Two groups, through the elastic force of the two groups of springs 26, the arc plate C23 and the arc plate D24 are respectively moved downward along the outer periphery of the guide rod 25 without being affected by external forces. The outer wall of the arc plate C23 is installed and disassembled with the arc plate D24 through the assembly and disassembly component 3. The assembly and disassembly component 3 is convenient for limiting the arc plate C23 and the arc plate D24, so as to facilitate the installation of the elastic component 2 on the hose body 1. The bottoms of the arc plates C23 and D24 are fixedly connected with cylindrical rods 27. There are two groups of cylindrical rods 27 symmetrically distributed. The two groups of cylindrical rods 27 are used to guide the arc plates A21 and B22 respectively to prevent the arc plates A21 and B22 from deviating during movement. An early warning component 28 is arranged on the cylindrical rod 27. Through the early warning component 28, a warning light can be emitted to warn and remind the surrounding staff, and the alarm range can be preset.
[0034] Reference Figure 3 and Figure 4 The assembly and disassembly component 3 includes an insert block 31, and the top inner wall of the insert block 31 is elastically connected to a wedge block 32 through a compression spring 33. Through the elastic force of the compression spring 33, the wedge block 32 always maintains a clamping effect with the slot when not affected by external force, thereby limiting the arc plate C23 and the arc plate D24. A slot is provided at the top right end of the arc plate C23.
[0035] Reference Figure 2 and Figure 5The warning component 28 includes a block 281, a button 282 is provided at the top right end of the block 281, and the warning light 283 can be activated by pressing the button 282. The warning light 283 is fixedly connected to the front right end of the block 281. By activating the warning light 283, a warning light can be generated to remind the surrounding staff. The inner wall of the block 281 is elastically connected with a clamping block 286 through a limit spring 285.

[0036] Reference Figure 2 The outer periphery of the guide rod 25 penetrates and is slidably connected to the inner wall of the bottom right end of the arc plate C23. When high pressure expansion is generated at the joint of the hose body 1, the arc plate C23 and the arc plate D24 will be squeezed, and the arc plate A21 and the arc plate B22 will also be squeezed, so that the arc plate C23 and the arc plate D24 slide along the outer peripheries of the two groups of guide rods 25 respectively, and the arc plate A21 and the arc plate B22 slide along the outer peripheries of the two groups of cylindrical rods 27 respectively. One end of the spring 26 is fixedly connected to the top of the guide rod 25, and the other end of the spring 26 is fixedly connected to the top right end of the arc plate C23. Through the fixing effect of the spring 26, the spring 26 remains fixed to prevent the spring 26 from falling off. The outer periphery of the cylindrical rod 27 penetrates and is slidably connected to the inner wall of the top right end of the arc plate A21. When the arc plate A21 and the arc plate B22 slide, the button 282 will be squeezed to turn on the warning light 283.
[0037] Reference Figure 3 The right side of the plug block 31 is fixedly connected to the left top end of the arc plate D24, and the fixing effect of the plug block 31 prevents the plug block 31 from falling off. The outer wall of the plug block 31 is plugged into the inner wall of the arc plate C23. One end of the compression spring 33 is fixedly connected to the top inner wall of the plug block 31, and the other end of the compression spring 33 is fixedly connected to the bottom of the wedge block 32. The fixing effect of the compression spring 33 keeps the wedge block 32 fixed to prevent the wedge block 32 from falling off. The outer wall of the wedge block 32 is slidably connected to the top inner wall of the plug block 31. The sliding effect of the wedge block 32 allows the wedge block 32 to be engaged or released from the slot. The outer wall of the wedge block 32 is engaged with the inner wall of the slot. The engaging effect of the wedge block 32 and the slot limits the arc plate C23 and the arc plate D24.
[0038] Reference Figure 5The top inner wall of the block 281 penetrates and is slidably connected to the outer periphery of the cylindrical rod 27. Through the sliding effect of the block 281, the height position of the button 282 is adjusted, thereby adjusting the trigger range of the button 282. The button 282 is electrically connected to the warning light 283. The outer periphery of the pull rod 284 penetrates and is slidably connected to the right inner wall of the block 281. Through the sliding effect of the pull rod 284, the block 286 is driven to slide. One end of the limit spring 285 is fixedly connected to the inner wall of the block 281, and the other end of the limit spring 285 is fixedly connected to the outer wall of the block 286. Through the fixing effect of the limit spring 285, the block 286 is kept fixed to prevent the block 286 from falling off. The outer wall of the block 286 is slidably connected to the inner wall of the block 281. Through the sliding effect of the block 286, the block 286 is engaged with or released from the circular hole, and the outer wall of the block 286 is engaged with the inner wall of the circular hole.
[0039] Working principle: When it is necessary to install an early warning device on the explosion-proof high-pressure hose, the staff will sleeve the arc plate A21, the arc plate B22, the arc plate C23 and the arc plate D24 on the joint of the hose body 1, and then insert the plug 31 into the inner wall of the arc plate C23, so that the wedge block 32 is engaged with the slot under the elastic force of the compression spring 33, and at the same time, the arc plate C23 and the arc plate D24 are limited, so that the elastic component 2 is installed on the hose body 1.
[0040] When the joint of the hose body 1 is expanded by high pressure, the arc plate A21, the arc plate B22, the arc plate C23 and the arc plate D24 are squeezed, so that the arc plate C23 and the arc plate D24 slide upward along the outer circumference of the two groups of guide rods 25 respectively, and the arc plate A21 and the arc plate B22 slide downward along the outer circumference of the two groups of cylindrical rods 27 respectively, and the button 282 set on the block 281 is squeezed by the arc plate A21 and the arc plate B22, and the warning light 283 is controlled to turn on by the button 282, so that the warning light generated by the warning light 283 can remind the surrounding staff to check, thereby achieving an explosion-proof warning effect.
[0041] When the staff needs to adjust the warning range according to the compressive strength of the hose body 1, the staff pulls the pull rod 284 outward to release the block 286 from the plug-in effect with the circular hole and releases the limiting effect on the block 281, and slides the block 281 along the outer wall of the cylindrical rod 27 to adjust the position of the button 282 to adjust the warning range. When it is adjusted to the specified position, the staff loosens the pull rod 284 to make the block 286 engage with the circular hole under the elastic force of the limiting spring 285 and limit the block 281 to keep the button 282 fixed. When the warning device needs to be disassembled, the staff presses the wedge block 32 to release the wedge block 32 from the clamping effect with the slot, thereby releasing the limiting effect on the arc plate C23 and the arc plate D24, which is convenient for disassembly of the warning device.
[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
