The intensity of chair back connector is effectively increased by the setting in " V " shape section.
Preferably, being additionally provided with one in first connecting portion for connecting the link block of the chair back.The setting of link block is further
The intensity for increasing first connecting portion, not only increases degree of deflection resistance, also to facilitate connection, mounting hole is located at link block
On, it is external more beautiful without exposing mounting hole in first connecting portion.
In order to guarantee the comfort level of user, preferably, the angle of both the first connecting portion and second connecting portion
Range is between 80 ° -100 °.
Preferably, the first connecting portion includes the first side plate and the second side plate, V-arrangement is formed between two side plates
Slot；The link block is triangular prism, and the link block is arranged in V-shaped groove.
The link block is also possible to plane, i.e. tabular link block, the purpose is to connect V-shaped groove two sides, to increase
Connection is added to sit the intensity of part.
Further, two faces of the link block and two medial surfaces of V-shaped groove are affixed along its length；And the company
Block is connect to be welded and fixed with first connecting portion.By the setting of link block, the intensity of chair back connector is further increased.
Further, a groove is additionally provided on the link block.The groove helps to mitigate the weight of link block, reaches section
The purpose of material saving.
Preferably, the first connecting portion, second connecting portion are the molding of steel plate integrated punching.
Preferably, setting on the link block, there are four the mounting holes for installing the chair back.
Preferably, the second connecting portion two sides are respectively provided with two for installing the mounting hole for sitting part.
Preferably, further including the curved transition sections for connecting first connecting portion and second connecting portion.The intermediate location
For arc, guarantee safety when using.
A kind of seat, including the chair back, sit part and chair back connector as described above, the chair back include back frame and
Support frame, support frame as described above is in Y-shape, the secondary support that connect respectively with back frame two sides including two and connect with back frame lower part
Main support, the main support connect with link block, and the seat part is connect with second connecting portion.
The beneficial effects of the utility model are: the utility model uses the setting in " V " shape section, and it is not only beautiful, also increase
The intensity of chair back connector to reduce the thickness of steel plate has saved raw material.The setting of link block further enhances
The intensity of chair back connector, to achieve the purpose that save material.
