AI Technical Summary
Existing food display refrigerators have sliding doors that are difficult to open after frost has formed, which is time-consuming, labor-intensive, and may damage the equipment.
A sliding door system was designed, including a sliding block, a pressing block, transmission teeth, a rotating block, a handle, a rotating shaft, and rotating teeth. By meshing the transmission teeth and rotating teeth, the sliding block is driven to slide, causing the pressing block to press against the inner wall of the freezer, providing a reaction force to push the sliding door open, combined with a rubber pad to buffer the impact force.

The rubber pad 21 can effectively absorb the impact force generated by the collision, prolonging the service life of the refrigerator.
[0037] The working principle of the utility model is as follows: when the sliding door 2 of the food sales display refrigerator is difficult to open due to frost condensation, first, hold the handle 31, the handle 31 is closely connected with the rotating block 3, when the hand applies force to rotate the handle 31, the rotating block 3 also starts to rotate, the rotating shaft 32 is driven to rotate by the rotating block 3, the rotating teeth 33 start to move under the driving of the rotating shaft 32, and the transmission teeth 24 are meshed with each other and start to mesh, which provides power for the subsequent action. Under the driving of the transmission teeth 24, the sliding block 22 starts to slide outward, and the extrusion block 23 installed at the end of the sliding block 22 synchronously follows the sliding, and extrudes the inner wall of the refrigerator main body 1. Since the force is mutual, the reaction force will act on the sliding door 2 to generate a pushing force, so that the sliding door 2 can be smoothly pushed open. The rubber pad 21 with a buffer air chamber installed on the outer wall of the sliding door 2 can effectively absorb and disperse the impact force, so that even if the force is too strong, the sliding door 2 will not be damaged, the convenience of daily use is improved, the damage such as glass breakage and track deformation of the sliding door 2 caused by forcibly opening the door with brute force is avoided, the maintenance cost and failure rate of the refrigerator main body 1 are reduced, and the service life of the refrigerator main body 1 is prolonged.
