Description

An improved swimming device

Technical field

The utility model relates to the field of swimming devices, in particular to an improved swimming device.

Background technique

At present, the swimming device used by swimmers is mainly a swimming ring. The swimming ring generally has a circular structure and the surrounding volume is basically the same. When the swimmer uses the swimming ring for swimming, the human body is basically leaning forward or backward. At this time, the force of the swimming ring is mainly concentrated on the front end or the rear end. Due to the structural design limitations of the existing swimming ring, there will be insufficient buoyancy at the front or rear end, resulting in the problem of unbalanced buoyancy of the entire swimming ring. It is easy to cause the swimmer to lean forward too much or even cause the head to fall into the water. The use of this type of swimming ring has greater hidden dangers. Moreover, in order to increase the buoyancy of the existing swimming ring, the volume of the ring part of the body of the swimming ring is often increased. This method will cause the swimmer to have a greater interference with the arm during wearing and use, and reduce the comfort of use.

Detailed ways

Example one:

As shown in Figure 1, the utility model provides an improved swimming device, including a device body (1). The device body (1) can be made by bonding several pieces of PVC film using a high-frequency processing technology, and an air cavity is formed inside, and an inflating nozzle for pumping air into the air cavity is provided on the surface of the device body. In addition, the device body (1) can also be made of solid materials. Specifically, the solid materials can be one or more of lightweight materials such as EPE, EPS, EVA, NBR, SBR, TPE, SEBS, or EPDM. .

The device body (1) has a flat structure as a whole. In addition, those of ordinary skill in the art can also make the body (1) of the swimming ring take other shapes and forms, such as the upper and lower surfaces being curved, which also belong to the protection scope of the present invention.

As shown in Figure 2, through the structural design, an accommodating through hole (2) is provided in the middle of the device body (1). The accommodating through hole (2) penetrates the upper and lower surfaces of the device body (1) to accommodate The hole shape of the through hole (2) is an oval shape, and the containing through hole (2) is closed, that is, the edges of the containing through hole (2) are all located in the device body (1). On the top view of the device body (1), the geometric center point A of the oval-shaped receiving through hole (2) is taken as the base point, and there is an X centerline in the vertical direction through the base point A. The device body (1) The outer contour is symmetrical with the X centerline as the axis. The outer edges of the left and right sides of the device body (1) are provided with inner recesses (3) in the direction of the receiving through hole (2), and the contour of the inner recess (3) is arc-shaped, so that the edges of the inner recess (3) and the receiving The edge distance of the through hole (2) is small.
