Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-5 , the present invention provides a technical solution: a sliding door interlocking structure for an integrated container rack. The integrated container rack includes a door frame 1 and a safety door 2. A cavity 3 is opened inside the safety door 2. A transmission rod 4 is rotatably connected to the inner wall of the cavity 3. The end of the transmission rod 4 extends to the outside of the safety door 2, and a key slot 5 is opened at the end of the transmission rod 4. The outer surface of the transmission rod 4 is fixedly connected with a first gear 6 and a positioning ring respectively. A plurality of positioning grooves 7 are arranged in a circular array on the outer surface of the positioning ring. A control mechanism 8 and an interlocking mechanism 9 are also arranged on the inner wall of the cavity 3. A jack 10 that cooperates with the interlocking mechanism 9 is opened on the inner wall of the door frame 1.

[0025] The interlocking mechanism 9 includes a second gear 11, a winding wheel 12, two pulling ropes 13, two support plates 14, two springs 15, two baffles 16, two bolts 17 and two limit sleeves 18. The winding wheel 12 is fixedly connected to the surface of the second gear 11. The second gear 11 is rotatably connected to the inner wall of the cavity 3, and the first gear 6 and the second gear 11 are meshed with each other. The support plate 14 and the limit sleeve 18 are both fixedly connected to the inner wall of the cavity 3. A round hole is formed on the surface of the support plate 14. The spring 15 is fixedly connected to the surface of the support plate 14. The baffle 16 is fixedly connected to the end of the spring 15. The pulling rope 13 passes through the round hole and is fixedly connected between the winding wheel 12 and the baffle 16. The bolt 17 is fixedly connected to the surface of the baffle 16, and the bolt 17 is slidably connected to the limit sleeve 18. The end of the bolt 17 extends to the outside of the safety door 2, and the bolt 17 can be engaged with the jack 10. By providing the control mechanism 8 and the interlocking mechanism 9, inserting the key into the key slot 5 can conveniently rotate the transmission rod 4. The rotation of the transmission rod 4 can drive the rotation of the first gear 6. The rotation of the first gear 6 can drive the rotation of the second gear 11. The rotation of the second gear 11 can drive the rotation of the winding wheel 12. The rotation of the winding wheel 12 can wind up the pulling rope 13, so as to drive the movement of the baffle 16 and the bolt 17. After the spring 15 is compressed, the bolt 17 will slide into the limit sleeve 18. When the bolt 17 is away from the jack 10, the opening of the safety door 2 can be realized. In the present utility model, the pulling rope 13 can be wound up by rotating the key clockwise or counterclockwise when opening the safety door 2, so as to open the safety door 2, which is more convenient, effectively avoiding the situation of forgetting the rotation direction of the key, thus delaying the opening time of the safety door 2, or even rotating the key in the reverse direction to cause damage to the interlocking mechanism 9.

[0026] Through grooves 19 are formed on both sides of the limit sleeve 18. Limit posts 20 slidably connected to the through grooves 19 are fixedly connected to both sides of the bolt 17. By providing the through grooves 19 and the limit posts 20, the bolt 17 can be limited by the sliding of the limit posts 20 on the inner wall of the through groove, so as to avoid the bolt 17 detaching from the limit sleeve 18.

[0027] The control mechanism 8 includes an electromagnet 21, an end plate 22, a controller 23, a connecting rod 24, an iron plate 25, and a clamping joint 26. The electromagnet 21 and the end plate 22 are both fixedly connected to the inner wall of the cavity 3. The controller 23 is fixedly connected to the surface of the electromagnet 21 and is electrically connected to the electromagnet 21. The connecting rod 24 is slidably connected to the end plate 22. The iron plate 25 is fixedly connected to the upper end of the connecting rod 24. The clamping joint 26 is fixedly bonded to the lower end of the connecting rod 24 and can fit with the positioning groove 7. When closing the safety door 2, by using the spring 15 to apply a thrust to the baffle 16, the bolt 17 can be inserted into the jack 10, thereby realizing the closing of the safety door 2. And under the action of gravity, the iron plate 25, the connecting rod 24, and the clamping joint 26 will move downward. By using the clamping joint 26 to be stuck into the positioning groove 7, the positioning ring can be prevented from rotating, thereby preventing the transmission rod 4 from rotating, effectively avoiding the situation where the safety door 2 can be opened only with a key.

[0028] When opening the safety door 2, the controller 23 starts the electromagnet 21. By using the electromagnet 21 to adsorb the iron plate 25, the connecting rod 24 can be moved upward, so that the clamping joint 26 is separated from the positioning groove 7. At this time, the transmission rod 4 can be rotated only by inserting the key into the key jack 10 to open the safety door 2.

[0029] A base 27 is fixedly connected to the inner wall of the cavity 3. A docking groove 28 is provided on the surface of the base 27. A first contact 29 and a second contact 30 are provided on the inner wall of the docking groove 28. An alarm 31 is provided on the side of the base 27. A right-angle plate 32 is fixedly connected to the side of the iron plate 25. A conductive column 33 that can fit with the docking groove 28 is fixedly connected to the lower end of the right-angle plate 32. A missing plate 34 is fixedly connected to the outer surface of the transmission rod 4. A push switch 35 corresponding to the missing plate 34 is fixedly connected to the lower surface of the end plate 22. The right-angle plate 32 is made of insulating material.

[0030] The positive pole of the power supply is electrically connected to the push switch 35. The push switch 35 is electrically connected to the alarm 31. The alarm 31 is electrically connected to the first contact 29. The first contact 29 can be electrically connected to the conductive column 33. The conductive column 33 can be electrically connected to the second contact 30. The second contact 30 is electrically connected to the negative pole of the power supply. When the safety door 2 is closed, the iron plate 25, the connecting rod 24, and the clamping joint 26 will move downward under the action of gravity. The clamping joint 26 will be inserted into the positioning groove 7, thereby preventing the transmission rod 4 from rotating. And under the action of gravity, the conductive column 33 will also contact the first contact 29 and the second contact 30 in the docking groove 28. When a thief forcibly rotates the transmission rod 4, the bonding part between the clamping joint 26 and the connecting rod 24 will break. By rotating the transmission rod 4, the missing plate 34 can be driven to rotate. By rotating the missing plate 34, the push switch 35 can be touched, thereby realizing the connection of the alarm 31 circuit and turning on the alarm 31 to achieve the purpose of warning the thief and avoiding property losses.

[0031] When the safety door 2 is normally opened, the electromagnet 21 adsorbs the iron plate 25, which can drive the right-angle plate 32 to move upward, thereby driving the conductive column 33 to separate from the first contact 29 and the second contact 30. At this time, when the safety door 2 is opened by rotating the transmission rod 4 with the key, although the missing plate 34 can be driven to rotate and the pressing switch 35 can be touched, the circuit between the first contact 29 and the second contact 30 is not connected, so the alarm 31 will not be triggered.

[0032] Working principle: When the sliding door interlock structure of the cover integrated container rack is in use, if the safety door 2 needs to be opened, first, the electromagnet 21 needs to be turned on through the controller 23. The electromagnet 21 adsorbs the iron plate 25, which can drive the connecting rod 24 and the right-angle plate 32 to move upward, so that the clamping joint 26 can be disengaged from the positioning groove 7 and the conductive column 33 can be far away from the first contact 29 and the second contact 30. Then, insert the key into the keyhole 10 and rotate the key, which can drive the transmission rod 4 to rotate. The rotation of the transmission rod 4 can drive the first gear 6 to rotate. By the meshing transmission of the first gear 6 and the second gear 11, the winding wheel 12 can be driven to rotate. The rotation of the winding wheel 12 can wind the two pull ropes 13. After the pull ropes 13 are wound, the baffle 16 can be pulled by the pull ropes 13 to make the bolt 17 slide along the inner wall of the limit sleeve 18. When the bolt 17 is far away from the keyhole 10 of the door frame 1, the safety door 2 can be opened. In the present invention, when opening the safety door 2, the key can be rotated clockwise or counterclockwise to wind the pull ropes 13, so as to open the safety door 2, which is more convenient and effectively avoids the situation of forgetting the rotation direction of the key, delaying the opening time of the safety door 2, or even rotating the key in the reverse direction and causing damage to the interlock mechanism 9.

[0033] In the attached drawings of the disclosed embodiments of the present invention, only the structures related to the disclosed embodiments are involved. Other structures can refer to the general design. Without conflict, the same embodiment and different embodiments of the present invention can be combined with each other;

[0034] Finally, the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
