[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.
[0019] It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention 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 cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a low-voltage withdrawable switch cabinet of this embodiment includes a cabinet body and a drawer unit 2, wherein the drawer unit 2 is slidably connected to the cabinet body 1 through a slide rail 3, and each drawer unit 2 is provided with a support unit 4, wherein the support unit 4 includes an upper pull rod 41 and a lower pull rod 42, wherein the upper pull rod 41 and the lower pull rod 42 are detachably connected, the upper pull rod 41 is hinged to the cabinet body 1, and the lower pull rod 42 is connected to the drawer unit 2, and the lower pull rod 42 is hinged to the outer end of the side wall of the drawer unit 2, and the hinge point is located above the slide rail 3, so that the support unit 4 does not affect the sliding of the drawer unit 2, and the hinge point of the upper pull rod 41 and the cabinet body 1 is higher than the hinge point of the lower pull rod 42, so that when the upper pull rod 41 and the lower pull rod 42 are connected to provide support, the support unit 4 is inclined and can form a stable triangular structure with the cabinet body 1 and the drawer unit 2. When maintenance is required, the operator pulls out the drawer unit 2 and connects the ends of the upper pull rod 41 and the lower pull rod 42, so that after the drawer unit 2 is completely pulled out, the support unit 4 can form a stable triangular structure with the cabinet 1 and the drawer unit 2, and provide a pulling force to the outer end of the drawer unit 2, so as to avoid the drawer unit 2 being separated from the cabinet 1 during the maintenance process, or the drawer unit 2 being not closed tightly after the maintenance. After the maintenance is completed, the upper pull rod 41 and the lower pull rod 42 are disassembled from the connection, and the lower pull rod 42 is retracted to the side of the drawer unit 2 to facilitate the closing of the drawer unit 2.
[0022] The connecting end of the upper pull rod 41 and the lower pull rod 42 is provided with a locking unit 43 for connecting the upper pull rod 41 with the lower pull rod 42. Preferably, the upper pull rod 41 and the lower pull rod 42 are connected by threads, that is, the locking unit 43 includes a threaded hole located at the upper pull rod 41 or the lower pull rod 42 and a screw portion located at the lower pull rod 42 or the upper pull rod 41; or the locking unit 43 is a screw, and the upper pull rod 41 or the lower pull rod 42 is provided with a through hole matching the screw, and the screw passes through the through hole of the upper pull rod 41 or the lower pull rod 42 to achieve the connection between the upper pull rod 41 and the lower pull rod 42, or the ends of the upper pull rod 41 or the lower pull rod 42 are respectively provided with clamps with notches, and the ends of the upper pull rod 41 or the lower pull rod 42 are clamped by the clamps to achieve the connection between the upper pull rod 41 and the lower pull rod 42.
[0023] The length of the upper pull rod 41 is smaller than the height of the drawer unit 2, that is, after the upper pull rod 41 and the lower pull rod 42 are disassembled, the upper pull rod 41 does not contact the outer side wall component of the drawer unit 2, thereby preventing the upper pull rod 41 from being too long and affecting the withdrawal and sliding of the drawer unit 2. At the same time, it is beneficial for the upper pull rod 41 to be hidden between the drawer unit 2 and the cabinet body 1 after the drawer unit 2 is closed.
[0024] The lower pull rod 42 is a retractable pull rod. After the lower pull rod 42 is connected to the upper pull rod 41, it is convenient to lift and support the outer end of the drawn drawer unit 2. At the same time, after the lower pull rod 42 is retracted, it is convenient to hide in the side wall of the drawer unit 2 to avoid affecting the pulling and sliding of the drawer unit 2.
[0025] The support unit 4 is located on both sides of the drawer unit 2. The support unit 4 is located at the side of the drawer unit 2 to avoid affecting the maintenance of the electrical components in the drawer.
[0026] The side wall of the drawer unit 2 is provided with a clip for fixing the lower pull rod 42. After the lower pull rod 42 is retracted, the lower pull rod 42 can be fixed to the outer side wall of the drawer unit 2 by the clip to avoid affecting the pulling and sliding of the drawer unit 2.
