Abstract
The invention discloses a lifter. The lifter comprises a support, wherein a boss is arranged in the middle of the support; a through hole is formed in the middle of the boss; a rotatable drive screw penetrates in the through hole; and two guiding pins are also symmetrically arranged on the top of the support fixedly. By a threaded high-precision drive function of the drive screw and a guiding function of the guiding pins, a lifting find-adjustment function of the lifter is fulfilled. The lifter has the advantages that the lifter is compact in structure and small in size, and is easy to operate on the premise of high adjustment precision; and the operation reliability is high.
Description
Technical field
The present invention relates to displacement regulation technology field, relate in particular to a kind of lifter.
Background technology
Existing elevation and subsidence regulating device is a lot, but most structure is more complicated, takes up room large, and price is more expensive, in producing cheaply for some, be unsuitable for using, so just wish a kind of cheaply, jacking system that can widespread use.
Summary of the invention
The present invention solves existing technical matters in prior art, thereby a kind of compact conformation, the small and exquisite lifter of the bodily form are provided.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals:
Lifter of the present invention, comprises bearing, and described bearing middle part is provided with a boss, in the middle of described boss, is provided with a through hole, wear a rotatable drive screw, and the top of described bearing is also fixed with symmetrically arranged two guide fingers in described through hole.
Further, between described drive screw and described through hole, be also provided with a lining, described drive screw is rotatable to be located in described lining, described lining is located in described through hole and by a nut locking, and the top of described lining is also provided with a lock screw, described lock screw is used for preventing that described drive screw pine from turning.
Further, the lower end of described drive screw is set with a knurled button, and described knurled button and described drive screw are marked closely screw fastening by one first.
Further, on the sidewall of described boss, wear one for fastening described lining, prevent that second of its deflection from marking closely screw.
Further, the bottom of described bearing is symmetrical two waist-shaped holes that are provided with also, and described bearing is fixed on an external device through described waist-shaped hole by two mounting screws.
Compared with prior art, the invention has the advantages that: by the screw thread high precision transmission of drive screw, coordinate the guiding of guide finger to realize lifting fine adjustment function, have compact conformation, build is small and exquisite, is meeting under the prerequisite of higher degree of regulation, advantage simple to operate, functional reliability is good.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of lifter of the present invention;
Fig. 2 is the exploded view of lifter of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made to more explicit defining.
Consult shown in Fig. 1-2, lifter of the present invention comprises bearing 100, and bearing 100 middle parts are provided with a boss 120, is provided with a through hole in the middle of boss 120, in through hole, be equipped with a rotatable drive screw 30, and the top of bearing 100 is also fixed with symmetrically arranged two guide fingers 20.Outside treats that jacking equipment bottom arranges a tapped bore matching with described screw rod 30 and the pilot hole matching with guide finger 20, with top when jacking equipment coordinates, drive screw 30 is penetrated to top to be treated in the tapped bore in jacking equipment, two guide fingers 20 penetrate top and treat in the pilot hole in jacking equipment, by knob drive screw 30, promote top and treat that jacking equipment rises or declines, and realizes the object of lifting.
In the present embodiment, between drive screw 30 and through hole, be also provided with a lining 70, drive screw 30 is rotatable to be located in lining 70, lining 70 is located in through hole and by nut 60 lockings, and the top of lining 70 is also provided with a lock screw 80, lock screw 80 turns for preventing drive screw 30 pines.Lining 70 can be used the material that hardness is slightly low, and it is on the one hand for lubricated effect, in the friction pair forming, as holding the part that rubs, is also convenient for changing on the other hand after easy to process, the wearing and tearing of lining 70 at lining 70 and drive screw 30.For aspect knob drive screw 30, in the lower end of drive screw 30, be set with a knurled button 40, it is fastening that knurled button 40 and drive screw 30 are marked closely screw 50 by one first, also can be fastening with drive screw 30 by other means.
Preferably, on the sidewall of boss 120, wear one for tight bushing 70, prevent that second of its deflection from marking closely screw 110.The bottom of bearing 100 is symmetrical two waist-shaped holes 130 that are provided with also, and bearing 100 is fixed on an external device through waist-shaped hole 130 by two mounting screws 140.Be used for making lifter to be fixedly connected with external device.The object that two waist shaped holes 130 are set is that the distance of mounting screw 140 is adjustable.Install aspect on the one hand, also reduces on the other hand the accuracy of manufacture of mounting hole with matching.
In use, only need to rotate knurled button 40, by drive screw 30 and top, treat the relative rotation of the tapped bore on jacking equipment, can realize the lift adjustment object of lifter.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
