Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe technology, specifically a right-angle corrugated pipe that is resistant to breakage. Background Technology

[0002] A bellows is an elastic sensitive element formed by connecting foldable corrugated sheets along the folding and stretching direction. Bellows are widely used in instruments and meters, mainly as the detection element of pressure measuring instruments, converting pressure into displacement or force. The bellows has connecting pipes with regular corrugated patterns on the inner and outer walls, which can effectively protect the internal circuitry of the bellows. The significant feature of right-angle bellows is that it has a 90-degree right-angle bending structure.

[0003] In existing technologies, right-angle corrugated pipes, as a common flexible connection component, are widely used in mechanical transmission and vibration isolation systems. However, due to their unique right-angle structure, they are exposed to the external environment for a long time without effective protection, making this part a weak link in the entire corrugated pipe assembly. During use, right-angle corrugated pipes are frequently subjected to bending stress caused by thermal expansion and contraction of the pipeline system and equipment displacement, which easily leads to material fatigue. This causes micro-cracks to appear in the right-angle area of ​​the corrugated pipe. These micro-cracks will continue to expand under continuous stress cycles, eventually developing into cracks that are visible to the naked eye. Once cracks appear, they may cause safety accidents, forcing the entire system to shut down for maintenance. Frequent maintenance increases maintenance costs. Therefore, we propose a fracture-resistant right-angle corrugated pipe. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fracture-resistant right-angle corrugated pipe, comprising a connecting pipe one, a right-angle corrugated pipe body installed on the right side of the connecting pipe one, a connecting pipe two fixedly connected to the bottom of the right-angle corrugated pipe body, a fixing plate fixedly connected to the outside of the connecting pipe one, a fixing ring one fixedly connected to the outside of the fixing plate, a support pipe installed on the right side of the fixing ring one, a fixing ring two fixedly connected to the outside of the support pipe, a limiting plate one installed on the left side inside the fixing ring two, a limiting plate two installed on the right side inside the fixing ring two, multiple limiting grooves one opened on the outside of the limiting plate one, multiple limiting grooves two opened on the outside of the limiting plate two, a connecting rod slidably connected inside the limiting groove one, a fixing block fixedly connected to the outside of the connecting rod, two locking blocks fixedly connected to the outside of the fixing block, a toggle piece fixedly connected to the outside of the limiting plate one, a toggle groove one opened at the top of the outside of the fixing ring two, and a spring-loaded component installed outside the toggle piece.

[0006] The spring-loaded assembly is externally fixedly connected to a connecting piece, and a spring is sleeved on the outside of the spring-loaded assembly. The second fixing ring is externally fixedly connected to an arc-shaped block, and the arc-shaped block has multiple slots on its outside.

[0007] The fixed ring two has a limiting block on its outside, and a sliding groove two is slidably connected inside the limiting block. The top of the sliding groove two is fixedly connected to the bottom of the limiting piece two.

[0008] One side of the spring is fixedly connected to the outside of the rebound assembly, and the other side of the spring is fixedly connected to the outside of the connecting piece.

[0012] This utility model has at least the following beneficial effects:

[0013] In use, this invention uses a fixed ring to pull the support tube to fit over the right angle of the right-angle corrugated pipe body, thus thickening the protection of weak points and effectively dispersing bending stress caused by equipment displacement, preventing the generation and propagation of micro-cracks, and reducing the risk of breakage at the source. During installation, the spring-loaded component is pulled outward to disengage from the slot, and the actuating plate is moved to drive the connecting rod in opposite directions, precisely pushing and limiting the corrugated protrusions on the outside of the right-angle corrugated pipe to ensure a stable fit of the support tube. Then, the spring-loaded component is locked into the slot for fixation. The operation is convenient and the positioning is firm, preventing the support tube from retracting and ensuring long-term protection. At the same time, when the actuating plate slides, the limiting plate rotates synchronously within the fixed ring and slides within the limiting block through the actuating groove, further enhancing the stability and accuracy of the actuation process, avoiding protection failure due to operational deviations, ensuring a reliable connection between the support tube and the right-angle corrugated pipe body, effectively extending the service life of the right-angle corrugated pipe, reducing safety accidents and downtime for maintenance caused by breakage, and lowering maintenance costs.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figures 1 to 5This utility model provides a technical solution: a fracture-resistant right-angle corrugated pipe, including a connecting pipe 1, a right-angle corrugated pipe body 101 installed on the right side of the connecting pipe 1, a connecting pipe 2 102 fixedly connected to the bottom of the right-angle corrugated pipe body 101, a fixing plate 2 fixedly connected to the outside of the connecting pipe 1, a fixing ring 201 fixedly connected to the outside of the fixing plate 2, a support pipe 202 installed on the right side of the fixing ring 201, a fixing ring 203 fixedly connected to the outside of the support pipe 202, a limiting plate 204 installed on the left side inside the fixing ring 203, a limiting plate 205 installed on the right side inside the fixing ring 203, multiple limiting grooves 206 opened on the outside of the limiting plate 204, and multiple limiting grooves 207 opened on the outside of the limiting plate 205. An internal sliding connection is provided with a connecting rod 208, and a fixing block 209 is fixedly connected to the outside of the connecting rod 208. Two locking blocks 2010 are fixedly connected to the outside of the fixing block 209. A toggle piece 2012 is fixedly connected to the outside of the limiting piece 1 204. A toggle groove 2013 is opened at the top of the outside of the fixing ring 203. A spring-loaded component 3 is installed on the outside of the toggle piece 2012. To prevent the right angle of the right-angle corrugated pipe body 101 from breaking, it needs to be reinforced and protected. The operator pulls the fixing ring 203 and pulls it from the connecting pipe 1 1 towards the connecting pipe 2 102, so that the support pipe 202 is fitted onto the right angle of the right-angle corrugated pipe body 101. At this time, the support pipe 202 provides additional mechanical support for the right-angle corrugated pipe body 101 and enhances the structural strength of this area.

[0023] The spring-loaded assembly 3 is externally fixedly connected to a connecting piece 301, and a spring 302 is sleeved on the outside of the spring-loaded assembly 3. An arc-shaped block 303 is externally fixedly connected to the fixing ring 203. Multiple slots 304 are opened on the outside of the arc-shaped block 303. One side of the spring 302 is fixedly connected to the outside of the spring-loaded assembly 3, and the other side of the spring 302 is fixedly connected to the outside of the connecting piece 301. When the operator releases the connecting piece 301, the spring 302 returns to its original state, pulls the spring-loaded assembly 3 back to its original position, and locks it into the slot 304. At this time, the spring-loaded assembly 3 cooperates with the slot 304 to limit and engage the limiting piece 204 and the connecting rod 208, ensuring that the support tube 202 is firmly fixed to the outside of the right-angle corrugated pipe body 101, effectively preventing breakage at the right angle.

[0024] A limiting block 4 is provided on the outside of the fixed ring 203. The limiting block 4 has a sliding groove 401 inside, and the top of the sliding groove 401 is fixedly connected to the bottom of the limiting piece 205. The sliding of the sliding piece 2012 causes the limiting piece 204 to rotate inside the fixed ring 203. At the same time, the limiting piece 205 rotates synchronously and is limited by sliding inside the limiting block 4 through the sliding groove 401.

[0025] The connecting rod 208 is externally slidably connected to the inside of the limiting piece 204, the actuating piece 2012 is externally slidably connected to the inside of the actuating groove 2013, the connecting rod 208 is externally slidably connected to the inside of the limiting groove 207, and two mounting pieces 2011 are externally fixedly connected to the connecting rod 208. The limiting piece 204 is externally rotatably connected to the inside of the fixing ring 203, and the limiting piece 205 is externally rotatably connected to the inside of the fixing ring 203. The rotation of the limiting piece 204 and the limiting piece 205 causes the limiting groove 206 and the limiting groove 207 to guide the connecting rod 208 to move towards each other. The connecting rod 208 drives the fixing block 209 and the locking block 2010 to move towards the corrugated protrusion of the right-angle corrugated pipe body 101. Finally, the locking block 2010 pushes the corrugated protrusion, thereby limiting the support pipe 202.

[0026] The working principle of this utility model is as follows: In order to prevent the right angle of the right-angle corrugated pipe body 101 from breaking, it is necessary to reinforce and protect it from the outside. At this time, it is only necessary to pull the fixing ring 203 and pull it from the connecting pipe 1 to the connecting pipe 202 so that the support pipe 202 is sleeved on the right angle of the right-angle corrugated pipe body 101, thereby thickening the protection.

[0027] To ensure the support tube 202 can be effectively installed outside the right-angle corrugated pipe body 101 and prevent retraction, simply slide the fixing ring 203 to the appropriate position on the right-angle corrugated pipe body 101, grasp the spring-loaded component 3 and pull it outwards. Then, the spring-loaded component 3 slides out from the slot 304. Next, move the actuating piece 2012 so that it slides inside the actuating groove 2013. When the actuating piece 2012 moves, it will drive the connecting rod 208 to move in opposite directions, thereby pushing and limiting the corrugated protrusion on the outside of the right-angle corrugated pipe body 101. Then, release the connecting piece 301 so that the spring 302 pulls the spring-loaded component 3 back, causing the spring-loaded component 3 to slide into the slot 304 for limiting and engaging.

[0028] Example 2

[0029] Please see Figure 4 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that when the actuating piece 2012 slides inside the actuating groove 2013, the limiting piece 205 will rotate synchronously inside the fixing ring 203 and slide inside the limiting block 4 through the actuating groove 401 for effective limiting.
