In the description of the present invention, if an orientation description is referred to, for example, the directions or positional relationships indicated by "upper", "lower", "front", "rear", "left", "right", etc. are based on the directions or positional relationships shown in the drawings, only for convenience of description and simplification of description, and it is not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. When a feature is referred to as being "disposed," "secured," or "connected" to another feature, it can be directly disposed, secured, or connected to the other feature or be indirectly disposed, secured, or connected to the other feature.

In the description of the present invention, if "a plurality" is referred to, it means one or more, if "a plurality" is referred to, it means two or more, if "more than", "less than" or "more than" is referred to, it is understood that the number is not included, and if "more than", "less than" or "within" is referred to, it is understood that the number is included. If reference is made to "first" or "second", this should be understood to distinguish between features and not to indicate or imply relative importance or to implicitly indicate the number of indicated features or to implicitly indicate the precedence of the indicated features.

In addition, unless defined otherwise, technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1, there is shown an overall schematic diagram of a printer according to an embodiment of the present invention, the printer is composed of a main body 2 and an upper cover 1, the upper cover 1 is opened to perform operations such as replacing paper or parts of the main body, and the function of the outer shell is described here with the upper cover 1 as one of the outer shells.

Referring to fig. 2, which is an overall view illustrating an opened state of the printer according to an embodiment of the present invention, the upper cover 1 is opened with respect to the main body 2, and the upper cover 1 is fixed to the main body 2 by a hinge so that the upper cover 1 can rotate with respect to the main body 2.

Referring to fig. 3, fig. 3 is an enlarged view of a region a in fig. 2, a side of the upper case 1 near the hinge protrudes toward the main body to form a protrusion 11, and a side of the main body near the hinge protrudes toward the upper case 1 to form a stopper 21. The stopper 21 restricts the upper case 1 from being opened to an excessive angle.

Referring to fig. 4, fig. 4 is a plan view of an opened state of the printer according to an embodiment of the present invention. At this time, the upper case 1 is opened, and the upper case 1 is rotated with respect to the main body 2.

Referring to fig. 5, fig. 5 is a cross-sectional view taken along the direction B-B in fig. 4, the positions of the bump 11 and the stopper 21 are shown, the stopper 21 is a rectangular stopper, the bump 11 rotates around the hinge following the upper case 1, the surface of the bump 11 has a stopping point 12, and the distance from the stopping point 12 to the rotation center of the bump 11 is greater than the minimum distance from the stopper 21 to the rotation center of the bump 11, so that when the stopping point 12 rotates to the position of the stopper 21, the bump 11 abuts against the stopper 21, and the upper case 1 stops rotating. Therefore, the opening angle of the whole printer is limited, and the upper shell 1 is prevented from being clamped into the gap of the main body 2 or damaged when the opening angle is too large.

In another embodiment of the present invention, the two ends of the rotation shaft of the upper housing are both provided with a bump, and the corresponding stopper is correspondingly disposed on the main body.

In another embodiment of the present invention, the protrusion is also disposed on the lower case, and the corresponding stopper is disposed on one side of the main body close to the lower case.

In another embodiment of the present invention, the stopper is easily impacted due to the long-term opening and closing of the upper case, and the stopper is covered with a layer of buffer material, and rubber is selected as the main material.

Further, in order to avoid impact, an elastic piece such as a spring assembly is additionally arranged at the blocking point, the spring assembly is arranged towards the direction of the stop block, and when the blocking point moves towards the stop block, the spring assembly contacts the stop block to convert the original impact into gradually increased spring force.

While the preferred embodiments of the present invention have been described in detail, the present invention is not limited to the embodiments, and those skilled in the art can make various equivalent modifications and substitutions without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
