Half frame wheel posture Breaststroke slider
Technical field
The present invention relates to a kind of slide plate, the half frame wheel posture Breaststroke slider that particularly a kind of both feet do not land, bipod stands on this slide plate, the twisting bipod just can make it to move ahead.
Technical background
Also can't seek on the market Breaststroke slider at present, the Breaststroke slider that the design people formerly designs, what adopt is two panels, the front portion of two plate faces connects with connecting rod, it is collapsible that the connecting rod middle part utilizes folder to connect, two, front and back of two panels bottom respectively connects a universal wheel, and this can also simpler and more joint letter on structure and cost.
Summary of the invention
The objective of the invention is to provide the half frame wheel posture that a kind of structure is simpler, cost is lower Breaststroke slider.The object of the present invention is achieved like this: half frame wheel posture Breaststroke slider, comprise half frame wheel carrier, two front-wheels, two forks, two panels and two universal wheels, it is characterized in that: half frame wheel carrier is that two that the metal bending of a flat strip shaped becomes the outside at the two ends of half shaped as frame, half frame respectively to connect a front axle, half frame top margin respectively connects a minor axis and forms, two front-wheels are socketed on two front axles of half frame wheel carrier, the front end sleeve of Two fork is connected on two minor axises of half frame wheel carrier, the bottom of Two fork rear end connects two universal wheels, connects two panels on the Two fork.
The invention has the beneficial effects as follows: the manufacturing of this product is simple, cost is low, draw expansion in conveniently, and the speed that slides is faster.

The specific embodiment
According to Fig. 1, described three-wheel Breaststroke slider comprises half frame wheel carrier 1, front-wheel 2, fork 3, panel 4 and universal wheel 5;
Described half frame wheel carrier 1 comprises half shaped as frame metal flat bar, two front axles and two minor axises, the top of described front axle and described minor axis is all with threaded hole, the outside at the two ends of described half shaped as frame metal flat bar respectively connects a described front axle, and two of described half shaped as frame metal flat bar top margin respectively connects a described minor axis.
Described front-wheel 2 is PU wheels of plastic wheel hub, and the core wheel of described PU wheel has two bearings, and two described front-wheels 2 are socketed on the two described front axles of described half frame wheel carrier 1, and is fastened in the screwed hole on two described front axle tops with two bolts that how to fall.
Described fork 3 comprises rectangular tube, bearing ring, bearing, Universal castor and punching with holes, described rectangular tube is the level metal rectangular pipe that the upper undershoot of front and back end has arc opening, described bearing ring is welded in the front end of described rectangular tube, described bearing is embedded in the described bearing ring, described castor base is the threaded tube shape metal piece of endoporus, described castor base is welded on the rear end of described rectangular tube, described castor base slightly right-falling stroke is drawn and is retreaded, the top of described rectangular tube front and rear part is welded with described punching with holes, two described bearing holder (housing, cover)s of two described fork 3 front ends are connected on the two described minor axises of described half frame wheel carrier 1, and are fastened in the screwed hole on two described minor axis tops with two bolts that how to fall.
Described panel 4 is by being formed by plastic injection-moulded, the decorative pattern that the plate face of described panel 4 is comprised of the antiskid particles of projection, there is the eyelet corresponding with the punching described with holes of described sliding bar 3 at the back side of described panel 4, and described panel 4 is connected with the punching described with holes of described fork 3 by bolt.
Described universal wheel 5 comprises a Universal castor and PU wheel, described Universal castor is by a bolt, one bearing, one wheel fork and a circle disk consist of, described bearing is embedded in the top of described wheel fork, described circle sheet and described top riveted joint of having inlayed the wheel fork of bearing, one of described bolt with the described brearing bore socket that is connected in the wheel fork top, thereby make described Universal castor, described PU wheel is by being rotationally connected lock bolt and described Universal castor, and two described universal wheels 5 are fastened to respectively in the screw of two described Universal castors of two described forks, 3 rear ends.
