[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4This utility model discloses a mobile generator vehicle quick access device, comprising an outer access head 1, a protective layer 2 sleeved on the outside of the outer access head 1, a top block 3 fixed to the top of the outer access head 1, and an abutment component provided on the upper inner side of the outer access head 1. The abutment component includes an inner circular plate 4, a lead screw 5 rotating at the top center of the inner circular plate 4, a front gear 6 sleeved on the bottom outer side of the lead screw 5, a rear gear 7 meshing on the rear side of the front gear 6, a drive motor 8 fixed to the top of the rear gear 7, an impact tube 9 connected to the outside of the lead screw 5, the impact tube 9 penetrating to the top of the top block 3, and an abutment block 10 fixedly connected thereto. An external hole is opened on the outer positive end of the outer access head 1. In the prior art, this type of device for the access head of the generator vehicle, After use, it is hung in a designated position. This type of hanging requires repeated use, which wastes time and affects the efficiency of emergency power supply. Furthermore, long-term unstable connection may damage the generator and load equipment. To address this issue, an abutment component can be installed on the upper inner side of the outer access head 1. By inserting the outer power cord into the inner side of the snap-fit ​​protrusion 14, the drive motor 8 is started, which drives the rear gear 7 to rotate, thereby causing the front gear 6 to rotate. This causes the impact tube 9 to move upward along with the abutment block 10, and then the abutment block 10 is moved to the inner side of the snap-fit ​​protrusion 14 to abut the outer power cord, thus achieving the effect of fixing the power supply.

[0023] Multiple threaded inner grooves 11 are evenly provided on the bottom inner side of the outer layer connector body 1. An embedded block 12 is provided at the bottom of the outer layer connector body 1. Multiple threaded outer grooves 13 are evenly provided on the upper outer side of the embedded block 12. The embedded block 12 is threadedly connected to the bottom inner side of the outer layer connector body 1. The threaded outer grooves 13 on the outer side of the embedded block 12 facilitate its threaded connection to the bottom inner side of the outer layer connector body 1, thereby achieving the effect of replacing different lower power supply lines 15.

[0024] The top of the top block 3 is fixed with a snap-fit ​​protrusion 14. The inner end of the snap-fit ​​protrusion 14 is arc-shaped to facilitate snap-fit ​​of the outer power cord and reduce wear.

[0025] The inner side of the embedded block 12 is hollowed out, and the lower power supply line 15 is inserted into the inner side of the embedded block 12. This makes it easy to make the lower power supply line 15 perpendicular to the outer power line for convenient power supply. Both the impact tube 9 and the abutment block 10 are made smooth to avoid wear on the outer surface of the outer power line.

[0026] The protective layer 2 is circular in shape, which allows it to be better attached to the outer side of the outer access head 1. The front end of the outer side of the impact tube 9 is provided with a weight reduction groove 16, which is square in shape, to reduce the amount of raw materials used.

[0027] Working principle: First, the external power cord is inserted into the inner side of the snap-fit ​​protrusion 14 on the top of the outer layer of the head body 1. The arc-shaped inner end of the protrusion provides initial engagement, reducing friction and wear. Next, the drive motor 8 is started, driving the rear gear 7 to rotate. Through gear meshing, the front gear 6 rotates synchronously, which in turn drives the lead screw 5 to rotate. The rotation of the lead screw 5 causes the impact tube 9 to move axially upwards, pushing the abutment block 10 up to the inner side of the snap-fit ​​protrusion 14, applying a stable abutment force to the external power cord, achieving rapid fixation, avoiding repeated adjustments, and improving emergency power supply efficiency. Then, by rotating... Rotate the embedded block 12 so that its outer threaded groove 13 is separated from the inner threaded groove 11 at the bottom of the outer layer of the connector body 1. The embedded block 12 is detachable. Insert the matching lower power supply line 15 into the hollowed-out embedded block 12 and tighten the threaded connection again to realize the quick replacement of power supply lines of different specifications, ensuring vertical connection with the external power line and stable power supply. The weight reduction groove 16 of the impact tube 9 reduces the weight by square slotting, reducing material consumption. At the same time, the smooth surface of the impact tube 9 and the abutment block 10 avoids damage to the outer sheath of the power line, thereby improving operating efficiency.

[0028] The outer hole on the outer end of the outer access head 1 is used to fit the hook of the high-voltage link (insulated operating rod). This hole is usually designed to a standardized size, and the inner wall can be equipped with an anti-slip rubber bushing or a groove structure to enhance the engagement stability with the link hook. When an emergency power cut-off is required, the electrician inserts the hook of the high-voltage link into the outer hole of the outer access head 1, and rotates or pulls the link laterally, using the lever principle to rotate or displace the entire outer access head 1. If the outer access head 1 and the generator car interface are threaded, rotating the link can quickly loosen the interface; if it is a plug-in connection, pulling laterally can directly separate the connector, achieving rapid power cut-off. When working at heights or in confined spaces, the link hook can be fixed in the outer hole, and the access head 1 can be remotely guided to align with the power grid line, reducing... The circular design of the outer protective layer 2 prevents the link from slipping during operation, and the external hole position usually avoids live parts to ensure that the operation meets the safety distance requirements. For the drive motor 8, the start, stop and direction of the drive motor 8 can be directly controlled by a physical button or knob (such as a button shown on the drive motor 8 in the figure). It is suitable for emergency or debugging stages. A pressure sensor is embedded in the abutment block 10 to monitor the abutment force in real time. When the pressure reaches the set threshold (such as 50N), the motor will stop automatically to avoid overpressure damage to the power line. Alternatively, the number of rotations of the lead screw 5 can be detected by an encoder or Hall sensor to accurately control the stroke of the abutment block 10 and ensure that it rises to the preset position in the locking protrusion 14.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
