Description

Technical Field

[0001] The utility model relates to the technical field of elbows, in particular to a quick-install flange type elbow. Background Art

[0002] Elbow is a commonly used pipe fitting used for connecting pipes at bends to change the direction of the pipe. The existing ways to connect elbows to pipes include direct welding, flange connection, hot melt connection, threaded connection and socket connection.

[0003] When installing an elbow between two sections of pipe, the ends of the pipe and the elbow are generally matched with each other. For example, flanges are installed at the ends of the elbow and the pipe, or the ends of the flanges are threaded, or the ends of the flanges are installed with matching socket-type components. However, when replacing some old elbows, flanges are installed at the ends of the pipes. Then, a flange must be installed on the elbow before it can be replaced and connected to the pipe, which has certain limitations. At the same time, the installation between the flanges is more cumbersome. Utility Model Content

The flange 3 is entirely accommodated between the arc-shaped clamping block 7 and the slider 6, and the flange 3 is entirely accommodated in the middle of the disc 5.

[0021] like Figures 1 to 4 As shown, the end of the disc 5 away from the elbow 2 is chamfered.

[0022] It is convenient to store the flange 3 as a whole in the middle of the disc 5.

[0023] like Figures 1 to 4 As shown, a limit rod 8 is symmetrically fixedly installed in a ring array on one side of the disk 5 with the central axis of the disk 5 as the axis, and a limit hole 9 is provided on the slider 6 corresponding to the position of the limit rod 8. The limit hole 9 is slidably connected to the limit rod 8. An extrusion spring 10 is sleeved on the outer side of the bottom end of the limit rod 8. One end of the extrusion spring 10 is fixedly connected to the disk 5, and the other end of the extrusion spring 10 is fixedly connected to the slider 6.

[0024] Align the disc 5 at the end of the elbow 2 with the flange 3 on the connecting pipe 1. The flange 3 will squeeze the inclined end of the arc-shaped block 7, and will drive the slider 6 installed with the arc-shaped block 7 to slide along the outside of the limit rod 8. At this time, the extrusion spring 10 is in a compressed state, and the arc-shaped block 7 will completely pass through the through-hole 4 on the flange 3. The flange 3 will be completely accommodated in the position between the several arc-shaped blocks 7 and the slider 6. As the extrusion spring 10 pushes the slider 6, the arc surface of the arc-shaped block 7 will be driven to fit the inner wall of the through-hole 4, which is used for fast and stable installation between the elbow 2 and the connecting pipe 1.

[0025] like Figures 1 to 4As shown, the outer ring of the disc 5 is provided with sliding holes 11 in an annular array with the central axis of the disc 5 as the axis, and an extrusion rod 12 is slidably installed inside the sliding hole 11, and the extrusion rod 12 is set in the middle of the slider 6.

[0026] By pressing down the extrusion rod 12, the extrusion rod 12 will squeeze the slider 6 until the arc-shaped block 7 is moved to a position where it can completely pass through the through-hole 4 on the flange 3, and then the elbow 2 and the connecting pipe 1 are separated. The arc-shaped block 7 can completely pass through the through-hole 4 on the flange 3, which is used for quick disassembly between the elbow 2 and the connecting pipe 1.

[0027] like Figures 1 to 4 As shown, the outer ring of the disc 5 is rotatably mounted with a swivel 13, the inner ring of the swivel 13 is integrally fixedly mounted with a circular swivel block 14, the outer ring of the disc 5 is provided with a circular swivel groove 15, the circular swivel groove 15 is rotatably connected to the circular swivel block 14, the inner wall of the outer ring of the swivel 13 is integrally fixedly mounted with a triangular block 16, and the triangular block 16 is in extrusion contact with the extrusion rod 12.

[0028] By rotating the rotating ring 13 , the triangular blocks 16 on the rotating ring 13 will squeeze the multiple extrusion rods 12 simultaneously, thereby facilitating the overall movement of the multiple arc-shaped clamping blocks 7 .

[0029] like Figures 1 to 4 As shown, a mounting groove 17 is formed on the inner wall of the outer ring of the disk 5 , and a sealing ring 18 is installed inside the mounting groove 17 .

[0031] The utility model provides a quick-install flange elbow, the specific working principle is as follows:

[0032] When the device is in use, the disc 5 at the end of the elbow 2 is aligned with the flange 3 on the connecting pipe 1, and the flange 3 will be completely received in the middle of the disc 5. During this process, the flange 3 will squeeze the inclined end of the arc-shaped clamping block 7, and will drive the slider 6 installed with the arc-shaped clamping block 7 to slide along the outside of the limit rod 8. At this time, the extrusion spring 10 is in a compressed state, and the arc-shaped clamping block 7 will move to a position where it can completely pass through the through-hole 4 on the flange 3. Subsequently, the arc-shaped clamping block 7 completely passes through the through-hole 4 on the flange 3, and the flange 3 will be completely received in a position between several arc-shaped clamping blocks 7 and the slider 6. As the extrusion spring 10 pushes the slider 6, the arc surface of the arc-shaped clamping block 7 will be driven to fit the inner wall of the through-hole 4, which is used for quick installation between the elbow 2 and the connecting pipe 1.

[0033] By rotating the swivel 13, the triangular block 16 on the swivel 13 will squeeze the extrusion rod 12, driving the extrusion rod 12 to slide inside the sliding hole 11, and the extrusion rod 12 will squeeze the slider 6, driving the slider 6 to slide along the outside of the limit rod 8 until the arc-shaped clamping block 7 is moved to a position where it can completely pass through the through-hole 4 on the flange 3, and then the elbow 2 and the connecting pipe 1 are separated. The arc-shaped clamping block 7 can completely pass through the through-hole 4 on the flange 3, which is used for quick disassembly between the elbow 2 and the connecting pipe 1.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
