The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 1-Figure 10, this furniture hinge comprises the holder 2 that joins with wallboard 1; The sliding seat 4 of joining with door-plate 3; Holder 2 is connected with link assembly through linking arm 5 with sliding seat 4, and link assembly comprises first connecting rod 6, second connecting rod 7, third connecting rod 8 and the 4th connecting rod 9, and third connecting rod 8 and the 4th connecting rod 9 are hinged; And be respectively arranged with first connector 11 and second connector 12; Be provided with angle retainer 10 between two connectors, it is characterized in that second connector 12 and angle retainer 10 each other against, be provided with rolling member between the two.
In the present embodiment, the design of rolling member is: angle retainer 10 corresponding positions of sliding with second connector, 12 crotches are provided with opening B 10.1, and rolling member is connected on the opening B through bearing pin B 14, and rolling with the crotch of second connector 12 is connected.Scratch, press phenomenon such as collapse for fear of between the rolling member and second connector 12, therefore the hardness of second connector 12 (crotch) and rolling member quite (the preferred aluminium alloys of material, kirsite, iron, stainless steel and other metal materials).Likewise, rolling member can adopt following design, is specially: the corresponding position of sliding with angle retainer 10 of the crotch of second connector 12 is provided with opening A, and rolling member is connected on the opening A through bearing pin A, and rolling with angle retainer 10 is connected.Because rolling member is positioned on the crotch; Therefore the angle retainer 10 of this mode can be made by whole employing metal material (preferred aluminium alloys, kirsite, iron, stainless steel and other metal materials); Perhaps angle retainer 10 adopts plastic production to form; Again in its surface coverage one deck metal level suitable (preferred aluminium alloys, kirsite, iron, stainless steel and other metal materials) with second connector, 12 intensity; To satisfy the suitable requirement of hardness of angle retainer 10 and rolling member, avoid scratching, press phenomenon such as collapse.Two kinds of technique effects that design reached are identical, adopt according to actual conditions.
In the present embodiment, rolling member is roller 15, also can adopts roller or bearing.The same preferred aluminium alloys of the manufacturing materials of rolling member, kirsite, iron, stainless steel and other metal materials.
Linking arm 5 is connected with holder 2; The first, an end of third connecting rod is hinged with the middle part and the front end of linking arm respectively; The first, the other end of third connecting rod is hinged with an end of the second, the 4th connecting rod respectively; The second, the other end of the 4th connecting rod is hinged with sliding seat 4 respectively, and the middle part of second connecting rod is also hinged with the middle part of third connecting rod.Linking arm 5 is the channel-section steel type, and its inner chamber is provided with damper 16, and the cylinder body 16.1 of damper is fixed in the inner chamber of linking arm 5.
Between the utility model second connector and the angle retainer rolling member is set; Thereby change sliding friction between the two into rolling friction, significantly reduce friction factor, rolling member and angle retainer (surface) or second connector (crotch) adopt the suitable material of hardness to form; Avoid it to scratch each other or press the phenomenon of collapsing; Can be original several times through the hinge opening and closing testing time, increase the service life significantly, meet the relevant criterion of use.
The operating principle of the utility model is: referring to Fig. 1-Fig. 4, when hinge was closed, piston rod 16.2 retraction cylinder bodies 16.1 formed buffering, and an end of the crotch of second connector 12 and angle retainer 10 interlocks, and promptly crotch fastens roller 15.Referring to Fig. 5, Fig. 6, when hinge was opened, the roller 15 of the crotch of second connector 12 and angle retainer 10 rolled each other, and the piston rod 16.2 of damper 16 stretches out cylinder body 16.1 towards sliding seat 4 directions, prepared for cushioning next time.
