The utility model also discloses a portable printer. Under the state that the upper cover subassembly overturns to the maximum angle relative to the base, protruding grain then is spacing in the constant head tank to make the upper cover subassembly obtain the location, can not overturn easily and get off.

Description

Uncap locking structure and have portable printer of this structure

Technical Field

The utility model relates to a lid of printer closes the structure, the utility model discloses still relate to a printer.

Background

At present, when a printer on the market is operated for preventing paper replacement and the like during opening a cover, the upper cover can be automatically closed due to gravity, and a torsion spring is added at a hinged position of a printer shell and the upper cover or a support structure is designed to support the upper cover of the printer almost. When the torsion spring is adopted, the torsion spring is matched with a corresponding uncovering button for use, and the impact is large when uncovering is carried out; when the supporting structure is adopted, the structural design is complicated, the fault is easy to occur, and the manufacturing cost is more superior to that of a torsion spring structure.

Therefore, an improved supporting structure is disclosed in the prior art, and the improved supporting structure is shown in the Chinese utility model patent with the patent number of ZL201820664605.4, namely a printer cover opening self-locking mechanism (the publication number of CN 208216315U), and the improved supporting structure adopts the bulges and the round corners on the elastic ribs to realize the supporting, thereby realizing the clamping function, having simple integral structure and being easy to manufacture and produce.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the first technical problem that provides a succinct locking structure that easily makes of structure in addition to foretell technical current situation.

The utility model aims to solve the second technical problem that a portable printer that can automatic support after the upper cover is opened is provided.

The utility model provides a technical scheme that above-mentioned first technical problem adopted does: the utility model provides a locking structure uncaps, includes the base and can locate the upper cover subassembly on the base with overturning, its characterized in that the one end inboard of upper cover subassembly has the bellying, and the both sides shaping of this bellying has curved spout, and the end shaping that is close to the spout has the constant head tank, correspondingly, the base has the depressed part that supplies the bellying to hold, and the both sides of this depressed part shaping respectively have can make a round trip gliding protruding grain in the spout, under the relative base of upper cover subassembly overturns the state at most angle, aforementioned protruding grain is then spacing in the constant head tank.

Preferably, the inner wall of the positioning groove is spherical, and correspondingly, the outer end surface of the convex particle is also spherical.

Preferably, the protruding portion has a shaft hole, and correspondingly, a shaft pin rotatably engaged with the shaft hole is provided in the recessed portion of the base.

Further, the side wall of the protruding part is recessed to form a shaft part, and the shaft hole is formed in the axial direction of the shaft part.

The utility model provides a technical scheme that above-mentioned second technical problem adopted is: a rubber roll is arranged on a base, a thermal printing head is arranged on an upper cover component, and the rubber roll and the thermal printing head are close to each other and have a gap for printing paper to pass through when the upper cover component covers the base.

Compared with the prior art, the utility model has the advantages of: the convex particles move and guide in the sliding groove, and when the upper cover assembly is turned to the maximum angle relative to the base, the convex particles leave the sliding groove and are limited in the positioning groove, so that the upper cover assembly is positioned and cannot be turned easily. The whole structure is simple, and the manufacture and the production are easy.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1, 2 and 3, the portable printer in this embodiment includes a base 2 and an upper cover assembly 1 that can be turned over on the base 2, a rubber roller 3 is disposed on the base 2, a thermal print head 4 is disposed on the upper cover assembly 1, and when the upper cover assembly 1 is covered on the base 2, the rubber roller 3 and the thermal print head 4 are close to each other and have a gap through which printing paper passes.

When printing, the printing paper enters from the paper inlet 1a, and after printing, comes out from the paper outlet and is cut by the saw teeth 5 on the paper outlet.

The inner side of one end of the upper cover assembly 1 is provided with a convex part 12, two sides of the convex part 12 are formed with arc-shaped sliding grooves 13, the end close to the sliding groove 13 is formed with a positioning groove 14, correspondingly, the base 2 is provided with a concave part 21 for accommodating the convex part 12, and two sides of the concave part 21 are respectively formed with convex particles 23 capable of sliding back and forth in the sliding groove 13.

Referring to fig. 4, when the cover assembly 1 and the base are close to 90 °, that is, when the cover assembly 1 is turned to the maximum angle relative to the base 2, the protruding particles 23 leave the sliding slot 13 and are retained in the retaining groove 14. Therefore, the upper cover assembly is positioned and cannot be turned over easily, and the protruding part and the protruding particles are made of plastic materials and have certain deformation capacity. The boss 12 in this embodiment is formed on the lining member 11 of the lid assembly 1.

The inner wall of the positioning groove 14 is spherical, and correspondingly, the outer end surface of the convex particle 23 is also spherical. As shown in fig. 5, the protrusion 12 has a shaft hole 17, and correspondingly, the recess of the base 2 has a shaft pin 22 rotatably engaged with the shaft hole 17. The side wall of the boss 12 is recessed to form a shaft portion 16, and a shaft hole 17 is formed in the axial direction of the shaft portion 16.
