Cam link mechanism 360 at least comprises rotating disk 362 and connecting rod 361, one end of connecting rod 361 is connected with rotating disk 362, the other end is connected with spring assembly link plate 330, connecting rod is provided with ledge structure 361A, simultaneously, cam link mechanism 360 is also provided with the adjusting knob 365 for rotating rotating disk 362, by operation adjusting knob 365, rotating disk 362 is rotated, the connecting rod 361 be connected with rotating disk 362 is driven together to rotate, due to the other end linking springs assembly link plate 330 of connecting rod 361, the rotation of connecting rod 361 can drive the motion of spring assembly link plate 330.Rotating disk 362 is also provided with top rotary table 362A and lower rotary table 362B, the centre of top rotary table 362A and lower rotary table 362B is equipped with mesopore 363, wherein, top rotary table 362A is provided with a breach 362C, cam link mechanism 360 is also provided with locking element 364, the mesopore 363 of lower rotary table 362B is corresponding with adjusting knob 365 to be installed, the mesopore 363 of top rotary table 362A is corresponding with locking element 364 to be installed, connecting rod 361 is between lower rotary table 362B and top rotary table 362A, with top rotary table 362A connection, when the lower rotary table 362B that adjusting knob 365 is housed is corresponding with the top rotary table 362A that locking element 364 is housed install time, locking element 364 can be connected with adjusting knob 365, lower rotary table 362B and top rotary table 362A is connected and fixed and becomes parts.
Spring assembly link plate 330 is provided with some grabs 332 for connecting extension spring 340, arm-tie 350 is also provided with some draw rings 351 for connecting extension spring 340, position, the quantity of grab 332 are mutually corresponding with draw ring 351, connect the both sides of some extension springs 340 respectively, make extension spring 340 be in tensioning state, choose in the present embodiment extension spring 340, grab 332, draw ring 351 quantity be respectively 5.Meanwhile, arm-tie 350 is also provided with some drag hooks 352 for connecting tensioner 391, and tensioner 391 pairs of bases 10 provide uncontrollable constant tension active force, the quantity choosing drag hook 352 in the present embodiment is 3, wherein, tensioner 391 can be wire, is fixed on slider assembly 3.
In the extension spring device busy for base tensioning adjustment that the utility model provides, by the adjusting knob 365 on rotating cam linkage mechanism 360, rotating disk 362 can be made to produce rotate, because rotating disk 362 is connected with connecting rod 361, the rotation of rotating disk 362 can together be moved by drivening rod 361, simultaneously, the other end linking springs assembly link plate 330 of connecting rod 361, spring assembly link plate 330 can slide along chute 371, the motion of connecting rod 361 continues to drive spring assembly link plate 330 together to move, the circular movement of rotating disk 362 is converted to the straight line motion of spring assembly link plate 330, because spring assembly link plate 330 is connected with fixing extension spring 340, the motion of spring assembly link plate 330 makes extension spring 340 discharge tension force, thus the tension force realizing extension spring device presents the trend of changing from small to big.On the contrary, when tension force reaches maximum, counterrotating adjusting knob 365, extension spring device can be made to present trend from large to small, due to the structural feature of wedging forces pin 381, extension spring is put and forms three kinds of tension force size gears at the volley, the working state of its extension spring device is as follows:
As shown in Figure 4, when support arm 334 on spring assembly link plate 330 is positioned at chute 371 upper end, the tension force of extension spring 340 is minimum, extension spring 340 tension force is in minimum shelves, spring assembly link plate 330 and cam link 361 mechanism 360 are all in initial position, stage clip 382 is in compressive state, and wedging forces pin 381 is in non-working state.
As shown in Figure 5, when support arm 334 is positioned at slip neutral position, wedging forces pin 381 and the spacing hole 311 on base 10 are placed in the middle to the tension force of extension spring time corresponding 340, and extension spring 340 tension force mediates shelves.Lower surface due to wedging forces pin 381 is inclined-plane, when tension force changes from small to big, the minimum point of wedging forces pin 381 lower end surface first contacts the spacing hole 311 on base 10, because lower end surface is in uprising variation tendency by low, wedging forces pin 381 is skidded off from spacing hole 311 when moving, when tension force from large to small time, the peak of wedging forces pin 381 lower end surface first contacts the spacing hole 311 on base 10, because lower end surface is in the trend by high step-down, wedging forces pin 381 can not be skidded off when moving from spacing hole 311, spring assembly link plate 330 and positioning plate 320 can not carry out relative movement with base 10, form limit effect, extension spring device is mediated gear, if make extension spring device get back to original state, by push rod instrument, the wedging forces pin 381 in spacing hole 311 need be ejected, stage clip 382 is in compressive state again, spring assembly link plate 330 can be made to get back to initial position.
As shown in Figure 6, when support arm 334 on spring assembly link plate 330 is positioned at chute 371 lower end, ledge structure 361A on connecting rod 361 is corresponding with the breach 362C on top rotary table 362A, the tension force of extension spring 340 is maximum, extension spring 340 tension force is in maximum, spring assembly link plate 330 and cam link 361 mechanism 360 are all in final position, and stage clip 382 is in compressive state, and wedging forces pin 381 is in non-working state.
In sum, a kind of extension spring device regulated for tensioning that the utility model provides, for the clamping system of support device in display device, there is provided on the basis of safe and reliable tension force in realization, can also the size of tension adjusting, to adapt to the support requirement of different display device, have that structure is simple, simple operation, safe and reliable feature, tension force gear switch can be realized by operation rotary knob, thus regulate or change the size of tension force, make support device have good reliability, be user-friendly to.
Above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to mode of execution of the present utility model.For those of ordinary skill in the field, other multi-form change or variations can also be made on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
