AUTOMATIC VENDING MACHINE

An automatic vending machine includes a front door, a thermal insulation door, and a latching member. The thermal insulation door is rotatably secured to the front door. The latching member is secured to the thermal insulation door and engages with the front door to prevent the thermal insulation door from rotating relative to the front door, so that the thermal insulation door is secured to the front door without screws.

DETAILED DESCRIPTION

Referring toFIG. 1, an automatic vending machine includes a front door30, a thermal insulation door50, and a latching member70.

In this embodiment, the front door30includes a front plate31, a first side plate33, and a second side plate35. The first side plate33and the second side plate35are located at opposite sides of the front plate31. The first side plate33and the second side plate35are substantially parallel to each other and substantially perpendicular to the front plate31. A blocking portion331(shown inFIG. 6) is located on the first side plate33. The blocking portion331includes a resisting piece3311extending from the first side plate33, and a blocking piece3313extending from the resisting piece3311. The resisting piece3311is substantially perpendicular to the first side plate33, and the blocking piece3313is substantially perpendicular to the resisting piece3311and parallel to the first side plate33. Three hinges351are located on the second side plate35, to secure the thermal insulation door50.

The thermal insulation door50has a substantially rectangular cross-section and includes a first sidewall51and a second sidewall53opposite to the first sidewall51. A width of the thermal insulation door50is slightly smaller than a distance between the first side plate33and the second side plate35.

FIGS. 2-3show that the latching member70includes a securing piece71, a resilient piece73, a latching portion75, and an actuating piece77. In this embodiment, the securing piece71is secured to the thermal insulation door50by screws. The resilient piece73extends from the securing piece71. An obtuse angle is formed between the securing piece71and the resilient piece73. The latching portion75includes a latching piece751and a limiting piece753. The latching piece751extends from the resilient piece73. An acute angle is formed between the latching piece751and the resilient piece73, and the latching piece751is substantially parallel to the securing piece71. The limiting piece753extends from the latching piece751. The limiting piece753is perpendicular to the latching piece751and the securing piece71, and an acute angle is defined between the limiting piece753and the resilient piece73. The actuating piece77extends from the limiting piece753. The resilient piece73and the limiting piece753are arranged at opposite sides of the latching piece751. The latching piece751and the actuating piece77are arranged at opposite ends of the limiting piece753.

FIGS. 4-5show that in assembly, the thermal insulation door50is rotatably secured to the front door30by securing the three hinges351to the second sidewall53and the front door30. The securing piece71is secured to the first sidewall51of the thermal insulation door50via fasteners. At this position, an acute angle is defined between the first sidewall51and the resilient piece73, and the latching piece751is perpendicular to the first sidewall51. To close the thermal insulation door50, the actuating piece77is pushed by a user to resiliently deform the resilient piece73toward the first sidewall51. The thermal insulation door50is rotated along a first direction until the latching piece751extends past the blocking portion331. Then, the actuating piece77is released, and the resilient piece73resiliently rebounds, so that the latching potion75engages with the blocking piece3313to prevent the thermal insulation door50from rotating relative to the front door30.

To open the thermal insulation door50, the actuating piece77is pushed so that the latching portion75disengages from the blocking piece3313. The thermal insulation door50is rotated along a second direction opposite to the first direction to open the thermal insulation door50.
