Description

Technical Field

[0001] The invention belongs to the technical field of corrugated pipes, and in particular relates to an anti-corrosion type hollow wall double-layer reinforced corrugated pipe. 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 wall of the bellows is thinner and the sensitivity is higher. 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 the elasticity.

[0003] Nowadays, bellows are ubiquitous in people's lives and are used in a wide range of applications. However, when a longer bellows is needed, improper connection or insufficient sealing at the connection often causes leakage of the items or liquids to be transported in the bellows. Therefore, a bellows with simple and tight connection is needed to solve the problem. Summary of the invention

[0028] Anti-corrosion hollow wall double-layer reinforced corrugated pipe, including:

[0029] A first bellows 1, a second bellows 3 is provided on the lower side of the first bellows 1, and a connecting ring is fixedly connected to the upper end of the second bellows 3 and the lower end of the first bellows 1;

[0030] A plurality of groups of clamping mechanisms, each group of the clamping mechanisms is composed of a placement groove 16, a clamping spring 17, a clamping bead groove, a clamping bead 7 and a clamping groove, the placement groove 16 is provided on the circumferential surface of one of the clamping rings 8, the clamping spring 17 is fixedly connected to the inner wall of the placement groove 16, the clamping bead 7 is fixedly connected to one end of the clamping spring 17, the clamping groove is provided on the upper end of the other clamping ring 8, the clamping bead groove is provided on the inner wall of the clamping groove, the clamping bead 7 is movably clamped in the clamping bead groove, the plurality of groups of clamping mechanisms are provided on the circumferential surfaces of the two clamping rings 8, and the plurality of groups of clamping mechanisms are connected to the clamping rings 8 to realize the connection between the first bellows 1 and the second bellows 3; and

[0031] Multiple sets of fastening mechanisms, each set of fastening mechanisms consists of a fixed block 9, a plug-in block 10, a tightening block 14, two movable grooves 11, an elastic hinge shaft 12 and a fastening block 13. The fixed block 9 is fixedly connected to the circumferential surface of one of the clamping rings 8, the plug-in block 10 is fixedly connected to the lower end of the fixed block 9, the two movable grooves 11 are respectively opened at both ends of the plug-in block 10, the two elastic hinge shafts 12 are respectively fixedly connected between the inner walls of the two sides of the two movable grooves 11, the two fastening blocks 13 are respectively rotatably connected to the circumferential surfaces of the two elastic hinge shafts 12, the tightening block 14 is fixedly connected to the circumferential surface of the other clamping ring 8, the fastening groove 15 is opened on one side of the tightening block 14, and the two fastening blocks 13 are both movably clamped in the fastening groove 15. Multiple sets of fastening mechanisms are all arranged on the circumferential surfaces of the two clamping rings 8, and multiple sets of fastening mechanisms are all connected to the clamping ring 8 to achieve the strengthening of the connection tightness between the first bellows 1 and the bellows block 2.

[0032] In a specific embodiment of the present invention, when it is necessary to connect the second bellows 3 and the first bellows 1, the two clamping rings 8 can be brought close to each other, and the upper clamping ring 8 will be clamped into the stable groove provided in the lower clamping ring 8. At this time, the clamping bead 7 will be squeezed until it pops outward due to the elasticity of the clamping spring 17 and is clamped in the clamping groove. At this time, the preliminary installation of the first bellows 1 and the second bellows 3 is completed. At the same time of installation, the plug-in block 10 can be clamped into the fastening groove 15 provided in the tightening block 14. When the lower end touches the inner wall of the fastening groove 15, the elasticity of the elastic hinge shaft 12 will push the fastening block 13 downward and snap the fastening block 13 onto the inner wall of the fastening groove 15. At this time, the second step of snapping, that is, fastening, is completed. Such a design makes the connection between the first bellows 1 and the second bellows 3 simpler, and the two-step snapping, one-step-one-tightening approach also makes the connection between the first bellows 1 and the second bellows 3 closer, preventing the leakage of the items or liquids to be transported therein, thereby reducing resource waste and improving the efficiency of the device.

[0033] For details, please refer to Figure 3 A plurality of return springs 6 are fixedly connected to the circumferential surface of the clamping ring 8 , and one end of each of the plurality of return springs 6 is fixedly connected to a return block 5 .

[0034] In this embodiment: when the first bellows 1 and the second bellows 3 need to be disassembled and replaced, the reset block 5 can be pressed to press the raised snap-in bead 7, and the first bellows 1 or the second bellows 3 can be pulled out. At this time, the first bellows 1 and the second bellows 3 can be separated. This design makes the disassembly between the tubes easier.

[0035] For details, please refer to Figure 4 One side of the reset block 5 is fixedly connected with a hand grip ring 4, and the material of the hand grip ring 4 is rubber.

[0036] In the present embodiment, when the reset block 5 needs to be pressed, the plurality of reset blocks 5 can be squeezed simultaneously by holding the grip ring 4, thereby facilitating the disassembly of the first bellows 1 and the second bellows 3, thereby improving the use efficiency of the device.

[0037] For details, please refer to Figure 3 The circumferential surfaces of the first bellows 1 and the second bellows 3 are both integrally formed with bellows blocks 2, and the interiors of the two bellows blocks 2 are hollow structures.

[0038] In the present embodiment: by means of the integrally formed corrugated blocks 2 on the circumferential surfaces of the first bellows 1 and the second bellows 3, the first bellows 1 and the second bellows 3 can maintain a certain degree of bearing capacity when squeezed by external pressure. Such a design can better protect the first bellows 1 and the second bellows 3, thereby increasing their service life.

[0039] The working principle and use process of the present invention are as follows: when it is necessary to connect the first bellows 1 and the second bellows 3 together, the snap-in bead 7 can be snapped into the snap-in groove, thus completing the first step of installation. During installation, the plug-in block 10 can also be snapped into the fastening groove 15 opened in the tightening block 14. When the lower end of the plug-in block 10 touches the inner wall of the fastening groove 15, the elasticity of the elastic hinge shaft 12 will push the fastening block 13 downward and snap the fastening block 13 into the inner wall of the fastening groove 15. At this time, the second step of fastening is completed. Through such a design, the connection between the first bellows 1 and the second bellows 3 can be made closer, preventing the leakage of items or liquids to be transported inside, thereby reducing resource waste and improving the use efficiency of the device.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
