Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0032] like Figures 1 to 8 As shown, a stainless steel corrugated pipe assembly in one embodiment of the present invention includes: a corrugated pipe 1 and a connecting mechanism 2.

[0033] like Figures 1 to 2 As shown, the bellows 1 has a first connector 101 and a second connector 102 rotatably mounted at both ends.

[0034] like Figures 2 to 8 As shown, the connecting mechanism 2 is installed between a pair of corrugated pipes 1. The connecting mechanism 2 includes a connector 201. A first threaded head 202 and a second threaded head 203 are fixed on both sides of the connector 201. The first threaded head 202 and the second threaded head 203 are adapted to and connected to the first connector 101 and the second connector 102, respectively. The connector 201 is connected to the first connector 101 and the second connector 102 through the first threaded head 202 and the second threaded head 203, thereby connecting multiple corrugated pipes 1.

[0035] Secondly, grooves are carved on multiple sides of the connector 201, and a fixed shaft 204 is fixed in each groove. A retaining plate 205 is rotatably mounted on each of the fixed shafts 204. A sliding groove 206 is carved on the retaining plate 205, and the fixed shafts 204 slide within the sliding groove 206. A control head 208 is fixed to the end of each retaining plate 205 away from the sliding groove 206. When the first connector 101 and the second connector 102 are connected to the connector 201, the retaining plate 205 rotates about the fixed shaft 204 as the axis, causing the retaining plate 205 to rotate. 5. The clamping plate 205 is then pushed towards the second connector 102, causing the fixed shaft 204 to move from the outer end to the inner end of the slide groove 206. This causes the clamping plate 205 to adhere to the outer walls of the first connector 101 and the second connector 102, thereby securing multiple clamping plates 205 together on the multiple outer walls of the first connector 101 and the second connector 102, preventing the first connector 101 from rotating and thus preventing the connection from becoming loose.

[0036] like Figure 2 and Figure 7 As shown, the first threaded head 202 and the second threaded head 203 are threadedly connected to the first connector 101 and the second connector 102, respectively. By rotating, the first connector 101 and the second connector 102 can be connected to the connector 201, thus connecting the two sections of the bellows 1.

[0037] like Figures 5 to 8 As shown, limit blocks 207 are fixed on both sides of the groove, and the limit blocks 207 are used to limit the position of the clamping plate 205. Limiting grooves 214 adapted to the limit blocks 207 are carved on both sides of the clamping plate 205. The side wall of the limiting groove 214 is engaged with the limiting block 207, thereby limiting the clamping plate 205. When the clamping plate 205 is moved to the end of the slide 206 away from the control head 208, the clamping plate 205 can rotate around the fixed shaft 204. After the clamping plate 205 is rotated outward by 90 degrees, the side wall of the limiting groove 214 is engaged with the limiting block 207, thereby fixing the position of the clamping plate 205.

[0038] like Figures 4 to 7 As shown, the sides of the multiple control heads 208 are in contact with each other. When the multiple clamping plates 205 are rotated to be in contact with the surfaces of the first connector 101 and the second connector 102, the sidewalls of the multiple control heads 208 are in contact with each other, forming a closed state.

[0039] like Figures 4 to 7As shown, each of the multiple control heads 208 has an arc-shaped groove 209. The multiple arc-shaped grooves 209 are interconnected, and the side walls of the multiple control heads 208 are all fitted together to form a closed state. After the multiple arc-shaped grooves 209 are interconnected, the multiple arc-shaped inserts 210 are connected to each other to form a closed ring.

[0040] like Figures 4 to 7 As shown, an arc-shaped insert rod 210 is slidably arranged in the arc-shaped groove 209. After multiple arc-shaped insert rods 210 are connected end to end to form a closed ring, by driving one or two arc-shaped insert rods 210 to rotate, the remaining arc-shaped insert rods 210 can be driven to rotate together. When multiple arc-shaped insert rods 210 rotate, they are all inserted into the arc-shaped grooves 209 in the adjacent control heads 208, thereby locking the closed state between the multiple control heads 208.

[0041] like Figures 4 to 7 As shown, a locking block 211 is fixed on the arc-shaped insert 210. One end of the locking block 211 is located outside the control head 208. The locking block 211 is used to lock into the locking body 212, preventing the locking plate 205 from sliding back and forth. Multiple locking bodies 212 adapted to the locking block 211 are fixed on 103. After the arc-shaped insert 210 drives the locking block 211 to rotate, the locking block 211 is locked into the locking body 212. Two of the arc-shaped inserts 210 are fixed with push plates 213 outside the control head 208. The push plates 213 are used to drive the arc-shaped insert 210 to rotate.

[0042] Working principle: When two corrugated pipes 1 need to be connected, firstly, the first connector 101 and the second connector 102 are threaded onto the first threaded head 202 and the second threaded head 203 on the connector 201. Then, the clamping plate 205 is rotated around the fixed shaft 204, so that the clamping plate 205 is in contact with the outer wall of the first connector 101. Then, the clamping plate 205 is pushed towards the second connector 102, so that the fixed shaft 204 moves from the outer end of the slide groove 206 to the inner end, so that the clamping plate 205 is in contact with the outer walls of the first connector 101 and the second connector 102. Thus, multiple clamping plates 205 are locked together on multiple outer walls of the first connector 101 and the second connector 102, preventing the first connector 101 from rotating and thus preventing the connection from becoming loose.

[0043] When multiple locking plates 205 rotate to fit against the outer walls of the first connector 101 and the second connector 102, the side walls of multiple control heads 208 fit against each other to form a closed state, and the multiple arc-shaped slide grooves 209 are interconnected. The multiple arc-shaped insert rods 210 are connected end to end to form a closed ring. Then, the push plate 213 drives the arc-shaped insert rods 210 to rotate. When the multiple arc-shaped insert rods 210 rotate, they are inserted into the arc-shaped slide grooves 209 in the adjacent control heads 208, thereby locking the closed state between the multiple control heads 208. At the same time, after the arc-shaped insert rods 210 drive the locking block 211 to rotate, the locking block 211 is locked in the locking body 212, so that the locking plate 205 cannot move back and forth, thereby doubly locking the locking plate 205 and preventing the first connector 101 from rotating.

[0044] When disassembly is required, the push plate 213 drives the arc-shaped insert 210 to rotate, causing one end of the arc-shaped insert 210 to be pulled out from the arc-shaped slide groove 209 in the adjacent control head 208. At the same time, the arc-shaped insert 210 drives the locking block 211 to move out of the locking body 212. Then, the locking plate 205 can be pulled towards the control head 208 through the control head 208, causing the fixing shaft 204 to move from the inner end of the slide groove 206 to the outer end. Finally, the locking plate 205 can be rotated outward by the outer axis of the fixing shaft 204, so that the locking plate 205 is removed from the outer side wall of the first connector 101 and the second connector 102. After the locking plate 205 is rotated outward by ninety degrees, the side wall of the limiting groove 214 is locked on the limiting block 207, thereby fixing the position of the locking plate 205. Then, the first connector 101 and the second connector 102 can be unscrewed from the connector 201 to complete the disassembly.
