Description
Technical field
The utility model relates to a kind of cardan wheel, relates in particular to a kind of cardan wheel with blocking device.
Background technology
As everyone knows, in the hand push conveying arrangement, normally install castor additional, turn to for ease, can on a side of working direction, through ship be installed usually, on hand push one side cardan wheel is installed in hand push conveying arrangement bottom.For example: hand push conveying arrangement bottom adopts three-wheel to arrange; Be to arrange two castors on the working direction; Arrange a castor on the hand push direction, two castors on working direction, arranging usually are through ship, move along a straight line in order to guarantee the hand push conveying arrangement; A castor of on the hand push direction, arranging is a universal caster wheel, in order to the sense of motion of control hand push conveying arrangement; Hand push conveying arrangement bottom adopts four-wheel to arrange; Be to arrange two castors on the working direction; Also arrange two castors on the hand push direction, two castors on working direction, arranging usually are through ship, move along a straight line in order to guarantee the hand push conveying arrangement; Two castors on the hand push direction, arranging are universal caster wheel, in order to the sense of motion of control hand push conveying arrangement.This mounting means; Can guarantee that the hand push conveying arrangement well moves along a straight line, and adjusting motion direction easily, but it can only be carried out forward from a direction; If will oppositely carry out; Can only carrying out forward, cause great inconvenience with behind the hand push conveying arrangement Rotate 180 ° to the user.
In order to solve this mode that can only unidirectional propelling; People all change the outfit into cardan wheel with castor; So, though solved the problem of the two-way propelling of hand push conveying arrangement, it is difficult to grasp the direct of travel of good luck hand push conveying device; Move and be difficult to also have the problem of carrying out inconvenience along the straight line implementation.
At present; In order to solve these awkward problems that above-mentioned cardan wheel exists, make the easy to use and operation of hand push conveying arrangement, adopt of people installed this method of blocking device additional to cardan wheel more; Make that cardan wheel both can the anglec of rotation; Be convenient to the hand push conveying arrangement and change sense of motion, can be locked as through ship again, make the hand push conveying arrangement well to carry out along straight line.
Disclose a kind of location cardan wheel like Chinese patent document CN202060991U, it is close to the resistance circle through the resistance pin under the effect of brute spring, and slides along the circumference of resistance circle; The resistance circle is fixedly mounted on the cardan wheel, and has groove above that, when cardan wheel rotates to certain angle; Pin just in time with the resistance circle on groove relative, pin is stuck in the groove, and the resistance circle is fixed; Thereby make the cardan wheel location, and can only be along the sense of motion straight-line motion of hand push conveying arrangement, when cardan wheel need turn to; Only need enforce the hand push conveying arrangement, just can make pin in groove, skid off, thereby realize turning to of hand push conveying arrangement.Though it has solved the problem that above-mentioned cardan wheel exists, also there is certain problem in himself, as: the cardan wheel registration device is too complicated, and locating effect is bad, and pin skids off in groove easily.
Chinese patent document CN201158275Y discloses a kind of cardan wheel registration device for another example, and it matches with centre hole on the cardan wheel rotating disk through the socket cap on the fix shaft, realizes the locking and unlocking of cardan wheel.Its actv. has solved the problem that above-mentioned cardan wheel exists, and locking effect is better, but its blocking device is comparatively complicated; And need the user manually to control turning handle, fix shaft is discharged, and make socket cap cooperate locking with centre hole on the cardan wheel rotating disk; When release, also need manually control turning handle simultaneously, fix shaft is packed up; Its operation is too loaded down with trivial details, is unfavorable for that the user uses.
