It should be understood that the objects described in this way can be interchanged under appropriate circumstances. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0028] Example 1: Reference Figure 1-5 A lock body suitable for aluminum alloy profiles includes a lock body main body 11 for fixing on the aluminum alloy profile, an outer side surface of the lock body main body 11 is provided with an outer plate 12, and an inner side surface of the lock body main body 1 is provided with an adjusting expansion piece 2, the adjusting expansion piece 2 includes a left side plate 21, a right side plate 22 and a rear side plate 23 to form a lock body clamping cavity 20 with a bottom at one end and an opening at the other end, the lock body clamping cavity 20 is clamped on the inner side surface of the lock body main body 11, and an adjusting transmission piece is provided for transmitting the inner side surface of the rear side plate 23 of the adjusting expansion piece to move toward the inner side surface of the lock body.

[0029] Among them, the lock body main body 11 is provided with a through hole 102 which passes through from its outer plate toward the inner side surface of the lock body main body 11, and the rear side plate 23 of the adjusting expansion member 2 is provided with an adjusting screw hole 24 at a position corresponding to the through hole 102, and the adjusting transmission member 2 includes an adjusting screw 3 which passes through the through hole of the lock body main body 1 and extends to the adjusting screw hole 24 of the rear side plate 23 of the adjusting expansion member 2, and the thread of the adjusting screw 24 is matched with the thread of the adjusting screw hole 23, and the adjusting screw hole 24 of the adjusting expansion member 2 extends from a side close to the inner side surface of the lock body main body 11 toward the outer side surface of the adjusting expansion member 2, and the adjusting screw 24 has a limiting end surface 31.

[0030] When in use, if the length of the left side plate 21 and the right side plate 22 is greater than the distance between the inner side plate and the outer side surface of the lock body 11, preferably at least greater than 2 mm, then as the inner surface of the rear side plate 23 presses toward the inner side surface of the lock body 11, the other side of the left side plate 21 and the right side plate 22 will abut against the outer side plate and force the left side plate and the right side plate to expand outward, especially when subsequently cooperating with the inner oblique extension portion 25 or the inner arc extension portion of the lock body, the oblique extension portion and the inner arc extension portion can make the other side of the left side plate and the right side plate expand outward to expand their expanded diameter.

[0031] Among them, in order to further increase the external expansion diameter of the adjustment expansion piece 2, one side of the left side plate 21 and the right side plate 22 of the adjustment expansion piece 2 is connected to the inner side surface of the rear side plate 23, and the other side of the left side plate 21 and / or the right side plate 22 is provided with an inner oblique extension portion 25 or an inner arc extension portion extending obliquely toward the left side surface and the right side surface of the corresponding lock body main body 11. Specifically, the corresponding inner oblique extension portion 25 or the inner arc extension portion of the left side plate 21 and the right side plate 22 can make the inner side surface of the rear side plate expand toward the left side plate 21 and the right side plate 22 when the inner side surface of the lock body main body 11 is adjusted and moved toward the inner side surface of the lock body main body 11, so as to expand its diameter. In particular, it can be used in conjunction with the trapezoidal lock body main body 11, and its expansion effect is better. Specifically, if it is used in conjunction with the side protrusion at the back, the expansion effect is better.

[0032] Among them, the adjustment expansion member 2 includes a left side plate 21, a right side plate 22 and a rear side plate 23, which are surrounded by a "U"-shaped lock body clamping cavity 20 for clamping the lock body main body 11, and the lock body main body 11 can be formed by integral stamping to ensure its overall strength.

[0033] Among them, in order to further increase the external expansion diameter of the adjustment expansion piece 2, at least one group of side protrusions 13 are arranged on the left side and / or right side of the lock body 11 at the position corresponding to the installation of the adjustment expansion piece. Preferably, the side protrusions 13 can be multiple groups of protrusions or strip-shaped protrusions.

[0034] Preferably, at least one group of side protrusions is arranged close to the subsequent first clamping position or second clamping position direction to enhance the overall fixing effect on the aluminum profile opening and improve the overall tolerance rate.

[0035] Among them, the width of the outer plate 12 is greater than the width of the lock body 11, and the side protrusion 13 of the lock body 11 is arranged at a position close to or in contact with the outer plate 12. Specifically, the outer plate is used to limit the depth of the lock body embedded in the aluminum profile opening and further improve the expansion effect to better limit the lock body 11 from being separated from the aluminum profile opening.

[0036] Preferably, the side protrusion 13 of the lock body 11 extends obliquely downward from the side close to the outer plate 12 toward the inner side of the lock body 11 so that the other side of the left plate 21 and the right plate 22 are guided to expand and extend toward the side protrusion 13, thereby further making the diameter of the adjustment expansion portion 2 significantly larger than the opening diameter of the aluminum profile.

[0037] A lock hook assembly is provided, wherein the lock body 1 described in any structure of the above embodiments is provided, a locking portion is provided at the front end or rear end of a lock body main body 11 of the lock body 1, and a lock hook 4 is provided on the lock body main body 12. Preferably, the locking portion includes a first locking portion 111 and a second locking portion 112 provided at one end of the lock body main body, and the first locking portion 111 or the second locking portion 112 can be clamped on the opening of the aluminum profile, and then tightening the adjusting screw of the adjusting expansion piece on the lock body can make the lock body firmly fixed on the aluminum profile, and when disassembly is required, the above-mentioned stable state can be opened by loosening the adjusting screw to loosen the adjusting expansion piece, which is easy to disassemble and maintain.

[0038] Preferably, the first locking portion and the second locking portion may be existing elastic locking portions elastically embedded in the opening of the aluminum alloy profile.

[0039] Of course, the above are only preferred embodiments of the present invention, and are not intended to limit the scope of use of the present invention. Therefore, any equivalent changes made to the principles of the present invention should be included in the protection scope of the present invention.
