Detailed Embodiments

[0021] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0022] Please refer to Figures 1 - 5 , wherein, Figure 1 Schematic diagram of the overall structure of the fundus camera operation trolley provided by the present utility model; Figure 2 Exploded view of the fundus camera operation trolley provided by the present utility model;

[0023] Figure 3 The exploded view of the support vehicle body provided by the present utility model; Figure 4 The schematic diagram of the reset device provided by the present utility model; Figure 5 The schematic diagram of the reset frame provided by the present utility model.

[0024] In the specific implementation process, such as Figures 1 - 5 shown, a fundus camera operation trolley includes a support vehicle body and an upper support plate 1 provided on the support vehicle body. Four clamping devices are provided at the upper end of the support vehicle body, and the support vehicle body is connected to the upper support plate 1 through the four clamping devices;

[0025] Among them, the fundus camera main body 2 is directly installed above the upper support plate 1;

[0026] The clamping device includes a clamping block 9 and a first spring 11. One end of the clamping block 9 extends into the movable groove provided on the support vehicle body. One end of the clamping block 9 close to the movable groove is fixedly connected to one end of the first spring 11. The end of the first spring 11 far from the clamping block 9 is fixedly connected to the inner side of one side of the movable groove. The end of the clamping block 9 far from the first spring 11 extends into the installation groove 15 provided inside the upper support plate 1. The edge of the end of the clamping block 9 close to the installation groove 15 is set to be arc-shaped, and the side of the clamping block 9 close to the installation groove 15 is inclined from the edge close to the installation groove 15 to the direction close to the first spring 11;

[0027] In the specific use process, when installing between the upper support plate 1 and the connecting column 7, only need to send the upper part of the connecting column 7 into the inside of the upper support plate 1. In this process, because the side of the clamping block 9 close to the installation groove 15 is inclined from the edge close to the installation groove 15 to the direction close to the first spring 11, when the clamping block 9 contacts the upper support plate 1, the upper support plate 1 squeezes the clamping block 9, so that the clamping block 9 is squeezed into the inside of the connecting column 7. During the movement of the clamping block 9, the first spring 11 will be compressed until the clamping block 9 moves to the position of the installation groove 15 provided inside the upper support plate 1, and then the driving force of the first spring 11 makes the clamping block 9 enter the inside of the upper support plate 1, completing the fixation between the upper support plate 1 and the connecting column 7. This structure is simpler than the traditional one that requires the upper support plate 1 to be placed upside down on the ground and requires multiple people to cooperate to turn over and carry the fixed lower support plate 6 and the connecting column 7. The overall structure is simple and the operation is more simple, making the overall installation process more convenient;

[0028] The supporting vehicle body includes a connecting column 7 and a lower support plate 6. The upper end of the connecting column 7 extends into a first engaging groove 12 provided inside the upper support plate 1, and one end of the connecting column 7 away from the first engaging groove 12 extends into a second engaging groove 16 provided on the lower support plate 6. Opposite ends of the connecting column 7 are also fixedly connected with mounting plates 4. The two mounting plates 4 are respectively connected to the connecting column 7 and the lower support plate 6 through a plurality of fixing bolts 5. A plurality of universal wheels 8 are also installed at the bottom end of the lower support plate 6;

[0029] A reset device for resetting the positions of the four engaging blocks 9 is further provided at the bottom end of the upper support plate 1. The reset device includes a reset frame 3, four connecting components, and four pushing components. The inner side wall of the reset frame 3 is movably connected to the outer side wall of the connecting column 7. The four pushing components are provided at the upper end of the reset frame 3, and the four pushing components are respectively used to reset the positions of the four engaging blocks 9. The reset frame 3 is connected to the bottom end of the upper support plate 1 through four connecting components. The pushing component includes a pushing block 14. The bottom end of the pushing block 14 is fixedly connected to the upper end of the reset frame 3. One side of the pushing block 14 is in contact with the side of the engaging block 9 away from the first spring 11. The connecting component includes a support column 10 and a second spring 13. One end of the support column 10 is fixedly connected to the upper end of the reset frame 3. The end of the support column 10 away from the reset frame 3 extends into a connecting hole provided at the bottom of the upper support plate 1. The end of the support column 10 close to the connecting hole is fixedly connected to one end of the second spring 13. The end of the second spring 13 away from the support column 10 is fixedly connected to one side inside the connecting hole;

[0030] In the specific use process, when it is necessary to separate the upper support plate 1 from the connecting column 7, the reset frame 3 can be pushed towards the upper support plate 1, so that the pushing block 14 can be sent into the upper support plate 1. In this process, since one side of the pushing block 14 is in contact with the side of the engaging block 9 away from the first spring 11, during the movement of the pushing block 14, the engaging block 9 will be continuously pushed into the connecting column 7. Eventually, the engaging block 9 will completely enter the connecting column 7. At this time, the upper support plate 1 and the connecting column 7 can be separated. This method is more convenient than the traditional disassembly method, that is: when it is necessary to disassemble the upper support plate 1, the fixing bolts 5 between the upper support plate 1 and the connecting column 7 need to be disassembled. The overall separation and disassembly steps are more convenient and the disassembly is faster, which is very convenient for the overall transportation and maintenance;

[0031] During the movement of the reset frame 3, the support column 10 will also be pushed into the upper support plate 1 at the same time. During the movement of the support column 10, the second spring 13 will be compressed until the pushing block 14 completely enters the upper support plate 1. At this time, after releasing the reset frame 3, the reset frame 3 will be reset due to the elastic forces of the support column 10 and the second spring 13, which is convenient for subsequent use.

[0032] The working principle provided by the present utility model is as follows: When installing between the upper support plate 1 and the connecting column 7, only the upper part of the connecting column 7 needs to be sent into the inside of the upper support plate 1. In this process, since the side of the engaging block 9 close to the installation groove 15 is inclined from the edge close to the installation groove 15 towards the direction close to the first spring 11, when the engaging block 9 contacts the upper support plate 1, the upper support plate 1 pushes the engaging block 9, causing the engaging block 9 to be pushed into the inside of the connecting column 7. During the movement of the engaging block 9, the first spring 11 will be compressed. Until the engaging block 9 moves to the position of the installation groove 15 provided inside the upper support plate 1, the driving force of the first spring 11 causes the engaging block 9 to enter the inside of the upper support plate 1, completing the fixation between the upper support plate 1 and the connecting column 7. This structure is simpler than the traditional one which requires the upper support plate 1 to be placed upside down on the ground and requires multiple people to cooperate to flip and carry the fixed lower support plate 6 and the connecting column 7. The overall structure is simple and the operation is more straightforward, making the overall installation process more convenient;

[0033] For the disassembly of the upper support plate 1 and the connecting column 7, the reset frame 3 can be pushed towards the upper support plate 1, so that the pushing block 14 can be sent into the inside of the upper support plate 1. In this process, since one side of the pushing block 14 fits with the side of the engaging block 9 away from the first spring 11, during the movement of the pushing block 14, the engaging block 9 will be continuously pushed into the inside of the connecting column 7, and finally the engaging block 9 will completely enter the inside of the connecting column 7. At this time, the upper support plate 1 and the connecting column 7 can be separated;

[0034] During the movement of the reset frame 3, the support column 10 will be simultaneously pushed into the inside of the upper support plate 1. During the movement of the support column 10, the second spring 13 will be compressed. Until the pushing block 14 completely enters the inside of the upper support plate 1, when the reset frame 3 is released at this time, the reset frame 3 will be reset due to the elastic force of the support column 10 and the second spring 13, which is convenient for subsequent use;

[0035] Among them, for the installation and disassembly between the lower support plate 6 and the connecting column 7, it can be achieved only by installing the fixing bolt 5 on the lower support plate 6 and the connecting column 7 and removing the fixing bolt 5 from the lower support plate 6 and the connecting column 7.

[0036] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated here.

[0037] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, are similarly included in the patent protection scope of the present utility model.
