Problems solved by technology

[0007] The purpose of the present invention is: in order to solve the problem that all the hinges in the existing swimming accelerator are completely on the same plane when they are unfolded, and cannot be opened and closed quickly. When the legs are retracted, the pedal and the water have a certain contact area. The effective contact area is small and cannot be closed quickly. The opening and closing process does not conform to fluid mechanics, which is not conducive to speeding up, and the technical problem of accelerating the human body is not fast enough. The invention provides an auxiliary accelerator for swimming with increased power.

Embodiment 1

[0037] Such as Figures 1 to 7 As shown, this embodiment provides a power-increasing swimming auxiliary accelerator, which includes a kit 1, and a plurality of sets of hinge shafts 2 arranged obliquely outward are connected to the kit 1 along the circumference of the kit 1, and each group of hinge shafts 2 is horizontal to the kit 1. The included angle of the end faces is an acute angle, and each set of hinge shafts 2 is provided with a pair of hinges 3 that can rotate around the axes of the hinge shafts 2 .

[0038] In this embodiment, the kit worn on the calf of the human body is used to replace the traditional pedals worn on the feet. At the same time, a plurality of sets of hinge shafts arranged obliquely outward are arranged on the outer edge of the kit, and each set of hinge shafts is hinged with a For the hinge, because the angle between the hinge shaft and the horizontal end surface of the kit is an acute angle, when the hinge is fully unfolded under the action of wate...

Embodiment 2

[0040] Such as Figures 1 to 7 As shown, this embodiment is further optimized on the basis of embodiment 1. Specifically, the hinge shafts 2 are evenly distributed on the outer edge of the kit 1, and there are several brackets arranged alternately with the hinge shafts 2 in the peripheral direction of the kit 1. 4. The included angle between the bracket 4 and the horizontal end face of the kit 1 is equal to the angle between the hinge shaft 2 and the horizontal end face of the kit 1, the angle between the hinge shaft 2 and the horizontal end face of the kit 1 is 30°-60°, and the bracket 4 is provided with at least A limit block A5 for preventing the hinge 3 from opening beyond 180°, and at least one limit block B6 for preventing the hinge 3 from being completely closed is provided on the hinge shaft 2 .

[0041] In this embodiment, when the hinge is unfolded, the hinge is prevented from continuing to rotate under the action of the limit block A, so that the maximum angle of ea...

Embodiment 3

[0043] Such as Figures 1 to 4 As shown, this embodiment is further optimized on the basis of Embodiment 2. Specifically, the kit 1 is provided with a coupling device for fixing the kit 1 on the lower leg of the human body. The coupling device includes a connecting frame A7 and a connecting frame B8. , shrinkage band A9, shrinkage band B10 and U-shaped sheath 11, connecting frame A7 and connecting frame B8 are respectively arranged at the upper and lower ends of the suite 1, the shrinking band A9 is connected to the top of the suite 1 through several connecting frames A7, and the shrinking band B10 is connected through several connections The frame B8 is connected under the kit 1, and the U-shaped sheath 11 is connected to the inner side of the kit 1 through several struts 15, and the inner opening of the kit 1 is a regular hexagon.

[0044] In this embodiment, when wearing, first put the foot through the kit so that the kit is located on the lower leg of the human body, the U...

Abstract

The invention discloses a power augmentation swimming assistant accelerator, and relates to the technical field of fitness appliances. The power augmentation swimming assistant accelerator comprises acasing piece, a plurality of sets of hinge shaft which incline outwards are connected to the casing piece in the circumferential direction, the included angle of each set of hinge shaft and the horizontal end face of the casing piece is an acute angle, and each set of hinge shaft is sleeved with a pair of hinges which can rotate around the axis of the hinge shaft. The power augmentation swimmingassistant accelerator has the advantages that the structure is simple, the opening and closing speed of the hinges is high, and swimming can be accelerated rapidly.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, and more specifically relates to a power-increasing swimming auxiliary accelerator. Background technique [0002] Swimming is a skill in which people float upward under the buoyancy of water, and rely on buoyancy to move their limbs regularly to make the body move regularly in the water. Swimming is one of the favorite sports for men, women and children. Ancient swimming, according to the research of existing historical materials, has a more consistent view at home and abroad that it originated from the ancient people who lived in rivers, rivers, lakes and seas. , It is necessary to catch water birds and fish in the water for food, and gradually learn to swim by observing and imitating the movements of fish, frogs and other animals swimming in the water. Swimming, as one of the current popular fitness items, is more and more popular among young people. Swimming fitness can improve the ...
