[0040] A sealing strip is pasted inside the groove 105b. When the cover 102 is closed on the box 101, the protrusion 105a is engaged in the groove 105b, which can enhance the sealing of the connection between the cover 102 and the box 101 and prevent dust or water from entering and damaging the instrument.
[0041] Example 3
[0042] Reference Figures 2-5 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0043] Specifically, the cushioning component 201 includes an inner liner 201a and a storage slot 201b. The inner liner 201a is disposed inside the bottom slot 103a, and the storage slot 201b is opened inside the inner liner 201a. The cushioning component 201 also includes memory foam 201c, which fills the inner cavity of the inner liner 201a. The lifting rope 205 is fixedly connected to one side of the inner liner 201a.
[0044] The inner liner 201a is made of high-density closed-cell foam (such as EVA or polyethylene), which has the advantages of shock absorption, moisture protection, and lightweight. The dimensions of the storage tank 201b are designed according to the actual dimensions of the geophysical instruments to be stored, and are not limited to... Figure 4 The shape of the inner liner 201a is due to the fact that the inner liner 201a is made of a new type of polymer material, polyurethane, which has a stable chemical structure and is not easily deformed or decomposed. It has a low density, is soft, and can recover its original shape after being subjected to force. This allows it to quickly return to its original shape after the inner liner 201a has deformed, preventing damage to the instrument from compression. The inner liner 201a can be quickly removed from the bottom groove 103a using the lifting rope 205, facilitating its replacement and maintenance.
[0045] Specifically, foam pads 202 are fixedly connected to the inner cavities of the bottom groove 103a and the card slot 103b; Velcro 203 is fixedly connected to the bottom of the inner liner 201a and the outer side of the foam pad 202.
[0046] The foam pad 202 can absorb vertical impacts on the housing 101 and the cover 102, improving the protection of the instrument. The bottom of the inner liner 201a and the foam pad 202 inside the bottom groove 103a are fixed with corresponding Velcro 203. The inner liner 201a can be detachably installed in the housing 101 through the Velcro 203, making it easy to replace the inner liner 201a.
[0047] Specifically, the limiting component 204 includes a rubber plate 204a, an airbag strip 204b, a snap fastener 204c, and a storage groove 204d. The rubber plate 204a is disposed inside the cover 102, the airbag strip 204b is installed on the top of the inner liner 201a through the snap fastener 204c, and the storage groove 204d is opened inside the rubber plate 204a.
[0048] The rubber sheet 204a is attached to the foam pad 202 of the slot 103b, and its size is the same as that of the storage slot 201b. The airbag strip 204b has an inflation nozzle. After it is fully inflated, it is snapped onto the inner liner 201a using the snap button 204c (the inner liner 201a has a snap groove corresponding to the snap button). It is tightly attached to the outside of the instrument. When the cover 102 is closed, it is neatly stored in the storage slot 204d. The rubber sheet 204a and the airbag strip 204b are used to firmly snap the instrument into the storage slot 201b, preventing the instrument from shaking due to gaps between it and the case 101 and the cover 102 (the rubber sheet 204a can be stored in the storage slot 201b without affecting the closing of the cover 102).
[0049] When in use, store the instrument in the storage slot 201b of the inner liner 201a, and then close the cover 102 to seal and protect the instrument. The inner liner 201a is made of high-density closed-cell foam (such as EVA or polyethylene), which has the advantages of shock absorption, moisture protection and lightweight. The internal memory pearl cotton 201c is a new type of polymer material made of polyurethane, which has a stable chemical structure and is not easy to deform or decompose. Its low density and softness allow it to recover its original shape after being subjected to force. It can quickly return to its original shape after the inner liner 201a is deformed, avoiding damage to the instrument from compression. The foam pad 202 can absorb vertical impacts on the housing 101 and the cover 102, improving the protection of the instrument. It is installed on the inner liner 201a by snapping on the snap 204c, and is close to the outside of the instrument. When the cover 102 is closed, it is stored in the storage slot 204d. The rubber plate 204a and the air bag strip 204b are used to firmly attach the instrument to the storage slot 201b, preventing the instrument from shaking due to gaps between it and the housing 101 and the cover 102.
