The connecting shaft is connected to the clutch locking module.
[0013] Optionally, the clutch locking module includes a base and a locking plate. The base is connected to the connecting shaft, and the first-stage folding arm is connected to the locking plate. The locking plate is slidably connected to the connecting shaft, and an electromagnet for attracting and controlling the locking plate is also provided between the base and the locking plate.

[0017] Optionally, the controller includes two independent control buttons, which are electrically connected to the two clutch locking modules respectively.
[0018] Compared with the prior art, this application has the following beneficial effects:
[0019] This application includes a primary folding arm and a secondary folding arm, wherein one end of the secondary folding arm is provided with a hanging frame; the other end is rotatably connected to the primary folding arm; a clutch locking module is also provided between the primary folding arm and the secondary folding arm, the clutch locking module being used to control the connection state between the primary folding arm and the secondary folding arm; a controller is also provided on the hanging frame, the controller being electrically connected to the clutch locking module;
[0020] In use, the display is mounted on the hanging frame, and the clutch locking module is in the closed state. At this time, the first-level folding arm and the second-level folding arm are in a state where they can rotate relative to each other. Medical staff can rotate the first-level folding arm and the second-level folding arm as needed to adjust the position of the hanging frame. When the hanging frame is adjusted to the correct position, the clutch locking module is closed by the controller to lock the first-level folding arm and the second-level folding arm, thereby preventing relative rotation between the first-level folding arm and the second-level folding arm and ensuring the stability of the hanging frame position.

[0034] Implementation method 1:
[0035] Reference Figures 1 to 5This embodiment, as an optional embodiment of this application, discloses a suspension folding arm with locking function, including a primary folding arm 1, a secondary folding arm 2, and a connecting frame 10. The primary folding arm 1 includes an arm rod, and along the axial direction of the arm rod, a primary connecting sleeve 5 is provided at one end of the arm rod, and an external sleeve 9 is provided at the other end. The secondary folding arm 2 includes an arm rod, and along the axial direction of the arm rod, a secondary connecting sleeve 6 is provided at one end of the arm rod, and a hanging frame 3 is connected to the other end. The hanging frame 3 is used to hang a display.
[0036] The connecting frame 10 includes an ear plate and a sleeve. A connecting shaft 1103 is snapped into the sleeve. A plurality of rolling bearings 7 are provided inside the outer sleeve 9. The connecting shaft 1103 is connected to each of the rolling bearings 7, thereby realizing the rotational connection between the connecting frame 10 and the first-stage folding arm 1.
[0037] Meanwhile, a number of rolling bearings 7 are provided inside the first-stage connecting sleeve 5, and a rotating shaft 8 is engaged inside the second-stage sleeve. The rotating shaft 8 is connected to each of the rolling bearings 7 respectively, so as to realize the rotational connection between the first-stage folding arm 1 and the second-stage folding arm 2.
[0038] A clutch locking module is provided between the first-stage folding arm 1 and the connecting frame 10, and between the first-stage folding arm 1 and the second-stage folding arm 2, and the two clutch locking modules have the same structure.
[0039] Each clutch locking module includes a base 12, a locking plate 13, and an electromagnet 14; the rotating shaft 8 is a hollow shaft, and a shaft end seat 11 is connected to the rotating shaft 8 by several connecting bolts.
[0040] The shaft end seat 11 includes a plug-in sleeve 1101, a connecting flange 1102, and a connecting shaft 1103. Along the axial direction of the shaft end seat 11, the plug-in sleeve 1101, the connecting flange 1102, and the connecting shaft 1103 are coaxially connected in sequence. The plug-in sleeve 1101 is inserted into the rotating shaft 8, and a flange plate is also provided on the rotating shaft 8. The connecting flange 1102 is tightly fitted to the flange plate and connected by several connecting bolts. The connecting shaft 1103 extends along the axial direction.
[0041] The base 12 is connected to the connecting shaft 1103 by several connecting bolts. The electromagnet 14 and the locking plate 13 are both sleeved on the connecting shaft 1103. The electromagnet 14 is located between the base 12 and the locking plate 13. The locking plate 13 is slidably connected to the connecting shaft 1103 and can also rotate around the connecting shaft 1103. In the vertical direction, the locking plate 13 is located at the lower end of the base 12.
[0042] A first connecting plate 15 is also provided on the first-stage folding arm 1. The first connecting plate 15 is connected to the locking piece 13 located on the same side by a number of connecting bolts.
[0043] A second connecting piece is also provided at one end of the first-stage folding arm 1 that connects to the second-stage folding arm 2. At the same time, the clutch locking module between the first-stage folding arm 1 and the second-stage folding arm 2 is installed in the aforementioned connection manner. The difference is that the locking piece in the clutch locking module is connected to the second connecting plate 16 by several connecting bolts.
[0044] When the clutch locking module is not in operation, the locking piece 13 separates from the base 12 under its own weight. At this time, the rolling bearing 7 and the rotating shaft 8 are in an operational state, thus enabling the rotation of the primary folding arm 1 or the secondary folding arm 2.
[0045] In operation, the electromagnet 14 will attract the locking piece 13, which will move towards the base 12 and eventually fit tightly against it. The friction between the base 12 and the locking piece 13 will fix the locking piece in place, preventing it from rotating around the connecting shaft 1103. Since the shaft end seat 11 is fixedly connected to the rotating shaft 8, and the base 12 is fixedly connected to the shaft end seat 11, and the locking piece is connected to the first-stage folding arm 1 via the first connecting plate 15, the locking of the locking piece by the base 12 will directly cause the rotating shaft 8 to be jammed. That is, the rolling bearing 7 and the rotating shaft 8 will not be able to rotate relative to each other, thereby locking the first-stage folding arm 1.
[0046] The clutch locking module between the first-level folding arm 1 and the second-level folding arm 2 is locked using the same principle;
[0047] Furthermore, a controller 4 is also provided on the hanging frame 3. The controller 4 includes two control buttons. The two control buttons are independent of each other and are electrically connected to the two clutch locking modules respectively. The working state of the clutch locking module is controlled by controlling the on-end state of the current of the electromagnet 14.
[0048] Furthermore, an adjusting nut 17 is threadedly connected to the free end of the connecting shaft 1103, and an adjusting pressure ring 18 is slidably sleeved on the connecting shaft 1103. Along the axial direction of the connecting shaft 1103, the adjusting pressure ring 18 is located between the locking piece 13 and the adjusting nut 17. The top end of the adjusting pressure ring 18 abuts against the locking piece 13, and its bottom surface abuts against the adjusting nut 17.
[0049] By controlling the adjusting nut 17, the position of the adjusting pressure ring 18 can be adjusted, thereby adjusting the distance between the locking plate and the base 12. On the one hand, this can control the corresponding speed of the clutch locking module; on the other hand, it can prevent the electromagnet 14 from failing to properly attract the locking plate due to excessive distance, thus ensuring the stability and reliability of the equipment.
[0050] Compared with the prior art, this application realizes the switching and control of the connection state between the first-level folding arm and the second-level folding arm through a clutch locking module. While ensuring the flexibility and adjustability of the folding arm, it also gives it a locking function, which further improves the stability and reliability of the folding arm.
[0051] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
