The qualifications that can be implemented are not technically meaningful. Any modification of the structure, change of the proportional relationship or adjustment of the size should not fall under the influence of the creation and the purpose of the creation. Within the scope of the technical content disclosed in this creation.

Referring to Fig. 2A, there is shown a schematic view of an embodiment of the lift structure of the present invention. As shown in the figure, the lifting structure 200 with the guiding rod is suitable for supporting the display device (not shown). The lifting structure 200 with the guiding rod mainly comprises a supporting frame 1 and a first sliding rail module. 2. A pulley 3, two guide rods 4, two constant force springs 5, and a base 6.

The support frame 1 includes a main board 11 and two side plates 12 respectively bent from the two sides of the main board 11 for being disposed on a base 6. The base 6 is provided in a manner of omitting the outer casing, and includes a chassis 61 and at least one hinge 62 disposed on the chassis 61 for the support frame 1 to be pivoted on the hinge 62 and pivotable relative to the chassis 61. The lifting structure 200 with the guiding rod can be placed on a working surface (such as a table top or a ground) through the base 6, but the creation is Not limited to this, for example, the working surface can also be a wall surface. In addition, the support frame 1 further includes a reinforcing member 7 for reinforcing the structural strength of the support frame 1.

The first slide rail module 2 is disposed on the main board 11 of the support frame 1. As shown in FIG. 2B, the first slide rail module 2 includes a first outer rail 21, a first inner rail 22 and a first ball member 23. The first outer rail 21 has a first outer rail bottom plate 211 and a first outer rail side plate 212 bent from both sides of the first outer rail bottom plate 211 to form a first sliding slot 213 having a first opening 213a. The first inner rail 22 is slidably disposed in the first sliding slot 213 and has a first inner rail bottom plate 221 and a first inner rail side plate 222 extending from both sides of the first inner rail bottom plate 221 . The first ball member 23 is disposed between the first inner rail 22 and the first outer rail 21, and has a first lining 231 and a plurality of first balls 232 mounted on the first lining 231. The ball 232 slidably contacts the first inner rail side plate 222 and the first outer rail side plate 212, but the creation is not limited thereto. For example, the first rail module 2 may also be non-ball slippery. The rail has no first ball member, and corresponding curved slides are respectively disposed in the first inner rail and the first outer rail, so that the first inner rail and the first outer rail can slide relative to each other along the corresponding slide rail.

The pulley 3 is fixed on the first inner rail 22, and includes a joint plate 31 and a hinge 32 connecting the joint plate 31 and the pulley 3. The display is fixed on the joint plate 31, and the joint plate 31 can be mounted thereon. Pivoting relative to the trolley 3.

The two guide rods 4 are respectively disposed on the two sides of the pulley 3, and have a first end 41 and an opposite second end 42. Each of the first ends 41 is fixed to the trolley 3, and the first slide rail module 2 is clamped. Provided between the guide rods 4, the second end 42 has an ejector member 421.

The two fixed-force springs 5 are respectively fixed on the support frame 1 at one end, and the other end is engaged with the push-up member 421 at the second end 42 of the guide rod 4. Further, the constant-force spring 5 is a scroll spring, A cylindrical portion that is spiraled around a fixed end and a movable end that is fixed to the support frame 1 and that is coupled to the ejector member 421. When the guide rod 4 drives the ejector member 421, the ejector member 421 pushes the cylindrical portion to deform the vortex spring.

In this embodiment, the first slide rail module 2 is fixed on the support frame 1 in such a manner that the first opening 213a faces the main board 11 of the support frame 1 , whereby the trolley 3 follows the first When the inner rail 22 slides, the guide rod 4 can be driven to push the fixed force spring 5 with the ejector member 4, so that the object such as the trolley 3 and the display can be at a lowest position (as shown in FIG. 2C) and The highest position (as shown in Figure 2D) stops. The number of the constant force springs 5 is not limited to two, and may be one or three, as long as the pulling force is substantially equivalent to the object such as the trolley 3 and the display, and the stop effect can be produced. In addition, the first sliding rail module 2 can also be fixed to the supporting frame by the first opening 213a facing away from the main board 11 of the supporting frame 1 (that is, the first sliding rail module 2 is turned 180 degrees). 1 on.

Furthermore, in the embodiment, the width of the first outer rail bottom plate 211 is greater than the width of the first outer rail side plate 212, and the width of the first inner rail bottom plate 221 is greater than the width of the first inner rail side plate 222. Therefore, the guide rod lifting structure 200 of the present invention is fixed on the main board 11 of the support frame 1 by fixing the first outer rail bottom plate 211 having a larger width in the first slide rail module 2, thereby making the support frame The width of the side panel 12 of 1 may be designed according to the first outer rail side panel 212 having a smaller width in the first rail module 2, in other words, the thickness may have The effect is reduced. In contrast to the support device mentioned in the prior art, the track module is equal to 90 degrees relative to the first slide module 2 of the present case, that is, the side having the larger width is disposed on the side plate of the support frame. Therefore, the thickness of the supporting device cannot be effectively reduced.

3A and 3B are exploded views and isometric views of another embodiment of the proposed lifting structure of the guide. As shown in the figure, the lifting structure 300 with the guiding rod is suitable for supporting the display device (not shown). The lifting structure 300 with the guiding rod mainly comprises a supporting frame 1 and a first sliding rail module. 2a, a second slide rail module 2b, a trolley 3, two guide rods 4, two constant force springs 5, and a base 6. The difference from the first embodiment is that the second rail module 2b is disposed on the main board 11 of the support frame 1 substantially parallel to the first rail module 2a, and the two guide rods 4 are disposed. The first rail module 2a and the second rail module 2b are respectively fixed to the two sides of the trolley 3. In addition, other structural features are the same as those of the first embodiment, and thus will not be described again.

In summary, the lifting structure of the guide bar proposed by the present invention has a larger width of the outer rail of the slide rail module on the main board of the support frame, and no longer sets the slide rail module on the conventional support device. The side plate of the support frame, so that the width of the side plate of the support frame is not limited by the width of the outer rail bottom plate of the slide rail module, thereby effectively reducing the volume and weight of the support device, saving the materials used, and more complying with environmental protection demands And effectively save manufacturing costs.

The above embodiments are merely illustrative of the principles of the present invention and its effects, and are not intended to limit the present invention. Anyone familiar with the art can repair the above embodiments without violating the spirit and scope of this creation. change. Therefore, the scope of protection of this creation should be as listed in the scope of patent application described later.
