Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3The utility model provides an embodiment: a split type easy-to-assemble automotive aluminum alloy, including profile a1, the end of profile a1 is detachably connected to profile b2, the end of profile a1 is fixedly connected to a slider b10, the outer wall of slider b10 is slidably connected to the inner wall of profile b2, the slider b10 is slid along the inner wall of profile b2, and the profile a1 is moved to a designated position for installation, the inner wall of slider b10 is slidably connected to two sets of buckle components, the buckle components include a clamping block 11, the outer wall of clamping block 11 The two sets of blocks 11 are slidably connected to the inner wall of the slider b10, and the two sets of blocks 11 are elastically connected by the return spring a12. The two ends of the return spring a12 are respectively fixedly connected to the inner ends of the two sets of blocks 11. Before the slider b10 slides in, it is necessary to manually press the block 11 to squeeze the return spring a12 to completely retract. Only then can the slider b10 slide into the inner wall of the profile b2. At the same time, the elastic force generated by the deformation of the return spring a12 gives the block 11 a reverse thrust to reset it. The inner wall of the profile b2 is provided with a card slot 13, and the outer wall of the card block 11 is carded with the inner wall of the card slot 13. When sliding until the card slot 13 is aligned with the card block 11, the return spring a12 will push the card block 11 into the card slot 13, and perform a preliminary fixation on the two groups of profiles to be connected. The inner wall of the profile b2 is elastically connected to a pressing rod 15 through a return spring b14, and one end of the return spring b14 is fixedly connected to the inner wall of the pressing rod 15, and the other end of the return spring b14 is fixedly connected to the inner wall of the profile b2, pressing inward. Pressing the pressing rod 15 can squeeze the reset spring b14 and move it inward. At the same time, the elastic force generated by the deformation of the reset spring b14 gives the pressing rod 15 a thrust in the opposite direction, prompting it to reset. The outer wall of the pressing rod 15 is slidably connected to the inner wall of the profile b2, and the inner end of the pressing rod 15 is in contact with the outer end of the block 11. Pressing the pressing rod 15 inward can press the block 11 out of the slot 13. At this time, the slider b10 can continue to slide to change the position of the profile a1 relative to the profile b2.

[0032] Reference Figure 1 , Figure 2 and Figure 4, the outer walls of profile a1 and profile b2 are detachably connected with a fixing frame 3, the outer wall of the fixing frame 3 is fixedly connected with multiple groups of rectangular plates 4, the inner wall of the rectangular plate 4 is slidably connected with a mounting seat 7, the outer wall of the mounting seat 7 is slidably connected with the inner wall of the profile b2, the mounting seat 7 needs to slide to the end along the inner wall of the profile a1 first before it can cooperate with the slider b10 to slide into the profile b2, the inner wall of the rectangular plate 4 is provided with a slide groove 5, the side wall of the mounting seat 7 is fixedly connected with a slider a6, the outer wall of the slider a6 is slidably connected with the inner wall of the slide groove 5, the slider a6 is rectangular and can only slide along the inner wall of the slide groove 5 and cannot be flipped to ensure that the bolts 9 can be transferred into the mounting seat 7 so that the two are close to each other, and the two groups of profiles are fixed with the fixing frame 3, the inner wall of the mounting seat 7 is threaded with a bolt 9, the inner side of the bolt 9 is in contact with a gasket 8, the outer wall of the gasket 8 is in contact with the inner wall of the fixing frame 3, the gasket 8 can increase the connection area, evenly distribute the pressure, reduce the local load on the connecting piece, and prevent the deformation or damage of the connecting piece.

[0033] Working principle: first fix the fixing frame 3 on the profile a1, then press the block 11 inward to squeeze the return spring a12 and retract it, then slide it along the inner wall of the profile b2. At the same time, the mounting seat 7 slides in together along the inner wall of the profile b2. After sliding to the specified position, the block 11 is snapped into the corresponding slot 13 under the action of the return spring a12. When it has not slid to the specified slot 13, the pressing rod 15 can be pressed inward to squeeze the return spring b14 and move inward, so that the block 11 is disengaged from the slot 13, thereby continuing to slide the slider b10 along the inner wall of the profile b2, driving the position of the profile a1 to change. When using the fixing frame 3 to fix the two groups of profiles, pad the gasket 8 and align the bolt 9 with the inner wall groove of the mounting seat 7 and turn it in. The two cooperate with each other to fix the connected profiles.
