[0033] Figures 1-11 The utility model discloses a variable rail sliding door on meal vending machine, including upper and lower two support pieces, the upper and lower two support pieces all are provided with two guide slots side by side, sliding door I 5 and sliding door II 6 on corresponding inner side guide slot 3 and corresponding outer side guide slot 4 are slidingly arranged, and the top and bottom of sliding door I 5 and sliding door II 6 are all provided with the guide wheel assembly that cooperates with corresponding guide slot, the guide wheel assembly includes: multiple guide wheels 7 that are spaced apart at the top and bottom of sliding door I 5 and sliding door II 6, and the top and bottom guide wheels 7 of sliding door I 5 and sliding door II 6 are different in distribution position;

[0034] Two guide slots have a common side wall, and the side wall is provided with a plurality of openings 8 that can allow sliding door I 5 to change rail to the guide slot of sliding door II 6;

[0035] Among them, the backboard of sliding door I 5 is provided with a plurality of telescopic universal sliding plunger 9 that abuts with the one end extension of inner side guide slot 3.

[0036] Working principle:

[0037] When the sliding door of the food vending machine is in the process of opening, the sliding door I 5 and the sliding door II 6 are respectively on the corresponding inner guide groove 3 and the outer guide groove 4 of the upper support 1 and the lower support 2, and the sliding door I 5 and the sliding door II 6 are slid in the corresponding guide groove through the guide wheels 7 arranged at the top and the bottom, when the door of the food vending machine needs to be closed, the sliding door I 5 slides along the inner guide groove 3, when the guide wheels 7 at the top and the bottom match the opening 8 on the side wall of the guide groove, the spring in the retractable universal sliding plunger 9 on the back plate of the sliding door I 5 stores energy in the compressed state, when the preset condition is reached (that is, the guide wheels 7 are aligned with the opening 8), the spring releases the energy rapidly, pushes the sliding door I 5 to move outward, and makes the sliding door I 5 separate from the inner guide groove 3 and continue to slide along the outer guide groove 4. This process realizes the track change of the sliding door I 5, the sliding door I 5 and the sliding door II 6 cooperate with each other in the outer guide groove 4, and the combined width of the sliding door I 5 and the sliding door II 6 is the same as the length of the inner and outer guide grooves 4, so that the sliding door of the food vending machine is closed. When the sliding door of the food vending machine needs to be opened, the staff manually pushes the sliding door I 5 inward, the retractable universal sliding plunger 9 is compressed, the universal ball 10 is arranged at the bottom of the retractable universal sliding plunger 9, the guide wheels 7 of the sliding door I 5 move from the outer guide groove 4 to the inner guide groove 3 through the opening 8, and the staff pushes the sliding door I 5 to the length direction of the inner guide groove 3, the sliding door I 5 is smoothly moved in the inner guide groove 3 under the cooperation of the guide wheels 7 and the universal ball 10 on the retractable universal sliding plunger 9. And the position of the guide wheels 7 on the sliding door II 6 does not match the opening 8, so that the sliding door II 6 can only slide in the outer guide groove 4 and will not interfere with the sliding and track change of the sliding door I 5. Through the cooperation of the opening 8 on the guide groove, the retractable universal sliding plunger 9, the universal ball 10 and the guide wheels 7 on the sliding door I 5, the sliding door is closed in the same plane, and the airtightness between the sliding doors is improved.

[0038] In the above technical solution, the bovine eye ball 11 is arranged at the bottom of the sliding door I 5 and located beside the left and right guide wheels 7, and the pulley assembly 12 is arranged at the bottom of the sliding door II 6 and located between the guide wheels 7.

[0039] The distribution position of the bullseye roller 11 matches the position of each opening 8, and the bullseye roller 11 and the pulley assembly 12 abut the bottom surface of the corresponding guide groove. With this technical method, the distribution position of the bullseye roller 11 matches the position of each opening 8, when the guide wheel 7 of the sliding door I 5 is aligned with the opening 8 on the side wall of the guide groove, the bullseye roller 11 can also pass through the opening 8 position, without affecting the track change of the sliding door I 5, and the bullseye roller 11 forms effective contact with the bottom surface of the guide groove. The multidirectional rolling characteristics of the bullseye roller 11 can reduce friction and resistance during the sliding and track changing of the sliding door, so that the sliding door I 5 can transition more smoothly from the inner guide groove 3 to the outer guide groove 4.

[0040] The pulley assembly 12 arranged at the bottom of the sliding door II 6 also has a similar effect. The pulley assembly 12 generally includes a plurality of wheels that are evenly distributed between the guide wheels 7 and are in close contact with the bottom surface of the guide groove. During the sliding process of the sliding door II 6, the pulley assembly 12 can ensure that the contact area between the sliding door II 6 and the guide groove is evenly distributed, thereby reducing local wear and noise. This method not only improves the stability and smoothness of the sliding door during sliding, but also prolongs the service life of the sliding door and its related components.

[0041] In the above technical solution, the spatial position height of the outer guide groove 4 of the lower support 2 is lower than the height of the inner guide groove 3, and the height of the sliding door I 5 is lower than the height of the sliding door II 6, and the difference in height is the same;

[0042] The opening 8 is located on the outer side wall of the inner guide groove 3, and the outer side wall of the inner guide groove 3 and the inner side wall of the outer guide groove are located on the same horizontal plane. With this technical method, when the sliding door of the food vending machine is in the closed state, the outer guide groove 4 of the sliding door I 5, due to the spatial position height of the outer guide groove 4 of the lower support 2 being lower than the height of the inner guide groove 3, in the closed state, the sliding door I 5 will not be opened due to collision or extrusion causing the track change of the sliding door I 5, when the sliding door needs to be opened, the sliding door I 5 needs to be lifted a certain distance in the spatial height, then pushed to the opening 8 on the outer side wall of the inner guide groove 3, and the opening 8 position provides a channel for the track change, so the sliding door I 5 can smoothly enter the inner guide groove 3 along the opening 8, thereby realizing the track change and opening the sliding door.

[0043] In the above technical scheme, further comprising: a mechanical lock 13 arranged on the sliding door I 5, and the lock piece 14 inside the mechanical lock 13 abuts against the top and side wall of the outer guide groove of the upper support 1 during locking.
