Description

Outdoor wood-plastic stool strip

Technical Field

The utility model relates to an outdoor bench strip technical field specifically is an outdoor wood is moulded bench strip.

Background

Most of stool surfaces and stool bars adopted in the existing garden buildings are made of steel or cement or wood or bamboo, but the problems of resource waste, high cost, short service life and the like generally exist.

In recent years, with the development of wood-plastic industry, some wood-plastic stool surfaces are also appeared. The wood plastic composite material is a novel composite material which is briskly developed in recent years at home and abroad, and particularly relates to a plate or a section which is produced by mixing polyethylene, polypropylene, polyvinyl chloride and the like instead of a common resin adhesive with more than 35-70% of waste plant fibers such as wood flour, rice hulls, straws and the like to form a new wood material, and then carrying out plastic processing processes such as extrusion, die pressing, injection molding and the like. The wood-plastic composite material contains plastics, so that the wood-plastic composite material has a better elastic modulus. In addition, because the fiber is contained and fully mixed with the plastic, the wood-plastic composite material has physical and mechanical properties such as compression resistance, bending resistance and the like which are equivalent to those of hardwood, has high surface hardness, and has durability which is obviously superior to that of common wood materials.

The existing wood-plastic bench strip is usually a common solid bench strip, is heavy, is easy to fade, age, absorb water, swell and the like when being irradiated by sunlight, has poor durability, and is easy to crack and fade when being used in the open air.

Disclosure of Invention

In order to overcome the not enough of prior art scheme, the utility model provides a bench is moulded to outdoor wood alleviates the quality of itself, and stability is better, can postpone ageing and fracture and fade etc. is fit for outdoor use, can the effectual problem that the solution background art provided.

The utility model provides a technical scheme that its technical problem adopted is:

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the utility model provides an outdoor wood-plastic stool strip, including stool body basic unit 1 and through compound resin bonding and the wood-plastic stool body 2 of stool body basic unit 1 formation integral structure, the upper surface of stool body basic unit 1 is provided with two sets of connecting grooves 13 that are X type skew, and is in be provided with two sets of protruding 14 of being connected with connecting grooves 13 interlock on the face of being connected of wood-plastic stool body 2 and stool body basic unit 1, connecting grooves 13 and connect and be equipped with shrink clearance 12 between the arch 14.

The 3 fixed connection of the type of returning hook of 1 both sides in the stool body basic unit through fixed mounting on the lateral wall of stool body basic unit 1 and wood-plastic stool body 2, and the corner of stool body basic unit 1 and wood-plastic stool body 2 all gets up wood-plastic stool body 2's edge protection through the cladding of chinese character ' shan style of calligraphy angle bead 4, will be easily protected by the corner of wearing and tearing in addition through chinese character ' shan style of calligraphy angle bead 4 further, but also can prevent sharp-pointed corner scotch human body.

Through composite resin's adhesive action and returning the type hook connection, the equipment and the dismantlement of the bench body basic unit 1 of being convenient for and the wood-plastic bench body 2 because the life of the wood-plastic bench body 2 often is short in bench body basic unit 1, in order to effectively utilize bench body basic unit 1, can tear out the type hook that returns when the wood-plastic bench body 2 is impaired to peel off the composite resin who is used for the bonding, directly change the wood-plastic bench body 2, thereby continue to utilize bench body basic unit 1.

The stool body is moulded to wood 2 inside cavity bar holes 5 that are equipped with a plurality of evenly distributed, 5 port departments of cavity bar holes all have self tapping closure stopper 9 through screw thread movable mounting, and be equipped with the support column 6 that a plurality of is parallel to each other on the cross section of the stool body is moulded to wood 2, the stool body is moulded to wood 2 be equipped with two sets of mutual skew and be the shrink groove 7 of U style of calligraphy on the surface, and all be equipped with coextrusion membrane 8 with the upper surface of the stool body is moulded to wood in shrink groove 7.

And be equipped with a plurality of support columns 6 that are parallel to each other on the cross section of wood-plastic stool body 2, wood-plastic stool body 2 is equipped with two sets of contraction tanks 7 that are the U style of calligraphy of crossing each other on the surface, and the contraction tank 7 that the surface set up can prevent the surface fracture that leads to because expend with heat and contract with cold, and all is equipped with coextrusion membrane 8 in contraction tank 7 and wood-plastic stool body 2's upper surface, makes its ageing resistance better, is difficult for taking place the fracture and discolours.

Hollow bar hole 5 that sets up can effectually alleviate the quality of wood bench body 2, it is big to overcome solid bench body quality, the poor defect of bearing capacity, and can also reduce the use of raw and other materials, when the temperature variation difference is big, because the existence in hollow bar hole 5, can make wood bench body 2 have the space of expend with heat and contract with cold, prevent because the direct mutual extrusion of inner structure leads to bad effects such as bench body fracture, and further set up the distribution in hollow bar hole 5, make hollow bar hole 5 inside not contain the moisture, prevent that ponding from being corroded.

As shown in fig. 3, the self-tapping closing plug 9 comprises a flat head screw 15 and a rubber plug 16 fixedly mounted at the end of the flat head screw 15, a plurality of groups of mutually parallel backflow ditches 10 are arranged on the flat head screw 15 along the axial direction of the flat head screw, and an insect-proof net rack 11 is arranged at the joint of the backflow ditches 10 and the rubber plug 16.

The utility model discloses in, grub screw 15 is through with the screw thread want the interlock effect to fix in cavity strip hole 5 to be equipped with backward flow ditch 10 on automatic bolt 15's surface, make at closed in-process, grub screw 15 and cavity strip hole 5 have banding clearance, the aqueous vapor in the cavity strip hole 5 of being convenient for spills over. Therefore, in the present embodiment, the self-tapping closing plug 9 actively closes the opening, and the backflow groove 10 and the insect net frame 11 are used in combination, so that the water inside can be discharged and insects can be prevented from entering the opening.

To sum up, the utility model discloses a key feature lies in:

(1) compared with the original solid wood-plastic stool strip, the porous structure of the utility model reduces the consumption of raw materials and the weight of the stool strip, so that the weight of the stool strip can be increased, and the structure is more stable and is not easy to deform when expanding with heat and contracting with cold;

(2) the surface of the bench strip is additionally provided with the layer of co-extruded film, so that the bench strip is better in aging resistance and not easy to crack and fade, and the shrinkage groove arranged on the surface can improve the resistance to expansion with heat and contraction with cold, so that cracking is avoided.
