Description

Technical Field

[0001] The utility model belongs to the field of trash cans, and in particular relates to a knob-type bucket cover assembly structure for stacked trash cans. Background Art

[0002] The lid of a flip-top trash can needs to be rotated and connected to the body of the trash can. However, it is basically impossible to transport trash can products in bulk as fully assembled finished products. The large transportation volume leads to high transportation costs. Most of them are transported in the form of "several bucket bodies stacked on top of each other, and several lids are placed together in the bucket body at the top". That is, the semi-finished trash can components need to be assembled again after being transported to the destination. Ultimately, whether it is assembled by the salesperson or by the user, due to the need for secondary assembly, the convenience and ease of assembly between the lid and the bucket body are particularly important for product design.

[0003] Existing flip-top trash cans that require assembly typically utilize cylindrical blocks and corresponding holes to create a rotating, snap-fit mechanism for convenient assembly. To ensure structural strength, some trash cans have these blocks and holes located in the inelastic areas of the head and body, respectively. This requires users to exert considerable force to press the blocks into the holes, resulting in a poor user experience. Furthermore, the production precision required for the block size is extremely high. If the block is too large, successful installation is impossible, while if it is too small, it can easily become loose and fall out.

[0004] In order to avoid the problem of excessive installation difficulty, another part of the trash can is equipped with a thinner, elastically deformable sheet structure or C-shaped buckle, and then a card block or card hole is set on the sheet structure, or the C-shaped buckle is used as a card fixing structure. When the user applies a little force during installation, the sheet structure or C-shaped buckle will undergo elastic deformation and smoothly form a rotational card. However, the card block and card hole are the main force-bearing structures during flipping, and the sheet structure or C-shaped buckle is obviously weaker in strength. Frequent flipping can easily cause it to deform or break, which in turn causes the lid to loosen and detach from the barrel body or fail to flip normally.

[0005] In summary, the inventor has designed a super-fast-joining rear-flip trash can, with a utility model patent application number of 202320718811X. It includes a large lid and a small locking lid, with matching elastic clips and a clamped portion between the two. The elastic clips are fastened to the clamped portion to completely lock the large lid and the small locking lid. However, the elastic clips and the clamped portion may not fit smoothly when fastened, and manual adjustment is required according to the matching structure of the two during manual operation, which is inconvenient and affects the user experience. Therefore, a simple structure and a direct and easy operation method are needed to separate and lock the lid and the locking lid. Summary of the Invention

[0006] In response to the problems in the related technology, the utility model proposes a knob-type bucket cover assembly structure for stacked trash cans, including a bucket cover and a locking cover. By rotating the limiting piece on the locking cover, it is snapped into the bucket cover limiting groove, thereby achieving the separation and fastening of the bucket cover and the locking cover.

[0007] The utility model is achieved in this way:

[0008] A knob-type lid assembly structure for stacking trash cans, comprising a trash can body with an opening at the upper end, the trash can body being wide at the top and narrow at the bottom, and multiple trash can bodies being stacked one on the other, the open end of the trash can body being provided with a trash can lid and a locking cover that can fit together, the locking cover being located on a side of the trash can lid close to the inside of the trash can body and being smaller than the trash can lid;

[0009] The barrel cover and the locking cover are coaxially arranged at the open end of the barrel body. A rotating member is provided in the locking cover. The rotating member is connected to a limiting member on the side close to the barrel cover. The limiting member includes a middle part and a locking part. The locking parts are symmetrically arranged on both sides of the middle part.

[0010] Two symmetrical limiting grooves are provided on one side of the barrel cover close to the locking cover, and the limiting grooves are provided with notches, and the notches of the two limiting grooves are opposite to each other; the locking portion is adapted to the limiting grooves; when the barrel cover and the locking cover are fitted together, the middle portion is located at a corresponding position between the two limiting grooves;

[0011] By rotating the rotating member, the locking portions at both ends of the limiting member rotate around the center of the middle portion and enter or move out of the limiting groove.

[0012] Preferably, the two limiting grooves are cooperatively connected to two sides of a circle formed by the rotation trajectory of the limiting member, and the limiting grooves can cover or partially cover the locking portion.

[0013] Specifically, the limiting groove does not cover the middle portion, that is, the limiting groove does not prevent the limiting member from performing circular rotation;

[0014] When the locking part rotates out of the limiting groove and moves between the two limiting grooves, the limiting groove cannot block the limiting piece, and the locking cover and the barrel cover can be separated from each other; when the locking cover and the barrel cover are fitted together and the locking part is rotated into the limiting groove and is covered or partially covered by the limiting groove, the limiting groove forms a blocking effect on the limiting piece, thereby realizing the mutual fitting and locking of the locking cover and the barrel cover.

[0015] Preferably, the shape of the locking portion is arc-shaped or polygonal.

[0016] Specifically, the locking portion is mainly used to lock into the limiting groove to achieve a limiting effect, and can be in the shape of an arc or a polygon such as a triangle or a quadrilateral.

[0017] Preferably, a connecting portion is provided on one side of the rotating member connected to the limiting member, and a connecting groove adapted to the connecting portion is provided on the limiting member; and the shape of the connecting portion is the same as that of the limiting member.

[0018] Specifically, the connecting portion and the connecting groove are connected to each other so that the rotating member can drive the limiting member to rotate synchronously.

[0019] Preferably, a recessed platform adapted to the size of the rotating member is provided on one side of the locking cover close to the inside of the barrel body, a connecting hole is provided in the middle of the recessed platform, and the connecting part passes through the connecting hole into the connecting groove and is connected to the limiting member.

[0020] Specifically, the rotating member is buckled in the concave platform to prevent it from sliding back and forth. A crossbar is also provided on one side of the rotating member close to the inside of the barrel, and the crossbar is for facilitating manual grasping and thus rotating the rotating member.

[0021] Preferably, a plurality of reinforcing ribs are provided on a side of the limiting groove away from the groove opening.

[0022] Specifically, the inclined structure of the reinforcing rib can ensure that the structure of the limiting groove is more secure and balanced.

[0023] A circular groove is provided between the notches of the two limiting grooves. The rotating member and the limiting member are connected to each other by screws. When the locking cover and the barrel cover are fitted together, the screws fall into the circular groove.

[0024] Preferably, a positioning block is provided in the barrel cover, and a positioning frame adapted to the positioning block is provided in the locking cover, and the positioning frame is arranged at a position of the locking cover close to the edge thereof.

[0025] Specifically, since the barrel cover is larger than the locking cover, the locking cover and the barrel cover need to have accurate corresponding positions. Different areas are set in the locking cover. Through the positioning frame and the positioning block, the barrel cover and the locking cover can be connected to avoid position deviation and prevent dislocation.

[0026] Preferably, a plurality of positioning grids are further provided in the locking cover, and the positioning grids are connected to the positioning frame.

[0027] Specifically, the provision of the positioning grid can enhance the stability and balance of the internal structure of the lock cover, achieve the effect of a type of reinforcement rib, and prevent the lock cover from being deformed due to excessive force when the lock cover is fastened to the barrel cover.

[0028] Preferably, the limiting member is integrally formed.

[0029] Specifically, the limiting member as a whole realizes the locking and opening between the lock cover and the barrel cover.

[0030] Preferably, a connecting rod portion is provided on the side of the locking cover close to the inside of the barrel body, a linkage rod is provided on the connecting rod portion, and a pedal is provided at the bottom of the barrel body. One end of the linkage rod is connected to the locking cover through the connecting rod portion, and the other end is connected to the pedal. The linkage rod is driven by the pedal to drive the locking cover to flip.

[0031] Specifically, the locking cover is driven by a connecting rod, which can limit the locking cover to rotate to a limited angle and will not rotate to the rear side of the barrel body. At the same time, it will not affect the rotation angle of the barrel cover, so that the barrel cover can be completely flipped back and hung on the rear side of the barrel body, with a gap between the barrel cover and the barrel body.

[0032] When the locking cover is connected to the barrel cover and locked, the opening and closing of the barrel cover and the locking cover can be controlled by the foot pedal; when the locking cover is separated from the barrel cover, the barrel cover is completely flipped back and hangs on the rear side of the barrel body, saving the overall occupied space.

[0033] Compared with the prior art, the present invention achieves the following beneficial effects:

[0034] The utility model provides a knob-type bucket cover assembly structure for stacked trash cans, including a bucket cover and a locking cover arranged coaxially, the bucket cover is symmetrically provided with limiting grooves, and the locking cover is provided with limiting members, which can be rotated to enter the limiting groove and engage with the limiting groove; or rotated out of the limiting groove to separate the two, thereby realizing the buckling or locking of the bucket cover and the locking cover; utilizing the knob-type structure of the rotating member, the bucket cover and the locking cover can be separated and locked by rotation, which avoids the problem of unsmooth engagement during the engagement process compared to the traditional manual engaging structure, and at the same time, the structural design of the knob is very simple, easy to replace and disassemble, and more convenient and comfortable for users to operate, which greatly improves the user experience.

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] Example

[0053] like Figures 1 to 10A knob-type lid assembly structure for stacking trash cans includes a body 101 with an opening at the top. The body 101 is wide at the top and narrow at the bottom. Multiple bodies 101 can be stacked together. The open end of the body 101 is provided with a lid 201 and a locking cover 301 that can fit together. The locking cover 301 is located on a side of the lid 201 close to the inside of the body 101 and is smaller than the lid 201.

[0054] The barrel cover 201 and the locking cover 301 are coaxially arranged at the open end of the barrel body 101. A rotating member 401 is provided in the locking cover 301. The rotating member 401 is connected to a limiting member 501 on the side close to the barrel cover 201. The limiting member 501 includes a middle portion 502 and a locking portion 503. The locking portions 503 are symmetrically arranged on both sides of the middle portion 502.

[0055] Two symmetrical limiting grooves 202 are provided on one side of the barrel cover 201 close to the locking cover 301. The limiting grooves 202 are provided with notches 203, and the notches 203 of the two limiting grooves 202 are opposite to each other; the locking portion 503 is adapted to the limiting grooves 202; when the barrel cover 201 and the locking cover 301 are attached to each other, the middle portion 502 is located at a corresponding position between the two limiting grooves 202;

[0056] By rotating the rotating member 401 , the locking portions 503 at both ends of the limiting member 501 rotate around the center of the middle portion 502 and enter or move out of the limiting groove 202 .

[0057] The limiting member 501 is integrally formed.

[0058] The limiting member 501 as a whole realizes the locking and opening between the locking cover 301 and the barrel cover 201.

[0059] The locking cover 301 is also provided with a connecting rod portion 302 on one side close to the inside of the barrel body 101, and a connecting rod 102 is provided on the connecting rod portion 302. A foot pedal 103 is also provided at the bottom of the barrel body 101. One end of the connecting rod 102 is connected to the locking cover 301 through the connecting rod portion 302, and the other end is connected to the foot pedal 103. The foot pedal 103 drives the connecting rod 102 to drive the locking cover 301 to flip.

[0060] By using the connecting rod 102 to drive the locking cover 301, the locking cover 301 can be limited to rotate at a limited angle and will not rotate to the rear side of the barrel body 101. At the same time, it will not affect the rotation angle of the barrel cover 201, so that the barrel cover 201 can be completely flipped back and hung on the rear side of the barrel body 101, and there is a gap between the barrel cover 201 and the barrel body 101.

[0061] When the locking cover 301 is connected to the barrel cover 201 and locked, the opening and closing of the barrel cover 201 and the locking cover 301 can be controlled by the pedal 103; when the locking cover 301 is separated from the barrel cover 201, the barrel cover 201 is completely flipped back and hangs on the rear side of the barrel body 101, saving the overall occupied space.

[0062] The two limiting grooves 202 are matched and connected to two sides of the circle formed by the rotation trajectory of the limiting member 501 , and the limiting grooves 202 can cover or partially cover the locking portion 503 .

[0063] The limiting groove 202 does not cover the middle portion 502, and the two ends of the limiting member 501 that are farthest apart are less than or equal to the maximum distance between the notches of the two opposing limiting grooves, and greater than the shortest distance between the notches of the two opposing limiting grooves. That is, the limiting groove 202 does not prevent the limiting member 501 from rotating in a circular motion.

[0064] When the locking portion 503 rotates out of the limiting groove 202 and moves between the two limiting grooves 202, the limiting groove 202 cannot block the limiting member 501, and the locking cover 301 and the barrel cover 201 can be separated from each other; when the locking cover 301 and the barrel cover 201 are fitted together, and the locking portion 503 is rotated into the limiting groove 202, and the locking portion 503 is covered or partially covered by the limiting groove 202, the limiting groove 202 forms a blocking effect on the limiting member 501, thereby realizing the mutual fitting and locking of the locking cover 301 and the barrel cover 201.

[0065] The shape of the locking portion 503 is arc or polygonal.

[0066] The locking portion 503 is mainly used to lock into the limiting groove 202 to achieve a limiting effect. It can be an arc or polygonal shape such as a triangle or a quadrilateral. The locking portion 503 in this embodiment is an arc structure.

[0067] A connecting portion 402 is provided on one side of the rotating member 401 that is connected to the limiting space, and a connecting groove 504 adapted to the connecting portion 402 is provided on the limiting member 501 ; the shape of the connecting portion 402 is the same as that of the limiting member 501 .

[0068] The connecting portion and the connecting groove have the same shape. The connecting portion 402 and the connecting groove 504 are connected with each other and are completely engaged. During the rotation process, the two remain in a relatively static state, and thereby the rotating member 401 can drive the limiting member 501 to rotate synchronously.

[0069] A recess 303 having a size adapted to that of the rotating member 401 is provided on one side of the locking cover 301 close to the interior of the barrel body 101 , and a connecting hole 304 is provided in the middle of the recess 303 . The connecting portion 402 passes through the connecting hole 304 into the connecting groove 504 and is connected to the limiting member 501 .

[0070] The rotating member 401 is buckled in the concave platform 303 to prevent it from sliding back and forth. A cross bar is also provided on one side of the rotating member 401 close to the inside of the barrel 101. The cross bar is for the convenience of manual grasping and then rotating the rotating member 401.

[0071] A plurality of reinforcing ribs 204 are provided on one side of the limiting groove 202 away from the groove opening 203 .

[0072] The inclined surface structure of the reinforcing rib 204 can ensure that the structure of the limiting groove 202 is more secure and balanced.

[0073] A circular groove 205 is provided between the notches 203 of the two limiting grooves 202 . The rotating member 401 and the limiting member 501 are connected to each other by screws. When the locking cover 301 and the barrel cover 201 are fitted together, the screws fall into the circular groove 205 .

[0074] A positioning block 206 is provided in the barrel cover 201 , and a positioning frame 305 adapted to the positioning block 206 is provided in the locking cover 301 . The positioning frame 305 is arranged at a position close to the edge of the locking cover 301 .

[0075] Since the barrel cover 201 is larger than the locking cover 301, the locking cover 301 and the locking structure of the barrel cover 201 need to correspond to each other accurately. Different areas are set in the locking cover 301. Through the positioning frame 305 and the positioning block 206, the barrel cover 201 and the locking cover 301 can avoid position deviation and prevent dislocation when they are connected.

[0076] A plurality of positioning grids 306 are further provided in the locking cover 301 , and the positioning grids 306 are connected to the positioning frame 305 .

[0077] The positioning grid 306 can enhance the stability and balance of the internal structure of the locking cover 301, and achieve the effect of a type of reinforcing rib, thereby preventing the locking cover 301 from being deformed due to excessive force when the locking cover 301 is fastened to the barrel cover 201.

[0078] The present invention provides a knob-type bucket cover 201 assembly structure for stacking trash cans, and its operating principle is as follows: when the locking cover 301 and the bucket cover 201 are separated from each other, the rotating part 401 is rotated so that the positions of the limiting part 501 and the limiting groove 202 do not overlap or cover each other, that is, the locking portion 503 of the limiting part 501 does not overlap with the limiting groove 202. After the locking cover 301 and the bucket cover 201 are completely fitted together, the rotating part 401 is rotated so that the locking portion 503 of the limiting part 501 enters the limiting groove 202, completing the buckling and locking of the locking cover 301 and the bucket cover 201; when the rotating part 401 is rotated so that the locking portion 503 of the limiting part 501 completely leaves the limiting groove 202, the locking effect of the two is released, and at this time the locking cover 301 and the bucket cover 201 can be separated from each other.

[0079] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience only and do not constitute any limitation to the present invention.
