Description

Technical Field

[0001] The utility model relates to the technical field of trash can structures, in particular to a synchronously opened and closed trash can cover structure and the trash can. Background Art

[0002] Conventional trash cans are lidless trash cans and single-lid trash cans. These types of trash cans have the advantages of being cheap, simple in structure, and not easy to break. However, the former easily produces and emits a lot of garbage odor, affecting the living experience, while the latter usually requires users to bend down to manually open the flip cover, or use a foot-operated linkage mechanism to open the lid, which some users find troublesome. In addition, the single-lid lid is high when flipped up, occupying a larger activity space.

[0003] Therefore, many manufacturers have improved the trash can and designed a smart trash can with double flip lids. Usually, the flip lids can be opened automatically when the user approaches, which is very convenient and the flip lids occupy less space for activities. This type of trash can needs to open and close the two flip lids at the same time, which involves the synchronization problem of the flip lids. A common design is to assign a drive mechanism to each flip lid and use a control system to control the synchronization rate of the two drive mechanisms. However, the cost of this design is high, and the aging, wear and tear of the mechanism and the coordination of the control system are prone to synchronization errors. Other trash cans use linkage mechanisms to achieve the synchronous action of the two flip lids. For example, the patent document with announcement number CN217893965U provides a double-opening structure for a trash can. This solution sets many gear structures in the trash can for transmission to achieve the driving linkage of the double opening lids. However, this design leads to a relatively complex internal active mechanical structure, many parts, easy to make mistakes, low fault tolerance, and difficult to maintain; and the sizes of each gear are various, and the cost of coordination and production is high.

[0004] Therefore, there is an urgent need to provide a synchronously opening and closing bucket cover structure and a trash can thereof to solve the above-mentioned technical problems. Summary of the invention

[0005] In view of the problems in the related art, the utility model provides a synchronously opened and closed bucket cover structure and a garbage can thereof, which has good synchronization effect, simple structure and low production cost.

[0006] The utility model is achieved in this way:

[0007] A barrel cover structure for synchronous opening and closing, applied to a trash can, comprises two flip covers arranged at opposite sides of each other, the flip covers comprising a cover body and an arm portion extending away from the cover body; the two arm portions are respectively pivotally connected with auxiliary gears, a driving gear is arranged between the two auxiliary gears, and a driving unit for driving the driving gear to rotate; and further comprises two transmission racks, the two transmission racks are arranged symmetrically around the driving gear;

[0008] The transmission rack includes a first transmission part and a second transmission part fixedly connected as one; the transmission rack is connected to the driving gear through the first transmission part, and is connected to the auxiliary gear through the second transmission part; wherein the second transmission part is a frame-shaped structure, including a first frame bar and a second frame bar, and the first frame bar and the second frame bar are arranged on both sides of the auxiliary gear oppositely; when an auxiliary gear is connected with the first frame bar of the transmission rack on its side, another auxiliary gear is connected with the second frame bar of the transmission rack on its side. That is, the same auxiliary gear can only be connected with the first frame bar or the second frame bar of the same transmission rack at the same time.

[0009] The frame structure includes a fully enclosed frame and a semi-open frame. The frame structure of the transmission rack cooperates with the auxiliary gear as a limiting mechanism, so that the transmission rack as a whole can only move horizontally under the cooperation of the driving gear and the auxiliary gear.

[0010] The centrally symmetrical setting is conducive to using the same set of molds for the transmission rack and auxiliary gear for production, thereby reducing mold opening costs.

[0011] The opening / closing of the flap is realized by making the driving gear rotate forward / reverse; the synchronous opening and closing of the two flaps of the trash can is realized by setting the matching connection of the transmission rack, the driving gear, the auxiliary gear and the driving unit.

[0012] As a further optimization of the above scheme, the auxiliary gear includes a convex tooth portion; the convex tooth portion is arranged at a section of the circumferential side of the auxiliary gear; a plurality of evenly distributed convex teeth are arranged along the convex tooth portion; the convex tooth portion is transmission-connected to the first frame bar or the second frame bar.

[0013] By adjusting the number of convex teeth and the proportion of the convex teeth on the peripheral side of the auxiliary gear, the rotation amplitude of the auxiliary gear can be adjusted, and then the rotation amplitude of the entire flip cover can be adjusted. For example, the proportion of the convex teeth on the peripheral side of the auxiliary gear is 1 / 2 or 1 / 3.

[0014] As a further optimization of the above solution, the second transmission portion extends along the first frame bar, or along the second frame bar to form the first transmission portion.

[0015] As a further optimization of the above solution, a rotating shaft is provided on the support arm; a fixed limiting opening for the rotating shaft to pass through is provided on the trash can; and the rotating shaft is cooperatively connected with one of the auxiliary gears.

[0016] An auxiliary gear, under the action of a transmission rack, drives the rotating shaft and the corresponding flip cover to rotate around the limiting opening.

[0017] As a further optimization of the above scheme, a connecting platform protruding outward is provided at the end of the rotating shaft; a limiting opening is provided at the center of the auxiliary gear; the limiting opening is non-circular; the connecting platform and the limiting opening cooperate with each other so that the rotating shaft and the auxiliary gear can be detachably connected.

[0019] When the flip cover is opened, the transmission rack moves outward until the limiting boss presses against / jams the auxiliary gear, and the flip cover stops rotating.

[0020] As a further optimization of the above solution, the driving unit is a motor, or a mechanical linkage mechanism.

[0021] The mechanical linkage mechanism can be a conventional pedal linkage mechanism or the like.

[0022] The utility model also provides a trash can, which applies the above-mentioned synchronous opening and closing bucket cover structure.

[0023] As a further optimization of the above solution, the trash can includes a barrel body and a barrel head, and the barrel body and the barrel head are cooperatively connected; the driving gear, the auxiliary gear and the transmission rack are all arranged inside the barrel head; the flip cover is cooperatively connected with the barrel head.

[0024] As a further optimization of the above solution, at least two raised support platforms are provided on the inner side of the barrel head; at least two of the support platforms are horizontally distributed; and the transmission rack is placed above the support platforms.

[0025] The beneficial effects are as follows:

[0026] The utility model provides a synchronously opening and closing lid structure and a trash can thereof, which realizes the synchronous opening and closing of the two lids of the trash can by setting a linkage mechanism composed of a driving gear, an auxiliary gear, a transmission rack and a driving unit inside the trash can, and the opening and closing of the lids can be realized by changing the forward / reverse rotation of the driving gear. Compared with the prior art, the solution provided by the utility model is simple in structure, efficient, easy to maintain, and not easy to damage. At the same time, the transmission rack is centrally symmetrically arranged, which is conducive to using the same set of molds for production and reducing mold opening costs.
