Description

Technical Field

[0001] This utility model relates to the field of trash can technology, specifically to a trash can. Background Technology

[0002] Trash cans are used to hold household waste. Existing trash cans are typically manufactured in factories using molds, then assembled with lids, and finally packaged and shipped to users. However, larger trash cans require larger packaging boxes and occupy more transportation space, increasing transportation costs. Furthermore, because the interior of the trash can is hollow, it is easily deformed during transport, increasing the risk of customer complaints. To address this, existing technologies have proposed a modular trash can where each side is molded separately and then assembled. However, in existing modular trash cans, adjacent side panels are usually connected by other connectors, such as the connection between two side panels via support columns disclosed in Chinese patent CN217228837U. This modular method increases the number of parts in the trash can, requiring more molds and increasing production costs, while also making assembly more difficult for users. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] This utility model mainly addresses the shortcomings of the existing technology, specifically relating to a trash can that solves the problems of existing trash cans having many parts, increasing costs, and making assembly more complicated.

[0005] (II) Technical Solution

[0006] This utility model relates to a trash can, including several connecting plates and a base. The connecting plates are connected end to end by a splicing structure to form a cylindrical body. One end of the cylindrical body is connected to the base, and the other end forms a trash disposal opening. The splicing structure includes a first connecting part and a second connecting part disposed between two adjacent connecting plates. The first connecting part and the second connecting part are respectively provided on opposite sides of the connecting plates. The first connecting part of the connecting plate is connected to the second connecting part of the adjacent connecting plate, and the second connecting part of the connecting plate is connected to the first connecting part of another adjacent connecting plate. The first connecting part of the connecting plate is positioned to limit the adjacent connecting plate in a first direction, and the second connecting part of the connecting plate is positioned to limit the other adjacent connecting plate in a second direction. The first direction and the second direction are opposite in the axial direction of the cylindrical body.

[0007] The advantage is that by using the splicing structure between two adjacent connecting plates to fix the connecting plates, no other structure is needed for splicing between the connecting plates, reducing molds and production costs. Installation is as simple as aligning and snapping together the first and second connecting parts of two adjacent connecting plates. The first and second connecting parts on the same connecting plate have opposite limiting directions for their adjacent connecting plates. This means that when the second connecting plate is installed from top to bottom along the axial direction of the cylinder, based on the first connecting plate, the whole formed by the first and second connecting plates has a first connecting part and a second connecting part on each side. When installing the third connecting plate, it can also be installed from top to bottom along the axial direction of the cylinder onto the whole formed by the first and second connecting plates. And so on, each connecting plate can be installed from top to bottom along the axial direction of the cylinder onto the previous connecting plate, making installation more convenient and providing a better user experience.

[0008] In one optional embodiment, the first connecting part forms a first limiting groove with an opening facing a first direction on the connecting plate, and the second connecting part forms a second limiting groove with an opening facing a second direction on the connecting plate. When the first connecting part and the second connecting part between two adjacent connecting plates are installed, the first limiting groove and the second limiting groove are engaged in the axial direction of the cylinder.

[0009] The advantage is that by setting the first and second connecting parts on the same connecting plate as two limiting grooves with opposite openings, the first and second connecting parts of the two adjacent connecting plates can approach each other to complete the snap-fit ​​fixation when they are spliced ​​together.

[0010] In one optional embodiment, the first connecting portion includes a first body and a first limiting portion. One end of the first body is connected to the connecting plate, and the other end is connected to the first limiting portion, forming a first limiting groove between the first body and the first limiting portion. The second connecting portion includes a second body and a second limiting portion. One end of the second body is connected to the connecting plate, and the other end is connected to the second limiting portion, forming a second limiting groove between the second body and the second limiting portion. The first limiting portion and the second limiting portion extend in opposite directions in the axial direction of the cylinder. When two adjacent connecting plates are installed, the first limiting portion and the second limiting portion move closer to each other along the axial direction of the cylinder until the first body and the second limiting portion engage. When the second body engages with the first limiting portion, it restricts the two adjacent connecting plates from disengaging in a direction perpendicular to the axial direction of the cylinder.

[0011] The advantage is that by cooperating with the first main body and the second limiting part, and cooperating with the second main body and the first limiting part, the first connecting part and the second connecting part form a ring-shaped snap-fit, and the snap-fit ​​between the two is more secure and reliable.

[0012] In one optional embodiment, the included angle between the first body and the first limiting part is equal to the included angle between the second body and the second limiting part, both being right angles.

[0013] The advantage is that when the included angle between the main body and the limiting part is set to a right angle, it facilitates production and processing. On the other hand, the right angle can effectively reduce the situation where the first connecting part and the second connecting part separate due to sliding during the splicing of the side panels, making the splicing more solid and reliable.

[0014] In one optional embodiment, the first body has a reinforcing portion at one end away from the first limiting portion, and / or the second body has a reinforcing portion at one end away from the second limiting portion; the reinforcing portion extends to the side wall of the connecting plate.

[0015] The advantage is that the reinforcement section enhances the strength of the splicing structure and reduces damage to the splicing structure caused by violent assembly or collisions.

[0016] In one optional embodiment, at least the reinforcing portion of the first connecting portion and the second connecting portion are disposed on the inner sidewall of the connecting plate, so that when the first connecting portion and the second connecting portion are connected, the first connecting portion and the second connecting portion are located inside the cylinder.

[0017] The advantage is that the hidden splicing structure makes the outer surface of the trash can simple and beautiful, and also avoids damage to the splicing structure.

[0018] In one optional embodiment, the side wall of the connecting plate is provided with a snap-fit ​​portion, and the side wall of the adjacent connecting plate is provided with a snap-fit ​​engagement portion that cooperates with the snap-fit ​​portion. When the two connecting plates connected by the first connecting portion and the second connecting portion rotate relative to each other, the snap-fit ​​portion cooperates with the snap-fit ​​engagement portion to restrict the movement of the two connecting plates in the axial direction of the cylinder.

[0019] The advantage is that it fixes the adjacent side panels in both the horizontal and vertical directions, making the trash can body more stable and reliable.

[0020] In one optional embodiment, the snap-fit ​​portion is a snap-fit ​​groove; the snap-fit ​​groove is disposed adjacent to the first connecting portion, and the second connecting portion forms the snap-fit ​​mating portion; when the two connecting plates connected by the first connecting portion and the second connecting portion rotate relative to each other, the second connecting portion moves into the snap-fit ​​groove; and / or, the snap-fit ​​groove is disposed adjacent to the second connecting portion, and the first connecting portion forms the snap-fit ​​mating portion; when the two connecting plates connected by the first connecting portion and the second connecting portion rotate relative to each other, the first connecting portion moves into the snap-fit ​​groove.

[0021] In one optional embodiment, a top frame is also included, which is located at one end of the cylinder away from the base and is detachably connected to each of the connecting plates, and the middle of the top frame has an opening communicating with the waste disposal port.

[0022] The advantage is that the top frame is used to secure the top of the side panels and to hide the gap between adjacent side panels at the top, preventing dirt from entering the gap.

[0023] In one optional embodiment, the device further includes a cover seat and a flip cover. The cover seat is detachably disposed in the top frame and is engaged with the top frame by a snap-fit. The cover seat is rotatably connected to the flip cover. An elastic element is provided between the cover seat and the flip cover, which is adapted to open the flip cover under the force of the elastic element when the flip cover is driven. And / or, the device further includes a pressure ring for fixing the garbage bag, which is disposed in the top frame or the cylinder. When the garbage can includes a cover seat and a flip cover, the pressure ring is disposed in the cover seat.

[0024] The advantage is that the pressure ring can be used to secure the garbage bag and prevent it from slipping to the bottom of the bin. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] like Figure 1-5As shown, this utility model relates to a trash can, including a plurality of connecting plates 10 and a base 20. The plurality of connecting plates 10 are connected end to end by a splicing structure 11 to form a cylindrical body. One end of the cylindrical body is connected to the base 20, and the other end forms a trash can opening. The splicing structure 11 includes a first connecting part 12 and a second connecting part 13 disposed between two adjacent connecting plates 10. The first connecting part 12 and the second connecting part 13 are respectively provided on opposite sides of the connecting plates 10. The first connecting part 12 of the connecting plate 10 is connected to the second connecting part 13 of the adjacent connecting plate 10, and the second connecting part 13 of the connecting plate 10 is connected to the first connecting part 12 of another adjacent connecting plate 10. The first connecting part 12 of the connecting plate 10 is positioned above the adjacent connecting plate 10 in a first direction, and the second connecting part 13 of the connecting plate 10 is positioned above the other adjacent connecting plate 10 in a second direction. The first direction and the second direction are opposite in the axial direction of the cylindrical body.

[0039] When the splicing structure 11 between two adjacent connecting plates 10 is used to fix the connecting plates 10, no other structure is needed for the splicing between the connecting plates 10, reducing molds and production costs. Installation is simpler; the first connecting part 12 and the second connecting part 13 of the two adjacent connecting plates 10 are aligned and snapped together. Figure 5 As shown, the first connecting portion 12 and the second connecting portion 13 on the same connecting plate 10 have opposite limiting directions on their adjacent connecting plates 10. This allows the second connecting plate 10 to be installed from top to bottom along the axial direction of the cylinder, based on the first connecting plate 10. The integral formed by the first connecting plate 10 and the second connecting plate 10 has the first connecting portion 12 and the second connecting portion 13 on both sides. When the third connecting plate 10 is installed, it can also be installed from top to bottom along the axial direction of the cylinder on the integral formed by the first connecting plate 10 and the second connecting plate 10. And so on. Each connecting plate 10 can be installed from top to bottom along the axial direction of the cylinder on the previous connecting plate 10, making installation more convenient and providing a better user experience.

[0040] The connecting plate 10 is the side plate of the trash can. Several connecting plates 10 are connected end to end to form a hollow cylinder with openings at the top and bottom. This cylinder is the main body of the trash can. The base 20 is used to connect to the bottom of the cylinder so that the trash can has a shape with an opening at the top. This opening is the trash disposal port, allowing users to put trash into the trash can through the trash disposal port. The connection between the base 20 and the cylinder can be installed by snap-fit ​​connection and / or plug-in engagement. For example, the base 20 has a first mounting groove, and the bottom of the cylinder is plugged into the first mounting groove, so that the cylinder is fixedly installed on the base 20. For the reliability after installation, snap-fit ​​fasteners that can be interlocked can also be set on the first mounting groove and the bottom of the cylinder. The shape of the base 20 is not limited in this example. The base 20 only needs to be able to close the bottom of the cylinder.

[0041] The connecting plates 10 are connected end-to-end by a splicing structure 11, which includes a first connecting part 12 and a second connecting part 13. That is, the connecting plates 10 have a first connecting part 12 and a second connecting part 13 on opposite sides. The first connecting part 12 on one side of a connecting plate 10 and the second connecting part 13 on the side of an adjacent connecting plate 10 cooperate to fix two adjacent connecting plates 10. More specifically, when the cylinder is composed of four connecting plates 10, namely a first connecting plate 10, a second connecting plate 10, a third connecting plate 10, and a fourth connecting plate 10, then the first connecting part 12 of the first connecting plate 10... The first connecting part 12 of the second connecting plate 10 is connected to the second connecting part 13 of the third connecting plate 10, the first connecting part 12 of the third connecting plate 10 is connected to the second connecting part 13 of the fourth connecting plate 10, and the first connecting part 12 of the fourth connecting plate 10 is connected to the second connecting part 13 of the first connecting plate 10, so that the first connecting plate 10, the second connecting plate 10, the third connecting plate 10 and the fourth connecting plate 10 form a cylinder. When there are 3 or 5 or more connecting plates 10, the installation method is similar to the connection method of the above 4 connecting plates 10, and will not be described in detail.

[0042] To ensure the reliability of the connecting plate 10 after installation and to facilitate positioning, a matching stepped splicing surface can be provided on the opposite sides of two adjacent connecting plates 10, making the splicing between the connecting plates 10 more compact. The first connecting part 12 and the second connecting part 13 can be provided on the splicing surface, or on the side wall of the connecting plate 10, or on both the splicing surface and the side wall of the connecting plate 10.

[0043] The first connecting portion 12 of the connecting plate 10 limits the adjacent connecting plate 10 in a first direction. Specifically, the first connecting portion 12 limits the second connecting portion 13 of the adjacent connecting plate 10 in the first direction to limit the adjacent connecting plate 10. Preferably, the second connecting portion 13 presses against the first connecting portion 12, so the first connecting portion 12 restricts the movement of the second connecting portion 13 in the opposite direction to the first direction. That is, the first connecting portion 12 of the connecting plate 10 restricts the movement of the adjacent connecting plate 10 in the opposite direction to the first direction. The way in which the second connecting portion 13 of the connecting plate 10 limits the adjacent connecting plate 10 in the second direction is the same as described above, and will not be repeated.

[0044] The first direction and the second direction are opposite in the axial direction of the cylinder, so that the connecting plate 10 limits the adjacent connecting plate 10 on both sides in different directions. The connecting plate 10 installed first will restrict the connecting plate 10 installed later to move in the same direction, so that the connecting plate 10 installed later can be installed on the connecting plate 10 installed earlier in one direction. It should be noted that when the first connecting plate 10 is used as the base plate, the second connecting plate 10 is installed on the first connecting plate 10, and the third connecting plate 10 is installed on the second connecting plate 10, then the second connecting plate 10 is the connecting plate 10 installed first, and the third connecting plate 10 is the connecting plate 10 installed later. In this example, the preferred axial direction of the cylinder is the vertical direction. When the first direction is upward, the second direction is downward, or when the first direction is downward, the second direction is upward.

[0045] In one optional embodiment, the first connecting portion 12 forms a first limiting groove 121 with an opening facing a first direction on the connecting plate 10, and the second connecting portion 13 forms a second limiting groove 131 with an opening facing a second direction on the connecting plate 10. When the first connecting portion 12 and the second connecting portion 13 between two adjacent connecting plates 10 are installed, the first limiting groove 121 and the second limiting groove 131 are engaged in the axial direction of the cylinder. The first connecting portion 12 and the second connecting portion 13 on the same connecting plate 10 are set as two limiting grooves with opposite openings so that when two adjacent connecting plates 10 are spliced, the first connecting portion 12 and the second connecting portion 13 of the two adjacent connecting plates 10 can approach each other to complete the engagement and fixation. When the first limiting groove 121 and the second limiting groove 131 are engaged, preferably the opening of the first limiting groove 121 and the opening of the second limiting groove 131 approach each other and engage together. If the opening of the first connecting part 12 is preferably facing upward, then the opening of the second connecting part 13 is facing downward, so that the connecting plates 10 installed later can be installed from top to bottom on the connecting plates 10 installed earlier, making installation more convenient, and the connecting plates 10 installed earlier can prevent the mounting plates installed later from falling down and detaching from the mounting position.

[0046] like Figure 3 As shown, in an optional embodiment, the first connecting portion 12 includes a first body 122 and a first limiting portion 123. One end of the first body 122 is connected to the connecting plate 10, and the other end is connected to the first limiting portion 123, forming a first limiting groove 121 between the first body 122 and the first limiting portion 123. The second connecting portion 13 includes a second body 132 and a second limiting portion 133. One end of the second body 132 is connected to the connecting plate 10, and the other end is connected to the second limiting portion 133, forming a second limiting groove 131 between the second body 132 and the second limiting portion 133. The first limiting portion 123 and the second limiting portion 133 extend in the axial direction of the cylinder. The directions are opposite; when two adjacent connecting plates 10 are installed, the first limiting part 123 and the second limiting part 133 approach each other along the axial direction of the cylinder until the first main body 122 and the second limiting part 133 cooperate. When the second main body 132 cooperates with the first limiting part 123, it restricts the two adjacent connecting plates 10 from separating in a direction perpendicular to the axial direction of the cylinder. Through the cooperation of the first main body 122 and the second limiting part 133 and the cooperation of the second main body 132 and the first limiting part 123, the first connecting part 12 and the second connecting part 13 form a ring-shaped snap-fit, and the snap-fit ​​is more secure and reliable. Preferably, the first main body 122 and the connecting part are fixedly connected, such as integrally formed, and the first main body 122 is a transverse structure. The first limiting part 123 has a vertical structure, which makes the first connecting part 12 form a hook similar to the shape of "7". The second connecting part 13 has the same design, except that the first limiting part 123 and the second limiting part 133 are oriented in opposite directions, which makes the first connecting part 12 and the second connecting part 13 oriented in opposite directions. The first limiting groove 121 is formed by the connecting part, the first limiting part 123 and the first main body 122, and the first main body 122 is formed as the bottom of the first limiting groove 121. The second limiting groove 131 is also set in the same way, which will not be described in detail.

[0047] Understandably, the first limiting groove 121 can be directly formed on the first limiting part 123. For example, the first limiting groove 121 (not shown in the figure) is formed by recessing the end of the first limiting part 123 away from the first body 122 toward the end close to the first body 122. The second limiting groove 131 can be directly formed on the second limiting part 133. When the first connecting part 12 and the second connecting part 13 are engaged, the first limiting groove 121 and the second limiting groove 131 are engaged.

[0048] like Figure 3As shown, in an optional embodiment, the included angle between the first main body 122 and the first limiting part 123 is equal to the included angle between the second main body 132 and the second limiting part 133, both being right angles. When the included angle between the main body and the limiting part is set to a right angle, it facilitates production and processing. On the other hand, the right angle can effectively reduce the situation where the first connecting part 12 and the second connecting part 13 separate due to sliding during the splicing of the side panels, making the splicing more firm and reliable.

[0049] Understandably, the included angle can also be set to an acute angle or an obtuse angle (not shown in the figure), as long as the first limiting groove 121 and the second limiting groove 131 can be locked together. Correspondingly, in order to ensure the smooth installation of the first connecting part 12 and the second connecting part 13, the angle of the main body relative to the connecting plate 10 can be adjusted to adjust the opening of the first limiting groove 121 and the second limiting groove 131 so as to facilitate smoother assembly.

[0050] In one optional embodiment, a reinforcing portion 14 is provided at one end of the first main body 122 away from the first limiting portion 123, and / or a reinforcing portion 14 is provided at one end of the second main body 132 away from the second limiting portion 133; the reinforcing portion 14 extends to the side wall of the connecting plate 10; the reinforcing portion 14 is provided to enhance the strength of the splicing structure 11 and reduce damage to the splicing structure 11 caused by violent assembly or collision of the barrel body; preferably, the reinforcing portion 14 is an extension structure provided at the end of the first main body 122 and / or the second main body 132. Extending to the connecting plate 10 and connected to the side wall of the connecting plate 10, the reinforcing part 14 has a large connection area with the side wall of the connecting plate 10, which can effectively enhance the tensile strength of the splicing structure 11, and also enhance the strength of the splicing structure 11 when bent toward the inside or outside of the cylinder. In order to hide the splicing structure 11, the reinforcing part 14 is preferably provided on the inner side wall of the connecting plate 10. It can be understood that the reinforcing part 14 can also be provided on the outer side wall of the connecting plate 10, or even on the side wall between the two connecting plates 10, such as setting a groove on the side wall to specifically set the reinforcing part 14.

[0051] In this example, the reinforcing part 14 consists of three reinforcing ribs located on the side wall of the connecting part, with the three reinforcing ribs arranged side by side on the side wall. In this example, the reinforcing part 14 and the connecting plate 10 are preferably integrally formed. Of course, they can also be separately formed and then assembled. It is understood that the reinforcing part 14 can also be a flat plate structure, which is connected to the side wall of the connecting plate 10. It is understood that the reinforcing ribs can also be arranged in a way that expands outward from the direction away from the connecting plate 10.

[0052] In one optional embodiment, the first connecting portion 12 and the second connecting portion 13, at least the reinforcing portion 14, are disposed on the inner sidewall of the connecting plate 10, so that when the first connecting portion 12 and the second connecting portion 13 are connected, the first connecting portion 12 and the second connecting portion 13 are located inside the cylinder; the splicing structure 11 is hidden, making the outer surface of the trash can simple and beautiful, and also preventing damage to the splicing structure 11; in this example, the reinforcing portion 14 is preferably connected to the sidewall of the connecting plate 10, the first connecting portion 12 and the second connecting portion 13 are disposed on the side of the reinforcing portion 14 away from the connecting plate 10, and the first connecting portion 12 and the second connecting portion 13 have a tendency to bend towards the inside of the cylinder, so that when the two connecting plates 10 are connected, the first connecting portion 12 and the second connecting portion 13 are located inside the cylinder. To ensure the strength of the splicing structure 11, the first connecting portion 12 and the second connecting portion 13 can also extend out and be disposed on the opposite sides of the two adjacent connecting plates 10. This ensures that the first connecting part 12 and the second connecting part 13 are connected to both sides of the connecting plate 10, thereby enhancing the strength of the splicing structure 11.

[0053] In one optional embodiment, the side wall of the connecting plate 10 is provided with a snap-fit ​​portion 15, and the side wall of the adjacent connecting plate 10 is provided with a snap-fit ​​engagement portion 16 that cooperates with the snap-fit ​​portion 15. When the two connecting plates 10 connected by the first connecting portion 12 and the second connecting portion 13 rotate relative to each other, the snap-fit ​​portion 15 cooperates with the snap-fit ​​engagement portion 16 to restrict the movement of the two connecting plates 10 in the axial direction of the cylinder; so that the adjacent side plates are fixed in both the horizontal and vertical directions, making the garbage can body more stable and reliable.

[0054] In one optional embodiment, the snap-fit ​​portion 15 is a snap-fit ​​groove; the snap-fit ​​groove is disposed adjacent to the first connecting portion 12, and the second connecting portion 13 forms the snap-fit ​​mating portion 16. When the two connecting plates 10 connected by the first connecting portion 12 and the second connecting portion 13 rotate relative to each other, the second connecting portion 13 moves into the snap-fit ​​groove; and / or, the snap-fit ​​groove is disposed adjacent to the second connecting portion 13, and the first connecting portion 12 forms the snap-fit ​​mating portion 16. When the two connecting plates 10 connected by the first connecting portion 12 and the second connecting portion 13 rotate relative to each other, the first connecting portion 12 moves into the snap-fit ​​groove; in this example, the second body 132 of the second connecting portion 13 preferably forms the snap-fit ​​mating portion 16, so that the second body 132 snaps into the snap-fit ​​groove. It can be understood that a protrusion can be formed in the extension portion structure of the second body 132 to engage with the snap-fit ​​groove.

[0055] When multiple connecting plates 10 are installed, after the first connecting part 12 and the second connecting part 13 are positioned, the multiple connecting plates 10 are in a pre-locked state. The two adjacent connecting plates 10 can also rotate relative to each other, which makes it easy to adjust the installation position of the connecting plates 10 so that the multiple connecting plates 10 can be arranged into a circle to form a cylinder. By adjusting the relative rotation of the two adjacent connecting plates 10, the snap-fit ​​part 15 and the snap-fit ​​mating part 16 are engaged, so that the two adjacent connecting plates 10 are in a locked state, making the cylinder more stable and reliable.

[0056] Understandably, the snap-fit ​​part 15 can be a magnet, and the snap-fit ​​mating part 16 can be an iron sheet that magnetically engages with the magnet or a magnet with the opposite magnetic pole to the magnet in the snap-fit ​​part 15, as long as the magnetic engagement of the snap-fit ​​part 15 and the snap-fit ​​mating part 16 can restrict the movement of the two connecting plates 10 in the axial direction of the cylinder.

[0057] Understandably, the snap-fit ​​part 15 is an adhesive attachment, such as glue or Velcro, and the snap-fit ​​mating part 16 is the attachment to be glued. As long as the snap-fit ​​part 15 and the snap-fit ​​mating part 16 adhere and fit together, they can restrict the movement of the two connecting plates 10 in the axial direction of the cylinder.

[0058] like Figure 1 and 2 As shown, in an optional embodiment, a top frame 30 is also included. The top frame 30 is located at the end of the cylinder away from the base 20 and is detachably connected to several of the connecting plates 10. The top frame 30 has an opening in the middle that communicates with the garbage disposal port. The top frame 30 is provided to fix the top of the side plates and to hide the gap between adjacent side plates at the top, preventing dirt from entering the gap. Preferably, the top frame 30 is a hollow frame structure.
