Description

Technical Field

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

[0002] As a key pipe connection element, right-angle corrugated pipes play an indispensable role in the building, HVAC, and industrial fields due to their unique pre-formed right-angle structure and flexible characteristics. They can provide a precise and efficient 90-degree turning solution for fluid, gas, and cable protection in compact or structurally complex confined spaces. Furthermore, they can significantly improve the overall performance of piping systems and the fault tolerance of engineering installations by compensating for installation errors and absorbing vibration and noise.

[0003] Existing technologies also have the following shortcomings: Current right-angle corrugated pipes typically lack dedicated quick-connect structures, relying on on-site manual bending and additional clamps for fixation, making it difficult to guarantee bending accuracy and prone to springback and loosening; pipe connections often use adhesive or ordinary strapping, resulting in poor sealing and pull-out resistance, and cumbersome and time-consuming operations. Furthermore, the overall lack of an integrated fixing design requires external supports and complex tools for positioning, leading to low installation efficiency, poor stability, and difficulty in meeting the demands of efficient construction. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a right-angle corrugated pipe that is easy to install, thus solving the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a right-angle corrugated pipe that is easy to install, comprising: a right-angle corrugated pipe, a fastening collar fixedly connected to the right-angle corrugated pipe, a fixing seat fixedly connected to the fastening collar, through holes on both sides of the fastening collar, a locking hoop slidably connected in the through holes, and holes on both sides of the locking hoop; The fixed base is threaded with bolts, which are threaded into holes on both sides of the locking hoop. Nuts are fixedly connected to both sides of the bottom of the locking hoop. Internal threaded holes are opened on both sides of the fastening sleeve. External threaded sleeves are fixedly connected to the right-angle corrugated pipe, and quick-connection mechanisms are provided on the external threaded sleeves.

[0006] As a further embodiment of this utility model: the quick connection mechanism includes: an internal threaded sleeve and a straight corrugated pipe, wherein the internal threaded sleeve is threadedly connected to the external threaded sleeve.

[0007] As a further embodiment of this utility model, a limiting collar is fixedly connected to the external threaded sleeve.

[0008] As a further embodiment of this utility model: a barb is provided at the top of the internal threaded sleeve.

[0009] As a further embodiment of this utility model: a rubber sealing ring is fixedly connected inside the external threaded sleeve, and an elastic clamp is provided inside the external threaded sleeve.

[0010] As a further embodiment of this utility model: the elastic clamp has multiple corrugations in its internal fixed connection.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, by setting up a quick-locking mechanism, utilizes the coordinated cooperation between the elastic clamp and the internal and external threaded sleeves, and the corrugated pattern on the elastic clamp, allows the elastic clamp to be locked simply by inserting and rotating the internal threaded sleeve during connection. This ensures that the straight corrugated tube inside the elastic clamp is firmly locked inside the right-angle corrugated tube. Furthermore, by setting a fixing device on the outside of the right-angle corrugated tube, the corrugated tube can be stably fixed in the designated position under the action of the locking clamp and the fastening collar, achieving the dual effect of convenient installation and connection.

[0014] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0015] like Figures 1-6 As shown, this utility model provides a technical solution: A right-angle corrugated pipe that is easy to install includes: a right-angle corrugated pipe 1, a fastening collar 5 fixedly connected to the right-angle corrugated pipe 1, a fixing seat 51 fixedly connected to the fastening collar 5, through holes on both sides of the fastening collar 5, a locking clamp 53 slidably connected in the through holes, and holes on both sides of the locking clamp 53. Bolts 54 are threaded onto the fixed base 51. Bolts 54 are threaded onto the holes on both sides of the locking clamp 53. Nuts 55 are fixedly connected to both sides of the bottom of the locking clamp 53. Internal threaded holes 56 are opened on both sides of the fastening sleeve 5. External threaded sleeve 2 is fixedly connected to the right-angle corrugated pipe 1. A quick connection mechanism is provided on the external threaded sleeve 2. Specifically, in use, the right-angle corrugated pipe 1 needs to be tightened first. The bolt 54 needs to be turned first. Since the bolt 54 is threaded to the holes on both sides of the locking clamp 53, and since the nuts 55 are fixedly connected to the bottom sides of the locking clamp 53, when the bolt 54 is turned, the locking clamp 53 can be moved upward until the right-angle corrugated pipe 1 is locked. After locking both ends of the right-angle corrugated pipe 1 in this way, the fastening collar 5 is fixed in the designated position through the internal threaded holes 56 on both sides of the fastening collar 5. In this way, the two ends of the right-angle corrugated pipe 1 can be connected. The quick-connect mechanism includes: an internal threaded sleeve 23 and a straight corrugated pipe 4. The internal threaded sleeve 23 is threadedly connected to the external threaded sleeve 2. A limit collar 3 is fixedly connected to the external threaded sleeve 2. A barb 24 is provided at the top of the internal threaded sleeve 23. A rubber sealing ring 21 is fixedly connected inside the external threaded sleeve 2. An elastic clamp 22 is provided inside the external threaded sleeve 2. Multiple corrugations 25 are fixedly connected inside the elastic clamp 22. Specifically, after fixing the right-angle corrugated pipe 1, first rotate the internal threaded sleeve 23 to loosen the elastic clamp 22. Then, insert the straight corrugated pipe 4, which needs to be connected to the right-angle corrugated pipe 1, into the external threaded sleeve 2. When the bottom touches the rubber sealing ring 21, it can be fixed. At this time, rotate the internal threaded sleeve 23 in the opposite direction to allow it to move downward. Since the end of the elastic clamp 22 is chamfered, and the inner ring of the external threaded sleeve 2 near the elastic clamp 22 is also chamfered, the barb 24 on the upper part of the internal threaded sleeve 23 can be inserted into the elastic clamp when the internal threaded sleeve 23 moves downward. Between the clamp 22 and the external threaded sleeve 2, the barb 24 can squeeze the elastic clamp 22, so that the squeezed part can move inward. Multiple corrugations 25 are provided on the inner wall of the elastic clamp 22. These corrugations 25 can engage with the straight corrugated pipe 4. Combined with the locking effect of the elastic clamp 22, the fastening effect is further strengthened. Thus, under the action of the quick locking mechanism, the right-angle corrugated pipe 1 and the straight corrugated pipe 4 can be tightly connected. Under the action of the locking clamp 53 and the fastening collar 5, the right-angle corrugated pipe 1 can be stably fixed in the designated position, achieving the dual effect of convenient installation and connection.

[0016] The working principle of this utility model is as follows: First, when using it, the right-angle corrugated pipe 1 needs to be tightened. First, the bolt 54 needs to be turned. Since the bolt 54 is threaded to the holes on both sides of the locking clamp 53, and since the locking clamp 53 is fixedly connected to the bottom two sides, when the bolt 54 is turned, the locking clamp 53 can be moved upward until the right-angle corrugated pipe 1 is locked. After locking both ends of the right-angle corrugated pipe 1 in this way, the fastening collar 5 is fixed in the designated position through the internal threaded holes 56 on both sides of the fastening collar 5. In this way, the two ends of the right-angle corrugated pipe 1 can be connected. Next, after fixing the right-angle corrugated pipe 1, first rotate the internal threaded sleeve 23 to loosen the elastic clamp 22. Then, insert the straight corrugated pipe 4, which needs to be connected to the right-angle corrugated pipe 1, into the external threaded sleeve 2. When the bottom touches the rubber sealing ring 21, it can be fixed. At this time, rotate the internal threaded sleeve 23 in the opposite direction to allow it to move downward. Since the end of the elastic clamp 22 is chamfered, and the inner ring of the external threaded sleeve 2 near the elastic clamp 22 is also chamfered, the barb 24 on the upper part of the internal threaded sleeve 23 can be inserted into the elastic clamp when the internal threaded sleeve 23 moves downward. Between the clamp 22 and the external threaded sleeve 2, the barb 24 can squeeze the elastic clamp 22, so that the squeezed part can move inward. Multiple corrugations 25 are provided on the inner wall of the elastic clamp 22. These corrugations 25 can engage with the straight corrugated pipe 4. Combined with the locking effect of the elastic clamp 22, the fastening effect is further strengthened. Thus, under the action of the quick locking mechanism, the right-angle corrugated pipe 1 and the straight corrugated pipe 4 can be tightly connected. Under the action of the locking clamp 53 and the fastening collar 5, the right-angle corrugated pipe 1 can be stably fixed in the designated position, achieving the dual effect of convenient installation and connection.

[0017] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
