[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0020] Please see Figures 1 to 3 The present invention provides a plastic bucket bottom reinforcement structure, which includes a reinforcement base 1, a plastic bucket bottom placed on the top of the reinforcement base 1, an auxiliary fixing plate 2 disposed around the top of the reinforcement base 1 and abutting and fixing the side wall of the bottom of the plastic bucket, and a reinforcement buffer plate 3 disposed on the top of the reinforcement base 1 and abutting the bottom of the plastic bucket.
[0021] In the embodiments of this utility model, please refer to Figure 2 The reinforced base 1 has a buffer groove 4 inside. The bottom end of the reinforced buffer plate 3 is fixedly installed with a connecting column 5 that slides in the buffer groove 4. The bottom end of the connecting column 5 is inserted with a rod 6, and the surface of the rod 6 is fitted with a buffer spring 7.
[0022] It should be noted that when liquid is poured into the plastic bucket, the liquid impacts the bottom of the bucket, creating pressure. This causes the reinforcing buffer plate 3 to be squeezed. Subsequently, the reinforcing buffer plate 3, through the connecting column 5, drives the insertion rod 6 to slide relative to each other, simultaneously squeezing the buffer spring 7. Under the restoring force of the buffer spring 7, the reinforcing buffer plate 3 is subjected to a buffering force, thereby buffering the bottom of the plastic bucket and reducing the pressure. This effectively reduces the pressure on the bottom of the plastic bucket, ensuring the reinforcement effect on the bottom of the plastic bucket, achieving the reinforcement treatment of the bottom of the plastic bucket, ensuring the stability of the bottom of the plastic bucket, and improving the practical effect of the device.
[0023] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 A fixed guide rod 8 is fixedly installed at the bottom of the auxiliary fixing plate 2. A connecting rod 9 inserted into the reinforcing base 1 is fixedly installed at the end of the fixed guide rod 8 away from the auxiliary fixing plate 2. A slider 10 is fixedly installed at the end of the connecting rod 9 away from the fixed guide rod 8. An adjusting spring 11 is sleeved on the surface of the connecting rod 9. The top of the inside of the auxiliary fixing plate 2 is set as an inclined surface.
[0024] It should be noted that when the plastic bucket is placed on the reinforced base 1, the bottom of the plastic bucket will come into contact with the auxiliary fixing plate 2. Since the top surface of the auxiliary fixing plate 2 is set as an inclined surface, the auxiliary fixing plate 2 is pushed, and then the auxiliary fixing plate 2 drives the connecting rod 9 to slide through the fixed guide rod 8. The connecting rod 9 drives the slider 10 to slide relative to each other in the reinforced base 1, while squeezing the adjusting spring 11. This makes the sliding of the auxiliary fixing plate 2 more stable. When the bottom of the plastic bucket slides into the inside of the auxiliary fixing plate 2, the adjusting spring 11 will make the auxiliary fixing plate 2 stably contact the side wall of the plastic bucket under the reset force, effectively ensuring the fixed installation of the plastic bucket and strengthening the bottom side wall to provide a buffer force to the inside, ensuring the fixation of the plastic bucket while reducing the internal pressure on the plastic bucket.
[0025] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 The side wall of the reinforced base 1 is provided with a groove that matches the connecting rod 9. The size of the groove is smaller than the diameter of the fixed guide rod 8 and the slider 10. The side wall of the reinforced base 1 is provided with an arc-shaped groove.
[0026] It should be noted that the opening of the slot ensures that the connecting rod 9 slides stably without causing the slider 10 to slide out of the reinforcing base 1 or the fixed guide rod 8 to slide into the interior of the reinforcing base 1, thus ensuring the stable operation of the device. At the same time, the opening of the arc-shaped slot allows the fixed guide rod 8 to slide stably within the slot, making the sliding of the auxiliary fixing plate 2 more stable and convenient.
[0027] In the embodiments of this utility model, please refer to Figures 1 to 3 The inner top of the reinforced buffer plate 3 is set to be arc-shaped.
[0028] It should be noted that when the plastic bucket is placed on the surface of the reinforced buffer plate 3, most plastic buckets are designed with a central arc shape in order to reduce pressure. The arc shape of the reinforced buffer plate 3 ensures a better fit to the bottom of the plastic bucket while providing stable cushioning.
[0029] The working principle of the plastic bucket bottom reinforcement structure provided by this utility model is as follows:
[0030] After placing the device in a suitable position, the plastic bucket is then taken and placed on top of the reinforced base 1, so that the bottom of the plastic bucket abuts against the auxiliary fixing plate 2. Since the top of the auxiliary fixing plate 2 is set with an incline, the auxiliary fixing plate 2 will slowly slide outward. Then, the fixing guide rod 8 drives the connecting rod 9 and the slider 10 to slide while squeezing the adjusting spring 11. When the plastic bucket slowly slides to the bottom of the auxiliary fixing plate 2, the adjusting spring 11 will return to its original position, causing the auxiliary fixing plate 2 to stably abut against the bottom side wall of the plastic bucket. This achieves stable installation of the device at the bottom of the plastic bucket, ensuring that the bottom of the plastic bucket is reinforced while making the device applicable to plastic buckets of different sizes. This makes the installation process more convenient and stable, and improves the applicability of the device. At the same time, the bottom of the plastic bucket will abut against the reinforced buffer plate 3. The arc-shaped setting of the top of the reinforced buffer plate 3 can effectively abut against the bottom of the plastic bucket, improving the fixing effect.
[0031] When liquid is poured into the plastic bucket, the liquid will press against the bottom of the bucket, creating pressure. Simultaneously, the bottom of the bucket will squeeze the reinforcing buffer plate 3. The reinforcing buffer plate 3 then moves via the connecting post 5, causing the insertion rod 6 to slide relative to the connecting post 5 and compress the buffer spring 7. Under the restoring force of the buffer spring 7, the reinforcing buffer plate 3 receives a buffering force, and the bottom of the plastic bucket also receives a buffering force. This effectively reduces the pressure of the liquid on the bottom of the plastic bucket. Furthermore, adjusting the restoring force of the spring 11 will also buffer the side wall of the plastic bucket, making the bottom of the bucket more stable and improving its reinforcement effect. This ensures that the auxiliary fixing plate 2 stably presses against and fixes the plastic bucket while greatly increasing the buffering force, enhancing the reinforcement effect of the bottom of the plastic bucket, and improving the practicality of the device.
[0032] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
