Under the action of the elastic member 30, the cover-opening buckle 20 tends to move toward the opening of the mounting groove 11; a limiting structure 40 is also provided between the inner bracket 10 and the cover-opening buckle 20 to prevent the cover-opening buckle 20 from popping out of the mounting groove 11 under the action of the elastic member 30. The push-type cover opening mechanism of the present invention is configured by providing a mounting groove 11 on the inner bracket 10 of the box body, and the cover opening buckle 20 and the elastic member 30 can be directly installed in the mounting groove 11. The elastic member 30 provides elastic force to the cover opening buckle 20 and is limited by the limiting structure 40, so that the cover opening buckle 20 can be installed conveniently and quickly.

[0040] Please refer to the following for details: Figure 7 The cover opening mechanism is used to lock or open the upper cover / upper cover assembly 50. One side of the upper cover / upper cover assembly 50 is rotatably connected to the inner bracket 10, and the other side is provided with a hook 51. The hook 51 can enter the installation groove 11 through the through hole 12. The cover opening buckle 20 is provided with a first slot 21 that can hook the hook 51. For details, please refer to Figure 3 、 4The upper end surface of the cover opening buckle 20 is provided with a first recess 25. Only one side wall of the four side walls of the first recess 25 is communicated with the outer side wall of the cover opening buckle 20 and forms an opening. The inner side of the first recess 25 away from the opening is provided with a protruding part 26, which faces the opening. The protruding part 26 is below the first recess 25 and forms a first clamping groove 21 for hooking the clamping hook 51. The upper side of the protruding part 26 is provided with a first inclined surface 261 or a first chamfer to facilitate the cooperation between the second inclined surface 511 or the second chamfer on the clamping hook 51 and the first inclined surface 261 / first chamfer when the upper cover / upper cover assembly 50 is closed, that is, to push the cover opening buckle 20 to further move into the mounting groove 11 and further compress the elastic member 30. When the second inclined surface 511 passes over the first inclined surface 261 after reaching a certain position, the cover opening buckle 20 is reset under the action of the elastic member 30, the first clamping groove 21 hooks the clamping hook 51, and the buckling is achieved.

[0041] Specifically, please refer to 2, 3, the limiting structure 40 includes a limiting groove 13 provided on the inner side wall of the mounting groove 11, and a clamping buckle 22 provided on both sides of the cover opening buckle 20 and matched with the limiting groove 13. The clamping buckle 22 includes a first supporting arm 221 provided on the side wall of the cover opening buckle 20, and a buckling part 222 provided at the end of the first supporting arm 221 and outward. The cover opening buckle 20 is provided with an avoiding position 24 on both sides, and the clamping buckle 22 is located in the avoiding position 24. The cover opening buckle 20 is made of plastic material and is injection molded, so that the first supporting arm 221 has a certain elasticity, and a third inclined surface / third chamfer is provided on the outer side of the buckling part 222, which facilitates the buckling of the clamping buckle 22 into the limiting groove 13, so that the cover opening buckle 20 is limited in the mounting groove 11 under the action of the limiting structure 40, and is elastically outward under the action of the elastic member 30, so that the clamping hook 51 hooks the first clamping groove 21, and the upper cover / upper cover assembly 50 is covered on the inner support 10. The cover opening buckle 20 is pressed manually, the elastic member 30 is further compressed, and the cover opening buckle 20 moves further into the mounting groove 11, so that the clamping hook 51 is separated from the first clamping groove 21, and the upper cover / upper cover assembly 50 can be opened.

[0042] Specifically, please refer to 3, the cover opening buckle 20 is further provided with a positioning groove 23 for embedding one end of the elastic member 30. Specifically, the positioning groove 23 is located on the back surface of the cover opening buckle 20, one end of the elastic member 30 is embedded in the positioning groove 23, and the other end abuts against the inner side wall of the mounting groove 11.

[0043] Specifically, please refer to 5, 6, 8, 9, the inner support 10 outer side is also provided with an outer shell 70, the inner side of the outer shell 70 is provided with a button 60 for pressing the cover buckle 20; The outer shell 70 is provided with a first through hole 71 for embedding the button 60, the button 60 comprises a pressing portion 61 embedded in the first through hole 71, a first limiting portion 62 provided on the outer edge of the pressing portion 61 and located inside the outer shell 70, and a second supporting arm 63 provided on both sides of the first limiting portion 62 and located inside the outer shell 70. The first limiting portion 62 is annular and located at the outer edge of the pressing portion 61, which prevents the button 60 from falling out of the outer shell 70. The inner side of the outer shell 70 is also provided with a first supporting step 72 for supporting the second supporting arm 63, and the first supporting step 72 is provided with a second groove 721 for embedding the second supporting arm 63.

[0044] Specifically, please refer to 2, the bottom or / and both sides of the installation groove 11 are provided with a supporting strip 14, that is, one or two supporting strips 14 can be provided on the bottom of the installation groove 11, or one supporting strip 14 can be provided on each side of the installation groove 11, or one or two supporting strips 14 can be provided on the bottom and one supporting strip 14 can be provided on each side. By providing a plurality of supporting strips 14, the contact area between the cover buckle 20 and the inner side or / and the bottom of the installation groove 11 is reduced, the friction is reduced, and the movement of the cover buckle 20 is more smooth. The long side of the supporting strip 14 is parallel to the moving direction of the cover buckle 20, and is directly integrally injection molded during the forming process of the cover buckle 20.

[0045] The installation mode of the pressing type cover opening mechanism is as follows:

[0046] First, the elastic member 30 is embedded in the positioning groove 23, then the cover buckle 20 with spring is aligned with the installation groove 11, and is directly pressed in. During the pressing process, the two buckles 22 are inwardly retracted, and the buckle 22 is buckled into the limiting groove 13. The limiting groove 13 has sufficient excess for the cover buckle 20 to move in the installation groove 11. Due to the cooperation of the buckle 22 and the limiting groove 13, the cover buckle 20 cannot be separated from the installation groove 11. The pressing portion 61 of the button 60 is embedded in the first through hole 71, and the second supporting arm 63 is embedded in the second groove 721. The inner support 10 is installed into the outer shell 70. At this time, the button 60 corresponds to the cover buckle 20, and pressing the button 60 can make the cover buckle 20 move in the installation groove 11. After releasing, the cover buckle 20 is reset under the action of the spring.

[0047] The utility model also provides a kind of portable printer, which adopts the structure of the pressing type cover opening mechanism.

[0048] To sum up, the push-type cover opening mechanism of the present invention is realized by setting a mounting groove on the inner bracket of the box body, and the cover opening buckle and the elastic part can be directly installed in the mounting groove. The elastic part provides elastic force to the cover opening buckle and is limited by the limiting structure to facilitate the convenient and quick installation of the cover opening buckle.

[0049] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
