[0016] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0018] Please see Figure 1-4 The present invention relates to a multifunctional rotatable surgical lamp holder, comprising: a support shaft 1, a bearing sleeve 3, an inner shaft sleeve 4, and a ball chain 5 mounted on the outer side of the support shaft 1 to form a bearing seat for rotational movement; an integrally formed liquid reservoir 6 on the outer side of the bearing sleeve 3; and a lubricating element 7 for communication between the liquid reservoir 6 and the bearing sleeve 3, wherein the lubricating element 7 is in contact with the ball chain 5 for continuous lubrication.

[0019] Please see Figure 1 The support shaft 1 has an integrally formed shaft rod 11 and a top plate 2 at both ends. The diameter of the shaft rod 11 is smaller than that of the support shaft 1, and its axis coincides with the axis of the support shaft 1. The integrated structure of the shaft rod 11 and the top plate 2 optimizes the mechanical transmission path, reduces the overall weight while ensuring the stability of the support shaft 1, and meets the lightweight requirements of operating room equipment. The design of the shaft rod 11 and the support shaft 1 having the same axis stabilizes the center of force when the inner bushing 4 rotates, and increases the stability of the connection between the support shaft 1 and the shaft rod 11.

[0020] Please see Figure 1The inner bushing 4 is fixedly connected to the outside of the shaft 11. The bearing sleeve 3 is fitted onto the outside of the inner bushing 4. The end of the bearing sleeve 3 away from the support shaft 1 is sealed. The diameter of the outer side of the bearing sleeve 3 is equal to the diameter of the support shaft 1. A groove 31 is provided on the inner side of the bearing sleeve 3. A groove with a diameter equal to the diameter of the groove 31 is provided on the outer side of the inner bushing 4. The axis of the outer groove of the inner bushing 4 coincides with the axis of the groove 31. The ball chain 5 is slidably connected between the groove 31 and the outer groove of the inner bushing 4. The sealed end of the bearing sleeve 3 away from the support shaft 1 effectively prevents lubricating oil leakage and dust intrusion. The inner bushing 4, the ball chain 5, and the bearing sleeve 3 are all connected together. The ball chain 5 and the bearing sleeve 3 are components of the bearing housing. Traditionally, a complete bearing is installed inside the bearing housing, but this application retains the rotating collar inside the bearing housing and removes the outer rotating collar, which is slidably connected to the bearing sleeve 3 to form a complete bearing housing. The bearing housing, composed of the inner sleeve 4, the ball chain 5 and the bearing sleeve 3, allows the adjustable arm of the shadowless lamp to be rotated and adjusted directly with the shaft 11 as the center. Since the outer collar of the traditional bearing housing has been removed, the lubricating components 7 and lubricating oil in the liquid reservoir 6 can directly contact the ball chain 5 for lubrication, eliminating the need for disassembly when lubricating the joints of the shadowless lamp.

[0021] Please see Figure 4 The liquid storage tank 6 is integrally formed on the outside of the bearing sleeve 3. The liquid storage tank 6 has an inlet 62 on the side near the top plate 2. The inner side of the inlet 62 is threaded. The threaded inlet 62 is connected and fixed with the oil tank 8, which facilitates the removal and replacement of the oil tank 8 and simplifies the joint lubrication process of the adjustable shadowless lamp.

[0022] Please see Figure 3The inner wall of the liquid storage tank 6 has an outlet 61 near the support shaft 1. The outlet 61 is semi-circular at the end near the support shaft 1 and connects to the slide groove 31. The lubricating element 7 is fixedly connected to the inner side of the outlet 61. The lubricating element 7 is semi-circular at the end near the support shaft 1 and its size is equal to that of the semi-circular end of the outlet 61. The semi-circular end of the lubricating element 7 extends to the inner side of the slide groove 31, and the other end of the lubricating element 7 extends to the outer side of the outlet 61. The lubricating element 7 is a nitrile rubber sponge that can be in contact with lubricating oil for a long time without swelling or degradation. The semi-circular end of the lubricating element 7 can smoothly fit with the rotating ball chain 5. When the bearing sleeve 3 drives the cantilever of the shadowless lamp to move through the ball chain 5, the ball chain 5 will... During rotation, the lubricant 7 is squeezed, causing the oil absorbed by the lubricant 7 to overflow and adhere to the surface of the ball chain 5. As the ball chain 5 moves, the oil adheres to various parts, forming lubrication. The lubrication maintenance gap is related to the usage gap of the shadowless lamp cantilever. Lubrication during the use of the shadowless lamp cantilever ensures smooth operation. Since the lubricant 7 is a nitrile rubber sponge, it has the elasticity and compressibility of a sponge. When the ball chain 5 squeezes the lubricant 7, the lubricant 7 will be smoothly compressed and oiled without affecting the rotation of the ball chain 5. The oil output frequency of the lubricant 7 is related to the ball spacing of the ball chain 5. A larger ball spacing results in a lower oil output frequency, while a smaller ball spacing results in a higher oil output frequency.

[0023] Please see Figure 2 The inner thread of the inlet 62 is connected to the oil tank 8.
