Description

Technical Field

[0001] This utility model relates to the field of shower head technology, specifically to a handle connection part of a lever shower head. Background Technology

[0002] A lever showerhead is a shower device that allows you to adjust the water flow mode using a side lever, commonly found in mechanical switching valve designs. Its core function is to switch water flow modes, such as massage or single-stream, through a physical lever. Some models also support thermostatic control or pressurization design.

[0003] like Figure 1 As shown, a conventional lever shower head includes a shower head body 1', a positioning member 2' located at the lower end of the shower head body 1', a rotating lever 3' located between the lower end of the shower head body 1' and the positioning member 2', a connecting bolt 4' located between the positioning member 2' and the shower head body 1', and a water inlet end 5' located at the lower end of the positioning member 2'. The rotating lever 3' has a rotating opening in its middle, which is clearance-fitted with a boss at the bottom of the shower head body 1'. The lower end of the positioning member 2' and the upper end of the water inlet end 5' are connected by threads, a boss, and a groove, or by a sealing ring. The structure can also be seen in Chinese Patent Application No. 2025219101474, which describes a shower head with an adjustable water flow mode.

[0004] Although existing lever-type showerhead structures allow for changes in water flow by rotating the lever, when both hands are holding the inlet end and rotating the lever for control, the rotation of the lever can easily cause the positioning component to rotate at the upper end of the inlet end. This can lead to separation between the lower end of the positioning component and the upper end of the inlet end, resulting in unstable connection at the showerhead handle. This can affect the normal use of the entire showerhead and may even cause leaks. Furthermore, during long-term use, this connection method is prone to wear due to frequent relative rotation, reducing the lifespan of the showerhead. Utility Model Content

[0005] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a handle connection part for a lever shower head.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a handle connection part of a lever shower head, including a water inlet end and a positioning member disposed at the upper end of the water inlet end. The positioning member is rotatably disposed at the upper end of the water inlet end. A positioning slot is provided at the upper end of the water inlet end. A positioning plate is fixedly disposed at the lower end of the positioning member for inserting into the positioning slot after the positioning member is installed at the upper end of the water inlet end. A fixing member is provided between the positioning plate and the water inlet end for fixing the positioning plate in the positioning slot after the positioning plate is inserted into the positioning slot.

[0007] A further improvement is that a rotating lever is rotatably provided at the upper end of the positioning component.

[0008] A further improvement is that: two Z-shaped grooves are provided on the upper circumference of the water inlet end, and a square slider is provided on the lower circumference of the positioning member for clearance matching with the Z-grooves; the positioning groove is an arc-shaped groove, and the positioning plate is an arc-shaped plate; the arc length of the positioning groove is greater than the arc length of the positioning plate.

[0009] Further benefits: The Z-shaped groove and square slider facilitate the disassembly and reassembly of the water inlet end and the positioning component, allowing for easy installation and disassembly compared to using threads directly.

[0010] A further improvement is that the fixing component includes a threaded opening and a connecting hole respectively opened on the water inlet end and connected to the positioning slot, a corresponding insertion hole through the positioning plate, and a positioning screw disposed between the positioning plate and the end for fixing the positioning plate in the positioning slot when the positioning plate is inserted into the positioning slot and the corresponding insertion hole corresponds to the position of the threaded opening and the connecting hole respectively. The positioning screw is threadedly connected to the threaded opening and has a clearance fit with the connecting hole.

[0011] Further effects: After the positioning component is installed on the upper end of the water inlet, the positioning plate is inserted into the positioning slot. If the corresponding insertion holes correspond to the positions of the threaded opening and the connecting insertion hole, the positioning screw is inserted from the position of the connecting insertion hole, so that the positioning screw passes through the corresponding insertion hole and is threadedly connected to the threaded opening hole, thereby restricting the lifting and lowering of the positioning plate in the positioning slot and achieving the fixing effect between the positioning plate and the water inlet.

[0012] A further improvement is that a driving part is provided at the end of the positioning screw.

[0013] A further improvement is that the driving part is an internal driving hole or an external driving plate. After adopting the above technical solution, the beneficial effects of this utility model are as follows: After the positioning component is installed at the upper end of the water inlet, the positioning plate is inserted into the positioning slot, and then the positioning plate is fixed in the positioning slot by the fixing component. This restricts the longitudinal movement and circumferential rotation of the positioning component on the water inlet. When both hands hold the water inlet and the rotating lever for control, the positioning component can be firmly fixed on the water inlet, preventing separation between the lower end of the positioning component and the upper end of the water inlet. This reduces the likelihood of unstable connection at the shower head handle connection and prevents wear due to frequent relative rotation during long-term use, thus extending the shower head's lifespan.

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0018] See Figures 2 to 8 As shown, the technical solution adopted in this specific embodiment is: a handle connection part of a lever shower head, including a water inlet end 1 and a positioning member 2 disposed at the upper end of the water inlet end 1. The positioning member 2 is rotatably disposed at the upper end of the water inlet end 1. A positioning slot 3 is formed at the upper end of the water inlet end 1. A positioning plate 4 is fixedly disposed at the lower end of the positioning member 2 for inserting into the positioning slot 3 after the positioning member 2 is installed at the upper end of the water inlet end 1. A fixing member is provided between the positioning plate 4 and the water inlet end 1 for fixing the positioning plate 4 in the positioning slot 3 after the positioning plate 4 is inserted into the positioning slot 3. The lower end of the water inlet end 1 is provided with a threaded surface for connecting to an external water inlet end. The positioning plate 4 and the positioning member 2 are integrally formed. Figure 8 As shown, a sealing groove is provided at the upper end of the water inlet end 1, and a sealing ring is placed in the sealing groove to seal the gap between the water inlet end 1 and the positioning member 2 when the positioning member 2 is installed on the water inlet end 1.

[0019] The upper end of the positioning component 2 is rotatably equipped with a rotating lever 5. The upper surface of the positioning component 2 is stepped, and the lower end of the rotating lever 5 is fitted with a stepped groove on the upper surface of the positioning component 2. This groove enables a rotational engagement between the rotating lever 5 and the upper end of the positioning component 2. As described in the background art, the positioning component 2 is threadedly connected to the shower body via bolts, and the rotating lever 5 is pressed against the shower body by the positioning component 2, thereby restricting the longitudinal direction of the rotating lever 5. A through hole is provided in the middle of the rotating lever 5, which is clearance-fitted with a convex shaft at the bottom of the shower body to achieve a rotational connection. For the specific structure of this part, please refer to the content of application number: 2025219101474.

[0020] The upper circumference of the water inlet end 1 has two Z-shaped grooves 6, and the lower circumference of the positioning member 2 has a square slider 7 for clearance fitting with the Z-shaped grooves. The positioning slot 3 is an arc-shaped slot, and the positioning plate 4 is an arc-shaped plate. The arc length of the positioning slot 3 is greater than the arc length of the positioning plate 4. The specific structure of the Z-shaped grooves 6 and the square slider 7 is as follows: Figure 6 and Figure 8 and Figure 2As shown, the specific structure is as described in the prior art Chinese patent number CN202421705331.0 regarding the structure and description of the sliding protrusion and L-shaped slide. When setting the Z-shaped slide groove 6 and the square slider 7, the arc length of the positioning slot 3 should be greater than the arc length of the positioning plate 4, so that when the square slider 7 enters from the Z-shaped slide groove 6, the positioning plate 4 can also be inserted into the positioning slot 3 at the same time. After the positioning member 2 is rotated to lock the Z-shaped slide groove 6 and the square slider 7, the positioning plate 4 can also change position within the positioning slot 3, thus not affecting the cooperation between the Z-shaped slide groove 6 and the square slider 7. If the Z-shaped slide groove 6 and the square slider 7 are not set, the positioning slot 3 and the positioning plate 4 can be directly set as a square plate or an arc plate. In this case, the opening width or arc length of the positioning slot 3 does not need to be greater than the opening width or arc of the positioning plate 4, and it can be completed simply by going straight up and down.

[0021] The fixing component includes a threaded opening 8 and a connecting insertion hole 9 respectively opened on the water inlet end 1 and connected to the positioning slot 3, a corresponding insertion hole 12 through the positioning plate 4, and a positioning screw 10 disposed between the positioning plate 4 and the end for fixing the positioning plate 4 in the positioning slot 3 when the positioning plate 4 is inserted into the positioning slot 3 and the corresponding insertion hole 12 corresponds to the positions of the threaded opening 8 and the connecting insertion hole 9 respectively. The positioning screw 10 is threadedly connected to the threaded opening 8 and the positioning screw 10 is clearance-fitted with the connecting insertion hole 9.

[0022] When setting the Z-shaped slide groove 6 and the square slider 7, the positions of the threaded opening 8 and the connecting insertion hole 9 are such that, after the positioning block rotates, the corresponding insertion hole 12 aligns with the corresponding positions of the threaded opening 8 and the connecting insertion hole 9. The diameters of the corresponding insertion hole 12 and the connecting insertion hole 9 are larger than the diameter of the positioning screw 10.

[0023] The end of the positioning screw 10 is provided with a driving part 11.

[0024] The driving part 11 can be an internal driving hole or an external driving plate. The internal driving hole can be an internal hexagonal hole, a cross-shaped internal hole, or a slotted internal hole. The external driving plate can be an external hexagonal plate or other polygonal plate. The driving part 11 facilitates the driving of the positioning screw 10 by tools. In particular, when the internal driving hole is set, the length of the positioning screw 10 can be completely concealed in the threaded opening 8, the connecting insertion hole 9, and the corresponding insertion hole 12 after the threaded connection is made.

[0025] The working principle of this utility model is as follows: After the positioning component 2 is installed on the upper end of the water inlet end 1, the positioning plate 4 is inserted into the positioning slot 3, so that the corresponding insertion hole 12 corresponds to the position of the threaded hole 8 and the connecting insertion hole 9 respectively. Then, the positioning screw 10 is inserted from the position of the connecting insertion hole 9, so that the positioning screw 10 passes through the corresponding insertion hole 12 and is threadedly connected to the threaded hole 8, thereby restricting the lifting and lowering of the positioning plate 4 in the positioning slot 3, realizing the fixing effect between the positioning plate 4 and the water inlet end 1. It can restrict the longitudinal movement and circumferential rotation of the positioning component 2 on the water inlet end 1. When the water inlet end 1 and the rotating lever 5 are held by both hands respectively for control, the positioning component 2 can be firmly fixed on the water inlet end 1, and the lower end of the positioning component 2 will not separate from the upper end of the water inlet end 1. It is not easy to cause unstable connection of the shower handle connection part. During long-term use, it will not wear due to frequent relative rotation, thus reducing the service life of the shower.
