Abstract
The invention discloses a kind of lifter, comprise bearing, in the middle part of described bearing, be provided with a boss, be provided with a through hole in the middle of described boss, wear a rotatable drive screw in described through hole, and the top of described bearing be also fixed with symmetrically arranged two guide fingers.The present invention is by the screw thread high precision transmission of drive screw, and coordinate the guiding of guide finger to realize lifting fine adjustment function, have compact conformation, build is small and exquisite, under the prerequisite meeting higher degree of regulation, simple to operate, the advantage that functional reliability is good.
Description
Technical field
The present invention relates to displacement regulation technology field, particularly relate to a kind of lifter.
Background technology
Existing elevation and subsidence regulating device is a lot, but most structure is more complicated, and take up room large, price is more expensive, uses for being unsuitable in the production of some low costs, thus just wish a kind of low cost, can the jacking system of widespread use.
Summary of the invention
The present invention mainly solves technical matters existing in prior art, thus the lifter providing a kind of compact conformation, the bodily form small and exquisite.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals:
Lifter of the present invention, comprises bearing, is provided with a boss in the middle part of described bearing, 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 in the middle of described boss.
Further, a lining is also provided with between described drive screw and described through hole, described drive screw is rotatable to be located in described lining, described lining to be 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 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 mark closely screw fastening by one first.
Further, the sidewall of described boss wears one for fastening described lining, prevent it from deflecting second marks closely screw.
Further, the bottom of described bearing is also symmetrical is provided with two waist-shaped holes, 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, under the prerequisite meeting higher degree of regulation, simple to operate, the advantage that 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, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of lifter of the present invention;
Fig. 2 is the exploded view of lifter of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Consult shown in Fig. 1-2, lifter of the present invention comprises bearing 100, is provided with a boss 120 in the middle part of bearing 100, is provided with a through hole in the middle of boss 120, be equipped with a rotatable drive screw 30 in through hole, and the top of bearing 100 is also fixed with symmetrically arranged two guide fingers 20.Outside treats to arrange a tapped bore matched with described screw rod 30 and the pilot hole matched with guide finger 20 bottom jacking equipment, when coordinating until jacking equipment with top, drive screw 30 is penetrated in the tapped bore treated in jacking equipment on top, two guide fingers 20 penetrate in the pilot hole treated in jacking equipment on top, by knob drive screw 30, promote top and treat that jacking equipment rises or declines, realize the object of lifting.
In the present embodiment, a lining 70 is also provided with between drive screw 30 and through hole, drive screw 30 is rotatable to be located in lining 70, lining 70 is worn in through-holes and is locked by a nut 60, and the top of lining 70 is also provided with a lock screw 80, lock screw 80 turns for preventing drive screw 30 pine.Lining 70 can use the material that hardness is slightly low, its effect on the one hand for lubricating, as holding the part that rubs in the friction pair that lining 70 and drive screw 30 forms, on the other hand lining 70 easy to process, wear and tear after be also convenient for changing.In order to aspect knob drive screw 30, be set with a knurled button 40 in the lower end of drive screw 30, it is fastening that knurled button 40 and drive screw 30 mark closely screw 50 by one first, also by other modes and drive screw 30 fastening.
Preferably, the sidewall of boss 120 wears one for tight bushing 70, prevent it from deflecting second marks closely screw 110.The bottom of bearing 100 is also symmetrical is provided with two waist-shaped holes 130, and bearing 100 is fixed on an external device through waist-shaped hole 130 by two mounting screws 140.Be fixedly connected with external device for making lifter.The object arranging two waist shaped holes 130 is that the distance of mounting screw 140 is adjustable.Aspect is installed on the one hand, also reduces the accuracy of manufacture of mounting hole with matching on the other hand.
In use, only need to rotate knurled button 40, treated the relative rotation of the tapped bore on jacking equipment by drive screw 30 and top, the lift adjustment object of lifter can be realized.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
