Description

Technical Field

[0001] This utility model belongs to the field of swimming auxiliary equipment, and in particular relates to a drag-type swimming resistance training device. Background Technology

[0002] Currently, drag-type swimming resistance training equipment tends to sway underwater when dragged, and the swaying range is large. This affects the swimmer's posture and training effect. For example, the training pack disclosed in document CN206152227U "Swimming Resistance Training Pack" involves attaching a belt to the waist and dragging the resistance bag through a connecting rope for resistance training. However, the resistance bag has a low density, making it relatively light and unstable. It cannot adjust the buoyancy of the device and has no water flow guidance. When dragged underwater, the swaying is obvious, which seriously affects the stability of the magnitude and direction of the resistance applied, and the resistance training effect cannot be guaranteed. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a towed swimming resistance training device with a simple structure and good underwater stability.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A drag-type swimming resistance training device includes a central cylinder, a drag rope, a waist belt, and multiple resistance bags. The central cylinder is arranged in a front-to-back direction, and the multiple resistance bags are arranged in a front-to-back direction on the outer wall of the central cylinder and are distributed circumferentially on the outer wall of the central cylinder. One end of the drag rope is connected to the front end of the central cylinder, and the other end of the drag rope is connected to the waist belt.

[0005] The beneficial effects of the above technical solution are as follows: multiple impedance bags are distributed circumferentially with the central cylinder as the carrier, and the towing rope is connected to the front end of the central cylinder. At this time, the waist belt is tied around the swimmer's waist, and the towing rope pulls the underwater central cylinder forward at an angle downward. At this time, multiple impedance bags apply backward resistance evenly to provide the swimmer with stable swimming resistance, thereby increasing the training intensity.

[0006] The impedance bag described in the above technical solution is trumpet-shaped, with both ends open, and its thicker end facing forward and connected to the central cylinder.

[0007] The beneficial effect of the above technical solution is that the water flow through the impedance bag exerts a backward force on the impedance bag, but the water flow inside the impedance bag also improves the stability of the impedance bag and avoids large shaking of the impedance bag.

[0008] In the above technical solution, a first rigid ring is provided at the front end of the central cylinder, and a second rigid ring is provided at the thick end of the impedance bag. The first rigid ring and a plurality of second rigid rings are coplanar, and each second rigid ring is connected to the first rigid ring.

[0009] The beneficial effect of the above technical solution is that it allows the front end of the central cylinder and the impedance bag to always remain open, which facilitates the flow of water.

[0010] In the above technical solution, the end of the tow rope away from the waist belt is provided with multiple sub-tow ropes. The ends of the multiple sub-tow ropes are connected to the first rigid ring, and the connection points of the multiple sub-tow ropes to the first rigid ring are evenly distributed around the first rigid ring in a circumferential direction.

[0011] The beneficial effect of the above technical solution is that it allows the towing rope to be connected to the front end of the central cylinder at multiple points through multiple sub-ropes, thereby improving the stability of the central cylinder and the impedance bag underwater.

[0012] The central cylinder described in the above technical solution has an annular cavity inside its wall, and a filling port communicating with the annular cavity is provided on the central cylinder. The filling port is provided with a cover, and the annular cavity is used to add liquid and / or gas to adjust the buoyancy of the central cylinder.

[0013] The beneficial effect of the above technical solution is that the overall density of the central cylinder can be adjusted by adding liquid and / or gas into the annular cavity, so that the tow body composed of the central cylinder and multiple impedance bags can be close to the water surface or submerged underwater as needed.

[0014] The materials of the central cylinder and the impedance bag mentioned in the above technical solution are both waterproof fabrics.

[0015] The beneficial effect of the above technical solution is that it allows the entire drag swimming resistance training device to dry quickly after use.

[0016] In the above technical solution, multiple impedance bags are connected to each other on the side of the central cylinder that is close to each other.

[0017] The beneficial effect of the above technical solution is that it can prevent the rear end of the impedance bag from shaking under the action of water flow, thus preventing the entire towing body from shaking.

[0018] The rear end of the central cylinder in the above technical solution is provided with a third rigid ring.

[0019] The beneficial effect of the above technical solution is that the rear end of the central cylinder can also remain open, which reduces the resistance when water flows through the central cylinder, thereby maintaining the stability of the towing body.

[0020] The central cylinder described in the above technical solution is further provided with multiple support columns, and the two ends of each support column are respectively connected to the first rigid ring and the third rigid ring.

[0021] The beneficial effect of the above technical solution is that it allows the central cylinder to remain straight under the support of multiple support columns, thus making the central cylinder more stable and reducing the amplitude of swaying under the action of water flow.

[0022] The belt described in the above technical solution includes a belt body and a connector. The belt body is a flat belt, and the two ends of the belt body are connected by the connector to be worn on the waist. The corresponding end of the towing rope is connected to the belt body or the connector.

[0023] The advantages of the above technical solution are that it has a simple structure and is more convenient to wear around the waist. Attached Figure Description

[0031] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0032] like Figure 1 As shown, this embodiment provides a drag-type swimming resistance training device, including a central cylinder 1, a drag rope 2, a waist belt 3, and multiple resistance bags 4. The central cylinder 1 is arranged in a front-to-back direction, and the multiple resistance bags 4 are arranged in a front-to-back direction on the outer wall of the central cylinder 1, and are distributed circumferentially at intervals on the outer wall of the central cylinder 1. One end of the drag rope 2 is connected to the front end of the central cylinder 1, and the other end of the drag rope 2 is connected to the waist belt 3. In this way, the multiple resistance bags are carried by the central cylinder and are distributed circumferentially at intervals, while the drag rope is connected to the front end of the central cylinder. At this time, the waist belt is tied around the waist of the swimmer, and the drag rope pulls the underwater central cylinder forward at an angle downward. At this time, the multiple resistance bags apply a uniform backward resistance to provide the swimmer with stable swimming resistance, thereby increasing the training intensity.

[0033] The central cylinder and multiple impedance bags can be combined to form a towed vehicle.

[0034] like Figure 1 and Figure 2 As shown, the impedance bag 4 in the above technical solution is trumpet-shaped, with both ends open and its thicker end facing forward and connected to the central cylinder 1. This allows the water flow to exert a backward force on the impedance bag as it flows through it, while the water flow inside the impedance bag also improves the stability of the impedance bag and prevents it from shaking.

[0035] The length of the central tube can be 30-50cm, and the length of the impedance bag is similar to that of the central tube. The central tube is a cylinder with an inner diameter of about 20cm. The inner diameter of the thick end of the impedance bag can be about 10cm, and the inner diameter of the thin end can be about 5cm.

[0036] like Figure 3 As shown, in the above technical solution, the front end of the central cylinder 1 is provided with a first rigid ring 11, and the thick end of the impedance bag 4 is provided with a second rigid ring 41. The first rigid ring 11 and multiple second rigid rings 41 are coplanar, and each second rigid ring 41 is connected to the first rigid ring 11. This allows the front ends of the central cylinder and the impedance bag to always remain open, which facilitates water flow.

[0037] like Figure 1 As shown in the above technical solution, the towing rope 2, at the end furthest from the waist belt 3, is provided with multiple sub-ropes 21. The ends of the multiple sub-ropes 21 are connected to the first rigid ring 11, and the connection points of the multiple sub-ropes 21 to the first rigid ring 11 are evenly distributed around the first rigid ring 11 in a circumferential direction. This allows the towing rope to be connected to the front end of the central cylinder at multiple points through multiple sub-ropes, thereby improving the stability of the central cylinder and the impedance bag underwater. In this embodiment, at least three sub-ropes are provided.

[0038] like Figure 5 As shown, in the above technical solution, the inner wall of the central cylinder 1 has an annular cavity 12. The central cylinder 1 has a filling port 121 communicating with the inner wall of the annular cavity 12. The filling port 121 has a cover 122. The annular cavity 12 is used to add liquid and / or gas to adjust the buoyancy of the central cylinder 1. In this way, by adding liquid and / or gas into the annular cavity, the overall density of the central cylinder can be adjusted [the liquid can be water, the gas can be air, the annular cavity can be completely filled with water (in this case, the towed body is completely submerged in water when towed), or it can be completely filled with air (in this case, the towed body is close to the water surface when towed), or water and air can each occupy a portion (in this case, depending on the ratio of water to air, the towed body may be close to the water surface or submerged in water when towed, depending on the specific situation)]. This allows the towed body composed of the central cylinder and multiple impedance bags to be close to the water surface or submerged in water as needed.

[0039] The central cylinder 1 and the impedance bag 4 described in the above technical solution are both made of waterproof fabric, which allows the entire drag-type swimming resistance training device to dry quickly after use.

[0040] like Figure 2 As shown, in the above technical solution, multiple impedance bags 4 are connected to each other on the side close to the central cylinder 1, which can prevent the rear end of the impedance bag from shaking under the action of water flow and causing the entire towing body to shake.

[0041] like Figure 4 As shown, the rear end of the central cylinder 1 in the above technical solution is provided with a third rigid ring 13, so that the rear end of the central cylinder can also be kept in an open state, which reduces the resistance when the water flows through the central cylinder, thereby maintaining the stability of the towing body; the central cylinder 1 is also provided with multiple support columns 14, and the two ends of each support column 14 are respectively connected to the first rigid ring 11 and the third rigid ring 13, so that the central cylinder can always be kept in a straight state under the support of multiple support columns, which makes the central cylinder more stable under the action of water flow and reduces the swaying amplitude.

[0042] like Figure 6 As shown, the waist belt 3 in the above technical solution includes a belt body 31 and a connector 32. The belt body 31 is a flat belt, and the two ends of the belt body 31 are connected by the connector 32 to be worn on the waist. The corresponding end of the tow rope 2 is connected to the belt body 31 or the connector 32. Its structure is simple and it is more convenient to wear on the waist.

[0043] The belt described in this embodiment can be similar to a trouser belt, and the connector can be a pin buckle or a snap buckle, which are existing technologies and will not be described in detail here.

[0044] In this embodiment, the first, second, and third hard rings can all be wire rings, and the support columns can be steel bars. The support columns are all arranged along the axial direction of the central cylinder, and at least three support columns are provided, with the three support columns evenly distributed circumferentially between the first and third hard rings. In this embodiment, the first, second, and third hard rings and the multiple support columns can be welded into a frame.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
