[0020] like Figure 1 and Figure 2 As shown, an embedded flat connecting locking block includes a locking block body 7 and an aluminum rod 3. The bottom of the aluminum rod 3 is recessed inward to form a groove 5. A flat connecting plate 1 extending outward horizontally is provided on one side of the locking block body 7. A latch 2 protruding outward is provided on the flat connecting plate 1. A locking hole 4 is provided at one end of the aluminum rod 3. After the aluminum rod 3 is assembled from top to bottom, it is connected by inserting the latch 2 into the locking hole 4.

[0021] In actual use, the aluminum rod 3 adopts a Z-shaped cross-section, which creates an inwardly recessed groove 5 at its bottom. The flat connecting plate 1, which connects to the aluminum rod 3 on one side of the locking block body 7, has an outwardly horizontally extending structure, and an outwardly protruding latch 2 is formed on the flat connecting plate 1. A locking hole 4 is formed at one end of the aluminum rod 3. When connecting and assembling the locking block body 7 and the aluminum rod 3, the aluminum rod 3 can be connected simply by snapping it down from top to bottom and inserting the latch 2 into the locking hole 4. After the connection is completed, the flat connecting plate 1 is completely inserted into the groove 5, so that the connection between the locking block body 7 and the aluminum rod 3 no longer forms an upwardly protruding structure. The overall size is small and the concealment is high, making the window profile more concise and beautiful after the locking block is installed.

[0022] A further improvement is made in that the locking block body 7 includes a locking block body 73, a small plastic part 74 disposed at the bottom of the locking block body 73, a locking point 71 disposed on the locking block body 73, and a rolling sleeve 72 sleeved on the locking point 71. The flat connecting plate 1 is integrally formed with the locking block body 73. The bottom of the flat connecting plate 1 is flush with the bottom of the locking block body 73, and the height of the flat connecting plate 1 and the buckle 2 is consistent with the thickness of the aluminum rod 3.

[0023] The flat connecting plug 1 is integrally formed with the lock block body 73, the structure is simpler, the molding is convenient, the firmness is good, the bottom of the flat connecting plug 1 is flush with the bottom of the lock block body 73, the height of the flat connecting plug 1 and the lock catch 2 is consistent with the thickness of the aluminum rod 3, after assembly, the lock block body and the aluminum rod 3 are consistent in profile, the appearance is higher, after actual production, the length is only 47mm, the height is only 4.5mm, it is very small, the assembled lock block is well hidden in the profile groove, the lock block is flush with the aluminum rod 3.

[0024] Further improvement is that the bottom of the lock block body 73 is provided with a limiting groove 12 penetrating through both sides, the small plastic part 74 is arranged in the limiting groove 12, both sides of the limiting groove 12 are provided with outwardly protruding clamping blocks 9, the small plastic part 74 is provided with an upwardly protruding L-shaped buckle 10, the small plastic part 74 is fixed on both sides of the clamping blocks 9 through the L-shaped buckle 10, and the width of the small plastic part 74 is greater than the width of the lock block body 73.

[0025] The small plastic part 74 is embeddedly arranged in the limiting groove 12, the concealment is better, and after installation, the small plastic part 74 is fixed on both sides of the clamping blocks 9 through the two L-shaped buckles 10, so that the firmness of the small plastic part 74 is higher during use.

[0026] Further improvement is that the bottom of the limiting groove 12 is provided with an outwardly protruding positioning column 13, the middle of the small plastic part 74 is provided with a positioning hole 11, and the positioning hole 11 of the assembled small plastic part 74 is sleeved on the positioning column 13.

[0027] After assembly, the positioning hole 11 of the assembled small plastic part 74 is sleeved on the positioning column 13, which can not only play a positioning role, but also play a limiting role when one side of the small plastic part 74 is deformed by extrusion, thereby avoiding the problem of falling of the L-shaped buckle 10 on the other side.

[0028] Further improvement is that the lock point 71 adopts a rivet structure, the lock block body 73 is provided with a rivet hole 8, and the rolling sleeve 72 is fixed in the rivet hole 8 through the lock point 71; the lock point 71 is provided with an eccentric shaft 6, and the relative position of the rolling sleeve 72 can be adjusted through the eccentric shaft 6.

[0029] The rolling sleeve 72 is fixed in the rivet hole 8 through the lock point 71, and the installation structure is simpler. During assembly, due to the unevenness of doors and windows and the thickness of the leather strip, the conventional lock point 71 rivet is prone to gaps after assembly, therefore, the eccentric shaft 6 structure is formed in the middle section of the lock point 71, after rotation of the eccentric shaft 6, the relative position of the rolling sleeve 72 can be adjusted, thereby solving the problem that the position of the rolling sleeve 72 cannot be adjusted when the doors and windows are uneven and the thickness of the leather strip changes.

[0030] The above embodiments are only the preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and substitutions made by those skilled in the art based on the present application shall fall within the scope of protection of the present application.
