Specific embodiment
Below in conjunction with embodiment of the present invention, the technical solution in embodiment of the present invention is carried out clearly and completely
Description, it is clear that described embodiment is only some embodiments of the invention, rather than whole embodiments.Base
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts all
Other embodiments shall fall within the protection scope of the present invention.
As shown in Figure 1, in conjunction with Fig. 2 and Fig. 3, electrocardiograph print components of the invention comprising removable cover 1, warehouse
2, rubber roller 3, thermal printing head 4, rack cover 5, leading cardboard 6 and rear lateral paper guide 7.
As shown in fig. 6, warehouse 2 is internally provided with heat-sensitive paper receiving cavity 21 and top is provided with opening, for being put into folding
The heat-sensitive paper folded and printed heat-sensitive paper export.Lid is located at heat-sensitive paper receiving cavity jointly for removable cover 1 and rack cover 5
In 21 top openings.Specifically, 21 bottom surface of heat-sensitive paper receiving cavity be provided with it is several it is arranged in parallel, from head rearwardly
The fin 22 that direction extends, and the height close to the height of head and tail portion fin higher than intermediate position fin.In this way, fold
Heat-sensitive paper upward, intermediate shape to lower recess in head and tail portion in heat-sensitive paper receiving cavity 21, so that adjacent temperature-sensitive
Impact direction of the paper in export is more consistent, prevents paper jam or pulls apart heat-sensitive paper.
Set 1 side of removable cover as 2 head of warehouse, 5 side of rack cover be 2 tail portion of warehouse, as shown in figure 3, temperature-sensitive
Print head 4 is fixed on 5 head of rack cover, and 1 tail portion of removable cover and rubber roller 3 are rotatably connected, and rubber roller 3 is located at thermal printing head
It supports below 4 and mutually.In this way, rubber roller 3 is caught in 4 lower section of thermal printing head when the lid of removable cover 1 is located on warehouse 2.Specifically
, rubber roller 3 is set to 21 top of heat-sensitive paper receiving cavity and is located among 2 head of warehouse and tail portion.In this way, being led from intermediate position
Heat-sensitive paper out reduces the paper feed stroke at heat-sensitive paper both ends, prevents heat-sensitive paper from wandering off.
Leading cardboard 6 is set to removable cover 1 and 3 lower section of rubber roller and fixes with removable cover 1, and rear lateral paper guide 7 is set to
4 lower section of thermal printing head is simultaneously fixed with rack cover 5, and leading 6 tail portion bottom surface of cardboard is set as arcwall face, rear 7 head of lateral paper guide
Bottom surface is set as arcwall face.In this way, to the left or heat-sensitive paper bending to the right is in the mistake by leading cardboard 6 and rear lateral paper guide 7
Cheng Zhong, the gap entered back between rubber roller 3 and thermal printing head 4 after arcwall face is rectified a deviation are printed, and printing precision can be improved.
Specifically, the rear lateral paper guide 7 includes longitudinal paper guide part 71 and lateral paper guide part 72, longitudinal paper guide part 71 is led with lateral
Paper component 72 is arranged in a mutually vertical manner and integrated molding, and longitudinal 71 side face rubber roller 3 of paper guide part is arranged and stays therebetween
There is paper feed gap, longitudinal paper guide part 71 is set as arcwall face with lateral 72 junction of paper guide part.Longitudinal paper guide part is set
71, heat-sensitive paper can be guided in one end stroke that 3 surface longitudinal of rubber roller is walked, prevent from wandering off.Specifically, leading cardboard 6
Head bottom surface and 7 tail portion bottom surface of rear lateral paper guide up warpage.In this way, two adjacent heat-sensitive papers during paper feed, have more greatly
Space of saving, prevent heat-sensitive paper from wandering off.
Specifically, 1 tail portion upper surface of removable cover is bent down, extends to rubber roller 3 and thermal printing head 4 supports gap
Place.On the one hand, 1 tail portion of removable cover and 6 tail portion of leading cardboard are bent downwardly together, can save space；On the other hand, removable cover
1 tail portion upper surface of plate can be used as inclined-plane derived from guidance heat-sensitive paper.
In order to improve the positioning accuracy of heat-sensitive paper, need to improve the positioning accuracy of removable cover 1 Yu warehouse 2.Specifically, such as
Shown in Fig. 4, moves 1 tail portion of cover board and the prominent tip 11 is set, the stage portion 23 of recess, prominent 11 side of the tip are provided on 2 two sidewalls of warehouse
Face and the side of stage portion 23 offset.In this way, can be limited in cephlad-caudal and up and down direction to removable cover 1.
Specifically, warehouse is set on 2 two sidewalls as shown in figure 5,1 two sides of tail of removable cover is provided with arc-shaped limit block 12
It is equipped with arc limit slot 24, arc-shaped limit block 12 is embedded in arc limit slot 24 and slides axially therewith or axial rolling company
It connects.Arc-shaped limit block 12 and arc limit slot 24 are set, and removable cover 1 is when being packed into, around 12 axis rotation of arc-shaped limit block, glue
Roller 3 jacks up thermal printing head 4 upwards, will not apply lateral pressure to thermal printing head 4 or rear lateral paper guide 7, prevent to heat
The positioning of quick print head 4 causes to be displaced, and improves printing precision.Specifically, 12 side of arc-shaped limit block and 24 side of arc limit slot
Face mutually supports.In this way, can limit in the lateral direction to removable cover 1, prevent removable cover 1 from left and right displacement.
Specifically, 1 head of removable cover and 2 head of warehouse are clamped.
The foregoing is merely better embodiments of the invention, are not intended to limit the invention, all of the invention
Within spirit and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
