The above embodiments are only preferred embodiments of the present invention, and in practical use, the arrangement of the connecting slots and the design of the connecting channels may be varied, and the present invention mainly realizes the non-interference opening of the cover body according to the dislocation of the cover body and the base body between two different hinge positions. And the different clamping structures between the cover body and the base in the embodiment can also be adapted to the moving mode and the opening mode of various cover bodies. Such variations are within the scope of the invention.
It is from top to bottom visible, remove the lid through vertical direction when uncapping, make lid and base form vertical dislocation then, avoid the lid to interfere with the base when rotating to it is smooth to guarantee that the lid opens, and the lid closes the accurate cooperation of the rubber roll on the last temperature sensing piece of lid and the base, guarantees to print the quality. When the lid dislocation was removed, can carry out the dislocation removal along the mode of vertical direction, pitch arc, realize then that block portion breaks away from each other, the lid is opened. Through outer wall clearance fit behind first back outer wall and the second to can guarantee the integrality and the roughness of shell, thereby improve miniature thermal printer's use greatly and feel. Through the cooperation of articulated post and cell body to guarantee lid and pedestal connection stability, it is spacing to utilize width and the poor realization corresponding position of internal diameter promptly, improves the smoothness nature when uncapping and the position accuracy nature when closing the lid.
In addition, through rotatable latch hook for the lid is opening when driving the pothook and rotate, and two pivoted pothooks each other and latch hook can realize rotating the unblock, then open the lid smoothly, and pivoted latch hook simple structure and space occupy for a short time, and the structural layout of uncapping of easily miniature thermal printer is convenient for miniature thermal printer's miniaturization. Stretch into draw-in groove and latch hook cooperation through the pothook, realize then that the stable lid of lid closes to be connected to the elasticity joint of cooperation elastic component and the circumference of spacing portion are spacing, thereby make the lid open and shut stably. Through the spacing cooperation of first location portion and second location portion, locating hole and reference column promptly to it is stable to make lid and base position cooperation, thereby guarantees the relative position of temperature sensing piece and rubber roll, improves and prints the quality.
Moreover, remove the lid through the horizontal direction when uncapping, make lid and base form horizontal dislocation then, avoid the lid to interfere with the base when rotating to open then, guarantee that the lid opens smoothly, and the lid closes the accurate cooperation of the rubber roll on the last temperature sensing piece of lid and the base, guarantee to print the quality. The positions of the cover body and the base are locked by the elastic piece, so that the locking stability is improved, and the printing quality is stabilized. The clamping hook can move in the clamping groove along the horizontal direction and is clamped with the clamping groove, so that the cover body can transversely move within a reasonable stroke range, and the cover opening and closing locking can be realized. Through the cooperation of articulated post and cell body to guarantee lid and pedestal connection stability, it is spacing to utilize width and the poor realization corresponding position of internal diameter promptly, improves the smoothness nature when uncapping and the position accuracy nature when closing the lid.
Finally, remove the lid through the incline direction when uncapping, make lid and base form vertical and horizontal dislocation then, avoid the lid to interfere with the base when rotating to open then, guarantee that the lid opens smoothly, and the lid closes the accurate cooperation of the rubber roll on the last temperature sensing piece of lid and the base, guarantee to print the quality. When the lid dislocation was removed, can carry out the dislocation removal along the mode of incline direction, pitch arc, realize then that block portion breaks away from each other, the lid is opened. Through outer wall clearance fit behind first back outer wall and the second to can guarantee the integrality and the roughness of shell, thereby improve miniature thermal printer's use greatly and feel. The clamping hook can move in the clamping groove along the horizontal direction, is clamped with the clamping groove and is matched with the guide of the inclined guide groove wall, so that the cover body can move in the inclined movement stroke range, and the inclined upper cover opening and the inclined lower cover closing locking are realized.
