[0037] Referring to Figures 1 to 3 , the lifting suspension frame includes a frame 1, a suspension assembly 2 and a support assembly 3, wherein:

[0038] The frame 1 is of rectangular structure, providing lifting support for the suspension assembly 2, including vertical rails 11 on both sides, a center column 12 and upper and lower frame beams 13 and 14 connecting the upper and lower ends; the center column 12 is a hollow profile, which not only strengthens the support of the rectangular frame, but also provides assembly space for the screw 7 and the nut block 71. Further, the vertical rail 11 is mainly a U-shaped profile, and a groove 111 larger than a semicircle is formed on both sides of the notch, and a light pole guide rail 112 is embedded in the groove 111.

[0039] The suspension assembly 2 includes a lifting frame 21 and a suspension plate 22 mounted on the vertical surface of the lifting frame 21. The lifting frame 21 is slidably positioned on the vertical rail 11 on both sides via track wheels 23. The suspension plate 22 provides a suspension position for the flat panel equipment. More specifically, the suspension plate 22 includes a support frame 221 and a detachable fixing strip 222. The fixing strip 222 has a groove machined on its back, with a barb 2221 on the upper edge of the groove and a set screw 2223 screwed onto the right-angled flap 2222 on the lower edge. The suspension plate 22 is directly locked to the lifting frame 21 by means of the support frame 221. The fixing strip 222 is used to lock onto the pre-drilled holes on the back of the flat panel or other equipment. During suspension, the barb 2221 is used to hang on the upper edge of the support frame, and then the set screw 2223 is rotated to abut against the lower edge of the support frame, thus completing the suspension of the equipment. Figure 2 , Figure 3 and Figure 4 .

[0040] In addition, the suspension assembly 2 is slidably positioned on the vertical track 11 by the track wheel 23. In addition to the structure shown in the figure, a double row of track wheels can also be used to clamp a smooth rod track; or, conventional sliding guidance schemes such as linear guide rails and linear bearings can be used.

[0041] The support assembly 3 supports the height of the suspension assembly 2 and can be adjusted for lifting and self-positioning with relatively light force. It includes an upper crossbeam 31, a lower crossbeam 32, and a folding triangular assembly 33 supporting the two, as well as a first spring 4 and a second spring 5. The folding triangular assembly 33 is located between the upper crossbeam 31 and the lower crossbeam 32 to adjust the distance between the upper crossbeam 31 and the lower crossbeam 32. The first spring 4 is located between the folding triangular assembly 33 and the upper crossbeam 31 and / or the lower crossbeam 32. One end of the second spring 5 is located on the frame 1, and the other end is hoisted to the suspension assembly 2 after being reversed by a pulley group 6 located on the frame 1. The first spring 4 and the second spring 5 together maintain the load-bearing capacity of the suspension assembly 2.

[0042] Due to the load-bearing capacity and the weight of the components, the support assembly 3 will always rest against the lower side of the suspension assembly 2, transferring the weight to the frame 1. To improve overall rigidity, the upper crossbeam 31 of the support assembly can be fixed to the lifting frame 21 of the suspension assembly, while the lower crossbeam 32 is fixed to the lower frame beam 14 of the frame, ensuring synchronous lifting and adjustment. Therefore, in this example, the bottom edge of the lifting frame 21 is directly supported by the upper crossbeam 31.

[0043] As a preferred solution, two sets of left and right corresponding folding triangle assemblies 33 are arranged between the upper cross beam 31 and the lower cross beam 32, the folding triangle assembly 33 is composed of two or more even number of rod members hinged at the ends, the upper rod member 331 at the top end is hinged to the upper cross beam 31, and the lower rod member 332 at the lower end is hinged to the lower cross beam 32; the first spring 4 is two or four, two first springs 4 are selected and arranged between the upper cross beam 31 and the upper rod member 331 of the folding triangle assembly or between the lower cross beam 32 and the lower rod member 332 of the folding triangle assembly; four first springs 4 are selected in the figure and arranged between the upper cross beam 31 and the upper rod member 331 of the folding triangle assembly and between the lower cross beam 32 and the lower rod member 332 of the folding triangle assembly; the first spring 4 is used to maintain the two sets of folding triangle assemblies 33 open or folded to any state. That is, the first spring 4 generates a self-positioning force, and the number of springs is selected according to the load-bearing requirement, and the behavior of arranging springs in parallel is not excluded.

[0044] In order to better form a variable triangle between the rod members in the folding triangle assembly 33 and the first spring 4 and the upper and lower cross beams, a triangular area 311 is machined downward at both ends of the upper cross beam 31 to provide the hinge of the two upper rod members 331 of the folding triangle assembly and the two upper first springs 4; the lower cross beam 32 is correspondingly machined upward at both ends to provide the hinge of the two lower rod members 332 of the folding triangle assembly and the two lower first springs 4.

[0045] Further, the lower end of the second spring 5 is hung on a nut block 71, and the upper end of the extended flexible rope 51 is hung on the lifting frame 21 after passing through the pulley block 6; the nut block 71 slides against the center column 12, and the screw rod 7 rotatably positioned in the center column 12 positions and adjusts the pre-tightening force of the second spring 5; the pulley block 6 includes two or more fixed pulleys 61 and at least one movable pulley 62, the upper support shaft 611 supporting the fixed pulley 61 is positioned on the center column 12, and the lower support shaft 621 supporting the movable pulley 62 is movably positioned in the vertical slot 121 of the center column 12 and can slide up and down in the vertical slot 121.

[0046] More specifically, the upper support shaft 611 and the lower support shaft 621 are further provided with a guide piece 63 at the end away from the center column 12, the guide piece 63 is fixed on the frame 1 and is provided with shaft holes and vertical slots corresponding to the center column 12 and the vertical slot 121, which jointly constrain the upper support shaft 611 and the lower support shaft 621.

[0047] The two second springs 5 are symmetrically or correspondingly arranged on both sides of the center column 12 and hung on the same nut block 71, and the pre-tightening force of the two second springs 5 is adjusted synchronously by the screw rod 7. Arranging two second springs 5 can double the weight of the hoisting, and sharing a set of screw rod 7 and nut block 71 for adjusting the pre-tightening force can simplify the structure and bring convenience to the use and operation.

[0048] As a preferred solution, the lifting frame 21 in the suspension assembly and the support assembly 3 are both front and rear elevation symmetrical or corresponding structure, the middle column 12 of the frame 1 and the second spring 5 pass through the through hole reserved in the center of the support assembly 3 and the lifting frame 21; the corresponding folding triangular assembly 33 in the front and rear elevations is associated by long rivets 333, and the first spring 4 is suspended on the corresponding long rivet 333.

[0049] The greatest feature of the scheme is to use the folding triangular assembly 33, which can keep the two ends of the rod hinged to the upper cross beam 31 and the lower cross beam 32 unchanged during unfolding and folding, and its instability is overcome by the association of the two corresponding folding triangular assemblies 33 on both sides, which is different from the four-bar linkage. Secondly, the first spring 4 has a large included angle with the lifting direction, and the suspension assembly 2 can be adjusted within the designed range, and the extension variable is relatively small, which can work within the constant force range of the spring. In this structure, the first spring 4 not only supports the folding triangular assembly 33 to bear the weight, but also has a self-positioning function, that is, it can hover at a certain height. The second spring 5 suspends the suspension assembly 2 after passing through the pulley block 6. The number of movable pulleys is the ratio of the lifting range of the suspension assembly to the extension amount of the second spring 5, and the constant force range of the second spring 5 can be controlled through the design of the pulley block. According to the weight bearing requirement of the suspension assembly 2, the more the weight, the more the number of springs required, or the greater the elastic coefficient of the spring selected. The second spring 5 can be regarded as a counterweight of the suspension assembly load, and the first spring 4 provides a self-positioning force.

[0050] During the lifting adjustment process, a small external force can overcome the positioning force of the first spring 4, so that the suspension load can be adjusted at will. Even if the spring changes the spring force to some extent during deformation, as shown in the figure, the suspension assembly 2 is at the highest position, and the first spring 4 and the second spring 5 are both in the contracted state. When it is at the lowest position in the afternoon, the first spring 4 and the second spring 5 are both in the stretched state, and the elastic force is increased; but because the angle between the rod of the folding triangular assembly 33 and the first spring 4 is smaller, or the angle between the first spring 4 and the horizontal upper and lower cross beams is smaller, the vertical component force is also reduced, and the increased force of the second spring 5 forms a complement, so that the external force required for adjustment is maintained at a constant value range.

[0051] The lifting suspension frame body can be independently fixed to the vertical surface of a fixed object such as a wall, and can meet the function of lifting adjustment. In order to meet the purpose of mobile occasions and shared resources, a mobile suspension frame can be configured.

[0052] Referring to Figure 4 and Figure 5 , a mobile suspension frame, comprising the above-mentioned lifting suspension frame, wherein: the mobile suspension frame further comprises a bottom plate 8, double columns 81 erected on the bottom plate 8, and a lock roller 82 installed at the bottom of the bottom plate 8, and the lifting suspension frame is directly locked between the double columns 81 by means of the frame 1, and also provides the association between the double columns 81, so as to realize the mobile use and share the resources.
