Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe connection technology, and in particular to an auxiliary fixing device for corrugated pipe connection. Background Technology

[0002] In many engineering fields involving fluid transportation and gas conduction, corrugated pipes have been widely used due to their good flexibility and bendability.

[0003] Currently, common corrugated pipe connection methods mostly employ simple socket joints or ordinary clamps for fixing, but these methods have many drawbacks. First, socket joints are not secure and are prone to loosening and leakage after being subjected to external forces or prolonged use. Second, ordinary clamp fixing is cumbersome, requiring multiple tools, resulting in low installation and disassembly efficiency, and it is difficult to guarantee the sealing and stability of the connection. Moreover, once a problem occurs at the connection, it will not only affect the normal operation of the entire system but may also lead to fluid leakage, causing resource waste and safety hazards.

[0004] Therefore, developing a new type of auxiliary fixation device to overcome the above-mentioned defects is of great practical significance. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose an auxiliary fixing device for the corrugated pipe connection, thereby solving the problems mentioned in the background art.

[0006] To achieve the above technical objectives, the present invention provides an auxiliary fixing device for a corrugated pipe connection, comprising: a connecting seat and a tightening ring arranged coaxially. The connecting seat includes an outer tube and an inner tube, the length of which is greater than the length of the outer tube. The two are fixedly connected by the connecting ring. Clamping rings are provided on both sides of the connecting ring, the clamping rings having the same ring width as the connecting ring. A groove adapted to the protrusion of the corrugated pipe is provided on the inner ring surface of the clamping ring. The tightening ring has an inner diameter equal to the outer diameter of the outer tube and is rotatably mounted thereon. The tightening ring drives the two clamping rings to move closer together and lock.

[0007] Furthermore, the outer cylindrical surface of the outer tube is provided with a positioning ring groove, the positioning ring groove is provided with a ratchet, the tightening ring is provided with a pawl that cooperates with the ratchet, the two ends of the outer tube are provided with guide grooves along its axial direction, and the outer ring surface of the retaining ring is provided with two symmetrical guide posts, the guide posts cooperating with the guide grooves.

[0008] Furthermore, the retaining ring includes two semicircular rings, and the guide post includes two semi-studs and a columnar nut. The semi-studs are disposed at both ends of the semicircular rings, and the columnar nut is threadedly engaged with the studs formed by the two semi-studs.

[0009] Furthermore, the tightening ring has mirror-image tightening grooves at both ends, and a handle fixedly connected to the tightening ring is provided above the pawl.

[0010] Furthermore, sealing rings are provided on both sides of the connecting ring, and the tightening ring is the same length as the outer tube and has detachable baffles at both ends.

[0011] Compared with the prior art, the beneficial effects of this utility model include:

[0012] This invention, by setting a coaxial connecting seat and a tightening ring, utilizes the tightening ring to drive the retaining ring to move closer together and lock, enabling convenient and quick connection of two bellows. The groove on the inner ring surface of the retaining ring matches the protrusion of the bellows, enhancing the stability of the connection. Simultaneously, the engagement of the tightening ring with the ratchet teeth and pawls on the outer tube allows for unidirectional rotation and locking of the tightening ring, preventing loosening of the connection. The sealing rings on both sides of the connecting ring improve the sealing performance of the connection. This device has a simple structure, is easy to operate, effectively solves the problem of difficult bellows connection, improves construction efficiency, reduces labor costs, and has high practical value.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] Reference Figure 1 This utility model provides an auxiliary fixing device for a corrugated pipe connection, including a connecting seat 1 and a tightening ring 2 coaxially arranged. The connecting seat 1 is composed of an outer tube 101 and an inner tube 102, the inner tube 102 being longer than the outer tube 101. The two are fixedly connected by a connecting ring 106. Each side of the connecting ring 106 is provided with a retaining ring 3, the width of which is equal to that of the connecting ring 106. The inner surface of the retaining ring 3 is provided with a groove 303 that matches the protrusion of the corrugated pipe. The inner diameter of the tightening ring 2 is equal to the outer diameter of the outer tube 101 and the length of both. The two ends of the tightening ring 2 are provided with detachable baffles 203, which are rotatably mounted on the outer tube 101.

[0018] Reference Figure 2 In terms of specific structure, the outer cylindrical surface of the outer tube 101 is provided with a positioning ring groove 104, and a ratchet 105 is provided in the positioning ring groove 104. The tightening ring 2 is provided with a pawl 202 that cooperates with the ratchet 105 to realize the unidirectional rotation and locking of the tightening ring 2. The outer tube 101 is also provided with guide grooves 103 along its axial direction at both ends. The retaining ring 3 is composed of two semi-circular rings 301. The two ends of the semi-circular rings 301 are provided with semi-studs 302. The studs spliced ​​by the two semi-studs 302 are threadedly engaged with the columnar nut 403. This design facilitates the installation and disassembly of the retaining ring 3. The columnar nut 403 cooperates with the guide groove 103 to ensure the stability of the retaining ring 3 during movement.

[0019] The tightening ring 2 has mirror-image tightening grooves 201 at both ends. When the tightening ring 2 is rotated, the retaining rings 3 move closer together with the cooperation of the tightening grooves 201 and the guide grooves 103. A handle 203 fixedly connected to the tightening ring 2 is provided above the pawl 202 to facilitate the operator to rotate the tightening ring 2. In addition, sealing rings 5 ​​are provided on both sides of the connecting ring 106 to improve the sealing of the connection.

[0020] In practical applications, firstly, the two bellows 4 to be connected are respectively fitted onto the inner tube 102, and the protrusions of the bellows are engaged in the grooves 303 of the retaining ring 3. After rotating the tightening ring 2 to align one end of the tightening groove 201 with one end of the guide groove 103, the columnar nut 403 is pushed in. Then, by rotating the tightening ring 2 through the handle 203, the tightening groove 201 interacts with the columnar nut 403 on the retaining ring 3, driving the two retaining rings 3 to move closer together, thus tightly connecting the two bellows. Simultaneously, the engagement of the pawl 202 and the ratchet 105 ensures unidirectional rotation and locking of the tightening ring 2, preventing loosening of the connection. When disassembly is required, hold the handle 203 and press the end of the pawl 202, then rotate the tightening ring 2 in the opposite direction to separate the retaining rings 3, allowing the bellows 4 to be easily removed.

[0021] This device is simple in structure and easy to operate, enabling quick and easy connection of two bellows while ensuring a strong and airtight connection. It also features easy disassembly and reusability, making it suitable for various bellows connection scenarios.
