Abstract
The utility model discloses a linkage structure of an electric water heater, wherein the linkage structure comprises a tube body and an inner container. The linkage structure is characterized in that one end of the tube body is connected with a linkage end molding element; one end of a first embedding element is embedded on the linkage end molding element, and the other end of the first embedding element is of an external screw thread structure, and protrudes to the linkage end molding element; the inner container is provided with an opening; a second embedding element is fixedly installed at the opening of the inner container, and is provided with an internal screw thread structure; and the internal screw thread of the second embedding element adapts to the external screw thread of the first embedding element. The linkage structure of the electric water heater provided by the utility model has the advantages of good sealing property, high product quality and the like.
Description
Technical field:
The utility model relates to a kind of syndeton of electric heater, relates in particular to the inner bag of electric heater and the syndeton between the water inlet pipe and water outlet pipe.
Background technology:
At present, be used for the connector of electric heater, like water inlet pipe and outlet pipe; It in the connected mode of inner bag generally is: inner bag adopts external thread structure, and water inlet pipe and water outlet pipe all adopts female thread structure; The defective that this structure mainly exists is: because inner bag adopts external thread structure; This external thread structure generally is flush-mounted on the inner bag through copper insert, when welding, can splash on the external screw thread owing to the booty that welding produces; Can not tightening seal thereby cause between inner bag and the water inlet pipe and water outlet pipe, thus cause leaking.
Have based on this, the applicant makes the utility model.
The utility model content:
The utility model purpose provides a kind of syndeton that can effectively improve the electric heater of sealing property between inner bag and the water inlet pipe and water outlet pipe.
The technical scheme that the utility model is taked is following: a kind of syndeton of electric heater, comprise body, inner bag, and it is characterized in that: an end of body is connected with the link plastic; First inserts, one end is flush-mounted on the link plastic, and the first inserts other end is an external thread structure, protrudes from the link plastic; Inner bag is provided with opening; The opening part of inner bag is fixed with second inserts, and second inserts has female thread structure, and the external screw thread of the internal thread of second inserts and first inserts is suitable.
Further:
Described body is water inlet pipe or outlet pipe.
Described first inserts, second inserts are copper insert or plastics inserts.
The beneficial effect of the utility model:
The utility model is set to external thread structure through the copper insert on the body; Copper insert on the inner bag is set to female thread structure; Thereby when preventing effectively to weld because of inner bag, the booty that welding produces splashes on the screw thread of copper insert, adopts the syndeton of the utility model; Have more excellent sealing ability, product quality improves greatly.
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.
Description of drawings:
Fig. 1 is the structural representation of the utility model body;
Fig. 2 is the structural representation of the utility model inner bag.
The specific embodiment:
Like Fig. 1, shown in Figure 2, the syndeton of a kind of electric heater of the utility model comprises body 1, inner bag 2, and body 1 can be water inlet pipe; Also can be outlet pipe, in the present embodiment, body 1 is the plastic tube of hollow; One end of body 1 is connected with link plastic 4, the first copper inserts 3 one ends and is flush-mounted on the link plastic 4, and first copper insert, 3 other ends are external thread structure; Protrude from link plastic 4, in the present embodiment, first copper insert 3 is injection molded into link plastic 4 and is wholely set.Inner bag 2 is provided with opening 6, and opening 6 places of inner bag 2 are fixed with second copper insert, 5, the second copper inserts 5 and have female thread structure, and the external screw thread of the internal thread of second copper insert 5 and first copper insert 3 is suitable.
The principle of the utility model is following: the utility model is set to external thread structure through the copper insert on the body; Copper insert on the inner bag is set to female thread structure; Thereby when preventing effectively to weld because of inner bag, the booty that welding produces splashes on the screw thread of copper insert, adopts the syndeton of the utility model; Have more excellent sealing ability, product quality improves greatly.
