Description

Technical Field

[0001] The utility model relates to the technical field of trash cans, and particularly relates to a trash can. Background Art

[0002] In the existing flip-top trash can, a lock catch and a lock tongue are usually arranged on the barrel body and the lid respectively. When the lock tongue cooperates with the lock catch, the lid is closed. When the lid is pressed, the lock tongue and the lock catch are unlocked, so that the lid can be popped open by the elastic force of the torsion spring. This kind of flip-top trash can has the advantage of convenient opening and closing of the lid and is favored by users.

[0003] However, the existing lock tongue generally protrudes from the top of the barrel body or the side of the lid facing the barrel body. For example, the Chinese utility model patent CN201121033Y discloses that a clamping column (equivalent to a clamping tongue) is arranged on the barrel body and protrudes from the top of the barrel body. When putting in relatively hard garbage, the lock tongue is easily knocked and broken, resulting in the failure of the lid of the trash can to close, which affects the user experience. Summary of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] The utility model mainly solves the deficiencies in the prior art, and particularly relates to a trash can, which solves the problem that the lock tongue of the trash can in the prior art is easily knocked and broken, resulting in the failure of the lid of the trash can to close.

[0006] (2) Technical Solutions

[0007] The utility model relates to a trash can, which includes a main body and a lid. An opening is provided in the middle of the main body. The lid is rotatably connected to the main body and can rotate relative to the main body to open or close the opening. An installation part is provided in the main body, and a first locking part is provided on the installation part. The top of the first locking part is lower than the top of the side wall of the main body close to the first locking part. A second locking part is provided on the lid; or an installation part is provided in the lid, and a first locking part is provided on the installation part. A shielding part for shielding the first locking part is provided on the side of the lid away from its rotation position with the main body. The height of the shielding part is not less than the height of the first locking part in the direction extending in the same direction as the shielding part. A second locking part is provided on the main body; when the first locking part and the second locking part cooperate and lock, the lid and the main body are kept in a state of closing the opening.

[0008] The advantage is that when the user disposes of garbage, the garbage will naturally be lifted to the area between the main body and the opened cover for disposal. And to ensure the smooth disposal of garbage and avoid soiling the trash can, the garbage will be lifted to the area between above the top of the main body and the inner side surface of the cover facing the main body for disposal. When the first locking part is installed on the main body and the top of the first locking part is lower than the top of the side wall of the main body near the first locking part, or when the first locking part is installed on the cover and a shielding part for shielding the first locking part is provided on the cover and the height of the shielding part is not less than the height of the first locking part in the direction same as the extending direction of the shielding part, the shielding part of the main body or the cover will form a certain protection for the first locking part. When disposing of garbage, even if the garbage touches the top end of the side wall of the main body or the shielding part, it can avoid the contact between the garbage and the first locking part, thereby preventing the first locking part from being knocked by the garbage during disposal and causing the first locking part to break, and further avoiding the problem of the failure of the bucket cover to close.

[0009] In an optional embodiment, the first locking part is a locking tongue and the second locking part is a locking buckle. When the locking tongue is inserted into the locking buckle, the first locking part and the second locking part are locked and cooperated.

[0010] The advantage is that the locking and cooperating manner of the locking tongue and the locking buckle is simple and efficient in operation, and generally they are common parts, which is convenient for replacement and installation.

[0011] In an optional embodiment, the installation part forms a depression at least at the first locking part in a direction away from the second locking part.

[0012] The advantage is that the installation part is recessed at the first locking part, which is convenient for arranging the first locking part in the depression. The top of the depression can support the garbage and avoid the contact between the garbage and the first locking part.

[0013] In an optional embodiment, the height by which the first locking part protrudes from the installation part is less than the depth of the depression.

[0014] The advantage is that the top end of the first locking part will not protrude out of the depression. When the garbage is being disposed of, the garbage will at most touch the top of the depression and generally will not touch the first locking part, reducing the probability of the first locking part being touched and damaged.

[0015] In an optional embodiment, a first jack is provided on the installation part, and the first locking part is detachably installed in the first jack.

[0016] The advantage is that detachably installing the first locking part in the first jack is convenient for replacement and simple in assembly.

[0019] In an alternative embodiment, after the first locking portion is inserted into the first jack in the first direction, when the first locking portion is driven in a direction opposite to the first direction, the first locking portion is detached from the first jack.

[0020] The advantage is that the directions of assembly and disassembly are opposite, which is more in line with the user's operating habits. When the directions of the two operations are the same, after the first locking portion is installed in place and pressure is continuously applied along the first direction, the first locking portion will disengage from the first jack. Generally, when the second locking portion cooperates with the first locking portion, a certain pressure will be applied to the first locking portion along the first direction, that is, the first locking portion is likely to fall off during the normal operation of closing the lid of the trash can, thus affecting the user experience.

[0021] In an alternative embodiment, the first jack penetrates the mounting portion, the first locking portion is inserted into the first jack and partially protrudes from the first jack in a direction away from the second locking portion, and the protruding portion of the first locking portion is driven to detach the first locking portion from the first jack.

[0022] The advantage is that the first locking portion is designed to protrude from the first jack by a part, which is convenient for the user to press this part to drive the disassembly of the first locking portion, and the disassembly method is simple.

[0023] In an alternative embodiment, the main body includes a barrel body and a pressing ring, the pressing ring is movably connected to the barrel body, and the mounting portion is provided in the pressing ring.

[0024] The advantage is that the pressing ring generally cooperates with the barrel body to fix the garbage bag. When the cover body cooperates with the pressing ring and the mounting portion is arranged on the pressing ring, it is convenient for the cover body to cooperate with the first locking portion on the mounting portion for fixing.

[0025] In an alternative embodiment, when the first locking portion is provided on the main body, a second jack is provided on the cover body, and the second locking portion is detachably connected to the second jack; or when the first locking portion is provided on the cover body, a second jack is provided on the main body, and the second locking portion is detachably connected to the second jack.

[0026] The advantage is that when the second locking portion is detachably connected to the second jack, it is convenient to replace the second locking portion. Description of the Drawings

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0038] Embodiment 1:

[0039] The utility model relates to a trash can, which comprises a main body 10 and a cover body 20. An opening 15 is formed in the middle of the main body 10. The cover body 20 is rotatably connected to the main body 10 and can rotate relative to the main body 10 to open or close the opening 15. An installation part 11 is arranged in the main body 10, and a first locking part 12 is arranged on the installation part 11. The top of the first locking part 12 is lower than the top of the side wall of the main body 10 close to the first locking part 12. A second locking part 21 is arranged on the cover body 20. When the first locking part 12 cooperates with the second locking part 21 to lock, the cover body 20 and the main body 10 are kept in a state of closing the opening 15.

[0040] When a user throws garbage, the user will naturally lift the garbage between the main body 10 and the opened cover body 20 for throwing. And in order to ensure the smooth throwing of the garbage and avoid soiling the trash can, the user will lift the garbage to the area between above the top of the main body 10 and below the inner side surface of the cover body 20 facing the main body 10 for throwing. When the first locking part 12 is installed on the main body 10 and the top of the first locking part 12 is lower than the top of the side wall of the main body 10 close to the first locking part, the main body 10 will form a certain protection for the first locking part 12, which can prevent the first locking part 12 from being knocked when throwing garbage and causing the first locking part 12 to break, thereby avoiding the problem of the failure of the bucket cover to close.

[0041] Among them, the main body 10 is used to form a garbage storage area. An opening 15 is formed in the middle of the top of the main body 10. The opening 15 is used as a channel for the user to throw garbage or for the garbage to enter the interior of the main body 10 from the outside. The main body 10 is at least the barrel of the trash can. The trash can further comprises a cover body 20. The cover body 20 is movably connected to the barrel. In this example, preferably, the cover body 20 is connected to the barrel through a rotating shaft structure, so that the cover body 20 can rotate relative to the barrel around the rotating shaft to open or close the opening 15.

[0042] It can be understood that the main body 10 may further comprise a barrel body and a retaining ring 14. The retaining ring 14 is movably connected to the barrel body. The retaining ring 14 can be inserted into the barrel body or hinged to the barrel body through a rotating shaft. Generally, the retaining ring 14 cooperates with the barrel body to fix the garbage bag. The cover body 20 is rotatably connected to the retaining ring 14.

[0043] In this example, an installation part 11 is provided in the main body 10, and a first locking part 12 is provided on the installation part 11. The installation part 11 is used to carry the first locking part 12. Preferably, the installation part 11 in this example is provided inside the main body 10, that is, inside the opening 15. On the one hand, it prevents the first locking part 12 from being broken off outside the main body 10. On the other hand, there are no structural parts on the main body 10, making the overall appearance of the trash can more beautiful. Preferably, the installation part 11 is a plate-like structure extending from the inner side wall of the main body 10 towards the opening 15. The installation part 11 can be integrally formed with the main body 10 or can be formed separately from the main body 10 and then fixed by assembly. Among them, the installation part 11 can be an annular edge surrounding the main body 10 for one week, or can be a partial edge on the side wall of the main body 10.

[0044] A first locking part 12 is provided on the installation part 11. To ensure that the top of the first locking part 12 is lower than the top of the main body 10, the installation part 11 is provided on the side wall of the main body 10 and has a certain distance from the top of the main body 10. The height of this distance is at least higher than the height of the first locking part 12 protruding from the installation part 11, so that the top of the first locking part 12 will not be higher than the plane where the top of the main body 10 is located. Even when garbage is thrown into the opening 15 along the side wall of the top of the main body 10, it will not contact the first locking part 12, avoiding collisions of some hard garbage, such as glass fragments, blades, batteries, etc. with the first locking part 12 and causing the first locking part 12 to break.

[0045] A second locking part 21 is provided on the cover body 20. When the cover body 20 rotates to the opening 15, the second locking part 21 is locked and cooperated with the first locking part 12, so that the cover body 20 and the main body 10 maintain the state of closing the opening 15.

[0046] In an alternative embodiment, the first locking part 12 is a locking tongue, and the second locking part 21 is a locking buckle. When the locking tongue is inserted into the locking buckle, the first locking part 12 and the second locking part 21 are locked and cooperated. The locking tongue and the locking buckle are commercially available parts on the market. Usually, the locking tongue has a raised block, and the locking buckle has a locking cavity for the raised block to insert. There are limiting claws inside or outside the locking cavity. When the raised block of the locking tongue is inserted into the locking cavity, it will drive the claw to clamp the raised block, thereby realizing the fixation of the locking tongue and the locking buckle. The locking and cooperation method of the locking tongue - locking buckle is simple and efficient in operation, and is generally a general part, which is convenient for replacement and installation.

[0047] In an alternative embodiment, the mounting portion 11 forms a recess 111 at least at the first locking portion 12 in a direction away from the second locking portion 21. Specifically, the mounting portion 11 is formed in a "U" shape, and the first locking portion 12 is mounted at the bottommost part of the "U"-shaped mounting portion 11. The recess 111 is provided at the first locking portion 12 of the mounting portion 11, facilitating the setting of the first locking portion 12 within the recess 111. When throwing garbage, the top of the recess 111 can support the garbage. Generally, even if the garbage touches the mounting portion 11, it will only touch the top of the mounting portion 11 and will not touch the first locking portion 12 at the recess 111, effectively avoiding damage to the first locking member by the garbage.

[0048] In an alternative embodiment, the height by which the first locking portion 12 protrudes from the mounting portion 11 is less than the depth of the recess 111. Specifically, the top end of the first locking portion 12 does not extend out of the recess 111. When the garbage is being thrown, the garbage will at most touch the top of the recess 111 and generally will not touch the first locking portion 12, reducing the probability of damage to the first locking portion 12 due to being touched.

[0049] In an alternative embodiment, a first insertion hole 13 is provided on the mounting portion 11, and the first locking portion 12 is detachably mounted in the first insertion hole 13. Specifically, in this example, the first insertion hole 13 preferably adapts to the shape of the first locking portion 12, and the first locking portion 12 and the first insertion hole 13 are detachably connected and fixed by means such as snap fit, interference fit, screws or bolts. This is convenient for replacement and has simple assembly. In this example, the first locking portion 12 and the first insertion hole 13 are preferably in snap fit or interference fit, with a simple fixing method, facilitating production and assembly. It only needs to be simply inserted along one direction, and no additional structural members are required to fix the first locking portion 12.

[0050] When the first locking portion 12 and the first insertion hole 13 are in snap fit, a limiting hole is provided on the hole side wall of the first insertion hole 13, and a limiting protrusion cooperating with the limiting hole is provided on the side wall of the first locking portion 12. When the first locking portion 12 and the first insertion hole 13 are in plug-in fit, the limiting protrusion and the limiting hole are in snap fit, thereby restricting the first locking portion 12 from coming out of the first insertion hole 13. Of course, the positions of the limiting protrusion and the limiting hole can be swapped to also achieve the limiting function.

[0051] In an alternative embodiment, after the first locking portion 12 is inserted into the first jack 13 in the first direction, when the first locking portion 12 is driven in a direction opposite to the first direction, the first locking portion 12 is detached from the first jack 13. Specifically, in this example, the preferred first direction is along the direction of the main body 10 towards the bottom of the main body 10. The assembly and disassembly directions are opposite, which is more in line with the user's operating habits. When the directions of the two operations are the same, after the first locking portion 12 is installed in place and pressure is continuously applied along the first direction, the first locking portion 12 will disengage from the first jack 13. Generally, when the second locking portion 21 cooperates with the first locking portion 12, the second locking portion 21 will apply a certain pressure to the first locking portion 12 along the first direction, that is, when the trash can is normally closed, it is easy for the first locking portion 12 to fall off, thus affecting the user experience.

[0052] In an alternative embodiment, the first jack 13 penetrates through the mounting portion 11. The first locking portion 12 is inserted into the first jack 13 and protrudes partially out of the first jack 13 in a direction away from the second locking portion 21. The protruding portion of the first locking portion 12 is driven to detach the first locking portion 12 from the first jack 13. Specifically, the thickness of the portion of the mounting portion 11 where the first locking portion 12 cooperates with the mounting portion 11 is greater than the thickness of the mounting portion 11, so that after the first locking portion 12 is installed with the first jack 13, a part of the first locking portion 12 can still protrude. When disassembling, the user only needs to reach into the main body 10, touch the protruding portion of the first locking portion 12, and press slightly upward (in the direction opposite to the first direction) to detach the first locking portion 12 from the first jack 13. The disassembly method is simple. Designing the first locking portion 12 to protrude partially out of the first jack 13 facilitates the user to press this portion to drive the disassembly of the first locking portion 12, and the disassembly method is simple.

[0053] In an alternative embodiment, the main body 10 includes a barrel body and a retaining ring 14. The retaining ring 14 is movably connected to the barrel body, and the mounting portion 11 is provided in the retaining ring 14. Specifically, when the mounting portion 11 is provided on the retaining ring 14, it is convenient for the cover body 20 to cooperate and be fixed with the first locking portion 12 on the mounting portion 11. In this example, preferably, the mounting portion 11 is provided on the side of the retaining ring 14 away from the barrel body. The shape of the retaining ring 14 in this example is not limited as long as it can cooperate with the barrel body and the cover body 20 and can fix the garbage bag.

[0054] In an alternative embodiment, a second jack 22 is provided on the cover body 20, and the second locking portion 21 is detachably connected to the second jack 22. Specifically, when the second locking portion 21 is detachably connected to the second jack 22, it is convenient to replace the second locking portion 21. In this example, preferably, the second locking portion 21 and the second jack 22 are connected by a snap fit or an interference fit. The specific cooperation method is relatively common in the prior art and will not be elaborated here again.

[0055] Embodiment 2 (not shown in the figure in this example):

[0056] The present utility model relates to a trash can, which includes a main body 10 and a cover body 20. An opening 15 is provided in the middle of the main body 10. The cover body 20 is rotatably connected to the main body 10 and can rotate relative to the main body 10 to open or close the opening 15. An installation portion 11 is provided in the cover body 20, and a first locking portion 12 is provided on the installation portion 11. A shielding portion (not shown in the figure) for shielding the first locking portion 12 is provided on one side of the cover body 20 away from its rotation position with the main body 10. The height of the shielding portion is not less than the height of the first locking portion 12 in the direction along the same direction as the extension direction of the shielding portion. A second locking portion 21 is provided on the main body 10; when the first locking portion 12 and the second locking portion 21 are cooperatively locked, the cover body 20 and the main body 10 are kept in a state of closing the opening 15.

[0057] In this example, an installation portion 11 is provided in the cover body 20, and a first locking portion 12 is provided on the installation portion 11. The installation portion 11 is used to carry the first locking portion 12. For example, a groove-shaped installation portion 11 is provided on the cover body 20, and the first locking portion 12 is arranged in the groove. When the garbage is put in, it can at most closely adhere to the inner side wall of the cover body 20 facing the barrel body. Generally, it is very difficult to touch the first locking portion 12 in the groove. Therefore, the first locking portion 12 can be effectively prevented from being broken off. Preferably, the installation portion 11 is a groove structure extending from the inner side wall of the cover body 20 facing the barrel body in a direction away from the second locking portion 21. The installation portion 11 can be integrally formed with the cover body 20 or can be formed separately from the cover body 20 and then fixed by assembly.

[0058] A first locking part 12 is provided on the installation part 11. To prevent the first locking part from breaking when contacting garbage during garbage disposal, in this example, a shielding part is preferably provided on the side of the cover body 20 away from its rotation position with the main body 10, that is, a shielding part is provided on the side of the cover body 20 facing the user. The shielding part is used to shield the first locking part 12 to prevent the first locking part 12 from contacting the garbage. It can be understood that the first locking part 12 is arranged at a position between the shielding part and the rotating shaft of the cover body 20 and the main body 10. To ensure a better shielding effect of the first locking part 12, in this example, the first locking part 12 is preferably arranged close to the shielding part. The shape of the shielding part is not limited in this example. In this example, the shielding part is preferably the side wall of the groove body of the groove-shaped installation part 11.

[0059] To better shield the first locking part 12, in this example, the height of the shielding part is preferably not less than the height of the first locking part 12 in the same direction as the extension direction of the shielding part. So that no matter how the shape or installation position of the first locking part 12 is set, as long as the first locking part 12 is smaller than the height of the shielding part in the same direction as the extension direction of the shielding part, the first locking part 12 can be hidden on the side of the shielding part facing the rotating shaft of the cover body 20 and the main body 10, and the first locking part 12 will not protrude from the end of the shielding part away from the cover body 20. Even if the garbage enters the barrel tangentially with the end of the shielding part away from the cover body 20, it will not touch the first locking part 12, making the anti-collision and breakage prevention effect of the first locking part 12 better.

[0060] It can be understood that when one end of the first locking part 12 away from the installation part 11 is misaligned with the installation part 11, that is, when the first locking part 12 is inclined in the closed state of the cover body 20, the perpendicular length of the extension line of the installation part 11 from the end of the first locking part 12 away from the installation part 11 is the height of the first locking part 12.

[0061] It can be understood that one end of the first locking part 12 away from the installation part 11 is higher than the side surface of the cover body 20 facing the main body 10. Therefore, the height of the first locking part 12 installed on the installation part 11 protruding from the surface of the installation part 11 should be less than the depth of the groove, so that the first locking part 12 can be completely hidden in the groove. Even when the garbage is put into the opening 15 along the inner side wall of the cover body 20, it will not contact the first locking part 12, avoiding the collision of some hard garbage, such as glass fragments, blades, batteries, etc. with the first locking part 12 and causing the first locking part 12 to break.

[0062] A second locking part 21 is provided on the main body 10. When the cover body 20 rotates to the opening 15, the second locking part 21 is locked and cooperated with the first locking part 12, so that the cover body 20 and the main body 10 maintain the state of closing the opening 15.

[0063] Wherein, a second jack 22 is provided on the main body 10, and the second locking portion 21 is detachably connected to the second jack 22. Specifically, when the second locking portion 21 is detachably connected to the second jack 22, it is convenient to replace the second locking portion 21. In this example, preferably, the second locking portion 21 and the second jack 22 are connected by a snap or interference fit. The specific cooperation method is relatively common in the prior art and will not be elaborated here again.

[0064] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations fall within the scope defined by the appended claims.
