Detailed Implementation

[0014] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0015] Example 1: As Figure 1 and 2 It includes: a plastic sleeve 1, two plastic sleeves 1 are symmetrically arranged on the left and right, a V-shaped base 4 is installed on the inner wall of the plastic sleeve 1, an upper hook 5 is provided above the V-shaped base 4, an installation hole 7 is opened on the inner wall of the upper hook 5, and the two sides of the upper hook 5 are the installation hole side 8. The installation hole side 8 and the inner wall of the plastic sleeve 1 are slidably installed with aluminum blocks 2. The aluminum blocks 2 are used to lift the upper hook 5 and control the plastic sleeve 1 to expand outward. The outward expansion of the plastic sleeve 1 squeezes and fixes the inside of the connected horizontal material 14 and vertical material 15.

[0016] The specific application scenario of this embodiment is as follows: the plastic sleeve 1 is symmetrically arranged on the left and right, and its inner wall is snapped with a V-shaped base 4. The upper hook 5 is provided above the V-shaped base 4. The mounting hole 7 on the inner wall of the upper hook 5 cooperates with the mounting hole side 8 on both sides. The aluminum block 2 is slidably installed between the mounting hole side 8 and the inner wall of the plastic sleeve 1. The upper hook 5 is lifted by the aluminum block 2, which can control the plastic sleeve 1 to expand outward, thereby squeezing the interior of the connected horizontal material 14 and vertical material 15, so as to realize the fixed connection between the horizontal material and the vertical material.

[0017] Example 2: Figure 1 and Figure 2 The inner wall of the plastic sleeve 1 has an aluminum block mounting position 10. The aluminum block 2 is stepped, wider at the bottom and narrower at the top. The bottom inner wall of the hook 5 has a groove 3. The outer wall of the plastic sleeve 1 has a plastic sleeve centering groove 11. The top outer wall of the aluminum block 2 and the inner wall of the groove 3 are fitted together to control the hook 5. The top two outer walls of the hook 5 are fixedly connected to the hook angle 6. The hook angle 6 extends through the side wall of the plastic sleeve 1 to the outside. The inner walls of the horizontal material 14 and the vertical material 15 have aluminum material mounting grooves 13. The hook angle 6 and the inner wall of the aluminum material mounting groove 13 are fitted together to be hooked together. The top of the V-shaped base 4 has a screw contact groove 12. The inner wall of the mounting hole 7 is threaded with a screw 9. The bottom of the screw 9 is fitted together with the inner wall of the screw contact groove 12 to be connected.

[0018] The specific application scenario of this embodiment is as follows: The aluminum block mounting position 10 on the inner wall of the plastic sleeve 1 is used to install the stepped aluminum block 2, which is wider at the bottom and narrower at the top. The groove 3 on the bottom inner wall of the hook 5 is inserted into the top outer wall of the aluminum block 2 to control the movement of the hook 5. The hook angles 6 on both sides of the top of the hook 5 extend through the side wall of the plastic sleeve 1 to the outside and are engaged with the aluminum mounting grooves 13 on the inner wall of the horizontal material 14 and the vertical material 15. At the same time, the screw 9 in the mounting hole 7 is engaged with the screw abutment groove 12 on the top of the V-shaped base 4. By tightening the screw 9, the relevant components can be pushed to move together, further strengthening the connection stability between the hook angle 6 and the aluminum mounting groove 13, and finally achieving a firm connection between the horizontal material and the vertical material. The groove 11 in the plastic sleeve is used to cooperate in extruding the horizontal material 14 and the vertical material 15.

[0019] The working principle of this utility model is as follows: When used by those skilled in the art, the plastic sleeve 1, which is symmetrically arranged on the left and right, serves as the basic support structure. A V-shaped base 4 is snapped into the inside of the plastic sleeve 1, providing support for the overall structure. An aluminum block 2 is installed in the aluminum block mounting position 10 on the inner wall of the plastic sleeve 1. Utilizing its stepped, wider-than-narrower structure, it engages with the groove 3 on the bottom inner wall of the upper hook 5, forming a foundation for lifting and controlling the rear hook 5. The upper hook 5, as the core transmission component, has its two upper hook angles 6 extending through the side wall of the plastic sleeve 1 to the outside, forming a preliminary connection with the aluminum mounting grooves 13 on the inner walls of the horizontal and vertical materials 14, thus achieving the connection between the horizontal and vertical materials. When the screw 9 is tightened through the mounting hole 7, the bottom of the screw 9 contacts the screw abutment groove 12 on the top of the V-shaped base 4 and generates a thrust, which pushes the hook 5 and the aluminum block 2 to move together: the aluminum block 2 lifts the hook 5, so that the hook angle 6 is further inserted into the aluminum material mounting groove 13 and the hanging force is enhanced; at the same time, the plastic sleeve 1 expands outward under the action of the internal components, and squeezes the inner walls of the horizontal material 14 and the vertical material 15. Finally, through the lifting transmission of the aluminum block 2, the tightening thrust of the screw 9, the hanging of the hook angle 6 and the aluminum material mounting groove 13, and the expansion and squeezing of the plastic sleeve 1, multiple forces work together to achieve a stable and firm connection between the horizontal material 14 and the vertical material 15.
