Description

Technical Field

[0001] This application relates to the field of water meter technology, and more specifically to a rotary vane water meter that is easy to observe. Background Technology

[0002] Rotary vane water meters are mainly used for measuring the total unidirectional water flow in small-diameter pipes. When in use, external water enters the meter casing through the water inlet. After passing through the filter screen, it drives the impeller in the impeller box to rotate. The rotation of the impeller will cause the dial to change and complete the counting. The water flowing into the impeller box then flows out through the outlet above the impeller box to the water pipe.

[0003] Patent document (CN218297272U) discloses a rotary vane water meter, as shown in the accompanying drawings of its specification. Figure 1 As can be seen, the reading area of ​​the rotary water meter is horizontally arranged, allowing the reader to position their head directly above and look down at the reading area to read the total water consumption. However, due to obstructions such as obstacles above or inside the meter, it is difficult for the reader to see the reading area from above and read the value. Additionally, some water meters are installed in dimly lit environments, making it difficult to see the numbers on the reading area without lighting.

[0004] Therefore, there is a need for a rotary water meter that allows for side-view readings, effectively prevents dust and dirt from obscuring the reading area, and is easy to observe in dimly lit environments. Summary of the Invention

[0005] The main objective of this application is to provide an easily observable rotary water meter, including a digit wheel housing. The digit wheel housing includes a housing body and a digit wheel measuring mechanism. The housing body has an inner cavity, and the digit wheel measuring mechanism is placed in the inner cavity. The digit wheel measuring mechanism includes a rotatable digit wheel assembly with numbers on its sidewalls. The digit wheel housing also includes a cover, a glass sealing cover, and a flip cover. The cover has a reading surface on which a set of numbers on the sidewalls of the digit wheel assembly are exposed. The reading surface is arranged at an angle. The glass sealing cover closes the opening of the inner cavity. The flip cover is rotatably mounted on the housing body. When the flip cover rotates to a predetermined angle, it covers or exposes the glass sealing cover. By setting the reading surface at an angle, it is easier for the reader to read from the side. By setting the flip cover to normally cover the glass sealing cover, it is possible to prevent the glass sealing cover from being covered by mud or dust and obscuring the reading surface. Compared with the prior art, it has the advantages of allowing side-view reading and effectively preventing dust and stains from blocking the reading area.

[0006] Another objective of this application is to provide a rotary water meter that is easy to observe, wherein the dial box further includes a light, which is fixedly installed on the side of the flip cover near the glass sealing cover. When the flip cover exposes the glass sealing cover, the light is on, and when the flip cover covers the glass sealing cover, the light is off. By setting the light, the advantage of being suitable for dim environments is achieved.

[0007] To achieve at least one of the above-mentioned inventive objectives, this application provides an easily observable rotary vane water meter, comprising a digit wheel housing. The digit wheel housing includes a housing body and a digit wheel measuring mechanism. The housing body has an inner cavity, and the digit wheel measuring mechanism is disposed within the inner cavity. The digit wheel measuring mechanism includes a rotatable digit wheel assembly, the sidewall of which has numbers. The easily observable rotary vane water meter includes:

[0008] The digit wheel box also includes a cover, a glass sealing cover, and a flip cover. The cover has a reading surface on which a set of numbers on the side wall of the digit wheel group are exposed. The reading surface is arranged at an angle. The glass sealing cover closes the opening of the inner cavity. The flip cover is rotatably mounted on the box body. When the flip cover is rotated to a predetermined angle, the flip cover covers or exposes the glass sealing cover.

[0009] In one or more embodiments of this application, the character wheel box further includes a light lamp, which is fixedly installed on the side of the flip cover near the glass sealing cover. When the flip cover exposes the glass sealing cover, the light lamp is on, and when the flip cover covers the glass sealing cover, the light lamp is off.

[0010] In one or more embodiments of this application, the top side of the box body has two protrusions, and the opposite ends of the two protrusions each have a notch. The flip cover has two spaced-apart protrusions on one side, and the opposite ends of the two protrusions each have a post. Each post is rotatably placed in the corresponding notch.

[0011] In one or more embodiments of this application, each of the inserts has a recessed hole on one side, and a corresponding protrusion has a receiving groove. The receiving groove communicates with the notch. The character wheel box also includes a trigger assembly disposed in the receiving groove. The trigger assembly includes a lifting member, an elastic member, and a momentary switch. The momentary switch is electrically connected to the lighting lamp. The elastic member is located between the lifting member and the momentary switch. When the flip cover rotates, the lifting member extends into the recessed hole or disengages from the recessed hole and abuts against the side wall of the insert. When the end of the lifting member away from the elastic member extends into the recessed hole, the elastic member is in an undeformed state, and the momentary switch is in an open state.

[0012] In one or more embodiments of this application, a protrusion having the receiving groove further has a lead channel communicating with the receiving groove.

[0013] In one or more embodiments of this application, the character wheel box further includes a battery compartment, which is fixedly installed on the side of the cover near the glass sealing cover. The battery compartment contains a power source, which is electrically connected to the jog switch and the lighting lamp.

[0014] In one or more embodiments of this application, the battery compartment has a battery cavity with an opening, and a lug is provided on both sides of the opening of the battery cavity. The digit wheel box also has an insulating rod through which the two lugs pass.

[0015] In this embodiment, the easily observable rotary water meter includes a digit wheel box, which comprises a box body and a digit wheel measuring mechanism. The box body has an inner cavity, and the digit wheel measuring mechanism is placed in the inner cavity. The digit wheel measuring mechanism includes a rotatable digit wheel assembly with numbers on the sidewalls of the digit wheel assembly. The digit wheel box also includes a cover, a glass sealing cover, and a flip cover. The cover has a reading surface on which a set of numbers on the sidewalls of the digit wheel assembly are exposed. The reading surface is arranged at an angle. The glass sealing cover closes the opening of the inner cavity. The flip cover is rotatably mounted on the box body. When the flip cover rotates to a predetermined angle, the flip cover covers or exposes the glass sealing cover. By setting the reading surface to be arranged at an angle, it is convenient for the reader to read from the side. By setting the flip cover to cover the glass sealing cover in normal operation, it is possible to prevent the glass sealing cover from being covered by mud or dust and thus obscuring the reading surface. Compared with the prior art, it has the advantages of being able to read from the side and effectively preventing dust and stains from blocking the reading area. Attached Figure Description

For example, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component, without departing from the teachings of the utility model concept. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] The terminology used herein is for the purpose of describing various embodiments only and is not intended to be limiting. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.

[0025] A schematic, easily observable rotary water meter, for reference. Figures 1 to 4 According to a preferred embodiment of the present invention, a rotary vane water meter that is easy to observe is provided, such as... Figure 1 and Figure 2 As shown, it includes a digit wheel box 10, which includes a box body 101 and a digit wheel measuring mechanism. The box body 101 has an inner cavity 1011, and the digit wheel measuring mechanism is placed in the inner cavity 1011. The digit wheel measuring mechanism includes a rotatable digit wheel assembly 102, and the sidewall of the digit wheel assembly 102 has numbers.

[0026] Specifically, such as Figure 1 and Figure 2As shown, the digit wheel box 10 also includes a cover 103, a glass sealing cover 104, and a flip cover 105. The cover 103 has a reading surface 1031 on which a set of numbers on the side wall of the digit wheel assembly 102 are exposed. The reading surface 1031 is arranged at an angle. The glass sealing cover 104 closes the opening of the inner cavity 1011. The flip cover 105 is rotatably mounted on the box body 101. When the flip cover 105 rotates to a predetermined angle, the flip cover 105 covers or exposes the glass sealing cover 104.

[0027] It should be noted that the tilt angle of the reading surface 1031 is preferably 45°. By setting the reading surface 1031 to an inclined arrangement, when there are obstacles near the easily observable rotary water meter, the observer can read the numbers on the dial group 102 by looking from the side. In addition, by setting the glass sealing cover 104, the sealing of the inner cavity 1011 is ensured without affecting the reading. By setting the flip cover 105 and covering the glass sealing cover 104 in normal condition, external dust, mud and other contaminants are prevented from adhering to the surface of the glass sealing cover 104 and affecting the reading. When reading is required, only the flip cover 105 needs to be opened and the numbers on the dial group 102 need to be read. Compared with the prior art, it has the advantages of side-view reading and effectively preventing dust and stains from blocking the reading area.

[0028] Furthermore, such as Figure 1 As shown, the character wheel box 10 also includes a light 106, which is fixedly installed on the side of the flip cover 105 near the glass sealing cover 104. When the flip cover 105 exposes the glass sealing cover 104, the light 106 is lit, and when the flip cover 105 covers the glass sealing cover 104, the light 106 is turned off.

[0029] It should be noted that by setting the lighting lamp 106, the problem of the reader having difficulty reading the water meter when it is installed in a dark environment due to the lack of lighting equipment can be effectively avoided. In addition, by linking the lighting lamp 106 to the movement of the flip cover 105, the waste of electricity is avoided. The lighting lamp 106 is only lit when reading the meter and provides illumination for the reader. Compared with the prior art, it has the advantage of being suitable for dark environments.

[0030] Furthermore, to enable the flip cover 105 to be rotatably mounted on the housing 101, as follows: Figure 1 , Figure 2 and Figure 3As shown, the top side of the box 101 has two protrusions 1012, and the opposite ends of the two protrusions 1012 each have a notch 10121. The flip cover 105 has two spaced protrusions 1051 on one side, and the opposite ends of the two protrusions 1051 each have a post 1052. Each post 1052 is rotatably placed in the corresponding notch 10121.

[0031] Furthermore, to ensure that the lighting lamp 106 turns on or off when the flip cover 105 rotates, as follows: Figure 3 and Figure 4 As shown, each of the inserts 1052 has a recess 10521 on one side, and a corresponding protrusion 1012 has a receiving groove 10122. The receiving groove 10122 communicates with the notch 10121. The character wheel box 10 also includes a trigger assembly 107, which is disposed in the receiving groove 10122. The trigger assembly 107 includes a lifting member 1071, an elastic member 1072, and a momentary switch 1073. The momentary switch 1073 is electrically connected to the lighting lamp 106. The elastic member 1072 is located between the lifting member 1071 and the momentary switch 1073. When the flip cover 105 rotates, the lifting member 1071 extends into the recess 10521 or the lifting member 1071 disengages from the recess 10521 and abuts against the side wall of the insert 1052.

[0032] It should be noted that, under normal conditions, the flip cover 105 covers the glass sealing cover 104, and at this time, when the end of the lifting member 1071 away from the elastic member 1072 extends into the recess 10521, the elastic member 1072 is in an undeformed state, and the jog switch 1073 is in an open state, that is, the lighting lamp 106 is disconnected from the power supply; when the reader needs to take a reading and opens the flip cover 105, the insert 1052 rotates by a predetermined angle. It should be pointed out that, due to the recess 10521... The side of 521 is conical, and the end of the lifting member 1071 facing away from the elastic member 1072 is spherical. The insert 1052 is cylindrical in shape. When the insert 1052 rotates, the side of the concave hole 10521 applies a force to the lifting member 1071, causing it to move a predetermined distance toward the jog switch 1073 and compress the elastic member 1072. At the same time, the elastic member 1072 transmits this pressure to the jog switch 1073, causing the jog switch 1073 to close. When the cover is closed, the circuit between the lighting lamp 106 and the power supply is connected, and the lighting lamp 106 lights up. As the flip cover 105 rotates further by a predetermined angle, the cylindrical sidewall of the insert 1052, excluding the recess 10521, contacts the lifting member 1071, keeping the elastic member 1072 in a compressed state. When the reader flips the cover 105 down again and covers the glass sealing cover 104, the recess 10521 is directly opposite the lifting member 1071, and the elastic member 1072 springs back to its original position. Under the action of force, the lifting member 1071 extends into the recess 10521 again, and at the same time, the elastic member 1072 returns to its undeformed state. Then, the jog switch 1073 is disconnected again after the pressure is removed, and the lighting lamp 106 is turned off. It should also be noted that when the lifting member 1071 is inserted into the recess 10521, it will provide a locking force and you can hear the impact sound of the lifting member 1071 hitting the wall of the recess 10521. This can also help the reader confirm that the flip cover 105 has been closed completely.

[0033] Furthermore, to provide space for placing the wires, such as Figure 4 As shown, a protrusion 1012 having the receiving groove 10122 also has a lead wire channel 10123, which is connected to the receiving groove 10122.

[0034] Furthermore, to provide a power source for the lighting lamp 106, such as... Figure 1 As shown, the character wheel box 10 also includes a battery compartment 1074, which is fixedly installed on the side of the cover 103 near the glass sealing cover 104. The battery compartment 1074 is equipped with a power source, which is electrically connected to the jog switch 1073 and the lighting lamp 106.

[0035] Furthermore, to prevent the battery from detaching from the battery compartment 1074 under gravity when the flip cover 105 is flipped down, as follows: Figure 1 As shown, the battery compartment 1074 has a battery cavity 10741 with an opening, and a lug 10742 is provided on both sides of the opening of the battery cavity 10741. The character wheel box 10 also has an insulating rod 108, through which the two lugs 10742 are inserted.

[0036] It should be noted that when the battery is placed into the battery cavity 10741, the insulating rod 108 is first pulled out from the lug 10742. After the battery is placed into the battery cavity 10741, the insulating rod 108 is then inserted into the holes of the two lugs 10742 to block the battery.

[0037] In summary, the easily observable rotary water meter described in the embodiments of this application is explained, which provides a side-viewable reading for the easily observable rotary water meter, effectively prevents dust and stains from blocking the reading area, and is suitable for dim environments, among other advantages.

[0038] It is worth mentioning that, in the embodiments of this application, the easily observable rotary water meter has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the easily observable rotary water meter provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.

[0039] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from these principles.
