Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of garbage cans, concretely relates to a single top rod component force transmission's double open cover structure and garbage can thereof. BACKGROUND

[0002] Garbage cans as indispensable tools in daily life are widely used in various scenes. In order to prevent the peculiar smell of garbage from being emitted from the garbage can, the existing garbage cans are usually provided with a can cover, and when garbage is not needed to be put in, the can cover covers the putting opening of the garbage can, so that the barrel cavity of the garbage can forms a closed space. In the flip-top garbage can, the double-open cover garbage can has a smaller active space of the can cover than the single-open cover, and is more popular than the single-open cover garbage can. However, most of the existing double-open cover garbage cans are controlled by double-top rod mechanisms to open and close the can cover, and the double-top rod mechanism exerts force on the bottom of the garbage can, which increases the volume of the component force structure, not only increases the occupied space of the component force structure in the garbage can, but also increases the material cost.

[0003] In the prior art, such as the patent document with the announcement number CN221955077U, a novel garbage can is disclosed, which drives the eight-shaped long rod to open to both sides through the rectangular sliding plate, and then makes the can cover slide and open to both sides. However, when the rectangular sliding plate drives the eight-shaped long rod, force is exerted on the bottom of the garbage can, which causes the rectangular long rod and the eight-shaped long rod to occupy a large space, not only reduces the effective volume of the garbage can, but also increases the material cost. SUMMARY

[0004] In view of the problems in the prior art, the utility model provides a single top rod component force transmission's double open cover structure and garbage can thereof, which drives the rocker arm hinged to the upper part of the barrel through a single top rod, and simultaneously drives two can covers to open and close at the same time through the component force transmission mode of the rocker arm at the top of the garbage can, reduces the volume of the component force structure, improves the space utilization rate of the garbage can, and reduces the material cost.

[0005] The utility model is implemented as follows: a single top rod component force transmission's double open cover structure is arranged on a barrel; the top of the barrel is provided with a barrel opening, and a can cover is hinged to the barrel opening; the can cover is provided with two can covers, which are symmetrically arranged on both sides of the barrel opening and cover the barrel opening; the utility model further comprises a rocker arm, which is hingedly connected to the upper part of the barrel in a clasp-like manner; the rocker arm comprises a rocker arm main body, two transmission rods are arranged at the two ends of the rocker arm main body, and the two transmission rods are respectively in transmission connection with the two can covers; the error between the rocker arm and the can cover is amplified due to the increase of the distance between the rocker arm and the can cover, the error between the two, such as the positional deviation caused by the angle error, is reduced when the distance between the rocker arm and the can cover is short; the error between the can covers is reduced, the synchronism between the can covers is improved, and the opening and closing of the can covers are more stable.

[0006] The middle end of the rocker arm body is hinged with a top rod, the other end of the top rod extends to the bottom of the barrel body and is connected with the pedal transmission; wherein the length of the top rod is greater than the length of the transmission rod; when the pedal moves up and down, the top rod drives the rocker arm body to swing around the hinge, and the two transmission rods synchronously drive the two side barrel lids to open or close. The single top rod drives the rocker arm to swing, and then the swing arm simultaneously drives the two barrel lids to open by the partial force on the barrel body, which simplifies the double-opening lid structure and reduces the size of the partial force structure, improves the effective volume of the garbage can, and further improves the space utilization rate of the garbage can and reduces the material cost of the garbage can.

[0007] Preferably, the upper and lower ends of the transmission rod are respectively provided with first and second hinge holes which are perpendicular to each other, the first hinge hole is hinged with the barrel lid, and the second hinge hole is hinged with the rocker arm body. Since the rocker arm body simultaneously drives the double barrel lids to open, when the rocker arm body swings upward, the barrel lids need to open to both sides, that is, the hinge shaft of the rocker arm is perpendicular to the hinge shaft of the barrel lid. The first and second hinge holes which are perpendicular to each other make the first hinge hole correspond to the hinge shaft of the barrel lid, and the second hinge hole correspond to the hinge shaft of the rocker arm, so that the transmission rod can simultaneously rotate around the rocker arm and the barrel lid when driving the barrel lid to open or close, improving the fluency of the rocker arm driving the barrel lid to open or close.

[0008] Specifically, the two ends of the first and second hinge holes gradually increase from inside to outside, forming a conical hole part in the shape of a trumpet mouth, so that the transmission rod can swing around the center line of the first and second hinge holes. When the rocker arm swings up and down, since the rocker arm makes a circular motion, the position of the second hinge hole not only moves up and down, but also moves forward and backward; similarly, the position of the first hinge hole not only moves up and down, but also moves left and right. When the second hinge hole moves forward and backward, the transmission rod swings around the center line of the first hinge hole, and when the first hinge hole moves left and right, the transmission rod swings around the center line of the second hinge hole. The conical hole part makes the transmission rod adapt to the position change of the first and second hinge holes by swinging, further improving the fluency of the barrel lid opening or closing.

[0009] Specifically, the two ends of the rocker arm body extend along the side wall of the barrel body, forming a hinge part, so that the rocker arm is in the shape of U; the end of the hinge part is hinged with the barrel body, so that the hinge point of the rocker arm and the barrel body is away from the second hinge hole, and when the rocker arm swings, the movement trajectory of the second hinge hole tends to be a straight line, thereby reducing the partial force of the transmission rod in addition to the vertical direction, and making the transmission rod more easily open the barrel lid.

[0010] Preferably, the barrel body is provided with a slidingly connected locking unit, and the rocker arm body is also provided with a hook portion matched with the locking unit. When the barrel cover is opened, the locking unit is connected with the hook portion through sliding, so that the barrel cover is kept open. When it is necessary to continuously put garbage into the garbage can, the open barrel cover reduces the number of times of opening the barrel cover, thereby reducing the wear caused by frequent opening of the garbage can, prolonging the service life of the garbage can, and making the garbage can applicable to more use scenarios.

[0011] Specifically, the rocker arm body is also provided with a limiting portion, and the barrel body is provided with a limiting hole matched with the limiting portion. When the locking unit is connected with the hook portion, the limiting portion is inserted into the limiting hole. When the locking unit is connected with the hook portion, a transverse pushing force is generated on the rocker arm, and the rocker arm is deformed transversely, which may cause the hook portion to fail to be connected with the locking unit. The insertion of the limiting portion into the limiting hole can prevent the rocker arm from being deformed transversely, so as to ensure the reliability of the connection between the locking unit and the hook portion.

[0012] Preferably, one side of the top rod bottom is provided with a buffer, and the top rod is provided with a buffer portion matched with the buffer. When the top rod descends, the buffer portion abuts against the buffer end of the buffer. Since the gravity acting on the barrel cover is used as a power source when the barrel cover is closed, a large impact force is generated on the barrel cover at the moment of closing, which reduces the service life of the barrel cover. Since the top rod descends when the barrel cover is closed, the buffer is used for buffering when the top rod descends, thereby buffering when the barrel cover is closed, reducing the impact on the barrel cover when the barrel cover is closed, and prolonging the service life of the barrel cover.

[0013] Preferably, the rocker arm is made of sheet metal. Sheet metal has better rigidity than ordinary plastic, which reduces the risk of deformation of the rocker arm when it swings, thereby ensuring the synchronization of the opening and closing of the barrel cover.

[0014] A garbage can applying the single-top-rod component force transmission double-opening-cover structure,

[0015] Specifically, the barrel body is provided with a pedal at the bottom, and the pedal is hingedly connected to the lateral side of the barrel body. A rotating shaft is also arranged in the barrel body and is horizontally hinged to the bottom of the barrel body. One end of the rotating shaft extends out of the barrel body and is upwardly folded to abut against the pedal, and the other end is in transmission connection with the top rod. Compared with a common pedal, the rotating shaft requires less space for driving the top rod, thereby increasing the volume of the garbage can. A handle is also arranged on the barrel body and is symmetrically arranged on the front and rear sides of the barrel body. A roller is also arranged on the bottom surface of the barrel body.

[0016] The utility model discloses a beneficial effect:

[0017] The utility model provides a kind of double-lid structure of single top rod component force transmission and its garbage can, by single top rod drive hinged in the rocker of barrel top, again by rocker on barrel partial force transmission mode, simultaneously drive two barrel lids open and close simultaneously, simplify double-lid structure and reduce the volume of component force structure, improve the effective volume of garbage can, to improve the space utilization of garbage can and reduce the material cost of garbage can.

DETAILED DESCRIPTION

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] like Figures 1-6 As shown, a double-lid structure with a single-push rod force-shaping transmission is provided on a barrel body 1. The top of the barrel body 1 is provided with a barrel opening, and a barrel lid 2 is hinged to the barrel opening. There are two barrel lids 2, symmetrically arranged on both sides of the barrel opening and covering the barrel opening. It also includes a rocker arm 3, which is hinged to the upper part of the barrel body 1 in a hugging shape. The rocker arm 3 includes a rocker arm body 34, and each end of the rocker arm body 34 is provided with a transmission rod 5. The two transmission rods 5 are respectively connected to the barrel lids 2 on both sides. The error between the rocker arm 3 and the barrel lid 2 will be amplified as the distance between the rocker arm 3 and the barrel lid 2 increases. When the distance between the rocker arm 3 and the barrel lid 2 is short, the error between the two is reduced, such as the positional offset caused by the angle error. This reduces the error between the barrel lids 2, improves the synchronization between the barrel lids 2, and makes the opening and closing of the barrel lids 2 more stable.

[0031] In this embodiment, the upper and lower ends of the transmission rod 5 are respectively provided with a first hinge hole 51 and a second hinge hole 52 that are perpendicular to each other. The first hinge hole 51 is hinged to the bucket lid 2, and the second hinge hole 52 is hinged to the rocker arm body 34. Since the rocker arm body 34 drives both bucket lids 2 to open simultaneously, when the rocker arm body 34 swings upward, the bucket lids 2 need to open to both sides, that is, the hinge axis of the rocker arm 3 is perpendicular to the hinge axis of the bucket lids 2. The mutually perpendicular first hinge hole 51 and second hinge hole 52 make the first hinge hole 51 correspond to the hinge axis of the bucket lids 2, and the second hinge hole 52 correspond to the hinge axis of the rocker arm 3, so that when the transmission rod 5 drives the bucket lids 2 to open or close, it can rotate around the rocker arm 3 and the bucket lids 2 simultaneously, improving the smoothness of the rocker arm 3 driving the bucket lids 2 to open or close.

[0032] Specifically, the two ends of the first and second hinge holes 51 and 52 gradually increase from inside to outside, forming a conical hole part 53 in the shape of a bell mouth, so that the transmission rod 5 can swing around the center line of the first and second hinge holes 51 and 52. When the rocker arm 3 swings up and down, due to the circular motion of the rocker arm 3, the position of the second hinge hole 52 will not only move up and down, but also move forward and backward; similarly, the position of the first hinge hole 51 will not only move up and down, but also move left and right. When the second hinge hole 52 moves forward and backward, the transmission rod 5 swings around the center line of the first hinge hole 51, and when the first hinge hole 51 moves left and right, the transmission rod 5 swings around the center line of the second hinge hole 52. The conical hole part 53 allows the transmission rod 5 to adapt to the position change of the first and second hinge holes 51 and 52 through swinging, further improving the smoothness of the opening or closing of the bucket cover 2.

[0033] The middle end of the rocker arm body 34 is hingedly connected to a top rod 4, the other end of the top rod 4 extends to the bottom of the bucket body 1 and is in transmission connection with the pedal 11; wherein the length of the top rod 4 is greater than the length of the transmission rod 5; when the pedal 11 moves up and down, the top rod 4 drives the rocker arm body 34 to swing around the hinge, and the two transmission rods 5 synchronously drive the two bucket covers 2 to open or close. By driving the rocker arm 3 to swing through a single top rod 4, and then driving two bucket covers 2 to open at the same time through the force of the swinging arm on the upper part of the bucket body, the double-opening cover structure is simplified and the size of the force distribution structure is reduced, the effective volume of the garbage can is improved, and the space utilization rate of the garbage can is improved and the material cost of the garbage can is reduced.

[0034] In this embodiment, one side of the bottom of the top rod 4 is provided with a buffer 7, and the top rod 4 is provided with a buffer part 41 matched with the buffer 7, and when the top rod 4 descends, the buffer part 41 abuts against the buffer end of the buffer 7. Since the gravity acting on the bucket cover 2 is used as the power source when the bucket cover 2 is closed, a large impact force is generated at the moment of closing of the bucket cover 2, which reduces the service life of the bucket cover 2. Since the top rod 4 descends when the bucket cover 2 is closed, the buffer 7 is used to buffer the descent of the top rod 4, thereby buffering the closing of the bucket cover 2, reducing the impact on the closing of the bucket cover 2, and improving the service life of the bucket cover 2.

[0035] In this embodiment, the rocker arm 3 is made of sheet metal, which has better rigidity than ordinary plastic, reducing the risk of deformation of the rocker arm 3 when it swings, thereby ensuring the synchronization of the opening or closing of the bucket cover 2.

Compared with the common pedal, the rotating shaft 13 requires smaller space for driving the top rod 4, thereby improving the volume of the garbage can. A handle 12 is further arranged on the barrel body 1, the handle 12 being symmetrically arranged on the front and rear sides of the barrel body 1; and a roller is further arranged on the bottom surface of the barrel body 1.
