As a further improvement of the present technology, the return spring is a compression spring.

As a further improvement of the present technology, the four return springs in the second drawer unit have spring forces 1.5 times the spring forces of the corresponding spiral springs; 1.5 times can make the spacing of gag lever post internal thread cover reach a better effect.

For the first drawer unit and the second drawer unit, the rear end of the drawer is arranged on the rear side surface in the goods shelf through the swinging support lug, the fixed support lug and the fixed rotating shaft; the drawer can swing relative to the goods shelf; under a normal state, two corresponding supporting blocks which are positioned at the front side of the drawer and are arranged on the goods shelf or the fixed supporting plate support the corresponding first connecting plate and second connecting plate to form an inverted L-shaped clamping plate, and the first connecting plate and the second connecting plate support the corresponding driving plates and the trapezoidal guide blocks; the driving plate and the trapezoidal guide block play a supporting role on the front end of the drawer; namely, the two corresponding supporting blocks which are positioned at the front side of the drawer and are arranged on the goods shelf or the fixed supporting plate play a role in supporting the front end of the drawer; the drawer is in a horizontal state under a normal state, and the drawer is convenient to store articles.

For the first drawer unit and the second drawer unit, when the driving rod is driven to move outwards, the driving rod can drive the two shaft sleeves arranged on the driving rod to move outwards; the two shaft sleeves move outwards to drive the two corresponding mounting plates to move outwards; the two mounting plates can drive the two tooth plates mounted on the mounting plates to move when moving; the two tooth plates are in contact engagement with the two corresponding second gears, and the two tooth plates drive the two second gears to rotate; the second gear rotates to drive the first gear meshed with the second gear to rotate; the first gear rotates to drive the swinging shaft to rotate; the swinging shaft rotates to drive the corresponding swinging baffle to swing; the swinging baffle swings to drive the limiting plate arranged on the swinging baffle to swing; when the swing baffle swings ninety degrees, the corresponding second gear is just disengaged from the tooth plate arranged on the mounting plate; at the moment, a limiting plate arranged on the swinging baffle is just contacted with the bottom side surface of the drawer shell, the bottom side surface of the drawer shell plays a limiting role on the swinging baffle through the limiting plate, and the swinging baffle is prevented from continuously swinging downwards under the action of self gravity to interfere with the return of the driving rod; in the process that the mounting plate moves outwards, the mounting plate can drive the driving plate, the first connecting plate, the second connecting plate and the trapezoidal guide block to move outwards; in the moving process of one connecting plate and the second connecting plate, when the first connecting plate and the second connecting plate are completely separated from the corresponding supporting blocks, the supporting blocks lose the supporting function on the first connecting plate and the second connecting plate, namely the supporting blocks lose the supporting function on the drawer, and in the state, the drawer can swing relative to the goods shelf; in the moving process of the trapezoidal guide block, the trapezoidal guide block can stretch the return spring; so that the return spring is in a stretched state; the return spring has the function of returning the trapezoidal guide block; when the trapezoidal guide block returns under the action of the corresponding return spring, the trapezoidal guide block drives the drive plate, the first connecting plate, the second connecting plate and the mounting plate to return; the mounting plate moves to drive the tooth plates mounted on the mounting plate to move; when the tooth plates are in contact engagement with the corresponding second gears, the tooth plates can drive the second gears to rotate reversely; the second gear rotates reversely to drive the first gear engaged with the second gear to rotate; the first gear rotates to drive the swinging shaft to rotate reversely; the swinging shaft rotates to drive the corresponding swinging baffle to swing upwards; the swinging baffle swings to drive the limiting plate arranged on the swinging baffle to swing upwards; when the swing baffle swings upwards by ninety degrees and returns to the original position, the corresponding second gear is just separated from the tooth plate arranged on the mounting plate; at the moment, the shaft sleeve is also restored to the original position under the driving of the corresponding mounting plate; the drive rod is also returned to its original position.

For the second drawer unit, in a normal state, the driving sleeve and the internal thread sleeve are matched with the third connecting plate and the first square notch formed in the shaft sleeve, and the driving sleeve and the internal thread sleeve are in a static state relative to the shaft sleeve in the rotating direction; the shaft sleeve is fixedly arranged on the mounting plate and is in a static state; when the driving rod is rotated, the driving rod can drive the external thread sleeves arranged at the two ends to rotate; because the external thread sleeve and the internal thread sleeve are in thread fit, and the internal thread sleeve is in a static state in the rotating direction, the two internal thread sleeves can transversely move to the two ends of the driving rod along the axis of the driving rod by the rotation of the driving rod; the two internal thread sleeves move to drive the two driving sleeves connected with the internal thread sleeves through the third connecting plate to transversely move towards the two ends of the driving rod along the axis of the driving rod; so that two drive sleeves are nested on the shaft sleeves in two first drawer units adjacent to the second drawer unit.

For the second drawer unit, when the first connecting plate and the second connecting plate are completely separated from the corresponding supporting blocks, the drawer is swung downwards, the driving rod is stopped being driven outwards after the drawer swings downwards, and at the moment, the trapezoidal guide block drives the driving plate, the first connecting plate, the second connecting plate and the mounting plate to move back under the action of the return spring; however, the drawer is in a downward swinging state at the moment, namely the corresponding supporting blocks are positioned on the upper sides of the first connecting plate and the second connecting plate; therefore, in the process that the trapezoidal guide block drives the driving plate, the first connecting plate, the second connecting plate and the mounting plate to move back, the supporting block can be contacted with the trigger plate arranged on one side of the mounting plate, and the trigger plate can be subjected to extrusion force of the supporting block under the action of the return spring; the trigger plate can drive the limiting rod to move towards one side provided with the internal thread sleeve under the action of the extrusion force; the limiting rod is in contact with the internal thread sleeve and has certain extrusion force on the internal thread sleeve; in the state, the internal thread sleeve is in a static state, and in the rotating process of the driving rod, the driving rod and the corresponding shaft sleeve rotate mutually in the rotating direction; namely, the scroll spring is forced during the rotation of the driving rod; but since the four return springs in the second drawer unit have a greater elastic force than the corresponding wrap springs; therefore, when the supporting block is positioned on the upper sides of the first connecting plate and the second connecting plate and under the action of the return springs, the trigger plate receives extrusion force of the supporting block, and under the action of the four return springs, the extrusion force of the limiting rod on the internal thread sleeve can not enable the driving rod to rotate reversely due to the reaction force of the volute spiral spring.

Compared with the traditional shelf technology, the drawer in the shelf designed by the invention can be manually controlled to swing downwards by ninety degrees by the swing baffle on the front side of the drawer in the cleaning process, so that the rear side surface of the swing baffle is flush with the lower side surface of the drawer; then the drawer swings downwards for a certain angle; cleaning the inner side of the drawer; dirt on the inner side of the drawer is prevented from being difficult to clean due to the fact that the swing baffle is 90 degrees to the bottom side face of the drawer; meanwhile, the drawer swings downwards for a certain angle, so that dirt on the inner side of the drawer can be better cleaned.

In summary, the following steps:

the beneficial effects of the design of the invention are as follows: during cleaning of the drawer 7 in the shelf 3, the swinging baffle 6 at the front side of the drawer 7 can be manually controlled to swing ninety degrees downwards, so that the rear side surface of the swinging baffle 6 is flush with the lower side surface of the drawer 7; then the drawer 7 is swung downwards by a certain angle; cleaning the inner side of the drawer 7; preventing dirt inside the drawer 7 from being difficult to clean because the swinging baffle 6 and the bottom side of the drawer 7 form an angle of 90 degrees; meanwhile, the drawer 7 swings downwards for a certain angle, so that dirt on the inner side of the drawer 7 can be better cleaned.

For the first drawer unit 1 and the second drawer unit 2, the rear end of a drawer 7 is arranged on the rear side surface in a goods shelf 3 through a swinging support lug 8, a fixed support lug 9 and a fixed rotating shaft 10; the drawer 7 can swing relative to the goods shelf 3; in a normal state, the two corresponding supporting blocks 5 which are positioned at the front side of the drawer 7 and are arranged on the goods shelf 3 or the fixed supporting plate 4 form an inverted L-shaped clamping plate to play a supporting role on the corresponding first connecting plate 18 and second connecting plate 20, and the first connecting plate 18 and second connecting plate 20 play a supporting role on the corresponding driving plate 21 and trapezoidal guide block 14; the driving plate 21 and the trapezoidal guide block 14 support the front end of the drawer 7; namely, the two corresponding supporting blocks 5 which are positioned at the front side of the drawer 7 and are arranged on the goods shelf 3 or the fixed supporting plate 4 play a role in supporting the front end of the drawer 7; so that the drawer 7 is in a horizontal state in a normal state, and the drawer 7 is convenient to store articles.

In the invention, for the first drawer unit 1 and the second drawer unit 2, when the driving rod 11 is driven to move outwards, the driving rod 11 drives the two shaft sleeves 12 arranged on the driving rod to move outwards; the two shaft sleeves 12 move outwards to drive the two corresponding mounting plates 19 to move outwards; the two mounting plates 19 move to drive the two tooth plates mounted on the mounting plates to move; two tooth plates are in contact engagement with two corresponding second gears 17, and the two tooth plates drive the two second gears 17 to rotate; the second gear 17 rotates to drive the first gear 15 meshed with the second gear to rotate; the first gear 15 rotates to drive the swinging shaft 22 to rotate; the swing shaft 22 rotates to drive the corresponding swing baffle 6 to swing; the swinging baffle 6 swings to drive the limiting plate 16 arranged on the swinging baffle to swing; when the swing baffle 6 swings ninety degrees, the corresponding second gear 17 is just disengaged from the toothed plate mounted on the mounting plate 19; at the moment, the limit plate 16 arranged on the swinging baffle 6 is just contacted with the bottom side surface of the shell of the drawer 7, and the bottom side surface of the shell of the drawer 7 plays a limit role on the swinging baffle 6 through the limit plate 16, so that the swinging baffle 6 is prevented from continuously swinging downwards under the action of self gravity to interfere with the return of the driving rod 11; in the process that the mounting plate 19 moves outwards, the mounting plate 19 drives the driving plate 21, the first connecting plate 18, the second connecting plate 20 and the trapezoidal guide block 14 to move outwards; when the first connecting plate 18 and the second connecting plate 20 are completely separated from the corresponding supporting blocks 5 in the moving process of one connecting plate and the second connecting plate 20, the supporting blocks 5 lose the supporting function of the first connecting plate 18 and the second connecting plate 20, namely the supporting blocks 5 lose the supporting function of the drawer 7, and in this state, the drawer 7 can swing relative to the goods shelf 3; during the movement of the trapezoidal guide block 14, the trapezoidal guide block 14 stretches the return spring 13; so that the return spring 13 is in a stretched state; the return spring 13 plays a role in returning the trapezoidal guide block 14; when the trapezoidal guide block 14 returns under the action of the corresponding return spring 13, the trapezoidal guide block 14 drives the drive plate 21, the first connecting plate 18, the second connecting plate 20 and the mounting plate 19 to move back; the mounting plate 19 moves to drive the tooth plates mounted on the mounting plate to move; when the tooth plates are in contact engagement with the corresponding second gears 17, the tooth plates drive the second gears 17 to rotate reversely; the second gear 17 rotates reversely to drive the first gear 15 engaged with the second gear to rotate; the first gear 15 rotates to drive the swinging shaft 22 to rotate reversely; the swing shaft 22 rotates to drive the corresponding swing baffle 6 to swing upwards; the swinging baffle 6 swings to drive the limiting plate 16 arranged on the swinging baffle to swing upwards; when the swing baffle 6 swings upwards by ninety degrees and returns to the original position, the corresponding second gear 17 is just disengaged from the tooth plate arranged on the mounting plate 19; at the moment, the shaft sleeve 12 is also restored to the original position under the driving of the corresponding mounting plate 19; the drive rod 11 is also restored to its original position.

In the present invention, for the second drawer unit 2, under the normal condition, the driving sleeve 26 and the internal thread sleeve 35 are in the static state relative to the shaft sleeve 12 in the rotation direction under the matching of the third connecting plate 36 and the first square notch 31 opened on the shaft sleeve 12; the shaft sleeve 12 is fixedly arranged on the mounting plate 19 and is in a static state; when the driving rod 11 is rotated, the driving rod 11 drives the external thread sleeves 28 arranged at the two ends to rotate; because the external thread sleeve 28 and the internal thread sleeve 35 are in thread fit, and the internal thread sleeve 35 is in a static state in the rotating direction, the rotation of the driving rod 11 can cause the two internal thread sleeves 35 to transversely move towards the two ends of the driving rod 11 along the axis of the driving rod 11; the two internal thread sleeves 35 move to drive the two driving sleeves 26 connected with the two internal thread sleeves through the third connecting plate 36 to transversely move towards the two ends of the driving rod 11 along the axis of the driving rod 11; as shown in fig. 29b, so that two drive sleeves 26 are nested on the bushings 12 in two first drawer units 1 adjacent to the second drawer unit 2.

For the second drawer unit 2, when the first connecting plate 18 and the second connecting plate 20 are completely separated from the corresponding supporting block 5, the drawer 7 is swung downwards, after the drawer 7 is swung downwards, the driving rod 11 is stopped being driven outwards, and at the moment, under the action of the return spring 13, the trapezoidal guide block 14 can drive the driving plate 21, the first connecting plate 18, the second connecting plate 20 and the mounting plate 19 to move back; however, since the drawer 7 is in the downward swinging state, the corresponding support block 5 is located on the upper side of the first connecting plate 18 and the second connecting plate 20; therefore, in the process that the trapezoidal guide block 14 drives the driving plate 21, the first connecting plate 18, the second connecting plate 20 and the mounting plate 19 to move back, the supporting block 5 contacts with the trigger plate 29 arranged on one side of the mounting plate 19, and under the action of the return spring 13, the trigger plate 29 is subjected to an extrusion force of the supporting block 5; the trigger plate 29 drives the limiting rod 30 to move towards the side provided with the internal thread sleeve 35 under the action of the extrusion force; so that the limiting rod 30 is in contact with the internal thread bush 35 and the limiting rod 30 has certain extrusion force on the internal thread bush 35; in this state, the internal thread sleeve 35 is in a static state, and during the rotation of the driving rod 11, the driving rod 11 and the corresponding shaft sleeve 12 rotate mutually in the rotation direction; that is, during rotation of drive lever 11, scroll spring 27 is forced; but since the four return springs 33 in the second drawer unit 2 have a greater spring force than the corresponding wrap springs 27; therefore, when the supporting block 5 is located at the upper side of the first connecting plate 18 and the second connecting plate 20 and the trigger plate 29 receives a pressing force of the supporting block 5 by the return spring 13, the pressing force of the stopper rod 30 to the internal thread bush 35 by the four return springs 33 does not cause the reverse rotation of the driving lever 11 by the reaction force of the spiral spring 27.

The specific implementation mode is as follows: when the goods shelf 3 designed by the invention is used, the front end of the drawer 7 is supported by the corresponding supporting block 5 in normal use; so that the drawer 7 is in a horizontal state in a normal state, and the drawer 7 is convenient to store articles. When the drawers 7 on the shelf 3 are cleaned, if the three drawers 7 in the same row are cleaned independently, the driving rod 11 is pulled to move outwards, and the driving rod 11 can drive the two corresponding shaft sleeves 12 to move outwards; the two shaft sleeves 12 move outwards to drive the two corresponding mounting plates 19 to move outwards; the two mounting plates 19 move to rotate the corresponding two second gears 17; the second gear 17 rotates to drive the first gear 15 meshed with the second gear to rotate; the first gear 15 rotates to drive the swinging shaft 22 to rotate; the swing shaft 22 rotates to drive the corresponding swing baffle 6 to swing; swing the swing gate 6 ninety degrees; the rear side of the swing baffle 6 is flush with the lower side of the drawer 7; then, the driving rod 11 is pulled continuously, when the driving rod 11 is pulled to the outermost side, the driving rod 11 is driven manually, so that the driving rod 11 drives the drawer 7 to swing downwards through the corresponding shaft sleeve 12, the mounting plate 19, the driving plate 21 and the trapezoid guide block 14; so that the drawer 7 forms a certain angle with the rear side of the goods shelf 3; at this time, the driving rod 11 is stopped being driven, and the corresponding shaft sleeve 12, the mounting plate 19, the driving plate 21 and the trapezoidal guide block 14 will recover to a certain distance under the action of the corresponding return spring 13; but does not affect the downward swinging of the drawer 7; after this, the inside of the drawer 7 can be cleaned; dirt inside the drawer 7 is prevented from being difficult to clean because the swing baffle 6 is at 90 degrees to the bottom side of the drawer 7. After cleaning is finished, the drive rod 11 drives the drawer 7 to swing upwards, so that the drawer 7 is in a horizontal state, and when the drawer 7 is in the horizontal state, the trapezoidal guide block 14, the drive plate 21, the first connecting plate 18, the second connecting plate 20 and the mounting plate 19 can move back under the action of the corresponding return spring 13; the movement of the mounting plate 19 causes the corresponding swing shutter 6 to swing upwards; when the swing baffle 6 swings upwards by ninety degrees and returns to the original position, the corresponding second gear 17 is just disengaged from the tooth plate arranged on the mounting plate 19; at the moment, the shaft sleeve 12 is also restored to the original position under the driving of the corresponding mounting plate 19; the drive rod 11 is also restored to its original position. When three drawers 7 in the same row need to be cleaned, in order to reduce the time consumed in the cleaning process one by one, in this state, the driving rod 11 in the middle second drawer unit 2 is rotated, and the driving rod 11 is rotated to enable the two internal thread sleeves 35 to transversely move towards the two ends of the driving rod 11 along the axis of the driving rod 11; the two internal thread sleeves 35 move to drive the two driving sleeves 26 connected with the two internal thread sleeves through the third connecting plate 36 to transversely move towards the two ends of the driving rod 11 along the axis of the driving rod 11; so that two drive sleeves 26 are nested on the shaft sleeves 12 in two first drawer units 1 adjacent to the second drawer unit 2; when a drive sleeve 26 is nested on the bosses 12 in two first drawer units 1 adjacent to the second drawer unit 2; driving the driving rod 11 located in the middle second drawer unit 2 so that the driving rod 11 drives the two adjacent driving rods 11 to move; so that the three drawers 7 in the same row simultaneously swing downwards for a certain angle; then cleaning is carried out; after cleaning is finished, the drive rod 11 in the middle second drawer unit 2 drives the drawer 7 to swing upwards, so that the drawer 7 is in a horizontal state, when the drawer 7 is in the horizontal state, the trigger plate 29 in the middle second drawer unit 2 loses the limiting effect of the corresponding support block 5 on the trigger plate, and at the moment, under the action of the volute spiral spring 27, the drive rod 11 in the middle second drawer unit 2 rotates reversely; so that the driving sleeve 26 in the middle second drawer unit 2 is separated from the shaft sleeves 12 in the two adjacent first drawer units 1; at the moment, the three drawers 7 in the same row can be restored to the original positions under the action of the corresponding return springs 13; when three drawers 7 in the same row need to be restored simultaneously, the drive rod 11 in the middle second drawer unit 2 is manually controlled to rotate, so that the two drive sleeves 26 in the middle second drawer unit 2 are nested on the shaft sleeves 12 in the two adjacent first drawer units 1, and at this time, the three drawers 7 can be restored simultaneously under the action of the corresponding return springs 13.
