[0012] Preferably, a plurality of bumps are provided at the bottom of the protective pad, and a second cavity is opened inside the bumps, a first cavity is opened inside the protective pad, a through hole is opened between the first cavity and the second cavity, and the bumps are made of wear-resistant silicone material.

[0013] The beneficial effects of the present invention are:

[0014] The present invention provides a locking mechanism, and when the robot cables are docked, the first connecting ring and the second connecting ring can protect the connected parts, thereby preventing the connected parts of the cables from being exposed to the outside world and causing dust to adhere to the connected parts of the cables, thereby causing damage to the cable docking. During this period, when the first connecting ring and the second connecting ring overlap, the plug plate will be inserted into the interior of the slot and squeeze the baffle. After being squeezed, the baffle will slide to one side. At this time, the bottom of the baffle will contact with the guide plate. Since the cross section of the guide plate is trapezoidal, as the baffle continues to move, the guide plate will drive one end of the balance plate to deflect downward, and the other end of the balance plate will drive the locking plate to deflect upward, so that the top of the locking plate is pressed against the plug plate. When the latch is inserted into the socket, the baffle stops moving, and the squeezing force of the locking plate on the plugging plate increases as the moving distance of the baffle increases, thereby improving the connection effect between the first connecting ring and the second connecting ring through the locking mechanism, preventing the first connecting ring and the second connecting ring from slipping off, thereby affecting the protection of the docking portion between the two cables. When it is necessary to disassemble the first connecting ring and the second connecting ring, the latch is pressed into the inside of the connecting groove by pressing the latch. At the same time, the plugging plate slides outwards by the elastic force of the second spring. At this time, the squeezing force of the locking plate on the plugging plate is weakened. As the plugging plate continues to slide, the locking plate will move away from the plugging plate, thereby facilitating the disassembly of the first connecting ring and the second connecting ring.

[0015] The present invention provides a clamping mechanism and a fixing mechanism. When the robot cables are docked, the clamping mechanism can facilitate the clamping of the cables to prevent the cables from falling off during docking, thereby affecting the docking of the cables. During this period, the clamping plate will deflect to one side under the pressure of the cable, and the clamping plate will squeeze the buffer pad when deflecting. At this time, the gas inside the buffer pad will be transported to the inside of the cavity through the connecting pipe after being squeezed. The air pressure inside the cavity will increase due to the input of gas. At this time, the piston plate will drive the push rod to slide downward under the action of the air pressure, so that the bottom of the clamping plate will act on the surface of the cable. The cable is then clamped and fixed by the clamping plate, and the cooperation between the clamping mechanism and the fixing mechanism can improve the stability of the cable during docking, so as to improve the docking effect of the cable and prevent the cable from falling off during docking, thereby interfering with the docking of the cable. During this period, the surface of the cable can be protected by the protective pad, and the cable will squeeze the protective pad. At this time, the gas inside the first chamber will be transported to the inside of the second chamber through the through hole after being squeezed, and the protrusion will bulge due to the input of gas, so that the bulging protrusion can increase the friction between the cable and the protective pad, thereby facilitating the improvement of the stability of the cable docking.

DETAILED DESCRIPTION Example 1

[0026] Reference Figure 1-6 A cable docking assembly for a robot comprises two fixing sleeves 1 and two connecting sleeves 4. A plurality of connecting rods 5 are connected between the two fixing sleeves 1 by bolts. The two fixing sleeves 1 are fixedly connected to the two connecting sleeves 4. A pulling groove 7 is provided on the outer wall of the two fixing sleeves 1 away from the connecting sleeve 4, and a pulling ring 8 is slidably connected to the inner wall of the two pulling grooves 7. One side of one pulling ring 8 is connected to the first connecting ring 2 by bolts, and one side of the other pulling ring 8 is connected to the second connecting ring 3 by bolts. A locking mechanism 15 is provided between the first connecting ring 2 and the second connecting ring 3, and push blocks are provided on the outer walls of the first connecting ring 2 and the second connecting ring 3.

[0027] On the basis of the above, the locking mechanism 15 includes a baffle 20, an insert plate 16 and a locking plate 26, and a slot 12 is provided on one side of the first connecting ring 2, and a second spring 21 is connected between the inner wall of one side of the slot 12 and the baffle 20 by bolts, and the slot 12 and the insert plate 16 are adapted to each other, and a fixing slot 13 is provided at the bottom of the slot 12, and a third spring 25 is connected between the fixing slot 13 and the locking plate 26 by bolts, and the inner walls on both sides of the opposite sides of the fixing slot 13 are rotatably connected to the rotating shaft 24 through bearings, and a balance plate 23 is connected between the two rotating shafts 24 by bolts, and one side of the top of the balance plate 23 is connected to the guide plate 22 by bolts, and the cross-section of the guide plate 22 is trapezoidal, and a protrusion is provided on the other side of the top of the balance plate 23, and the top of the protrusion contacts the bottom of the locking plate 26, and the top of the locking plate 26 is provided with multiple protruding teeth 27.

[0028] On the basis of the above, a connecting groove 17 is provided on one side of the top of the plugboard 16, and a latch 19 is slidably connected to the inner wall of the connecting groove 17. A first spring 18 is connected between the bottom of the latch 19 and the connecting groove 17 by a bolt. A socket 14 is provided on one side of the inner wall of the top of the slot 12, and the socket 14 is adapted to the latch 19. When the robot cable is docked, the first connecting ring 2 and the second connecting ring 3 can protect the connection part to prevent the cable connection part from being exposed to the outside world and causing dust to adhere to the cable connection part, thereby damaging the cable docking. During this period, when the first connecting ring 2 and the second connecting ring 3 overlap, the plugboard 16 will be inserted into the interior of the slot 12 and squeeze the baffle 20. After being squeezed, the baffle 20 will slide to one side. At this time, the bottom of the baffle 20 will contact the guide plate 22. Since the cross section of the guide plate 22 is trapezoidal, as the baffle 20 continues to move, the guide plate 22 will drive one end of the balance plate 23 to deflect downward. The other end of the balance plate 23 drives the locking plate 26 to deflect upward, so that the top of the locking plate 26 is pressed against the bottom of the plug plate 16. When the latch 19 is embedded in the inside of the socket 14, the baffle 20 stops moving, and the squeezing force of the locking plate 26 on the plug plate 16 increases as the moving distance of the baffle 20 increases, thereby improving the connection effect between the first connecting ring 2 and the second connecting ring 3 through the locking mechanism 15, preventing the first connecting ring 2 and the second connecting ring 3 from slipping off, thereby The protection of the docking position between the two cables is affected. When the first connecting ring 2 and the second connecting ring 3 need to be disassembled, the pin 19 is pressed to the inside of the connecting groove 17. At the same time, the elastic force of the second spring 21 causes the plug plate 16 to slide outward. At this time, the squeezing force of the locking plate 26 on the plug plate 16 will be weakened. As the plug plate 16 continues to slide, the locking plate 26 will move away from the plug plate 16, thereby facilitating the disassembly of the first connecting ring 2 and the second connecting ring 3.
