Description

连杆式升降装置 Lift link means

(1)技术领域本实用新型涉及一种连杆式升降装置,特别是涉及一种将弹性单元设置于连杆中段且使用于液晶显示器的连杆式升降装置。 (1) Technical Field The present invention relates to a link type lifting device, particularly to an apparatus for the lifting rod elastic unit disposed in the middle of the link and used for a liquid crystal display.

(2)背景技术如图1所示,以往液晶显示器的连杆式支撑装置9是于一底架90上设置一支架91,支架91上固定一第一枢接板92。 (2) Background art 1, the conventional link-type liquid crystal display supporting device 9 is provided with a bracket 91 on a chassis 90, a first fixed pivot 92 on the support plate 91. 再借由两枢轴93分别穿套两扭力弹簧94,将两连杆组95的一端96分别枢接于第一枢接板92。 Then by means of two pivots 93, respectively sleeved two torsion spring 94, one end 95 of the two linkage 96 are pivotally connected to the first pivot plate 92. 该两连杆组95的另一端97分别枢接于一第二枢接板98,第二枢接板98再枢接一固定架99,该固定架99供固定一液晶显示器(未图示)。 The other end of the linkage 95 of two 97 are pivotally connected to a second pivot plate 98, the second pivot plate 98 pivoted to a bracket 99 and then, the fixing frame 99 for fixing a liquid crystal display (not shown) .

借由扳转固定架99,可调整液晶显示器的俯仰角度,而借由下压或上抬连杆组95,可调整液晶显示器前、后、上、下位置。 Pull the switch 99 by means of the holder, to adjust the pitch angle of the liquid crystal display, and pressed by means of linkage 95 or elevation, an adjustable liquid crystal display front, rear, upper and lower positions.

参阅图1、2,因为液晶显示器的重量W于连杆组95的作用点97,与支点96(连杆组95的另一端96)间的距离D相当大,也即力臂D相当大,因此W×D所产生的力矩也相当大。 Referring to Figure 1, because the weight W of the liquid crystal display 95 of the set point of a link 97, the distance D and the fulcrum 96 (the other end 95 of linkage 96) between the relatively large, i.e. relatively large moment arm D, Thus W × D torque generated is quite large. 所以用以支撑液晶显示器重量的扭力弹簧94所提供的弹性恢复扭矩M也需相当大,因此扭力弹簧94必须具有较大线径或较多圈数方能足以承受。 The elastic to support the weight of the liquid crystal display provided by the torsion spring 94 restoring torque M also need relatively large, and therefore the torsion spring 94 must have a larger diameter or a larger number of turns in order to withstand. 但大线径且多圈数的扭力弹簧不但增加材料成本,且连杆组末端的空间狭小,致使大线径且多圈数的扭力弹簧组装不易。 However, the torsion spring and the number of large diameter a plurality of turns not only the material cost increases, and the narrow end of the linkage space, resulting in a large number of turns of wire diameter and more difficult to assemble the torsion spring.

而且,扭力弹簧94需穿套枢轴93做为支撑,以防止扭力弹簧扭曲变形致使丧失弹簧功能。 Further, the torsion spring 94 is sleeved required as a support pivot 93, to prevent distortion of the torsion spring causes the loss of spring function. 然而枢轴93穿设扭力弹簧94却造成使用时两构件间的摩擦,轻者产生刺耳异音,重者使得受力仅局限于扭力弹簧的部份区段,无法均布于整体长度,造成该区段的变形超出弹性变形范围而破坏。 However, the pivot 93 through the torsion spring 94 is provided between the two has caused the friction member is used, the light generating abnormal sound harsh, severe stress is limited to that portion of the torsion spring sections, the overall length can not be uniformly distributed, resulting in the deformation zone exceeds the range of elastic deformation and damage.

此外,支撑用的枢轴不但造成组装的不便,也徒增材料成本。 Further, with the pivot support assembly not only cause inconvenience, but also inviting cost material.

另外,如图14、15所示,也可同时省略图3中的第一、二柱体44、54和第一、二片体43、53,另于两第一杆体41中段较上方处及两第二杆体51中段较下方处各具一勾挂孔58。 Further, as shown in FIG. 14 and 15, it can also be omitted in FIG first and second posts 44 and 54 and the first and second sheet 43, 53 in FIG. 3, the other two in the middle than the first rod 41 and above the two middle second rod member 51 each having a hooking hole 58 than at the bottom. 将一弹性单元49k的自由端48分别勾固于第一、二杆体同侧的勾挂孔58;再将另一相同的弹性单元49k的自由端48分别勾固于第一、二杆体另一侧的勾挂孔58。 A free end of the elastic unit 49k of the hook 48 are fixed to the first, two hooking holes 58 of the body of the same side; the same and then the other free end 49k of the elastic unit 48 are fixed to the first hook, the other two bodies hooking hole 58 side.

此外,如图16、17、18所示,本实用新型除省略图3中的第一、二柱体44、54和第一、二片体43、53外,也可将扭力弹簧或压缩螺旋弹簧更换为拉伸螺旋弹簧弹性单元49n,并使拉伸螺旋弹簧弹性单元49n的一端勾固于第一肋42的下缘,并使另一端勾固于第二肋52的上缘。 Further, as shown in FIG. 16, 17, in addition to the present invention are omitted in FIG. 3 the first and second posts 44, 54 and first and second outer sheet 43, 53 can also be a torsion spring or a compression coil replace the spring tension coil spring elastic unit 49n, and an end of the tension coil spring elastic unit 49n is fixed to the lower edge of the hook 42 of the first rib, the hook and the other end fixed to the edge of the second rib 52. 或更进一步第一肋42的宽度缩减成位于第一杆体中段较下方处的一横棒(未图示),并使第二肋52的宽度缩减成位于第二杆体中段较上方处的一横棒(未图示),供拉伸螺旋弹簧弹性单元49n两端的勾固。 Or the width of the first rib 42 is further reduced to the first rod located in a middle section thereof than at the lower horizontal rod (not shown), and the width of the second rib 52 is reduced to a second rod positioned at the upper middle section thereof than a cross- bar (not shown) for fixing hook stretching across the coil spring elastic unit 49n.

在图16、17、18的实施例中,当位于较高的第一位置时,第一、二连杆单元4、5固定拉伸螺旋弹簧弹性单元49n的两端矩离H,较位于较低的第二位置时第一、二连杆单元4、5固定拉伸螺旋弹簧弹性单元49n的两端矩离h小。 In the embodiment of FIG. 16, 17, when a first position is located higher, the first and second link units 4 and 5 is fixed at both ends of the tension coil spring moment of the elastic unit 49n from H, than in the less a second lower position when the first and second link units 4 and 5 is fixed at both ends of the tension coil spring torque from the elastic unit 49n h small. 因此当施力下压连杆式升降装置100时,必须克服弹性单元49n拉伸变形的弹性恢复力,所幸此时有液晶显示屏物件重量W之助,所以仍可轻易下压。 Thus, when the pressing force-link lifting device 100, must overcome the elastic deformation of the elastic unit 49n tensile restoring force, but fortunately this case are liquid crystal display of the object W by weight promoter, it can still be easily pressed. 相反地,当欲将连杆式升降装置100自第二位置上抬至第一位置时,弹性单元49n的弹性恢复力可帮助克服液晶显示屏物件向下的重量W,所以可省力地上抬。 Conversely, when wishing to lift the link 100 from the second position raised above the first position, the elastic unit 49n elastic restoring force that helps overcome the downward weight of the LCD object W, so that effort may be lifted up.

另外,第一枢接单元3可直接固定于另一物件的根撑面,而不需借助衔接座2和底座1。 Further, the first pivoting means 3 may be directly fixed to the supporting surface of the other root object, without need to rely adapter base 2 and the base 1. 或第一枢接单元3固定于衔接座2后就直接固定于另一物件的根撑面,而不需借助底座1。 Or the first pivoting means 3 is fixed to the adapter 2 is directly fixed to the other after the root object support base surface, the base 1 without the need to rely on.

如图2所示,本实用新型因将弹性单元49设置于第一、二连杆单元4、5的中段,而非设于其一端40、55,因此弹性单元49的弹性恢复力f的作用点与根点(第一、二杆体的一端通孔)40、55间尚存有一较大的力臂d,两者乘积所产生的力矩(f×d)和以往设于连杆95一端96的扭力弹簧94所提供的扭矩M,若要根撑相同的液晶显示器物件的重量W,本实用新型弹性单元49所需提供的弹性恢复力f可较小,也即本实用新型弹性单元49的线径或圈数可较小,因此可轻易组装且降低材料成本。 2, the present invention due to the elastic unit 49 is provided in the middle of the first and second link units 4 and 5, rather than 40, 55 provided at one end thereof, the elastic restoring action of the resilient means 49 force f point and the base point (the first, two end of the through-hole member) 40, 55 between a large arm surviving d, torque (f × d) and the product of the two produced 95 conventionally provided at one end of the connecting rod 96 the torque M torsion spring 94 provided, to hold the root of the same weight of a liquid crystal display object W, the elastic unit 49 according to the present invention is required to provide an elastic restoring force f can be made small, i.e. the present invention the elastic unit 49 diameter or number of turns may be small, and therefore can be easily assembled and reduced material costs.

又因本实用新型的弹性单元49较小且不需以往枢轴93,同时弹性单元49是设置于空间较大的连杆单元4、5中段而非末端,因此组装容易,从而降低组装及材料成本,且无摩擦异音。 The present invention because the elastic unit 49 is small and does not require a conventional pivot 93, while the elastic unit 49 is disposed in the middle instead of 4,5-terminus link unit larger space, and therefore easy to assemble, thereby reducing material and assembly cost, and no abnormal noise friction.

另外,因无以往枢轴93的摩擦阻挡,使弹性单元49变形的内应力可均布于弹性单元49整体,不致局部破坏。 Further, because no conventional friction blocking of the pivot 93, so that deformation of the elastic unit 49 may be uniformly distributed in the internal stress of the elastic unit 49 overall, without local destruction.

此外,连杆单元4、5中段的空间较大,所以容许将固定弹性单元49的构造略进行变化,供选择采用扭力、压缩螺旋、或拉伸螺旋等各种弹性单元,设计自由度大。 In addition, the space in the middle of the link units 4 and 5 is large, the configuration allowing the elastic unit fixing 49 slightly changes, alternative uses torsion compression coil, tension coil or other resilient means, design freedom.

当然,本技术领域中的普通技术人员应当认识到,以上的实施例仅是用来说明本实用新型,而并非用作为对本实用新型的限定,只要在本实用新型的实质精神范围内,对以上所述实施例的变化、变型都将落在本实用新型权利要求书的范围内。 Of course, those skilled in the art should appreciate that the above embodiments are merely to illustrate the present invention, and are not used as of the new defining practical, as long as the present invention the true spirit scope of the above the range of variation of the described embodiment, modifications of the present invention will fall within the claims.
