Description

Technical Field

[0001] This utility model relates to the field of water pipes, and in particular to a frost-resistant stainless steel bathroom pipe fitting. Background Technology

[0002] Pipe freezing and bursting is a common phenomenon in cold seasons. In low-temperature environments, if the temperature is below the freezing point, water will freeze and expand in volume. When this powerful expansion force is confined inside a sturdy pipe, it will generate enormous pressure, eventually causing the pipe to burst.

[0003] Cracks caused by frozen water pipes are not obvious and are not easily detected in low-temperature environments. When the temperature rises, water can leak out along the cracks, wasting water resources and easily damaging bathroom products. The purpose of this utility model is to improve the existing pipe structure and propose a new pipe to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a frost-resistant stainless steel bathroom pipe fitting to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: it includes an expansion cavity, a connecting end, an elastic rubber tube, a movable plastic plate, and a fixed plastic plate. The connecting end is located on both sides of the expansion cavity and is integrally connected to the expansion cavity. The elastic rubber tube is located inside the expansion cavity, and both ends of the elastic rubber tube are connected to the connecting end. The movable plastic plate is disposed inside the expansion cavity and is connected to the outside of the elastic rubber tube. The fixed plastic plate is disposed inside the expansion cavity and is connected to the expansion cavity, with the fixed plastic plate abutting against the movable plastic plate.

[0006] To optimize the above technical solution, further measures are taken, including: magnet blocks, which are respectively set in the expansion cavity and the fixed plastic plate, and the magnet blocks repel each other. The repulsive force between the magnet blocks drives the fixed plastic plate to reset, preventing the fixed plastic plate from collapsing. The repulsive force between the magnet blocks can be changed by changing the material and size of the magnet blocks. Technicians can choose according to actual needs without having a substantial impact on the technical effect.

[0007] As a further improvement to the above technical solution: the expansion chamber is evacuated. The vacuum environment can reduce heat transfer and inhibit the freezing of water in the elastic rubber tube.

[0008] As a further improvement to the technical solution: the cross-sections of the movable and fixed plastic plates are arc-shaped. The arc-shaped structure slows down the freezing caused by heat conduction due to the small contact area between the movable and fixed plastic plates. At the same time, it can ensure that the movable and fixed plastic plates are in contact with each other with a small contact area. When the elastic rubber tube expands excessively, the arc surfaces of the movable and fixed plastic plates can also be staggered, providing additional expansion space for the elastic rubber tube.

[0009] As an improvement to the aforementioned technical solution: the length direction of the movable plastic plate is parallel to the length direction of the elastic rubber tube. Such a movable plastic plate can strengthen the elastic rubber tube and prevent the elastic rubber tube from being excessively deformed in a normal temperature environment.

[0010] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: This utility model provides a frost-resistant stainless steel bathroom pipe fitting. By setting the pipes in layers and using fixed and movable plastic plates to separate the pipes, it can slow down the freezing speed and allow the pipes to adapt to the volume expansion caused by freezing, thus preventing the pipes from freezing and cracking. It has practical significance and promotional value. Attached Figure Description

The illustrative embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an undue limitation of the present invention. In the drawings: Figure 1 A three-dimensional structural schematic diagram of this utility model; Figure 2 This is a schematic diagram of the cross-sectional structure of the present invention; In the diagram: Expansion chamber - 100, Connecting end - 200, Elastic rubber tube - 300, Movable plastic plate - 400, Fixed plastic plate - 500, Magnet block - 600 Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0013] Please see Figure 1 and Figure 2This utility model provides a frost-resistant stainless steel bathroom pipe fitting, including an expansion cavity 100, a connecting end 200, an elastic rubber tube 300, a movable plastic plate 400, a fixed plastic plate 500, and a magnet block 600.

[0014] The connecting ends 200 are located on both sides of the expansion cavity 100 and are integrally connected to the expansion cavity 100.

[0015] The elastic rubber tube 300 is located inside the expansion chamber 100, and both ends of the elastic rubber tube 300 are connected to the connecting end 200 respectively. The expansion chamber 100 is evacuated.

[0016] The movable plastic plate 400 is disposed inside the expansion cavity 100. The movable plastic plate 400 is connected to the outside of the elastic rubber tube 300, and the length direction of the movable plastic plate 400 is parallel to the length direction of the elastic rubber tube 300.

[0017] The fixed plastic plate 500 is disposed inside the expansion cavity 100 and is connected to the expansion cavity 100. The fixed plastic plate 500 abuts against the movable plastic plate 400. The cross-sections of the movable plastic plate 400 and the fixed plastic plate 500 are arc-shaped.

[0018] The magnet blocks 600 are respectively disposed on the expansion cavity 100 and the fixed plastic plate 500, and the magnet blocks 600 repel each other.

[0019] Working principle: At room temperature, water can flow freely through the elastic rubber tube 300 via the connection end 200. Since the side of the elastic rubber tube 300 is restricted by the movable plastic plate 400, the elastic rubber tube 300 will not undergo excessive deformation and will not affect the normal use of the pipe.

[0020] Because the expansion chamber 100 is evacuated and the contact area between the fixed plastic plate 500 and the movable plastic plate 400 is small, the water flow inside the elastic rubber tube 300 is less affected by the external environment, which can slow down the freezing speed and ensure that the elastic rubber tube 300 can respond to freezing in a timely manner. After freezing occurs, the elastic rubber tube 300 deforms outward, causing the movable plastic plate 400 to press against the fixed plastic plate 500, thereby adapting to the volume expansion caused by water freezing and preventing freezing and cracking. After the ice melts, the fixed plastic plate 500 and the movable plastic plate 400 move away from each other under the mutual repulsion of the magnet 600, causing the elastic rubber tube 300 to return to its original position.

[0021] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
