[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] The utility model provides Figure 1-8 As shown, a fire hose connection assembly includes two connecting heads 1, two arc-shaped mounting blocks 2 are provided on the two connecting heads 1, two fixing sleeves 3 are slidably installed on the two arc-shaped mounting blocks 2, and two limiting assemblies are respectively provided on the two fixing sleeves 3, and the limiting assembly includes a push rod 4, a push block 5, two limiting rods 6 and two limiting grooves 7, the push rod 4 is slidably installed on the corresponding fixing sleeve 3, the push block 5 is rotatably installed on the top of the push rod 4, the two limiting rods 6 are fixedly installed on the top of the corresponding fixing sleeve 3, the two limiting grooves 7 are both opened at the bottom of the push block 5, the two limiting grooves 7 are respectively slidably connected to the corresponding limiting rods 6, and the two arc-shaped mounting blocks 2 are respectively provided with two fixing assemblies.

[0026] like Figure 6 As shown, the fixing assembly includes a groove 8, a clamping block 9, two connecting blocks 10, an L-shaped block 11 and a spring 12. The groove 8 is opened at the top of the arc-shaped mounting block 2, the clamping block 9 is fixedly mounted on the bottom inner wall of the groove 8, and the two connecting blocks 10 are fixedly mounted on the top inner wall of the groove 8. The L-shaped block 11 is hingedly mounted on the two connecting blocks 10, and the spring 12 is fixedly mounted on the top inner wall of the groove 8. The bottom end of the spring 12 is fixedly connected to the top of the L-shaped block 11. More specifically, the L-shaped block 11 is hinged on the two connecting blocks 10, so that the L-shaped block 11 can be adjusted in angle. The spring 12 releases the elastic force after the L-shaped block 11 is deflected, so that the L-shaped block 11 can be restored to its original shape, and the L-shaped block 11 is clamped by the clamping block 9.

[0027] In addition, the fixing assembly also includes a slide groove 13, a slide rod 14 and a slider 15. The slide groove 13 is opened at the top of the L-shaped block 11, the slide rod 14 is fixedly installed in the slide groove 13, and the slider 15 is slidably installed on the slide rod 14. The slider 15 is hinged to the bottom end of the corresponding push rod 4. More specifically, when the push rod 4 moves downward, the push rod 4 presses one side of the L-shaped block 11 to deflect downward, and at the same time, the slider 15 slides on the slide rod 14, thereby facilitating the fixing sleeve 3 to fix the two arc-shaped mounting blocks 2.

[0028] like Figure 8 As shown, in some embodiments, a circular hole is opened on the outer wall of one side of the multiple sliders 15, and two balls are movably embedded in the multiple circular holes. The multiple balls are respectively slidably connected to the corresponding sliding rods 14. More specifically, while allowing the slider 15 to slide on the sliding rod 14, the balls can reduce the friction generated when the slider 15 slides on the sliding rod 14.

[0029] In some embodiments, two sealing gaskets 16 are respectively fixedly installed on the two arc-shaped mounting blocks 2, and the multiple sealing gaskets 16 are respectively adapted to the corresponding connectors 1. More specifically, the sealing gaskets 16 can seal the gap between the arc-shaped mounting block 2 and the two connectors 1 to prevent water from flowing out of the gap due to excessive water pressure.

[0030] In some embodiments, a positioning block 17 is fixedly installed on the outer wall of the two connecting heads 1, and two positioning blocks 18 are fixedly installed on the two arc-shaped mounting blocks 2. More specifically, the positioning block 17 is stuck between the arc-shaped mounting block 2 and the positioning block 18, which can prevent the arc-shaped mounting block 2 from moving, so that the arc-shaped mounting block 2 can install the two connecting heads 1 more firmly.

[0031] In some embodiments, a sealing block 19 is fixedly installed on the inner wall of the two arc-shaped mounting blocks 2, and a mounting groove 20 is opened on the inner wall of the corresponding connector 1. An inner ring 21 is fixedly installed on one end of the corresponding connector 1, and a sealing ring 22 is fixedly installed on the outer wall of the inner ring 21. The sealing ring 22 is adapted to the mounting groove 20. More specifically, the sealing block 19 can seal the connection between the two connectors 1, and the sealing ring 22 on the inner ring 21 can not only perform sealing, but also increase the friction between the inner ring 21 and the mounting groove 20, so that the connection between the two connectors 1 is more firmly established.

[0032] Working principle:

[0033] Step 1: Insert the connector 1 with the inner ring 21 into the connector 1 with the mounting groove 20, increase the friction and sealing through the sealing ring 22, so as to achieve the initial connection of the two connectors 1, and then place the positioning block 17 between the arc-shaped mounting block 2 and the positioning block 2 18 to limit the two arc-shaped mounting blocks 2, and the sealing block 19 seals the connection gap between the two connectors 1.

[0034] Step 2: Press the push rod 4 through the push block 5, so that the push rod 4 presses the L-shaped block 11 downward, and the L-shaped block 11 deflects the angle and squeezes the spring 12 at the same time. Put the fixing sleeve 3 on the two arc-shaped mounting blocks 2, let the L-shaped block 11 pass over the clamping block 9, and then pull the push rod 4 upward, rotate the push block 5 so that the limit groove 7 is aligned with the limit rod 6, release the push block 5 and let the limit rod 6 be stuck in the limit groove 7 to limit the push rod 4.
