[0021] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0022] Embodiment: A pull-out switchboard device, such as Figure 1-5As shown, it includes an outer shell 1, an inner shell 2, a placement rack 3, a connecting plate 4, a contact rod 5 and an elastic member 6. Two ventilation grilles 8 are provided on the top and bottom of the outer shell 1. The ventilation grilles 8 create good ventilation and heat dissipation conditions for the inside of the outer shell 1 and provide certain protection while maintaining ventilation. The inner shell 2 is slidably connected to the outer shell 1. Screw holes 7 are provided on the front of the outer shell 1 and the front of the inner shell 2. Three placement racks 3 are provided in the inner shell 2. There are two connecting plates 4. The left and right sides of all the placement racks 3 are respectively fixed by a connecting plate 4. A contact rod 5 is fixed on the top of the connecting plate 4. The rear end of the contact rod 5 is an inclined surface with a high front and a low back. The left and right sides of the inner shell 2 are respectively provided with sliding grooves 201 with the same number and corresponding positions as the placement racks 3. The lower parts of the two connecting plates 4 are slidably connected to all adjacent sliding grooves 201, and an elastic member 6 is connected between the inner top of each adjacent sliding groove 201.

[0023] like Figure 2 As shown, an L-shaped mounting block 101 is also included. At least one L-shaped mounting block 101 is fixedly connected to the top and bottom of the outer shell 1. When multiple switchboard devices need to be installed side by side, they are installed and fixed through the L-shaped mounting blocks 101 of the upper and lower adjacent outer shells 1. The L-shaped mounting block 101 allows the upper and lower adjacent outer shells 1 to maintain a larger gap after installation, thereby ensuring the heat dissipation effect of the ventilation grille 8.

[0024] like Figure 1 As shown, a baffle 9 is also included. The top and bottom of the outer shell 1 are slidably connected with baffles 9 of the same number as the ventilation grilles 8 and corresponding in position. When dust or water prevention is required, the baffles 9 can be slid to cover the ventilation grilles 8 to prevent dust or water from entering the outer shell 1 through the ventilation grilles 8 and causing damage to the electrical components.

[0025] like Figure 3 As shown, a pull rod 202 is also included. The pull rod 202 is fixedly connected to the front side of the inner shell 2, and the pull rod can facilitate the push and pull operations on the inner shell 2.

[0026] Working principle: When it is necessary to install electrical components, install the electrical components on the placement rack 3, and then push the inner shell 2 inward through the pull rod 202 to make it slide into the outer shell 1. During this process, the outer shell 1 will first contact the inclined surface of the contact rod 5, and exert downward pressure on the contact rod 5 through the inclined surface, so that the contact rod 5 drives the connecting plate 4 and the placement rack 3 to move downward, and the distance between the lower part of the connecting plate 4 and the top of the corresponding slide groove 201 increases, so that the elastic member 6 will be stretched. Under the elastic force of the elastic member 6, the movement of the connecting plate 4 in the slide groove 201 becomes smooth and controlled, ensuring that the placement rack 3 can be stably received in the inner shell 2. When the inner shell 2 completely slides into the outer shell 1, the screw holes 7 at the front of the outer shell 1 and the front of the inner shell 2 will be aligned. At this time, the two are fixed by bolts to ensure the structural stability between the inner shell 2 and the outer shell 1.

[0027] When it is necessary to maintain the electrical components, the inner shell 2 is pushed outward by the pull rod 202 to make it slide out of the outer shell 1. During this process, the contact rod 5 gradually moves outward with the inner shell 2, and when the inclined surface of the contact rod 5 contacts the outer shell 1, the contact rod 5, under the elastic force of the elastic member 6, will drive the connecting plate 4 and the placement rack 3 to move upward and reset, thereby exposing the electrical components on the placement rack 3 from the inner shell 2 to facilitate maintenance.

[0028] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
