[0022] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0023] Combine the following Figures 1 to 4 The utility model is described in detail.
[0024] A rotationally molded distribution box comprises a main body 1, a closed door 101 is connected to one side of the main body 1, protective cavities 102 are arranged on both sides of the main body 1, a buffer assembly is arranged in the middle of the protective cavity 102, a protective plate 2 is connected to the middle of the protective cavity 102, two buffer assemblies are cross-arranged between the protective cavity 102 and the protective plate 2, a hinge block 105 is arranged on one side of the middle of the protective cavity 102, a movable hinge block 203 is connected to one side of the protective plate 2, two ends of the buffer assembly are respectively connected to the hinge block 105 and the movable hinge block 203, and the buffer assembly swings along the hinge block 105.
[0025] First, the electronic components are uniformly installed in the body 1, and then the interior is protected by closing the door 101, which can be opened to inspect the internal electronic components.
[0026] Furthermore, the buffer assembly includes a first buffer plate 103 and a second buffer plate 104, the first buffer plate 103 is arranged in the middle of the protective cavity 102, and the second buffer plate 104 is arranged in the middle of the protective cavity 102 near the first buffer plate 103, the protective plate 2 is movably connected in the protective cavity 102 through sliders 201 on both sides, the first buffer plate 103 and the second buffer plate 104 are arranged in a cross-oblique arrangement, and a movable hinge block 203 is arranged at the protective cavity 102 where the second buffer plate 104 is attached, and both ends of the first buffer plate 103 and the second buffer plate 104 are respectively connected to the hinge block 105 and the movable hinge block 203, a reset spring is arranged on one side of the first buffer plate 103 and the second buffer plate 104, and a groove for connecting the reset spring is arranged on the inner wall of the protective cavity 102.
[0027] When the main body 1 is hit by a hard object, it will hit the protective plate 2. When the protective plate 2 is subjected to force, it will move into the protective cavity 102 through the sliders 201 on both sides. When the protective plate 2 moves into the protective cavity 102, it will pressurize the first buffer plate 103 and the second buffer plate 104 connected on one side, so that the first buffer plate 103 and the second buffer plate 104 will deflect along the hinge block 105 at the bottom. When the first buffer plate 103 and the second buffer plate 104 deflect, one side of the spring will be compressed. Through the deflection of the first buffer plate 103 and the second buffer plate 104 and the pressure on the spring, the impact caused by the collision will be buffered to a certain extent, thereby preventing the impact caused by the collision from damaging the outer shell of the main body 1 and causing external humid air to enter the interior and affect the electronic components.
[0028] At the same time, when the impact is too great, the first buffer plate 103 and the second buffer plate 104 will completely vertically overlap with the protective cavity 102 and the protective plate 2, thereby increasing the protective strength of the outer shell of the main body 1, so that after the first buffer plate 103 and the second buffer plate 104 deflect and buffer a certain force, the remaining impact and force are protected by overlapping reinforcement, making the protection of the main body 1 more stable.
[0029] Furthermore, the protective plate 2 also includes a slider 201 and a lifting slot 202 . The slider 201 is arranged on both sides of the protective plate 2 . The lifting slot 202 is arranged on one side of the protective plate 2 near the top. The movable hinge block 203 is slidably connected in the lifting slot 202 .
[0030] When the first buffer plate 103 and the second buffer plate 104 are deflected, the movable hinge block 203 at the top will move along the lifting slot 202 to cooperate with the deflection, so as to cooperate with the change of the axial length of the first buffer plate 103 and the second buffer plate 104 when they are deflected vertically along the hinge block 105.
[0031] The following is a specific implementation process of the utility model. First, the electronic components are uniformly installed in the body 1, and then the interior is protected by the closed door 101. At the same time, it can be opened to inspect the internal electronic components. When the body 1 is hit by a hard object, it will hit the protective plate 2. When the protective plate 2 is subjected to force, it will move toward the protective cavity 102 through the sliders 201 on both sides. When the protective plate 2 moves into the protective cavity 102, it will press the first buffer plate 103 and the second buffer plate 104 connected on one side, so that the first buffer plate 103 and the second buffer plate 104 will deflect along the hinge block 105 at the bottom, and the first buffer plate 103 and the second buffer plate 104 will be deflected. When the first and second buffer plates 103 and 104 are deflected, one side of the spring will be compressed. Through the deflection of the first buffer plate 103 and the second buffer plate 104 and the pressure on the spring, the impact caused by the collision will be buffered to a certain extent, so as to prevent the impact caused by the collision from damaging the shell of the main body 1 and causing external humid air to enter the interior and affect the electronic components. At the same time, when the impact is too large, the first buffer plate 103 and the second buffer plate 104 will be completely vertically overlapped with the protective cavity 102 and the protective plate 2, so as to increase the protection strength of the shell of the main body 1, so that after the first buffer plate 103 and the second buffer plate 104 deflect and buffer a certain force, the remaining impact and force can be protected by overlapping reinforcement, so that the protection of the main body 1 is more stable.
[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
