[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figures 1 to 5This utility model discloses a foam liner for electrical appliance packaging, comprising a lower liner 1, an upper liner 2 above the lower liner 1, and an installation groove formed on the top surface of the lower liner 1 and the bottom surface of the upper liner 2. A positioning and sealing component is installed on the bottom surface of the upper liner 2 to prevent external moisture and other impurities from entering and affecting the quality of the internal electrical appliances. Positioning grooves are formed at the four corners of the lower liner 1, and two sealing grooves are formed around the top surface of the lower liner 1. Slots are formed on both sides of the top surface of the lower liner 1. The slot is placed inside the sealing groove of the inner ring. The front sides of the lower liner 1 are respectively provided with a support groove and a protection groove. The lower liner 1 and the upper liner 2 are respectively provided with a limiting groove in the middle of their front ends. The positioning block 3 facilitates the quick positioning and connection of the upper liner 2 and the lower liner 1. Positioning blocks 3 are installed at the four corners of the bottom surface of the upper liner 2. The cross-section of the positioning block 3 is L-shaped. The two sides of the bottom surface of the upper liner 2 are respectively provided with buckles 5. The buckles 5 cooperate with the slot. The buckles 5 facilitate the connection and fixation of the upper liner 2 and the lower liner 1.

[0015] In this utility model, the sealing assembly includes two sealing rings 6 installed on the periphery of the bottom surface of the upper gasket 2. The lower end of the sealing ring 6 cooperates with the sealing groove, and the sealing ring 6 facilitates the prevention of moisture from entering the interior. The interior of the support groove is connected to two return springs 8. A return plate 7 is provided above the return springs 8. The two ends of the return springs 8 are respectively connected to the lower gasket 1 and the return plate 7, and the return springs 8 facilitate the control of the ejection of objects in the support groove. The upper part of the support groove and the protective groove are respectively provided with a limiting block 4 and a protective block. The limiting block 4 cooperates with the support groove, and the protective block cooperates with the protective groove, and the limiting block 4 and the protective block facilitate the protection of electrical components.

[0016] Working Principle: In use of this invention, the main electrical component is first placed in the mounting groove formed by the mating of the top surface of the lower pad 1 and the bottom surface of the upper pad 2. Then, other parts required for assembling the electrical component are placed in the support grooves and protective grooves on both sides of the front end of the lower pad 1, as well as the limiting groove formed by the mating of the lower pad 1 and the middle of the front end of the upper pad 2. Subsequently, the upper pad 2 and the lower pad 1 are assembled. First, the L-shaped positioning blocks 3 installed at the four corners of the bottom surface of the upper pad 2 engage with the positioning grooves at the four corners of the lower pad 1, quickly inserting the upper pad 2 into the corresponding position of the lower pad 1, achieving initial positioning and connection. During this process, the two sealing rings 6 installed on the periphery of the bottom surface of the upper pad 2 simultaneously engage with the two sealing grooves on the periphery of the top surface of the lower pad 1. The tight fit between the sealing rings 6 and the sealing grooves effectively prevents external moisture and other impurities from entering the pads. To prevent any impact on the quality of the internal electrical components, the upper pad 2 has clips 5 installed on both sides of its bottom surface. These clips engage with the slots on both sides of the top surface of the lower pad 1, securing the lower pad 1 and the upper pad 2 together and preventing them from becoming loose during subsequent handling. Furthermore, the limiting blocks 4 on the upper pad 2 corresponding to the support grooves compress the parts placed within the support grooves, thus providing shock absorption and protection. The protective blocks on the upper pad 2 corresponding to the protective grooves also cooperate with the protective grooves to protect the parts placed within them. The two return springs 8 connected inside the support grooves (with their ends connected to the lower pad 1 and the upper return plate 7, respectively) facilitate the control of objects ejecting when removing parts from the support grooves. Once all the above assembly and protection steps are completed, the packaging of the electrical appliances is finished.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
