Referring to fig. 1 and 2, a pull-cord mechanism 200 according to a preferred embodiment of the present invention is used in a dustbin 100, and the pull-cord mechanism 200 includes: a reel 210; a pulling rope 220 wound around the reel 210, an end of the pulling rope 220 being connected to the cover 110 of the dustbin 100; and a driving assembly 230 for driving the reel 210 to rotate to release or wind the pull cord 220; wherein the cover 110 is gradually closed in response to the release of the pull cord 220 or gradually opened in response to the winding of the pull cord 220.

According to the invention, the pull rope mechanism 200 is arranged, the pull rope 220 of the pull rope mechanism 200 is connected with the box cover 110, and the pull rope 220 is driven by the driving assembly 230 to be released or wound up, so that the box cover 110 is controlled to be closed or opened, and the mechanism can be directly applied to the existing flip type dustbin 100, and the input cost is effectively reduced; in addition, by providing the reel 210 to wind the pull cord 220, the pull cord mechanism 200 is smaller in overall size, convenient to use in a limited space, and also capable of enabling the release and winding of the pull cord 220 to be more orderly.

Further, the pulling rope mechanism 200 is provided at the rear upper side of the dustbin 100.

The worm wheel 232 is rotatably installed in the second housing 231 and engaged with the worm, the worm wheel 232 is provided with a protrusion 2321 protruding from the second housing 231 along an axial direction thereof, the reel 210 is fixed to the protrusion 2321 and is coaxially disposed with the worm wheel 232, and an end of the pull cord 220 not connected to the case cover 110 is fixed to the reel 210. When the driving motor rotates, it can drive the worm and the worm wheel 232 to rotate, and further drive the reel 210 to synchronously rotate, so as to drive the winding to wind or release under the rotation of the reel 210.

However, with the above-described structure, when the cord mechanism 200 winds up the cord 220, there is a case where the case cover 110 collides against the first case 240, thereby causing damage to the first case 240. In order to avoid the above situation, the pull rope mechanism 200 includes a limiting component 250 fixed on the pull rope 220, where the limiting component 250 is located outside the first housing 240, and the limiting component 250 is adapted to abut against the first housing 240 after the pull rope 220 is wound to a preset length, so as to prevent the pull rope 220 from being wound continuously, further control the winding degree of the pull rope 220, and prevent the first housing 240 from being collided due to the overlarge opening angle of the case cover 110. In this embodiment, the stop assembly 250 is disposed at an end of the pull cord 220 that is attached to the lid 110.

When the pull cord 220 is wound, the limiting assembly 250 abuts against the third abutting piece 2622 of the wire tube 262, so that the wire tube 262 moves from the extended state to the contracted state, at this time, the blocking piece 2624 gradually moves towards one end of the second elastic piece 263 to drive the other end of the second elastic piece 263 to contact with the mounting block 2611, and as the blocking piece 2624 gradually abuts against the second elastic piece 263, the second elastic piece 263 gradually compresses along with the contraction of the wire tube 262 and provides a reaction force for driving the wire tube 262 to move towards the extended state; when the pull cord 220 is released, the limiting assembly 250 releases the abutment of the wire tube 262, and the wire tube 262 is switched from the contracted state to the extended state under the rebound action of the second elastic member 263.

Further, the pull cord mechanism 200 further includes a rotating block 280 rotatably disposed in the first accommodating cavity 241, and the rotating block 280 is located on the retracting path of the pull cord 220. The rotating block 280 has a first rotating state and a second rotating state, the rotating block 280 is adapted to switch from the first rotating state to the second rotating state after the pull rope 220 is released to a preset length, and the first sensing component 270 senses the second rotating state and drives the driving component 230 to stop working.

The first sensing assembly 270 includes a second sensing switch 272, and the second sensing switch 272 is specifically a micro switch, which corresponds to a rotating block 280. In the releasing process, the pull rope 220 can change the position along with the gradual turning and closing of the case cover 110, and drives the rotating block 280 to gradually switch from the first rotating state to the second rotating state, when the rotating block 280 is in the second rotating state, the rotating block can be abutted against the second inductive switch 272 and trigger the second inductive switch 272, so that the case cover 110 in the completely closed state is sensed, and the second inductive switch 272 can transmit a trigger signal to the driving assembly 230 to drive the driving assembly 230 to stop working.

The plurality of sensing pieces 292 are provided at equal intervals along the circumferential direction of the reel 210 to improve the position recognition accuracy of the reel 210.
