The specific embodiment
In order to describe structure of the present utility model and characteristics places in detail, hereby lift following preferred embodiment and also coordinate description of drawings as follows.
Referring to Fig. 1 and Fig. 2, printer embodiment of the present utility model roughly comprises: chassis body 1, upper cover 2, be installed in the first head section 3 on this chassis body 1, be installed in the second head section 4 on this upper cover 2, in order to the connecting plate 5 that this second head section 4 is connected together with this upper cover 2, be installed on this second head section 4 and stretch out in the handle 6 of this upper cover 2, in order to the extension spring 7 of regulating this upper cover 2 and this chassis body 1 open configuration and in order to be connected the rotating shaft 8 of this first head section 3 and this second head section 4.By operating this handle 6, this upper cover 2 and the second head section 4 can rotate a certain angle around this chassis body 1 and the first head section 3.
This extension spring 7 is installed in the rear portion of this upper cover 2, and namely near the position of rotating shaft 8, it has first end 71 and the second end 72, and first end 71 connects this chassis body 1, the second end 72 and connects this upper casing 2.Wherein, referring to Fig. 1, this extension spring 7 is in free state when relative this chassis body 1 of this upper cover 2 is closed; Referring to Fig. 2, when this extension spring 7 is opened fully at relative this chassis body 1 of this upper cover 2, be in extended state, open fully to keep relative this chassis body 1 of this upper cover 2.
Referring to Fig. 3 and Fig. 4, this second head section 4 comprises lateral paper guide 41 and two stage clip mechanisms 43.These two stage clip mechanisms 43 are installed on this upper cover 2 in order to push down upper lateral paper guide 41, can be used to regulate the frictional force between feed roller and pinch roller and printing paper.Each stage clip mechanism 43 comprises the stage clip 433 that the guide pin bushing 431, the telescopically that are installed on this upper cover 2 are installed in the guide pillar 432 in this guide pin bushing 431 and match with this guide pillar 432.This guide pillar 432 can stretch out in this guide pin bushing 431 and with this on lateral paper guide 41 support mutually.Particularly, this guide pin bushing 431 is the hollow cylinder shape, and its end of lateral paper guide 41 on this is provided with perforate and stretches out for this guide pillar 432.This guide pillar 432 comprises a cylindrical main body 4321 and a protuberance 4322 that radially stretches out at the middle part of this main body 4321.The outline bore of this main body 4321 is less than the bore of the perforate of this guide pin bushing 431, the outline bore of this protuberance 4322 is greater than the bore of the perforate of this guide pin bushing 431 and less than the interior profile bore of this guide pin bushing 431, this structure, make guide pillar 432 to move in guide pin bushing 431, again can not from this guide pin bushing 431 towards this on an end of lateral paper guide 41 escape from.This stage clip 433 is enclosed within on the main body 4321 of this guide pillar 432, the bore of this stage clip 433 is slightly larger than the outline bore of main body 4321 and less than the outline bore of this protuberance 4322, one end of this stage clip 433 and protuberance 4322 of this guide pillar 432 is supported, the other end and this upper cover 2 are supported, this structure, can make stage clip 433 carry out elasticity by 2 pairs of these guide pillars 432 of upper cover supports, and then on the whole, make stage clip mechanism 43 to produce suitable active forces to lateral paper guide on this 41.In the present embodiment, this upper cover 2 respectively is provided with a described stage clip mechanism 43 at the place, close two ends of its width.This structure can guarantee in the process of paper feeding, and the both sides of upper lateral paper guide 41 are stressed evenly.In other embodiment, according to the actual conditions of the width dimensions of lateral paper guide 41 on upper cover 2/, can be only in one of centre installing stage clip mechanism 43, can be also the stage clip mechanism 43 that roughly installs equably more than three and three.The assembling process of stage clip mechanism 43 roughly comprises; Guide pillar 432 is packed in guide pin bushing 431, and makes one section of guide pillar 432 to pass from the corresponding perforate of guide pin bushing 431, then with compression spring sleeve 433 on the main body 4321 of this guide pillar 432; At last, make the another end of stage clip 433 support this upper cover 2, guide pin bushing 431 is attached to this upper cover 2 by securing member.The operation principle of stage clip mechanism 43 is roughly: be subjected to the used time of doing of printing paper when upper lateral paper guide 41, guide pillar 432 is stressed, can make stage clip 433 be subjected to force compresses, and guide pillar 432 can 2 place directions move suitable distance along guide pin bushing 431 inwalls to upper cover; When the effect of printing paper reduces or disappears, the external force that acts on guide pillar 432 can correspondingly reduce or disappear, under the restoring force effect of stage clip 433, guide pillar 432 can move along the guide pin bushing 431 inwalls lateral paper guide 41 place directions that make progress, in whole process, guide pillar 432 is stressed evenly, and is steadily mobile.This structure by installing stage clip mechanism on upper cover 2 43, makes the feeder assembling simple, and compact conformation, attractive in appearance.
The operation principle of printer embodiment of the present utility model roughly comprises: due to the Action of Gravity Field that is subject to upper cover 2 and the second head section 4, in the situation that without any external force, on upper cover 2 and the second head section 4 meeting automatic covers, and the purpose of opening upper cover 2 is in the situation that paperboard etc. to occur bad, the maintenance work of fixing a breakdown.In this maintenance process, upper cover 2 can not autoshutdown.Referring to Fig. 1, when upper cover 2 was in closure state, extension spring 7 was in free state, and extension spring 7 this moment does not play a role; Referring to Fig. 2, in the process of opening upper cover 2, when upper cover 2 is not also opened fully, when namely extension spring 7 also is in the left side of rotation center line 9, extension spring 7 handlebar upper covers 2 pull down and make the trend of upper cover 2 closures, in case when upper cover 2 is opened to certain angle, when extension spring is in the right of above-mentioned rotation center line 9, the effect of extension spring 7 will impel upper cover 2 to remain on open mode, and upper cover 2 just can not be at auto-closing under action of gravitation.Need to prove, by means of handle 6, operating personnel's this upper cover 2 that turns clockwise can make upper cover 2 be converted to complete open configuration from closure state, otherwise operating personnel are rotated counterclockwise this upper cover 2 can make upper cover 2 be converted to closure state from complete open configuration.
Compared with prior art, printer of the present utility model, by setting up extension spring 7 and the two ends 71,72 of extension spring 7 being connected with chassis body 1 and upper cover 2 respectively, can effectively shorten the length dimension that printer need to take, thereby reduce the installing space that printer need to take.
Above, be only the preferred embodiment of the utility model, be intended to further illustrate the utility model, but not it is limited.All simple replacements of carrying out according to above-mentioned word and the disclosed content of accompanying drawing are all at the row of the rights protection scope of this patent.
