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, electrocardiograph of the invention prints storehouse in conjunction with Fig. 2 and Fig. 3 comprising warehouse 1, cover board 2, printing
Component 3, rubber roller 4 and motor 5.
Warehouse 1 is fixed with electrocardiograph fuselage, is internally provided with heat-sensitive paper accommodating chamber 11, and top and side are provided with
Opening, for placing heat-sensitive paper.
Print components 3 complete the printing to heat-sensitive paper with the cooperation of rubber roller 4, specifically, rubber roller 4 is set to strip print head
It supports below 31 and mutually.In this way, rubber roller 4 rotates, the heat-sensitive paper under frictional force effect in heat-sensitive paper accommodating chamber 11 passes through glue
Between roller 4 and strip print head 31 and printed corresponding figure.The print components 3 include strip print head 31 and torsional spring
32, strip print head 31 is set to 11 top of heat-sensitive paper accommodating chamber and face heat-sensitive paper accommodating chamber 11 is arranged, 32 both ends of torsional spring point
It Gu Ding not strip print head 31 and warehouse 1.In this way, strip print head 31 can be rotated around torsional spring 32, guarantee tight with the contact of rubber roller 4
Density.Specifically, using the situation of fan-fold paper for current heat-sensitive paper, strip print head 31 is set in heat-sensitive paper accommodating chamber 11
Between position, the heat-sensitive paper of folding is provided in heat-sensitive paper accommodating chamber 11, heat-sensitive paper is across print head 31 and rubber roller.In this way,
The heat-sensitive paper of folding passes upward through strip print head 31 from intermediate position, so that its stress is more stable, rotation angle position curvature
It is smaller, prevent heat-sensitive paper to be squeezed and deformed.
Cover board 2 closes warehouse 1 and fixed rubber roller 4.Specifically, setting close to the side of paper feed port as tail portion, far from paper feed
The side of mouth is head, as shown in fig. 6, rubber roller 4 is set to 2 head of cover board and is rotatably connected therewith.As warehouse 1 and cover board
2 specific connection type, as shown in figure 4, warehouse 1 and 2 head of cover board are respectively arranged with limiting slot 12 and limit in conjunction with Fig. 5 and Fig. 6
Position block 21, limited block 21 are embedded in limiting slot 12 and roll connection, warehouse 1 and the clamping of 2 tail portion of cover board.In this way, cover board 2 is led to
It crosses 1 top of warehouse and side opening protrudes into heat-sensitive paper accommodating chamber 11, limited block 21 is located in limiting slot 12, rubber roller 4 is set
In 31 lower section of strip print head, pushes 2 tail portion of cover board and warehouse 1 is clamped, in the process, rubber roller 4 moves upwards, and jacks up strip
Print head 31, deformation occurs for torsional spring 32, so that rubber roller 4 and strip print head 31 keep being in close contact.Specifically, limiting slot 12 is
Arc groove, the limited block 21 are arc shaped slider or idler wheel.As the concrete mode that warehouse 1 and 2 tail portion of cover board are clamped, such as scheme
Shown in 6, the cover board 2 includes cover board body 20, button 22, shaft 23, spring, returning face plate 24 and hook 25,24 He of returning face plate
Hook 25 is nested in shaft 23 and fixed thereto, button 22 and the fixation of returning face plate 24, both ends of the spring fixed rotating shaft 23 and cover board
Ontology 20, shaft 23 are rotatably connected with cover board body 20, and button 22 is set to 20 surface of cover board body and consolidates with returning face plate 24
Fixed, as shown in figure 5, being provided with card slot 13 on warehouse 1, hook 25 is protruded into card slot 13 and is clamped therewith.In this way, warehouse 1 and lid
2 tail portion of plate is connected and fixed by hook 25 with card slot 13, manual depression of button 22, and returning face plate 24 drives shaft 23 and rotation, card
It hooks 25 to deviate from from card slot 13, cover board 2 can be separated with warehouse 1.Specifically, being covered in order to prevent during covering cover board 2
Plate 2 excessively pushes, and strip print head 31 is caused to generate deformation, needs to be defined the pushing displacement of cover board 2.Specifically, warehouse 1
Including sliding shoe 14, guide rod 15, supporting table 16 and elastic rod 17,1 surface of warehouse offers through slot, and sliding shoe 14 is set to logical
In slot, supporting table 16 is set to immediately below through slot and surface is provided with pilot hole, and guide rod 15 passes through pilot hole and top connects
Sliding shoe 14, elastic rod 17 is arranged in parallel with guide rod 15 and surface is fixedly connected with sliding shoe 14,17 bottom of elastic rod and support
16 surface of platform mutually supports, and 14 upper surface of sliding shoe is arc and offsets with 20 bottom surface of cover board body.In this way, pushing cover board
When 2, elastic rod 17 generates deformation, plays a supporting role to cover board 2；When opening cover board 2, elastic rod 17 restores, and rises to cover board 2
To the effect of bouncing, facilitate unlatching.
In order to guarantee that heat-sensitive paper paper delivery position is directed at strip print head 31 always, need to the position of cover board 2 and warehouse 1 into
Row precisely limit.Specifically, 20 head end of cover board body is mutually supported with 1 head inner surface of warehouse.In this way, cover board can be prevented
20 lateral compression strip print head 31 of ontology, makes its deformation.Specifically, 1 inner surface of warehouse is provided with confined planes 18 outstanding, lid
2 side of plate and confined planes 18 outstanding, mutually support, prevent the double swerve in warehouse 1 of cover board 2.
Specifically, 2 surface of cover board is inclined paper delivery inclined-plane 26, paper delivery inclined-plane 26 extends to strip print head 31 and rubber roller
Between 4.It is smoothly exported between strip print head 31 and rubber roller 4 convenient for printed heat-sensitive paper.
Specifically, further including motor 5,4 end of rubber roller is intermeshed by gear and 5 shaft of motor, motor 5 and warehouse 1
It is fixed to each other.In this way, being quickly sequentially connected with motor 5 after being installed in place convenient for rubber roller 4.
Electrocardiograph printing storehouse of the invention use process is as follows:
Installation: heat-sensitive paper is placed in heat-sensitive paper accommodating chamber 11；Cover board 2 is put into from 1 top of warehouse and side opening, is limited
Position block 21 is placed in limiting slot 12, at this point, rubber roller 4 is placed in 31 lower section of strip print head；2 tail portion of cover board is pushed, limited block 21 exists
Rotation, rubber roller 4 move upwards in limiting slot 12, jack up strip print head 31, deformation occurs for torsional spring 32, and hook 25 protrudes into card slot 13
Interior and connect and fix therewith, elastic rod 17 is squeezed deformation.
Disassembly: pressing lower button 22, and hook 25 is deviate from out of card slot 13 after overturning, while elastic rod 17 restores deformation, bounces
2 tail portion of cover board, after cover board 2 is rotated by a certain angle around limiting slot 12, connection rubber roller 4 is open from 1 top of warehouse and side together
Extraction.
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.
