Description

Technical Field

[0001] This utility model relates to a lid rotation drive mechanism for a double-opening trash can and the trash can itself, belonging to the technical field of household goods. Background Technology

[0002] Trash cans are an indispensable household item. Most trash cans have lids to prevent odors from spreading. Currently, most trash can lids on the market are flip-top type, opened by pressing a button or pressure plate, or stepping on a foot pedal, as seen in patent number "ZL201710844871.5" entitled "A Flip-Top Trash Can". However, flip-top trash cans require sufficient space above the lid to open. When there is obstruction above the trash can, such as when the trash can is under a table, the lid may not fully open during the flip-top process due to contact with the table surface, affecting trash disposal. In addition, after the lid is opened, it is usually tilted above the can body, partially obstructing the trash disposal opening. This obstruction also makes it difficult to throw trash into the can from the back, as trash can easily be ejected by the lid. The portability is significantly affected by the obstruction caused by the lid. Utility Model Content

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. For example... Figure 1-9As shown, the double-lid trash can includes a lid rotation drive mechanism and the trash can itself, comprising a body with a trash disposal opening 21. Two lid bodies 3 are hinged to the inner wall of the trash disposal opening 21. When the two lid bodies 3 are joined together, the trash disposal opening 21 is closed. The trash can also has a transmission mechanism that causes the two lid bodies 3 to rotate. The transmission mechanism includes a drive block 4 that can move longitudinally within the trash can and two transmission blocks 5 that are driven by the drive block 4 to move horizontally in opposite directions. During the horizontal reverse movement, the two transmission blocks 5 drive the two lid bodies 3 to rotate synchronously in opposite directions, thereby opening or closing the trash disposal opening 21.

[0031] In the above technical solution: the transmission mechanism also includes two second springs 7 and several first springs 6. A recessed mounting cavity 22 is provided on the barrel body. The driving block 4 is located within the mounting cavity 22 and can move longitudinally within it. The two ends of the first springs 6 contact the driving block 4 and the bottom of the mounting cavity 22, respectively. Both ends of the bottom of the driving block 4 are provided with first guide slopes 42. The two transmission blocks 5 are each provided with second guide slopes 51. The two transmission blocks 5 are slidably mounted on the barrel body and located on opposite sides of the driving block 4. Two moving holes are provided on the bottom of the mounting cavity 22. The ends of the first guide slopes 42 pass through the moving holes and contact the second guide slopes 51. Two baffles 23 are provided on the barrel body. The two ends of the second springs 7 contact the transmission blocks 5 and the baffles 23, respectively. The same end of the two cover plate bodies 3 passes through the inner wall of the garbage disposal opening 21 and is provided with a transmission gear 31. Both transmission blocks 5 are provided with rack portions 52, and the two transmission gears 31 mesh with the two rack portions 52, respectively. The downward drive block 4, the first guide slope 42 and the second guide slope 51 cooperate to make the two transmission blocks 5 move in opposite directions, the transmission gear 31 rotates, and the two cover plate bodies 3 rotate in opposite directions, the garbage disposal port 21 opens, and at this time the first spring 6 and the second spring 7 are compressed.

[0032] In the above technical solution: First limiting notches 24 are formed on both sides of the mounting cavity 22, and first limiting blocks 41 are provided on both sides of the driving block 4. The first limiting blocks 41 are located within the first limiting notches 24 and can move up and down within the first limiting notches 24. When the first spring 6 is in the extended state, the top surface of the first limiting block 41 contacts the upper wall of the first limiting notch 24, preventing the driving block 4 from disengaging from the mounting cavity 22.

[0033] In the above technical solution: an inverted T-shaped locking block 43 is provided in the middle of the bottom surface of the drive block 4, and a self-locking buckle 10 is provided inside the barrel to lock the movement of the locking block 43. The bottom of the mounting cavity 22 is provided with a mounting opening 28, and two relatively protruding mounting blocks 29 are provided inside the mounting opening 28. Both sides of the self-locking buckle 10 are provided with buckle grooves 101. The bottom of the self-locking buckle 10 is inserted into the mounting opening 28, and the mounting blocks 29 are engaged in the buckle grooves 101, thus completing the detachable installation of the self-locking buckle 10 and the mounting cavity 22. When the drive block 4 is pressed down, the first spring 6 is compressed, the garbage disposal opening 21 is opened, and the locking block 43 moves down until it is locked by the self-locking buckle 10. At this time, the drive block 4 is locked, keeping the garbage disposal opening 21 in the open state. When the drive block 4 is pressed down again, the self-locking buckle 10 unlocks the locking block 43. The first spring 6 is released elastically, causing the drive block 4 and the locking block 43 to move upward. The second spring 7 is released elastically, causing the two transmission blocks 5 to move relative to each other. Through the transmission gear 31, the two cover plates 3 rotate relative to each other until they are in contact and joined together, and the garbage disposal opening is closed. The self-locking buckle 10 can be purchased directly from the market. The structure and locking method of the locking block 43 and the self-locking buckle 10 refer to the structure and locking method of the main buckle and self-locking mechanism in the patent with patent number "202221518742.X" and title "A Portable Sealed Garbage Can". Of course, the self-locking buckle 10 can also be other structures that can achieve self-locking. For example, the self-locking buckle 10 can be the same structure as the one in the patent with patent number "ZL202120988241.7" and title "A self-locking switch".

[0034] In the above technical solutions: such as Figure 6 , 7 As shown, the barrel body is also equipped with two sets of sliding guide strips 26, each with a third insertion inclined surface 27. Sliding guide grooves 53 are formed on the sides of the two transmission blocks 5, with the sliding guide strips 26 located within them, achieving a sliding connection between the transmission blocks 5 and the barrel body. The third insertion inclined surface 27 guides the sliding guide strips 26 as they enter the sliding guide grooves 53. A spring groove is formed within the transmission block 5, with the second spring 7 and the baffle 23 both located within it. The two ends of the second spring 7 contact the groove wall and the baffle 23, respectively. The structures of the two transmission blocks 5 are identical. Figure 9 As shown, rack portions 52 are provided on both the front and rear sides of the bottom of the two transmission blocks 5, so that there is no need to distinguish between left and right parts when installing the transmission blocks 5, which facilitates production and installation.

[0035] In the above technical solution: a pressing top cover 8 is also provided inside the mounting cavity 22, and the pressing top cover 8 is located above the driving block 4. Several third springs 9 are also provided inside the mounting cavity 22, and the third springs 9 are located on the side of the driving block 4. The two ends of the third springs 9 respectively contact the bottom surface of the pressing top cover 8 and the bottom of the groove in the mounting cavity 22. The front and rear sides of the mounting cavity 22 ( Figure 1 The surface adjacent to the foot pedal 16 (which serves as the front of the trash can) is provided with a second limiting notch 25. Both sides of the pressing top cover 8 are provided with second limiting blocks 81. The second limiting blocks 81 engage with the second limiting notches 25 and can move up and down within them. When the third spring 9 is in its extended state, the top surface of the second limiting blocks 81 contacts the upper wall of the second limiting notch 25, preventing the pressing top cover 8 from disengaging from the mounting cavity 22. When the top cover 8 is pressed down, the third spring 9 is compressed, and the top cover 8 moves the drive block 4 downward. When the drive block 4 moves down to be locked by the self-locking buckle 10 and the garbage disposal port 21 is in the open state, the pressing of the top cover 8 is stopped. At this time, the third spring 9 releases its elasticity and moves the top cover 8 upward until the top surface of the second limit block 81 contacts the upper wall of the second limit notch 25. At this time, the top surface of the top cover 8 is slightly exposed in the mounting cavity 22, ensuring the aesthetic appearance and protecting the structure inside the mounting cavity 22, preventing dust and impurities from entering the mounting cavity 22 and interfering with and affecting the unlocking and resetting of the drive block 4.

[0036] In the above technical solution: the bin body includes a bin body 1 and a bin lid 2. The bin lid 2 is located at the top opening of the bin body 1 and is hinged to the top of the bin body 1. The garbage disposal port 21 is located on the top surface of the bin lid 2. The transmission mechanism is located inside the bin lid 2. The mounting cavity 22 is formed by a recess in the top surface of the bin lid 2. The baffle 23 is located at the bottom of the top surface of the bin lid 2. The sliding guide strip 26 is located on the inner wall of the bin lid 2. A foot pedal swing arm 13 is hinged to the bottom of the bin body 1. A connecting rod 14 is provided inside the bin body 1. The two ends of the connecting rod 14 are respectively connected to the foot pedal swing arm 13 and the bin lid 2. The end of the foot pedal swing arm 13 extends out of the bin body 1 and is hinged to a foot pedal 16. A transmission protrusion 17 is formed at the end of the foot pedal swing arm 13, and the foot pedal 16 is located on the transmission protrusion 17. When the foot pedal 16 is pressed, it contacts the transmission convex plate 17 and drives the foot pedal swing arm 13 to rotate relative to the bin body 1. Utilizing the lever action, the bin lid 2 is opened via the connecting rod 14, facilitating the disposal of garbage into the bin body 1. This utility model has two opening methods: a press-to-open double-lid rotation type and a foot pedal flip-up type, making it widely applicable and more convenient to use.

[0037] In the above technical solution: the bin body also includes a mounting frame 11 located between the bin body 1 and the bin lid 2. The bottom of the mounting frame 11 is snapped onto the inner circumferential surface of the bin body 1, and two handles 12 are hinged to the inner circumferential surface of the mounting frame 11. A positioning flange 15 is provided in the middle of the mounting frame 11, which contacts the positioning flange 15 when the bin lid 2 is closed. A bin lid locking block is provided on the bin lid 2, and a corresponding bin body locking block 18 is provided on the mounting frame 11. When the bin lid 2 is closed, the bin lid locking block is engaged with the bottom of the bin body locking block 18, thereby locking the bin lid 2 on the mounting frame 11 and the bin body 1 when closed, preventing the bin lid 2 from automatically opening relative to the bin body 1 when the bin is tilted, causing the garbage inside the bin body 1 to fall out.

[0038] The working process of this utility model is as follows: When it is necessary to open the garbage disposal port 21, press down on the top cover 8, compress the third spring 9, and press the top cover 8 to drive the drive block 4 to move down. The first guide slope 42 and the second guide slope 51 cooperate to make the two transmission blocks 5 move in opposite directions. The transmission gear 31 rotates, causing the two cover plate bodies 3 to rotate in opposite directions, and the garbage disposal port 21 opens. At this time, the first spring 6 and the second spring 7 are compressed. The drive block 4 moves down to the locking block 43 and is locked by the self-locking buckle 10. The two cover plate bodies 3 have rotated and are in a vertical state. The side of the cover plate body 3 contacts the inner wall of the garbage disposal port 21. At this time, the garbage disposal port 21 is fully opened and locked in the open state. Stop pressing down on the top cover 8. At this time, the third spring 9 releases its elasticity and drives the top cover 8 to move up until the top surface of the second limit block 81 contacts the upper wall of the second limit notch 25.

[0039] When it is necessary to close the garbage disposal opening 21, press down on the top cover 8 again. Pressing down on the top cover 8 causes the drive block 4 to move down, and the locking block 43 presses down on the self-locking buckle 10. The self-locking buckle 10 unlocks the locking block 43. Stop pressing down on the top cover 8, and the top cover 8 moves up to reset. The first spring 6 releases elastically, causing the drive block 4 and the locking block 43 to move up. The second spring 7 releases elastically, causing the two transmission blocks 5 to move relative to each other. Through the transmission gear 31, the two cover plate bodies 3 rotate relative to each other until the top surface of the first limiting block 41 on the drive block 4 contacts the upper wall of the first limiting notch 24. The drive block 4 stops moving, and the two cover plate bodies 3 rotate to a state of mutual contact and splicing. The garbage disposal opening 21 is completely closed.

[0040] This utility model features two cover plates 3 that rotate in opposite directions to open the garbage disposal opening 21, employing a double-opening design. This reduces the upward space required for opening the cover plates 3, broadening its applicability. It also minimizes obstruction of the garbage disposal opening 21, allowing it to open more thoroughly and facilitating garbage disposal from all sides. The transmission mechanism is simple and reliable. The locking block 43 and self-locking buckle 10 work together to lock the open cover plates 3, preventing frequent opening of the garbage disposal opening 21 and associated inconvenience. The pressing top cover 8 ensures aesthetic appeal and protects the structure within the mounting cavity 22, preventing dust and impurities from entering and interfering with the unlocking and resetting of the drive block 4. Furthermore, the lid 2 can be rotated open by pressing the foot pedal 16, facilitating garbage disposal into the bin 1. It offers two opening methods: a pressing double-lid rotation and a foot-operated upward flip, making it widely applicable and convenient to use.

[0041] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should fall within the protection scope of this utility model.
