry-over moment, and the stuck at any time push rod of unidirectional fixing pin prevents that it from sinking, and realizes the short distance jacking to weight.After jacking work is finished, move the button of removing above the unidirectional fixing pin, can make the push rod playback.Jack is made by steel material, can make the jack of different model according to this novel each parts equal proportion according to the Different Weight of jacking thing.
More traditional fluid pressure type jack, the utility model does not have sealing requirements, and is main, big by the power arm ratio, can realize the effective jacking to weight, and push rod jacking speed is fast, efficient is high, flexible operation, convenient.
Description of drawings:
Fig. 1 is a lateral sectional view of the present utility model
Fig. 2 is a forward section-drawing of the present utility model
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further specified.
By Fig. 1-2 as can be known, shake handle 8, driven gear 7 rotates, gear 7 driven gears 6 rotate, gear 5 passive rotation coaxial with gear 6, and driven gear 4 rotates, gear 3 passive rotation coaxial with gear 4, driven gear 2 rotates, gear 1 passive rotation coaxial with gear 2, thus drive push rod 9 upwards jackings.When push rod 9 promoted, increment withstood on the inclined-plane of unidirectional fixing pin 10, made it to shrink, and after increment surpasses the end face of fixing pin 10, because the effect of spring 11 makes fixing pin 10 playback, and was against the tooth nest of push rod 9.Along with the continuous jacking of push rod 9, fixing pin 10 does not shrink disconnectedly, ejects.After jacking work is finished, spur the button of removing on the fixing pin, make it to shrink, the backward rotation rocking handle, push rod 9 can playback.
Embodiment 1: driving wheel is respectively with follower arm of force ratio: rocking handle 8 is 3:1 with the arm of force ratio of gear 7; Gear 6 is 3:2 with the arm of force ratio of gear 5; Gear 4 is 2:1 with the arm of force ratio of gear 3; Gear 2 is 2:1 with the arm of force ratio of gear 1, and promptly theoretically, the active arm of force: by power arm is 18:1, and jacking weight is bigger.Gear 1 rotates a circle, only needs wind to rotate six circles.
