[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a drop-proof portable power supply device includes a device body 1, a shell 2 is provided on the outside of the device body 1, a shock-absorbing mechanism 3 is provided between the upper and lower surfaces of the device body 1 and the shell 2, and the shock-absorbing mechanism 3 includes a damping rod 301, one end of the damping rod 301 is connected to the device body 1, and the other end of the damping rod 301 is connected to the shell 2. A spring 302 is sleeved on the outer surface of the damping rod 301, and the two ends of the spring 302 are respectively connected to the device body 1 and the shell 2. The spring 302 can buffer the impact force, and the damping rod 301 can reduce the shaking amplitude, thereby achieving a shock-absorbing effect.

[0024] A buffer rod 4 is fixedly connected to the side of the device body 1, and the end of the buffer rod 4 away from the device body 1 is fixedly connected to the shell 2. The inner wall of the shell 2 is slidably connected to a protective plate 5. The protective plate 5 is located on one side of the inside of the shell 2 and is provided with a transmission mechanism 6. The transmission mechanism 6 includes a first tooth plate 601, and one side of the first tooth plate 601 is meshedly connected to the gear 602. The outer surface of the gear 602 is also meshedly connected to the second tooth plate 603. The side of the second tooth plate 603 away from the gear 602 is fixedly connected to the protective plate 5. Through the meshing relationship between the three components, when the first tooth plate 601 moves downward, it will drive the gear 602 to rotate, thereby driving the second tooth plate 603 to move upward. Similarly, When the first tooth plate 601 moves upward, the second tooth plate 603 will be mobilized to move downward. The outer surfaces of the first tooth plate 601 and the second tooth plate 603 are both slidably connected to the shell 2. The lower part of the first tooth plate 601 is fixedly connected to a stopper 604. The shape of the stopper 604 is rectangular. When the first tooth plate 601 moves to the uppermost position, the stopper 604 can be stuck at the inner top wall of the shell 2 to prevent the first tooth plate 601 from moving upward excessively, thereby increasing stability. A pin 605 is fixedly connected to one side of the gear 602. The outer surface of the pin 605 is rotatably connected to the shell 2. The gear 602 is fixed by the pin 605 so that it can only rotate in place and cannot change its position.

[0025] A lifting mechanism 7 is provided on the upper part of the transmission mechanism 6. The lifting mechanism 7 includes a movable plate 701. The lower surface of the movable plate 701 is fixedly connected to the top of the first tooth plate 601. The upper part of the movable plate 701 is hinged with a handle 702. The four first tooth plates 601 are all connected together through the movable plate 701, so that the four first tooth plates 601 can move synchronously when moving up and down. The handle 702 is provided to facilitate the lifting of the movable plate 701 upward.

[0026] A fixing mechanism 8 is provided on the outside of the lifting mechanism 7, and the fixing mechanism 8 includes a first mounting plate 801. The outer surface of the first mounting plate 801 is fixedly connected to the movable plate 701, and the outer surface of the outer shell 2 is fixedly connected to the second mounting plate 802. The first mounting plate 801 and the second mounting plate 802 are detachably connected. When the movable plate 701 drives the first mounting plate 801 to move to the lower part, the first mounting plate 801 and the second mounting plate 802 can be fixed by bolts, thereby fixing the movable plate 701 to the outer shell 2.

[0027] The interior of the shell 2 is hinged with an opening and closing plate 9, and there are multiple shock-absorbing mechanisms 3 and buffer rods 4. When the device falls, the shock-absorbing mechanism 3 is used to absorb the shock of the device body 1 to reduce the damage to the device body 1. At the same time, the side is buffered by the buffer rod 4. The material of the buffer rod 4 is rubber and can undergo a certain deformation. There are two protective plates 5, which are respectively arranged on the front and back of the device body 1. When in use, the protective plates 5 are opened so as not to affect the wiring on the front and back and the operation and observation of the device body 1. The opening and closing plate 9 is set at a position opposite to the heat dissipation holes on the device body 1. The opening and closing plate 9 can be opened by rotating it. It is convenient for heat dissipation when in use. When not in use, the opening and closing plate 9 is closed to protect the internal device body 1 to prevent dust from entering.

[0028] It should be noted that in actual use of the device, the lifting mechanism 7 is pressed downward, and the lifting mechanism 7 drives the first tooth plate 601 to move downward, so that the second tooth plate 603 drives the protective plate 5 to move upward, thereby achieving the effect of opening the two protective plates 5, thereby exposing the front and back of the shell 2. The lifting mechanism 7 is fixed by the fixing mechanism 8, thereby fixing the two protective plates 5 for easy use and achieving the effect of quick opening.

[0029] When the device needs to be moved or is to be put away, all the connecting wires are unplugged first, the lifting mechanism 7 is pulled upward, and the two protective plates 5 are slid downward through the transmission mechanism 6 to protect the front and back of the device body 1, thereby protecting the front and back of the device body 1. During the movement, the device can be lifted by grasping the handle 702 located above the shell 2, so as to achieve the effect of being easy to carry. When the device is hit by an external force, the shock absorbing mechanism 3 is used to absorb the shock of the device body 1 to reduce the damage to the device body 1. At the same time, the impact force is buffered by the buffer rod 4 on the side, thereby protecting the device body 1.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
