[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as generally understood by a person skilled in the art to which this application pertains. The terms used in the description of this application are used merely to describe specific embodiments and are not intended to limit this application.

[0037] As illustrated in FIGS. 1 to 6, an embodiment of the present application discloses a synchronous reverse interlocking door mounting mechanism comprising an upper guide rail (1), a hanging sliding roller set (2), and a power transmission wheel set (3), wherein

[0038] The interior of the upper guide rail (1) is divided into upper and lower structures.

[0039] The above hanging sliding roller set (2) is for connecting the upper frame (6) of the door, and

[0040] The above hanging sliding roller set (2) is slidably installed above the hanging wheel sliding rail (12) within the upper guide rail (1), and the hanging sliding roller set (2) includes several sets of sliding rollers, and a recess (21) that slides along the hanging wheel sliding rail (12) is installed on the rolling surface of the sliding roller, and the sliding process is smooth and stable and does not easily deviate from the upper guide rail (1), and a hanging box (4) is connected to the hanging sliding roller set (2), and the hanging box (4) is fixed to the upper frame (6) of the door;

[0041] The above power transmission wheel set (3) is installed in a snap fixing part (11) within an upper guide rail (1), and a power transmission member (31) is surrounded by the power transmission wheel set (3), and in this embodiment, the power transmission member (31) is a conveyor belt, and a cable fixing device (5) is connected to the power transmission member (31), and the cable fixing device (5) is fixed to the upper frame (6) of the door;

[0042] Here, the power transmission wheel set (3) is located outside the movement path of the hanging sliding roller set (2), and the position between the hanging sliding roller set (2) and the cable fixing device (5) is relatively fixed so that both the power transmission wheel set (3) and the cable fixing device (5) are spatially offset from the hanging sliding roller set (2). Since the hanging sliding roller set (2) and the power transmission wheel set (3) are positioned offset in the vertical space within the upper guide rail (1), interference is prevented, and at the same time, the overall mounting height of the upper guide rail (1) can be reduced.

[0043] The above power transmission wheel set (3) is installed within the upper guide rail (1), and the power transmission member (31) is located above the moving surface of the hanging sliding roller set (2). Since the power transmission member (31) is installed inside the upper guide rail (1), contact with dust in the environment is reduced, thereby reducing the amount of wear on the power transmission member (31).

[0044] A snap fixing part (11) located at the top and a hanging wheel sliding rail (12) located at the bottom are installed within the upper guide rail (1), and the power transmission wheel set (3) is detachably connected to the snap fixing part (11), and the hanging sliding roller set (2) is slidably installed on the hanging wheel sliding rail (12). By dividing the upper guide rail (1) into upper and lower structures and connecting the hanging sliding roller set (2) and the power transmission wheel set (3) respectively, a specific spatial misalignment effect between the two can be obtained.

[0045] Specifically, the snap fixing part (11) includes a snap cavity (111) and a snap bottom edge (112), the snap bottom edge (112) is located at the bottom of the snap cavity (111) and extends toward both sides of the snap cavity (111) to the inner wall of the upper guide rail (1), and forms an expandable connection structure on the top of the upper guide rail (1) so as to be stably fixed via a snap or screw.

[0046] The above power transmission wheel set (3) includes a power transmission wheel seat (32) and a horizontal power transmission wheel (33). The power transmission wheel seat (32) is snapped into the snap cavity (111) of the snap fixing part (11) and snapped to the snap bottom edge (112). The horizontal power transmission wheel (33) is rotatably connected to the power transmission wheel seat (32). A blocking plate (321) is installed at one end of the power transmission wheel seat (32) near the horizontal power transmission wheel (33) and is vertically connected to the power transmission wheel seat (32) to prevent wear and damage caused by a collision of the conveyor belt on the horizontal power transmission wheel (33) when mounted.

[0047] Additionally, the surface on which the hanging sliding roller set (2) slides along the hanging wheel sliding rail (12) is parallel to the surface on which the power transmission wheel set (3) is located, and since there is a gap between the surface on which the highest point of the hanging sliding roller set (2) slides along the hanging wheel sliding rail (12) and the surface on which the power transmission member (31) is located, the hanging sliding roller set (2) and the power transmission wheel set (3) are offset in the vertical direction to ensure that they do not interfere with each other during the sliding process.

[0048] In one embodiment, the power transmission wheel set (3) includes an expansion member (34) and a push member (35), and the push member (35) acts on the expansion member (34) to expand the expansion member (34) in its width direction and lock it so that it snaps into the snap cavity (111). The expansion member is installed below the power transmission wheel seat (32), and the power transmission wheel seat (32) is further provided with a plurality of screw holes and a corresponding number of fixing members (322), and the expansion member (34) and the power transmission wheel seat (32) can be connected and fixed through the fixing members (322). In this embodiment, the fixing member (322) is a fixing screw, and a compression part is installed in the expansion member (34). The expansion member is an elastic element, and the compression part is a counterbore. The counterbore is a conical hole. The number of counterbores is not limited. The expansion member is compressed and deformed by connecting through a conical screw corresponding to the number of counterbores. After expansion, the expansion member (34) is compressed and fixed to both sides of the snap cavity (111) within the upper guide rail (1), thereby achieving a fixing effect between the power transmission wheel seat (32) and the upper guide rail (1). Through this, the fixing member (322) is prevented from coming into direct contact with the upper guide rail (1), thereby preventing the rail from being deformed and its structural rigidity destroyed by drilling a hole in the upper guide rail (1).

[0049] In this embodiment, a pitch adjustment screw (41) is installed between the hanging box (4) and the hanging sliding roller set (2), and the distance between the door frame and the rail can be controlled by adjusting the gap between the hanging box (4) and the hanging sliding roller set (2), and the adjustment is convenient. It should be noted that the pitch adjustment screw (41) can be replaced with another distance adjustment connector or a fixed distance connector, and it is not mandatory to provide only the connection function.

[0050] A first snap edge (42) extending to both sides is installed at the bottom of the hanging box (4), and the first snap edge (42) is snapped into a first mounting groove (61) of the upper frame (6) of the door. A mounting groove is installed between the two first snap edges (42), and a tightening screw is installed within the mounting groove. By applying force toward both sides to the first snap edge (42) through the tightening screw, the hanging box (4) and the first mounting groove (61) are snapped and fixed, causing the door to slide.

[0051] The above cable fixing device (5) includes a cable fixing block (51), an extension rod (52), and a connecting block (53), and the extension rod (52) is connected between the cable fixing block (51) and the connecting block (53) in a vertical direction, thereby saving horizontal space and reducing the mounting length of the upper guide rail (1) by the cable fixing device (5) installed in a vertical direction.

[0052] In the above cable fixing block (51), a first through hole (511) through which the power transmission member (31) passes and a first screw hole (512) communicating with the first through hole (511) are formed, and the first fixing screw passes through the first screw hole (512) to securely fix the power transmission member (31) to the first through hole (511). Here, there are two first through holes (511) installed in the cable fixing block (51), and both ends of the conveyor belt can be simultaneously fixed so that both ends of the conveyor belt are connected to form an infinite belt. The cable fixing device (5) can occupy less horizontal space so that the door and the rail end maintain the same height, thus not affecting the sliding range of the door, and the cable fixing block (51) can be fixed to the power transmission member (31) so that the interlocking door can achieve reverse synchronization.

[0053] The lower end of the connecting block (53) is snapped into the second mounting groove (62) of the upper frame (6) of the door, and the connecting block (53) is provided with a second screw hole (531) and a third fixing groove (532). The second fixing screw passes through the second screw hole (531) to press the connecting block (53) against the second mounting groove (62), and the third fixing screw passes through the third fixing groove (532) to fix the connecting block (53) to the second mounting groove (62). The third fixing screw is slightly tilted and snaps into the ridge within the second mounting groove (62) to firmly fix the cable fixing device (5) and the upper frame (6) of the door, thereby allowing the power transmission member (31) to slide. Here, the number of the second screw hole (531) and the third fixing groove (532) is not limited and can be selected according to the weight of the door body and actual conditions.

[0054] In the upper frame (6) of the door, two second mounting grooves (62) are installed, each installed on both sides of the first mounting groove (61), and a door slot for snapping the door body is installed on the upper side of the upper frame (6).

[0055] The mounting steps and principles of the present application are as follows.

[0056] Select an upper guide rail (1) of appropriate length, and after snapping one power transmission wheel seat (32) into each of the snap cavities (111) at both ends of the snap fixing part (11) within the upper guide rail (1), apply the push member (35) to the expansion member (34) to stably fix the power transmission wheel seat (32) and the snap fixing part (11); select four hanging boxes (4) and fix them to the upper edges of each of the two doors, and each hanging box (4) is connected to one hanging sliding roller set (2) through a pitch adjustment screw (41); and a cable fixing device (5) is fixed to the upper door frame (6) fixed to the two hanging boxes (4) located between the two doors; A conveyor belt is wound around a horizontal power transmission wheel (33) on two power transmission wheel seats (32), and both ends of the conveyor belt are fixed to a cable fixing block (51) of one of the cable fixing devices (5). At this time, the hanging sliding roller set (2) is installed to slide on the hanging wheel sliding rail (12) within the upper guide rail (1), and the cable fixing blocks (51) of the two cable fixing devices (5) are each connected to the conveyor belts on different sides. Thus, when one of the doors is pushed, the pushed door pushes the hanging sliding roller set (2) and the cable fixing device (5) simultaneously to move along the upper guide rail (1), and the conveyor belt rotates under force, and the other cable fixing device (5) slides due to the rotation of the conveyor belt, causing the other door to be pushed, thereby obtaining the effect of a synchronous reverse interlocking door.

[0057] In summary, the synchronous reverse interlocking door mounting mechanism provided in this application has the following technical effects.

[0058] 1) The power transmission member (31) is hidden inside the upper guide rail (1), so the door body is overall simple and beautiful.

[0059] 2) The power transmission member (31) is hidden inside the upper guide rail (1), so contact with dust and foreign matter in the environment is reduced, which greatly increases the time the conveyor belt can withstand dust corrosion, and the amount of wear caused by dust attached to the conveyor belt wearing down the power transmission wheel when the conveyor belt moves is also greatly reduced.

[0060] 3) The power transmission wheel seat (32) is mounted above the direction of movement of the hanging sliding roller set (2), so that there is no interference between the power transmission wheel seat (32) and the hanging sliding roller set (2), and the mounting position of the power transmission wheel seat (32) is provided without the need to extend the length of the upper guide rail.

[0061] 4) An expansion member (34) is installed so that the power transmission wheel set is fixed within the upper guide rail without damaging the upper guide rail (1).

[0062] The means for solving the problem disclosed in the solution of this application is not limited to the means for solving the problem disclosed in the above embodiments, but also includes means for solving the problem composed of any combination of the above technical features. Those skilled in the art should note that various improvements and modifications are possible within the scope of the principles of this application, and that such improvements and modifications are also considered to be within the scope of protection of this application.
