Telescopic-type connection device and child car seat

Abstract

The invention discloses a telescopic-type connection device, which is arranged on a child car seat. The telescopic-type connection device comprises a fixed frame, control elements and a group of connection rods, wherein the fixed frame is installed in the base of the child car seat, the connection rods are slidably installed on the fixed frame and capable of stretching out and retreating in relative to the base, and linkage rods are connected among the connection rods; and the fixed frame is provided with a plurality of clamping parts along the stretching-retreating direction of the connection rods; clamping and fixing elements matched with the clamping parts are installed on the linkage rods; the control elements are installed on the linkage rods and used for controlling the clamping and fixing elements to be clamped with or separated from the clamping parts. The telescopic-type connection device can be used for adjusting the stretching-retreating lengths of the connection rods. The invention discloses the child car seat simultaneously.

Description

technical field [0001] The invention relates to a telescopic connection device and a child car seat, in particular to a telescopic connection device and a child car seat capable of adjusting the telescopic length of a connecting rod. Background technique [0002] When the child is still in the infant period under six months, it is difficult to sit and stand, and most of them mainly lie down and cannot directly ride in a car. If an adult rides in a car with a child in his arms, when an accident occurs, the safety of the child cannot be guaranteed. For this reason, developers have developed a child car seat that caters to the use in the car. [0003] Existing children's car seats generally include a seat base, a seat body fixed on the seat base, and a very popular ISO FIX (International Standards Organization FIX, International Standards Organization FIX) fixing device. The ISO FIX fixing device is fixedly connected with the seat base, and the child car seat is reliably conne...

Problems solved by technology

[0004] However, the existing ISO FIX fixing devices are generally fixedly connected to the seat base, and cannot be stretched relative to the seat base. In this way, on the one hand, when the child car seat is in a non-use state, the volume of the parts Larger, occupying a larger space is not conducive to packaging; in addition, during transportation, because the engaging part of the ISO FIX connecting rod of the ISO FIX fixing device protrudes forward, it is easy to be damaged due to collisions, etc., which is not conducive to improving Safety and reliability when connected and used; on the other hand, because different models of cars have different seats, child car seats cannot be applied to all models, and sometimes the child car seat may be damaged because the connecting rod is too short or too long. It is placed on the front or back, and even because the connecting rod is too short or too long, it cannot be normally installed on the seat in the car and can only be fixed with a shoulder strap (sometimes only a waist belt), which will cause great harm to the children in the car. security risks
