The operation is simple, the use is convenient, and the workload of the staff is reduced.

[0007] Furthermore, one end of the spring rod away from the fixing slot is fixedly connected to a magnetic block that repels the magnet, and the one end of the spring rod away from the fixing slot passes through the interior of the rotating ring.

When the magnet is aligned with the magnetic block, the spring rod is inserted into the fixed groove under the action of the magnet and the magnetic block, and the annular tube and the fixed tube can be connected. The operation is simple and the work efficiency of the staff is improved.

[0009] Furthermore, four groups of limiting rods are symmetrically fixedly connected to the inner wall of the annular tube, and limiting grooves matching the limiting rods are opened on the inner wall of the fixed tube.

[0010] By adopting the above technical solution, the annular tube and the fixed tube are limited in use through the mutual cooperation of the limiting rod and the limiting groove.

A fixed tube 114 is movably provided at the end of the annular tube 112 away from the bend pipe main body 100, and a fixing groove 1143 matching the spring rod 1121 is opened on the outer wall of the fixed tube 114, and a connecting tube 115 is fixedly connected to the end of the fixed tube 114 away from the annular tube 112.

[0029] When the bent pipe body 100 needs to be connected for use, the annular tube 112 is connected to the fixed tube 114, and the rotating ring 113 is rotated. The rotating ring 113 cooperates with the magnet 1136 to drive the spring rod 1121 to move, and the spring rod 1121 is inserted into the fixed groove 1143 to connect the annular tube 112 and the fixed tube 114. The fixing rod 1133 is inserted into the second connecting block 1152 to fix the annular tube 112 and the fixed tube 114. The operation is simple, the use is convenient, and the workload of the staff is reduced.

[0030] See also Figure 3 、 Figure 4 、 Figure 5 One end of the spring rod 1121 away from the fixed slot 1143 is fixedly connected to a magnetic block that repels the magnet 1136 , and the other end of the spring rod 1121 away from the fixed slot 1143 passes through the interior of the rotating ring 113 .

[0031] By rotating the rotating ring 113, the rotating ring 113 drives the magnet 1136 to rotate. When the magnet 1136 is aligned with the magnetic block, the spring rod 1121 is inserted into the fixed groove 1143 under the action of the magnet 1136 and the magnetic block, and the annular tube 112 and the fixed tube 114 can be connected. The operation is simple and the work efficiency of the staff is improved.

[0032] See also Figure 2 、 Figure 3 、 Figure 4 Four groups of limiting rods 111 are symmetrically fixedly connected to the inner wall of the annular tube 112 , and a limiting groove 1142 matching the limiting rod 111 is opened on the inner wall of the fixed tube 114 .

[0033] The annular tube 112 and the fixed tube 114 are limited in position by the cooperation between the limiting rod 111 and the limiting groove 1142 .

[0034] See also Figure 3 and Figure 4One end of the fixed tube 114 away from the connecting tube 115 is fixedly connected to a pressing block 1141 , and the pressing block 1141 is aligned with the airbag 1122 .

[0035] When the fixed tube 114 is connected to the annular tube 112 , the airbag 1122 is squeezed by the pressing block 1141 , so that the connection between the fixed tube 114 and the annular tube 112 is sealed by the airbag 1122 .

[0036] See also Figure 2 、 Figure 3 、 Figure 4 The outer wall of the connecting tube 115 is symmetrically fixedly connected with multiple groups of spring beads 1151, and the inner wall of the rotating ring 113 is provided with a card slot 1131 matching the spring beads 1151.

[0037] When the spring bead 1151 is engaged with the slot 1131, the jam tube generated during the engagement can easily remind the staff that the spring rod 1121 is just engaged with the fixing slot 1143, thereby improving the work efficiency of the staff.

[0038] See also Figure 3 and Figure 4 The end of the rotating ring 113 close to the fixed tube 114 is fixedly connected to the first connecting block 1132, and a fixed rod 1133 is movably inserted into the surface of the first connecting block 1132. A spring is fixedly sleeved on the outer wall of the fixed rod 1133, and one end of the spring is fixedly connected to the first connecting block 1132. One end of the fixed rod 1133 is rotatably connected to the rotating block 1134, and the outer wall of the rotating ring 113 is fixedly connected to the limiting block 1135.

[0039] By inserting the fixing rod 1133 into the second connecting block 1152, the rotating ring 113 can be limited for use. When the fixing tube 114 needs to be connected to the annular tube 112, the rotating block 1134 is pulled and then rotated, and the fixing rod 1133 is limited by the limiting block 1135, thereby facilitating the connection between the fixing tube 114 and the annular tube 112.

[0041] By engaging the fixing rod 1133 with the second connecting block 1152 , the rotating ring 113 can be limited, thereby facilitating the fixed connection between the fixing tube 114 and the annular tube 112 .

[0042] The working principle of the present invention is as follows: when the elbow body 100 needs to be used, the fixed tube 114 is docked with the annular tube 112, the fixed tube 114 and the annular tube 112 are limited by the matching limiting groove 1142 and the limiting rod 111, and the pressing block 1141 squeezes the airbag 1122, and the fixed tube 114 and the annular tube 112 are limited by the airbag 1122.

[0043] Furthermore, by pulling the fixed rod 1133, the fixed rod 1133 is limited by the limit block 1135 and the rotating block 1134, and then by rotating the rotating ring 113, the rotating ring 113 drives the magnet 1136 to rotate.
