[0026] Please refer to Figures 1-5The detachable cantilever wire passing device for surgical lamp comprises a main shaft assembly 1, at least one guide ring 2 and at least one horizontal arm assembly 3, characterized in that the main shaft assembly 1, the guide ring 2 and the horizontal arm assembly 3 are sequentially sleeved from inside to outside; the main shaft assembly 1 comprises a main shaft rod 11, the main shaft rod 11 is provided with a first wire passing cavity 111, and the side of the main shaft rod 11, which faces the horizontal arm assembly 3, is provided with a first wire passing hole 112; the guide ring 2 is provided with a second wire passing hole 21 matched with the main shaft rod 11, and the horizontal arm assembly 3 is internally provided with a second wire passing cavity (not marked in the figure), so that the wire can be sequentially connected to the surgical lamp from the main shaft assembly 1, the guide ring 2 and the horizontal arm assembly 3.

[0027] Specifically, the cantilever wire passing device of the utility model is mainly used for surgical lamp, and the power cord of the general surgical lamp needs to pass through the ceiling, the rotating shaft, the cantilever, the spring arm and other components to reach the surgical lamp, and the rotating shaft and the cantilever constitute a general form of the cantilever wire passing device, as the rotating shaft and the cantilever need to be rotated to adapt to different requirements of the operating room, the wire passing through these components in sequence is prone to winding and breakage, and in order to protect the power cord and other wires, the utility model sets a cantilever wire passing device, and the power cord and other wires pass through the inside of various components to avoid winding and breakage, and meanwhile, the guide ring and other components are arranged, so that the wire can pass through various components more smoothly to connect the surgical lamp.

[0028] More specifically, the power cord and other wires pass through the ceiling into the first wire passing cavity 111 of the main shaft rod 11, as the guide ring 2 is sleeved outside the main shaft rod 11, then the first wire passing hole 112 and the second wire passing hole 21 are used to enter the second wire passing cavity (not marked in the figure) in the horizontal arm assembly 3, the guide ring 2 can play a guiding role, as the guide ring 2 is arranged at the joint of the main shaft rod 11 and the horizontal arm assembly 3, can also play a certain buffering role, and can reduce the breakage of the power cord and other wires, then the wire enters the second wire passing cavity (not marked in the figure) and then extends downward until reaches the lamp body of the surgical lamp, compared with the previous wire passing mode, this mode can not only avoid the exposure of the wire to the outside to cause damage, knotting and safety problems, but also avoid the setting of the wire in the inside to be stuck in the device area due to the absence of a certain buffering device, thereby causing damage to the wire.

[0029] In addition, more than one cross arm assembly 3 can be installed on one main shaft assembly 1, and the specific number is determined according to user requirements and the length of the main shaft rod 11. Generally, as many cross arm assemblies 3 as there are guide rings 2 are placed. Because the cross arm assembly 3 can rotate relative to the main shaft assembly 1, the cross arm assembly 3 can be on the same side or on different sides to meet the needs of the wire layout in the operating room. When multiple wires need to enter different cross arm assemblies 3, they can enter different cross arm assemblies 3 according to the needs of the guide ring 2 to achieve different functions.

[0030] In an embodiment, two cross arm assemblies 3 and two guide rings 2 are provided, and one main shaft rod 11 can be matched with three cross arm assemblies 3 and guide rings 2. This number is not a limitation on the scope of protection.

[0031] In some embodiments of the present application, the cross arm assembly 3 includes a clamping portion 32, a connecting portion 33, and an extension portion 34 connected in sequence. The clamping portion 32 is sleeved on the main shaft rod 11. The connecting portion 33 is provided with a second wire passing cavity (not marked in the figure). The extension portion 34 is provided with a third wire passing cavity 341. The extension portion 34 is used to connect with the spring arm.

[0032] Specifically, the clamping portion 32 of the cross arm assembly 3 is sleeved together with the guide ring 2 and the main shaft rod 11. The clamping portion 32, the connecting portion 33, and the extension portion 34 are all hollow, which facilitates the wire passing. The clamping portion 32 can be a through hole on the cross arm assembly 3 that is connected in an up-down manner. The diameter of the cross section of the through hole should be equal to or slightly larger than the diameter of the cross section of the guide ring, so that the cross arm assembly 3 can be firmly fixed on the main shaft assembly 1.

[0033] In some embodiments of the present application, the clamping portion 32 includes a first clamping portion 321 and a second clamping portion 322. The first clamping portion 321 and the second clamping portion 322 surround a sleeving cavity 323. One end of the first clamping portion 321 and the second clamping portion 322 is fixed on the connecting portion 33. The first clamping portion 321 and the second clamping portion 322 are sleeved on the main shaft assembly 1 and the guide ring 2 and then clamped together.

[0034] Specifically, the clamping portion 32 is divided into two parts, that is, the first clamping portion 321 and the second clamping portion 322. One end of the first clamping portion 321 and the second clamping portion 322 is connected to the connecting portion, and the other end can be separated from each other. When assembling, the other end is separated from each other, the main shaft assembly 1 and the guide ring 2 are placed in the sleeving cavity 323, and the other end of the first clamping portion 321 and the second clamping portion 322 is clamped together. This can make the entire detachable cantilever wire passing device fixed firmly and not easily shake. Of course, the clamping portion 32 can also be integrally formed, but in order to facilitate disassembly, a separate design is listed, which can more simply achieve installation.

[0035] In some embodiments of the present application, the main shaft assembly 1 further comprises at least two limiters 12 fixed on the main shaft rod 11, and the longitudinal distance between the limiters 12 is greater than or equal to the longitudinal length of the clamping portion 32.

[0036] Specifically, the limiters 12 are arranged on the main shaft rod 11, and the limiters 12 also serve to fix the cross arm assembly 3. More specifically, the limiters 12 limit the clamping portion 32 from moving up and down and shaking. Therefore, the upper and lower ends of the clamping portion of each cross arm assembly 3 abut against the limiters 12. The diameter of the cross section of the limiters 12 should be greater than the diameter of the cross section of the sleeve cavity 323 of the clamping portion 32, and the longitudinal distance between the two limiters 12 should be greater than or equal to the longitudinal length of the clamping portion 32. In this way, the cross arm assembly 3 can be fixed on the main shaft assembly 1 firmly, and the whole device is relatively stable.

[0037] In some embodiments of the present application, a plurality of copper sleeves 4 are sleeved on the main shaft assembly 1. The copper sleeve 4 comprises a copper sleeve body 41 and a flange plate 42. The diameter of the flange plate 42 is equal to or less than the diameter of the limiter 12, and the diameter of the copper sleeve body 41 is less than the diameter of the flange plate 42 and the diameter of the limiter 12.

[0038] Specifically, the copper sleeve 4 is a copper alloy casting, which has good wear resistance, corrosion resistance, heat conductivity and low friction coefficient. The copper sleeve 4 is installed at the sleeve joint of the main shaft assembly 1 and the cross arm assembly 3, which can lubricate the whole cantilever wire passing device, reduce the friction between the components, prolong the service life of the device, reduce the noise, and prevent the friction between the mechanical parts from increasing when the whole device stops rotating due to failure. In this case, the copper sleeve 4 can play a protective role to prevent the device from being stuck. More specifically, the diameter of the cross section of the flange plate 42 of the copper sleeve 4 is less than the diameter of the cross section of the limiter 12. The copper sleeve 4 is placed on the main shaft rod 11, and more specifically, the copper sleeve 4 is placed in the sleeve cavity 323 of the cross arm assembly 3. Therefore, the diameters of the cross sections of the copper sleeve body 41 and the flange plate 42 of the copper sleeve 4 are limited.

[0039] In some embodiments of the present application, the flange plate 42 abuts against the limiter 12, and the copper sleeve 4 abuts against the limiter 12.

[0040] Specifically, the two ends of the limiting piece 12 are respectively sleeved with the copper sleeve 4, wherein the flange plate 42 in the copper sleeve 4 abuts against the limiting piece 12, and the main body 41 of the copper sleeve is arranged towards the guide ring 2. Therefore, the overall device is that the main shaft rod 11 is provided with the limiting piece 12, the two ends of the limiting piece 12 are provided with the copper sleeve 4, the buckling part 32 of the horizontal arm assembly 3 is buckled between the two limiting pieces 12, the guide ring 2 can slide, and the first wire passing hole 112 is arranged between the limiting pieces 12. The arrangement of the two copper sleeves can make the overall device run more smoothly and can better guarantee safety and prolong the service life of the device.

[0041] In some embodiments of the present application, the guide ring 2 further comprises a groove part 22, the diameter of the groove part 22 is smaller than the diameter of the two ends of the guide ring 2, and the guide ring 2 is further provided with an opening 23 on the opposite side of the second wire passing hole 21, for sleeving the guide ring 2 on the main shaft rod 11.

[0042] Specifically, by arranging the groove part 22, the material cost of the guide ring 2 can be reduced, and the guide ring 2 can be better sleeved and fixed on the main shaft rod 11, so that the guide ring 2 cannot be moved at will. The guide ring 2 is provided with the opening 23, which facilitates the clamping of the guide ring 2 into the main shaft rod 11, and the diameter of the opening 23 should be smaller than the diameter of the main shaft rod 11.

[0043] In some embodiments of the present application, the guide ring 2 is an elastic member.

[0044] Specifically, the guide ring 2 is an object with a certain elasticity, which can be easily sleeved on the main shaft rod 11 by stretching and contracting.

[0045] In some embodiments of the present application, the guide ring 2 is sleeved on the main shaft rod 11, between the two limiting pieces 12, and between the two copper sleeves 4, and the diameter of the two ends of the guide ring 2 is smaller than the diameter of the limiting piece 12.

[0046] Specifically, the diameter of the two ends of the guide ring 2 is smaller than the diameter of the limiting piece 12, so that the moving position of the guide ring 2 is limited, and it can be limited between the two limiting pieces 12, more specifically, between the two copper sleeves 4.

[0047] The utility model also provides a kind of operating lamp, including the detachable cantilever wire passing device, spring arm and operating lamp body, it is characterized by: the detachable cantilever wire passing device one end connects ceiling, another end connects spring arm, by the spring arm connects operating lamp body, so that wire material can smoothly pass wire passing device, spring arm reaches operating lamp body.
