Description
Technical field
The utility model relates to a kind of display, relates in particular to a kind of sway brace device that improves the display of one-piece construction steadiness.
Background technology
As shown in Figure 1, 2, 3, be the applicant's No. 01258819.9 " improved display sway brace " novel patent in first to file, it is to be made of a base 10, footstock 2-, suspended wall 30, connecting rod 40 and a spring 50; Wherein, base 10 and footstock 20 are connected with first axle center 31, second axle center 32, the 3rd axle center 34, the 4th axle center 42 and with cantilever 30, connecting rod 40 respectively and form a sway brace; The two side of this base 10 near posterior lateral margin across being provided with a gear-stopping bar 11; It is the circular arc limit 44 in the center of circle with axis hole 41 that lower end, the two side trailing edge of this connecting rod 40 respectively forms one, and set axis hole 41 apertures, this lower end, connecting rod 40 two side are greater than the 4th axle center 42 diameters of axle that are placed through wherein; The position of this gear-stopping bar 11 is higher than the 4th axle center 42; Whereby, when being failure to actuate, (please consults simultaneously shown in Fig. 2,3) by connecting rod 40, owing to being subjected to the action of gravity of LCD 60, connecting rod 40 is hang, simultaneously since this moment connecting rod 40 the distance on axis hole 41 centers of circle to circular arc limit 44 greater than the distance on the center of circle to the circular arc limit 44 in the 4th axle center 42, so trailing edge set circular arc limit 44 in lower end, connecting rod 40 two side produces the effect that fastens with gear-stopping bar 11, and make cantilever 30 obtain an anchorage force, and then can be installed in LCD 60 on the connecting base 22 of footstock 20 in order to support.Moreover, because set axis hole 41 apertures, lower end, connecting rod 40 two side are greater than the 4th axle center 42 diameters of axle that are placed through wherein, that is axis hole 41 and 42 in the 4th axle center have a movable space, therefore when up being moved, (please consults simultaneously shown in Fig. 4,5) by connecting rod 40, trailing edge set circular arc limit 44 in lower end, connecting rod 40 two side promptly breaks away from the effect that originally fastens mutually with gear-stopping bar 11, this moment can mobile smoothly cantilever 30 and connecting rod 40, and then can adjust the high and low position of LCD 60.
The structure of aforementioned No. 01258819.9 " improved display sway brace " novel patent, though can reach its intended purposes, and provide a kind of structure more to simplify, with the reduction manufacturing cost, and use more convenient display sway brace structure; Yet, because there is no in its structure can be in order to the design of locked configuration, therefore when the elevation angle of LCD 60 adjusts upward than wide-angle, that is screen when becoming horizontal (as shown in Figure 4) up, the weight of LCD 60 can produce just like the same up strength of drawing connecting rod 40, make set circular arc limit of lower end, connecting rod 40 two side trailing edge 44 and gear-stopping bar 11 break away from the effect (as shown in Figure 5) that originally fastens mutually, and make cantilever 30 lose supporting role, and then produce the shortcoming that LCD 60 falls down.Again, because set axis hole 41 apertures, lower end, connecting rod 40 two side are greater than the 4th axle center 42 diameters of axle that are placed through wherein, so axis hole 41 can form a movable gap with 42 in the 4th axle center, consequently influences the integrally-built steadiness of sway brace.

Above structure is identical with the structure of No. 01258819.9 " improved display sway brace " novel patent, and non-be feature of the present utility model place, so no longer further give unnecessary details.The utility model is to reach its creation purpose technological means and structural attitude thereof of using to be:
One end in the 3rd axle center 340 forms the smaller screw rod of a diameter 341, and the boundary that makes screw rod 341 and the 3rd axle center 340 forms the catch arm 342 of a vertical parallax, pad is provided with the big pad 343 of an area on the catch arm 342, and the outer end of screw rod 341 is revolved lock and is provided with a locking pole 344; Again, the utility model comprises that a brake rod 700 (please consults Fig. 6 simultaneously, shown in 7), these brake rod 700 upper ends are provided with an axis hole 710 and can be sheathed on the screw rod 341, the aperture of axis hole 710 is greater than the bar footpath of screw rod 341, make 341 of axis hole 710 and screw rods have a movable clearance space (please consulting shown in Figure 8 simultaneously), and this clearance space equals the movable clearance space in 420 in axis hole 410 and the 4th axle center at least, and the lower end of brake rod 700 is provided with an axis hole 720, the aperture of axis hole 720 is slightly larger than the 4th axle center 420 diameters of axle (please consulting shown in Figure 9 simultaneously), the axis hole 720 of brake rod 700 just can be sheathed on the 4th axle center 420, and moving according to displacement.Whereby, when the 3rd axle center 340 is placing when being located at the two side of footstock 200, cantilever 300 and connecting rod 400, this brake rod 700 is located between pad 343 and the connecting rod 400, and the sidewall clamping closely of footstock 200, cantilever 300 and connecting rod 400 can be located, and brake rod 700 closely can be held between pad 343 and the connecting rod 400 by locking locking pole 344.
When locking pole 344 is in the pine oil state, because axis hole 710,341 of screw rods and axis hole 410,420 in the 4th axle center respectively have a same movable clearance space, therefore brake rod 700 does not have any effect, that is the utility model and No. 01258819.9 " improved display sway brace " novel patent can be adjusted the high and low position of LCD 600 equally easily.When locking pole 344 is in locking state, it is except can be with footstock 200, cantilever 300 and connecting rod 400 tight clamping location, make cantilever 300 lose supporting role when adjusting upward than wide-angle with the elevation angle that prevents LCD 600, and then avoid outside the situation that LCD 600 falls down, and because the upper end of brake rod 700 is positioned between pad 343 and the connecting rod 400 by tight clamping, therefore can make brake rod 700 as fixing shape tractive 420 in the 3rd axle center 340 and the 4th axle center, and can prevent that 410 of the 4th axle center 420 and axis holes are because of having a displaceable clearance space, and cause the sway brace heavy curtain moving, thereby improve the integrally-built steadiness of sway brace.
From the above and embodiment shown in the drawings as can be known, technological means that the utility model used and structure thereof really can reach the purpose of its creation, have practicality and progressive, and really unprecedented, meet novel patent requirement, so file an application in accordance with the law.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
