Description

A kind of agricultural jack

Technical field

The utility model relates to a kind of jacking system, particularly a kind of agricultural jack.

Background technology

Jack in process of production; Used by people through regular meeting, more existing field machines all need these machineries of jack pair to go up and down in the middle of the process of maintenance or maintenance; Existing common jack jacking system; Owing to much all be general-duty, use very inconveniently, adjustable height has goes back out of reach; After the time of using is long, be easy to damage, service life is short.

The utility model content

The utility model technical matters to be solved is the deficiency to prior art, and a kind of later-model agricultural jack is provided.To achieve these goals, the measure taked of the utility model:

A kind of agricultural jack; Comprise base and lifter, be fixedly connected with pole-climbing on the described base, the lifter setting is fixed in the pole-climbing; Have the fixed orifice of vertical arrangement in the pole-climbing; Inserted set pin in the fixed orifice, be connected with crank handle on the lifter, installed on the lifter and be connected with shears;

The integral body that described lifter and shears are formed in one;

The side of described lifter is provided with the labeling district;

Described crank handle is can drawing handle, in the joint that stretches bayonet lock is installed;

Described fixed orifice is oval-shaped circular hole;

The edge of the head of described set pin is the circular shape of trimming;

On the described lifter switch that reverses is installed;

The top of described pole-climbing is equipped with gib head;

The bottom of described crank handle is equipped with the pull back spring sheet;

The upper surface of described shears is provided with profile of tooth or waveform groove.

The beneficial effect of the utility model: practicality, productive costs is low, use, easy to carry, long service life, stable, adjustable height is high, and range of use is wide.

The specific embodiment

A kind of agricultural jack; Comprise base 9 and lifter 8, be fixedly connected with pole-climbing 7 on the described base 9, lifter 8 is provided with and is fixed in the pole-climbing 7; Have the fixed orifice 3 of vertical arrangement in the pole-climbing 7; Inserted set pin 2 in the fixed orifice 3, be connected with crank handle 6 on the lifter 8, installed on the lifter 8 and be connected with shears 5; The integral body that described lifter 8 and shears 5 are formed in one; The side of described lifter 8 is provided with labeling district 4; Described crank handle 6 is can drawing handle, in the joint that stretches bayonet lock 1 is installed; Described fixed orifice 3 is oval-shaped circular hole, to improve the load-carrying capacity of pole-climbing 7; The edge of the head of described set pin 2 is the circular shape of trimming, and it is free to advance or retreat in fixed orifice 3 when work to be beneficial to set pin 2; On the described lifter 8 switch that reverses is installed, makes the utility model when the up-down weight, can descend by the hole by rising on the hole again; The top of described pole-climbing 7 is equipped with gib head, so that the utlity model has the clamping function; The bottom of described crank handle 6 is equipped with the pull back spring sheet, so that crank handle 6 can be fixed in the pole-climbing 7 when not shaking; The upper surface of described shears 5 is provided with profile of tooth or waveform groove, so that the object that is gone up and down is difficult for slippage.

When using the utility model, at first put base 9, the mechanical registeration that needs are gone up and down is placed on the shears 5; Realize lifter 8 climbing in pole-climbing 7 through crank handle 6, thereby realize the purpose that jack goes up and down, when being elevated to the height that needs; Set pin 2 is inserted in the fixed orifice 3, play fixing effect, wherein go bulk processing on set pin 2 surfaces and the limit; During pull set pin 2, can not block, use safer; The integral body that lifter 8 and shears 5 are formed in one, weight capacity is stronger, long service life; The side of lifter 8 is provided with labeling district 4, can mark out easily the utility model can load-bearing numeral, adjustable height or other information, easy to use; Crank handle 6 is can drawing handle, bayonet lock 1 is installed, longer crank handle 6 in the joint that stretches; Make that to shake crank handle 6 more laborsaving; Wherein, behind the stretching crank handle 6, can fix the crank handle 6 of coming out that stretches through bayonet lock 1; Safe in utilization, thus the purpose of realization the utility model.

Wherein, the utility model is in the middle of the use of reality, and lifter can be used for drawing movement of objects under form is stood tall and upright in specific putting.

Those skilled in the art's simple change and replacement in this area all are within the protection domain of the utility model.
