Description

Technical Field

[0001] The present application relates to the technical field of hose reels, and in particular to a hose reel with flexible winding capabilities. Background Art

[0002] At present, in some high-pressure cleaning machines, or in some places where water pipes need to be reeled up, a hose reel is needed to reel up the water pipes. If the water pipes are piled up on the ground in a disorderly manner, it is easy to trip. If the flexible water pipes are dragged on the ground, the outer surface of the water pipes is easy to wear. For the staff, it is necessary to pull the water pipes, so a hose reel is needed to collect the water pipes.

[0003] For example, Chinese patent document CN212923904U discloses a water pipe storage device. The device passes one end of the water pipe through two cylindrical sleeves and fixes it on a winding rod. The manual turntable drives the rotating shaft to rotate, thereby driving the winding rod to wind up the water pipe. This structure is bulky and the winding is not flexible.

[0004] Therefore, a new structure needs to be designed, and the problem that needs to be solved is: how to design a new flexible reel. Utility Model Content

[0005] In view of the above-mentioned shortcomings (problems) of the prior art, in order to achieve flexible winding of the water pipe for ease of use, the present application provides a flexible winding hose reel.

[0006] To achieve the above objectives and other related objectives, this application adopts the following technical solutions:

[0007] A flexible hose reel comprises a shell, only one side of which is open, a valve cover is arranged on the outer side of the middle part of the shell, a water pipe is sealed and rotatably connected to the valve cover, a lining plate is sleeved on the valve cover, the lining plate is fixed on the inner side of the shell, and a ratchet is connected to the inner side of the shell through a tension spring;

[0008] The valve cover is fixed to one end of the valve body, and the other end of the valve body is sleeved with a spring core, and a reel is also sleeved on the valve body. A through hole is provided at the shaft of the reel, and a water pipe joint is provided on the valve body. The water pipe joint passes through the through hole and is connected to a hose, and the hose is wound and rolled on the reel;

[0009] A coil spring is accommodated on one side of the reel, one end of the coil spring is fixed on the reel, the other end of the coil spring is fixed on the spring valve core, and a semi-ring tooth plate is fixed on the other side of the reel, and the tooth plate is in contact with the ratchet.

[0010] Preferably, the reel comprises two halves of identical shape, each of which comprises an annular edge portion, a shaft neck portion and a bottom plate portion, the shaft neck portion receiving an inner ring of the annular edge portion and an outer ring of the bottom plate portion, a through hole being arranged on the shaft neck portion, and the bottom plates of the two halves being fixedly connected back to back.

[0011] Preferably, a shaft is provided on the valve body, the shaft forms a step surface on the valve body, and the bottom plates of the two half bodies are fixed on the step surface of the valve body.

[0012] Preferably, a tool groove is provided at the axial center position of the outer end of the spring core, a clamping groove for fixing the coil spring is provided on the peripheral surface, and the spring core is fixedly connected with the shaft rod through threads.

[0013] Preferably, one end of the tension spring is fixed on the lining plate, and the other end of the tension spring is fixed on the tail of the ratchet for resetting the ratchet.

[0014] Preferably, the tooth plate is provided with a plurality of tooth grooves, and the ratchet is engaged with the tooth grooves to limit the reverse rotation of the tooth plate and allow the tooth plate to rotate forward.

[0015] Preferably, the valve cover is provided with multiple layers of sealing grooves, and water openings are provided between the sealing grooves.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] The normally open side of the shell is reserved for the hose to be pulled and reeled. Initially, the reel reels up the hose to prevent the hose from being too long. When in use, the hose is pulled, and the reel will rotate to send out more hose. Then the coil spring is charged and accumulates elastic potential energy. Due to the cooperation between the ratchet and the toothed plate on the reel, the reel and the ratchet are locked. In this way, even if the coil spring accumulates elastic potential energy, the length of the pulled hose can be kept unchanged, making it more convenient to use. Then, the hose continues to be pulled. Since the toothed plate is semi-annular, when it is disengaged from the engagement of the ratchet, the hose is released. Under the action of the coil spring, the coil spring resets the reel, so that the reel automatically reels up the hose again. During the above-mentioned operation and use, the water pipe transports water through the valve cover, the valve body and then to the hose. This process is sealed and leak-proof.

[0026] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0027] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The illustrations only show the components related to the present application rather than being drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0028] The specific implementation methods of the present application will be further described below in conjunction with the accompanying drawings. Example

[0029] The present application discloses a flexible reel for reeling, referring to Figure 1 As shown, it includes a housing 1, with only one side of the housing 1 being open. The housing 1 is a sheet metal part, which can be composed of a cover plate and a box body to form a square structure, which is convenient for reliable placement and installation. The box body can protect the internal hose 100 from being easily bumped.

[0030] Combination Figure 2 and Figure 3 It is understood that a valve cover 2 is arranged outside the middle of the housing 1, a water pipe 3 is sealed and rotatably connected to the valve cover 2, a lining plate 4 is sleeved on the valve cover 2, the lining plate 4 is fixed to the inner side of the housing 1, and a ratchet 6 is connected to the inner side of the housing 1 through a tension spring 5. This structure can also be referred to FIG. Figure 5 and Figure 6The valve cover 2 is provided with multiple sealing grooves 21, and water ports 22 are provided between the sealing grooves 21. A sealing ring is provided in the sealing groove 21 to achieve a reliable sealing effect. Since the water pipe 3 is rotatably connected to the valve cover 2, water can flow in from the water port 22. The water pipe 3 is different from the faucet connected externally (through a water pipe, etc.), and the valve cover 2 can be rotated.

[0031] The valve cover 2 is fixed to one end of the valve body 130, and the other end of the valve body 130 is sleeved with a spring core 7, and the valve body 130 is also sleeved with a reel 8, and the shaft of the reel 8 is provided with a through hole 814, and the valve body 130 is provided with a water pipe joint 9, which passes through the through hole 814 and is connected with a hose 100, and the hose 100 is wound and rolled on the reel 8. In this way, the valve cover 2, the valve body 130, the reel 8, the water pipe joint 9, and the spring core 7 are fixed to each other, so that they can rotate together.

[0032] A coil spring 110 (metal spring) is housed on one side of the reel 8 , one end of the coil spring 110 is fixed to the reel 8 , and the other end of the coil spring 110 is fixed to the spring valve core. A semi-ring tooth plate 120 is fixed to the other side of the reel 8 , and the tooth plate 120 is in contact with the ratchet 6 .

[0033] The working results are as follows:

[0034] The normally open side of the housing 1 is used for the hose 100 to be pulled and reeled. Initially, the reel 8 reels the hose 100 to prevent the hose 100 from being too long. When in use, the hose 100 is pulled, and the reel 8 rotates to deliver more hose 100. Then, the coil spring 110 is charged and accumulates elastic potential energy. Due to the cooperation between the ratchet 6 and the tooth plate 120 on the reel 8, the reel 8 and the ratchet 6 are locked. In this way, even if the coil spring 110 accumulates elastic potential energy, It is also possible to keep the length of the pulled hose 100 unchanged, making it more convenient to use; then, the hose 100 continues to be pulled, and since the tooth plate 120 is a semi-ring, when it is disengaged from the engagement of the ratchet 6, the hose 100 is released, and under the action of the coil spring 110, the coil spring 110 resets the reel 8, so that the reel 8 automatically rewinds the hose 100; during the above-mentioned operation and use process, the water pipe 3 transports water through the valve cover 2, the valve body 130 and then to the hose 100, and this process is sealed and watertight.

[0035] In order to facilitate assembly and production, Figure 3As can be seen in the figure, the reel 8 includes two half bodies 81 of the same shape, the half body 81 includes a ring edge portion 811, a shaft neck portion 812 and a bottom plate portion 813, the shaft neck portion 812 receives the inner ring of the ring edge portion 811 and the outer ring of the bottom plate portion 813, the through hole 814 is provided on the shaft neck portion 812, and the bottom plates 813 of the two half bodies 81 are fixedly connected back to back. In this way, the production and manufacturing of the reel 8 is very easy, and stamping can be adopted. At the same time, the half body 81 can accommodate the coil spring 110, so that the overall structure is more compact.

[0036] In order to make the reel 8 more reliably assembled, a shaft 131 is provided on the valve body 130, and the shaft 131 forms a step surface 132 on the valve body 130, and the bottom plates of the two half bodies 81 are fixed on the step surface 132 of the valve body 130. In this way, the reel 8 formed by the two half bodies 81 can allow the hose 100 to be wound several more times.

[0037] In order to facilitate assembly, a tool groove 71 is provided at the outer end of the spring core 7, and the tool groove 71 is a hexagonal groove, which can be rotated with a hexagonal tool (for easy assembly and disassembly). A clamping groove 72 for fixing the coil spring 110 is provided on the peripheral surface, and the spring core 7 is threadedly connected and fixed to the shaft 131. This makes the assembly convenient and firm.

[0038] In order to make the ratchet 6 work reliably, one end of the tension spring 5 is fixed to the lining plate 4, and the other end of the tension spring 5 is fixed to the tail of the ratchet 6 for resetting the ratchet 6. The function of the tension spring 5 is to reset the ratchet 6. In order to be able to rotate, the ratchet 6 is realized by a pin shaft, and the pin shaft is fixed to the housing 1.

[0039] Finally, the tooth plate 120 is provided with a plurality of tooth grooves 121, and the ratchet 6 is engaged with the tooth grooves 121 to limit the reverse rotation of the tooth plate 120 and allow the tooth plate 120 to rotate forward. This design allows the hose 100 to be self-locked by the ratchet 6 after being pulled out. At the same time, it can also be unlocked, that is, the reel 8 continues to rotate unidirectionally, and after being disengaged from the ratchet 6, under the action of the coil spring 110, the reel 8 is reset at a certain speed, so that the ratchet 6 cannot be engaged with the tooth groove 121.

[0040] It can be seen that the user can store the hose 100 conveniently, the operation is convenient and labor-saving, and the service life is long. It is also convenient for factory manufacturing and labor-saving in inspection and maintenance.

[0041] The above embodiments are only illustrative of the principles and effects of the present application, and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application shall be included in the protection scope of the present application.
