[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] 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.

[0037] Example 1, reference Figure 1 , Figure 2 and Figure 3, which is the first embodiment of the present invention, and provides a transmission and distribution motor cabinet with a fixed structure, in order to solve the problem that sometimes the cabinet door 600 is directly put on without checking whether it is closed, resulting in the situation that it is not closed tightly, and dust will enter the components in the cabinet, causing the internal components to short-circuit, thereby affecting the normal use. It includes a base 100, a buried base 200 under the base 100, and a motor cabinet 300 vertically fixed on the top of the base 100, a cabinet door 600 is hinged on one side of the motor cabinet 300 for closing the motor cabinet 300, a switch assembly 700 is fixed on one side of the middle of the cabinet door 600, and a limit assembly 800 is fixed on the inner side of the motor cabinet 300 at the position corresponding to the switch assembly 700;

[0038] Among them, the limiting component 800 includes a fixed shell 801 fixed at the inner side of the motor cabinet 300, which is used for the installation and protection of components. The inner side of the fixed shell 801 is evenly distributed with movable holes 802 around the semi-arc-shaped fixed block 708, which is used to fix the elastic telescopic rod 803. The elastic telescopic rod 803 is fixed on the inner side of the movable hole 802, and a clamping block 804 for limiting the semi-arc-shaped fixed block 708 is fixed at the end of the elastic telescopic rod 803; the switch component 700 is inserted into the clamping block 804 for closing the cabinet door 600.

[0039] When in use, when the cabinet door 600 rotates toward the motor cabinet 300, the switch assembly 700 contacts the block 804, the switch assembly 700 squeezes the block 804, and the elastic telescopic rod 803 retracts and retracts. After the switch assembly 700 passes through the block 804, the block 804 returns to its original position under the elastic reset of the elastic telescopic rod 803, so that the block 804 plays the role of limiting the switch assembly 700, thereby firmly fixing the cabinet door 600 on the motor cabinet 300, and the cabinet door 600 will not be opened due to personal negligence.

[0040] Furthermore, the switch assembly 700 includes a fixed seat 701 fixed to one side of the middle of the cabinet door 600, a rotating block 702 is hinged on the fixed seat 701, a handle 703 is vertically fixed to the middle of the bottom end of the rotating block 702, and the handle 703 is used to rotate the rotating block 702. A moving groove 704 is opened between the fixed seat 701 on one side of the middle of the cabinet door 600. The size of the moving groove 704 is larger than the size of the rotating block 702, which is convenient for the entry of the rotating block 702. A limiting groove 705 for limiting the movement of the rotating block 702 is opened on the fixed seat 701 and the moving groove 704. After the rotating block 702 rotates, it enters the moving groove 704 through the limiting groove 705. The interior of the cabinet door 600 is connected with a corresponding fixed seat 701 through a sliding connection. 01, the use of the moving rod 706 facilitates the fixation of the semi-arc fixed block 708 and the sliding setting of the semi-arc moving block 709, a return spring 707 is connected between the outer side of the moving rod 706 and the inner side of the cabinet door 600, so that the moving rod 706 can return to its original position after use, and a semi-arc fixed block 708 is vertically fixed at one end of the moving rod 706 away from the rotating block 702, which is used to push open the card block 804, and a semi-arc moving block 709 with a limiting block is slidably connected to the outer side of the moving rod 706 near the semi-arc fixed block 708. The contact between the semi-arc moving block 709 and the semi-arc fixed block 708 can release the restriction of the semi-arc fixed block 708 on the card block 804.

[0041] Furthermore, a protrusion is fixed on one end of the upper portion of the fixing seat 701 close to the moving groove 704 , which can increase the contact length of the fixing seat 701 , and a notch is provided at a corresponding position on the upper portion of the moving rod 706 .

[0042] Furthermore, a lock for limiting the rotation of the rotating block 702 is provided on the limiting groove 705 to facilitate locking and fixing.

[0043] Example 2, reference Figures 1 to 7 , which is the second embodiment of the present invention, is different from the previous embodiment in that it aims to solve the problem of inconvenient installation of the power transmission and distribution cabinet. This embodiment provides a base 100 with bayonet holes 101 on both sides, and a fastening component 400 for clamping the bayonet holes 101 is provided in the buried base 200.

[0044] The base 100 is directly placed on the buried base 200 , and the fastening assembly 400 is directly clamped on the bayonet 101 , which is convenient for installation and fixation.

[0045] Furthermore, the fastening assembly 400 includes a placement groove 401 opened in the buried base 200 to facilitate the placement of other components. A U-shaped connecting plate 402 is slidably connected inside the placement groove 401. Slots 403 are symmetrically opened in the middle of both sides of the U-shaped connecting plate 402 for connecting the middle rotating plate 406. An extrusion spring 404 is vertically fixed to the middle of the top of the U-shaped connecting plate 402 for restoring the position of the top column 405. A top column 405 is fixed to the top of the extrusion spring 404. Middle rotating plates 406 are connected between the two sides of the lower part of the top column 405 and the slot 403. The middle part of the middle rotating plate 406 is connected to the placement groove 401 through a rotating shaft. Buckles 407 are hinged on both sides of the top of the buried base 200. The top of the buckle 407 is stuck in the bayonet 101. A connecting plate 408 is connected between one side of the middle of the buckle 407 and the top of the U-shaped connecting plate 402.

[0046] When in use, the top column 405 is pressed downward, and the top column 405 squeezes the squeezing spring 404, thereby driving the U-shaped connecting plate 402 to move downward. The downward movement of the U-shaped connecting plate 402 drives the middle rotating plate 406 to be restricted on both sides of the placement groove 401 and the lower part of the top column 405, so that the top sides of the U-shaped connecting plate 402 move upward. The upward movement of the top sides of the U-shaped connecting plate 402 drives the buckle 407 to rotate into the bayonet 101 through the connecting plate 408, thereby firmly clamping the buckle 407 in the bayonet 101, and the purpose of clamping is achieved by the weight of the base 100 itself.

[0047] Furthermore, a placement groove is provided in the middle of the top of the top column 405 to facilitate the placement of the middle rotating plate 406.

[0048] Furthermore, a cylinder 500 in contact with the placement groove is vertically fixed in the middle of the bottom end of the base 100, so as to increase the length of the bottom end of the base 100 and facilitate the use of top columns 405 of different heights.

[0049] Furthermore, the limiting assembly 800 also includes a button 805 arranged at one end of the inner side of the fixed shell 801, and the output end of the button 805 is connected to the input end of the cylinder 500 to facilitate the control of the cylinder 500. The button 805 and the cylinder 500 can be powered by an external power source, such as a battery.

[0050] Furthermore, a heat dissipation window is provided inside the motor cabinet 300, and a heat conduction plate is built in the heat dissipation window. The temperature inside the motor cabinet 300 is conducted to the heat dissipation window through the heat conduction plate, and heat is dissipated through the heat dissipation window.

[0051] The rest of the structure is the same as that of Example 1.

[0052] Working principle: During installation, the base 100 is directly placed on the buried base 200, and the buckle 407 is aligned with the bayonet 101. At this time, the cylinder 500 contacts the top column 405 and presses the top column 405 downward. The top column 405 squeezes the squeezing spring 404 at the same time, thereby driving the U-shaped connecting plate 402 to move downward. The downward movement of the U-shaped connecting plate 402 drives and the middle rotating plate 406 is restricted on both sides of the placement groove 401 and the lower part of the top column 405, so that the top two sides of the U-shaped connecting plate 402 move upward. The upward movement of the top two sides of the U-shaped connecting plate 402 drives the buckle 407 to rotate into the bayonet 101 through the connecting plate 408, thereby firmly clamping the buckle 407 in the bayonet 101;

[0053] When the engineer closes the cabinet door 600, when the cabinet door 600 rotates toward the motor cabinet 300, the semi-arc fixed block 708 contacts the block 804, the semi-arc fixed block 708 squeezes the block 804, and the elastic telescopic rod 803 is retracted. When the semi-arc fixed block 708 passes through the block 804, the block 804 is stuck between the semi-arc fixed block 708 and the semi-arc moving block 709, and the block 804 prevents the semi-arc fixed block 708 from moving back, so that the block 804 plays a role in limiting the semi-arc fixed block 708, so that the cabinet door 600 is closed on the motor cabinet 300, and the cabinet door 600 will not be closed due to personal negligence. When opening, turn the handle 703 to make the rotating block 702 move in The rotating block 702 rotates around the fixed seat 701, and contacts and squeezes the moving rod 706 when rotating, and the moving rod 706 drives the semi-arc moving block 709 to move toward the block 804 and pass through the block 804. When the handle 703 is no longer rotated, the moving rod 706 is driven to move outward under the elastic reset of the reset spring 707, and the block 804 contacts the semi-arc moving block 709 so that the semi-arc moving block 709 moves toward the semi-arc fixed block 708 on the moving rod 706. The semi-arc fixed block 708 and the semi-arc moving block 709 form an ellipsoid shape, so that the block 804 slides over the semi-arc fixed block 708 and the semi-arc moving block 709, and the semi-arc fixed block 708 returns to the initial position;

[0054] When disassembly is required, the handle 703 is rotated to the same horizontal position as the fixing seat 701, and the rotating block 702 is moved toward the limit groove 705, thereby increasing the moving distance of the moving rod 706, making the semi-arc-shaped fixing block 708 contact with the button 805, and causing the cylinder 500 to retract. After the cylinder 500 retracts, the top column 405 is no longer restricted, and the top column 405 is driven to move upward through the elastic recovery of the extrusion spring 404, thereby driving the U-shaped connecting plate 402 to move upward. The upward movement of the U-shaped connecting plate 402 and the restriction of the middle rotating plate 406 on both sides of the placement groove 401 and the lower part of the top column 405 cause the top two sides of the U-shaped connecting plate 402 to move downward. The downward movement of the top two sides of the U-shaped connecting plate 402 drives the buckle 407 to rotate outward of the bayonet 101 through the connecting plate 408, thereby disengaging the buckle 407 from the bayonet 101.
