The printer further includes a lid release button 14, and the lid release button 14 is rotatably engaged on the lid body 13.

It should be noted that, in the present embodiment, the body 12 is a paper bin casing, and the cover 13 is a paper bin upper cover for closing the paper bin opening. However, in other embodiments, the application of the open-close button 14 in this embodiment is not limited to this, and may be disposed in other places where the open-close lid is needed, such as: the body 12 may be an access cabin housing of the printer, the cover 13 is an access cover covering the access cabin housing, and the cover opening button 14 is disposed on the access cover. And the following steps: the body 12 may be a box body of a storage box on a printer, the cover 13 is a box cover covering the box body, and the cover opening button 14 is disposed on the box cover, which is not limited in this embodiment.

Referring to fig. 3, in the present embodiment, the decap button 14 includes: a pressing portion 140 for pressing operation by a user, a clamping portion 141 and an elastic arm 142. The engaging portion 141 is configured to engage with the body 12 to lock the cover 13, and to be separated from the body 12 in response to a pressing operation of a user to release the cover 13 in the locked state. The clamping manner includes, but is not limited to, clamping by a hook, a snap, or other separable clamping manner, and a skilled person may refer to the clamping structure in the prior art, which is not described herein again.

In this embodiment, the elastic arm 142 abuts on the cover 13 and applies a force to the fastening portion 141 in a direction toward the direction of maintaining the fastening, and since the elastic arm 142 can generate elastic deformation, in the locked state, the elastic arm 142 abuts on the cover 13, so as to generate an elastic force that maintains the fastening of the fastening portion 11 on the body 12 to lock the cover 13, and the elastic force is applied to the lid opening button 14 in a direction toward the direction that maintains the fastening of the fastening portion 141 and the body 12, so that the cover 13 can be stably in the locked state.

In this embodiment, the elastic arm 142, the pressing portion 140 and the engaging portion 141 are integrally formed, so that the number of connecting structures or connecting members in the open cover button 14 can be reduced, and the overall structure of the open cover button 14 is simple and reliable. It should be noted that, in this embodiment, the elastic arm 142, the pressing portion 140 and the fastening portion 141 may be formed by one-step injection molding, so that the three components belong to a common integral component, and at this time, the three components are made of the same material, and in this embodiment, a plastic material is preferred, and the integral injection molding method has a lower cost and a higher application value. In addition, the elastic arm 142, the pressing portion 140 and the fastening portion 141 can also be respectively used as separate members to be fixedly connected to a main body member, that is, the three members are fixedly connected to each other, and at this time, the three members can be made of different materials, and the embodiment is not limited herein.

Referring to fig. 3 to 6, in the present embodiment, the door release button 14 is provided to be rotatable about a set axis, and the catching portion 141 and the elastic arm 142 are provided on both sides of the set axis, respectively. Specifically, the lid release button 14 further includes a body portion 143, the elastic arm 142 is configured to extend from the body portion 143 toward a first side, the latch portion 141 is configured to extend from the body portion 143 toward a second side, wherein the first side and the second side are opposite in direction, and the body portion 143 is rotatably coupled to the lid body 13 via a pivot 15, i.e., the body portion 143 is coupled to the lid body 13 in a lever configuration. When the cover needs to be opened, a user can apply sufficient pressure to the pressing portion 140 along the pressing direction, and the force applied to the pressing portion 140 can be transmitted to the clamping portion 141 through the main body portion 143 of the lever structure, so that the clamping portion 141 moves toward the direction of separating from the body 12.

In this embodiment, the body 12 is provided with a locking portion 121 engaged with the engaging portion 141, and the locking portion 121 is formed by extending an inner vertical wall 123 of the body 12 along a lateral direction. The engaging portion 141 is provided with a slot adapted to engage with the locking portion 121.

In this embodiment, the cover 13 is provided with a supporting portion 131 against which the elastic arm 142 abuts.

In order to more clearly illustrate the cap locking and cap opening principle of the cap opening button 14 in the present embodiment, as shown in fig. 7 to 8, the main body 143 corresponds to a lever with the pivot 15 as a fulcrum, the pressing portion 140 and the elastic arm 142 are located at one moment arm of the lever, and the slot on the engaging portion 141 is located at the other moment arm of the lever. When the cover is closed, the supporting portion 131 generates a counterclockwise pressure F1 on the elastic arm 142, and the slot receives a clockwise pressure, and the pressure can engage the slot with the locking portion 121, that is, lock the cover 13 on the machine body 12. When the cover needs to be opened, the user applies a pressing force F4 to the pressing portion 140 in the pressing direction, i.e. the clockwise direction, and when the vertical component of the force F4 on the first force arm can be greater than the vertical component of the force F1 on the first force arm, the slot moves towards the direction of separating from the locking portion 121 until the two separate from each other to release the cover 13.

In this embodiment, the supporting portion 131 is a protrusion formed on the cover 13 and extending toward the elastic arm 142. However, as some variations of this embodiment, the supporting portion 131 may be detachably fixed on the cover 13, for example, the supporting portion 131 is fixed on the cover 13 by screws, so as to facilitate subsequent maintenance and replacement.

Referring to fig. 3, 7 and 8, the body 12 is provided with a limiting edge 122 adapted to limit the pressing portion 140 from continuing to rotate after the slot is separated from the locking portion 121, and it can be understood that if the pressing portion 140 continues to rotate, the degree of bending deformation of the elastic arm 142 abutting against one side of the supporting portion 131 is increased, the pressure transmitted to the supporting portion 131 is also increased, and in the long term, the service life of the lid release button 14 is reduced.

Example two:

the difference between the first embodiment and the second embodiment is that, referring to fig. 9, the lid opening button 14 is rotatably engaged with the body 12. The lid release button 14 includes: a pressing portion 140 for pressing operation by a user, a clamping portion 141 and an elastic arm 142. The locking portion 141 is configured to be able to be engaged with the cover 13 to lock the cover 13, and to be separated from the cover 13 in response to a pressing operation of a user to release the cover 13 in the locked state. The elastic arm 142 abuts against the body 12 and biases the engaging portion 141 in a direction of maintaining engagement.

In this embodiment, the body 12 is provided with a support portion 131 against which the elastic arm 142 abuts.

In this embodiment, the cover 13 is provided with a locking portion 121 engaged with the fastening portion 141, and the locking portion 121 is formed by extending an inner vertical wall of the cover 13 along a lateral direction.

In addition, in the present embodiment, the decapping button 14 is provided in two sets, and the decapping buttons 14 are symmetrically distributed on the left and right sidewalls of the printer 1, so that the locking of the cover 13 is more reliable.

In summary, in the two embodiments, by the arrangement and the cooperation of the pressing portion 140, the clamping portion 141, the locking portion 12 and the elastic arm 142, the cover 13 can be locked on the corresponding body 12 without using a spring and a plurality of related connecting structures or connecting members, so that the overall structural design of the cover opening button 14 is simpler, and the installation of the cover opening button 14 is firmer and more reliable, thereby reducing the assembly cost and the later maintenance cost.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention.
