DETAILED DESCRIPTION

[0030] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0031] Reference Figure 1 、 Figure 2 A trash can with an automatically opening and closing bottom door includes a box body 1, a top door 11 installed on the top of the box body, hanging ears 12 installed on both sides of the top of the box body 1, a bottom door 13 installed at the bottom of the box body 1, and an automatic opening and closing structure 2 installed on the inner side wall of the box body 1.

[0032] The above structure can be used to throw garbage into the room through the top door 11 , tilt the lifting lugs 12 , and dump the garbage out through the bottom door 12 .

[0033] Reference Figure 2 The bottom door 13 is connected to the box body 1 through a torsion spring hinge 14 , and the elastic force of the torsion spring hinge 14 just overcomes the dead weight of the bottom door 13 .

[0034] The above-mentioned structure can realize that the bottom door can be automatically closed after being tilted.

[0035] Reference Figure 3 , wherein the automatic opening and closing structure 2 includes a push rod 21 that can be movably extended to the outside of the bottom of the box body 1, a spring 22 sleeved on the push rod 21, a guide sleeve 23 sleeved on the push rod 21, a driving gear 25 installed on the right side of the push rod 21, a shaft 24 passing through the middle of the driving gear 25, and the shaft 24 is connected to the box body 1 through a bearing, a driven gear 27 meshing with the driving gear 25, a driven shaft 26 passing through the middle of the driven gear 27, and the driven shaft 26 is connected to the box body 1 through a bearing, and one end of the driven shaft 26 is keyed to a half-open sleeve 28.

[0036] Reference Figure 5 The push rod 21 includes an upper limit position 211, a lower limit position 212, and a shift rod 213 hinged to the push rod 21, and the shift rod 213 rotates 80° counterclockwise around the hinge portion.

[0037] Reference Figure 3 , where the number of teeth of the driving gear 25 is equal to 2.5 times the number of teeth of the slave gear.

[0038] Reference Figure 3 One side of the driving gear 25 is provided with five rectangular protrusions 251 , and the rectangular protrusions 251 are evenly distributed on the end surface of the driving gear 25 .

[0039] Through the above arrangement, it can be achieved that every time the trash can falls to the ground, the push rod drives the lever, which drives the driving gear to rotate 1 / 5, drives the driven gear to rotate 1 / 2, and the driven gear drives the coaxial half-open sleeve to rotate 1 / 2.

[0040] Reference Figure 6 , wherein the half-open sleeve 28 is provided with an opening portion 281 and a closing portion 282 .

[0041] Reference Figure 7 , wherein a lock hook 131 is fixedly welded on the bottom door 13 .

[0042] The above structure can be used to achieve the following: when dumping garbage, you only need to lift the garbage bin and place it on the bottom plate of the transportation vehicle and then lift it again. The locking device will automatically open, and the gravity of the garbage will overcome the elastic force of the torsion spring on the bottom door. The bottom door will open and the garbage will be dumped. After the dumping is completed, the torsion spring closes the bottom door, and the locking device will be locked when the garbage bin is on the ground.

[0043] Working principle:

[0044] When the trash can is placed on the ground, the push rod 21 is in the jacking state. Figure 4The closing portion 282 of the half-open sleeve 28 is at the bottom, cooperating with the bottom door lock hook 131, and the bottom door is in a locked state. When the garbage bin is full and needs to be dumped, the garbage bin is lifted up, and the push rod 21 is reset under the action of the spring 22 and extends out of the bottom of the garbage bin. Since the reset action of the ratchet mechanism does not drive the gear action, the garbage bin is in a locked state in the air and will not open. After the garbage bin is lifted above the dumping vehicle, it needs to fall to the bottom plate of the vehicle. During the falling process, the push rod 21 is lifted up again, which will drive the lever 213 to turn the drive gear 25 to rotate 1 / 5. The driving gear 25 drives the driven gear 27 to rotate 1 / 2, and the driven gear 27 drives the coaxial half-open sleeve 28 to rotate 1 / 2. The closing part 282 of the half-open sleeve 28 rotates upward, and the opening part 281 rotates downward, disengaging from the lock hook 131, and the trash can is lifted again. The gravity of the trash will overcome the torsion of the torsion spring hinge 14 to realize the dumping of the trash. After the dumping is completed, the torsion spring hinge 14 closes the bottom door. When it is placed on the ground, the above action is performed again, and the closing part 282 of the half-open sleeve 28 and the lock hook 131 are locked.

[0045] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by persons skilled in the art should fall within the scope of protection defined by the claims of the present invention.
