As a further improvement of the present technology, the length difference between the second trapezoidal sliding groove and the first rack is equal to the distance between the limiting block and the T-shaped groove.

As a further improvement of the present technology, the first and second limit plates have elasticity.

The transmission mechanism is designed to ensure that when the garbage bin needs to be opened to throw garbage inwards, if a button is pressed to a limit position first, the button drives a corresponding second gear to rotate through a corresponding second gear which is connected with the button; the pressed button drives the V-shaped sliding block to slide downwards along the V-shaped sliding groove through a pressing block arranged on the pressed button, and the third return spring is stretched; the plurality of second limiting plates arranged on the lower end face of the V-shaped sliding block and the plurality of first limiting plates arranged on the sliding rod are elastic, so that the plurality of first limiting plates and the plurality of second limiting plates interact and deform, and the plurality of first limiting plates and the plurality of second limiting plates are staggered; meanwhile, the second gear corresponding to the pressed button drives the first gear to rotate through the corresponding first rack and the toothed plate; the first gear rotates and simultaneously generates relative linear motion with the other first rack, the first gear drives the square sliding block to slide towards the first sliding hole along the first trapezoid sliding groove through the first shaft, the telescopic column contracts, and the first return spring is compressed; at the moment, the absolute sliding speed of the first rack is twice of the linear movement speed of the gear; since the distance between the meshing point of the toothed plate and the first gear and the end of the toothed plate far away from the first transmission groove is equal to the length difference 1/2 between the second trapezoidal sliding groove and the first rack, the first rack corresponding to the pressed button slides to the limit position along the corresponding second trapezoidal sliding groove, and the toothed plate on the first rack corresponding to the pressed button is just separated from the first gear; at the moment, the first gear drives the square sliding block to slide along the first trapezoidal sliding groove for 1/2 corresponding to the first rack corresponding to the pressed button in a sliding displacement manner, and the sliding rod drives the limiting block to slide for the same distance as the square sliding block; because the length difference between the second trapezoidal sliding groove and the first rack is equal to the distance between the limiting block and the T-shaped groove, the limiting block only moves for a half stroke under the driving of the square sliding block and the sliding rod, and the limiting block and the T-shaped groove are still separated for a half stroke; the first limiting plates arranged on the lower end face of the V-shaped sliding block are staggered with the second limiting plates arranged on the sliding rod, and the first limiting plates and the second limiting plates interact with each other, so that the sliding rod cannot drive the square sliding block and the first gear to reset under the action of the first reset spring, and the first gear and the square sliding block are kept still after a toothed plate on a first rack corresponding to a pressed button is separated from the first gear; because the distance between the meshing point of the toothed plate and the first gear and one end, close to the first transmission groove, of the toothed plate is greater than the length difference between the second trapezoidal sliding groove and the first gear rack, when the toothed plate on the first gear rack corresponding to the pressed button is separated from the first gear rack, the toothed plate on the other first gear rack is still meshed with the first gear rack; the pressed button is continuously pressed, no matter how far the second button is pressed, the second button drives the gear to idle through the corresponding second rack, the second gear, the first rack and the toothed plate, and the first gear and the direction sliding block can not continuously slide to the direction of the first sliding hole along the first trapezoidal sliding groove; the slide bar and the limiting block do not move towards the T-shaped groove any longer; the limiting block still keeps limiting the downward swing of the barrel cover; the clamping block arranged on the barrel cover cannot interact with the pressing buckle, the pressing buckle cannot unlock the clamping block, and the barrel cover cannot be opened; if the second button is pressed before the first button is pressed to the limit position, the first gear does not stop rotating under the combined action of the two toothed plates on the two first racks; the first gear and the direction sliding block can continuously slide towards the direction of the first sliding hole along the first trapezoidal sliding groove under the driving of the two toothed plates on the two first racks on the basis of the distance of movement before the second button is pressed; when the button pressed down first reaches the limit position, the corresponding second rack, the second gear, the first rack and the toothed plate simultaneously move to the limit position and do not move any more; the button pressed down then continues to move to the extreme position; under the action of the toothed plate corresponding to the button pressed first, the button pressed later sequentially passes through the corresponding second rack and the second gear, and the first rack and the toothed plate drive the first gear to rotate; the first gear rotates and moves linearly along the direction from the other toothed plate to the first sliding hole; because the distance between the meshing point of the toothed plate and the first gear and the end, far away from the first transmission groove, of the toothed plate is equal to 1/2 of the length difference between the second trapezoidal sliding groove and the first rack, the distance between the meshing point of the toothed plate and the first gear and the end, close to the first transmission groove, of the toothed plate is larger than the length difference between the second trapezoidal sliding groove and the first rack, and the length difference between the second trapezoidal sliding groove and the first rack is equal to the distance between the limiting block and the T-shaped groove, when the first rack corresponding to a pressed button slides to a limit position along the corresponding second trapezoidal sliding groove, the first gear drives the limiting block to move to the position above the T-shaped groove just through the direction sliding block and the sliding rod and enter the T-shaped groove; under the condition of continuously applying pressure, the clamping block interacts with the pressing buckle, the pressing buckle unlocks the clamping block, then the pressure applied to the barrel cover is removed, and the barrel cover swings upwards around the central axis of the swing shaft and is opened under the action of the volute spiral spring; if the two buttons are pressed down to the limit position at the same time when the garbage is thrown, the first gear does not rotate under the combined action of the two toothed plates on the two first racks because the movement of the two buttons is synchronous; the two toothed plates drive the first gear and the direction sliding block to move to the limit position towards the direction of the first sliding hole together; the limiting block moves to the upper part of the T-shaped groove and enters the T-shaped groove; under the condition of continuously applying pressure, the clamping block interacts with the pressing buckle, the pressing buckle unlocks the clamping block, then the pressure applied to the barrel cover is removed, and the barrel cover swings upwards around the central axis of the swing shaft and is opened under the action of the volute spiral spring; after the garbage is put into the garbage can, the can cover is pressed down by hands until the buckle is pressed; simultaneously pressing the two buttons to the limit position, and moving the limiting block to the position above the T-shaped groove and entering the T-shaped groove; continuously applying pressure, enabling the fixture block to enter a pressing buckle and further interact with the pressing buckle, self-locking the fixture block by the pressing buckle, and then removing the pressure barrel cover applied on the barrel cover; the two buttons are pressed to the limit positions simultaneously or one button is pressed to the limit position before the other button is pressed and reaches the limit positions successively, the dustbin cover can be opened or closed, and due to the common limitation of the length of fingers of the children and the lack of finger control capability of the brain, the children cannot simultaneously use the two fingers to act on the two buttons to synchronously operate and open the dustbin cover, so that the situation that the children with incomplete mind open the dustbin at will is avoided, and the situation that the health of the children is not influenced due to misopening is further ensured.

In conclusion, the invention has the beneficial effects that: the special structure of the limit synchronous mechanism limits the opening or locking of the pressing buckle in the garbage can; on one hand, the garbage can is prevented from being accidentally touched and being scattered randomly from the garbage can to influence the environment; on the other hand, if only one button is pressed, the limiting block cannot enter the T-shaped groove, and the barrel cover of the garbage can cannot be locked or unlocked; only when the two buttons are synchronously pressed, the barrel cover can be opened or closed, so that the health of children with incompetent mind can not be influenced by mistakenly opening the garbage can; the invention has simple structure and better use effect.

As shown in fig. 22 and 23, both the first stopper plate 32 and the second stopper plate 40 have elasticity.

The purpose of the transmission mechanism 14 of the present invention is that, when the trash can needs to be opened to throw the trash inwards, if a button 44 is pressed to the limit position first, the button 44 drives the corresponding second gear 38 to rotate through the corresponding second rack 43 connected with the button; the pressed button 44 drives the V-shaped slide block 39 to slide downwards along the V-shaped sliding groove 22 through the press block 46 mounted on the pressed button, and the third return spring 41 is stretched; because the plurality of second limiting plates 40 arranged on the lower end surface of the V-shaped sliding block 39 and the plurality of first limiting plates 32 arranged on the sliding rod 30 have elasticity, the plurality of first limiting plates 32 and the plurality of second limiting plates 40 interact and deform, and the plurality of first limiting plates 32 and the plurality of second limiting plates 40 are staggered; at the same time, the second gear 38, corresponding to the button 44 being pressed, rotates the first gear 29 through the respective first rack 34 and toothed plate 36; the first gear 29 rotates and moves linearly relative to the other first rack 34, the first gear 29 drives the square sliding block 26 to slide along the first trapezoidal sliding groove 18 towards the first sliding hole 20 through the first shaft 28, the telescopic column 47 contracts, and the first return spring 48 is compressed; at this time, the absolute sliding speed of the first rack 34 is twice the linear movement speed of the gear; since the distance between the meshing point of the toothed plate 36 and the first gear 29 and the end of the toothed plate 36 far from the first transmission groove 16 is equal to the length difference 1/2 between the second trapezoidal sliding groove 19 and the first rack 34, the first rack 34 corresponding to the pressed button 44 slides along the corresponding second trapezoidal sliding groove 19 to the extreme position, and the toothed plate 36 on the first rack 34 corresponding to the pressed button 44 just disengages from the first gear 29; at this time, the distance that the first gear 29 drives the square sliding block 26 to slide along the first trapezoidal sliding groove 18 is 1/2 that the first rack 34 corresponding to the pressed button 44 slides, and the sliding rod 30 drives the limit block 33 to slide by the same distance as the square sliding block 26; because the length difference between the second trapezoidal sliding groove 19 and the first rack 34 is equal to the distance between the limiting block 33 and the T-shaped groove 3, the limiting block 33 only moves by a half stroke under the driving of the square sliding block 26 and the sliding rod 30, and at this time, the limiting block 33 is still spaced from the T-shaped groove 3 by a half stroke; since the first limit plates 32 installed on the lower end surface of the V-shaped sliding block 39 are staggered with the second limit plates 40 installed on the sliding rod 30, and the first limit plates 32 interact with the second limit plates 40, so that the sliding rod 30 cannot drive the square sliding block 26 and the first gear 29 to reset under the action of the first return spring 48, when the toothed plate 36 on the first rack 34 corresponding to the pressed button 44 is separated from the first gear 29, the first gear 29 and the square sliding block 26 keep still; since the distance between the meshing point of the toothed plate 36 and the first gear 29 and the end of the toothed plate 36 close to the first transmission groove 16 is greater than the length difference between the second trapezoidal sliding groove 19 and the first gear rack 34, when the toothed plate 36 on the first gear rack 34 corresponding to the pressed button 44 is disengaged from the first gear 29, the toothed plate 36 on the other first gear rack 34 is still meshed with the first gear 29; the pressed button 44 is kept pressed continuously, and when the second button 44 is pressed continuously, no matter how far the second button 44 is pressed, the second button 44 drives the gears to idle through the corresponding second rack 43, the second gear 38, the first rack 34 and the toothed plate 36, and the first gear 29 and the direction slider cannot slide along the first trapezoidal sliding groove 18 to the direction of the first sliding hole 20 any more; the slide bar 30 and the limited block 33 can not move to the T-shaped groove 3 any more; the limiting block 33 still keeps limiting the downward swing of the barrel cover 5; the clamping block 10 arranged on the barrel cover 5 cannot interact with the pressing buckle 13, the pressing buckle 13 cannot unlock the clamping block 10, and the barrel cover 5 cannot be opened; if the second push-button 44 is pressed before the one push-button 44 is pressed to the limit position, the first gear 29 will not stop rotating under the action of the two toothed plates 36 on the two first racks 34; the first gear 29 and the direction slider will slide continuously along the first trapezoidal sliding groove 18 towards the first sliding hole 20 under the driving of the two toothed plates 36 on the two first racks 34 based on the distance of movement before the second button 44 is pressed; when the button 44, which is pressed first, reaches the limit position, the second rack 43, the second gear 38, the first rack 34 and the toothed plate 36 corresponding thereto simultaneously move to the limit position without further movement; the button 44, which is then pressed, continues to move towards the extreme position; under the action of the toothed plate 36 corresponding to the button 44 pressed first, the button 44 pressed later passes through the corresponding second rack 43 and the second gear 38 in sequence, and the first rack 34 and the toothed plate 36 drive the first gear 29 to rotate; the first gear 29 rotates and moves linearly along the other tooth plate 36 toward the first sliding hole 20; since the distance between the meshing point of the toothed plate 36 and the first gear 29 and the end of the toothed plate 36 far away from the first transmission groove 16 is equal to 1/2 of the length difference between the second trapezoidal sliding groove 19 and the first rack 34, the distance between the meshing point of the toothed plate 36 and the first gear 29 and the end of the toothed plate 36 close to the first transmission groove 16 is greater than the length difference between the second trapezoidal sliding groove 19 and the first rack 34, and the length difference between the second trapezoidal sliding groove 19 and the first rack 34 is equal to the distance between the limit block 33 and the T-shaped groove 3, when the first rack 34 corresponding to the button 44 pressed down after slides to the limit position along the corresponding second trapezoidal sliding groove 19, the first gear 29 drives the limit block 33 to move just above the T-shaped groove 3 and enter the T-shaped groove 3 through the direction slider and the slide bar 30; under the condition of continuously applying pressure, the clamping block 10 interacts with the pressing buckle 13, the pressing buckle 13 unlocks the clamping block 10, then the pressure applied to the barrel cover 5 is removed, and the barrel cover 5 swings upwards around the central axis of the swing shaft 12 and is opened under the action of the volute spiral spring 11; if the two push buttons 44 are pressed down to the extreme position at the same time when throwing the garbage, the first gear 29 is not rotated by the cooperation of the two toothed plates 36 on the two first racks 34 because the movement of the two push buttons 44 is synchronized; the two toothed plates 36 drive the first gear 29 and the direction slider to move to the limit position in the direction of the first sliding hole 20; the limiting block 33 moves to the upper part of the T-shaped groove 3 and enters the T-shaped groove 3; under the condition of continuously applying pressure, the clamping block 10 interacts with the pressing buckle 13, the pressing buckle 13 unlocks the clamping block 10, then the pressure applied to the barrel cover 5 is removed, and the barrel cover 5 swings upwards around the central axis of the swing shaft 12 and is opened under the action of the volute spiral spring 11; after the garbage is put into the garbage can, the can cover 5 is pressed down by hands to be swung to the position of the pressing buckle 13; then, the two buttons 44 are pressed to the limiting position, and the limiting block 33 moves to the upper part of the T-shaped groove 3 and enters the T-shaped groove 3; continuously applying pressure, enabling the fixture block 10 to enter the pressing buckle 13 and further interact with the pressing buckle 13, carrying out self-locking on the fixture block 10 by the pressing buckle 13, and then removing the pressure barrel cover 5 applied on the barrel cover 5 to be covered; when the two buttons 44 are pressed to the limit positions simultaneously or one button 44 is pressed before the other button 44 is pressed to the limit positions and reaches the limit positions successively, the dustbin cover 5 can be opened or closed, and due to the common limitation of the length of fingers of a child and the lack of finger control capability of the brain of the child, the child cannot act on the two buttons 44 simultaneously by using two fingers to synchronously operate and open the dustbin cover 5, so that the situation that the child with incomplete mind randomly opens the dustbin is avoided, and the situation that the health of the child is not influenced by mistaken opening is further ensured.
