[0002] Mortar conveying hoses are mainly used for conveying viscous materials such as cement mortar. They adopt a non-sealed structure, with the mortar only in contact with the inner cavity of the hose, avoiding the environmental pollution and equipment corrosion problems caused by traditional shaft seals or filler seals. Mortar conveying hoses are usually connected using traditional clamps or flanges at the hose joint. However, mortar conveying hoses using a single clamp or flange connection are easily subjected to pressure and vibration impact, which can lead to loosening of the conveying hose connection and leakage. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a mortar conveying hose connection structure that prevents leakage is provided. This solves the problem that mortar conveying hoses using a single clamp or flange connection are easily subjected to pressure and vibration impacts, leading to loosening of the hose connection and leakage.

[0004] To achieve the above objectives, a mortar conveying hose connection structure to prevent spillage is provided, comprising: a mortar conveying hose body, wherein a metal pipe head is provided at the side end of the mortar conveying hose body. The mortar conveying hose body is inserted into the pipe connector via a metal pipe head. The pipe connector has an SMA sealing ring fixed on its surface. The SMA sealing ring is inserted and fitted into the inner wall of the metal pipe head. The side end of the pipe connector is engaged with the side end of the metal pipe head via a sealing gasket. The inner side of the pipe connector is pressed against the outer surface of the metal pipe head via a leak-proof gasket. The outer end of the pipe connector is fixed with a multi-claw clamp and a hose clamp.

[0005] Furthermore, the metal tube head has a concave annular snap-fit ​​groove on its side end face, and a positioning protrusion is welded to the inner wall of the metal tube head.

[0006] Furthermore, the outer end face of the SMA sealing ring is provided with a connecting groove, and the groove face of the connecting groove is correspondingly fitted with a positioning protrusion.

[0007] Furthermore, the inner side of the pipe connector is provided with a connecting cavity; and the connecting cavity is connected to the inner cavity of the mortar conveying hose body connected at both ends.

[0008] Furthermore, the multi-claw clamp is located on the outside of the pipe connector and the metal pipe head insertion end.

[0009] Furthermore, a leak-proof washer is fitted into the inner groove of the pipe connector, and an arc-shaped plate is symmetrically pressed onto the outer end face of the leak-proof washer.

[0010] Furthermore, an elastic pressure block is bonded to the outer surface of the arc-shaped plate; and the elastic pressure block is located through the groove wall of the pipe connector, with a hose clamp squeezed and tightened on the outside of the elastic pressure block.

[0011] The beneficial effects of this utility model are as follows: the anti-leakage mortar conveying hose connection structure of this utility model utilizes the SMA sealing ring on the inner side of the pipe connector to be inserted into the mortar conveying hose head, and is compressed and sealed by the sealing gasket and the leak-proof gasket. Then, the multi-claw clamp and the hose clamp are fixed to the outer pipe wall, realizing a multi-connection structure of the mortar conveying hose.

[0017] Reference Figures 1 to 4 As shown, this utility model provides a mortar conveying hose connection structure to prevent leakage and spillage, including: a mortar conveying hose body 1, and a metal pipe head 11 provided on the side end of the mortar conveying hose body 1. The mortar conveying hose body 1 is inserted into the pipe connector 2 via the metal pipe head 11. The pipe connector 2 is fixed with an SMA sealing ring 23 on its surface. The SMA sealing ring 23 is inserted and fitted into the inner wall of the metal pipe head 11. The side end of the pipe connector 2 is engaged with the side end locking groove 12 of the metal pipe head 11 via a sealing gasket 22. The inner side of the pipe connector 2 is pressed against the outer surface of the metal pipe head 11 via a leak-proof gasket 5. The outer end of the pipe connector 2 is fixed with a multi-claw clamp 3 and a hose clamp 4.

[0018] When installing the multi-end mortar conveying hose body 1, first insert the SMA sealing rings 23 (after heating) at both ends of the pipe connector 2 into the metal pipe heads 11 of the two sections of the mortar conveying hose body 1, so that the sealing gaskets 22 are clamped and pressed on the side end face of the metal pipe head 11. At this time, use the multi-claw clamp 3 to clamp and fix the metal pipe head 11 and the pipe connector 2 on the outside. Then use the hose clamp 4 to fix it at the protruding elastic pressure block 52, and squeeze the elastic pressure block 52 into the groove of the pipe connector 2, so that the inner leak-proof gasket 5 is elastically pressed on the surface of the metal pipe head 11, further preventing the leakage of mortar, effectively compensating for the loosening of the connection caused by mortar impact and vibration, enhancing the sealing and pressing performance of the mortar conveying hose connection structure, and ensuring that the multi-section connected conveying hose can stably convey mortar.

[0019] In this embodiment, a concave annular snap-fit ​​groove 12 is provided on the side end face of the metal pipe head 11, and a positioning protrusion 13 is welded to the inner wall of the metal pipe head 11. A connecting groove 24 is provided on the outer end face of the SMA sealing ring 23, and the positioning protrusion 13 is correspondingly inserted and fitted into the groove face of the connecting groove 24. A connecting cavity 21 is provided inside the pipe connector 2; and the connecting cavity 21 is connected to the inner cavity of the mortar conveying hose body 1 connected at both ends.

[0020] In a preferred embodiment, the positioning protrusion 13 is positioned and inserted into the SMA sealing ring 23, effectively preventing the SMA sealing ring 23 from sliding or rotating inside the metal pipe head 11, which would affect the fixing of the clamp. The SMA sealing ring 23 utilizes the properties of shape memory alloy (SMA). When the SMA sealing ring 23 is installed (preheated), it is in an austenitic state (shrinkage state). After installation, as the temperature decreases, the SMA sealing ring 23 returns to its memory shape (slightly expands), providing additional radial sealing pressure to compensate for loosening of the connection caused by mortar impact and vibration.

[0021] In this embodiment, the multi-claw clamp 3 is locked and fixed at the outer side of the insertion end between the pipe connector 2 and the metal pipe head 11. A leak-proof washer 5 is sleeved in the inner groove of the pipe connector 2, and an arc-shaped plate 51 is symmetrically pressed on the outer end face of the leak-proof washer 5. An elastic pressure block 52 is bonded to the outer surface of the arc-shaped plate 51; and the elastic pressure block 52 penetrates through the groove wall of the pipe connector 2, and a hose clamp 4 is squeezed and tightened on the outer side of the elastic pressure block 52.

[0022] As a preferred embodiment, the multi-claw clamp 3 provides a uniform radial locking force to firmly secure the pipe connector 2 to the outer end of the metal pipe head 11. The leak-proof gasket 5, pushed by the elastic pressure block 52 under compression, is tightly pressed against the outer surface of the pipe connector 2, forming a central sealing layer with the sealing gasket 22, thereby further preventing mortar leakage and ensuring stable mortar delivery from the multi-section connected conveying hose.

[0023] This utility model's leak-proof mortar conveying hose connection structure effectively solves the problem that mortar conveying hoses using a single clamp or flange connection are easily subjected to pressure and vibration impacts, leading to loose connections and leaks. It achieves a multi-connection structure for the mortar conveying hose, effectively compensating for loose connections caused by mortar impacts and vibrations, enhancing the sealing and compression of the mortar conveying hose connection structure, preventing mortar leakage at the joints, and ensuring stable mortar delivery through multi-section connected conveying hoses. It is suitable for leak-proof mortar conveying hose connection structures.
