Background technique

In the fields of retail, catering, ticket sales, etc., computers are required for display, purchase and other operations. For example, in catering sales, consumers need to be shown and selected to buy. For example, the existing restaurants generally use display screens at high places for display and require an independent host for control. The host and display screens are independently set on the counter top, and the service personnel operate and purchase. This method requires two independent displays and hosts, and requires additional service personnel to operate.

The second cylinder 30 is fixedly arranged in the cabinet 00 to drive the push plate 31 to move; the gear 32 is fixed coaxially on the support shaft 131 away from the rotating body At one end of 10, the push plate 31 is arranged vertically and a rack is provided at the lower part, and the rack is matched with the gear 32;

The switching device has at least a first working state and a second working state;

When in the first working state, the second air cylinder 30 shrinks, the rack and the gear 32 are disengaged, and when the first air cylinder 20 moves, it drives the rotating body 10 to move up and down;

When in the second working state, the second air cylinder 30 is extended to drive the push plate 31 to approach the gear 32, and when the first air cylinder 20 drives the rotating body 10 to move upward, the rotating body 10 first rotates 120° and then moves vertically upward by a thickness A When the first cylinder 20 drives the rotating body 10 to move down, the rotating body 10 vertically moves down a distance of thickness A and then rotates 120°.

When working, when the computer needs to be used, the second cylinder 30 is controlled to retract, so that the second cylinder 30 drives the push plate 31 to move backward, so that the gear 32 cannot be meshed with the rack, and the first cylinder 20 is activated to make the first cylinder 20 Drive the rotating body 10 to move up (assuming the display screen 11 is at the top at this time), the first air cylinder 20 drives the rotating body 10 to move up, the rotating body 10 does not rotate during the upward movement, and the display screen 11 enters the storage hole, and the storage hole In cooperation, the upper end surface of the display screen 11 and the work surface are in the same plane, which is convenient for operation and display.

Embodiment 2:

In the first embodiment, since the support shaft 131 is located at the center of gravity of the cross section, it is difficult to keep the gravity of the storage board 12 and the display screen 11 constant. The body 10 is deflected so that the display screen 11 cannot be accurately matched with the receiving hole, resulting in damage to the display screen 11. Therefore, in this embodiment, the outer casing 13 is extended on both sides of the rotating body 10, and the outer casing 13 is a hollow structure. 3, that is, the inside of the outer box 13 is also a triangular cavity, and the support shaft 131 is fixedly arranged on the outer box 13; the outer box 13 is provided with a gravity ball 14, and the gravity ball 14 is freely arranged outside Inside the box 13;

During operation, when the rotating body 10 is turned over, since the triangular cavity has three inflection points, the gravity ball 14 will slide to any inflection point with the overturning of the rotating body 10 under the action of gravity, because the gravity ball 14 is heavier. , the position of the gravity ball 14 is always lower than the rotation center of the rotating body 10, so the rotating body 10 can be arranged in an inverted triangle shape in different postures as much as possible, even if the display screen 11 or the storage board 12 can maintain a precise position match with the storage hole, reducing the possibility of the display screen 11 or the storage board 12 being damaged.

Embodiment three:

On the basis of the second embodiment, there are certain deviations in the manufacture of the equipment, which will lead to the cheapness of the center of gravity (including the weight of other internal equipment may also cause the center of gravity to shift), and this offset will cause the rotation body 10 to be small. This deflection will also cause the display screen 11 or the storage board 12 to not be accurately matched with the storage hole. Therefore, in this embodiment, as shown in FIG. 2 , the two sides of the rotating body 10 are extended with outer boxes. 13. The outer box body 13 is a hollow structure, and the support shaft 131 is fixedly arranged on the outer box body 13; the outer box body 13 is provided with a gravity ball 14, and the gravity ball 14 is freely arranged in the outer box body 13;

The upper ends of the display screen 11 and the storage board 12 are both trapezoidal in structure, and the cross-section of the receiving hole is also in the trapezoidal structure and is matched with the upper ends of the display screen 11 and the storage board 12 .

The trapezoidal structure forms a guiding role in the process of gradually matching the display screen 11 or the storage board 12 with the storage hole, and the upper end of the display screen 11 or the storage board 12 is folded inward. In the case of deflection, the lower end of the storage hole is larger, It can provide a larger fault tolerance space. During the contact between the smaller end and the larger space, it will be gradually adjusted under the guidance of the inclined plane, reducing the possibility of damage.
