Adjustment mechanism and child safety seat having the same

Abstract

An adjusting mechanism for adjusting the length of a telescopic supporting leg 100 includes an adjusting assembly comprising engaging member 21, engaging portions 421, a driving member 23 and an operating member 25. The engaging member 21 and operating member 23 are at opposite ends of a supporting pipe 41 which is telescopically adjustable relative to another pipe 42. The other pipe 42 has engaging portions 421 formed as holes in its side walls to allow discreet staged longitudinal lengthening or shortening of the support leg 100. The operating member 25 acts as a handle to operate adjustment at a remote end of the pipe 41. The driving member pushes a seat against a resilient spring 24 to urge engaging member 23 laterally inward as locating pins 28 are guided along oblique driving slots 231 to release the adjustment mechanism. Buttons 251 of the operating member 25 have oblique slanted faces 252 which urge cooperating oblique faces 233 of the driving member 23 to release the engaging member 21. The supporting leg can be used as a child car safety seat support leg (fig 1). A second adjusting mechanism (30, fig 11) can be provided with pivoting engaging members 311 to engage with the engaging portions 421.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to an adjustment mechanism and a child safety seat with the adjustment mechanism. Background technique [0002] With the continuous progress of society, the continuous development of economy, and the continuous improvement of science and technology, people are provided with more and more abundant consumer goods, thereby creating extremely excellent material conditions for improving people's living standards, and children's vehicles are many consumer goods One of. Among them, among the children's vehicles, since the child safety seat not only has the advantages of comfortable ride, but also can provide safety protection for the child, the child safety seat is more and more popular among people. [0003] As we all know, when installing and fixing a child safety seat on a load such as a car seat, it is necessary to support the child safety seat through the supporting feet arranged at the botto...

Problems solved by technology

[0004] However, in the current market, the length of the supporting feet of the child safety seat is often fixed. When the child safety seat is installed on loads such as car seats of different sizes, the supporting feet of the child safety seat are often If the length is too long or too short, the supporting legs cannot play a supporting role, thus causing the supporting legs to fail to assist the installation and fixing of the child safety seat well, making the installation and fixing of the child safety seat unstable and reliable, causing The installation and fixation of child safety seats brings potential safety hazards, and even causes harm to children riding in child safety seats, thus reducing the safety of riding

In addition, there is also a support foot whose length can be adjusted and changed on the market to adapt to child safety seats installed on loads such as car seats of different sizes and specifications. However, the structure for adjusting the length of the support foot is extremely complicated. The cost is very expensive, the operation process of adjusting the length of the supporting legs is extremely cumbersome and inconvenient to use, and the structure is not reliable, and there are also potential safety hazards. It is far from meeting the needs of users, seriously affecting the use of users and child safety seats. promotion and popularization of
