[0029] like Figures 1 to 5 As shown, in the present embodiment, the push-to-open cover structure comprises a main body 1 and an upper cover 2, wherein the upper cover 2 is arranged on the main body 1, and a buckle portion 3 which can be snapped onto the main body 1 is arranged on the upper cover 2, and a mounting opening 5 is provided on the main body 1, and an unlocking portion 6 is slidably fitted on the mounting opening 5, and a rocker arm 7 is rotatably connected in the main body 1, and one end of the rocker arm 7 abuts against the buckle portion 3, and the other end abuts against the unlocking portion 6, and the rocker arm 7 pushes the buckle portion 3 to disengage from the main body 1 when the unlocking portion 6 slides.

[0030] When unlocking, the unlocking part 6 is pushed so that the unlocking part 6 slides downward along the mounting opening 5, so that the unlocking part 6 can press down the other end of the rocker arm 7, causing the rocker arm 7 to rotate, and further one end of the rocker arm 7 pushes the buckle part 3 to disengage from the main body 1 to achieve unlocking.

[0031] With respect to the deficiencies of the prior art, in the utility model, the push-to-open lid structure can set the unlocking part 6 on the main body 1 to avoid the force component direction of the unlocking part 6 being consistent with the direction of closing the lid, thereby facilitating opening the lid; moreover, the unlocking part 6 is a side-push type and is located on the main body 1, and the lid is opened by rotating and pushing the buckle part 3 through the rocker rod 7, so that the contact area between the unlocking part 6 and the hand can be made large enough and the occupied volume is small, and the internal corner space of the main body 1 can be fully utilized by the unlocking method of rotating the rocker rod 7, so that the overall structure can be extremely compact, so that the push-to-open lid structure has the advantages of easy lid opening and compact structure.

[0032] In some embodiments, the unlocking portion 6 includes a push button 9, a flat plate 11 and a pressure block 8 connected in sequence, the push button 9 is slidably fitted on the mounting opening 5, one end of the pressure block 8 passes through the flat plate 11 and is connected to the middle part of the inner side of the push button 9, the other end of the swing rod 7 has an extension arm 10, the length direction of the extension arm 10 is perpendicular to the sliding direction of the unlocking portion 6, the bottom of the pressure block 8 abuts against the upper end of the extension arm 10; the length direction of the pressure block 8 is parallel to the sliding direction of the unlocking portion 6. Specifically, by pushing the push button 9, the push button 9 slides downward on the mounting opening 5, at which time the flat plate 11 and the pressure block 8 also move downward together, so that the pressure block 8 can press down the upper end of the extension arm 10, so that the swing rod 7 can rotate to achieve unlocking;

[0033] It should be noted that since the pressure block 8 is connected to the middle part of the inner side of the push button 9, when the push button 9 pushes the extension arm 10 of the rocker arm 7 to rotate through the pressure block 8, the reaction force received is always in the middle part of the push button 9. Even if the extension arm 10 of the rocker arm 7 tilts, the push button 9 will not be subjected to the plane torque and rotate and get stuck, thereby improving the stability of the unlocking part 6 during operation.

[0034] In some embodiments, the swing arm 7 includes a first swing arm 71, a second swing arm 72 and a rotating part 73, the rotating part 73 is rotatably connected to the main body 1 through a rotating shaft, the first swing arm 71 is arranged on the rotating part 73 and abuts against the buckle part, the second swing arm 72 is arranged on the rotating part 73, the extension arm 10 is located at the end of the second swing arm 72, and an elastic reset member is arranged on the rotating shaft; the cross section of the swing arm 7 is J-shaped. Specifically, by setting the first swing arm 71, the second swing arm 72 and the extension arm 10, the internal side space of the main body 1 can be fully utilized, so that the overall structure is compact; in addition, the swing arm 7 is rotated through the rotating shaft, and the swing arm 7 is driven to rotate in the opposite direction through the elastic reset member to reset the unlocking part 6.

[0035] In some embodiments, the buckle portion 3 includes two hooks 12 arranged on the upper cover 2, a hook shaft 13 is transmission-connected between the two hooks 12, at least one of the hooks 12 is provided with an extension arm 15, a compression spring 16 is provided between the extension arm 15 and the upper cover 2, a protrusion 17 is provided on the main body 1, and the lower end of the hook 12 can be snapped onto the protrusion 17; both ends of the hook shaft 13 are provided with flat positions, and the two hooks 12 are respectively connected to the two flat positions. Specifically, the two hooks 12 transmit torque through the hook shaft 13. Only the hook 12 on one side needs to be opened, unlocked and reset, and the hook 12 on the other side is also unlocked and reset synchronously, so that the structure occupies a small space; when the upper cover 2 is closed, the lower end of the hook 12 is clamped on the protrusion 17 to achieve a buckle; when the upper cover 2 needs to be opened, the rocker rod 7 pushes the lower end of the hook 12 to disengage from the protrusion 17 to achieve unlocking; in addition, the compression spring 16 is used to reset the hook 12, and there is no need to use a torsion spring to reset it, so that the structure is simple and the space is more compact.

Specifically, when the cover is closed, the print head 22 abuts against the rubber roller 23; when the buckle portion 3 is unlocked, the upper cover 2 is bounced up by the elastic force of the elastic member 21 to realize the opening of the cover.

[0038] In addition, the utility model also includes a printer, which includes the above-mentioned sliding and pushing cover opening structure. Specifically, the specific structure of the printer refers to the above-mentioned embodiment. Since the printer adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.
