Description

Technical Field

[0001] The invention relates to the technical field of water dividers, and in particular to a water divider hand wheel. Background Art

[0002] The water distributor hand wheel is widely used as a switch for controlling the water distributor of shower equipment to switch the overhead spray function, shower function or faucet function.

[0003] Chinese patent document CN211924998U discloses a water-dividing hand wheel and a water diverter using the water-dividing hand wheel, the water diverter includes a water-dividing valve, the water-dividing valve includes a valve core housing and a valve stem, the water-dividing hand wheel includes a fixed part fixedly connected to the valve core housing and a rotating part fixedly connected to the valve stem, the fixed part is provided with a plurality of water-discharging marks, the rotating part rotating cover is provided on the fixed part and the rotating part is provided with an observation window corresponding to the water-discharging mark. When the water diverter is in use, the water-dividing hand wheel will only show the water-discharging mark corresponding to the water-discharging function each time the water-discharging hand wheel discharges water, making the water-discharging mark more conspicuous and convenient for immediately identifying the ongoing water-discharging function.

[0004] However, the handwheel of the water distributor adopts a multi-component design. In actual production, multiple components need to be molded and injected separately. At the same time, multiple steps are required for installation. The production efficiency of the handwheel is relatively low, and the development and design cost of the mold is high. In addition, there is no limit block inside the handwheel. When the valve core of the water distributor is closed, the sealing gasket and the valve pipe are excessively squeezed, which causes the sealing gasket to deform, shorten the service life, and reduce the sealing effect. Summary of the invention

[0005] The main purpose of the present invention is to provide a water distributor hand wheel, which can effectively solve the problems of low production efficiency, high production cost and shortened service life.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] A water distributor handwheel comprises a handwheel seat, an external threaded tube is fixed on the upper end of the handwheel seat, a plurality of through grooves are opened on the outer surface of the external threaded tube, a knob is threadedly mounted on the outer surface of the external threaded tube, and a mounting rod is fixed on the top surface of the inner cavity of the knob.

[0008] Preferably, a limiting block is fixed to the upper inner surface of the external threaded tube and the upper inner surface of the knob.

[0009] Preferably, the thread sections of the externally threaded tube and the knob are obtuse triangles, with the long side of the thread of the externally threaded tube located at the upper part and the long side of the thread of the knob located at the lower part.

[0010] Preferably, the through groove penetrates upward.

[0011] Preferably, the hand wheel seat, the external threaded tube and the lower limit block are designed as an integrated unit;

[0012] The knob, the mounting rod and the upper limit block are designed in an integrated manner.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The handwheel of this water distributor adopts the design of external threaded pipe, through groove and knob cooperating with each other, so that the water distributor only needs to press the upper part when installing, which shortens the installation time of the handwheel and improves production efficiency.

[0015] 2. The handwheel of this water distributor adopts the design of limit block, which can prevent the knob from over-rotating, resulting in the knob and the thread of the external threaded pipe not engaging. At the same time, it can also prevent the sealing gasket of the water distributor from being excessively squeezed with the valve pipe when the valve core is closed, thereby causing the sealing gasket to deform, shorten the service life, and reduce the sealing effect, making the water distributor more stable when used.

[0016] 3. The handwheel of this water distributor adopts the design of integrated upper and lower parts, which can reduce the development and design costs of the mold.

[0017] 4. The handwheel of the water distributor adopts a design with a longer pitch of the external threaded pipe and the knob thread, which can shorten the overall length of the handwheel of the water distributor and reduce the installation space. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0025] like Figure 1 - Figure 3 As shown, a water distributor handwheel comprises a handwheel seat 1, the lower part of the inner surface of the handwheel seat 1 is provided with a thread, and the thread is used to be installed on the water distributor, an externally threaded tube 2 is fixed to the upper end of the handwheel seat 1, and a plurality of through grooves 3 are provided on the outer surface of the externally threaded tube 2, a knob 4 is threadedly installed on the outer surface of the externally threaded tube 2, and a mounting rod 5 is fixed to the top surface of the inner cavity of the knob 4. The mounting rod 5 is a prior art and is used to be connected to the valve core of the water distributor. At the same time, due to the design of the threaded connection between the knob 4 and the externally threaded tube 2, the knob 4 can move up and down when it is rotated. At the same time, through the connection between the mounting rod 5 and the valve core, the opening of the water distributor valve is controlled.

[0026] like Figure 4 and Figure 5 As shown, the pitch of the thread of the external threaded pipe 2 and the thread of the knob 4 is relatively long, so that the knob 4 does not need to be rotated continuously during rotation, which can shorten the overall length of the water distributor handwheel and reduce the installation space.

[0027] Limit blocks 6 are fixed to the upper inner surface of the external threaded tube 2 and the upper inner surface of the knob 4. The limit blocks 6 can prevent the knob 4 from over-rotating, thereby causing the threads of the knob 4 and the external threaded tube 2 to not engage. At the same time, they can also prevent the sealing gasket of the valve core of the water distributor from being excessively squeezed against the valve pipe when it is closed, thereby causing the sealing gasket to deform, shorten its service life, and reduce the sealing effect, making the water distributor more stable when in use.

[0028] like Figure 2 - Figure 4 As shown, the thread sections of the externally threaded tube 2 and the knob 4 are obtuse triangles, and the long side of the thread of the externally threaded tube 2 is located at the upper part, and the long side of the thread of the knob 4 is located at the lower part. Due to the mutual cooperation of the two obtuse-angled threads, the device has better self-locking ability when in use than ordinary threads, which can prevent the knob 4 and the externally threaded tube 2 from falling off when the handwheel is in use, thereby increasing the stability of the device when in use.

[0029] like Figure 2As shown, the through groove 3 penetrates upward. Due to the design of multiple through grooves 3, the external threaded tube 2 can be divided into multiple thread blocks, but the multiple thread blocks are adapted to each other (that is, the knob 4 can still be threadedly connected with the multiple thread blocks). When the outer wall of the external threaded tube 2 is squeezed, the multiple thread blocks can be deformed to one side of the central axis of the external threaded tube 2, so that the knob 4 can be directly pressed and installed on the outer surface of the external threaded tube 2 without threaded installation. When installing the knob 4, first place the knob 4 on the through groove 3, and then press the knob 4 downward. When pressing the knob 4, due to the design of multiple through grooves 3, the thread blocks of the external threaded tube 2 can be deformed, so that the knob 4 can be directly sleeved on the outer surface of the external threaded tube 2. Since the outer surface of the external threaded tube 2 and the inner surface of the knob 4 are both provided with threads, the threads will mesh with each other after the knob 4 is sleeved on the outer surface of the external threaded tube 2.

[0030] Furthermore, in order to facilitate the production of the device and reduce the cost of the mold, the handwheel seat 1, the external threaded tube 2 and the lower limit block 6 are designed as an integrated whole, and the knob 4, the mounting rod 5 and the upper limit block 6 are designed as an integrated whole, so that only two molds are used to produce the upper and lower parts of the handwheel during production, and then the upper and lower parts of the handwheel can be installed together, which can reduce the development and design costs of the mold. At the same time, the upper and lower parts are designed, and the outer surface of the external threaded tube 2 is also provided with a plurality of through grooves 3. When installing the upper and lower parts, only the upper part needs to be pressed onto the lower part, which shortens the installation time of the handwheel and improves production efficiency.

[0031] The specific implementation of this embodiment is as follows: since the water divider hand wheel is designed with an upper and lower part, only two sets of molds are needed for production, and multiple sets of molds are not needed for production. Moreover, since there are only two parts, only the two parts need to be assembled together during assembly, which reduces the development and design costs of the mold and also improves the production efficiency of the assembly.

[0032] When assembling the handwheel, due to the design of the through groove 3, it is only necessary to put the upper part on the lower part and then press the upper part to complete the installation. There is no need to install multiple components, which simplifies the steps of water distributor installation and improves the production efficiency of the handwheel.

[0033] When the handwheel is installed on the water distributor, the valve core is first fixedly connected to the installation rod 5, and then the handwheel seat 1 is threadedly installed on the control port of the water distributor. The water flow control of the water distributor can be completed by turning the knob 4.

[0034] It should be noted that the specific installation method, circuit connection method and control method of the hand wheel seat 1 and the knob 4 in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0035] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
