The folding and unlocking mechanism of the rear wheel support of the children's tricycle separates the lower part of the rear wheel support fixing part from the upper part of the rear wheel support fixing part by twisting the bolts between the components, and separates the rear joint of the bottom rod from the lower joint of the rear lower push rod, thereby enabling the components to move, thereby achieving the function of folding the entire vehicle frame. After the entire vehicle is folded, the volume is small and it is convenient for people to carry.
而基于上述的现有技术，目前现有的儿童三轮车的旋转折叠解锁结构还存在以下问题，现有的儿童三轮车通常采用固定的车架结构，使得存放和携带不便，虽然市场上存在一些可以折叠的儿童三轮车，但其折叠解锁结构往往支撑性能不好，为此，本实用新型提供了一种儿童三轮车的旋转折叠解锁结构。Based on the above-mentioned prior art, the rotating folding and unlocking structure of the existing children's tricycle still has the following problems: the existing children's tricycle usually adopts a fixed frame structure, which makes storage and carrying inconvenient. Although there are some foldable children's tricycles on the market, their folding and unlocking structures often have poor supporting performance. Therefore, the utility model provides a rotating folding and unlocking structure for a children's tricycle.

连接组件22，设置于套筒组件21的右端，并用于使套筒组件21与右插入组件23之间连接。The connecting assembly 22 is disposed at the right end of the sleeve assembly 21 and is used to connect the sleeve assembly 21 and the right inserting assembly 23 .
本实施例中，套筒组件21还包括开设在左螺纹柱211顶部和底部的通孔213，通孔213的内部滑动安装有滑动压柱214。In this embodiment, the sleeve assembly 21 further includes through holes 213 formed at the top and bottom of the left threaded column 211 , and a sliding pressure column 214 is slidably installed inside the through hole 213 .
通过十字滑块215带动左连接块216与双向连接块221，进入或拉出左螺纹柱211的内部，且双向连接块221的两端分别铰接左连接块216与右连接块233，从而实现左螺纹柱211与右螺纹柱231之间折叠，从而儿童三轮车体积减小，便于携带和存放。The left connecting block 216 and the two-way connecting block 221 are driven by the cross slider 215 to enter or pull out of the interior of the left threaded column 211, and the two ends of the two-way connecting block 221 are respectively hinged to the left connecting block 216 and the right connecting block 233, so that the left threaded column 211 and the right threaded column 231 can be folded, so that the volume of the children's tricycle is reduced, which is convenient for carrying and storage.
本实施例中，连接组件22包括与左连接块216铰接安装的双向连接块221，双向连接块221的顶部和底部开设有圆孔222，圆孔222的内部滑动安装有顶柱223，顶柱223在圆孔222内的一端固定安装有挤压弹簧224。In this embodiment, the connecting component 22 includes a two-way connecting block 221 hingedly mounted to the left connecting block 216, and circular holes 222 are provided at the top and bottom of the two-way connecting block 221. A top column 223 is slidably mounted inside the circular hole 222, and an extrusion spring 224 is fixedly mounted at one end of the top column 223 in the circular hole 222.
按压两个滑动压柱214，两个滑动压柱214对两个顶柱223进行挤压，顶柱223对挤压弹簧224进行挤压，从而使双向连接块221与左螺纹柱211进行脱离。The two sliding pressure columns 214 are pressed, and the two sliding pressure columns 214 press the two push columns 223 , and the push columns 223 press the pressing springs 224 , so that the two-way connecting block 221 is separated from the left thread column 211 .
本实施例中，右插入组件23包括铰接安装在双向连接块221右端的右连接块233，右连接块233的右端固定安装有右螺纹柱231，右螺纹柱231的外圈螺纹转动安装有螺纹套筒232。In this embodiment, the right insertion component 23 includes a right connecting block 233 hingedly installed on the right end of the two-way connecting block 221, a right threaded column 231 is fixedly installed on the right end of the right connecting block 233, and a threaded sleeve 232 is rotatably installed on the outer circle thread of the right threaded column 231.
在左螺纹柱211与右螺纹柱231对接时转动螺纹套筒232，使螺纹套筒232套住左螺纹柱211与右螺纹柱231，从而实现左螺纹柱211与右螺纹柱231之间的固定连接，从而确保在折叠和展开过程中，结构能够保持稳固，不易松动，能够提供较强的抗拉力，有效防止因受力不均或外力冲击导致的松动或断裂。When the left threaded column 211 and the right threaded column 231 are connected, the threaded sleeve 232 is rotated to make the threaded sleeve 232 cover the left threaded column 211 and the right threaded column 231, thereby realizing a fixed connection between the left threaded column 211 and the right threaded column 231, thereby ensuring that during the folding and unfolding process, the structure can remain stable and not easy to loosen, and can provide strong tensile resistance, effectively preventing loosening or breakage caused by uneven force or external force impact.
本实施例中，顶柱223滑动插入通孔213的内部。In this embodiment, the top column 223 is slidably inserted into the through hole 213 .
本实施例中，连接组件22滑动插入套筒组件21的内部。In this embodiment, the connecting component 22 is slidably inserted into the interior of the sleeve component 21 .
同时本说明书中未作详细描述的内容均属于本领域技术人员公知的现有技术。Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.
工作时，首先在展开时，十字滑块215带动左连接块216与双向连接块221进入到左螺纹柱211的内部，此时挤压弹簧224通过自身的弹力推动顶柱223，此时顶柱223的圆弧端插入通孔213内部，而左螺纹柱211的右端与右螺纹柱231的左端接触，转动螺纹套筒232，使螺纹套筒232螺纹转动套装在左螺纹柱211与右螺纹柱231连接的地方，完成展开；During operation, first, when unfolding, the cross slider 215 drives the left connecting block 216 and the two-way connecting block 221 to enter the interior of the left threaded column 211. At this time, the extrusion spring 224 pushes the top column 223 by its own elastic force. At this time, the arc end of the top column 223 is inserted into the through hole 213, and the right end of the left threaded column 211 contacts the left end of the right threaded column 231. The threaded sleeve 232 is rotated to make the threaded sleeve 232 threadably rotate and fit at the connection between the left threaded column 211 and the right threaded column 231, and the unfolding is completed;
然后在折叠时，反向转动螺纹套筒232，使螺纹套筒232脱离左螺纹柱211的外圈，接着按压两个滑动压柱214，两个滑动压柱214对两个顶柱223进行挤压，顶柱223对挤压弹簧224进行挤压，此时拉动右螺纹柱231，使右连接块233带动双向连接块221拉出左螺纹柱211的内部，左螺纹柱211以左连接块216与双向连接块221转动连接点为轴心九十度逆时针转动，右螺纹柱231以右连接块233与双向连接块221转动连接点为轴心九十度顺时针转动，完成折叠。Then, when folding, the threaded sleeve 232 is rotated in the opposite direction to disengage the threaded sleeve 232 from the outer ring of the left threaded column 211, and then the two sliding pressure columns 214 are pressed, and the two sliding pressure columns 214 squeeze the two top columns 223, and the top column 223 squeezes the squeezing spring 224. At this time, the right threaded column 231 is pulled, so that the right connecting block 233 drives the two-way connecting block 221 to be pulled out of the interior of the left threaded column 211, and the left threaded column 211 rotates counterclockwise for 90 degrees with the rotation connection point of the left connecting block 216 and the two-way connecting block 221 as the axis, and the right threaded column 231 rotates clockwise for 90 degrees with the rotation connection point of the right connecting block 233 and the two-way connecting block 221 as the axis, and the folding is completed.
