DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Please refer to the attached Figure 1 -Attached Figure 4 A wear-resistant elbow that is easy to connect includes an elbow body 1, both ends of the elbow body 1 are fixed with flanges, one end of the elbow body 1 is provided with an alignment structure, the alignment structure includes a connecting rod 201 arranged at one end of the elbow body 1, a movable hole 202 is opened on the top surface of the connecting rod 201, a screw rod 203 is rotatably arranged inside the movable hole 202, one end of the screw rod 203 observes one side of the inner wall of the movable hole 202 and is fixed with a hand wheel, a mounting rod 204 is slidably arranged inside the movable hole 202, and the bottom end of the mounting rod 204 is hinged to the outer circular wall surface of the elbow body 1.

[0022] In the embodiment, a movable rod 3 is provided at the bottom end of the connecting rod 201, a mounting cylinder 301 is fixed to one side of the movable rod 3, a telescopic shaft 302 is slidably inserted inside the mounting cylinder 301, a spring 303 is provided inside the mounting cylinder 301, one end of the spring 303 abuts against one end of the telescopic shaft 302, and through the setting of the alignment structure, when the staff connects the elbow body 1 and the pipeline, they flip the mounting rod 204 hinged on the outer circular wall of the elbow body 1, so that the connecting rod 201 is located between the pipeline and the elbow body 1, and at the same time The movable rod 3 overlaps the pipeline, and the installation tube 301 is inserted into the corresponding opening at the pipeline flange to align the elbow body 1 and one end of the pipeline. The hand wheel is turned, and the screw 203 drives the installation rod 204 to move. The installation rod 204 drives the elbow body 1 and the flange at one end of the elbow body 1 to approach the pipeline flange, so that the flange at the elbow body 1 fits with the flange at the pipeline. The staff performs installation and connection, thereby simplifying the alignment work of the staff when installing the elbow body 1, making it convenient for the staff to connect the elbow body 1, and improving the connection efficiency of the wear-resistant elbow.

[0023] In the embodiment, a threaded hole is provided on the top surface of the connecting rod 201, and a bolt is connected to the internal thread of the threaded hole. The bottom end of the bolt is rotatably arranged with the top end of the movable rod 3. A limiting plate 4 is fixed to one side of the movable rod 3, and one side of the limiting plate 4 is fitted with one end of the connecting rod 201. When the elbow body 1 is not at the same height when aligned with the pipeline, the staff can turn the bolt to make the connecting rod 201 rise and fall under the action of the limiting plate 4, so that the connecting rod 201 drives the elbow body 1 to rise and fall through the mounting rod 204, ensuring that the elbow body 1 and the pipeline are at the same level.

[0024] In the embodiment, a mounting shell 5 is fixed to the bottom end of the movable rod 3, and both sides of the mounting shell 5 are open. Abutment plates 501 are slidably inserted into the two open sides of the mounting shell 5, and a clamping shaft 502 is slidably provided on the top surface of the abutment plate 501. A clamping hole 503 is provided on the top surface of the mounting shell 5, and the clamping shaft 502 is inserted into the clamping hole 503. When the movable rod 3 overlaps the pipeline, the bottom surface of the mounting shell 5 contacts the outer circular wall surface of the pipeline. The staff can pull out the abutment plate 501, and then lock the length through the clamping shaft 502 and the clamping hole 503 to expand the contact area between the mounting shell 5 and the outer wall of the pipeline, so that with the cooperation of the mounting cylinder 301, the influence of the deadweight of the elbow body 1 on the movable rod 3 is reduced, and the movable rod 3 is prevented from deflecting and shaking.

[0025] In the embodiment, the abutment plate 501 and the mounting shell 5 are both arc-shaped, and a rubber pad 2 is fixed to the bottom surface of the abutment plate 501. The rubber pad 2 is a prior art. The arc-shaped design of the abutment plate 501 and the mounting shell 5 can make them fit better with the outer wall of the pipe, and the rubber pad 2 increases the friction between the abutment arc plate 501 and the outer wall of the pipe.

[0026] In the embodiment, the other end of the telescopic shaft 302 is an inclined surface. When the elbow body 1 is moved to the pipeline and lifted, the lifted elbow body 1 contacts the inclined surface of the telescopic shaft 302 so that the telescopic shaft 302 is retracted into the mounting tube 301. When the telescopic shaft 302 pops out to the flange opening of the elbow body 1, the elbow body 1 is aligned with the pipeline.

[0027] Working principle: During use, when the staff connects the elbow body 1 and the pipeline, they flip the installation rod 204 hinged on the outer wall of the elbow body 1, so that the connecting rod 201 is located between the pipeline and the elbow body 1, and at the same time, the movable rod 3 overlaps the pipeline, and the installation cylinder 301 is inserted into the corresponding opening at the pipeline flange, so that the elbow body 1 and one end of the pipeline are aligned, and the hand wheel is turned, and the screw 203 drives the installation rod 204 to move, and the installation rod 204 drives the elbow body 1 and the flange at one end of the pipeline to approach the pipeline flange, so that the flange at the elbow body 1 fits with the flange at the pipeline, and the staff performs installation and connection. When the elbow body 1 is not at the same height when aligned with the pipeline, the staff can tighten the bolt to make the connecting rod 201 rise and fall under the action of the limit plate 4, so that the connecting rod 201 drives the elbow body 1 to rise and fall through the mounting rod 204 to ensure that the elbow body 1 is at the same level as the pipeline. When the movable rod 3 overlaps the pipeline, the bottom surface of the mounting shell 5 contacts the outer circular wall of the pipeline. The staff can pull out the abutment plate 501, and then lock the length through the clamping shaft 502 and the clamping hole 503 to expand the contact area between the mounting shell 5 and the outer wall of the pipeline. With the cooperation of the mounting cylinder 301, the influence of the deadweight of the elbow body 1 on the movable rod 3 is reduced to prevent the movable rod 3 from deflecting and shaking. The arc-shaped design of the abutment plate 501 and the mounting shell 5 can make it fit better with the outer wall of the pipeline. The rubber pad 2 increases the friction between the abutment arc plate 501 and the outer wall of the pipeline. When the telescopic shaft 302 pops out to the flange opening of the elbow body 1, the elbow body 1 is aligned with the pipeline.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
