Abstract

The invention discloses a roller type water spray prevention socket, and relates to the technical field of power sockets. According to the attached drawings, the power socket openings (2) and (5) are blocked by the rollers (7), (10) and (14), (16) which are tightly contacted and made of flexible materials, and water cannot enter the power socket openings. When the pins (1), (4) of a national standard plug enter the sockets (2), (5), the rollers (7), (10) and (14), (16) rotate along the shafts (9), (11) and (15), (18) until the pins are fully inserted. When the pins (1) and (4) are completely pulled out, the rollers (7), (10) and (14), (16) are restored to the original state. Thereby realizing the function of preventing water spraying of the socket. When only a single object is inserted into the jack, the ratchet wheel braking system works, the friction force between the rollers at the jack is increased, and the single object is difficult to enter the socket, so that the safety door is realized.

Description

Roller type water spray prevention socket

Technical Field

The invention relates to the technical field of power sockets.

Background

The socket port of the common power socket is open and does not have the waterproof function. If water enters the socket, the socket may be accidentally leaked. Generally, a waterproof cover is additionally arranged to prevent water from entering the socket. Although the socket has a certain function of preventing water spray, the socket opening is still in an open state, so that potential safety hazards still exist.

Disclosure of Invention

In order to solve the waterproof problem of the power socket opening, the invention installs two rollers made of flexible materials on each socket opening, and no gap is left between the rollers and the socket, so that water flow can not enter the socket from the socket. When the international pins are plugged, the rollers rotate along with the pins, so that the abrasion of the metal pins to the rollers is very small, and the service life of the rollers is prolonged. Compared with the prior art, the invention better solves the problem of water spray prevention of the socket opening. The invention is also provided with a safety door device, which has certain protection function for preventing single-pin misplug, especially for children.

Description of the drawings:

the invention is further illustrated by the following figures and examples. The attached drawing is a schematic diagram of the relevant device. Fig. 1 shows the state after the national standard plug is inserted, and fig. 2 shows the state when a single object is used to enter the jack.

The specific implementation method comprises the following steps:

when the pins (1), (4) of the national standard plug are inserted, two rollers (7), (10) and (14), (16) which are tightly contacted with each other are respectively arranged below the sockets (2), (5) and rotate along the shafts (9), (11) and (15), (18) along with the pins (1), (4). After the pins (1) and (4) are completely inserted, water can not enter the socket through the sockets due to the extrusion of the flexible materials of the rollers on the pins (1) and (4). When the pins (1) and (4) are inserted, the driven wheel (12) is acted by the upward same-direction force of the rollers (10) and (14), and the shaft (13) moves upward along the shaft hole of the bracket (3), so that the friction on the rollers (10) and (14) is reduced. When the plug is pulled out, the rollers (7), (10), (14) and (16) are restored to the original state, so that the waterproof function of the socket is realized. When the pin is pulled out, the driven wheel (12) is acted by the downward same-direction force of the rollers (10) and (14) to return to the original position. For preventing the misplug of a single foot, as shown in fig. 2, when an object (1) enters through the jack (2), the roller (10) transmits the friction force to the rollers (14) and (16) through the driven wheel (12), and the driven wheel (12) cannot rise due to the unilateral downward acting force. When the roller (16) is stressed, the coaxial ratchet wheel (17) is driven to rotate reversely along the shaft (18) and is braked by the stop sheet (19), the rollers (16) and (14) and the driven wheel (12) stop rotating, the braking force is transmitted to the roller (10), and friction force is generated to prevent an object (1) from entering. Similarly, if the socket (5) is inserted by a single foot of an object, the ratchet wheel (8) is braked by the stop piece (6), and after the force is transmitted, the roller (14) stops rotating to generate friction force to prevent the object from entering.

Claims

1. The utility model provides a power socket mouth prevent water drenching device which characterized in that uses flexible material preparation can the pivoted gyro wheel, carries out the shutoff to the socket mouth.

2. The device as claimed in claim 1, wherein the internal ratchet means provides a braking force against the inserted object when the receptacle is inserted through a single opening.
