Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a foldable rotating arm mechanism. Background Art

[0002] Shadowless lamps are used to illuminate the surgical site to best observe small, low-contrast objects at different depths in the incision and body cavity. Since the operator's head, hands and instruments may cause interfering shadows on the surgical site, the shadowless lamp should be designed to eliminate shadows as much as possible and minimize color distortion. In addition, the shadowless lamp must be able to work continuously for a long time without emitting excessive heat, because overheating will make the operator uncomfortable and dry the tissue in the surgical area. In the prior art, the shadowless lamp adjusts the position of the shadowless lamp by adjusting the rotating arm, but the existing shadowless lamp base arm is directly connected to the hanging tube, and then connected to the rotating balance arm, resulting in the shadowless lamp's small range of movement being restricted, resulting in poor use. Therefore, a foldable rotating arm mechanism is urgently needed to solve the above problems. Utility Model Content

[0003] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a foldable rotating arm mechanism.

[0004] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0005] A foldable rotating arm mechanism comprises a suspension mounting seat, a suspension frame is mounted on the lower side of the suspension mounting seat, two groups of rotating arm assemblies are mounted on the suspension frame, and the other sides of the two groups of rotating arm assemblies are connected to a rotating curved frame;

[0006] The rotating boom assembly includes a rotating sleeve arranged on a suspension mounting seat, one side of the rotating sleeve is fixedly connected to an inner arm, a pin is installed on the outer side of the inner arm, an outer arm is hinged to the outer side of the inner arm through the pin, and a hanging tube is fixedly installed on the outer side of the outer arm.

[0007] It is further defined that the other side of the two groups of rotating curved frames is equipped with a parent-child lamp holder. Such a structural design is convenient for installing the parent-child shadowless lamp for use.

[0008] It is further defined that the rotating curved frame includes a first rotating curved rod connected to the hanging tube, the other side of the first rotating curved rod is rotatably connected to a second rotating curved rod, the other side of the second rotating curved rod is rotatably connected to a third rotating curved rod, and the third rotating curved rod is rotatably connected to the shadowless lamp holder. Such a structural design facilitates adjustment and control of the parent-child lamp holder.

[0009] It is further defined that a vertical tube is provided on the upper side of the first rotating curved rod, and the vertical tube is clamped in the hanging tube through a clamping spring. Such a structural design is convenient for installing the rotating curved frame.

[0010] The beneficial effects of the utility model are as follows: the utility model arranges a rotating boom assembly, which is composed of a pin shaft, an inner arm and an outer arm. The inner arm and the outer arm are connected by a pin shaft, so that no large action adjustment is required for moving the lamp in a small range, thereby increasing the small range rotation radius and improving the use effect.

[0018] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1-2 As shown, a foldable rotating arm mechanism of the utility model, a hanging frame 2 is installed on the lower side of the hanging mounting seat 1, two sets of rotating hanging arm assemblies 3 are installed on the hanging frame 2, and the other sides of the two sets of rotating hanging arm assemblies 3 are connected to a rotating curved frame 4;

[0020] The rotating boom assembly 3 includes a rotating sleeve 301 arranged on the suspension mounting seat 1, an inner arm 302 is fixedly connected to one side of the rotating sleeve 301, a pin shaft 303 is installed on the outer side of the inner arm 302, an outer arm 304 is hinged to the outer side of the inner arm 302 through the pin shaft 303, and a hanging tube 305 is fixedly installed on the outer side of the outer arm 304.

[0021] Preferably, a mother-and-child lamp holder is installed on the other side of the two sets of rotating curved frames 4. Such a structural design is convenient for installing the mother-and-child shadowless lamp for use. In fact, other structural shapes of the lamp holder can also be considered according to specific circumstances.

[0022] Preferably, the rotating curved frame 4 includes a first rotating curved rod 401 connected to the hanging tube 305, the other side of the first rotating curved rod 401 is rotatably connected to the second rotating curved rod 402, the other side of the second rotating curved rod 402 is rotatably connected to the third rotating curved rod 403, and the third rotating curved rod 403 is rotatably connected to the shadowless lamp holder. Such a structural design facilitates the adjustment and control of the parent-child lamp holder. In fact, other structural shapes of the rotating curved frame 4 can also be considered according to specific circumstances.

[0023] Preferably, a vertical tube 404 is provided on the upper side of the first rotating curved rod 401, and the vertical tube 404 is clamped in the drooping tube 305 through a clamping spring. Such a structural design is convenient for installing the rotating curved frame 4.

During use, when the mother-and-child shadowless lamp needs to be rotated in a small range, the rotating curved frame 4 is installed to drive the drooping tube 305, and the drooping tube 305 drives the outer arm 304, so that the outer arm 304 can rotate around the connection center with the inner arm 302 and the pin shaft 303, so that the small range of lamp movement does not require large-scale adjustment, thereby preventing the small range of movement of the mother-and-child shadowless lamp from being restricted.

[0025] Among them, in this embodiment, the mother-and-child shadowless lamp can also be replaced with a double-head shadowless lamp for use, which can also achieve the goal of moving the lamp in a small range without large-scale adjustment.
