Abstract
It uncaps self-locking mechanism the utility model relates to a kind of printer, including casing and hinged upper cover group on the housing, the self-locking mechanism of uncapping further includes elastic bar, and on the fixed casing of the elastic bar, and the elastic bar is equipped with protrusion；Upper cover group lower end is equipped with the fillet that the top of arc-shaped protrusion is oppressed and be connected to after the protrusion when uncapping.The utility model is realized the clamping function of upper cover group using the elasticity of elastic bar, realizes the simplification of structure, saved cost of parts and assembly cost without mechanisms such as lid-opening button, torsional spring, supports.
Description
Technical field
It uncaps self-locking mechanism the utility model relates to printer field more particularly to a kind of printer.
Background technique
Printer on the market is uncapped in order to prevent at present when changing the operation such as paper, upper cover due to gravity can automatic cover closing, it is several
All torsional spring or design support construction can be added to be supported the upper cover of printer in the hinged place of print enclosure and upper cover.Using
It is impacted when needing that corresponding lid-opening button is cooperated to use when torsional spring, and uncapping larger；And when using support construction, structure design
Cumbersome, easy break-down, manufacturing cost is more more than torsional spring structure.
Utility model content
A kind of the purpose of this utility model is to provide structures printer simple, at low cost uncaps self-locking mechanism.
To achieve the above object, the utility model uses following technical scheme:
A kind of printer is uncapped self-locking mechanism, described to uncap including casing and hinged upper cover group on the housing
Self-locking mechanism further includes elastic bar, and on the fixed casing of the elastic bar, and the elastic bar is equipped with protrusion；On described
Lid group lower end is equipped with the fillet that the top of arc-shaped protrusion is oppressed and be connected to after the protrusion when uncapping.
The elastic bar is elasticity of plastics rib.Using elasticity of plastics rib make the self-locking mechanism cost of manufacture and
Later period replacement cost is low.
The protrusion is arc-shaped.The fillet of upper cover group can be made raised in compressing using arc-shaped protrusion and convex by this
The process risen can be than smoothly.
After adopting the above technical scheme, the utility model compared with the background art, have the advantages that without uncap by
The mechanisms such as button, torsional spring, support are realized the clamping function of upper cover group using the elasticity of elastic bar, realize the simplification of structure, are saved
About cost of parts and assembly cost.
Detailed description of the invention
Fig. 1 is that the utility model is uncapped schematic diagram；
Fig. 2 is schematic diagram after the utility model is uncapped.
Specific embodiment
It uncaps self-locking mechanism as shown in Figure 1, the utility model discloses a kind of printer comprising casing 1, upper cover group 2
And elastic bar 3.Wherein, the lower end of upper cover group 2 is hinged on casing 1 by shaft 11, and lower end is equipped with fillet 21.
Elastic bar 3 is fixed on casing, and an arc-shaped protrusion 31 is equipped on elastic bar 3.When closing lid state, the lower end of upper cover group 2
Portion is not in contact with elastic bar 3.When uncapping, upper cover group 2 is rotated centered on shaft 11,2 lower end of upper cover group
Fillet 21 then 11 is rotated up around the shaft, to contact with elastic bar 3.
As shown in Fig. 2, upper cover group 2 continues to open, the fillet 21 of the lower end of upper cover group 2 can be oppressed on elastic bar 3
Protrusion 31 brings it about deformation and is opened, and then fillet 21 is connected to protrusion 31 after the protrusion 31 of elastic bar 3
Top.At this point, elastic bar 3 restores, protrusion 31 thereon forms the fillet 21 that stuck point withstands upper cover group 2, to realize upper cover
The self-locking of uncapping of group 2.
Elastic bar 3 is made of plastic cement in the utility model, and preparation cost is cheap, takes full advantage of the bullet of elastic bar 3
Property deformation realize the simplification of structure, directly replace elastic bar 3 after the abrasion of protrusion 31 on elastic bar 3, maintenance cost
It is low.
The above is only the utility model embodiment, not makees any limit to the technical scope of the utility model
System, thus any trickle amendment made by the above technical examples according to the technical essence of the present invention, equivalent variations with repair
Decorations, are still within the scope of the technical solutions of the present invention.
