Description

Technical Field

[0001] This utility model relates to the field of kitchen and bathroom technology, and in particular to an anti-disassembly flexible hose and a disassembly component. Background Technology

[0002] Shower heads and their inlet hoses are generally assembled with threads and can be disassembled and replaced. However, in some places, such as guesthouses, managers want shower heads and their inlet hoses to have anti-disassembly functions. Currently, there are some hoses on the market with anti-disassembly features, but these hoses have complex structures or are not easy for managers to disassemble. Therefore, this utility model provides an anti-disassembly structure for hoses, which can solve the above-mentioned technical problems. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model proposes an anti-disassembly structure for shower hoses, which can prevent the shower head from being disassembled at will.

[0004] An anti-tamper hose includes a hose, a nut, and a disassembly component, wherein,

[0005] The nut is generally trumpet-shaped and is used with commercially available shower head sockets, thus providing versatility for this anti-tamper structure. The nut includes a nut body and a shell. The nut body is rotatably mounted on the end of the hose, and the shell is rotatably mounted on the outer periphery of the nut body, covering the outer periphery of the nut body and concealing it. The end of the nut body that is fitted onto the hose has a positioning groove; alternatively, the shell may also cover the end of the nut body and have a clearance opening corresponding to the positioning groove.

[0006] This utility model disassembles the nut into a nut body and a shell that can rotate relative to each other, and sets a positioning groove and a clearance opening between the nut body and the shell. During disassembly and assembly, a disassembly part with an insertion part can be used. The insertion part is inserted into the positioning groove, and the disassembly part drives the nut body to rotate through the insertion part and the positioning groove. Alternatively, the insertion part is inserted into the positioning groove through the clearance opening, and the nut body and the shell are relatively fixed in the direction of rotation through the insertion part. Thus, the nut body can be rotated by rotating the shell. After assembly, the disassembly part can be retracted, and the shell and the nut body return to a state of relative free rotation, which can prevent the shower head from being removed. The overall structure is simple and has the advantage of being convenient for managers to use.

[0007] Preferably, there are at least two sets of positioning grooves and clearance openings, and correspondingly, at least two insertion parts. On the one hand, this improves the limiting effect of the disassembly component on the outer shell and the nut body. On the other hand, it can also disperse the shearing force of the positioning grooves and clearance openings on a single insertion part, thus preventing the disassembly component from being easily damaged.

[0008] Preferably, the outer shell is made of metal, which is hard and solid, and can prevent the nut body from being moved by squeezing the outer shell.

[0009] Preferably, the end of the hose is rotatably mounted inside the nut body, thereby avoiding the situation where the hose is twisted and the nut body is disassembled.

[0010] Preferably, the nut body has an installation groove, and the groove opening has a stepped groove. A limiting ring is provided on the outer periphery of the hose end, the thickness of which is less than or equal to the depth of the installation groove. The limiting ring is rotatably disposed within the installation groove, and the hose end extends into the stepped groove. A pressure ring is provided within the stepped groove, the thickness of which is greater than the depth of the groove. The pressure ring is fitted around the outer periphery of the hose end, and a sealing ring is provided between it and the hose end. When the shower head and nut are assembled together, the shower head end presses the pressure ring tightly into the stepped groove, while the pressure ring and limiting ring are not compressed together, and a sealing ring is also present between the pressure ring and the hose. Therefore, the hose can rotate freely without leaking water.

[0011] Preferably, the pressure ring has an annular groove facing the outer periphery of the limiting ring and the hose, and the sealing ring is installed in the annular groove. A filter screen is also placed on top of the pressure ring to improve water quality.

[0012] Preferably, the tamper-proof hose further includes a disassembly component, which is provided with an insertion positioning groove or a clearance port for insertion into the positioning groove.

[0013] Secondly, a disassembly component is also provided for the installation and disassembly of the anti-disassembly hose and shower head described in the first aspect. The disassembly component has an insertion part. When disassembling or installing the nut and shower head, the insertion part is inserted into a positioning groove. The disassembly component drives the nut body to rotate through the insertion part and the positioning groove. Alternatively, the insertion part is inserted into the positioning groove through a clearance opening. The nut body and the outer shell are relatively fixed in the direction of rotation through the insertion part, thereby enabling the nut body to rotate by rotating the outer shell. When the disassembly component is retracted, i.e., the insertion part exits the positioning groove and clearance opening, rotating the outer shell prevents the nut body from rotating, thus achieving the purpose of preventing disassembly.

[0014] Preferably, the disassembly component is also provided with a handle to facilitate its use.

[0015] Preferably, the handle is perpendicular to the axis of the nut. When the user uses the disassembly component, the handle can be used to hold the disassembly component in place, preventing it from falling off.

[0016] Preferably, there are two sets of positioning grooves and clearance openings, symmetrically distributed on both sides of the nut. The disassembly component has a semi-circular collar, and there are also two insertion parts, respectively disposed at both ends of the collar. In use, the disassembly component is fitted onto the outer periphery of the hose through the collar, forming a stable and reliable support and improving ease of use.

[0017] As can be seen from the above description of this utility model, this utility model has the following beneficial effects:

[0018] This utility model disassembles the nut into a nut body and a shell that can rotate relative to each other, and sets a positioning groove at the end of the nut body, or sets a relative positioning groove and clearance opening between the nut body and the shell. During disassembly and assembly, a disassembly part with an insertion part can be used to drive the nut body to rotate. After assembly, the disassembly part can be put away, and the shell and the nut body can be restored to a relatively flexible rotation state, which can prevent the shower head from being removed. The overall structure is simple and has the advantage of being convenient for managers to use.

[0019] The nut is flared in shape and is compatible with common shower head sockets on the market, thus providing the versatility of the anti-disassembly structure.

[0020] The end of the hose is rotatably installed inside the nut body, thereby avoiding the situation where the hose is twisted and the nut body is disassembled.

[0021] It is also equipped with a disassembly part, which is provided with a handle for easy use;

[0022] The positioning groove, the clearance opening, and the insertion part are in at least two sets. On the one hand, this improves the limiting effect of the disassembly part on the outer shell and the nut body. On the other hand, it can also disperse the shearing force of the positioning groove and the clearance opening on a single insertion part, thus preventing the disassembly part from being easily damaged.

[0023] The disassembly component is equipped with a collar that can be fitted onto the outer periphery of the hose to form a stable and reliable support, thereby improving ease of use. Attached Figure Description

Detailed Implementation

[0036] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0037] Please see Figures 1 to 8 An anti-tamper hose 1 includes a hose 1 and a nut 2, wherein,

[0038] Preferably, the nut 2 is flared in shape and is used in conjunction with commercially available shower head sockets, thereby providing the versatility of the anti-disassembly structure.

[0039] The nut 2 includes a nut body 21 and a shell 22. Preferably, the shell 22 is made of metal, which is hard and solid, and can prevent the nut body 21 from being moved by squeezing the shell 22.

[0040] The nut body 21 is rotatably mounted on the end of the hose 1, and the outer shell 22 is rotatably mounted on the outer periphery of the nut body 21, covering the outer periphery of the nut body 21 and concealing it. A positioning groove 211 is provided at the end of the nut body 21 that is fitted onto one end of the hose 1. When assembling or disassembling the tamper-proof hose, a disassembly piece 3 equipped with an insertion part 31 can be used. The insertion part 31 is inserted into the positioning groove 211, allowing the user to rotate the disassembly piece 3 to rotate the nut body 21, thereby assembling or disassembling the nut 2.

[0041] Alternatively, in another embodiment, please refer to Figure 9 The outer shell 22 also covers the end of the nut body 21, and the outer shell 22 is provided with a clearance opening 221 corresponding to the positioning groove 211. When disassembling or assembling the tamper-proof hose, a disassembly piece 3 equipped with an insertion part 31 can be used. The insertion part 31 is inserted into the clearance opening 221 and the positioning groove 211 in sequence, so that the user can rotate the disassembly piece 3 to drive the rotation of the nut body 21, thereby realizing the disassembly or assembly of the nut 2.

[0042] Based on the above embodiments, the end of the hose 1 is rotatably mounted inside the nut body 21, thereby preventing the hose 1 from being twisted and causing the nut body 21 to be disassembled. Preferably, the nut body 21 is provided with a mounting groove 212, and the opening of the mounting groove 212 is provided with a stepped groove 213. A limiting ring 11 is provided on the outer periphery of the end of the hose 1, and the thickness of the limiting ring 11 is less than or equal to the depth of the mounting groove 212. The limiting ring 11 is rotatably disposed in the mounting groove 212, and the end of the hose 1 extends into the stepped groove 213. A pressure ring 4 is provided in the stepped groove 213. The thickness of the pressure ring 4 is greater than the depth of the stepped groove 213. The pressure ring 4 is sleeved on the outer periphery of the end of the hose 1, and a sealing ring 5 is provided between the pressure ring 4 and the outer periphery of the end of the hose 1. When the shower head and the nut 2 are assembled together, the end of the shower head presses the pressure ring 4 into the stepped groove 213. However, the pressure ring 4 is not pressed against the limiting ring 11, and there is a sealing ring 5 between the pressure ring 4 and the hose 1. Thus, the hose 1 can not only rotate freely, but also will not leak water.

[0043] For the installation structure of the sealing ring 5, preferably, the pressure ring 4 has an annular groove facing the outer periphery of the limiting ring 11 and the hose 1, and the sealing ring 5 is installed in the annular groove. A filter screen 6 is also placed on top of the pressure ring 4 to improve water quality.

[0044] In another embodiment, a disassembly component 3 is also provided, which has an insertion part 31. When the nut 2 is disassembled or installed from the shower head, the insertion part 31 is inserted into the positioning groove 211, or inserted into the positioning groove 211 through the clearance opening 221. This allows the nut body 21 to rotate by rotating the disassembly component 3. When the disassembly component 3 is retracted, the nut body 21 cannot rotate when the outer casing 22 is rotated, thereby achieving the purpose of preventing disassembly.

[0045] Preferably, there are two positioning grooves 211, or at least two sets of positioning grooves 211 and clearance openings 221. Correspondingly, there are also at least two insertion parts 31. On the one hand, this improves the limiting effect of the disassembly component 3 on the outer shell 22 and the nut body 21. On the other hand, it can also disperse the shearing force of the positioning grooves 211 and clearance openings 221 on a single insertion part 31, preventing the disassembly component 3 from being easily damaged. For example, in a specific embodiment, there are two positioning grooves 211, which are symmetrically distributed on both sides of the nut 2. In addition, the disassembly component 3 is provided with a semi-circular collar 32, and there are also two insertion parts 31, which are respectively provided at both ends of the collar 32. In use, the disassembly component 3 is sleeved on the outer periphery of the hose 1 through the collar 32, forming a stable and reliable support and improving the convenience of use.

[0046] In one embodiment, the disassembly component 3 is further provided with a handle 33 to facilitate its use. Preferably, the handle 33 is perpendicular to the axial direction of the nut 2. When the user uses the disassembly component 3, the handle 33 can be used to hold the disassembly component 3 in place, preventing it from falling off.

[0047] This utility model disassembles the nut 2 into a nut body 21 and a shell 22 that can rotate relative to each other. A positioning groove 211 is provided in the nut body 21, or a positioning groove 211 and a clearance opening 221 are provided between the nut body 21 and the shell 22. During disassembly and assembly, the insertion part 31 of the provided disassembly part 3 can be inserted into the positioning groove 211, thereby rotating the nut body 21 together by rotating the disassembly part 3. After assembly, the disassembly part 3 can be retracted, and the shell 22 and the nut body 21 return to a state of relative rotation, which can prevent the shower head from being removed. The overall structure is simple and has the advantage of being convenient for managers to use.
