[0052] In the embodiment, the outer baffle 13 is integrally formed with the support 1, and the inner baffle 36 is integrally formed with the cover plate 2, and the number of the inner baffles 36 is the same as that of the outer baffles 13.

[0053] The surface of the cover plate 2 and the bottom surface of the support 1 are provided with corresponding mounting grooves, and the whole door opening device is mounted in the drawer seat through the mounting grooves.

[0054] A pair of working guide strips 35 are arranged on the surface of the top plate 3, the working guide strips 35 are in a "Z" shape structure, the working guide strips 35 are matched with the clamping holes on the insulation partition plate 62, and when the top plate 3 moves forward and backward, the working guide strips 35 are matched with the insulation partition plate 62 to drive the insulation partition plate 62 to move on the drawer seat.

[0055] The drawer seat insulation partition plate door opening device, when working, the top plate 3 is pressed to drive the top plate 3 to move forward and backward, the top plate 3 is guided to stably translate by the internal positioning block 32, and when the positioning block 32 moves to the bottom, the top plate 3 reaches the specified working position, at this time, the compression spring 5 is compressed, and when the pressure of the top plate 3 disappears, the top plate 3 moves outward under the energy release of the compression spring 5, until the inner baffle 36 abuts against the outer baffle 13, and the top plate 3 returns to the initial position.

[0056] As shown in Figure 8 and Figure 9 The drawer seat includes a base 61, a pair of insulation partition plates 62 and a door opening device, and the insulation partition plate 62 is provided with a plug hole 63, when the two insulation partition plates 62 are translated to be opposite to each other, at this time, the body female row can be inserted through the plug hole 63, when the two insulation partition plates 62 are staggered, the plug hole 63 on each of the two insulation partition plates 62 is blocked by the other partition plate, at this time, the body female row cannot be inserted.

[0057] The door opening device of the embodiment, by increasing the positioning block 32 at the rear end of the top plate 3, the movement of the top plate 3 in the front and rear directions in the support 1 is more stable, the top plate 3 is not easy to shake in the left and right directions and the up and down directions, the top plate 3 stably stretches and retracts, and it is ensured that the insulation partition plate 62 can be stably translated, and the insulation partition plate 62 is smooth, stable and reliable when opening and closing the door.
