[0025] Example: Reference Figure 1-5 A protective mechanism for an elevator car shown in the figure comprises a car body 1, a protective plate 2 is arranged on the rear side of the car body 1, a slide groove 3 is opened at the inner bottom of the car body 1, a plurality of sliding balls 4 are filled at the bottom of the slide groove 3, a plurality of sliding blocks 5 are slidably arranged between the sliding balls 4 and the slide groove 3, a mounting plate 6 is fixedly connected to the top of the sliding block 5, a same bottom plate 7 is installed on the top of the plurality of mounting plates 6, a tail plate 8 is fixedly connected to the end of the car body 1 near the slide groove 3, a plurality of fixing bolts 9 are penetrated and connected to the top of the bottom plate 7, and the bottom of the fixing bolts 9 penetrates the car body 1. The car body 1 and protective plate 2 in this embodiment are the main body of the elevator car and the protective mechanism components, the protective plate 2 is used for the protection of the car and the loading truck, and the bottom plate 7 is used to increase the protection of the bottom of the car body 1, which can improve the wear resistance and replacement convenience of the bottom of the car, and facilitate the cleaning of the bottom of the car body 1.
[0026] There are two groups of slide grooves 3, and the two groups of slide grooves 3 are arranged in parallel on the car body 1. The slide grooves 3 are arranged to penetrate the ends of the car body 1. The slide grooves 3 are convenient for adding sliding guide rails on the inner side of the car body 1, so that by filling multiple sliding balls 4 in the slide grooves 3, the sliding balls 4 can rotate in the slide grooves 3, thereby facilitating the movement of the position of the sliding balls 4 and improving the moving convenience of the fixing bolts 9.
[0027] A slide-out groove 14 is provided at the top of the tail plate 8, and the cross-sectional area of the slide-out groove 14 is smaller than the cross-sectional area of the slide groove 3. The slider 5 passes through the slide-out groove 14 and the tail plate 8. The through-arrangement of the slide groove 3 and the end of the car body 1, and the through-arrangement of the slide-out groove 14 and the slide groove 3, make it easy for the slider 5 to slide out of the slide groove 3, separate the bottom plate 7 from the car body 1, and then realize the replacement of the bottom plate 7, thereby increasing the convenience of cleaning the materials on the bottom plate 7.
[0028] A mounting groove 11 is provided on the mounting plate 6, and a mounting bolt 12 is connected through the mounting groove 11. The mounting bolt 12 and the bottom plate 7 are threadedly penetrated. The mounting groove 11 and the mounting bolt 12 facilitate the detachable structure of the mounting plate 6 and the bottom plate 7, facilitate the disassembly of the slider 5 and the bottom plate 7, and increase the convenience of replacing the bottom plate 7.
[0029] A rubber pad 13 is arranged between the slider 5 and the mounting plate 6. The bottom of the slider 5 is arranged as an arc structure. The slider 5 is located on the upper side of the sliding ball 4.

The plurality of rough strips 10 are symmetrically arranged on the top of the bottom plate 7, and a carbon steel sheet 17 is fixedly connected to the bottom of the bottom plate 7. The rough strips 10 are used to increase the roughness of the top of the bottom plate 7, increase the friction between the bottom plate 7 and the truck, avoid sliding of the truck, and increase the hardness of the bottom plate 7.
[0032] How this utility works:
[0033] Before use, first fix two rows of sliders 5 at the bottom of the bottom plate 7, penetrate the mounting bolts 12 and the mounting grooves 11 in the mounting plate 6 at the ends of the sliders 5, and the mounting bolts 12 can be screwed into the bottom plate 7 to limit the position of the slider 5, and then push the pull-out rod 16 to pass the slider 5 through the slide-out groove 14 and slide toward the protective plate 2. The slider 5 drives a plurality of sliding balls 4 to roll and slide on the upper side of a plurality of sliding balls 4 to move the position of the bottom plate 7 so that the pull-out rod 16 covers the inner wall of the compartment 1 evenly, and then use a screwdriver to screw the fixing bolts 9 through the bottom plate 7 into the fixing grooves 15 of the compartment 1 to limit the position of the bottom plate 7. Limiting care increases the stability of the bottom plate 7. During the use of the car body 1, a number of rough strips 10 are set on the top of the bottom plate 7 to increase the friction between the loaded truck and the car body 1 and improve the sliding of the truck. During use, the fixing bolt 9 is unscrewed from the car body 1, and the bottom plate 7 is pulled by the pull-out rod 16, so that the bottom plate 7 can be pulled out from the car body 1, and the debris on the top of the bottom plate 7 can be quickly cleaned, which increases the convenience of cleaning the car body 1, and the bottom plate 7 can be quickly replaced, and then the bottom of the car body 1 can be protected, thereby improving the protection effect of the car and improving the use effect of the car.
