Description

Technical Field

[0001] The utility model relates to the technical field of pipeline fixing, in particular to a trachea connection fixing mechanism. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, the fluid is pressurized by blowers, compressors, pumps and boilers, and flows from the high-pressure part of the pipeline to the low-pressure part. It can also be conveyed by the fluid's own pressure or gravity. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations. When connecting the pipelines, the joints need to be fixed to ensure the stability of the connection, so a supporting and fixing mechanism is needed.

[0003] The Chinese patent with announcement number CN221780147U is a support and fixing mechanism for use at pipeline connections, which belongs to the field of pipeline connections and includes a fixing plate, the top of the fixing plate is fixedly connected to a support seat, the left side of the bottom of the inner cavity of the support seat is fixedly connected to a cylinder, the top of the cylinder is fixedly connected to a slide, the right side of the slide is fixedly connected to a sliding sleeve, the inner cavity of the sliding sleeve is provided with a sliding rod, the right side of the sliding sleeve is fixedly connected to a push plate, and the top of the push plate is fixedly installed with a push rod.

[0004] In the above scheme, the movement of the support frame drives the movement of the C-shaped limit ring and the rubber pad, which is convenient for fixing the pipeline and improves the stability of the pipeline connection. However, it has the following disadvantages: when the limit fixing mechanism of this device fixes the pipeline connection, since the outer wall of the limit ring only fixes one support frame, when fixing the pipeline, the forces generated on both sides of the limit ring are different, which makes the connection easy to fall off, thereby reducing the fixing effect of the fixing mechanism. Utility Model Content

[0005] The purpose of the utility model is to provide a trachea connection fixing mechanism to solve the problem that when the limiting fixing mechanism of the device fixes the pipe connection, since only one support frame is fixed on the outer wall of the limiting ring, the forces generated on both sides of the limiting ring are different when fixing the pipe, which makes the connection easy to fall off.

[0006] The lock hole is formed on the top of the fixing plate, and the fixing plate is fixed with a fixing ring on the inner wall of the fixing plate, and the fixing ring is corresponding to the connecting tube.

[0007] Preferably, a second threaded hole is provided through one side of the fixing cylinder, and a plurality of through holes are provided on one side of the extension plate, and the through holes correspond to the second threaded holes. A threaded groove is provided on the inner wall of the accommodating groove, and the threaded groove corresponds to the second threaded hole. The inner wall of the second threaded hole is threadedly connected to a limiting bolt, and the limiting bolt passes through the through hole and is threadedly connected to the threaded groove. The limiting bolt can facilitate the staff to adjust the length of the extension plate according to needs, so that the fixing mechanism can be flexibly adjusted, thereby improving the flexibility of the fixing mechanism.

[0008] Preferably, a rubber pad is fixed to the inner wall of the fixing ring. The flexible material of the rubber pad can prevent the fixing ring from damaging the outer wall of the sleeve when fixing the sleeve, thereby making the fixing ring fit more closely to the outer wall of the sleeve.

[0009] Preferably, a sealing sleeve is fixed to the outer wall of the connecting pipe, which can increase the adaptability of the outer wall of the connecting pipe and prevent damage to the connecting pipe caused by excessive fixation of the fixing mechanism, thereby improving the integrity of the connecting pipe.

[0010] Preferably, a receiving hole is opened on the top surface of the shell, and a pressure gauge is fixed on the top surface of the shell. The sensing end of the pressure gauge passes through the receiving hole and extends into the connecting pipe. The pressure gauge can facilitate the staff to intuitively observe the pressure changes in the connecting pipe, and can effectively prevent the safety hazards caused by excessive or insufficient pressure in the connecting pipe.

[0011] Preferably, two support frames are fixed to the bottom surface of the shell, and a plurality of fixing cones are fixed to the bottom surface of the support frames. The fixing cones can increase the friction between the support frames and the placement surface to prevent the support frames from sliding.

[0012] Preferably, the diameter of the fixing ring is greater than or equal to the diameter of the sealing sleeve.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The cooperation between the fixing tube and the fixing ring can limit and fix the connection of the connecting pipe, effectively preventing the sleeve from falling off due to pressure after the connection is fixed, thereby ensuring the working efficiency of the connecting pipe and the fixing mechanism. The limiting bolt can facilitate the staff to limit and fix the fixing tube, effectively preventing the fixing tube from sliding due to external force after the fixing ring is fixed to the connection, thereby improving the stability of the connection;

[0015] Second, the rubber pad can increase the friction between the fixing ring and the sleeve, preventing the sleeve from falling off after being connected to the connecting pipe, thereby ensuring the working efficiency of the connecting pipe and the sleeve. The sealing sleeve can increase the sealing of the connecting pipe connection, making the sleeve and the connecting pipe tighter, preventing water leakage at the connection, and thus assisting the fixing mechanism to fix the connection;

[0016] 3. The pressure gauge can be used to detect the pressure in the connecting pipe, so that the staff can judge the airtightness of the connection according to the pressure change, which is convenient for the staff to inspect and repair the connection. The support frame can support the shell, so that the shell and pipe connection are placed flat, effectively preventing factors such as water vapor from affecting the pipe, thereby improving the practicality of the fixing mechanism.
