[0030] The clamping assembly is symmetrically arranged on the upper surface of the mounting seat 1 and is used to clamp the conversion plate body 3, thereby further improving the stability of the conversion plate body 3 after installation.

[0031] The above working principle: when the conversion plate body 3 needs to be installed, it is only necessary to first fix the mounting base 1 on the vehicle by means of bolts and other tools, and then plug the connecting plate 5 into the interior of the fixing frame 2. When the connecting plate 5 is fully plugged into the interior of the fixing frame 2, the connecting plate 5 and the fixing frame 2 are fixed by means of a fixing assembly. At this time, the conversion plate body 3 and the mounting base 1 can be fixed, so that the conversion plate body 3 can be installed. When the conversion plate body 3 is damaged and needs to be disassembled for inspection and repair, it is only necessary to disassemble the connecting plate 5 and the fixing frame 2 conveniently by means of a disassembly assembly, so that it is convenient for the staff to disassemble the conversion plate body 3. The clamping assembly can effectively clamp and fix the conversion plate body 3, so as to further improve the stability of the conversion plate body 3 after installation, saving time and effort.

[0032] In order to conveniently fix the connecting plate 5 to the fixing frame 2, so as to fix the conversion plate body 3 to the mounting seat 1, the fixing assembly includes a first telescopic rod 9 symmetrically arranged inside the two receiving grooves 8, and the telescopic ends of the plurality of first telescopic rods 9 are fixedly connected with the plug-in rod 10, and the outer sides of the plurality of first telescopic rods 9 are sleeved with a return spring 11, and the plurality of return springs 11 are in contact between the plug-in rod 10 and the receiving groove 8. The outer walls of the fixing frame 2 and the connecting plate 5 are provided with guide grooves for the plug-in rod 10 to move. When it is necessary to fix the connecting plate 5 to the fixing frame 2, only the first The plug-in rod 10 is pressed, and the plug-in rod 10 will squeeze the first telescopic rod 9 and the reset spring 11 synchronously, and then the connecting plate 5 is plugged into the interior of the fixed frame 2. At this time, the connecting plate 5 will drive the plug-in rod 10 to move synchronously. When the connecting plate 5 drives the plug-in rod 10 to move into the guide grooves on both sides of the outer wall of the fixed frame 2, the reset spring 11 is reset, driving the plug-in rod 10 to reset and move synchronously. When the plug-in rod 10 is plugged into the guide grooves on both sides of the outer wall of the fixed frame 2, the connecting plate 5 can be fixed to the fixed frame 2, and the conversion plate body 3 can be fixedly installed with the mounting seat 1.

[0033] Considering that when the conversion plate body 3 is damaged, it needs to be disassembled for repair or replacement, the disassembly assembly includes fixed blocks 7 symmetrically arranged on the front end surface and the rear end surface of the fixing frame 2, the exterior of the plurality of fixed blocks 7 is fixedly connected with a second telescopic rod 20, the telescopic ends of each two second telescopic rods 20 are fixedly connected with a pressing plate 17, the exterior of the plurality of second telescopic rods 20 is sleeved with a resisting spring 21, the plurality of resisting springs 21 are in contact between the pressing plate 17 and the fixed block 7, and the opposite sides of the two pressing plates 17 are symmetrically provided with a squeezing rod 18 for squeezing the plug-in rod 10. When the conversion plate body 3 needs to be disassembled, it is only necessary to press the pressing plate 17 first. At this time, the pressing plate 17 will drive the squeezing rod 18 to move synchronously. When the squeezing rod 18 squeezes the plug rod 10 into the interior of the fixed frame 2, the conversion plate body 3 is pulled. At this time, the conversion plate body 3 will drive the connecting plate 5 to move synchronously. When the connecting plate 5 body is completely separated from the interior of the fixed frame 2, the conversion plate body 3 can be disassembled, so that it is convenient for the staff to repair or replace the conversion plate body 3. During the movement of the pressing plate 17, the second telescopic rod 20 and the resistance spring 21 are also squeezed synchronously. When the conversion plate body 3 is disassembled, the pressing plate 17 is released. At this time, the resistance spring 21 is reset, which can drive the pressing plate 17 to reset and move synchronously.

[0034] In order to further improve the stability of the conversion plate body 3 after installation, the clamping assembly includes a fixed plate 4 symmetrically arranged on the upper surface of the mounting seat 1, the interior of the fixed plate 4 is fixedly connected with an inner plate 12, the front end surface and the rear end surface of the inner plate 12 are fixedly connected with sliding rods 13, the other ends of the plurality of sliding rods 13 are fixedly connected to the inner wall of the fixed plate 4, the interior of the fixed plate 4 is symmetrically provided with a movable plate 14, the interiors of the plurality of movable plates 14 are provided with guide grooves for the sliding rods 13 to move, the exteriors of the plurality of sliding rods 13 are sleeved with connecting springs 15, the plurality of connecting springs 15 are in contact between the movable plate 14 and the fixed plate 4, the upper surface of the fixed plate 4 is provided with a guide groove for the movable plate 14 to move, the upper surfaces of the plurality of movable plates 14 are fixedly connected with clamping plates 16, when needed To fix and clamp the conversion plate body 3, you only need to move the clamping plate 16 first.

During the movement of the movable plate 14, the connecting spring 15 will be squeezed synchronously. At this time, the conversion plate body 3 and the mounting seat 1 are fixed again. When the conversion plate body 3 and the mounting seat 1 are fixed, the clamping plate 16 is released. At this time, the connecting spring 15 is reset, driving the movable plate 14 to move synchronously, and the movable plate 14 then drives the clamping plate 16 to move synchronously. When the clamping plate 16 contacts the outside of the conversion plate body 3, the conversion plate body 3 can be effectively fixed and clamped by the clamping plate 16, thereby further improving the stability of the conversion plate body 3 after installation.
