Technical Field

[0001] The utility model relates to the technical field of pipe butt joint, in particular to a bellows port butt joint component. Background Art

[0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the folding and stretching direction. Bellows are widely used in instruments and meters. Their main purpose is to be used as a measuring element of pressure measuring instruments to convert pressure into displacement or force. The bellows has a thinner wall and higher sensitivity. The measuring range is from tens of Pa to tens of MPa. Its open end is fixed, the sealed end is in a free state, and an auxiliary spiral spring or reed is used to increase elasticity.

[0003] In the prior art, when the ends of the bellows are connected, the operator first plugs the ends of the two bellows together, and then uses a simple tie device to tie and fix the two bellows.

[0004] There are two disadvantages in the above process. First, the bellows is not sealed, and the internal sewage will be discharged through the gaps, polluting the soil. Second, the tie-tying device only uses a semicircular ring to fix on the surface of the bellows for tie-tying, which causes uneven force on the bellows and internal displacement. In addition, the tie-tying force needs to be manually adjusted during tie-tying, which is inconvenient to operate. Summary of the invention

[0013] Preferably, the arc-shaped clamping plate is symmetrically arranged on the surface of the corrugated pipe, the arc-shaped clamping plate is fixed by bolts, and the bottom of the arc-shaped clamping plate is hinged to the surface of the fixing block.

[0014] Preferably, a sealing gasket is evenly bonded to the surface of the circular support ring, the circular support ring and the arc-shaped clamping plate are at the same position, the sealing gasket is at the joint of the corrugated pipe, and the surface of the sealing gasket is evenly coated with waterproof glue.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model discloses a bellows port docking component. First, a circular support ring with a sealing gasket is placed in a bellows, and a half of the sealing gasket with waterproof glue is bonded to the bellows. Then, the two bellows are docked. An arc-shaped clamping plate is fixed to the port of the bellows by bolts.
