Technical Field

[0001] The utility model belongs to the technical field of disassembly structures, and in particular relates to a self-disassembly type closed shell. Background Art

[0002] Sealed shells such as waterproof mobile phone cases and charging boxes are very common in daily life. They are mainly composed of a bottom shell and a top cover. The bottom shell and the top cover are usually connected with mutually adaptable buckles and buckles. In order to ensure the sealing, the buckles and buckles need to be fastened very tightly, which makes it extremely difficult to disassemble the top cover.

[0003] In the prior art, a disassembly piece is generally used to disassemble the sealed shell. The disassembly piece is inserted into the connecting gap between the bottom shell and the top cover, and the disassembly piece is pried to drive the buckle out of the locking position, so that the top cover can be successfully removed. However, since the disassembly piece itself is small in size and very easy to lose, users do not carry it with them, which makes it impossible to disassemble the sealed shell at any time, causing great trouble to users. Therefore, it is necessary to design a self-disassembling sealed shell to solve this problem. Utility Model Content

[0031] See attached Figure 1 -Attached Figure 4 A self-detachable sealed shell includes a bottom shell 1 and a top cover 2 that are interlocked, and a lever 3; the lever 3 is rotatably mounted on the side wall of the top cover 2 and abuts against the side wall of the bottom shell 1. By prying the front end of the lever 3, the rear end of the lever 3 can be driven to squeeze the bottom shell 1, thereby causing the top cover 2 to detach from the bottom shell 1.

[0032] Specifically, under normal circumstances, the bottom shell 1 and the top cover 2 are buckled together to form a closed shell, and the lever 3 is in the initial position and abuts against the side wall of the bottom shell 1; when the closed shell needs to be disassembled and opened, the front end of the lever 3 is pushed to drive the rear end of the lever 3 to squeeze the bottom shell 1, thereby making the side of the top cover 2 separate from the side of the bottom shell 1, and finally, the side of the top cover 2 is pushed around with this point as the origin, so that the top cover 2 can be removed from the bottom shell 1; when the closed shell needs to be reassembled, the lever 3 is pushed back to its original position, and then the top cover 2 is buckled to the bottom shell 1.

[0033] In summary, the utility model installs a rotatable lever 3 on the top cover 2 for squeezing the relatively arranged bottom shell 1, so that the sealed shell has the function of self-disassembly and ensures that the lever 3 is not easily lost, which is convenient for users to disassemble and assemble the sealed shell at any time, thereby improving the user experience.

[0034] It should be noted that the sealed shell can be a waterproof mobile phone case, a charging box, or other product for placing items, and the buckle structure between the bottom shell 1 and the top cover 2 belongs to the prior art, so the utility model does not limit or elaborate on it.

[0035] See attached Figure 1 -Attached Figure 4 A movable groove 20 is provided on the side wall of the top cover 2, and the movable groove 20 is recessed to correspond to the side wall of the bottom shell 1, and a first opening 201 and a second opening 202 connected to the outside are respectively provided on the top and bottom sides of the movable groove 20; the lever 3 is rotatably arranged in the movable groove 20, and when the front end of the lever 3 is moved toward the first opening 201, the rear end of the lever 3 can be driven to move toward the second opening 202 to squeeze the bottom shell 1.

[0036] Specifically, under normal circumstances, the entire lever 3 is hidden in the recessed movable groove 20; when disassembling the sealed shell, insert a finger into the movable groove 20 and pry the front end of the lever 3 toward the first opening 201. During this process, the rear end of the lever 3 simultaneously moves toward the second opening 202 to squeeze the bottom shell 1 until the side of the top cover 2 is completely driven away from the side of the bottom shell 1, and then the side of the top cover 2 is pried around with this point as the origin; when assembling the sealed shell, pry the lever 3 back into the movable groove 20, and then buckle the top cover 2 to the bottom shell 1.

[0037] In summary, the design of the movable groove 20 can, on the one hand, hide the lever 3 to improve the overall aesthetics, and on the other hand, prevent the lever 3 from protruding out of the outside and colliding with objects, thereby reducing the possibility of damage to the lever 3.

[0038] See attached Figure 1 -Attached Figure 4 A notch 21 is provided on the inner wall of the movable groove 20 , and an elastic sheet 31 with a protrusion 310 is provided at the head end of the shift bar 3 . The protrusion 310 can be engaged with or disengaged from the notch 21 as the shift bar 3 enters and exits the movable groove 20 .

[0039] Specifically, when the lever 3 is completely hidden in the movable groove 20, the protrusion 310 is engaged with the recess 21 to ensure that during the installation of the top cover 2 to the bottom shell 1, the lever 3 will not swing out of the movable groove 20 and hinder the assembly; when disassembling the sealed shell, it is necessary to forcefully pry the lever 3 to drive the protrusion 310 out of the recess 21, and then move the front end of the lever 3 toward the first opening 201.

[0040] The elastic sheet 31 can be made of plastic and has certain deformation and recovery capabilities. When the lever 3 enters and exits the movable groove 20 , the elastic sheet 31 will undergo adaptive deformation to ensure that the protrusion 310 can be smoothly separated from and engaged with the recess 21 .

[0041] See attached Figure 4 -Attached Figure 6 The cross section of the notch 21 is an inward-sunken semicircle, while the cross section of the protrusion 310 is an outward-sunken semicircle to fit the notch 21; this design can reduce the resistance between the notch 21 and the protrusion 310, facilitate the protrusion 310 to enter and exit the notch 21, and improve the operating convenience of the shift bar 3.

[0042] See attached Figure 1 -Attached Figure 6 A stopper 22 connected to the first opening 201 is also provided on the side wall of the movable groove 20, and a stopper 32 is provided on the head end of the shift bar 3; the head end of the shift bar 3 enters the movable groove 20 through the first opening 201, and when the protrusion 310 engages with the recess 21, the stopper 32 abuts against the inner wall of the stopper 22.

[0043] Specifically, the cooperation between the stopper 32 and the stopper 22 can limit the movement of the head end of the lever 3 toward the second opening 202, ensuring that during the installation of the top cover 2 to the bottom shell 1, the head end of the lever 3 will not swing out of the movable groove 20 and hinder assembly.

[0044] See attached Figure 5 -Attached Figure 6 There are various ways of rotationally connecting the lever 3 and the bottom wall of the movable groove 20, and the present utility model does not impose any restrictions on this. For the sake of easy understanding, in this embodiment, a rotating shaft 23 is provided on the bottom wall of the movable groove 20, and a rotating hole 33 is provided on the lever 3. The rotating shaft 23 and the rotating hole 33 are rotatably matched, and a fastening bolt 230 is threadedly connected to the rotating shaft 23, and one end of the fastening bolt 230 abuts against the side wall of the lever 3 to limit the rotating hole 33 from being separated from the rotating shaft 23.

[0045] Specifically, compared with other rotating structures, the coordinated use of the rotating shaft 23 , the rotating hole 33 and the fastening bolt 230 facilitates the assembly and disassembly of the shift bar 3 .

[0046] See attached Figure 5 -Attached Figure 6In the case where the notch 21 and the protrusion 310 are not provided for cooperation, the rotating shaft 23 and the rotating hole 33 can also be provided with an interference fit, so as to utilize the damping between the two to limit the rotation of the shift bar 3, and ensure that the shift bar 3 will not be separated from the movable groove 20 when no external force is applied.

[0047] See attached Figure 5 -Attached Figure 6 A notch 34 is provided on the lever 3 , and the notch 34 is connected to the movable groove 20 .

[0048] Specifically, when in use, a finger is inserted into the notch 34 through the movable groove 20 and can smoothly contact the side wall of the lever 3 to exert force, so as to facilitate the lever 3 to bend toward the first opening 201, thereby improving the convenience of operation.

[0049] See attached Figure 6 -Attached Figure 7 The side of the lever 3 facing the bottom wall of the movable groove 20 is designed to be smooth, which can reduce the friction between the lever 3 and the bottom wall of the movable groove 20 and reduce the possibility of wear of the lever 3 and the top cover 2.

[0050] See attached Figure 4 -Attached Figure 6 The side of the shift bar 3 facing the outside world is provided with anti-slip grooves 35. This design can increase the force points of the shift bar 3, making it more convenient for users to move the shift bar 3.

[0051] It should also be noted that, although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application.
