Abstract
The utility model discloses an improved structure for a printing head of a thermal printer. The improved structure comprises a body, a mounting plate and springs, wherein two ends of the mounting plate are inserted into the body in a clearance mode; two ends of the springs are pressed against a spring mounting seat and the mounting plate on the body; more than one open groove is formed on the spring mounting seat; and a limiting rod with a limiting function is arranged in the center of each spring. When the improved structure is assembled, one ends of the springs are sleeved on convex columns of the mounting plate, the other ends of the springs slide into and is pressed against the open grooves on the spring mounting seat from openings of the open grooves on the spring mounting seat, so that the procedure that the commonly used printing head is arranged through screws is eliminated, and the printing head is conveniently and quickly assembled; and a spring fixing method is adopted, so that the problem that the screws drop because the printing head shocks in the long-term using process is solved, and the printing head is firmly and reliably arranged.
Description
Technical field
The utility model relates to a kind of thermal printer, particularly relates to a kind of thermal printer printhead and improves structure.
Background technology
The operation principle of thermal printer is that the semiconductor heating element heater is installed on the printhead, just can print the pattern that needs behind printhead heating and the contact thermal printing paper, and its principle and heat-sensitive type facsimile machine are similar.The printhead of thermal printer is the critical component of thermal printer.The printhead of commonly using mainly is made up of body, installing plate and spring, and spring is fixed on the installing plate through screw.Because this structure need pass through the screw fixing spring, assemble up comparatively complicatedly, and the screw vibrations owing to printhead in long-term use that play position-limiting action come off easily, service life is shorter.
The utility model content
The purpose of the utility model is to provide a kind of thermal printer printhead improvement structure simple, reliable installation of assembling.
For realizing above-mentioned purpose, the technical solution of the utility model is:
The utility model is that a kind of thermal printer printhead improves structure, and it comprises body, installing plate and spring; Described body has a spring mounting seat and two cantilevers, and described two cantilevers vertically stretch out from the two ends of spring mounting seat; The gap between two ends of described installing plate is plugged in the two cantilever slots of body; The two ends of described spring lean between the spring mounting seat and installing plate of body; Offer more than one open slot on the described spring mounting seat, the opening of this open slot is positioned on the sidewall of spring mounting seat; Described spring is provided with the gag lever post of position-limiting action together for the compression spring in the central authorities of spring, and this gag lever post is made up of the extension of spring wire tail end and with the spring center line parallel or overlap.
Described installing plate is provided with the projection that is used to be nested with spring; One end of described spring is socketed on this projection and leans on installing plate, and the other end of spring leans on the open slot of spring mounting seat.
After adopting such scheme; Because during the utility model assembling; One end of spring is socketed on the projection of installing plate; The other end of spring slips into and leans in the open slot of spring mounting seat from the opening of spring mounting seat open slot, has save and has commonly used the operation that the printhead screw is installed, and assembles up very convenient, fast.And this fixed form of the utility model spring does not exist screw because of the vibrations of the printhead problem that comes off in long-term use, installs more firmly, reliable.
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

Fig. 2 is the axonometric drawing of the utility model body;
Fig. 3 is the vertical view of the utility model;
Figure 41 is the front view of the utility model spring;
Figure 42 is the cutaway view of the utility model spring;
Figure 43 is the vertical view of the utility model spring.
The specific embodiment
As shown in Figure 1, the utility model is that a kind of thermal printer printhead improves structure, and it comprises body 1, installing plate 2 and spring 3.
In conjunction with Fig. 2, shown in Figure 3, described body 1 has a spring mounting seat 11 and two cantilevers 12,13, and described two cantilevers 12,13 vertically stretch out from the two ends of spring mounting seat 11.The gap between two ends of described installing plate 2 is plugged in two cantilevers, 12,13 slots of body 1.Offer two open slots 111 on the described spring mounting seat 11, the opening of these two open slots 111 is positioned on the sidewall 112 of spring mounting seat 11, so as when assembling spring 3 can slip into from this opening.
Described installing plate 2 is provided with two projections 21,22 that are used to be nested with spring 3; One end of described spring is socketed on these two projections 21,22 and leans on installing plate 2, and the other end of spring 3 leans on the open slot 111 of spring mounting seat 11, makes the two ends of spring 3 lean between the spring mounting seat 11 and installing plate 2 of body 1.
Like Figure 41, Figure 42, shown in Figure 43, described spring 3 is formed by the spring wire coiling for the compression spring.Central authorities at spring 3 are provided with the gag lever post 31 of position-limiting action together, and this gag lever post 31 is made up of and or coincidence parallel with spring 3 center lines the extension of spring wire tail end.
Like Fig. 1, shown in Figure 3, the assembling process of the utility model:
1, the gap between two ends with installing plate 2 is plugged in two cantilevers, 12,13 slots of body 1;
2, the end with spring 3 is socketed on the projection 21,22 of installing plate 2, and the other end of spring 3 slips into and leans in the open slot 11 of spring mounting seat 11 from the opening of spring mounting seat 11 open slots 111.
The emphasis of the utility model just is: offer open slot on the body spring mounting seat, be provided with the gag lever post of position-limiting action together in the central authorities of spring.
The above; Be merely the utility model preferred embodiment; Open slot quantity can be decided according to the quantity of spring; So can not limit the scope that the utility model is implemented with this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
