Abstract

The utility model relates to a plug trip protection device for an electric vehicle, which comprises a socket arranged on the vehicle; a bracket is rotatably connected on the socket; a limiting block is arranged on the bracket; and the bracket can move the limiting block to a locking place above the socket and can also move the limiting block to a to-be-locked place at the side face of the socket. Since the plug trip protection device is provided with the bracket which is rotatably arranged on the socket and the limiting block is arranged on the bracket, before the plug is plugged into the socket, the bracket can be rotated to the to-be-locked place and can not affect the normal plugging-in and out of the plug; and when the plug is plugged into the socket, the bracket can be rotated to the locking place to enable the limiting block on the bracket to be positioned at the rear head face of the plug. In this way, the plug can be fixed on the socket and can not disengage. The plug trip protection device is unique and reasonable in design; the bracket is made of a metal round rod through bending and is convenient to make and convenient and simple to install; and the limiting block is rotatably arranged on the bracket and is provided with a positioning face, a transitional face and a circular arc face, and is convenient to operate and can be locked firmly, thereby having great practicability.

Description

Electric motor car plug locking device

Technical field

The utility model relates to a kind of electric motor car and is electrically connected accessory, particularly a kind of electric motor car plug locking device.

Background technology

Along with improving constantly of people's energy-conserving and environment-protective consciousness, electric motor car is more and more used by popular.The electric motor car storage battery mostly cooperates by being connected between the plug and socket with the electrical connection of vehicle body realizes that promptly vehicle body is provided with socket, and storage battery is inserted into plug in the socket during connection by electric wire attachment plug, guarantees that the motor of vehicle body runs well.Yet electric motor car produces because of pavement roughness through regular meeting in the process of travelling and jolts; this jolting usually can cause plug to get loose; thereby cause electric motor car in the process of moving power supply instability in addition the outage phenomenon, bring inconvenience to the user, even may cause traffic accident.

The utility model content

The purpose of this utility model is to provide a kind of electric motor car plug locking device of guaranteeing that plug can not get loose.

The technical scheme that realizes the utility model purpose is: the utlity model has the socket that is arranged on the vehicle body, be rotatably connected to support on the socket, guide vane end stop is rotationally connected on the support.

The support of above-mentioned electric motor car plug locking device is the rectangle that metal round rod bends the lower openings that forms, and the two ends of its opening are rotatably connected on the socket both sides, and guide vane end stop is rotationally connected on the cross bar of top.

The guide vane end stop of above-mentioned electric motor car plug locking device has locating surface and transition face.

Has arc surface between the locating surface of the guide vane end stop of above-mentioned electric motor car plug locking device and the mistake corrugated.

The utlity model has following characteristics: (1) the utlity model has and rotates the support that is arranged on the socket, support is provided with guide vane end stop, before plug did not insert socket, support can rotate to position to be locked, did not influence the normal plug of plug, after plug insertion socket, rotatable support makes that the guide vane end stop on the support is positioned at the plug rear end face, thereby plug is fixed on the socket to latched position, can not get loose, reasonable in design ingenious; (2) support employing metal round rod of the present utility model bends and forms, and is easily manufactured, simple installation; (3) guide vane end stop of the present utility model rotates and is arranged on the support, has locating surface, transition face and arc surface, and is easy to operate, and locking firmly has advantages of high practicability.

Description of drawings

For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the utility model supporting structure schematic diagram;

Fig. 3 is the utility model guide vane end stop structural representation.

Embodiment

(embodiment 1)

See Fig. 1 to Fig. 3, the utlity model has the socket 1 that is arranged on the vehicle body; Be rotatably connected to support 2 on the socket 1, the rectangle of the lower openings that described support 2 forms for metal round rod bends, the two ends 21 of its opening are rotatably connected on socket 1 both sides, and guide vane end stop 3 is rotationally connected on the cross bar 22 of top; Described guide vane end stop 3 has locating surface 31 and transition face 32, has arc surface 33 between locating surface 31 and the transition face 32; Support 2 can move to guide vane end stop 3 latched position of socket 1 top, also guide vane end stop 3 can be moved to the position to be locked of socket 1 side.

Earlier support 2 is turned to position to be locked during use, then plug 4 is inserted socket 1, swinging mounting 2 is to the latched position of socket 1 top, this moment, the cross bar 22 of support 2 was positioned at the plug rear end, end in contact behind the transition face 32 of guide vane end stop 3 and the plug, rotary spacing piece 3, make its locating surface 31 inconsistent, thereby the locking plug prevent that it from getting loose with the plug rear end, owing to have arc surface 33 between the transition face 32 of guide vane end stop 3 and the locating surface 31, so rotary spacing piece 30 minutes easily, and after conflicting with locating surface 31 and plug rear end, pull as no manpower, can not break away from, so anti-loose function is very solid and reliable.
