Description

Electronic medal

Technical Field

The invention relates to a medal, in particular to an electronic medal.

Background

The existing medals are basically circular medal plates, each circular medal plate is provided with a hanging ring, and a medal belt penetrates through a hanging opening in the middle of the hanging ring. The medal has the advantages of simple structure, weak layering sense, single function and poor playing interest.

Disclosure of Invention

In order to solve the above problems, the present invention provides an electronic medal:

The inner wall of the ribbon connecting port is provided with a radial sliding cavity, the outer side of the sliding cavity is provided with a vent, the vent is connected with an air bag, the air bag is positioned at the back of the outer shell, and the inner side of the sliding cavity is provided with a high-pressure cavity for containing liquid carbon dioxide; the sliding cavity is internally provided with a pressure detection assembly, the pressure detection assembly comprises a sliding block and an elastic piece, the sliding block and the sliding cavity form sealed sliding fit, the middle of the sliding block is provided with a vent hole used for communicating the high-pressure cavity and the air bag, and the elastic piece is respectively connected with the bottom of the sliding cavity and used for controlling the sliding of the sliding block. Under a normal state, the slide block slides outwards due to the elastic acting force, so that the vent hole and the high-pressure cavity are staggered, and the high-pressure cavity and the air bag are isolated; when the medal falls into water, water pressure makes the slider overcome elastic force and inwards slide, and when the air vent of slider arrived the settlement position, the high-pressure chamber passed through air vent intercommunication air bag, thereby the carbon dioxide of high-pressure intracavity gasifies rapidly and makes the air bag inflation to it floats on driving the medal, avoids sinking in water.

The invention has the following beneficial effects: this product has the LED display screen for same kind of product can be according to the match category, through the different match categories of the relevant data display of input, has stronger application environment, and the LED display screen makes this product have stronger science and technology sense and interest for current product simultaneously.

Drawings

Fig. 1 is a schematic front view of an embodiment.

Fig. 2 is a schematic sectional view in the normal state of the embodiment.

Fig. 3 is a schematic cross-sectional view of an embodiment in water.

The device comprises a shell 1, a PLB circuit board 2, an LED display screen 3, a USB connector 4, a ribbon connector 5, a sliding cavity 6, a vent hole 7, an air bag 8, a high-pressure cavity 9, a sliding block 10, a vent hole 11 and an elastic element 12.

Detailed Description

The invention will be further illustrated with reference to the following examples and figures 1-3.

Example (b): the utility model provides an electronic medal, includes display module, shell body 1, display module includes interconnect's PLB circuit board 2, LED display screen 3 inlays in shell body 1 surface, PLB circuit board 2 is located shell body 1 and is equipped with the bluetooth control switch who is used for controlling LED display screen 3, the side is equipped with ribbon connector 5 on the shell body 1, and the downside is equipped with the USB connector 4 of connecting PLB circuit board 2, USB connector 4 is arranged in with data information input PLB circuit board 2. The inner wall of the ribbon connecting port 5 is provided with a radial sliding cavity 6, the outer side of the sliding cavity 6 is provided with a vent 7, the vent 7 is connected with an air bag 8, the air bag 8 is positioned at the back of the outer shell 1, and the inner side of the sliding cavity 6 is provided with a high-pressure cavity 9 for containing liquid carbon dioxide; the pressure detection assembly is arranged in the sliding cavity 6 and comprises a sliding block 10 and an elastic part 12, the sliding block 10 and the sliding cavity 6 form sealed sliding fit, a vent hole 11 for communicating the high-pressure cavity 9 with the air bag 8 is formed in the middle of the sliding block 10, and the elastic part 12 is connected with the bottom of the sliding block 10 and the bottom of the sliding cavity 6 respectively and used for controlling the sliding of the sliding block 10. Under a normal state, the slide block 10 slides outwards due to the elastic acting force, so that the vent hole 11 and the high-pressure cavity 9 are dislocated, and the high-pressure cavity 9 and the air bag 8 are isolated; when the medal falls into water, water pressure makes the slider 10 overcome the elastic force and slide inwards, when the vent hole 11 of slider 10 reached the set position, the high-pressure chamber 9 communicated the air bag 8 through the vent hole 11, thereby the carbon dioxide in the high-pressure chamber 9 gasifies rapidly and makes the air bag 8 expand, thereby it floats on driving the medal, avoids sinking in water.

This product has LED display screen 3 for same kind of product can be according to the match category, through the different match categories of input relevant data display, has stronger application environment, for example after the medal of Olympic games is cast successfully, because the typeface on the medal, consequently can't be applied to in the conventional match, and the match of various specifications and match project lin are full of the mesh, current medal can't have wider application scope, and this product can be through the display content of change display screen, thereby adapt to various matches. Simultaneously, the LED display screen 3 enables the product to have stronger scientific and technological sense and interest compared with the existing product.

Claims
