[0035] The utility model embodiment provides a hand wheel assembly can be used for the control operation such as water valve, water faucet. Figure 1 And Figure 2 Hand wheel assembly includes hand wheel 1, tooth pipe piece 3, valve seat 5 and extension rod 6, wherein hand wheel 1 is located above installation platform 100 to facilitate the operation hand wheel 1, tooth pipe piece 3 has axial through hole 31, tooth pipe piece 3 top end is arranged installation platform 100 and is connected hand wheel 1, valve seat 5 is located below installation platform 100 and is connected tooth pipe piece 3 bottom end, valve seat 5 is equipped with valve core 8, extension rod 6 is located in axial through hole 31, extension rod 6 bottom end is connected valve core 8, extension rod 6 top end fixed connection hand wheel 1.

[0036] The hand wheel assembly provided by the utility model is installed on the installation platform 100, the tooth pipe piece 3 can adopt the pipe piece with external threads on the outer wall, and the axial through hole 31 penetrates both ends of the axial direction of the tooth pipe piece 3. The existing conventional hand wheel 1 installation structure does not use tooth pipe piece 3, and the valve core 8 is installed in the internal space of the hand wheel 1 to realize the switching of the water control, and the hand wheel 1 and the valve core 8 are both installed above the installation platform 100, which results in a large installation space above the installation platform 100. The utility model embodiment sets the tooth pipe piece 3 and the extension rod 6, so that the valve seat 5 and the valve core 8 can be installed in the space below the installation platform 100, the valve seat 5 is connected with the bottom end of the tooth pipe piece 3, the hand wheel 1 is connected with the top end of the tooth pipe piece 3, and the valve core 8 is connected to the hand wheel 1 through the extension rod 6 penetrating the tooth pipe piece 3. It can be understood that only the hand wheel 1 is on the table top of the installation platform 100, so the installation height of the hand wheel 1 is low, and the installation structure on the table top of the installation platform 100 is simplified, thereby solving the problems of high installation height and affecting the appearance of the hand wheel assembly on the installation platform 100, facilitating the cleaning and operation of the hand wheel 1, and the design of the appearance structure of the hand wheel 1 is more flexible and is not affected and limited by the valve core 8.

[0037] As shown in Figure 1 And Figure 2 The bottom end of the tooth pipe piece 3 has a connecting section for threadedly connecting the valve seat 5, the outer diameter of the connecting section is smaller than the outer diameter of the body of the tooth pipe piece 3, thereby forming a stepped surface between the connecting section and the body of the tooth pipe piece 3, when the top end of the valve seat 5 is threadedly connected with the connecting section, the top end of the valve seat 5 abuts against the stepped surface for limiting, then it is considered that the valve seat 5 is screwed in place, avoiding overload installation, thereby facilitating the protection of the tooth pipe piece 3 and the valve seat 5.

[0038] In some embodiments, the bottom end of the extension rod 6 is threadedly connected to the valve core 8 and is provided with a radial threaded hole at the threaded connection section, and a top screw 61 is screwed into the radial threaded hole to abut against the valve core 8.

[0039] As shown in Figure 2 and Figure 3 , the top end of the valve core 8 is provided with external threads, and the bottom end of the extension rod 6 is provided with internal threads. After the bottom end of the extension rod 6 is threadedly connected to the top end of the valve core 8, since the extension rod 6 and the valve core 8 have synchronous movement during operation, in order to ensure the connection strength and movement consistency between the extension rod 6 and the valve core 8, in this embodiment, a top screw 61 is arranged at the threaded connection between the extension rod 6 and the valve core 8, and the top screw 61 is threadedly connected to the extension rod 6. By adjusting the screwing depth of the top screw 61, the top screw 61 can abut against the threaded gap of the external threads of the valve core 8. The top screw 61 can prevent loosening between the valve core 8 and the extension rod 6, and is beneficial to improve the connection strength between the valve core 8 and the extension rod 6.

[0040] In some embodiments, the handwheel assembly further comprises an electronic display screen 2 and a control box 7, and the electronic display screen 2 is arranged on the handwheel 1; and the control box 7 is electrically connected with the electronic display screen 2.

[0041] As shown in Figure 1 and Figure 2 , the electronic display screen 2 is preferably arranged on the top surface of the handwheel 1, which is convenient for observation and cleaning. The electronic display screen 2 is used to display water temperature and TDS value and other parameters, which meets different user needs. The control box 7 and the electronic display screen 2 are connected through an electric wire, which has the functions of power supply and signal transmission. The control box 7 can charge the electronic display screen 2 through the electric wire, and display the water temperature parameter and the TDS value parameter on the electronic display screen 2.

[0042] In some embodiments, the side wall of the tooth pipe 3 is provided with a radial through hole 32 communicating with the axial through hole 31, the control box 7 is located below the mounting table 100, and the electric wire of the control box 7 passes through the radial through hole 32 and is connected to the electronic display screen 2 along the axial through hole 31.

[0043] As shown in Figure 2 and Figure 3As shown, the radial through hole 32 communicates the inner and outer sides of the side wall of the tooth tube 3, and the bottom end of the radial through hole 32 is higher than the stepped surface of the tooth tube 3 connected to the valve seat 5. By arranging the radial through hole 32 on the side wall of the tooth tube 3, the control box 7 can be arranged below the mounting table 100, and the wires of the control box 7 can pass through the radial through hole 32 and be connected to the electronic display screen 2 on the hand wheel 1 through the axial through hole 31 to realize the display function of the hand wheel 1. After installation, there is no obvious wire on the upper and lower parts of the mounting table 100. The wires are connected to the electronic display screen 2 inside the hand wheel 1 and are guided downward to the radial through hole 32 through the axial through hole 31 and then are led out to the control box 7. It can be understood that the tooth tube 3 solves the wire routing problem, and the wires are located in the tooth tube 3 together with the extension rod 6, which realizes the isolation of the valve core 8 and the wires and improves the safety of the wires. It can be understood that the outer diameter of the extension rod 6 is smaller than the hole diameter of the axial through hole 31, so that there is sufficient gap between the extension rod 6 and the axial through hole 31 for wire routing and arrangement. Further, as shown in Figure 3 The connection position of the valve core 8 and the extension rod 6 is opposite to the radial through hole 32 on the tooth tube 3, which facilitates the rotation of the top wire 61 through the radial through hole 32 and facilitates maintenance and maintenance. The end of the top wire 61 adopts an internal hexagonal structure to facilitate the rotation operation through a tool.

[0044] In some embodiments, two radial through holes 32 are arranged, and the two radial through holes 32 are arranged in the circumferential direction of the tooth tube 3, and the wires are arranged in any one of the radial through holes 32.

[0045] As shown in Figure 3 In this embodiment, the two radial through holes 32 are arranged symmetrically at 180° on the side wall of the tooth tube 3. During installation, the tooth tube 3 and the hand wheel 1 are threadedly connected, and the locking member 4 and the tooth tube 3 are also threadedly connected. The arrangement of the two radial through holes 32 facilitates the leading out of the wires at appropriate positions, avoids problems such as wire winding or position interference, and facilitates installation. Specifically, the radial through hole 32 has an extension height in the axial direction of the tooth tube 3, that is, the radial through hole 32 is a long slot hole, which facilitates the operation of wire routing. In some embodiments, when the radial through hole 32 has a relatively large width extending around the axis of the tooth tube 3, one radial through hole 32 can also be used. However, considering the structural strength of the tooth tube 3, the width of the radial through hole 32 cannot be too large.

[0046] In some embodiments, the hand wheel assembly further comprises a locking member 4, the locking member 4 is sleeved on the tooth tube 3 and is threadedly connected with the tooth tube 3, and the mounting table 100 is clamped between the hand wheel 1 and the locking member 4.

[0047] As shown in Figure 3As shown, taking the locking nut as an example, adjusting the threaded connection position of the locking member 4 on the tooth pipe member 3 can clamp and install the mounting table 100 between the locking member 4 and the hand wheel 1, so that the hand wheel 1 can be in close contact with the table surface of the mounting table 100, thereby improving the installation stability of the hand wheel 1 and the tooth pipe member 3 on the mounting table 100 and avoiding loosening. In some embodiments, when the locking member 4 is installed, the locking member 4 is located at a high position relative to the radial through hole 32, and the locking position of the locking member 4 has a certain interval distance from the radial through hole 32, so as to avoid damaging the electric wire during the rotation of the locking member 4, and to ensure that the locking member 4 and the tooth pipe member 3 have sufficient threaded connection surface to ensure the connection strength.

[0048] In some embodiments, the locking member 4 is provided with an axial threaded hole 41, and a bolt 42 is threadedly connected in the axial threaded hole 41. The bolt 42 abuts against the lower surface of the mounting table 100.

[0049] As shown in Figure 2 and Figure 3 , the bolt 42 is threadedly connected to the circumferential position of the lower end surface of the locking member 4. Therefore, the bolt 42 can be pre-installed on the locking member 4 before the hand wheel assembly is installed, so as to avoid the loss of parts. After the locking member 4 is tightened and installed in place, the rotation depth of the bolt 42 is increased, so that the bolt 42 abuts against the lower surface of the mounting table 100, thereby facilitating the increase of the connection strength between the locking member 4 and the tooth pipe member 3 and avoiding loosening. Preferably, the locking member 4 is provided with two bolts 42, and the two bolts 42 are symmetrically arranged to provide symmetrical abutting force. When the hand wheel 1 loosens after long-time use, adjusting the pre-tightening force of the two bolts 42 can further tighten the hand wheel 1.

[0050] In some embodiments, the hand wheel assembly further comprises a circlip 9 and a gasket 10. The circlip 9 and the gasket 10 are sleeved on the tooth pipe member 3 and clamped between the locking member 4 and the lower surface of the mounting table 100, and the bolt 42 abuts against the circlip 9.

[0051] As shown in Figure 3 and Figure 4 , when the hand wheel assembly is installed, the circlip 9 and the gasket 10 are sequentially sleeved on the tooth pipe member 3 and clamped between the locking member 4 and the lower surface of the mounting table 100, for sealing the mounting hole on the mounting table 100 for the tooth pipe member 3 to pass through, and being capable of elastically adjusting the tightening degree of the locking member 4 and the bolt 42. The gasket 10 is made of elastic rubber or the like, and provides good sealing and elastic abutting force. The gasket 10 is in contact with the lower surface of the mounting table 100, for protecting the lower surface of the mounting table 100. The circlip 9 is made of metal, for supporting the gasket 10 and isolating the locking member 4. The circlip 9 can be clamped on the external thread of the tooth pipe member 3 to further improve the connection strength between the tooth pipe member 3 and the locking member 4, and has a loosening effect.

[0052] In some embodiments, the clamping spring 9 has an opening 91, and the locking piece 4 has an avoiding gap 43, the opening 91 and the avoiding gap 43 are arranged in a circumferential direction.

[0053] For example Figure 4 And Figure 5 The locking piece 4 has an avoiding gap 43, that is, the cross section of the locking piece 4 is in the form of an open ring structure, when the locking piece 4 is sleeved on the tooth pipe 3 for installation, the avoiding gap 43 can avoid the electric wire at the radial through hole 32 for axial installation, which is beneficial to quick installation; improve the adaptability of the locking piece 4, avoid jamming. Of course, during installation, the locking piece 4, the gasket 10 and the clamping spring 9 can be installed on the tooth pipe 3 and located above the radial through hole 32, and then the wire and the hand wheel 1 are installed. The opening 91 of the clamping spring 9 is arranged in a circumferential direction with the avoiding gap 43, and the two bolts 42 can abut against the lower surface of the clamping spring 9 when increasing the screwing depth, so that the clamping spring 9 and the gasket 10 are clamped between the bolt 42 and the lower surface of the mounting table 100. The bolt 42 is in abutting contact with the clamping spring 9, which avoids damaging the lower surface of the mounting table 100, and the bolt 42 can further improve the locking effect of the locking piece 4.

[0054] In some embodiments, the hand wheel 1 comprises a fixed part and a rotating part, the rotating part is rotatably installed on the fixed part, the fixed part is in threaded connection with the tooth pipe 3, and the rotating part is fixedly connected with the top end of the extension rod 6.

[0055] The rotating part can drive the extension rod 6 and the valve core 8 to rotate to realize water outlet control, the bottom end of the fixed part after installation is in abutting contact with the upper surface of the mounting table 100, and thus the mounting table 100 has only the structure of the hand wheel 1 on the table surface, the installation of the hand wheel 1 is not affected by the valve core 8, the structure is simple and beautiful, the height is small, and cleaning is convenient. The top end of the hand wheel 1 is provided with the electronic display screen 2, which is beautiful and convenient for observing the display content. The connection between the fixed part and the rotating part is prior art, which will not be described herein.

[0056] The utility model embodiment further provides a water valve, including the hand wheel subassembly that the utility model provides.
