Detailed Description

The invention is further described with reference to the accompanying drawings and specific embodiments.

In this embodiment, the operating lamp of illumination angularly adjustable includes: a surgical lighthead housing 100, a first lighthead 200, six second lightheads 300, six connections 400, a handle 500, and a bracket 600.

The first cap 200 includes: a first lamp head housing 210 and a plurality of first illumination lamps 220. In this embodiment, the first cap housing 210 has a circular shape. The handle 500 is arranged at the center of the first lamp holder shell 210, and the circumference of the handle 500 is provided with straight knurling for convenient operation. The first illuminating lamp 220 is disposed in a plurality of layers around the first lamp holder housing 210, and the first illuminating lamp 220 is centered around the handle 500.

Each of the second bases 300 includes: a second head housing 310 and twelve second illumination lamps 320. In this embodiment, the second cap housing 310 is fan-shaped, and the circumference is uniformly distributed on the circumference of the first cap 200. The second illumination lamp 320 is fixed in the second lamp head housing 310.

It should be noted that the present invention may not need to provide the first lamp cap 200, and only have the second lamp cap 300 to achieve the technical effects of the present invention.

The surgical lighthousing 100 is rotatably coupled to the support 600, although the support 600 may have other components, such as various adjustment rods and hanger bars. The first lamp head housing 210 is secured to the surgical lamp housing 100.

As shown in fig. 1 and 2 (the block diagram is not drawn to scale for details), one end of each rotating shaft 400 is rotatably connected to a circumferential location of the surgical lighthousing 100, i.e., through a corresponding aperture in the surgical lighthousing 100. The other end of each rotating shaft 400 is rotatably connected to the surgical lamp housing 100 near the center. The rotating shafts 400 in this embodiment are also circumferentially uniformly distributed. The rotation shaft 400 has rotation bearings 410 at both ends thereof, respectively, so that the rotation is more stable and smooth.

In this embodiment, each of the rotation shafts 400 has one driving motor 700, which can be individually adjusted in angle of each of the second lamp caps 300. The drive motor 700 is secured within the surgical light housing 100. An output shaft 710 of the driving motor 700 is fixedly connected to the rotary shaft 400 to drive the rotary shaft 400 to rotate. In this embodiment, the output shaft 710 of the driving motor 700 has at least one positioning key on its circumference. The right end of the rotary shaft 400 has a center hole which is fitted with an output shaft 710 of the driving motor 700. The central hole is sleeved on the output shaft 710 of the driving motor 700 to realize the fixed connection between the driving motor 700 and the output shaft 710, so that the output shaft 710 of the driving motor 700 drives the rotating shaft 400 to rotate. In this embodiment, the driving motor 700 is a stepping motor, and the angle can be accurately controlled.

Of course, only one driving motor 700 may be used to control the rotation of all the rotating shafts 400, and thus the arrangement requires the disposition of a transmission assembly. The driving motor 700 is connected to each of the rotating shafts 400 through a driving assembly, and simultaneously drives each of the first moving gears, at which time the angle of each of the second lightheads 300 is synchronously adjusted.

The second cap housing 310 has a rotation hole thereon. The rotating hole is in transition fit with the rotating shaft. The rotation holes of the second lamp holder case 340 are sleeved on the rotation shaft 400 in a one-to-one correspondence, and the rotation shaft 400 drives the second lamp holder case 310 to rotate. The transition fit is a fit which may have a gap or an interference, a tolerance zone of the hole and a tolerance zone of the shaft are overlapped, and the transition fit is mainly used for centering connection between the hole and the shaft. That is, the second cap housing 310 is not completely fixed to the rotation shaft, and in order to prevent the second cap housing 310 from not rotating with the rotation shaft 400 at unnecessary times, a cap screw 311 is provided on a sidewall of the second cap housing 310. The head screw 311 penetrates the second cap housing 310 to abut on the circumference of the rotation shaft 400.

Of course, if the angle of the second lamp cap 300 is required to be manually adjusted, the head stop screw 311 may be loosened to rotate the angle of the second lamp cap housing 310. In addition, the position of the second cap case 310 on the rotation shaft 400 can be moved to move closer to the first cap 200 or move away from the first cap 200, so that the second cap 300 can be adjusted more largely.

It should be noted that the relational terms in this document are only for the drawings in the present embodiment, so as to facilitate the description of the relative positional relationship; from different angles, the relative position relationship changes, and does not play a complete limiting role. The above specific embodiments have described only the first important features and innovative points of the solution. It will be appreciated by those skilled in the art that the present solution is not limited by the embodiments described above. Without departing from the spirit and scope of the invention, there are numerous variations and modifications that fall within the scope of the claims. The scope of the present solution is defined by the appended claims and equivalents thereof.
