DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1

[0027] See also Figure 1-Figure 4 , a PVC environmentally friendly heat stabilizer moisture-proof storage device shown in the figure comprises a box body 1, a multi-layer moisture-proof drawer 2 and a storage drawer 3 are installed on the box body 1, and a handle 4 is provided on the moisture-proof drawer 2 and the storage drawer 3. The moisture-proof drawer 2 is installed in a moisture-proof layer 11 in the box body 1, and the storage drawer 3 is installed in a storage layer 12 in the box body 1. The moisture-proof layer 11 and the storage layer 12 are connected through a through hole;

[0028] The size of the moisture-proof drawer 2 is adapted to the moisture-proof layer 11. A mesh plate 21 is provided at the bottom of the moisture-proof drawer 2. Limiting holes 22 are provided on both sides of the moisture-proof drawer 2. Connecting holes are provided on both sides of the inner wall of the moisture-proof layer 11. A spring 111 is installed in the connecting hole of the moisture-proof layer 11. The spring 111 is connected to the limiting block 112, and the limiting block 112 corresponds to the limiting hole 22.

[0029] In this solution, the storage drawer 3 is used to store the PVC environmentally friendly heat stabilizer, and a large amount of desiccant is stored in the moisture-proof drawer 2. The moisture-proof drawer 2 is arranged above the storage drawer 3, so that the moisture inside the storage drawer 3 enters the moisture-proof layer 11 through the through hole between the moisture-proof layer 11 and the storage layer 12, and enters the moisture-proof drawer 2 through the mesh plate 21 arranged at the bottom of the moisture-proof drawer 2, and the desiccant in the moisture-proof drawer 2 is used to absorb moisture, thereby ensuring the drying of the PVC environmentally friendly heat stabilizer in the storage drawer 3;

[0030] When the desiccant in the moisture-proof drawer 2 absorbs a large amount of moisture, the moisture-proof drawer 2 is taken out of the moisture-proof layer 11 by using the handle 4, the wet desiccant is taken out and the mesh plate 21 is cleaned to prevent the wet desiccant from clogging the mesh plate 21 and realize the convenient replacement of the desiccant. Then, a new desiccant is replaced to ensure the subsequent moisture absorption effect. The replaced moisture-proof drawer 2 is reinstalled into the moisture-proof layer 11. During this process, the moisture-proof drawer 2 squeezes the limit block 112 so that the limit block 112 squeezes the spring 111 and retracts into the connecting hole. When the limit hole 22 corresponds to the limit block 112, the spring 111 returns to its original state and pushes the limit block 112 into the limit hole 22, thereby realizing the limit fixation of the moisture-proof drawer 2, and preventing the moisture-proof drawer 2 from shaking and creating a gap with the box body 1, causing external moisture to enter the moisture-proof drawer 2, affecting the absorption of moisture in the storage drawer 3 by the desiccant in the moisture-proof drawer 2.

[0031] For further information, see Figure 5-Figure 10, both sides of the storage drawer 3 are provided with limiting grooves 31, and the bottoms of both sides of the storage layer 12 are provided with notches 121, and fixed blocks 123 are installed in the notches 121, and connecting rods 124 and 125 are fixedly installed on the fixed blocks 123, and the connecting rods 124 and 125 are installed in the slides 122, and the slides 122 are arranged on the top of the notches 121;

[0032] The inner walls of both sides of the storage layer 12 are provided with moving grooves 13, one end of the moving groove 13 is provided with a spring groove 14, a spring 15 is installed in the spring groove 14, a push plate 5 is movably connected in the storage layer 12, both ends of the push plate 5 are fixed with moving plates 51, the moving plate 51 is installed in the moving groove 13, a connecting column 511 is provided on the moving plate 51, and the connecting column 511 is connected to one end of the spring 15;

[0033] A plurality of springs 3 52 are fixed to one side of the push plate 5, and the push plate 5 is connected to the inner wall of the storage layer 12 through the springs 3 52;

[0034] The movable plate 51 is provided with a slide groove 53, which includes a branch groove 1 531, one end of which is connected to the branch groove 2 532, one end of which is connected to one end of the branch groove 3 533 through the branch groove 2 532, and the other end of the branch groove 3 533 is connected to the branch groove 1 531, and an elbow connecting rod 131 is slidably connected in the slide groove 53, and one end of the elbow connecting rod 131 is rotatably connected to the movable groove 13;

[0035] Specifically, the connecting rod 124 is rotatably connected to the bottom of the movable plate 51. When the storage drawer 3 is installed in the storage layer 12, the storage drawer 3 is pushed and the push plate 5 is pushed, so that the push plate 5 squeezes the spring 3 52. At the same time, the movable plate 51 moves in the movable groove 13, driving the spring 2 15 to stretch, so that one end of the elbow of the elbow connecting rod 131 in the movable groove 13 moves in the slide groove 53, and the other end of the branch groove 3 533 is connected to the branch groove 1 531. At the same time, the width of the other end of the branch groove 3 533 is greater than the width of the branch groove 1 531, so that when the elbow connecting rod 131 moves, it first moves along the branch groove 1 531 and enters the branch groove 2 532. Under the action of the third spring 52, the elbow of one end of the elbow connecting rod 131 is stuck in the groove of the second branch groove 532. At this time, the movable plate 51 drives the fixed block 123 to move along the slide 122 through the connecting rod 124. The movement of the connecting rod 124 and the second connecting rod 125 in the slide 122 makes the fixed block 123 parallel to the storage drawer 3, so that the protrusion on the fixed block 123 enters the limiting groove 31, so as to limit the storage drawer 3 and prevent the storage drawer 3 from detaching from the storage layer 12 when it is shaken by external force, so as to prevent the storage drawer 3 from generating a gap between the storage drawer 3 and the box body 1, thereby affecting the absorption of moisture in the storage drawer 3 by the desiccant in the moisture-proof drawer 2;

[0036] When the storage drawer 3 needs to be taken out, the storage drawer 3 is pushed so that it pushes the push plate 5 to squeeze the spring three 52, and at the same time, the movable plate 51 moves in the movable groove 13, so that the elbow at one end of the elbow connecting rod 131 moves out of the groove of the branch groove two 532, and the width of one end of the branch groove one 531 is greater than the width of the branch groove two 532, so that the elbow at one end of the elbow connecting rod 131 enters into the branch groove three 533 along the branch groove two 532, and enters into the branch groove one 531 along the branch groove three 533, so that the restriction of the elbow connecting rod 131 on the movable plate 51 is reduced, so that it moves toward the outside of the box body 1 under the drive of the spring two 15 and the spring three 52, so that the movable plate 51 drives the fixed block 123 to move along the slide 122 through the connecting rod one 124, so that the fixed block 123 retracts into the notch 121, thereby avoiding limiting the storage drawer 3 and facilitating the storage drawer 3 to be taken out from the storage layer 12.
