Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined to clearly and completely describe the technical solutions of the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention.

Referring to fig. 1 to 2, the present embodiment provides a printer convenient to disassemble and assemble, which includes a printer body 1 having a paper compartment S and an opening and closing cover 2; the opening and closing cover 2 is mounted on the printer body through a hinge device 3 to open and close the paper compartment S through a hinge motion, wherein the range of the hinge motion is 0 to 75 °. The hinge device 3 includes: a rotating shaft 4 and a limiting piece 5. The rotating shaft 4 is a rotating shaft capable of elastically deforming when stressed along the radial direction. The spindle 4 has a first spindle portion 4A and a second spindle portion 4B; the first rotating shaft part 4A passes through a first channel 1A arranged on the printer body 1 and a second channel 2A arranged on the opening and closing cover 2 and can move along the axial direction to be separated from the first channel 1A and the second channel 2A; the second shaft portion 4B has a radial dimension smaller than that of the first shaft portion to form an annular groove provided in the circumferential direction; the limiting piece 5 is arranged on the opening and closing cover 2 and is provided with an embedding part 5A embedded into the annular groove; the fitting portion 5A is slidable from the annular groove to the surface of the first spindle portion 4A when the first spindle portion 4A is axially movable. The rotating shaft is provided with a second rotating shaft part 4B and two first rotating shaft parts 4A which are positioned at two sides of the second rotating shaft part 4B along the axial direction; the printer body 1 is provided with two first channels 1A, and the opening and closing cover 2 is provided with two second channels 2A; each first shaft portion 4A passes through a first passage 1A and a second passage 2A. Further, a second rotating shaft portion 4B is provided at a central position of the rotating shaft 4. If need dismantle the printer that this embodiment provided open and shut lid 2, only need promote pivot 4 along axial displacement, at this moment, pivot 4 will produce elastic deformation along radial, and then pivot 4 atress can break away from first passageway 1A and second passageway 2A completely, can realize printer body 1 and the separation of opening and shutting lid 2 afterwards. If need install printer body 1 again with the lid 2 that opens and shuts, first open and shut lid 2 and insert printer body 1 and make first passageway 1A and second passageway 2A align at the horizontal direction, then stretch into pivot 4 from first passageway 1A in order to pass first passageway 1A and second passageway 2A, in the in-process that pushes pivot 4, the one end of pivot 4 will contact embedding portion 5A earlier, pivot 4 takes place elastic deformation so that pivot 4 can continue to promote along the axial, because the radial dimension of second pivot portion 4B is less than first pivot portion 4A, so when second pivot portion 4B arrived the position corresponding with embedding portion 5A under the drive of pivot 4, pivot 4 will take place elastic recovery, in the annular groove that second pivot portion 4A forms on its surface, the installation of the lid 2 that opens and shuts has both been accomplished. In this embodiment, the rotating shaft 4 further has a portion with an annular groove, and the rotating shaft is matched with the embedded portion 5A of the limiting member 5, so that the axial stress cannot overcome the friction force generated between the embedded portion 5A and the annular groove, and therefore, when the opening and closing cover 2 is hinged to the printer, the rotating shaft 4 cannot move axially, and the opening and closing cover is stably and reliably connected in the working process. Under the condition that the rotating shaft cannot be elastically deformed along the radial direction, when the rotating shaft is disassembled and assembled, the rotating shaft is in interference fit with the wall parts and the embedded parts of the two channels, and although the rotating shaft can also meet the requirement that the rotating shaft moves along the axial direction, a user needs to apply a larger acting force, and the rotating shaft can be controlled to move along the axial direction by the user through the elastic deformation of the rotating shaft along the radial direction.

Further, as shown in fig. 1 to fig. 2, in this embodiment, the groove wall surfaces on both sides of the annular groove are respectively inclined outward gradually in the axial direction, and the surfaces of the embedding portion 5A, which are matched with the groove wall surfaces, are inclined surfaces. In other embodiments of the present invention, the surface of the embedded portion 5A matching the surface of the groove wall may be a curved surface.

The above is the first embodiment of the present application, but it is easy to understand that, under the inventive concept of the present application, the present application is not limited to the above embodiments, and in another embodiment, the embedded portion may be an embedded portion capable of elastically deforming when being stressed; in another embodiment, the inner walls of the first and second channels are capable of elastic deformation when subjected to a force. Based on the above description, those skilled in the art will understand that, in order to enable the rotating shaft to slide along the axial direction better, any one of the rotating shaft, the embedded portion or the inner wall of the channel may have a certain elastic bending property, and may be made of an elastic rubber material, for example.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
