[0026] The effect achieved by the whole embodiment 1 is that: in the application of support structure, first, two L-shaped corrugated protective covers 10 provide basic protection for rubber support 2, the two L-shaped corrugated protective covers 10 are tightly bonded together by adhesive, which builds an effective isolation barrier for rubber support 2, effectively preventing the intrusion of harmful substances such as external water vapor and dust, at the same time, the flexible deformation characteristics of L-shaped corrugated protective cover 10 enable the support structure to maintain good sealing and adaptability during sliding, ensuring that the protection effect is not affected by movement, in order to further enhance the stability of the protective cover assembly, a spring fixing assembly is used to firmly fix the two L-shaped corrugated protective covers 10, this elastic fixing method not only adapts to various vibration environments, but also avoids the screw shedding problem that may occur in traditional screw fixing due to long-term vibration or stress concentration, thereby ensuring the durability and reliability of the protective cover assembly, in addition, the four waterproof air permeable membranes 7 and four groups of vent holes 9 ensure that the gas pressure inside and outside the protective cover assembly is balanced, this way not only provides the necessary environmental conditions for the long-term stable operation of rubber support 2, but also realizes the free circulation of air, while allowing air to circulate, the four waterproof air permeable membranes 7 can effectively block the intrusion of moisture, thereby ensuring that rubber support 2 always remains dry, through multiple protection measures, the protection function of the support structure is effectively improved, which enables it to maintain good performance in various harsh environments, thereby ensuring the stability and durability of the support structure, prolonging its service life.

[0027] The working principle of the whole device is as follows: in use, first of all, two L-shaped corrugated protective covers 10 provide a basis and comprehensive protection for the rubber support 2, and the two L-shaped corrugated protective covers 10 build a solid physical barrier for the rubber support 2, effectively isolating the intrusion of harmful substances such as water vapor and dust, at the same time, eight groups of first springs 14 act on the top of the four pressing plates 13 by using their elastic force, so that the eight pressing plates 13 can tightly fit the top and bottom protruding parts of the two L-shaped corrugated protective covers 10, realizing stable fixation, this elastic fixation method not only enhances the stability of the structure, but also can effectively avoid loosening or displacement caused by vibration, in addition, through the synergistic effect of the four waterproof breathable membranes 7 and the four groups of ventilation holes 9, the pressure inside and outside the two L-shaped corrugated protective covers 10 can be balanced, the four waterproof breathable membranes 7 are made of special materials, and the working principle is to allow dry air to flow freely while effectively blocking the penetration of moisture, thereby providing good environmental conditions for the long-term safe operation of the rubber support 2, however, in the long-term use process of the support structure, dust will inevitably accumulate in the four dust screens 8, thereby reducing the efficiency of air circulation, when it is necessary to clean or replace the dust screen 8, the user only needs to easily pull the corresponding two sliders 19, so that the two limiting blocks 17 move outward and are separated from the inside of the limiting groove 16, thereby releasing the fixation of the dust screen 8, at this time, the dust screen 8 can be easily removed for necessary maintenance operation, and the movement of the two sliders 19 will also extrude the corresponding second springs 20, generating a certain reverse elastic force, when it is necessary to reinstall the dust screen 8, only need to place the dust screen 8 in place, use the elastic recovery force of the two second springs 20, can quickly realize the fixation of the dust screen.
