Technical Field

[0001] The utility model relates to the technical field of shockproof equipment for power distribution cabinets, in particular to a shockproof structure for power distribution cabinets. Background Art

[0002] The distribution cabinet is often subject to bumps and vibrations during transportation and movement. If the shockproof structure is unreasonable, it may cause vibration damage to the internal components of the distribution cabinet.

It includes a cabinet body, a base is provided at the bottom of the cabinet body, and a shockproof cushion is connected to the top of the base where it contacts the cabinet, and the inside of the shockproof cushion is cavity-shaped; an installation space is provided at the bottom of the base, and a rolling element is connected to the installation space, and the top of the rolling element is connected to the internal cavity of the shockproof cushion; guide components are respectively connected at both ends of the base, and an inclination angle difference is provided between the guide pick and the base. The utility model installs a base with a shockproof cushion at the bottom of the distribution cabinet.

[0003] However, the above-mentioned shockproof structure of the power distribution cabinet still has certain disadvantages in certain usage situations: on the one hand, the above-mentioned shockproof structure of the power distribution cabinet uses shock-absorbing springs, buffer sleeves and shock-absorbing cushions to reduce the shock of the power distribution cabinet. A single shock-absorbing spring does not have a shock-absorbing effect, and the shock-absorbing effect of the buffer sleeve and the shock-absorbing cushion is limited. Moreover, the above-mentioned shockproof structure of the power distribution cabinet only has a shock-absorbing effect on vibrations in the vertical direction. If it is a deflection force, the shockproof effect is not obvious. Therefore, a shockproof structure of the power distribution cabinet is proposed to solve the above-mentioned defects in a targeted manner. Summary of the invention

DETAILED DESCRIPTION

[0023] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0024] like Figure 1 , Figure 2 and Figure 5 As shown, a shockproof structure of a power distribution cabinet comprises: a mounting plate 2 arranged on an assembly base 1, an assembly hole 16 is arranged on the top surface of the mounting plate 2, the assembly hole 16 is threadedly connected to the power distribution cabinet (not shown in the figure), a first shock-absorbing structure and a plurality of second shock-absorbing structures are arranged between the mounting plate 2 and the assembly base 1, the first shock-absorbing structure comprises: a first damping shaft 3 hingedly connected to the bottom of the mounting plate 2, the lower end of the first damping shaft 3 is hingedly connected to the assembly base 1; the second shock-absorbing structure comprises: a support column 4 hingedly connected to the top surface of the assembly base 1 and a guide rail groove 5 arranged on the bottom surface of the mounting plate 2, a sliding column 6 is slidably arranged in the guide rail groove 5, the support column 4 is hingedly connected to the sliding column 6, both ends of the sliding column 6 are respectively connected to the end of the guide rail groove 5 through a second damping shaft 7, a reset spring 14 is arranged on the outer peripheral side of the second damping shaft 7, and both ends of the reset spring 14 are respectively connected to the sliding column 6 and one end of the guide rail groove 5. When the distribution cabinet is subjected to vertical vibration force, the distribution cabinet acts on the first shock-absorbing structure and the second shock-absorbing structure through the mounting plate 2. The first damping shaft 3 will directly absorb a part of the vibration force exerted on the distribution cabinet. The multiple support columns 4 will swing a certain amplitude according to the magnitude of the vibration force, and transfer the vibration force to the sliding column 6. The second damping shafts 7 located at both ends of the sliding column 6 further absorb the vibration force exerted on the sliding column 6, thereby effectively improving the shockproof effect.

[0025] like Figure 3 and Figure 4 As shown, in a preferred embodiment of the utility model, a spherical groove (not shown in the figure) is provided on the top surface of the assembly base 1 and the bottom surface of the mounting plate 2, and a spherical protrusion 12 is provided at both ends of the first damping shaft 3, and the two spherical grooves are respectively connected to the spherical protrusion 12 in a ball hinge manner, and an anti-wear pad 13 is provided between the spherical groove and the spherical protrusion 12 to extend the service life of the first shock-absorbing structure. When the distribution cabinet is subjected to a vibration force in a non-vertical direction, the first damping shaft 3 will produce a certain angle of deflection while absorbing the vibration force. At this time, the support column 4 located on the outer peripheral side of the first damping shaft 3 will produce swings in different directions, and each second damping shaft 7 will further absorb the vibration force received by the sliding column 6. Compared with the traditional spring and shrapnel shockproof method, the overall structure is more stable and the shockproof effect is better. At the same time, a buffer strip 11 is provided on the inner peripheral side of the assembly base 1. The buffer strip 11 is made of rubber material. When the deflection angle of the mounting plate 2 is large, the buffer strip 11 will buffer the impact force between the mounting plate 2 and the assembly base 1, and play a protective role on the overall equipment.

[0026] like Figure 6 As shown, a fixing seat is arranged below the assembly base 1, and the fixing seat includes: a guide plate 9 detachably arranged on the rubber mounting block 8, a threaded rod 10 is arranged on the guide plate 9, and the threaded rod 10 is threadedly connected to the assembly base 1. When the power distribution cabinet generates a certain vibration, the rubber mounting block 8 will absorb the vibration within a certain frequency range, further enhancing the shockproof effect. At the same time, an assembly groove is arranged on each of the two adjacent sides of the assembly base 1, and a level 15 is embedded in the assembly groove. When installing the power distribution cabinet, the horizontality of the power distribution cabinet can be adjusted in time by adjusting the length of the threaded rod 10 extending above the rubber mounting block 8.

[0027] The working principle of the utility model is as follows: when the distribution cabinet is subjected to vibration force, the distribution cabinet acts on the first shock-absorbing structure and the second shock-absorbing structure through the mounting plate 2, and the first damping shaft 3 directly absorbs a part of the vibration force exerted on the distribution cabinet to achieve the shock-absorbing effect. Each support column 4 will swing a certain amplitude according to the magnitude of the vibration force, and transfer the vibration force to the sliding column 6. The second damping shafts 7 located at both ends of the sliding column 6 further absorb the vibration force exerted on the sliding column 6, and the shock-proof effect is better.

[0028] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
