Description

a detachable flipper

Technical field

The utility model relates to a shoe, in particular to a detachable flipper for amphibious use, which can be used during diving and walking on land.

Background technique

Fins are important equipment used by people in snorkeling. They allow swimmers to get more effective driving force in the water by kicking their legs. The general fins are made of foot covers (used to fix flippers to divers). On the foot) and the front of the drowning water (providing the diver's propulsion in the water); the traditional flipper's foot cover and the sloping forefoot are an inseparable whole, and the underside of the foot cover and the forefoot is at The same horizontal plane is molded by rubber. The flippers of this structure are in the same horizontal plane because the soles of the feet and the bottom of the forefoot are in the same horizontal plane. The product has a single use and can only be used in water. When the body is idle (for example, walking on land), it cannot be used reasonably, especially Because the overall length of the flippers is too long, it is not convenient to carry, so it is inconvenient to use. Moreover, since the rubber is used for one-time injection molding, the wearing feeling is not good, and it is easy to fall off when diving, and it is not comfortable to wear.

The utility model patent with the application number CN200920061419.2 discloses a separate type of flipper, which comprises a foot cover and a water-repellent sheet, and the water-repellent film is assembled on the foot cover through a detachable locking mechanism. The two sides of the water-repellent sheet integrally extend forwardly from the two reinforcing ribs, and the locking mechanism includes a first connecting buckle and a second connecting buckle that is engaged with the first connecting buckle, and the first connecting buckle is fixed to the 蹼The rear end of the rib of the water piece, the second connecting buckle is correspondingly mounted on both sides of the foot cover. The foot cover includes a soft rubber shoe body and a hard rubber plate that is fused under the body portion, and the first connecting buckle is mounted on the hard rubber plate. The same side of the foot cover is sequentially provided with a card slot, a buckle and a rear sliding block, and the second connecting buckle is correspondingly provided with a rib, a card hole and a limit. a slot, the card hole is composed of a large hole and a small hole, and when the second connecting buckle is assembled, the buckle slides into the small hole along the large hole of the hole, and the rib is inserted into the slot, and the limit is limited. The bit slot slides into the rear slider.

The split flipper has the characteristics of being convenient to carry and flexible to use, but it also has the following problems:

1. The foot cover of the split flipper comprises a soft rubber shoe body and a hard rubber plate which is fused under the shoe body portion, and the connecting buckle is assembled on the hard rubber plate, which has the disadvantages of complicated structure and troublesome assembly.

2. The water-repellent sheet between the two reinforcing ribs of the separated flipper protrudes forward with a row of limiting ribs, and the corresponding front end of the foot sleeve is correspondingly provided with a plurality of fitting grooves, and the limiting ribs are correspondingly inserted into the In the recessed groove, when the component is disassembled, due to the problem of the design of the rubber sleeve material and the snap-fit structure, the sealing property and the waterproof property of the joint portion are problematic.

3. The split flipper adopts a soft rubber shoe body and a hard rubber plate which is fused under the shoe body. Due to the material of the shoe upper, the user has the disadvantage of poor heat preservation effect when diving in deep water.
