Description
Technical field
The utility model relates to athletics equipment field, refers to a kind of swim fin with bent joint especially.
Background technology
Flippers is a kind of can be the athletic equipment of swimming, the advance motive force providing powerful of diving under water, and the area that flippers is roomy can increase drying area for the pin of user in drying process, and then improves locomitivity.
Traditional flippers generally comprises footmuff and correspondence is positioned at the tiptoe portion web palm extended forward, and the general web of hard plastic plate or flexible rubber material that adopts of the web palm is made in conjunction with fulcra.Above-mentioned flippers also increases resistance during drying retraction while the foot for user increases drying area, therefore can consume the strength of user in a large number, be unfavorable for long-time use.
Utility model content
The purpose of this utility model is to provide a kind of swim fin with bent joint, its technical problem to be solved is: traditional flippers is while increase user foot drying area, also can increase the resistance that foot reclaims, and then the muscle power of user's leg can be consumed in a large number, be unfavorable for long-time use.
For solving the problems of the technologies described above, the utility model provides a kind of swim fin with bent joint, it comprises footmuff and the web palm, the described web palm comprises at least two fulcra and flexible web, the setting that the tiptoe position that described at least two fulcra correspondence is positioned at described footmuff extends forward, described flexible web stretches tight and supports between described at least two fulcra, fulcra described in every root are by least two the bone segment compositions be axially hinged, phase the same side that between described at least two bone segment, mutual corresponding one end is positioned at radial direction is provided with hinge, described at least two bone segment all can fold to the same side upset by relatively described hinge, on described flexible web, described in correspondence, at least two fulcra are respectively arranged with cross-under cover, described at least two fulcra are fixedly plugged in described cross-under cover respectively one to one, form the sole side of the corresponding described footmuff respectively of interconnective hinge between at least two of described fulcra bone segment.
Be preferable over: at least two hinged ends propped up between bone segment that described cross-under puts corresponding to described fulcra offer for the open section to two ends grafting, one end of described cross-under cover is fixedly connected on described footmuff.
Be preferable over: described fulcra are hard hollow pipe, be equipped with extension spring in described hard hollow pipe, the two ends of described extension spring are fixedly connected at least two bone segment metas of the described fulcra of composition respectively in the first two bone segment.
Compared with prior art, the beneficial effects of the utility model are: because at least two fulcra in the described web palm are made up of at least two bone segment, and the chain connection by flipping to one side between at least two bone segment, therefore the described web palm in use can assist foot's drying backward, when leg bounces back, the described web palm can bend as the articulations digitorum manus of duck's foot rolls up, and then reduces the resistance of retraction, reduces physical demands; Utilize the extension spring worn in described fulcra to make described fulcra automatically reply straight configuration in normal state, be convenient to next drying.

Detailed description of the invention
Below with reference to accompanying drawing 1 to 3 and preferred embodiment, a kind of swim fin with bent joint that the utility model proposes specifically is illustrated.
The utility model provides a kind of swim fin with bent joint, it comprises footmuff 1 and the web palm 2, the described web palm 2 comprises at least two fulcra 3 and flexible web 21, the setting that the tiptoe position that described at least two fulcra 3 correspondence is positioned at described footmuff 1 extends forward, described flexible web 21 stretches tight and supports between described at least two fulcra 3, fulcra 3 described in every root form by least two bone segment 31 be axially hinged, phase the same side that between described at least two bone segment 31, mutual corresponding one end is positioned at radial direction is provided with hinge 4, described at least two bone segment 31 all can fold to the same side upset by relatively described hinge 4, on described flexible web 21, described in correspondence, at least two fulcra 3 are respectively arranged with cross-under cover 22, described at least two fulcra 3 are fixedly plugged in described cross-under cover 22 respectively one to one, form the sole side of the corresponding described footmuff 1 respectively of interconnective hinge 4 between at least two of described fulcra 3 bone segment 31.
At least two hinged ends propped up between bone segment 31 described cross-under cover 22 corresponding to described fulcra 3 offer for the open section to two ends grafting, described fulcra 3 can plug in described cross-under cover 22 in described open section to two ends, one end of described cross-under cover 22 is fixedly connected on described footmuff 1.
Described fulcra 3 are hard hollow pipe, extension spring 5 is equipped with in described hard hollow pipe, the two ends of described extension spring 5 are fixedly connected on respectively at least two bone segment 31 of the described fulcra 3 of composition and are arranged in the first two bone segment 31, and then described fulcra 3 can be made under the elastic pulling force of extension spring 5 to keep straight configuration under normal conditions.
Described on comprehensive, the technical solution of the utility model fully effectively can complete above-mentioned utility model object, and structural principle of the present utility model and the principle of work and power are all verified in an embodiment fully, and effect and the object of expection can be reached, and embodiment of the present utility model also can convert according to these principles, therefore, the utility model comprise all in claim mention all replacement contents in scope.Any equivalence change done in the utility model claim, within the scope of the claims of all genus this case applications.
