Embodiment
Referring to figs. 1 to Fig. 3, preferred embodiment of the present utility model provides a kind of screen mount, and for example, for a screen 10 being arranged to a fixture (table), it comprises: a fixture 100, a connecting rod 200, a screen link 201 and a pivot structure 300.
Fixture 100 is in order to grip thing, fixture 100 comprises one first link 110, the first link 110 is that a tinsel bending forms, it generally is the U font and has on 101,102, two side plates 101,102 of two side plates to run through respectively and offer first opening 111 and the axis hole 112 arranged aligning.
A wherein end pivot joint screen link 201 of connecting rod 200, be provided with at least one second link 210 on the other end, screen link 201 interlocking screens 10 and make connecting rod 200 pivot joint screens 10.Preferably comprise two the second links 210 in the present embodiment, each second link 210 is a tinsel, and it runs through the shape that offers second opening 211, the second openings 211 is not circular.
Pivot structure 300 comprises a rotating shaft 310, a helical spring 320 and a sleeve 330.The section of accepting 312 that rotating shaft 310 comprises a holding part 311 and 311 extensions of self-retaining section, the external diameter of holding part 311 is greater than the external diameter of the section of accepting 312, and axis hole 112 is placed in holding part 311.On two ends of rotating shaft 310, the end of self-retaining section 311 and the section of accepting 312 extends formation one rotating shaft connecting end 313 respectively, and the radial section of these two rotating shaft connecting ends 313 is not preferably circular.The radial section shape of rotating shaft connecting end 313 is coincident with the second opening 211, and rotating shaft connecting end 313 penetrates the second opening 211, makes the second link 210 and the rotating shaft 310 can't be along circumferentially relatively rotating.On each rotating shaft connecting end 313, nut 103 of interlocking respectively in the outside of the second link 210, to prevent that the second link 210 is along axially the deviating from of rotating shaft 310, and be fixedly connected on the second link 210 in rotating shaft 310.Preferably between nut 103 and the second link 210, can be folded with a pad 104.
Sleeve 330 is preferably the hollow cylinder of two end openings, its internal diameter is not less than the external diameter of the section of accepting 312, and the rough internal diameter (preferably the external diameter of holding part 311 is slightly larger than the external diameter of sleeve 330, but the utility model is not limited to this) that equals helical spring 320 of its external diameter.A wherein end of sleeve 330 is a sleeve connecting end 331, the radial section of sleeve connecting end 331 is not preferably circular and is coincident with the first opening 111, the first opening 111 is placed on sleeve connecting end 331, makes the first link 110 and the sleeve 330 can't be along circumferentially relatively rotating.Sleeve 330 with respect to rotating shaft 310 rotatably coaxial sleeve be located at the section of accepting 312 and between the inboard and the section of accepting 312 of helical spring 320, helical spring 320 self-retaining sections are extended and are wound around and encircle the outer rim at sleeve 330, make the inboard of the outer surface contact helical spring 320 of sleeve 330.
With reference to figure 4 and Fig. 5, when screen 10 provides a gravity, and make sleeve 330 along helical spring 320 tighten direction with respect to rotating shaft 310 rotation the time, by the stiction between sleeve 330 and helical spring 320 inboards, sleeve 330 just drives helical spring 320 and reverses and helical spring 320 bestowed to a moment of torsion simultaneously along tightening direction, the internal diameter of helical spring 320 dwindles and packing sleeve 330, stop sleeve 330 along tightening direction with respect to rotating shaft 310 rotations, the position of connecting rod 200 is fixed.
When screen 10 is pushed down, sleeve 330 is continued along tightening direction with respect to rotating shaft 310 rotations, stiction reaches maximum and moment of torsion that it is provided is less than the reaction torque that helical spring 320 produces, and helical spring 320 just breaks away from the drive of sleeve 330 and replys no-load condition.Reply no-load condition when helical spring 320, its reaction torque disappears, and sleeve 330 again drives helical spring 320 by stiction and reverses and packing sleeve 330 along tightening direction.When screen 10 is pushed upwardly, sleeve 330 drives helical spring 320 and, against in tightening direction, helical spring 320 being reversed, makes the internal diameter of helical spring 320 enlarge, and the frictional force that helical spring 320 and sleeve are 330 reduces and is easy to promote.
Screen mount of the present utility model reaches with the inboard packing sleeve 330 increase area of contact of helical spring 320 effect that increases damping to increase frictional force, the area of contact of helical spring of the present utility model 320 inboards and sleeve 330 is much larger than the area of contact of helical spring two ends of prior art and pivot device, therefore screen mount of the present utility model, the frictional force that its pivot structure produces is much larger than prior art, therefore can anti-loading also higher.
Certainly; the utility model also can have other various embodiments; in the situation that do not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the utility model claim.
