The present invention is for the solution technical scheme that is used of its technical problem:
A kind of piston retention mechanism, it includes lifter plate, bearing and piston, and the lifter plate bottom is semicircle shape structure, Its middle-end is rectangular structure, and its upper end is rectangular structure, and its upper end is vertically arranged with its middle-end, the bearing with it is described Piston is vertically arranged, and the bearing is located at the upper end of the piston, and the piston is cube structure or cylindrical structural, inside it It is hollow-core construction, its upper end is provided with the first gap, the shape of first gap is consistent with the shape of the piston, the piston Right-hand member be provided with the second gap, connecting rod is connected with by second gap, the connecting rod front end be chondritic, its middle-end and Rear end constitutes sector structure, and the first opening position in the piston upper end is connected with piston adjustment axle, and the piston adjusts the shape of axle Shape is consistent with the shape of first gap, and the lower semisection of piston adjustment axle is in the inside of the piston, and its upper semisection is naked It is exposed at the upper end of the piston.
Also include being arranged on the axle sleeve on the piston adjustment axle top, the axle sleeve is wrapped in the top that the piston adjusts axle End, is provided with small locking nut below the axle sleeve, and the small locking nut has two, adjusts axle positioned at the piston respectively Both sides, be provided with adjustment swivel nut below the small locking nut, the adjustment swivel nut be two, respectively positioned at the piston Adjust the both sides of axle.
Further technical scheme of the invention is that big locking nut is provided with above the bearing, the big locking screw Mother has two, and it is cylindrical structural, and the big locking nut is located at the both sides that the piston tightly adjusts axle respectively.In the piston Locking nut is provided with the right side of adjustment axle, the locking nut is fixed on the upper end of the piston by rotation, and in the locking Clamping screw is connected with nut, the clamping screw is used in combination with the locking nut.The piston adjustment axle lower semisection Length is the height and the piston upper end thickness sum of the internal piston hollow-core construction.
The advantage of the invention is that:The piston retention mechanism adjusts axle to adjust the length of internal piston cavity by piston Degree, so as to produce different power when ensureing that connecting rod rotates up and down, improves operating efficiency, and the piston retention mechanism passes through lifter plate The height of piston can be adjusted, facilitates operating personnel to use in a variety of contexts.
Brief description of the drawings
Fig. 1 is a kind of structural representation of piston retention mechanism proposed by the present invention.
Wherein:1st, lifter plate, 2, bearing, 3, piston, 4, connecting rod, 5, piston adjustment axle, 6, axle sleeve, 7, small locking nut, 8th, swivel nut is adjusted, 9, big locking nut, 10, locking nut, 11, clamping screw.
Specific embodiment
For technological means, creation characteristic, reached purpose and effect for making present invention realization are easy to understand, with reference to Specific embodiment, is expanded on further the present invention.
As shown in figure 1, a kind of piston retention mechanism proposed by the present invention, it includes lifter plate 1, bearing 2 and piston 3, institute The bottom of lifter plate 1 is stated for semicircle shape structure, its middle-end is rectangular structure, its upper end is rectangular structure, and its upper end and its Middle-end is vertically arranged, and the bearing 2 is vertically arranged with the piston 3, and the bearing 2 is located at the upper end of the piston 3, the piston 3 is cube structure or cylindrical structural, and it is hollow-core construction that it is internal, and its upper end is provided with the first gap, first gap Shape is consistent with the shape of the piston 3, and the right-hand member of the piston 3 is provided with the second gap, is connected with by second gap Connecting rod 4, the front end of connecting rod 4 is chondritic, and its middle-end and rear end constitute sector structure, the first of the upper end of the piston 3 Opening position is connected with piston adjustment axle 5, and the shape of piston adjustment axle 5 is consistent with the shape of first gap, and the piston is adjusted The lower semisection of bearing 5 is in the inside of the piston, the exposed upper end in the piston 3 of its upper semisection.
