Description

Technical Field

[0001] The utility model relates to a movable rotating elbow device. Background Art

[0002] In the existing dust removal duct system, a movable capture hood is often provided. In the prior art, the air hole of the capture hood is connected to the air hole of the duct system through a hose. However, the prior art has the following defects: when the air hole of the capture hood is vertically arranged with the air hole of the duct system, and the capture hood moves in a direction perpendicular to the central axis of the air hole of the capture hood; the angle between the end of the hose connected to the capture hood and the horizontal direction will change all the time, while the angle between the central axis of the air hole of the capture hood and the horizontal direction will not change, so the end of the hose connected to the capture hood will be easily bent, so that the hose at the capture hood will be easily sucked flat. Utility Model Content

[0003] The utility model solves the shortcomings of the prior art and provides a movable rotating elbow device which can prevent the hose from being sucked and collapsed.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] The utility model provides a movable rotating elbow device comprising an inner ring, an outer ring, an elbow and a bearing, wherein a bearing is installed on the inner side of the outer ring, one end of the inner ring is fixed on the inner ring of the bearing, and the other end is fixedly connected to the elbow; the outer ring is fixed on a capture cover so that the air hole of the capture cover is connected to the elbow, and the end of the elbow away from the inner ring is connected to the air hole of the pipeline system through a hose.

[0006] In this embodiment, the distance between the air holes of the capture hood and the air holes of the pipeline system is such that during the movement of the capture hood, the central axis of the end of the elbow connected to the air hole of the pipeline system is always in the same plane as the central axis of the air hole of the pipeline system.

[0007] In this embodiment, a connecting plate is fixed at one end of the outer ring, and an end cover is detachably installed at the other end. The outer ring is fixed to the capture cover through the connecting plate. The inner side wall of the outer ring, the connecting plate and the end cover together form an installation space matching the bearing. The bearing is installed in the installation space, and the end cover limits the axial displacement of the outer ring of the bearing.

[0008] In this embodiment, a screw hole is provided on the connecting plate, a second screw is installed in the screw hole, and the connecting plate is fixed to the capture cover by the second screw.

[0009] In this embodiment, the end cover is provided with an oil nozzle for adding lubricating oil to the bearing.

[0010] In this embodiment, the end cover is fixed to the outer ring by a third screw.

[0011] In this embodiment, the elbow is sleeved on the inner ring, and the elbow and the inner ring are fixed by a first screw.

[0012] In this embodiment, the elbow is connected to the hose via a clamping ring.

[0013] When the air hole of the capture cover is vertically arranged with the air hole of the pipeline system, and the capture cover moves in a direction perpendicular to the central axis of the air hole of the capture cover; and the elbow can rotate relative to the outer ring; therefore, when the capture cover moves, when the angle between the end of the hose connected to the elbow and the horizontal direction changes, the elbow can be driven to rotate in the direction of the hose rotation, thereby preventing the hose from bending at the capture cover, thereby preventing the hose from being sucked out. In summary, the movable rotating elbow device provided by the device scheme has the effect of preventing the hose from being sucked out. BRIEF DESCRIPTION OF THE DRAWINGS
