[0014] In actual design, the upper screw 41 and the lower screw 42 are both straight rods with threads in the middle and no threads at both ends, wherein:

[0015] One end of the upper lead screw 41 is rotatably mounted on the upper fixed seat 11 through a bearing (not shown in the figure), and the other end of the upper lead screw 41 is rotatably penetrated through the upper support seat 21 through a bearing (not shown in the figure), and the upper lead screw 41 is movably screwed with the upper buckle 51;

[0016] One end of the lower lead screw 42 is rotatably mounted on the lower fixed seat 12 via a bearing (not shown in the figure), and the other end of the lower lead screw 42 is rotatably passed through the lower support seat 22 via a bearing (not shown in the figure). The lower lead screw 42 is movably screwed to the lower buckle 52.

[0017] like Figure 1 , Figures 3 to 5The upper driven pulley 61 and the lower driven pulley 62 are respectively located at the upper and lower parts of the support groove, and the upper driven pulley 61 and the lower driven pulley 62 are arranged relative to the support groove, that is, the upper driven pulley 61 and the lower driven pulley 62 are on the same vertical line as the axis of the support groove. Furthermore, the wheel diameter of the upper driven pulley 61 and the lower driven pulley 62 is the same, the wheel diameter of the driving pulley 63 is larger than the wheel diameter of the upper driven pulley 61 and the lower driven pulley 62, and the length of the belt 64 connected between the upper driven pulley 61 and the driving pulley 63 is equal to the length of the belt 64 connected between the lower driven pulley 62 and the driving pulley 63.

[0018] like Figure 1 , Figures 3 to 5 The driving pulley 63 is rotatably mounted on the lower support seat 22 , and the driving pulley 63 is coaxially arranged with the optical bar 30 , that is, the axis of the driving pulley 63 is arranged opposite to the axis of the optical bar 30 .

[0019] like Figure 1 A crank 65 is installed on the driving pulley 63, and the driving pulley 63 rotates under the drive of the crank 65.

[0020] like Figure 1 , Figures 3 to 5 , the fixing slot, the clamping slot and the supporting slot are arranged opposite to each other in the horizontal direction, that is, the fixing slot, the clamping slot and the supporting slot are arranged coaxially, wherein:

[0021] A semicircular upper fixing groove 110 is provided at the bottom of the upper fixing seat 11, and a semicircular lower fixing groove 120 is provided at the top of the lower fixing seat 12.

[0023] A semicircular upper clamping groove 511 is provided at the bottom of the upper clamping buckle 51 , and a semicircular lower clamping groove 521 is provided at the top of the lower clamping buckle 52 . The upper clamping groove 511 and the lower clamping groove 521 facing each other form a clamping groove together.

[0024] Furthermore, the diameters of the clamping groove and the fixing groove are matched with the diameter of the bellows so as to fix the bellows, and the diameter of the supporting groove should be slightly larger than the diameter of the bellows so that the bellows can perform translational movement under the support of the supporting groove.

[0025] In the present invention, the design of the clamping groove and the fixing groove can make the surrounding of the corrugated pipe evenly stressed, thereby ensuring that the corrugated pipe will not be pulled and damaged during the docking process.

[0026] like Figure 2The upper buckle 51 of the docking buckle mechanism 50 includes an annular upper buckle portion 510, which is provided with an upper slot 511 downwardly, and an upper connecting block 514 protrudes from the top of the upper buckle portion 510. The upper connecting block 514 is provided with an upper screw hole 515 for movably screwing with the upper lead screw 41. The upper buckle portion 510 is connected to the upper connecting portion 513 through an upper connecting handle 512, and the upper connecting portion 513 is provided with a light rod hole 53.

[0027] like Figure 2 The lower buckle 52 of the docking buckle mechanism 50 includes an annular lower buckle portion 520, and the lower buckle portion 520 is provided with a lower slot 521 upwardly, and a lower connecting block 524 is protruding from the bottom of the lower buckle portion 520, and a lower screw hole 525 for movably screwing with the lower lead screw 42 is provided on the lower connecting block 524, and the lower buckle portion 520 is connected to the lower connecting portion 523 through the lower connecting handle 522, and the lower connecting portion 523 is provided with a light rod hole 53, and the light rod hole 53 on the lower connecting portion 523 is relatively connected to the light rod hole 53 on the upper connecting portion 513, so as to be movably penetrated on the light rod 30.

[0028] like Figure 1 The connection mode between the upper and lower fixing seats 11, 12 and the optical bar 30, as well as the connection mode between the upper and lower supporting seats 21, 22 and the optical bar 30, can adopt the connection mode of the upper and lower connecting parts 513, 523 overlapping and movably penetrating the optical bar 30 similar to the upper and lower buckles 51, 52, so please refer to Figure 4 For your understanding, I will not elaborate on it here.

[0029] like Figure 2 A sub-pin seat 54 is installed on the upper buckle part 510 of the upper buckle 51, and a female pin seat 55 is installed on the lower buckle part 520 of the lower buckle 52, wherein: when the upper buckle 51 is buckled on the lower buckle 52, the sub-pin seat 54 and the female pin seat 55 are arranged opposite to each other to insert a pin 56 together to lock the upper buckle 51 on the lower buckle 52.

[0030] like Figure 1 , Figures 3 to 5 A sub-pin seat 13 is installed on the upper fixed seat 11, and a female pin seat 14 is installed on the lower fixed seat 12, wherein: when the upper fixed seat 11 is buckled on the lower fixed seat 12, the sub-pin seat 13 and the female pin seat 14 are arranged relatively to insert a pin 15 together to lock the upper fixed seat 11 on the lower fixed seat 12.

[0031] Of course, in actual implementation, the upper support seat 21 and the lower support seat 22 can also be installed with the male and female pin seats in the same manner as the upper and lower fixing seats 11 and 12, so as to lock the upper support seat 21 and the lower support seat 22 by a pin.

[0032] When using, Figures 3 to 5, pull out the pins 15 and 56, and simultaneously rotate and lift the upper fixing seat 11, the upper support seat 21 and the upper buckle 51, so that the first bellows 70 (a bellows) is placed on the lower fixing groove 120 of the lower fixing seat 12, and the second bellows 80 (another bellows) is placed on the lower support groove 220 of the lower support seat 22 and the lower buckle 521 of the lower buckle 52. Then, simultaneously rotate the upper fixing seat 11, the upper support seat 21 and the upper buckle 51 in the opposite direction, so that the upper fixing seat 11, the upper support seat 21 and the upper buckle 51 are respectively buckled on the lower fixing groove 120, the lower support groove 220 and the lower buckle 52, and then insert the pin 56 into the sub-pin seat 54 and the female pin seat 55 to lock the upper fixing seat 11, and insert the pin 15 into the sub-pin seat 13 and the female pin seat 14 to lock the upper buckle 51. At this time, the first bellows 70 is clamped in the fixing groove, the second bellows 80 is clamped in the clamping groove and is supported in the supporting groove without being clamped, and the socket 71 of the first bellows 70 and the socket 81 of the second bellows 80 are axially opposite in the horizontal direction.

[0033] Therefore, the operator rotates the driving pulley 63 by the crank 65, and the driving pulley 63 drives the upper and lower driven pulleys 61, 62 to rotate synchronously through the belt 64, and the upper and lower driven pulleys 61, 62 respectively drive the upper and lower lead screws 41, 42 to rotate synchronously at the same time, so that the upper and lower buckles 51, 52 perform synchronous horizontal translation movement along the upper and lower lead screws 41, 42 respectively. Therefore, the second bellows 80 clamped by the upper and lower buckles 51, 52 is translated toward the first bellows 70 under the dragging action of the upper and lower buckles 51, 52, so that the socket 81 of the second bellows 80 is finally firmly inserted into the socket 71 of the first bellows 70, completing the docking operation between the two metal bellows.

[0034] The advantages of the present invention are:

[0035] The present invention ensures that the two bellows are evenly stressed during the docking process, and the docking force can be effectively controlled by manually operating the crank, thereby effectively preventing the bellows from being damaged during the docking process, ensuring reliable and firm docking between the two bellows with high docking quality. The present invention is easy to operate, has high work efficiency, is suitable for implementing docking processes for various metal bellows, and is easy to promote and popularize.

[0036] The above are preferred embodiments of the present invention and the technical principles used therein. For those skilled in the art, any obvious changes such as equivalent transformations, simple replacements, etc. based on the technical solution of the present invention, without departing from the spirit and scope of the present invention, are within the scope of protection of the present invention.
