Rotating joint and game surrounding bed with rotating joint

Abstract

The invention discloses a rotating joint. The rotating joint comprises a first surrounding pipe and a second surrounding pipe, a joint shell rotationally connected with the first surrounding pipe through a first rotating shaft and rotationally connected with the second surrounding pipe through a fourth rotating shaft, and a locking mechanism for interlocking the first surrounding pipe, the second surrounding pipe and the joint shell, wherein limiting grooves and lock pin limit positioning grooves are formed in the left and right parts of the side surface of the joint shell; limiting pins are embedded in the limiting grooves; lock pins of the second surrounding pipe are embedded in the lock pin limit positioning grooves. The rotating joint is characterized in that the locking mechanism comprises a first locking dog in sliding arrangement with the first surrounding pipe in the length direction of the first surrounding pipe, and a second locking dog arranged on the second surrounding pipe; the lock pins of the second surrounding pipe are arranged in the lock pin limit positioning grooves of the joint shell; transverse extension grooves extend from the upper ends of the lock pin limit positioning grooves. The rotating joint enables the first surrounding pipe and the joint shell not to form the seaming state, so that a cloth cover covered on the outer layer is protected from being damaged through clamping.

Description

technical field [0001] The invention relates to a swivel joint and a play bed with the swivel joint. Background technique [0002] The traditional children's play bed has to be unfolded when it is used. It is large in size and convenient for children to use. It is folded when not in use. It is small in size and easy to store. Frequent folding puts forward high reliability requirements for the joints surrounding the bed. Not only is the folding operation easy, but also the joint locking requirements must be met when opening and using, so as to avoid causing harm to the baby. [0003] The original intention of the design of the foldable crib is to cover the bed frame with fabric. When unfolded, the cloth cover fits tightly to the bed frame. The use space is large and comfortable. If storage and travel are required, the bed frame must be folded to reduce the volume, so the bed frame When designing, there is a lockable folding joint on each of the four sides of the upper frame....
