[0027] In the description of the present invention, it should be understood that descriptions involving orientation, such as orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0028] In the present invention, unless otherwise clearly defined, the words "set", "install", "connect" and the like should be understood in a broad sense, for example, they can be directly connected or indirectly connected through an intermediate medium; they can be fixedly connected or detachably connected or integrally formed; they can be mechanically connected; they can be the internal connection of two elements or the interaction relationship between two elements. Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0029] Reference Figures 1 to 3The lower positioning device of the embodiment of the present invention includes: a fixing member 100, on which a positioning groove 110 is provided; a swing arm 200, which is used to be rotatably connected to the door panel 11; a toggle member 300, which is used to be arranged on a first main body 12 located on one side of the door panel 11, and when the door panel 11 slides relative to the first main body 12, the toggle member 300 can drive one end of the swing arm 200 to enter the positioning groove 110; an elastic member 400, which is connected to the swing arm 200 and is used to drive the swing arm 200 to separate from the positioning groove 110.

[0030] When the door panel 11 slides relative to the first main body 12 until the door panel 11 is in a closed state or an open state, the swing arm 200 contacts the toggle member 300 and one end of the swing arm 200 enters the positioning groove 110, thereby stabilizing the relative position of the door panel 11. When the swing arm 200 leaves the fixing member 100, the swing arm 200 is reset under the action of the elastic member 400 so that the door panel 11 can slide freely. The above structure can assist in supporting the door panel 11, thereby preventing the sliding door or the linked door from tilting due to the deadweight or external force of the door panel 11, thereby ensuring the smoothness of opening and closing the door and the service life of the sliding door or the linked door.

[0031] See also Figure 3 , the position where the lower positioning device is set can stabilize the door panel 11 in the closed state. Before the door panel 11 moves to the closed state, the swing arm 200 moves away from the positioning groove 110 in the height direction under the action of the elastic member 400, so that the door panel 11 can slide freely relative to the first body 12. When the door panel 11 slides relative to the first body 12 until the door panel 11 is in the closed state, the toggle member 300 contacts the end of the swing arm 200 away from the positioning groove 110, thereby driving the end of the swing arm 200 close to the positioning groove 110 to enter the positioning groove 110, thereby limiting the position of the door panel 11, playing the role of auxiliary support of the door panel 11, and preventing the door panel 11 from moving relative to the first body 12. It should be noted that for the sliding door provided with the above-mentioned positioning device, the general sliding door includes a fixed door 20 and a movable door 30, the fixed door 20 is equivalent to the above-mentioned first body 12, and the movable door 30 is equivalent to the above-mentioned door panel 11. For the linkage door provided with the above-mentioned positioning device, a general linkage door includes a fixed door 20 and a plurality of movable doors 30, wherein the fixed door 20 is equivalent to the above-mentioned first main body 12 relative to the adjacent movable door 30; for two adjacent movable doors 30, one movable door 30 is equivalent to the above-mentioned door panel 11, and the other movable door 30 is equivalent to the above-mentioned first main body 12.

[0032] See also Figure 1 , Figure 2 and Figure 3In some embodiments of the present invention, the swing arm 200 is provided with a pivot member 201 for rotationally connecting to the door panel 11, and the swing arm 200 has a swing section 210 and a toggle section 220 respectively located on both sides of the pivot member 201, and the toggle member 300 can abut against the toggle section 220 to make the swing section 210 swing downward to enter the positioning groove 110. It can be understood that after the toggle member 300 is separated from the swing arm 200, under the action of the elastic member 400, the swing section 210 swings upward to avoid interference when the door panel 11 slides relative to the first body 12, and the lower end of the toggle section 220 is lower than the lower end of the swing section 210, and the door panel 11 can slide until the toggle member 300 contacts the toggle section 220, thereby driving the swing section 210 to enter the positioning groove 110 again.

[0033] See also Figure 1 , Figure 2 In some embodiments of the present invention, the elastic member 400 is a torsion spring passing through the pivot member 201, and the two ends of the torsion spring are respectively in contact with the door panel 11 and the swing arm 200 to drive the swing section 210 to swing upward to disengage from the positioning groove 110. The elastic member 400 is the above-mentioned torsion spring, which can simplify the structure of the lower positioning device and facilitate assembly and use.

[0034] See also Figure 1 , Figure 2 In some embodiments of the present invention, the lower surface of the toggle section 220 is provided with a guide slope 221, and the toggle member 300 can abut against the guide slope 221 when the door panel 11 slides relative to the first body 12, so as to drive the swing section 210 to swing downward. With the above structure, the toggle member 300 can be in contact with the toggle section 220 when the door panel 11 slides relative to the first body 12, without the need to operate the toggle member 300 separately.

[0035] See also Figure 1 , Figure 2 In some embodiments of the present invention, in order to further realize sliding guidance of the lower part of the door panel 11, the toggle member 300 includes a mounting bracket 310, and the mounting bracket 310 is connected to a connecting seat 320 extending along its side, and a roller 330 is provided on the connecting seat 320. The roller 330 is used to extend into the sliding groove at the lower end of the door panel 11 to enable the door panel 11 to slide back and forth relative to the first body 12.

It should be noted that by loosening the threaded fastener and moving the position of the side plug plate 311, the position of the roller 330 along the thickness direction of the door panel 11 can be adjusted, so as to adapt to door panels 11 of different thicknesses.

[0037] See also Figure 1 , Figure 2 In some embodiments of the present invention, the fixing member 100 includes a flat plate, the upper surface of which is concave downward to form a sinking cavity, which constitutes a positioning groove 110, and both ends of the flat plate are respectively provided with mounting holes 120 for bolts to pass through. It should be noted that the fixing member 100 is generally installed on the ground. During installation, a cavity for accommodating the positioning groove 110 is reserved on the ground, and then the fixing member 100 is fixed on the ground after passing the bolts through the mounting holes 120.

[0038] See also Figure 2 In some embodiments of the present invention, in order to prevent the door panel 11 from relative movement along its thickness direction, a downwardly protruding anti-slip protrusion 211 is provided at the end of the swing section 210, and the width dimension of the anti-slip protrusion 211 is consistent with the width dimension of the positioning groove 110.

[0039] See also Figure 4 and Figure 5 The present invention also discloses a linkage door, comprising: an upper crossbeam 10, a fixed door 20 and a plurality of movable doors 30 which are arranged on the upper crossbeam 10 and are arranged in parallel in sequence, and the above-mentioned lower positioning device is provided between the fixed door 20 and the adjacent movable door 30, and between the adjacent movable doors 30.
