Description

Technical Field

[0001] The present application relates to the technical field of telescopic sockets, and more specifically, to a telescopic socket. Background Art

[0002] With the development of society, there are a large number of various household appliances around us. Due to the increasing number of household appliances, sockets have become an indispensable daily necessity in our daily life.

[0024] 3. Beneficial effects

[0025] One or more technical solutions provided in the technical solution of this application have at least the following technical effects or advantages:

[0026] 1. When in use, the present application can drive the active piston to move downward by rotating the power screw, so that the active piston continuously injects hydraulic oil from the liquid storage column cavity into the matching column cavity, and then the auxiliary slave piston continuously pushes the socket body out of the inner cavity of the socket tube cover under the drive of the hydraulic pressure, so that the socket has a telescopic function, occupies less space, and is convenient for people to carry.

[0027] 2. When the present application is not in use, after the socket body is retracted into the inner cavity of the socket cover, the moisture-proof door panel covering the top opening of the inner cavity of the socket cover can be used to provide moisture-proof protection for the socket body retracted into the inner cavity of the socket cover, thereby preventing moisture in the environment from contacting the socket body and causing leakage or short circuit, thereby improving the safety of the socket.

[0028] 3. When the moisture-proof door panel is covered on the top opening of the inner cavity of the socket tube cover, the sealing ring can be pressed tightly against the inside of the sealing ring groove due to the magnetic attraction between the upper magnet block and the lower magnet block. This not only further improves the fixing effect of the moisture-proof door panel, but also further improves the moisture-proof sealing effect of the device.

[0029] 4. When the moisture-proof door panel is closed, the moisture in the air in the inner cavity of the socket tube cover enters the interior of the receiving tube through the air holes at the bottom of the moisture-proof door panel and comes into contact with the desiccant particle layer. The desiccant particle layer then absorbs the moisture in the air, thereby reducing the humidity in the environment where the socket body is idle, thereby further improving the moisture-proof protection effect of the socket body.

[0030] 5. After the container is screwed off from the threaded groove on the moisture-proof door panel, it is convenient for people to regularly replace the desiccant particle layer. BRIEF DESCRIPTION OF THE DRAWINGS
