DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0036] like Figure 1 - Figure 7As shown, an auxiliary lighting device for oral examination provided by an embodiment of the present invention includes a vertical pole 101, and also includes: a horizontal rotating cross bar 102 rotatably connected to the upper end of the vertical pole 101 in the horizontal direction, a vertical rotating rod 103 for vertical rotation is hinged at the end of the horizontal rotating cross bar 102, and a rotating rod 104 is rotatably connected to the end of the vertical rotating rod 103 in the horizontal direction; a rotating block 105 for vertical rotation is hinged at the end of the rotating rod 104, and a mounting sleeve 106 is rotatably connected to the end of the rotating block 105, and a concave frame 107 is arranged on the mounting sleeve 106, and the concave frame 107 is rotated inside It is dynamically connected to a lighting box 108, on which a lighting lamp is installed; the horizontal rotating cross bar 102 is provided with a limited rotation component 2 and a pressure buffer component 4, the limited rotation component 2 is used to fix the vertical rotating rod 103 in a horizontal state, the rotating rod 104 is provided with a limited rotation component 23, the limited rotation component 23 is used to fix the rotating block 105 in a vertical state, the pressure buffer component 4 is used to hinder the rapid rotation of the vertical rotating rod 103, and the pressure buffer component 4 releases the fixing restriction of the rotating block 105 by the limited rotation component 23 through the downward rotation of the vertical rotating rod 103.

[0037] In the embodiment of the present invention, when using the lighting auxiliary equipment for oral examination, the vertical rotating rod 103 is rotated to a horizontal state, the rotation limit component 102 fixes the vertical rotating rod 103 in a horizontal state, and the rotation limit component 203 fixes the rotating block 105 in a vertical state. At this time, the concave frame 107 is dragged horizontally to drive the rotating rod 104 to rotate horizontally relative to the vertical rotating rod 103, and the vertical rotating rod 103 and the horizontal rotating cross bar 102 rotate horizontally relative to the vertical rod 101, so as to adjust the horizontal position of the concave frame 107 and the lighting lamp box 108, and then the lighting lamp box 108 can be adjusted to a position within a horizontal range. At this time, the lighting lamp box 108 is suspended, and when the horizontal position of the lighting lamp box 108 is adjusted, the objects under the lighting lamp box 108 will not affect the horizontal movement of the lighting lamp box 108, which is convenient for use during oral examination. The lighting lamp box 108 is rotated vertically to adjust the lighting angle of the lighting lamp box 108, which is further convenient for use during oral examination. When the lighting auxiliary equipment for oral examination is used or needs to be moved, the rotation limiting component 103 releases the horizontal fixed state of the vertical rotation rod 103, and the vertical rotation rod 103 rotates downward by its own weight. The pressure buffer component 4 hinders the rapid rotation of the vertical rotation rod 103, thereby preventing the vertical rotation rod 103 from rotating downward quickly, thereby protecting the lighting lamp box 108, and the pressure buffer component 4 releases the fixed restriction of the rotation limiting component 23 on the rotation block 105 by the vertical rotation of the vertical rotation rod 103 downward. The rotation block 105 maintains a vertical state by its own weight, thereby making the mounting sleeve 106, the concave frame 107 and the lighting lamp box 108 maintain a vertical state by their own weight, so that the vertical rotation rod 103, the rotating rod 104, the rotating block 105, the mounting sleeve 106, the concave frame 107 and the lighting lamp box 108 are in a vertical state, thereby reducing the space occupied by the lighting auxiliary equipment for oral examination, thereby facilitating the storage or movement of the lighting auxiliary equipment for oral examination.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, as a preferred embodiment of the present invention, the rotation limiting component 2 includes a guide groove 201 arranged on the horizontal rotating cross bar 102, and a limiting groove 204 arranged on one end of the vertical rotating rod 103 close to the rotation center, a limiting slider 202 is slidably connected in the guide groove 201, a compression spring 203 is fixed at one end of the limiting slider 202, and the compression spring 203 is arranged in the guide groove 201, the other end of the limiting slider 202 passes through the horizontal rotating cross bar 102 and cooperates with the limiting groove 204, a toggle block 206 is fixed at the upper end of the limiting slider 202, and an avoidance groove 205 for avoiding the movement of the toggle block 206 is arranged on the horizontal rotating cross bar 102.

[0039] In the embodiment of the present invention, when the vertical rotating rod 103 is in a horizontal state, under the guiding action of the guide groove 201, the compression spring 203 pushes the limiting slider 202, and the limiting slider 202 is inserted into the limiting groove 204. At this time, the horizontal rotating cross bar 102 and the vertical rotating rod 103 are fixedly connected; when it is necessary to move or store the lighting auxiliary equipment for oral examination, the toggle block 206 is pushed, and the toggle block 206 overcomes the elastic force of the compression spring 203 and drives the limiting slider 202 to move in the opposite direction, so that the limiting slider 202 is separated from the limiting groove 204, thereby releasing the fixed connection between the vertical rotating rod 103 and the horizontal rotating cross bar 102, and the vertical rotating rod 103 rotates downward by its own weight.

[0040] like Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, as a preferred embodiment of the present invention, the rotation limiting component 2 3 includes a guide groove 2 301 provided on the rotating rod 104, and a limiting countersunk hole 1 305 provided on the side wall of the rotating block 105, a guide block 302 is slidably connected in the guide groove 2 301, one end of the guide block 302 is connected to a compression spring 2 304, the compression spring 2 304 is provided in the guide groove 2 301, and a limiting protrusion 1 303 is fixed to the other end of the guide block 302, and the limiting protrusion 1 303 cooperates with the limiting countersunk hole 1 305.

[0041] In the embodiment of the present invention, when the lighting auxiliary device for oral examination is in working state, the rotating block 105 and the mounting sleeve 106 are in a vertical state with the rotating rod 104. Under the guiding action of the second guide groove 301, the second compression spring 304 pushes the guide block 302 to move, and the guide block 302 drives the limiting protrusion 1 303 to be inserted into the limiting countersunk hole 1 305, so that the rotating block 105 is fixedly connected with the rotating rod 104, so that the rotating block 105, the mounting sleeve 106, the concave frame 107 and the lighting lamp box 108 are stably in a vertical state to prevent the lighting lamp box 108 from shaking. When the rotating block 105 is in the vertical position, the guide block 302 overcomes the elastic force of the compression spring 304 and moves away from the rotating block 105. The guide block 302 drives the limiting protrusion 303 to disengage from the limiting countersunk hole 305, thereby releasing the fixed connection between the rotating block 105 and the rotating rod 104. At this time, when the rotating rod 104 rotates, the rotating block 105 will rotate relative to the rotating rod 104, and the rotating block 105, the mounting sleeve 106, the concave frame 107 and the lighting box 108 are in a vertical state due to their own weight until the vertical rotating rod 103, the rotating rod 104, the rotating block 105, the mounting sleeve 106, the concave frame 107 and the lighting box 108 are all in a vertical state.

[0042] like Figure 1 - Figure 7As shown, as a preferred embodiment of the present invention, the pressure buffer assembly 4 includes an adapter shaft 401 fixed on the vertical rotating rod 103 at the rotation center of the vertical rotating rod 103 and the horizontal rotating cross bar 102, a movable plate 404 is fixed on the adapter shaft 401, and a plurality of small holes 405 are arranged on the movable plate 404, a circular fixed shell 402 is fixed on the side wall of the horizontal rotating cross bar 102, a buffer is arranged in the circular fixed shell 402, and the buffer can be liquid such as hydraulic oil, a blocking plate 403 is fixed in the circular fixed shell 402, the movable plate 404 is slidably connected in the circular fixed shell 402, a pipe 406 is fixed on the circular fixed shell 402, a connecting pipe 407 is fixed at the end of the pipe 406, and the end of the connecting pipe 407 is connected to one end of the guide groove 2 301 close to the limiting protrusion 1 303, and sealing rings are installed on the side walls of the guide block 302 and the limiting protrusion 1 303.

[0043] In the embodiment of the present invention, when the vertical rotating rod 103 and the rotating rod 104 rotate downward, the vertical rotating rod 103 drives the transfer shaft 401 to rotate, and the transfer shaft 401 drives the movable plate 404 to rotate, so that the movable plate 404 turns to the blocking plate 403, and the gas or liquid between the blocking plate 403 and the movable plate 404 is compressed, and the gas or liquid between the blocking plate 403 and the movable plate 404 flows through the small hole 405, and the small hole 405 blocks the flow of gas or liquid, thereby blocking the movement of the movable plate 404, and then blocking the transfer shaft 401. 01 rotates, hindering the rotation of the vertical rotating rod 103, causing the vertical rotating rod 103 to slowly rotate downward, and the spatial pressure between the blocking plate 403 and the movable plate 404 increases, causing the gas or liquid in the circular fixed shell 402 to enter the guide groove 301 through the pipeline 406 and the connecting pipe 407, and the gas or liquid overcomes the elastic force of the compression spring 304 and pushes the guide block 302 to move, and the guide block 302 drives the limiting protrusion 303 to disengage from the limiting countersunk hole 305, at which time the fixed connection state between the rotating rod 104 and the rotating block 105 is released.

[0045] In the embodiment of the present invention, in the initial state, under the guiding action of the guide groove three 504, the compression spring three 506 pushes the limiting slider two 505, and the limiting slider two 505 is inserted into the limiting countersunk hole two 503, thereby limiting the upward and downward movement of the fixing rod 501, thereby fixing the height of the concave frame 107 and the lighting lamp box 108; when it is necessary to adjust the lighting height of the lighting lamp box 108, the pressing block one 510 is pressed, and the pressing block one 510 is retracted into the handle one 509, and the pressing block one 510 pulls the connecting rope one 508, and under the guiding action of the wire groove one 507, the connecting rope one 508 overcomes the elastic force of the compression spring three 506 and pulls the limiting slider two 505, so that The limiting slider 505 is disengaged from the limiting countersunk hole 503. At this time, the height of the fixed rod 501, the concave frame 107 and the lighting box 108 can be adjusted, thereby realizing the lighting height adjustment function of the lighting box 108; the weight of the C-shaped counterweight block 804 is the same as the sum of the weights of the fixed rod 501, the concave frame 107 and the lighting box 108.

[0048] like Figure 1 , Figure 8 , Fig.10 and Fig.11As shown, as a preferred embodiment of the present invention, a plurality of limiting countersunk holes 701 are arranged in an annular manner on the inner wall of the concave frame 107, an annular sliding groove 702 is arranged on the lighting lamp box 108, an annular sliding block 703 is slidably connected in the annular sliding groove 702, a plurality of limiting protrusions 704 are fixed in an annular manner on one end of the annular sliding block 703, the limiting protrusions 704 cooperate with the limiting countersunk holes 701, and a compression spring 705 is connected to the other end of the annular sliding block 703. A compression spring 4 705 is arranged in the annular sliding groove 702, and a handle 2 708 is fixed at the lower end of the lighting box 108, and a pressing block 2 709 is slidably connected to the handle 2 708. A wire groove 2 706 is arranged on the lighting box 108 and the handle 2 708, and a connecting rope 2 707 is arranged in the wire groove 2 706, one end of the connecting rope 2 707 is connected to the side wall of the handle 2 708, and the other end of the connecting rope 2 707 is connected to one end of the annular sliding block 703 close to the compression spring 4 705.

[0049] In the embodiment of the present invention, the cross-sectional shape of the annular sliding groove 702 is a regular octagon. In the initial state, under the guiding action of the annular sliding groove 702, the compression spring 4 705 pushes the annular sliding block 703, and the annular sliding block 703 drives the limiting protrusion 2 704 to be inserted into the limiting countersunk hole 3 701. At this time, the concave frame 107 is fixedly connected to the lighting box 108, and the lighting angle of the lighting box 108 is fixed; when adjusting the lighting angle of the lighting box 108, the pressing block 2 709 is pressed, and the pressing block 2 709 is pressed. 09 is retracted into the handle 2 708, the pressing block 2 709 pulls the connecting rope 2 707, and under the guiding action of the wire groove 2 706, the connecting rope 2 707 overcomes the elastic force of the compression spring 4 705 and pulls the annular sliding block 703 away from the inner wall of the concave frame 107, and the annular sliding block 703 drives the limiting protrusion 2 704 to disengage from the limiting countersunk hole 3 701. At this time, the lighting box 108 can be rotated relative to the concave frame 107, and the lighting angle of the lighting box 108 can be adjusted by rotating the lighting box 108 vertically.

[0050] The above embodiment of the present invention provides a lighting auxiliary device for oral examination. When the lighting auxiliary device for oral examination is used, the vertical rotating rod 103 is rotated to a horizontal state. Under the guiding action of the guide groove 201, the compression spring 203 pushes the limiting slider 202, and the limiting slider 202 is inserted into the limiting groove 204. At this time, the horizontal rotating cross bar 102 and the vertical rotating rod 103 are fixedly connected, and the fixed vertical rotating rod 103 is fixed in a horizontal state. The rotating block 105 and the mounting sleeve 106 are in a vertical state with the rotating rod 104. Under the guiding action of the guide groove 201, the compression spring 204 pushes the guide block 302 to move, and the guide block 302 drives the limiting protrusion 303 to be inserted into the limiting countersunk hole 305, thereby making the rotating cross bar 102 and the vertical rotating rod 103 fixedly connected. The moving block 105 is fixedly connected to the rotating rod 104, so that the rotating block 105, the installation sleeve 106, the concave frame 107 and the lighting box 108 are stably in a vertical state to prevent the lighting box 108 from shaking. At this time, dragging the concave frame 107 horizontally can drive the rotating rod 104 to rotate horizontally relative to the vertical rotating rod 103, and the vertical rotating rod 103 and the horizontal rotating cross bar 102 rotate horizontally relative to the vertical rod 101, so as to adjust the horizontal position of the concave frame 107 and the lighting box 108, so that the lighting box 108 can be adjusted to a position within a horizontal range. At this time, the lighting box 108 is suspended, and when the horizontal position of the lighting box 108 is adjusted, the objects below the lighting box 108 will not affect the horizontal movement of the lighting box 108. The lighting box 108 is vertically rotated to adjust the lighting angle of the lighting box 108, which is further convenient for use during oral examinations. When the lighting auxiliary equipment for oral examinations is not in use or needs to be moved, the toggle block 206 is pushed, and the toggle block 206 overcomes the elastic force of the compression spring 203 and drives the limiting slider 202 to move in the opposite direction, so that the limiting slider 202 is separated from the limiting groove 204, thereby releasing the fixed connection between the vertical rotating rod 103 and the horizontal rotating cross bar 102, and the vertical rotating rod 103 rotates downward by its own weight. When the vertical rotating rod 103 and the rotating rod 104 rotate downward, the vertical rotating rod 103 drives the transfer shaft 401 to rotate, and the transfer shaft 401 drives The movable plate 404 rotates, thereby causing the movable plate 404 to turn to the blocking plate 403, and the gas or liquid between the blocking plate 403 and the movable plate 404 is compressed, and the gas or liquid between the blocking plate 403 and the movable plate 404 flows through the small hole 405. The small hole 405 hinders the flow of gas or liquid, thereby hindering the movement of the movable plate 404, and then hindering the rotation of the adapter shaft 401, hindering the rotation of the vertical rotating rod 103, causing the vertical rotating rod 103 to slowly rotate downward, and the spatial pressure between the blocking plate 403 and the movable plate 404 increases, so that the gas or liquid in the circular fixed shell 402 enters the guide groove 301 through the pipeline 406 and the connecting pipe 407, and the gas or liquid overcomes the elastic force of the compression spring 304 and pushes the guide block 302 to move.The guide block 302 drives the limiting protrusion 303 to disengage from the limiting countersunk hole 305. At this time, the fixed connection between the rotating rod 104 and the rotating block 105 is released, and the rotating block 105 maintains a vertical state by its own weight, thereby keeping the mounting sleeve 106, the concave frame 107 and the lighting lamp box 108 in a vertical state by their own weight, so that the vertical rotating rod 103, the rotating rod 104, the rotating block 105, the mounting sleeve 106, the concave frame 107 and the lighting lamp box 108 are in a vertical state, thereby reducing the space occupied by the lighting auxiliary equipment for oral examination, thereby facilitating the storage or movement of the lighting auxiliary equipment for oral examination.
