Description

TECHNICAL FIELD

[0001] The utility model relates to a character wheel box, especially a character wheel box convenient for vacuumizing and water filling. BACKGROUND

[0002] In the production of the water meter core character wheel box, water is filled in the box, because if there is air, it will cause fog, affecting the normal reading, but because the core is usually stored for a period of time before use, with the change of temperature, the water in the character wheel box will be slowly squeezed out, resulting in air in the character wheel box.

[0003] After the intelligent assembly line, the core needs to be vacuumized and water filled, at this time, due to the effect of air pressure, the air in the character wheel box will expand, so the water in the character wheel box will be squeezed out first, and after pressure relief, the air in the character wheel box will not be discharged, sometimes more, which cannot achieve the purpose of vacuumizing and water filling. SUMMARY

[0007] Further, the small hole is arranged through the cover plate.

[0008] Further, a window for observing the reading of the internal character wheel group is arranged at the top of the character wheel box body.

[0009] Further, an installation hole for installing the character wheel shaft is arranged on the inner wall of one side of the character wheel box body, and a through hole for the character wheel shaft to pass through is arranged on the other side.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] The utility model discloses a rubber plug is set up in the bottom of the character wheel box body, and the small hole is opened in the bottom of the cover plate corresponding position simultaneously, so that when pumping water pressure relief, the water of character wheel box outside will press the rubber plug inwards, and the water of character wheel box outside will flow into the inside of character wheel box from the small hole, to reach the effect of filling water, after finishing pumping water, when the internal and external pressure balance, because the rubber plug has blocked the small hole, the water in the inside of character wheel box will not flow out, to reach the purpose of filling water.

[0017] In order to make the purpose, technical scheme and advantage of the utility model embodiment more clear, the following will combine the drawing in the utility model embodiment, and the technical scheme in the utility model embodiment is clearly and completely described, obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiment. The components of the utility model embodiment described and shown in the drawing here can be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiment of the utility model provided in the drawing is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of the utility model protection.

[0019] It should be noted that: similar signs and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0020] In the description of the utility model, it needs to explain, the term "center", "upper", "lower", "left", "right", "vertical", "horizontal", "internal", "external" and so on indicate the orientation or position relation is based on the orientation or position relation shown in the drawing, or it is the orientation or position relation that the utility model product uses usually, only is for the convenience of describing the utility model and simplifying the description, and cannot indicate or imply that the indicated device or element must have a particular orientation, construct and operate, therefore cannot be understood as the limitation of the utility model.

[0021] It needs to explain, the term "first", "second" is only used for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more features. In the description of the application, the meaning of "multiple" is two or more than two, unless otherwise specifically limited.

[0022] In addition, the terms "horizontal", "vertical" and other terms do not mean that the component must be absolutely horizontal or suspended, but can be slightly inclined. As "horizontal" only means that its direction is more horizontal relative to "vertical", not that the structure must be completely horizontal, but can be slightly inclined. Embodiment
