[0025] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] Please refer to Figures 1 to 5As shown in the figure, an embodiment of the utility model provides a tail pull rod structure for a suspension door, which specifically includes a pull rod body 1. One end of the pull rod body 1 is provided with a pull rod head 2. One end of the pull rod body 1 far from the pull rod head 2 is provided with an adjusting rod 4. One end of the adjusting rod 4 far from the pull rod body 1 is provided with a pull rod base 3. An adjusting mechanism is arranged between the adjusting rod 4 and the pull rod base 3. The adjusting mechanism includes a groove 11 arranged in the middle of the opposite sides of the pull rod body 1 and the adjusting rod 4. Fixed blocks 12 are fixedly arranged at the closer ends of the inner sides of the two grooves 11. A bidirectional lead screw 9 is commonly screwed on the two fixed blocks 12. The two ends of the bidirectional lead screw 9 respectively extend towards the inner sides of the two grooves 11. A driving ring 13 for driving the bidirectional lead screw 9 to rotate is fixedly arranged on the outer side of the middle of the bidirectional lead screw 9. By arranging the adjusting mechanism, the simultaneous displacement of the pull rod body 1 and the adjusting rod 4 can be realized, and the adjusting speed is increased.
[0027] Please refer to Figures 1 to 5 As shown in the figure, the protection component includes a protection cylinder 5 fixedly arranged on the outer side of one end of the adjusting rod 4 close to the pull rod body 1. One end of the protection cylinder 5 far from the adjusting rod 4 is located outside the pull rod body 1. The protection cylinder 5 is slidably connected with the pull rod body 1. An opening 8 corresponding to the driving ring 13 is arranged at the top of the protection cylinder 5. A positioning plate 17 is inserted into the opening 8. Fixed grooves 15 are arranged at both ends of the inner side of the opening 8. One end of the positioning plate 17 is provided with a first insertion strip 18. One end of the positioning plate 17 far from the first insertion strip 18 is provided with an installation groove 22. A second insertion strip 19 is movably connected to the installation groove 22. A spring 21 is arranged between the second insertion strip 19 and the inner wall of the installation groove 22. A push block 20 is fixedly arranged at one end of the second insertion strip 19 close to the spring 21 at the top. A cover plate 6 with a cross-section larger than that of the positioning plate 17 located at the top of the protection cylinder 5 is arranged at the top of the positioning plate 17. The bottom of the periphery of the cover plate 6 is closely attached to the top of the protection cylinder 5. One end of the cover plate 6 close to the second insertion strip 19 is provided with a through groove 23 communicating with the installation groove 22. The upper end of the push block 20 extends to the top of the cover plate 6 through the through groove 23. The first insertion strip 18 and the second insertion strip 19 are respectively inserted and matched with the two fixed grooves 15. The setting of the protection component ensures that the adjusting mechanism is not eroded by the external environment, and it is convenient to disassemble and assemble without using tools.
[0028] Specifically in this embodiment, in order to realize the rotation of the bidirectional lead screw 9, slots 14 are evenly arranged around the outer side of the driving ring 13. One end of the cover plate 6 is fixedly provided with a driving plate 16 for being inserted into the slots 14. The bottom of the driving plate 16 is flush with the bottom of the cover plate 6. By arranging the driving plate 16 and the slots 14, the driving rotation of the bidirectional lead screw 9 can be realized without carrying a workpiece separately, which increases the convenience.
[0029] When in use, when it is necessary to adjust the distance between the pull rod body 1 and the adjusting rod 4, the second insert 19 is pushed by the push block 20. The second insert 19 compresses the spring 21. Then, one end of the second insert 19 disengages from a fixed slot 15. Then, one end of the positioning plate 17 is pulled out upward, and then the positioning plate 17 is pulled horizontally, so that the first insert 18 at the other end of the positioning plate 17 disengages from another fixed slot 15. Then, the driving plate 16 at one end of the cover plate 6 is inserted into the slot 14, and the cover plate 6 and the positioning plate 17 as a whole act as a handle to drive the driving plate 16. The driving plate 16 drives the bidirectional lead screw 9 to rotate through the driving ring 13, so that the pull rod body 1 and the adjusting rod 4 are displaced simultaneously to achieve adjustment.
[0030] Further, guide rods 7 are symmetrically and fixedly connected to both sides of the end of the adjusting rod 4 close to the pull rod body 1. Guide grooves 10 corresponding to the guide rods 7 are symmetrically arranged on both sides of the end of the pull rod body 1 close to the adjusting rod 4. The end of the guide rod 7 away from the adjusting rod 4 is movably connected to the guide groove 10. The arrangement of the guide rods 7 and the guide grooves 10 can further increase the stability of the pull rod body 1 and the adjusting rod 4, and the protective cylinder 5 can also be used for guiding, with high stability.
[0031] After the adjustment is completed, the first insert 18 is inserted into the fixed slot 15 at one end. Similarly, the push block 20 is pushed to hide the second insert 19. The positioning plate 17 is completely placed into the opening 8 until it is horizontal. At this time, the cover plate 6 fits against the top of the protective cylinder 5. Finally, the push block 20 is loosened, the spring 21 resets, and one end of the second insert 19 is inserted into another fixed slot 15 to complete the fixation.
[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
