DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. It should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "setting" should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0022] Reference Figure 1-Figure 4 A guide rail self-locking mechanism for a sliding door comprises a guide rail 1, which is an I-shaped guide rail, and two slide seats 3 are slidably connected to the guide rail 1. The two slide seats 3 are welded with mounting seats 2 connected to the sliding door, and the bottom of the sliding door is mounted in the mounting seats 2 on the two slide seats 3. The slide seat 3 is provided with a locking component connected to the guide rail 1, and the locking component comprises a magnet bar 16 and a second magnet block 14. A slide groove 13 is opened on one side of the slide seat 3, and the second magnet block 14 is slidably connected in the slide groove 13. A magnet bar 16 is provided on one side of the guide rail 1, and the second magnet block 14 is adsorbed with the magnet bar 16 to lock the slide seat 3 at any position on the guide rail 1.

[0023] In the utility model, a push rod 5 is slidably connected to one side of the slide seat 3, and one end of the push rod 5 is fixed to the second magnet block 14, and a first magnet block 12 is bonded to the inner wall of one side of the slide groove 13. A driving component for moving the push rod 5 is provided on the slide seat 3, so that the second magnet block 14 is separated from the magnet bar 16, and then adsorbed with the first magnet block 12, so as to facilitate the free movement of the slide seat 3 on the guide rail 1. A tension spring 11 is sleeved on the circumferential outer wall of the push rod 5, and the two ends of the tension spring 11 are respectively fixed to the push rod 5 and the slide seat 3. The driving component includes an inclined block 7 and a touch rod 6. A limiting opening 9 is provided on one side of the slide seat 3, and a pressing block 10 is slidably connected in the limiting opening 9. The bottom of the pressing block 10 is fixed with an inclined block 7 by bolts. A touch rod 6 is welded to one side of the push rod 5, and the inclined block 7 contacts the touch rod 6. A spring 8 is welded inside the limiting opening 9, and the spring 8 is connected to the pressing block 1 0 is fixed, the pressing block 10 is stepped on and pressed downward by the foot, the pressing block 10 drives the inclined block 7 to move downward along the limit opening 9, the spring 8 is forced to shrink, and the inclined block 7 moves downward to squeeze the touch rod 6. After the touch rod 6 is squeezed, the push rod 5 begins to move outward, the tension spring 11 is forced to extend, and the push rod 5 moves outward to make the second magnet block 14 move outward along the slide groove 13 and separate from the magnet strip 16. When the second magnet block 14 moves to contact with the first magnet block 12, it stops. The first magnet block 12 and the second magnet block 14 are attracted to each other. At this time, the adsorption force between the two is greater than the tension of the tension spring 11, and the push rod 5 will not reset and remain fixed. Release the pressing block 10, and the spring 8 rebounds and resets to make the pressing block 10 drive the inclined block 7 to move upward and reset. Since the second magnet block 14 is separated from the magnet strip 16, the slide 3 can move freely along the guide rail 1.

[0024] In the utility model, a sliding opening 15 is opened on one side of the guide rail 1, and a magnet strip 16 is slidably connected to the inside of the sliding opening 15. A screw rod 17 is threadedly connected to one side of the guide rail 1 near both ends, and the screw rod 17 passes through the sliding opening 15 and is rotatably connected to the magnet strip 16. When it is necessary to stop locking the sliding door, the user can rotate the screw rods 17 at both ends, and the rotation of the screw rod 17 drives the magnet strip 16 to move. The magnet strip 16 moves inward along the sliding opening 15 and disengages from the second magnet block 14. After the second magnet block 14 is freed from the restraint, the lock on the slide seat 3 is released, and the sliding door can move freely.

[0025] In the utility model, support seats 4 are welded to the bottoms of both ends of the guide rail 1, and mounting holes are provided on the support seats 4.

[0026] Working principle: when in use, install the bottom of the sliding door in the mounting seat 2 on the two sliding seats 3. When the sliding door needs to be moved, step on the pressing block 10 with your foot and press it downward. The pressing block 10 drives the inclined block 7 to move downward along the limit opening 9, the spring 8 is forced to shrink, and the inclined block 7 moves downward to squeeze the touch rod 6. After the touch rod 6 is squeezed, the top rod 5 begins to move outward, the tension spring 11 is forced to extend, and the top rod 5 moves outward to make the second magnet block 14 move outward along the slide groove 13 and separate from the magnet strip 16. When the second magnet block 14 moves to contact with the first magnet block 12, it stops. The first magnet block 12 and the second magnet block 14 are attracted to each other. At this time, the adsorption force between the two is greater than the tension of the tension spring 11, and the top rod 5 will not reset and remain fixed. Release the pressing block 10, and the spring 8 rebounds and resets to make the pressing block 10 drive the inclined block 7 to move upward and reset. Since the second magnet block 14 is separated from the magnet strip 16, the sliding seat 3 can move freely along the guide rail 1.

[0027] When the position of the sliding door is determined, press the top rod 5 inward with your foot to separate the second magnet block 14 from the first magnet block 12, and then the tension spring 11 rebounds and resets to make the second magnet block 14 contact and adsorb with the magnet bar 16 again, and then the second magnet block 14 stabilizes the slide seat 3 as a whole at a certain position on the guide rail 1, so that the sliding door remains stable on the slide seat 3 and completes self-locking.

[0028] In this application, structures and connection relationships that are not described in detail are all prior arts, and their structures and principles are well-known technologies and will not be described in detail here.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
