Abstract
The utility model discloses a cover opening mechanism for a bill printer, which comprises pressing keys, a main body and springs, wherein the main body is fixed with a double cylindrical guide bar in a longitudinal direction. Both ends of the pressing key are provided with a guide hole, and the springs are sheathed on the double cylindrical guide bar. One end of the springs away from the pressing key is fixed. The guide hole of the pressing key is in an interstice match with the cylinder guide bar. The pressing key can move up and down along the cylinder guide bar. A locking mechanism is driven by a convex part structure in the middle of a pressing key component to open a machine cover. The utility model has the advantages of simple structure, few components, easy fabrication and little occupying area. The utility model is installed on the bill printer, can ensure a favorable opening of the machine cover of the bill printer and can also be applied to the opening of the other machine covers simultaneously.
Description
Technical field
The utility model relates to a kind of cap-opening mechanism of bill printer.
Background technology
In the bill printer, printing paper is contained in the machine, printing paper adorns paper, need apparatus lid opening when changing operation such as paper, therefore, need the design cap-opening mechanism, existing bill printer cap-opening mechanism is made of complicated mechanism assembly usually, and not enough place is: mechanism's complexity, manufacturing expense height, take up space bigger.
The utility model is simple in structure, easily manufactured.On bill printer, install, but the smooth unlatching of the cover of backed bill printer, constituting cleverly with the print head assembly of standard, cap-opening mechanism is adapted at using on the bigger bill printer in print head assembly space, because the ingenious characteristics of utilizing working of plastics to be easy to make the guide pillar structure, under the prerequisite that guarantees service property (quality), reduce manufacturing expense.
Summary of the invention
The utility model adopts and is led by two guide pillars, and the method that button spare moves along two guide pillars is determined moving up and down of button spare exactly.
Bill printer cap-opening mechanism described in the utility model, comprise button 1, main body 2, spring 3, vertical fixedly bicylindrical guide post on the described main body 2, respectively there is a pilot hole at described button 1 two ends, be set with spring on the described bicylindrical guide post, spring is fixed away from an end of button, and the pilot hole of described button and described cylinder guide post are matched in clearance, button can move up and down along the cylinder guide post, opens cover by the protuberance structure drive retaining mechanism at button spare middle part.
There is a screw at described bicylindrical guide post center, and trip bolt is housed in the screw, and trip bolt adds Upper gasket to be fixed described spring.
A described bicylindrical guide post wherein column dimension is short than another, adopts the self tapping tapping screw fastening, wherein than short column add grow to another post contour.
The same length of described bicylindrical guide post.
Above-mentioned button 1, main body 2 bicylindrical guide post parts can adopt metal material or engineering plastic materials manufacturing.
Accompanying drawing 1-5 represents the operation principle of cap-opening mechanism.Its course of work is such: the bicylindrical on the main component is the button guiding that moves up and down, and bicylindrical cooperates with the interporal lacuna at button two ends.Bicylindrical mesopore is the fastener hole of screw.Button spare is made of two pilot holes and opening structure, and pilot hole moves up and down along lead, links by hole and opening structure and mechanism, opens cover, and the restoring force of button is two spring forces.Trip bolt adds Upper gasket to be fixed an end of spring.
Button spare when work, to press and be the cover breakdown action, the normality position is for replying the position.
The utility model is simple in structure, and part is few, and is easily manufactured, and it is few to take up space, on bill printer, install, but the smooth unlatching of the cover of backed bill printer.Can also use in the unlatching of other covers simultaneously.

The specific embodiment
Accompanying drawing 8 has been described the utility model---an embodiment of two guide pillar cap-opening mechanisms.
Embodiment structure of the present utility model is made up of button 1, main body 2, spring 3, screw 4, pad 5 etc.
Structure of the present utility model is assembling like this: when button spare was pressed, button spare two ends moved downward along two guide pillars by the guiding trepanning, opened cover by the protuberance bit architecture drive retaining mechanism at button spare middle part.Resetting of button spare replied by two spring forces, and trip bolt adds Upper gasket to be fixed spring.
Mechanism of the present utility model is like this work: the bicylindrical on the main component is the button guiding that moves up and down, and bicylindrical cooperates with the interporal lacuna at button two ends.Bicylindrical mesopore is the fastener hole of screw.Button spare is made of two pilot holes and opening structure, and pilot hole moves up and down along lead, links by hole and opening structure and mechanism, opens cover, and the restoring force of button is two spring forces.Trip bolt adds Upper gasket to be fixed an end of spring.
Button spare when work, to press and be the cover breakdown action, the normality position is for replying the position.
It is relevant with the length of twin columns to open distance, and the compression total length L of L1 spring is relevant, opens length L=L1-t-L2, and L1 is the length of pilot hole, and L2 is a spring compression back length.Open length and determined by the distance of opening movement, this structure L1 under the prerequisite that guarantees L will lack as far as possible.
For attractive in appearance, can consider to add a gusset on the main component at button limit opposite side.
The position that this cap-opening mechanism is simple in structure, structural member takes up space is little.During installation, twin columns mechanism is because button spare will be packed into, and a column dimension will be lacked.Trip bolt adopts tapping screw, and one of them will add long column, guarantees two post operating position unanimities.
