Description

Novel baby crib bottom middle seat mechanism Technical Field The utility model relates to the technical field of crib components, in particular to a novel crib bottom middle seat mechanism. Background The existing folding crib generally adopts a structure that a middle base at the bottom is rotationally connected with a bottom fork tube to realize the folding function. For example, patent publication CN217827349U proposes a base structure of a crib, which enables folding and unfolding of a bottom fork tube by a return spring. However, this structure has the following drawbacks: 1. The spring is relied for resetting, the assembly installation precision requirement is high, and the assembly is complicated; 2. After long-term use, the spring is easy to fatigue, so that the locking is unstable; 3. the operation steps are complex, and the use of the user is inconvenient. Therefore, there is a need for a baby crib bottom middle seat mechanism with simple structure, convenient operation and stable locking. Disclosure of utility model The utility model aims to provide a novel baby crib bottom middle seat mechanism, which solves the problems of complex structure, inconvenient operation and unstable locking in the prior art by optimizing the design of a locking component.
