Description

Anti-freezing water meter character wheel bin

Technical Field

The utility model belongs to the technical field of the water gauge manufacturing technology and specifically relates to indicate a water gauge print wheel storehouse prevents frostbite.

Background

The character wheel of the wet water meter is generally packaged in a transparent sealed cabin body, and the cabin body is filled with purified water to ensure the definition of a reading window of the water meter. When the product is sold to the north in winter, water in the bin body can be frozen in the transportation process, and the phenomenon that the character wheel bin is frozen due to freezing exists.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

An object of the utility model is to provide a water gauge character wheel storehouse prevents frostbite through piston assembly toward outer pressure release to solve the internal problem that leads to the frost crack because of water freezes in the storehouse. In order to achieve the above purpose, the utility model adopts the following technical scheme:

(II) technical scheme

The utility model provides a water gauge print wheel storehouse prevents frostbite, includes the storehouse body, the internal filling in storehouse has the pure water, storehouse body one side is equipped with the piston chamber with storehouse body intercommunication, piston intracavity portion is equipped with the one-way piston assembly who promotes towards piston chamber outside, piston chamber bottom is equipped with the internal thread, the cover is equipped with the hollow thread stopper on the internal thread, piston assembly includes piston and elastic spring, the cross-section of piston is the design of type of falling protruding, the piston lower extreme sets up in the hollow thread stopper, the elastic spring cover is established on the piston and the extrusion hollow thread stopper top.

Furthermore, a limiting boss is arranged above the inner wall of the piston cavity, and the upper end of the piston is clamped on the limiting boss.

Further, a sealing ring is sleeved on the piston.

(III) advantageous effects

Compared with the prior art, the utility model obvious advantage and beneficial effect have, particularly, the utility model discloses a piston assembly is toward outer pressure release to solve the internal problem that leads to the frost crack because of water freezes in the storehouse.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The present invention will be further described with reference to the accompanying drawings and the detailed description.

Referring to fig. 1, the anti-freezing water meter print wheel bin comprises a bin body 1, purified water is filled in the bin body 1, a piston cavity 2 communicated with the bin body 1 is formed in one side of the bin body 1, so that water is filled in the piston cavity 2, a piston assembly 3 which is pushed towards the outside of the piston cavity 2 in a one-way mode is arranged in the piston cavity 2, an internal thread 21 is formed in the bottom of the piston cavity 2, a hollow threaded plug 4 is sleeved on the internal thread 21, the piston assembly 3 comprises a piston 31 and an elastic spring 32, the cross section of the piston 31 is designed in an inverted convex shape, the lower end of the piston 31 is arranged in the hollow threaded plug 4, and the elastic spring 32 is sleeved on the piston 31 and extruded above the hollow threaded plug 4.

In order to enable the piston 31 to be installed in place in one step, a limiting boss 22 is arranged above the inner wall of the piston cavity 2, and the upper end of the piston 31 is clamped on the limiting boss 22.

In order to avoid water leakage, the piston 31 is sleeved with a sealing ring 33.

In winter transportation, in case the internal water of storehouse freezes the pressure grow, thereby just can promote piston 31 to move the pressure release towards piston cavity 2 outsides, makes the pressure in the storehouse body 1 unanimous or be close with external pressure to solve the storehouse and internal because of the water freezes and lead to the problem of frost crack, when the internal water of storehouse is dissolved, piston 31 resumes to the original state.

The utility model discloses a piston assembly is toward outer pressure release to solve the internal problem that leads to the frost crack because of water freezes in the storehouse.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
