[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0025] Referring to Figures 1-4 A worm gear reducer connecting structure, including the reducer main body 1, the inside of reducer main body 1 is inserted with drive shaft 2, and the surface of drive shaft 2 is welded with connecting mechanism 3, the surface of connecting mechanism 3 is threadedly connected with the one end of protection mechanism 4, the insertion of reducer main body 1 and drive shaft 2 can be conveniently shielded and protected by protection mechanism 4, and the other end of protection mechanism 4 is fixedly connected with mounting mechanism 5.

[0026] Further, referring to Figure 2 And Figure 3 It can be known that connecting mechanism 3 includes clamping block 31, the surface of drive shaft 2 is welded with clamping block 31, and the surface of clamping block 31 is welded with the one end of fixed sleeve rod 32, the fixed sleeve rod 32 is conveniently limited and sealed by clamping block 31 and reducer main body 1 and fixed sleeve rod 32 welding, the other end surface of fixed sleeve rod 32 is installed with rotating disc 33 through bearing, and the end surface of rotating disc 33 is fixedly connected with first screw sleeve 34, rotating disc 33 is installed on the surface of fixed sleeve rod 32 through bearing, so that rotating disc 33 drives first screw sleeve 34 to rotate on the surface of fixed sleeve rod 32.

[0027] Further, referring to Figure 2 And Figure 3 It can be known that protection mechanism 4 includes second screw sleeve 41, the surface of first screw sleeve 34 is threadedly provided with second screw sleeve 41, and the end of second screw sleeve 41 is connected with the one end of protection rubber sleeve 42, the insertion of reducer main body 1 and drive shaft 2 can be conveniently shielded and protected by protection rubber sleeve 42, and at the same time, the outer thread is formed on the surface of first screw sleeve 34, and the inner thread is formed on the inner wall of second screw sleeve 41, so that second screw sleeve 41 is threadedly connected with first screw sleeve 34.

[0028] Further, referring to Figure 2 And Figure 3It can be seen that the installation mechanism 5 includes a connecting ring 51, and the other end of the protective rubber sleeve 42 is fixedly connected to the surface of the connecting ring 51. Multiple sets of mounting blocks 52 are fixed at equal intervals on the side of the connecting ring 51. The multiple sets of mounting blocks 52 are threadedly connected to the reducer body 1 by mounting bolts 53. By passing the mounting bolts 53 through the mounting blocks 52 and threadedly connecting them to the reducer body 1, it is convenient to drive one end of the protective rubber sleeve 42 to install the connecting ring 51.

[0029] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the extrusion mechanism 6 includes a fixed ring 61, the surface of the rotating disk 33 is fixedly connected to the fixed ring 61, and the side of the fixed ring 61 is fixedly connected to the fixed block 62. The internal thread of the fixed block 62 is inserted with a push stud 63, and the end of the push stud 63 is connected to the extrusion block 64 through a bearing. The fixed block 62 can conveniently limit the action of the push stud 63, so that when the push stud 63 is rotated, the push stud 63 pushes the extrusion block 64 to press against the surface of the second threaded sleeve 41, which facilitates the extrusion and limiting of the first threaded sleeve 34 and the second threaded sleeve 41, preventing them from loosening and falling off.

[0030] Furthermore, refer to Figure 4 It can be seen that the cross-section of the extrusion block 64 is set to an arc shape, and the lower surface of the extrusion block 64 is provided with anti-slip texture. By setting the cross-section of the extrusion block 64 to an arc shape, the extrusion block 64 can be pressed against the surface of the second threaded sleeve 41.

By abutting the side of the extrusion block 64 against the surface of the rotating disk 33 and the fixed ring 61, the extrusion block 64 can be limited and guided, preventing the extrusion block 64 from rotating when the stud 63 is pushed to rotate.

[0031] Working principle: When the reducer body 1 is in use, according to the attached... Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4By threading the mounting bolt 53 through the connecting ring 51 to the surface of the reducer body 1, the connecting ring 51 can drive one end of the protective rubber sleeve 42 to connect with the reducer body 1. After the drive shaft 2 is inserted into the second threaded sleeve 41 and the protective rubber sleeve 42 and installed with the reducer body 1, the fixed sleeve rod 32 can drive the rotating disk 33 to be sleeved on the surface of the drive shaft 2, and the second threaded sleeve 41 is threadedly connected with the first threaded sleeve 34. At this time, rotating the push stud 63 can easily push the extrusion block 64 to press against the surface of the second threaded sleeve 41, which is convenient to limit the second threaded sleeve 41 to prevent loosening. The two sets of snap-fit ​​blocks 31 are snapped onto the surface of the drive shaft 2, so that the snap-fit ​​blocks 31 are in contact with the end of the fixed sleeve rod 32. The snap-fit ​​blocks 31 are welded and sealed between the drive shaft 2 and the fixed sleeve rod 32, which can seal and protect the connection between the reducer body 1 and the drive shaft 2.
