[0042] Figure 25 It is Figure 24 the rotated J-J sectional view in [Specific implementation manner]
[0043] The structure of the push-button 40 type sealing box in Embodiment 1 of the present utility model is as Figures 1 to 22 shown, including a box body 10 and a lid 100. As Figures 17 to 22 shown, the inner wall at the top of the box body 10 includes a locking groove 11, and the locking groove 11 is an annular circumferential groove.
[0044] As shown Figures 1 to 16 in the figure, the lid 100 includes an upper cover 20, a lower cover 30, a disc-shaped sealing ring 31, a button 40, a lever spring mechanism 50, an exhaust check valve 60, a push-type locking and releasing mechanism 70, and two latches 80.
[0045] The button 40 is installed in a button hole 21 on the top plate of the upper cover 20. There are multiple elastic hooks at the lower part of the button 40. After the button 40 is inserted into the button hole 21, it can move up and down but will not come out. The push-type locking and releasing mechanism 70 of the button includes a rotating tooth part 71, a vertical shaft 72, a spline hole 73, an end face gear 74, and an end face ratchet 75 that are vertically arranged and coaxial.
[0046] The moving end of the push-type locking and releasing mechanism 70 is fixed to the button 40, and the fixed end of the push-type locking and releasing mechanism 70 is fixed to the bottom plate 20A of the upper cover 20.
[0047] The lower cover 30 includes a bottom cover 30A and a lever seat 30B. The lever seat 30B includes a base 32 and two groups of brackets 30C. The bottom cover 30A includes a bearing hole 35 for fixing the base 32. There are two card slots 36 in the bearing hole 35. There are two protrusions 37 on the edge of the base 32. The two protrusions 37 are screwed into the two card slots 36 to realize the snap connection between the base 32 and the bearing hole 35 of the bottom cover 30A. The disc-shaped sealing ring 31 is irreversibly embedded in the groove around the 30A through secondary injection molding.
[0048] The lever spring mechanism 50 includes a central spring 51 and two levers 50A. The lever 50A includes a lever arm 52 and a cam 53. There is a rotating shaft 54 at each axial end of the cam 53. The lever arm 52 is orthogonal to the axis of the cam 53, and the lower end of the lever arm 52 is connected to the cam 53.
[0049] Each group of brackets 30C includes two vertical plates 33. There are 4 vertical plate holes 23 on the bottom plate 20A of the upper cover 20. The vertical plates 33 pass through the vertical plate holes 23 from bottom to top. There is a hinge hole 34 at the upper end of the vertical plate 33. The two rotating shafts 54 of the cam 53 are respectively inserted into the hinge holes 34 of the two vertical plates 33 of the corresponding group of brackets 30C. The central spring 51 is arranged between the bottom plate 20A of the upper cover 20 and the lower cover 30. The elastic force of the central spring 51 separates the lower cover from the upper cover. The upper end of the lever arm 52 abuts against the button 40, and the outer contour of the cam 53 abuts against the bottom plate 20A of the upper cover 20. The centers of the two groups of brackets 30C are respectively offset from the axis of the button 40 and are centrosymmetric with respect to the axis of the button 40. The two latches 80 are also centrosymmetric with respect to the axis of the button 40. There are latch holes 22 corresponding to the latches 80 on the side wall of the upper cover 20, and there are sliding grooves 27 corresponding to the latches 80 in the inner cavity of the upper cover 20. The latches 80 are arranged in the corresponding sliding grooves 27 and are driven by the lever 50A of the lever spring mechanism 50.
[0050] The driving structure of the lever 50A and the latch 80 is as follows. There is a transverse pin 56 on the outer side of the middle part of the lever arm 52 of the lever 50A. The latch 80 is L-shaped, and there is a lever 81 extending upward at the rear. There is a vertically arranged sliding groove 82 on the lever 81. The transverse pin 56 in the middle of the lever arm 52 is inserted into the vertical sliding groove 82 at the rear of the latch 80. When the button 40 is pressed down, the projection of the moving direction of the upper end of the lever arm 52 on the plane where the latch 80 is located is the same as the moving direction of the driven latch 80. The front end of the latch 80 extends out of the corresponding latch hole 22 and is inserted into the locking groove 11 on the inner wall of the top of the box body 10. When the box cover 100 is sealed, the box cover 100 is locked on the top of the box body 10. When the button 40 is released and rebounds, the transverse pin 56 on the lever arm 52 drives the latch 80 to retract, the front end of the latch 80 disengages from the locking groove 11 of the box body 10, and the box cover 100 can be opened.
[0051] In addition, there is a transverse arm 55 at the upper end of the lever arm 52. There is a first protrusion 41 protruding downward on the bottom surface of the top plate of the button 40 corresponding to the lever 50A. The bottom surface of the first protrusion 41 includes a first inclined surface 42 that is higher on the inner side and lower on the outer side. The first inclined surface 42 of the first protrusion 41 presses on the transverse arm 55 of the corresponding lever 50A.
[0052] There is a second protrusion 24 corresponding to the lever 50A on the top surface of the bottom plate 20A of the upper cover 20. The top surface of the second protrusion 24 includes a second inclined surface 25 that is lower on the inner side and higher on the outer side. The cam 53 of the lever 50A presses on the second inclined surface 25 of the corresponding second protrusion 24.
[0053] The upper end of the vertical shaft 72 of the push-button lock and release mechanism 70 is fixed in the middle of the top plate of the button 40. The rotating gear member 71 is rotatably installed at the lower part of the vertical shaft 72. The spline hole 73 is located in the middle of the bottom plate 20A of the upper cover 20. The end face gear 74 is located on the bottom surface of the bottom plate 20A of the upper cover 20. The end face ratchet 75 is located in the middle of the top surface of the base 32 of the lever seat 30B. The structures and principles of the lever spring mechanism 50 and the push-button lock and release mechanism 70 in Embodiment 1 of the present invention are the same as those of the lever spring mechanism and the push-button lock and release mechanism in the utility model with the patent number CN201420298125.2 in the prior art, and will not be described in detail here.
[0054] The push-button lock and release mechanism in Embodiment 1 of the present invention adopts the push-button lock and release mechanism of the utility model with the patent number CN201420298125.2 in the prior art. However, in practice, in order to simplify the structure of the push-button lock and release mechanism and reduce the cost of the push-button lock and release mechanism, the push-button lock and release mechanism can also adopt a general self-locking push-button spring lock.
[0055] The exhaust check valve 60 is arranged at the lower part of the bottom cover 30A. The air inlet 61 of the exhaust check valve 60 is located below the bottom cover 30A, and the air outlet 62 of the exhaust check valve is located at the upper part of the bottom cover 30A, facilitating the discharge of the pressurized gas in the box body 10.
[0056] The structure of the button 40 - type sealed box in Embodiment 1 of the present utility model is as Figures 23 to 25 shown. The difference from Embodiment 1 is only that the locking groove 11 is a radial hole. Since the box cover 100 is a round cover, an anti - rotation structure needs to be provided between the box cover 100 and the box body 10. That is, there are two positioning grooves 12 on the inner wall of the top of the box body 10, and two radial positioning bosses 26 on the upper cover 20 of the box cover 100. If the box cover 100 is a non - round cover and can be anti - rotated when cooperating with the non - round box body 10, then there is no need to additionally provide an anti - rotation structure.
