DETAILED DESCRIPTION

[0029] To deepen the understanding of the present utility model, the present utility model will be further described in combination with the embodiment and the drawings. The present utility model can be implemented in the following ways:

[0030] Referring to Figures 1-7 , a dental operating lamp ceiling guide rail, comprising a guide rail 1 mounted on the ceiling and an endoscope display 2 and a work light 3 in sliding connection with the guide rail 1. In this embodiment, the endoscope display 2 and the work light 3 are in sliding connection with the guide rail 1 arranged on the ceiling, so that they do not need to be installed on the side box or the side of the dental chair, thereby not hindering the movement of the doctor during the operation process, and the user experience effect is good.

[0031] The endoscope display 2 and the working lamp 3 are both slidably connected with the guide rail 1 through the movable arm 4 arranged below the guide rail 1. The movable arm 4 comprises a sliding seat 41, a straight pipe 42, a U-shaped pipe 43 and a flexible lifting swing arm 44 connected in sequence, and the sliding seat 41 is slidably connected with the guide rail 1. Since the guide rail 1 has a large slidable stroke, and the movable arm 4 is provided with the flexible lifting swing arm 44, the lifting range and the rotation angle are large, so that the application range is larger and more flexible. Two groups of slide groove structures 11 for slidably connecting the two movable arms 4 are arranged on the guide rail 1. The two groups of slide groove structures 11 in the embodiment are symmetrically designed, one group is used for installing the endoscope display 2, and the other group is used for installing the working lamp 3. The slide groove structure 11 comprises an inner slide groove 111 and an outer slide groove 112 with openings facing downward, and the top of the sliding seat 41 is provided with an inner side pulley set 411 and an outer side pulley set 412 slidably arranged in the inner slide groove 111 and the outer slide groove 112 respectively. The inner side pulley set 411 and the outer side pulley set 412 both comprise a plurality of longitudinal pulleys 413, and the outer side pulley set 412 is further provided with a transverse pulley 414 between two adjacent longitudinal pulleys 413. This design can make the sliding seat 41 more balanced and stable during sliding along the slide groove structure 11. In addition,

[0032] In addition, the inner slide groove 111 and the outer slide groove 112 are provided with a drag chain groove 113 for moving a drag chain. The drag chain groove 113 is used for installing an electric wire drag chain electrically connected with the endoscope display 2 and the working lamp 3, so as to better cooperate with the endoscope display 2 and the working lamp 3 to slide.

[0033] In order to realize the lifting and rotation of the endoscope display 2 and the working lamp 3, one end of the flexible lifting swing arm 44 is movably connected with the U-shaped pipe 43, and the other end is movably connected with the endoscope display 2 or the working lamp 3. The flexible lifting swing arm 44 can make the endoscope display 2 and the working lamp 3 hover at any position. Specifically, referring to Figure 5The elastic lifting rotating arm 44 is internally provided with an adjusting connecting rod 441, one end of the adjusting connecting rod 441 is hingedly connected with a connecting arm head 442 which is rotationally connected with the U-shaped tube 43, and the other end is hingedly connected with a small connecting arm head 443 which is connected with the endoscope display 2 or the working lamp 3. The rotationally connected part of the connecting arm head 442 and the U-shaped tube 43 is connected by a bearing, which can improve the load bearing capacity of the movable arm. When the elastic lifting rotating arm 44 rotates horizontally, the connecting arm head 442 can be synchronously rotated in the U-shaped tube 43, so as to realize the horizontal rotation of the elastic lifting rotating arm 44. The outer shell 444 of the elastic lifting rotating arm 44 is provided with a through hole for the upper end of the connecting arm head 442 to pass through, the outer shell 444 of the elastic lifting rotating arm 44 is hingedly connected with the connecting arm head 442 by a bolt, and the adjusting connecting rod 441 inside is hingedly connected with the connecting arm head 442, so that the elastic lifting rotating arm 44 can longitudinally swing and rotate, thereby driving the endoscope display 2 and the working lamp 3 to lift and lower. During the lifting and lowering of the endoscope display 2 and the working lamp 3, the connecting arm head 442 and the small connecting arm head 443 always maintain a vertical state. The adjusting connecting rod 441 is sleeved with a spring 445 and a limiting component 446 which limits the maximum stroke of the spring 445. The limiting component 446 includes a limiting sleeve 4461 which is sleeved on the adjusting connecting rod 441 and a pull rod 4462 which is arranged above the spring 445, one end of the pull rod 4462 is connected with the connecting arm head 442, and the other end is connected with the limiting sleeve 4461. This design can make the elastic lifting rotating arm 44 balance the gravity through mechanical adjustment, so that the endoscope display 2 and the working lamp 3 can hover at any position in the lifting direction.

[0034] In order to realize the rotation of the endoscope display 2 in the horizontal and vertical directions, with reference to Figure 6 The endoscope display 2 is movably connected with the elastic lifting rotating arm 44 through a rotating assembly one 21. The rotating assembly one 21 includes a connecting rod 211 connected with the elastic lifting rotating arm 44, a rotating seat 212 rotationally connected with the lower end of the connecting rod 211, a rotating piece 213 hingedly connected with the rotating seat 212, and fixed connecting pieces 214 fixedly connected with the rotating piece 213 and the endoscope display 2 on both sides. This design can make the endoscope display 2 rotate around the connecting rod 211 through the rotation of the rotating seat 212. In addition, the rotating piece 213 is hingedly connected with the rotating seat 212 through a rotating shaft 215 and a damping copper sleeve arranged on the rotating shaft 215, so that the endoscope display 2 can rotate around the rotating shaft 215, and the endoscope display 2 can hover at any vertical rotation angle.

[0035] In addition, the connecting part of the rotating assembly one 21 and the endoscope display 2 is provided with a handle 22 which is convenient for pulling up and down the endoscope display 2. When it is necessary to adjust the vertical height of the endoscope display 2, it is only necessary to pull the handle 22 up and down to drive the endoscope display 2 to lift and lower.

[0036] In order to realize the multi-angle rotation of the working lamp 3, with reference to Figure 7 , the working lamp 3 is movably connected with the elastic lifting rotating arm 44 through the rotating assembly two 31. The rotating assembly two 31 comprises a switch back seat 311 for controlling the operation of the working lamp 3 and a rotating handle 312 rotatably connected with the switch back seat 311. The bottom of the switch back seat 311 is provided with a switch handle 3111, which facilitates the doctor to turn on or turn off the working lamp 3. The rotating handle 312 is rotatably connected with the switch back seat 311 through a rotating sleeve 3121, so that the rotating handle 312 can rotate a certain angle around the axis of the rotating sleeve 3121, thereby driving the working lamp 3 to rotate synchronously. The working lamp 3 is rotatably connected with the rotating handle 312, so that the working lamp 3 can rotate around the hinge of the rotating handle 312, thereby realizing the multi-angle rotation of the working lamp 3. The two sides of the working lamp 3 are provided with handles 32 for facilitating the rotation or upward and downward pulling of the working lamp 3, thereby improving the convenience of the doctor in use.

[0037] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
