Description

Technical Field

[0001] The utility model relates to the field of telescopic connectors, in particular to a telescopic connector for a variable frequency water supply pipeline. Background Art

[0002] Pipe expansion joints are also called expansion joints, expansion joints, and compensators. Expansion joints can be axially expanded and contracted within a certain range, and can also overcome the offset caused by different axial connections of pipelines within a certain angle. They can greatly facilitate the installation and disassembly of valves and pipelines. They can be freely expanded and contracted within the allowable expansion amount of the pipeline. Once the maximum expansion amount is exceeded, they act as a limit to ensure the safe operation of the pipeline.

[0003] However, the expansion joints for pipes currently on the market are prone to leakage when adjusting the length. Utility Model Content

[0005] The utility model provides the following technical solutions: a telescopic connector for a variable frequency water supply pipeline, comprising a telescopic connector, the telescopic connector comprising an outer diameter tube and an inner diameter tube, a second joint flange is installed on the outer end of the outer diameter tube, a side end of the outer diameter tube located close to the second joint flange is provided with a reserved groove, a clamping groove is arranged inside the reserved groove, one end of the inner diameter tube is located inside the outer diameter tube and a sliding block is arranged, a sealing gasket is sleeved on the outer side of the sliding block, a bellows is installed on the end of the sliding block, the end of the bellows is located inside the reserved groove and a mounting gasket is arranged, and a clamping gasket is installed on the side surface of the mounting gasket corresponding to the position of the clamping groove.

[0006] As a further solution of the utility model: a compression pad is provided inside the reserved groove on a side away from the clamping gasket, a first joint flange is installed at one end of the inner diameter tube away from the sliding block, and an anti-drop block is installed inside the outer diameter tube on a side away from the second joint flange.

[0007] As a further solution of the utility model: a screw backing plate is installed on the outer side of the outer diameter tube, and a telescopic screw is connected between the screw backing plate and the first joint flange.

[0008] As a further solution of the utility model: the clamping gasket is clamped with the clamping groove, and the bellows is fixedly connected to the sliding block and the mounting gasket.

[0009] As a further solution of the utility model: the sealing gasket and the clamping gasket are both rubber components.

[0010] As a further solution of the utility model: the inner diameter length of the anti-dropping block is smaller than the outer diameter length of the sliding block.

[0011] As a further solution of the utility model: the telescopic screw is meshingly connected with the screw rod pad.

[0012] As a further solution of the utility model: a limiting bolt is installed between the pressing pad and the mounting washer.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] When the inner diameter tube as a whole is pulled outward inside the outer diameter tube, the bellows as a whole is stretched and deformed. The flow path formed between the bellows as a whole and the inner diameter tube can be used to guide the liquid, thereby reducing the possibility of leakage between the outer diameter tube and the inner diameter tube.

[0015] The sliding block and the sealing gasket can play a double insurance role under the sealing effect of the outer diameter tube, thereby ensuring the overall airtightness of the telescopic connector. BRIEF DESCRIPTION OF THE DRAWINGS
