Abstract

The disclosure discloses a sofa armrest connection structure and a sofa assembly. The connection structure includes a first member and a second member, wherein the first member includes a first base plate, two guide rails symmetrically arranged on the first base plate, and a limiting part which is arranged on the first base plate and located under the two guide rails; the second member includes a second base plate and two guide bars symmetrically arranged on the second base plate; the two guide bars are in sliding insertion-fit with the two guide rails correspondingly; the first base plate and the second base plate are each provided with a plurality of bolt holes; the first base plate is used for being connected with a sofa seat frame, and the second base plate is used for being connected with a sofa armrest.

Claims (29)

1. A sofa armrest connection structure, characterized by comprising a first member ( 11 ) and a second member ( 12 ), wherein the first member ( 11 ) comprises a first base plate ( 111 ), two guide rails ( 112 ) symmetrically arranged on the first base plate ( 111 ), and a limiting part ( 113 ) which is arranged on the first base plate ( 111 ) and located under the two guide rails ( 112 ); the second member ( 12 ) comprises a second base plate ( 121 ) and two guide bars ( 122 ) symmetrically arranged on the second base plate ( 121 ), and the two guide bars ( 122 ) are in sliding insertion-fit with the two guide rails ( 112 ) correspondingly;

the first base plate ( 111 ) and the second base plate ( 121 ) are each provided with a plurality of bolt holes ( 114 );

the first base plate ( 111 ) is used for being connected with a sofa seat frame ( 2 ), and the second base plate ( 121 ) is used for being connected with a sofa armrest ( 3 );

alternatively, the first base plate ( 111 ) is used for being connected with the sofa armrest ( 3 ), and the second base plate ( 121 ) is used for being connected with the sofa seat frame ( 2 );

characterized in that the second base plate is also of a shape of a long strip plate, and the guide bars are of third bent structures formed by bending side edges of the second base plate toward one surface of the second base plate;

and the third bent structures are of the shape of “n”.

2. The connection structure according to claim 1 , characterized in that the first base plate ( 111 ) is of a shape of a long strip plate, and the guide rails ( 112 ) are of first bent structures formed by bending side edges of the first base plate ( 111 ) toward one surface of the first base plate ( 111 ); the limiting part ( 113 ) is of a second bent structure formed by bending a side edge, close to an end, of the first base plate ( 111 ) toward one surface of the first base plate ( 111 ); and the first bent structures and the second bent structure are bent toward a same surface of the first base plate ( 111 ).

3. The connection structure according to claim 1 , characterized in that a distance between the two guide rails ( 112 ) gradually decreases along an axial direction of the first base plate ( 111 ).

4. The connection structure according to claim 1 , characterized in that a distance between the two guide bars ( 122 ) gradually decreases along an axial direction of the second base plate ( 121 ).

5. A sofa assembly, characterized by comprising the sofa armrest connection structures ( 1 ) according to claim 1 , a sofa seat frame ( 2 ) and sofa armrests ( 3 ), wherein:

the sofa seat frame ( 2 ) comprises two symmetrically-arranged cross beams ( 22 ) and two longitudinal beams ( 21 ) connected with the two cross beams ( 22 ); and each longitudinal beam ( 21 ) comprises a first supporting plate ( 211 ) and a first side plate ( 212 ) arranged on one side of the first supporting plate ( 211 );
