DETAILED DESCRIPTION

[0021] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0022] See also Figure 1-7 The utility model provides an embodiment: a low-voltage withdrawable switch cabinet, including a cabinet body 1, and a heat dissipation component 4 is also provided at the bottom of the cabinet body 1; the heat dissipation component 4 includes a guide rail 41 and a slide rail 42 slidably installed on the guide rail 41, and a fan 40 is fixed on the slide rail 42 by a fastener.

[0023] In summary, since the fan 40 can slide at the bottom of the cabinet 1, it is convenient to assemble the fan 40 and remove the fan 40, solving the problem of inconvenient fan maintenance caused by the fan being installed on the cabinet in the prior art. Based on this, although the device has a simple structure, it is easy to use, reduces the difficulty of maintenance, and has great flexibility.

[0024] Furthermore, since the bottom of the cabinet 1 is fixed to the ground by a base 3, the base 3 can be used to support the cabinet 1 to avoid contact between the cabinet 1 and the ground, which would cause the cabinet 1 to be corroded and have a short life. At the same time, the elevated cabinet 1 is also conducive to air flow and reduces moisture damage to the cabinet 1.

[0025] Furthermore, since the side of the base 3 facing the ground is an open structure, there can be enough space between the base 3 and the ground to facilitate airflow. At the same time, a vent hole 30 is provided on the side of the base 3, and a round hole 31 is provided on the top of the base 3, and the round hole 31 is connected to the inside of the cabinet 1. Based on this, the open base 3 is connected to the outside through the vent hole 30, and the round hole 31 is linked to the inside of the cabinet 1. Therefore, when the fan 40 is working, it can stably and reliably promote the flow of air inside the cabinet 1, and improve the cooling capacity of the heat dissipation component 4 on the cabinet 1. In addition, the open base 3 is convenient for storing filters, thereby making the airflow entering the cabinet 1 cleaner.

[0026] In order to optimize the external structure of the cabinet 1 and protect the fan 40 , a cabinet door 2 is further provided at the bottom of the cabinet 1 , and the heat dissipation assembly 4 is closed inside the cabinet 1 through the cabinet door 2 .

[0027] To summarize, closing the fan 40 inside the cabinet 1 through the cabinet door 2 can, on the one hand, protect the fan 40 while utilizing the fan 40 to promote airflow inside the cabinet 1 to facilitate the discharge of heat inside the cabinet 1; on the other hand, by opening the cabinet door 2, the fan 40 can be easily slid out, and the user can also inspect and repair the fan 40.

[0028] Based on this, the fan 40 can be easily inspected and repaired while the cabinet door 2 can be used to protect the fan 40. In particular, closing the cabinet door 2 can optimize the external structure of the cabinet 1 and improve the sealing performance of the cabinet 1.

[0029] On the basis of the above scheme, a positioning piece 45 is further provided between the guide rail 41 and the slide rail 42; wherein one end of the positioning piece 45 is rotatably connected to the guide rail 41, and the other end of the positioning piece 45 is movably mounted on the slide rail 42. Therefore, the positioning piece 45 is connected to the guide rail 41 and the slide rail 42 to fix the two; conversely, loosening the positioning piece 45 does not affect the normal sliding of the two, so that the fan 40 can be ensured to work reliably inside the cabinet 1 while facilitating maintenance.

[0030] Specifically, an axial pin rod 44 is provided on both sides of the guide rail 41, and one end of the positioning piece 45 is axially connected to the axial pin rod 44; a connecting hole 43 is also provided on the slide rail 42, which is connected to the connecting hole 43 through a connecting piece 46 to fix the slide rail 42 on the guide rail 41. Based on this, the connecting piece 46 is loosened and the positioning piece 45 is rotated to contact the positioning of the slide rail 42.

[0031] In addition, the slide rail 42 is slidably matched with the slide groove 48 on the guide rail 41 through the inverted T-shaped sliding portion 47. Therefore, when the fan 40 completely slides out of the cabinet 1, the guide rail 41 and the slide rail 42 matched with the above structure will not peel off, so it can be ensured that during the sliding process of the fan 40, one end of the slide rail 42 will not be lifted up on the guide rail 41.

[0032] Furthermore, since a connecting column 49 is provided on the upper surface of the slide rail 42, when the bolt passes through the fixing ear of the fan 40 and is connected to the connecting column 49, the fan 40 can be reliably fixed. At the same time, before the bolt is installed, the connecting column 49 is inserted into the hole on the fixing ear to complete the positioning of the fan 40 before assembly.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
