Referring to fig. 2 and 3, the bottom plate 12 is fixed to the ground of the side plate 11. A damping plate 3 positioned in the cabinet body 1 is vertically and slidably connected above the bottom plate 12. The bottom plate 12 is provided with a buffer groove 121, and a buffer cylinder 7 is installed in the buffer groove 121. A plurality of horizontal springs 8 which are horizontally arranged are circumferentially arranged between the outer wall of the buffer cylinder 7 and the buffer groove 121.
Referring to fig. 2 and 3, the buffer tube 7 has a communication groove 13 formed therein, and the communication groove 13 has a U-shaped longitudinal section. The communication groove 13 includes a vertical sliding groove 131 and a support groove 132, and the bottoms of the support groove 132 and the sliding groove 131 are communicated through a transition groove 133. The transition groove 133 is filled with damping fluid.

When the damping rod 32 is abutted against the limit block 134, the damping rod 32 is lowered to the lowest position, and at this time, the lower end of the damping rod 32 is still higher than the transition groove 133, so that the lower end of the sliding groove 131 can be always communicated with the supporting groove 132, and the damping fluid can flow back conveniently.
Referring to fig. 2, during the downward movement of the shock-absorbing rod 32, the damping fluid is pressed into the supporting groove 132, and the level of the damping fluid in the supporting groove 132 rises, thereby lifting up the supporting rod 4. The length of the support rod 4 is smaller than that of the shock-absorbing rod 32. When the shaking force is great, shock-absorbing rod 32 moves down the volume when more, bracing piece 4 is contradicted until bracing piece 4 and shock attenuation board 3's lower surface by jack-up gradually, and bracing piece 4 supports shock attenuation board 3, prevents that shock attenuation board 3 vibration amplitude is great, influences the holistic stability of equipment.

When the push rod 24 slides up and down, the rotating shaft 231 rotates, thereby driving the fan blades 232 to rotate to form wind power. When the cabinet door 2 is closed, the lower end of the push rod 24 is abutted against the damping plate 3. After the cabinet door 2 is closed, when the damping plate 3 is vibrated up and down by the vibration force, the pushing rod 24 is driven to slide up and down, and the pushing rod 24 drives the rotating shaft 231 and the fan blades 232 to rotate. On one hand, the heat dissipation fan 23 rotates to form wind power to cool the equipment, and on the other hand, the heat dissipation fan 23 rotates to absorb and consume the vibration force of the damping plate 3, so that the damping performance is improved. And because the diameter of the transition gear 25 becomes smaller gradually, even if the displacement of the push rod 24 is smaller, the number of turns of rotation finally transmitted to the rotating shaft 231 is larger, thereby ensuring the heat dissipation effect.

Referring to fig. 5 and 6, when the lever 6 is in the locking state, the control spring 63 is compressed, the locking piece 62 is inserted into the locking groove 14, and the connecting block 61 is disengaged from the connecting groove 51.
Referring to fig. 5 and 6, when the lever 6 is in the open state, the control spring 63 is in a natural state, the locking piece 62 is disengaged from the locking groove 14, and the connecting block 61 is disengaged from the connecting groove 51.
Referring to fig. 5 and 6, when the control lever 6 is in the open state, the control spring 63 is in the fully compressed state, the locking piece 62 is located in the locking groove 14, and the connecting block 61 is embedded in the connecting groove 51.
Referring to fig. 5 and 6, when operating personnel opened cabinet door 2, operating personnel pressed control lever 6 earlier for stay 62 inlays in locking groove 14, and operating personnel rotated control lever 6, unscrewed stay 62 from locking groove 14, and at this moment, control lever 6 drove the ring gear 5 rotatory, and ring gear 5 drove catch bar 24 lifting, and catch bar 24 is extracted from accommodating the inslot, so that cabinet door 2 opened.
Referring to fig. 5 and 6, when the operator closes the cabinet door 2, the operator first presses the control lever 6 to insert the locking piece 62 into the locking groove 14, to close the cabinet door 2, and then rotates the control lever 6 to screw the locking piece 62 into the locking groove 14, at which time the pushing rod 24 (see fig. 4) is also brought into the receiving hole 33 (see fig. 4).
The implementation principle of the cabinet type cable fireproof device in the embodiment of the application is as follows: an operator can open or close the cabinet door 2 by operating the control rod 6, and the operation is convenient. When the cabinet body 1 is vibrated, the horizontal spring 8 can absorb and damp the vibration force in the horizontal direction, the damping plate 3 vibrates up and down, and the damping rod 32 and the heat radiation fan 23 absorb and consume the vibration force, so that the stability of the equipment is ensured, and the overall vibration resistance of the device is improved.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
