Description

Technical Field

[0001] This utility model relates to the field of hardware and sanitary ware technology, specifically to a rocker arm assembly for sanitary ware products. Background Technology

[0002] Currently, most bathroom products on the market, such as faucets and towel racks, have a fixed structure. However, in order to increase the convenience of use, swing-arm bathroom products have also emerged. By rotating the swing arm, the range of use can be greatly increased.

[0003] like Figure 1 and 2 The image shows a rocker arm assembly for a bathroom product, including a rotating rocker arm 1 and rotating connectors 2 adapted to both ends of the rotating rocker arm 1. Both ends of the rotating rocker arm 1 are provided with integrally integrated rocker arm connecting portions 11. Connecting grooves 111 are formed on the rocker arm connecting portions 11. The rotating rocker arm 1 has a hollow structure, and the connecting grooves 111 at both ends are interconnected. The lower end of the rocker arm connecting portion 11 and the upper end of the rotating connector 2 are respectively provided with matching locking protrusions 112 and locking grooves 21. Upper connecting teeth 1121 and lower connecting teeth 211 are respectively provided on the locking protrusion 112 and locking groove 21, which are interlocked. A locking sealing ring 113 adapted to the inner wall of the locking groove 21 is fitted on the locking protrusion 112. The rotating connector 2 is provided with a connecting head groove 22 adapted to the connecting groove 111. A through-hole through-connecting groove 111 passes through the connecting head groove 22. The connecting rod 3 has an integrally formed limiting plate 31 at its lower part. The limiting plate 31 abuts against the lower end of the rotating connector 2. The upper end of the limiting plate 31 is also provided with an integrally formed sealing boss 32. The upper part of the connecting rod 3 is provided with an integrally formed sealing ring 33. The sealing ring 33 and the sealing boss 32 are respectively fitted with an upper sealing ring 6 and a lower sealing ring 7 that are adapted to the inner walls of the connecting part groove 111 and the connecting head groove 22. A flow cavity is formed between the sealing ring 33 and the sealing boss 32 that communicates with the middle of the rotating rocker arm 1. The upper end of the connecting rod 3 is also fitted with a rotating washer 4 and a locking nut 5 located outside the connecting part groove 111. The cross-section of the upper end of the connecting rod 3 is set with a straight groove shape. The rotating connector 2 has a connection port 23 on one side that communicates with the flow cavity. The connection port 23 is used to connect any one of the following: the faucet body, the faucet outlet, the towel rack body, etc.

[0004] When it is necessary to adjust the angle of the connection port 23, the user needs to first loosen the locking nut 5 so that the connecting rod 3 can move downward relative to the rocker arm connection part 11. This causes the lower connecting tooth 211 on the rotating connector 2 and the upper connecting tooth 1121 on the rotating connection part to no longer be engaged and separate. The rotating connector 2 can then rotate freely to adjust the angle of the connection port 23. After adjusting to the appropriate angle, tighten the locking nut 5 again so that the limiting plate 31 at the lower end of the connecting rod 3 pushes the rotating connector 2 toward the rocker arm connection part 11 until the lower connecting tooth 211 and the upper connecting tooth 1121 are engaged again and the rotating connector 2 can no longer rotate.

[0005] Although the above structure can adjust the angle of the connection port 23, the structure is complex and requires repeated tightening of the locking nut 5 during each adjustment, which is time-consuming and laborious. In the loose state, the locking nut 5 is also easy to fall out of the connecting rod 3 and be lost, causing inconvenience in use. Utility Model Content

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] This embodiment discloses a rocker arm assembly for bathroom products, such as... Figures 1 to 5 As shown, it includes a rotating rocker arm 1 and rotating connectors 2 that are adapted to both ends of the rotating rocker arm 1. Both ends of the rotating rocker arm 1 are provided with rocker arm connecting parts 11 that are adapted to the rotating connectors 2. The rocker arm connecting parts 11 and the rotating rocker arm 1 are integrally formed. The rocker arm connecting parts 11 are provided with connecting part grooves 111 that are adapted to the rotating connectors 2. A connecting rod 3 that slides up and down is passed through the connecting part grooves 111. The upper part of the connecting rod 3 passes through the connecting part grooves 111 and is detachably connected to the rotating connectors 2. The rotating connectors 2 move with the upper end of the connecting rod 3. A connecting port 23 that is adapted to the rotating connector 2 is provided on one side. The connecting port 23 is used to connect to the main body of the towel rack or other structures that do not require water flow.

[0035] The rotating connector 2 has a fixing groove 24 that matches the upper end of the connecting rod 3. The inner wall of the fixing groove 24 and the upper part of the connecting rod 3 are respectively provided with matching internal thread 241 and external thread 34. The lower end of the connecting rod 3 is provided with a screwing groove 35 that matches the external thread 34. The cross-section of the screwing groove 35 is set to any one of the following: flat head, cross head, or internal hexagon. The screwing groove 35 is screwed by external tools such as flat head screwdriver, cross head screwdriver, or hexagon head, so that the connecting rod 3 and the rotating connector 2 can be detachably connected.

[0036] A first gear portion 114 and a second gear portion 36 are respectively provided between the connecting groove 111 and the connecting rod 3. The first gear portion 114 and the first gear portion 36 are respectively provided with a first connecting tooth 1141 and a second connecting tooth 361 evenly distributed in the circumferential direction. The first connecting tooth 1141 and the second connecting tooth 361 are respectively provided with a first guide chamfer 1142 and a second guide chamfer 362. By providing the first guide chamfer 1142 and the second guide chamfer 362, it is easy for the first connecting tooth 1141 and the second connecting tooth 361 to quickly mesh.

[0037] A matching guide ring 25 and guide groove 115 are respectively provided between the rotating connector 2 and the rocker arm connecting part 11. The guide ring 25 and guide groove 115 cooperate with each other to shield and prevent foreign objects from entering the connection gap between the outer connecting teeth and the inner connecting teeth when they are separated, thus ensuring the reliability of the operation.

[0038] The lower ends of the connecting rod 3 and the rocker arm connecting part 11 are respectively provided with a matching limiting plate 31 and a limiting groove 116. The limiting plate 31 and the limiting groove 116 cooperate with each other to limit the connection and prevent the connecting rod 3 from coming out of the connecting part groove 111. A lower compression spring 8 is also sandwiched between the limiting plate 31 and the limiting groove 116. The lower compression spring 8 is sleeved on the lower part of the connecting rod 3 and plays a reset role.

[0039] The usage process is as follows: When the user adjusts the angle of the connection port 23, the rotating connector 2 is pulled upwards to one side of the rocker arm connection 11 to overcome the pressure of the lower compression spring 8, causing the rotating connector 2 to drive the connecting rod 3 upwards. This causes the first gear 114 and the second gear 36 on the rocker arm connection 11 and the connecting rod 3 to separate from each other. Then, the rotating connector 2 is rotated to adjust the angle of the connection port 23. Next, the rotating connector 2 is released, so that the rotating connector 2 is reset under the action of the lower compression spring 8. The first connecting tooth 1141 and the second connecting tooth 361 quickly mesh and connect under the action of the first guide chamfer 1142 and the second guide chamfer 362. The rotating connector 2 can no longer rotate, thereby achieving a quick adjustment of the angle of the connection port 23.

[0040] Example 2: The difference between this example and Example 1 is that, as shown in Example 2... Figures 6 to 8 As shown, a matching connection port 23 is provided on one side of the rotating connector 2. The rotating connector 2 is also provided with a connector groove 22 that communicates with the connection port 23 and the fixing groove 24. The connection port 23 is used to connect with water-conducting bathroom products such as the faucet body or faucet outlet, but it can also be connected with water-non-conducting bathroom products such as the towel rack body.

[0041] The outer side of the connecting rod 3 is provided with an upper limit protrusion ring 37 and a lower limit protrusion ring 38. The upper limit protrusion ring 37 and the lower limit protrusion ring 38 are respectively embedded with an upper sealing ring 6 and a lower sealing ring 7 that abut against the inner wall of the groove 111 of the connecting part. The cross-section of the upper sealing ring 6 and the lower sealing ring 7 is V-shaped and the openings face each other. The upper limit protrusion ring 37 and the lower limit protrusion ring 38 are both provided with sealing ring grooves 371. The upper sealing ring 6 and the lower sealing ring 7 ensure the sealing performance when water flows through the connecting rod 3.

[0042] A flow cavity is formed between the upper sealing ring 6 and the lower sealing ring 7 to match the middle of the rotating rocker arm 1. The rocker arm 1 has a rocker arm cavity 12 that communicates with the flow cavity. The connecting rod 3 has an upward-facing connecting rod groove 39. The inner wall of the connecting rod groove 39 has a connecting rod through hole 391 that communicates with the flow cavity. The connecting rod through hole 391 is located between the upper sealing ring 6 and the lower sealing ring 7. The water flows through the connection port 23, the connecting rod groove 39, the connecting rod through hole 391, the flow cavity, the rocker arm cavity 12, the flow cavity on the other side, the connecting rod through hole 391, the connecting rod groove 39, and the connection port 23 in sequence.

[0043] The lower end of the external threaded part 34 is provided with a connecting sealing ring 341 that is adapted to the lower end of the internal threaded part 241. The connecting sealing ring 341 is sleeved on the upper part of the connecting rod 3. The lower ends of the internal threaded part 241 and the external threaded part 34 are respectively provided with a first connecting sealing groove and a second connecting sealing groove that are adapted to the connecting sealing ring 341. The connecting sealing ring 341 improves the sealing performance at the connection between the connecting rod 3 and the rotating connector 2.

[0044] Example 3, based on Example 2, such as... Figure 9 As shown, the lower end face of the first gear part 114 forms an upper limit surface. An upper compression spring 9 is sandwiched between the upper limit surface and the upper limit protrusion ring 37. The upper compression spring 9 is sleeved on the connecting rod 3. The upper compression spring 9 facilitates the quick reset of the connecting rod 3 after it is pulled, and at the same time avoids the lower compression spring 8 from failing after long-term use and affecting the reset of the connecting rod 3, thereby improving the overall reliability.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
