Accompanying drawing explanation
Fig. 1 is structural representation axonometric drawing of the present invention.
Embodiment
By specific embodiment the present invention is described further below in conjunction with accompanying drawing Fig. 1 and illustrates; but not in order to limit the present invention; all within the present invention's spirit and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
As shown in Figure 1, a kind of display device lifting support frame, comprise: the nut part 2 that at least one pair of screws mutually and screw rod part 1(are for reducing costs, this example preferably a pair) (selection of pitch and lubrication should at least when nut part 2 can be able to rotate by described screw rod part 1 when being subject to axial force, for this reason, usual pitch wants large, make described nut part 2 and the mutual not self-locking of described screw rod part 1, certainly, pitch increases and also requires appropriateness, in order to avoid drive described screw rod part 1 rotational velocity is too soon or too slow and cause lifting feel bad when described nut part 2 moves up and down), also comprise: this example of lifters 3(is sheet metal part, be mainly used in accommodation to be connected described nut part 2, another also for directly connecting display screen, or for be more convenient for display screen adjustment pitching and or rotate needed for visual angle, indirectly display screen can be connected by described screen tilt hinge mechanism, this hinge structure and use are the modal known technology of the industry, therefore accompanying drawing does not draw), also comprise: this example of frame member 4(adopts sheet metal part punching press to be bent into the box-like of a upright opening, the left and right sides in its inner face forms the up and down guiding shape sliding groove structure suitable with described lifters 3, for and be convenient to described lifters 3 can slide up and down but can not rotate (such as described lifters 3 correspondence arrange the groove suitable with described frame member 4 or protruding realizes moving up and down each other while limit again the rotation of described lifters 3, but in accompanying drawing this chute class formation because separately having loaded same only lifting guiding can not slide track component 7 described in following two groups of turning effort and outstandingly in the accompanying drawings to express), described screw rod part 1 two ends are supported on described frame member about 4 position respectively pivotally, wherein pivot support method can adopt bearing class as centripetal or thrust or centripetal thrust force structure rolling bearing, certainly, sliding bearing also can, but frictional force is larger, these structure technologies and installation are obviously known technology), this example is for simplified structure and reduce costs, and preferred described screw rod part 1 liang of top head shaft core position is provided with local dent, and described frame member 4 corresponding part also forms local dent, and a coated steel ball 8 realizes the pivot support of described screw rod part 1 jointly.
Also comprise: spline unit 5, be arranged on described frame member 4, manual transfer can press screw rod part 1 described in tactile or screens thus make its spline, this is because should be motionless after screen lifting puts in place, and shield gravity and always attempt to be declined by described nut part 2 to order about described screw rod part 1 and rotate, therefore need by press tactile described screw rod 1 to make it no longer rotate because of the frictional force rotation voluntarily that (or by adaptive retaining structure coordinating as latch and hole slot) carrys out screw rod part 1 as described in backstop of described spline unit 5, thus make the maintenance of lifters 3 lifting position motionless between the two, and obviously, the pressure only need throwing off described spline unit 5 when needing screw rod part 1 to rotate is touched or screens, as for the structure of described spline unit 5 realizing these functions, obviously very simple, known technology is optional too much, this example for the sake of simplicity, adopt manual swing arm 5.3 around axle 5.1 rotation grazing rub screw rod part 1 described in described screw rod part 1(preferably directly does bigger in this local, position diameter maybe can be connected a little greatly dish like members of a diameter pressed to touch to be more convenient for wipe spline) carry out spline, the described axle 5.1 of described swing arm 5.3 and unitary rotation adopts one group of conventional resilient pad 5.2(of the industry to be sleeved on described axle 5.1) mutually compress with the partial bores face axial elasticity of described frame member 4 and (be shaped with screw thread at the other end of described axle 5.1, with nut check) produce frictional force and ensure that described swing arm 5.3 position after manual rotation can be relatively stable, certainly spline unit 5 also can open a little groove or punching in the week edge on described screw rod part 1 as mentioned above, and on support, settle the groove of corresponding setting on the adaptive described screw rod part 1 of manual displaceable latch like members or hole (certainly also can exchange structure conversely) to realize spline, these structures obviously realize also very simple, known technology has much can be selected, therefore do not repeat, and this example does not adopt yet.
Obviously, be more stably supporting display screen, also can increase the base 6 of tabular, described base 6 is connected with described frame member 4, and this routine described base 6 is the conventional structure of the industry, and connects described frame member 4 with screw, further, frame member 4 as described in adjusting as being more convenient for relatively as described in the inclination angle of base 6, also can increase Tilt hinge again, one portion is connected with described base 6, one is connected with described support, these are the very common known technology of the industry, therefore do not repeat, and accompanying drawing is not drawn yet
Further, for making the lifting of lifters 3 described above in described frame member 4 more smooth, also in described frame member 4, at least one slide track component 7 that is connected can be installed, the described slide track component 7 passing through to be connected to make lifters 3 more smoothly relatively described frame member 4 is elevated, this known technology very passed through for the industry, therefore do not repeat, this example is for improving for the purpose of anti-torsion and support stiffness, described slide track component 7 adopts two groups, but also therefore, the adapter structure that can not rotate can only be elevated both rising of arranging with described lifters 3 in obvious described frame member 4 limits also just no longer to need, and be instead of by described slide track component 7, it is worth mentioning that, change into if above-mentioned and adopt discrete the above screw rod part 1 of two couples and described nut part 2, described lifters 3 has been limited rotation because being connected two discrete described nut parts 2 simultaneously, therefore no longer including of obviously becoming of the dependency structure that can only be elevated the rotary spacing of described lifters 3 in described frame member 4 is necessary, certainly now described slide track component just more need not yet, obvious cost may be slightly higher, but this example adopts is the structure of a described slide track component 7.
For the purpose of rapid operation, also comprise at least one spring assembly, it functionally connects described lifters 3 and described frame member 4 respectively, produces opposing, balances the spring force of described display screen gravity when described lifters 3 is elevated; The constant force spring that suggestion adopts the industry the most frequently used, this makes equilibrant can be more constant on whole lifting travel, and it installs the known technology connecting and pass through very much for the industry, therefore does not repeat, certain extension spring 8 grade also can, just elastic force changes greatly with stroke, fortunately because of cause that screw pair is not too responsive to lifting force, operating handle is just slightly poorer, but the life-span is long, price is low, therefore this example adopts.
During concrete use, the described spline unit 5 of release that only need be shifted, to the spline of described screw rod part 1, then drags display screen lifting to desired location by screw rod part 1 described in described spline unit 5 spline locking.When overweight screen etc. is large, when heavily screen hangs up, in case of as described in the fortuitous event such as spring breakage occur time, because of the speedup performance of screw pair, the reasons such as its mechanical efficiency is little, screen gravity falls together with described nut part 2 thus orders about described screw rod part 1 and accelerates to rotate, but increase with the rotating speed of described screw rod part 1, because the frictional resistance moment at the damping oil in screw thread and two ends etc. can nonlinearly sharply increase, thus make the rotating speed of described screw rod part 1 increase slow and just seldom add after being increased to certain speed, therefore, screen rate of descent can not be accelerated too fast so that breaks and or cause personal injury.Again when the screen as Different Weight hangs over this same supporting frame, because of by described spline unit 5 spline and screw pair to the immunity of weight, the screen of multiple weight specification can be supported, save the exploitation of multi items supporting frame, manufacturing expense, also save the time simultaneously.
More than show and describe basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
