Description

Technical Field

[0002] The distribution box is a circuit distribution box for all users' electricity. Working Principle The distribution box is a low-voltage power distribution device that assembles switchgear, measuring instruments, protective devices and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements.

[0003] In some special operating environments, such as mining plants, construction sites, and road and bridge projects, seismic-resistant distribution boxes are required. These boxes operate in high-vibration environments and are often subjected to continuous vibration, which can easily damage electrical components or loosen wiring, leading to poor contact, heat generation, loose connections, burnout, and even fire. However, existing distribution boxes are often mounted directly on walls or brackets without seismic-resistant structures, resulting in poor seismic performance. Utility Model Content

[0013] 1. The utility model provides a front and rear shock-absorbing mechanism so that the distribution box body can obtain a front and rear shock-absorbing effect. When the distribution box body is under maintenance or vibration is transmitted to the distribution box body, causing the distribution box body to move forward and backward, the distribution box body will drive the second combination plate to move toward the position of the first combination plate.

DETAILED DESCRIPTION

[0023] See also Figure 1-Figure 7A high-strength earthquake-resistant distribution box includes a distribution box body 1, and a front and rear shock absorbing mechanism 2, a horizontal shock absorbing mechanism 3 and a mounting plate 4 are provided on one side of the distribution box body 1;

[0024] The front and rear shock absorbing mechanisms 2 enable the distribution box body 1 to obtain a shock absorbing effect in the front and rear directions, and the horizontal shock absorbing mechanism 3 enables the distribution box body 1 to obtain a shock absorbing effect in the horizontal direction.

[0025] The front and rear shock absorbing mechanism 2 includes two first combination plates 201, the first combination plate 201 is fixed to the surface of the mounting plate 4, the first damping spring 202 is fixed to the surface of the first combination plate 201, the first movable block 203 is fixed to the surface of the first damping spring 202, the first movable block 203 is slidably connected to the surface of the first combination plate 201, the first movable block 203 is hinged to the surface of the first connecting rod 204, the first connecting rod 204 is hinged to the surface of the second combination plate 205, the second combination plate 205 is hinged to the distribution box body 1 The surface is fixedly connected, a second connecting rod 206 is hinged on the surface of the second combination plate 205, and two second movable blocks 207 are hinged on the surface of the second connecting rod 206. The second movable blocks 207 are slidably connected to the surface of the first combination plate 201. A second damping spring 208 is fixed between the surfaces of the second movable blocks 207 on both sides. Four active racks 209 are fixed to the surface of the second combination plate 205, and an airbag 210 is fixed to one end of the active rack 209. One end of the airbag 210 is fixedly connected to the surface of the first combination plate 201;

[0026] When the distribution box body 1 is under maintenance, or vibration is transmitted to the distribution box body 1, causing the distribution box body 1 to move forward and backward, the distribution box body 1 will drive the second combination plate 205 to move toward the position of the first combination plate 201. At this time, the first connecting rods 204 on both sides can expand outward, causing the first movable blocks 203 on both sides to move in opposite directions, thereby compressing the first damping spring 202, so that the first damping spring 202 can absorb part of the vibration. At the same time, the second connecting rods 206 on both sides will also rotate toward each other, so that the second movable blocks 207 on both sides can move toward each other, and the second damping spring 208 can also be compressed synchronously, so that the vibration can be further buffered and dispersed, and the active rack 209 can squeeze the airbag 210, so that the airbag 210 can again buffer the vibration and impact, so that the distribution box body 1 can have a high-strength seismic effect.

[0027] Furthermore, third combination plates 211 are provided on both the upper and lower sides of the second combination plate 205. The third combination plate 211 is fixed to the surface of the mounting plate 4. The surface of the third combination plate 211 is rotatably connected to two rotating shafts 212. Two driving gears 213 and two driven gears 214 are fixed to the surface of the rotating shaft 212. The driving gear 213 is engaged with the driving rack 209. The surface of the driven gear 214 is engaged with a driven rack 215. A third damping spring 216 is fixed between the surfaces of the driven racks 215 on both sides. A support structure is installed on the surface of the driven rack 215.

[0028] When the second assembly plate 205 moves toward the first assembly plate 201, the active rack 209 drives the active gear 213 to rotate, so that the active gear 213 can drive the driven gear 214 to rotate synchronously through the rotating shaft 212, thereby making the left and right driven racks 215 mesh with the driven gear 214 and start to move toward each other, so that the third damping spring 216 can be compressed to absorb the transmitted kinetic energy, thereby further improving the shock absorption and buffering effect.

[0029] Furthermore, the surface support structure of the driven rack 215 includes a sleeve 219, which is fixed to the surface of the driven rack 215. Two L-shaped plates 217 are fixed on the upper and lower sides of the surface of the first assembly plate 201. A slide rod 218 is fixed between the surfaces of the two L-shaped plates 217. The sleeve 219 is slidably connected to the surface of the slide rod 218.

[0030] When the driven rack 215 moves, the sliding sleeve 219 slides on the surface of the sliding rod 218, thereby ensuring that the driven rack 215 can obtain a supporting effect.

[0031] Furthermore, the horizontal shock absorbing mechanism 3 includes a fixed plate 301, a plurality of fixing holes are opened on the surface of the fixed plate 301, two slide rails 302 are fixed to the surface of the fixed plate 301, two sliders 303 are slidably connected to the surface of the slide rails 302, the surface of the sliders 303 is fixedly connected to the surface of the mounting plate 4, a first mounting block 304 is fixed to the surface of the fixed plate 301, a fourth damping spring 305 is fixed to the surface of the first mounting block 304, a second mounting block 306 is fixed to the surface of the fourth damping spring 305, and the surface of the second mounting block 306 is fixedly connected to the surface of the mounting plate 4;

[0032] The fixing holes are used to install the fixing plate 301 and the wall. The distribution box body 1 can drive the slider 303 to move horizontally left and right on the surface of the slide rail 302 through the mounting plate 4. During this process, the mounting plate 4 will drive the second mounting block 306 to move, so that the fourth damping spring 305 can be compressed, thereby buffering the horizontal vibration of the distribution box body 1.

[0033] Furthermore, a plurality of rollers 5 are fixed to the bottom of the distribution box body 1, and the surface of the rollers 5 is slidably connected to the surface of the mounting plate 4;

[0034] The distribution box body 1 can obtain a supporting effect on the bottom of the distribution box body 1 through the contact between the roller 5 and the surface of the mounting plate 4, and the roller 5 can reduce the friction between the bottom of the distribution box body 1 and the mounting plate 4 when the distribution box body 1 moves, thereby ensuring that the distribution box body 1 can obtain a supporting effect while also being able to move back and forth normally.

[0035] Furthermore, the airbag 210 is made of rubber;

[0036] Rubber has good elasticity and can quickly return to its original shape after being compressed, which ensures that the airbag 210 can effectively absorb vibration and impact.
