Description

Technical Field

[0001] This utility model relates to the field of packaging container technology, specifically to a semi-circular ring lifting ring. Background Technology

[0002] In the packaging industry, large-capacity liquid containers such as bottled water and bottled oil are usually equipped with lifting rings for easy handling. Figure 1-2 The image shows a common lifting ring 200 on the market. The lifting ring 200 is made of plastic through one-time injection molding. Its structure includes two parts: a ring and a handle. The two ends of the handle are fixed to the outer side of the ring with an arc structure, and the ring and the handle are on the same plane.

[0003] for Figure 1-2 The inventors believe that the lifting ring 200 shown has significant defects in actual use: when the user lifts the cylinder through the lifting ring, the handle bends under the action of gravity, changing from the initial planar state to a position perpendicular to the ring; due to the elastic properties of the plastic material, the handle will generate a reverse elastic force and act on the fingers, resulting in a strong feeling of tightness and pressure discomfort, and may even cause finger fatigue or injury.

[0004] Therefore, the inventors believe that how to solve the above-mentioned technical problems is a technical problem that needs to be solved in the field of packaging container technology.

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] See Figures 1-6 To address the problems mentioned in the background section, this utility model provides a semi-circular ring lifting ring to solve the aforementioned technical problems. The technical solution is as follows:

[0027] A semi-circular ring lifting ring includes: a circular ring component 320 and two lifting ring components 310 connected to the circular ring component 320;

[0028] A number of first cards 330 arranged in a circular array are fixedly connected to the side of the inner ring of the circular component 320; the first cards 330 face the inner side of the circular component 320 and are inclined upward.

[0029] A fixing seat 340 is fixedly connected to each side of the ring component 320, and the fixing seat 340 has two spaced connecting holes 341.

[0030] The lifting ring component 310 includes a handle 312 and lifting arms 311 fixed on both sides of the handle 312;

[0031] A fixed shaft 313 is fixed to the inner side of the end of the lifting arm 311, and a number of second cards 314 arranged in a circular array are fixedly connected to the end of the fixed shaft 313; the free ends of the second cards 314 are inclined towards the outside of the fixed shaft 313.

[0032] Among them, the two fixed shafts 313 on the lifting ring component 310 are respectively inserted into the connecting holes 341 of the two side fixed seats 340, and the second card 314 at the end of the fixed shaft 313 passes through the connecting hole 341 and is located inside the fixed seat 340.

[0033] It should be noted that the lifting ring adopts a separate structure of the circular ring component and the lifting ring component. By simplifying the mold design, the difficulty of the injection molding process is reduced. At the same time, a fixed shaft and a second clip are set at the end of the lifting arm. By utilizing the plastic elastic snap-fit ​​principle, the lifting ring component and the circular ring component can be quickly assembled, taking into account both structural reliability and process convenience.

[0034] In this embodiment, the ring component 320, the first card 330, and the fixing seat 340 are integrally injection molded; the handle 312, the lifting arm 311, the fixing shaft 313, and the second card 314 are integrally injection molded.

[0035] In this embodiment, the inner side of the grip 312 is provided with a plurality of arc-shaped grooves that cooperate with the fingers.

[0036] In this embodiment, the lifting arm 311 is provided with reinforcing ribs on its side.

[0037] The present invention provides a method for lifting a semi-circular ring as follows:

[0038] I. Installation Stage: Quick-connect fixing with cylinder 100

[0039] (1) Positioning of the ring component: Align the ring component 320 with the bottle mouth of the cylinder 100, and press the first card 330 of the inner ring upward and downward. Since the first card 330 is tilted upward and has plastic elasticity, when the ring component 320 is pressed, the card first deforms, passes the edge of the bottle mouth of the cylinder 100 and returns to its original shape. It is clamped to the inside of the bottle mouth through the "barrel" structure, so as to realize the fixed connection between the lifting ring and the cylinder 100.

[0040] (3) Assembly of lifting ring component: The fixed shaft 313 of the lifting ring component 310 is aligned with the connecting hole 341 of the fixed seat 340. When it is forcefully inserted, the second card 314 is elastically compressed due to the inclined design. After passing through the connecting hole, it opens and is clamped on the inside of the fixed seat 340, completing the rotational connection between the lifting ring component and the ring component 320. At this time, the lifting ring component can rotate freely around the fixed shaft.

[0041] II. Handling Stage: Mechanical Transmission During Load Bearing

[0042] (1) Initial state when lifting the cylinder 100: The user holds the handle 312 to lift the cylinder 100, and the weight of the cylinder 100 is transferred to the ring component 320 through the lifting ring component 310.

[0043] (2) Rotation of the lifting ring component to release force: The handle of a traditional lifting ring will be forced to bend at this stage. However, in this design, the lifting ring component 310 rotates naturally around the fixed axis 313 due to gravity, changing from the initial plane state to a posture perpendicular to the ring component. During the rotation, the elasticity of the plastic material is no longer used to resist bending, but to release stress through angle adjustment, avoiding the handle from generating a reverse elastic force on the fingers.

[0044] (3) At the same time, since a lifting ring component 310 is provided on each side of the ring component 320, when the cylinder 100 is lifted, the user can grasp the two handles 312 with his / her hands, which increases the hand area with the fingers, further reduces the tightness of the fingers, and improves comfort.

[0045] The semi-circular ring lifting ring provided by this utility model has the following beneficial effects: Through the innovative cooperation of various structures, this utility model effectively solves the problem of discomfort caused by the tight grip of fingers when using traditional lifting rings, and improves the user's grip comfort; by adopting a separate structure of the circular ring component and the lifting ring component, the process difficulty of injection molding is simplified; a fixed shaft and a second clip are set at the end of the lifting arm, and the lifting ring component and the circular ring component are quickly assembled by utilizing the plastic elastic snap-fit ​​principle, taking into account both structural reliability and process convenience.
