Abstract
The utility model relates to a handcart whose pushing direction can be conveniently controlled. A vertical shaft of a front universal wheel of the utility model is provided with a brake apparatus. When the utility model advances in a fixed direction, the brake apparatus is in a brake state for limiting the rotation of the vertical shaft; when the traveling direction of the utility model needs to be changed, the brake apparatus is in a relaxed state, and the vertical shaft can be freely rotated. The brake apparatus is composed of a convex thrust which is fixed on the vertical shaft of the universal wheel and a sliding plate which is provided with a groove with a shape coinciding with the shape of the convex thrust, wherein the convex thrust has a circular smooth head, and the sliding plate can move forwards and backwards. A controlling handgrip of the utility model is a bow-shaped rod whose both ends are fixed on an armrest bracket.
Description
The design belongs to the light industrial goods field, particularly a kind of hand barrow of being convenient to control the implementation direction.
The widely used various hand barrows that support and advance by cardan wheel of people, as supermarket shopping cart, airdrome luggage car and perambulator etc., they are supported by forward and backward two groups of cardan wheels.Its advantage is to turn to very convenient, flexiblely, and can advance along any direction.Simultaneously, also there is some shortcoming in it, and for example, when people are intended to will find that dolly not too obedient when a certain circuit is carried out forward, always left avertence is turned right, and is difficult to control.
The design is exactly the improvement of carrying out at this shortcoming, makes it both to keep turning to originally convenient, flexible advantage, can be easy to keep direction again when carrying out.
This design is that a brake gear is installed on the vertical shaft of the cardan wheel in hand barrow the place ahead.When it needs directed moving ahead, brake gear is placed braking mode, be unlikely to deflection with the rotation of restriction vertical shaft; When it need change direct of travel, brake gear is placed relaxed state, vertical shaft can rotate freely, so that adjust direction.
The control handle of brake gear is that two ends are fixed on the arch bar on the armrest support.Arch bar places under the handrail, so that handle.As shown in Figure 1: 1 is preceding cardan wheel; 2 is brake gear; 3 is arch bar; 4 is hauling rope; 5 is the back cardan wheel.
A kind of brake gear that relatively is suitable for is by the protruding thorn of a head slyness on the cardan wheel vertical shaft before being fixed on and have with the sliding panel that moves around of the corresponding to groove of protruding thorn shape and formed.Have pilot bar, retracing spring, draw bar on the sliding panel and be connected tensioning spring on the draw bar etc.Its structure is as shown in Figure 2: 1 is tensioning spring; 2 is draw bar; 3,7 is orienting sleeve; 4 is sliding panel; 5 is retracing spring; 6 is pilot bar; 8 is preceding cardan wheel vertical shaft; 9 is protruding thorn; 10 is groove.
When the desire go-cart moved ahead, hand was grabbed on the arch bar and is carried, and the traction sliding panel moves to stop to the vertical shaft direction, and groove entangles protruding thorn, thereby the rotation of restriction vertical shaft is to keep direction.If groove fails to entangle protruding thorn during tensioning, the protruding thorn point of cardan wheel meeting automatic compensation relies on the forbearing and conciliatory groove that enters of tensioning spring towards the groove direction of sliding panel when then moving ahead, and the locking vertical shaft.
In addition, brake gear also can be selected the device of the other types that adapt with its installing space for use.When the direct of travel of cardan wheel during towards the dead ahead, stop vertical shaft, can keep direction equally.
Claims (3)
1, a kind of being convenient to controlled the hand barrow of carrying out direction, it is characterized in that being equipped with one on the vertical shaft of its preceding cardan wheel can limit the brake gear that vertical shaft rotates freely.
2, as claimed in claim 1 being convenient to controlled the hand barrow of carrying out direction, and the control handle that it is characterized in that its brake gear is that two ends are fixed on the arch bar on the armrest support, so that handle.
3, as claimed in claim 1ly be convenient to control the hand barrow of carrying out direction, a kind of brake gear that it is characterized in that it is by the protruding thorn of a head slyness on the cardan wheel vertical shaft before being fixed on and have consistent with protruding thorn shape so that the sliding panel that moves around of the groove that protruding thorn embeds is formed.Have pilot bar, retracing spring, draw bar on its sliding panel and be connected tensioning spring on the draw bar etc.
