One side of the anti-cracking plate is fixedly connected with an anti-corrosion plate, and one side of the anti-corrosion plate is fixedly connected with an anti-permeation plate. According to the utility model, the buffer plate can play a role in buffering the wall body, the anti-cracking plate is made of a material with excellent impact resistance, so that the anti-cracking effect can be achieved, and the steel plate is very hard, so that the pressure resistance and the impact resistance of the device can be greatly improved, and when the device is impacted by the outside, the anti-cracking effect can be achieved. The wall body is not prone to cracking, the anti-corrosion plate is made of materials with a very good anti-corrosion effect, and the very good anti-corrosion effect can be achieved in a humid environment.

The utility model belongs to the technical field of coaming boxes, and particularly discloses a coaming box capable of resisting stress deformation, which comprises a tray, a box body is arranged at the top of the tray, a box cover is detachably mounted at the top of the box body, a fixed table is fixedly connected to the outer surface of the tray, a first concave frame is fixedly connected to the top of the fixed table, and a second concave frame is fixedly connected to the bottom of the first concave frame. A first frame shaft is fixedly arranged on the inner side of the first concave frame in a penetrating mode, a swing plate is rotationally connected to the outer surface of the first frame shaft, and a pressure-resistant plate is fixedly connected to the top of the swing plate. According to the coaming box capable of resisting stress deformation, the sliding frames transversely move along the sliding rails, supporting points can be accurately adjusted according to the deformation position of the box body, the problem of local pressure concentration caused by distribution of different goods is solved, the two sets of concave pressure-resisting plates are matched to synchronously swing and draw close, wrapping type supporting on the box body is formed, the single-point pressure is dispersed, and the bearing capacity of the box body is improved. And the concave structure is matched with the outer wall of the box body, so that the overall torsional strength is enhanced, and the stress deformation resistance of the coaming box is remarkably improved.

The present application relates to the technical field of cable, in particular to an anti-deformation cable, which comprises a cable core layer wrapping a cable core part, a strip-shaped armor clamped on the cable core layer in the axial direction, and the number of strip-shaped armors is not less than four, the four strip-shaped armors are axially spaced, and a transition limiting belt is clamped between the axial position of the strip-shaped armors, the arc-shaped ends of the transition limiting belt are clamped between the adjacent two strip-shaped armors, there is a gap between the two transition limiting belts, and the number of the strip-shaped armors and the transition limiting belt is equal. Compared with the existing armored cable, the present application has a three-in-one protection mechanism, and has good performance and good reset mechanism in terms of anti-torsion, anti-pressure and anti-stretching. In addition, when connecting the cable, no accessories are needed, the intermediate transition limiting belt is directly clamped behind the strip-shaped armor to form an intermediate layer of armored effect, which is convenient to use, has lower weight, and is suitable for use in multiple scene construction.

A pressure-resistant and anti-aging cable is provided to address the technical problem mentioned in the background art: existing cables lack a pressure-resistant structure, making them susceptible to compression and bending during construction or use, leading to insulation cracking or even conductor breakage, causing short circuits or leakage faults. The cable core includes an insulation layer covering its outer wall, a first protective layer covering the outer wall of the insulation layer, a second protective layer on the outer wall of the first protective layer, and several ring-shaped, equidistantly distributed air pockets for buffering between the first and second protective layers. A pressure-resistant inner tube is located on the outer wall of the second protective layer, and a pressure-resistant outer tube is located on the outer wall of the pressure-resistant inner tube. Several ring-shaped, equidistantly distributed support rods are fixed between the pressure-resistant inner tube and the pressure-resistant outer tube, and a pressure-resistant component is provided between adjacent support rods to improve the pressure resistance of the pressure-resistant outer tube.
