The plurality of wriggling sections are connected via hinges, the screw rod is arranged inside the plurality of wriggling sections and driven by an electric speed reducing mechanism to rotate so as to lead the wriggling sections to swing left and right in a curve form, the wriggling device is pushed forwards via wriggling of the wriggling sections and a tail fin, and wriggling is lively and vivid and can achieve the effect of mixing the false with the genuine especially when the device wriggles in water. The bionic fish wriggling device brings unlimited entertainment and enjoyment to players, has the unique advantages of novel and unique inventive conception, simple and reasonable structural design, easy manufacturing, convenient maintenance, reliable performance, low cost, high resistance to manmade sabotage, and national and international pure mechanical transmission type bionic fish manufacturing, and can be combined with a fish head, a fish-shaped yacht and the like to manufacture a large-size bionic fish, a riding type wriggling bionic fish, a bionic fish yacht, a wriggling bionic fish toy and the like, thereby having wide applicability and attractive development prospect.

Description

Bionical fish vermiculator

Technical field

The utility model belongs to the biomimetic peristaltic device of amusement in the water, recreation use, the lifelike image of especially wriggling, recreational extremely strong mechanical type biomimetic peristaltic device in water.

Background technology

Present domestic bionical fish vermiculator, the also discovery as yet of pure mechanical drive form fabrication and installation.Once developed the electronic bio fish in the U.S. and domestic university, but on market, do not applied yet.The key of electronic bio fish is the biomimetic peristaltic device.The biomimetic peristaltic device of the electronic bio fish of above-mentioned university development adopts electronics package to control, structure is quite complicated, and the electronic bio fish a common shortcoming is arranged is the cost height, it is difficult to make, need that the professional safeguards, anti-artificial destruction is poor.Especially the artificial destruction that is difficult to resist in the place of public amusement will make whole bionical fish in paralyzed state in case have a bit to destroy, thereby lose the amusement effect.

Summary of the invention

The utility model provides a kind of bionical fish vermiculator, and complex structure, cost height, the making that purpose is to solve existing bionical fish vermiculator existence is difficult, inconvenience is safeguarded, the problem of anti-artificial destruction difference.

Described bionical fish vermiculator is to constitute by hinged a plurality of wriggling joints with at the inner screw rod that is provided with of a plurality of wriggling joints.

Described screw rod is the individual transmission shaft that is made of straight line and helix line one, and drives its rotation by the electric reducer structure.

Described wriggling joint is wide at the top and narrow at the bottom, pre-large post-small shape such as ellipse shape housing, a frame board that is provided with centre hole is fixed in front end or rear and front end at ellipse shape housing, the attaching parts that corresponding circular arc depression and boss are formed before and after being provided with respectively at the two ends up and down of ellipse shape housing.

Outstanding feature of the present utility model is to be provided with screw rod and the wriggling joint of a plurality of flexible connections of being driven by screw rod, and under the drive of electric reducer structure, in the process of screw rod rotation, making the wriggling joint make curvilinear figure swings, and utilize the peristalsis propels of wriggling joint and tail fin to move ahead, wriggling lifelike image, the especially actual effect that moves ahead of wriggling in water can be brought unlimited recreational and interesting to the people.Moreover, also have the novel uniqueness of inventive concept, structure design advantages of simple, easily make easy to maintenance, dependable performance is with low cost, anti-artificial destruction is strong and the unique advantage of the bionical making fish of domestic and international pure mechanical transmission-type.It can combine with fish head, fish shape yacht etc. and make large simulated fish, rider the formula with a wide range of applications and fine development prospects such as bionical fish, bionical fish yacht and the bionical fish toy of wriggling of wriggling.

The specific embodiment

Bionical fish vermiculator of the present utility model is the bionical fish vermiculator of a kind of mechanical transmission-type, it has a plurality of wriggling joints 1, described wriggling joint 1 is the housing by shape wide at the top and narrow at the bottom, pre-large post-small such as ellipse, fix a frame board 2 that is provided with centre hole at the front end of ellipse shape housing, the connector that corresponding circular arc depression and boss are formed before and after being provided with respectively at the two ends up and down of ellipse shape housing.Wherein first wriggling joint 1 with second and other each wriggling save 1 slightly different, difference is that frame board 2 centre holes of the first wriggling joint 1 are circular hole, and second and other each wriggling joint 1 centre hole be vertical cylindrical void, and last wriggling joint 1 is that the rear and front end of tail fin all is provided with frame board 2 and is the centre hole of cylindrical void.In 1 ellipse shape housing of the first wriggling joint, also be provided with support plate with holes in addition, and all installed light material additional in each wriggling joint 1 housing, in order to regulate the sink-float position of vermiculator in water.On the cooresponding circular arc depression in the two ends up and down of ellipse shape housing and front and back and boss, be provided with axis hole, through bearing pin, packing ring and spring cotter several wriggling joint 1 hinges be connected by axis hole.Make it to form a mobilizable integral body.Since second wriggling joint 1, the centre hole of other each wriggling joint 1 frame board 2 is all to be provided with Rolling bearing 3 in vertical cylindrical void, this Rolling bearing 3 is made up of two parts of relative pressing, the pressing mouth is dovetail form and embeds, Rolling bearing 3 centers are through hole, there is chamfering at the through hole edge, and the outer radial center is provided with annular groove, and annular groove is embedded on the described cylindrical void edge.Rolling bearing 3 can just move up and down in the cylindrical void freely at the centre hole of frame board 2.Be provided with a screw rod 4 in a plurality of wriggling joints inside, described screw rod 4 is individual transmission shafts that are made of straight line and helix line one.The screw rod end is inserted from preceding frame board 2 centre holes of first wriggling joint 1, pass a plate hole, pass through second wriggling joint 1 and other through hole on the Rolling bearing 3 to some wrigglings joint 1 its frame board 2 cylindrical voids between tail fin again, make screw rod 4 front ends cross first frame board, 2 centre holes, and it is spacing in the support plate both sides by axle bush, outer axle housing, pad, jump ring.Described screw rod 4 drives its rotation by the electric reducer structure.Screw rod 4 should be rotated by the direction of setting, and must not reverse.Rolling bearing 3 slides up and down in cylindrical void under the effect of screw rod 4 during screw rod 4 rotations, and forces wriggling joint 1 to swing by the position-limiting action of Rolling bearing 3 and cylindrical void.Screw rod 4 and cylindrical void limit up and down leaves enough spaces, does not make screw rod 4 arrive two limits up and down, and the dynamic birds-eye view of described screw rod 4 rotations is a curvilinear figure, and this curve promptly is the wriggling form of wriggling joint 1.It also is wriggling form of the present utility model.Because the curve of screw rod 4 is slick and sly and rotate the effect that it is produced and reached bionical fish wriggling fully, and has realized that the wriggling of bionical fish moves ahead, especially in water, the image degree of mixing the spurious with the genuine that reaches more true to nature.
