Description

Technical Field

[0001] The utility model relates to the technical field of surgical lamps, in particular to a lamp upper hanging arm with a stable connection. Background Art

[0002] Surgical lights, also known as surgical lighting or surgical lamps, are lights with special functions that are primarily used in hospital operating rooms and outpatient surgical centers, but can also be used in other locations within a facility, such as emergency rooms, delivery rooms, examination rooms, and anywhere surgery is done. The main feature of a surgical light is to provide safe, bright surgical lighting, ensuring that doctors can clearly see the patient's surgical site during surgery for optimal visualization.

[0003] The applicant has searched the existing surgical lamps with hanging arms, and the hanging arms are all installed by a small number of screws. Since the lamp body of the surgical lamp is large, the screws are easy to loosen after long-term use, which will reduce safety. A surgical lamp disclosed in Chinese patent number CN205606413U includes a top plate, a crossbar, a vertical rod and a lamp holder. A large sleeve and a small sleeve are respectively provided at both ends of the crossbar. The crossbar is movably connected to the top plate through the large sleeve, and the crossbar is movably connected to the vertical rod through the small sleeve. A battery box is provided below the vertical rod, and a connecting piece is provided below the battery box. A first ring tube is installed at the front end of the connecting piece, and a rotating shaft is provided on both sides of the lamp holder. The first ring tube is fixedly connected to the rotating shaft, and a second ring tube is also installed at the front end of the rotating shaft. A light bulb is provided below the lamp holder. The surgical lamp has good lighting effect, is easy to adjust, and can continue to be used during power outages.

[0004] However, the applicant discovered that adding a large number of auxiliary mechanisms to the surgical light to enhance its performance would greatly increase the weight of the lamp body. After long-term use, the screws would loosen and the stability would decrease, which could easily lead to accidents. In addition, replacing the surgical light requires disassembling the connector connected to the ceiling, which is time-consuming and labor-intensive, and can easily damage the ceiling and create cracks, resulting in a decrease in the stability of the installed surgical light.

[0005] Therefore, in view of the above problems, it is necessary for the applicant to design a hanging arm with a stable connection to the lamp to solve the problem. Utility Model Content

[0027] Through the above structural design, the fixing screws 15 facilitate the firm connection between the steel plate 14 and the external ceiling, and the installing screws 16 facilitate the connection between the stabilizing mechanism 2 and the steel plate 14. At the same time, the stabilizing mechanism 2 facilitates pushing the suction cup 17 to tightly adsorb the steel plate 14, thereby improving the stability of the surgical lamp during use.

[0028] The stabilizing mechanism 2 includes a shell 21, and a guide rail 22 is fixedly arranged on the inner bottom surface of the shell 21, and two linkage mechanisms 3 are slidably arranged between the opposite surfaces of the guide rail 22, and the two linkage mechanisms 3 are identical, and a movable column 23 is arranged on the top surface of the two linkage mechanisms 3, and the end of the movable column 23 away from the linkage mechanism 3 slides through the top surface of the shell 21 and is fixedly connected to the bottom surface of the suction cup 17.

[0029] Through the above structural design, when the mounting screw 16 rotates, the linkage mechanism 3 will be pushed to move in a directional manner along the guide rail 22. The movement of the linkage mechanism 3 facilitates the movement of the movable column 23. The movement of the movable column 23 facilitates the suction cup 17 to be tightly adsorbed on the steel plate 14, thereby improving the stability of the surgical lamp during use.

[0030] The linkage mechanism 3 includes a slider 31, and the slider 31 is adapted to the guide rail 22, a linkage block 32 is fixedly provided on the top surface of the slider 31, and a connecting rod 33 is fixedly provided on the outer surface of one side of the linkage block 32, a moving block 34 is fixedly provided on the end of the connecting rod 33 away from the linkage block 32, and the bottom surface of the moving block 34 is fixedly connected to the top surface of the slider 31, a first inclined surface 35 is provided on the outer surface of one side of the linkage block 32, and the first inclined surface 35 is adapted to the movable column 23, and a second inclined surface 36 is provided on the outer surface of one side of the moving block 34, and the second inclined surface 36 is adapted to the mounting screw 16.

The spring elastic force pulls the linkage mechanism 3 to prevent the linkage mechanism 3 from sliding randomly, thereby protecting the linkage mechanism 3 from stable operation.

[0034] Working principle: when using this kind of lamp arm with stable connection, when installing the surgical light, the steel plate 14 is firmly installed by the fixing screws 15. After the steel plate 14 is installed, the installation screws 16 are rotated by external force. The installation screws 16 will push the moving block 34 to move through the second inclined surface 36. The movement of the moving block 34 is convenient for driving the connecting rod 33 to move. The movement of the connecting rod 33 is convenient for driving the linkage block 32 to move. The linkage block 32 moves through the first inclined surface 35 to facilitate the movement of the movable column 23. The movement of the movable column 23 is convenient for driving the suction cup 17 to be tightly adsorbed on the steel plate 14, thereby improving the stability of the surgical light during use. When the surgical light needs to be replaced, the installation screws 16 are removed. After the installation screws 16 are removed, the housing 21 is moved in the horizontal direction to facilitate the removal of the suction cup 17 away from the steel plate 14, thereby facilitating the removal of the surgical light under the condition of removing a small number of screws and without removing the steel plate 14, thereby improving safety and working efficiency.
