[0030] Embodiment 1

[0031] Figures 1-4 Shown is a schematic structural diagram of the overall buffering method as a specific embodiment of the present utility model. Figures 1-4 Among them, it includes a box body 1 and a sliding limit groove 2 opened inside the box body 1. An inner buffer mechanism is slidably arranged in the sliding limit groove 2, and an outer buffer mechanism is installed at the lower end of the box body 1.

[0032] The inner buffer mechanism includes a buffer support frame 3, side buffer blocks 301, and a bottom buffer pad 302. Among them, the buffer support frame 3 is slidably installed inside the sliding limit groove 2. There are several side buffer blocks 301, which are evenly distributed on opposite sides of the buffer support frame 3. The bottom buffer pad 302 is fixedly installed in the lower half of the inside of the box body 1. The side buffer blocks 301 are used for buffering on the peripheral side inside the device, and the bottom buffer pad 302 is used for buffering at the bottom end inside the device.

[0033] The outer buffer mechanism includes an insertion support groove 8, an insertion leg 801, a moving support groove 802, a telescopic spring 806, a buffer connection head 807, and an auxiliary limit ring 808. Among them, the insertion leg 801 is fixedly arranged at the lower end of the box body 1, and the insertion leg 801 is inserted into the insertion support groove 8. The buffer connection head 807 is slidably installed inside the moving support groove 802. The moving support groove 802 is opened in the box body 1 and the insertion leg 801, and one end of the buffer connection head 807 extending out of the moving support groove 802 is located between the insertion leg 801 and the insertion support groove 8. One end of the buffer connection head 807 located inside the moving support groove 802 is installed with a telescopic spring 806, and the other end of the telescopic spring 806 is fixedly installed on the upper half of the inner wall of the moving support groove 802. An auxiliary limit ring 808 is installed on the outer side of the upper half of the buffer connection head 807, and the auxiliary limit ring 808 is slidably located inside the limit groove provided in the lower half of the moving support groove 802.

[0034] When the device is running, through the simultaneous buffering support of the internal buffering mechanism inside the box body 1 and the external buffering mechanism outside the box body 1, the overall device can be buffered and supported both inside and outside. Specifically, the buffering support frame 3 is placed through the sliding guidance and limit support in the sliding limit groove 2, and then, under the simultaneous support of the bottom buffer pad 302 and the side buffer block 301, and by setting the bottom buffer pad 302 as an elastic material and the buffering support frame 3 as a flexible material, the two can unload the force when receiving pressure, thereby providing buffering support for the inside of the device from multiple angles. At the same time, the buffering connection head 807, the auxiliary limit ring 808, and the telescopic spring 806 are limited and elastically moved inside the moving support groove 802, so as to buffer and support the outside of the device, and under the plug-in support of the plug-in leg 801 and the plug-in support groove 8, when multiple box bodies 1 are stacked and placed, the effect of simultaneous external buffering can be achieved, so that the device can be buffered from both inside and outside, improving its stability and reliability during transportation and placement.

[0035] Figure 3 The figure shows a schematic structural diagram of the top buffering method of the internal buffering mechanism as a specific embodiment of the present utility model. Figure 3 In this case, the internal buffering mechanism further includes a top plate 7 and a top buffer pad 303. Among them, the top plate 7 is used to close the top of the box body 1, and a top buffer pad 303 is installed at one end of the top plate 7, and the top buffer pad 303 is used for buffering the upper end of the device.

[0036] The top plate 7 is inserted into the sliding limit groove 2 through the insertion block 4, and the insertion block 4 is fixedly installed on the same side of the top plate 7 as the top buffer pad 303.

[0037] By inserting and placing the top plate 7 on the top of the box body 1, and under the buffering support of the top buffer pad 303 from the top, the diversity and stability of the angles during buffering inside the device can be further improved.

[0038] Figure 4 The figure shows a three-dimensional structural diagram of the external buffering mechanism as a specific embodiment of the present utility model. Figure 4 In this case, the external buffering mechanism further includes a limit support rod 803, a sliding support cylinder 804, and a limit block 805. Among them, the limit block 805 is installed at the lower end of the limit support rod 803, the limit block 805 is slidably connected to the sliding support cylinder 804 and extends into it, and the limit block 805 is inside the sliding support cylinder 804.

[0039] The upper end of the limit support rod 803 is installed on the upper half of the inner wall of the moving support groove 802, the lower end of the sliding support cylinder 804 is installed on the upper end of the buffering connection head 807, and both the limit support rod 803 and the sliding support cylinder 804 are located in the middle of the telescopic spring 806.

[0040] The plug-in support groove 8 is opened at the upper end of the top plate 7. The plug-in leg 801 and the plug-in support groove 8 are used for the buffer support when two boxes 1 and the top plate 7 are stacked and placed.

[0041] Through the mutual cooperation of the sliding support cylinder 804 and the telescopic spring 806, the stable and reliable operation of the outer buffer mechanism can be ensured. For example, when the buffer connection head 807 is pressed and moves upward, the telescopic spring 806 moves upward and contracts, causing the sliding support cylinder 804 to move upward under the guidance of the limit support rod 803. Then, through the elastic reset of the telescopic spring 806, the effect of simultaneously resetting the buffer connection head 807 and the sliding support cylinder 804 is achieved. At the same time, under the limit support of the limit block 805 on the sliding support cylinder 804, the stability of the moving distance of the sliding support cylinder 804 and the telescopic spring 806 is ensured, so as to achieve a stable buffer distance support for the buffer connection head 807, thereby improving the stable and reliable operation of the outer buffer mechanism.

[0042] Figure 1 and Figure 3 Shown is a schematic diagram of the closed structure of the device as a specific embodiment of the present invention. Figure 1 and Figure 3 In [the figure], rotation limit frames 5 are rotatably arranged inside the support grooves opened on opposite sides of the box 1. One end of the rotation limit frame 5 is inserted and limited in the insertion grooves inside the limit support grooves 6 opened on opposite sides of the top plate 7.

[0043] Through the insertion and limitation of the box 1 and the top plate 7 by the rotation limit frame 5, the effect of closing and limiting the top of the box 1 is achieved, which can ensure the stable connection of the overall device and improve the connection stability during the operation of the internal and external buffer mechanisms of the device.

[0044] Working principle: The buffer support frame 3 in the internal buffer mechanism is placed through the sliding guidance and limit support of the sliding limit groove 2 inside the box 1. Then, through the simultaneous support of the bottom buffer pad 302 and the side buffer blocks 301 on both sides of the buffer support frame 3, and by setting the bottom buffer pad 302 as an elastic material and the buffer support frame 3 as a flexible material, the two can unload force when receiving pressure, thereby providing multiple-angle buffering inside the device. At the same time, the buffer connection head 807, the auxiliary limit ring 808, and the telescopic spring 806 in the outer buffer mechanism are limited and elastically moved inside the moving support groove 802, so as to provide buffer support on the outside of the device. And through the plug-in support of the plug-in leg 801 and the plug-in support groove 8, the effect of simultaneous outer buffering can be achieved when multiple boxes 1 are stacked.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
