[0036] like Figure 5 As shown, inner grooves 11 are provided at the center of the cushion layer 8 and at the corners around the bottom surface of the bottom liner 5. The overall shape of the inner groove 11 is a right triangle, and the two right-angled sides of the inner groove 11 are parallel to the corresponding side edges of the bottom liner 5;

[0037] A first partition 12 is provided between each two adjacent cushion layers 8, and the four first partitions 12 are respectively located at the center of the side of the bottom cushion 5. When the shell 1 is placed on the top of the cushion layer 8, the hand can be inserted into the inside of the first partition 12, and then the shell 1 is lifted from the top of the bottom cushion 5 or placed on the top of the bottom cushion 5, ensuring the rapidity and efficiency of the disassembly and assembly of the shell 1 and the bottom cushion 5.

[0038] like Figure 1 As shown, the shell 1 includes a first half-groove and a second half-groove, the pad 2 is located between the first half-groove and the second half-groove, and the corresponding sides of the first half-groove and the second half-groove are provided with a chain buckle device 13, and the first half-groove and the second half-groove are correspondingly buckled through the chain buckle device 13; the first half-groove and the second half-groove correspond to each other, so that the entire pad 2 is wrapped together, and the integration effect between the shell 1 and the pad 2 is increased by the chain buckle device 13, so that the round electrical appliance and the pad 2 and the shell 1 are integrated.

[0039] The outer sides of the first liner and the second liner are both provided with transverse grooves 14 corresponding to and matching the chain buckle device 13, and the depth of the transverse grooves 14 is less than the thickness of the side of the liner 2. After the clamping frame 19 of the chain buckle device 13 is correspondingly buckled with the transverse grooves 14, the shell 1 and the liner 2 are combined and connected, which increases the integrity and stability of the entire packaging device.

[0040] like Figure 2 As shown, the chain buckle device 13 includes a press frame 15, a spring 16 is arranged inside the press frame 15, one end of the spring 16 is fixedly connected to the inner side of the press frame 15, and a stopper 17 is arranged at the other end of the spring 16. A clamping head 18 is arranged at one end of the press frame 15, and a clamping frame 19 is slidably sleeved on the outer side of the clamping head 18. A slide groove 20 that is slidably matched with the clamping head 18 is arranged inside the clamping frame 19, and the clamping head 18 and the press frame 15 are arranged as a whole;

[0041] A connecting frame 21 is provided on the top of the pressing frame 15, the bottom end of the connecting frame 21 is fixedly connected to the pressing frame 15, and a collar 22 is provided on the other end of the connecting frame 21. The two chain buckle devices 13 correspond to each other through the collar 22, and the screw rod passes through the collars 22 of the two chain buckle devices 13, so that the two chain buckle devices 13 are combined together, and the stability of the entire packaging device is ensured by the chain buckle device 13.

[0042] like Figure 2 As shown, the chain buckle device 13 also includes a cut block 23, and the sides corresponding to each other of the cut block 23 and the bracket 19 are provided with cut surfaces, and the cut block 23 and the bracket 19 slide correspondingly through the cut surfaces; when the cut surface of the bracket 19 is in contact with the cut surface of the cut block 23, the pressing frame 15 continues to move, and the cut surface causes the bracket 19 and the cut block 23 to move out of position, and while the bracket 19 slides on the surface of the clamping head 18, the bottom end of the bracket 19 gradually enters the interior of the transverse groove 14, and the outer shell 1 is buckled with the transverse groove 14 of the pad 2 through the bracket 19 of the chain buckle device 13. Among them, an elastic member is arranged inside the slide groove 20, and the elastic member is located at the top and bottom of the clamp head 18. When the clamp head 18 and the bracket 19 are misaligned, the clamp head 18 will squeeze and stretch the elastic member while sliding inside the slide groove 20. When the force applied to the surface of the connecting frame 21 is released, the elastic force of the elastic member and the matching effect between the clamp head 18 and the slide groove 20 will restore the bracket 19 to its original state.

[0043] The first half-groove and the second half-groove have corresponding side edges provided with slots corresponding to the connecting frame 21, the bottom of the connecting frame 21 is located inside the slots, and the overall appearance of the pressing frame 15 and the connecting frame 21 are both set to an L-shaped structure. The connecting frame 21 can slide inside the housing 1 through the slots, and the L-shaped structure enhances the overall strength of the connecting frame 21 and the pressing frame 15, thereby increasing the service life of the connecting frame 21 and the pressing frame 15 during the packaging process.

[0044] like Figure 4 As shown, the inner wall of the placement groove 3 is fixedly installed with a plurality of vertically placed reinforcing ribs 24, and the inner groove wall of the placement groove 3 is fixedly installed with a plurality of horizontally placed frame ribs 25, and the inner side of the frame ribs 25 is provided with an arc groove 26, and the reinforcing ribs 24 and the frame ribs 25 are both integrated with the pad 2. The arc groove 26 corresponds to the shape of the circular electrical appliance, and the first pad and the second pad can be wrapped on the outer surface of the circular electrical appliance through the arc groove 26. When the pad 2 is used to package the circular electrical appliance, the plurality of horizontally placed frame ribs 25 can support the circular electrical appliance, and the vertically placed reinforcing ribs 24 enhance the vertical strength of the pad 2, and also increase the toughness of the frame ribs 25 in the horizontal direction, so as to provide good protection and support for the circular electrical appliance. Exemplarily, the overall shape of the arc groove 26 can also be set to a square structure, and the square-structured arc groove 26 can be used to package the square-structured electrical appliance. Different arc grooves 26 are selected according to the shape of the electrical appliance, which increases the applicability of the entire packaging device.

[0045] like Figure 5 and Figure 6 As shown, a material-saving groove is arranged at the center of the circular retaining ring 7, and the material-saving groove runs through the entire bottom gasket 5, and is located at the center of the bottom gasket 5; the material-saving groove can reduce unnecessary material usage and reduce costs. When the circular electrical appliance impacts the top of the circular retaining ring 7, the bottom gasket 5 is deformed under the action of the impact, and the impact force can be dispersed, thereby avoiding the phenomenon of local force damage to the bottom gasket 5.

[0046] The overall shape of the material saving trough is set to a cylindrical structure, and the material saving trough and the four corners of the inner wall of the bottom liner 5 are all provided with second partitions, and the thickness of the second partition is less than the thickness of the bottom liner 5. When the bottom liner 5 or the bottom frame 9 is seriously damaged, the entire bottom liner 5 can be taken out from the inside of the bottom frame 9 through the second partition, and then the bottom liner 5 or the bottom frame 9 can be replaced as needed, and the bottom liner 5 and the bottom frame 9 can be re-installed correspondingly, so as to facilitate the sustainable packaging effect of the entire packaging device.

[0047] Working principle of the present invention:

[0048] Refer to the instruction manual Figure 1-6 When installing the entire round appliance, after placing the first half-groove and the second half-groove correspondingly, the first gasket and the second gasket are placed inside the first half-groove and the second half-groove respectively, and the round appliance is placed inside the placement groove 3 of the first gasket. The first gasket supports the round appliance through the arc groove 26 on the inner side of the frame rib 25, and the arc groove 26 corresponds to the shape of the round appliance. Then, the second half-groove with the second gasket is placed at the corresponding opening of the first half-groove. At this time, the first gasket and the second gasket are both wrapped around the outer surface of the round appliance through the placement groove 3.

[0049] Pull the connecting frame 21, the connecting frame 21 drives the pressing frame 15 to slide inside the groove, and the stopper 17 cooperates with the pressing frame 15, and the pressing frame 15 squeezes the spring 16. At this time, the pressing frame 15 drives the clamping frame 19 to gradually approach the cut block 23. When the cut surface of the clamping frame 19 fits the cut surface of the cut block 23, the pressing frame 15 continues to move, and the cut surface causes the clamping frame 19 and the cut block 23 to move out of position. At this time, the bottom end of the clamping frame 19 gradually moves toward the transverse groove 14, and the clamping head 18 presses the elastic member at the top of the slide groove 20. Pressurization is applied to stretch the elastic member at the bottom of the slide groove 20. When the sleeve rings 22 of the two connecting frames 21 correspond to each other, the connecting frame 21 is stopped from being pulled. After the screw passes through the sleeve rings 22 of the two connecting frames 21, the connecting frame 21 is loosened. The combination of the two chain buckle devices 13 makes the first half-groove and the second half-groove one side correspondingly connected. In the same way, the two chain buckle devices 13 on the other side of the first half-groove and the second half-groove are connected correspondingly, thereby completing the preliminary packaging of the round electrical appliance.

[0050] First, the recessed portion 10 at the bottom of the bottom pad 5 is placed inside the bottom frame 9, and then the circular partition 6 is placed on the top surface of the circular baffle ring 7. Then, the bottom end of the initially packaged circular appliance is placed on the top of the bottom pad 5, the bottom strip 4 and the cushion layer 8 are placed correspondingly, and the bottom end of the circular appliance is on the top of the circular partition 6. Then, the packaging bag is wrapped around the outer shell 1 and the outside of the bottom pad 5, thereby completing the packaging of the circular appliance. When the packaged circular appliance falls, the bottom pad 5 itself not only plays a buffering role for the circular appliance, but the outer shell 1 is tightly fastened to the surface of the pad 2 through the chain buckle device 13, and the placement groove 3 on the inner side of the pad 2 is tightly fastened to the surface of the circular appliance through multiple frame strip ribs 25. The impact force of the circular appliance when it falls is transmitted to the cushion layer 8 through the pad 2, and the impact force of the bottom end of the circular appliance is transmitted to the bottom pad 5 through the circular partition 6 and the circular baffle ring 7. The bottom pad 5 further increases the buffering effect of the circular appliance to prevent the bottom end of the circular appliance from being damaged after falling.

[0051] When disassembling the entire packaging device, after cutting the packaging bag, the entire liner 2 and the shell 1 can be lifted through the first partition groove 12, which is convenient for separating the liner 2 from the bottom liner 5, and then the circular partition plate 6 is removed from the top of the circular retaining ring 7, and the bottom liner 5 is taken out from the top of the bottom frame 9 through the second partition groove. The damaged bottom liner 5, circular partition plate 6 and bottom frame 9 can be replaced, which is convenient for the next packaging of the round electrical appliance. First, the shell 1 is placed horizontally, and after the screw is removed from the inside of the ring 22, the elastic force of the spring 16 and the elastic member restores the pressing frame 15 and the clamping frame 19 to their original state, and the two rings 22 are separated from each other until the side of the connecting frame 21 fits with the inner side of the strip groove, and then the second half-groove and the second liner are separated from the first half-groove and the first liner respectively, and the round electrical appliance is taken out, which is convenient for packaging and disassembly of the round electrical appliance at any time.

[0052] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
