Description

Technical Field

[0001] The utility model relates to the technical field of garden water pipes, in particular to a hose rotating sheath. Background Art

[0002] In modern landscaping and agricultural irrigation, water pipes (a type of hose) are widely used, and they are key tools for watering and spraying large areas. The traditional hose design usually includes a long flexible pipe, one end of which is connected to the water source, and the other end is equipped with a water gun head to control the spraying mode and range of the water flow. The water gun head is fixed to the end of the water pipe by threads or other forms of mechanical connection. Although this design is simple, it has some inconveniences in actual operation.

[0003] First, due to the flexibility of the hose itself, when the user moves the hose or adjusts the spraying direction, the hose is prone to curling and bending. This curling and bending may not only block the water flow inside the hose, affecting the spraying effect, but also increase the resistance when the user drags the hose, making the operation more laborious. This inconvenience is particularly obvious when the hose needs to be moved over a long distance or operated on uneven ground.

[0004] Secondly, although the connection between the water gun head and the water pipe ensures the stability of the connection, if the water pipe is twisted too much, this fixed connection method is not flexible enough when the spraying angle and direction need to be adjusted frequently. Users often need to rotate or swing the water gun head with force to achieve the ideal spraying effect, which increases the complexity and labor intensity of the operation to a certain extent.

[0005] Therefore, it is necessary to further improve and perfect the prior art to overcome these deficiencies, and the present invention is made based on this situation. Utility Model Content

[0006] The utility model aims to overcome the deficiencies of the prior art and provide a hose rotating sheath which is convenient to drag and use.

[0007] The utility model is realized by the following technical solutions:

[0008] In order to solve the above technical problems, the utility model provides a hose rotating sheath, comprising an inner tube and an outer tube, one end of the inner tube is connected to a hose, the other end of the inner tube is provided with a connector that can be connected to a water gun nozzle, the outer tube is sleeved on the inner tube and the two are rotatably connected.

[0009] In order to further solve the technical problem to be solved by the utility model, in a hose rotating sheath provided by the utility model, an upper limit protrusion and a lower limit protrusion are respectively provided on the outer side wall of the inner tube, and an upper positioning step and a lower positioning step are respectively provided on the inner side wall of the outer shell, the upper positioning step cooperates with the upper limit protrusion from below, and the lower positioning step cooperates with the lower limit protrusion from above, thereby forming an axial limit and a circumferential rotation connection between the outer shell and the inner tube.

[0010] In order to further solve the technical problem to be solved by the utility model, in a hose rotating sheath provided by the utility model, a first guiding inclined surface is provided on the upper side of the upper positioning step, and a second guiding inclined surface is provided on the upper side of the lower positioning step.

[0011] In order to further solve the technical problem to be solved by the utility model, in a hose rotation sheath provided by the utility model, the outer diameter R of the upper limit protrusion is greater than the outer diameter r of the lower limit protrusion.

[0012] In order to further solve the technical problem to be solved by the utility model, the utility model provides a hose rotating sheath, in which a rigid sheath is sleeved on one end of the hose connected to the inner tube.

[0013] In order to further solve the technical problem to be solved by the utility model, in a hose rotating sheath provided by the utility model, the rigid sheath is a copper leather sheath.

[0014] In order to further solve the technical problem to be solved by the utility model, in a hose rotating sheath provided by the utility model, a plurality of annular ridges for reducing the contact area between the inner tube and the outer sheath are provided on the outer side wall of the inner tube.

[0015] In order to further solve the technical problem to be solved by the utility model, the utility model provides a hose rotating sheath, in which one end of the connector is fixedly fitted on the inner tube, and the other end of the connector is provided with a male thread or a female thread that can be threadedly connected to the water gun nozzle.

[0016] In order to further solve the technical problem to be solved by the utility model, in a hose rotating sheath provided by the utility model, a flexible anti-slip sheath is provided on the outer sheath.

[0017] In order to further solve the technical problem to be solved by the utility model, the utility model provides a hose rotating sheath, in which the upper end of the inner tube extends out of the upper end of the outer sleeve.

[0018] Compared with the prior art, the utility model has the following advantages:

[0019] 1. The outer sleeve is mounted on the inner tube and the two are rotationally connected. In this rotational connection mechanism, when the hose is subjected to a twisting force, the inner tube can rotate freely relative to the outer sleeve. This rotational action helps to release the accumulated twisting force and prevent the hose from being damaged due to excessive twisting. This design not only reduces the extra burden on the user during operation, but also greatly extends the service life of the hose. In addition, this automatic rotation to relieve twisting also improves the overall efficiency of the hose system. In traditional non-rotating hose designs, twisting often leads to obstructed water flow, reduced water pressure and flow rate, and affected the spraying effect of the water gun nozzle. Through this automatic rotation mechanism, the hose can always maintain the best water flow state, ensuring that the water gun nozzle can achieve maximum spraying efficiency.

[0020] 2. By setting upper and lower limit protrusions on the outer wall of the inner tube, and upper and lower positioning steps on the inner wall of the outer shell, these steps cooperate with the protrusions on the inner tube to ensure the precise alignment between the inner tube and the outer shell. This design enables the outer shell to rotate closely around the inner tube, ensuring the stability and reliability of the rotation, while maintaining axial stability.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figures 1 to 4 The hose rotating sheath shown in the figure comprises an inner tube 1 and an outer tube 2. One end of the inner tube 1 is connected to a hose 3 (the hose 3 usually refers to a water pipe, and is also applicable to the field of hoses such as air pipes) through a stable connection method to ensure unimpeded water flow. The other end is equipped with a connector 4, which can be seamlessly connected to the water gun nozzle, so that the water gun nozzle can be easily installed and remain stable.

[0028] The design of the outer cover 2 is the key to the utility model. The outer cover 2 is sleeved on the inner tube 1 and the two are rotatably connected. This rotatable connection mechanism allows the outer cover 2 to rotate freely relative to the inner tube 1, so that when the user operates the hose, the curling and bending of the hose can be effectively reduced, and the continuity and stability of the water flow can be maintained. In addition, this rotation design also greatly reduces the friction resistance of the hose during movement, making it easier to drag the hose.

[0029] When the user needs to move or adjust the position of the hose, he or she only needs to hold the outer sleeve 2 and drag it. During the dragging process, if the hose is twisted, this design allows the inner tube 1 to automatically rotate under the action of the twisting force, thereby effectively releasing the twisted state.

[0030] In addition, when the user needs to adjust the spraying direction, if the hose is twisted too much, the rotation function of the outer cover 2 allows the water gun nozzle to rotate and swing freely without the user having to twist or adjust it hard, thereby greatly simplifying the operation process and reducing the labor intensity of the user. This design not only improves the convenience of operation, but also enhances the accuracy and efficiency of spraying.

[0031] More specifically, the above-mentioned rotational connection is as follows: Two key structures are provided on the outer wall of the inner tube 1: an upper limit protrusion 11 and a lower limit protrusion 12. The design of these two protrusions not only ensures the correct alignment between the inner tube 1 and the outer sleeve 2, but also provides the necessary axial limit to prevent unnecessary axial movement during the rotation process. An upper positioning step 21 and a lower positioning step 22 are correspondingly provided on the inner wall of the outer sleeve 2. The upper positioning step 21 cooperates with the upper limit protrusion 11 from below, while the lower positioning step 22 cooperates with the lower limit protrusion 12 from above. This matching design enables the outer sleeve 2 to rotate tightly around the inner tube 1 while maintaining axial stability.

[0032] More specifically, in order to ensure the convenience and accuracy of assembly, a first guiding slope 23 is provided on the upper side of the upper positioning step 21, and a second guiding slope 24 is provided on the upper side of the lower positioning step 22. The design of these guiding slopes not only helps to guide the correct alignment of the outer sleeve 2 and the inner tube 1 during the installation process, but also reduces the resistance during installation, so that the outer sleeve 2 can slide onto the inner tube 1 more smoothly.

[0033] In addition, in order to further simplify the assembly process, the outer diameter R of the upper limit protrusion 11 is designed to be larger than the outer diameter r of the lower limit protrusion 12. This design allows the outer sleeve 2 to be easily inserted into the inner tube 1 from bottom to top during installation.

[0034] More specifically, the end of the hose 3 connected to the inner tube 1 is covered with a rigid sheath 5. Its main purpose is to protect the hose 3 from external damage and provide a strong connection point. Preferably, the rigid sheath 5 is a copper sheath. In addition, the design of the rigid sheath 5 allows it to be riveted to the inner tube 1.

[0035] More specifically, in order to optimize the rotation performance and reduce friction between the inner tube 1 and the outer tube 2, the utility model provides a plurality of annular ridges 13 on the outer wall of the inner tube 1. The ridges 13 are designed to reduce the direct contact area between the inner tube 1 and the outer tube 2, thereby reducing the friction resistance during rotation.

[0036] In addition, the presence of the ridges 13 also helps prevent adhesion between the outer sleeve 2 and the inner tube 1, which may cause rotation difficulties, especially in long-term use or high humidity environments. By reducing the contact area, the ridges 13 effectively prevent this from happening, ensuring the long-term stable operation of the hose system.

[0037] It is worth noting that, thanks to the ingenious rotating connection structure designed between the outer sleeve 2 and the inner tube 1, this design ensures that there will be no interference or influence on the connector 4 during the rotation process. Therefore, the design of the connector 4 can flexibly adopt a variety of structural forms and specifications to meet different application requirements.

[0038] In this embodiment, one end of the connector 4 is firmly mounted on the inner tube 1 by a fixed fit (such as an interference fit, a snap fit, etc.), and this fixing method ensures that the connector 4 is stable and reliable and is not easy to loosen or fall off. The other end of the connector 4 is designed to have a universal connection structure, which can be threadedly connected with various types of water gun nozzles. Specifically, the end of the connector 4 is provided with a male thread 41 or a female thread, which enables it to flexibly match water gun nozzles of different specifications.

[0039] More specifically, in order to enhance the comfort and safety of the user during operation, a flexible anti-skid cover 6 is provided on the outer cover 2. The anti-skid cover 6 is preferably a rubber cover. The main function of the anti-skid cover 6 is to provide a better grip and anti-skid effect when the user holds the hose for operation, ensuring that the hose can be stably controlled in various environments.

[0040] More specifically, the upper end of the inner tube 1 extends out of the upper end of the outer sleeve 2 to facilitate the disassembly and assembly of the connector 4 or the water gun nozzle.
