Description

Technical field

The present invention relates to a power supply interface device, in particular to a power supply interface device having a shock absorption function.

State of the art

Power supply interface devices with shock absorption function are currently known. One of the devices is described in Chinese patent application CN 201210224018. Today's technology requires a reliable and convenient electrical connection between electrical equipment and power supply equipment. However, the existing power supply equipment does not guarantee the reliability and stability of power supply. Although the power supply equipment has achieved a reliable electrical connection, its automatic implementation cannot be achieved. More importantly, the connector to the socket and the insertion connector must be securely connected and then blocked when a mechanical construction connector cannot be guaranteed at the same time.

The essence of the invention

The object of the present invention is to provide a power supply interface device with shock absorption function. The device can overcome the above disadvantages.

According to the present invention, the power supply interface device with shock absorption function comprises a housing, an electrical outlet connector mounted on the lower side wall of the housing, and an electrical supply plug device mounted on the upper wall. The power outlet device includes the power cord and the power outlet used for the electrical connection to the electrical plug device. The power plug assembly includes two top-pressing bolt members fixedly connected to the top side wall of the housing. The two top-pressing bolt members are symmetrically mounted with respect to the longitudinal axis of the housing, and each includes a thread fixed coupling mounted on the top wall of the housing, a top-pressed screw secured with a threaded hole in the underside of the thread fixed coupling. below the threaded fixed coupling and is fixedly coupled to the top press bolt and the coupling member which is connected to the lower end of the top press bolt through the down thrust bearing. The coupling member is pivotally connected to an adjacent edge of the guide bar mounting plate via a pivotally connected shaft. The power guide bar is mounted on the underside of the guide bar mounting plate for electrical connection to the power hole. The engine lift and lower mounting platform is mounted in the housing and above the bolt drive. The rotary drive motor, which is connected to the gear, is mounted in the lower half of the engine lifting and lowering mounting platform in the middle and the left end and right end pass through a vertically sliding damper, respectively, two threaded elements in the threaded fixed coupling connected to the upper end of the respective pressurized bolt through the upward thrust bearing. The shock absorber cover (12) is located between the periphery of the rotary drive motor (6) and the mounting platform (62) for raising and lowering the engine. The shock absorber cover (12) is used to reduce the shaking force generated by the rotary drive motor (6) and improve its operational stability. The upper side of the engine lift and lower mounting platform is connected to the upper side wall of the housing via an elastic joint. The engine lift and lower mounting platform is slidably adjustable with a vertical sliding gutter in the thread fixed coupling plane to prevent rotation of the engine lift and lower attachment platform relative to the thread fixed coupling. The pinion engages two screw pinions at the same time. When the rotary drive motor drives two of the top pressing bolt elements to rotate the top pressing bolt, the top pressing bolt can move downward toward the thread fixed coupling and press the guide bar mounting plate at both ends. Thus, the guide rack mounting plate drives the power guide bar to move downward so that the power guide bar is gradually inserted into the power supply port so that the power guide bar and the power supply hole reach the electrical connection. When the rotating drive motor rotates in reverse, it can rotate the power guide rod to raise and disengage from disconnection with the power supply hole to disconnect the electrical connection between the power guide rod and the power supply hole.

In view of the above device, since two symmetrical top-tapping screws are used to press the guide bar mounting plate, deformation can be avoided when the power cord is inserted into the mains hole. It also ensures that the wire rod is securely inserted in the wire and improves the stability of the electrical connection. In addition, since the entire high-pressure actuator is in the middle and drives the overpressure bolts on both sides at the same time, the number of actuators decreases. Meanwhile, the power control rod can achieve position locking, while the power guide rod and power hole reach the electrical connector. When the electrical connection is required, the reverse drive of the rotary drive motor rotates the overpressure screw backwards to achieve disconnection between the power guide and the power outlet. Meanwhile, the power guide position lock can be released. Because the engine lift and lower mounting platform is connected to the upper side wall of the housing through an elastic portion, the load on the threaded opening can be partially or fully offset to avoid excess current. The structure of the whole device is stable. Easy to use. It can also effectively address gaps in existing technologies.

The power supply socket device (1) comprises an electrical power cord (3) and a power supply socket (2) used for electrical connection to the electrical plug device. The electrical plug device comprises two top-pressing bolt members (8) fixedly connected to the upper side wall of the housing (91). The two top-pressing bolt members (8) are symmetrically mounted with respect to the longitudinal axis of the housing (91) and each includes a threaded fixed sleeve (82) attached to the top wall of the housing (91), a top-pressing bolt (81). which is fixed to a threaded hole (821) on the underside of the thread fixed coupling (82), a helical gear (813) which is located below the thread fixed coupling (82) and is fixedly connected to the top-pressing bolt (81) and the coupling element (82). 88) which is connected to the lower end of a top-pressure screw (81) through a downward thrust bearing (811). The coupling member (88) is pivotally connected to an adjacent edge of the guide bar mounting plate (72) via a pivotally connected shaft (87). The power guide bar (4) is mounted on the underside of the guide bar mounting plate (72) for electrical connection to the power supply hole (2). The engine lifting and lowering mounting platform (62) is mounted in the housing (91) and above the bolt drive (813). The rotary drive motor (6) coupled to the gear (61) is mounted in the middle of the lower half of the engine lifting and lowering mounting platform (62) and passes through a vertically sliding damper (820), two upper pressed elements (8). 8) respectively threaded in the threaded locking sleeve (82) to the respective threaded fixed sleeve (82) and is connected to the upper end of the respective pressurized screw (81) through the upward thrust bearing (812). The shock absorber cover (12) is located between the periphery of the rotary drive motor (6) and the mounting platform (62) for raising and lowering the engine. The shock absorber cover (12) is used to reduce the shaking force generated by the rotary drive motor (6) and improve its operational stability. The upper side of the engine lifting and lowering mounting platform (62) is connected to the upper side wall of the housing (91) via an elastic coupling (629). The engine lifting and lowering mounting platform (62) is slidably adapted with a vertical sliding gutter (820) in the plane of the threaded fixed coupling (82) so as to prevent rotation of the engine lifting and lowering mounting platform (62) relative to the threaded fixed coupling (82). . The pinion gear (61) engages the two bolt pinions (813) at the same time. When the rotary drive motor (6) drives two of the top pressing bolt members (8) to rotate the top pressing bolt (81), the top pressing bolt (81) can move downward towards the thread fixed coupling (82) and press the guide bar mounting plate (82). 72) from both ends. Thus, the guide rack mounting plate (72) drives the power guide bar (4) to move downward so that the power guide bar (4) is gradually inserted into the power supply hole (2), so that the power guide bar (4) and the power supply hole (2) ) reaches the electrical connection. When the rotary drive motor (6) rotates in reverse, it can rotate the power guide bar (4) to raise and disengage from disconnection with the power supply hole (2) to make the electrical connection between the power guide bar (4) and the power supply hole (2). ) would be disconnected.

Optionally or simply, the elastic fitting (629) is an expansion spring.

Optionally or typically, the depth of the power supply hole (2) is slightly less than the length of the power guide rod (4).

In view of the above device, since two symmetrical top-tapping screws are used to press the guide bar mounting plate, deformation can be avoided when the power cord is inserted into the mains hole. It also ensures that the power cord is securely inserted in the power cord and improves the stability of the electrical connection. Because the entire high pressure actuator is in the middle and drives the top pressure screws on both sides at the same time, the amount of actuator elements is reduced. Meanwhile, the power control rod can achieve position locking, and the power guide rod and power supply hole reach the electrical connector. When the electrical connection is required, the reverse drive of the rotary drive motor rotates the overpressure screw backwards to achieve disconnection between the electrical guide and the power supply hole. Meanwhile, the positioning of the electric guide can be released. Because the engine lift and lower mounting platform is connected to the top side wall of the housing via an elastic portion, the load on the threaded hole can be partially or fully offset to avoid excess current. The structure of the whole device is stable. Easy to use. It can also effectively address gaps in existing technologies.
