Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of timing valves, and particularly relates to an indicating dial and a time status indicating device based on the same. Background Art
[0002] A timing valve is a valve that can automatically open or close at a preset time point. Such valves are widely used in industrial, agricultural, residential, and commercial environments to control the flow of fluids (such as water, gas, steam, oil, etc.). The use of timing valves can improve the automation level of the system, reduce the need for manual operation, and also help to save resources and improve efficiency.
[0003] Currently, some timing valves are products that rely on a pure mechanical mechanism to drive the time status display. There are mainly two time indication methods for such products: one type uses a traditional thin pointer and dial design. When reading the time, since the pointer is thin and the dial content is complex, it is difficult to read the time; the other type uses a red translucent part to replace the pointer, and the red part is rotated out when the time needs to be indicated. However, its red part mainly relies on a protruding small pointer to indicate the time, and although the large area of red can play an obvious eye-catching role, it is easy to cause confusion for the accurate indication of time.
[0004] Although both time indication methods can better achieve time indication, when they are applied to special fields, especially fields such as gas timing valves that need to write operation guides, warning messages, and other text information, since the same interface needs to display not only scales but also text such as operation methods and warning messages, the font and scales are very small. Users often have difficulty quickly and accurately reading the time, and it is easy to ignore important warnings, thereby increasing the risk of misoperation and the possibility of accidents. These problems are more prominent when there is a certain distance between the user and the dial, making the time display blurred and the warning messages inconspicuous, thus affecting the safe use of the product. Content of the Utility Model
[0005] The purpose of the utility model is to provide an indicating dial and a time status indicating device based on the same, so that the time scale is in a hidden state without operation, and the warning messages and operation methods can be displayed to the maximum extent.
[0006] An indicating dial in this solution includes a transparent cover and a base with a central hole. A circular groove is provided on the upper surface of the base. An opaque prompt plate is fixedly connected to the upper surface of the base. An avoidance hole is provided on the prompt plate. The pointer, warning words, and operation methods are engraved on the upper surface of the prompt plate around the avoidance hole. A notch extending to the avoidance hole is provided on the outer wall of the prompt plate; a fixing rod extending downward is provided at the center of the transparent cover. The fixing rod is rotationally connected to the central hole through the avoidance hole; a scale plate is fixedly connected to the fixing rod. The scale plate is located in the groove and below the prompt plate. Time scales are provided on the scale plate. An arc-shaped avoidance opening coaxial with the fixing rod is provided on the scale plate. A cut is provided on the scale plate. The cut extends from one end of the avoidance opening to the outer edge of the scale plate. The free end at the cut of the scale plate is located at the notch.
[0007] The working principle and beneficial effects of this solution: In this solution, more time scales are separately set on the scale plate, and then the pointer, warning words, and operation methods are set on the indicating dial, so that the pointer, warning words, operation methods, and time scales can all be set larger for easy viewing. Before use, fixedly connect the base of the indicating dial to the movement of the mechanical timing valve, and connect the fixing rod to the movement shaft.
[0008] In the initial state, the scale plate is hidden below the prompt plate, making the warning words and operation methods on the prompt plate clearly visible, which can better prompt the user to perform safe operations. When the indicating dial works, by rotating the transparent cover clockwise, the transparent cover drives the scale plate to rotate. The scale plate starts to rotate out and then blocks part of the prompt plate. When the scale plate rotates out, the time scales on the scale plate are displayed, and the pointer corresponding to the time scale is the current timing time. When the transparent cover is released, the torsion spring on the movement starts to release elastic force. Under the action of a specific mechanism on the movement, the movement starts to drive the scale plate and the transparent cover to rotate in the opposite direction. At this time, the indicating dial starts to enter the timing function (countdown).
[0009] In the indicating dial of this solution, during the entire countdown process, the larger time scales are gradually covered by the opaque prompt plate, and the scale display becomes less and less, truly interpreting the concept of countdown. The pointer is specially highlighted and fixed, and the user can accurately read the corresponding remaining time.
[0010] Further, the distance between the scale plate and the bottom of the groove is 1.5 - 2.5 mm. This helps the scale plate rotate more smoothly.
[0011] Further, the scale plate is transparent. By setting the scale plate to be transparent, even if the time scales of the scale plate rotate out above the indicating dial, the warning words and operation methods on the prompt plate can still be seen, thus prompting the user again and further improving the use safety.
[0012] Furthermore, a protective cover is sleeved on the transparent cover. The provision of the protective cover helps to protect the transparent cover.
[0013] The present application also provides a time status indicating device, specifically: the time status indicating device includes the above-mentioned indicating dial.
[0014] Furthermore, the time status indicating device further includes a movement provided with a torsion spring. The movement also includes a movement shaft for driving a fixed rod, and the movement shaft is fixedly connected to the fixed rod. The base is fixedly connected to the movement. After manually rotating the transparent cover, the torsion spring in the movement starts to contract; when the transparent cover is released, the torsion spring starts to release its elastic force, and the torsion spring drives the movement shaft, the scale dial, and the transparent cover to start rotating in the opposite direction. At this time, the device starts to enter the timing function (countdown).
[0015] Furthermore, the base is fixedly connected to the movement by fixing screws. Through the provision of the fixing screws, the base can be quickly connected to and detached from the movement.
[0016] Furthermore, a threaded hole is provided at the center of the top of the movement shaft. A fastening screw is threadedly connected in the threaded hole. A through hole for the movement shaft to pass through is provided in the axial direction of the fixed rod. A guiding hole coaxial with the through hole is provided at the top of the transparent cover and the two are connected. The fastening screw passes through the guiding hole and is threadedly connected to the threaded hole. Through the provision of the threaded hole and the guiding hole, the fixed rod can be quickly fixed to or detached from the movement shaft.
[0017] Furthermore, a circular placement groove is provided at the top of the transparent cover. The placement groove is coaxial with the guiding hole. The diameter of the placement groove is larger than the aperture of the guiding hole. A washer is provided in the placement groove. The fastening screw passes through the washer and the guiding hole and is fixedly connected to the threaded hole. Through the provision of the placement groove and the washer, it can better ensure that the fixed rod is fixed to the movement shaft.
[0018] Furthermore, a cap is provided in the placement groove, and the washer and the fastening screw are located inside the cap. Through the provision of the cap, the washer and the fastening screw are prevented from being directly exposed outside, making the top of the time status indicating device more beautiful.

The cut extends from one end of the avoidance opening to the outer edge of the dial 4. The free end of the cut of the dial 4 is located at the notch.
[0026] Embodiment 2 is basically as shown in the attached Figure 2 figure: A time status indicating device, the difference from Embodiment 1 is only that: it further includes a movement 1 provided with a torsion spring. The movement 1 further includes a movement shaft for driving the fixing rod 6. The movement shaft is fixedly connected with the fixing rod 6. The base 2 is fixedly connected to the movement 1 through a fixing screw 3. A threaded hole is provided at the center of the top of the movement shaft. A fastening screw 10 is threadedly connected in the threaded hole. A through hole for the movement shaft to pass through is provided in the axial direction of the fixing rod 6. A guide hole coaxial with the through hole is provided at the top of the transparent cover 7 and the two are communicated. A circular placement groove is provided at the top of the transparent cover 7. The placement groove is coaxial with the guide hole. The diameter of the placement groove is larger than the aperture of the guide hole. A washer 9 is provided in the placement groove. The fastening screw 10 passes through the washer 9 and the guide hole and is fixedly connected to the threaded hole. A cap 11 is detachably connected in the placement groove. The washer 9 and the fastening screw 10 are located inside the cap 11 to improve the aesthetics.
[0027] Taking Embodiment 2 as an example, the specific implementation process is as follows: A larger number of time scales 15 are separately set on the dial 4, and then the pointer 13, warning words 14, and operation methods 12 are set on the indicating dial, so that the pointer 13, warning words 14, operation methods 12, and time scales 15 can all be set to be larger for easy viewing. Before use, the base 2 of the indicating dial is fixedly connected to the movement 1 of the mechanical timing valve through the fixing screw 3, and the fixing rod 6 is connected to the movement shaft through the fastening screw 10.
[0028] In the initial state, the dial 4 is hidden under the prompt disc 5, so that the warning words 14 and operation methods 12 on the prompt disc 5 are clearly visible (as shown in the appendix Figure 3 ), which can better prompt the user to perform safe operations. When the indicating dial works, by rotating the transparent cover 7 clockwise, the transparent cover 7 drives the dial 4 to rotate, and the dial 4 starts to spin out and thus blocks part of the prompt disc 5. When the dial 4 spins out, the time scales 15 on the dial 4 are displayed, and the time corresponding to the pointer 13 on the time scales 15 is the current timing time. When the transparent cover 7 is released, the torsion spring on the movement 1 starts to release elastic force, and under the action of a specific mechanism, the movement 1 starts to drive the dial 4 and the transparent cover 7 to rotate in opposite directions. At this time, the indicating dial starts to enter the timing function (countdown), as shown in the appendix Figure 4 .
