[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] A shock-absorbing and silent wheel mounting structure for an incubator comprises a mounting frame 1, a shaft 2 and a roller 3, wherein the shaft 2 and the roller 3 are fixedly connected, a support seat 4 is arranged outside the mounting frame 1, an inner surface wall of the support seat 4 is rotatably connected to the shaft 2 through a bearing, a fixing plate 5 is fixedly mounted on the outer surface wall of the mounting frame 1, a spring 9 is fixedly mounted between the bottom of the fixing plate 5 and the top of the support seat 4, a shock absorber 6 is arranged between the fixing plate 5 and the support seat 4, and the shock absorber 6 is penetrated inside the spring 9;

[0025] The mounting frame 1 is fixedly connected to the box body. During the transfer of the box body through the roller 3, the roller 3 is always in contact with the working ground. The kinetic energy of the box body will cause the box body to compress the spring 9 through the fixing plate 5. The spring 9 realizes the energy absorption of the box body and cooperates with the shock absorber 6 to greatly reduce the bouncing of the box body, thereby realizing the shock absorption of the box body. In this way, while the convenient movement of the box body is realized through the roller 3 and the shaft 2, the vibration of the box body can be effectively reduced by the spring 9 in combination with the shock absorber 6. At the same time, the spring 9 provides an active characteristic between the box body and the roller 3, and cooperates with the sound-absorbing cotton installed on the inner wall of the top cover 8, so as to reduce the noise generated by the collision and friction between the roller 3 and the ground.

[0026] Specifically, Figure 2 and Figure 4 As shown, the cross-section of the mounting frame 1 is a U-shaped structure, and a strap is integrally formed at the horizontal end of the mounting frame 1. The inner wall of the strap is screwed and connected with a locking rod 7, so as to meet the installation requirements of the box and the roller 3, ensuring the stability of the position of the roller 3 while facilitating the subsequent separation of the roller 3 from the box. The fixing plate 5 is integrally formed with the mounting frame 1 to ensure the structural strength of the fixing plate 5, and the outer wall of the shock absorber 6 is in contact with the inner wall of the spring 9, so that the shock absorber 6 can reduce the vibration of the box while limiting the horizontal displacement of the spring 9.

[0027] Specifically, Figure 2 and Figure 3 As shown, a connecting seat 10 is fixedly installed on the outer wall of the mounting frame 1. The connecting seat 10 is mounted on the outer side of the shaft rod 2, and the inner wall of the connecting seat 10 is slidably connected to the shaft rod 2 through a vertically arranged slide groove 11. The connecting seat 10 is fixed to the mounting frame 1 through a protrusion 13, and the connecting seat 10 is slidably matched with the shaft rod 2 through the vertically arranged slide groove 11, so as to limit the vertical offset amplitude of the shaft rod 2 and the roller 3, and at the same time provide horizontal prestress for the shaft rod 2, thereby ensuring the stability of the rotation of the shaft rod 2 and preventing it from swinging horizontally.

[0028] Specifically, Figure 1 and Figure 2 As shown, a convex piece 13 is fixedly installed on the outer wall of the connecting seat 10, and the convex piece 13 is fixedly connected to the mounting frame 1 by screws, thereby ensuring the stable position of the connecting seat 10. The screws can be separated later to achieve the separation of the connecting seat 10. A top cover 8 is fixedly installed on the top of the connecting seat 10 through a top plate 12. Sound-absorbing cotton is fixedly installed on the side of the top plate 12 close to the roller 3 and the inner wall of the top cover 8. The roller 3 contacts the ground for displacement, and most of the noise generated by friction and collision will be absorbed by the sound-absorbing cotton inside the top plate 12 and the top cover 8. The spring 9 provides a movable characteristic between the box body and the roller 3, thereby achieving effective noise reduction of the roller 3.

[0029] Working principle: The mounting frame 1 is fixedly connected to the box body. During the transfer of the box body through the roller 3, the roller 3 always contacts the working ground. The kinetic energy of the box body will cause the box body to compress the spring 9 through the fixing plate 5. The spring 9 realizes the energy absorption of the box body and cooperates with the shock absorber 6, which can greatly reduce the jumping of the box body, thereby realizing the shock absorption of the box body. In this way, while realizing the convenient movement of the box body through the roller 3 and the shaft rod 2, the spring 9 cooperates with the shock absorber 6 to effectively reduce the vibration of the box body. At the same time, the spring 9 provides the movable characteristics between the box body and the roller 3, and cooperates with the sound-absorbing cotton installed on the inner surface wall of the top cover 8, so as to reduce the noise generated by the collision and friction between the roller 3 and the ground. The connecting seat 10 is fixed to the mounting frame 1 through the convex piece 13, and the connecting seat 10 is slidably cooperated with the shaft rod 2 through the vertically arranged slide groove 11, so as to limit the vertical offset amplitude of the shaft rod 2 and the roller 3, and at the same time, it can provide the shaft rod 2 with horizontal prestress, thereby ensuring the stability of the rotation of the shaft rod 2 and avoiding its horizontal swing.
