Abstract

The utility model provides a metal USB socket for railcar, its characterized in that: open a socket on socket shell body surface, socket shell body socket department extends the interior cavity that establishes of shell, and socket and cavity department can reciprocating motion's elastic mechanism when establishing a plug USB plug, the utility model discloses a but the elastic mechanism of reciprocating motion is constituteed jointly to the spring in the push pedal of socket department and the casing cavity for when extracting the USB plug, the push pedal can seal the socket under the effect of spring and realize waterproof function. Compare current USB socket and more adapt to rail vehicle's technical requirement, structural strength is higher, satisfies the impact vibration requirement, satisfies requirements such as waterproof, fire prevention, prevent portrayal, and to passenger's security height.

Description

Metal USB socket for subway vehicle

Technical Field

The utility model belongs to the technical field of rail vehicle installs internally, especially, relate to a make things convenient for metal USB socket of passenger's usefulness of charging.

Background

Current USB socket generally adopts the plastics material in the present railway vehicle carriage, and is unable waterproof, and structural strength is low, and can't satisfy the higher fire prevention requirement of railway vehicle, appears easily by the portrayal, damage scheduling problem.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a USB socket of metal material has waterproof scheme, and structural strength is high, can satisfy the higher fire prevention requirement of railway vehicle, and is difficult to take place the ruling and damage scheduling problem.

In order to realize the above-mentioned utility model purpose, the utility model provides a metal USB socket for railcar, its characterized in that: the surface of the socket shell is provided with a socket, a cavity is arranged in the extension shell of the socket shell, and an elastic mechanism which can reciprocate when a USB plug is plugged and pulled is arranged at the socket and the cavity.

Preferably, the elastic mechanism is that a limiting block is arranged at the cavity, a spring is arranged in the limiting block, a sealing plate is arranged at the socket, and the sealing plate is matched with the spring to realize resilience and seal the socket, so that a waterproof effect is realized.

Preferably, the limiting block is of a U-shaped structure with two unequal sides, so that the spring can be prevented from dislocating, and the structural strength is improved.

Preferably, the sealing plate protrudes out of the socket at one side of the socket end to form an upright push plate, the part in the cavity is a bending pressing plate, and the bending pressing plate extends into the spring to compress the spring.

Preferably, the part of the push plate, which is positioned in the socket, is straight, and the part, which protrudes out of the socket, is bent towards the opening direction, so that a passenger can push the push plate to use the USB socket conveniently, and the bent plate protruding out of the socket is ensured to be small in size, and the passenger and other objects cannot be scratched or bruised.

The utility model discloses a but the spring in the push pedal of socket department and the casing cavity constitutes reciprocating motion's elastic mechanism jointly for when extracting the USB plug, the push pedal can seal the socket under the effect of spring and realize waterproof function. Compare current USB socket and more adapt to rail vehicle's technical requirement, structural strength is higher, satisfies the impact vibration requirement, satisfies requirements such as waterproof, fire prevention, prevent portrayal, and to passenger's security height.

Detailed Description

Referring to fig. 1 and 2, a metal USB socket for a subway vehicle is characterized in that: the surface of the socket shell 1 is provided with a socket 2, a cavity is arranged in the extension shell at the socket of the socket shell, and an elastic mechanism which can reciprocate when a USB plug is plugged and pulled is arranged at the socket and the cavity.

Elastic mechanism establish a stopper 3 in cavity department, be equipped with spring 4 in the stopper, a shrouding is established to socket department, the shrouding realizes kick-backing with the spring cooperation and seals the socket, realizes waterproof effect. The limiting block is of a U-shaped structure with two unequal sides, so that the spring can be prevented from dislocating, and the structural strength is improved.

Referring to fig. 3, the shrouding is including the clamp plate 5 of bending, shrouding body 6, push pedal 7, and clamp plate 5 and push pedal 7 of bending establish at the both ends of shrouding body 6, and push pedal 7 is a riser, is located socket end one side protrusion in socket, and clamp plate 5 of bending stretches into compression spring in the cavity inner spring 4. The part of the push plate 7, which is positioned in the socket, is straight, and the part which protrudes out of the socket is bent towards the opening direction, so that a passenger can push the push plate to use the USB socket conveniently, the bent plate which protrudes out of the socket is ensured to be small in size, and the passenger and other objects cannot be scratched or bruised.
