[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0032] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] Example 1, as Figures 1 to 4 The diagram shows the preferred embodiment of this utility model: a cabinet, including a cabinet body 2 and a door that can be opened relative to the cabinet body 2. Tracks 3 are provided at the top and bottom of the cabinet body 2, and the tracks 3 are arranged along the width direction of the cabinet body 2. The aforementioned slidable and rotatable mounting bracket 1 is movably arranged within the tracks 3. Specifically, there are four tracks 3, arranged in pairs at the top and bottom of the cabinet body 2, ensuring that the mounting bracket 1 can slide stably along the tracks 3.

[0035] Mounting bracket 1 includes a left frame 11 and a right frame 12 that are slidably disposed within the cabinet. The left frame 11 is provided with detachable electronic components 13. The left frame 11 and the right frame 12 are rotatably connected. After the left frame 11 and the right frame 12 slide out of the cabinet, the left frame 11 is rotated to move the mounting bracket 1 out of the cabinet.

[0036] Furthermore, the upper and lower ends of the left frame 11 and the right frame 12 are detachably connected to pulley assemblies 14, which cooperate with the rail 3. When maintenance is required inside the cabinet, the mounting bracket 1 is pulled outward from inside the cabinet 2 along the rail 3 until it moves close to the end of the rail 3. At this point, the left frame 11 is removed from the pulley assembly 14. The left frame 11 can then rotate relative to the right frame 12. Flipping the left frame 11 allows it to be removed from inside the cabinet 2, exposing the space inside the cabinet 2. This facilitates the modification of components inside the cabinet 2 by staff, and even allows staff to enter the cabinet 2, providing ample maintenance space for the cabinet in its confined space without the need to remove other electronic components.

[0037] Example 2, based on Example 1, such as Figures 5 to 9 As shown, both the right frame 12 and the left frame 11 include an upper support 111, a lower support 112, and a side support 113. The upper supports 111 of the right frame 12 and the left frame 11 are rotatably connected by a pin. The lower supports 112 of the right frame 12 and the left frame 11 are rotatably connected. The upper and lower ends of the side support 113 are detachably connected to the pulley assembly 14. The left frame 11 can be moved out of the cabinet 2 simply by removing the side support 113 from the pulley assembly 14.

[0038] In Example 3, based on Example 2, the pulley assembly 14 connected to the right frame 12 includes a connecting seat 141, on which a pulley 142 is rotatably connected. The connecting seat 141 has a connecting pipe 143. The connecting pipe 143 is inserted into the side bracket 113 of the right frame 12 and connected to the side bracket 113. Since the height of the right frame 12 needs to be finely adjusted during installation, the connecting pipe 143 is inserted into the side bracket 113. The connecting pipe 143 can be adjusted to an appropriate height, and after adjustment, it is screwed into the threaded post on the side bracket 113, thereby achieving the connection between the pulley assembly 14 and the right frame 12.

[0039] Meanwhile, the pulley assembly 14 connected to the left frame 11 includes a connecting seat 141, on which a pulley 142 is rotatably connected. The connecting seat 141 has a connecting plate 144, which is detachably connected to the side bracket 113 of the left frame 11. The connecting plate 144 is a U-shaped plate and has a waist-shaped hole. The connecting plate 144 is aligned with the side, and the position of the left frame 11 can be adjusted through the waist-shaped hole to adjust the left frame 11 to the same height as the right frame 12, and then it is fastened by a wing nut and a locking pin.

[0040] In Example 4, based on Example 3, a horizontal support 114 and a vertical support 115 are further provided between the upper support 111, lower support 112, and side support 113 of the left frame 11. Electronic components 113 are mounted on the horizontal and vertical supports 115, and when in the cabinet, the electronic components 113 are arranged along the length of the cabinet 2. When the left frame 11 is removed from the cabinet 2, the electronic components 113 are arranged along the width of the cabinet 2. This allows for direct exposure of the space behind the electronic components 113, enabling maintenance and repair of the interior of the cabinet 2 without removing the electronic components 113 from the mounting bracket 1.

[0041] In Example 5, based on Example 4, a positioning hole 31 is provided at the end of the track 3. A locking pin is inserted into the positioning hole 31 to restrict the sliding of the side bracket 113 of the right frame 12 located at the end of the track 3. After the left frame 11 is removed from the cabinet 2, in order to prevent the right frame 12 from moving during maintenance, the locking pin 116 can be removed from the side bracket 113 and inserted into the positioning hole 31. The locking pin 116 can abut against the right frame 12 to prevent it from sliding back and forth on the track 3 due to tilting angle or other reasons.

[0042] Furthermore, a locking plate 32 is also connected to the bottom of the cabinet 2. The locking plate 32 is removed from the cabinet 2 and installed on the track 3. The locking plate 32 contacts the side bracket of the right frame 12 to restrict the rotation of the right frame 12. This locks the angle of the mounting bracket 1, preventing the mounting bracket from flipping around its axis.

[0043] In summary, the sliding and flip-up mounting bracket and cabinet of this utility model allow the mounting bracket to be moved out of the cabinet by sliding and flipping inside the cabinet, which facilitates the installation and maintenance of electronic components inside the cabinet.

[0044] The above description is based on the preferred embodiments of this utility model. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
