Description

A boxing target and its production method Technical Field

[0001] The present invention relates to the technical field of sports equipment, in particular to a boxing target and a production method thereof. Background Art

[0002] Boxing is a sport in which fighting is performed while wearing boxing gloves; students usually need to use a boxing target when practicing boxing.

[0003] In order to guide students to conduct flexible reaction training, coaches usually wear handheld boxing targets. By wearing the boxing targets on their hands, coaches can flexibly change different positions to guide students to conduct training during training. For example, the Chinese utility model patent with application number CN201721263383.7 discloses a high-performance boxing target with protective effect, which includes a boxing target body, which is composed of a buffer plate and a buffer box, and a first buffer layer is arranged on the buffer plate, the buffer box is formed as a whole with the fixing seat, and a sliding block is arranged between the buffer box and the buffer plate, a second buffer layer is embedded in the fixing seat, and a handheld Velcro is fixedly installed on the fixing seat. The boxing target realizes double-layer protection by providing the first buffer layer and the second buffer layer, and is provided with a buffer plate and a buffer box. The two cooperate with each other to convert the frontal impact force generated by the student's punch into lateral force, thereby greatly reducing the frontal impact force received by the coach, and effectively preventing the coach's wrist, elbow and shoulder from being injured.

[0004] In actual boxing training, punches are often aimed at multiple parts of the human body (such as the head and abdomen). However, the structure of existing wearable boxing targets differs significantly from the human body. This means that trainees do not experience the sensation of physical impact during training, resulting in a poor punching experience and poor training results. In light of this issue, the inventors conducted in-depth research, leading to the creation of this case. Technical issues

[0015] In a second aspect, a method for producing a boxing target comprises the following steps:

[0016] Step S1: pre-manufacture an inner support body and a handpiece, wherein the inner support body is provided with a perfusion opening;

[0017] Step S2: placing the inner support body into a rotational molding mold, adding material components into the rotational molding mold, and forming an elastic surface layer on the outside of the inner support body through a rotational molding process, so that a filling cavity is formed between the inner support body and the elastic surface layer, and the filling cavity is connected to the injection opening;

[0018] Step S3: Install the handpiece onto the inner support body, and pour the elastic foam filling material into the filling chamber through the pouring opening, so that the elastic foam filling material is foamed and formed into an elastic foam layer in the filling chamber.

[0021] By adopting the technical solution of the present invention, at least the following beneficial effects are achieved:

[0022] 1. The elastic surface layer is rotationally molded on the outside of the inner support body by a rotational molding process, so that a filling cavity is formed between the inner support body and the elastic surface layer, and an elastic foam layer is formed in the filling cavity by foaming the elastic foam filler. The entire boxing target has a three-layer structure, among which the elastic surface layer located on the outermost side and the elastic foam layer located in the middle layer are both elastic. The inner support body located in the innermost layer can provide stable support for the elastic surface layer and the elastic foam layer. Therefore, the entire boxing target is similar to the structure of the human body. When the trainer hits it, he feels like he is hitting the human body, which can enhance the hitting experience.

[0023] 2. By designing the inner support body to imitate the human skull structure and the elastic surface to imitate the human face skin, the final boxing target is extremely similar to the real human head structure. Among them, the inner support body is equivalent to the bone structure of the human head, the elastic surface is equivalent to the skin structure of the human head, and the elastic foaming layer is equivalent to the muscle and fat structure of the human head. Therefore, the trainer can simulate hitting the human head very well during training, and can give the trainer a feeling of hitting a real human head, which can effectively improve the training effect and hitting experience.

[0024] 3. By forming an assembly cavity with an opening facing downward on the inner support body and arranging the hand piece in the assembly cavity, the weight of the entire boxing target can be reduced, and it is convenient for the coach to firmly grasp the boxing target through the hand piece, so that the coach can change different positions through hand movements, thereby guiding students to flexibly learn various attack techniques (such as left and right straight punches, left and right uppercuts, left and right swing punches, kicks, etc.).

[0025] 4. By designing the handpiece as a hollow structure, and providing plug-in columns and limit blocks at both ends of the handpiece, and correspondingly providing plug-in holes and limit grooves on the cavity wall of the assembly cavity, after the two ends of the handpiece are assembled with the inner support body, the handpiece can be effectively limited by utilizing the plug-in columns and the plug-in holes, as well as the limit blocks and the limit grooves, and the elastic foam filling material can enter the interior of the handpiece for foaming molding, thereby effectively improving the connection strength between the handpiece and the inner support body, ensuring that the handpiece will not separate from the inner support body during use.

[0026] 5. By forming an extension portion at the lower end edge of the inner support body and sealing the edge of the extension portion with the elastic surface layer during rotational molding, a better accommodating space can be formed between the inner support body and the elastic surface layer. In this way, the elastic foam layer and the elastic surface layer will be more elastic when combined together, which can further enhance the sense of hitting. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In order to better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0043] It should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inside," "outside," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of these embodiments and simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. In addition, the terms "first," "second," and the like are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features defined as "first," "second," and the like may explicitly or implicitly include one or more of such features.

[0044] 1 to 7 , a boxing target 100 according to the present invention includes an inner support body 1, a handpiece 2, an elastic surface layer 3, and an elastic foam layer 4. The handpiece 2 is mounted on the inner support body 1, so that a trainer can hold the boxing target 100 in their hand through the handpiece 2 and change different positions through hand movements, thereby guiding trainees to perform flexible training.

[0045] The elastic surface layer 3 is rotationally molded on the outside of the inner support body 1, and a filling chamber 5 is formed between the inner support body 1 and the elastic surface layer 3; the inner support body 1 is provided with a pouring opening 11 connected to the filling chamber 5, and the elastic foam layer 4 is foamed in the filling chamber 5 by an elastic foam filler, and the elastic foam filler is poured into the filling chamber 5 through the pouring opening 11. Since the elastic surface layer 3 has skin-like elasticity and a filling cavity 5 is required to be formed between the inner support body 1 and the elastic surface layer 3, the elastic surface layer 3 needs to be formed on the outside of the inner support body 1 by rotational molding during manufacturing. Rotational molding, also known as rotational molding, rotational molding, rotational molding, etc., is a thermoplastic plastic hollow molding method. This method is to first add raw materials into a rotational molding mold, and then the rotational molding mold is continuously rotated along two vertical axes and heated. Under the action of gravity and heat energy, the raw materials in the rotational molding mold are gradually and evenly coated, melted and adhered to the entire surface of the mold cavity, thereby forming into the desired shape, and then cooled and shaped to obtain the product. The elastic foam filler can be made of commonly used materials on the market (such as polyurethane high-resilience sponge foam). When the present invention is implemented, it is only necessary to pour the purchased elastic foam filler through the pouring opening 11 into the filling cavity 5 between the inner support body 1 and the elastic surface layer 3 for foaming molding.

[0046] The present invention adopts a rotational molding process to rotationally mold an elastic surface layer 3 on the outside of the inner support body 1, so that a filling chamber 5 is formed between the inner support body 1 and the elastic surface layer 3, and an elastic foam layer 4 is formed in the filling chamber 5 by foaming the elastic foam filler. The entire boxing target 100 thus obtained includes a three-layer structure, wherein the elastic surface layer 3 located on the outermost side and the elastic foam layer 4 located in the middle layer are both elastic, and the inner support body 1 located in the innermost layer can provide stable support for the elastic surface layer 3 and the elastic foam layer 4. Therefore, the entire boxing target 100 is relatively similar to the structure of the human body, and the trainee has a feeling of hitting the human body when hitting, which can enhance the hitting experience.

[0047] As a specific embodiment of the present invention, the elastic surface layer 3 is made of a human face-like structure, and the inner support body 1 is made of a human skull-like structure. In a specific embodiment of the present invention, by designing the inner support body 1 to be a human skull-like structure and the elastic surface layer 3 to be a human face-like structure, the final boxing target 100 is extremely similar to the structure of a real human head. In particular, the inner support body 1 is equivalent to the bone structure of the human head, the elastic surface layer 3 is equivalent to the skin structure of the human head, and the elastic foam layer 4 is equivalent to the muscle and fat structure of the human head. Therefore, during training, the trainee can well simulate hitting the human head and can give the trainee the feeling of hitting a real human head, which can effectively improve the training effect and hitting experience. Of course, the above is only a specific embodiment of the present invention, but the present invention is not limited to this. In specific implementations, the inner support body 1 can also be made of a bone structure that imitates other parts of the human body or an animal bone structure, and the elastic surface layer 3 can also be made of an epidermal structure that imitates other parts of the human body or an animal epidermal structure.

[0048] In the present invention, to make the elastic surface layer 3 more similar to human skin structure and thus enhance the striking feel, the elastic surface layer 3 comprises the following components by weight: 2-3 parts heat-resistant agent, 4-5 parts stabilizer, 2-4 parts softener, 65-75 parts oil, and 75-85 parts polyvinyl chloride paste resin. More specifically, the heat-resistant agent is R39, the stabilizer is 1934, the softener is 2050, the oil is dibutyl oil, and the polyvinyl chloride paste resin is a dispersion of a paste-like PVC powder in a non-volatile plasticizer. The heat-resistant agent improves the material's heat resistance, ensuring that the elastic surface layer 3 can bond to the edge of the extension portion 13 during rotational molding; the stabilizer enhances the material's stability; and the softener softens the material, ensuring that the resulting elastic foam layer 4 is highly elastic.

[0049] In the present invention, a downward-opening assembly cavity 12 is formed within the inner support body 1; a plug-in post 21 is provided at each end of the handpiece 2, and a plug-in hole 121 is provided in the wall of the assembly cavity 12. The plug-in post 21 is inserted into the elastic foam layer 4 through the plug-in hole 121. By forming the downward-opening assembly cavity 12 on the inner support body 1 and arranging the handpiece 2 within the assembly cavity 12, the present invention not only reduces the weight of the entire boxing target 100, but also facilitates the trainer to securely grasp the boxing target 100 through the handpiece 2, allowing the trainer to change positions through hand movements, thereby guiding students to flexibly learn various attack techniques (such as left and right straight punches, left and right uppercuts, left and right swinging punches, kicks, etc.); at the same time, the plug-in posts 21 at both ends of the handpiece 2 are inserted into the elastic foam layer 4 through the plug-in holes 121 formed in the wall of the assembly cavity 12, thereby better connecting the handpiece 2 to the inner support body 1.

[0050] More specifically, the handpiece 2 is a hollow structure, and the free end of each of the plug-in columns 21 is provided with a connecting opening 211 connected to the filling chamber 5, so that the elastic foam filler can enter the interior of the handpiece 2 through the connecting opening 211; the filling chamber 5 and the interior of the handpiece 2 are foamed into one piece by the elastic foam filler to form the elastic foam layer 4, that is, the elastic foam layer 4 can cover the space of the filling chamber 5 and the internal space of the handpiece 2.

[0051] More specifically, both ends of the handpiece 2 are provided with a limit block 22, and the plug-in column 21 is provided on the free end surface of the limit block 22; the cavity wall of the assembly cavity 12 forms a limit groove 122, and the limit groove 122 extends downward to the bottom of the inner support body 1, and the limit block 22 is assembled in the limit groove 122. When assembling the handpiece 2 of the present invention, it is necessary to insert the plug-in column 21 at both ends of the handpiece 2 into the plug-in hole 121 provided on the assembly cavity 12, and to retain the limit block 22 in the limit groove 122. Then, an elastic foam filler is poured into the space between the inner support body 1 and the elastic surface layer 3, as well as into the interior of the handpiece 2, through the pouring opening 11. The elastic foam filler is foamed and formed between the inner support body 1 and the elastic surface layer 3, as well as into the interior of the handpiece 2 to form an elastic foam layer 4. Preferably, the handpiece 2 can be made of a rod-shaped plastic part, and the outer wall of the handpiece 2 can be formed with a concave-convex structure to increase the friction when the trainer holds it.

[0052] The present invention designs the handpiece 2 to be a hollow structure, and provides an insert column 21 and a limit block 22 at both ends of the handpiece 2, and provides an insert hole 121 and a limit groove 122 correspondingly on the cavity wall of the assembly cavity 12, so that after the two ends of the handpiece 2 are assembled with the inner support body 1, the insert column 21 can be used to cooperate with the insert hole 121 and the limit block 22 to cooperate with the limit groove 122 to effectively limit the handpiece 2, and the elastic foam filling material can enter the interior of the handpiece 2 for foaming molding, thereby effectively improving the connection strength between the handpiece 2 and the inner support body 1, ensuring that the handpiece 2 will not separate from the inner support body 1 during use.

[0053] In the present invention, the lower edge of the inner support body 1 extends outward to form an extension portion 13. The edge of the extension portion 13 is sealed and connected to the elastic surface layer 3. Specifically, the edge of the extension portion 13 is directly and fixedly sealed and connected to the elastic surface layer 3 during rotational molding; the pouring opening 11 is provided on the extension portion 13. By forming the extension portion 13 at the lower edge of the inner support body 1 and sealing the edge of the extension portion 13 to the elastic surface layer 3 during rotational molding, the present invention can better form a accommodating space between the inner support body 1 and the elastic surface layer 3. In this way, the elastic foam layer 4 and the elastic surface layer 3 are combined to have greater elasticity, which can further enhance the striking feel.

[0054] In the present invention, the inner support body 1 is integrally formed by injection molding using an injection mold to ensure the strength of the entire inner support body 1, ensuring that it is not easily damaged during use, and at the same time, the inner support body 1 is more convenient to manufacture. The handpiece 2 is integrally formed by blow molding using a blow mold to ensure the strength of the entire handpiece 2, ensuring that it is not easily damaged during use, and at the same time, the handpiece 2 is more convenient to manufacture.

[0055] The present invention further provides a method for producing a boxing target 100. The specific structure of the boxing target 100 is described in detail above. The production method comprises the following steps:

[0056] Step S1: prefabricate an inner support body 1 and a handpiece 2. The inner support body 1 is provided with a pouring opening 11 to facilitate pouring of elastic foam filler through the pouring opening 11. The inner support body 1 is integrally formed by injection molding using an injection mold; the handpiece 2 is integrally formed by blow molding using a blow molding mold, so that the handpiece 2 has a hollow structure.

[0057] Step S2: placing the inner support body 1 into a rotational molding mold, adding material components into the rotational molding mold, and forming an elastic surface layer 3 on the outside of the inner support body 1 through a rotational molding process, so that a filling chamber 5 is formed between the inner support body 1 and the elastic surface layer 3, and the filling chamber 5 is connected to the pouring opening 11, so that the elastic foam filling material can be poured into the filling chamber 5 through the pouring opening 11;

[0058] Step S3 , installing the handpiece 2 on the inner support body 1 , pouring the elastic foam filler into the filling chamber 5 through the pouring opening 11 , so that the elastic foam filler is foamed and formed in the filling chamber 5 to form an elastic foam layer 4 .

[0059] In the present invention, in order to better realize the molding of the elastic surface layer 3 on the outside of the inner support body 1, in the rotational molding process, the molding temperature of the rotational molding mold is 260°C-390°C, and the rotation speed of the rotational molding mold is 1400-1600 revolutions per hour.

[0060] In the present invention, to produce an elastic surface layer 3 that more closely resembles the structure of human skin, in step S2, the material components, by weight, are as follows: 2-3 parts heat-resistant agent, 4-5 parts stabilizer, 2-4 parts softener, 65-75 parts oil, and 75-85 parts polyvinyl chloride paste resin. The heat-resistant agent is R39, the stabilizer is 1934, the softener is 2050, the oil is dibutyl oil, and the polyvinyl chloride paste resin is a dispersion of a paste of PVC powder in a non-volatile plasticizer. The heat-resistant agent improves the material's heat resistance, ensuring that the elastic surface layer 3 can bond to the edge of the extension 13 during rotational molding. The stabilizer enhances the material's stability. The softener softens the material, ensuring that the resulting elastic foam layer 4 is highly elastic.

[0061] In the present invention, in order to ensure that the handpiece 2 and the inner support body 1 can be reliably combined together, an assembly cavity 12 with an opening facing downward is formed in the inner support body 1, and the handpiece 2 is a hollow structure; limit blocks 22 are provided at both ends of the handpiece 2, and the free end surface of each limit block 22 is provided with a plug-in column 21, and the free end of each plug-in column 21 is provided with a connecting opening 211 connected to the filling chamber 5, so that the elastic foam filling material can enter the handpiece 2 through the connecting opening 211; the cavity wall of the assembly cavity 12 is provided with a plug-in hole that cooperates with the plug-in column 21 121 and a limiting groove 122 cooperating with the limiting block 22; in step S3, the handpiece 2 is installed on the inner support body 1 specifically as follows: the plug-in columns 21 at both ends of the handpiece 2 are inserted into the plug-in holes 121 of the cavity wall of the assembly cavity 12, and the limiting block 22 of the handpiece 2 is clamped in the limiting groove 122 of the cavity wall of the assembly cavity 12; at the same time, when the elastic foam filler is poured into the filling chamber 5 through the pouring opening 11, the elastic foam filler can enter the interior of the handpiece 2, so that the interior of the handpiece 2 and the filling chamber 5 can form an elastic foam layer 4 connected as one.

[0062] The technical solution of the present invention is further described below with reference to some specific embodiments: Example

[0072] Step S3, insert the plug-in columns 21 at both ends of the handpiece 2 into the plug-in holes 121 of the cavity wall of the assembly cavity 12, and make the limit blocks 22 of the handpiece 2 be clamped in the limit grooves 122 of the cavity wall of the assembly cavity 12; pour the elastic foam filler into the filling cavity 5 through the pouring opening 11, so that the elastic foam filler is foamed and formed in the filling cavity 5 and the handpiece 2 to form an elastic foam layer 4.
