Detailed Description
It should be noted that, without conflict, the embodiments of the present invention and features of the embodiments may be combined with each other.
The invention will be described in detail below with reference to the drawings in connection with embodiments.
Example 1
An exhaust pipe joint 530 is shown in fig. 1, and the exhaust pipe joint 530 can be detachably connected with an air outlet of a mobile air conditioner. The exhaust pipe joint 530 is generally annular, defining a joint and equipment connection end as the inner end and the other end as the outer end. The inner wall of the exhaust pipe joint 530 is provided with two sets of screw thread groups 531 for contacting with the folded surface of the air pipe and locking the air pipe. In other embodiments, the number of thread groups 531 may be 1-6, each thread group 531 having the same structure and being circumferentially uniformly distributed on the inner wall of the joint.
As shown in fig. 2, it is an arrangement of a set of threads 531 on the inner wall of the joint, the set of threads 531 comprising two single threads 532 and one double thread 533. The double thread 533 is disposed between two single threads 532, the single threads 532 have one thread rib, and the double thread 533 is composed of two thread ribs. Two ends of two thread ribs of the double thread 533 are connected and mutually close to form a V-shaped structure, and gaps at two ends of the double thread 533 are reduced so that a steel wire ring of the air pipe cannot be inserted between the two thread ribs, and air pipe compression uniformity is guaranteed.
The pitch between each rib in the set of threads 531 is 10-15mm, and the pitch between two ribs of the double thread 533 is 5-6mm. By the aid of the thread structure design, after the exhaust pipe joint 530 is assembled with air pipes of various specifications, the thread group 531 can be in multipoint contact with the folded surface of the air pipe, so that the thread and the folded surface of the air pipe are interfered, and when the air pipe stretches, certain resistance is generated, and the air pipe is not easy to fall off.
The exhaust pipe joint 530 in this embodiment is designed by the thread group 531, so that the joint can be fastened and connected with air pipes of different specifications, and covers air pipes with a pitch of 12-20mm, and has strong universality.
Example 2
In this embodiment, the thread group 531 further includes a counter thread 534, the counter thread 534 is located near the inner end of the joint, and the inclination direction of the counter thread 534 is opposite to the inclination direction of the single thread 532.
The first ring and the second ring of steel wires of the air pipe can be pressed through the reverse threads 534, the steel wire distance is reduced, the outer diameter of the air pipe is increased, the outer diameter of the compressed air pipe is increased by about 0.5mm compared with that of an expanded air pipe, the purpose that the interference quantity is increased between the tail end of the air pipe and the joint 530 of the exhaust pipe can be achieved, the air pipe is locked, and the back-off quantity of the air pipe and the joint during use is reduced.
Example 3
On the basis of the embodiment, two ends of the two thread ribs of the double thread 533 are connected with each other, so that the processing and forming are facilitated. The closed structure at the two ends of the double threads 533 prevents the bead rings of the air pipe from being inserted between the two thread ribs, thereby ensuring the air pipe to be compressed uniformly.
Example 4
On the basis of the embodiment, the interval between each thread rib in the thread group 531 is 12.4mm, and the interval between two thread ribs of the double thread 533 is 5.2mm. After the connector is assembled with air pipes with different specifications, the air pipe folding surfaces are interfered with the connector threads at multiple points, and the three-dimensional simulation interference quantity is about 1mm, so that the interference effect is optimal. When in actual assembly and use, the damping sense is slight, and the tightness of the air pipe is moderate.
Example 5
This embodiment is different from the above embodiment in that the interval between each thread rib in the thread group 531 is 10mm, and the interval between two thread ribs of the double thread 533 is 5mm.
Example 6
This embodiment is different from the above embodiment in that the interval between each thread rib in the thread group 531 is 15mm, and the interval between two thread ribs of the double thread 533 is 6mm.
Example 7
This embodiment is different from the above embodiment in that the interval between each of the ribs in the screw group 531 is 13mm, and the interval between two ribs of the double screw 533 is 5.4mm.
Example 8
This embodiment is different from the above embodiment in that the interval between each of the ribs in the screw group 531 is 11mm, and the interval between two ribs of the double screw 533 is 5.2mm.
Example 9
This embodiment is different from the above embodiment in that the interval between each thread rib in the thread group 531 is 14mm, and the interval between two thread ribs of the double thread 533 is 5.7mm.
Example 10
On the basis of the above embodiment, as shown in fig. 3, the inner end of the exhaust pipe joint 530 is provided with a limiting ring 537 and four positioning folds 538, and a connecting groove is formed between the limiting ring 537 and the positioning folds 538 for fixedly connecting the exhaust pipe joint 530 with an air outlet of the mobile air conditioner.
In other embodiments, there may be 2-6 locating folds 538, which are evenly distributed over the inner end of the fitting.
The inner wall of the joint is also provided with a stop buckle 535 which is used for being matched with the thread group 531 to clamp the air pipe.
Example 11
In this embodiment, as shown in fig. 4, the stop 535 is T-shaped and is disposed near the inner end of the joint. The stop 535 of this shape has a large stop area which cooperates with the counter thread 534 nearest the inner end of the connector to compress the first wire of the air duct and effectively retain the air duct and prevent it from falling off.
The inner wall of the exhaust pipe joint 530 is also provided with an installation pointing mark 536, which is positioned near the outer end of the joint and used for indicating the rotation direction of the joint when the joint is connected with a mobile air conditioner, and the rotation direction of the joint is opposite to that of the equipment connection and the air pipe connection.
One end of the positioning folded edge 538 is provided with a stop 539, and the other end is provided with a positioning notch 5310 for being matched with a connecting structure on an air outlet of the mobile air conditioner to fix the joint on the air outlet.
Example 12
In the present embodiment, as shown in fig. 5, the air discharge pipe joint 530 is mounted in a mobile air conditioner. The installation mode is that the exhaust pipe joint 530 is aligned with the installation position of the air outlet of the mobile air conditioner, the joint is rotated according to the direction indicated by the installation pointing mark 536, and when the joint is rotated to the connection position, the stop 539 and the positioning notch 5310 of the positioning folded edge 538 are in contact with the connection structure on the air outlet, so that the joint is integrally fixed at the air outlet. The removal of the adapter simply requires reverse rotation of the adapter to move the positioning flange 538 away from the fixed position to disengage the exhaust coupler 530 from the mobile air conditioner.
The exhaust pipe joint 530 is arranged on the mobile air conditioner, so that the universality of the mobile air conditioner is improved, and the air pipes with various specifications can be connected with the mobile air conditioner, thereby meeting the actual use requirements.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
