Detailed Implementation
[0018] The present invention will be further described below with reference to the embodiments and accompanying drawings.
[0019] refer to Figure 1 , Figure 2 , Figure 3 A splicing synchronous belt includes at least one belt body 1, which is made of rubber. A transmission structure 2 is provided at the bottom of the belt body 1. The transmission structure 2 includes two mating teeth 21 and a plurality of transmission teeth 22 disposed between the two mating teeth 21. Each mating tooth 21 and each transmission tooth 22 are equidistantly distributed along the length direction of the belt body 1. The two mating teeth 21 are located at both ends of the belt body 1. A mating groove 3 is provided on the bottom surface of the belt body 1 at the middle position of the mating teeth 21. The opening of the mating groove 3 penetrates the mating teeth 21. The mating teeth 21 are provided with first mating holes 4 penetrating their side walls.
[0020] The belt body 1 is detachably connected end to end via connector 5, forming a ring belt. Single or multiple belt bodies 1 can be spliced together to adjust the circumference of the synchronous belt for better applicability. Connector 5 is made of rubber, and both sides of connector 5 have mating parts 6, integrally formed with connector 5. The mating parts 6 have a second mating hole 7. The mating parts 6 are inserted into the mating groove 3, allowing them to engage with the corresponding mating teeth 21. The first mating hole 4 and the second mating hole 7 are coaxially aligned, and a mating rod 8 is inserted into both. A knob cover 9 is detachably connected to the end of the mating rod 8. Both sides of the mating teeth 21 have receiving grooves 10 for accommodating the knob cover 9. The receiving grooves 10 are coaxial with the first mating hole 4, and the inner diameter of the receiving grooves 10 is larger than the inner diameter of the first mating hole 4. The end of the connecting rod 8 that extends into the receiving groove 10 has a screw part 11, and the inner side wall of the knob cover 9 is provided with a nut part 12 that is threadedly connected to the screw part 11, so as to facilitate the disassembly and assembly of the knob cover 9 and the connecting rod 8.
[0021] The synchronous belt has a simple structure. The two ends of the belt body 1 are detachably connected by the connector 5. When the synchronous belt is partially damaged, the docking rod 8 can be taken out from the first docking hole 4 and the second docking hole 7 coaxially by operating the two corresponding knob covers 9 during disassembly and assembly. This allows the belt body 1 and the connector 5 to be separated so that the damaged belt body 1 can be removed and replaced. The disassembly and assembly operation is relatively convenient, reducing maintenance costs and improving maintenance efficiency and flexibility.
[0022] At least one alignment structure 13 is provided between the docking member 6 and the docking groove 3. The alignment structure 13 includes an alignment rib 131 and an alignment groove 132. The alignment rib 131 is inserted into the alignment groove 132 and is integrally formed on the top surface of the docking member 6. The alignment groove 132 is opened on the inner wall of the docking groove 3 to guide the alignment member to be installed in the correct position in the corresponding docking groove 3. The setting of the alignment rib 131 can improve the strength of the docking member 6 and effectively prevent the alignment member from breaking when it is stretched and deformed relative to the connecting member 5 during the use of the synchronous belt.
[0023] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
