Description

Technical Field

[0001] The present invention relates to the field of pipe reel equipment, and in particular to a pipe reel. Background Art

[0002] Hose reels are auxiliary equipment for centralized use of irrigation and pneumatic tools. They allow the free retraction and extension of the water and air pipes used by these tools. These pipes often need to be moved simultaneously during use. Without hose reels, when the distance between these pipes changes, a significant portion of the pipes will be dragged onto the ground or in other directions. This can cause the pipes to bend or become trapped by other components, impacting the flow of liquid or gas and creating a mess in the workplace or work surface. Therefore, dedicated hose reels are currently commonly used for reeling pipes.

[0003] A pipe connection structure for connecting pipelines is usually installed inside the hose reel. The pipe connection structure is a hollow structure and one end is connected to the external water supply or gas supply equipment through a short pipe, and the other end is connected to the long pipe wound on the winding wheel. Liquid or gas can enter the long pipe from the external water supply equipment or gas supply equipment through the short pipe and the pipe connection structure for circulation and output.

[0004] The pipe connection structure inside the existing hose reel includes a long pipe connector positioned and connected to the winding wheel, and a short pipe connector positioned and connected to the hose reel casing. The long pipe connector and the end pipe connector are detachably sleeved together and fastened by a retaining spring. After being filled with water, this pipe connection structure is prone to axial displacement of the short pipe connector relative to the long pipe connector under water pressure, causing the retaining spring to fall off, resulting in loss of product function. In addition, the short pipe connector and the casing are fixed with screws. The displacement of the short pipe connector will cause deformation of the casing, indirectly affecting the stability of other components connected to the casing. Summary of the Invention

[0005] In response to the deficiencies in the prior art, the present invention provides a hose reel in which the long tube connector and the short tube connector inside the hose reel are axially locked by a support limiter, so that when the long tube is pulled out or retracted around the winding wheel, the winding wheel drives the support limiter and the long tube connector to rotate, which is more stable and increases the service life.

The long tube connector and the short tube connector of the pipe connecting structure are axially locked by a support limiter. When the water pipe is used to store water, the inflow of water will directly form water pressure on the long tube connector and the short tube connector, causing the two to expand outward. The long tube connector and the short tube connector are axially locked by the support limiter. When the pipe connecting structure drives the second sleeve to move axially relative to the first sleeve in the direction of separating from the first sleeve under the action of water pressure, the first limit seat can be limited by the support limiter connected to the long tube connector to prevent the second sleeve from moving axially relative to the first sleeve in the direction of separating from the first sleeve. This can effectively reduce the deformation pressure on the pipe connecting structure and the shell caused by the water pressure, thereby improving the overall stability of the product and better extending its service life.

[0037] like Figures 1-11As shown, as an embodiment of the present invention, a hose reel is provided, which includes a housing 1, a winding wheel 2, a long pipe (not shown in the figure), a short pipe (not shown in the figure), and a pipe connecting structure 5. The shell 1 has a first shell plate 11 and a second shell plate 12 arranged relatively to each other. The winding wheel 2 is arranged between the first shell plate 11 and the second shell plate 12, and is rotatably connected to the first shell plate 11 through a rotating shaft. A first connecting seat 21 is provided on the side of the winding wheel 2 away from the first shell plate 11, and a second connecting seat 13 is provided on the side of the second shell 1 away from the first shell 1. A base channel 14 for arranging a pipe connection structure 5 is opened on the second connecting seat 13, wherein the pipe connection structure 5 includes a long tube connector 51, a short tube connector 52, and a support limiter 53. The long tube connector 51 includes a first sleeve 511 arranged coaxially with the rotating shaft, a first support seat 512 connected to the inner end of the first sleeve 511 and fixedly connected to the first connecting seat 21, a second support seat 513 connected to the outer end of the first sleeve 511, and a first connecting head 514 connected to the first sleeve 511, and the inlet end 31 of the long tube 3 is connected to the first connecting head 514. The short pipe connecting piece 52 includes a second sleeve 521 arranged coaxially with the rotating shaft, and a second connecting head 522 communicating with the second sleeve 521. The second sleeve 521 is detachably connected to the first sleeve 511, and the outlet end 41 of the short pipe fitting 4 is communicated with the second connecting head 522; the second sleeve 521 is provided with a first limiting seat 523 along its outer circumference, and the supporting limiting member 53 is arranged on the outer side of the second connecting seat 13 and is rotatably sleeved on the second sleeve 521, and is limited to the outer side of the first limiting seat 523 and is fixedly connected to the second supporting seat 513. When the long pipe fitting 3 is pulled out or retracted around the winding wheel 2, it can drive the supporting limiting member 53 to rotate with the long pipe connecting piece 51 relative to the short pipe connecting piece 52. When the water pipe is used to store water, the inflow of water will directly form water pressure on the long pipe connecting piece 51 and the short pipe connecting piece 52, causing the two to expand outward, and the pipe connection structure The long tube connector 51 and the short tube connector 52 of the structure 5 are axially locked by the support limiter 53. When the water pipe is used to store water, the inflow of water will directly form water pressure on the long tube connector 3 and the short tube connector 4, causing the two to expand outward. The long tube connector 51 and the short tube connector 52 are axially locked by the support limiter 53. When the pipe connecting structure 5 drives the second sleeve 521 to move axially relative to the first sleeve 511 toward the direction of separation from the first sleeve 511 under the action of water pressure, the first limit seat 523 can be limited by the support limiter 53 connected to the long tube connector 51, thereby preventing the second sleeve 521 from moving axially relative to the first sleeve 511 toward the direction of separation from the first sleeve 511. This can effectively reduce the deformation pressure caused by the water pressure on the pipe connecting structure 5 and the shell 1, thereby improving the overall stability of the product and better extending its service life.

[0038] The first connecting head 514 is provided with a first connecting channel 518 communicating with the first sleeve 511, and the second connecting head 522 is provided with a second connecting channel 526 communicating with the second sleeve 521. The first connecting head 514 is provided with a first connecting port 519 communicating with the first connecting channel 518 on an end away from the first sleeve 511, and a first socket 56 communicating with the first connecting channel 518 is provided on an end of the first sleeve 511 close to the second support seat 513; the second connecting head 522 is provided with a second connecting port 527 communicating with the second connecting channel 526 on an end away from the second sleeve 521, and the second socket 57 communicating with the second connecting channel 526 on an end of the second sleeve 521 close to the first sleeve 511. The second shell plate 12 is provided with a water inlet channel 121 for the short pipe 4 to pass through. The water inlet channel 121 is arranged along the upper layer of the second shell plate 12, so that the short pipe 4 is connected to the second connecting head 522 after passing through the water inlet channel 121, thereby positioning the position of the short pipe connector 52.

[0039] like Figure 10 As shown, the support limit member 53 has a first limit portion 531 limited to the outside of the first limit seat 523, and a second limit portion 532 limited to the outside of the first connecting seat 21. The outer diameter of the second limit portion 532 is larger than the inner diameter of the base channel 14, which can ensure that the support limit member 53 will not pass through the base channel 14 due to external factors such as shaking during use, prevent the short tube connector 52 from abutting against the second shell plate 12 to cause deformation of the casing, and increase structural stability.

[0040] like Figure 7-11 As shown, the second support seat 513 is rotatably mounted in the base channel 14, and the support limit member 53 also includes a fixing portion 533 arranged between the first limiting portion 531 and the second limiting portion 532. The fixing portion 533 and the second support seat 513 are detachably connected through a second assembly part (not shown in the figure), thereby strengthening the connection between the short pipe part 4 and the long pipe part 3 and making the overall structure more stable. The second assembly part can be set as a fixing part such as a nut, a screw, or a pin.

[0041] like Figure 8 and Figure 10 As shown, a plurality of second assembly channels 535 are provided through the fixing portion 533, and the second support seat 513 is extended outward from the outer wall of the first sleeve 511 along the outer peripheral side of the first sleeve 511. The outer side surface of the second support seat 513 is recessed with a plurality of second matching channels 515 arranged corresponding to the second assembly channels 535. The fixing portion 533 and the second support seat 513 are detachably connected in the corresponding second assembly channels 535 and the second matching channels 515 through a second assembly part (not shown in the figure). Through the matching, the fixing portion 533 and the second support seat 513 can be fixed and moved without deviation, thereby increasing the stability of the structure.

[0042] like Figure 2 and Figure 6 As shown, the outer side surface of the first connecting seat 21 is concavely provided with a plurality of first assembly channels 211, and the first assembly channels 211 are evenly arranged around the rotation axis. The first support seat 512 is extended outward from the outer side wall of the first sleeve 511 along the outer peripheral side of the first sleeve 511. The first support seat 512 is penetrated by a plurality of first matching channels 516 arranged corresponding to the first assembly channels 211. The first connecting seat 21 and the first support seat 512 are matched with the corresponding first assembly channels 211 and the first matching channels 516 through a first assembly piece (not shown in the figure). The long tube connector 51 can be detachably connected in the matching channel 516 to fix the first connecting seat 21. When rotating, the long tube connector 51 and the first connecting seat 21 rotate synchronously. The second matching channel 515 and the first matching channel 516 are staggered. The second support seat 513 is penetrated by a plurality of assembly channels 517 for loading and unloading the first assembly part (not shown in the figure) arranged corresponding to the first matching channel 516, so that tools can be inserted during assembly to increase the practicality of the structure. The first assembly part can be set as a fixing part such as a nut, a screw, and a pin.

[0043] like Figure 7-Figure 9 As shown, the assembly channel 517 is arranged near the outer periphery of the second support seat 513, and a notch is provided on the outer periphery of the second support seat 513 to connect to the assembly channel 517, so that tools can be inserted for easy assembly, thereby increasing the practicality of the structure. Reinforcement ribs are also provided under the notch to consolidate the structural strength and stabilize the structure of the first sleeve 511. The second sleeve 521 is inserted into the first sleeve 511 and rotatably connected to the first sleeve 511. The outer sleeve 521 is provided with one or more sealing rings (not shown in the figure) arranged between the second sleeve 521 and the first sleeve 511, so that the water or other liquid flowing between the two water pipe connectors will not leak, thereby avoiding liquid erosion of functional components and extending the service life of the hose reel.

[0044] like Figure 7-11 As shown, the outer side surface of the second support seat 513 protrudes from the outer side surface of the first sleeve 511, and the inner side surface of the fixing portion 533 is provided with a groove structure 536. When the long tube connector 51 is connected to the short tube connector 52, the inner side surface of the first limit seat 523 abuts against the outer side surface of the second sleeve 521. The second support seat 513 is arranged in the groove structure 536, and the short tube connector 52 can be positioned through the groove structure 536. When the long tube connector 51 and the support limit member 53 are installed, they can rotate in the groove structure 536, which is convenient for the second assembly part (not shown in the figure) to find the corresponding channel more conveniently during the assembly process with the corresponding second assembly channel 535 and the second matching channel 515, and can reduce displacement deviation under the action of hydraulic pressure to prevent leakage.

[0045] like Figure 10 As shown, the support and stopper 53 is provided with a sleeve channel 537 and a mounting channel 538. The second sleeve 521 is rotatably mounted in the sleeve channel 537, so that the short tube connector 52 does not need to rotate when the support and stopper 53 and the long tube connector 51 rotate, and the support and stopper 53 and the long tube connector 51 rotate around the short tube connector 52 without deviation. The mounting channel 538 extends from the outer peripheral side of the support and stopper 53 to the mounting channel 538 and is connected to the mounting channel 538. The second sleeve 521 can extend into the sleeve channel 537 along the mounting channel 538, facilitating the connection between the second sleeve 521 and the support and stopper 53 and increasing practicality.

[0046] like Figure 10 As shown, the channel width of one end of the installation channel 538 connected to the sleeve channel 537 is smaller than the diameter of the sleeve channel 537, and the diameter of the second sleeve 521 is consistent with the sleeve channel 537, so that the first sleeve 511 can be installed in the limited sleeve channel 537 and will not separate from the installation channel 538. The installation channel 538 has a first side wall 54 and a second side wall 55 arranged relatively to each other. The distance between the first side wall 54 and the second side wall 55 gradually increases from one end close to the installation channel 538 to the end close to the outer peripheral side of the support limit member 53. In this embodiment, the support limit member 53 is a plastic part with a certain deformation ability. The setting of the first side wall 54 and the second side wall 55 can facilitate the installation of the second sleeve 521 and the sleeve channel 537, thereby increasing the practicality of the structure.

[0047] like Figure 9 and Figure 11 As shown, a second limit seat 525 is provided on the outer circumference of the second sleeve 521, and the second limit seat 525 is arranged at intervals on the outside of the first limit seat 523. The support limit member 53 is limited between the first limit seat 523 and the second limit seat 525, so that after the second sleeve 521 is sleeved with the first sleeve 511, it is fixed by the first and second limit seats and the support limit member 53 so that it will not undergo axial displacement under the pressure of the water flow. A plurality of sealing grooves 528 for storing sealing rings are provided on the lower side of the second limit seat 525 to position the sealing ring, reduce displacement deviation under the action of hydraulic pressure, prevent liquid leakage, and increase the resistance between the first sleeve 511 and the second sleeve 521 to prevent separation.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.

[0049] In short, the above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
