Description

Hanging boxing bag and manufacturing method Technical Field

[0001] The present invention relates to the technical field of boxing bags, in particular to a hanging boxing bag and a manufacturing method thereof. Background Art

[0002] A punching bag is a piece of fitness equipment that allows users to perform exercises by simply hanging it and hitting it. Traditional punching bags are filled with sand or rags. Sand-filled bags are bulky, difficult to transport, and offer a poor punching experience, so they are gradually being phased out. Bags filled with rags are loose and easily dented or deformed after being hit, resulting in a poor punching experience and inconvenient transportation.

[0003] Of course, to facilitate the transportation of punching bags, water-filled and air-inflated punching bags exist in the prior art. For example, Chinese Utility Model Patent Application No. 202320011971.0 discloses a water-filled and air-inflated punching bag. The bag comprises a hollow body with an air inlet mechanism and a water inlet hole at the top, the air inlet mechanism being located to one side of the water inlet hole. A base is provided at the bottom of the body, the base containing a sponge layer. A zipper is provided between the base and the body, and the base and the body are movably connected by the zipper. This punching bag has a simple structure, is easy to carry, and can be adjusted to meet user needs to meet usage requirements. However, after water is filled and inflated, the water concentrates in the lower portion of the bag, resulting in uneven weight throughout the bag, making it prone to swaying during punching and providing a poor feel. In view of the above-mentioned problems, the inventors of this case conducted in-depth research on this issue, which led to the present invention. Technical issues

[0004] The technical problem to be solved by the present invention is to provide a hanging boxing bag and a manufacturing method to solve the problems of uneven weight of existing boxing bags, easy swaying during hitting, and poor hitting feel. Technical Solutions

[0005] The present invention is achieved in that:

[0006] In a first aspect, a hanging boxing bag comprises an inner bag body and an outer bag body, wherein the outer bag body is sleeved on the outside of the inner bag body; a first closed chamber is formed inside the inner bag body, a second closed chamber is formed between the outer wall of the inner bag body and the inner wall of the outer bag body, and a water injection and air inflation port is fixedly provided on the inner bag body; the second closed chamber is filled with a water-absorbing elastic layer, and the outer bag body is fixedly provided with a water injection port.

[0007] Furthermore, the water-absorbing elastic layer is a water-absorbing sponge layer.

[0008] Furthermore, the connection points of the inner bag body, the connection points of the outer bag body, and the connection points between the inner bag body and the outer bag body are all sealed and welded together by hot melting.

[0009] Furthermore, the water-absorbing elastic layer is obtained by foaming a foaming raw material poured into the second closed chamber, and the thickness of the water-absorbing elastic layer is 2-4 cm.

[0010] Furthermore, the inner bag body and the outer bag body are both made of wear-resistant and waterproof fabrics.

[0011] Furthermore, the water filling and air inflation port is located at the upper end or lower end of the inner bag body, and the water filling port is located at the upper end or lower end of the outer bag body.

[0012] Furthermore, an air-inflating port is fixedly provided on the outer bag body, and the air-inflating port is located at the upper end or the lower end of the outer bag body.

[0013] Furthermore, a sling or a sling is fixedly provided at the upper end of the outer bag body.

[0014] In a second aspect, a method for manufacturing a hanging boxing bag comprises the following steps:

[0015] Use wear-resistant and waterproof fabrics to weld the inner bag body and the outer bag body by hot melting, put the outer bag body on the outside of the inner bag body, and weld the two ends of the outer bag body to the two ends of the inner bag body by hot melting to seal them together;

[0016] A first assembly opening is provided at the end of the inner bag body, a water injection and air filling opening is installed on the first assembly opening, and the edge of the first assembly opening is welded and sealed to the water injection and air filling opening by hot melting; a second assembly opening and a third assembly opening are provided at the end of the outer bag body, a water injection opening is installed on the second assembly opening, and the edge of the second assembly opening and the water injection opening are welded and sealed to each other by hot melting; an air pump opening is installed on the third assembly opening, and the edge of the third assembly opening and the air pump opening are welded and sealed to each other by hot melting;

[0017] Inflate the first closed chamber through the water injection port to expand the inner bag body; inflate the second closed chamber through the air pumping port to expand the outer bag body; and at the same time, pour foaming raw materials into the second closed chamber through the water injection port to foam the foaming raw materials into a water-absorbing elastic layer in the second closed chamber. After foaming is completed, the gas in the first closed chamber is discharged.

[0018] Furthermore, the foaming raw material includes black material and white material, and the ratio of the black material to the white material is 100:50. Beneficial effects

[0019] By adopting the technical solution of the present invention, at least the following beneficial effects are achieved:

[0020] 1. The hanging boxing bag is designed to have a double-layer structure with an inner bag body and an outer bag body, and a water-absorbing elastic layer is filled in a second closed chamber between the inner bag body and the outer bag body. A water injection port is fixedly provided on the outer bag body, so that when in use, water can be injected into the second closed chamber through the water injection port. The injected water can be absorbed by the water-absorbing elastic layer and distributed throughout the entire water-absorbing elastic layer from top to bottom. Therefore, the weight distribution of each position of the hanging boxing bag is more uniform, and there is no swaying during the hitting process, which provides a better user experience. At the same time, the water-absorbing elastic layer has a muscle feel after absorbing water, so that the hitter has a feeling of hitting the muscle when hitting the hanging boxing bag, and the hitting feel is good.

[0021] 2. The water-absorbing elastic layer has good elasticity. The concave part after being hit can quickly return to its original shape under the action of elastic force. Therefore, compared with the boxing bag filled with rags, it can effectively avoid the concave and deformed situation after being hit. At the same time, the water-absorbing elastic layer is not easily damaged, which helps to extend the service life of the entire hanging boxing bag.

[0022] 3. Since the inflation and water injection of the hanging boxing bag can be operated by the user, there is no need to inflate or inject water into the hanging boxing bag before it reaches the user. The entire hanging boxing bag is relatively small in size and light in weight, and is very convenient to transport.

[0023] 4. Because the striker hits the surface of the outer bag during training, even if the outer bag is damaged during use, the water in the second closed chamber will only drip down slowly under the adsorption of the water-absorbing elastic layer, and will not directly spill onto the ground, and will not affect continued use.

[0024] 5. The joints of the inner bag body, the outer bag body, and the inner bag body and the outer bag body are welded together by hot melting, which can ensure the sealing of the entire hanging boxing bag, ensure that the water filled in the hanging boxing bag will not seep out, evaporate, and ensure that the gas filled in the hanging boxing bag will not escape.

[0025] 6. By pouring foaming raw materials into the second closed chamber to perform foaming molding to obtain the water-absorbing elastic layer, the water-absorbing elastic layer can better fill the space in the entire second closed chamber. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] 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.

[0040] 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 positions or relationships, are based on the positions or 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. Example

[0041] 1 and 2 , a preferred embodiment of a hanging punching bag 100 of the present invention is shown. The hanging punching bag 100 includes an inner bag body 1 and an outer bag body 2. The outer bag body 2 is sleeved on the outside of the inner bag body 1. That is, the entire hanging punching bag 100 has a double-layer structure including the inner bag body 1 and the outer bag body 2. The interior of the inner bag body 1 forms a first closed chamber 11, and the outer wall of the inner bag body 1 and the inner wall of the outer bag body 2 form a second closed chamber 21. The inner bag body 1 is fixedly provided with a water injection and inflation port 3. When the hanging boxing bag 100 is in use, water and / or air can be injected into the first closed chamber 11 through the water injection and inflation port 3; the second closed chamber 21 is filled with a water-absorbing elastic layer 4, and the outer bag body 2 is fixedly provided with a water injection port 5. When the hanging boxing bag 100 is in use, water can be injected into the second closed chamber 21 through the water injection port 5, and the water injected into the second closed chamber 21 can be absorbed by the water-absorbing elastic layer 4.

[0042] By adopting the above technical solution of the present invention, at least the following beneficial effects are achieved:

[0043] 1. The hanging punching bag 100 is designed to have a double-layer structure comprising an inner bag body 1 and an outer bag body 2. A water-absorbing elastic layer 4 is filled in a second closed chamber 21 between the inner bag body 1 and the outer bag body 2. A water inlet 5 is fixedly provided on the outer bag body 2. When in use, water can be injected into the second closed chamber 21 through the water inlet 5. The injected water can be absorbed by the water-absorbing elastic layer 4 and distributed throughout the entire water-absorbing elastic layer 4 from top to bottom. Therefore, the weight distribution of the hanging punching bag 100 is more uniform at all positions, and the bag will not sway during the punching process, providing a better user experience. At the same time, the water-absorbing elastic layer 4 has a muscular feel after absorbing water, so that the puncher feels as if they are hitting their muscles when hitting the hanging punching bag 100, and the punching feel is good.

[0044] 2. The water-absorbing elastic layer 4 has good elasticity. The concave portion after being hit can quickly return to its original shape under the action of elastic force. Therefore, compared with a boxing bag filled with rags, it can effectively avoid dents and deformation after being hit. At the same time, the water-absorbing elastic layer 4 is not easily damaged, which helps to extend the service life of the entire hanging boxing bag 100.

[0045] 3. Since the inflation and water injection of the hanging punching bag 100 can be operated by the user, there is no need to inflate or inject water into the hanging punching bag 100 before it reaches the user. The entire hanging punching bag 100 is relatively small in size and light in weight, and is very convenient to transport.

[0046] 4. Because the striker hits the surface of the outer bag 2 during training, even if the outer bag 2 is damaged during use, the water in the second closed chamber 21 will only drip down slowly under the adsorption of the water-absorbing elastic layer 4, and will not directly spill onto the ground, and will not affect continued use.

[0047] As a specific embodiment of the present invention, in order to enable the water-absorbing elastic layer 4 to absorb water better, the water-absorbing elastic layer 4 is a water-absorbing sponge layer.

[0048] In a preferred embodiment of the present invention, the connections of the inner bag 1, the outer bag 2, and the connection between the inner bag 1 and the outer bag 2 are all sealed together by heat-melting. By heat-melting the connections of the inner bag 1, the outer bag 2, and the connection between the inner bag 1 and the outer bag 2, the present invention ensures the sealing of the entire hanging punching bag 100, ensuring that water filled in the hanging punching bag 100 does not seep out or evaporate, and that gas filled in the hanging punching bag 100 does not escape.

[0049] In a preferred embodiment of the present invention, the water-absorbing elastic layer 4 is formed by foaming a foaming material poured into the second enclosed chamber 21. By foaming the water-absorbing elastic layer 4 by pouring the foaming material into the second enclosed chamber 21, the water-absorbing elastic layer 4 can better fill the entire space within the second enclosed chamber 21.

[0050] In a preferred embodiment of the present invention, the water-absorbing elastic layer 4 has a thickness of 2-4 cm. If the water-absorbing elastic layer 4 is too thin, it will not absorb enough water to achieve the desired weight. If the water-absorbing elastic layer 4 is too thick, the entire hanging punching bag 100 will be too large and heavy, making it inconvenient to hang, and also increasing manufacturing costs. Therefore, the present invention designs the water-absorbing elastic layer 4 to have a thickness of 2-4 cm. This ensures that the water-absorbing elastic layer 4 can absorb enough water to achieve the desired weight, facilitates the hanging operation of the hanging punching bag 100, and reduces manufacturing costs. Preferably, the water-absorbing elastic layer 4 has a thickness of 3 cm.

[0051] In a preferred embodiment of the present invention, since the hanging punching bag 100 needs to be filled with water and inflated, high waterproof and wear-resistant properties are required. Therefore, the inner bag body 1 and the outer bag body 2 are both made of wear-resistant and waterproof fabric. In a specific implementation of the present invention, the inner bag body 1 and the outer bag body 2 can both be made of fabric used in rubber boats and assault boats, such as Hypalon fabric, PVC fabric, or polyurethane fabric.

[0052] In a preferred embodiment of the present invention, the water injection and air inlet 3 is located at the upper or lower end of the inner bag body 1, and the water inlet 5 is located at the upper or lower end of the outer bag body 2. By locating both the water injection and air inlet 3 and the water inlet 5 at the end positions, any impact on the user's strikes can be avoided. Preferably, the water injection and air inlet 3 is located at the upper end of the inner bag body 1, and the water inlet 5 is located at the upper end of the outer bag body 2.

[0053] In a preferred embodiment of the present invention, the outer bag body 2 is further provided with an air inlet 6, which is located at the upper end or the lower end of the outer bag body 2. Since foaming material needs to be poured between the inner bag body 1 and the outer bag body 2 for foaming during manufacturing, the air inlet 6 is provided on the outer bag body 2 to facilitate the inflating of the second closed chamber 21 through the air inlet 6, so that the entire outer bag body 2 is in an expanded state, thereby making it easier to pour the foaming material into the second closed chamber 21.

[0054] It should be noted that the water injection and inflation port 3, the water injection port 5 and the air pumping port 6 are all frequently used in the prior art and have also been widely used in boxing bags. Their specific structures are well known to those skilled in the art, so the specific structures of the water injection and inflation port 3, the water injection port 5 and the air pumping port 6 will not be introduced in detail here; in addition, in order to further improve the sealing effect, the water injection and inflation port 3, the water injection port 5 and the air pumping port 6 can be equipped with a sealing cover 7.

[0055] In a preferred embodiment of the present invention, a sling or a sling 8 is fixedly provided at the upper end of the outer bag body 2 to facilitate hanging the hanging boxing bag 100.

[0056] When the hanging boxing bag 100 of the present invention is used, the user can inject water and / or inflate the first closed chamber 11 through the water injection and inflation port 3 according to the softness and hardness requirements. That is, the first closed chamber 11 can be filled with water, or the first closed chamber 11 can be filled with air, or the first closed chamber 11 can be first injected with water and then inflated with air. The specific selection can be made according to actual needs, and the amount of water injected and the amount of air injected can also be selected according to actual needs; at the same time, water can be injected into the second closed chamber 21 through the water injection port 5, and the specific amount of water injected can also be selected according to actual needs, so that the water-absorbing elastic layer 4 can absorb water to increase weight and have a muscular feel, and the water can be evenly distributed to various positions of the water-absorbing elastic layer 4, so that the weight of the entire hanging boxing bag 100 at various positions is more uniform, thereby improving the hitting experience and hitting feel. Example

[0057] 1 and 2 , a preferred embodiment of a method for manufacturing a hanging punching bag 100 of the present invention is shown. The specific structure of the hanging punching bag 100 is described in detail in Example 1 and will not be further described here. The manufacturing method comprises the following steps:

[0058] Step S1: Use wear-resistant and waterproof fabrics to weld the inner bag body 1 and the outer bag body 2 by hot-melt method, put the outer bag body 2 on the outside of the inner bag body 1, and weld the two ends of the outer bag body 2 to the two ends of the inner bag body 1 by hot-melt method. When implementing this step S1, the following two specific implementation methods are included:

[0059] The first specific implementation method: use wear-resistant and waterproof fabrics to weld by hot melt to form a completely closed inner bag body 1, use wear-resistant and waterproof fabrics to weld by hot melt to form an outer bag body 2 with open ends, put the outer bag body 2 on the outside of the inner bag body 1, and weld the two ends of the outer bag body 2 to the two ends of the inner bag body 1 by hot melt to seal them together.

[0060] In the second embodiment, an inner bag body 1 with open ends is formed by hot-melt welding using wear-resistant and waterproof fabrics, and an outer bag body 2 with open ends is formed by hot-melt welding using wear-resistant and waterproof fabrics. The outer bag body 2 is sleeved on the outside of the inner bag body 1, and both ends of the inner bag body 1 and the outer bag body 2 are welded and sealed together using wear-resistant and waterproof fabrics.

[0061] Step S2: A first assembly port 12 is formed at the end of the inner bag body 1, and a water injection and air filling port 3 is installed on the first assembly port 12. The edge of the first assembly port 12 is welded and sealed to the water injection and air filling port 3 by hot melting to ensure a sealing effect; a second assembly port 22 and a third assembly port 23 are formed at the end of the outer bag body 2, and a water injection port 5 is installed on the second assembly port 22. The edge of the second assembly port 22 is welded and sealed to the water injection port 5 by hot melting to ensure a sealing effect; an air pumping port 6 is installed on the third assembly port 23, and the edge of the third assembly port 23 is welded and sealed to the air pumping port 6 by hot melting to ensure a sealing effect;

[0062] Step S3, inflate the first closed chamber 11 through the water filling port 3 to expand the inner bag body 1, so as to ensure that the thickness of the water-absorbing elastic layer 4 after molding is more uniform; inflate the second closed chamber 21 through the inflation port 6 to expand the outer bag body 2, and at the same time, pour the foaming raw material into the second closed chamber 21 through the water filling port 5, so that the foaming raw material is foamed and molded into the water-absorbing elastic layer 4 in the second closed chamber 21. After foaming is completed, the gas in the first closed chamber 11 is discharged, thereby facilitating the packaging and transportation of the hanging boxing bag 100. During the specific implementation of the present invention, during the process of pouring the foaming raw material into the second closed chamber 21 through the water injection port 5, the second closed chamber 21 needs to be continuously and slowly inflated through the air pumping port 6. At the same time, a portion of the gas in the second closed chamber 21 can escape out through the water injection port 5, so that the outer bag body 2 can remain in an expanded and stretched state; in addition, when the can material is about to be completed, stop pumping air into the second closed chamber 21 and keep the water injection port 5 open, so that the gas generated by the foaming raw material during the foaming molding process can be discharged out through the water injection port 5.

[0063] In a preferred embodiment of the present invention, the foaming raw materials include black material and white material, with the ratio of black material to white material being 100:50. The black material is used to control hardness, and the white material is used to control softness. By adopting this ratio, the water-absorbing elastic layer 4 after foaming is neither too hard nor too soft, and the water-absorbing elastic layer 4 has a firm feeling like muscle after absorbing water, thereby improving the striking feel. In the specific implementation of the present invention, the black material and the white material need to be mixed according to the ratio and then poured into the second closed chamber 21, so that the foaming raw materials are foamed and formed into the water-absorbing elastic layer 4 in the second closed chamber 21. It should be noted that the black material and the white material are very common materials in the prior art. The black material is composed of polyisocyanate, and the white material is composed of polyether polyol or polyester polyol, a blowing agent, a catalyst, a surfactant, etc. Because the black material and the white material are well-known materials in the prior art, they will not be described in detail here.

[0064] Although the specific embodiments of the present invention are described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included within the scope of protection of the claims of the present invention.
