The inner diameter of the first sleeve 210 is adapted to the outer diameter of the end of the pipe body 100 so that a seal is maintained between the first sleeve 210 and the pipe body 100. A plurality of main stoppers 220 are fixedly mounted at both ends of the inner circumference of the first sleeve 210, respectively.
The main stoppers 220 are uniformly distributed around the axial line of the first sleeve 210 and correspond to the sliding grooves 110 one by one. The width of the main stopper 220 is adapted to the sliding groove 110, and the length thereof is adapted to the stopper groove 120.
Two sides of any one of the main stoppers 220 are respectively provided with an auxiliary stopper 230. The auxiliary limiting block 230 is slidably connected to the main limiting block 220, and has one end located inside the main limiting block 220 and the other end extending outside the main limiting block 220. The two sides of one end of the auxiliary limiting block 230, which is far away from the main limiting block 220, are cut with first inclined planes 231, so that under the action of the first inclined planes 231, the auxiliary limiting block 230 can be pushed into the main limiting block 220 in the process that the main limiting block 220 slides to the limiting groove 120. And the other end of the sub stopper 230 is fitted into the stopper hole 130.

The adjusting bolt 260 has a threaded end located in the first mounting hole 221 and threadedly coupled to the locking block 250 and another end located outside the first mounting hole 221 and rotatably coupled to the first sleeve 210. Thus, the locking block 250 can be moved by rotating the adjusting bolt 260, and when the locking block 250 moves to be clamped between the two secondary limiting blocks 230, the two secondary limiting blocks 230 cannot slide, i.e. are locked. When the locking block 250 moves out of the two sub stoppers 230, the two sub stoppers 230 may slide along the first mounting holes 221, i.e., be unlocked.
When the sliding type locking device is used, before installation, the auxiliary limiting block 230 is pressed to see whether the auxiliary limiting block can slide or not, namely whether the auxiliary limiting block is locked or not. If not locked, installation may begin. If the locking piece is locked, the adjusting bolt 260 is rotated to move the locking piece 250 away from the axis of the first sleeve 210 until the locking piece 250 unlocks the two secondary limiting blocks 230, so that the installation can be performed.
When the pipe fitting is installed, the first sleeve 210 is fitted over the pipe body 100. The first sleeve 210 is rotated such that the main stopper 220 corresponds to the slide groove 110. The connecting device 200 is pushed toward the pipeline body 100 until the main stopper 220 abuts against the sliding groove 110. The sub stopper 230 facing the side of the duct body 100 at this time is pushed into the first mounting hole 221.
The connecting device 200 is rotated, and the sub-stopper 230 at a side away from the pipe body 100 is also pushed into the first mounting hole 221 by the first inclined surface 231. When the main stopper 220 abuts against the stopper groove 120, the auxiliary stopper 230 corresponds to the stopper hole 130, and the auxiliary stopper 230 is pushed into the stopper hole 130 by the first return spring 240.

Another pipeline body 100 is inserted into the first sleeve 210, the pipeline body 100 is rotated until the sliding groove 110 on the pipeline body 100 corresponds to the main limiting block 220 on the first sleeve 210, then the pipeline body 100 is pushed until the main limiting block 220 is abutted to the sliding groove 110 of the pipeline body 100, the pipeline body 100 is rotated again, the main limiting block 220 is abutted to the limiting groove 120, the adjusting bolt 260 is adjusted, the auxiliary limiting block 230 is locked, the connection of the two pipeline bodies 100 is completed, the operation is repeated, and the installation of the fire fighting pipeline can be completed quickly.
In one embodiment, the end of the pipe body 100 is coaxially opened with a sealing groove 140. Specifically, the seal groove 140 is located at an end of the pipe body 100 and is coaxial with the pipe body 100.
The second sleeve 270 is coaxially installed in the middle of the first sleeve 210, and specifically, the second sleeve 270 is located inside the first sleeve 210 and is fixedly connected to the first sleeve 210. A sealing ring 280 is coaxially installed at each end of the second sleeve 270.
The sealing ring 280 is slidably connected to the second sleeve 270, and has one end located in the second sleeve 270 and the other end extending out of the second sleeve 270.
Specifically, the two ends of the second sleeve 270 are respectively provided with a second mounting hole 271, the sealing ring 280 is slidably connected to the second sleeve 270 through the second mounting hole 271, and one end of the sealing ring 280 is located in the second mounting hole 271, and the other end of the sealing ring 280 extends out of the second mounting hole 271.
The end of the seal ring 280 remote from the second sleeve 270 is fitted into the seal groove 140.
A second return spring 290 is installed at one end of the sealing ring 280 located in the second sleeve 270, and both ends of the second return spring 290 respectively abut against the sealing ring 280 and the second sleeve 270.
Specifically, the second return spring 290 is installed in the second installation hole 271, and both ends of the second return spring 290 respectively abut against the sealing ring 280 and the second sleeve 270, and in a natural state, the second return spring 290 bears a pressure to provide a stress for keeping the sealing ring 280 at the end of the second installation hole 271.
Thus, when the connection device 200 or the pipe body 100 is pushed, the sealing ring 280 is pushed to compress the second return spring 290, so that the sealing is maintained, thereby improving the sealing performance between the connection device 200 and the pipe body 100.
In one embodiment, the sealing groove 140 is stepped, and an end of the sealing ring 280 extending into the sealing groove 140 is adapted to the sealing groove 140, i.e., the end of the sealing ring 280 is also stepped and adapted to the sealing groove 140. The sealing effect is improved by the cooperation of the stepped sealing groove 140 and the stepped sealing ring 280.
In one embodiment, a second inclined surface 121 is cut at an end of the limiting groove 120 facing the sliding groove 110, and the second inclined surface 121 is adapted to the first inclined surface 231. Thus, the sub stopper 230 can be more easily pushed into the first mounting hole 221 by the first and second inclined surfaces 231 and 121.
This structure facilitates the installation.
In addition, the first sleeve 210 may be designed as two sub-sleeves which are oppositely arranged and are respectively rotatably connected with the second sleeve 270 and kept sealed, so that when installing, only the sub-sleeves need to be rotated, and the pipeline body 100 does not need to be rotated when installing the other pipeline body 100.
