Description

Technical Field

[0001] This utility model relates to the field of fire hose connection technology, and in particular to an anti-torsion quick-release fire hose connection device. Background Technology

[0002] Fire hoses are flexible hoses used to transport water at fire scenes and are an important component of firefighting equipment. When fire hoses are connected to other pipes or another section of fire hose, they are usually connected quickly using quick-release internal couplings. The joints of fire hoses usually need to be clamped and tightened in opposite directions to achieve a tight connection. Internal couplings can be easily unscrewed and disconnected, thus meeting the needs of quick installation and disassembly of fire hoses.

[0003] Existing fire hose couplings with internal fasteners are prone to relative displacement under the pressure of water flow during installation if the coupling is not tightened properly. This can lead to twisting and loosening, affecting the normal use of the fire hose. To address this, we propose an anti-twist quick-release fire hose coupling device. Utility Model Content

[0004] The main objective of this invention is to provide an anti-torsion quick-release fire hose connection device. An anti-torsion mechanism is installed at the quick-release main connector and quick-release auxiliary connector of the fire hose. The main and auxiliary protrusions of the anti-torsion mechanism are fixed at the quick-release main connector and quick-release auxiliary connector, respectively. Then, the main and auxiliary protrusions of the support column are fitted with limiting rings for anti-torsion locking, preventing the quick-release main connector and quick-release auxiliary connector from twisting and loosening due to misoperation. Furthermore, the limiting ring is magnetically connected to the T-shaped magnetic plate of the support column via a magnetic plate with an edge, making it difficult for the limiting ring to fall off after being fitted at the support column. This ensures that the quick-release main connector and quick-release auxiliary connector can effectively resist the torsional stress of the high-pressure water hose, preventing the connector from loosening or falling off, and effectively solving the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A torsion-resistant quick-release fire hose connection device includes a quick-release main connector and a quick-release secondary connector. The quick-release secondary connector is screwed onto the interface of the quick-release main connector. The device also includes an anti-torsion mechanism, comprising a main convex post, a secondary convex post, a screw bolt, a support post, a T-shaped magnetic plate, a retaining ring, a semi-circular liner, and a magnetic plate with an edge. The main convex post and secondary convex post are respectively fixed to the outer shell of the quick-release main connector and the quick-release secondary connector. A screw bolt welded to one end of the support post is screwed into the outer head of the main convex post and the secondary convex post. A T-shaped magnetic plate is clamped and adhered to the outer body of the support post away from the screw bolt. A magnetic plate with an edge is magnetically attracted to the surface of the T-shaped magnetic plate. The magnetic plate with an edge is locked to the retaining ring by bolts. The retaining ring is fitted onto the support post outside the main convex post and the secondary convex post. A semi-circular liner is integrally formed on the retaining ring away from the magnetic plate with an edge, and the semi-circular liner is fitted onto the main body of the support post.

[0007] Furthermore, the outer cylindrical surfaces of the main protrusion and the secondary protrusion are provided with screw-on holes, and screw bolts are screwed into the screw-on holes;

[0008] By adopting the above technical solution, the main convex post and the secondary convex post can be screwed together with a screw bolt through the screw-on hole, so that the main convex post and the secondary convex post can be screwed together to install the support column.

[0009] Furthermore, a side handle is welded to the outer side of the column body of the support;

[0010] By adopting the above technical solution, the support can be rotated by pinching the handle on the side.

[0011] Furthermore, a T-shaped groove is provided at the column head on the other end away from the screw bolt, and a T-shaped magnetic plate is inserted and bonded into the T-shaped groove;

[0012] By adopting the above technical solution, the support column can be inserted into the T-shaped groove to achieve a hidden mounting of the T-shaped magnetic plate, so that the T-shaped magnetic plate at the support column can magnetically attract the edge magnetic plate, thereby retaining the retaining ring outside the support column.

[0013] Furthermore, the inner ring surface of the limiting ring away from the semi-circular liner is provided with a side groove, and a convex edge block with a side magnetic plate is fitted in the side groove. The side magnetic plate is screwed between the side groove wall and the side groove wall.

[0014] By adopting the above technical solution, the convex edge block with the edge magnetic plate can be inserted into the edge fixing groove of the limiting ring, and then the convex edge block with the edge magnetic plate can be locked in the edge fixing groove for installation with the help of bolts.

[0015] Furthermore, rubber friction strips are arranged and bonded to the inner plate surface of the semi-circular liner, and the rubber friction strips press against the column surface of the support.

[0016] By adopting the above technical solution, the semi-circular liner uses rubber friction strips to increase the friction between itself and the support, making it less likely for the semi-circular liner to fall off the support.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model provides an anti-torsion mechanism at the quick-release main connector and quick-release secondary connector of the fire hose. The main protrusion and secondary protrusion of the anti-torsion mechanism are fixed at the quick-release main connector and quick-release secondary connector respectively. Then, the main protrusion and secondary protrusion of the support are fitted with a limiting ring sleeve to prevent the quick-release main connector and quick-release secondary connector from being twisted and loosened due to misoperation.

[0019] Furthermore, the retaining ring is magnetically connected to the T-shaped magnetic plate of the support column through the magnetic plate with the edge, making it difficult for the retaining ring to fall off after it is clamped at the support column. This ensures that the quick-release main connector and quick-release secondary connector can effectively resist the torsional stress of the high-pressure water hose and prevent the connector from loosening or falling off.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1-3As shown, an anti-torsion quick-release fire hose connection device includes a quick-release main connector 1 and a quick-release auxiliary connector 2. The quick-release auxiliary connector 2 is screwed onto the interface of the quick-release main connector 1. It also includes an anti-torsion mechanism 3, which includes a main protrusion 4, an auxiliary protrusion 5, a screw bolt 6, a support column 7, a T-shaped magnetic plate 10, a retaining ring 11, a semi-circular liner 12, and a magnetic plate with an edge 14. The main protrusion 4 and the auxiliary protrusion 5 are respectively fixed to the outer shell of the main housing of the quick-release main connector 1 and the quick-release auxiliary connector 2. A screw bolt 6 is screwed into the inner part of the outer column head, with one end of the support column 7 welded to it. A T-shaped magnetic plate 10 is fastened and bonded to the outer column body of the support column 7 away from the screw bolt 6. The surface of the T-shaped magnetic plate 10 is magnetically attracted to a magnetic plate 14 with an edge. The magnetic plate 14 with an edge is locked to the ring body of the limiting ring 11 by bolts. The ring body of the limiting ring 11 is fitted outside the support column 7 outside the main protrusion 4 and the secondary protrusion 5. A semi-circular liner 12 is integrally formed at the ring body of the limiting ring 11 away from the ring body with the magnetic plate 14 with an edge. The semi-circular liner 12 is fitted outside the main body of the support column 7.

[0026] The outer cylindrical surfaces of the main protrusion 4 and the secondary protrusion 5 are provided with screw-on holes 16, and screw bolts 6 are screwed into the screw-on holes 16.

[0027] By adopting the above technical solution, the main protrusion 4 and the secondary protrusion 5 can be screwed to the bolt 6 through the screw-on hole 16, so that the main protrusion 4 and the secondary protrusion 5 can be screwed to install the support column 7 through the bolt 6.

[0028] The support column 7 has a side handle 8 welded to its outer side;

[0029] By adopting the above technical solution, the support column 7 can be rotated by pinching the handle 8.

[0030] Among them, a T-shaped groove 9 is provided at the column head of the other end of the support column 7 away from the screw bolt 6, and a T-shaped magnetic plate 10 is inserted and bonded into the T-shaped groove 9;

[0031] By adopting the above technical solution, the support column 7 can be inserted into the T-shaped magnetic plate 10 for concealed mounting using the T-shaped groove 9, so that the T-shaped magnetic plate 10 can magnetically attract the edge magnetic plate 14 at the support column 7, thereby retaining the retaining ring 11 outside the support column 7.

[0032] Wherein, the inner ring surface of the limiting ring 11 away from the semi-circular liner 12 is provided with a side fixing groove 13, and a convex edge block with a side magnetic plate 14 is fitted in the side fixing groove 13, and a bolt is screwed between the side magnetic plate 14 and the groove wall of the side fixing groove 13.

[0033] By adopting the above technical solution, the convex edge block of the edge magnetic plate 14 can be inserted into the edge fixing groove 13 of the sleeve limiting ring 11, and then the convex edge block of the edge magnetic plate 14 can be locked in the edge fixing groove 13 for installation with the help of bolts.

[0034] Among them, the inner plate surface of the semi-circular liner 12 is covered with rubber friction strips 15, and the rubber friction strips 15 are pressed against the column surface of the support 7.

[0035] By adopting the above technical solution, the semi-circular liner 12 increases its friction with the support column 7 with the rubber friction strip 15, making it less likely for the semi-circular liner 12 to fall off the support column 7.

[0036] It should be noted that this utility model is an anti-torsion quick-release fire hose connection device. An anti-torsion mechanism 3 is provided at the quick-release main connector 1 and quick-release auxiliary connector 2 for the fire hose. The main protrusion 4 and auxiliary protrusion 5 of the anti-torsion mechanism 3 can be welded and fixed to the main shell of the quick-release main connector 1 and quick-release auxiliary connector 2, respectively. Then, the support column 7 can be installed by screwing the main protrusion 4 and auxiliary protrusion 5 with a screw-on bolt 6. Finally, the T-shaped magnetic plate 10 can be inserted into the T-shaped groove 9 of the support column 7. The internal components are inserted and bonded. Then, the protruding edge block of the magnetic plate 14 can be inserted into the side groove 13 of the limiting ring 11. The protruding edge block of the magnetic plate 14 can then be locked in the side groove 13 with bolts for installation. After the fire hose is fitted onto the rear pipe of the quick-release main connector 1 and quick-release auxiliary connector 2 and secured with wire, the fire hose is quickly connected by rotating the quick-release main connector 1 and quick-release auxiliary connector 2 in opposite directions. Then, the main protrusion 4 of the quick-release main connector 1 and the quick-release auxiliary connector 2... The secondary protrusion 5 is positioned close to each other. Then, the retaining ring 11, in conjunction with the semi-circular liner 12, can be fitted over the support column 7 of the quick-release main connector 1 and quick-release secondary connector 2. The retaining ring 11, with its edge magnetic plate 14, can magnetically attract the T-shaped magnetic plate 10, making it difficult for the retaining ring 11 to detach from the support column 7. Subsequently, the main protrusion 4 and secondary protrusion 5 of the support column 7, in conjunction with the retaining ring 11, provide anti-torsion locking to prevent the quick-release main connector 1 and quick-release secondary connector 2 from twisting and loosening due to misoperation. After the retaining ring 11 is pulled out of the support column 7, the quick-release main connector 1 and quick-release secondary connector 2 can be screwed apart again for quick release. The support column 7 can be pre-installed at the main protrusion 4 and secondary protrusion 5 before the quick-release main connector 1 and quick-release secondary connector 2 are used. Similarly, the magnetic plate 14 with the edge can also be pre-installed at the retaining ring 11. The quick-release main connector 1 and quick-release secondary connector 2 in this utility model are existing fire hose internal buckle connectors on the market. They belong to the screw-on internal buckle structure and can achieve quick disassembly and assembly.
