When two aluminum body profiles need to be connected, the connecting device at one end of one of the profiles 1 is retracted into the interior of the profile 1 through the limiting device 6, and then the end of the other profile 1 to be connected is connected through the connecting device 2, so that the two aluminum body profiles can be connected without using special tools. After the connection is completed, the connecting device 2 that does not need to be connected is retracted into the interior of the profile 1 through the limiting device 6 to prevent the connecting device from extending out of the profile 1 and affecting the connection between the aluminum body profile and other body parts.

[0022] In this embodiment, the limiting device 6 includes a support plate 7, which is fixed to the inside of the profile 1. A booster spring 8 is fixed to the middle of the side of the support plate 7 close to the connecting device 2. A mounting block 9 is fixed to the end of the booster spring 8 away from the support plate 7. A limiting groove 16 is symmetrically provided on the right side above the front and rear surfaces of the mounting block 9. A limiting spring 17 is fixed to the bottom of the limiting groove 16. A limiting block 10 is fixed to the end of the limiting spring 17 away from the bottom of the limiting groove 16. The limiting block 10 is inserted into the inside of the first limiting hole 14. A guide block 11 is symmetrically fixed to the left side in the middle of the front and rear sides of the mounting block 9. The guide block 11 is inserted into the inside of the guide groove 4, pressing the two limiting blocks. 10 moves the limit device into the profile 1 through the guide block 11 and the connecting device 2. When the guide block 11 and the guide groove 4 are in contact with the inner wall near the middle of the profile 1, the limit block 10 is inserted into the second limit hole 5 under the action of the limit spring 17, and the connecting device 2 is fixed to the inside of the profile 1. At this time, the limit block 10 is pressed and the limit device 6 moves toward the end of the profile 1 under the action of the support plate 7 and the assisting spring 8, driving the connecting device 2 to move toward the end of the profile 1. When the guide block 11 and the guide groove 4 are in contact with the inner wall near the end of the profile 1, the limit block 10 is inserted into the first limit hole 14 under the action of the limit spring 17, and the connecting device 2 is fixed to the outside of the end of the profile 1.

A clamping block 13 is fixed to the end of the connecting spring 19 away from the bottom of the connecting groove 18. The clamping block 13 is pressed to insert the connecting device 2 into the port of the profile 1 to which another aluminum body profile needs to be connected. When the clamping block 13 and the connecting hole 3 at the port of the profile 1 to which another aluminum body profile needs to be connected are relative to each other, the clamping block 13 is inserted into the inside of the connecting hole 3 at the port of the profile 1 to which another aluminum body profile needs to be connected under the action of the connecting spring 19, and the connection of the two aluminum body profiles is completed without using special tools.

[0024] In this embodiment, a glue coating groove 15 is opened in the middle of the bottom of the profile 1. After the colloid is applied to the glue coating groove, the side outer panel is connected to the aluminum body profile through the colloid. The thickness and position of the colloid can be controlled, and the assembly accuracy is improved without affecting the assembly relationship between the lap joint and other positions. The depth of the groove can better control the amount of colloid in the groove, thereby achieving the effect of controlling costs.

[0025] In this embodiment, the outer wall of the mounting block 9 fits with the inner wall of the profile 1, and the outer wall of the connecting block 12 fits with the inner wall of the profile 1, which can ensure that the connecting device 2 and the limiting device 6 move smoothly inside the profile 1, and at the same time ensure that the two aluminum body profiles will not shake when connected.
