DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a fire-fighting pipe connection structure, including a connector 17 installed at the end of a fire-fighting pipe 1, the connectors 17 at the ends of two adjacent fire-fighting pipes 1 correspond to each other, a sealing and waterproof structure is installed between the two connectors 17, a connecting plate 12 is installed on the fire-fighting pipe 1, a plurality of bolts 16 are installed between the two connecting plates 12, a fixing ring 7 is installed on the fire-fighting pipe 1, a telescopic rod 6 is installed between the fixing ring 7 and the connecting plate 12, a shell 13 is fixed to one of the connecting plates 12, and a plurality of first fixing plates 2 and second fixing plates 3 are fixed on the indoor ceiling of the building, the first fixing plate 2 corresponds to the fixing ring 7, and the second fixing plate 3 corresponds to the shell 13.

[0022] In this embodiment, the sealing and waterproof structure includes a sealing block 9 and a water retaining strip 10. The sealing block 9 is fixedly connected to one of the connecting heads 17. A groove 8 is provided in the other connecting head 17. The groove 8 corresponds to the sealing block 9. The water retaining strip 10 is located on the peripheral side of the connecting head 17. A partition 11 is fixed on one of the connecting plates 12.

[0023] Specifically, when the two connecting heads 17 are butt-jointed, the sealing block 9 is inserted into the groove 8 to form a first layer of waterproof structure, and then the water retaining strip 10 is sleeved on the surrounding side of the connecting head 17. At this time, the water retaining strip 10 is stuck between the connecting head 17 and the partition 11 to form a second layer of waterproof structure. The two-layer waterproof sealing structure can achieve a better waterproof effect and prevent water leakage at the joints.

[0024] A plurality of through slots 18 are defined in the connecting plate 12 , and the through slots 18 correspond to the bolts 16 .

[0025] The bolts 16 pass through the through slots 18 to fix the two connecting plates 12 together, thereby achieving the installation of the device.

[0026] The first pull rod 4 is fixed between the first fixing plate 2 and the fixing ring 7. The fixing ring 7 is fixedly connected to the telescopic rod 6, and one end of the telescopic rod 6 is in contact with each other.

[0027] Specifically, when installing the fire-fighting pipe 1, the two fire-fighting pipes 1 are connected through the fixing ring 7. At this time, the length of the telescopic rod 6 is adjusted so that the telescopic rod 6 pushes the connecting plate 12, so that the two connecting plates 12 are squeezed to prevent the connecting plates 12 from having gaps due to loose bolts, thereby achieving a stable support effect.

[0028] A second pull rod 5 is fixed to the lower side of the second fixed plate 3, and a support ring 14 is fixed to one end of the second pull rod 5. The support ring 14 corresponds to the outer shell 13. A swivel 15 is rotatably fitted inside the support ring 14. The swivel 15 is threadedly fitted with the outer shell 13. The fire-fighting pipe 1 and the connector 17 are an integrated structure.

[0029] Specifically, the support ring 14 can support the connection. During installation, the swivel 15 is rotated so that the outer shell 13 enters the swivel 15, and the two fire-fighting pipes 1 are installed on the opposite inner sides of the outer shell 13. Then, the connection of the fire-fighting pipes 1 can be supported by the support ring 14, thereby ensuring that the joint does not tilt and cause water leakage.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
