[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Example

[0034] Reference Figure 1-3 The utility model provides an embodiment: a quick-release flange cover, including a flange outer cover 14, the flange outer cover 14 includes an upper cover shell 1 and a lower cover shell 4, the upper cover shell 1 and the lower cover shell 4 are connected by two spring buckles 5, one side of the flange outer cover 14 is connected with an outer sleeve thread joint 6, and the other side of the flange outer cover 14 is connected with a No. 1 flange 2;

[0035] One side of the No. 1 flange 2 is connected to the No. 2 flange 11 through a plurality of connecting bolts 10 , an end interface 9 is provided at the midpoint of one side of the upper cover shell 1 and the lower cover shell 4 , and a flange adapter 12 is embedded in the flange outer cover 14 .

[0036] Specifically, according to the above-mentioned embodiment, since the inner cavity 8 is provided inside the upper cover shell 1 and the lower cover shell 4, and the flange adapter 12 is embedded in the inner cavity 8, it can be known that when it is necessary to disassemble and replace the damaged parts installed on the flange outer cover 14, it is only necessary to disengage the spring buckle 5 from the clamping state, that is, the two spring buckles 5 include a hook and a spring buckle, and the two hooks and the spring buckle are respectively arranged at the midpoint of the front and rear ends of the upper cover shell 1 and the lower cover shell 4. It can be known that the upper cover shell 1 and the lower cover shell 4 can be separated after the hook and the spring buckle are separated, so that the flange adapter 12 arranged inside, the outer sleeve tooth joint 6 clamped at both ends, and the connected and installed flange can be quickly disassembled and replaced, which solves the disadvantage that the damaged parts of the traditional one-piece flange cover cannot be disassembled separately and need to be replaced as a whole;

[0037] Specifically, according to the above implementation, one end of the flange adapter 12 is connected to the outer sleeve thread joint 6, and the other end of the flange adapter 12 is connected to the No. 2 flange 11. It can be seen that the flange adapter 12 and the No. 2 flange 11 can be disassembled and replaced, and the No. 2 flange 11 and the No. 1 flange 2 can also be disassembled and replaced separately, that is, all accessories can be quickly replaced, and the versatility is stronger.

[0038] Specifically, according to the above embodiment, a connecting pipe 3 is fixedly provided at the midpoint of one side of the No. 1 flange 2, an outer sleeve 7 is clamped on one end of the outer sleeve thread joint 6 away from the outer sleeve thread joint 6, and an inner tube 13 is embedded inside the outer sleeve 7. It can be seen that when the No. 1 flange 2 is disassembled, the connecting pipe 3 is also disassembled together, and the outer sleeve thread joint 6 has the characteristic of being removable from the flange cover 14, so it can be quickly replaced and used according to the model of the outer sleeve 7.

[0039] Specifically, according to the above embodiment, the upper cover shell 1 and the lower cover shell 4 are both made of PVC sheets, that is, according to the characteristics of the PVC sheets themselves, the bending coefficient of the sheets is obtained through repeated tests, and the relevant bending process parameters of the PVC sheets are designed according to the bending coefficient, and the relevant drawings are designed, the sheets are engraved, and the bending and welding are carried out.

[0040] Working principle: When using the flange cover, select outer sleeve thread joints 6 of different calibers according to the specifications and models of the outer sleeve 7, and then clamp it on one side of the lower cover shell 4 and connect it with the outer sleeve 7. Then connect the flange adapter 12 in the inner cavity 8 of the lower cover shell 4 to the other end of the outer sleeve thread joint 6, and then combine the flange composed of the No. 1 flange 2 and the No. 2 flange 11 with the other end of the flange adapter 12, and then use the spring buckle 5 to complete the clamping combination of the upper cover shell 1 and the lower cover shell 4.

[0041] 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. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
