Description

Technical Field

[0001] This utility model relates to the field of bellows device technology, specifically a bellows connector assembly. Background Technology

[0002] A bellows is a tubular elastic sensing element made of foldable corrugated sheets connected along the folding and stretching direction. Bellows are widely used in instrumentation, primarily as measuring elements in pressure gauges, converting pressure into displacement or force. Bellows have thin walls, high sensitivity, and a measuring range from tens of Pascals to tens of megapascals. Its open end is fixed, while the sealed end is in a free state, with auxiliary helical springs or leaf springs used to increase elasticity. During operation, under internal pressure, it stretches along the length of the tube, causing the movable end to produce a displacement proportional to the pressure. The movable end drives a pointer to directly indicate the pressure magnitude. Bellows are often combined with displacement sensors to form pressure sensors that output electrical signals; they are also sometimes used as isolation elements.

[0003] Currently, the existing connector adopts a rotary double-joint interlocking structure, which can realize the replacement of the connector as needed, effectively solving the limitation problem of bellows connection. This connector adopts the connector butt joint method, and when the connector is damaged, the connector can be directly replaced.

[0004] For example, the waterproof stainless steel corrugated pipe connector disclosed in patent announcement number CN212509969U includes a pipe body port, a connecting end, and a connecting sleeve. One end of the pipe body port is sealed and fixed to the corrugated pipe, and the other end is threadedly connected to the connecting end. The connecting end is fitted into the end connecting sleeves on both sides of the connecting frame plate. The connecting end includes a top end and a bottom end, which are respectively fitted into the top and bottom of the end connecting sleeve. The top end is threadedly connected to the outer pipe, and the bottom end is threadedly connected to the connecting end. A carrier plate is provided on the connecting end, and the carrier plate corresponds to the position of the connecting frame plate. An expansion joint is provided between the carrier plate and the connecting frame. However, with such a waterproof stainless steel corrugated pipe connector, it is inconvenient to connect and install different types of drain pipes, and when the pipe body port is threadedly connected to the connecting port, it is necessary to operate and check the connection and installation, which is inconvenient for the operator to install quickly.

[0005] As can be seen from the solutions disclosed in the existing patent documents, corrugated pipes are inconvenient for connecting and installing different types of drain pipes. Furthermore, when connecting the threaded ports of the pipe body, it is necessary to operate and inspect the connection and installation, which is inconvenient for operators to install quickly. Therefore, it is necessary to improve the existing technology. Utility Model Content

[0008] Preferably, the corrugated pipe is internally fitted with a drain pipe, and the buffer ring is internally fitted with a connecting pipe. By rotating the tightening bolt, the clamping ring can be driven to contract, thereby causing the connecting pipe to clamp different types of drain pipes, thus expanding the range of applications.

[0009] Preferably, a guide plate is slidably sleeved inside one end of the connecting tube, and the upper end of the guide plate slides tightly against the limiting ring. The design of the guide plate can guide the connecting tube to retract and move, preventing lateral deviation from affecting normal use.

[0010] Preferably, a groove is provided inside one end of the connecting pipe, and a drain pipe is sleeved inside the connecting pipe. The design of the limiting ring can restrict the movement of the clamping ring and effectively prevent the connecting pipe from sagging.

[0011] Preferably, a right fixing block is fixedly welded to one end of the clamping ring, a nut is tightly attached to one side of the right fixing block, and the lower end face of the limiting ring is tightly attached to the right fixing block. By rotating the actuating plate, the bolt threadedly connects to the nut, causing the buffer ring to squeeze the connecting pipe onto the drain pipe, which facilitates quick installation of the connecting pipe and the corrugated pipe.

[0012] Preferably, the lower end face of the limiting ring is in close contact with the buffer ring, and the lower end face of the limiting ring is in close contact with the left fixing block. The design of the buffer ring can buffer the squeezing of the connecting pipe by the clamping ring, effectively preventing the clamping ring from squeezing and damaging the connecting pipe.

[0013] Preferably, the clamping ring and the buffer ring have slots inside, the left fixing block has a bolt inside, one end of the bolt is fixedly welded to a toggle plate, the other end of the bolt is connected to a nut by a thread, and the right fixing block is sleeved on the outside of the bolt. The design of the toggle plate allows the operator to easily rotate the bolt in dim lighting, without installation tools, or when it is inconvenient to see the installation operation, thus improving ease of use.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model can cause the clamping ring to retract by rotating the tightening bolt, thereby causing the connecting pipe to clamp different models of drain pipes, expanding the scope of application. The guide plate design can guide the retraction and movement of the connecting pipe to prevent lateral deviation from affecting normal use. The limit ring design can restrict the movement position of the clamping ring, effectively preventing the connecting pipe from sagging.

[0016] 2. This utility model uses a rotating actuating plate to drive the bolt threaded connection nut, which in turn drives the buffer ring to squeeze the connecting pipe onto the drain pipe, facilitating quick and easy installation of the connecting pipe and corrugated pipe. The buffer ring design can buffer the squeezing of the connecting pipe by the clamping ring, effectively preventing the clamping ring from squeezing and damaging the connecting pipe. The actuating plate design allows the operator to easily rotate the bolt in dim lighting, without installation tools, or when it is inconvenient to see the installation operation, thus improving ease of use.
