Description

Technical Field

[0001] The utility model belongs to the technical field of bathroom product accessories, and more specifically relates to a hose anti-winding structure. Background Art

[0002] Since both ends of the traditional hose are fixed, they are prone to entanglement during use, which not only affects the service life of the hose but also causes inconvenience to users.

[0003] An anti-tangle hose has appeared on the market, which has rotatable joints at both ends of the hose. In the prior art, an anti-tangle hose similar to the above-mentioned one will cause the rotatable joint to stick to the connector when the water pressure in the hose pipe increases, making it impossible for the hose to rotate on the connector. Therefore, a hose anti-tangle structure is needed to solve the above problem. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present invention aims to provide a hose anti-winding structure, which has the advantage of preventing the hose from rotating due to increased water pressure.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A hose anti-winding structure includes a connector threadedly connected to a shower head and a rotating assembly connected to the hose and located inside the connector, wherein a supporting steel sheet for supporting the rotating assembly is installed in the connector, and the rotating assembly includes a spinning core and a spinning pressure cover, the spinning pressure cover is located above the supporting steel sheet and abuts against the supporting steel sheet, and the supporting steel sheet is sleeved on one end of the spinning core, the spinning core is rotatably installed in the spinning pressure cover, and an annular groove and a groove 1 are opened on the spinning pressure cover, and a first sealing ring and a second sealing ring are respectively installed in the annular groove and the groove 1, and the second sealing ring is sleeved on the outer wall of the spinning core.

[0007] The advantages of this solution are at least that: when the connector is in use, the water pressure in the hose presses the first sealing ring downward, thereby increasing the sealing between the rotating assembly and the connector, and at the same time, under the action of the water pressure, the self-spinning cover is pressed against the supporting steel sheet. At this time, the second sealing ring is also affected by the water pressure, so that the second sealing ring increases the sealing between the self-spinning cover and the self-spinning core. Since the self-spinning core is rotatably installed in the self-spinning cover, the self-spinning core is not affected when the water pressure increases, and therefore can also drive the hose to rotate on the connector, thereby avoiding the hoses from being entangled. At the same time, the setting of the rotating assembly also reduces the method of directly connecting the shower head and the connector with a gasket.

[0008] The present invention is further configured as follows: a second groove is provided on the inner side wall of the connector opening, and a third sealing ring is installed in the second groove.

[0009] The advantage of this solution is at least that the third sealing ring increases the sealing between the connector and the shower head, thereby preventing water leakage at the connection.

[0010] The utility model is further configured as follows: a first mounting ring and a second mounting ring are sequentially sleeved on the outer wall of the hose, and the spinning core is tightly attached to one side wall of the first mounting ring and the second mounting ring to connect the hose to the connector.

[0011] The advantage of this solution is at least that the cooperation between the first mounting ring and the second mounting ring increases the connection strength between the hose and the spin core, while beautifying the connection position between the hose and the connector.

[0012] The utility model is further configured as follows: the first sealing ring and the second sealing ring are both V-shaped sealing rings.

[0013] The present invention is further configured such that the openings of the first sealing ring and the second sealing ring are both arranged toward the shower head.

[0014] The utility model is further configured as follows: the spin core and the spin pressure cover are made of copper material.

[0015] The advantage of this solution is at least that the copper spin core and the spin cover have strong corrosion resistance, which can increase the service life of the spin core and the spin cover.

[0016] In summary, the present invention has at least the following advantages:

[0017] 1. By providing a rotating assembly, a first sealing ring, and a second sealing ring, when the connector is in use, the water pressure in the hose presses the first sealing ring downward, thereby increasing the sealing between the rotating assembly and the connector. At the same time, under the action of the water pressure, the self-spinning gland is pressed tightly against the supporting steel sheet. At this time, the second sealing ring is also affected by the water pressure, thereby increasing the sealing between the self-spinning gland and the self-spinning core. Since the self-spinning core is rotatably installed in the self-spinning gland, the self-spinning core is not affected when the water pressure increases, and can also drive the hose to rotate on the connector, thereby preventing the hoses from being entangled. At the same time, the provision of the rotating assembly also reduces the need for a gasket to be directly connected to the shower head and the connector.

[0018] 2. By setting the third sealing ring, the third sealing ring increases the sealing between the connector and the shower head to avoid water leakage at the connection;

[0019] 3. By providing the first mounting ring and the second mounting ring, the cooperation of the first mounting ring and the second mounting ring increases the connection strength between the hose and the spin core, and at the same time beautifies the connection position between the hose and the connector.

DETAILED DESCRIPTION

[0026] The present invention will be described in further detail below with reference to the accompanying drawings.

[0027] A hose anti-winding structure, such as Figure 1 、 Figure 2 As shown, it includes a connector 1 threadedly connected to the shower head 13 and a rotating assembly 2 connected to the hose 4 and located inside the connector 1. A supporting steel sheet 3 for supporting the rotating assembly 2 is installed in the connector 1. The rotating assembly 2 includes a spinning core 201 and a spinning pressure cover 202. The spinning pressure cover 202 is located above the supporting steel sheet 3 and abuts against the supporting steel sheet 3. The supporting steel sheet 3 is sleeved on one end of the spinning core 201, and the spinning core 201 is rotatably installed in the spinning pressure cover 202. Figure 2 、 Figure 3 As shown, a ring groove 5 and a groove 1 6 are provided on the spin cover 202 , a first sealing ring 7 and a second sealing ring 8 are installed in the ring groove 5 and the groove 1 6 respectively, and the second sealing ring 8 is sleeved on the outer wall of the spin core 201 .

[0028] It is worth mentioning that the spin core 201 and the spin cap 202 are made of copper, which has strong corrosion resistance and can increase the service life of the spin core 201 and the spin cap 202.

[0029] like Figure 3 、 Figure 4As shown, in some embodiments, in order to improve the sealing between the self-spinning cover 202 and the connector 1 and between the self-spinning cover 202 and the self-spinning core 201, the first sealing ring 7 and the second sealing ring 8 are preferably V-shaped sealing rings. It is worth mentioning that the openings of the first sealing ring 7 and the second sealing ring 8 are both set towards the direction of the shower head 13. When there is water pressure, the V-shaped sealing ring will be stretched outward under the action of the water pressure, causing the sealing ring to deform, thereby increasing the sealing between the self-spinning cover 202 and the connector 1 and between the self-spinning cover 202 and the self-spinning core 201. A groove 2 9 is provided on the inner side wall of the opening of the connector 1, and a third sealing ring 10 is installed in the groove 2 9.

[0030] like Figure 5 As shown, a first mounting ring 11 and a second mounting ring 12 are sequentially mounted on the outer wall of the hose 4. A spin core 201 is tightly attached to one side of the first and second mounting rings 11 and 12, connecting the hose 4 to the connector 1. The cooperation between the first and second mounting rings 11 and 12 and the spin core 201 increases the connection strength between the hose 4 and the spin core 201, while also beautifying the connection between the hose 4 and the connector 1.

[0031] The working process and beneficial effects of the utility model are as follows:

[0032] When the connector 1 is in use, the water pressure in the hose 4 presses the first sealing ring 7 downward, thereby increasing the sealing between the rotating assembly 2 and the connector 1. At the same time, under the action of the water pressure, the self-spinning cover 202 is pressed against the supporting steel plate 3. At this time, the second sealing ring 8 is also affected by the water pressure, causing the second sealing ring 8 to increase the sealing between the self-spinning cover 202 and the self-spinning core 201. Since the spin core 201 is rotatably installed in the spin cover 202, the spin core 201 is not affected when the water pressure increases. Therefore, it can also drive the hose 4 to rotate on the connector 1, thereby preventing the hose 4 from being entangled. At the same time, the arrangement of the rotating assembly 2 also reduces the need for the shower head 13 to be directly connected to the connector 1 with a gasket.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
