Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The following embodiments may be understood as explaining a local structure of the present invention individually, or may be understood as explaining a larger structure of the present invention through a combination of multiple embodiments.

[0025] Example 1

[0026] A ceiling suspension rod connection device, such as Figure 1-4 As shown, it includes a connecting rod 1, a fixing mechanism 2, and a connecting mechanism 3. The two connecting rods 1 are coaxially arranged opposite to each other and connected by the connecting mechanism 3. The connecting mechanism 3 includes a connecting unit 1 and a connecting unit 2. One end of the connecting unit 1 and the connecting unit 2 are hinged by a hinge shaft 309, and the other ends are respectively fixedly connected to the ends of the connecting rod 1 on the same side. One end of the connecting rod 1 away from the connecting mechanism 3 is connected to the fixing mechanism 2 by a two-way angle adjustment mechanism. The relative rotation direction of the connecting unit 1 and the connecting unit 2 defined by the hinge shaft 309 is staggered with the rotation direction of the connecting rod 1 located above defined by the two-way angle adjustment mechanism, thereby realizing the adjustment of the lower connecting rod, i.e., the fixing mechanism at the bottom in three directions, thereby enabling the device to be suitable for the construction of inclined ceilings.

[0027] Example 2

[0028] like Figure 2 , 3 As shown, the fixing mechanism 2 includes a fixing plate 201, which is a square plate. Connecting arms 202 extend outward along the diagonal direction at the four corners of the bottom end of the fixing plate 201. The ends of the connecting arms 202 are provided with connecting holes for connecting and fixing with the structural top plate or the suspended ceiling plate.

[0029] Example 3

[0030] like Figure 2 , 3 As shown, the bidirectional angle adjustment mechanism comprises a mounting plate 203 and a U-shaped seat 206 which are relatively arranged on the upper surface of a fixed plate 201, a cubic rotating plate 205 with upper and lower ends open is arranged between the two mounting plates 203, arc-shaped slide grooves 2052 are respectively arranged relatively on two groups of opposite side walls of the rotating plate 205, that is, two arc-shaped slide grooves 2052 arranged relatively are arranged on each group of opposite side walls; bolt holes 2051 are arranged above the arc-shaped slide grooves 2052, and the arc-shaped slide grooves 2052 and bolt holes 2052 of the two groups of opposite side walls are staggered to prevent the bolts passing through the opposite arc-shaped slide grooves or opposite bolt holes from interfering with each other;

[0031] like Figure 2 As shown, the mounting plate 203 is provided with a first arc groove (not marked in the figure) and a first through hole (not marked in the figure), the first through hole is coaxially opposite to a bolt hole 2051 of a group of side walls of the rotating plate 205, the first arc groove is of the same size and structure as the arc slide groove 2052, and is opposite to the arc slide groove 2052 on the side wall of the rotating plate 205; the rotating plate 205 is separated from the upper surface of the fixed plate 201, so that it is convenient to rotate relative to the mounting plate; the mounting plate 203 passes through the first through hole and the relative The first bolt 204 of the bolt hole and the second bolt 207 that penetrates the first arc groove and the corresponding arc groove 2052 are connected, and the ends of the first bolt 204 and the second bolt 207 are both threaded with a first locking nut; it can be understood that the rotating plate 205 can use the first bolt 204 as a rotating shaft to rotate a certain angle relative to the mounting plate 203, and then the first bolt 204 and the second bolt 207 are locked by the first locking nut, so that the rotating plate 203 is fixed at this angle; in this way, the adjustment of the first rotation direction angle is achieved;

[0032] like Figure 2As shown, the U-shaped seat 206 spans across both sides of the rotating plate 205, and a second arc groove (not marked in the figure) and a second through hole (not marked in the figure) are provided on the side wall of the U-shaped seat 206. The second arc groove is consistent in size and shape with the arc groove 2052 on the other side wall of the rotating plate 205 and is arranged oppositely. The second through hole is coaxially opposite to the bolt hole 2051 on the opposite side wall of the rotating plate 205. The U-shaped seat 206 is connected by a third bolt 208 passing through the second through hole and the corresponding bolt hole 2051 and a fourth bolt passing through the second arc groove and the opposite arc groove 2052. 209 is connected to the rotating plate 205, and the ends of the third bolt 208 and the fourth bolt 209 are both threaded with a second locking nut (not marked in the figure). The bottom end of the U-shaped seat 206 is detached from the upper surface of the fixed plate 201. It can be understood that the U-shaped seat can rotate relative to the rotating plate 205 with the third bolt 208 as the rotating axis, and the second arc groove limits the range of relative rotation. When the rotation angle is reached, the third bolt and the fourth bolt are locked by the second locking nut, thereby achieving the fixing of the rotation angle between the U-shaped seat and the rotating plate, and further achieving the angle adjustment in the second rotation direction.

[0033] Example 4

[0034] like Figure 2 As shown, the distance A between the bottom end of the U-shaped seat 206 and the upper surface of the fixed plate 201, the distance B between the rotating plate 205 and the upper surface of the fixed plate 201, and the distance C between the mounting plate 203 and the rotating plate 201 are sufficient to: enable the rotating plate 205 to rotate relative to the mounting plate 203 with the first bolt 204 as the rotating axis, and on this basis, enable the U-shaped seat 206 to rotate relative to the rotating plate 205 with the third bolt 208 as the rotating axis; that is, the mounting plate cannot interfere with the rotation of the U-shaped seat, and the distance between the mounting plate and the rotating plate can be limited by providing limit blocks on the outer walls of the first bolt and the third bolt (not shown in the figure); the first locking nut and the second locking nut are used to relatively fix the rotating plate 205 and the mounting plate 203, as well as the rotating plate 205 and the U-shaped seat 206 after rotating to the desired angle.

[0035] Example 5

[0036] like Figure 2 , 5 As shown, when the two connecting rods 1 are coaxial and perpendicular to the surface of the fixing plate 201, the axes of the first bolt 204 and the third bolt 208 are perpendicular to each other in a top view, and the axis of the hinge shaft 309 passes through the intersection of the axes of the first bolt 204 and the third bolt 208, and forms a 45-degree angle with the axes of the first bolt 204 and the third bolt 208 in a top view. The axes of the first bolt 204 and the third bolt 208 define the rotation direction of the upper connecting rod; the axis of the hinge shaft defines the rotation direction of the lower fixing mechanism.

[0037] Example 6

[0038] like Figure 1 , 2 As shown, a threaded hole is provided at the top of the U-shaped seat 206, and one end of the connecting rod 1 away from the connecting mechanism 3 is screwed to the threaded hole.

[0039] Example 7

[0040] like Figure 4 As shown, the structures of the connection unit 1 and the connection unit 2 are the same, and respectively include a first connection tube 301, a second connection tube 305, a clamping plate 306, and a sleeve 307. The end of the first connection tube 301 away from the hinge shaft 309 is connected to the end of the second connection tube 305 through a connecting rod 304 evenly distributed around the axis. The other end of the second connection tube 305 is evenly distributed around the axis with a plurality of arc-shaped clamping plates 306. A screw tooth structure is provided on the outer wall of the clamping plate 306 (that is, the screw tooth structures of the plurality of clamping plates constitute an intermittent external thread). The inner wall of the sleeve 307 is provided with an internal thread, and the internal thread is screwed with the screw tooth structure. The thickness of the clamping plate 306 gradually decreases from the end of the second connection tube 305 to the outside. The inner wall of the clamping plate 306 and the inner wall of the second connection tube 305 are located in the same curved surface. The first connection tube 301 and the second connection tube 305 are coaxial. When the sleeve is rotated, the wall thickness of the clamping plate gradually increases, so the degree to which the clamping plate is compressed inward by the sleeve increases continuously, so that the clamping plate can be adapted to be fixed to connecting rods of different diameters.

[0041] Example 8

[0042] like Figure 4 As shown, the ends of the first connecting tubes 301 adjacent to the connecting unit 1 and the connecting unit 2 are respectively provided with hinge plates 308, and the two hinge plates 308 are attached to each other and hinged by a hinge shaft 309. The hinge shaft is a bolt structure, and the end of the bolt structure is threaded with a third locking nut.

[0043] Example 9

[0044] like Figure 4 As shown, a clamp structure 302 is provided between the first connecting tube 301 and the second connecting tube 305 and on the inner side of the connecting rod 304. The end of the clamp structure 302 is provided with a folding plate that folds outward and passes through the adjacent connecting rod 304. The two folding plates fit together and are locked together by a bolt and nut assembly.

[0045] In this embodiment, the connecting rod is fixed by the clamping hoop structure and the clamping plate.

[0046] The working principle of this new model:

[0047] When in use, the upper fixing mechanism is fixedly connected to the structural top plate through the expansion bolts passing through the connection holes, so that the fixing plate fits with the top plate, then the angle of the rotating plate of the upper fixing seat relative to the mounting plate and the angle of the rotating plate relative to the U-shaped seat are adjusted, and the first locking nut is locked to achieve the angle fixation of the upper connecting rod, and then the angle between the connecting unit 1 and the connecting unit 2 is adjusted according to the predetermined position of the ceiling plate, and the third locking nut is used to lock and fix the lower connecting rod. Finally, the posture of the lower fixing mechanism is adjusted according to the angle of the lower ceiling plate (the same as the adjustment of the upper fixing mechanism), the bottom of the fixing plate of the lower fixing mechanism is fit with the upper end of the ceiling plate, and then the ceiling plate is fixedly connected to the fixing plate of the lower fixing mechanism by screws passing through the connection holes, and the first locking nut and the second locking nut of the lower fixing mechanism are tightened to achieve the positioning of the entire device and the ceiling plate.
