The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
As can be known from fig. 1 to 10, the anti-disassembly pipe joint comprises two casing pipes 1 with T-shaped cross sections, wherein a first loose joint 2 is sleeved outside the casing pipe 1 on one side, a second loose joint 3 is sleeved outside the casing pipe 1 on the other side, the first loose joint 2 is in threaded connection with the second loose joint 3, sealing covers 4 are sleeved outside the first loose joint 2 and the second loose joint 3, expansion buckles 5 and fixing grooves 6 which are arranged at intervals are uniformly distributed on the end faces of the sealing covers 4, and the expansion buckles 5 and the fixing grooves 6 of the sealing covers 4 on the two sides are matched with each other to hide the first loose joint 2 and the second loose joint 3 inside the sealing covers 4.
When the utility model is used, the water-saving agent is added,
To open the cover 4, the expansion buckle 5 and the fixing groove 6 are broken, which makes it possible to move the two covers 4 away from each other, thus exposing the first and second joints 2 and 3 for the maintenance of the pipeline.
For the convenience of connection, the sleeve 1 is provided with a connecting plate 7, a plurality of limiting holes 8 are uniformly distributed on the connecting plate 7, a sealing gasket 9 is arranged between the connecting plates 7 of the two sleeves 1, the connecting plate 7 can provide a force application point for the sleeve 1, and the first movable joint 2 and the second movable joint 3 are tightly pressed on the connecting plate 7 during threaded connection, so that the sleeves 1 are close to each other, the sealing gasket 9 is squeezed, and the pipeline is watertight.
In order to facilitate operation, the first movable joint 2 comprises a first pipe sleeve 10 sleeved outside the pipe sleeve 1, the end of the first pipe sleeve 10 is connected with a second pipe sleeve 11 positioned outside the connecting plate 7, external threads are arranged on the outer side of the second pipe sleeve 1, a first hexagonal prism 12 is arranged outside the first pipe sleeve 10, a first limiting rod 13 penetrates through the first hexagonal prism 12, the moving direction of the first limiting rod 13 is parallel to the axis of the first movable joint 2, a first spring 14 is sleeved on the first limiting rod 13, and the first spring 14 pushes the first limiting rod 13 outwards.
The second loose joint 3 comprises a third pipe sleeve 15, the end of the third pipe sleeve 15 is connected with a fourth pipe sleeve 16, the inner side of the fourth pipe sleeve 16 is provided with an internal thread matched with the second pipe sleeve 11, the outer part of the third pipe sleeve 15 is provided with a second hexagonal prism 17, a second limiting rod 18 penetrates through the second hexagonal prism 17, the moving direction of the second limiting rod 18 is parallel to the axis of the second loose joint 3, a second spring 19 is sleeved on the second limiting rod 18, and the second spring 19 pushes the second limiting rod 18 outwards.
The first loose joint 2 and the second loose joint 3 are basically the same in structure, and are different in that the second pipe sleeve 11 is an external thread, the fourth pipe sleeve 16 is an internal thread, so that the first loose joint 2 and the second loose joint 3 are in threaded connection, when being fixed, the first loose joint 2 and the second loose joint 3 are turned to the positions where the first limiting rod 13 and the second limiting rod 18 are aligned with the limiting hole 8, so that when the sealing cover 4 pushes the first limiting rod 13 or the second limiting rod 18 to move, the first limiting rod 13 and the second limiting rod 18 can enter the limiting hole 8, the effect of limiting the first loose joint 2 and the second loose joint 3 is achieved, and the automatic opening of the first loose joint 2 and the second loose joint 3 due to some reason is avoided.
The first hexagonal prism 12 and the second hexagonal prism 17 are used outside the first movable joint 2 and the second movable joint 3, so that the operation is convenient, the sealing cover 4 is positioned outside the first hexagonal prism 12 and the second hexagonal prism 17 when in use, the operation position can be covered, the exposed part outside is not easy to operate, and therefore the pipeline is protected from being damaged.
