Referring to fig. 1 and 2, the push type door opening mechanism of the present disclosure is used for separation between a housing 10 and a housing 20, and the housing 10 and the housing 20 are rotatably connected by, for example, a rotation shaft 30.

The push-type door opening mechanism comprises a locking assembly 31, a pressing assembly 32 and a force transmission assembly 33, the locking assembly 31 comprising a cantilever member 8 and a hook lock (not shown in the figures) for unlocking the housing 10 and the housing 20 and arranged to unlock the housing 10 and the housing 20 when the cantilever member is rotated to the first position. Preferably, the locking assembly 31 further comprises a rotation shaft and a third restoring member for automatically restoring the position of the cantilever member 8 to the first position when the cantilever member 8 is rotated to the first position.

The pressing assembly 32 comprises a button 5 and a first reset member 6, wherein the button 5 can be arranged on the shell 10 in a pressed manner, and comprises a pressing surface arranged on the surface of the shell 10, so that the pressing is convenient. The first reset member 6 is used for resetting the button position.

The force transfer assembly 33 includes a force-receiving end and a drive end. The drive end is held in relatively fixed connection with the cantilever member 8 to drive the cantilever member to move. The stress end is used for receiving the stress of the button 5, for example, the button 5 generates displacement after being pressed, so as to drive the second end to move, and further drive the cantilever part 8 to rotate to the first position to unlock the shell and the seat body.

In some embodiments of the force transfer assembly 33, the force transfer assembly 33 includes a first adapter 9 and a second adapter 3 rotatably disposed within the housing, the first adapter 9 including a first end 901 and a second end 902, and the second adapter 3 including a first end 301 and a second end 302. The first adapter 9 is arranged inside the housing by a first pin 11, and the second adapter 3 is arranged inside the housing by a second pin 14. At this time, the force receiving end is the second end 902 of the first adapter 9, and the driving end is the first end 301. (it is necessary to provide a schematic view of the parts of the snap-engagement cantilever beam 8 integral with the second rotating member 3, now appearing as separate in cross-section.)

The first end 301 of the second adapter 3 is connected to the cantilever member 8, such as by a connecting member fixedly, or both are engaged with each other. As with the snap-in embodiment shown with reference to fig. 2, one of the cantilever member 8 and the first end 301 of the second adapter member 3 provides a recess, and the other provides a protrusion that mates with the recess to effect securement.

The second end 302 of the second adapter 3 is in point contact, or surface contact, or with a gap arrangement with the first end 901 of the first adapter 9. Preferably, the transmission of the rotational force is achieved by a point contact or a surface contact, as in the embodiment shown in fig. 2, the first end 901 of the first adapter 9 is provided with a bump, which is in point engagement with the second end 302 of the second adapter 3.

The first end 301 and the second end 302 of the second adapter 3 are arranged on different height planes, as shown in figure 2 in a reverse-turn type bending configuration, limited by the position of the cantilever member 8. The second adapter 3 comprises two high flat surfaces, the lower high flat surface serving as a first end 301 for engaging the cantilever member 8 and the lower flat surface serving as a second end 302 for mating with the first adapter 9. It will be appreciated by those skilled in the art that the shape of the second adapter 3 and the first adapter 9 is designed according to the specific positions of the cantilever member 8 and the push button 5, and is not limited to the structure shown in the drawings.

In some embodiments, the force transfer assembly further comprises a second return member 4 for return of the second adapter member 3. In the embodiment shown in fig. 2, the second restoring member 4 is an elastic member disposed between the inner wall surface of the seat body 20 and the other end 302 of the second adapter member 3, and when the other end 302 is not forced by the first adapter member 9, the position of the second adapter member 3 is driven to restore, and the position of the cantilever member 8 is further restored from the first position.

In some embodiments, the first restoring member 6 is an elastic member with an elastic deformation direction consistent with the pressing direction of the button, and after the button 5 does not receive the external pressing force, the elastic member forces the button 5 to restore to the original position by virtue of its own elastic force. On the basis of the above embodiment, the pressing assembly 32 further includes a platform 16 disposed below the button, and both ends of the first elastic member respectively abut against the platform 16 and the button 5 body. Preferably, the button 5 further comprises a protruding cylinder 15, the platform 16 provides a recess, the upper end of the elastic member is sleeved on the periphery of the protruding cylinder 15, and the lower end is accommodated in the recess of the platform 16.

To achieve a force transfer upon depression of the push button 5, in some embodiments the push button 5 further comprises a projecting arm 7 passing through the platform 16 and being displaced together with the push button for transferring the pressing force of the push button towards the first end of the force transfer assembly for driving the force-receiving end of the force transfer assembly 33, i.e. the second end 902 of the first adapter 9 in fig. 2, into displacement. The projecting arms 7 and the second end 902 may be in point contact or in surface contact or in a gap arrangement. The position, shape and number of the projecting arms 7 are not limited to the embodiment shown in fig. 2.

The opening process of the housing 10 is understood with reference to fig. 2, in that the operator pushes the button 5 downwards, the button 5 transmits a downward pressure to the second end 902 of the first adapter 9 by means of the protruding arm 7, forcing the second end 902 of the first adapter 9 to rotate downwards, while the button presses the first reset member 6.

After the second end 902 of the first adaptor 9 rotates downward, the first end 901 of the first adaptor 9 rotates upward under the support of the first pin 11, so as to push the second end 302 of the second adaptor 3 to rotate upward, and at this time, the second end 302 of the second adaptor 3 presses the second reset element 4 at the same time.

The second adaptor 3 is supported by the second pin 14, and the first end 301 rotates downward and engages the cantilever 8, so that the cantilever 8 'rotates downward to the position where the cantilever 8' is located, which is the first position of the latch opening housing. At this time, the hook lock is opened, and the housing 10 is automatically opened in the a direction.

After the shell 10 is opened, the button 5 is not pressed down, and then returns to the original position upwards under the drive of the first reset piece 6, and the first transfer piece 9 is not forced any more and returns to the horizontal position. The second adapting piece 3 reversely rotates under the drive of the second resetting piece 4, returns to the position shown in fig. 2, drives the cantilever piece 8 to leave the first position and returns to the original position.

The button door opening mechanism is simple to use, and the shell is opened simply and laborsaving by means of the lever structures of the first adapter and the second adapter and the elastic structure of the reset piece, so that the handle is lighter and the use is convenient.

The printer comprises a shell, a base, a printing module and a printing rubber roller, and the shell and the base are opened by using the upper pressing type door opening mechanism.
