(3) summary of the invention
The purpose of this utility model is the one-hand fold complex structure that will solve existing doll carriage, and part is many, and volume is big, operating difficulties, reliability is low, and the shortcoming that cost is high provides a kind of reliability height, and part is few, volume is little, and is easy to assembly, the one-hand fold device of the doll carriage that cost is low.
The technical scheme that the prior art problem that solves the utility model is adopted is:
A kind of one-hand fold device of doll carriage, comprise handrail, the first preceding push rod, the second preceding push rod, first rear linking rod and second rear linking rod, two ends of described handrail are affixed with the front end of the first preceding push rod, the second preceding push rod respectively, the rear end of push rod, the second preceding push rod is connected with upper joint before described first, the affixed hypozygal of leading portion of described first rear linking rod, second rear linking rod, upper joint and hypozygal are hinged; Socket has the handle of inner chamber on the described handrail, described handle is provided with the safety switch that the control handle rotates, the drive block affixed with handle is installed in the inner chamber of described handle, is positioned at the left slider and the right slide block of drive block two sides, the driving surface that described drive block contacts with left and right slide block is the inclined-plane and arranges, the driving surface of described left and right sides slide block and the driving surface of drive block coupling, described left slider, right slide block have pushed up reseting pressuring spring respectively away from drive block one end, all are connected with trailing cable on the described left and right slide block; Described upper joint with the left slider bonded assembly trailing cable and the first preceding push rod is connected, and is connected with the upper joint of push rod before right slide block bonded assembly trailing cable and second, and the sense of motion of described upper joint, the corresponding trailing cable of hypozygal is provided with the projection and the groove of working in coordination.
The push rod and the second preceding push rod are hollow structure before the described handrail, first, and described trailing cable is located in handrail and first, second preceding push rod.
Safety switch on the described handle is the safety block affixed with handle, and described safety block is provided with projection, and left slider is provided with the chute that cooperates with projection.
Described projection is positioned at hypozygal, and described groove is positioned at upper joint.
The utility model has the advantages that: rotate by handle and drive the drive block rotation, thereby make and left and right sides slide block bonded assembly upper joint disengaging hypozygal, and then folding just passable, simple to operate, convenient; Simple in structure, the reliability height, part is few, and volume is little, and is easy to assembly, and cost is low.
(4) description of drawings
Fig. 1 is the utility model overall schematic;
Fig. 2 is the utility model joint part enlarged diagram;
Fig. 3 is the scheme drawing of handle structure.
(5) specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
As Figure 1-3, a kind of one-hand fold device of doll carriage, comprise handrail 14, first preceding push rod 15, the second preceding push rod, first rear linking rod 16 and second rear linking rod 26, two ends of described handrail are affixed with the front end of the first preceding push rod, the second preceding push rod respectively, the rear end of push rod, the second preceding push rod is connected with upper joint 17 before described first, the affixed hypozygal 18 of the leading portion of described first rear linking rod, second rear linking rod, upper joint and hypozygal are hinged; Socket has the handle 6 of inner chamber on the described handrail, described handle is provided with the safety switch that the control handle rotates, the drive block 4 affixed with handle is installed in the inner chamber of described handle, is positioned at the left slider 5 and the right slide block 3 of drive block two sides, the driving surface that described drive block contacts with left and right slide block is the inclined-plane and arranges, the driving surface of described left and right sides slide block and the driving surface of drive block coupling, described left slider, right slide block have pushed up reseting pressuring spring 9 respectively away from drive block one end, all are connected with trailing cable 2 on the described left and right slide block; Described upper joint with the left slider bonded assembly trailing cable and the first preceding push rod is connected, be connected with the upper joint of push rod before the right slide block bonded assembly trailing cable and second, the push rod and the second preceding push rod are hollow structure before the described handrail, first, and described trailing cable is located in handrail and first, second preceding push rod; The sense of motion of described upper joint, the corresponding trailing cable of hypozygal is provided with the projection 19 and the groove 20 of working in coordination, and described projection is positioned at hypozygal, and described groove is positioned at upper joint.Safety switch on the described handle is the safety block 10 affixed with handle, and described safety block is provided with projection 21, and left slider is provided with the chute that cooperates with projection.
As shown in Figure 3, the right safety switch 10 of dialling of the application of force, make the projection 21 of safety block break away from chute on the left sliders, rotate handle 6 then, handle drives drive block 4 and rotates, and to the extruding left and right sides, both sides slide block 3,5, left and right sides slide block drives on the upper joint 17 by trailing cable 2 and moves drive block by the inclined-plane, thereby hypozygal is broken away from, handrail is rotated get final product.
