Description

Technical Field

[0001] The utility model relates to the field of instrument equipment, in particular to a water meter with a protective shell. Background Art

[0002] A water meter is an instrument for measuring water flow, most of which measure the cumulative flow of water. It is generally divided into two categories: volumetric water meter and velocity water meter. Currently, a flip-top protective shell is often installed on the top of a water meter, but the protective shell is prone to breakage at the hinge. Replacing the entire water meter is not only wasteful but also complicated and inconvenient. Therefore, a water meter with a protective shell is needed.

[0003] When the existing water meter is in use, it is inconvenient to replace the damaged water meter protective shell, and it is inconvenient to install and connect the water pipe. Therefore, a water meter with a protective shell is urgently needed. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a water meter with a protective shell to solve the problem that the existing water meter is inconvenient to replace the damaged water meter protective shell and inconvenient to install and connect the water pipe.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a water meter with a protective shell, comprising a water meter shell, a card slot is opened inside the water meter shell, a protective shell is installed on the top of the water meter shell, and a spring block is movably connected inside the protective shell.

[0006] The outer wall of the water meter housing is fixedly connected to a water inlet pipe, the outer wall of the water inlet pipe is fixedly connected to a sleeve, one end of the sleeve is fixedly connected to a receiving plate, and one side of the receiving plate is fixedly connected to a clamping block, the outer wall of the sleeve is movably connected to a threaded sleeve, a connecting pipe is installed inside the water inlet pipe, and a limiting hole is provided inside the connecting pipe.

[0007] Preferably, the protective shell is of open-hole design, and the spring block and the protective shell form a sliding structure.

[0008] Preferably, the spring block is snap-connected to the water meter housing via a slot, and the spring block is symmetrically arranged with respect to the central axis of the protective housing.

[0009] Preferably, the outer wall of the sleeve is provided with threads, and the sleeve is threadedly connected to the threaded sleeve.

[0010] Preferably, the connecting pipe is snap-connected with the water inlet pipe, and the clamping block is snap-connected with the connecting pipe via a limiting hole.

[0011] Preferably, the receiving piece is elastically designed and evenly distributed along one end of the outer wall of the sleeve.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model is provided with a water meter housing, a card slot, a protective housing and a spring block. By moving the protective housing and inserting the bottom of the protective housing into the water meter housing, the inner wall of the water meter housing squeezes the spring block, driving the spring block to be received into the protective housing. By rotating the protective housing, the position of the spring block and the card slot are overlapped. Under the action of the spring, the spring block can be stuck in the card slot for limiting, which makes it easy to replace and install the protective housing.

[0014] 2. The utility model is provided with a water inlet pipe, a sleeve column, a receiving piece, a clamping block, a threaded sleeve, a connecting pipe and a limiting hole. By moving the connecting pipe and inserting one end of the connecting pipe into the water inlet pipe, and rotating the threaded sleeve, the threaded sleeve can be rotated and moved along the sleeve column, so that the threaded sleeve squeezes the protrusion of the receiving piece, so that the receiving piece bends, thereby driving the clamping block to be clamped in the limiting hole for limiting, thereby facilitating the installation and connection of the connecting pipe.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0022] The following describes an embodiment of the utility model based on its overall structure.

[0023] See also Figure 1-5A water meter with a protective shell includes a water meter shell 1, a card slot 2 is opened inside the water meter shell 1, a protective shell 3 is installed on the top of the water meter shell 1, and a spring block 4 is movably connected inside the protective shell 3. The protective shell 3 is an open-hole design, and the spring block 4 and the protective shell 3 form a sliding structure. The spring block 4 is engaged with the water meter shell 1 through the card slot 2, and the spring block 4 is symmetrically arranged with the central axis of the protective shell 3, so that the protective shell 3 can be easily replaced and installed.
