Description

Technical Field

[0001] This utility model relates to the field of water meter technology, specifically to a rotating structure for a water meter cover. Background Technology

[0002] In water supply systems, water meters are important instruments for measuring water consumption and are widely used in the management of residential, industrial, and commercial water use. To protect the internal structure of the water meter from external environmental factors such as dust and rainwater, and to facilitate the reading of the meter data, water meters are usually equipped with a cover structure.

[0003] However, existing water meter covers use an integral fixed structure, with the cover plate and slots pre-set directly on the cover. This structure requires replacement of the entire cover when damaged, resulting in high maintenance costs. Therefore, a split-type rotating structure for easy maintenance of water meter covers is needed. Utility Model Content

[0004] The technical problem this invention aims to solve is that water meter covers are difficult to maintain, and this invention provides a split-type rotating structure for easy maintenance.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a water meter cover rotation structure, including a water meter body and a cover mechanism;

[0006] The watch cover mechanism includes a limiting sleeve and a rotating watch cover;

[0007] The rotating cover includes a positioning plate, a fixing sleeve, and a cover plate; the positioning plate is open in the center and the top surface is fitted with a fixing sleeve, and the top surface of the fixing sleeve is sealed by the cover plate;

[0008] After the positioning plate is placed on the top surface of the water meter body, the limiting sleeve is connected to the top of the water meter body through the positioning mechanism. The positioning plate is tightly attached between the water meter body and the limiting sleeve. The fixing sleeve extends out through the through hole at the top of the limiting sleeve, and a sealing ring is provided in the through hole.

[0009] As an improvement, the positioning mechanism includes an internal thread groove and an external thread groove;

[0010] The water meter body has a pre-set external thread groove, and the inner wall of the limiting sleeve has an internal thread groove that matches the external thread groove.

[0011] As an improvement, the outer wall of the limiting sleeve is also provided with anti-slip protrusions. Multiple anti-slip protrusions are evenly distributed along the circumference of the limiting sleeve to increase the friction when manually turning.

[0012] As an improvement, a pair of slots are provided on the inner wall of the top of the limiting sleeve, and a pair of locking blocks that match the slots are provided on the top surface of the positioning plate. After the cover is rotated and inserted into the limiting sleeve from bottom to top, the locking blocks are engaged in the slots.

[0013] As an improvement, the meter cover mechanism also includes a glass panel that is detachably mounted between the water meter body and the rotating meter cover.

[0014] As an improvement, a rubber ring is also included, with an annular groove on the inner wall of the rubber ring for inserting a glass panel.

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] 1. A rubber ring and glass panel sealing structure is set to effectively prevent moisture and dust from entering the water meter, thus extending the service life of the equipment;

[0017] 2. The limiting sleeve and positioning plate work together, and the locking block and slot limit the movement, enabling quick installation and removal of the rotating cover. The sealing rings placed between the components can effectively improve the sealing performance.

[0018] 3. Each component is designed to be detachable, making it easy to replace and clean, improving maintenance efficiency and reducing maintenance costs. Attached Figure Description
