Description

A water pipe screw connection mechanism for a water purifier

technical field

The utility model relates to a water pipe screw connection mechanism used in a water purifier, which belongs to the transformation technology of the water pipe screw connection mechanism used in a water purifier.

Background technique

At present, most screw connections on the market use the friction between the threads and the rising angle to prevent the threads from loosening after tightening, but this solution will still loosen when encountering a large impact pressure, which cannot solve the impact pressure situation; Some do screw hole on container cover and container body, directly fix with screw and prevent the loosening of screw thread, but this scheme makes loading and unloading water pipe very complicated.

Utility model content

The purpose of this utility model is to provide a water pipe screw connection mechanism for water purifiers with simple and reasonable structure and simple process requirements in consideration of the above problems. The utility model has the advantages of convenient installation, good sealing performance and resistance to pressure impact.

The technical scheme of the utility model is: the utility model is used for the water pipe screw connection mechanism of the water purifier, which includes a container body with an external thread and a container cover with an internal thread. The internal thread is screwed together and fixed together, wherein the port of the container body is provided with a buckle or/and a boss, and the port of the container cover is provided with a boss or/and a design that matches the buckle provided on the port of the container body. There is a buckle matched with the boss provided on the port of the container body.

The utility model adopts the buckle or/and boss on the port of the container body, and the port of the container cover is provided with a boss matching the buckle provided on the port of the container body or/and is provided with the boss of the container body. The structure of the buckle matched with the boss provided on the port, therefore, the cooperation between the buckle and the boss can prevent the relative rotation of the container body and the container cover due to the instantaneous hydraulic or gas impact in the container, thereby preventing loosening. The utility model has the advantages of simple structure and convenient use, and solves the problem of high assembly process requirements in the prior art. The utility model is a simple in structure, convenient and practical water pipe screw connection mechanism for water purifiers. The utility model is particularly suitable for being used in the structural arrangement of pipeline type water purification equipment.

Detailed ways

Example 1:

The structure diagram of the present utility model is shown in Fig. 1, 2, and the utility model is used for the water pipe screw connection mechanism of water purifier, comprises container body 3 with external thread, container cover 1 with internal thread, container body 3 and The container cover 1 is screwed and fixed together by external threads and internal threads provided with each other, wherein the port of the container body 3 is provided with buckles or/and bosses, and the port of the container cover 1 is provided with the port of the container body 3. Some buckles match with the bosses or/and are provided with buckles that match the bosses provided on the port of the container body 3 . In this embodiment, a buckle 4 is provided on the port of the container body 3 , and a boss 5 matched with the buckle 4 is provided on the port of the container cover 1 . When the container cover 1 and the container body 3 are screwed together, the height of the boss 5 is small, which does not affect the screwing action of the container cover 1 and the container body 3. After the container body 3 and the container cover 1 are screwed together, the buckle 4 catches the boss Platform 5, as shown in Figures 3 and 4.

When the utility model is assembled, in order to improve the tightness between the container body 3 and the container cover 1, the sealing ring is placed on the contact surface between the upper part of the container body 3 and the container cover 1 and is arranged on the container body 3 or/and the container cover 1, the container body 3 and the container cover 1 are screwed and fixed together through the external threads and internal threads provided with each other. When working, when the water hammer or gas impacts F in the container body 3 instantaneously, as shown in Figure 5 As shown, the container cover 1 performs an instantaneous relative rotational movement relative to the container body 3, so that the buckle 4 collides with the boss 5 and absorbs the force of the instantaneous rotational movement of the container cover 1 relative to the container body 3, so that the container cover 1 is relatively opposite to the container body 3. The location does not change.

Example 2:

The structure of the utility model is the same as that of Embodiment 1, the difference is that the port of the above-mentioned container body 3 is provided with a boss, and the port of the container cover 1 is provided with a card matching with the boss provided on the port of the container body 3. buckle.

The working principle of the utility model is the same as that of embodiment 1.

Claims (1)

1. a water pipe that is used for water-purifying machine mechanism that spins, include and be with externally threaded container body (3), tapped container cover (1), container body (3) and container cover (1) spin by the outside screw that is provided with each other and internal thread and are fixed together, the port that it is characterized in that container body (3) is provided with buckle or/and boss, and the port of container cover (1) is provided with the boss that the buckle that is provided with container body (3) port matches or/and be provided with the buckle that the boss that is provided with container body (3) port matches.
