[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. When the utility model is subjected to external vibration or impact, the box will push the shock-absorbing plate to move downward along the inside of the shock-absorbing seat.

When the sliding sleeve moves along the left and right ends of the cross bar, it will squeeze the first spring. Since the first spring can absorb vibration energy, it can effectively reduce the impact of vibration on the electrical components inside the box, play a good shock-absorbing and buffering role, and improve the overall stability and reliability of the distribution box.

[0015] 2.

The second spring can provide additional elastic buffering when impacted, thereby adding a layer of mechanical buffering outside the hydraulic system, which not only makes up for the lag of the hydraulic reaction time, but also ensures that a good shock-absorbing effect is maintained under extreme conditions. The second push rod, the second piston plate and the third spring together constitute another shock-absorbing link combining hydraulic and mechanical, which forms a linkage with the first push rod and the first piston plate to collaboratively complete the task of efficient shock absorption.

DETAILED DESCRIPTION

[0023] See also Figure 1-Figure 6 A distribution box with a distribution box protection structure includes a distribution box body 1, the distribution box body 1 includes a box body 101, a mounting plate 3 is provided at the bottom of the box body 101, and a shock absorbing mechanism 2 is fixedly connected between the box body 101 and the mounting plate 3:

[0024] Furthermore, the shock absorbing mechanism 2 includes a shock absorbing seat 201, a shock absorbing plate 203 is arranged inside the shock absorbing seat 201, clamping plates 208 are connected to the left and right sides of the top of the shock absorbing plate 203, the opposite side of the clamping plate 208 is in contact with the left and right sides of the box body 101, connecting rods 209 are rotatably connected to the left and right sides of the bottom left side of the shock absorbing plate 203, one end of the connecting rod 209 is rotatably connected to the sliding sleeve 210, the inner wall of the sliding sleeve 210 is slidably connected to a cross bar 211, the left and right ends of the cross bar 211 are fixedly connected to the left and right sides of the inner wall of the shock absorbing seat 201, and the sliding sleeves on the left and right sides of the surface of the cross bar 211 are provided with a first spring 212 fixedly connected between the shock absorbing seat 201 and the sliding sleeve 210.

[0025] The core component of the shock absorbing mechanism 2 is the shock absorbing seat 201, which is located between the box body 101 and the mounting plate 3, and is provided with a shock absorbing plate 203 inside. The left and right sides of the top of the shock absorbing plate 203 are tightly fitted with the box body 101 through the clamping plates 208, so that the box body 101 and the shock absorbing mechanism 2 form a stable connection relationship with a certain degree of mobility. When subjected to external vibration or impact, the box body 101 will push the shock absorbing plate 203 to move downward along the inside of the shock absorbing seat 201. When the shock absorbing plate 203 moves downward along the shock absorbing seat 201, the connection of the connecting rod 209 can drive the sliding sleeve 210 to move to the left and right sides of the cross bar 211. When the sliding sleeve 210 moves along the left and right ends of the cross bar 211, it will squeeze the first spring 212. Due to the existence of the first spring 212, it can absorb vibration energy, which can effectively reduce the impact of vibration on the electrical components inside the box body 101, play a good shock absorbing and buffering role, and improve the overall stability and reliability of the distribution box. It can effectively extend the performance and service life of the distribution box, and can effectively avoid the problem that vibration may cause reduced accuracy or failure.

[0026] Furthermore, a plurality of installation grooves 102 are equidistantly provided on one side of the box body 101 , a filter screen 103 is fixedly connected to the inner wall of the installation groove 102 , and a box door 104 is rotatably connected to the front side of the box body 101 .

[0027] The filter 103 is mainly provided to prevent dust, debris and other foreign particles from entering the interior of the distribution box, thereby protecting the cleanliness of the electrical equipment in the box and avoiding electrical failures and potential safety hazards caused by dust accumulation. The box door 104 can be opened quickly to inspect the internal components of the box body 101. At the same time, when closed, it can ensure the sealing and protective performance of the distribution box, prevent unauthorized personnel from contacting the internal electrical equipment, and ensure safe operation.

[0028] Furthermore, a plurality of heat dissipation holes 105 are equidistantly provided at the bottom of the front side of the cabinet door 104 , and a control key 106 and a handle 107 are fixedly connected to the front side of the cabinet door 104 .

[0029] The heat dissipation holes 105 are provided to ensure that the heat generated by the electrical components inside the distribution box during operation can be dissipated in time to avoid equipment damage and performance degradation due to excessive heating. At the same time, it can also maintain a constant operating temperature inside the distribution box to improve the stability and service life of electrical equipment. The control key 106 is usually used to perform some basic electrical operations, such as switching circuits, adjusting parameters and other functions; and the handle 107 is an operating component that facilitates the user to open and close the box door 104, so that the distribution box can be opened quickly and conveniently for corresponding operations or repairs in daily maintenance, inspection and emergency situations.

[0030] Furthermore, sliding grooves 202 are correspondingly opened on the left and right sides of the inner wall of the shock-absorbing seat 201, and the sliding grooves 202 are slidingly connected to the shock-absorbing plate 203. A dual-axis motor 205 is fixedly connected to the center of the top of the shock-absorbing plate 203, and threaded rods 206 are fixedly connected to the output ends of the left and right sides of the dual-axis motor 205. The opposite end of the threaded rod 206 is rotatably connected to the top of the shock-absorbing plate 203, and a threaded sleeve 207 is threadedly connected to the surface of the threaded rod 206.

[0031] When the dual-axis motor 205 is running, the rotation of the threaded rod 206 will drive the threaded sleeve 207 to move along the thread direction, and then the position of the shock-absorbing plate 203 relative to the shock-absorbing seat 201 can be adjusted through the threaded transmission system. This dynamic adjustment function is convenient for actively adjusting the shock-absorbing effect according to the actual vibration frequency and intensity, so as to more accurately match different working environments, thereby improving the seismic resistance and operating stability of the entire distribution box system.

[0032] Furthermore, a limiting groove 204 is provided at the center of the top of the damping plate 203 , the limiting groove 204 is slidably connected to the bottom of the threaded sleeve 207 , and the top of the threaded sleeve 207 is fixedly connected to the bottom of the clamping plate 208 .

[0033] When the threaded sleeve 207 rotates on the threaded rod 206, it can only move linearly along the trajectory of the limit groove 204. The top of the threaded sleeve 207 is fixedly connected to the bottom of the clamping plate 208, which means that when the threaded sleeve 207 moves on the threaded rod 206, it will drive the clamping plate 208 to move synchronously, further affecting the position of the box 101 on the shock absorbing seat 201 for precise regulation.

[0034] Furthermore, a plurality of buffer members 213 are fixedly connected between the bottom of the inner wall of the shock absorbing seat 201 and the bottom of the shock absorbing plate 203, and the buffer member 213 includes a first push rod 214 slidably connected to the bottom of the shock absorbing plate 203, a first fixed sleeve 216 is slidably connected to the surface of the first push rod 214, a connecting pipe 217 is fixedly connected to one side of the first fixed sleeve 216, a second fixed sleeve 218 is fixedly connected to one end of the connecting pipe 217, a second push rod 220 is slidably connected to the top of the second fixed sleeve 218, the bottoms of the first fixed sleeve 216 and the second fixed sleeve 218 are fixedly connected to the bottom of the inner wall of the shock absorbing seat 201, and the first fixed sleeve 216 and the second fixed sleeve 218 are filled with hydraulic oil.

[0035] When the shock absorbing plate 203 is forced to move up and down, the first push rod 214 will slide in the first fixed sleeve 216 under the push of the shock absorbing plate 203. When the first push rod 214 is forced to move downward, the second push rod 220 will slide upward through the transmission of hydraulic oil, and vice versa. In this way, energy absorption and dispersion are achieved, reducing the impact of vibration on the distribution box.

[0036] Furthermore, a rubber suction cup is fixedly connected to the top of the first push rod 214 and the second push rod 220, the bottom of the first push rod 214 extends to the inside of the first fixed sleeve 216 and is fixedly connected to the first piston plate 215, a second spring 221 is fixedly connected between the first piston plate 215 and the first fixed sleeve 216, the bottom of the second push rod 220 extends to the inside of the second fixed sleeve 218 and is fixedly connected to the second piston plate 219, and a third spring 222 is fixedly connected between the second piston plate 219 and the second fixed sleeve 218.

[0037] The introduction of the rubber suction cup increases the softness and elasticity of the contact surface, which can better absorb and alleviate the impact force caused by vibration, while reducing noise. When the first push rod 214 moves up and down under the action of the shock absorbing plate 203, the first piston plate 215 will produce reciprocating motion in the hydraulic oil in the first fixed sleeve 216. The hydraulic oil is compressed and released in the gap between the first piston plate 215 and the first fixed sleeve 216, forming a hydraulic resistance, which helps to consume and disperse the vibration energy. The second spring 221 can provide additional elastic buffering when it is impacted, so that it adds a layer of mechanical buffering outside the hydraulic system, which not only makes up for the lag of the hydraulic reaction time, but also ensures that a good shock absorbing effect is still maintained under extreme conditions. The second push rod 220, the second piston plate 219 and the third spring 222 together constitute another shock absorbing link combining hydraulic and mechanical, which forms a linkage with the first push rod 214 and the first piston plate 215 to jointly complete the task of efficient shock absorption.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
