[0029] Next, each embodiment of the present invention will be described in detail with reference to the reference append Figures 1 to 8 Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0030] A modular light source adjustment device, as shown in the append Figure 1 includes a support base 1. A slide block 3 is slidably arranged on the support base 1 in the left-right direction. A lifting seat 5 for installing a light source (not shown in the figure) is arranged on the slide block 3. The lifting seat 5 is used to install different light sources. By controlling the position of the slide block 3 in the left-right direction and the height of the lifting seat 5, the specific position of the light source can be controlled. This part is the prior art and will not be elaborated here.

[0031] As shown in the append Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, the slide block 3 is connected with a first reciprocating motion mechanism. Specifically, reference can be made to the A position in the append Figure 1 and the append Figure 2 shown. The first reciprocating motion mechanism includes a rotating shaft A 12. When the rotating shaft A 12 rotates unidirectionally, it drives the slide block 3 to perform reciprocating motion in the left-right direction. The lifting seat 5 is connected with a second reciprocating motion mechanism. Specifically, reference can be made to the B position in the append Figure 1 and the append Figure 3As shown in the figure, the second reciprocating motion mechanism includes a rotating shaft B13 and a telescopic tube A14 connected to the rotating shaft B13. Through the telescopic tube A14, it can adaptively expand and contract when the slider 3 moves in the left-right direction. When the rotating shaft B13 rotates unidirectionally, it drives the lifting seat 5 to make a reciprocating motion in the vertical direction.

[0032] It also includes a control mechanism for controlling the first reciprocating motion mechanism and the second reciprocating motion mechanism. For details, please refer to the appendix Figure 4 As shown in the figure, the control mechanism includes a gear A25 fixedly connected to the rotating shaft A12 and a gear B26 fixedly connected to the rotating shaft B13. An arc-shaped chute 24 is provided on one side of the gear A25 and the gear B26. A gear C27 is slidably and rotatably provided in the arc-shaped chute 24. The gear C27 can be meshed and connected with the gear A25 or the gear B26. The gear C27 is meshed and connected with a gear D20. It also includes a control handle 17 for controlling the rotation of the gear D20.

[0033] Working principle: When the gear D20 rotates clockwise, it drives the gear C27 to slide and engage with the gear B26. As the gear D20 continues to rotate clockwise, it drives the gear C27 to rotate counterclockwise, and then drives the gear B26 to rotate clockwise, and then drives the rotating shaft A12 to rotate, and then drives the first reciprocating motion mechanism to move, so as to adjust the left-right position of the slider 3 and realize the adjustment of the left-right position of the lifting seat 5; when the gear D20 rotates counterclockwise, it drives the gear C27 to slide and engage with the gear A25. As the gear D20 continues to rotate counterclockwise, it drives the gear C27 to rotate clockwise, and then drives the rotating shaft B13 to rotate, and then drives the second reciprocating motion mechanism to move, realizing the adjustment of the height of the lifting seat 5.

[0034] In specific use, the light source is installed on the lifting seat 5. By rotating the control handle 17 forward and backward by a certain angle in sequence, the position of the light source can be adjusted.

[0035] In the present invention, by controlling the rotation direction of the gear D20, the gear C27 is driven to be meshed and connected with the gear A25 or the gear B26, and the corresponding gear is driven to rotate, and then the corresponding reciprocating motion mechanism is driven to move; first, by controlling the rotation of the gear D20, the gear A25 can be driven to move, and then the first reciprocating motion mechanism is driven to move to adjust the left-right position of the slider 3. Subsequently, when the gear D20 rotates in the reverse direction, the gear B26 can be driven to move, and then the second reciprocating motion mechanism is driven to move to adjust the height of the lifting seat 5, and finally the position of the lifting seat 5 is adjusted; through the rotation of a single gear D20, the present invention can realize the adjustment of the position of the lifting seat 5 in two degrees of freedom directions, without the occurrence of misoperation, and the adjustment is more accurate; and since the present invention only needs to control the rotation of the gear D20, it is also more convenient to adjust and use, without the need to change the operation position, and it is also convenient to add a transmission mechanism outside the gear D20 to control the movement of the gear D20.

[0036] In addition, it should be noted that in the present invention, a certain damping can be set for the rotating shaft A12 and the rotating shaft B13, that is, when the gear C27 is not engaged and driven with the gear A25 and the gear B26, the rotating shaft A12 and the rotating shaft can be self-positioned, so as to prevent movement after adjusting the position of the lifting seat 5.

[0037] In addition, it should be noted that in the present invention, a certain damping should be set for the gear C27, so that when the gear D20 drives the gear C27 to move, the gear C27 first slides in the arc-shaped chute 24 until it slides to the end of the arc-shaped chute 24, and then the gear D20 drives the gear C27 to rotate.

[0038] In addition, it should be noted that in the present invention, a control motor can also be set at the control handle 17, and the control handle 17 is driven to rotate by the forward and reverse rotation of the control motor to achieve adjustment.

[0039] In addition, it should be noted that in the present invention, when the control handle 17 is adjusted to rotate unidirectionally, when the rotation angle is exceeded, since the light source makes a reciprocating motion, it is only necessary to continue rotating the control handle 17 to make the light source move to the position to be adjusted again.

[0040] As shown in the appendix Figure 1 、 Figure 4 In the present embodiment, the support seat 1 is in an inverted "T" shape, including a vertical plate and a horizontal plate. A horizontal chute 2 is provided at the top of the front side of the horizontal plate. The slider 3 is slidably arranged in the horizontal chute 2. A telescopic tube B4 is provided at the top of the slider 3 and is connected to the lifting seat 5 through the telescopic tube B4. The lifting seat 5 is moved left and right along with the slider 3 through the telescopic tube B4 and can be lifted. The rotating shaft A12 and the rotating shaft B13 rotatably pass through the vertical plate. The arc-shaped chute 24 is fixedly arranged on the right side of the vertical plate. The gear D20 is rotatably arranged on the right side of the vertical plate, that is, the entire control mechanism is arranged on the right side of the vertical plate.

[0041] As shown in the appendix Figure 1 、 Figure 2 、 Figure 3 In the present embodiment, the first reciprocating motion mechanism includes a frame A6 fixedly connected to the slider 3. The frame A6 is horizontally arranged. Card teeth are respectively provided on the front and rear sides inside the frame A6 and internally engage with a gear E8. The gear E8 is a semi-gear. A rotating shaft C7 is fixedly arranged vertically through the gear E8. The bottom of the rotating shaft C7 is rotatably connected to the support seat 1, and a gear F10 is provided at the top. The gear F10 is vertically meshed with a gear G11. The gear G11 is fixedly connected to the rotating shaft A12. Among them, the gear F10 and the gear G11 can be bevel gears to achieve vertical meshing connection.

[0042] Working principle: When the shaft A12 rotates, it drives the gear G11 to rotate, and then drives the gear H15 to rotate, and then drives the shaft C7 to rotate, and then drives the gear E8 to rotate, and then drives the frame A6 to reciprocate in the left and right directions, and then drives the slider 3 to reciprocate in the left and right directions, so that when one-way rotation is achieved, the slider 3 is driven to reciprocate in the left and right directions. At the same time, the telescopic tube A14 is adaptively telescoped. In addition, it should be noted that in this embodiment, a connecting rod 9 is also provided between the frame A6 and the slider 3.

[0043] As attached Figure 1 , Figure 3 As shown, in this embodiment, the lifting seat 5 is in an "L" shape, including a vertical plate and a horizontal plate. The horizontal plate is arranged at the bottom of the front side of the vertical plate, and the horizontal plate is connected to the telescopic tube B4. The second reciprocating motion mechanism includes a frame B16 fixedly connected to the vertical plate. The frame B16 is vertically arranged, and the front and rear sides of the frame B16 are respectively provided with latch teeth, and a gear H15 is meshedly connected inside. The gear H15 is rotatably arranged on the vertical plate, and the gear H15 is fixedly connected to the telescopic tube A14.

[0044] Working principle: When the rotating shaft B13 rotates, it drives the telescopic tube A14 to rotate, and then drives the gear H15 to rotate, and then drives the frame B16 to reciprocate in the vertical direction, so that when the rotating shaft B13 rotates unidirectionally, the lifting seat 5 reciprocates in the vertical direction.

[0045] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, in this example, the gear H15 is always meshed and connected with the frame B16, that is, the frame B16 always rotates and moves with the gear H15. In specific use, the gear D20 can be controlled to rotate counterclockwise first to adjust the front and rear position of the slider 3, and then adjust the position of the lifting seat 5 and the light source. After the adjustment is completed, the gear D20 is controlled to move clockwise. When the gear D20 moves clockwise, since the frame A6 is not subjected to force in the left and right directions, the frame A6 will not move in the left and right directions and can remain stable. That is, the position of the light source in the left and right directions is determined. As the gear D20 moves clockwise, the position of the lifting seat 5 and the light source in the vertical direction is adjusted. After the adjustment is completed, it is only necessary to ensure that the position of the gear D20 remains unchanged, that is, the height of the light source can be controlled to remain unchanged. Specifically, a certain limiting mechanism can be added to the gear D20, and finally the position of the light source can be adjusted in two degrees of freedom.

[0046] As attached Figure 1 , Figure 4As shown, in this factual example, the support base 1 is provided with a plate body 19, specifically located near the upper part on the right side of the vertical plate. A lead screw 18 is threaded through the plate body 19. The lead screw 18 is arranged in the vertical direction. The bottom end of the lead screw 18 is rotatably connected to a rack 22. The rack 22 is meshed with a gear I21. The gear I21 is coaxially connected to a gear D20. A limiting rod 23 is provided on the support base 1. The rack 22 is slidably connected to the limiting rod 23 in the vertical direction. A control handle 17 is arranged at one end of the lead screw 18 away from the rack 22.

[0047] Working principle: By driving the lead screw 18 to rotate through the control handle 17, the height of the lead screw 18 is changed, and then the gear I21 is driven to rotate, and then the gear D20 is driven to rotate. And after the control handle 17 rotates, the lead screw 18 moves downward under the action of gravity, increasing the friction between the lead screw 18 and the plate body 19, which can prevent the lead screw 18 from rotating automatically, playing an automatic limiting role and preventing self-displacement.

[0048] As shown in the attached Figure 1 、 Figure 8 figure, in this embodiment, a transparent cover body 29 is further included and arranged on the support base 1. A cover body 28 is provided on the transparent cover body 29. Specifically, the transparent cover body 29 can be made of glass material so that the light source can pass through the transparent cover body 29. The cover body 28 can be hingedly arranged. The transparent cover body 29 can play a role in protecting and dust-proofing the internal structure, protecting the internal structure, and can avoid accidental touch of the lifting seat 5 before and after adjustment, thus ensuring the accuracy after adjusting the light source. And the light source on the lifting seat 5 can be replaced through the cover body 28. In this embodiment, the transparent cover body 29 is detachably connected to the support base 1. The transparent cover body 29 is provided with a perforation. The lead screw 18 passes through the perforation and does not contact the transparent cover body 29. The control handle 17 is detachably connected to the lead screw 18. After the control handle 17 is removed, the transparent cover body 29 can be removed to check and replace the internal structure, etc.

[0049] As shown in the attached Figure 1 、 Figure 4 、 Figure 8 figure, in this embodiment, the support base 1 is provided with a fixing hole, specifically a threaded hole, through which the whole device can be fixed to ensure the stability of the device.
