Description

Technical Field

[0001] This utility model belongs to the field of craft product manufacturing technology, specifically, it relates to an anti-deformation support ring structure for the side wall of a straw basket. Background Technology

[0002] Straw baskets, as a traditional storage container, are widely used in home storage and decoration. Their sidewalls are woven from natural plant fibers, making them environmentally friendly and breathable. In traditional straw basket manufacturing, to maintain the shape stability of the basket's sidewalls, wooden or bamboo rings are typically used as an internal framework for support during the weaving process. These rings are positioned and fixed through simple interlacing with the woven fibers. However, traditional wooden or bamboo ring support structures have significant drawbacks. These natural material rings are prone to expansion or contraction deformation due to changes in environmental humidity over long-term use. Furthermore, because the rings themselves lack radial support structures, when the straw basket is loaded with heavy objects or subjected to external pressure, the rings easily undergo elliptical deformation in the radial direction, causing the entire basket's sidewalls to lose their circular outline and become irregularly shaped. In existing technology, because the traditional support ring structure lacks an effective anti-deformation mechanism and the fixed connection between it and the basket's woven fibers is not strong enough, the straw basket's sidewalls cannot maintain a stable circular shape over long-term use. In other words, existing technology presents a technical problem where the straw basket's sidewalls deform under pressure during long-term use, causing the basket to lose its original circular outline. Utility Model Content

[0003] In view of this, the present invention provides a deformation-resistant support ring structure for the side wall of a straw basket, which can solve the technical problem that the side wall of the straw basket loses its original circular outline due to pressure deformation during long-term use.

[0004] This utility model is implemented as follows:

[0005] This utility model provides an anti-deformation support ring structure for the side wall of a straw basket, comprising an annular support ring body, which is formed by bending metal wire. The annular support ring body has a circular main ring segment and multiple radial reinforcing ribs connected to the circular main ring segment. The radial reinforcing ribs extend from the inner circumference of the circular main ring segment towards the center. The multiple radial reinforcing ribs converge at the center of the circular main ring segment and connect with each other to form a central connection node. The connection between the radial reinforcing ribs and the circular main ring segment is an arc transition shape. The outer circumferential surface of the circular main ring segment is provided with multiple equally spaced snap-fit ​​protrusions, which are used to embed into the weaving gaps of the straw basket side wall to achieve a fixed connection between the support ring and the basket body.

[0006] The technical effects of the anti-deformation support ring structure for the side wall of a straw basket provided by this utility model are as follows: Through the combined structural design of the annular support ring body and the radial reinforcing ribs, a skeleton system with multi-directional support capability is formed inside the side wall of the straw basket. The radial reinforcing ribs extend from the circular main ring section towards the center and converge at the center, so that when the support ring structure is subjected to lateral compressive force, the force can be transmitted and dispersed to the central node through the radial reinforcing ribs. At the same time, the snap-fit ​​protrusions on the outer circumference of the circular main ring section are embedded in the weaving gap to realize the mechanical interlocking and fixing of the support ring and the basket body, preventing the support ring from shifting or rotating inside the basket, thereby effectively maintaining the circular contour stability of the side wall of the straw basket.

[0007] Based on the above technical solution, the anti-deformation support ring structure of the side wall of the straw basket of this utility model can be further improved as follows:

[0008] The number of radial stiffeners is 3 to 6, and the radial stiffeners are evenly distributed at an angle on the inner circumference of the circular main ring segment.

[0009] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the number of radial stiffeners is set to 3 to 6 and they are evenly distributed at an angle to ensure that the support ring structure obtains a balanced radial support force in each area in the circumferential direction, avoiding local deformation caused by insufficient support strength in some areas due to uneven distribution of stiffeners. At the same time, moderately controlling the number of stiffeners can reduce the amount of material used and manufacturing complexity while ensuring structural strength.

[0010] Furthermore, the ends of multiple radial reinforcing ribs at the central connection node are fixedly connected by welding to form an integrated rigid node structure.

[0011] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the radial stiffeners are fixedly connected at the central connection node by welding to form an integrated rigid node, which enables multiple radial stiffeners to constrain and transmit force to each other. When the radial stiffeners in any direction are subjected to external force, the stiffeners in other directions can provide reverse support force through the rigid node, which significantly improves the overall deformation resistance and structural stability of the support ring.

[0012] Furthermore, the angle between the radial stiffener and the circular main ring segment is an acute angle, and the length of the radial stiffener is half the inner diameter of the circular main ring segment.

[0013] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the radial stiffener and the circular main ring segment are connected at an acute angle, which enables the stiffener to more effectively bear the radial tensile force and tangential force transmitted from the circular main ring segment. At the same time, the length of the radial stiffener is set to half of the inner diameter of the circular main ring segment, ensuring that the stiffener provides sufficient support stiffness without excessively increasing the weight, thus achieving a balance between structural strength and lightweight.

[0014] Furthermore, the snap-fit ​​protrusion is in the shape of a flat ellipse, and the snap-fit ​​protrusion is set to protrude along the radial direction of the circular main ring segment.

[0015] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the snap-fit ​​protrusion adopts a flat oval shape and is set to protrude in the radial direction. This shape design makes it easier for the protrusion to be inserted into the weaving gap of the side wall of the straw basket. At the same time, the flat oval shape forms a large contact area with the woven fibers after insertion, which enhances the reliability of snap-fit ​​and prevents the protrusion from falling out of the weaving gap during use.

[0016] Furthermore, the number of snap-fit ​​protrusions is 8 to 12, and the arc spacing between two adjacent snap-fit ​​protrusions is equal.

[0017] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: setting the number of snap-fit ​​protrusions to 8 to 12 and keeping the arc spacing between adjacent protrusions equal, forming a uniformly distributed multi-point fixed connection on the circumference of the circular main ring segment, so that the fixing force between the support ring and the side wall of the straw basket is evenly distributed in the entire circumferential direction, avoiding local loosening or displacement caused by insufficient fixing points or uneven distribution in some areas.

[0018] Furthermore, the cross-sectional shape of the circular main ring segment is circular, and the cross-sectional shape of the radial reinforcing ribs is the same as that of the circular main ring segment.

[0019] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the circular main ring segment and the radial reinforcing rib adopt the same circular cross-sectional shape, so that the entire support ring structure has consistent bending stiffness and torsional resistance in all parts, avoiding stress concentration caused by the difference in cross-sectional shape in different parts. At the same time, the same cross-section also makes it easier to use metal wire of the same specification for continuous bending processing, improving manufacturing efficiency and structural consistency.

[0020] Furthermore, the annular support ring body is made of spring steel wire, and the snap-fit ​​protrusion is formed by locally cold pressing the metal wire.

[0021] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: using spring steel wire to make the ring support body can give the support ring good elastic recovery ability and fatigue resistance. When the straw basket is squeezed and deformed during use, the support ring can rely on the elasticity of the material to restore its original shape. At the same time, the snap-fit ​​protrusion formed by cold pressing can achieve local shape shaping without damaging the internal structure of the material.

[0022] Furthermore, the radius of curvature of the arc transition shape is greater than twice the diameter of the circular main ring segment cross section.

[0023] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the radius of curvature of the arc transition shape is set to be greater than twice the diameter of the circular main ring section, so that the connection between the radial stiffener and the circular main ring section forms a smooth large arc transition, effectively reducing the stress concentration in the connection area, avoiding metal fatigue fracture at this position during repeated stress, and extending the service life of the support ring.

[0024] Furthermore, the outer contour of the central connecting node is a hexagonal structure, and radial reinforcing ribs extend radially outward from each vertex of the hexagonal structure to the circular main ring segment.

[0025] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the central connection node adopts a hexagonal outer contour structure and the radial stiffeners extend outward from each vertex. The hexagonal structure can provide a stable connection foundation and clear spatial positioning for multiple radial stiffeners. At the same time, the geometric characteristics of the hexagon ensure that the included angle between adjacent radial stiffeners remains consistent, ensuring that the mechanical properties of the support ring structure are symmetrical and balanced in all directions.

[0026] Compared with existing technologies, the beneficial effects of the anti-deformation support ring structure for the side wall of a straw basket provided by this utility model are as follows: By designing a composite skeleton structure combining a ring support ring body with multiple radial reinforcing ribs, and setting snap-fit ​​protrusions on the outer circumference of the circular main ring segment to achieve mechanical interlocking and fixation with the straw basket weaving fibers, the support ring can transmit and disperse the force to the central node through the radial reinforcing ribs when subjected to external force. At the same time, the snap-fit ​​protrusions are firmly embedded in the weaving gaps to prevent the support ring from shifting. Compared with the traditional single ring support structure, the radial reinforcing ribs of this utility model extend from the circular main ring segment towards the center and converge at the center to form a rigid connection node, constructing a multi-directional radial support system. When the straw basket is subjected to lateral compressive force, the radial reinforcing ribs can effectively resist the elliptical deformation tendency of the circular main ring segment. At the same time, the use of spring steel wire material instead of traditional wood or bamboo materials eliminates the problem of dimensional instability caused by changes in environmental humidity. The snap-fit ​​protrusions on the outer circumference significantly enhance the bonding strength between the support ring and the basket body by embedding them into the weaving gaps to achieve multi-point fixed connection. In summary, this utility model solves the problem of insufficient deformation resistance of traditional straw basket sidewall support structures by combining the annular support ring body with radial reinforcing ribs and using a snap-fit ​​protrusion fixing mechanism. This allows the straw basket sidewall to maintain a stable circular outline even under long-term use and pressure, thus solving the technical problem mentioned in the background art where the straw basket sidewall loses its original circular outline due to pressure deformation during long-term use.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0034] like Figures 1-3The image shows an embodiment of an anti-deformation support ring structure for the side wall of a straw basket provided by this utility model. This utility model provides an anti-deformation support ring structure for the side wall of a straw basket, which mainly consists of an annular support ring body 10. The annular support ring body is made of spring steel wire with a diameter of 2mm to 4mm through a bending and forming process, and the entire support ring body presents a planar annular structure. The annular support ring body includes a circular main ring segment 11 and multiple radial reinforcing ribs 12. The circular main ring segment forms the outer contour of the support ring, and its inner diameter is determined according to the specifications of the straw basket, typically within the range of 150mm to 300mm. The cross-section of the circular main ring segment is circular, and its diameter is consistent with the diameter of the metal wire used. The number of radial reinforcing ribs is 3 to 6, and these radial reinforcing ribs are evenly distributed on the inner circumference of the circular main ring segment. Each radial reinforcing rib extends straight from the inner circumference of the circular main ring segment towards the center, and the length of the radial reinforcing rib is half the inner diameter of the circular main ring segment, so that the ends of all radial reinforcing ribs can converge at the center. At the center, the ends of multiple radial stiffeners are fixedly connected to each other by argon arc welding or resistance welding to form a central connection node 13. The central connection node has a hexagonal outer contour, with each vertex of the hexagon corresponding to the connection point of a radial stiffener. The diameter of the welded node is approximately 6mm to 10mm, and the welded area forms a rigid, integrated connection to ensure that the radial stiffeners can transmit force to each other. An arc transition section 15 is provided at the connection between the radial stiffener and the circular main ring segment. The radius of curvature of the arc transition section is 5mm to 8mm, which is more than twice the diameter of the circular main ring segment. This large arc transition design avoids sharp turning angles at the connection between the radial stiffener and the circular main ring segment, reducing stress concentration at this location. Eight to twelve snap-fit ​​protrusions 14 are evenly arranged along the circumferential direction on the outer circumferential surface of the main circular ring segment. The snap-fit ​​protrusions are formed by local cold pressing of the metal wire. Each snap-fit ​​protrusion is flat and elliptical in shape, with its major axis arranged radially along the main circular ring segment. The major axis dimension of the snap-fit ​​protrusion is 3mm to 5mm, the minor axis dimension is 1.5mm to 2.5mm, and the protrusion height is 1mm to 2mm. The arc spacing between two adjacent snap-fit ​​protrusions 05 is equal to ensure a uniform distribution of fixing points in the circumferential direction.

[0035] During use, the completed ring support body is placed inside the side wall of the straw basket at a predetermined height, usually at the middle or upper third of the side wall height. The outer circumference of the main circular ring is then pressed tightly against the inner surface of the side wall, aligning the interlocking protrusions with the natural gaps between the woven fibers. Slight pressure on the main circular ring allows the interlocking protrusions to be inserted one by one into the weave gaps. Because the interlocking protrusions are flat and elliptical in shape and protrude radially, they can easily pass through the warp and weft intersections of the woven fibers and enter the gaps. Once all the interlocking protrusions are fully embedded, a multi-point mechanical interlocking connection is formed between the support body and the side wall of the straw basket. When the straw basket is loaded with items or subjected to external pressure, the radial inward pressure on a certain area of ​​the circular main ring segment is transmitted to the radial reinforcing ribs connected to that area. These reinforcing ribs then transmit the force to the central connecting node. Since the central connecting node is a rigid welded structure, the transmitted force is dispersed to the radial reinforcing ribs in other directions. These reinforcing ribs, through the arc transition section, apply the reverse support force back to the corresponding position of the circular main ring segment, forming a closed-loop force transmission. This allows the circular main ring segment to maintain its circular outline and avoid elliptical deformation under stress. At the same time, the snap-fit ​​protrusions, after being embedded in the weaving gaps, form frictional and compressive contact with the weaving fibers, preventing the support ring body from rotating or axially sliding within the basket. This ensures that the support ring's supporting effect continues to act effectively on the side wall of the basket, thereby achieving long-term stable support for the shape of the straw basket's side wall.

[0036] The following is a specific embodiment 1: The annular support ring body is made using 3mm diameter 65Mn spring steel wire as the raw material. First, the wire is cold-bent into a circular main ring segment with an inner diameter of 200mm using a special circular fixture. Then, six evenly distributed connection points are marked on the inner circumference of the main ring segment, with a central angle of 60 degrees between any two adjacent connection points. Six 100mm long steel wires of the same specification are bent into straight lines to serve as the raw material for radial reinforcing ribs. At each connection point, one end of a radial reinforcing rib is welded to the inner circumference of the main ring segment using argon arc welding. During welding, the current and welding time are controlled to create a large arc transition of 5mm to 8mm at the weld point, rather than a sharp corner connection. The other ends of the six radial reinforcing ribs converge at the center of the main ring segment, and the ends of the six reinforcing ribs are welded together using multi-point welding to form a hexagonal central connection node with a diameter of approximately 8mm. After welding, the weld points are ground to remove weld beads and ensure a smooth node surface. Next, 10 equally spaced cold-pressing points are marked on the outer circumference of the main circular ring segment. The arc length between each point is approximately 62.8 mm. A specialized cold-pressing mold is used to locally press each marked point. The mold's pressure head is a flat, elliptical groove. By controlling the pressing depth, a flat, elliptical locking protrusion with a major axis of 4 mm, a minor axis of 2 mm, and a height of 1.5 mm is formed at that location on the main circular ring segment. All locking protrusions are arranged radially along their major axes. After cold pressing, the entire support ring body undergoes surface rust prevention treatment, which can be achieved by galvanizing or spraying with rust-preventive paint. The treated support ring body has a silver-white or gray appearance. The completed support ring was placed inside a cylindrical straw basket with an inner diameter of 2mm, an outer diameter of 220mm, and a height of 180mm. The support ring was positioned 120mm above the side wall of the basket, ensuring the outer circumference of the main circular ring was flush against the inner wall. Ten interlocking protrusions were then inserted sequentially into the weave of the straw fibers through even pressure, to a depth of approximately 8mm to 12mm. This created a stable mechanical connection between the support ring and the side wall of the straw basket. A test was conducted by placing 8kg of items inside the basket. The lateral pressure from the stacked items acted on the side wall of the basket. After 30 days of continuous use, the side wall profile of the straw basket was measured. The basket maintained its circular shape, with the radius deviation at any point on the side wall controlled within 3mm. No significant deformation or displacement of the support ring was observed.

[0037] The following is a specific embodiment 2: This embodiment improves upon embodiment 1 by using 2.5mm diameter spring steel wire to make the radial reinforcing ribs, thus reducing the overall weight. The number of radial reinforcing ribs is increased to eight, reducing the central angle between adjacent ribs to 45 degrees, thereby providing a denser radial support distribution in the circumferential direction. An octagonal outer contour structure is used at the central connection node, with each vertex corresponding to the connection position of a radial reinforcing rib. The circumcircle diameter of the octagonal node is 10mm. This improved structure is applied to a small straw basket with an inner diameter of 180mm. The total weight of the support ring body is reduced by approximately 15% compared to embodiment 1. Furthermore, the denser distribution of the radial reinforcing ribs makes the support ring's support on the circular main ring segment more uniform. Under the same external force, the radial deformation at various positions of the circular main ring segment is more consistent, further improving the overall structure's resistance to deformation and stability.

[0038] The following is a specific embodiment 3: This embodiment optimizes and improves the shape and distribution of the snap-fit ​​protrusions based on embodiment 1. The number of snap-fit ​​protrusions is increased to 16, reducing the distance between adjacent protrusions to approximately 39.3 mm. Simultaneously, the shape of each snap-fit ​​protrusion is changed to a triangular pyramid shape, with a base length of 3 mm and a height of 2 mm, and the tip of the pyramid pointing radially outward. This triangular pyramid shape provides better guidance and wedging effect when inserted into the weaving gaps of the straw fibers. The three inclined surfaces of the protrusion form multi-directional contact with the woven fibers, increasing friction and pull-out resistance. Furthermore, the increased number of fixing points to 16 makes the connection between the support ring body and the basket sidewall more robust. Even when the straw basket is subjected to significant impact or falls, the support ring body can remain in its original position without detachment or displacement. This improved structure is particularly suitable for straw baskets that require frequent movement or handling.

[0039] Specifically, the principle of this invention is as follows: A multi-directional support system constructed with radial reinforcing ribs effectively suppresses the deformation tendency of the circular main ring segment under stress. When the sidewall of the straw basket is subjected to external compressive force, the radial internal pressure generated in a certain area of ​​the circular main ring segment is transmitted to the central connection node through the radial reinforcing ribs connected to that area. Since multiple radial reinforcing ribs form a rigid connection at the central node, this node can distribute the transmitted force to the radial reinforcing ribs in other directions. These reinforcing ribs, in turn, provide reverse support force outward through their connection points with the circular main ring segment, thus forming a closed-loop transmission and balance mechanism of force within the entire support ring structure. Simultaneously, the snap-fit ​​protrusions, embedded in the gaps between the straw basket's woven fibers, form a mechanical engagement with the fibers. When the support ring is subjected to deformation force, the snap-fit ​​protrusions, through friction and compression with the woven fibers, firmly fix the support ring to a predetermined position on the sidewall of the basket, preventing rotation or axial displacement within the basket. This ensures that the support of the support ring can be continuously and effectively applied to the circumferential direction of the basket's sidewall. This fixing mechanism, combined with the support of the radial reinforcing ribs, forms a dual protection system. Furthermore, the use of spring steel wire to make the support rings allows the structure to undergo elastic deformation without permanent damage when subjected to a large instantaneous external force. After the external force is removed, the support rings return to their original shape due to the elastic restoring force of the material itself. This material characteristic, together with the rigid support of the radial reinforcing ribs, ensures that the side wall of the straw basket maintains a stable circular profile under various operating conditions. It is based on these mutually complementary structural designs and mechanical principles that this utility model can fundamentally solve the deformation problem of the side wall of the straw basket.
