[0005] The utility model is further configured as follows: a limiting ring is arranged at one end of the clamping block close to the bottom wall of the fixing groove, and a limiting flange which is arranged to conflict with the limiting ring is arranged at the opening of the fixing groove.

[0006] The utility model is further configured as follows: a first bevel is provided at one end of the clamping block close to the aluminum profile body.

[0007] The utility model is further configured as follows: the fixing plate is configured to be matched with the cross sections of the two aluminum profile bodies.

[0008] The utility model is further configured as follows: a second bevel is arranged on the circumference of one end of the plug-in rod away from the fixing plate.

[0009] By adopting the above technical solution, the practical aluminum profile can be quickly connected without drilling holes during connection, is not easy to cause damage to the aluminum profile body, and improves the overall aesthetics. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Reference Figures 1 to 3 The utility model is further described in detail.

[0015] The utility model discloses a connecting piece for aluminum profiles, comprising two aluminum profile bodies 1 and an aluminum profile connecting piece 2 arranged between the two aluminum profile bodies 1, the cross section of the aluminum profile bodies 1 is in a well shape, a cavity 10 is arranged inside the aluminum profile bodies 1, the inner diameter of the cavity 10 is smaller than the inner diameter of the aluminum profile bodies 1, the aluminum profile connecting piece 2 comprises a fixing plate 20 and a plug-in rod 21 arranged on both sides of the fixing plate 20, the plug-in rod 21 is arranged in a sliding fit with the cavity 10, and fixing grooves 210 are respectively opened on the four side walls of the plug-in rod 21, a card block 22 arranged in a sliding fit is arranged in the fixing groove 210, a spring 23 is arranged between the card block 22 and the fixing groove 210, and card grooves 11 adapted to the card block 22 are respectively arranged on the four inner walls of the cavity 10. A limit ring 220 is disposed at one end of the clamping block 22 close to the bottom wall of the fixing groove 210, and a limit flange 211 is disposed at the opening of the fixing groove 210 to abut against the limit ring 220. The fixing plate 20 is adapted to the cross section of the two aluminum profile bodies 1.

[0016] Furthermore, in order to allow the clamping block 22 to smoothly enter the cavity 10 , a first bevel 3 is provided at one end of the clamping block 22 close to the aluminum profile body 1 .

[0017] Furthermore, in order to allow the plug rod 21 to smoothly enter the cavity 10 , a second bevel 4 is provided on the circumference of one end of the plug rod 21 away from the fixing plate 20 .

[0018] Working principle: When it is necessary to connect two aluminum profile bodies 1, you can hold the fixing plate 20 and then align the plug rod 21 on one side with the cavity 10 at one end of one of the aluminum profile bodies 1 and insert it. When the plug rod 21 is inserted, the block 22 set on the four sides of the plug rod 21 will slide toward the fixed groove 210 under the squeezing force of the inner wall of the cavity 10, and the spring 23 will be forced to shrink. When the plug rod 21 is fully inserted, the block 22 will slide to the clamping groove 11, and the block 22 will slide into the clamping groove 11 under the restoring force of the spring 23 itself for clamping cooperation. Through the clamping cooperation of multiple blocks 22 and the clamping groove 11, the plug rod 21 will be firmly fixed on the aluminum profile body 1, and then people can hold another aluminum profile body 1 and align it with the plug rod 21 on the other side of the fixing plate 20 to insert it, so that the two aluminum profile bodies 1 can be quickly connected and fixed through the aluminum profile connector 2, which is very convenient and practical to install.

[0019] The practical aluminum profile can be quickly connected without drilling holes during connection, is not likely to cause damage to the aluminum profile body 1, and improves the overall aesthetics.
