Simultaneously, two ends of the inclined support frame 1 are respectively fixed with a barbell hanging rod 11.
The inclined support frame 1 is hollow and tubular, a hidden connecting rod limiting mechanism is arranged in the tube, and the inclined support frame 1 can be a round tube or a square tube. As shown in fig. 1, the hidden link limiting mechanism includes a link 9, at least one limiting frame, a rotating frame 4 and an adjusting handle 5, wherein the link 9, the limiting frame and the rotating frame 4 are all disposed in the inclined supporting frame 1. The number of the limiting frames is determined according to the length of the inclined supporting frame and the requirements in the actual use process. In this embodiment, two limiting frames, i 7 and ii 8, are provided. The pipe bottom opening 18 is arranged at the pipe bottom of the inclined support frame 1 and corresponds to the limiting frame, and the limiting frame can rotate out from the pipe bottom opening. The lower part of the pipe of the inclined support frame 1 is correspondingly provided with a limiting frame and a rotating part is provided with a fixed sleeve which is positioned at two sides of the inclined support frame 1 and symmetrically arranged.
The rotating frame 4 is arranged at the bottom of the connecting rod 9, the rotating frame 4 comprises two vertical plates I which are arranged in parallel and a transverse pipe I connected with the two vertical plates I, the bottom of the connecting rod 9 is positioned between the two vertical plates I, the top ends of the two vertical plates I are hinged with the bottom of the connecting rod 9, and the bottom ends of the two vertical plates I are fixedly connected through the transverse pipe I. The adjusting handle 5 comprises an adjusting handle frame and an adjusting handle shaft, the adjusting handle shaft is fixedly connected with one end of the adjusting handle frame, and the other end of the adjusting handle shaft is arranged in the transverse pipe I and the fixing sleeve III 103. The adjusting handle shaft is fixedly connected with the transverse tube I through an inner hexagonal flat end set screw 14 and hinged with the fixed sleeve III 103, so that the rotating frame is hinged with the inclined support frame 1. Since the adjusting handle 5 is connected with the connecting rod 9 through the rotating frame 4, when the adjusting handle 5 is rotated, the connecting rod 9 is driven to rotate in the inclined support frame 1.
The limiting frame I7 and the limiting frame II 8 are arranged along the axial interval of the connecting rod, a fixed sleeve II 102 is arranged at the corresponding position of the limiting frame I7 on the inclined supporting frame 1, and a fixed sleeve I101 is arranged at the corresponding position of the limiting frame II 8. Because the structures of the limiting frame I7 and the limiting frame II 8 are the same, and the connection modes of the limiting frame I7 and the connecting rod 9 as well as the fixing sleeve are the same, the limiting frame II 8 and the connection relation between the limiting frame II 8 and the connecting rod as well as the fixing sleeve are described in detail in the embodiment, and the limiting frame I7 is not repeated.
As shown in fig. 3, the limiting frame ii 8 includes two parallel vertical plates ii and a transverse pipe ii connecting the two vertical plates ii, the connecting rod 9 is located between the two vertical plates ii, the bolt 13 passes through the top ends of the two vertical plates ii and the connecting rod located between the two vertical plates ii, and the top ends of the two vertical plates ii are hinged with the connecting rod 9 through the nut 14. The bushing 12 is arranged at the joint of the bolt 13 and the connecting rod 9, the joint surface of the bolt 13 and the connecting rod 9 can be protected by arranging the bushing 12, and the limiting function is achieved, and the bushing 12 is positioned between the two vertical plates II, so that the bushing 12 can prevent the nut 14 from excessively rotating to cause the deformation of the limiting frame.
The middle parts of the two vertical plates II are fixedly connected through a transverse pipe II, a rotating shaft 16 is arranged in the transverse pipe II, and the rotating shaft 16 is fixedly connected with the transverse pipe II through an inner hexagonal flat end set screw 14.
