Detailed Implementation

[0023] 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.

[0024] Example 1: As Figures 1-4 ,include:

[0025] The rear fixing member 1 is fitted with a straight panel 3 at its top and a front fixing member 2 at its head. A first fastening screw hole 5 is provided at the connection between the top of the front fixing member 2 and the rear fixing member 1, and a first screw 19 is installed in the first fastening screw hole 5.

[0026] The rear fixing component 1 and the inner wall of the straight panel 3 are provided with a second fastening screw hole 6. The inner wall of the second fastening screw hole 6 is fitted with a second screw 15. The bottom of the first screw 19 and the second screw 15 are fitted with the inner wall of the cabinet for fixed connection.

[0027] The specific application scenario of this embodiment is as follows: The rear fixing component 1, the straight panel 3, and the front fixing component 2 constitute the basic frame structure. The straight panel 3 is installed on the top of the rear fixing component 1 through a snap-fit ​​method, and the front fixing component 2 is snapped onto the head end of the straight panel 3. This connection method facilitates quick assembly and disassembly of the components. The first fastening screw hole 5 and the second fastening screw hole 6 opened at the connection point, together with the first screw 19 and the second screw 15, firmly fix the entire frame to the inner wall of the cabinet. The screw fastening method provides reliable connection strength, ensuring that the frame will not easily loosen in the cabinet. In actual use, when it is necessary to install the internal structure of the cabinet, first place the rear fixing component 1 in a suitable position, snap on the straight panel 3, and then install the front fixing component 2. By tightening the first screw 19 and the second screw 15, the entire frame is stably fixed to the inner wall of the cabinet, providing stable support for the installation and use of other components inside the cabinet. It is not necessary to drill pre-embedded holes in the cabinet to complete the fixed installation between the straight panel 3 and the cabinet, which improves the speed of installation and the convenience of operation.

[0028] Example 2: Figure 1 and Figure 2 The top outer wall of the panel 3 is fitted with an arm 4. The head end of the arm 4 engages with the inner rear wall of the front fixing member 2. The top side wall of the panel 3 has a groove, and the inner wall of the groove is slidably connected to the first connecting arm 7 via a pin. The top of the panel 3 has a crescent-shaped adjusting block 8. The top inner wall of the arm 4 is threaded with an adjusting cam screw 9. The bottom end of the adjusting cam screw 9 has a spiral groove, which engages with the inner wall of the crescent-shaped adjusting block 8. The end of the first connecting arm 7 is rotatably connected to the main beam 10 via a pin. The side wall of the main beam 10 is rotatably connected to the second connecting arm 10 via a pin. Arm 11, the end of the second connecting arm 11 is rotatably connected to the cylinder mounting base 12 via a shaft pin, the end of arm 4 is rotatably connected to the head end of the second connecting arm 11 via a shaft pin, the end of the main beam 10 is rotatably connected to the inner wall of the cylinder mounting base 12, the inner wall of the cylinder mounting base 12 is fixedly installed with a spring sleeve 13 and a spring fixing block 14, a spring 16 is installed between the spring sleeve 13 and the spring fixing block 14, the spring 16 has a cylinder inside, the outer side of the spring sleeve 13 has a cam 17, the cam 17 is rotatably connected to the inner wall of the cylinder mounting base 12, and the end of the cylinder mounting base 12 has a cup head 18.

[0029] The specific application scenario of this embodiment is as follows: The components such as the straight panel 3, arm 4, first connecting arm 7, main beam 10, second connecting arm 11, and cylinder fixing seat 12 together constitute an adjustable mechanical structure. The top of the straight panel 3 is snapped onto the mounting arm 4, which is snapped onto the inner wall of the rear end of the front fixing part 2 to form the structural foundation. The sliding groove on the straight panel 3 is slidably connected to the first connecting arm 7 through a shaft pin, allowing the first connecting arm 7 to slide within the sliding groove and achieve position adjustment. The cooperation between the crescent-shaped adjusting block 8 and the adjusting cam screw 9 is the key to realizing the adjustment function. The spiral groove at the bottom of the adjusting cam screw 9 is snapped onto the inner wall of the crescent-shaped adjusting block 8. When the adjusting cam screw 9 is rotated, the interaction between the spiral groove and the crescent-shaped adjusting block 8 drives the first connecting arm 7 to slide within the sliding groove, thereby changing the shape of the entire structure. The main beam 10, the second connecting arm 11, and the cylinder fixing seat 12 are rotatably connected through a shaft pin to form a multi-link structure, which can achieve flexible movement and angle adjustment. The spring assembly, consisting of spring sleeve 13, spring fixing block 14, and spring 16, along with the internal hydraulic cylinder and external cam 17, further enhances the structure's adjustability and stability. Spring 16 provides buffering and restoring force; when the structure is subjected to external force, the spring compresses to absorb energy, and returns to its original position after the external force disappears. Cam 17 is rotatably connected to the inner wall of hydraulic cylinder fixing seat 12. By rotating cam 17, the force applied to spring sleeve 13 can be changed, thereby adjusting the compression degree of spring 16 and the tension of the entire structure. The two outer walls of cup head 18 are fixedly connected to the inner wall of the cabinet with screws, thus completing the quick installation of the hinge.

[0030] The working principle of this utility model is as follows: When used by those skilled in the art, the basic frame is constructed using the rear fixing component 1, the straight panel 3, and the front fixing component 2. A combination of snap-fit ​​and screw fastening is employed. The snap-fit ​​facilitates quick assembly and disassembly. The first fastening screw hole 5 and the second fastening screw hole 6, in conjunction with the first screw 19 and the second screw 15, firmly fix the frame to the inner wall of the cabinet, avoiding the need for pre-drilled holes, improving installation efficiency and convenience, and providing stable support for other components inside the cabinet. This design concept provides a reliable and efficient fixing solution for the construction of the cabinet's internal structure, ensuring the stability and integrity of the cabinet's internal structure.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
