The specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of Portable lifting mechanism that the embodiment of the invention provides comprises carriage 1, four carriage legs 2, the first middle part bar 3, the second middle part bar 4, adjust bar 5 and limiting stoppers 6.Link to each other by pin uranium with four carriage legs 2 respectively around the bottom of carriage 1, four carriage legs 2 can rotate around bearing pin in the certain angle scope.Article four, carriage leg 2 middle parts are provided with unthreaded hole, and the first middle part bar 3 two ends are installed in the unthreaded hole at two carriage leg 2 middle parts, can axial-rotation; The second middle part bar 4 two ends are installed in the unthreaded hole at two other carriage leg 2 middle parts, can axial-rotation.The first middle part bar 3 middle parts are provided with unthreaded hole, and the second middle part bar 4 middle parts are provided with tapped bore.One end of adjust bar 5 is provided with screw thread, and the other end is equipped with handle, and adjust bar 5 is established the unthreaded hole that a threaded end passes on the first middle part bar 3 and is threaded with tapped bore on the second middle part bar 4, can axial-rotation, regulate the distance between two pairs of carriage legs 2.Adjust bar 5 can mounting limit device 7 near the place of the first middle part bars 3, and as a kind of form of implementation of the present embodiment, what inhibiting device 7 adopted is circlip for shaft.If inhibiting device 7 is not installed on the adjust bar 5,5 of adjusts bar have limited the ultimate range between two pairs of carriage legs 2, namely only limited the minimum altitude of carriage 1, by adjust bar 5 only with control carriage 1 rising, this moment can the people for closing up two pairs of carriage legs, convenient transportation and storage; If mounting limit device 7 on the adjust bar 5, adjust bar 5 and inhibiting device 7 can be controlled two pairs of ultimate ranges between the carriage leg 2, namely can control the minimum altitude of carriage 1 fully, can be by the height of regulating adjust bar 5 and control carriage 1 rises and descends under the position-limiting action of inhibiting device 7.Limiting stopper 6 lower ends are provided with unthreaded hole, can be enclosed within on the adjust bar 5 sway on adjust bar 5.Sliding block joint between the lower end of the upper end of limiting stopper 6 and carriage 1 is referring to Fig. 3, as a kind of connection mode of the present embodiment, limiting stopper 6 upper ends arrange inserted link, lower end, carriage 1 middle part is provided with unthreaded hole, in the unthreaded hole under the inserted link insertion carriage 1 on the limiting stopper 6, can slide up and down.Impel in the process of carriage 1 rising and decline when the distance between the adjust bar 5 bracket legs 2, slide up and down in the unthreaded hole of the inserted link on the limiting stopper 6 under carriage 1, can prevent that carriage 1 from deflection occuring in lifting process.Certainly, referring to Fig. 4, another kind of connection mode as sliding block joint between limiting stopper 6 of the present invention and the carriage 1, also can inserted link be set in lower end, carriage 1 middle part, limiting stopper 6 upper ends arrange unthreaded hole, in the unthreaded hole on the inserted link insertion limiting stopper 6 under the carriage 1, can slide up and down connection, prevent that carriage 1 from deflection occuring in lifting process.
During use, to certain direction rotation adjust bar 5, adjust bar 5 will drive the second middle part bar 4 to the direction motion near the first middle part bar 3 by screw thread, the distance between the carriage leg 2 be diminished, thereby make carriage 1 do upward movement.When to opposite spin adjust bar 5, under the position-limiting action of circlip for shaft 7, adjust bar 5 will drive the second middle part bar 4 to the direction motion away from the first middle part bar 3 by screw thread, make the distance between the carriage leg 2 become large, thereby make carriage 1 do descending motion.If the mass of object of placing on the carriage 1 is larger, circlip for shaft 7 can be installed, this moment, 5 of adjusts bar limited the ultimate range between two pairs of carriage legs 2, namely only limit the minimum altitude of carriage 1, can automatically drop to minimum altitude at object action of gravitation subiculum pallet 1.If circlip for shaft 7 is not installed, can also the people for closing up two pairs of carriage legs, convenient transportation and storing.In whole use procedure, because the position-limiting action of limiting stopper 6 can make carriage leg 2 drive carriage 1 and deflection not occur, steadily lifting of carriage 1 in the dipping and heaving process.
It should be noted last that, the above specific embodiment is only unrestricted in order to technical scheme of the present invention to be described, although with reference to example the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
