Abstract
A folding bed under frame, which is provided with auto-locking function, belongs to a under frame device of a folding bed for enhancing the supporting and safety of the base. The utility model, which is composed of a quadrangle frame, a central crossing pole and turning joints, is characterized in that a folding locking mechanism is arranged at the crossing point of the central crossing pole, and a folding joint is positioned in the middle of every edges of the quadrangle frame, and a small joint is arranged at the four corners of the quadrangle frame. The frame is connected with a connecting pipe by two inversion symmetrical small joints, and the folding locking mechanism is buckled on the connecting pipe of the central crossing pole. The utility model is provided with safe and reliable usage and flexible and convenient folding.
Description
The utility model relates to a kind of folding bed underframe with the function of automatically locking, and it belongs to a kind of bottom reinforcing mechanisms of folding bed, improves the bulk strength of folding bed and the undercarriage arrangement of safety in utilization.
Existing folding bed, the folding bed used of children particularly, in order to guarantee that when opening and using the folding phenomenon that can not meet accident generally all is provided with a kind of locking device on the underframe of folding bed, constitute a underframe that can guarantee when opening and using, to have the folding bed of stable, safe user mode, this locking device all needs to open earlier locking mechanism in folding, finish folding action again, and its mechanism is numerous and diverse, operation sequence is many, and the cost of product is also higher.
The purpose of this utility model is to provide a kind of can will open locking mechanism and the folding bed underframe unites two into one, and simple in structure, flexible operation, the folding bed underframe with the function of automatically locking safe in utilization.
The purpose of this utility model is achieved in that
A kind of folding bed underframe with the function of automatically locking, it is formed by being tetragonal frame, central crossbar and turning joint, it is characterized in that being provided with folding mechanism for locking up at the infall of described central crossbar, the centre that is each limit of tetragonal frame is provided with a folding joint, be provided with little joint on described four angles that are tetragonal frame, the tube connector of frame and central crossbar is connected by the little joint of two reverse symmetry; Folding mechanism for locking up is fastened on the tube connector of central crossbar.Described folding mechanism for locking up is made up of loam cake, back-moving spring, pulling block and sliding shoe, is provided with cavity in described loam cake, and back-moving spring and sliding shoe place cavity, and pulling block is located at the center position of loam cake.Be provided with a drawstring on described pulling block, also be provided with a flexible wires on the pulling block, the other end of flexible wires is connected on the sliding shoe.Place, connectivity port at described tube connector is provided with plug in the pipe, and tube connector is connected by lock-screw with folding mechanism for locking up.Described little joint is a doubling cover, is provided with a chute hole and pin hole on the surface of hypozygal, and the bending part in described little joint is provided with the projection of symmetry, and constitutes a semi-enclosed pipe shape by the projection of described symmetry and the bending part in little joint.
The utility model is simple in structure, and is safe and reliable, amounts to convenient, flexible.The utility model can be applied in various folding beds, particularly children widely with on the folding bed.
