Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic bucket technology, specifically a double-mouth, double-lid plastic bucket. Background Technology
[0002] Plastic drums are widely used for the storage and transportation of various liquids. They have excellent properties for packaging special hazardous materials, such as being unbreakable, rust-free, and lightweight. They also have excellent oil resistance and strong corrosion resistance, and are often used for packaging hazardous materials that require heat preservation, moisture protection, pressure resistance, and corrosion resistance.
[0003] Traditional plastic buckets have the following drawbacks in terms of functionality and practicality:
[0004] Functionality limitation: The single-port design results in slow loading speed and lacks a flow guide when pouring liquids, which easily leads to splashing and waste.
[0005] Insufficient stability: The cylindrical barrel is prone to rolling and tipping, posing a significant risk, especially during transportation or on slopes; the bottom lacks a reinforcing structure, limiting its load-bearing capacity.
[0006] Low handling efficiency: Large-capacity containers require multiple people to move them, and there is no labor-saving design, resulting in high labor costs.
[0007] Inconvenient maintenance: Metal fasteners are prone to corrosion, difficult to disassemble, and have high cleaning and maintenance costs. Utility Model Content
[0008] The purpose of this utility model is to provide a double-mouth, double-lid plastic bucket to solve the problems mentioned in the background art.
[0009] To achieve the above objectives, this utility model provides the following technical solution: a double-mouth, double-lid plastic bucket, comprising a bucket body, with bucket mouths at both ends of the top of the bucket body, and bucket lids movably mounted on the top of each of the two bucket mouths, with a threaded ring fixedly mounted on the top of one of the bucket lids, and a transparent curved tube movably mounted on the threaded ring, a support step fixedly mounted near the bottom of the bucket body, and a guardrail movably mounted on the top of the support step, with plastic rolling rods mounted on the front, back, left, and right sides of the guardrail.
[0010] A recess is provided in the middle of the top of the barrel, and a handle is fixedly installed in the recess.
[0011] The number of plastic rollers is several, and the top and bottom of the plastic rollers are rotatably connected to the guardrail via connecting rods.
[0012] The guardrail and the support steps are fixedly connected by plastic fastening bolts, and the bottom of both the guardrail and the support steps are provided with several fastening holes that match the plastic fastening bolts.
[0013] The external thread of the threaded ring is consistent with the external thread of the barrel opening, and the transparent bent tube is threadedly connected to the threaded ring.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This utility model features a standardized threaded interface for quick installation of a flow guide tube, and a transparent tube body for real-time flow monitoring, reducing spillage and splashing. It is especially suitable for viscous liquids or metering scenarios.
[0016] This utility model features a bottom support step that enhances load-bearing capacity, and the guardrail forms a ring-shaped protective structure through plastic fastening bolts.
[0017] This utility model combines the functions of "movable roller" and "anti-collision buffer". When rolling, it reduces frictional resistance and facilitates handling (saving effort). When stationary, it restrains sliding and absorbs external impacts, reducing the deformation of the barrel under pressure.
[0018] This utility model has a built-in handle in the top recess, providing a gripping fulcrum, which, together with the rolling rod, enables easy carrying by a single person.
[0019] The guardrail and support steps of this utility model can be quickly disassembled and assembled using plastic fastening bolts 7 and fastening holes 11, which facilitates cleaning or replacement of parts.
[0020] The threaded rings, fastening bolts, etc. of this utility model are all made of the same corrosion-resistant plastic material as the barrel body, thus avoiding the problem of metal corrosion.
[0021] This utility model's integrated injection molding process reduces production costs, and the PP / PE material is 100% recyclable, meeting environmental protection requirements. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-5 This utility model provides a technical solution: a double-mouth, double-lid plastic bucket, including a bucket body 1, with bucket mouths at both ends of the top of the bucket body 1, and bucket lids 5 movably mounted on the top of each of the two bucket mouths. A threaded ring 9 is fixedly mounted on the top of one of the bucket lids 5, and a transparent curved tube 6 is movably mounted on the threaded ring 9. A support step 4 is fixedly mounted near the bottom of the bucket body 1, and a guardrail 2 is movably mounted on the top of the support step 4. Plastic rolling rods 3 are mounted on the front, back, left, and right sides of the guardrail 2.
[0030] A recess 8 is provided in the middle of the top of the barrel 1, and a handle 10 is fixedly installed in the recess 8.
[0031] The number of plastic roller bars 3 is several, and the top and bottom of the plastic roller bars 3 are rotatably connected to the guardrail 2 through connecting rods.
[0032] The guardrail 2 and the support step 4 are fixedly connected by plastic fastening bolts 7, and the bottom of both the guardrail 2 and the support step 4 are provided with several fastening holes 11 that match the plastic fastening bolts 7.
[0033] The external thread of the threaded ring 9 is consistent with the external thread of the barrel opening, and the transparent bend 6 is threadedly connected to the threaded ring 9.
[0034] Threaded ring 9 and transparent bend 6: The standardized design of the threaded ring (consistent with the thread at the barrel opening) facilitates the quick installation and removal of the bend, while the transparent bend allows for real-time observation of the liquid flow and prevents liquid splashing when pouring.
[0035] Support step 4 and guardrail 2: The support step serves as a reinforcing structure at the bottom of the barrel, enhancing the overall load-bearing capacity; the guardrail is fixed to the support step by plastic fastening bolts 7, forming a ring-shaped protective frame.
[0036] Plastic Roller Rod 3: Multiple roller rods are rotatably connected to the guardrail via connecting rods, forming a "roller belt" structure. During handling, the drum can be easily moved by the contact between the roller rods and the ground. When stationary, the roller rods are restrained by the guardrail to prevent accidental slippage, and can also buffer some of the impact of blunt objects, reducing the pressure on the drum.
[0037] Plastic fastening bolts 7 and fastening holes 11: Modular assembly of guardrails and support steps is achieved through matching fastening holes. The bolt material is the same as that of the barrel (to avoid metal corrosion). The detachable design facilitates cleaning, maintenance or replacement of parts.
