The relative arrangement here can be arranged oppositely on the same vertical plane, or can be arranged relative to each other in space; the second sliding rail The side of 44 facing the second swing lever 42 has an inclined surface 440, and the inclined surface 440 gradually extends away from the first slide rail 20 along the door opening direction L1; it should be noted that the second slide rail 44 only needs to be locked by bolts. The installation can be completed by fixing it on the side wall of the frame 2.

The connecting piece 45 is connected to the second roller seat 321 of the pulley assembly 3; the connecting piece 45 has a guide portion 450 perpendicular to the first rail 20. In this embodiment, the guide part 450 is a short rod. A movable block 46 penetrates through the guide part 450 and is guided by the guide part 450 to be slidably disposed on the guide part 450.

The crimping element 6 is arranged in the frame 2; the crimping element 6 acts on the movable block 46 so that the movable block 46 is arranged on the first swing rod 41, the second swing rod 42 and the second slide rail 44 in sequence Move to reset. In this embodiment, the crimping member 6 includes a coil spring 61 and a first traction rope 62. The inner end of the coil spring 61 is fixed to the pulley assembly 3, and the outer end of the coil spring 61 is connected to the lower surface of the movable block 46 through the traction rope. Meet. As a result, the force of the coil spring 61 acts on the movable block 46 via the first traction rope 62, so that the movable block 46 keeps abutting against the first swing rod 41, the second swing rod 42 and the second swing rod during the opening and closing of the sliding door. Two slide rail 44.

As shown in Figure 2, when the user applies force to drive the door body 1 to move in the door opening direction L1, the connecting piece 45 connected to the second roller seat 321 moves with the door body 1, and the upper movable block 46 moves along the first swing rod 41 moves up, and then as shown in Figure 3, the movable block 46 moves over the shaft 47 and then moves along the second swing bar 42. With the inclination angle of the second swing bar 42, the door body 1 can automatically move toward the door opening direction under the action of gravity. L1 completes the movement of the remaining door opening, and the user does not need to exert any more force. As shown in Fig. 4, when the movable block 46 passes over the free end of the second swing rod 42, the movable block 46 moves and descends to the inclined surface 440 of the second slide rail 44. Moving along the inclined surface 440 of the second slide rail 44 causes the door body 1 to move in the door closing direction L2. Finally, as shown in Fig. 5, after the movable block 46 passes through the free end of the first swing rod 41, the door body 12 returns to the initial door closing position. The slanted surface 440 of the second swing bar 42 and the second slide rail 44 is moved by the action of the crimping member 6, and the door is moved by the inclination angle of the second swing bar 42 and the slanted surface 440 of the second slide rail 44. Body 1 realizes automatic switching under the action of gravity.

In actual use, the user's hand grips the handle on the door body 1 and moves in the direction of opening the door. It should be noted that the distance that the user only needs to pull is the distance that the movable block 46 slides on the first swing rod 41; Specifically, as shown in FIG. 2, when the door body 1 is pulled for displacement, the first wheel 310 and the second roller 320 slide along the first slide rail 20 (here the first and second rollers 310, 320 are always kept in the first Slide rail 20); and the connecting piece 45 in the door body 1 element connected to the second roller seat 321 drives the movable block 46 to also move in the door opening direction L1. At this time, the movable block 46 moves along the first A swing rod 41 moves. Since the movable block 46 and the guide portion 450 of the connecting member 45 slide relatively, the movable block 46 tilts and moves upward in the door opening direction L1 when the first swing rod 41 slides, so the user needs to apply force After pulling this distance, as shown in FIG. 3, the movable block 46 crosses the rotating shaft 47 and enters the second swing rod 42. The movable block 46 presses the second swing rod 42 downward due to the force of the crimping member 6. , The force of the gravity of the movable block 46 and the force of the crimping member 6 is greater than the force of the first elastic body 43, so the movable block 46 slides along the second swing rod 42 inclined obliquely downward in the direction of opening the door (it needs to be explained here) When moving in the door opening direction, the inner end of the coil spring 61 is connected to the shaft or other components of the first roller 310. When the first roller 310 rotates, the inner end is wound, so that the outer end continuously rotates and winds in , The first traction rope 62 connected to the outer end of the linkage is also wound around, and then pulls the movable block 46 to move downwards), therefore, the distance that the user exerts force is from the initial position of the movable block 46 to the pivotally connected first swing rod 41 The distance from the rotating shaft 47 of the second swing lever 42 can be released after passing over the rotating shaft 47, and the door body 1 can continue to move in the door opening direction without applying force;

As shown in Figure 4, the movable block 46 moves on the second swing bar 42 until the movable block 46 falls from the edge of the second swing bar 42 and falls on the second slide rail 44; at this time, the second swing bar 42 has been Without the gravity of the movable block 46 and the loading force of the coil spring 61, the torsion spring 43 is pushed up to restore the original natural state; the second swing rod 42 is tilted upwards, making the lower surface of the second swing rod 42 and the second The sliding rail 44 forms a distance 48 for the movable block 46 to pass through. The movable block 46 moves in the reverse direction through the inclined surface 440 of the second sliding rail 44, thereby driving the second roller 320 to move in the reverse direction, and the coil spring 61 is also reversed. When the rotation is loosened, the crimping force of the movable block 46 pulling down is gradually reduced; then, as shown in FIG. The first swing lever 41 returns to the original position.

The movable block 46 slides back and forth in sequence from the first swing rod 41, the second swing rod 42 and the second slide rail 44 to realize the functions of semi-automatic door opening and automatic door closing;

It should be noted that, in order to prevent excessive impact when the door is automatically closed, a buffer 7 is also provided in this embodiment. As shown in FIGS. 1 and 2, the buffer 7 is installed on the first roller seat 311; the buffer 7 7 includes a housing 71, a push rod 72 and a second elastic body (not shown in the figure), the second elastic body (not shown in the figure) and the push rod 72 are installed in the housing 71, and the first The two ends of the two elastic bodies (not shown in the figure) act on the inner wall of the housing and one end of the push rod 72 respectively; wherein, the buffer member 7 moves in the reverse direction with the pulley assembly 3 to drive the other of the push rod 72 One end abuts against the side wall of the frame 2.

Furthermore, if the door needs to be opened for a long time, the sliding door can be restricted to the open state. When in use, only a limit slot 8 is provided on the first slide rail 20 and/or the second slide rail 44, such as As shown in Figures 1 and 2, the limit slot 8 is used for the second roller 320 and/or the movable block 46 of the pulley assembly 3 to be placed in the limit, that is, a limit can be provided on the second slide rail 44 Position slot 8, and the limit slot 8 is located between the edge of the second swing rod 42 and the maximum door opening position, so that the door body 1 can be moved by hand, so that the movable block 46 enters the limit slot 8, and the movable block 46 is kept It is positioned in the limit slot 8 to keep the door open all the time; and the limit slot 8 is opened between the edge of the second swing lever 42 and the maximum opening position for semi-automatic opening and closing when it is not the limit slot 8. The function can be used normally. In this embodiment, the limiting groove 8 is a groove provided on the inclined surface 440 of the second slide rail 44, which can accommodate the movable block 46 and restrict the movement of the movable block 46.
