Description

Technical Field

[0001] This application relates to the field of plastic buckets, and more particularly to a plastic bucket with a bottom-reinforced anti-tipping structure. Background Technology

[0002] Plastic buckets are buckets made of plastic, usually polyethylene or polypropylene, through blow molding or injection molding. They have a wide range of applications and are used as outer packaging for liquids and solids in industries such as chemicals, pesticides, pharmaceuticals, food, hardware, electronics, and electromechanical.

[0003] Ordinary plastic buckets, due to their lightweight material, do not have a very stable center of gravity. They are prone to tipping over in the event of accidents such as external impacts or collisions, making them unstable to use. Utility Model Content

[0004] In order to improve the problem of poor stability of plastic buckets, which are prone to tipping over when affected by the external environment, this application provides a plastic bucket with a bottom-reinforced anti-tipping structure.

[0005] The technical solution for a plastic bucket with a reinforced bottom anti-tipping structure provided in this application is as follows:

[0006] A plastic bucket with a bottom-reinforced anti-tipping structure includes a partition fixed to the bottom of the inner cavity of the plastic bucket body, which divides the inner cavity of the plastic bucket body into two parts: a receiving cavity and an empty cavity. A recessed groove is provided in the center of the bottom of the plastic bucket body. A connecting rod with its bottom end movably penetrating through the side wall of the plastic bucket body and fixed to a suction cup is movably installed in the center of the bottom of the empty cavity. A top plate is fixed to the top of the connecting rod. A cam assembly is provided in the empty cavity. The cam assembly includes a cam body movably installed in the empty cavity and corresponding to the top plate. The surface of the cam body abuts against the top of the top plate. When the cam body rotates clockwise, it drives the top plate to move downward. The downward movement of the top plate compresses the suction cup, expelling internal air and enhancing the adhesion between the suction cup and the contact surface.

[0007] By employing the above technical solution, when the cam body rotates clockwise, it drives the top plate to move downwards. Since the top plate is fixedly connected to the top of the connecting rod, the downward movement of the top plate causes the connecting rod and suction cup to move downwards together. During this process, the suction cup is compressed, thereby expelling internal air and allowing it to adhere more tightly to the contact surface. When the plastic bucket is placed on an unstable surface, the suction cup can enhance its adhesion to the surface by expelling internal air, thus preventing the plastic bucket from tipping over. Furthermore, because the partition divides the inner cavity into two parts, even if the liquid or items within the cavity exert significant lateral pressure on the plastic bucket, the structure within the cavity and the suction cup can provide sufficient support to maintain the stability of the plastic bucket.

[0008] Preferably, the surface of the connecting rod is fitted with a spring whose two ends are respectively fixed to the bottom of the top plate and the bottom of the cavity.

[0009] By employing the above technical solution, when the cam body rotates clockwise and pushes the top plate downward, spring one is compressed. This provides a buffering effect, making the downward movement of the top plate smoother and avoiding damage or instability caused by sudden force. When the cam body rotates counterclockwise or the external force disappears, the restoring force of spring one pushes the top plate upward, thereby causing the connecting rod and suction cup to rise together. In this way, the suction cup can easily separate from the contact surface, facilitating the movement or repositioning of the plastic bucket.

[0010] Preferably, the suction cup is located in the groove and its bottom is flush with the bottom of the plastic bucket body. The diameter of the suction cup is smaller than that of the groove, so that there is a gap between the groove and the suction cup.

[0011] By adopting the above technical solution, the gap between the groove and the suction cup provides the suction cup with additional elastic space and air circulation channel, thereby enhancing its ability to adapt to different contact surfaces and its adsorption effect.

[0012] Preferably, a rotating rod is fixedly connected to the cam body at both ends, which are respectively rotatably connected to the side wall of the plastic bucket body. A handle is fixedly connected to one end of the rotating rod. A limiting component is fixedly provided on the handle. The limiting component includes a limiting post fixed inside the handle. A rotating groove adapted to the shape of the limiting post is opened on the surface of the plastic bucket body. The limiting post is located in the rotating groove and can rotate 90 degrees clockwise.

[0013] By adopting the above technical solution, the limiting component includes a limiting post fixed inside the handle, which is adapted to the shape of a rotating groove opened on the surface of the plastic bucket body. When the handle is rotated clockwise, the limiting post will move in the rotating groove until it reaches a predetermined rotation angle (such as 90 degrees) and is blocked by the groove wall, thereby limiting further rotation of the handle.

[0014] Preferably, a rod is movably installed inside the limiting post, with one end movably penetrating the side wall of the handle and extending to the outside. The inner end of the rod is flush with the inner end of the limiting post. Two slots adapted to the shape of the rod are opened on the side of the inner cavity of the rotating groove, and the axes of the two slots intersect at a 90-degree angle.

[0015] By adopting the above technical solution, the inner end of the insert rod is flush with the inner end of the limiting post, ensuring that when the insert rod is fully retracted, it will not interfere with the normal movement of the limiting post within the rotating slot. The two slots correspond to two key positions of the cam body rotation (such as the initial position and the locked position). The combination design of the insert rod and slots ensures that the cam body can be stably locked in the required position after rotating to a predetermined angle, avoiding accidental rotation caused by external force interference.

[0016] The shape and size of the slot are designed to perfectly match the insert rod to ensure that the insert rod can be accurately inserted and secured in the slot.

[0017] Preferably, a locking block is movably mounted on the surface of the limiting post, and the locking block is engaged and fixed with the insertion rod.

[0018] By adopting the above technical solution, the locking and fixing method of the locking block and the insert rod ensures that the cam body can be stably locked in the required position after rotating to the predetermined angle, avoiding accidental rotation or dislodgement of the insert rod due to external interference.

[0019] Preferably, the surface of the insert rod is provided with a groove that matches the shape of the locking block. The locking block is located in the groove and slides longitudinally. The bottom of the locking block is fixedly connected to a spring, the other end of which is fixedly connected to the center of the bottom of the groove. The limiting post is provided with a through hole that matches the shape of the insert rod. The inner wall of the through hole is provided with a locking groove and a locking groove that match the shape of the locking block. The locking block is located in the locking groove or the locking groove.

[0020] By adopting the above technical solution, through the design of the sliding groove and the locking block, the insertion rod can move freely within the through hole of the limiting post and be locked when needed. This design makes the operation of the insertion rod more flexible and meets the usage needs of different scenarios. Under the action of the spring, the locking block can be firmly locked into the locking groove or the locking groove, ensuring the stability of the insertion rod in the locked state. Even under external force interference, the insertion rod is not easy to accidentally come out.

[0021] Preferably, the insertion rod is located in the through hole and can slide laterally. When the end of the insertion rod away from the handle is slidably inserted into the slot, the locking block slides from the second slot to the first slot.

[0022] By adopting the above technical solution, when the user needs to lock the insertion rod, they only need to push the insertion rod, causing it to slide along the through hole towards the slot. During the sliding process, the locking block will slide within the first slot as the insertion rod moves. When the insertion rod slides to the slot position, the locking block will be guided by the inner wall of the through hole and slide from the second slot to the first slot. At this time, the insertion rod is firmly locked in the desired position.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By incorporating a suction cup structure at the bottom of the plastic bucket and a cam assembly above the suction cup, the cam rotates clockwise, driving the top plate downwards. This forces the suction cup to expel internal air, enhancing the adhesion between the suction cup and the contact surface. This design effectively prevents the plastic bucket from tipping over on unstable surfaces, improving safety during use. Attached Figure Description

[0036] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0037] This application discloses a plastic bucket with a bottom-reinforced anti-tipping structure.

[0038] Reference Figure 1 , Figure 2A plastic bucket with a reinforced bottom anti-tipping structure includes a partition 2 fixed to the bottom of the inner cavity of the plastic bucket body 1. The surface of the partition 2 is fixed to the inner wall of the plastic bucket body 1. The interior of the plastic bucket body 1 is divided into upper and lower parts by the partition 2. The upper part is a receiving cavity 3, and the lower part is a hollow cavity 4. A groove 5 is formed in the center of the bottom of the plastic bucket body 1. The groove 5 is a recessed groove. The design of the groove 5 can increase the support area of ​​the bottom of the plastic bucket body 1. Although the bottom groove 5 makes the contact area between the bottom of the bucket and the ground seem to be reduced, in fact, this design makes the bottom of the bucket more stable when placed and less prone to tipping. The shape of the groove 5 can be set as arc or pentagonal concave, which can enhance the bending resistance of the bottom of the bucket, thereby improving the overall load-bearing capacity.

[0039] A connecting rod 7 is movably installed in the center of the bottom of the cavity 4. The top plate 8 is fixed to the top of the connecting rod 7. A spring 10 is sleeved on the surface of the connecting rod 7. The top and bottom of the spring 10 are respectively fixed to the bottom of the top plate 8 and the bottom of the inner cavity of the plastic bucket body 1. The bottom of the connecting rod 7 movably passes through the side wall of the plastic bucket body 1 and is fixed to a suction cup 6. The suction cup 6 is located in the groove 5. The bottom of the suction cup 6 is flush with the bottom of the plastic bucket body 1. The diameter of the suction cup 6 is smaller than the diameter of the groove 5.

[0040] A cam assembly 9 is provided inside the cavity 4. The cam assembly 9 includes a cam body 92 that is movably installed inside the cavity 4 and is corresponding to the top plate 8. A rotating rod 91 is located inside the cavity 4 and is horizontally arranged. Both ends of the rotating rod 91 are rotatably installed on the side wall of the plastic bucket body 1. The cam body 92 is fixedly sleeved on the surface of the rotating rod 91. The side of the top plate 8 near the cam body 92 abuts against the surface of the cam body 92.

[0041] The handle 93 is fixed to one end of the rotating rod 91. When the handle 93 is rotated 90 degrees clockwise, the cam body 92 is rotated 90 degrees clockwise. The cam body 92 will press the top plate 8. The top plate 8 will drive the connecting rod 7 fixed to it to move down and press the suction cup 6, so that the suction cup 6 is compressed and the internal air is discharged, thereby enhancing the adsorption force between the suction cup 6 and the contact surface.

[0042] In its initial state, the interior of the plastic bucket body 1 is divided into two parts by the partition 2: a receiving cavity 3 and an empty cavity 4. The suction cup 6 is located in the groove 5, flush with the bottom of the plastic bucket body 1, but with a slightly smaller diameter, leaving a gap to provide the suction cup 6 with additional elastic space and air circulation channels, thereby enhancing its ability to adapt to different contact surfaces and its adsorption effect. The spring 10 is in its natural state, and the connecting rod 7, the top plate 8, and the suction cup 6 are all in an uncompressed position. The cam body 92 maintains a certain gap with the top plate 8, without generating direct pressure.

[0043] When it is necessary to stably place the plastic bucket body 1 on a flat surface, the user can achieve this by turning the handle 93 clockwise. Turning the handle 93 90 degrees clockwise causes the rotating rod 91 and the cam body 92, which is fixedly sleeved on it, to rotate 90 degrees clockwise simultaneously. The convex surface of the cam body 92 gradually contacts and compresses the top plate 8. Due to the contour design of the cam body 92, the top plate 8 experiences a downward thrust. As the top plate 8 moves downward, it causes the connecting rod 7 to move downward as well, simultaneously compressing the spring 10. The downward movement of the connecting rod 7 causes the suction cup 6 to be compressed, expelling internal air and thus allowing the suction cup 6 to adhere more tightly to the contact surface, enhancing the suction force. When the cam body 92 rotates to its maximum position (i.e., after rotating 90 degrees clockwise), the top plate 8, connecting rod 7, and suction cup 6 are all in a stable, compressed state. At this time, the suction force between the suction cup 6 and the contact surface reaches its maximum, effectively preventing the plastic bucket from tipping over. Although the spring 10 is compressed, it is ready to provide a restoring force when needed.

[0044] When the plastic bucket needs to be moved or repositioned, the user can turn the handle 93 counterclockwise, causing the cam body 92 to rotate counterclockwise. The convex surface of the cam body 92 gradually moves away from the top plate 8, and the restoring force of the spring 10 begins to exert its effect, pushing the top plate 8 and connecting rod 7 upwards. The upward movement of the connecting rod 7 causes the internal pressure of the suction cup 6 to gradually recover, weakening the suction force between the suction cup 6 and the contact surface, facilitating the movement of the plastic bucket. When the cam body 92 has fully reset, the spring 10 also returns to its natural state, and the entire system is ready to enter the next operating cycle.

[0045] Reference Figure 3 , Figure 4 The limiting component 94 is provided on the handle 93. The limiting component 94 includes a limiting post 941 fixed inside the handle 93. A rotating groove 942 is provided on the surface of the plastic bucket body 1. One end of the limiting post 941 extends into the rotating groove 942, and the surface of the limiting post 941 abuts against the inner wall of the rotating groove 942. The limiting post 941 is constrained in the rotating groove 942, and its rotation range is limited to within 90 degrees.

[0046] In the initial state, one end of the limiting post 941 extends into the rotating groove 942, and the surface of the limiting post 941 is in close contact with the inner wall of the rotating groove 942. At this time, the handle 93 is in the initial position, and the limiting post 941 is also in the initial position of the rotating groove 942. When it is necessary to rotate the handle 93, the user will apply a torque to the handle 93, causing it to rotate around the rotating rod 91. Since the limiting post 941 is fixed inside the handle 93 and extends into the rotating groove 942, the rotation of the handle 93 will cause the limiting post 941 to rotate within the rotating groove 942.

[0047] During rotation, the surface of the limiting post 941 remains in close contact with the inner wall of the rotating groove 942, thus limiting the rotation range of the handle 93. Due to the shape and size design of the rotating groove 942, the rotation range of the limiting post 941 within it is limited to 90 degrees. When the handle 93 rotates to a certain extreme position, the limiting post 941 will hit one end wall of the rotating groove 942, thus preventing the handle 93 from rotating further. At this point, the user cannot apply a greater torque to make the handle 93 exceed this extreme position, thus achieving precise control over the rotation range of the handle 93. When it is necessary to return the handle 93 to its initial position, the user only needs to rotate the handle 93 in the opposite direction. During the reverse rotation, the limiting post 941 will gradually return to its initial position along the inner wall of the rotating groove 942. When the handle 93 has completely returned to its initial position, the limiting post 941 also returns to the initial position of the rotating groove 942 accordingly.

[0048] Reference Figures 4-7 The limiting post 941 has a through hole 944 at the center of one end. The insertion rod 943 is located in the through hole 944 and slides laterally. The surface of the insertion rod 943 abuts against the inner wall of the through hole 944. Two slots 945 that are adapted to the shape of the insertion rod 943 are respectively opened at both ends of the inner side of the rotating groove 942. The two slots 945 are arranged at right angles in space.

[0049] The surface of the insertion rod 943 is provided with a sliding groove 947. The locking block 946 is located in the sliding groove 947. The locking block 946 is a hemispherical locking block 946, and the surface of the locking block 946 abuts against the inner wall of the sliding groove 947. The height of the sliding groove 947 is greater than the diameter of the locking block 946, so that the locking block 946 can slide longitudinally in the sliding groove 947. A spring 948 is fixedly connected to the center of the bottom of the locking block 946. The bottom end of the spring 948 is fixedly connected to the center of the bottom of the inner cavity of the sliding groove 947. The locking groove 949 and the locking groove 9410, which are adapted to the shape of the locking block 946, are opened in the inner wall of the through hole 944. When the locking block 946 is engaged in the locking groove 949, the inner end of the insertion rod 943 is flush with the inner end of the limiting post 941. When the locking block 946 is engaged in the locking groove 9410, the insertion rod 943 is inserted into the slot 945.

[0050] When the locking block 946 is engaged in the slot 949, the inner end of the insert rod 943 is flush with the inner end of the limiting post 941. At this time, the insert rod 943 will not protrude from the through hole 944, nor will it interfere with the rotation of the limiting post 941 in the rotating groove 942. When it is necessary to fix the position of the limiting post 941 (and the connected handle 93), the user can push the insert rod 943 to pop the locking block 946 out of the slot 949 until the inner end of the insert rod 943 is aligned and inserted into the slot 945 in the rotating groove 942. During this process, the locking block 946 will automatically engage in the slot 9410 under the action of the spring 948, thereby fixing the position of the insert rod 943.

[0051] When it is necessary to unlock and retract the insertion rod 943, the user can pull the insertion rod 943 outward, causing the locking block 946 to pop out of the second locking slot 9410. The insertion rod 943 slides laterally until it is fully retracted into the through hole 944. At this time, the locking block 946 will automatically lock into the first locking slot 949 under the action of the second spring 948, returning to its initial state. The locking block 946 can be firmly locked into the first locking slot 949 or the second locking slot 9410 under the action of the second spring 948, ensuring the stability of the insertion rod 943 in the locked state. Even under external interference, the insertion rod 943 is not easy to accidentally dislodge.

[0052] The implementation principle of a plastic bucket with a bottom-reinforced anti-tipping structure in this application embodiment is as follows: The suction cup 6 located at the bottom of the plastic bucket body 1 is initially flush with the bottom of the bucket, and its diameter is slightly smaller than that of the groove 5, ensuring good adaptability and air circulation. When the handle 93 is rotated 90 degrees clockwise, the cam body 92 presses against the top plate 8, thereby pushing the connecting rod 7 and the suction cup 6 downward. During this process, the spring 10 is compressed, and the air inside the suction cup 6 is expelled, making it tightly adhere to the contact surface, enhancing the suction force, thereby effectively preventing the plastic bucket from tipping over. Furthermore, by setting the limiting component 94, it is ensured that the cam body 92 can be stably locked in the required position after rotating to the predetermined angle, avoiding accidental rotation or dislodgement of the insertion rod 943 due to external interference.

[0053] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
