Two-stage identification structure of the control lever of the water control valve

technical field

The utility model relates to a partial structure of a water control valve, in particular to an innovative form of a two-stage identification structure of a control rod of a water control valve.

Background technique

In terms of the structural design of the water control valve, the switching of the water supply opening and closing state and the adjustment of the water supply volume are mainly controlled by the vertical swing angle of a control lever, and the swing angle of the control lever corresponds to the faucet. It can be understood from general experience that the operating angle of the control lever is from the closed state to the fully open state, and the actuation angle stroke is actually quite short, generally between 25 degrees and 35 degrees.

Due to the abnormal climate and the shortage of water resources in recent years, how to save water in water-controlling products has always been an important topic of concern and breakthrough in the relevant industries; therefore, the handle of the faucet mentioned in the previous paragraph is in the process of manipulation, because When the user pulls up the handle with general strength, the handle can be easily reached to the angle position where the water volume is fully opened. In this way, water resources have been wasted and lost in the process of using water, and this problem is very serious. It is difficult to improve from the user side, because most users are usually difficult to change the long-standing habits. Therefore, if the above-mentioned problems can be improved by changing the structural design of the water control valve, it is still a relatively feasible solution. road.

Although some water control valve control levers have been developed in the relevant industry with segmented locking and positioning structures to achieve the water-saving function of segmented identification; existing water control valve control levers have segmented locking and positioning structures It is achieved by snapping the elastic top ball into the hole slot, but this kind of structure is because the elastic top ball is composed of a metal bead and a spring, and the volume that can be set by the metal bead and the spring must be quite small, convenient It can be assembled in the relatively narrow and limited control lever structure of the water control valve. Only in this way, there will inevitably be problems such as inconvenient assembly due to too small components, slow manufacturing time and lack of efficiency, and increased defect rate.

The main purpose of the utility model is to provide a two-stage identification structure of a control lever of a water control valve.

In order to achieve the above object, the utility model adopts the following technical solutions:

A two-stage identification structure for a control lever of a water control valve. The two-stage identification structure is set on a control lever of a water control valve that can swing vertically and corresponds to a rotating seat on the outer periphery of the control lever.

The technical features of the utility model to solve the problem mainly lie in that the two-stage identification structure includes: a radially penetrating accommodating hole, which is arranged at a space height position below the horizontal axis of the joystick in the form of radially piercing through the joystick; A step-shaped actuating rod is assembled and accommodated in the radial through accommodation hole in an axially displaceable and movable state. The step-shaped actuating rod includes a large-diameter section and a small-diameter section. The small-diameter section The outer diameter is relatively smaller than the large-diameter section, and the ends of the large-diameter section and the small-diameter section are respectively facing the two different ends of the radially penetrating accommodation hole; an internal accommodation groove is formed in the diameter in the form of an enlarged aperture. to a place in the through accommodation hole, and the location of the inner accommodation groove corresponds to the location of the small diameter section of the step-shaped actuating rod; an elastically expandable component is assembled and accommodated in the inner accommodation groove, The elastically expandable component has a piercing portion for the stepped actuating rod to pass through, the inner diameter of the piercing portion is larger than the outer diameter of the small-diameter section of the stepped actuating rod and smaller than the outer diameter of the large-diameter section, and the piercing portion The setting part has the elasticity of stretching and returning to the original shape; one abuts against the driving surface, and a part of the inner wall of the nozzle installed on the rotating seat is in the form of a vertical extension.

Detailed ways

As shown in Figures 1, 2, and 3, the preferred embodiments of the two-stage identification structure of the control lever of the water control valve of the present invention, but these embodiments are for illustration purposes only, and are not subject to this structure in the patent application limits. The two-stage identification structure A is set at a control lever 10 that can swing vertically on a water control valve B at a position corresponding to a rotating seat 20 on the outer periphery of the control lever 10. The control lever 10 has a The horizontal shaft 11 is used for pivoting in a nozzle 21 provided by the rotating base 20; the two-stage identification structure A includes the following components:

A radially penetrating accommodating hole 12 is provided at a spaced height below the horizontal axis 11 of the joystick 10 in the form of radially penetrating the joystick 10;

A step-shaped actuating rod 13 is assembled and accommodated in the radially penetrating accommodating hole 12 in an axially movable state. The step-shaped actuating rod 13 includes a large-diameter section 132 and a small-diameter section 134. The outer diameter of the small-diameter section 134 is relatively smaller than that of the large-diameter section 132 , and the ends of the large-diameter section 132 and the small-diameter section 134 are respectively directed toward two different ends of the radially penetrating accommodating hole 12 ;

An internal accommodating groove 14 is formed at a place in the radially penetrating accommodating hole 12 in the form of an enlarged aperture, and when the joystick 10 is in the default closed mode at an upright angle, the position of the internal accommodating groove 14 is the same as The position of the small diameter section 134 of the step-like actuating rod 13 is corresponding;

An elastically expandable component 15 is assembled and accommodated in the internal accommodation groove 14. The elastically expandable component 15 has a piercing portion 152 for the step-like actuating rod 13 to pass through. The inner diameter of the piercing portion 152 is larger than The outer diameter of the small-diameter section 134 of the stepped actuating rod 13 is smaller than the outer diameter of the large-diameter section 132, and the piercing portion 152 has elasticity that can be stretched and restored to its original shape;

One abuts against the driving surface 22, and a part of the inner wall of the nozzle 21 provided on the rotating seat 20 is in the form of a vertical extension. Contradiction forms the limiting effect of the displaceable state.

Wherein the elastically expandable component 15 can be in the form of a C-shaped fastener or an elastic ring (such as a rubber ring); this elastically expandable component 15 as shown in Figures 2 and 3 is a C-shaped As for the implementation form of the fastener, the material is not limited to metal or plastic.

As shown in Figure 3 in detail, one side of the control lever 10 is further provided with an assembly hole 16 at a spaced height below the horizontal axis 11, and the inner end of the assembly hole 16 communicates with the internal accommodating groove 14, so that it can be elastically expanded The assembly 15 can be assembled into the inner receiving groove 14 through the assembly hole 16 .

As shown in Figure 3, the setting axis of the stepped actuator 13 (shown by arrow X) and the setting axis of the horizontal axis 11 of the joystick 10 (shown by arrow Y) are arranged vertically to each other relation.

Through the design of the above-mentioned structural composition, the use and actuation of the two-stage identification structure A of the utility model is firstly shown in Figure 4. When the joystick 10 is in the default closed mode of the upright angle, the elastically expandable component 15 and the step-like structure are formed. The small-diameter section 134 of the actuating rod 13 is in the relative position; and when the joystick 10 is swinging to the default water supply mode of the inclination angle (as shown by the arrow L1 in Figure 5), the stepped actuating rod 13 penetrates the capacity in the radial direction. The inside of the hole 12 will be displaced toward the end of the small-diameter section 134 (as shown by the arrow L2 in Figures 5 and 6), so that the large-diameter section 132 will be gradually displaced to the position corresponding to the elastically expandable component 15, wherein, When the elastically expandable component 15 is displaced from the small-diameter section 134 to the large-diameter section 132, it will form a hindrance to the swing of the control rod 10, so the user must apply a relatively large force to control the lever 10. The joystick 10 swings to the maximum tilt angle (as shown by the arrow L3 in Figure 7, i.e. the state of the maximum water supply mode), and at the same time makes the elastically expandable component 15 expand and displace to the large-diameter section 132, thereby achieving a two-stage Hand feeling identification effect; and this effect is mainly to achieve the advantage and purpose of saving water, because the swing angle of the control lever 10 corresponds to the upward pull angle of the faucet handle, so through the two-stage identification structure of the utility model A technical feature, when the user pulls the faucet handle up to a certain angle (such as 15 degrees), the user's hand will have a sense of hindrance. At this time, if the user only needs to use a small amount of water, it will not continue Pull the handle upwards, and if the user needs to use a large amount of water, he must apply a greater force to pull the handle upwards to achieve it, thereby preventing the user from easily using the large water amount mode, achieving the advantages of saving water and Purpose.

In terms of manufacturing and assembling, the two-stage identification structure A of the present utility model has only a step-like actuating rod 13 and an elastically expandable component 15 that must be manufactured separately, and the two forms are quite simple and easy. For mass production, the radially penetrating accommodating hole 12 can be integrally formed by the control rod 10, and the inner wall of the nozzle 21 provided by the rotating seat 20 can be integrally formed against the driving surface 22; Before the control rod 10 is assembled into the nozzle 21 provided on the rotating seat 20, we can first assemble the elastically expandable component 15 into the internal accommodating groove 14 (note: the assembly hole 16 provided on one side of the control rod 10 can be used) ), and then insert the stepped actuating rod 13 into the radially penetrating accommodating hole 12, so that the elastically expandable component 15 can correspond to the position of the small diameter section 134 of the stepped actuating rod 13, and then The control rod 10 can be assembled into the nozzle 21 provided on the rotating base 20. After the assembly, the end of the large-diameter section 132 of the step-shaped operating rod 13 can be in contact with the inner wall of the nozzle 21 of the rotating base 20. Relying on the guide surface 22 to form a limit effect, so far the assembly procedure of the two-stage identification structure A is completed; Small parts, so the assembler can hold and assemble them easily and is not easy to drop. Although the volume of the elastically expandable component 15 is small, once it is assembled into the internal accommodation groove 14 set in the radially penetrating accommodation hole 12 That is, it is firmly limited, and it is quite convenient for the assembly and alignment operation. It can be seen that the two-stage identification structure A of the present invention has the advantages of simplified components, simple manufacture, and convenient assembly, and is practical and progressive.
