[0026] In order to make the above-mentioned purposes, 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.

[0027] 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.

[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 Figure 1-Figure 7 The embodiment provides a strong heat dissipation power distribution control cabinet, including a cabinet body 1; a drawer structure is slidably provided at the middle and lower part of the cabinet body 1, and a heat dissipation fan 2 is installed in the drawer structure. The drawer-type structure allows the user to quickly extract or insert the drawer unit with the heat dissipation fan 2 without opening the cabinet body 1 in a large area or interrupting the operation of the entire system, which is convenient for maintaining, cleaning or replacing a certain component separately; the drawer structure includes a mounting portion for mounting the heat dissipation fan 2 and a limit plate 3 fixedly connected to the mounting portion, such as Figure 1As shown, the length and width of the cross section of the limiting plate 3 are greater than the length and width of the installation portion. By setting the limiting plate 3, when the cooling fan 2 is installed, the limiting plate 3 contacts the cabinet 1, which plays a role in limiting the drawer;

[0031] Reference Figure 1 The cabinet 1 is provided with a locking component for locking the drawer structure. The locking components are symmetrically arranged in two groups. A single locking component may be worn, damaged or fail, and the two groups of locking components can be used as a redundant guarantee. Even if one group of locking components fails, the other group of locking components can still maintain the locking function, thereby extending the service life of the overall locking system;

[0032] Reference Figure 6 The locking component includes a fixing ring 4 fixedly connected to the cabinet body 1, the fixing ring 4 has a through hole 5, the through hole 5 is arranged along the width direction of the cabinet body 1, the drawer structure is arranged along the thickness direction of the cabinet body 1, the through hole 5 is elastically slidably connected with a locking block 6, and the locking block 6 has a curved surface 7 on the side facing the limiting plate 3;

[0033] During use, when the cooling fan 2 needs to be repaired, the drawer structure is pulled out of the cabinet 1. After the repair is completed, the drawer structure is pushed back into the cabinet 1. During this process, the limit plate 3 contacts the arc surface 7 of the locking block 6 and squeezes the arc surface 7, so that the locking block 6 is away from the cabinet 1. When the drawer structure completely enters the cabinet 1, the locking block 6 returns to its original position under the action of elastic force, so that the locking block 6 overlaps with the limit plate 3, and the overlapping part is a plane. Even if the drawer structure tends to move outward, the locking block 6 will not move because the overlapping part is a plane, thereby achieving a quick locking effect.

[0034] As a preferred embodiment of the present invention, refer to Figure 2-Figure 6 The locking component also includes a transition rod 8 fixedly connected to the locking block 6, the cross section of the transition rod 8 is smaller than the cross section of the locking block 6, and a connecting plate 9 fixedly connected to the side of the fixing ring 4 away from the cabinet 1, and the end of the transition rod 8 away from the locking block 6 passes through the connecting plate 9, and the transition rod 8 is sleeved with a spring 10, and the two ends of the spring 10 are respectively in contact with the connecting plate 9 and the locking block 6;

[0035] A baffle 11 is fixed to one end of the transition rod 8 away from the locking block 6. The cross-sectional area of ​​the baffle 11 is larger than the cross-sectional area of ​​the opening of the connecting plate 9. Under the elastic force of the spring 10, the baffle 11 contacts the connecting plate 9, and the arc surface 7 protrudes from the through hole 5.

[0036] The locking component also includes a guide block 12 fixedly connected to the fixing ring 4, and the guide block 12 has a guide hole 13;

[0037] Also includes unlocking components, refer to Figure 1-Figure 3The unlocking component includes an operating rope 14, an end of the operating rope 14 passes through a guide hole 13 and then is connected to the connecting plate 9, and the guide hole 13 is arranged along the width direction of the cabinet 1;

[0038] When the drawer mechanism is in use, the limit plate 3 contacts and squeezes the curved surface 7 during the process of returning to the cabinet 1, so that the locking block 6, the transition rod 8 and the baffle 11 are all away from the cabinet 1. The operating rope 14 is made of a flexible material and will not affect the movement of the above components.

[0039] After the drawer mechanism is installed in place, under the elastic force of the spring 10, the locking block 6, the transition rod 8 and the baffle 11 return to their initial positions, and the locking block 6 blocks the limit plate 3 to fix the drawer structure. When the locking component needs to be unlocked, the middle part of the connecting rope is pulled downward. Since the connecting rope passes through the guide hole 13 of the guide hole 13 and the connecting rope is made of flexible material, it can drive the locking block 6, the transition rod 8 and the baffle 11 away from the cabinet body 1. When the locking block 6 does not overlap with the limit plate 3, the drawer structure can be pulled out, which is convenient to use.

[0040] As a preferred embodiment of the present invention, refer to Figure 5 The cooling fan 2 is connected to a plug 15 via a quick-release connector, and the plug 15 is installed on the side of the installation portion facing the cabinet 1; a socket 16 matching the plug 15 is provided inside the cabinet 1;

[0041] When in use, the cooling fan 2 is connected to the plug 15 via a quick-release connector, and the cooling fan 2 can be quickly separated from the plug 15. When the drawer structure is pushed into the cabinet 1, the plug 15 can be inserted into the socket 16, which automatically supplies power to the cooling fan 2, making it more convenient to use.

[0042] As a preferred solution of the present invention, the limit plate 3 is provided with a handle 17. The limit plate 3 can be pushed or pulled by holding the handle 17, so that the limit plate 3 can be more conveniently subjected to force.
