Description

Elastic fastening structure of positive-pressure flexible air pipe
Technical Field
The utility model relates to an tuber pipe technical field especially relates to a malleation flexible air pipe elasticity fastening structure.
Background
The flexible air pipe is made of anticorrosive, airtight and mildew-resistant flexible materials, and has the common point that the flexible air pipe is easy to bulge in a positive pressure state to influence the service life of the flexible air pipe; the common scheme for solving the problem in the prior art is that a rigid reinforcing frame is arranged outside the air pipe under the condition of meeting the reinforcing condition, so that a good fixing effect can be achieved, but the damage of pressure difference to the air pipe is difficult to weaken.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's defect and not enough, provide a malleation flexible air pipe elasticity fastening structure, this malleation flexible air pipe elasticity fastening structure is effectual to have reduced the destruction of pressure differential to the tuber pipe, has prolonged the life of tuber pipe.
In order to achieve the above object, the utility model adopts the following technical scheme: a positive pressure flexible air pipe elastic fastening structure comprises an air pipe, a fixing device and an elastic fastening device; the fixing device comprises a screw, a sealing gasket, a reinforcing gasket and a nut; the screw is provided with a sealing gasket, a reinforcing gasket and a nut in sequence from inside to outside on two sides of the wall of the air pipe; the elastic fastening device comprises a steel pipe, a spring, a bottom plate, a baffle ring and a supporting screw rod; a bottom plate is welded at one end of the screw rod in the air pipe; the screw rod penetrates through the steel pipe, one end of the steel pipe wall protrudes inwards to form a stopper, and a spring is arranged between the bottom plate and the stopper on the outer wall of the screw rod; the spring is welded and fixed with the bottom plate, and a baffle ring is also welded at the other end of the spring; and supporting screws are screwed between the corresponding steel pipes and in the steel pipes.
Preferably, the middle part of the supporting screw is square and is not provided with threads so as to facilitate rotation.
The utility model has the advantages that: its tuber pipe of this flexible tuber pipe elastic fastening structure of malleation passes through fixing device and elastic fastening device and forms the counter-pull effect, and utilizes the characteristic of spring to reach the elastic fastening effect to effectual pressure differential of having reduced is to the destruction of tuber pipe, and then has prolonged the life of tuber pipe.
Drawings
Fig. 1 is a schematic view of an elastic fastening structure of a positive pressure flexible air duct.
Wherein: the device comprises an air pipe 1, a fixing device 2, a screw 21, a sealing gasket 22, a reinforcing gasket 23, a nut 24, an elastic fastening device 3, a steel pipe 31, a spring 32, a bottom plate 33, a retaining ring 34 and a supporting screw 35.
Detailed Description
The present invention will be described in further detail with reference to fig. 1.
As shown in fig. 1, an elastic fastening structure for a positive pressure flexible air duct comprises an air duct 1, a fixing device 2, and an elastic fastening device 3; the fixing device 2 comprises a screw 21, a sealing gasket 22, a reinforcing gasket 23 and a nut 24; the screw 21 is provided with a sealing gasket 22, a reinforcing gasket 23 and a nut 24 in sequence from inside to outside on two sides of the pipe wall of the air pipe 1; the elastic fastening device 3 comprises a steel pipe 31, a spring 32, a bottom plate 33, a baffle ring 34 and a supporting screw 35; a bottom plate 33 is welded at one end of the screw 21 in the air pipe 1; the screw 21 penetrates through the steel pipe 31, one end of the pipe wall of the steel pipe 31 protrudes inwards to form a stopper, and a spring 32 is arranged between the bottom plate 33 and the stopper on the outer wall of the screw 21; the spring 32 is welded and fixed with the bottom plate 33, and a stop ring 34 is also welded at the other end of the spring 32; support screws 35 are screwed between the corresponding steel pipes 31 and into the steel pipes 31.
In specific implementation, the middle of the supporting screw 35 is square and is not provided with threads so as to be convenient for rotation.
The working principle is as follows: when the tuber pipe 1 is in the malleation state, tuber pipe 1 accessible fixing device 2 and elasticity fastener 3 form the counter-pull effect, and utilize the characteristic of spring 32 to reach the elasticity fastening effect to effectual pressure differential that has reduced is to the destruction of tuber pipe 1, and then has prolonged the life of tuber pipe 1.
