The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0017] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0018] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model is a quick-adjustment suspension mechanism for a shadowless lamp, comprising a shadowless lamp body 1 and a horizontal plate 2, both ends of the horizontal plate 2 are bent to form a connecting portion 10, and side plates 3 are provided on the outer sides of the connecting portion 10, and a positioning groove 15 is horizontally provided on the bottom surface of the horizontal plate 2, and a positioning block 16 is slidably installed in the positioning groove 15, and an adjustment seat 6 is installed at one end of the positioning block 16, and an adjustment port with an arc structure is provided on the adjustment seat 6, and an adjustment plate 12 with an arc structure is provided in the adjustment port, and one end of the adjustment plate 12 is fixedly connected to the shadowless lamp body 1, and a lifting and rotating mechanism for changing the height and direction of the shadowless lamp body 1 is installed above the cross bar.

[0020] In this embodiment, the lifting and rotating mechanism includes a cylinder 4, a sealed bearing, a fixing plate 5, a stud and a fixing seat 8. The sealed bearing is embedded in the middle of the horizontal plate 2, the piston rod of the cylinder 4 is installed in the inner ring of the sealed bearing, the fixing seat 8 is installed on the other end of the cylinder 4, and a plurality of fixing holes are arranged in an annular structure on the fixing seat 8. The fixing plate 5 is installed on the horizontal plate 2 and is arranged close to the cylinder 4. A first screw hole is provided on the horizontal plate 2, and a second screw hole 7 is provided at the piston rod of the cylinder 4 directly opposite to the first screw hole. The stud is threadedly connected to the first screw hole and the second screw hole 7, and a hand wheel 13 is installed at one end of the stud;

[0021] Among them, when it is necessary to be located on the left side of the operating position, the hand wheel can be rotated. The rotation of the hand wheel drives the stud to disengage the stud from the second screw hole. After the stud loses its fixation, the cross plate can rotate around the sealed bearing as the center until it rotates 180° to complete the turning of the shadowless lamp body. After confirmation, the stud is threadedly connected to the second screw hole again to fix the rotated cross plate.

[0022] In this embodiment, one end of the side panel 3 is bent inward to form a positioning portion 9, a slide groove 11 is vertically provided on the inner side surface of the side panel 3, and a slider 14 is installed on the outer side surface of the connecting portion 10. The slider 14 is slidably set in the slide groove 11 and is set in contact with the slide groove 11. The cross-sections of the slider 14 and the slide groove 11 are both trapezoidal structures, so that the slider can only move up and down along the slide groove, avoiding the slider from falling directly from the slide groove. After moving the slider upward, the slider can be moved out of the slide groove to complete the disassembly and assembly of the side panel.

[0023] In this embodiment, the cross-sections of the positioning block 16 and the positioning groove 15 are both set in a trapezoidal structure, and the positioning block 16 and the positioning groove 15 are set to be in contact with each other; the outer side surface of the adjustment plate 12 is set to be in contact with the inner side surface of the adjustment port, and the friction energy between the positioning block and the positioning groove can frictionally position the moved positioning block and the adjustment seat, and the friction energy between the slider and the slide groove can frictionally position the moved slider and the side plate.

[0024] When in use, the horizontal plate can be moved up and down through the extension and retraction of the cylinder. The movement of the horizontal plate drives the adjustment seat, the adjustment plate and the shadowless lamp body, so that the shadowless lamp body can be moved to a suitable height, and can also push the shadowless lamp body, so that the adjustment plate moves along the adjustment opening in a ring structure. The movement of the adjustment plate can make the shadowless lamp body lift up or press down to change the irradiation angle of the shadowless lamp body, and also fine-tune the height of the shadowless lamp body synchronously, and adjust the height of the shadowless lamp body again through the extension and retraction of the cylinder until it is in a precise state;

[0025] The cylinder can move the crossbar and the shadowless lamp body directly to one side of the surgical site and coordinate with the shadowless lamp body above to ensure sufficient illumination of the surgical site.

[0026] After the position is determined, the side panels can be moved downward until they are moved to both sides of the bed, and the device can be centrally hung above the bed through the side panels, thereby increasing stability.

[0027] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
