Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-4 A solid waste sample sampling and retention device includes an outer sleeve 1, a shock-absorbing layer 2, and an inner sleeve 3 arranged in sequence from the outside to the inside. The side wall of the outer sleeve 1 is provided with an observation port 11. A positioning ring 12 is fixedly connected to the inner side of the port of the outer sleeve 1. The shock-absorbing layer 2 is arranged below the positioning ring 12 and keeps in contact with the positioning ring 12. A pressure ring 31 arranged above the positioning ring 12 is fixedly connected to the outer side of the port of the inner sleeve 3. A shock-absorbing rubber ring 61 is provided between the pressure ring 31 and the positioning ring 12.

[0033] The assembly cover 4 and the sealing plug 5 are screwed together. The sealing plug 5 is rotatably mounted on the assembly cover 4 and sealed and plugged with the opening end of the inner sleeve 3 .

[0034] A backing plate 41 is fixed to the inner side of the assembly cover 4, and a rotating seat 51 rotatably connected to the backing plate 41 is fixed to the sealing plug 5. A connecting seat 52 arranged above the backing plate 41 is fixed to the rotating seat 51, and a connecting sleeve 53 that is kept in contact with the backing plate 41 is screwed to the connecting seat 52.

[0035] The outer sleeve 1 and the assembly cover 4 can provide effective protection and support, thereby ensuring the storage stability of the inner sleeve 3 and the solid waste samples stored therein.

[0036] The sealing plug 5 is combined with the assembly cover 4 through the rotating seat 51 thereon, and is installed on the assembly cover 4 by screwing the combined connecting seat 52 and connecting sleeve 53, so that the sealing plug 5 can be rotatably installed in the assembly cover 4.

[0037] After the assembly cover 4 and the outer sleeve 1 are fixedly combined by screwing, a stable external support structure is formed to protect the inner sleeve 3 and the solid sample. At the same time, the sealing plug 5 can be sealed and plugged into the inner sleeve 3 to prevent the volatilization and leakage of toxic and harmful substances contained in the solid waste, thereby ensuring the long-term stability of the solid waste.

[0038] The shock-absorbing layer 2 is arranged between the outer sleeve 1 and the inner sleeve 3 , and can improve the stable buffering and shock-absorbing effects to effectively protect the inner sleeve 3 .

[0039] In order to ensure that the outer sleeve 1, the shock-absorbing layer 2, and the inner sleeve 3 can play their designed roles and the state of the solid waste in the inner sleeve 3 can be checked through the observation port 11, the following technical solution is provided.

[0040] The outer sleeve 1 is made of stainless steel, the shock-absorbing layer 2 is made of transparent silicone, and the inner sleeve 3 is made of glass.

[0041] The outer sleeve 1, made of stainless steel, has excellent structural strength, preventing damage to the sampling and retention device due to pressure. The shock-absorbing layer 2, made of transparent silicone, not only has a good shock-absorbing effect, preventing rigid contact between the outer sleeve 1 and the inner sleeve 3, but also acts as a shock-absorbing buffer to prevent damage to the glass inner sleeve 3 due to vibration. The transparent silicone also ensures that the solid waste sample in the inner sleeve 3 passes through the glass layer, transparent silicone, and observation port 11, facilitating observation of the status of the solid waste. The inner sleeve 3, made of glass, has excellent corrosion resistance, preventing the solid waste sample from reacting with the container.

[0042] In order to ensure that the sealing plug 5 can achieve a sealing effect at the connection position between the two after being combined with the inner sleeve 3, the following technical solution is provided.

[0043] The sealing plug 5 is fixedly connected to a pressure plate 54 arranged above the pressure ring 31. The pressure plate 54 is arranged between the rotating seat 51 and the sealing plug 5. The pressure plate 54 and the pressure ring 31 bracket are provided with a sealing rubber ring 62. Multiple sets of sealing rings 63 are nested and installed on the sealing plug 5. The sealing rings 63 maintain a sealed fit with the inner sleeve 3.

[0044] The pressure plate 54 is sealed against the top pressure ring 31 of the inner sleeve 3 via the sealing rubber ring 62 , which ensures a sealed connection between the sealing plug 5 and the inner sleeve 3 while avoiding direct rigid contact between the pressure plate 54 and the pressure ring 31 .

[0045] The provision of the multi-layer sealing ring 63 can form a multi-layer sealing structure between the sealing plug 5 and the inner sleeve 3 to ensure an airtight effect.

[0046] In order to ensure that the assembly cover 4 can be screwed and fixed to the outer sleeve 1 and that the sealing plug 5 can be installed in the assembly cover 4 in a relatively rotatable manner, the following technical solution is provided.

[0047] The outer side of the port of the outer sleeve 1 is fixed with a limit ring 13. The outer wall of the outer sleeve 1 is provided with an external thread A14 arranged above the limit ring 13. The inner wall of the assembly cover 4 is provided with an internal thread A42 arranged below the pad 41 and adapted to the external thread A14.

[0048] The diameter of the connecting seat 52 is smaller than that of the rotating seat 51 , and an external thread B55 is provided on the outer wall of the connecting seat 52 . The outer diameter of the connecting sleeve 53 is larger than the diameter of the rotating seat 51 , and an internal thread B56 is provided on the inner wall of the connecting sleeve 53 that matches the external thread B55 .

[0049] After the assembly cover 4 is screwed into place, it abuts against the limiting ring 13 below, which can prevent the external thread A14 and the internal thread A42 from being stripped and affecting the stability of the assembly connection.

[0050] After the connecting sleeve 53 is screwed together with the connecting seat 52, it can limit the sealing plug 5 as a whole, so that it can be stably installed in the assembly cover 4 in a relatively rotating manner. During the assembly of the assembly cover 4 and the outer sleeve 1, the sealing plug 5 and the inner sleeve 3 can be sealed and plugged together.

[0051] In order to hide the connecting sleeve 53 extending into the pad 41 and prevent dust from invading and affecting the assembly effect of the assembly cover 4 and the sealing plug 5, a nested ring groove 43 is opened on the top of the assembly cover 4, and a pressure cover 44 is nested in the nested ring groove 43.

[0052] The pressure cover 44 is assembled to the top of the assembly cover 4 in a nested manner, which is convenient for disassembly to carry out the installation and removal operation of the sealing plug 5. At the same time, the pressure cover 44 can seal the top of the assembly cover 4 to prevent dust from entering.
