The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure: this refrigerator sliding door is with interior trailer structure; It comprises rail 3 and sliding door locking plate 9 in the sliding door; Orbiting end plate 31, interior tread side plate 32 and interior flange of rail side plate 33 in rail 3 comprises in the described sliding door; The tip edge portion of orbiting end plate 31 in interior tread side plate 32 one are connected, the bottom edge portion of orbiting end plate 31 in interior flange of rail side plate 33 one are connected; On interior orbiting end plate 31, offer sliding door installing hole 34; Tail end at interior orbiting end plate 31 is provided with sliding door locking plate installing hole 35; The upper surface of interior tread side plate 32 be provided with superposed in rail rolling ball track 36; Lower surface at interior flange of rail side plate 33 is provided with the rail rolling ball track 36 that is positioned at the bottom, the rail amount of pulling out limiting plate 37 in the stage casing of interior orbiting end plate 31 is provided with; The interior rail rolling ball track 36 of interior tread side plate 32 upper surfaces cooperates the complete interior rail rolling ball track upper track of formation with the interior rail rolling ball track of middle tread side plate upper surface; The interior rail rolling ball track 36 of interior flange of rail side plate 33 lower surfaces cooperates road under the complete interior rail rolling ball track of formation with the interior rail rolling ball track of middle flange of rail side plate lower surface.
Described sliding door locking plate 9 comprises the locking plate epipleural 9.1 and locking plate lower side panel 9.2 that head end portion one connects; The upper wall of the lower wall of locking plate epipleural 9.1 and locking plate lower side panel 9.2 is combined to form one section groove; The cell wall of said groove seamlessly transits, and the upper wall of the lower wall of locking plate epipleural 9.1 and locking plate lower side panel 9.2 joins at the groove bottom land; On locking plate epipleural 9.1 or locking plate lower side panel 9.2, offer locking plate installing hole 9.3, the lower wall leading section of locking plate epipleural 9.1 is connected with locking plate projection 9.4, and the antetheca and the rear wall of locking plate projection 9.4 are combined to form parabolic shape; Locking plate lower side panel 9.2 antethecas in locking plate projection 9.4 summit the place aheads and the antetheca of locking plate projection 9.4 are combined to form horn mouth;
The securing member of packing in locking plate installing hole 9.3 and the sliding door locking plate installing hole 35 is fixed on sliding door locking plate 9 tail end of rail 3 in the sliding door.
Rail indentation amount limiting plate 38 in the head end of interior orbiting end plate 31 is provided with.The width of rail indentation amount limiting plate 38 is greater than the width of interior tread side plate 32 in said, and the width of interior tread side plate 32 is consistent with the width of interior flange of rail side plate 33.On interior orbiting end plate 31, offer expanding unit installing hole 39 near interior rail indentation amount limiting plate 38 positions.
The summit of said locking plate projection 9.4 is positioned at said groove bottom land and belongs to horizontal below.
Rail indentation amount limiting plate 38 in the head end of interior orbiting end plate 31 is provided with.The width of rail indentation amount limiting plate 38 is greater than the width of interior tread side plate 32 in said, and the width of interior tread side plate 32 is consistent with the width of interior flange of rail side plate 33.
On the interior orbiting end plate 31 near interior rail indentation amount limiting plate 38 positions, offer expanding unit installing hole 39, this expanding unit installing hole 39 style according to refrigerator when producing is installed required expanding unit.
When the present invention worked, sliding door locking plate 9 cooperated with the refrigerator sliding door self-locking body of outer rail tail end, makes refrigerator doors self-locking to put in place.
Refrigerator sliding door locking plate 9 is mounted in the tail end of rail 3 in the sliding door, and refrigerator sliding door self-locking body is mounted in the corresponding end of outer rail.When refrigerator doors was in unlatching, refrigerator sliding door locking plate 9 was in released state with the refrigerator sliding door with self-locking body, and the refrigerator sliding door is in extended state with the energy storage back-moving spring on the self-locking body, and self-locking body locking bar band the self-locking body slide block and is in the self-locking body locked groove.If the self-locking body locking bar slides to the junction of self-locking body locked groove and self-locking body chute, the energy storage back-moving spring will be with self-locking body locking bar and self-locking body slide block to get back to original position.
Locking plate lower side panel 9.2 antethecas in locking plate projection 9.4 summit the place aheads and the antetheca of locking plate projection 9.4 are combined to form horn mouth; When refrigerator sliding door locking plate 9 is pushed the refrigerator sliding door to self-locking body and when being in contact with it; Generally speaking, the antetheca of locking plate projection 9.4 extruding self-locking body locking bar, the self-locking body locking bar is because the horn mouth inclined-plane slowly slides to locking plate projection 9.4 summits; In the self-locking body slide rail; The self-locking body locking bar then slowly slides to the self-locking body chute by the self-locking body locked groove, and when the self-locking body locking bar slipped into the self-locking body chute fully, the self-locking body locking bar had also just slipped over locking plate projection 9.4 summits; Because it is sliding sliding backward always along the self-locking body chute with locking plate that the refrigerator sliding door in the effect of energy storage back-moving spring, self-locking body locking bar band, makes the refrigerator doors self-locking put in place.
Open the back again if the refrigerator doors self-locking puts in place; The self-locking body locking bar also is against on locking plate epipleural 9.1 rear walls at locking plate projection 9.4 summit rears; Pull out outer rail; The self-locking body locking bar slides to locking plate projection 9.4 gradually along locking plate projection 9.4 roots at locking plate projection 9.4 summit rears; The elastic force that refrigerator sliding door locking plate 9 in making on the rail overcomes the energy storage back-moving spring with self-locking body locking bar and self-locking body slide block slides to the junction of self-locking body locked groove and self-locking body chute, along with the tensile elongation change of energy storage back-moving spring greatly, the screen resilience that the self-locking body slide block receives is also big more.When the self-locking body locking bar was in the junction of self-locking body locked groove and self-locking body chute and gets into the self-locking body locked groove, the self-locking body locking bar had also just slipped over the summit of locking plate projection 9.4, and this moment, the refrigerator sliding door was in locking state with self-locking body.
