DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings.

[0022] A glue-injected inner connector for a center support is installed in a snap-fit ​​groove 1-1 of the center support 1, and is used to make a transition connection between the center support 1 and an external component 2. The external component 2 can be a center support or an outer frame. The center support inner connector includes a snap-fit ​​component 3 and an auxiliary component 4. The auxiliary component 4 can be swingably installed on the snap-fit ​​component 3. The spacing between the ends of the snap-fit ​​component 3 and the auxiliary component 4 can be changed by swinging the auxiliary component 4. During installation, the spacing between the ends of the snap-fit ​​component 3 and the auxiliary component 4 is reduced so that the snap-fit ​​component 3 and the auxiliary component 4 extend into the snap-fit ​​groove 1-1, and then the auxiliary component 4 is adjusted so that the snap-fit ​​component 3 and the auxiliary component 4 are snap-fitted with the snap-fit ​​groove 1-1 respectively, thereby realizing the connection between the center support inner connector and the center support 1. The snap-fit ​​component 3, the auxiliary component 4, and the snap-fit ​​groove 1-1 together form a glue injection cavity 5. After the center support inner connector is installed, glue is injected into the glue injection cavity 5.

[0023] By adjusting the auxiliary part 4 to change the width of the end of the middle brace inner connector, it is convenient to insert the middle brace inner connector into the buckle groove 1-1, and there is no need to install the middle brace inner connector from both ends of the profile, thereby improving the installation convenience of the middle brace inner connector. At the same time, by injecting glue into the glue injection cavity 5 to maintain the position of the buckle 3 and the auxiliary part 4, it is ensured that the buckle 3 and the auxiliary part 4 can be stably connected to the buckle groove 1-1, thereby improving the assembly stability of the middle brace inner connector.

[0024] A buckle plate 3-8 is provided at the bottom of the buckle 3, and a first groove 3-9 is provided on the buckle plate 3-8, so that a first hooking portion 3-4 is formed at the bottom of the buckle plate 3-8, and the first hooking portion 3-4 is hooked with an inner wall of one side of the buckling groove 1-1.

[0025] A mounting groove 3-1 is provided at the bottom of the fastener 3, so that the fastening plate 3-8 and the auxiliary component 4 are both arranged at the bottom of the fastener 3, and an opening groove 3-3 is provided on one side of the mounting groove 3-1. One end of the auxiliary component 4 is swingably mounted on the fastener 3 through the mounting groove 3-1, and the other end of the auxiliary component 4 extends out of the mounting groove 3-1 through the opening groove 3-3.

[0026] The auxiliary component 4 includes a rotating shaft 4-2 and an auxiliary plate 4-3 connected to the rotating shaft. The rotating shaft 4-2 is installed in the mounting groove 3-1 so that the auxiliary component 4 can be swingably connected to the mounting groove 3-1. The auxiliary plate 4-3 extends out of the mounting groove 3-1 through the opening groove 3-3. A second groove 4-4 is provided on the auxiliary plate 4-3, thereby forming a second hooking portion 4-1 at the bottom of the auxiliary plate 4-3, and the second hooking portion 4-1 is hooked with the inner wall on the other side of the snap-fit ​​groove 1-1.

[0027] The auxiliary member 4 is swung to change the distance between the first hooking portion 3-4 and the second hooking portion 4-1, thereby facilitating the installation of the middle support inner connecting member into the buckling groove 1-1.

[0028] As a preferred embodiment, to ensure that the auxiliary component 4 has a larger swing amplitude, the inner diameter of the mounting groove 3-1 is larger than the diameter of the rotating shaft 4-2, and the width of the opening groove 3-3 is larger than the thickness of the auxiliary plate 4-3 and smaller than the diameter of the rotating shaft 4-2.

[0029] A top screw 6 is installed on the fastening part 3 through a thread. During the rotation of the top screw 6, the auxiliary part 4 is first opened so that the auxiliary part 4 is hooked with the fastening groove 1-1. As the top screw 6 continues to rotate, the top screw 6 abuts against the middle support 1, thereby locking the inner connecting part of the middle support on the middle support 1.

[0030] The fastener 3 is provided with a mounting through hole 3-5 and a threaded hole 3-2, a top screw 6 is installed in the threaded hole 3-2, the mounting through hole 3-5 and the threaded hole 3-2 are coaxially arranged, and the top screw 6 is adjusted through the mounting through hole 3-5.

[0031] The fastener 3 is a hollow part, and a reinforcing rib 3-6 is provided in the middle of the fastener 3. A connecting cavity 3-7 is formed between the reinforcing rib 3-6 and the inner wall of the fastener 3, so as to connect the external component 2 and the fastener 3 through the connecting cavity 3-7, thereby improving the installation stability of the subsequent external component 2. A through hole is also provided on the reinforcing rib 3-6, so that a hexagonal wrench can pass through the installation through hole 3-5 and the through hole to adjust the top screw 6.

[0032] A hexagonal groove is provided at the upper end of the top screw 6 to facilitate the hexagonal wrench to rotate the top screw 6, and a butt joint 6-1 is provided at the lower end of the top screw 6. The diameter of the butt joint 6-1 is smaller than the diameter of the fixing screw 2, which facilitates the connection between the butt joint 6-1 and the middle support 1.
