[0001] The utility model belongs to the technical field of daily necessities and relates to a garbage bin. Background Art

[0002] In daily life, people produce all kinds of garbage all the time. For the convenience of use at home, household trash cans are generally small in size. When garbage needs to be transported, large trash cans are used. For example, a mobile trash can disclosed in a patent document (application number: 201510218415.0) includes a box body, a handle is provided on the side of the box body, a roller is provided at the bottom of the box body, a positioning body is provided on the roller, a cover body is provided on the top of the box body, and a handle is provided on the cover body. In the trash can, the cover body is the box cover of the trash can, and the rear side of the top plate of the trash can is hinged to the box body. When in use, the box cover is pulled up and the box cover is swung upward around its rear side to open the box cover. The trash can has the following shortcomings during use: the box cover of the large trash can is heavy, and the box cover opening method needs to overcome almost all the weight of the box cover before the box cover can be lifted up and opened, which will make the process of opening the box cover more laborious. Moreover, the lid of the trash can usually be opened at a certain angle to throw the garbage into the trash can. Therefore, when throwing the garbage, one needs to lift the lid with one hand and throw the garbage into the box with the other hand. At this time, it is also laborious to keep lifting the lid with one hand. Therefore, the trash can has the problem of being laborious to use. Summary of the invention

[0003] The purpose of the utility model is to solve the above problems in the existing technology and propose a garbage bin to solve the problem that the existing large garbage bins are relatively laborious to use, while ensuring the stability of the opening and closing process of the lid of the large garbage bin.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a garbage bin, comprising a box body and a box cover, the box body having a left side plate and a right side plate, characterized in that the box cover comprises a cover body and two swing arms respectively connected to the left and right side edges of the cover body, the cover body having a top plate body with a top surface protruding upward and an arc-shaped cross-section along the front-to-back direction, the lower ends of the two swing arms are respectively hinged to the outer side walls of the left and right plates, and the swing arms can swing backwards with the box cover to open the box cover; the top of the left side plate has a protruding plate body 1 with an arc-shaped upper edge, the top of the right side plate has a protruding plate body 2 with an arc-shaped upper edge, and the position of the top plate near its front side edge has a guide surface 1 that is in contact with or close to the inner side wall of the protruding plate body 1 and a guide surface 2 that is in contact with or close to the inner side wall of the protruding plate body 2.

[0005] The top plate of the lid of the trash can is set to an upwardly protruding structure, and the cross section of the top plate along the front-to-back direction is arc-shaped, so that the upwardly concave space on the lower side of the lid can form a circumvention with the lid, so that the swing arm can swing backward with the lid to open the lid. Since the lid is also provided with a swing arm, the weight of the lid is mainly supported by the swing arm during the opening process, and the user only needs to apply a force to drive the lid to rotate, so that the lid can be opened more labor-saving and convenient. At the same time, when the lid only needs to be opened to a certain angle to throw away the garbage, the swing arm still supports the lid. At this time, the operator only needs to provide a force to keep the lid fixed with one hand, and throw the garbage into the box with the other hand, so it will also be more labor-saving.

[0006] This trash can is a large trash can, so its lid is large in size and heavy in weight, so it is necessary to consider the stability of the lid during opening and closing. In view of this, this trash can sets a guide surface 1 and a guide surface 2 on the top plate near its front side, and the guide surface 1 and the guide surface 2 are respectively abutted against or close to the inner side walls of the raised plate 1 and the raised plate 2, so that the front side of the lid is limited between the raised plate 1 and the raised plate 2, so that the lid of a larger size can be guided during opening or closing, avoiding the left and right shaking of the lid, improving the smoothness of the lid opening or closing process, and making the lid opening and closing process more convenient and labor-saving.

[0007] In the above-mentioned trash can, the top plate has a reinforcing plate arranged along the left-right direction on the lower side surface near the front side thereof, the left end surface of the reinforcing plate is the guide surface 1, and the right end surface of the reinforcing plate is the guide surface 2. The two ends of the reinforcing plate are respectively formed with the guide surface 1 and the guide surface 2, which can make processing more convenient. Moreover, when opening the lid, the operator's hand is usually required to act on the front side of the top plate of the lid. At this time, by arranging the reinforcing plate arranged along the left-right direction on the lower side surface of the front side of the top plate, the front side of the top plate has a higher structural strength, avoiding structural deformation, and improving the service life of the trash can.

[0008] In the above-mentioned trash bin, the middle parts of the outer side walls of the left and right panels are fixedly connected with hinge seats, the hinge seats have a columnar hinge part, the lower end of the swing arm has a cylindrical sleeve part, and the sleeve part is rotatably sleeved on the hinge part. The hinge part is provided on the hinge seat, and the sleeve part is provided at the lower end of the swing arm, and the sleeve part is rotatably sleeved on the hinge part, so that the installation of the swing arm is realized, and the installation is relatively stable, which can improve the stability of the swing arm during the swinging process.

[0009] In the above-mentioned trash can, the hinge seat also has an annular positioning part arranged around the outer periphery of the hinge part, and a torsion spring is sleeved on the annular positioning part, one end of the torsion spring is fixed on the hinge seat, and the other end of the torsion spring is against the swing arm. The annular positioning part can facilitate the installation of the torsion spring. When the lid needs to be closed, the torsion spring can make the swing arm have an upward swinging tendency after the swing arm swings backward. Therefore, the torsion spring can provide a force to assist the lid to swing upward, making the process of closing the lid more labor-saving. In addition, during the process of opening the lid, the torsion spring can also play a buffering role, so that the lid can be opened stably, avoiding the lid from falling down instantly and colliding with the box body quickly, making the process of opening the lid more convenient.

[0010] In the above-mentioned trash can, the left and right sides of the top plate body are provided with side panels extending downward, the raised plate body 1 is located on the inner side of the side panel body at the left side of the top plate body, the raised plate body 2 is located on the inner side of the side panel body at the right side of the top plate body, and the upper end of the swing arm is fixedly connected to the lower edge of the side panel body on the same side. By providing the side panel body, the connection between the swing arm and the box cover can be facilitated. At the same time, the raised plate body 1 and the raised plate body 2 of the box body are located on the inner side of the adjacent side panels, forming a double-layer structure, which can improve the airtightness of the box body and make the trash can have better deodorization performance.

[0011] In the above-mentioned trash can, the curvature of the upper edges of the protruding plate body 1 and the protruding plate body 2 is consistent with the curvature of the top plate body. This structure ensures that the distance between the lower side of the top plate body and the upper edge of the protruding plate body will not change during the process of opening or closing the box cover, so that the box cover can be opened or closed smoothly without conflicting with the protruding plate body.

[0012] In the above-mentioned garbage bin, the outer side walls of the left and right plates are respectively fixedly connected with a lifting seat located on the upper side of the hinge seat, the lifting seat has a columnar lifting part, the swing arm gradually tilts backwards from the lower end to the upper end, and the upper half of the swing arm is located at the rear side of the lifting seat. After the large garbage bin is loaded with garbage, the weight is relatively heavy. At this time, by providing a lifting seat with a lifting part, it is convenient for the two forklift arms of the forklift to act on the lifting parts of the two lifting seats respectively, so that the garbage bin can be lifted by the forklift, making the process of carrying the garbage bin more convenient. The swing arm gradually tilts backwards from the lower end to the upper end, so that the upper half of the swing arm is located at the rear side of the lifting seat, thereby avoiding the lifting seat, which can facilitate the forklift arm of the forklift to extend to the lifting seat to lift the garbage bin.

[0013] In the above-mentioned trash bin, the upper end of the swing arm is plugged and fixed to the lower edge of the side plate on the same side. This structure can realize the connection between the swing arm and the bin cover without the aid of rivets, bolts and other connecting parts, so the connection is more convenient.

[0014] In the above-mentioned trash can, the top plate has a gripping opening near the front side thereof, and the operator can operate the box cover to open or close by inserting his hand into the gripping opening, which is more labor-saving and convenient.

[0015] In the above-mentioned rubbish bin, the bottom of the bin body is also provided with rollers, which can facilitate the movement of the rubbish bin and make the rubbish bin more convenient to use.

[0016] Compared with the prior art, this trash can has the following advantages:

[0017] 1. The trash can is also provided with a swing arm, the upper end of which is connected to the lid. Therefore, when the lid is opened, the weight of the lid is mainly supported by the swing arm, and the user only needs to apply force to drive the lid to rotate, so that the lid opening is more labor-saving and convenient. At the same time, when the lid only needs to be opened to a certain angle to throw away the garbage, the swing arm still supports the lid. At this time, the operator only needs to provide a force to keep the lid fixed with one hand, and throw the garbage into the box with the other hand, so it will also be more labor-saving.

[0018] 2. The box body is also provided with a torsion spring, which can make the swing arm have an upward swinging tendency after the swing arm swings backward. Therefore, the torsion spring can provide a force to assist the box cover to swing upward, making the process of closing the box cover less laborious. In addition, during the process of opening the box cover, the torsion spring can also play a buffering role, so that the box cover can be opened stably, avoiding the box cover from falling down instantly and colliding with the box body quickly, making the process of opening the box cover more convenient.
