Description

Technical Field

[0001] The utility model belongs to the technical field of polyurethane foaming devices, in particular to a polyurethane foaming tool assembly device. Background Art

[0002] Polyurethane can be foamed to produce polyurethane foam material. This material is widely used in many industries due to its excellent insulation, sound insulation, cushioning and durability. It has almost penetrated into all sectors of the national economy, especially in furniture, bedding, transportation, refrigeration, construction, insulation and other sectors. It has become one of the indispensable materials.

[0003] The existing authorization announcement number is CN217494940U, which is an annular plug for foaming an insulation pipe and an insulation pipe foaming device. The insulation pipe foaming device includes a platform and an annular plug. The platform is used to support the outer tube of the insulation pipe to be foamed, and the annular plug is used to seal the end of the annular space between the outer tube and the inner tube of the insulation pipe to be foamed. A tightening structure is provided on the outer tube, and the tightening structure is a carriage spring lock buckle. The carriage spring lock buckle includes a lock buckle and a handle. A vertical plate hinge part and a lock buckle hinge part are provided on the handle. The vertical plate hinge part is hinged on the vertical plate, and the lock buckle is hinged on the lock buckle hinge part of the handle. A spring is also provided between the lock buckle and the handle. After the lock buckle is hung on the arc-shaped hanging ear, the handle is lifted up and passes through the fixed position between the lock buckle and the arc-shaped hanging ear and between the vertical plate and the handle. The lock buckle is locked on the arc-shaped hanging ear by relying on the dead point principle to align the two pairs and parts.

[0004] Although the above-mentioned carriage spring lock buckle can lock the foaming device, since the arc-shaped hanging ear is a sheet-like hanging ear, it will cause the hanging ear to deform during long-term use or excessive pressure during use, resulting in failure to lock, and external tools are required to separate the outer shell, which makes disassembly inconvenient.
