The features mentioned above may cause synchronous hetero-directional linkage doors to have deficiencies as follows.

1. Since the transmission pulley base is mounted on the guiding track in a moving direction of the hanging pulley set, in order to ensure that there is no interference between the transmission pulley base and the hanging pulley set, a length of the hanging-pulley guiding track is required to be increased to provide a position for mounting the transmission pulley base.

a transmission pulley 3, provided on the snap-fit fixing part 11 within the upper guiding track 1, the transmission pulley 3 being wound with a transmission member 31. In the present embodiment, the transmission member 31 is a transmission belt. The transmission member 31 is connected with a fixing device 5, the fixing device 5 being used for fixing the door-leaf upper frame 6.

The transmission pulley set 3 is positioned out of a movement path of the hanging pulley set 2, and the hanging pulley set 2 the fixing device 5 are relatively stationary, so that the transmission pulley set 3 and the fixing device 5 are spatially separated from the hanging pulley set 2. The hanging pulley set 2 is separated from the transmission pulley set 3 in a longitudinal space within the upper guiding track 1 to avoid interference while also saving the overall mounting length of the upper guiding track 1.
The transmission pulley set 3 is provided in the upper guiding track 1, and the transmission member 31 is positioned above a moving plane of the hanging pulley set 2. The transmission member 31 is provided in an interior of the upper guiding track 1, which reduces contact with the dust in the environment, thereby reducing the amount of wear and tear of the transmission member 31.
A top of the upper guiding track 1 is provided with a snap-fit fixing part 11 and a bottom thereof is provided with a hanging pulley sliding track 12, in which the transmission pulley set 3 is detachably connected to the snap-fit fixing part 11, and the hanging pulley set 2 is slidably provided on the hanging pulley sliding track 12, so that the upper guiding track 1 is divided into an upper structure and a lower structure, which is used for connecting the hanging pulley set 2 and the transmission pulley set 3 respectively, so as to specifically achieve that the two components are spatially separated.
Specifically, the snap-fit fixing part 11 includes a snap-fit chamber 111 and a snap-fit bottom rib 112, in which the snap-fit bottom rib 112 is positioned on a bottom of the snap-fit chamber 111 and extended towards two sides of the snap-fit chamber 111 to an internal sidewall of the upper guiding track 1. A scalable connecting structure is formed on a top of the upper guiding track 1, which is firmly fixed by a snap fit or a screw.
The transmission pulley set 3 includes a transmission pulley base 32 and a horizontal transmission pulley 33. The transmission pulley base 32 is snap-fitted in the snap-fit chamber 111 and snap-fitted with the snap-fit bottom rib 112. The horizontal transmission pulley 33 is rotatably connected to the transmission pulley base 32. An end of the transmission pulley base 32 near the horizontal transmission pulley 33 is provided with a baffle plate 321 vertically connected to the transmission pulley base 32, which prevents friction and loss from collision of the transmission belt of the horizontal transmission pulley 33 during installation.
Further, a plane where the hanging pulley set 2 slides along the hanging pulley sliding track 12 is parallel to a plane where the transmission pulley set 3 is positioned; a preset gap is provided between a plane where a highest point of the hanging pulley set 2 slides along the hanging pulley sliding track 12 and the plane where the transmission pulley set 3 is positioned. It is ensured that the hanging pulley set and the transmission pulley set are separated longitudinally, in which they do not interfere with each other during the sliding process.
As an embodiment, the transmission pulley set 3 includes an expansion member 34 and a pushing member 35. The pushing member 35 acts on the expansion member 34, so that the expansion member 34 expands in its width direction and is locked, which is used for snap-fitting to the snap-fit chamber 111. The expansion member 34 is provided below the transmission pulley base 32. The transmission pulley base 32 is also provided with multiple threaded holes and a corresponding number of fixing members 322, so that the fixing member 322 may connect and fix the expansion member 34 to the transmission pulley base 32. In the present embodiment, the fixing member 322 is fixing screw. The expansion member 34 is provided with a squeezing part, and the expansion member 34 is an elastic element. The squeezing part is a countersunk hole, which is conical in shape. The amount of the countersunk hole is not limited. A corresponding number of conical screws are connected to the countersunk holes to achieve the squeezing deformation of the expansion member 34. After the expansion member 34 is expanded, it is squeezed to two sides of the snap-fit chamber 111 within the upper guiding track 1 to be fixed, so as to achieve the fixation between the transmission pulley base 32 and the upper guiding track 1. It prevents the fixing member 322 from directly contacting with the upper guiding track 1, prevents the deformation of the track and the destruction of the rigidity of its own structure caused by drilling holes on a top of the upper guiding track 1.
In the present embodiment, a distance-adjusting screw 41 is provided between the hanging box 4 and the hanging pulley set 2. A distance between the hanging box 4 and the hanging pulley set 2 is adjusted to control a distance between a door frame and the track. The adjustment is convenient. It is to be noted that, the distance-adjusting screw 41 may be replaced by other connecting parts that may adjust a distance, or may be replaced by connecting part that may fix a distance as long as it plays a role of connection, which is not compulsorily required.
A bottom of the hanging box 4 is provided with a first snap-fit rib 42 extending towards two sides. The first snap-fit rib 42 is snap-fitted in the first mounting slot 61 of the door-leaf upper frame 6. A mounting slot is provided between the two first snap-fit ribs 42, in which the mounting slot is provided with tightening screws. Tightening screws are provided with forces towards two sides for the first snap-fit rib 42, so that the hanging box 4 is snap-fitted and fixed with the first mounting slot 61, thereby driving the door leaf to slide.
The fixing device 5 includes a fixing block 51, an extension link 52 and a connecting block 53. The extension link 52 longitudinally connects the fixing block 51 to the connecting block 53, so that the fixing device 5 provided longitudinally saves the space in a horizontal direction, thereby reducing the mounting length of the upper guiding track 1.
The fixing block 51 is provided with a first through-hole 511 for the transmission member 31 to pass through and a first threaded hole 512 communicated with the first through-hole 511. A first fixing screw passes through the first threaded hole 512 to abut and fix the transmission member 31 to the first through-hole 511, in which two first through-holes 511 are provided on the fixing block 51, which may be used for fixing two ends of the transmission belt simultaneously, so that two ends of the transmission member is connected to form a ring belt. Since the fixing device 5 occupies a little horizontal space, it ensures that the door is aligned with the ends of the track, which does not influence the sliding range of the door leaf. The fixing block 51 is fixed with the transmission member 31, so as to achieve the hetero-directional synchronization of the linkage door.
A bottom of the connecting block 53 is snap-fitted with the second mounting slot 62 of the door-leaf upper frame 6. The connecting block 53 is provided with a second threaded hole 531 and a third fixing slot 532. A second fixing screw passes through the second threaded hole 531 to press against the connecting block 53 to the second mounting slot 62. A third fixing screw passes through the third fixing slot 532 to fix the connecting block 53 to the second mounting slot 62. The third fixing screw is slightly inclined and snap-fitted with a protruding rib within the second mounting slot 62, so as to firmly fix the fixing device 5 with the door-leaf upper frame 6, thereby driving the transmission member 31 to slide, so that the door slides. The amount of the second threaded hole 531 and the third fixing slot 532 is not limited, which may be determined based on the weight of the door body and actual situations.
Two second mounting slot 62 is provided in the door-leaf upper frame 6, in which they are provided on two sides of the first mounting slot 61 respectively. A door slot is provided on a lower part of the door-leaf upper frame 6, used for snap-fitting with the door body.
The principles and mounting steps of the present disclosure are as follows.
An upper guiding track 1 with appropriate length is chosen. The transmission pulley bases 32 are snap-fitted in the snap-fit chambers 111 on two ends of the snap-fit fixing part 11 within the upper guiding track 1. Then, the pushing member 35 acts on the expansion member 34 to firmly fix the transmission pulley base 32 with the snap-fit fixing part 11. Four hanging boxes 4 are adopted to fix on top edges of two doors. Each hanging box 4 is connected with a hanging pulley set 2 by the distance-adjusting screw 41. A fixing member 5 is fixed with the door-leaf upper frame 6 fixed by two hanging boxes 4 positioned between two doors. A transmission belt is wound around the horizontal transmission pulleys 33 on the two transmission pulley bases 32, and two ends of the transmission belt are fixed on the fixing block 51 of one fixing device 5. At this moment, the hanging pulley set 2 is slidably provided in the hanging pulley sliding track 12 within the upper guiding track 1. The fixing blocks 51 of two fixing devices 5 are connected to the transmission belt of different sides. Thus, when one door is pushed, the door being pushed simultaneously drives the hanging pulley set 2 and the fixing device 5 to displace along the upper guiding track 1, and the transmission belt is rotated under the force. The other fixing device 5 slides driven by the rotation of the transmission belt, so that another door is pushed. So far, the function of the synchronous hetero-directional linkage door is achieved.
In summary, the mounting mechanism for a synchronous hetero-directional linkage door provided in the present disclosure has technical effects as follows.

1. The transmission member 31 is concealed in an interior of the upper guiding track 1, and the entire door body is simple and beautiful.
2. The transmission member 31 is concealed in an interior of the upper guiding track 1, whose contact with dust and debris in the environment becomes less, and the time for dust to corrode the transmission belt is greatly extended; in addition, due to the dust attached to the transmission belt, the amount of wear and tear of the transmission pulley is also greatly increased when the transmission belt is moving.
3. The transmission pulley base 32 is mounted above a moving direction of the hanging pulley set 2, in which the transmission pulley base 32 and the hanging pulley set 2 do not interfere with each other, so there is no need for increasing a length of the upper guiding track 1 to provide a position for mounting the transmission pulley base 32.
4. By providing an expansion member 34, the transmission pulley set 3 may be fixed in the upper guiding track 1 without damaging the upper guiding track 1.

The technical means disclosed in the solution of the present disclosure are not limited to those disclosed in the embodiments mentioned above but also include technical solutions consisting of any combination of the above technical features; it should be noted that for those of ordinary skill in the art, a plurality of improvements and modifications may be made without departing from the principles of the present disclosure; and these improvements and modifications are also considered to be within the scope of protection of the present disclosure.
