Detailed Implementation

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] like Figures 1 to 8 As shown, a robot transmission connector includes a rectangular cylinder 1. A first connecting post 2 is fixedly connected to the back of the rectangular cylinder 1, and a second connecting post 3 is fixedly connected to the front of the rectangular cylinder 1. A first threaded cylinder 4 is fixedly connected to both the surface of the first connecting post 2 and the surface of the second connecting post 3. A threaded post 5 is threadedly connected to the inner wall of the first threaded cylinder 4. A connector head 6 is fixedly connected to one end of the threaded post 5, and a slot 7 is formed at the other end of the threaded post 5. Hollow blocks 8 are fixedly connected to both the front of the first connecting post 2 and the back of the second connecting post 3. A spring 9 is fixedly connected to the inner wall of the hollow block 8. A retaining plate 10 is fixedly connected to both ends of the spring 9. The inner wall of the slot 7 and the inner wall of the rectangular cylinder 1 are both in contact with the surface of the retaining plate 10. A first cylinder 11 is fitted onto the surface of the first connecting post 2 and the surface of the second connecting post 3. A column 12 is fixedly connected to the inner wall of the first cylinder 11 and the upper and lower sides of the clamping plate 10. A second cylinder 13 is fixedly connected to the surface of the first connecting post 2 and the surface of the second connecting post 3. A circular hole 14 is opened on the upper surface of the second cylinder 13. A second threaded cylinder 15 is fixedly connected to the inner wall of the circular hole 14. A first bolt 16 is threadedly connected to the inner wall of the second threaded cylinder 15. A first locking groove 17 is opened on the upper surface of the clamping plate 10. The inner wall of the first locking groove 17 fits against the surface of the first bolt 16. A rectangular hole 18 is opened on the front of the first threaded cylinder 4. A transparent scale 19 is fixedly connected to the inner wall of the rectangular hole 18.

[0030] The number of first locking grooves 17 on the card plate 10 is three, and the three first locking grooves 17 are equidistantly distributed along the length direction of the card plate 10. The maximum distance between the rectangular tube 1 and the end of the spring 9 is less than the length of the card plate 10.

[0031] It should be noted that, through the cooperation of the threaded column 5 and the first threaded cylinder 4, the user can adjust the length of the transmission connector according to different usage requirements by rotating the connector head 6, thereby improving the applicability of the transmission connector.

[0032] The rectangular tube 1 allows the clamping plate 10 to move only left and right. After the distance between the connector 6 and the first threaded tube 4 is adjusted to a suitable size, the clamping plate 10 is inserted into the slot 7 and the first bolt 16 is screwed into the first locking slot 17 to lock the threaded post 5, ensuring that the length of the transmission connector is stable and does not change during use. When the first bolt 16 is removed from the first locking slot 17, the clamping plate 10 can be automatically separated from the slot 7 by the pulling force of the spring 9. The first cylinder 11 is connected to the clamping plate 10 by the column 12. At this time, the user can move the clamping plate 10 through the first cylinder 11. The transparent scale 19 allows the user to intuitively judge the distance between the end of the threaded post 5 and the rectangular tube 1.

[0033] like Figures 1 to 11 As shown, the surface of the connector 6 is provided with a threaded hole 20, and the inner wall of the threaded hole 20 is threaded with a second bolt 21. The inner wall of the connector 6 is fitted with a flange 22, and the surface of the flange 22 is provided with a second locking groove 23. The inner wall of the second locking groove 23 is fitted with the surface of the second bolt 21. The upper surface of the flange 22 is fixedly connected with a third cylinder 24, and the bottom of the flange 22 is fixedly connected with a fourth cylinder 25. The surfaces of the third cylinder 24 and the fourth cylinder 25 are both fitted with the inner wall of the connector 6, and the bottom of the third cylinder 24 and the upper surface of the fourth cylinder 25 are both fitted with the surface of the second bolt 21.

[0034] Among them, a ring 26 is fixedly connected to the surface of the third cylinder 24, a positioning groove 27 is provided on the inner wall of the ring 26, a positioning block 28 is fitted on the inner wall of the positioning groove 27, and the bottom of the positioning block 28 is fixedly connected to the upper surface of the connector 6.

[0035] It should be noted that the engagement of the threaded hole 20, the second bolt 21, the second locking groove 23, the third cylinder 24, and the fourth cylinder 25 makes it easier to assemble and disassemble the connector 6 and the flange 22. This allows users to change the model of the flange 22 inside the connector 6 according to different usage requirements. At the same time, the engagement of the positioning block 28 and the positioning groove 27 allows users to quickly and accurately align the second locking groove 23 with the threaded hole 20, making it easier for users to screw the second bolt 21 into the second locking groove 23.

[0036] The working principle of this utility model is as follows: When it is necessary to adjust the length of the transmission connector, firstly, by rotating the first bolt 16, the first bolt 16 is separated from the first locking groove 17, and by the pulling force of the spring 9 on the clamping plate 10, the clamping plate 10 is separated from the clamping groove 7. Then, by rotating the connector 6, the distance between the connector 6 and the first threaded cylinder 4 can be changed by the cooperation of the first threaded cylinder 4 and the threaded column 5.

[0037] After the distance between the connector 6 and the first threaded cylinder 4 is adjusted to a suitable size, the first cylinder 11 is moved to insert the clamping plate 10 into the clamping groove 7, and the first bolt 16 is aligned with the first locking groove 17. Then, the first bolt 16 is screwed into the first locking groove 17 by rotating it. At this time, the first bolt 16 cannot be moved out of the first locking groove 17 due to the cooperation between the first bolt 16 and the second threaded cylinder 15. Then, the clamping plate 10 cannot be moved out of the clamping groove 7 due to the cooperation between the clamping plate 10 and the clamping groove 7. The threaded column 5 can be locked to ensure that the length of the transmission connector is stable and does not change during use.

[0038] When installing flange 22, first place flange 22 inside connector 6 and make positioning block 28 contact positioning groove 27. At this time, through the cooperation of positioning block 28 and positioning groove 27, the second locking groove 23 can be aligned with threaded hole 20. Then, screw the second bolt 21 into threaded hole 20 and make the surface of the second bolt 21 contact the inner wall of second locking groove 23. At this time, through the cooperation of second bolt 21, second locking groove 23, third cylinder 24 and fourth cylinder 25, flange 22 can be fixed inside connector 6.

[0039] When disassembling flange 22, flange 22 can be separated from connector 6 by unscrewing the second bolt 21 from the threaded hole 20.

[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
