Description

Technical Field

[0001] This utility model relates to the field of bathroom parts, specifically a novel single-handle handle. Background Technology

[0002] In existing technologies, single-handle valves are widely used for operating valves and switching devices in the bathroom industry. To ensure the handle can effectively transmit operating torque and achieve precise control, the valve stem mounting structure on the handle is crucial. However, existing connection methods, especially welding, have the following main problems:

[0003] Limitations of welding connection methods:

[0004] Welded joints are prone to breakage: Currently, valve stems on handles are typically fixed using welding methods, such as ultrasonic welding, high-frequency welding, and infrared welding. While these methods provide a certain degree of robust connection, the welded joints are susceptible to fatigue fracture during prolonged use, especially under frequent operation or high stress.

[0005] Insufficient connection strength: Welding points are usually areas of concentrated mechanical stress. Under repeated loading and unloading, they are more prone to cracking and eventually breakage, resulting in insufficient connection strength.

[0006] Deviation risk:

[0007] If the weld point breaks, the valve stem may deviate, which not only affects the normal operation of the handle but may also cause the entire control system to fail, posing a serious safety hazard.

[0008] Environmental factors:

[0009] External environmental factors, such as temperature changes, humidity, and corrosion, can accelerate the aging and failure of welded joints, further reducing the reliability of the connection and shortening the service life of the equipment. Summary of the Invention

[0010] (a) Technical problems to be solved

[0011] To address the shortcomings of existing technologies, this utility model provides a novel single-handle grip.

[0012] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A novel single-handle grip of this utility model includes a handle base, a counterweight, a rear pressure cover, and a retaining ring. The handle base has an internal cavity, and a valve stem is provided in the cavity. The valve stem has a valve hole. The counterweight, the rear pressure cover, and the retaining ring are all sleeved on the valve stem. The counterweight is located at the bottom of the cavity, the rear pressure cover covers the counterweight, and the retaining ring is located at the top of the rear pressure cover. The inner wall of the cavity has symmetrical buckles, and the outer wall of the rear pressure cover has symmetrical buckle grooves. The buckle grooves are L-shaped and are adapted to the buckles.

[0013] Preferably, the rear pressure cover has a protrusion, the protrusion has a screw groove, the protrusion has a through hole, the through hole passes through the screw groove, and a screw is inserted into the screw groove. The handle seat has a fixing hole, the valve stem has a connecting hole, the fixing hole and the connecting hole are adapted to the through hole, and a fixing bolt is installed in the fixing hole. The fixing bolt is adapted to the screw and the connecting hole.

[0014] More preferably, the retaining ring has an elastic opening, the retaining ring is made of elastic plastic material, and the retaining ring fits against the valve stem.

[0015] Preferably, the retaining ring is made of thermoplastic polyurethane or thermoplastic elastomer.

[0016] More preferably, the end of the buckle groove is provided with an elastic buckle, and the buckle and the elastic buckle are made of elastic plastic material, and the buckle and the elastic buckle are elastically compressed.

[0017] Preferably, the rear pressure cover has symmetrical protrusions on both sides, and the protrusions are used as force points for disassembling and assembling the rear pressure cover.

[0018] (III) Beneficial Effects Compared with the prior art, the present invention provides a novel single-handle handle, which has the following beneficial effects:

[0019] Highly efficient and reliable connection and operation:

[0020] In existing technologies, valve stems on handles are typically fixed by welding, such as ultrasonic welding, high-frequency welding, and infrared welding. Although these methods provide a robust connection, the weld joints are prone to fatigue fracture during prolonged use or frequent operation.

[0021] Improvement measures: The valve stem of this utility model adopts a non-welded connection method, and the valve stem and handle seat are integrated into one structure, which avoids the problem of fatigue fracture at the welding point.

[0022] The handle seat has an internal cavity to accommodate the valve stem, counterweight, rear pressure cap, and retaining ring, providing a compact and flexible spatial layout;

[0023] The counterweight is located at the bottom of the cavity and is fitted onto the valve stem to provide balance to the handle seat, ensuring that the handle seat remains stable during operation and improving operating accuracy;

[0024] The outer wall of the rear pressure cover is symmetrically provided with L-shaped buckle grooves. These buckle grooves are adapted to the buckles on the inner wall of the handle seat. The rear pressure cover can be quickly installed and removed by rotating it, which simplifies the installation process. The installation of the rear pressure cover plays a limiting role for the counterweight.

[0025] The screws in the screw slots are matched with the fixing holes on the handle seat and the connecting holes on the valve stem to ensure the firmness of the rear cover installation, while also facilitating maintenance and replacement.

[0026] The retaining ring has an elastic opening. The retaining ring contacts the valve stem through elastic compression, providing additional friction and further preventing the rear pressure cap from loosening or shifting. Attached Figure Description
