The first positioning mechanism 7, the second positioning mechanism 8, the third positioning mechanism 9, the fourth positioning mechanism 10, the fifth positioning mechanism 11 and the sixth positioning mechanism 12 are designed to avoid drawing out the partition board 6 from the fresh-keeping chamber 2 and then placing the partition board 6 at the next layer or the previous layer when the partition board 6 in the fresh-keeping chamber 2 needs to be adjusted up and down; the purpose of moving the clapboard 6 can be achieved only by directly moving the clapboard 6 up and down by holding the clapboard 6 by hand.

The first square groove 16 of the present invention is designed to provide sufficient space for the movement of the plate spring 32.

In the invention, the first one-way clutch 19 only acts when the swing block 20 swings downwards, and when the swing block 20 swings upwards, the first one-way clutch 19 does not act on the swing block 20.

The design purpose of the invention that the connection point of the plate spring 32 and the first air pressure shell 26 is located at the edge of the end face of the first air pressure shell 26, and the connection point of the plate spring 32 and the second shaft 42 is located at the edge of the end face of the second shaft 42 is that the plate spring 32 is properly deformed under the drive of the second shaft 42 and does not cause excessive deformation damage to the plate spring 32.

The plate spring 32 of the present invention is deformed when the latch 52 swings from the vertical position to the horizontal position, and the plate spring 32 is restored to its shape when the latch 52 swings from the horizontal position to the vertical position.

The purpose of the present invention is that the air inlet holes 39 on the second air pressure shell 33 are communicated with the corresponding air outlet holes 28 on the first air pressure shell 26 through thin pipes, so that the speed of the gas compressed in the first air pressure shell 26 entering the second air pressure shell 33 is reduced; if the partition 6 is initially positioned above the first positioning means 7 and the second positioning means 8; when the partition plate 6 in the fresh-keeping chamber 2 of the refrigerator needs to move from the layer to the fifth positioning mechanism 11 and the sixth positioning mechanism 12 below, the partition plate 6 is lifted by hands to move upwards for a certain distance, and then the air vents 36 in the first positioning mechanism 7 and the second positioning mechanism 8 connect the second air pressure cavity 34 with the outside atmosphere; the first air pressure chamber 27 and the second air pressure chamber 34 in the first positioning mechanism 7 and the second positioning mechanism 8 are no longer closed spaces, and the two swing blocks 20 of the first positioning mechanism 7 and the second positioning mechanism 8 simultaneously swing upwards to return to the horizontal position under the action of the first scroll spring 53 and the first one-way clutch 19; because the plate spring 32 has a certain torque to the second shaft 42, the four clamping wheels 50 in the first positioning mechanism 7 and the second positioning mechanism 8 drive the corresponding clamping blocks 52 to swing upwards to the vertical direction; then the hand supports the clapboard 6 to move downwards to pass through the first positioning mechanism 7 and the second positioning mechanism 8 and move to the third positioning mechanism 9 and the fourth positioning mechanism 10; when two sides of the partition plate 6 simultaneously touch two swing blocks 20 in the third positioning mechanism 9 and the fourth positioning mechanism 10, the two swing blocks 20 swing downwards, and the two swing blocks 20 drive the pressing block 25 to move through the corresponding first one-way clutch 19, the first shaft 21 and the shaft sleeve 22; the pressing blocks 25 in the two first air pressure cavities 27 of the third positioning mechanism 9 compress the air and make it form high pressure; the high-pressure gas in the two first air pressure cavities 27 enters the two second air pressure cavities 34 through the corresponding gas outlet holes 28 and gas inlet holes 39 respectively; the air entering the second air pressure chamber 34 presses the corresponding arc-shaped block 45 to drive the second shaft 42 to rotate around the central axis of the second shaft 42; the second shaft 42 drives the clamping block 52 to swing towards the partition board 6 through the clamping wheel 50; since the air inlet holes 39 on the second air pressure shell 33 in the third positioning mechanism 9 are communicated with the corresponding air outlet holes 28 on the first air pressure shell 26 through thin pipes, the speed of high-pressure air entering the second air pressure cavity 34 from the first air pressure cavity 27 lags behind by three to four seconds; the pressing blocks 25 in the two first air pressure cavities 27 of the fourth positioning mechanism 10 compress the air and make the air form high pressure; the high-pressure gas in the two first air pressure cavities 27 enters the two second air pressure cavities 34 through the corresponding gas outlet holes 28 and gas inlet holes 39 respectively; the air entering the second air pressure chamber 34 presses the corresponding arc-shaped block 45 to drive the second shaft 42 to rotate around the central axis of the second shaft 42; the second shaft 42 drives the clamping block 52 to swing towards the partition board 6 through the clamping wheel 50; since the air inlet holes 39 on the second air pressure housing 33 in the fourth positioning mechanism 10 are communicated with the corresponding air outlet holes 28 on the first air pressure housing 26 through thin tubes, the speed of the high-pressure air entering the second air pressure chamber 34 from the first air pressure chamber 27 lags behind by three to four seconds; the partition board 6 continues to move downwards and drives the swing block 20 to continue to swing downwards, and when the fixture blocks 52 in the third positioning mechanism 9 and the fourth positioning mechanism 10 are not swung out of the corresponding second square holes 54, the partition board 6 passes through the layer where the third positioning mechanism 9 and the fourth positioning mechanism 10 are located; after the partition board 6 passes through the layer where the third positioning mechanism 9 and the fourth positioning mechanism 10 are located, the partition board 6 passes through the two swing blocks 20 on the third positioning mechanism 9 and the fourth positioning mechanism 10; the arc blocks 45 in the third positioning mechanism 9 and the fourth positioning mechanism 10 swing for 180 degrees under the action of high-pressure gas and the plate spring 32; the two swing blocks 20 swing back to the horizontal position under the action of the first scroll spring 53 and the first one-way clutch 19; when the partition board 6 moves to the layer where the fifth positioning mechanism 11 and the sixth positioning mechanism 12 are located, the partition board 6 acts on the two swinging blocks 20, so that the swinging blocks 20 swing from the horizontal position to the position where the partition board 6 is fixed; since the air inlet holes 39 on the second air pressure shell 33 are communicated with the corresponding air outlet holes 28 on the first air pressure shell 26 through thin pipes, so that the speed of high-pressure air entering the second air pressure cavity 34 from the first air pressure cavity 27 lags behind by three to four seconds, the hand holds the clapboard 6 for three to four seconds, the clamping blocks 52 of the third positioning mechanism 9 and the fourth positioning mechanism 10 swing to the horizontal position to hold the clapboard 6, and then the hand is released, and the clapboard 6 is fixed.

The radian of the arc-shaped groove 35 is 180 degrees, and the radian of the arc-shaped surface of the sealing block 40 is 91 degrees, so that by taking the third positioning mechanism 9 and the fourth positioning mechanism 10 on the same layer as an example, when no partition plate 6 is arranged on the third positioning mechanism 9 and the fourth positioning mechanism 10, the clamping block 52 is in a vertical position, and the swinging block 20 is in a horizontal position; when the partition plate 6 needs to be placed on the layer where the third positioning mechanism 9 and the fourth positioning mechanism 10 are located from top to bottom, the partition plate 6 firstly acts on the swing block 20 and enables the swing block 20 to swing downwards; the swing block 20 drives the pressing block 25 to swing around the central axis of the first shaft 21 through the first one-way clutch 19, the first shaft 21 and the shaft sleeve 22; at the same time, first scroll spring 53 is deformed; the pressing block 25 compresses the air in the first air pressure cavity 27 to form high pressure; high-pressure gas enters the second pneumatic cavity 34 through the gas outlet hole 28 and the gas inlet hole 39; because the space is sealed when the arc block 45 and the sealing block 40 are arranged; the high-pressure gas entering the arc-shaped block 45 drives the arc-shaped block to swing for exactly 91 degrees around the central axis of the second shaft 42; the arc-shaped block 45 drives the second shaft 42 to rotate; the second shaft 42 deforms the leaf spring 32 connected thereto; the connecting point of the second shaft 42 and the plate spring 32 swings by 91 degrees from the position of the horizontal radius, and the plate spring 32 slightly deviates from the vertical radius of the second shaft 42 to generate certain torque on the second shaft 42; at this time, the closed space formed by the arc block end face 49 and the sealing block 40 is about to communicate with the arc groove 35 but not communicated with the same; after the partition plate 6 swings at a certain angle along with the swing block 20, the hand supports the partition plate 6 and stays for three to four seconds, the fixture block 52 swings to the horizontal position from the original vertical position, and the fixture block 52 swinging to the horizontal position meets the partition plate 6; the fixture block 52 lifts the partition plate 6 under the action of high-pressure gas in the second air pressure cavity 34; the partition 6 is fixed on the layer where the first positioning mechanism 7 and the second positioning mechanism 8 are located; when the clapboard 6 needs to be moved from one layer to another layer, the hand supports the clapboard 6 to move upwards for a certain distance, and the clapboard 6 is contacted with the pressure on the clamping block 52; because the plate spring 32 has a certain torque to the second shaft 42, the plate spring 32 enables the second shaft 42 to drive the fixture block 52 to swing upwards through the fixture wheel 50 and the second shaft 42; the second shaft 42 drives the arc-shaped block 45 to swing; the space formed by the arc block end surface 49 and the sealing block 40 is communicated with the arc groove 35; the other end of the arc-shaped groove 35 is communicated with the atmosphere through an air vent 36; two cavities formed by the arc-shaped block 45 and the sealing block 40 in the second air pressure cavity 34 are communicated with the outside atmosphere; under the restoring force of the first scroll spring 53, the first shaft 21, the first one-way clutch 19 and the driving ring 18 are made to swing the swing block 20 back to the horizontal position; at the moment, the deformation amount of the plate spring 32 just enables the second shaft 42 to drive the arc-shaped block 45 to swing for 89 degrees; so that the arc-shaped block 45 just covers the air vent hole 36, and the fixture block 52 swings upwards from the horizontal position to the vertical position; in the device, the fixture block 52 swings from the vertical position to the horizontal position, and the amount of high-pressure gas entering the second gas pressure cavity 34 from the first gas pressure cavity 27 just swings the arc-shaped block 45 by 91 degrees; the latch 52 swings from the horizontal position to the vertical position, and the restoring force of the plate spring 32 just swings the arc-shaped block 45 by 89 degrees.

The second one-way clutch 65 of the present invention is designed such that, if the second one-way clutch 65 is not provided, the high pressure gas in the second pneumatic chamber 34 is not sufficient to support the weight of the partition 6 and the articles on the partition 6 when the partition 6 is placed on the latch 52; the weight of the partition 6 and the articles on the partition 6 can make the fixture block 52 swing downwards to drive the arc-shaped block 45 to further compress the air in the second air pressure cavity 34; so that the function of fixing the partition 6 cannot be achieved; the second one-way clutch 65 is used to prevent the latch 52 from swinging downward under the gravity of the partition 6 and the articles thereon, so as to prevent the partition 6 from slipping off the latch 52 without being fixed.

The specific implementation mode is as follows: when the partition board 6 needs to move from the layer where the first positioning mechanism 7 and the second positioning mechanism 8 are located to the layer where the third positioning mechanism 9 and the fourth positioning mechanism 10 are located, the partition board 6 is supported by hands to move upwards for a certain distance; the clamping blocks 52 in the first positioning mechanism 7 and the second positioning mechanism 8 are not limited by the partition plate 6 any more; the latch 52 swings upward under the dual action of the high-pressure gas and the plate spring 32; the arc blocks 45 in the first positioning mechanism 7 and the second positioning mechanism 8 no longer cover one end of the arc groove 35; the second pneumatic chamber 34 is open to the atmosphere; under the action of the first scroll spring 53, the first shaft 21 drives the pressing block 25 and the first one-way clutch 19 to swing; a part of the space in the first air pressure chamber 27 communicated with the air outlet hole 28 is increased; air enters the first air pressure cavity 27 from the outside through the air vent hole 36, the arc-shaped groove 35 and the air inlet hole 39; the first one-way clutch 19 drives the swinging block 20 to swing upwards to a horizontal position through the driving ring 18; the clamping block 52 swings from the horizontal position to the vertical position under the continuous action of the plate spring 32, and then the plate spring 32 restores to the original state; meanwhile, the arc-shaped block 45 rotates for 89 degrees to cover the air release hole 36, and the space in the second air pressure cavity 34 communicated with the air inlet hole 39 is closed again; then, the hand supports the clapboard 6 to move downwards, and the clapboard 6 meets the swinging block 20 in the first positioning mechanism 7 and the second positioning mechanism 8 again; the swing block 20 swings downwards, and the swing block 20 drives the pressing block 25 to swing towards the stop block 31 through the driving ring 18, the first one-way clutch 19 and the first shaft 21 and compress air; compressed air enters the second pneumatic chamber 34 through the outlet aperture 28 and the inlet aperture 39; because the air outlet hole 28 is connected with the air inlet hole 39 through a thin pipe, the speed of the compressed air entering the second air pressure cavity 34 through the air outlet hole 28 and the air inlet hole 39 is reduced; the partition board 6 continues to move downwards and passes through the layer where the first positioning mechanism 7 and the second positioning mechanism 8 are located; then high-pressure air from the first air pressure cavity 27 of the first positioning mechanism 7 and the second positioning mechanism 8 is gathered in the second air pressure cavity 34, so that the arc-shaped block 45 swings around the central axis of the second shaft 42; the amount of high pressure air entering the second pneumatic chamber 34 from the first pneumatic chamber 27 just swings the arc-shaped block 45 by 91 degrees; the second shaft 42 drives the fixture block 52 to swing 91 degrees through the fixture wheel 50, so that the fixture block 52 is located at a horizontal position; the plate spring 32 deforms with the rotation of the second shaft 42 and generates a certain torque to the second shaft 42; the torsion of the plate spring 32 on the second shaft 42 enables the arc-shaped block 45 to swing and not to cover the air vent 36 any more, and the second air pressure cavity 34 is communicated with the external atmosphere through the air vent 36 and the arc-shaped groove 35; under the action of the first scroll spring 53, the first shaft 21 drives the pressing block 25 and the first one-way clutch 19 to swing; a part of the space in the first air pressure chamber 27 communicated with the air outlet hole 28 is increased; air enters the first air pressure cavity 27 from the outside through the air vent hole 36, the arc-shaped groove 35 and the air inlet hole 39; the first one-way clutch 19 drives the swinging block 20 to swing upwards to a horizontal position through the driving ring 18; the clamping block 52 swings from the horizontal position to the vertical position under the continuous action of the plate spring 32, and then the plate spring 32 restores to the original state; meanwhile, the arc-shaped block 45 rotates for 89 degrees to cover the air release hole 36, and the space in the second air pressure cavity 34 communicated with the air inlet hole 39 is closed again; when the partition board 6 continues to move downwards to the layer where the third positioning mechanism 9 and the fourth positioning mechanism 10 are located, the swinging blocks 20 in the third positioning mechanism 9 and the fourth positioning mechanism 10 swing downwards under the action of the partition board 6; as the partition plate 6 moves from top to bottom to the layer where the first positioning mechanism 7 and the second positioning mechanism 8 are located, the swing block 20 drives the compression block 25 through the driving ring 18, the first one-way clutch 19 and the first shaft 21 to compress air, so that the air enters the second air pressure cavity 34 from the first air pressure cavity 27 through the air outlet hole 28 and the air inlet hole 39; the arc blocks 45 in the third positioning mechanism 9 and the fourth positioning mechanism 10 swing under the action of high-pressure gas, the second shaft 42 is driven to rotate by the arc blocks 45, and meanwhile, the plate spring 32 deforms along with the rotation of the second shaft 42; since the air inlet holes 39 are connected with the air outlet holes 28 by the thin tube, the speed of the high-pressure air entering the second air pressure cavity 34 from the first air pressure cavity 27 is reduced; the time of the arc-shaped block 45 driving the fixture block 52 to rotate from the vertical position to the horizontal position through the second shaft 42 and the fixture wheel 50 lags behind the time of the partition board 6 reaching the layer by three to four seconds; when the hand supports the partition board 6 to reach the layer, the fixture block 52 of the layer swings to the horizontal position after the hand stays for three to four seconds; under the action of the high-pressure air on the arc-shaped block 45, the fixture block 52 lifts the partition board 6, and the partition board 6 is fixed on the layer where the third positioning mechanism 9 and the fourth positioning mechanism 10 are located; the partition 6 ends the moving process from the upper layer to the lower layer.

When the partition board 6 needs to move to the layer where the first positioning mechanism 7 and the second positioning mechanism 8 are located from the layer where the third positioning mechanism 9 and the fourth positioning mechanism 10 are located, the partition board 6 is supported by hands to move upwards for a certain distance; the clamping blocks 52 in the third positioning mechanism 9 and the fourth positioning mechanism 10 are not limited by the partition plate 6 any more; the latch 52 swings upward under the dual action of the high-pressure gas and the plate spring 32; the arc blocks 45 in the third positioning mechanism 9 and the fourth positioning mechanism 10 no longer cover one end of the arc groove 35; the second pneumatic chamber 34 is open to the atmosphere; under the action of the first scroll spring 53, the first shaft 21 drives the pressing block 25 and the first one-way clutch 19 to swing; a part of the space in the first air pressure chamber 27 communicated with the air outlet hole 28 is increased; air enters the first air pressure cavity 27 from the outside through the air vent hole 36, the arc-shaped groove 35 and the air inlet hole 39; the first one-way clutch 19 drives the swinging block 20 to swing upwards to a horizontal position through the driving ring 18; the clamping block 52 swings from the horizontal position to the vertical position under the continuous action of the plate spring 32, and then the plate spring 32 restores to the original state; meanwhile, the arc-shaped block 45 rotates for 89 degrees to cover the air release hole 36, and the space in the second air pressure cavity 34 communicated with the air inlet hole 39 is closed again; when the partition plate 6 is held by hand and continues to move upwards to the layer where the first positioning mechanism 7 and the second positioning mechanism 8 are located, the partition plate 6 meets the swinging block 20 in the horizontal position; the partition plate 6 continues to move upwards, the swing block 20 swings upwards by the partition plate 6, and the second scroll spring 58 deforms; at this time, the first one-way clutch 19 does not act on the drive ring 18; partition 6 continues to move upward and over rocker 20, and rocker 20 returns to the horizontal position under the action of second scroll spring 58; then, the hand supports the clapboard 6 to move downwards, and the clapboard 6 meets the swinging block 20 in the first positioning mechanism 7 and the second positioning mechanism 8 again; the swing block 20 swings downwards, and the swing block 20 drives the pressing block 25 to swing towards the stop block 31 through the driving ring 18, the first one-way clutch 19 and the first shaft 21 and compress air; compressed air enters the second pneumatic chamber 34 through the outlet aperture 28 and the inlet aperture 39; because the air outlet hole 28 is connected with the air inlet hole 39 through a thin pipe, the speed of the compressed air entering the second air pressure cavity 34 through the air outlet hole 28 and the air inlet hole 39 is reduced; the partition board 6 stays for three to four seconds on the layer where the first positioning mechanism 7 and the second positioning mechanism 8 are located; then high-pressure air from the first air pressure cavity 27 of the first positioning mechanism 7 and the second positioning mechanism 8 is gathered in the second air pressure cavity 34, so that the arc-shaped block 45 swings around the central axis of the second shaft 42; the second shaft 42 drives the fixture block 52 to swing 91 degrees through the fixture wheel 50, so that the fixture block 52 is positioned at a horizontal position and is in contact with the partition board 6; the plate spring 32 deforms with the rotation of the second shaft 42 and generates a certain torque to the second shaft 42; under the action of high-pressure air in the second air pressure chamber 34, the arc-shaped blocks 45 enable the clamping blocks 52 to lift the partition board 6 through the second shaft 42 and the clamping wheels 50, and further the partition board 6 is fixed on the layer.

In conclusion, the invention has the beneficial effects that: the first positioning mechanism 7, the second positioning mechanism 8, the third positioning mechanism 9, the fourth positioning mechanism 10, the fifth positioning mechanism 11 and the sixth positioning mechanism 12 are hidden in the refrigerator shell 1 when the partition plate 6 is not arranged; when the partition board 6 needs to move from one layer to another layer, the partition board 6 is supported by hands to leave the layer where the partition board 6 is located upwards, then the partition board 6 is supported by hands to move downwards to a target layer, the partition board 6 is supported by hands to stay on the target layer for three to four seconds, and the fixture block 52 of the target layer swings to a horizontal position to lift the partition board 6; thus, the link of drawing the partition board 6 out of the refrigerator is saved, and the procedure of changing the layer of the partition board 6 is saved; meanwhile, the possibility that the partition board 6 slides down to the ground due to the difference between the internal temperature and the external temperature is avoided, and further unnecessary economic loss is avoided; because the refrigerator fresh-keeping door 4 does not need to be completely opened when the partition plate 6 is moved, only a small amount of cold air is leaked from the opening of the fresh-keeping door 4, and the purpose of energy conservation is achieved to a certain extent.
