Description

Technical Field

[0001] This utility model relates to a trash can, specifically a drive structure for a double-opening trash can lid. Background Technology

[0002] As disclosed in CN221564357U, a double-door small cover opening and closing mechanism and an intelligent trash can include a base with a trash disposal opening on the base. A small cover is provided on the base to cover the trash disposal opening. One end of the small cover is a driving end, and the other end is a driven end. The driving end is rotatably connected to the outside of one side of the trash disposal opening through the opening and closing mechanism, and the driven end is rotatably connected to the outside of the other side of the trash disposal opening. The small cover includes a left small cover and a right small cover. The opening and closing mechanism includes a driving device and a transmission mechanism. The driving device is installed on the base outside the trash disposal opening, and the transmission mechanism includes a transmission rod, a first stroke adjustment rod, and a second stroke adjustment rod. In this utility model, the driving device does not need to be installed in the center of the base, and the installation position of the driving device can be flexibly set without obstructing the installation of other mechanisms.

[0003] However, the above structure uses a transmission rod, a first stroke adjusting rod, and a second stroke adjusting rod. Since the wheelbase of the two small lids of different sizes of trash cans is different, the first stroke adjusting rod and the second stroke adjusting rod cannot be used interchangeably. In addition, the transmission mechanism uses three connecting rods, and the first stroke adjusting rod and the second stroke adjusting rod also need to be connected to the first rotating shaft and the second rotating shaft, respectively. The transmission mechanism is not compact enough and is relatively complicated to assemble. Utility Model Content

[0004] The purpose of this utility model is to provide a drive structure for a double-lid trash can, in which one of the flip-tops of the trash can is directly driven by the output shaft of the drive mechanism, and the two flip-tops are synchronously linked by only one connecting rod. It has the characteristics of compact structure and convenient assembly.

[0005] The following technologies are used to achieve the above objectives:

[0006] A driving structure for a double-lid trash can includes a base, a trash inlet on the base, and two flip-tops at the trash inlet. The two flip-tops, when joined together, match the shape of the trash inlet. The two ends of the two flip-tops are pivotally connected to the inner wall of the trash inlet via a driven end and a driving end, respectively. A driving device is provided on the outer side of the trash inlet on the base. The characteristic feature is that the two flip-tops are an active flip-top and a driven flip-top, respectively. The output shaft of the driving device is directly coaxially connected to the driving end of the active flip-top. The driving end of the active flip-top and the driving end of the driven flip-top are connected by a connecting rod or chain. When the active flip-top rotates, it drives the driven flip-top to rotate synchronously in the opposite direction through the connecting rod or chain.

[0007] The two connection points of the connecting rod on the driving end are both located on the periphery of the driving end axis, and the phase difference between the two connection points on the two driving ends (31) is between π / 2 and π.

[0008] Both the driving end and the driven end include a positioning protrusion ring and a positioning sleeve. The positioning protrusion ring is set at the end of the flip cover. A shaft hole is opened on the inner wall of the garbage disposal port corresponding to the position of the positioning protrusion ring. The positioning protrusion ring passes through the shaft hole, and the positioning sleeve is sleeved on the positioning protrusion ring on the other side of the shaft hole, so that the flip cover is pivotally connected to the inner wall of the garbage disposal port.

[0009] The positioning ring also has an axially protruding latch, and the positioning sleeve has a locking hole that cooperates with the latch. The latch engages with the locking hole to axially position the positioning ring and the positioning sleeve.

[0010] The positioning sleeve is provided with a positioning ring that cooperates with the positioning convex ring. The cooperation between the positioning ring and the positioning convex ring ensures that the positioning convex ring and the positioning sleeve are coaxial.

[0011] The outer end face of the positioning sleeve of the active flip cover drive end is provided with a connecting seat for connecting to the drive device. The connecting seat is provided with a non-circular shaft hole that matches the output shaft end of the drive device, and a guide groove for the output shaft is provided on one side of the non-circular shaft hole.

[0012] A connecting protrusion is provided around the central axis of the positioning sleeve end face at the drive end, and both ends of the connecting rod are sleeved on the connecting protrusion.

[0013] The flip cover has rotating arms at both ends, and the positioning protrusions of the driving end and the driven end are disposed at the ends of the rotating arms.

[0014] The active and passive flip covers are symmetrically arranged at the waste disposal port.

[0015] The active and passive flip covers are asymmetrically positioned at the waste disposal opening; and the width of the active flip cover is greater than that of the passive flip cover.

[0016] The output shaft of the drive device of this utility model is directly coaxially connected to one end of the rotating shaft of one of the flip covers. The two flip covers are synchronously linked by a connecting rod or chain. At the same time, this utility model is pivotally connected to the shaft hole on the inner wall of the garbage disposal port through a positioning protrusion ring and a positioning sleeve. A connecting seat for connecting the drive device is provided on the outer end face of the positioning sleeve at the active flip cover drive end. A guide groove for the output shaft is opened on one side of the non-circular shaft hole on the connecting seat. It has the characteristics of compact structure and convenient assembly.

[0025] like Figure 1-8 As shown, a drive structure for a double-lid trash can includes a base 1, on which a trash inlet 11 is provided. Two flip covers 2 are provided at the trash inlet 11. When the two flip covers 2 are joined together, they match the shape of the trash inlet 11. The two ends of the flip covers 2 are bent downward to form rotating arms 20. The rotating arms 20 at both ends of the two flip covers 2 are pivotally connected to the inner wall of the trash inlet 11 through a driven end 32 and a driving end 31, respectively. A drive device 3 is provided on the outer side of the trash inlet on the base 1. The two flip covers 2 are an active flip cover 21 and a driven flip cover 22, respectively. The output shaft 30 of the drive device 3 is directly coaxially connected to the driving end 31 of the active flip cover 21.

[0026] Both the driving end 31 and the driven end 32 include a positioning protrusion 51 and a positioning sleeve 52. The positioning protrusion 51 is located at the end of the rotating arm 20. A shaft hole 12 is provided on the inner wall of the garbage disposal port 11 corresponding to the position of the positioning protrusion 51. The positioning protrusion 51 passes through the shaft hole 12. The positioning sleeve 52 is sleeved on the positioning protrusion 51 on the other side of the shaft hole 12, so that the flip cover 2 is pivotally connected to the inner wall of the garbage disposal port 11. The positioning protrusion 51 also has an axially protruding latch 53. The positioning sleeve 52 has a latch hole 54 that cooperates with the latch 53. The latch 53 is engaged in the latch hole 54 to axially position the positioning protrusion 51 and the positioning sleeve 52. The positioning sleeve 52 has a positioning ring 55 that cooperates with the positioning protrusion 51. The positioning ring 55 cooperates with the positioning protrusion 51 to ensure that the positioning protrusion 51 and the positioning sleeve 52 are coaxial.

[0027] The driving end 31 of the active flip cover 21 and the driving end 31 of the driven flip cover 22 are connected by a connecting rod 4. A connecting protrusion 41 is provided on the periphery of the central axis of the end face of the positioning sleeve 52 of the driving end 31. The two ends of the connecting rod 4 are sleeved on the connecting protrusion 41. The phase difference between the two connecting protrusions 41 on the two driving ends 31 is between π / 2 and π. When the active flip cover 21 rotates, it drives the driven flip cover 22 to rotate synchronously in the opposite direction through the connecting rod 4.

[0028] The outer end face of the positioning sleeve 52 of the drive end of the active flip cover 21 is provided with a connecting seat 56 for connecting to the drive device. The connecting seat 56 is provided with a non-circular shaft hole 57 that matches the output shaft 30 end of the drive device. A guide groove 58 for the output shaft is provided on one side of the non-circular shaft hole 57.

[0029] The two ends of the flip cover 2 of this utility model, the driving end 31 and the driven end 32, are pivotally connected to the shaft hole 12 of the garbage disposal port 11 through the positioning protrusion ring 51 and the positioning sleeve 52. The positioning protrusion ring 51 and the positioning sleeve 52 are engaged to provide axial positioning. In addition, the output shaft 30 of the driving device 3 enters the non-circular shaft hole 57 through the guide groove 58, so that the driving device 3 and the driving end 31 can be quickly coaxially connected, making the whole assembly very convenient.

[0030] In addition, the output shaft of the drive device of this utility model directly drives one of the flip covers, and the two flip covers are synchronously linked through a connecting rod; by setting the phase difference between the two connecting protrusions 41 connected to both ends of the connecting rod 4 on the positioning sleeve 52 between π / 2 and π, it is ensured that the two flip covers rotate in opposite directions during operation, and the transmission mechanism is simpler and more compact; the active flip cover 21 and the driven flip cover 21 shown in the attached figure of this embodiment are about the same width and are symmetrically arranged at the garbage disposal port 11; according to actual needs, the active flip cover 21 and the driven flip cover 21 can also be of different widths and are arranged in an asymmetrical structure at the garbage disposal port 11; since the active flip cover (21) is directly connected to the drive device, the width of the active flip cover 21 is greater than that of the driven flip cover 22, which reduces the transmission resistance of the connecting rod. This utility model has the characteristics of compact structure and convenient assembly.
