Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a pipeline connection device which is easy to replace. Background Art

[0002] The water supply pipe of a water conservancy project refers to the pipeline or canal from the water source intake to the water plant and from the water plant to the water supply network. It only serves the purpose of water transportation and does not distribute water along the line. The water supply pipeline should be shortened as much as possible to reduce the occupation of farmland, facilitate the construction, operation and maintenance of the canal, and ensure the safety of water supply.

[0003] The utility model with the existing authorization announcement number CN218178214U discloses a pipeline connection device, including a first connecting pipe, a first clamping pipe connected to the outer side of the first connecting pipe, a first hose connected to one end of the first clamping pipe, and a first fixed pipe connected to the side of the first hose away from the first clamping pipe.

[0004] The above technical solution solves the problem that the current pipeline connection is usually directly welded, which makes it difficult to repair and replace the pipeline when it is damaged; it is also inconvenient to adjust the angle of the pipeline, resulting in poor pipeline connection effect. However, the above technical solution uses two hoses in parallel, which increases the length of the hose, thereby increasing the risk of hose bursting. In addition, the increase in hose length will also reduce the overall water delivery capacity and life of the pipeline, so it is not recommended to use more hose connections. In addition, the above technical solution does not have the function of fixing the pipeline when replacing the pipeline, and cannot stabilize the pipeline. In this case, the installation is prone to errors, resulting in slight air leakage and pressure relief at the pipeline connection.

[0005] Therefore, those skilled in the art provide a pipe connection device that is easy to replace to solve the problems raised in the above background technology. Utility Model Content

[0006] The purpose of the utility model is to provide a pipe connection device which is easy to replace, so as to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A pipe connection device that is easy to replace, comprising a base, with a fixing mechanism arranged above the base;

[0009] The fixing mechanism includes two water pipes, and the ends of the two water pipes close to each other are fixedly connected to a bellows. Six threaded rods are arranged on the outside of one of the water pipes, and the end of each threaded rod close to the bellows passes through the water pipe and the bellows in sequence and extends to the outside of the water pipe. Two sliding blocks are slidably connected to the inside of the base, and the upper surface of each sliding block is fixedly connected to two spring buffers. The upper surface of each group of spring buffers is fixedly connected to a fixing block, and the upper surface of each fixing block is fixedly connected to a lower fixing ring. The outer surface of each lower fixing ring is movably hinged to an upper fixing ring, and the inner wall of each lower fixing ring and the inner wall of each upper fixing ring are in contact with the outer surface of the water pipe.

[0010] As a further solution of the utility model: a mounting plate is fixedly connected to the bottom surface of the base, and nine mounting holes are opened on the bottom surface of the mounting plate.

[0011] As a further solution of the utility model: four supporting legs are fixedly connected to the bottom surface of the base, and a non-slip pad is fixedly connected to the bottom surface of each supporting leg.

[0012] As a further solution of the utility model: handles are fixedly connected to the left and right side surfaces of the base, and the outer surface of each handle is covered with an anti-slip cover.

[0013] As a further solution of the utility model: a threaded nail is arranged above each of the upper fixing rings, and the bottom end of each of the threaded nails passes through the upper fixing ring and the lower fixing ring in sequence and extends to the bottom of the lower fixing ring.

[0014] As a further solution of the utility model: the outer surface of each threaded rod is threadedly connected with four threaded caps, and the side surfaces of each group of threaded caps that are close to each other are in contact.

[0015] As a further solution of the utility model: two limit rods are fixedly connected to the inner wall of the base, and the inner wall of each sliding block is slidably connected to the outer surface of the limit rod.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

In addition, a small amount of high-strength explosion-proof corrugated pipes can be used to effectively reduce the risk of hose bursting.

[0018] By providing a sliding block, a spring buffer, a fixed block, a lower fixed ring and an upper fixed ring which cooperate with each other, the water pipes at both ends can be fixed, thereby solving the error caused by instability during the installation of the water pipes and avoiding the problem of slight air leakage and pressure relief at the pipe connection.

DETAILED DESCRIPTION

[0024] See also Figure 1-4 A pipe connection device that is easy to replace includes a base 1, a fixing mechanism 2 is arranged above the base 1, the fixing mechanism 2 includes two water pipes 201, a mounting plate 3 is fixedly connected to the bottom surface of the base 1, and nine mounting holes 4 are opened on the bottom surface of the mounting plate 3. By cooperating with the mounting plate 3 and the mounting holes 4, the height position of the device can be expanded.

[0025] The two water pipes 201 are fixedly connected to each other at one end thereof which is close to each other, and six threaded rods 203 are arranged on the outside of one of the water pipes 201. Four supporting legs 5 are fixedly connected to the bottom surface of the base 1, and an anti-skid pad 6 is fixedly connected to the bottom surface of each supporting leg 5. The supporting legs 5 and the anti-skid pad 6 cooperate with each other to increase the stability of the device, and prevent it from sliding sideways when placed on a support.

[0026] One end of each threaded rod 203 close to the bellows 202 passes through the water pipe 201 and the bellows 202 in sequence and extends to the outside of the water pipe 201. The left and right sides of the base 1 are fixedly connected with handles 7. The outer surface of each handle 7 is covered with an anti-slip sleeve 8. The handles 7 and the anti-slip sleeve 8 cooperate with each other to facilitate the staff to transfer the device. The anti-slip sleeve 8 prevents the handles 7 from slipping and relieves the hands.

[0027] The base 1 is internally slidably connected to two sliding blocks 204, and the upper surface of each sliding block 204 is fixedly connected to two spring buffers 205. The outer surface of each threaded rod 203 is threadedly connected to four threaded caps 10, and the side surfaces of each group of threaded caps 10 that are close to each other are in contact. The threaded caps 10 are provided to reinforce the bellows 202, and the design of the double-layer threaded caps 10 is used to prevent the threads from slipping and falling off.

[0028] The upper surface of each group of spring buffers 205 is fixedly connected to a fixed block 206, and the upper surface of each fixed block 206 is fixedly connected to a lower fixed ring 207. The inner wall of the base 1 is fixedly connected to two limit rods 11, and the inner wall of each sliding block 204 is slidably connected to the outer surface of the limit rod 11. By setting the limit rod 11, the sliding block 204 is limited, ensuring that the two sliding blocks 204 are in a horizontal line, so that the two ends of the water pipes 201 after fixation are also relatively horizontal, thereby increasing the accuracy of installing the water pipes 201.

[0029] The outer surface of each lower fixing ring 207 is movably hinged with an upper fixing ring 208, the inner wall of each lower fixing ring 207 and the inner wall of each upper fixing ring 208 are in contact with the outer surface of the water pipe 201, and a threaded nail 9 is arranged above each upper fixing ring 208, and the bottom end of each threaded nail 9 passes through the upper fixing ring 208 and the lower fixing ring 207 in sequence and extends to the bottom of the lower fixing ring 207. The threaded nail 9 is arranged to threadably fix the upper fixing ring 208 and the lower fixing ring 207, so as to fix the water pipe 201.

[0030] The working principle of the utility model is as follows: when in use, the old and damaged pipes to be replaced are first cut off, and then the worker holds the handle 7 and places the device under the water pipe 201 to be replaced, and manually adjusts the two sliding blocks 204 to a suitable position, and then uses the lower fixing ring 207 and the upper fixing ring 208 to wrap up the water pipe 201, and uses the threaded nail 9 to fix the lower fixing ring 207 and the upper fixing ring 208 together. At this time, the cooperation of the fixing block 206 and the spring buffer 205 can buffer some downward force, play the role of fixing and clamping the water pipes 201 at both ends after cutting, and in a relatively horizontal position, to prepare for the subsequent installation of the corrugated pipe 202;

[0031] Use a bellows 202 of suitable length and cooperate with six threaded rods 203 to connect the water pipes 201 at both ends with the bellows 202. Finally, two threaded caps 10 are threadedly connected at both ends of each threaded rod 203 to fix it and increase stability. The rubber sleeve inside the bellows 202 can seal the pipe connection. This easy-to-replace pipe connection device can effectively reduce the risk of hose bursting, solve the errors caused by instability during pipe installation, and avoid problems such as slight air leakage and pressure relief at pipe connections.

[0032] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
