Description

Handle-adjusting device of carriage for children

The utility model relates to a kind of handrail angle regulator that is used on the perambulator.

Perambulator handrail control apparatus of the prior art is by a pair of tressel, a pair of fixed mount and latching device are formed, tressel and fixed mount pass through rivet, tressel can be rotated for axle around rivet with respect to fixed mount, tressel is captiveed joint with handrail, fixed mount is fixed on the vehicle body, by the angle between latching device locking tressel and the fixed mount, blocking device normally is equipped with the arc iron plate of a pair of edge indentation on the fixed mount, an iron rod is housed on the tressel slidably, iron rod is taken to be placed on and can be made tressel obtain different angles on the different teeth, the back-moving spring that is individually fixed on fixed mount and the iron rod by two ends can be stuck in the sawtooth iron rod tightly, with the purpose of the angle locking that reaches tressel.Though this structure is simple, the operation effort makes the user feel very inconvenient.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part, and a kind of perambulator handrail control apparatus easy to use is provided.

The purpose of this utility model can realize by following technical proposal:

The utility model is made up of tressel, fixed mount and blocking device, and tressel and fixed mount flexibly connect by axle.Tressel is connected with handrail, and fixed mount is connected with vehicle body.Blocking device comprises: the lock slider between tressel and fixed mount, this lock slider radially have a sliding tray, axle passes from the sliding tray of lock slider, the groove width of described sliding tray is slightly larger than the diameter of the axle that is positioned at sliding tray, so that lock slider can radially slide with respect to axle; Projection on the lock slider; Be the circumferential protrusion in the center of circle with the axle on the fixed mount, have a breach that can embed the lock slider upper protruding block on the described circumferential protrusion at least; Be loaded on the spring between sliding tray inwall and the axle; Be fixed in the case that can rotate with respect to fixed mount on the tressel, have a hole on the described case, lock slider radially extends through this hole and is exposed at outside the case.When outside case, pressing lock slider, lock slider slides with respect to axle along sliding tray, makes projection break away from breach, and this moment, lock slider can sway along the edge of the circumferential protrusion on the fixed mount, because lock slider passes the hole of case, sways so lock slider can drive tressel; When lock slider in rotation process, projection can run into another breach on the circumferential protrusion, leans on the pressure projection of spring can enter this breach, and lock slider just can not sway again, tressel also is positioned on this position by lock slider, makes tressel with respect to the fixed mount angle locking.

The utility model compared with prior art has following advantage:

Embed the angle orientation that breach reaches handrail by projection, only need press the angle that lock slider can change handrail, so very convenient, laborsaving during use.

Case can cover the actuating mechanism of blocking device, and is safer during use.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing 1 is the structural front view of an embodiment of the present utility model;

Accompanying drawing 2 is the structure birds-eye view of an embodiment of the present utility model;

Accompanying drawing 3 is the A-A direction cutaway view of accompanying drawing 1;

Accompanying drawing 4 is the B-B direction cutaway view of accompanying drawing 2;

Wherein: 1. fixed mount; 2. lock slider; 3. breach; 4. spring; 5. circumferential protrusion; 6. sliding tray; The axle; 8. case; 9. tressel; 10. projection;

Embodiment one: with reference to accompanying drawing, lock slider 2 is between tressel 9 and fixed mount 1, this lock slider 2 radially have a sliding tray 6, axle 7 passes from the sliding tray 6 of lock slider 2, described sliding tray 6 is wide strip shape through hole, its groove width is slightly larger than the diameter of the axle 7 that is positioned at sliding tray 6, so that lock slider 2 can radially slide with respect to axle 7; Axle 7 can serve as with screw, so that tressel 9 and fixed mount 1 and lock slider 2 are linked together; The columnar shaft of a hollow can also axially be set on fixed mount 1, and this columnar shaft is enclosed within on the screw, and columnar shaft passes the sliding tray 6 in the lock slider 2 more then, and the groove width of sliding tray 6 should be slightly larger than the diameter of columnar shaft at this moment.One projection 10 is arranged on the lock slider 2; Having on the fixed mount 1 with axle 7 is the circumferential protrusion 5 in the center of circle, and this circumferential protrusion 5 is the annulus of a projection at this, has a breach 3 that can embed lock slider 2 upper protruding blocks 10 on the annulus, also more breach can be set according to the needs of armrest lock allocation.Sliding tray 6 inwalls are provided with the spring groove that can place spring 4, and this spring groove is that a groove longer than sliding tray is set in sliding tray 6 inwalls.The spring 4 that compresses can be contained between the end wall of the axle 7 and the close projection 10 of sliding tray 6, have breach 3(such as accompanying drawing on the edge, the nearly center of circle (being the inward flange of annulus) of the protruding circular ring on the fixed mount 1 at this moment), projection 10 on the lock slider is the axle center dorsad, to cooperate with breach 3 on the annulus.Another kind method is that the spring 4 that compresses is contained between the end wall away from projection 10 of axle 7 and sliding tray 6, this is protruding circular ring for circumferential protrusion 5(on the fixed mount 1) the edge (being the outward flange of protruding circular ring) in the center of circle far away on have breach 3, this moment, the projection 10 on the lock slider was towards the axle center, to cooperate with breach 3 on the annulus.Case 8 is an one with tressel 9, connection by axle 7 can be rotated case with respect to fixed mount 1, have a hole on the described case 8, this hole is slightly larger than lock slider, lock slider 2 radially extends through this hole and is exposed at outside the case 8, be exposed on the end face of the part lock slider 2 outside the case 8 and be carved with skidproof lines, as the button part of manual manipulation lock slider 2.Case 8 is a tubular, and its oral area is buckled on the fixed mount 1, and lock slider 2 and circumferential protrusion 5 are covered, and can prevent that hand or other article from being choked, and reaches safe effect.
