DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-Figure 6 , the utility model provides the following technical solutions: a central cabinet switch device:

[0033] Embodiment 1: By providing a long pin 6 and a slot 7, the left door panel 2 and the right door panel 4 are quickly engaged, as shown in FIG. Figure 1-Figure 4 As shown:

[0034] The cabinet comprises a cabinet body 1, a left door panel 2 is hingedly connected to the left end surface of the front side of the cabinet body 1, a right door panel 4 is hingedly connected to the right end surface of the front side of the cabinet body 1, and a fixing block 3 is fixedly connected to the surface of the left door panel 2;

[0035] A central cabinet switchgear further comprises:

[0036] Auxiliary block 5, the auxiliary block 5 is fixedly connected to the surface of the right door panel 4, and a card slot 7 is opened on the surface of the auxiliary block 5, an upper connecting plate 13, the upper connecting plate 13 is fixedly connected to the upper surface of the cabinet 1, and a push rod 14 is slidably arranged inside the upper connecting plate 13.

[0037] A long pin 6 corresponding to the card slot 7 is slidably provided inside the fixed block 3, and the end of the long pin 6 is inclined, and the surface of the long pin 6 is fixedly connected to a limit block 8, the limit blocks 8 are symmetrically distributed about the center of the long pin 6, and the end of the long pin 6 is fixedly connected to a handle 11, and a limit groove 10 corresponding to the limit block 8 is opened inside the fixed block 3.

[0038] A first spring 9 having an elastic reset function is fixedly connected to the surface of the limiting block 8 , and the other side of the first spring 9 is fixedly connected to the inner wall of the fixing block 3 .

[0039] During operation, when it is necessary to close the left door panel 2 and the right door panel 4, close the left door panel 2 first, and then close the right door panel 4. At this time, the auxiliary block 5 will push the long pin 6 through the inclined surface of the long pin 6. At this time, the long pin 6 will slide inside the fixed block 3, and then the long pin 6 will drive the limit block 8 to slide inside the limit groove 10. At the same time, the limit block 8 squeezes the first spring 9. When the left door panel 2 and the right door panel 4 rotate to fit with the cabinet body 1, the long pin 6 enters the slot 7 under the action of the limit block 8 and the first spring 9, that is, the left door panel 2 and the right door panel 4 have been closed, and the limit block 8 and the limit groove 10 limit the moving distance of the long pin 6 to ensure stability.

[0040] Embodiment 2: By setting the push rod 14, the staff can be assisted to open the right door panel 4, such as Figure 1 , Figure 5 and Figure 6 As shown:

[0042] During the installation of the left door panel 2 and the right door panel 4, the right door panel 4 will push the push rod 14 through the upper connecting block 12, so that the push rod 14 slides inside the upper connecting plate 13, and at the same time, the push rod 14 squeezes the second spring 15 through the force plate 16, so that the second spring 15 is always in a state of storing force. When it is necessary to open the left door panel 2 and the right door panel 4, the handle 11 is directly pulled so that the handle 11 drives the end of the long pin 6 to move out of the slot 7. At this time, the left door panel 2 and the right door panel 4 are not in a locked state, and then the push rod 14, under the action of the second spring 15, pushes the upper connecting block 12, so that the right door panel 4 is opened, which plays a role in assisting the cabinet opening.

[0043] Embodiment 3: Different from Embodiment 2, the limit plate 17 is provided to limit the moving distance of the push rod 14, thereby ensuring stability. Figure 6 As shown:

[0044] The push rod 14 passes through the interior of the upper connecting plate 13 , and the end of the push rod 14 is fixedly connected to the limiting plate 17 .

[0045] During the movement of the push rod 14 , the force plate 16 and the limit plate 17 limit the moving distance of the push rod 14 , thereby ensuring stability.

[0046] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
