[0033] The crossbeam body 4 is snapped into the connecting block 2 3 to realize the installation of the connecting block 1 2 and the crossbeam body 4. When the connecting block 2 3 enters the connecting block 1 2, the two sliders 7 respectively squeeze the inner wall of the connecting block 2 3 through their respective bevel edges to slide into the slide groove 1 5 and approach each other, and at the same time, the two operating rods 8 are pressed to approach each other and squeeze the spring 1 9 in the middle, until the connecting block 2 3 completely enters the connecting block 1 2, it will press against the buffer plate 14 and squeeze multiple springs 15. At this time, the inner wall of the connecting block 2 3 will no longer squeeze the two sliders 7, and the spring 1 9 will rebound, respectively pushing the two operating rods 8 away from each other. , so that the two sliders 7 slide in the slide groove 5 and move away from each other until they are engaged in the two slots 10, completing the fixation of the connecting block 2 and the beam body 4 after installation. When it is necessary to take it out, pull the two operating rods 8 to slide in the slide groove 6 respectively and move them closer to each other. At this time, the two operating rods 8 will squeeze the spring 9 and drive the two sliders 7 to move closer to each other, so that the two sliders 7 leave the two engaged slots 10. At this time, the multiple springs four 15 will rebound the buffer plate 14, push the buffer plate 14 out partially, and then move the connecting block 2 3 away from the engaged connecting block 2, completing the disassembly and separation of the connecting block 2 and the beam body 4.

[0034] Reference Figure 4 The stabilizing component includes a limit block 11 and a groove 13, and the limit block 11 and the groove 13 are both set in two. The two connecting blocks 2 3 are respectively opened on the right side of the middle of the connecting block 2, and the two limit blocks 11 are respectively slidably connected in the two grooves 13.

The two limit blocks 11 are both set between the two operating rods 8.

[0035] When the connecting block 1 2 and the connecting block 2 3 need to be installed and engaged, the two limit blocks 11 are slid to the right into the two grooves 13 respectively, and the springs 2 12 on both sides are squeezed. After the connecting block 1 2 and the connecting block 2 3 are installed, the limit blocks 11 are released. At this time, the springs 2 12 on both sides will rebound the limit blocks 11 and push them out to the right. The two operating rods 8 are limited by the limit blocks 11 on both sides to avoid being squeezed close to each other. When the connecting block 1 2 and the connecting block 2 3 need to be disassembled, the two limit blocks 11 are slid to the right into the two grooves 13 respectively, and the springs 2 12 on both sides are squeezed. At this time, the connecting block 2 3 can be separated from the engaged connecting block 1 2.

[0036] Reference Figure 4-Figure 6 A threaded groove 17 opposite to each other is opened in the middle of the mounting frame 1, and a circular groove 16 opposite to each other is opened on the right side of the mounting frame 1. The two threaded grooves 17 are respectively arranged inside the two circular grooves 16, and the left sides of the inner walls of the two circular grooves 16 are fixedly connected with springs 19, and the right sides of the two circular grooves 16 are fixedly connected with extrusion rings 20. The inner walls of the two threaded grooves 17 are threadedly connected with screws 18, and the right sides of the two screws 18 are fixedly connected with screw surfaces 25, and the two screw surfaces 25 are respectively against the right sides of the two extrusion rings 20. An extension block 21 opposite to each other is fixedly connected to the right side of the mounting frame 1, and the two extension blocks 21 correspond to the two threaded grooves 17 respectively, and the outer walls of the two threaded grooves 17 are threadedly connected with protective covers 22.

[0037] After the connecting block 1 2 and the crossbeam body 4 are fixed by the connecting block 2 3, the mounting frame 1 is attached to the mounting position in the vehicle, and the two screws 18 are respectively threaded into the two thread grooves 17, and the mounting frame 1 is installed in the vehicle. When the screw 18 threads into the extension block 21, the screw surface 25 will press against the extrusion ring 20 and squeeze the spring five 19. At this time, the spring five 19 is squeezed to drive the extrusion ring 20 into the circular groove 16, and the extrusion ring 20 is rebounded by the spring five 19. At the same time, the screw 18 and the screw surface 25 are pushed in the opposite direction to increase the preload force, and then the protective cover 22 is threadedly rotated to cover the outer wall of the extension block 21 and press against the screw surface 25, so as to seal and protect the screw surface 25.

[0038] Reference Figure 1 and Figure 2 A weight-reducing groove 23 is provided on the outer wall of the crossbeam body 4, and evenly distributed reinforcing ribs 24 are fixedly connected to the right side of the mounting frame 1. Multiple reinforcing ribs 24 are respectively fixedly connected to the upper and lower sides of the connecting block 2, and two protective covers 22 are respectively arranged between the multiple reinforcing ribs 24.

[0039] The weight-reducing groove 23 is used to reduce the gravity of the beam body 4, and the plurality of reinforcing ribs 24 are used to strengthen the stability of the connecting block 1 2, thereby preventing the connecting block 2 3 and the beam body 4 from falling after installation.

[0040] Working principle: when in use, align the crossbeam body 4 with the connecting block 2 3 and engage it. During this period, the two sliders 7 are squeezed into the slide groove 1 5 by the inner wall of the connecting block 2 3 through their respective oblique edges and approach each other. The middle spring 1 9 is squeezed by the two operating rods 8. When the connecting block 2 3 completely enters the connecting block 2, the spring 1 9 will rebound to the two operating rods 8, so that the two sliders 7 slide in the slide groove 1 5 and move away from each other. After moving away, the two sliders 7 will be respectively engaged in the two slots 10 to fix the installation of the connecting block 2 and the crossbeam body 4. When separating, pull the two operating rods 8 closer to each other, the operating rod 8 will slide in the slide groove 2 6, and at the same time squeeze the spring 1 9 and drive the two sliders 7 to move closer to each other. At this time, the two sliders 7 will respectively leave the engagement. Two card slots 10, and then pull the connecting block 2 3 out of the engaged connecting block 1 2, and the disassembly of the connecting block 1 2 and the beam body 4 can be completed. When the connecting block 1 2 and the beam body 4 are installed and fixed, align the mounting frame 1 with the installation position in the vehicle, and then respectively thread the two screws 18 into the two thread grooves 17 to realize the installation of the mounting frame 1 in the vehicle. After the screw 18 threads into the extension block 21, it presses against the extrusion ring 20 through the screw surface 25, and at the same time, the extrusion spring 5 19 is squeezed. The spring 5 19 drives the extrusion ring 20 into the circular groove 16. At the same time, the rebound of the spring 5 19 pushes the screw surface 25 in the opposite direction through the extrusion ring 20, thereby increasing the preload force to prevent the screw 18 from loosening in the thread groove 17, and providing stability for the installation of the mounting frame 1 in the vehicle.
