The rotating shaft assembly 2 includes a rotating support element 21, the rotating support element 21 including a first rotating part 211 and a second rotating part 212 rotating about a second direction. The rotating part 211 is fixedly connected to the first support arm 11, the second rotating part 212 is fixedly connected to the second support arm 12, and the fixing component 3 includes a plurality of fasteners 31, which are respectively disposed on both sides of the connection position between the second support arm 12 and the second rotating part 212 in a first direction. The two sides include a first side 32 and a second side 33 disposed opposite to each other. The first side 32 is disposed close to the first support arm, and the number of fasteners 31 disposed on the second side 33 is greater than the number of fasteners 31 disposed on the first side 32.

[0032] The technical solution of this utility model includes a support arm assembly 1, a rotating shaft assembly 2, and a fixing assembly 3 in the rotating arm structure 100. The support arm assembly 1 includes two arms extending in at least a first direction, the two arms including a first arm 11 and a second arm 12, the first arm 11 being rotatably connected to the second arm 12 about a second direction. The rotating shaft assembly 2 includes a rotating support element 21, the rotating support element 21 including a first rotating part 211 and a second rotating part 212 rotating about a second direction, the first rotating part 211 being fixedly connected to the first arm 11, the second rotating part 212 being fixedly connected to the second arm 12. The fixing assembly 3 includes a plurality of fasteners 31, the plurality of fasteners 31 being disposed on both sides of the connection position between the second arm 12 and the second rotating part 212 in the first direction, wherein the two sides include a first side 32 and a second side 33 disposed opposite to each other, the first side 32 being disposed close to the first arm 11, and the number of fasteners 31 disposed on the second side 33 being greater than the number of fasteners 31 disposed on the first side 32. This configuration, through the use of the rotating shaft assembly 2, allows the rotating arm structure 100 to rotate stably and flexibly within the medical pendant bridge, improving the flexibility of infusion. The second arm 12 is securely connected to the second rotating part 212 by multiple fasteners 31, and more fasteners 31 are provided on the second side 33 to enhance the stability of the connection between the first arm 11 and the second arm. In particular, when the first arm 11 is bearing heavy loads, it can reduce the occurrence of warping at the rotating joint, thereby improving the stability of the rotating arm structure 100 and the safety of the infusion stand.

[0033] In this embodiment, the arrangement of the rotating support element 21 is not specifically limited. For example, in some embodiments, the rotating support element 21 may include a shaft extending along a second direction. The first support arm 11 and the second support arm 12 are respectively passed through the two ends of the shaft to form the first rotating part 211 and the second rotating part 212. Bearings are sleeved on the outer peripheral wall of the shaft to allow the first support arm 11 and the second support arm 12 to rotate. The structure is simple, easy to implement, and enables the first support arm 11 and the second support arm 12 to rotate stably around the shaft.

[0034] The fastener 31 can be set in various ways, such as bolts, nuts, pins, etc.

[0035] Specifically, in one embodiment, a threaded hole 4 is provided at the connection position between the second support arm 12 and the second rotating part 212; the fastener 31 includes a fixing bolt 311, which is screwed into the threaded hole 4. This arrangement, through the cooperation of the threaded hole 4 and the bolt, improves the stability and reliability of the connection between the first support arm 11 and the second support arm 12. It also simplifies the assembly process and improves the durability and safety of the entire device.

[0036] Of course, in some embodiments, the number of fasteners 31 is not specifically limited. Specifically, in this embodiment, the plurality of fasteners 31 includes at least a first fastener 312, a second fastener 313, a third fastener, and a fourth fastener. The first fastener 312 is disposed on the first side 32, and the second fastener 313, the third fastener, and the fourth fastener are disposed on the second side 33. The third fastener and the fourth fastener are disposed on opposite sides of the second fastener 313. Thus, by setting the plurality of fasteners 31, with the first fastener 312 located on the first side 32, and the second fastener 313, the third fastener, and the fourth fastener located on the second side 33, and with the third fastener and the fourth fastener respectively located on both sides of the second fastener 313, the stability and firmness of the connection between the first support arm 11 and the second support arm 12 are further improved. By distributing more of the fasteners 31 on one side of the second support arm 12, when the first support arm 11 bears a large force, the connection between the second support wall and the first support arm 11 can withstand a greater force, reducing the warping of the rotating parts between the first support arm 11 and the second support wall.

[0037] Furthermore, to facilitate the use of the rotating arm structure 100, in one embodiment, a first mounting hole 5 is provided at the end of the first support arm 11 away from the fixing component 3.

[0038] In one embodiment, a second mounting hole 6 is provided at the rotatable connection between the first support arm 11 and the second support arm 12, and the rotating shaft assembly 2 is disposed within the second mounting hole 6. Thus, by providing the second mounting hole 6, the rotating shaft assembly 2 can be securely installed at the rotatable connection between the first support arm 11 and the second support arm 12, ensuring both rotational flexibility and improved rotational stability. Simultaneously, the second mounting hole 6 simplifies and expedites the installation process of the rotating shaft assembly 2.

[0039] In one embodiment, the first rotating part 211 is connected to the first support arm 11 via a fixing member 7. Thus, through the connection of the fixing member 7, the first rotating part 211 can be stably combined with the first support arm 11, reducing swaying or deviation during rotation, enhancing the stability of the rotating arm structure 100, and making the first rotating part 211 rotate more smoothly and steadily.

[0040] It is understood that the fixing component 7 can be provided as a pin, a rod, or the like.

[0041] In one embodiment, a fixing hole 8 is provided at the center of the connection between the first rotating part 211 and the first support arm 11, and the fixing member 7 is disposed in the fixing hole 8. Thus, by providing the fixing hole 8, the fixing member 7 can be accurately positioned at the center of the connection between the first rotating part 211 and the first support arm 11, further enhancing the stability and accuracy of the connection.

[0042] In one embodiment, the swing arm structure 100 further includes a gasket 10, which is sleeved on the outer peripheral wall of the fixing member 7 and abuts against the fixing member 7. Thus, the gasket 10 not only increases the contact area between the fixing member 7 and the first rotating part 211 and the first support arm 11, but also provides cushioning and shock absorption, further improving the stability and durability of the swing arm structure 100.

[0043] The gasket 10 may be made of wear-resistant and corrosion-resistant materials to extend its service life and prevent performance degradation due to friction or corrosion during use.

[0044] In one embodiment, a removable cover plate 9 is provided at the opening of the fixing hole 8. Thus, the fixing hole 8 can be closed by removing the cover plate 9, reducing the entry of dust, debris, etc., into the fixing hole 8, ensuring the cleanliness of the swing arm structure 100 and the integrity of its internal parts. Furthermore, the removable design of the cover plate 9 facilitates the replacement or maintenance of the fixing component 7 by the user, improving the maintainability and ease of use of the swing arm structure 100.

[0045] In one embodiment, a retaining plate 91 is provided at one end of the cover plate 9 near the fixing hole 8, and a retaining groove 92 is provided on the inner wall of the fixing hole 8. The retaining groove 92 cooperates with the retaining plate 91. In this way, the cover plate 9 can be firmly fixed at the opening of the fixing hole 8 by the engaging action of the retaining plate 91 and the retaining groove 92, reducing the risk of the cover plate 9 accidentally falling off during use.
