Description
Technical field
The utility model relates to bend wood chair base nut pre-buried structure, has related in particular to a kind of bend wood chair base nut pre-buried structure and bend wood chair.
Background technology
At present, often adopt on base after perforate the bonding nut between existing song seat base and stool pin or nut is screwed in base, then by screw, base being connected with the stool pin.Owing to adopting the glue bonding between nut and base, its load that bears is limited, and As time goes on, glue also can come off gradually, thereby causes nut to drop.And when being screwed in nut on base, of long duration, also can cause screw cap-falling along with the wearing and tearing of base internal thread, thereby cause chair normally to use.
Summary of the invention
The utility model is during for being connected between bend wood chair in prior art and base, the nut that is arranged in base easily comes off, affect the shortcomings such as bend wood chair service life, a kind of counterbore that arranges in base is provided, nut is arranged in counterbore, effectively avoided nut to come off in base, a kind of bend wood chair base nut pre-buried structure and the bend wood chair that have extended the service life of bend wood chair.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Bend wood chair base nut pre-buried structure comprises base and stool foot support, and base comprises face glued board and primer plywood, and described primer plywood is provided with counterbore, is provided with nut in counterbore, coordinates with nut by screw between base and stool foot support to be fastenedly connected.
As preferably, described counterbore is four, and counterbore is the T font.Nut is arranged on the top of T font counterbore.
As preferably, described nut is the four paws nut, and four claws of four paws nut embed in the primer plywood.Therefore, be fixed together firmly between four paws nut and base, then when spinning screw, nut can not rotate yet, and makes the installation of base and stool foot support more efficient and convenient.
As preferably, also be provided with cushion block between described base and stool foot support.Because the bottom surface of base has certain radian, therefore, by being set, cushion block can effectively adjust distance between base and stool foot support, and make the stool foot support can guarantee that the height of four stool pin is identical in the process of installing.On the other hand, cushion block adopts plastics to make, and can play certain cushioning effect, has avoided the direct contact wear of stool pin and base.
As preferably, described primer plywood is comprised of the glued board more than two.
Bend wood chair comprises above-described bend wood chair base nut pre-buried structure.
As preferably, described bend wood chair also comprises backrest.
The utility model is owing to having adopted above technical scheme, have significant technique effect: the utility model is by arranging counterbore in base, be fixed on firmly nut in base, unless whole base is torn, otherwise nut can't be taken out, therefore greatly strengthen the bonding strength of base and stool foot support, improved product service life.
