[0041] To address the problems existing in the background art, this application proposes the following technical solution: a light source structure for an ophthalmic testing device, including a base 100, a sleeve 200 fixedly connected to the base 100, a sleeve rod 2001 slidably connected inside the sleeve 200, a positioning bolt 2002 threadedly connected to the sleeve 200, a positioning screw for abutting and fixing the sleeve rod 2001, and a folding adjustment component provided on the outside of the sleeve rod 2001.

[0042] To facilitate movement, casters 1001 are fixedly connected to all four sides of the bottom of the base 100, and a fixed frame 1002 is fixedly connected to the base 100 for placing tools.

[0043] Specifically, the folding adjustment assembly includes a first adjusting arm 300 and a second adjusting arm 3003. A first mounting base 2003 is fixedly connected to the top of the sleeve rod 2001. A first universal ball joint 2004 is rotatably connected to the first mounting base 2003. The first universal ball joint 2004 assists the first adjusting arm 300 in angle adjustment, thus the first adjusting arm 300 is fixedly connected to the first universal ball joint 2004. A second mounting base 3001 is fixedly connected to one end of the first adjusting arm 300. A second universal ball joint 3002 is rotatably connected to the second mounting base 3001. The second adjusting arm 3003 is fixedly connected to the second universal ball joint 3002. The second universal ball joint 3002 is used for angle adjustment of the second adjusting arm 3003. A third mounting base 3005 is fixedly connected to one end of the second adjusting arm 3003. A third universal ball joint 3004 is rotatably connected to the third mounting base 3005. A connecting rod 3006 is fixedly connected to the outside of the third universal ball joint 3004. One end of the connecting rod 3006 is fixedly connected to the lamp holder 400. The third universal ball joint 3004 is used to assist the lamp holder 400 in angle adjustment. In addition, fastening bolts are threaded into the first mounting base 2003, the second mounting base 3001, and the third mounting base 3005, all of which are used to abut and fix the universal ball joint.

[0044] In a further design, a lamp holder 400 is connected to one end of the folding adjustment component. Multiple lamp holders 400 are provided and are spliced ​​together. A lamp panel 500 is detachably connected to the bottom of the lamp holder 400, and a lighting component is provided at the bottom of the lamp panel 500.

[0045] Specifically, the lamp holder 400 has a first male connector 4001 and a first female connector 4002 on its outer sides respectively. The first male connector 4001 and the second male connector 4009 are connected to conduct electricity between the positive and negative poles. After the first male connector 4001 and the first female connector 4002 are plugged in, they are used to supply power to the second male connector 4009 on the lamp holder 400, thus achieving electrical connection.

[0046] Additionally, a lifting plate 4008 is provided at the top of the lamp holder 400. A second male connector 4009 is fixedly connected to the bottom of the lifting plate 4008. The second male connector 4009 passes through and is slidably connected to the lamp holder 400. A second spring 40010 is connected between the lifting plate 4008 and the lamp holder 400. A sliding groove 4004 is provided at the top of the lamp holder 400. A slider 4005 is slidably connected in the sliding groove 4004. A first spring 4006 is connected between the slider 4005 and the sliding groove 4004. The top of the slider 4005 is fixedly connected to... There is a contact block 40012, one end of which is inclined. Both ends of the lifting plate 4008 are provided with inclined edges 40011. In the initial state, the contact block 40012 abuts against the bottom of the lifting plate 4008, and the second plug male 4009 is located inside the lamp holder 400. When the slider 4005 drives the contact block 40012 to slide away from the lifting plate 4008, the second plug male 4009 can be pushed downward by the elastic force of the second spring 40010. The electrical connection principle is existing technology.

[0047] To complement the above structure, a snap-fit ​​plate 5001 and a second plug-in female head 5002 are fixedly connected to the top of the lamp panel 500, and the lighting components are multiple lamp beads 5003 fixedly connected to the bottom of the lamp panel 500.

[0048] Among them, a rotating plate 4007 is rotatably connected to the top of the contact block 40012. The rotating plate 4007 has an L-shaped structure. Both ends of the lamp holder 400 are fixedly connected to the limiting plate 4003. The rotating plate 4007 is used to abut and fix the limiting plate 4003. When necessary, a slot can be set on the outside of the limiting plate 4003, and a snap-fit ​​block can be set on the outside of the limiting plate 4003. After clamping, the lamp holder 400 can be stabilized by snapping the snap-fit ​​block with the slot.

[0049] In a further design, multiple sets of limiting posts 40013 are fixedly connected to the lamp holder 400. The top of the limiting post 40013 is provided with a limiting hole 40014. Additionally, a splicing frame 600 is included, on which a fixing frame 6001 is fixedly connected. A limiting protrusion 6002 is fixedly connected to the bottom of the fixing frame 6001. The fixing frame 6001 has a through hole 6003. The bottom of the limiting protrusion 6002 and the inner surface of the limiting hole 40014... Each part is fixedly connected with a magnet. The magnet is used to achieve adsorption and fixation after the limiting protrusion 6002 is inserted into the limiting hole 40014. The splicing frame 600 passes through two adjacent limiting posts 40013. At the same time, the limiting protrusion 6002 is inserted into the limiting hole 40014 to achieve quick splicing and installation. The insertion of the first male plug 4001 and the first female plug 4002 realizes the power supply to the second male plug 4009 on the lamp holder 400.

[0050] To ensure that those skilled in the art can fully understand the technical solution, this embodiment is summarized as follows:

[0051] Depending on the required number of lamp holders 400, specifically, connect the first male connector 4001 and the first female connector 4002 of two adjacent lamp holders 400. Take the splicing frame 600 and pass it through two adjacent limiting posts 40013. Simultaneously, insert the limiting protrusion 6002 into the limiting hole 40014 to achieve rapid splicing and installation. (Refer to the attached document.) Figure 3-4 The connection of the first male connector 4001 and the first female connector 4002 enables power supply to the second male connector 4009 on the lamp holder 400.

[0052] Next, install the lamp panel 500 at the bottom of the lamp holder 400, slide the abutment block 40012 outward so that the abutment block 40012 no longer abuts the bottom of the lifting plate 4008. At this time, the slider 4005 stretches the first spring 4006, and under the push of the elastic force of the second spring 40010, the second plug male 4009 will be plugged into the second plug female 5002. Then rotate the rotating plate 4007 so that the rotating plate 4007 is locked onto the outside of the locking plate 5001. And through the pull of the first spring 4006, the lamp panel 500 can be firmly clamped under the lamp holder 400 by the rotating plate 4007.

[0053] During disassembly, simply rotate the rotating plate 4007 so that it no longer clamps against the snap-fit ​​plate 5001. Then remove the lamp plate 500. Under the elastic force of the first spring 4006, the contact block 40012 abuts against the bottom of the lifting plate 4008, lifting the lifting plate 4008 and allowing the second male connector 4009 to disengage from the second female connector 5002.

[0054] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings.
