It will be appreciated that the above definitions are merely to facilitate understanding of the relative positional relationship of the various components in the printer and should not be construed as limiting the utility model.

As shown in fig. 1 and 4, in an embodiment, a printer is provided, which can be used for printing labels, express sheets, and other papers. The printer may include a cover assembly 200, a base assembly 300, and a cover opening structure for the printer (hereinafter referred to as a cover opening structure 100). The door opening structure 100 may be used to effect opening and closing between the cover plate assembly 200 and the base assembly 300 in a printer. In an embodiment, one side of the cover assembly 200 may be hingedly connected to one side of the base assembly 300.

Referring to fig. 5, fig. 7, and fig. 8, the cover opening structure 100 may include an elastic member 130, at least one buckle 110, and at least one first fastening portion 120. The first fastening portion 120 may be formed on the cover assembly 200. Specifically, the first fastening portion 120 may be located at a side of the cover assembly 200 that is hinged to the base assembly 300 away from itself. The buckle 110 may include a second fastening part 111, a hinge part 112, and a driving part 113, which are sequentially disposed. And the second fastening part 111, the hinge part 112 and the driving part 113 may be an integral structure.

The hinge 112 may be hinged with the base assembly 300. And the junction of the hinge 112 and the base assembly 300 may be located on a side of the base assembly 300 away from the hinge itself with the cover assembly 200. Accordingly, the clasp 110 may rotate relative to the base assembly 300. In addition, the driving portion 113 may include a first end 11301 and a second end 11302, and the second end 11302 may be disposed proximate to the hinge portion 112.

In an embodiment, the distance between the first end 11301 of the driving portion 113 and the hinge portion 112 may be greater than the distance between the second fastening portion 111 and the hinge portion 112. The elastic member 130 can act on the first end 11301 of the driving portion 113 to drive the second fastening portion 111 to be fastened with the first fastening portion 120.

When the cover assembly 200 and the base assembly 300 are in the closed state, the distance between the first end 11301 of the driving portion 113 and the hinge portion 112 is greater than the distance between the second fastening portion 111 and the hinge portion 112. The buckle 110 may form a labor-saving lever structure with respect to the elastic member 130. The elastic member 130 can drive the second fastening portion 111 to be fastened with the first fastening portion 120 only by applying a small force to the driving portion 113. When the cover assembly 200 and the base assembly 300 need to be opened, only a small force is applied to the driving part 113 to overcome the force of the elastic member 130, so that the cover assembly 200 and the base assembly 300 can be opened.

Thus, the elastic force of the elastic member 130 may be set to be relatively small, i.e., the interaction force between the elastic member 130 and the buckle 110 may also be relatively small. On the one hand, in an extreme transportation environment, the possibility that the elastic member 130 acts on the structure such as the buckle 110 to cause deformation and damage of the corresponding structure can be reduced. On the other hand, the durability of the lid opening structure 100 can be increased, and the service life can be prolonged.

As shown in fig. 1, further, the cover assembly 200 may include a cover 210 and a second bracket 220. The cover 210 may be fixedly connected to a side of the second bracket 220 away from the base assembly 300 by a screw connection, a clamping connection, or an adhesive connection.

The first fastening part 120 may be a latch structure formed on the second bracket 220, and one side surface of the latch structure may be used as one side wall of the insertion hole 221. When the second fastening portion 111 is fastened to the first fastening portion 120, the second fastening portion 111 can be inserted into the insertion hole 221 and fastened to a side of the first fastening portion 120 near the cover 210. In addition, when the second fastening portion 111 is separated from the first fastening portion 120, the second fastening portion 111 can move in the insertion hole 221 and can be separated from the insertion hole 221.

As shown in fig. 1 and 4, the base assembly 300 may include a bottom chassis 310 and a first bracket 320. The bottom case 310 may be fixedly connected to a side of the second bracket 220 away from the cover assembly 200 by screw connection, adhesion, or clamping.

In addition, a supporting plate 322 is also protruded from a side of the first bracket 320 near the bottom case 310, and can be used as a mounting carrier for other structural members in the printer, for example, a gear set connected to a rubber roller in a driving manner.

In an embodiment, the support plate 322 may divide the assembly chamber 330 into different spaces, and the connection frame 160 and the driving part 113 may be disposed at both sides of the support plate 322. In an embodiment, the first end 11301 of the driving part 113 may be extended with a connection arm 1131 parallel to the length direction of the printer. The connecting arm 1131 may be disposed through the supporting plate 322, so as to extend to the space where the connecting frame 160 is located, and be fixedly connected to the connecting frame 160.

Correspondingly, the support plate 322 may be provided with a guide groove 3221 through which the connecting arm 1131 passes, where the dimension of the guide groove 3221 in the swinging direction of the driving portion 113 may be greater than or equal to the swinging amplitude of the driving portion 113, so as to avoid interference to the movement of the driving portion 113.

As shown in fig. 1 to 3, the second fastening portion 111 may protrude from a side of the first bracket 320 away from the bottom case 310 so as to be fastened to the first fastening portion 120. In an embodiment, the first bracket 320 may be provided with a via hole 323 in communication with the assembly portion 321, and the second fastening portion 111 may be disposed through the via hole 323 and protrude from a side of the first bracket 320 away from the bottom case 310. In addition, the dimension of the via hole 323 in the swinging direction of the second fastening portion 111 may be greater than or equal to the swinging amplitude of the second fastening portion 111, so as to avoid interference with the movement of the second fastening portion 111.

In other embodiments, the lid opening structure 100 may also include a latch 110, where the latch 110 is rotatably mounted to the first bracket 320. And in the direction parallel to the length direction of the printer, the buckle 110 is disposed near the middle of the first bracket 320, and correspondingly, the first buckling part 120 may also be formed at the middle of the second bracket 220.

Of course, in other embodiments, the lid opening structure 100 may also include three, four, or six equal numbers of snaps 110. The plurality of buckles 110 may be connected to the connection frame 160.

In an embodiment, the mounting base 150 may be fixedly connected to a side of the first bracket 320 near the bottom shell 310 by a screw connection, an adhesive connection or a clamping connection, and the mounting base 150 may be disposed opposite to a side of the connecting frame 160 near the fastening side 1111.

In some embodiments, the elastic member 130 may be a spring. One end of the elastic member 130 may abut against a side of the connecting frame 160 near the mounting base 150. The other end of the elastic member 130 may abut against the mounting seat 150. When the connecting frame 160 is not acted by external force, the elastic member 130 can be in a natural extension state or a compression state.

In other embodiments, the elastic member 130 may be a flexible column or a spring.

In some embodiments, a limiting groove 151 is further formed on a side of the mounting base 150 near the connecting frame 160, and an end of the elastic member 130 near the mounting base 150 can be assembled in the limiting groove 151. In one aspect, assembly of the elastic member 130 may be achieved, preventing the elastic member 130 from being separated from the mounting base 150 and the connection frame 160. On the other hand, the probability of the problem of the elastic member 130 tilting can be reduced, and the elastic member 130 can provide stable and reliable elastic force for the connecting frame 160.

In other embodiments, one end of the elastic member 130 may be fixedly connected to a side of the connecting frame 160 away from the fastening side 1111 of the second fastening portion 111. The other end of the elastic member 130 may be fixedly coupled to the first bracket 320. When the connecting frame 160 is not acted by external force, the elastic member 130 may be in a stretched state or a natural stretched state.

In the embodiment, the elastic member 130 and the mounting seat 150 are disposed between the two support plates 322 on the first support 320, and the positions of the elastic member 130 and the mounting seat 150 can be arbitrarily adjusted between the two support plates 322 according to the requirement, and the positions are not limited by a gear set or the like, and the whole volume of the printer is not increased, which is beneficial to realizing the miniaturization design of the printer.
