Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments, and the following embodiments are used for illustrating the present invention, but do not limit the scope of the present invention.

Referring to fig. 1 to 7, the embodiment of the utility model provides a thermal bill printer, including center 1 and set up in base 2 of center 1 below, be provided with cell body 3 on the inner wall of center 1's back lateral wall, the opening of cell body 3 is down, and the embedding has external loudspeaker 5 in the cell body 3, and the rear side of base 2 has shutoff cell body 3 open-ended extension board 4 down, and the peripheral edge of the external loudspeaker 5 of upper surface edge butt of extension board 4 prevents that external loudspeaker 5 from droing from center 1. Wherein the front-to-back direction is the direction indicated by the arrows in fig. 1-3.

Adopt the embodiment of the utility model provides a temperature sensing bill printer, simple structure, the assembly of external loudspeaker is simple, and it is fixed to need not the screw or do the plastic accessory more and go the assembly, and operating time is short, reduces assembly cost to improve production efficiency.

In order to fix the external horn 5 more reasonably, a slot 6 for accommodating a magnet of the external horn 5 is formed on the opening of the groove body 3. The magnet of the external loudspeaker 5 is arranged on the open slot 6 of the groove body 3, so that the assembly space is more reasonably utilized.

In order to further fix the external horn 5, limiting ribs 7 for clamping the external horn 5 are arranged at two sides of the slot 6 in the groove body 3. Set up spacing muscle 7 through the cell body 3 and carry out the chucking to external loudspeaker 5 fixed, the die sinking is simple, easily realizes, preparation low cost to the chucking is respond well.

In a preferred embodiment, a shockproof sponge 8 pad is arranged on the bell mouth of the external horn 5. In this embodiment, the anti-vibration sponge 8 pad is glued to the bell mouth of the external horn 5. Furthermore, the horn mouth of the external horn 5 faces to one side opposite to the open slot 6 in the slot body 3, and a sound transmission hole 9 communicated with the outside is formed in the slot body 3.

As a preferred embodiment, a rubber pad 13 is disposed on the bottom of the base 2, and a groove 10 for accommodating the rubber pad 13 is disposed on the bottom of the base 2. Furthermore, screens 11 arranged oppositely are arranged in the groove 10, via holes 12 for the screens 11 to be buckled are arranged on two sides of the rubber mat 13, the rubber mat 13 is buckled through the screens 11 arranged oppositely in the groove 10, and therefore the rubber mat 13 is fixed without adopting fixing tools such as screws and the like, and the assembly is simple and time-saving.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
