Problems solved by technology

[0004] However, the combination of the child seat base and the car is particularly important. Although the existing child seat base can be closely combined with the car, it is extremely difficult to separate; and the role of the connecting rod in the link mechanism is very important, but the material of the connecting rod is single. Its strength and hardness are average, which cannot meet the wear resistance required by the connecting rod in the base, resulting in a short service life of the connecting rod, which in turn affects the service life of the base

Abstract

The invention relates to a base separation mechanism, and belongs to the technical field of machinery. The base separation mechanism comprises a front control portion, a rear control portion, a button and a connection mechanism. The front control portion comprises a front fixing piece and a front pull hook. The front fixing piece is provided with a front fixing block. The front pull hook is provided with a font hook piece. The rear control portion comprises a rear fixing piece and a rear pull hook. The rear fixing piece is provided with a rear fixing block, and the rear pull hook is provided with a rear hook piece. The button abuts against the front pull hook. The connection mechanism comprises a connection rod mounting groove and a connection rod arranged in the connection rod mounting groove and connected with the front pull hook and the rear pull hook in a hinged mode. The connection rod is made of carbon steel, and a machining process of the connection rod is specifically disclosed. The base separation mechanism is simple in structure and capable of conducting linkage unlocking, the whole base separation mechanism is easy and convenient to separate, the comprehensive mechanical performance of the connection rod is good, and thus the service life of the whole base separation mechanism is prolonged.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a base separation mechanism. Background technique [0002] In today's society, cars are becoming more and more popular, and almost every family has a car for transportation or travel. The safety of children in the car has aroused everyone's attention. [0003] Because children have no safety awareness, they need parents to supervise them, but parents may not be able to care about children for various reasons, so car child seats have been recognized by most parents. Put the child in the child seat, even if only one parent can take the child in the car. [0004] However, the combination of the child seat base and the car is particularly important. Although the existing child seat base can be closely combined with the car, it is extremely difficult to separate; and the role of the connecting rod in the link mechanism is very important, but the material of the connecting rod is sing...
