Description
Technical field
The utility model relates to a kind of liftable platform.
Background technology
Hoistable platform is a kind of common frame for movement, it is to be mainly used to provide a kind of workbench that can lifting, be convenient to clamping workpiece or machined, its main member-base plate and lifter plate are all generally to adopt the mode of casting to process, after machine-shaping, select again corresponding jacking equipment, current jacking equipment is more, the main scissor lift arrangement that comprises complicated structure, the comparatively simple spiral lift device of the air pressure that cost is higher or hydraulic lift and structure, in spiral lift device, be the most nothing but the simple combination that is provided with externally threaded adjusting rod and nut, but the shortcoming of this screw thread lowering or hoisting gear is also obvious, in actual use procedure, in external applied load, there is vibration, change, material at high temperature need become etc. and can cause frictional force to reduce, in screw thread pair, normal pressure is at a certain pop-off, frictional force is zero, thereby make thread connection loosening, affect working effect.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of screw-type hoistable platform that can loosen.
For addressing the above problem, the utility model provides a kind of hoistable platform, comprise base and be vertically set on the adjusting rod on described base, it is characterized in that, described adjusting rod is provided with external screw thread, described base top is provided with a lifting platform, on described lifting platform, roll and be connected with an adjusting nut coordinating with the external screw thread of described adjusting rod, described adjusting nut comprises that protrusion is arranged on the protuberance of described lifting platform below, on described protuberance, be fixedly connected with a ratchet, on described lifting platform, be hinged with the ratchet coordinating with described ratchet.
As further improvement of the utility model, the lower surface of described lifting platform is also fixedly connected with fixed block, between described fixed block and described ratchet, is connected with spring.
As further improvement of the utility model, on described base plate, be also vertically provided with at least one guide post, described lifting platform passes described guide post and can vertically slide along described guide post.
As further improvement of the utility model, described adjusting nut is connected on described lifting platform by rolling bearing.
As further improvement of the utility model, described guide post is four bars, and the distribution that is square, and described adjusting nut is positioned at the central authorities of described lifting platform.
As further improvement of the utility model, also comprise some rotatable rollers of described base plate lower surface that are arranged on, described base plate lower surface is also provided with a groove, and described roller can completely fold and put in described groove.
The beneficial effects of the utility model are, ratchet and pawl is set, when adjusting nut drives ratchet rotation upwards, drive lifting platform is moved upward, now during the every tooth through on ratchet of ratchet, all can skid off along the outside of this tooth, do not affect the rotation of ratchet; When adjusting nut rotates when downward, to drive ratchet with same direction rotation, now, ratchet can snap onto the root of this tooth through the inner side of a tooth on ratchet, it cannot be rotated, and can prevent that like this adjusting nut is rotated down, play the effect of loosening, stop lifting platform to decline, this loosening device is simple in structure, with low cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the upward view of lifting platform in this Fig. 1;
Wherein: 2-guide post, 4-ratchet, 6-adjusting rod, 8-adjusting nut, 10-ratchet, 12-lifting platform, 14-base, 16-protuberance, 18-spring, 20-fixed block.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As depicted in figs. 1 and 2, the utility model provides a kind of hoistable platform, comprise base 14 and be vertically set on the adjusting rod 6 on base 14, adjusting rod 6 is provided with external screw thread, base 14 tops are provided with a lifting platform 12, on lifting platform 12, roll and are connected with an adjusting nut 8 coordinating with the external screw thread of adjusting rod 6, and adjusting nut 8 comprises that protrusion is arranged on the protuberance 16 of lifting platform 12 belows, on protuberance 16, be fixedly connected with a ratchet 10, on lifting platform 12, be hinged with the ratchet 4 coordinating with ratchet 10.
In the utility model, ratchet 10 and ratchet 4 are set, when adjusting nut 8 drives ratchet 10 rotations upwards, drive lifting platform 12 is moved upward, now during the every tooth through on ratchet 10 of ratchet 4, all can skid off along the outside of this tooth, do not affect the rotation of ratchet 10; When adjusting nut 8 rotation is downward, to drive ratchet 10 with same direction rotation, now, ratchet 4 can snap onto the root of this tooth through the inner side of a tooth on ratchet 10, it cannot be rotated, and can prevent that like this adjusting nut 8 is rotated down, play the effect of loosening, stop lifting platform 12 to decline, this loosening device is simple in structure, with low cost.
As further improvement of the utility model, the lower surface of lifting platform 12 is also fixedly connected with fixed block 20, and 4, fixed block 20 and ratchet are connected with spring 18.
After the tooth of ratchet 4 on ratchet 10 skids off, under the effect of spring 18, be convenient to it and restore to the original state, because if the irreplaceable words of ratchet 4 will depart from ratchet 10, when ratchet 10 reverse rotation, ratchet 4 does not just have the effect of the rotation that holds it back.
As further improvement of the utility model, on base plate, be also vertically provided with at least one guide post 2, lifting platform 12 passes guide post 2 and can vertically slide along guide post 2.
Guide post 2 is set, is convenient to lifting platform 12 and leads when moving up and down.
As further improvement of the utility model, adjusting nut 8 is connected on lifting platform 12 by rolling bearing.
Mode by rolling bearing can realize adjusting nut 8 and be rotatably connected on this lifting platform 12.
As further improvement of the utility model, guide post 2 is four bars, and the distribution that is square, and adjusting nut 8 is positioned at the central authorities of lifting platform 12.
Adopt this structure, can make the balance of lifting platform 12 comparison when lifting.
As further improvement of the utility model, also comprise some rotatable rollers of base plate lower surface that are arranged on, base plate lower surface is also provided with a groove, and roller can completely fold and put in groove.
Roller is set, and being convenient to this hoistable platform can integrated moving, and this roller can fold completely and put in groove, thereby can not affect this hoistable platform, does not lay.
Above-described embodiment is preferably embodiment of the utility model; but embodiment of the present utility model is not limited by the examples; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify and all should be equivalent substitute mode, within being included in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
