Abstract
The invention discloses an elastic friction conical display support frame. According to the display screen support frame, main weight components of the display screen are basically balanced and resisted by spring force and/or friction force, so that the screen tilts and rotates to acquire a viewing angle required by an operator, however, the friction force generated by compression between a relatively movable piece and a stationary piece of the support frame in the prior art is realized by compressing a plurality of elastic pads through high force, the defect is that the diameter dimension and thickness of the elastic pads are correspondingly increased a lot when the screen is heavy and high friction force is required, and the thin weight requirement on the whole machine cannot be met. A shaft lever which is small in size and has the same small taper angle is matched with a taper sleeve, only a small elastic pad is required to be arranged on the shaft lever, so small axial pressure is applied, and high circumferential force can be generated between the taper sleeve and the conical rod; and moreover, enough required friction force can be obtained even if between the movable piece and the stationary piece of the support frame which is respectively connected with the taper sleeve and the shaft lever.
Description
Technical field
The invention discloses the tapered display device of a kind of elastic-friction and (mainly refer to tyrode crystal display screen computer all-in-one machine and independent liquid crystal display panel; Below all be called for short display screen) use supporting frame, need to be specifically related to the display screen supporting frame of frictional force (can be aided with spring force) balance, the main weight component of opposing display device.
Background technique
Display screen is to support and adjust the visual angle by the supporting frame that is contained on its back side on the table, so supporting frame is the inseparable combination of display screen.The inner mechanism of supporting frame want can realize when tilt and or can both hold during in each position, visual angle during moving display screen motionless, also be supporting frame need balance, opposing firmly display device because of the anti-change power of position or its weight component generation of angle variation.
For realizing above-mentioned functions; Usually the weight component that adopts spring force and/or frictional force to come balance, opposing display screen to cause on the support frame structure; But in the existing technology on the supporting frame relative moving part and not between the moving part generation of this frictional force nearly all realize with moving part not by adopting a plurality of resilient pads of big force compresses to compress moving part; Its defective be diameter dimension, the thickness of its resilient pad when needing big frictional force corresponding can increase a lot; Cause the local obviously profile of protuberance, this is unallowed under many circumstances., (and axial dimension requires looser) all the more so when particularly at present the display screen complete machine more and more trends towards frivolous demand, its defective is obvious, to that ultra-thin requirement arranged or even fatal.
Summary of the invention
In order to overcome the defective that above-mentioned existing technology exists; The object of the invention is when complete machine has restriction to the diameter dimension of supporting frame friction mechanism part, provides a kind of diameter dimension the very little display screen supporting frame that but can substitute major diameter, thick resilient pad generation frictional force at moving part and the elastic-friction wimble structure that does not produce big frictional force between the moving part.
The present invention adopts following technical proposals to realize:
A kind of elastic-friction awl phenotype shows the device supporting frame, comprising: axostylus axostyle is spun on the locking nut on the axostylus axostyle and is sleeved on the resilient pad that the nut that is locked on the axostylus axostyle compresses; The not moving part and the moving part that connect display screen and base respectively; It is characterized in that: described axostylus axostyle part shaft is the awl bar that tapering is arranged, and the tapered sleeve that contains identical taper angle hole is sleeved on this awl bar, and the resilient pad that is contained on the axostylus axostyle by the locking nut wedging ring on the axostylus axostyle flexibly is pressed on tapered sleeve on the awl bar; Described moving part or moving part is not reciprocal respectively selects one and be connected mutually with tapered sleeve and axostylus axostyle.
The present invention has made full use of the principle that just can produce the huge circumferential frictional force of amplifying much times when the friction cone of small angle cone angle is secondary only to need very little axial pressing force; Can adopt very minor diameter and very the resilient pad of minimal thickness apply very little axial pressing force and just can bring the very big frictional force of friction cone idol part; And that the friction cone size can be done is very little, can satisfy complete machine that frivolous requirement the is arranged needs to supporting frame.

1. axostylus axostyles among the figure, 2. tapered sleeve, 3. resilient pad, 4. locking nut, 5. not moving part, 6. moving part, 7. base, 8. display screen.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with accompanying drawing and concrete preferred embodiment the present invention is described further.
Referring to accompanying drawing, this preferred embodiment---a kind of elastic-friction awl phenotype shows the device supporting frame.One section shaft on the axostylus axostyle is processed the awl bar that each diameter is not less than thread section diameter (can make full use of the strength of materials of axostylus axostyle like this), very little tapering, and (tapering amplifies the multiple of power as required and sets; Suggestion with Morse's taper or littler why); Be sleeved on the tapered sleeve of boring the identical taper angle of bar with being provided with that to form friction cone idol part on the awl bar secondary, be contained in the resilient pad on the non-tapered section of axostylus axostyle and then tapered sleeve flexibly is pressed on the awl bar by the locking nut wedging ring of axostylus axostyle on it; Tapered sleeve and axostylus axostyle then respectively with supporting frame on relative moving part or not moving part (both should respectively select reciprocal in the lump) be connected; Because common supporting frame moving part and not moving part usually directly connecting firmly display screen and base respectively; So only need be being connected of axostylus axostyle, tapered sleeve and moving part and moving part not and circumferentially be connected and not necessarily will leave no choice but be connected like welding or riveting; So that simplified structure and dismounting, wherein circumferentially be connected and can both be adopted simple known technologies such as non-circular shaft and hole be adaptive.Because required axial force is very little; So the resilient pad diameter can be very little, very thin thickness and quantity also can be less, axial pressure is regulated in their decapacitation can also play automatic compensation because of the secondary frequent axially minimizing of the impacting force that produces of relatively small amount negative displacement of wearing and tearing back of rotating of friction cone so that the circumferential frictional force of control friction cone is outer.The present invention just improves the mechanism that produces frictional force in the supporting frame, obviously then by due other associated part of routine, need not do obvious or big change on it as being merely common supporting frame.
More than show and described basic principle of the present invention, major character and advantage of the present invention.The technician of the industry should know; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, obviously the present invention can have various changes and modifications, and these variations and improvement all fall in the scope of requirement protection of the present invention.The scope that the present invention requires to protect is defined by appending claims and equivalent thereof.
