[0033] The present utility model provides a pipe winding wheel structure, as Figures 1 to 8 shown, for winding a high-pressure pipe 8, including a first pipe winding wheel 1 and a second pipe winding wheel 2 connected to each other. The high-pressure pipe 8 includes a connection end 81 and a working end 82. A first arc-shaped groove 11 is provided on the first pipe winding wheel 1. The first arc-shaped groove 11 is used to fix the connection end 81 of the high-pressure pipe 8. The bending inner diameter of the first arc-shaped groove 11 is D 1 , the outer diameter of the high-pressure pipe 8 is D 2 , D 1 > D 2. In this embodiment, the high-pressure pipe 8 is wound around the pipe winding wheel structure, and the rotation of the pipe winding wheel structure drives the winding or release of the high-pressure pipe 8. The structure is simple and the operation is convenient. Moreover, the first pipe winding wheel 1 is provided with a first arc-shaped groove 11, and the connection end 81 of the high-pressure pipe 8 is installed and fixed in the first arc-shaped groove 11. The bending inner diameter D of the first arc-shaped groove 11 1 is greater than the outer diameter D of the high-pressure pipe 8 2 . When high-pressure water flows through the inside of the high-pressure pipe 8, the radial force generated by the high-pressure water can be dispersed through the relatively long first arc-shaped groove 11 to the radial force on the high-pressure pipe 8, avoiding the problem that the outer wall of the high-pressure pipe 8 is locally overstressed in the first arc-shaped groove 11 and accelerating wear and rapid rupture with high-frequency vibration, thus improving the wear resistance and product performance of the high-pressure pipe 8.
[0034] Specifically, as shown in Figure 1 , Figure 2 and Figure 8 , the pipe winding wheel structure is installed on a cleaning machine (not shown). By rotating the first pipe winding wheel 1 or the second pipe winding wheel 2, the rotation of the pipe winding wheel structure can be driven, so as to realize the release or winding of the high-pressure pipe 8. Among them, the first pipe winding wheel 1 includes a first hub 14, the second pipe winding wheel 2 includes a second hub 22, the first hub 14 and the second hub 22 are connected to each other to form a hub for winding the high-pressure pipe 8, and the first hub 14 and the second hub 22 are connected and fixed by a first screw 71. Of course, the first hub 14 and the second hub 22 can be an integral structure. The connection end 81 of the high-pressure pipe 8 is installed in the first arc-shaped groove 11 to realize the fixed connection between the high-pressure pipe 8 and the pipe winding wheel structure. The connection end 81 of the high-pressure pipe 8 is communicated with a water pump (not shown), and the working end 82 of the high-pressure pipe 8 is communicated with a spray gun (not shown). After the high-pressure water pumped out by the water pump passes through the connection end 81 and the working end 82 of the high-pressure pipe 8 in sequence, it is sprayed out by the spray gun. Further, D 1 >2D 2 , so that the first arc-shaped groove 11 has a relatively long bending and gradual transition to ensure that when high-pressure water flows through the inside of the high-pressure pipe 8, there is no extrusion between the outer wall of the high-pressure pipe 8 and the first arc-shaped groove 11, so as to reduce vibration wear and improve the service life of the high-pressure pipe 8. Moreover, the inner surface of the first arc-shaped groove 11 is smooth, reducing the friction coefficient.
[0035] As an implementation manner, as shown in Figure 1 and Figure 5As shown, the first arc-shaped groove 11 is provided on the side of the first pipe winding wheel 1 away from the second pipe winding wheel 2, that is, the first arc-shaped groove 11 is provided on the outer side surface of the first pipe winding wheel 1, and a through hole 12 is provided at one end of the first pipe winding wheel 1 in the first arc-shaped groove 11 for the connection end 81 of the high-pressure pipe 8 to pass through. In this embodiment, the first arc-shaped groove 11 is provided on the outer side surface of the first pipe winding wheel 1, that is, the first arc-shaped groove 11 faces outward, which is convenient for manual installation of the connection end 81 of the high-pressure pipe 8, and also reduces the winding space occupied by the connection end 81 of the high-pressure pipe 8 between the first pipe winding wheel 1 and the second pipe winding wheel 2, leaving more winding space and avoiding congestion in the winding of the high-pressure pipe 8.

The first arc-shaped groove 11 and the second arc-shaped groove 31 surround and form a space for accommodating the high-pressure pipe 8, avoiding friction between the outer wall of the high-pressure pipe 8 and the first pipe winding wheel 1 or the cover plate 3 and reducing wear.
[0038] As an implementation manner, as Figure 2 and Figure 5 shown, the pipe winding wheel structure further includes a flexible sheath 4, and the flexible sheath 4 is used to sleeved on the connection end 81 of the high-pressure pipe 8 and contacts with the first arc-shaped groove 11 and the second arc-shaped groove 31.

[0039] As an implementation manner, as Figures 5 to 8 shown, the pipe winding wheel structure further includes a connector 5. The connector 5 sequentially penetrates through the first pipe winding wheel 1 and the second pipe winding wheel 2.

The rotating shaft 52 passes through the second shaft hole 21 and is connected to the second reel 2. By rotating the first reel 1 or the second reel 2, the winding or releasing of the high-pressure pipe 8 is realized.
[0041] As an implementation manner, as Figures 5 to 8 shown, the two-way valve assembly 51 includes a two-way joint 511 and a high-pressure pipe joint 512. The first end of the two-way joint 511 passes through the first shaft hole 13 and is connected to the connection end 81 of the high-pressure pipe 8. The second end of the two-way joint 511 is connected to the first end of the high-pressure pipe joint 512. The second end of the high-pressure pipe joint 512 is connected to the rotating shaft 52.
[0042] As an implementation manner, as Figures 5 to 8 shown, the two-way valve assembly 51 further includes a first U-shaped pin 513 and a second U-shaped pin 514. The two-way joint 511 and the high-pressure pipe 8 are fixedly connected through the first U-shaped pin 513, and the high-pressure pipe joint 512 and the rotating shaft 52 are fixedly connected through the second U-shaped pin 514. Further, the two-way valve assembly 51 further includes a sleeve 515 and a snap ring 516. An annular groove 5121 is provided on the outer periphery of the first end of the high-pressure pipe joint 512, and the snap ring 516 is stuck in the annular groove 5121 to improve the connection stability between the two-way joint 511 and the high-pressure pipe joint 512 and prevent shaking between the two-way joint 511 and the high-pressure pipe joint 512. The sleeve 515 is sleeved on the connection part of the two-way joint 511 and the high-pressure pipe joint 512 to further play a fixing role and can bear a certain impact load, reducing the vibration of the connection part of the two-way joint 511 and the high-pressure pipe joint 512 during the operation of the cleaning machine, thereby reducing the damage of the parts. Specifically, the second end of the high-pressure pipe joint 512 is inserted into the central hole 521 of the rotating shaft 52, and then the second U-shaped pin 514 is passed through the rotating shaft 52 and inserted into the second card slot 5122 of the high-pressure pipe joint 512 to realize the fixed connection between the high-pressure pipe joint 512 and the rotating shaft 52.

Both the high-pressure pipe joint 512 and the two-way joint 511 are provided with through cavities (not shown) for water to pass through. After the output end of the water pump passes through the central hole 521 of the rotating shaft 52, it is connected to the high-pressure pipe joint 512. High-pressure water enters the high-pressure pipe 8 after passing through the high-pressure pipe joint 512 and the two-way joint 511 in sequence. The arrow in the flow channel cavity 53 indicates the water flow direction.
[0044] As an implementation, as Figure 1 and Figure 3 shown, the reel structure further includes a crank 6. A circular hole 15 is provided on the side of the first reel 1 away from the second reel 2. The crank 6 is installed in the circular hole 15. By rotating the crank 6, the first reel 1 and the second reel 2 are driven to rotate around the connecting member 5, so that the high-voltage wires 8 on the first hub 14 and the second hub 22 can be wound or released, making the rotation more convenient.
[0045] The installation sequence of the reel structure includes:
[0046] (1) The second end of the high-pressure pipe joint 512 is inserted into the central hole 521 of the rotating shaft 52, and then the second U-shaped pin 514 is inserted through the rotating shaft 52 and into the second card slot 5122 of the high-pressure pipe joint 512;
[0047] (2) The rotating shaft 52 and the high-pressure pipe joint 512 installed in step (1) are passed through the second shaft hole 21 in the middle of the second reel 2. Then, the sleeve 515 is sleeved on the second end of the high-pressure pipe joint 512. Next, the second end of the two-way joint 511 is sleeved on the first end of the high-pressure pipe joint 512, and the snap ring 516 is clamped in the annular groove 5121 at the first end of the high-pressure pipe joint 512;
[0048] (3) The workpiece installed in step (2) is installed on the first reel 1, and the first reel 1 and the second reel 2 are fixed by three first screws 71;
[0049] (4) The flexible sheath 4 is sleeved from the connection end 81 of the high-pressure pipe 8, and the end of the flexible sheath 4 is kept flush with the end of the connection end 81 of the high-pressure pipe 8, so that the flexible sheath 4 can completely wrap the connection end 81 of the high-pressure pipe 8, preventing part of the connection end 81 of the high-pressure pipe 8 from contacting the first arc-shaped groove 11 and the second arc-shaped groove 31;
[0050] (5) The high-pressure pipe 8 with the flexible sheath 4 installed is passed through the through hole 12 of the first reel 1, and the connection end 81 of the high-pressure pipe 8 is inserted into the through cavity (not shown) of the two-way joint 511. The first U-shaped pin 513 is clamped into the first card slot 5111 of the two-way joint 511 to clamp the high-pressure pipe 8 through the first U-shaped pin 513;
[0051] (6) Install the fixed high-pressure pipe 8 with the flexible sheath 4 into the first arc-shaped groove 11 of the first pipe reel 1, and install the cover plate 3 on the first pipe reel 1, and fix it with 2 second screws 72;
[0052] (7) Install the crank 6 into the circular hole 15 of the first pipe reel 1 and fix it with the third screw 73.
[0053] The beneficial effects of the utility model include:
[0054] (1) A larger first arc-shaped groove 11 is added to the first pipe reel 1. The inner surface of the first arc-shaped groove 11 is smooth, which reduces the friction coefficient. In addition, the bending radius of the arc is more than twice the outer diameter of the high-pressure pipe 8. Since the first arc-shaped groove 11 of the first pipe reel 1 for fixing the high-pressure pipe 8 has a long bending and gradual transition, when high-pressure water flows through the high-pressure pipe 8, the radial force generated can disperse the radial force of the high-pressure pipe 8 through the long arc-shaped groove of the first pipe reel 1, and it will not cause the surface of the high-pressure pipe 8 to be stressed at a very small position in the arc-shaped groove that restricts the first pipe reel 1, resulting in excessive local stress and accelerating the wear of the local part of the high-pressure pipe 8 and quickly cracking with high-frequency vibration;
[0055] (2) The cover plate 3 is provided with a larger second arc-shaped groove 31. The inner surface of the second arc-shaped groove 31 is smooth, which reduces the friction coefficient and restricts the high-pressure pipe 8 in the second arc-shaped groove 31;
[0056] (3) The flexible sheath 4 is made of soft material. Since the high-pressure pipe 8 is installed in the second arc-shaped groove 31 of the cover plate 3 and the first arc-shaped groove 11 of the first pipe reel 1, the flexible sheath 4 isolates the direct contact between the high-pressure pipe 8 and the hard materials of the cover plate 3 and the first pipe reel 1, slowing down the wear of the high-pressure pipe 8; and the flexible sheath 4 is made of soft material, absorbing part of the vibration frequency;
[0057] (4) Through the above measures, the wear resistance of the high-pressure pipe 8, the first pipe reel 1 and the cover plate 3 is improved; and through the durability test, the wear resistance time > 100H, improving the problem that the original high-pressure pipe 8 was worn extremely fast, and the high-pressure pipe 8 was worn and cracked and leaked water after continuous use for 10H.
