Example 1: easy joint for air conditioner ventilation pipe

The bellows can stretch out and draw back, the inflation, and can be crooked, and simultaneously, the bellows adopts plastic construction more, or thinner metal construction, and intensity is relatively poor, can not bear great centre gripping. Meanwhile, the basic function of the ventilation pipeline can be realized only by fixing and ensuring sealing. This brings high requirements for construction quality. The common mode that has of current bellows connected mode is that clamp connection, cup joint, butt fusion, rubber coating etc. and fixed effect is all not very good, and has higher to workman's operation level requirement. The connection time is also longer, and the operation efficiency is poorer. It is difficult to form a standardized management of the quality of service.

Based on the consideration, the product designed and used by the user makes up the difficulty in operation through structural design, and is convenient to popularize and standardize operation management. The method comprises the following steps:

the following independent components are included: a first liner tube 1, a second liner tube 2 and a large nut 3;

the first liner pipe 1 is of a hard pipe type structure, and a plastic pipe is adopted in the example, so that the first liner pipe is convenient to process and low in cost. The first liner tube 1 is provided with a circle of first grooves 4, a circle of rubber bag 5 is fixed in the first grooves 4, the rubber bag 5 surrounds the first grooves 4 and is fixedly bonded in the first grooves 4, a circle of annular communicated expansion cavities is arranged in the rubber bag 5 along the extension direction of the rubber bag, and gas is filled in the expansion cavities. The bottom surface of the first groove 4 is provided with a mounting hole, and the inner side of the rubber bag 5 is provided with a nozzle for inflation.

The one end that first recess 4 was kept away from to first bushing pipe 1 is equipped with reducing pipe 6, reducing pipe 6's pipe diameter is greater than first bushing pipe 1's pipe diameter, reducing pipe 6's the outer edge of surveying outward extends along and is equipped with round go-between 7.

The diameter of the second liner pipe 2 is the same as that of the first liner pipe 1, and a plastic pipe is adopted in the embodiment and can be sleeved in the reducer pipe 6 to form sleeving connection. The second liner pipe 2 is also provided with a circle of grooves to define as second grooves 8, a circle of rubber bag 5 is also fixed in the second grooves 8, and the inner side of the rubber bag 5 is provided with a nipple which penetrates through the mounting hole of the second grooves 8 and can be inflated in the second liner pipe 2. A circle of second sealing ring 9 (fixed on the second liner tube 2) is arranged at the edge close to the sleeved end of the second liner tube 2 and the reducer tube 6, a disc 13 is arranged on the rear side of the second sealing ring 9 close to the second groove 8, the disc 13 is of a flange structure, the disc 13 is annular, the inner ring of the disc 13 is fixed on the second liner tube 2, the annular end surface of the disc 13 adjacent to the second sealing ring 9 is fixed with a first sealing ring 10, when the second liner tube 2 is sleeved in the reducer tube 6, the second sealing ring 9 is used for pressing the expansion plug on the inner wall of the reducer tube 6 (sealing the outer wall of the second liner tube 2 and the inner wall of the reducer tube 6), the first sealing ring 10 is used for pressing the outer end face of the connecting ring 7 (sealing the outer end face of the connecting ring 7 and the outer end face of the disk 13) by a swelling plug, so that the sleeved first liner tube 1 and the sleeved second liner tube 2 form double-layer sealing.

Big nut 3 includes screwed pipe 11 and pressure disk 12, pressure disk 12 fixes the one end at screwed

pipe

11, 3 covers of big nut are equipped with the external screw thread on the outside of second bushing pipe 2 on the circumference outer wall of go-between 7, 3 go-between 7 screw-thread fit of big nut, oppress on disc 13 to pressure disk 12. Big nut 3 lets first bushing pipe 1 and second bushing pipe 2 compress tightly to be connected, and first bushing pipe 1 passes through rubber bag 5 expansion plug sealed fixed with one section bellows simultaneously, and second bushing pipe 2 passes through rubber bag 5 expansion plug sealed fixed with one section bellows to get up two sections bellows sealing connection through the cooperation of first bushing pipe 1, second bushing pipe 2, big nut 3.

The specific operation method is as follows:

firstly, sleeving a large nut 3 on a second liner tube 2;

respectively inserting the first liner tube 1 into an opening at one end of the corrugated tube, inflating the normal nozzle in the tube to expand the rubber bag 5, pressing the expansion plug on the inner wall of the corrugated tube, and enabling the first liner tube 1 and the corrugated tube to be fixedly connected in a sealing way;

the second liner pipe 2 is fixedly connected with another section of corrugated pipe in a sealing way in the same way;

and (3) sleeving the reducer pipe 6 of the first liner pipe 1 on the second liner pipe 2, and rotating the large nut 3 to enable the screw thread to be screwed on the connecting ring 7, so that the connection is completed.

The operation has the advantages that the connection of the corrugated pipe is modularized, after the liner pipe is sleeved into the corrugated pipe through the rubber bag 5, the liner pipe is expanded to form tensioning fixation and sealing with the inner wall of the sleeved corrugated pipe, the first liner pipe 1 and the second liner pipe 2 are fixed through the large nut 3, and double-layer connection sealing is formed through the first sealing ring 10 and the second sealing ring 9. The corrugated pipe fixing and sealing device does not adopt rigid fixing, has good adaptability to the low tolerance of the corrugated pipe, is reliably and durably fixed with the corrugated pipe, and greatly improves the construction quality and efficiency.

Meanwhile, the product is convenient to process and produce, low in cost and easy to popularize and apply.

Example 2: easy joint for air conditioner ventilation pipe

In order to prevent the rubber from being deformed due to aging and fatigue and affecting the fixing effect, the difference between this example and embodiment 1 is that the rubber bag 5 is expanded by glue filling, such as glass glue, and after being solidified, the rubber bag and the rubber bag 5 form a solid elastic plug ring, so that a better supporting form is maintained in the rubber bag 5, the expansion deformation is small and has certain elasticity, and the supporting firmness of the plug is enhanced.

Without being limited to examples 1 and 2, the rubber bladder 5 may be filled with a liquid such as water or oil to inflate the rubber bladder 5.
