Description

Technical Field

[0001] The utility model relates to the technical field of bellows connectors, in particular to a bellows joint. 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, and their main use is as a measuring element of pressure measuring instruments to convert pressure into displacement or force.

[0003] Corrugated pipes are usually connected by joints, but existing bellows joints usually only have horizontal joints that can only connect straight pipes, and cannot be connected to change the direction of the bellows, so they are not enough. Utility Model Content

[0004] In summary, in order to overcome the deficiencies of the prior art, the utility model provides a bellows joint capable of changing the direction of the bellows.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a corrugated pipe joint, comprising a connecting seat and a connecting cover, the connecting cover and the connecting seat are detachably connected, the connecting seat is provided with a first connecting hole, a connecting block is provided on the side of the connecting seat facing the connecting cover, a second connecting hole is provided between the connecting cover and the connecting block, the second connecting hole is connected to the first connecting hole, the axes of the first connecting hole and the second connecting hole are set at an angle, the end of the connecting cover facing the connecting seat is provided with a connecting strip located on the outside of the first connecting hole, and the connecting seat is provided with a connecting groove adapted to the connecting strip at a position corresponding to the connecting strip.

[0006] With such an arrangement, there will be a half hole in the connecting blocks on the connecting cover and the connecting seat. After the connecting cover and the connecting seat are buckled together, the two half holes will be combined to form a complete hole, which is the second connecting hole. The second connecting hole can be used to connect the bellows. After the connecting cover and the connecting seat are buckled together, the bellows will be clamped by the two half holes to complete the connection. After the connection, the bellows can be connected to the first connecting hole through the second connecting hole, and the axis of the first connecting hole is set at an angle with the axis of the second connecting hole. In this way, the turning connection of the bellows can be realized, and a 90-degree longitudinal connection or other angles can be realized. After the connection, the connecting strip on the connecting cover will be inserted into the connecting groove on the connecting seat to make the connection between the two more stable.

[0007] Furthermore, one end of the connection cover is plugged into the connection seat, and the other end is connected by bolts passing through the two. The plugging direction of the connection cover is arranged parallel to the connection surface between the connection seat and the connection cover.

[0008] With this arrangement, after one end of the connecting cover is inserted into the connecting base, the other end is then connected through bolts. In this way, after the two are connected, one side of the bolted connection obviously cannot be pulled up, and the other side cannot be withdrawn or pulled up because the insertion direction is locked. In this way, fewer bolts can be used to complete the connection, making installation more convenient.

[0009] Furthermore, the connection cover is provided with mounting plates at positions on both sides of the connection block, and the connection seat is provided with mounting grooves adapted thereto at positions corresponding to the mounting plates.

[0010] With such arrangement, the mounting plate can clamp the connecting block on both sides thereof, which is more stable, and after connection, the mounting plate will fit in the mounting groove, which is more stable.

[0011] Furthermore, a mounting slope is provided on the top of the side wall of the mounting groove facing the plugging direction of the connecting cover.

[0012] With this arrangement, during installation, one end of the connecting cover is first inserted into the connecting seat. At this time, the bolt connection end is in a cocked state. At this time, the side of the mounting plate will fit the mounting bevel to achieve a positioning effect. After that, the connecting cover is pressed down and the mounting plate will slide completely into the mounting groove along the bevel of the mounting bevel. After the installation is completely completed, the mounting plate will fit the side wall of the mounting groove to maintain stability.

[0013] Furthermore, a plug-in block is provided at one end of the connection seat facing the connection cover, and the plug-in block is provided with a plug-in hole, which passes through the side of the connection block facing the connection cover, and a mounting plug adapted to the plug-in hole is provided on the side of the connection cover facing the plug-in block.

[0014] In this arrangement, the installation insert on the connection cover will be inserted into the insertion hole of the insertion block, so that the other side of the connection cover can be installed and connected using bolts, and the structure is simple.

[0015] Furthermore, the plug-in block is provided with a positioning groove, and the connection cover is provided with a positioning block adapted thereto at a position corresponding to the positioning groove.

[0016] With such arrangement, when the installation plug is just inserted into the plug-in hole, the position where the connection cover can install the plug-in is in a state where the fulcrum is tilted on one side. At this time, the positioning block will be located in the positioning groove, which plays a guiding role in the position of the connection cover. In this way, when the tilted side of the connection cover is pressed down, it can be ensured that the connecting strip is just inserted into the connecting groove, which makes installation more convenient. The plug-in hole can cooperate with the gap between the installation plug-in to facilitate the movement of the installation plug-in, or the plug-in hole can penetrate the bottom surface of the connecting seat to facilitate the movement of the installation plug-in.

[0017] Furthermore, the outer end of the mounting plug facing the connecting seat is chamfered.

[0018] With such arrangement, when the connection cover is in an inclined state of installation, the inclined surface of the installation insert is pressed against the end surface of the connection seat, which is more stable.

[0019] Furthermore, the connection strip and the connection groove are clearance-fitted.

[0020] With such arrangement, the clearance fit facilitates the installation of the two.

[0021] Furthermore, the connection groove is arranged in the connection block.

[0022] With such arrangement, the connecting block will form the side wall of the connecting groove, and the structure is stable.

[0023] Furthermore, the connection grooves are arranged around the first connection hole on both sides of the second connection hole.

[0024] In this arrangement, the connecting groove is U-shaped and surrounds the first connecting hole, and the connecting surface of the second connecting hole does not need to be provided with a connecting groove and a connecting strip because the corrugated tube is to be inserted.

[0032] With such arrangement, there will be a half hole on both the connecting cover 2 and the connecting block 102 on the connecting seat 1. After the connecting cover 2 and the connecting seat 1 are snap-fitted together, the two half holes will be combined to form a complete hole, which is the second connecting hole 201. The second connecting hole 201 can be used to connect the bellows. After the connecting cover 2 and the connecting seat 1 are snap-fitted together, the bellows will be clamped by the two half holes to complete the connection. After the connection, the bellows can be connected to the first connecting hole 101 through the second connecting hole 201. The axis of the first connecting hole 101 is set at an angle with the axis of the second connecting hole 201. In this way, the turning connection of the bellows can be realized, and a 90-degree longitudinal connection or other angles can be realized.
