Abstract
A kind of cover-opening structure of printer, it is closed in the printer upper casing for opening and covering with printer lower casing, including universal driving shaft, it is fixed on the discount at the universal driving shaft both ends, it is equipped with torsional spring bracket on the universal driving shaft and close to discount position described in one, reduction torsion spring is connected on the torsional spring bracket and is rotatablely connected with the universal driving shaft.Using simple mechanical structure, the state of folding is realized by the discount of reset tension spring active force by slider control, one hand can be operated, and it is easy to use, it is more in line with ergonomics.
Description
Technical field
The utility model relates to printer technology fields, and in particular to a kind of cover-opening structure of printer.
Background technique
In the folding lid mode of printer, existing is essentially all that both hands to be used are operated, this traditional
Unfolding mode is relatively inconvenient.
Utility model content
Based on the deficiencies of the prior art, the purpose of this utility model is to provide a kind of cover-opening structure of printer, structures
Simply, practical, one-handed performance uses easy.
To achieve the above object, the technical solution of the utility model are as follows:
A kind of cover-opening structure of printer is located in the printer upper casing and closes for opening and covering with printer lower casing,
Including universal driving shaft, it is fixed on the discount at the universal driving shaft both ends, is set on the universal driving shaft and close to discount position described in one
There is torsional spring bracket, reduction torsion spring is connected on the torsional spring bracket and is rotatablely connected with the universal driving shaft.
Further, the cover-opening structure is installed on inside the printer upper casing, and the discount is protruded from into institute
State printer upper casing bottom surface.
Further, position corresponding with the discount is equipped with card slot on the printer lower casing, and Gai Heshi is described
Discount is interlocked with the card slot.
Further, slider detent is offered in the lateral location of the card slot, is had in the slider detent slidable
Push button, spring is provided on the position opposite with the push button pushing direction, and the spring connects the push button and the printing
Machine lower casing.
Further, on the direction of promotion, the push button is mutually touched with the discount.
The utility model has the following beneficial effects: being made by slider control by reset tension spring using simple mechanical structure
Discount firmly realizes the state of folding, and one hand can be operated, easy to use, is more in line with ergonomics.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the installation diagram of the utility model assembly on a printer.
Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the utility model, specific structure and generation
It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field
Art personnel other embodiments obtained without creative efforts belong to the model of the utility model protection
It encloses.
It is as shown in Figs. 1-2: a kind of cover-opening structure of printer, be located in the printer upper casing 1 for under printer
Shell 2 is opened and lid closes, including universal driving shaft 3, is fixed on the discount 4 at 3 both ends of universal driving shaft, on the universal driving shaft 3 and close
4 position of discount described in one is equipped with torsional spring bracket 5, be connected on the torsional spring bracket 5 reduction torsion spring 6 and with the universal driving shaft 3
Rotation connection.The discount 4 is fixedly connected on the both ends of universal driving shaft 3, and in the utility model, the spring support 5 is located at the right side
It at the discount 4 at end, and can be rotated along the universal driving shaft 3, the reduction torsion spring 6 is placed on the torsional spring bracket 5, and one
End is stuck on the salient position of the torsional spring bracket 5, and when stress can carry out elastic reset variation.
The cover-opening structure is installed on inside the printer upper casing 1, and the discount 4 is protruded from into the printer
1 bottom surface of upper casing.The length of utility model after assembling is adapted with the size inside printer upper casing 1, and be rotatablely installed in
Inside printer upper casing 1, meanwhile, the 5 top salient position of torsional spring bracket is fixedly connected on inside printer upper casing 1.
In addition, position corresponding with the discount 4 is equipped with card slot 7, Gai Heshi on the printer lower casing 2, it is described
Discount 4 is interlocked with the card slot 7.The size of the card slot 7 is greater than the size of the discount 4, Gai Heshi, and the discount 4 is worn
It crosses the card slot 7 to fasten by hook part, completes the state that lid closes.
Slider detent 8 is offered in the lateral location of the card slot 7, there is slidable push button 9 in the slider detent 8,
Spring 10 is provided on the position opposite with 9 pushing direction of push button, the spring 10 connects the push button 9 and the printing
Machine lower casing 2.On the direction of promotion, the push button 9 is touched with 4 phase of discount.When it is described push away girl 9 slide when, it is described
Elastic force is put in the elongation of spring 10 to good use, meanwhile, the push button 9 pushes the discount 4, drives described in the rotation of universal driving shaft 3 triggering
Spring-compressed energy storage state occurs for reduction torsion spring 6, and therefore, the discount 4 is detached from the card slot 7, and lower casing is beaten on the printer
It opens；The push button 9 is unclamped, automatic 10 pulling force of spring of receiving automatically resets, and the universal driving shaft 3 and discount 4 are by the reduction torsion spring 6
It resets and resets；Operating process only carries out with a finger, simple and convenient, reasonable utilization ergonomics, practical.
Utility model has the advantages that
The utility model has the following beneficial effects: being made by slider control by reset tension spring using simple mechanical structure
Discount firmly realizes the state of folding, and one hand can be operated, easy to use, is more in line with ergonomics.
It is the preferred embodiment of the utility model it should be noted that described above, the utility model not office
It is limited to above embodiment, as long as its technical effect for reaching the utility model with identical means, it is practical new all should belong to this
The protection scope of type.
