Embodiment
Consult shown in Fig. 1,2, the utility model essential structure comprises that adjutage 20, that a master arm 10, is articulated in master arm 10 rear ends is articulated in master arm 10 front ends and can be articulated in adjutage 20 rear ends for the display holder 30, that display 50 fixedly hangs and whole sway brace can be fixed on sway brace holder 40 on the wall 80 (or other fixed objects); Wherein, 20 of master arm 10 and adjutages, master arm 10 and 30 of display holders, adjutage 20 and 40 of sway brace holders are respectively equipped with a Z-axis 60, but make 40 of master arms 10, adjutage 20, display holder 30, sway brace holder form the joint of a left-right rotation with Z-axis 60 respectively, so make display 50 can be arbitrarily about the angle of its use of adjustment.
Above-mentioned master arm 10 also includes the sleeve pipe 15, that spring 14, that a preceding connecting base 11 that is articulated in its front and back end and back connecting base 12, one be sheathed on connecting rod 13 back segments with the isometric connecting rod 13, of master arm 10 is sheathed on connecting rod 13 leading portions and covers the dust cap 16 that places on the main brace arm 10; Wherein, first sway brace 10 is the body of rod that a cross section generally is the Qian font, is provided with for connecting rod 13, and the front and back ends of master arm 10 is articulated on preceding connecting base 11, the back connecting base 12, shown in Fig. 2, Fig. 2 A with first horizontal shaft tip 71, the second horizontal shaft tip 72 respectively.The front and back ends of connecting rod 13 is articulated on preceding connecting base 11, the back connecting base 12 with the 3rd horizontal shaft tip the 73, the 4th horizontal shaft tip 74 respectively, and make connecting rod 13 and master arm 10 form parallel shape, make master arm 10 and connecting rod 13 form the joint that to rotate up and down according to first horizontal shaft tip 71, second horizontal shaft tip the 72, the 3rd horizontal shaft tip the 73, the 4th horizontal shaft tip 74 respectively, shown in Fig. 3 A, Fig. 4 A.Have, the rear end of connecting rod 13 is provided with a stop block 131 again, and stop block 131 proper ammunition feed springs 14 rear ends are replaced, and the front end of connecting rod 13 is provided with one section screw thread 132, and is installed with a nut 133, and nut 133 is just replaced for sleeve pipe 15 front ends.
From the above mentioned, the utility model essential structure is general basic identical with existing display sway brace, so no longer further give unnecessary details; Of the present utility model being characterised in that,
The two side of above-mentioned back connecting base 12 is respectively equipped with a circular-arc gear wall edge 121, this stop block 131 is into moving type and is sheathed on connecting rod 13 rear ends, and being respectively equipped with a free gear 134 in the both sides of this stop block 131, this free gear 134 is just replaced and is engaged in gear wall edge 121.
By above-mentioned structure design, when moving up and down master arm 10, free gear 134 can be replaced to be engaged on the gear wall edge 121 and roll.Yet, because the 4th horizontal shaft tip 74 that is articulated in connecting rod 13 rear ends to the every bit of circular-arc gear wall edge 121 all becomes not equidistant, that is distance more up is more little, and distance more down is big more, like this, when display 50 is upwards drawn high, when making master arm 10 be vertical angle to spend (as shown in Figure 3), free gear 132 can be along gear wall edge 121 displacement that scrolls up, and stop block 131 will be retired backward at this moment; And fallen when display 50 pulls down, when making master arm 10 be sagging angle (as shown in Figure 4), free gear 132 will be along gear wall edge 121 downward barrel shifts, this moment, stop block 131 will be forced to past anterior displacement and extrusion spring 14, impel spring 14 to produce bigger bounce-back tension force, providing a bigger anchorage force to master arm 10, and then can prevent that master arm 10 from down slipping out with support displays 50.
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.
In sum, the utility model is on structural design, use practicality and cost benefit, it is required to meet industry development fully, and the structure that is disclosed also is to have unprecedented innovation structure, have novelty, creativeness, practicality, meet novel patented claim important document, so mention application in accordance with the law.
