Abstract

An automatic open-close diving fin capable of reducing the water resistance and promoting fast advancement comprises a shoe body; a rubber fin surface provided with a strengthening rib is connected to the edge of the sole of the shoe body; an upper limiting plate and a lower limiting plate corresponding to each other are connected to the edge of the sole; the upper limiting plate is positioned above the lower limiting plate; a pin hole is formed on both the upper limiting plate and the lower limiting plate; pins penetrate the pin holes; the strengthening rib penetrates the pins; and a coupling clamp hole is formed at the tail end of the strengthening rib; and the pins penetrate the coupling clamp hole. The diving fin is used for diving for a diver; when the diving fin is worn to dive, the water resistance to the diver is greatly reduced, the propelling effort to water is increased, and the fin surface can be opened and closed freely, so that the consumption of physical strength of the diver is reduced, and the diver can forge ahead quickly.

Description

Automatically opening and closing diving web

Technical field

The utility model relates to a kind of swimming apparatus, relates in particular to a kind of diving of opening and closing automatically web.

Background technology

As everyone knows, in the process that animal such as duck, goose swims in the water, the web face is open during drying, leg when retraction web face but closes up, and people are in putting on the process that diving web diving advances, and both feet can only swing up and down and drive the web face and paddle, the web face but can't close up, therefore, resistance is big when advancing in water, and gait of march is slow.

Summary of the invention

The diving of the opening and closing automatically web that the purpose of this utility model provides a kind of resistance that can reduce water, advances fast.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of diving of opening and closing automatically web comprises the footwear body, and the sole edge of footwear body is connected with rubber web face, it is characterized in that: have reinforcement on the rubber web face; The sole edge is connected with upper limit plate and lower limiting board, and the upper limit plate is corresponding with lower limiting board, and the upper limit plate is positioned at the lower limiting board top, all has pin-and-hole on upper limit plate and the lower limiting board, is installed with pin in the pin-and-hole, interspersed described reinforcement on the pin.

According to the described diving of opening and closing automatically web, it is characterized in that: the end of described reinforcement has the connecting shaft folder hole, and pin passes from the connecting shaft folder hole.

Put on the utility model diving and can reduce the resistance of water to the people greatly, increase the propulsive force to water, web face folding and unfolding opening and closing can reduce diver's physical consumption freely, advance fast in water.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the mounting structure schematic diagram of reinforcement and upper limit plate among Fig. 1, lower limiting board.

In the accompanying drawing:

1, footwear body 2, rubber web face 3, reinforcement 4, pin 5, lower limiting board 6, upper limit plate

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is further described:

A kind of diving of opening and closing automatically web as shown in Figure 1 and Figure 2, comprises footwear body 1, and the sole edge of footwear body 1 is connected with rubber web face 2, has reinforcement 3 on the rubber web face 2; The sole edge is connected with upper limit plate 6 and lower limiting board 5, upper limit plate 6 is corresponding with lower limiting board 5, and upper limit plate 6 is positioned at lower limiting board 5 tops, all has pin-and-hole on upper limit plate 6 and the lower limiting board 5, be installed with pin 4 in the pin-and-hole, interspersed described reinforcement 3 on the pin 4.In the present embodiment, the end of reinforcement 3 has the connecting shaft folder hole, and pin 4 passes from the connecting shaft folder hole.

It is parallel with footwear body bottom surface that upper limit plate in the utility model is used for being controlled in the process of advancing in the water rubber web face, control rubber web face is no more than footwear body bottom surface, lower limiting board is that reinforcement and rubber web face reduce when advancing and the contact area of water in order to limit, the maximum constraints degree is that rubber web face is vertical with footwear body bottom surface, has reduced the resistance of water to human body and diving web greatly.

Footwear body in the utility model comprises welt, and welt one side is provided with porous to fan, and porous is to being installed with tight mouthful band in fanning, when the diver after wearing in the footwear body, can strain tight mouthful of band people's pin closely is connected with the web of diving under water.
