The existing grooved pipe joints use a combined connection method for multiple products, and one elbow, two sets of pipe fittings, and two sets of rubber rings are required for installation.

[0003] For example, a clamp elbow with the publication number CN212361170U includes a hoop head, a tie strap, and a fixing block. A tie strap is fixedly connected to the outer wall of the hoop head. A fixing block is fixedly connected to the inner wall of the lower tie strap. A nut is sleeved on the inner wall of the upper tie strap. A bolt is threadedly connected to the inner wall of the nut. A limit seat is fixedly connected to the lower side of the outer wall of the hoop head. A support rod is installed at the lower end of the limit seat. A runner is installed at the end of the support rod away from the limit seat. An adjusting mechanism is fixedly connected to the back of the support rod. A telescopic mechanism is sleeved on the outer wall of the runner. Through the combined use of structures such as the tie strap, the fixing block, the nut, and the bolt, a good fixing effect is achieved. Through the combined use of structures such as the connecting column, the chute, the slider, and the telescopic column, an adjustable height effect is achieved. However, when installing the existing clamp, it is generally fixed to the elbow pipe through bolts on both sides, and it needs to be twisted multiple times during installation and disassembly to tighten or unscrew the bolts.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] Please refer to Figure 1-10 , the present invention provides a technical solution: a clamp elbow that is convenient for installation, including a bent head 1, a connecting pipe 2, an upper clamp 6 and a lower clamp 7. A sealing block 3 is installed between the bent head 1 and the connecting pipe 2. A first clamping groove 4 is opened on the outer side of one end of the bent head 1, and a second clamping groove 5 is opened on the outer side of one side of the connecting pipe 2;

[0045] Connecting plates 8 are symmetrically arranged on both sides of the upper clamp 6. The connecting plates 8 are fixedly connected to the upper clamp 6, and a bolt pin 9 is slidably connected inside the connecting plates 8;

[0046] Horizontal plates 11 are fixedly connected to the upper parts of both ends of the lower clamp 7. A bottom plate 12 is installed below the horizontal plates 11. The bottom plates 12 are fixedly connected to the lower clamp 7, and two bottom plates 12 are symmetrically arranged;

[0047] An upper groove 13 is opened on one side inside the horizontal plate 11. A lower groove 14 is opened on one side inside the bottom plate 12. The bolt pin 9 is slidably connected to the upper groove 13, and the bolt pin 9 is slidably connected to the lower groove 14. A horizontal groove 15 is horizontally opened in the middle inside the bottom plate 12. A vertical groove 17 is opened on the other side inside the horizontal plate 11. An auxiliary groove 18 is opened on the other side inside the bottom plate 12. A locking rod 19 is slidably connected inside the auxiliary groove 18;

[0048] The top end of the bolt 9 is fixedly connected with a top block 10. The cross-section of the push block 16 is diamond-shaped. The gentler the inclination angles on both sides of the push block 16 are, the faster the push block 16 pushes the locking rod 19 to rise when the bolt 9 squeezes the push block 16. The locking rod 19 is slidably connected to the vertical groove 17.

[0049] One end of the horizontal groove 15 is communicated with the lower groove 14, and the other end of the horizontal groove 15 is communicated with the auxiliary groove 18. A push block 16 is slidably connected inside the horizontal groove 15. Both sides of the push block 16 are inclined upward. The bottom end of the locking rod 19 is inclined downward. One end of the push block 16 abuts against the inclined surface of the locking rod 19.

[0050] A guiding groove 20 is transversely formed inside the bottom plate 12. The guiding groove 20 is located above the horizontal groove 15. The bottom of the guiding groove 20 is communicated with the horizontal groove 15. One side of the top of the push block 16 is fixedly connected with a pressing block 21. A first spring 22 is fixedly installed inside the guiding groove 20. One end of the first spring 22 is fixedly connected with the pressing block 21. The pressing block 21 is slidably connected to the guiding groove 20.

[0051] A reset groove 23 is formed inside the bottom plate 12. The reset groove 23 is located on the side of the auxiliary groove 18 away from the horizontal groove 15. The reset groove 23 is communicated with the auxiliary groove 18. One side of the bottom of the locking rod 19 close to the reset groove 23 is fixedly connected with a reset block 24. The top end of the reset block 24 is fixedly connected with a second spring 25. The top end of the second spring 25 is fixedly connected with the inner top surface of the reset groove 23.

[0052] One side of the locking rod 19 close to the bolt 9 is fixedly connected with a toothed block 26. A side groove 34 is formed at the top of the connecting plate 8 on the side away from the upper clamp 6. A rotating shaft 35 is longitudinally installed inside the side groove 34. The rotating shaft 35 is rotatably connected to the connecting plate 8. A baffle 36 is fixedly connected to the outer side of the rotating shaft 35. A fourth spring 37 is fixedly connected to the top of the baffle 36. One end of the fourth spring 37 away from the baffle 36 is fixedly connected to the connecting plate 8.

[0053] The toothed blocks 26 are evenly arranged. A plurality of toothed blocks 26 are arranged at equal distances. There are no less than four toothed blocks 26.

[0054] A top groove 33 is formed inside the connecting plate 8. The top groove 33 is located between the upper clamp 6 and the side groove 34. The bolt 9 is slidably connected to the top groove 33.

[0055] The baffle 36 is located inside the side groove 34. The baffle 36 is rotatably connected to the side groove 34. The fourth springs 37 are symmetrically arranged. There are no less than two fourth springs 37. One end of the rotating shaft 35 passes through the connecting plate 8 and is fixedly connected with an adjusting block 38. The bottom of the lower clamp 7 is fixedly connected with a mounting plate 39. Fixing bolts 40 are installed around the mounting plate 39.

[0056] Example 1: As Figure 1-4 、 Figure 6-7 andFigure 9 As shown, a sealing block 3 is sleeved outside the first card slot 4, and then the connecting pipe 2 is inserted into the inside of the sealing block 3, so that the bent head 1 and the connecting pipe 2 are installed through the sealing block 3. The lower clamp 7 is attached to the bottom of the sealing block 3, and the upper clamp 6 is attached to the top of the sealing block 3.

[0057] Press the top block 10, and the top block 10 drives the pin 9 to insert into the top slot 33. The pin 9 continues to insert into the upper slot 13 and the lower slot 14 until the bottom end of the pin 9 abuts against the upper part of the left inclined surface of the push block 16. The pin 9 presses the push block 16, causing the push block 16 to slide towards the side of the locking rod 19. The push block 16 drives the pressure block 21 to move, and the pressure block 21 moves to compress the first spring 22. When the push block 16 moves, it will press the bottom inclined surface of the locking rod 19, causing the locking rod 19 to rise.

[0058] The locking rod 19 drives the reset block 24 to rise, and the reset block 24 compresses the second spring 25. The rising of the locking rod 19 also drives the tooth block 26 to rise. The tooth block 26 will push the baffle 36, causing the baffle 36 to drive the rotating shaft 35 to rotate, and the baffle 36 compresses the fourth spring 37. Until the bottom end of the pin 9 contacts the inner bottom surface of the lower slot 14, the push block 16 pushes the locking rod 19 to the highest position. At this time, the connecting plate 8 blocks the baffle 36, and the baffle 36 blocks the tooth block 26, thereby realizing the limit of the locking rod 19, facilitating the pressing and fixing of the lower clamp 7 and the upper clamp 6, enabling the rapid installation of the upper clamp 6 and the lower clamp 7, improving the installation efficiency of the upper clamp 6 and the lower clamp 7, and solving the problem that the existing clamps are generally fixed by bolts and need to be screwed multiple times during installation and disassembly. When dealing with a large number of clamp installations or disassembly, the installation and subsequent disassembly and maintenance efficiency is not high.

[0059] The top of the locking rod 19 is rotatably connected with a rotating member 27. One side of the rotating member 27 is provided with a pressure plate 32. One side of the rotating member 27 is provided with a pressure groove 28. The inside of the pressure groove 28 is fixedly connected with a sliding rod 29. The outside of the sliding rod 29 is slidably connected with a connecting strip 30. The upper part of the outside of the sliding rod 29 is sleeved with a third spring 31.

[0060] The top end of the third spring 31 is fixedly connected with the rotating member 27, and the bottom end of the third spring 31 is fixedly connected with the connecting strip 30. The connecting strip 30 is L-shaped. The end of the connecting strip 30 away from the sliding rod 29 is fixedly connected with the pressure plate 32.

[0061] Embodiment 2: As Figure 5 、 Figure 8 and Figure 10As shown, when the bolt 9 is pressed against the inner bottom surface of the lower slot 14, by rotating the rotating member 27 and pulling the pressure plate 32, the pressure plate 32 drives the connecting bar 30 to move. The connecting bar 30 compresses the third spring 31 until the pressure plate 32 is located above the top block 10. Then, release the pressure plate 32. The elastic force of the sliding rod 29 drives the connecting bar 30 and the pressure plate 32 to press down, so that the pressure plate 32 tightly presses the top block 10 and the bolt 9, thereby further fixing the upper clamp 6 and the lower clamp 7 and improving the fixing effect.

[0062] During disassembly, by rotating the rotating member 27, the pressure plate 32 is disengaged from the top of the top block 10. Then, rotate the adjusting block 38 counterclockwise. The adjusting block 38 drives the rotating shaft 35 and the baffle 36 to rotate, so that the baffle 36 releases the limit on the tooth block 26. The elastic force of the second spring 25 drives the reset block 24 and the locking rod 19 to press down and reset. The elastic force of the first spring 22 drives the push block 16 to move and reset, and then the bolt 9 and the upper clamp 6 can be pulled out, realizing convenient disassembly.

[0063] Working principle: When using this device, first, as Figure 1-10 shown, the sealing block 3 is sleeved outside the first slot 4, and then the connecting pipe 2 is inserted into the inside of the sealing block 3, so that the bent head part 1 and the connecting pipe 2 are installed through the sealing block 3. The lower clamp 7 is attached to the bottom of the sealing block 3, and the upper clamp 6 is attached to the top of the sealing block 3.

[0064] Press the top block 10. The top block 10 drives the bolt 9 to insert into the top slot 33. The bolt 9 continues to insert into the upper slot 13 and the lower slot 14 until the bottom end of the bolt 9 abuts against the upper part of the left inclined surface of the push block 16. The bolt 9 presses the push block 16, so that the push block 16 slides toward the side of the locking rod 19. The push block 16 drives the pressure block 21 to move. The pressure block 21 moves to compress the first spring 22. When the push block 16 moves, it will press the bottom inclined surface of the locking rod 19, causing the locking rod 19 to rise.

[0065] The locking rod 19 drives the reset block 24 to rise. The reset block 24 compresses the second spring 25. The rising of the locking rod 19 also drives the tooth block 26 to rise. The tooth block 26 will push the baffle 36, so that the baffle 36 drives the rotating shaft 35 to rotate, and the baffle 36 compresses the fourth spring 37. Until the bottom end of the bolt 9 contacts the inner bottom surface of the lower slot 14, the push block 16 pushes the locking rod 19 to the highest position. At this time, the connecting plate 8 blocks the baffle 36, and the baffle 36 blocks the tooth block 26, thereby realizing the limit on the locking rod 19.

[0066] When the bolt 9 is pressed against the inner bottom surface of the lower slot 14, by rotating the rotating member 27 and pulling the pressure plate 32, the pressure plate 32 drives the connecting bar 30 to move. The connecting bar 30 compresses the third spring 31 until the pressure plate 32 is located above the top block 10. Then release the pressure plate 32, and the elastic force of the sliding rod 29 drives the connecting bar 30 and the pressure plate 32 to press down, so that the pressure plate 32 presses tightly against the top block 10 and the bolt 9, thereby further fixing the upper clamp 6 and the lower clamp 7 and improving the fixing effect.

[0067] By rotating 27, the pressure plate 32 is disengaged from the top of the top block 10. Then rotate the adjusting block 38 counterclockwise. The adjusting block 38 drives the rotating shaft 35 and the baffle 36 to rotate, so that the baffle 36 releases the limit on the tooth block 26. The elastic force of the second spring 25 drives the reset block 24 and the locking rod 19 to press down and reset. The elastic force of the first spring 22 drives the push block 16 to move and reset, and then the bolt 9 and the upper clamp 6 can be pulled out, realizing convenient disassembly.
