[0025] As Figures 1-6As shown, a printer press type cover opening structure, comprising a lower middle frame 100 and an upper middle frame 101, the upper middle frame 101 is hingedly installed above the lower middle frame 100, a rotating shaft 102 is rotatably installed inside the upper middle frame 101, rotating hooks 103 are installed at both ends of the rotating shaft 102 in length direction, elastic pulling mechanisms 200 are arranged at both sides of the inside of the upper middle frame 101, the elastic pulling mechanisms 200 can exert elastic pulling force on the rotating hooks 103. Wedge blocks 104 are installed at both sides of the lower middle frame 100, cover top blocks 105 are limitingly and slidingly installed at both sides of the lower middle frame 100 in horizontal direction, and the cover top blocks 105 are arranged below the wedge blocks 104, a cover opening mechanism 300 is arranged at one side of the lower middle frame 100, the cover opening mechanism 300 can push the cover top blocks 105 to move in the direction of the rotating hooks 103.

[0026] When the upper middle frame 101 is closed, the inclined surface at the bottom of the rotating hook 103 will press the inclined surface of the wedge block 104, so that the rotating hook 103 overcomes the pulling force of the elastic pulling mechanism 200 and opens, so that it can hook below the wedge block 104, achieving the purpose of single-handed cover opening, when it is needed to open the upper middle frame 101, only need to push the cover top blocks 105 to slide in the direction of the rotating hooks 103 by the cover opening mechanism 300, and the rotating hooks 103 are separated from the wedge blocks 104, because the two rotating hooks 103 are connected by the rotating shaft 102, so when one of the rotating hooks 103 is separated from the wedge block 104, the other rotating hook 103 will also be separated from the wedge block 104, achieving the purpose of single-handed cover opening, it is more convenient to use, and improves the user's experience.

[0027] Preferably, the elastic pulling mechanism 200 comprises a fixed rod 201 and a tension spring 203, the fixed rod 201 is installed inside the upper middle frame 101, one end of the tension spring 203 is sleeved on the outer surface of the fixed rod 201, the outer surface of the rotating hook 103 is provided with a hook hole 202, and the other end of the tension spring 203 is hooked in the hook hole 202.

[0028] Because the position of the fixed rod 201 is fixed, the tension spring 203 can exert elastic pulling force on the rotating hook 103, during the closing process of the upper middle frame 101, the rotating hook 103 is pressed by the wedge block 104, driving the rotating hook 103 to rotate, so that the hook hole 202 moves away from the fixed rod 201 and stretches the tension spring 203, when the hook part of the rotating hook 103 moves below the wedge block 104, the rotating hook 103 is reset under the action of the pulling force of the tension spring 203, and is hooked below the wedge block 104, achieving the purpose of fixation.

[0029] Preferably, the cover opening mechanism 300 comprises an operation port 301 formed on the outer surface of the lower middle frame 100, and a cover opening button 302 is rotatably installed at the inner portion of the lower middle frame 100 and at the operation port 301, a wedge-shaped pressing block 303 is installed on the upper surface of the cover opening button 302, and a guide rod 304 is installed on the outer surface of the cover opening top block 105.

[0030] When the upper middle frame 101 is opened, the hand is inserted into the operation port 301 and the cover opening button 302 is pressed downward, so that the cover opening button 302 is rotated, the cover opening button 302 drives the wedge-shaped pressing block 303 to press the guide rod 304, and then the cover opening top block 105 is pushed to move, so that the rotating hook 103 is lifted and separated from the wedge-shaped block 104.

[0031] The cover opening top block 105 is limitingly and slidably installed, and the sliding distance is limited, when the cover opening top block 105 slides to the farthest distance, the inclined surface of the wedge-shaped pressing block 303 is still in contact with the guide rod 304, so that the wedge-shaped pressing block 303 is prevented from rotating to the lower side of the guide rod 304, and the normal use of the function is affected.

[0032] Preferably, the lower side of the upper middle frame 101 is limitingly and slidably installed in the vertical direction with a pressing plate 400, a spring 401 is installed on the upper surface of the pressing plate 400, and the end portion of the spring 401 is connected with the lower surface of the upper middle frame 101. The both sides of the pressing plate 400 are provided with a let-in slot 402, and the diameter of the let-in slot 402 is greater than the diameter of the rubber roller.

[0033] When the upper middle frame 101 is closed, the bottom of the pressing plate 400 supports the top of the lower middle frame 100, so that the spring 401 is compressed and stored with power, when the cover opening top block 105 pushes the rotating hook 103 to separate from the wedge-shaped block 104, the spring 401 stored with power is released to push the upper middle frame 101 upward, so that the rotating hook 103 and the wedge-shaped block 104 are dislocated, and the re-engagement is avoided, and then the upper middle frame 101 can be opened by one hand.

[0034] Through the arrangement of the let-in slot 402, the pressing plate 400 can be prevented from contacting the rubber roller, and the use of the rubber roller is affected.

[0035] Preferably, a limiting column 500 is installed on the upper surface of the pressing plate 400, and the limiting column 500 is arranged in the inner portion of the spring 401.

[0036] Through the arrangement of the limiting column 500, the spring 401 can be limited, and the bending deformation of the spring 401 in the process of frequent compression is avoided, and the service life of the spring 401 is improved.

[0037] Preferably, a reinforcing rib 600 is installed on the outer surface of the fixed rod 201.

[0038] Due to the pulling force of the tension spring 203 on the fixed rod 201, the structural strength can be improved by arranging the reinforcing ribs 600, so as to avoid damage under the pulling of the tension spring 203.

[0039] The above is a detailed description of the utility model in combination with specific embodiments, which cannot be considered as limiting the specific embodiments of the utility model to these descriptions. For ordinary skilled persons in the technical field to which the utility model belongs, without departing from the concept of the utility model, some equivalent substitutions or obvious modifications can be made, and the performance or use is the same, which should be considered as belonging to the patent protection range determined by the submitted claims of the utility model.
