Abstract
A ratchet unit with a function of reverse locking is characterized in that a round ratchet surface is provided with a recessed surface which is formed by connecting a plurality of arc corners; the center of the recessed surface is provided with a shaft hole; a controller is arranged on the recessed surface; a moving shift fork and a shaft are arranged on the controller. The ratchet unit allows rubber wheels of a trolley to rotate forward in the same direction and never reversely rotate; the ratchet unit is time saving and labor saving, effective in using, simple in structure and flexible to operate.
Description
Affiliated technical field
The present invention relates to a kind of be arranged on manual type single wheel waggon axletree, prevent go-cart from going up a slope while stopping wheel fall back along slope can reverse locking ratchet group.
Background technology
At present in the middle of the daily life of rural area, it is the most general something that grain is received on steep kind ground, when pushing away goods and materials steep, people all want interval, because dolly can be to slope lower slider under the effect of gravity, at this moment will look for often stone or other thing pads under wheel, just have no time to free hand to look for thing pad wheel when a people operates sometimes at all, can only be that the dolly that pushing away of effort is stood and had a short break, one dolly of loosing one's grip will fall back, like this and danger require great effort again.
Summary of the invention
In order to solve the problem of above-mentioned proposition, the invention provides a kind of ratchet group that can reverse locking, this can reverse locking ratchet group, can make the rubber wheel above waggon rotate forward by same direction, backwards rotation phenomenon can not occur, time saving and energy saving, result of use is good, and simple in structure, flexible operation.
The object of the present invention is achieved like this, ratchet group that can reverse locking, be round wheel surface and be provided with a groove surface that is connected together and forms by a plurality of arc corner angle, centre is provided with an axis hole, on groove surface, be provided with a controller, controller is provided with a movable shift fork, an axle, during use, first runner is fixed on the center shaft of rubber wheel, again with the axle on controller by the axis hole on runner, controller is fixed in the groove surface on runner, movable shift fork on controller is just in time stuck in the corner angle on runner, if rotating forward, rubber wheel will drive runner and then to rotate forward, on runner, the movable shift fork of controller will be got back along arc corner angle, if the runner on rubber wheel rotates backward, on runner, the movable shift fork of controller will erect to withstand runner and not allow runner rotate backward, thereby reach the runner effect that stands fast of only advancing, simple in structure, easy to operate.
Feature of the present invention is, the movable shift fork of controller on runner, when rotating forward, will get back along arc corner angle, only have runner to rotate forward, the movable shift fork of controller on runner, when rotating backward, will erect to withstand runner and not allow runner rotate backward, simple in structure, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is left view of the present invention.
In figure: 1, runner; 2, corner angle; 3, groove surface; 4 axis holes; 5, controller; 6, shift fork; 7, axle.
The specific embodiment
Below in conjunction with front view, the present invention is further illustrated.
In view, be round runner 1 surface and be provided with a groove surface 3 that is connected together and forms by a plurality of arc corner angle 2, centre is provided with an axis hole 4, on groove surface 3, be provided with a controller 5, controller 5 is provided with a movable shift fork 6, an axle 7, during use, first runner 1 is fixed on the center shaft of rubber wheel, the axis hole 4 passing through on runner 1 with the axle 7 on controller 5 again, controller 5 is fixed on to 3 li of groove surfaces on runner 1, movable shift fork 6 on controller 5 is just in time stuck in 2 li, corner angle on runner 1, if rotating forward, rubber wheel will drive runner 1 and then to rotate forward, on runner 1, the movable shift fork 6 of controller 5 will be got back along arc corner angle 2, if the runner on rubber wheel 1 rotates backward, on runner 1, the movable shift fork 6 of controller 5 will erect to withstand runner 1 and not allow runner 1 rotate backward, thereby reach 1 effect that stands fast of advancing of runner, simple in structure, easy to operate.
