Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, 2 and 3, the utility model provides a linkage sliding door, which comprises a door frame 1, a driving door 2, a driven door 3, a fixed door 4 and a linkage assembly, wherein the driving door 2 and the driven door 3 are respectively provided with a rolling connecting seat 4 and a roller 5 arranged on the rolling connecting seat, and the door frame 1 is provided with a roller groove 11 matched with the roller;

the linkage assembly comprises a driving wheel 6 and a driving strip 7 for driving the driving wheel, the driving wheel 6 is mounted on the passive door 3 through the rolling connecting seat 4, and the driving strip 7 is mounted on the rolling connecting seat 4 of the active door 2;

the driving wheel 6 comprises an outer wheel 61 and an inner wheel 62 driven by the driving bar, and the ratio of the diameter of the outer wheel 61 to the diameter of the inner wheel 62 is a preset diameter ratio. The outer wheel 61 rotates within the wheel groove.

Specifically, in order to adjust the height of the door body conveniently, the rolling connection seat 4 includes a seat body 41, a screw rod 42 arranged on the seat body, and a nut block 43 mounted on the screw rod, and the nut block 43 is provided with a rotating shaft 44 for mounting the roller 5 or the driving wheel 6. The nut block 43 is provided with a screw hole matched with the screw rod 42, and the screw rod 42 is rotated to enable the nut block 43 to move up and down along the screw rod 42, so that the door body is driven to move up and down.

In order to avoid opening holes in the door body, both sides of the driving door 2 and the driven door 3 are provided with protective edges 12, the rolling connecting seats are connected to the protective edges 12, and the protective edges 12 are provided with door body mounting grooves 13 for mounting the door body. The driving doors 2 are embedded in the corresponding door body installation grooves 13.

For convenience of description, the rolling connection seat 4 provided with the roller 5 is a first connection seat 4a, the first connection seats 4a are arranged at two ends of the top of the driving door 2, and two ends of the driving strip 7 are respectively connected with the first connection seats 4a at two sides;

the rolling connecting seat 4 provided with the driving wheel 6 is a second connecting seat 4b, and one end of the top of the driven door 3 is provided with the second connecting seat 4 b. The second connecting seat 4b is located between the two first connecting seats 4a on the driving door 2, so that the driving bar 7 can always drive the inner wheel 62 during the movement of the driving door 2.

In terms of controlling the moving relationship between the driving door 2 and the driven door 3, since the driving door 2 is generally the door body located at the outermost side, and the maximum stroke thereof is larger than that of the driven door, the diameter of the inner wheel 62 is smaller than that of the outer wheel 61, so as to reduce the moving distance of the driven door 3.

In order to prevent collision and seizure when the door is completely closed or opened, the active door 2 and the passive door 3 can be stopped at the same time.

Preferably, the ratio of the maximum stroke of the active door 2 to the maximum stroke of the passive door 3 is a stroke ratio, the outer wheel 61 and the roller 5 have the same diameter, and the stroke ratio is equal to the diameter ratio. If the present invention needs to be completely closed, the active door 2 needs to be moved for 2m, and the passive door 3 needs to be moved for 1m, the diameter of the outer wheel 61 is 2 times that of the inner wheel 62 when the diameters of the rollers and the outer wheel are the same.

Preferably, the driving bar 7 is a rubbing bar, and the inner wheel 62 is a concave wheel matched with the rubbing bar 7, and the concave wheel is in contact with the rubbing bar. The rubbing strip is preferably a rubber strip.

Preferably, the driving wheel 6 is of an integrated structure.

Referring to fig. 4, in a second embodiment of the present invention, unlike the first embodiment, the driving bar 7 is a rack, the inner wheel 6 is a gear, and the gear is engaged with the rack, so as to prevent a slip phenomenon between the driving bar and the inner wheel and stabilize a moving relationship between the driving door 2 and the driven door 3.

Through the principle that like poles repel each other, the inner wheel can be driven to rotate in a non-contact mode, and therefore noise in the door opening and closing process is greatly reduced.

In detail, the outer contour of the inner wheel 62 is polygonal to provide a plurality of planes for mounting magnetic blocks, and the magnetic block bar 71 is correspondingly provided with a corresponding number of magnetic blocks 73. If the outer contour of the inner wheel is a regular 12-sided polygon, the magnet strips are correspondingly provided with 12 magnets 73, so that the corresponding number of magnet strips can be conveniently and quickly installed according to the required stroke.

In the arrangement of the magnetic blocks, the polarities of the external magnetic poles of the two adjacent magnetic blocks are opposite, so that the stability of relative movement between the driving bar and the inner wheel 62 is improved, and the effect similar to gear engagement is realized.

Preferably, the magnetic block is a magnet.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the utility model.
