DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] For example, see Figure 1-3A power supply box with an anti-electric shock function includes a power supply box body 1, the power supply box body 1 is rotatably connected to a power supply box cover 2, a power supply box body 1 is provided with a power board 3, the power board 3 is connected to a power plug 4 through a wire, a protection mechanism 5 is provided in the inner wall of the power supply box body 1, a power connection port 6 is provided on the surface of the power supply box body 1, the protection mechanism 5 includes an air pressure tube 51, the air pressure tube 51 is provided inside the power supply box body 1, the air pressure tube 51 is connected to an air bag 52, and the air bag 52 is provided on the surface of the power supply box body 1 near the power connection port 6 The inner wall of the air pressure tube 51 is slidably connected with a slider 53, the slider 53 is fixedly connected with an electrical connection block 54, a connection block 55 is arranged inside the electrical connection port 6, a spring 56 is fixedly connected to the end of the inner wall of the air pressure tube 51 away from the air bag 52, the side of the spring 56 away from the inner wall of the air pressure tube 51 is fixedly connected to the slider 53, an elastic member 57 is fixedly connected to the surface of the power supply box body 1, the side of the elastic member 57 away from the power supply box body 1 is fixedly connected to a mounting plate 58, the elastic member 57 is an elastic telescopic rod, and the mounting plate 58 is close to the power supply box A groove is provided on one side of the box body 1, and the elastic telescopic rod is arranged in the groove of the mounting plate 58. By setting the groove, it is ensured that the elastic telescopic rod can be in the groove after being contracted, so as to ensure that the mounting plate 58 and the surface of the power box body 1 cannot be fitted due to the installation of the elastic member 57. The mounting plate 58 and the power box body 1 are movably connected by a fixing component 59. The middle part of the mounting plate 58 is thinner, and the mounting plate 58 is provided with a through hole in the same shape as the power port 6. By setting the middle thickness of the mounting plate 58, it is ensured that the mounting plate 58 cannot be fitted due to the installation of the elastic member 57. The thickness of the mounting plate 58 is too thick and affects the power connection effect of the equipment. The consistency of the through holes ensures that the plug of the electrical appliance that needs to be connected can pass through the mounting plate 58 smoothly. When power connection is required, the mounting plate 58 is moved, so that the airbag 52 is squeezed, so that the slider 53 drives the power connection block 54 to move under the joint action of the airbag 52 and the air pressure tube 51, so that the power connection block 54 is connected to the connecting block 55 and the power connection board 3 at the same time, so as to achieve the power-on effect, ensure that the equipment is in a power-off state when not in use, so as to ensure that the staff will not be electrocuted after accidentally touching it.

[0020] During use, when the staff does not need to connect electricity, the staff closes the power box cover 2. When the staff needs to connect electricity, the staff first opens the power box cover 2, and then passes the plug of the electrical appliance that needs to be connected through the through hole opened on the mounting plate 58, and drives the mounting plate 58 to move toward the surface of the power box body 1 through the plug. When the mounting plate 58 fits with the surface of the power box body 1, the mounting plate 58 is fixed to the power box body 1 through the fixing component 59, and the air bag 52 is squeezed, so that the gas inside the air bag 52 enters the interior of the air pressure tube 51, so that the air pressure The gas pressure inside the tube 51 increases, so that the slider 53 moves downward under the action of the gas pressure, and drives the power connection block 54 to move, so that the power connection block 54 is connected to the connection block 55 and the power connection board 3 at the same time, so that the equipment is powered on, thereby ensuring the normal use of the equipment that needs to be connected to the power. When use is completed, the staff releases the connection between the mounting plate 58 and the power box body 1 through the fixing component 59, and the slider 53 is reset under the drive of the spring 56, so that the power connection block 54 is not in contact with the power connection board 3, thereby ensuring that the staff will not be electrocuted when touching the outside of the power box body 1.

[0021] For example 2, please refer to Figure 1-4 On the basis of the first embodiment, the fixing assembly 59 includes a mounting block 591, which is fixedly connected to the mounting plate 58. The mounting block 591 passes through the inner wall of the mounting plate 58. The mounting block 591 is slidably connected with a trapezoidal block 592. The cross-sectional shape of the trapezoidal block 592 is a trapezoid, and the side length of the trapezoidal block 592 close to the power box body 1 is smaller than the side length away from the power box body 1. By setting the shape of the trapezoidal block 592, it is ensured that when the plug is plugged in, the inclined surface of the trapezoidal block 592 is squeezed and can first move toward the side close to the mounting block 591, and then move to the same horizontal position as the bayonet 596 and then automatically pop out to achieve the effect of automatic clamping. The trapezoidal block 592 is elastically connected to the mounting block 591 through a spring 2 593, and the trapezoidal block 592 is hinged with a connecting rod 594. The connecting rod 594 is hinged with a pressing block 595, and the number of connecting rods 594 is set to two, and when the connecting rod 594 is in the initial position, the spacing close to the trapezoidal block 592 is smaller than the spacing close to the pressing block 595. By setting the number of connecting rods 594 and the initial position, it is ensured that the movement trajectory of the connecting rod 594 after pressing the pressing block 595 can make the trapezoidal block 592 leave the bayonet 596 to achieve the expected effect. A bayonet 596 is provided inside the power box body 1, and the trapezoidal block 592 is first squeezed to move toward the side close to the mounting block 591, and after moving to the same horizontal position as the bayonet 596, it pops out under the action of spring 2 593, so that the mounting plate 58 and the power box body 1 can be relatively fixed, so as to achieve the effect of continuously powering on the equipment during use.

[0022] During use, on the basis of Example 1, when it is necessary to fix the mounting plate 58 to the power box body 1, the staff drives the mounting plate 58 to move through the plug, and drives the mounting block 591 to move during the movement. When it moves to make the trapezoidal block 592 contact the inner wall of the power box body 1, at this time, since the inclined surface of the trapezoidal block 592 first contacts the inner wall of the power box body 1, the trapezoidal block 592 is squeezed into the interior of the mounting block 591. When the trapezoidal block 592 and the bayonet 596 are at the same horizontal position, the trapezoidal block 592 enters the bayonet 596. At this time, the long side of the trapezoidal block 592 contacts the edge of the bayonet 596, so the mounting plate 58 cannot move. When it is necessary to release the limit, the staff presses the pressing block 595, so that the pressing block 595 drives the connecting rod 594 to move downward on the side close to the pressing block 595, thereby causing the connecting rod 594 to tilt, thereby causing the trapezoidal block 592 to leave the bayonet 596, thereby achieving the effect of releasing the limit.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
