Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example

[0030] Reference Figures 1 to 8 , is an embodiment of the utility model, which provides a compact self-locking fastening ring network cabinet, including,

[0031] The ring main unit 100 comprises a cabinet body 101, a cabinet foot 102 fixedly mounted on the bottom surface of the cabinet body 101, a cabinet door 103 hinged to the cabinet body 101, and a handle 104 fixedly mounted on one side of the outer surface of the cabinet door 103;

[0032] In addition, there are a heat dissipation component 200 fixedly installed on the upper outer surface of the cabinet 101, a bracket component 300 fixedly installed on one side of the inner surface of the cabinet 101, a lock component 400 installed on the bracket component 300, an installation component 500 installed on the lock component 400, a line inlet component 600 fixedly installed on the bottom of the cabinet 101 and connected to the cabinet 101, and a branch line component 700 fixedly installed in the inner cavity of the cabinet 101 and fixedly connected to both sides of the inner surface of the cabinet 101.

[0033] Specifically, the heat dissipation assembly 200 includes a waterproof cover 201 fixedly installed on the outer surface of the cabinet body, a dustproof net 202 fixedly installed on the bottom surface of the waterproof cover 201, a fan rack 203 fixedly installed on the inner surface of the cabinet body 101, and a fan 204 fixedly installed on the fan rack 203.

[0034] Furthermore, the rack assembly 300 includes a vertical frame 301 fixedly mounted on the inner surface of the cabinet 101 , a limiting hole 302 provided on the vertical frame 301 , a horizontal frame 303 mounted on the vertical frame 301 , and a limiting groove 304 provided on the edge of the horizontal frame 303 .

[0035] Specifically, the locking assembly 400 includes a buckle 401 mounted on the cross frame 303, a guide rod 402 slidably connected to the buckle 401, a spring 403 mounted on the outer surface of the guide rod 402, a limiting column 404 fixedly connected to the guide rod 402, a pushing column 405 fixedly arranged on the upper surface of the limiting column 404, a spring 406 stuck on one side of the pushing column 405, and a button 407 fixedly installed on the upper surface of the spring 406.

[0036] Specifically, the installation assembly 500 includes a fixing plate 501 fixedly installed on the buckle 401, a special-shaped shaft 502 passing through the fixing plate 501, a fixing block 503 fixedly installed on the fixing plate 501, a pull rod 504 passing through the fixing block 503, a spring 505 sleeved on the outer surface of the pull rod 504, and a blocking block 506 fixedly connected to one end of the pull rod 504.

[0037] Specifically, the line inlet assembly 600 includes a fixing seat 601 fixedly mounted on the outer surface of the bottom of the cabinet 101 , a fixing card 602 mounted on the fixing seat 601 , and a protective ring 603 disposed in the inner cavity of the fixing card 602 .

[0038] Preferably, the branching assembly 700 includes a fixing rod 701 fixedly mounted on the inner surface of the cabinet 101 , and a line card 702 fixedly mounted on the fixing rod 701 .

[0039] When in use, the bus is passed through the line inlet component 600, through the branch line component 700, and the cables corresponding to each device are respectively clamped in the corresponding line card 702. When installing the device, you only need to insert the special-shaped shaft 502 into the mounting hole of the device, and then insert it into the inner cavity of the fixing plate 501. Passing through the inner cavity of the fixing plate 501 will push the blocking block 506 to move upward. Due to the downward thrust of the spring 2 505, the blocking block 506 will slide into the groove of the special-shaped shaft 502, thereby fixing the special-shaped shaft 502 so that it cannot be pulled out. If you want to adjust the position of the device, you can press the button 407, and the spring piece 406 will push the limiting groove 304 where the limiting column 404 is located, so that the entire locking assembly 400 can be moved on the horizontal frame 303, thereby adjusting the horizontal position of the device, and the vertical position can be adjusted by adjusting the different limiting holes 302 of the horizontal frame 303 on the vertical frame 301.

[0040] In summary, the special-shaped shaft 502 is inserted into the fixing plate 501 and then locked by the blocking block 506. This is faster and more convenient than the traditional bolt connection and is not easy to become loose over time. Because the size of the equipment is different, it is also very convenient to adjust the position of the equipment. For lateral adjustment, you only need to press the button 407 to move the equipment on the horizontal frame 303 with the locking assembly 400. Release the button 407 to fix the equipment, which is very convenient.
