Detailed Description

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which the invention belongs. The use of "first," "second," and similar terms in the description herein do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and components may be omitted.

As shown in fig. 1, the disclosed embodiment of the present invention discloses a joint assembly of an electric water heater, which comprises: the joint body 10, the elastic sleeve 20, the nut 30, the packing 40, and the gasket 50.

The joint body 10 is inserted into a cylinder wall 100 of the electric water heater, the cylinder wall 100 is the cylinder wall 100 at the end of the electric water heater, and the cylinder wall 100 is detachably plugged at the end of the electric water heater. The head of the joint body 10 is formed with a stop table 11, a section of the tail of the joint body 10 is formed with an external thread 12, the joint body 10 penetrates through a through hole 101 of the cylinder wall 100 (when the joint body 10 penetrates through the cylinder wall 100, the cylinder wall 100 is in a state of being detached from the electric water heater), the stop table 11 is used for stopping the inner side of the cylinder wall 100, and the sealing ring 40 is arranged between the stop table 11 and the cylinder wall 100 to play a certain sealing role.

The elastic sleeve 20, such as a rubber sleeve, is sleeved on the joint body 10 and is located between the joint body 10 and the through hole 101, and the outer end of the elastic sleeve 20 protrudes out of the cylinder wall 100.

The gasket 50 and the nut 30 are both sleeved on the joint body 10, the nut 30 and the external thread 12 form a threaded connection, the nut 30 is screwed to push the nut 30 against the elastic sleeve 20 by the gasket 50, after the elastic sleeve 20 is pushed against, the axial dimension of the elastic sleeve 20 becomes smaller or has a tendency of being forced to become smaller, and in order to maintain the volume unchanged, the outer diameter of the elastic sleeve 20 is increased or has a tendency of being forced to increase, and the inner diameter of the elastic sleeve 20 becomes smaller or has a tendency of being forced to decrease, so that the elastic sleeve 20 and the hole wall of the through hole 101 form a tight contact, and the elastic sleeve 20 and the joint body 10 form a tight contact, thereby achieving a better sealing effect between the joint body 10 and the cylinder wall 100.

The advantages of the above embodiment are:

the utility model discloses a nut 30 pushes away to elasticity external member 20 and makes and connect body 10 and section of thick bamboo wall 100 to realize sealing, and elasticity external member 20 can frequently dismantle in-process used repeatedly at connecting body 10, and can form in close contact with connecting body 10 with through-hole 101 because of elasticity external member 20, therefore sealed effect is better.
