Technical Field

[0001] This utility model relates to the field of resin crafts technology, specifically to a lightweight hollow resin craft core structure. Background Technology

[0002] The main function of the inner core of hollow resin crafts is to reduce costs and control weight, while also helping to ensure the structural stability and molding effect of the product. Hollow resin currently provides support and stability for handicrafts. To prevent the support of hollow resin from decreasing, it is often made into a solid form to increase its strength. However, while increasing the strength of hollow resin, using a solid form also increases its weight, resulting in a heavier handicraft when it is used inside.

[0003] Therefore, we proposed a lightweight hollow resin craft core structure that can effectively solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a lightweight hollow resin craft core structure to solve the problem mentioned in the background art that the current market use of solid materials increases the strength of hollow resin but also increases its weight, which in turn increases the weight of the craft when hollow resin is used inside the craft, resulting in a heavier craft.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lightweight hollow resin craft core structure, comprising a craft body, wherein a resin core is snapped into the bottom of the craft body; The resin core has a through hole inside, which penetrates the resin core. The outer wall of the resin core has a limiting groove at an equal angle, and the inside of the limiting groove and the craft body form a snap-fit ​​connection mechanism.

[0006] Preferably, the inner wall of the resin core is fused with a connecting plate, and the connecting plate is provided in three sets, with the three sets of connecting plates arranged at equal angles.

[0007] Preferably, the inner end of the connecting plate is fused to the outer wall of the reinforcing rib, and the reinforcing rib is made of resin material.

[0008] Preferably, hollow microspheres are added to the resin core, and the hollow microspheres are added at 15% of the resin core usage ratio.

[0011] Preferably, azodicarbonamide is added to the resin core, and the azodicarbonamide is added at 2% of the resin core usage ratio.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the lightweight hollow resin craft core structure is lighter and stronger; the use of through holes further reduces the overall weight of the resin core, thereby achieving weight reduction; and the use of connecting plates improves the strength of the resin core. The specific details are as follows: (1) It is provided with through holes. By using through holes, the resin core is hollowed out. Therefore, the overall weight of the resin core can be reduced by hollowing out, thus making the resin core lighter. (2) A connecting plate is provided. By using the connecting plate, the connecting plate can support the resin core, thereby improving the strength of the resin core. (3) It is equipped with reinforcing ribs, which are fused to the outer wall of the reinforcing ribs through the inner end of the connecting plate. The reinforcing ribs are made of resin material, and the strength of the resin core can be further improved by the use of the reinforcing ribs. (4) Hollow microspheres are provided. Hollow microspheres are added to the resin core, and the amount of hollow microspheres added is 15% of the resin core usage ratio.

[0015] 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.

[0016] Example 1: A lightweight hollow resin craft core structure solves the problem that while existing solid methods increase the strength of hollow resin, they also increase its weight, leading to a heavier craft when used inside. The use of through holes 5 allows the resin core 2 to achieve a lightweight effect. The following is disclosed: The bottom of the craft body 1 is snapped with a resin core 2; the inside of the resin core 2 is provided with a through hole 5, and the through hole 5 penetrates the resin core 2; and the outer wall of the resin core 2 is provided with a limiting groove 6 at equal angles, and the inside of the limiting groove 6 and the craft body 1 form a snap-fit ​​connection mechanism. refer to Figures 1 to 3 The top of the resin core 2 is inserted and connected to the craft body 1, which can play a role in installing and fixing the craft body 1. The use of through hole 5 allows the interior of the resin core 2 to be hollowed out. The hollowing out method can reduce the overall weight of the resin core 2, thus making the resin core 2 lightweight.

[0017] Example 2: A lightweight hollow resin craft core structure solves the problem of poor strength of the resin core 2 in Example 1. The strength of the resin core 2 can be improved by using a connecting plate 3. The following is disclosed: The inner wall of the resin core 2 is fused with a connecting plate 3, and there are three sets of connecting plates 3. The three sets of connecting plates 3 are arranged at equal angles. The inner end of the connecting plate 3 is fused to the outer wall of the reinforcing rib 4, and the reinforcing rib 4 is made of resin material. refer to Figures 1 to 3The use of connecting plate 3 can improve the strength of resin core 2, thereby giving resin core 2 strong resistance to bending. The use of connecting plate 3 can also fix reinforcing rib 4 inside resin core 2, thereby further improving the strength of resin core 2. The use of limiting groove 6 can also make it snap-fit ​​with the craft body 1, thereby facilitating the connection of the craft body 1.

[0018] Example 3: A lightweight hollow resin craft core structure solves the problem of poor lightweighting of the resin core 2 in Example 1. By using hollow microspheres 201, the weight of the resin core 2 can be further reduced, thereby further improving the lightweighting effect. The following is disclosed: Hollow microspheres 201 are added to the resin core 2 at 15% of the usage ratio of the resin core 2. Short-cut glass fibers 202 are added to the resin core 2 at 20% of the usage ratio of the resin core 2. Light calcium carbonate 203 is added to the resin core 2 at 10% of the usage ratio of the resin core 2. Azodicarbonamide 204 is added to the resin core 2 at 2% of the usage ratio of the resin core 2. refer to Figures 3 to 5 By adding hollow microspheres 201 into the resin core 2, air bubbles can be generated inside the resin core 2. These air bubbles reduce the mass of the resin core 2, thus reducing its weight. The addition of chopped glass fibers 202 can both increase and decrease the strength of the resin core 2. The use of lightweight calcium carbonate 203 reduces the amount of resin core 2 required, allowing for production with lower dosage and thus reducing the mass of the resin core 2. The use of azodicarbonamide 204, which generates nitrogen gas upon heating, makes the air bubbles within the resin core 2 more uniform, thereby improving the aesthetics of the air bubbles within the resin core 2.

[0019] Working principle: When using this lightweight hollow resin craft core structure, firstly, refer to... Figures 1 to 3 The top of the resin core 2 is inserted and connected to the craft body 1. The use of the through hole 5 allows the interior of the resin core 2 to be hollowed out, thus making the resin core 2 lighter.

[0020] refer to Figures 1 to 3By using the connecting plate 3, the strength of the resin core 2 can be improved, thus giving the resin core 2 strong resistance to bending. Furthermore, the connecting plate 3 can fix the reinforcing rib 4, thereby further improving the strength of the resin core 2 and facilitating its connection to the main body 1 of the craft.

[0021] refer to Figures 3 to 5 By adding hollow microspheres 201 into the resin core 2, air bubbles can be generated inside the resin core 2, thus reducing the weight of the resin core 2. The addition of chopped glass fibers 202 can also reduce the strength of the resin core 2. The use of lightweight calcium carbonate 203 allows the resin core 2 to be produced in a lower dosage. The use of azodicarbonamide 204 allows nitrogen gas to be generated when heated, making the air bubbles inside the resin core 2 more uniform.
