[0028] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0029] like Figure 1-3 As shown, the sliding door track used in the anti-falling installation structure in the technical solution disclosed herein includes a guide rail body 7, a guide rail groove 8 is opened inside the guide rail body 7, a strip groove 9 is opened on one side of the guide rail groove 8, and the width of the strip groove 9 is smaller than the width of the guide rail groove 8.

[0030] like Figure 1-7 As shown, a wooden sliding door anti-falling installation structure includes a connecting plate 1. A plurality of nail through holes can be opened on the connecting plate 1, so that the connecting plate 1 can be screwed to the wooden door by a plurality of screws. The connection stability between the connecting plate 1 and the wooden door can be improved by the plurality of screws, the connection area between the anti-falling installation structure and the wooden door can be enlarged, the concentrated stress of the wooden door can be reduced, and the breakage of the wooden door under the action of greater stress can be reduced.

[0031] like Figure 1-3As shown, the lower end of the connecting plate 1 is equipped with a connecting group 2, and the lower end of the connecting group 2 is equipped with an intermediate plate 3. The width of the intermediate plate 3 is smaller than the opening width of the strip slot 9, and the intermediate plate 3 can directly enter the interior of the guide groove 8 through the strip slot 9, or be directly taken out from the interior of the guide groove 8. Both sides of the intermediate plate 3 are equipped with adjustment brackets 4, and a round shaft 5 is fixedly connected to the adjustment bracket 4. The outer side of the round shaft 5 is rotatably connected to the pulley body 6. The adjustment bracket 4 is used to adjust the horizontal position of the round shaft 5. When the intermediate plate 3 drives the round shaft 5 to enter the interior of the guide groove 8, the position of the pulley body 6 is adjusted by adjusting the bracket 4, so that the pulley body 6 and the strip slot 9 are aligned. By staggering, the pulley body 6 can be stably assembled inside the guide rail body 7 to achieve the purpose of preventing it from falling off. When the structure of the device inside the guide rail groove 8 is damaged, the position of the pulley body 6 can be adjusted again by adjusting the bracket 4, so that the pulley body 6 is reset to the area opposite to the strip groove 9, and the middle plate 3 and the pulley body 6 can be directly taken out through the strip groove 9. The anti-falling installation structure can be relatively simple to install inside the sliding door track, and the anti-falling installation structure can be relatively simple to take out from the sliding door track, so that the anti-falling installation structure can be relatively simple to inspect and repair after the installation of the anti-falling installation structure is completed.

[0032] like Figure 3-4 As shown, the adjustment bracket 4 can be an electric adjustment mechanism or a manual adjustment structure, wherein the electric adjustment mechanism can be a manual adjustment structure, which is specifically that the adjustment bracket 4 includes a guide column 11 fixedly connected to one side of the middle plate 3, and the round shaft 5 is slidably connected to the outer side of the guide column 11, so that the round shaft 5 and the pulley body 6 can move horizontally, and the end of the round shaft 5 close to the connection between the middle plate 3 and the guide column 11 is fixedly connected to the back plate 13, and the first magnet 14 and the second magnet 15 are fixedly connected to the back plate 13, and the middle plate 3 is equipped with a manual switching group, and the manual switching group is equipped with a third magnet 17 and a fourth magnet 18. The manual switching group can drive the third magnet 17 and the fourth magnet 18 to move to adjust the position of the third magnet 17 and the fourth magnet 18. The first magnet 14 and the third magnet 17 magnetically repel each other. When the third magnet 17 and the first magnet When the first magnet 14 is relative to the fourth magnet 18, the back plate 13 and the circular shaft 5 can be pushed by the magnetic force between the third magnet 17 and the first magnet 14. The first magnet 14 and the fourth magnet 18 are magnetically attracted to each other. When the first magnet 14 and the fourth magnet 18 are relative to each other, the back plate 13 and the circular shaft 5 can be pulled by the magnetic force between the first magnet 14 and the fourth magnet 18. The second magnet 15 and the fourth magnet 18 are magnetically repelled from each other. When the second magnet 15 and the fourth magnet 18 are relative to each other, the back plate 13 and the circular shaft 5 can be pushed by the magnetic force between the second magnet 15 and the fourth magnet 18. The second magnet 15 and the third magnet 17 are magnetically attracted to each other. When the second magnet 15 and the third magnet 17 are relative to each other, the back plate 13 and the circular shaft 5 can be pulled by the magnetic force between the second magnet 15 and the third magnet 17, so that the pulley body 6 can be moved by magnetic force.

[0033] Among them, Figure 3-4 As shown, groove bodies 10 are opened on both sides of the middle plate 3, and the groove bodies 10 on both sides of the middle plate 3 are staggered. The guide columns 11 are fixedly connected to the inner walls of the groove bodies 10, so that the circular shaft 5 and the pulley body 6 can be retracted into the interior of the groove body 10, thereby effectively reducing the width of the combination of the middle plate 3, the circular shaft 5, and the pulley body 6.

[0034] Among them, Figure 4 and Figure 6 As shown, the manual switching group includes a turntable body 16 rotatably connected to the inner wall of the groove body 10 and located on the outside of the guide column 11, the third magnet 17 and the fourth magnet 18 are fixedly connected to the turntable body 16, the third magnet 17 and the fourth magnet 18 are symmetrically arranged with the center of the turntable body 16, and the center of the first magnet 14 and the second magnet 15 are symmetrically arranged. At this time, the positions of the third magnet 17 and the fourth magnet 18 can be adjusted by rotating the turntable body 16, so that the magnetic force is used to complete the movement of the pulley body 6.

[0035] More specifically, an elastic strip 19 is fixedly connected to the side wall of the groove body 10. The material of the elastic strip 19 can be spring steel or copper. The end of the elastic strip 19 away from the side wall of the groove body 10 is a movable end. The movable end of the elastic strip 19 is abutted against the peripheral side surface of the turntable body 16 under the action of the elastic force of the elastic strip 19, thereby increasing the friction force of the turntable body 16 when the turntable body 16 rotates, and the turntable body 16 can be positioned.

[0036] At the same time, the movable end of the elastic strip 19 can be bent into a V-shaped protrusion 20, and the peripheral side surface of the turntable body 16 is provided with a plurality of V-shaped grooves 28 in a circular array. The V-shaped protrusion 20 can be stuck into the interior of the V-shaped groove 28 under the elastic force of the elastic strip 19, thereby better locking the turntable body 16.

[0037] like Figure 4-5 As shown, in order to more stably lock the positions of the round shaft 5 and the pulley body 6, an inner cavity 21 is opened inside the guide column 11, and two opposite through grooves 24 are opened on the outer side of the inner cavity 21. Two slides 22 are slidably connected inside the inner cavity 21, and the two slides 22 are fixedly connected with limiting protrusions 23. The limiting protrusions 23 can extend to the outer side of the guide column 11 through the through grooves 24 and abut against the round shaft 5, thereby locking the round shaft 5.

[0038] Here, the sides of the two limiting protrusions 23 that are away from each other are inclined surfaces, and the two inclined surfaces are inclined toward the ends that are away from each other at one end close to the turntable body 16. At this time, when the inclined surfaces of the limiting protrusions 23 and the circular shaft 5 are against each other, the circular shaft 5 can be limited so that the circular shaft 5 cannot move freely toward the direction close to the turntable body 16.

[0039] In order to drive the slide plate 22 and the limiting protrusion 23 to move, the guide column 11 is also equipped with a position adjustment group connected to the two slide plates 22 near the turntable body 16, which is used to adjust the position of the slide plate 22. The position adjustment group in the technical solution is as follows: Figure 5 As shown, it includes a rotating rod 12 rotatably connected to the guide column 11 near the turntable body 16, and the rotating rod 12 is fixedly connected to the outer side of the rod body located inside the inner cavity 21 with two symmetrically arranged threaded parts 25, that is, the thread directions of the two threaded parts 25 are opposite, and the two threaded parts 25 are respectively threadedly connected to the two slides 22. When the rotating rod 12 rotates, the two limiting protrusions 23 can be driven to move in opposite directions through the two hexagonal cap heads 26, thereby synchronously adjusting the positions of the two limiting protrusions 23, so that the two limiting protrusions 23 can synchronously contact the circular shaft 5, and better position the circular shaft 5. One end of the rotating rod 12 is fixedly connected to the hexagonal cap head 26, and the hexagonal cap head 26 can be rotated by using an hexagonal wrench to drive the rotating rod 12 to rotate, and a circular groove 27 is provided on the outer side of the guide column 11, and the hexagonal cap head 26 is located inside the circular groove 27, thereby reducing the influence of the hexagonal cap head 26 on the sliding of the circular shaft 5.

[0040] Among them, Figure 2-3 As shown, the connection group 2 includes a sleeve body 29 rotatably connected to the lower end of the connecting plate 1, a hexagonal nut 31 is fixedly connected to the outer side of the sleeve body 29, a threaded rod 30 is threadedly connected to the inner side of the sleeve body 29, and the lower end of the threaded rod 30 is fixedly connected to the middle position of the upper side of the middle plate 3. At this time, when the middle plate 3 is installed into the guide rail groove 8, the connecting plate 1 is screwed to the wooden door, and then the sleeve body 29 and the threaded rod 30 are relative to each other, and the sleeve body 29 and the threaded rod 30 can be threadedly connected by rotating the hexagonal nut 31, thereby completing the connection between the wooden door and the middle plate 3 relatively simply.

[0041] The working principle of the present invention is:

[0042] During installation, the combination of the middle plate 3, the circular shaft 5 and the pulley body 6 is placed into the interior of the guide rail groove 8 through the strip groove 9, and then the turntable body 16 is rotated to make the first magnet 14 and the third magnet 17 face each other, and the second magnet 15 and the fourth magnet 18 face each other, and the second magnet 15 and the turntable body 16 are pushed by magnetic force, so that the pulley body 6 and the strip groove 9 are staggered, and then the hexagonal cap head 26 is rotated by an hexagonal wrench to drive the limiting protrusion 23 to move, so that the limiting protrusion 23 and the circular shaft 5 are abutted, and the circular shaft 5 and the pulley body 6 can be positioned. After the positioning is completed, the wooden door and the middle plate 3 can be connected together through the connecting group 2.

[0043] When the anti-falling installation structure is to be repaired or replaced, the wooden door and the middle plate 3 are separated by the connection group 2, and then the hexagonal cap head 26 is rotated to reset the limit protrusion 23, and the turntable body 16 is rotated to make the first magnet 14 and the fourth magnet 18 face each other, and the second magnet 15 and the third magnet 17 face each other, and the second magnet 15 and the turntable body 16 are pulled by magnetic force to reset the pulley body 6 to the area opposite to the strip notch 9, and the middle plate 3 and the pulley body 6 can be directly taken out through the strip notch 9;

[0044] In summary, the technical solution can adjust the width of the middle plate 3, the round shaft 5 and the pulley body 6 combination by arranging a movable round shaft 5 and a pulley body 6, so that the width of the middle plate 3, the round shaft 5 and the pulley body 6 combination can be adjusted to be larger than the opening width of the strip slot 9 or smaller than the opening width of the strip slot 9, thereby making it easier to install the anti-falling installation structure inside the sliding door track, and easier to remove the anti-falling installation structure from the sliding door track, and easier to inspect and disassemble the anti-falling installation structure after the installation is completed.

[0045] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
