Abstract
Description
Technical Field
[0001] This utility model relates to the field of water distributor technology, and in particular to a water distributor handwheel. Background Technology
[0002] The manifold handwheel is widely used as a switch to control the switching of the shower manifold between overhead spray, shower head, or faucet functions.
[0003] Chinese patent document CN211924998U discloses a water-distributing handwheel and a water distributor using the same handwheel. The water distributor includes a water-distributing valve, which comprises a valve core housing and a valve stem. The water-distributing handwheel includes a fixing component fixedly connected to the valve core housing and a rotating component fixedly connected to the valve stem. The fixing component has several water outlet indicators, and the rotating component has a rotating cover on the fixing component with an observation window corresponding to each water outlet indicator. During use, the water distributor only displays the water outlet indicator corresponding to each water outlet function, making the water outlet indicators more conspicuous and facilitating immediate identification of the current water outlet function.
[0004] However, the handwheel of this water distributor adopts a multi-component design, which requires multiple components to be molded and injection molded separately during actual production. At the same time, multiple steps are required during installation, resulting in relatively low production efficiency of the handwheel and high mold development and design costs. In addition, there is no limit block inside the handwheel, and the valve core of the water distributor is excessively squeezed between the sealing gasket and the valve pipe when closed, which leads to deformation of the sealing gasket, shortened service life, and reduced sealing effect. Utility Model Content
[0005] The main purpose of this utility model is to provide a water distributor handwheel that can effectively solve the problems of low production efficiency, high production cost and shortened service life.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A water distributor handwheel includes a handwheel base, an externally threaded tube fixed to the upper end of the handwheel base, a plurality of through grooves being formed on the outer surface of the externally threaded tube, a knob being threadedly mounted on the outer surface of the externally threaded tube, and an installation rod being fixed to the top surface of the inner cavity of the knob.
[0008] Preferably, a limit block is fixed to the upper part of the inner surface of the external threaded tube and the upper part of the inner surface of the knob.
[0009] Preferably, the threaded cross-sections of the external threaded pipe and the knob are obtuse triangles, with the long side of the external threaded pipe located at the top and the long side of the knob thread located at the bottom.
[0010] Preferably, the through groove extends upwards.
[0011] Preferably, the handwheel seat, the external threaded tube, and the lower limiting block are designed as a single unit;
[0012] The knob, mounting rod, and upper limit block are designed as a single unit.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. The handwheel of this water distributor adopts a design that combines an external threaded pipe, a through groove, and a knob, so that the water distributor only needs to be pressed on the upper part during installation, which shortens the installation time of the handwheel and improves production efficiency.
[0015] 2. The handwheel of this manifold adopts a limit block design, which can prevent the knob from being rotated too much, thus preventing the knob from not engaging with the thread of the external threaded pipe. It can also prevent the sealing gasket from being squeezed too much with the valve pipe when the valve core of the manifold is closed, which would cause the sealing gasket to deform, shorten its service life, and reduce the sealing effect, making the manifold more stable when in use.
[0016] 3. The handwheel of this water distributor adopts a design in which both the upper and lower parts are integrally formed, which can reduce the development and design costs of molds.
[0017] 4. The handwheel of this manifold adopts a design with a longer pitch of external thread pipe and knob thread, which can shorten the overall length of the manifold handwheel and reduce the installation space. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] like Figure 1 - Figure 3 As shown, a manifold handwheel includes a handwheel seat 1. The lower part of the inner surface of the handwheel seat 1 is provided with a thread for mounting on the manifold. An externally threaded pipe 2 is fixed to the upper end of the handwheel seat 1. Multiple through grooves 3 are opened on the outer surface of the externally threaded pipe 2. A knob 4 is threadedly installed on the outer surface of the externally threaded pipe 2. An installation rod 5 is fixed to the top surface of the inner cavity of the knob 4. The installation rod 5 is existing technology and is used to connect with the manifold valve core. At the same time, due to the threaded connection between the knob 4 and the externally threaded pipe 2, the knob 4 can move up and down when rotated. Meanwhile, the opening degree of the manifold valve is controlled by the connection between the installation rod 5 and the valve core.
[0026] like Figure 4 and Figure 5 As shown, the thread pitch of the external threaded pipe 2 and the knob 4 is relatively long, so that the knob 4 does not need to rotate continuously when rotating, which can shorten the overall length of the water distributor handwheel and reduce the installation space.
[0027] Limiting blocks 6 are fixed on the upper inner surface of the external threaded pipe 2 and the upper inner surface of the knob 4. The limiting blocks 6 can prevent the knob 4 from being rotated too much, which would cause the threads of the knob 4 and the external threaded pipe 2 to not mesh. At the same time, they can also prevent the sealing gasket from being squeezed too much with the valve pipe when the valve core of the distributor is closed, which would cause the sealing gasket to deform, shorten its service life, and reduce the sealing effect, making the distributor more stable when in use.
[0028] like Figure 2 - Figure 4 As shown, the thread cross-sections of the external threaded tube 2 and the knob 4 are obtuse triangles, with the long side of the thread of the external threaded tube 2 located at the top and the long side of the thread of the knob 4 located at the bottom. Due to the mutual cooperation of the two obtuse angle threads, the device has a better self-locking ability than ordinary threads when in use, which can prevent the knob 4 from falling off from the external threaded tube 2 when the handwheel is in use, and increase the stability of the device when in use.
[0029] like Figure 2As shown, the through groove 3 extends upwards. Due to the design of multiple through grooves 3, the external threaded tube 2 can be divided into multiple threaded blocks. However, the multiple threaded blocks are all compatible with each other (that is, the knob 4 can still be threadedly connected to multiple threaded blocks). When the outer wall of the external threaded tube 2 is squeezed, the multiple threaded blocks can deform 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 thread installation. When installing the knob 4, first place the knob 4 on the through groove 3, and then press the knob 4 down. When pressing the knob 4, due to the design of multiple through grooves 3, the threaded blocks of the external threaded tube 2 can deform, so that the knob 4 can be directly fitted 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 fitted on the outer surface of the external threaded tube 2.
[0030] Furthermore, to facilitate production and reduce mold costs, the handwheel base 1, the external threaded tube 2, and the lower limiting block 6 are designed as a single unit. Similarly, the knob 4, the mounting rod 5, and the upper limiting block 6 are designed as a single unit. This allows the handwheel to be produced using only two molds, which are then assembled. This reduces the development and design costs of the molds. Additionally, the two-part design, along with the multiple through slots 3 on the outer surface of the external threaded tube 2, simplifies installation by pressing the upper part onto the lower part, thus shortening the handwheel's installation time and improving production efficiency.
[0031] The specific implementation of this embodiment is as follows: Since the handwheel of this water distributor is designed with two parts, upper and lower, only two sets of molds are needed during production. Multiple sets of molds are not required for production. Furthermore, since there are only two parts, these two parts only need to be assembled together during assembly, which reduces the development and design costs of molds and also improves the production efficiency of components.
[0032] During assembly, due to the design of the through slot 3, the handwheel can be installed simply by placing the upper part on the lower part and then pressing the upper part. This eliminates the need for multiple components, simplifies the installation steps of the water distributor, and improves the production efficiency of the handwheel.
[0033] When the handwheel is installed on the water distributor, first fix the valve core to the mounting rod 5, then thread the handwheel seat 1 onto the control port of the water distributor, and 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 handwheel seat 1 and the knob 4 in this utility model are all conventional designs, and this utility model will not elaborate on them in detail.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
