Description
Technical field
The present invention relates to doors to have field, more particularly to a kind of door handle, the door and its door knob of effective regulation handle height
Hand-made Preparation Method is particularly suitable for children's use.
Background technique
Due to the height of children, in the places such as children room, amusement park, kindergarten, the door handle of the door tool used
Height should than normal door have door handle setting height it is lower.Existing door tool is all made of the preparation of international or national standard,
It is difficult to effectively be suitable for children.Simultaneously because the height of children is constantly to get higher, and therefore, the door handle of existing door tool
Height be fixed to be difficult to effectively adjust.
On the other hand, since child height is lower, formaldehyde it is heavier than air, be mainly suspended in apart from 1 meter or so of ground height
Position is spent, this height is just the breathing height of children, therefore formaldehyde is affected to children.In existing door tool, formaldehyde
Content is minimum for Solid Door, wood-plastic door.Wherein wood-plastic door is to be mixed using the ultra-fine powder of timber with macromolecule resin, passes through mould
Plasticizing process is fabricated, and has the good characteristic of timber and plastics concurrently, and the product of production has achieved the effect that real imitation wood.Due to
The raw material and production process used does not use glue to bond, and will not generate the harmful substances such as formaldehyde, benzene, ammonia, trichloro ethylene, be
Substitute the environmental protection new material of traditional timber.Plastic-wood material is compared with wood materials: water absorption rate is low, is unlikely to deform cracking,
Anti-moth-eating mildew, have mechanical performance is high, light, moisture-proof, acid and alkali-resistance, it is corrosion-resistant, convenient for cleaning.
And want the effective height for adjusting door handle, need door handle and door have will have it is certain on-deformable
Characteristic, and be easy to adjust.Therefore wood-plastic door is the first choice having suitable for the door of children, is the trend of future development, is current sheet
The hot spot of area research.
The primary raw material of wood-plastic door is polyvinyl chloride resin and high-quality wood powder, is handled by sizing screening, grinding, drying, coating,
Guarantee requirement of the finished product to material quality.It is furnished with a certain proportion of auxiliary material in wood-plastic door formula system, stabilizer, hair is added
Infusion, modifying agent etc., various compositions are mixed by stringent proportion, effectively guarantee the product quality of foaming plate.
Summary of the invention
The technical problem to be solved by the present invention is to, 1, existing door handle height be difficult to adjust, not being suitable for children makes
With；2, existing door handle, door tool are easily-deformable, are unable to reach adjustable effect；3, door knob made of existing Wood-plastic material
Hand plasticity, anti-deformation are poor, it is difficult to be effectively used for door handle and door tool.
In order to solve the above technical problems, the present invention provides a kind of door handle, including handle member, several connectors；It is described
