[0002] Electronic charts are a form of digital charts that are used to display the chart information required for navigation on electronic devices. Compared with traditional paper charts, electronic charts have many advantages, including: real-time updates, electronic charts can be updated through the network, ensuring that navigators always have the latest chart information. Although electronic charts have many advantages, you also need to pay attention to the power and line connection of electronic devices when using them to ensure that you can always rely on these electronic devices during navigation.

[0003] However, the above device still has the following problems during implementation:

[0004] The existing technology requires attention to line connection issues when using electronic nautical charts. After the existing electronic nautical charts are placed in a certain place, multiple lines need to be connected on the back side. If there is no component to prevent the lines from detaching, once the line becomes loose during use, it may cause errors in the display of the electronic nautical chart. Therefore, an electronic nautical chart safety protection device is specially proposed to solve the above problems. Utility Model Content

[0009] As a preferred embodiment of the present invention, the positioning assembly includes a splint, and two opposite sides of the two splints are fixedly connected with springs, and the number of springs is five. The side of the spring close to the nautical chart display is fixedly connected to the nautical chart display, and the left and right sides of the splint are fixedly connected with L-shaped plates. By setting the positioning assembly, after the splint drives the plug-in block to be inserted into the plug-in slot, the pressure of the spring on the splint will make the splint fit tightly with the connector and the plug-in part, so that the splint will not drive the plug-in block to detach.

[0010] As a preferred embodiment of the utility model, the top and bottom of the connector and the connecting piece are fixedly connected with a plug-in block, and a plug-in slot used in conjunction with the plug-in block is provided on the side of the splint close to the plug-in block, and the plug-in block is plug-connected to the inner cavity of the plug-in slot. By arranging the plug-in block and the plug-in slot, because the number of the connecting piece and the connector is five, the five plug-in blocks are then inserted into the plug-in slot, and the positions of the connecting piece and the connector can be positioned at this time.

[0011] As a preferred embodiment of the utility model, the control component includes two extrusion parts, which are movably connected to the left and right sides of the splint, and the top and bottom of the extrusion parts are movably connected with extrusion rods, the front side of the extrusion rod is fixedly connected to the L-shaped plate, and a travel hole is opened on the right side of the extrusion part. By setting the control component, when it is necessary to control the two splints to move at the same time, the inclined surface of the extrusion plate will squeeze the two extrusion rods when the extrusion plate moves, and the extrusion rods will move away from each other due to the squeezing of the inclined surface.

[0023] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 4 As shown, an electronic chart safety protection device provided by an embodiment of the utility model comprises a chart display 1, five plug connectors 2 and five connectors 3, wherein the plug connector 2 is fixedly mounted on the rear side of the chart display 1, and the connector 3 is plugged and connected to the inner cavity of the plug connector 2;

[0025] A positioning assembly 4 for positioning the plug connector 2 and the connector 3, wherein the positioning assembly 4 is arranged at the top and the bottom of the plug connector 2;

[0026] The control component 5 is used to control the two positioning components 4 at the same time, and the control component 5 is arranged on the left and right sides of the nautical chart display 1.

[0027] refer to Figure 3 The positioning assembly 4 includes a clamping plate 41, and springs 42 are fixedly connected to the opposite sides of the two clamping plates 41, and the number of the springs 42 is five. The side of the spring 42 close to the nautical chart display 1 is fixedly connected to the nautical chart display 1, and L-shaped plates 43 are fixedly connected to the left and right sides of the clamping plates 41.

[0028] The above solution is adopted: by setting the positioning component 4, after the clamping plate 41 drives the plug-in block 6 to be inserted into the plug-in slot 7, the pressure of the clamping plate 41 is exerted by the spring 42, so that the clamping plate 41 will fit tightly with the connector 3 and the plug-in component 2, so that the clamping plate 41 will not drive the plug-in block 6 to detach.

[0029] refer to Figure 3 The top and bottom of the connector 2 and the connector 3 are fixedly connected with a plug-in block 6. A plug-in slot 7 for use with the plug-in block 6 is provided on one side of the clamp 41 close to the plug-in block 6. The plug-in block 6 is plugged into the inner cavity of the plug-in slot 7.

[0030] The above solution is adopted: by setting the plug-in block 6 and the plug-in slot 7, because the number of the connectors 3 and the connectors 2 is five, and then the five plug-in blocks 6 are inserted into the plug-in slot 7, the positions of the connectors 3 and the connectors 2 can be positioned.

[0031] refer to Figure 3 The control component 5 includes two extrusion members 51, which are movably connected to the left and right sides of the clamping plate 41. The top and bottom of the extrusion member 51 are movably connected to an extrusion rod 52. The front side of the extrusion rod 52 is fixedly connected to the L-shaped plate 43. A travel hole 53 is opened on the right side of the extrusion member 51.

[0032] By adopting the above solution, by setting the control component 5, when it is necessary to control the two clamping plates 41 to move simultaneously, the inclined surface of the extrusion plate 10 will squeeze the two extrusion rods 52 when it moves, and the extrusion rods 52 will move away from each other due to the squeezing of the inclined surface.

[0033] refer to Figure 4 The inner cavity of the stroke hole 53 is slidably connected with a stroke rod 8, and the side of the stroke rod 8 close to the nautical chart display 1 is fixedly connected to the nautical chart display 1.

[0034] By adopting the above solution, by setting the travel rod 8, when the extrusion plate 10 moves, the travel rod 8 and the travel hole 53 can locate the moving position of the extrusion plate 10, so that the extrusion plate 10 will not move around when being extruded.

[0035] refer to Figure 4The bottom of the extrusion member 51 is fixedly connected to an inclined plate 9, and the bottom of the inclined plate 9 is rotatably connected to an extrusion plate 10 via a rotating shaft.

[0036] The above solution is adopted: by setting the inclined plate 9 and the extrusion plate 10, when it is necessary to control the movement of the extrusion plate 10, because the extrusion plate 10 and the inclined plate 9 are connected by a rotating shaft, when the extrusion plate 10 moves to extrude the inclined plate 9, the inclined plate 9 will drive the extrusion plate 10 to move.

[0037] refer to Figure 4 The bottom of the extrusion plate 10 is rotatably connected to a control plate 11 via a rotating shaft. The shape of the control plate 11 is U-shaped, and the bottom of the control plate 11 passes through the nautical chart display 1 and extends to the bottom of the nautical chart display 1.

[0038] By adopting the above scheme: by setting the control board 11, when it is necessary to simultaneously control the two extrusion plates 10 to move the extrusion inclined plate 9, the control board 11 is pushed up to drive the two extrusion plates 10 to extrude the inclined plate 9, thereby achieving the effect of quickly controlling the two extrusion plates 10.

[0039] The working principle of this utility model:

[0040] When in use, the electronic nautical chart is placed on the desktop, and then the control panel 11 is pushed up to drive the two extrusion plates 10 to squeeze the inclined plate 9. The inclined plate 9 is squeezed to drive the extrusion piece 51 to move on the surface of the stroke rod 8. When the extrusion plate 10 moves, the inclined surface of the surface will squeeze the two extrusion rods 52. The extrusion rods 52 are squeezed by the inclined surface and move away from each other. The movement of the extrusion rods 52 will drive the L-shaped plate 43 to move. The movement of the L-shaped plate 43 will drive the clamping plate 41 to move. The movement of the clamping plate 41 will squeeze the spring 42. When the plug-in slot 7 on the clamping plate 41 is no longer in contact with the plug-in block 6, pick up the connector 3 and dock it with the connector 2. At this time, the connector 3 and the plug-in blocks 6 at the top and bottom of the plug-in slot 7 can be aligned with the plug-in slot 7. Then the control panel 11 can be released, and the elastic deformation of the spring 42 will drive the clamping plate 41 back to its original position. The movement of the clamping plate 41 will drive the plug-in block 6 to be inserted into the inner cavity of the plug-in slot 7. At this time, the connector 3 can be prevented from driving the line out.

[0041] In summary: the electronic nautical chart safety protection device, by setting the coordinated use of the connector 2, the connector 3, the positioning component 4 and the control component 5, pick up the connector 3 and connect it to the connector 2, then the connector 3 and the plug-in blocks 6 at the top and bottom of the plug-in slot 7 can be aligned with the plug-in slot 7, and then the control board 11 can be released, and the elastic deformation of the spring 42 will drive the clamp 41 back to its original position, and the movement of the clamp 41 will drive the plug-in block 6 to be inserted into the inner cavity of the plug-in slot 7, then the connector 3 can be prevented from driving the line to disengage, which solves the problem that after the electronic nautical chart is placed in a certain place, the back side needs to connect multiple lines. If there is no component to prevent the lines from disengaging, once that line becomes loose during use, it may cause the electronic nautical chart to display errors.
