Embodiment Construction

[0010] In the figure, the push-pull swimming board uses a frame 1 with a handle 4 on the left and right sides of the frame 1; a cavity 7 is arranged in the middle of the frame 1, and a hinge 3 is arranged above the cavity 7, and the other end of the hinge 3 is connected with a blade. 2. The blade 2 can rotate and swing around the hinge 3 relative to the frame 1. When the blade 2 is parallel to the frame 1, the blade 2 closes the corresponding cavity 7. When the blade 2 is perpendicular to the frame 1, the blade 2 is opposite to the cavity 7. It is open, and the area of ​​the open cavity 7 is the largest; the area of ​​the blade 2 is larger than the area of ​​the cavity 7; the number of the blade 2 is greater than or equal to 2. The lower end of each blade 2 is connected together by a synchronous connecting rope 5 . One end of the return elastic 6 is connected to the lower end of the blade 2 , and the other end is connected to the frame 1 . Connecting rope 5 can be made with t...

Abstract

.Provided is a push-pull swimming board. A frame is used, and the left and right sides of the frame are provided with handles; the middle of the frame is a hollow hole, a rotating hinge is arranged above the hollow hole, the other end of the rotating hinge is connected with blades, the blades can rotate and swing around the rotating hinge relative to the frame, when the blades are parallel to theframe, the blades close the corresponding hollow hole, when the blades are perpendicular to the frame, the blades are opened relative to the hollow hole, and the opened hollow hole area is the largest; the blade areas are larger than the area of the hollow hole; the number of the blades is greater than or equal to one. The lower ends of each of the blades are connected together by a synchronous connecting rope. One end of a return rubber string is connected to the lower ends of the blades, and the other end is connected to the frame.

Description

technical field [0001] The invention relates to swimming fins and swimming boards for swimming, especially a "push-pull swimming board", which is a device for accelerating swimming speed and exercising arm strength in water. Background technique [0002] At present, there are relatively few kinds of paddle boards used for arm paddling, and the Chinese patent application number: 99212570.7 "Swimming arm wears a paddle board". A swimming device that is worn on the arm. It is composed of two parts: a clip body and a paddle. The body and the paddle are connected by a hinge, and the paddle can rotate freely within the locking angle. When swimming, the paddle will open and close naturally as the arm moves back and forth, thereby increasing the swimming speed. In addition, since the paddle is set on the forearm, the hands can be freed for other work and games. This patent application has a good idea, but the structure is a bit complicated, and the movement space on the arm is sma...
