Description

Technical Field

[0001] The present application relates to the technical field of bellows, and in particular to a bellows equipped with a quick-release connector. Background Art

[0002] Bellows are tubular elastic sensitive components made of foldable corrugated sheets connected along the folding and expansion directions. Bellows are widely used in instrumentation, primarily as measuring elements in pressure gauges, converting pressure into displacement or force. Bellows have thinner walls and higher sensitivity, with a measurement range of tens of Pa to tens of MPa.

[0003] In the process of connecting the bellows to the pipeline, a joint is required for the connection operation. The existing joints are relatively complicated to disassemble and install, and the bellows and the pipeline cannot be connected quickly. In addition, the process of disassembling the bellows and the pipeline is relatively complicated, which reduces the connection efficiency of the device for the bellows and the pipeline. Therefore, we propose a bellows equipped with a quick-release joint to solve the above problems. Utility Model Content

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present application provides a corrugated pipe equipped with a quick-release connector, which has the following beneficial effects:

[0017] The bellows equipped with a quick-release joint fits the outer wall of the pressure plate through the limiting cylinder, thereby completing the limiting operation of the pressure plate, and synchronously drives the support plate to compress the ball through the expansion and contraction of the first spring. The ball and the inner wall of the limiting groove fit tightly together, and then the sliding mechanism is connected to complete the limiting operation of the slide plate and the outer wall of the fixed cylinder. The expansion and contraction of the second spring facilitates the sliding operation of the limiting cylinder on the top end of the pressure plate, and the expansion and contraction of the first spring disengages the ball from the limiting groove, which facilitates the rapid installation and disassembly of the pipeline with the bellows and the fixed cylinder under the connection of the second connecting plate and the slide plate, and facilitates the rapid installation and disassembly of the pipeline and the bellows, thereby improving the convenience and work efficiency of the user and improving practicality.

[0026] See also Figure 1-4One end of the slide plate 14 is connected to the support plate 6 through a sliding mechanism. The sliding mechanism includes a fixed plate 15, which is fixedly mounted on the outer wall of the slide plate 14. A slider 16 is longitudinally mounted on the fixed plate 15 for sliding. The slider 16 is fixedly connected to the outer wall of the support plate 6, and the support plate 6 of the sliding operation is limited and connected by the slider 16. A sealing gasket 17 is fixedly mounted on the inner wall of the pipe 3. The sealing gasket 17 fits tightly with one end of the fixed cylinder 2 and the bellows 1. By installing the sealing gasket 17, the sealing effect of the connection operation between the pipe 3 and the bellows 1 is improved. The bellows with a quick-release joint fits with the outer wall of the pressure plate 9 through the limiting cylinder 10, thereby completing the limiting of the pressure plate 9. The first spring 7 is extended and retracted, thereby synchronously driving the support plate 6 to compress the ball 5. The ball 5 and the inner wall of the limiting groove 4 fit tightly together, and then the sliding mechanism is connected to complete the limiting operation of the slide plate 14 and the outer wall of the fixed cylinder 2. The second spring 12 is extended and retracted, thereby facilitating the sliding operation of the limiting cylinder 10 on the top end of the pressure plate 9. The first spring 7 is extended and retracted, so that the ball 5 is disengaged from the limiting groove 4, thereby facilitating the pipe 3 to be quickly installed and disassembled with the bellows 1 and the fixed cylinder 2 under the connection of the second connecting plate 13 and the slide plate 14, thereby facilitating the rapid installation and disassembly of the pipe 3 and the bellows 1, thereby improving the convenience and work efficiency of the user and improving practicality.

[0027] See also Figure 1 It should also be noted that a plurality of anti-slip strips 18 are fixedly installed on the top of the limit cylinder 10. By installing the anti-slip strips 18, it is convenient for the user to slide the limit cylinder 10. Each anti-slip strip 18 is coated with anti-slip paint. By coating the anti-slip paint, the convenience of the user in using the anti-slip strips 18 is improved.

[0028] The outer wall of the sealing gasket 17 is coated with anti-skid paint, which improves the sealing effect when the sealing gasket 17 is connected to the bellows 1 and the fixed cylinder 2.

[0029] When the first spring 7 is extended and the second spring 12 is extended, the first connecting plate 11 and the limiting cylinder 10 are moved laterally, and the limiting cylinder 10 is moved laterally by the first spring 7 and the second spring 12 is extended and the second connecting plate 11 and the limiting cylinder 10 are moved laterally, and the limiting cylinder 10 is contacted with the pressure plate 9 to limit the pressure plate 9. When the pressure plate 9 moves, the top plate 8, the pressure plate 9 and the supporting plate 6 are compressed to make the ball 5 stably fixed in the limiting groove 4, thereby completing the fixing operation of the bellows 1 and the pipe 3. When the bellows 1 and the pipe 3 need to be disassembled, the above operation process can be reversed.
