Description

Technical Field

[0001] The utility model relates to a water meter cover, in particular to an aluminum alloy water meter cover. Background Art

[0002] A water meter is a measuring instrument used to measure water flow. Existing household water meters typically use a rotary vane water meter for measurement. The water inlet of the water meter is connected to the water pipe at the water plant, and the water outlet is connected to the household water pipe. When the user releases water, the water flow hits the impeller, causing it to rotate circumferentially. At the same time, the impeller drives the gears to rotate, causing the flow rate to be displayed on the readout dial. Aluminum alloy is now often used to make meter covers due to its advantages of light weight, easy casting, and good corrosion resistance. The meter cover usually needs to be used in conjunction with the housing and cover. Under normal circumstances, non-staff members are prohibited from opening the cover to prevent it from affecting the accuracy of the water meter reading. Utility Model Content

[0003] The purpose of the utility model is to provide an aluminum alloy water meter cover, which can reduce the possibility of non-staff opening the meter cover and has better reliability.

[0004] The technical solution of the utility model is: an aluminum alloy water meter cover, including a cover body, connecting ears are provided on both sides of the cover body, a plurality of groups of evenly distributed limit columns for fixing the flip cover are provided on the cover body, a stepped groove for installing the glass cover is provided in the cover body, a positioning seat is provided on one side of the stepped groove for convenient positioning of the glass cover, an elastic clip is provided in the positioning seat, and a driving component for driving the elastic clip to contract is provided outside the cover body.

[0005] In the aforementioned aluminum alloy water meter cover, the elastic buckle includes a support tube parallel to the axis of the cover body, a spring is provided in the support tube, the end of the spring is connected to a positioning block that can move relative to the support tube, and a connecting rope is provided in the middle of the positioning block connected to the spring end.

[0006] In the aforementioned aluminum alloy water meter cover, the driving assembly includes a rotating ring provided on the outer wall of the cover, and an interface for connecting to a connecting rope is provided on the inner wall of the rotating ring.

[0007] In the aforementioned aluminum alloy water meter cover, the outer wall of the cover is provided with a guide groove corresponding to the rotating ring, the inner side of the guide groove is provided with a through hole for the connecting rope to pass through, and the outer side of the guide groove is provided with a sealing gasket.

[0008] Compared with the existing technology, the utility model positions the glass watch cover through the positioning seat, so that the glass watch cover can be stably installed in the stepped groove, and the positioning seat is provided with an elastic buckle, which can further lock the watch case, with better reliability, and the elastic buckle can be synchronously contracted through the driving component, which is easy to use.

DETAILED DESCRIPTION

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0015] Embodiment. An aluminum alloy water meter cover is composed of Figure 1-4 As shown, it includes a cover body 1, and connecting ears 2 are provided on both sides of the cover body 1. A plurality of groups of evenly distributed limiting columns 3 for fixing the flip cover are provided on the cover body 1. A stepped groove 5 for installing the glass cover is provided inside the cover body 1, and a positioning seat 6 for convenient positioning of the glass cover is provided on one side of the stepped groove 5. An elastic clip 7 is provided in the positioning seat 6, and a driving component for driving the elastic clip 7 to contract is provided outside the cover body 1.

[0016] The elastic buckle 7 includes a support tube 8 parallel to the axis of the cover body 1, a spring 9 is provided in the support tube 8, the end of the spring 9 is connected to a positioning block 10 that can move relative to the support tube 8, and a connecting rope 11 is provided in the middle of the end of the positioning block 10 connected to the spring 9.

[0017] The driving assembly includes a rotating ring 12 provided on the outer wall of the cover body 1 , and an interface 13 connected to the connecting rope 11 is provided on the inner wall of the rotating ring 12 .

[0018] The outer wall of the cover body 1 is provided with a guide groove 14 corresponding to the rotating ring 12 , the inner side of the guide groove 14 is provided with a through hole 15 for the connecting rope 11 to pass through, and the outer side of the guide groove 14 is provided with a sealing gasket 16 .

[0019] The principle of the present invention is as follows: When using this application, a slot corresponding to the elastic snap is provided at the upper end of the watch case. During use, the sealing ring and the glass cover are first placed in the stepped groove 5. The positioning seat 6 outside the stepped groove 5 can serve as a positioning limiter for the glass cover. Then, by driving the rotating ring 12 to rotate relative to the guide groove 14, the rotating ring 12 drives the connecting rope 11 to move, and the connecting rope 11 drives the positioning block 10 to move into the support tube 8. The cover 1 is then rotated relative to the watch case to complete the installation. When the cover is almost installed, the rotating ring 12 is driven to rotate relative to the guide groove 14 so that the rotating ring 12 no longer tightens the connecting rope 11. The positioning block 10 is ejected under the action of the spring 9 and, during the rotation process, is locked into the slot of the watch case, achieving fixation. Before unlocking, the rotating ring 12 must first be rotated so that the rotating ring 12 drives the positioning block 10 through the connecting rope 11 to compress the spring 9. Only then can the cover 1 be rotated; otherwise, the cover 1 cannot be rotated. This can reduce the possibility of non-staff opening the meter cover, and the reliability is better. A reversing block for reversing the connecting rope 11 is further provided in the supporting tube 8 to avoid damage to the connecting rope caused by the edge of the through hole 15, and the service life is longer. However, since the frequency of opening the water meter cover is low, a reversing block is not provided, and the application still has a good service life.
