Description

Rotatable luminous menu board

Technical field:

The utility model relates to the technical field of signs, in particular to a rotatable luminous menu card.

Background technique:

In order to display more menu information and advertisements, a kind of menu holder with multi-face display has appeared in the restaurant, such as the Chinese patent "a menu holder" (patent No.: 200620060405.5), its menu holder consists of two A group of parallel vertical boards, the number of groups is not limited, there is a gap between the boards, the other vertical side of all the vertical boards are connected together, the overall distribution is radial, each group of parallel vertical boards and adjacent vertical boards The angles between the boards are equal, and the middle space of each set of vertical boards can be inserted into a menu or recipe, which increases the amount of information dissemination. However, each set of vertical boards is fixed. When customers need to check the menu on the other side, they need to turn the entire menu clip, which is not convenient; The lighting problem makes it difficult to see the text on the menu. In many western restaurants or KTVs, the waiters will bring their own flashlights, writing pens with lights or use external lights when ordering, which is very inconvenient; in addition, in noisy KTVs In environments such as DISCO or DISCO, it is also very difficult to remind the waiter to serve. First, the environment is dark, and it is difficult for the waiter and the customer to recognize each other. At the same time, it is difficult to greet each other in a noisy environment. There used to be a server with an alarm, but the server At the main station, waiters have to wait for the waiters to return to the main station before rushing to serve customers, and in a noisy environment, the function of the alarm can not be brought into play.

Utility model content:

The purpose of this utility model is to provide a rotatable light-emitting menu board for the shortcomings of the existing technology, which solves the defect that the existing multi-faceted menu board cannot be rotated, and can emit light in a dark environment, and overcomes the inability to rotate in a dark environment. Insufficient to see clearly the text of the menu, it also has the function of light reminder, to overcome the inadequacy of not being able to ask the waiter for service in a noisy environment.

In order to achieve the above object, the technical solution adopted by the utility model is: it includes a base and a rotating shaft standing on the base, and at least three sets of clamping frames are arranged on the rotating shaft, and the clamping frame includes an upper splint and a lower splint, and an upper splint and a lower splint. There are limited grooves on the opposite sides of the splint, which are characterized in that: a light-transmitting plate is clamped between the upper splint and the lower splint, and a light-emitting diode is arranged inside the lower splint; a power supply, a motor and a speed reduction mechanism are installed inside the base, and the motor The output shaft of the deceleration mechanism is connected with the deceleration mechanism, and the output end of the deceleration mechanism is connected with the rotating shaft; the top of the rotating shaft is also provided with an indicator light for serving as a reminder; the power supply, the light-emitting diode and the main power switch form a circuit, and the power supply , the main power switch, the service prompt switch and the indicator light form a loop, and the power supply, the main power switch, the motor switch and the motor form a loop.

The included angles between the three groups of clamping frames are equal.

A step-down diode is connected in series between the power supply and the light emitting diode.

The three groups of light-emitting diodes inside the lower splint are connected in parallel to the circuit.

In the loop formed by the power supply, the main power switch, the service reminder switch and the indicator light, the indicator light is connected in parallel with a capacitor.

In the circuit composed of the power supply, the main power switch, the motor switch and the motor, the motor is connected in parallel with a capacitor.

The power supply is a rechargeable lithium battery, and the side of the base is provided with an in-line charging jack, and the positive and negative poles passing through the in-line charging jack are respectively connected to the positive and negative poles of the rechargeable lithium battery through wires.

The beneficial effect of the utility model is: because the motor-driven rotating shaft is installed in the base, the rotating shaft can rotate freely, and customers can see the menus placed at different angles by simply pressing the button without rotating the entire menu board. Convenient; in addition, the lower splint of the clamping frame of the utility model is provided with a light-emitting diode, and the light is irradiated on the light-transmitting plate, and the menu clamped on the clamping frame can be clearly seen even in a dark environment; There is also an indicator light on the top, which can be set to glow red. As long as the indicator light is turned on, it can send a reminder to the waiter that service is needed, which is convenient for effectively reminding the waiter in a noisy environment and avoiding unnecessary troubles.
