Abstract

The utility model discloses a micro printer comprising a door cover, a printing head roller, a rotating shaft, a button, a housing body, a printing head, a circuit board, a side plate, a first rear cover, and a second rear cover. The micro printer also comprises fixing clamps which are clamped on guide rails in the housing body. The fixing clamps with U-shaped structure are produced by elastic material.

Description

Mini-printer

Technical field

The utility model relates to the printer field, in particular to a kind of mini-printer.

Background technology

In the fixed installation to whole mini-printer, the fixed card of using in the market in the guide rail of housing without any damping, because the mini-printer installing space is narrow and small, easily come off, therefore require installation rate very fast and must have two people to cooperate when installing, the problem that fixed card comes off often appears in single installation.

And at present the paper door of mini-printer is installed, adopt traditional hard card to enter more or door and housing between be connected with metal shaft.For the door connected mode following shortcoming is arranged:

1, adopt metal shaft to connect, increased material cost, increased installation steps, increased human cost, improved the manufacturing cost of complete machine, die cost also will increase simultaneously.

2, enter to install for hard card, because door-hinge place limited space, it is too sturdy that axle can not be done, and easily damages the fixed axis of door both sides during dismounting, causes whole plastic casing to be scrapped.Because accessory damages, increase the difficulty of producing batching, improved management cost.Hard card enters structure and must just can snap in larger power, and larger power is easier to damage, and exerts oneself littlely then not fill, and must have the special messenger that this gadget is installed, and has increased production cost, has reduced installation effectiveness.

The utility model content

The utility model provides a kind of mini-printer, in order to overcome the above-mentioned problems in the prior art.

For achieving the above object, the utility model provides a kind of mini-printer, and it comprises: door closure, printhead roller bearing, rotating shaft, button, housing, printhead, circuit board, side plate, the first bonnet and the second bonnet also comprise:

Fixed card is fastened in the guide rail of housing, and it is the U-shaped structure of elastic material.

Further, the both sides that door closure snaps in housing are respectively arranged with spring contact, and door closure is by spring contact and housing clamping.

In above-described embodiment, when whole mini-printer being fixed installation, the fixed card of elastic material has increased damping at original architecture basics, in the guide rail of housing, there is not certain external force can not come off easily, therefore, the client can a people easily finish installation, the installation effectiveness of Effective Raise mini-printer when mounted.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the mini-printer explosive view of the utility model one embodiment;

Fig. 2 is the front view of Fig. 1 embodiment mini-printer;

Fig. 3 is the sectional view along A-A of Fig. 2 embodiment mini-printer;

Fig. 4 is the sectional view along B-B of Fig. 2 embodiment mini-printer;

Fig. 5 is the left view of Fig. 1 embodiment mini-printer.

The specific embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not paying the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.

Fig. 1 is the mini-printer explosive view of the utility model one embodiment; Fig. 2 is the front view of Fig. 1 embodiment mini-printer; Fig. 3 is the sectional view along A-A of Fig. 2 embodiment mini-printer; Fig. 4 is the sectional view along B-B of Fig. 2 embodiment mini-printer; Fig. 5 is the left view of Fig. 1 embodiment mini-printer.As shown in the figure, this mini-printer comprises: door closure 1, printhead roller bearing 2, rotating shaft 3, little paper roll 4, large paper roll 5, button 6, housing 7, printhead 9, circuit board 10, side plate 11, the first bonnet 12 and the second bonnet 13 also comprise:

Fixed card 8 is fastened in the guide rail of housing 7, and it is the U-shaped structure of elastic material.

When whole mini-printer being fixed installation, the fixed card of elastic material has increased damping at original architecture basics, in the guide rail of housing, there is not certain external force can not come off easily, therefore, the client can a people easily finish installation, the installation effectiveness of Effective Raise mini-printer when mounted.

In Fig. 1, the both sides that door closure 1 snaps in housing 7 also are respectively arranged with spring contact (as adopting plastic material), door closure 1 is by spring contact and housing 7 clampings, namely enter the both sides increase elastic mechanism of housing at former door closure hard card, by the distortion of plastics, can very easily finish installation, and required power is less when installing, install simply, the workshop any staff all can install, and is not prone to the accident that fractures.And owing to having increased plastic deformation mechanism (spring contact), when repair demolition, need only do a point deformation to working of plastics with screwdriver, and get final product easy removal, avoid occurring the accident of fractureing.

One of ordinary skill in the art will appreciate that: accompanying drawing is the schematic diagram of an embodiment, and the module in the accompanying drawing or flow process might not be that enforcement the utility model is necessary.

One of ordinary skill in the art will appreciate that: the module in the device among the embodiment can be described according to embodiment and be distributed in the device of embodiment, also can carry out respective change and be arranged in the one or more devices that are different from the present embodiment.The module of above-described embodiment can be merged into a module, also can further split into a plurality of submodules.

It should be noted that at last: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that previous embodiment is put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of the utility model embodiment technical scheme.
