[0025] In order to clearly and completely describe the purpose and technical solution of the present utility model, and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, and are not used to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0026] Embodiment 1, please refer to Figures 1 - 7 , the present utility model provides a technical solution: a car board strengthening structure for an elevator car. A connecting groove 16 is provided on the surface of the inner wall 1 of the elevator. A sliding block 6 is provided on the inner wall of the connecting groove 16. A second rotating shaft 13 is fixed inside the sliding block 6. A transmission plate 7 is sleeved on the outer surface of the second rotating shaft 13. The impact force received by the transmission plate 7 will act on the sliding block 6 to push the sliding block 6. When the sliding block 6 moves in the connecting groove 16, it will squeeze the spring 5. The squeezing of the spring 5 will resolve the impact force received by the sliding block 6 and strengthen the strength of the car board 3 for the second time.

[0027] One side surface of the reinforcing plate 2 is fixed with the car board 3. One side surface of the reinforcing plate 2 close to the inner wall 1 of the elevator is fixed with a connecting plate 8. One side surface of the connecting plate 8 close to the inner wall 1 of the elevator is fixed with a first rotating shaft 10. The impact force received by the reinforcing plate 2 will act on the transmission plate 7. When the transmission plate 7 is impacted, it will change the angle between the transmission plate 7 and the connecting plate 8. The changed angle of the transmission plate 7 will push the sliding block 6.

[0028] On the basis of the first embodiment, in order to strengthen the strength of the car board 3, a sliding groove 15 is provided on the inner side surface of the connection groove 16. A spring 5 is fixed to the inner wall of the connection groove 16. A slider 14 is fixed to the outer surface of the sliding block 6. A groove 12 is provided on the top surface of the sliding block 6. A second rotating shaft 13 is fixed to the inner side surface of the groove 12. Positioning holes 11 are provided on the two end side surfaces of the transmission plate 7.

[0029] There are two groups of positioning holes 11, and the two groups of positioning holes 11 are symmetrically distributed on the two end side surfaces of the transmission plate 7. One end of the positioning hole 11 corresponds to the second rotating shaft 13, and the positioning hole 11 is clamped on the outer surface of the second rotating shaft 13, and the two are movably connected; the other end of the positioning hole 11 corresponds to the first rotating shaft 10, and the positioning hole 11 is clamped on the outer surface of the first rotating shaft 10, and the two are movably connected. The impact force received by the reinforcing plate 2 will act on the transmission plate 7. When the transmission plate 7 is impacted, the angle between the transmission plate 7 and the connection plate 8 will change. When the angle changes, the transmission plate 7 will push the sliding block 6.

[0030] A rubber block 4 is fixed to the side surface of the reinforcing plate 2 away from the elevator inner wall 1. The car board 3 is fixed to the end of the rubber block 4. The car board 3 will act the received impact force on the rubber block 4. Since the rubber block 4 has a shock absorption effect, the rubber block 4 will buffer the impact force received by the car board 3 once and strengthen the strength of the car board 3 once. A fixing block 9 is fixed to the side surface of the connection plate 8 close to the elevator inner wall 1. A first rotating shaft 10 is fixed to the inner surface of the fixing block 9. There are multiple groups of the first rotating shafts 10, and the multiple groups of the first rotating shafts 10 are circumferentially distributed on the surface of the connection plate 8; there are multiple groups of the sliding blocks 6, and the multiple groups of the sliding blocks 6 are circumferentially distributed on the surface of the elevator inner wall 1.

[0031] There are multiple groups of connection grooves 16, and the multiple groups of connection grooves 16 are circumferentially distributed on one side surface of the elevator inner wall 1, and the sliding block 6 corresponds to the connection groove 16. The sliding block 6 is clamped in the connection groove 16, and the two are movably connected. When the impact force received by the car board 3 is large, the rubber block 4 cannot completely resolve the impact force of the car board 3, and the remaining impact force will act on the sliding block 6; one end of the spring 5 is fixed to the surface of the sliding block 6, and the other end of the spring 5 is fixed to the inner wall surface of the connection groove 16, and the spring 5 is located on the inner wall of the connection groove 16 away from the center of the elevator inner wall 1. When moving in the connection groove 16, the spring 5 will be compressed. The compression of the spring 5 will resolve the impact force received by the sliding block 6 and strengthen the strength of the car board 3 for the second time.

[0032] There are multiple sets of sliders 14, and the multiple sets of sliders 14 are symmetrically distributed on the outer surface of the sliding block 6. There are multiple sets of sliding grooves 15, and the multiple sets of sliding grooves 15 are symmetrically distributed on the inner wall side surface of the connecting groove 16. Moreover, the sliders 14 correspond to the sliding grooves 15, and the sliders 14 are clamped in the sliding grooves 15, and the two are movably connected, which plays a positioning role in the movement of the sliding block 6 in the connecting groove 16 and prevents the sliding block 6 from shifting during movement.

[0033] During actual use, when the elevator car board 3 is externally collided, the car board 3 will act the received impact force on the rubber block 4. Since the rubber block 4 has a shock absorption effect, the rubber block 4 will buffer the impact force received by the car board 3 once and strengthen the strength of the car board 3 once. And when the impact force received by the car board 3 is relatively large, the rubber block 4 cannot completely resolve the impact force of the car board 3. The remaining impact force will act on the reinforcing plate 2 through the rubber block 4. The impact force received by the reinforcing plate 2 will act on the transmission plate 7, and the impact force received by the transmission plate 7 will act on the sliding block 6 to push the sliding block 6. The movement of the sliding block 6 in the connecting groove 16 will squeeze the spring 5, and the squeezing of the spring 5 will resolve the impact force received by the sliding block 6 and strengthen the strength of the car board 3 a second time. This structure is simple and easy to operate, realizes the strengthening of the strength of the car board 3, and is beneficial to improving its use effect.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
