[0008] As a preferred technical solution of this utility model: there are several circular holes, and the several circular holes are respectively arranged on one side of the outer wall of sleeve two and sleeve three. The diameter of the circular holes is smaller than that of the sphere, and the inner wall of the circular holes is in contact with the inner wall of the sphere.

[0009] As a preferred technical solution of this utility model: the number of the telescopic components is eight, and the eight telescopic components are respectively arranged on both sides of the outer wall of the protective block one.

[0012] As a preferred technical solution of this utility model: the number of honeycomb holes is several, and the shape of the several honeycomb holes is hexagonal.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This shockproof and drop-resistant power adapter, through its honeycomb design, uses several hexagonal honeycomb holes to disperse and dissipate the impact of a fall on the second protective block when it approaches the first protective block. Simultaneously, when replacing the honeycomb holes, pressing the fixing post causes the outer wall of the spring piece to disengage from the inner wall of the slot. After disengaging, the outer wall of the spring piece compresses, causing the fixing post to contact the push plate. As the push plate moves towards the slide groove, the spring compresses. Releasing the fixing post allows it to pop out of the circular groove's inner cavity under the spring's compression and rebound, thus enabling quick replacement of the honeycomb holes.

[0015] 2. This shockproof and drop-resistant power adapter, through the design of the circular hole, sphere, and spring plate 2, allows for the following installation and fixation when the buffer assembly, protective block 1, protective block 2, circular groove, locking slot, spring 1, sliding groove, and push plate are installed: pressing the sphere causes it to move closer to the inner wall of the connecting rod under the compression of spring plate 2. Then, when the connecting rod extends into the inner cavity of sleeve 3 and the sphere is released, the sphere will then fit into the circular hole with a diameter smaller than the sphere under the compression and rebound of spring plate 2. This achieves the fixation of the buffer assembly, protective block 1, protective block 2, circular groove, locking slot, spring 1, sliding groove, and push plate after installation. The same operation can also be used to adjust the length and width of the power adapter body using the telescopic assembly. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 6 A shockproof and drop-resistant power adapter includes a power adapter body 1, a protective block 2 on the outer wall of the power adapter body 1, a protective block 3 slidably connected to the inner wall of the protective block 2, a circular groove 4 on the outer wall of the protective block 2, a buffer component 5 on the top of the protective block 2, a slot 6 and a sliding groove 8 on the inner wall of the circular groove 4, one end of a spring 7 fixedly connected to the inner wall of the circular groove 4, a push plate 9 fixedly mounted on the other end of the spring 7, and a telescopic component 10 on the outer wall of the protective block 2.

[0025] The buffer assembly 5 includes a fixed post 501, a spring piece 502 is fixedly mounted on the outer wall of the fixed post 501, and an mounting plate 503 is fixedly mounted on the outer wall of the fixed post 501. The top of the mounting plate 503 is provided with honeycomb holes 504.

[0026] In the above structure, by setting the buffer component 5, the buffer component 5 is installed on the top and bottom four corners of the power adapter body 1, so that the buffer component 5 will protect the top and bottom four corners of the power adapter body 1 when it is dropped.

[0027] In a preferred embodiment: the telescopic assembly 10 includes a sleeve 1001, the outer wall of the sleeve 1001 is provided with a straight groove 1002, the inner cavity of the sleeve 1001 is provided with a spring 1003, the inner wall of the sleeve 1001 is slidably connected to a connecting rod 1004, the outer wall of the connecting rod 1004 is fixedly fitted with a spring piece 1005, the outer wall of the spring piece 1005 is fixedly installed with a ball 1006, the outer wall of the protective block 2 is fixedly fitted with a sleeve 1007, the outer wall of the sleeve 1007 is provided with a straight groove 1008 and a round hole 1009, and the inner wall of the sleeve 1007 is slidably connected to a sleeve 3 1010.

[0028] In a preferred embodiment: there are several round holes 1009, and the several round holes 1009 are respectively disposed on one side of the outer wall of sleeve 2 1007 and sleeve 3 1010. The diameter of the round hole 1009 is smaller than that of the sphere 1006, and the inner wall of the round hole 1009 is in contact with the inner wall of the sphere 1006.

[0029] In the above structure, by setting the sphere 1006 and the circular hole 1009, the sphere 1006 will move closer to the inner wall of the connecting rod 1004 under the compression of the second spring piece 1005. Then, when the connecting rod 1004 extends into the inner cavity of the sleeve 1010 and releases the sphere 1006, the sphere 1006 will fit into the circular hole 1009, which has a smaller diameter than the sphere 1006, under the compression and rebound of the second spring piece 1005. Then, by the same operation, the sphere 1006 and the circular hole 1009 can be adjusted to adapt to different sizes of power adapter body 1.

[0030] In a preferred embodiment, the number of telescopic components 10 is eight, and the eight telescopic components 10 are respectively arranged on both sides of the outer wall of the protective block 2.

[0031] In the above structure, by setting the telescopic component 10, when the telescopic component 10 is set on both sides of the outer wall of the protective block 2, the length of the telescopic component 10 can be adjusted to adapt to the power adapter body 1 of different shapes.

[0032] In a preferred embodiment: there are eight buffer components 5, eight protective blocks 1, eight protective blocks 2, eight circular grooves 4, eight slots 6, eight springs 1, eight sliding grooves 8, and eight push plates 9 respectively. Each buffer component 5, one protective block 1, one protective block 2, one circular groove 4, one slot 6, one spring 1, one sliding groove 8, and one push plate 9 are arranged as a group on both sides of the outer wall of the power adapter body 1.

[0033] In the above structure, by setting up the buffer component 5, protective block 1 2, protective block 2 3, circular groove 4, slot 6, spring 1 7, slide 8, and push plate 9, when the power adapter body 1 is vibrated or dropped, the eight buffer components 5, protective block 1 2, protective block 2 3, circular groove 4, slot 6, spring 1 7, slide 8, and push plate 9 will provide shock absorption and protection to the four corners of the top and bottom of the power adapter body 1.

[0034] In a preferred embodiment, the shape of the spring piece 502 is the same as that of the slot 6, and the outer wall of the spring piece 502 is adapted to the inner wall of the slot 6.

[0035] In the above structure, by setting the spring piece 502, by pressing the fixing post 501, the outer wall of the spring piece 502 will separate from the inner wall of the slot 6. Then, the outer wall of the spring piece 502 will be compressed after separating from the inner wall of the slot 6, and the compressed spring piece 502 will move closer to the outer wall of the fixing post 501.

[0036] In a preferred embodiment, there are a plurality of honeycomb holes 504, and the honeycomb holes 504 are hexagonal in shape.

[0037] In the above structure, by setting the honeycomb holes 504, each hexagonal honeycomb hole 504 can disperse and dissipate the falling impact force generated by the power adapter body 1 when subjected to external force, thereby effectively absorbing and buffering the impact energy.

[0038] Working principle: When the above device is in use, by installing eight buffer components 5, protective block one 2, protective block two 3, circular groove 4, card slot 6, spring one 7, slide 8, and push plate 9 at each corner of the power adapter body 1, the impact of the power adapter body 1 falling is absorbed by the protective block two 3. However, when absorbing the impact, the protective block two 3 will move closer to the protective block one 2, so that several hexagonal honeycomb holes 504 will be placed near the protective block two 3. When the protective block 1 is near 2, the impact of the fall on the protective block 2 3 is dispersed and dissipated. Simultaneously, when the honeycomb hole 504 needs to be replaced, pressing the fixing post 501 causes the outer wall of the spring piece 1 502 to disengage from the inner wall of the slot 6. After disengaging from the inner wall of the slot 6, the outer wall of the spring piece 1 502 is compressed. Then, after the spring piece 1 502 disengages from the slot 6, the fixing post 501 contacts the push plate 9. As the push plate 9 moves towards the slide groove 8, the spring 1 7 is compressed. Then, by loosening the fixing post 501, the fixing post 501 will pop out of the inner cavity of the circular groove 4 under the compression and rebound of the spring 7, thereby realizing the replacement of the honeycomb hole 504. When the equipment needs to install and fix the buffer assembly 5, protective block 1 2, protective block 2 3, circular groove 4, card slot 6, spring 1 7, slide 8, and push plate 9, by pressing the ball 1006, the ball 1006 will move closer to the inner wall of the connecting rod 1004 under the compression of the spring 2 1005, and then the connecting rod 1004... When the ball 1006 is released when it extends into the inner cavity of the sleeve 3 1010, the ball 1006 will fit into the circular hole 1009 with a diameter smaller than that of the ball 1006 under the compression and rebound of the spring 2 1005. This achieves the fixation of the buffer assembly 5, the protective block 1 2, the protective block 2 3, the circular groove 4, the slot 6, the spring 1 7, the slide 8, and the push plate 9 after installation. Then, the telescopic assembly 10 can also be used to adjust the length and width of the power adapter body 1 through the same operation.
