TECHNICAL FIELD
[0001] The present application relates to a tap control lever, belonging to the technical field of tap operating tools. BACKGROUND
[0002] There are many tap wells indoors and outdoors, and the tap is arranged at the bottom of the well. The operator needs to bend down or enter the well to touch the tap handle and then operate it. This operation mode not only consumes physical strength, but also has the risk of bruising and falling.
[0003] According to the common knowledge in the art, these tap wells are in various environments. For example, in the winter environment in the north, the tap well needs to be covered with a thermal insulation layer to prevent the tap at the bottom of the well from being frozen. When the tap needs to be operated, the thermal insulation layer in the well needs to be removed or lifted, and then the operator needs to bend down to turn the tap handle. The operation is very inconvenient, and some operators forget to restore the thermal insulation layer or do not restore it at all, which causes the tap in the well to be frozen or has the risk of being frozen.
[0004] For example, the tap well arranged in the green belt is prone to missing or damage. Leaves, grass or soil enter the well and cover or bury the tap or the thermal insulation layer in the well, especially during the construction of the green belt. It is obvious that this brings many difficulties to the maintenance of the tap well and makes the operation of the tap very troublesome.
[0005] In other cases, garbage or water enters the tap well, which brings inconvenience to the operation of the tap and the maintenance of the tap well.
[0006] In order to facilitate the operation of the tap, the operator generally uses a tap operating lever. The operating lever is a straight rod structure, and the lower end is provided with a fork-shaped clamp jaw or a clamping plate structure. When in use, the operator stands beside the tap well and clamps the lower end of the operating lever jaw or clamping plate against the tap handle instead of clamping it, and then turns the handle at the upper end of the operating lever to operate the tap. Because the connection mode is clamped against, the operating lever is also easy to be separated from the tap handle, and cannot be used as a long-term connection device. The existing operating lever is a temporary operating tool, which is not always arranged in the tap well, and is not connected to the tap. Therefore, the existing operating lever is helpless when facing the above problems.
[0007] The prior art cannot meet the requirements. SUMMARY

[0012] As an additional technical feature of the present application, the bayonet comprises a bayonet entrance, a bayonet stopper and a bayonet interior, the bayonet interior of the bayonet communicates to the lower end face of the side wall of the sleeve through the bayonet entrance, the bayonet stopper is arranged at the lower edge of the bayonet interior and the side edge of the bayonet entrance.
[0013] As an additional technical feature of the present application, the pin is inserted into the bayonet interior from the pin hole until the bayonet entrance.
[0014] As an additional technical feature of the present application, the width of the guide groove is 2 / 5 to 4 / 5 of the outer diameter of the pin, part of the side wall of the pin is guided into the bayonet along the depth direction of the guide groove.

[0029] The technical solution of the tap control rod of the present application will be further described in detail below with reference to the embodiments shown in the drawings.
[0030] As shown in the drawings Figure 1 and the drawings Figure 2 , a tap control rod, comprising a sleeve 9, a single-joint cross shaft universal joint 8, a rotating rod 6 and a control rod handle 4, the rotating rod 6 is a straight rod with fixed length, the lower part of the sleeve 9 is connected with the valve handle 201 of the tap 2, the upper end of the sleeve 9 is connected with the output end of the single-joint cross shaft universal joint 8, the input end of the single-joint cross shaft universal joint 8 is connected with the lower end of the rotating rod 6, the upper end of the rotating rod 6 is connected with the control rod handle 4, rotating the control rod handle 4 can make the rotating rod 6 rotate, and in turn drive the single-joint cross shaft universal joint 8, the sleeve 9 and the valve handle 201 of the tap 2 to rotate, realizing the operation of the tap 2.
[0031] According to the drawings Figure 1 , the drawings Figure 5 and the drawings Figure 9 , it can be seen that the rotating rod 6 is an elongated rod structure, and the control rod handle 4 connected with the upper end thereof is a straight rod, and the two form a T-shaped connection structure.
[0032] When the operating handle 4 of the tap control rod is operated, a transverse force is usually generated on the operating handle 4, and other accidental factors may also cause a similar transverse force on the upper middle section of the rotating rod 6 or the operating handle 4, such as construction site construction or tap well maintenance, etc. The single-joint cross shaft universal joint 8 described in the application can eliminate the damage of the tap control rod itself or the tap caused by the transverse force on the upper middle section of the rotating rod 6 or the operating handle 4, and does not affect the transmission of the axial torque. In addition, after the single-joint cross shaft universal joint 8 is arranged, the tap control rod can also be inclined to operate, so that the operation of the tap is very flexible and can better meet the operation requirements of the operator. Please refer to the accompanying drawings. Figure 9 If the tap control rod does not use the single-joint cross shaft universal joint 8, but uses the existing straight rod structure, and the operating handle 4 is displaced to the left under the transverse force, the sleeve 9 at the lower end of the operating handle 4 will definitely rotate around a straight line perpendicular to the bayonet 11, and then break the tap handle 201 or the tap 2 and the pipeline 1, which will cause serious consequences.
[0033] According to the common knowledge in the art, the tool for operating the tap does not need to be precise, and the precision requirement of the tap control rod described in the application for the single-joint cross shaft universal joint 8 is not high, which is beneficial to reduce the manufacturing cost.
[0034] The sleeve 9 and the tap handle 201 are connected in a bayonet type connection manner, which can conveniently and reliably realize the connection or disconnection between the sleeve 9 and the tap handle 201.
[0035] Please refer to the accompanying drawings. Figure 1 to Figure 4 The sleeve 9 is a sleeve structure with a closed upper end and an open lower end, two through bayonets 11 are arranged on the side wall of the sleeve 9 in the radial direction, a guide groove 15 is arranged on the side wall of the sleeve 9 in the circumferential direction, the opening direction of the guide groove 15 faces the lower end of the sleeve 9, one through pin hole 10 is arranged on the closed end of the sleeve 9 at the upper part of each bayonet 11, the pin hole 10 communicates with the bayonet 11 and the guide groove 15, and a plug-in pin 7 is arranged in each pin hole 10.
[0036] As can be seen from the drawings, the part of the pin 7 inserted into the sleeve 9 is the main body part of the pin 7, and the outer diameter of the upper end of the pin 7 is larger than the outer diameter of the main body part of the pin 7, so that the pin 7 cannot completely enter the sleeve 9.
[0037] As shown in the drawings, Figure 4The embodiment of the shown bayonet 11 is shown in the figure, the bayonet 11 includes a bayonet entrance 12, a bayonet stop 13 and a bayonet interior 14, the bayonet interior 14 of the bayonet 11 is communicated to the lower end surface of the side wall of the sleeve 9 through the bayonet entrance 12, the bayonet stop 13 is arranged at the lower edge of the bayonet interior 14 and the side edge of the bayonet entrance 12, as can be seen from the figure, for the convenience of manufacture, the bayonet stop 13 is also a part of the side wall of the sleeve 9.
[0038] In the attached Figure 3 and the attached Figure 8 , the pin 7 has been installed in place, the pin 7 is inserted into the bayonet interior 14 from the pin hole 10 until the bayonet entrance 12.
[0039] As shown in the attached Figure 3 and the attached Figure 8 , the width of the guide groove 15 is 2 / 5 to 4 / 5 of the outer diameter of the pin 7, part of the side wall of the pin 7 is guided into the bayonet 11 along the depth direction of the guide groove 15.
[0040] As shown in the attached Figure 5 , the water valve 2 is connected with the pipeline 1, the valve handle 201 of the water valve 2 is a two-wing symmetrical structure, in order to realize the connection between the sleeve 9 and the valve handle 201, the two bayonets 11 are arranged in rotational symmetry about the central symmetry axis of the sleeve 9.
[0041] For the case that the valve handle 201 of the water valve 2 is a wrench type asymmetric structure, according to the common knowledge in the art, the wrench handle for operating the valve switch is on one side of the valve core rotating shaft, then one bayonet 11 can be used to connect the valve handle 201, and the other bayonet 11 is idle.
[0042] To install the water valve control rod described in the present application in place, first, the water valve control rod 3 is erected, the lower end sleeve 9 of the water valve control rod 3 is aligned with the valve handle 201 of the water valve 2, please refer to the attached Figure 5 , then the water valve control rod 3 is moved downward, the central part of the valve handle 201 enters the middle sleeve interior of the sleeve 9, the two wings of the valve handle 201 enter the bayonet interior 14 from the bayonet entrance 12 of the bayonet 11, as shown in the attached Figure 6 , then the sleeve 9 is rotated, the lower edge of the two wings of the valve handle 201 is located above the bayonet stop 13, forming a three-sided enclosure structure, as shown in the attached Figure 7 , finally, the pin 7 is inserted, as shown in the attached Figure 8 , forming a four-sided enclosure structure so that the two wings of the valve handle 201 cannot be separated from the bayonet interior 14 of the bayonet 11, and the torque is well transmitted when the valve is opened and closed, after the installation is completed, as shown in the attached Figure 9 .
[0043] When it is necessary to remove the water valve control lever 3, first pull the pin 7 upwards, and then follow the reverse process of the above installation process. It is very convenient.
[0044] As attached Figure 10 As shown, in the valve well, the water supply valve 2 is connected to the pipe 1. The water supply valve control rod 3 described in this application has been connected to the valve handle 201 of the water supply valve 2. An insulation layer 5 is laid on top of the water supply valve 2, and the water supply valve control rod 3 is also wrapped by the insulation layer 5. The control rod handle 4 is located in the water supply valve well, and its top does not protrude from the valve well. It is located on the upper side of the insulation layer 5 in the water supply valve well. When operating the water supply valve 2, it is not necessary to pry open or lift the insulation layer 5. Simply turning the control rod handle 4 can operate the water supply valve 2 without damaging the insulation layer 5. Figure 10 As can be seen, compared with the valve handle 201, the control lever handle 4 is closer to the valve well opening, which is convenient for operation. According to common knowledge in the field, the insulation layer 5 is made of soft material, so it will not hinder the rotation of the water valve control lever 3. When other debris enters the valve well, these debris will be on top of the insulation layer 5 and will still not affect the operation of the water valve 2, which has a very good technical effect.
[0045] Of course, other options and developments, as well as equivalent devices that we can foresee, are possible without departing from the framework of this application.
