Description

Technical Field

[0001] The utility model relates to the technical field of water pipe connection, in particular to a fire-fighting water supply pipeline connection assembly device. Background Art

[0002] Firefighting pipes are used to connect firefighting equipment and devices, and to transport firefighting water, gas, or other media. Due to special needs, firefighting pipes have specific thickness and material requirements and are painted red to transport firefighting water. When laying firefighting water supply pipes, two water pipes need to be connected, and the most common connection method is to use flange connection.

[0003] The flange fixing method mainly uses bolts to pass through the flange bolt holes on the two water pipes to achieve assembly and fixation. However, there is a problem in actual installation, that is, the same bolt needs to pass through the adjacent bolt holes on the two flanges at the same time, and the two flanges are not precisely docked. Therefore, it is necessary to manually dock the bolt through the bolt hole of one flange after passing it through the bolt hole of the other flange, or manually adjust the two flanges in advance and observe whether the bolt holes are aligned before installing the bolts to fix them. The two flanges cannot be pre-positioned in advance for quick bolt installation, which is very inconvenient during operation and has low work efficiency.

[0004] In order to solve the above problems, the present application proposes a fire water supply pipe connection assembly device. Utility Model Content

[0020] Embodiment 1, by Figure 1-6 It is given that the utility model includes two water pipes 1, and the ends of the two water pipes 1 close to each other are fixedly connected with a first flange 2 and a second flange 3 respectively. The outer ends of the first flange 2 and the second flange 3 are respectively provided with four first notches 21 and four second notches 31, the first notch 21 is located on one side of the second notch 31, and the first notch 21 and the second notch 31 are connected, four sliding sleeves 4 are fixedly connected to the outer side of the first flange 2, a fastener 5 is slidably connected to the first flange 2 through the sliding sleeve 4, the first flange 2 and the second flange 3 are connected to each other by multiple fasteners 5, four second connecting blocks 6 are fixedly connected at the angle between the water pipe 1 and the first flange 2, and a tension spring 7 is fixedly connected between the fastener 5 and the second connecting block 6.

[0021] The clamping member 5 is composed of a clamping block 51, a sector block 52, a slide plate 53 and a first connecting block 54, and the clamping block 51, the sector block 52, the slide plate 53 and the first connecting block 54 are made of an integral body, the sector block 52 and the slide plate 53 are fixedly connected to both sides of the clamping block 51, and the first connecting block 54 is fixedly connected to the bottom of the slide plate 53. The clamping block 51 passes through the first notch 21 and the second notch 31. The sector block 52 and the slide plate 53 are respectively located on the outside of the second flange 3 and the first flange 2. The slide plate 53 passes through the sliding sleeve 4, and the sliding sleeve 4 and the slide plate 53 are slidably connected. The bottom of the fan-shaped block 52 on the side away from the clamping block 51 is processed into an arc shape, and the maximum thickness of the fan-shaped block 52 is greater than the thickness of the clamping block 51. The bottom of the fan-shaped block 52 on the side away from the clamping block 51 is arc-shaped, so that when it contacts the second flange 3, it can be lifted up more smoothly by the second flange 3. At the same time, when the fan-shaped block 52 passes over the first flange 2 and the second flange 3, and when the clamping block 51 is clamped into the first notch 21 and the second notch 31, the fan-shaped block 52 is thicker than the clamping block 41, and the raised part will clamp the second flange 3, making it impossible for the first flange 2 and the second flange 3 to be separated from each other, making it more convenient to assemble the bolts.

[0022] The four first notches 21 and the four second notches 31 are respectively distributed in a circular array with the central axis of the first flange 2 and the second flange 3. In addition to the first notch 21 and the second notch 31, the number of the clips 5 used therewith is also four, and the four clips 5 are also distributed in a circular array with the central axis of the first flange 2 and the second flange 3. The central axes of the water pipe 1, the first flange 2 and the second flange 3 coincide. In this way, when connecting and assembling two water pipes 1, it is only necessary to initially position the first flange 2 and the second flange 3 close to each other to be clipped 5, and then rotate the first flange 2 and the second flange 3 separately, and the corresponding water pipes 1 rotate synchronously. When the first notch 21 and the second notch 31 are connected, the clip 5 is pulled by the tension spring 7 and clipped into the first notch 21 and the second notch 31. At this time, the first flange 2 and the second flange 3 will neither separate from each other nor rotate separately, and the bolt holes on the first flange 2 and the second flange 3 are in an aligned and connected state.

[0023] There are eight bolt holes on the first flange 2 and the second flange 3. The sliding sleeve 4 is located between two adjacent bolt holes. The eight bolt holes are distributed in a circular array on the first flange 2 and the second flange 3. There are four first notches 21, second notches 31 and snap fasteners 5 for positioning the first flange 2 and the second flange 3. Therefore, no matter which second notch 31 on the second flange 3 the snap fastener 5 is inserted into, the bolt holes on the first flange 2 and the second flange 3 are aligned and connected.

[0024] Working principle:

[0025] When connecting and assembling two water pipes 1, the first flange 2 and the second flange 3 are mainly connected together by bolts to achieve the connection and assembly of the two water pipes 1;

[0026] When the first flange 2 and the second flange 3 are put together and the bolts are passed through the bolt holes, the second flange 3 can be first brought close to the first flange 2 until the clip 5 on the first flange 2 comes into contact with the second flange 3. When the second flange 3 continues to approach the first flange 2, the clip 5 will be squeezed. The shape of the fan-shaped block 52 on the clip 5 will cause the clip 5 to be squeezed by the second flange 3 to move away from the central axis of the first flange 2, until the second flange 3 moves close to the first flange 2 and between the fan-shaped blocks 52 in the multiple clips 5. During this period, the tension spring 7 between the clip 5 and the second connecting block 6 is stretched to generate elastic force, which is manifested as Figure 5 As the second flange 3 continues to approach the first flange 2, until the sector block 52 passes over the second flange 3, the clip 5 is pulled by the tension spring 7 to move a little distance toward the center axis of the first flange 2 and the second flange 3. In this state, the block 51 is pressed on the outer edge of the second flange 3. Restricted by the sector block 52 on the clip 5, the second flange 3 can no longer move away from the first flange 2 and can only rotate about its center axis. At this time, it is shown as Figure 6 Status;

[0027] After the first flange 2 and the second flange 3 are preliminarily positioned, rotate the water pipe 1 and the first flange 2 or the water pipe 1 and the second flange 3. There is no need to consider the accuracy during rotation, and you can rotate it at will. The purpose is to ensure that the first notch 21 and the second notch 31 can be connected. When the first notch 21 and the second notch 31 are connected, the tension spring 7 will pull the fastener 5 to move toward the central axis of the first flange 2 and the second flange 3 until the block 51 is stuck in the first notch 21 and the second notch 31. In this state, the first flange 2 and the second flange 3 can neither move away from each other nor rotate independently, but at this time the bolt holes on the first flange 2 and the second flange 3 are in a connected state. Then, the first flange 2 and the second flange 3 can be fixed directly by passing the bolts through the bolt holes on the first flange 2 and the second flange 3, thereby realizing the quick connection and assembly of the two water pipes 1.
