Description

Technical Field

[0001] The utility model relates to the technical field of bellows, in particular to a bellows structure with improved axial strength. Background Art

[0002] A bellows is a tubular elastic sensitive element constructed by connecting foldable corrugated sheets along the folding and contracting direction. 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 measuring range of tens of Pa to tens of MPa. The open end is fixed, while the sealed end is free, and an auxiliary coil spring or reed is used to increase its elasticity. During operation, the bellows expands along its length under the influence of internal pressure, causing the movable end to displace in a manner proportional to the pressure. This movable end drives a pointer, directly indicating the pressure level. Bellows are often combined with displacement sensors to form pressure sensors with electrical output, and are sometimes also used as isolation elements. Because bellows require a larger volume change to expand, their response speed is slower than that of Bourdon tubes. Bellows are suitable for measuring low pressures.

[0003] The prior art discloses a bellows structure with application number: 202220251404.8 for improving the axial strength of a bellows, comprising a bellows body, a connector fixedly connected to the outer diameter of the bottom end of the bellows body, a first screw threadedly connected to the front and rear through-holes of the connector, a first sealing gasket fixedly connected to the bottom of the connector, a second sealing gasket fixedly connected to the bottom of the bellows body, a fixing member fixedly connected to the top of the bellows body, and a second screw threadedly connected to the left and right through-holes of the fixing member. In the utility model, the first screw cooperates with the nut to achieve preliminary connection and fixation, and the second screw enters the second threaded hole for further connection and fixation, thereby improving the connection firmness of the bellows. The reinforcing rod is provided in conjunction with multiple reinforcing rings fixedly connected to the outer diameter of the bellows body to increase the axial strength of the bellows body and improve the quality of the bellows. However, the prior art still lacks sufficient heat dissipation performance, and the material strength decreases significantly when the ambient temperature is high, which easily affects its service life. To this end, we propose a bellows structure with improved axial strength to solve the above problems. Utility Model Content
