[0002] Water hoses are widely used in life. In addition to being used in fire-fighting operations after a fire, they can also be used in various liquid transportation situations.
[0003] At present, most of the existing water hose connection joints are snap-on, which have poor fixing effect and are prone to shaking, causing the joints to loosen and fall off, requiring reinstallation, which is time-consuming and labor-intensive. Utility Model Content
[0004] The utility model aims to solve the problem that the existing fixing effect is poor and shaking is easy to occur, and proposes a water hose connecting joint.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] The cam is secured to the side of the hook at the top and has two L-shaped slots for securing the connection between the ends of the cam and the base.
[0007] Furthermore, two sealing rings are clamped on one end of the circumferential outer wall of the connecting pipe.
[0008] Furthermore, an anti-slip ring is sleeved on the circumferential outer wall of the connecting pipe.
[0009] Furthermore, a plurality of reinforcing ribs are fixedly connected to the circumferential inner wall of the connecting pipe.
[0010] Furthermore, one end of the connecting plate is fixedly connected to a shift plate, and one side of the shift plate is provided with an anti-slip groove.
[0011] Furthermore, one end of the spring is fixedly connected to the slider, and the other end of the spring is fixedly connected to the connecting block.
[0012] The beneficial effects of the utility model are:
[0013] 1. Insert one end of the connecting pipe into one end of the mounting pipe and insert the bayonet into the L-shaped slot. Then, twist the connecting pipe to drive the bayonet to rotate, so that the bayonet is engaged with the L-shaped slot. Then, fix the mounting pipe and the connecting pipe by engaging the clamping column and the clamping hook to prevent the joint between the mounting pipe and the connecting pipe from loosening.
[0014] 2. The installation pipe and the connecting pipe can be sealed by the setting of the sealing ring, thereby preventing leakage at the connection between the installation pipe and the connecting pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0020] Reference Figure 1-Figure 3 The circumferential outer wall of the connecting pipe 3 is provided with an anti-slip ring 6, which is convenient for operation of the connecting pipe 3. The circumferential inner wall of the connecting pipe 3 is welded with two bayonet pins 4, which are engaged with the L-shaped slots 2. Insert one end of the connecting pipe 3 into one end of the installing pipe 1 and insert the bayonet pin 4 into the L-shaped slots 2. Then, twist the connecting pipe 3 to drive the bayonet pin 4 to rotate, so that the bayonet pin 4 is engaged with the L-shaped slots 2. One end of the circumferential outer wall of the connecting pipe 3 is connected with two sealing rings 5, thereby sealing between the installing pipe 1 and the connecting pipe 3, thereby preventing leakage at the connection between the installing pipe 1 and the connecting pipe 3. The circumferential outer wall of the connecting pipe 3 is sleeved with an anti-slip ring 6, which is convenient for operation of the connecting pipe 3. The circumferential inner wall of the connecting pipe 3 is welded with a plurality of reinforcing ribs 7, thereby strengthening the firmness of the connecting pipe 3.
[0021] The circumferential outer wall of the connecting tube 3 is fixed with two hooks 8 by bolts, and two mounting plates 9 are welded to the outer walls of both sides of the mounting tube 1. A first rotating rod 10 is rotatably inserted between the two mounting plates 9, and a torsion spring 11 is sleeved on the outer wall of the first rotating rod 10. A connecting plate 12 is fixedly sleeved between the two ends of the first rotating rod 10, and a dial plate is welded at one end of the connecting plate 12. An anti-slip groove is provided on one side of the dial plate to facilitate the operation of the connecting plate 12. A second rotating rod 13 is welded on both sides of the connecting plate 12, and a slider is rotatably sleeved on the other end of the second rotating rod 13. A connecting block 14 is slidably connected to one side of the slider. A spring 16 is sleeved on the outer side of the slider and the connecting block 14. One end of the spring 16 is fixedly connected to the slider, and the other end of the spring 16 is fixedly connected to the connecting block 14. A clamping column 15 is fixed to the other end between the two connecting blocks 14 by a bolt. The clamping column 15 is engaged with the hook 8. The connecting plate 12 is pulled to drive the slider and the connecting block 14 to move, thereby driving the clamping column 15 to move closer to the hook 8 until the clamping column 15 is engaged with the hook 8. Then, the connecting plate 12 is loosened, and the connecting plate 12 is reset under the action of the torsion spring 11, so that the clamping column 15 is clamped with the hook 8, thereby fixing the mounting tube 1 and the connecting tube 3.
[0022] The working principle of this embodiment is as follows: when in use, one end of the connecting tube 3 is inserted into one end of the mounting tube 1, and the bayonet pin 4 is inserted into the L-shaped slot 2. Then, the connecting tube 3 is twisted to drive the bayonet pin 4 to rotate, so that the bayonet pin 4 is engaged with the L-shaped slot 2. Next, the connecting plate 12 is pulled to drive the slider and the connecting block 14 to move, thereby driving the clamping column 15 to approach the hook 8 until the clamping column 15 is engaged with the hook 8. Then, the connecting plate 12 is loosened, and the connecting plate 12 is reset under the action of the torsion spring 11, so that the clamping column 15 is clamped with the hook 8, thereby fixing the mounting tube 1 and the connecting tube 3. Among them, the sealing ring 5 seals between the mounting tube 1 and the connecting tube 3, thereby preventing leakage at the connection between the mounting tube 1 and the connecting tube 3.
[0023] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
