[0030] The sealing plate 3 is arranged outside the slot of the vending machine 1 and can seal the slot 2 to protect the power plug and the power strip;

[0031] Among them, the cover plate 3 isolates the power plug and the reserved power cord in the slot 2. When the vending machine 1 is displaced, the power plug is stably connected to the power strip, and the reserved power cord is extended and released to make the power cord loose, thereby preventing the power plug from falling off the power strip and causing the vending machine 1 to lose power.

[0032] In order to ensure the stability of the structure of this embodiment, the sealing plate 3 is a rectangular plate, and there is an array of power cord through-holes 4 in the lower part of the sealing plate 3 for the power cord to pass through. An open through-groove is provided below the power cord through-hole 4 to facilitate the accommodation of the power cord after the power plug is electrically connected to the socket. The power cord through-hole 4 separates the power plug and seals it in the slot 2, and the power cord extends out to the power cord through-hole 4.

[0039] Since a slot 2 is provided in the notch at the lower back of the vending machine 1 and insertion holes 7 are provided at the upper and lower parts of the slot 2, the internal wires of the vending machine 1 can enter the slot 2 through the insertion hole 7 and be electrically connected to the socket strip; at the same time, the socket strip can be fixed in the corresponding position after being inserted through the mounting hole 6, and then tightened with bolts through the locking hole 5 to fix it; thus, the power plug, socket strip and the reserved power cord are hidden in the slot 2.

[0040] Since a sealing plate 3 is provided outside the notch at the lower back of the vending machine 1, and a power cord through-hole 4 with an open lower portion is provided on the sealing plate 3, when the power plug is inserted into the power strip, the sealing plate 3 can isolate the power plug in the slot 2 and close the notch at the bottom of the back of the vending machine 1. Therefore, even if the cleaning staff kicks the power cord of the power plug while cleaning, the sealing plate 3 can prevent it from being touched. The reserved power cord can effectively prevent the power strip from moving over a large range, so that the vending machine 1 will not be powered off.

[0041] The working process of this embodiment:

[0042] First, remove the cover plate 3, insert the power plug into slot 2, and insert it into the corresponding socket, leaving a power cord in slot 2;

[0043] Next, straighten the power cord on the power plug into the open slot at the bottom of the power cord through-hole 4 and slide it into the power cord through-hole 4;

[0044] Finally, install cover plate 3 to block slot 2 and isolate the power plug in slot 2.

[0045] Features of this embodiment:

[0046] The structure of the slot 2 and the cover plate 3 provided in the vending machine prevents the vending machine 1 from being powered off due to the power plug being kicked off during the cleaning process.
