Technical Field

[0001] This utility model is specifically a flexible connection device for overhead steam pipelines, belonging to the field of steam pipeline technology. Background Technology

[0002] Steam pipelines are a type of pressure pipeline, which in turn are a type of heat pipeline. They are mainly used for heating, ventilation, air conditioning, and industrial gas. There are many aspects to consider when connecting steam pipelines. Some steam pipelines need to be supported and elevated during installation. Chinese Patent Publication No. CN222479772U discloses a steam pipe connection structure, including a connection mechanism. A support mechanism is movably connected to the outer wall of the connection mechanism. The connection mechanism includes a first connecting pipe, a first flange fixedly connected to the outer wall of the first connecting pipe, a set of first holes opened on the outer wall of the first flange, a rubber ring movably connected to one side of the outer wall of the first flange, and a second connecting pipe movably inserted into the inner wall of the first connecting pipe. In this application, with the cooperation of the connection mechanism, when the device is in use, the rubber ring is movably fitted onto the outer wall of the second connecting pipe, and then the second connecting pipe is movably inserted into the inside of the first connecting pipe. However, the aforementioned patent requires connecting two pipes using a first flange and a second flange, followed by bolts through two sets of holes. This installation method requires each pipe to be connected individually, which is cumbersome and time-consuming, reducing efficiency, practicality, and inconvenience. Utility Model Content

[0003] The purpose of this utility model is to provide a flexible connection device for overhead steam pipelines to solve the above-mentioned problems. This solves the problem that in the prior art, after connecting two pipelines by first flange and second flange, the connection and installation are carried out by bolts through two sets of holes. This connection method requires one operation at a time, which is cumbersome.

[0004] This utility model is achieved through the following technical solution: a flexible connection device for an overhead steam pipe, comprising a metal corrugated pipe, with a first connecting plate fixed at both ends of the metal corrugated pipe, a steam pipe provided at both ends of the metal corrugated pipe, a second connecting plate fixed at the end of the steam pipe, a sealing gasket connected between the first connecting plate and the second connecting plate, a connecting mechanism symmetrically arranged on the outer side of the metal corrugated pipe, and a limit mechanism arranged on the outer side of the first connecting plate and the second connecting plate.

[0005] Preferably, the connecting mechanism includes symmetrically opened insertion holes on one side of the first connecting plate and the second connecting plate, a threaded tube symmetrically rotates on the outer side of the metal corrugated tube, a knob is fixed on the outer side wall of the threaded tube, a connecting plate is screwed onto the outer side wall of the threaded tube, an L-shaped plate is symmetrically fixed on the outer side wall of the connecting plate, and an insertion rod is fixed on one side of the L-shaped plate.

[0006] Preferably, the connecting mechanism further includes baffles symmetrically fixed to the outer wall of the metal bellows, and limit rods symmetrically fixed to one side of the second connecting plate.

[0007] Preferably, the outer wall of the knob is provided with anti-slip texture to prevent slippage, and the connecting plate slides on the outer wall of the limiting rod to limit the position of the connecting plate.

[0008] Preferably, the diameter of the insertion rod is equal to the diameter of the insertion hole, so that the insertion rod and the insertion hole fit together.

[0009] Preferably, the limiting mechanism includes mounting covers symmetrically connected to the outer sides of the first connecting plate and the second connecting plate. A connecting block is symmetrically fixed to the outer side wall of one mounting cover, and a slot is provided through the top of the connecting block. An L-shaped rod is symmetrically fixed to the outer side wall of the other mounting cover. A contraction cavity is provided at the top of one side wall of the L-shaped rod. A return spring is fixed to the middle of one side of the contraction cavity. A moving plate is fixed to one end of the return spring, and a locking block is fixed to the middle of one side of the moving plate.

[0010] Preferably, the length and width of the top end of the L-shaped rod are equal to the length and width of the slot opening, so that the L-shaped rod and the slot can be matched. The top of the locking block is provided with an inclined surface, which facilitates the pressing of the inclined surface to move the locking block. The moving plate slides inside the contraction cavity, and the outer side wall of the moving plate is in contact with the inner side wall of the contraction cavity, so that the moving plate can move stably.

[0011] This utility model provides a flexible connection device for overhead steam pipelines, which has the following beneficial effects: This application, through the setting of the connecting mechanism, places the first and second connecting plates against the sealing gasket, aligning the insertion holes. Turning the knob drives the threaded tube to rotate, causing the connecting plate to slide outside the limiting rod, moving the L-shaped plate, thereby moving the insertion rod and inserting it into the insertion hole. At the same time, the L-shaped plate presses against the second connecting plate, making the first and second connecting plates tightly connected. This makes the connection faster and simpler, avoiding the need to tighten bolts one by one, saving time, improving the convenience of connection, and enhancing the practicality of the device.

[0012] This application, through the setting of a limiting mechanism, places two mounting covers outside the first and second connecting plates, allowing the L-shaped rod to be inserted into the slot, thereby squeezing the inclined surface of the locking block, causing the locking block to retract into the contraction cavity, driving the moving plate to move, squeezing the return spring. When the locking block moves out of the slot, the return spring resets the locking block, thereby moving the locking block to the top of the connecting block, thus preventing the L-shaped rod from retracting, connecting the two mounting covers, and ensuring a stable connection between the first and second connecting plates, preventing loosening and improving the stability of the connection.

[0015] This utility model provides a flexible connection device for overhead steam pipelines.

[0016] Please see Figure 1 and Figure 2 The device includes a metal bellows 1, with a first connecting plate 101 fixed at both ends of the metal bellows 1, a steam pipe 2 provided at both ends of the metal bellows 1, a second connecting plate 201 fixed at the end of the steam pipe 2, a sealing gasket 3 connecting the first connecting plate 101 and the second connecting plate 201, a connecting mechanism 4 symmetrically provided on the outer side of the metal bellows 1, and a limit mechanism 5 provided on the outer side of the first connecting plate 101 and the second connecting plate 201.

[0017] Please refer to it again. Figure 2 and Figure 3 The connecting mechanism 4 includes symmetrically arranged insertion holes 401 on one side of the first connecting plate 101 and the second connecting plate 201. A threaded tube 402 is symmetrically rotated on the outer side of the metal bellows 1. A knob 403 is fixed to the outer side wall of the threaded tube 402. A connecting plate 404 is screwed to the outer side wall of the threaded tube 402. An L-shaped plate 405 is symmetrically fixed to the outer side wall of the connecting plate 404. An insertion rod 406 is fixed to one side of the L-shaped plate 405. The connecting mechanism 4 also includes baffles 407 symmetrically fixed to the outer side wall of the metal bellows 1. A limit rod 408 is symmetrically fixed to one side of the second connecting plate 201. The outer side wall of the knob 403 is provided with anti-slip texture, and the connecting plate 404 slides on the outer side wall of the limit rod 408. The diameter of rod 406 is equal to the diameter of insertion hole 401. Through the setting of connecting mechanism 4, the first connecting plate 101 and the second connecting plate 201 are attached to the sealing gasket 3, so that insertion hole 401 is aligned. Rotating knob 403 drives threaded tube 402 to rotate, thereby causing connecting plate 404 to slide outside of limiting rod 408, driving L-shaped plate 405 to move, thereby moving insertion rod 406 and inserting insertion rod 406 into insertion hole 401. At the same time, L-shaped plate 405 presses against second connecting plate 201, so that first connecting plate 101 and second connecting plate 201 are tightly connected, thereby making the connection faster and simpler, avoiding tightening bolts one by one, saving time, improving the convenience of connection, and improving the practicality of the device.

[0018] Please refer to it again. Figure 4 and Figure 5The limiting mechanism 5 includes mounting covers 501 symmetrically connected to the outer sides of the first connecting plate 101 and the second connecting plate 201. A connecting block 502 is symmetrically fixed to the outer wall of one mounting cover 501, and a slot 503 is provided through the top of the connecting block 502. An L-shaped rod 504 is symmetrically fixed to the outer wall of the other mounting cover 501. A contraction cavity 505 is provided at the top of one side wall of the L-shaped rod 504. A return spring 506 is fixed to the middle of one side of the contraction cavity 505. A moving plate 507 is fixed to one end of the return spring 506, and a locking block 508 is fixed to the middle of one side of the moving plate 507. The length and width of the top end of the L-shaped rod 504 are equal to the length and width of the slot 503. The top of the locking block 508 is provided with an inclined surface. The moving plate 507 slides inside the contraction cavity 505, and the moving plate 507... The outer wall of 07 is in contact with the inner wall of the contraction cavity 505. Through the setting of the limiting mechanism 5, the two mounting covers 501 are placed outside the first connecting plate 101 and the second connecting plate 201, so that the L-shaped rod 504 is inserted into the slot 503, thereby squeezing the inclined surface of the locking block 508, causing the locking block 508 to retract into the contraction cavity 505, driving the moving plate 507 to move, squeezing the return spring 506. When the locking block 508 moves out of the slot 503, the locking block 508 is reset by the reset spring 506, thereby moving the locking block 508 to the top of the connecting block 502, thereby preventing the L-shaped rod 504 from retracting, connecting the two mounting covers 501, and stably connecting the first connecting plate 101 and the second connecting plate 201, avoiding loosening and improving the stability of the connection.

[0019] When using this utility model: Working principle: During connection, the first connecting plate 101 and the second connecting plate 201 are placed against the sealing gasket 3 to align the insertion hole 401. Rotating the knob 403 rotates the threaded tube 402, causing the connecting plate 404 to slide outside the limiting rod 408. This moves the L-shaped plate 405, causing the insertion rod 406 to move and insert into the insertion hole 401. Simultaneously, the L-shaped plate 405 presses against the second connecting plate 201, ensuring a tight connection between the first connecting plate 101 and the second connecting plate 201, thus completing the connection. Afterwards, the two mounting covers 501 are placed on the first connecting plate 101. 01 and the outer side of the second connecting plate 201 allow the L-shaped rod 504 to be inserted into the slot 503, thereby pressing the inclined surface of the locking block 508, causing the locking block 508 to retract into the shrinkage cavity 505, driving the moving plate 507 to move, and pressing the return spring 506. When the locking block 508 moves out of the slot 503, the return spring 506 resets the locking block 508, thereby moving the locking block 508 to the top of the connecting block 502, thereby preventing the L-shaped rod 504 from retracting, connecting the two mounting covers 501, and stably connecting the first connecting plate 101 and the second connecting plate 201.
