Description

Technical Field

[0001] The utility model relates to the technical field of electrical testing equipment, and more specifically, to an electrical load testing box. Background Art

[0002] A load test box (abbreviated as load box) is a power supply detection device, which is mainly used to perform load detection and maintenance on generators, uninterruptible power supplies (UPS), and power transmission equipment. Its use avoids economic losses caused by failure to start a standby unit or power supply, and also provides a scientific basis for the detection of the load capacity of a new unit. However, during the use of the existing electrical load test box, only the connector of the conductive wire of the power transmission equipment is plugged into the power connection port of the load box for electrical testing. Since the connector of the conductive wire cannot be limited and fixed, the connector of the conductive wire is easily detached from the power connection port when it is accidentally pulled, resulting in an interruption of the electrical test. In view of this, we propose an electrical load test box. Utility Model Content

[0019] like Figures 1 to 4 As shown, the utility model provides an electrical load test box, including a box body 1, a load device 101 is fixedly arranged inside the box body 1, and a plurality of power connection ports 2 are fixedly arranged at intervals on the side of the load device 101, and the power connection ports 2 run through the side of the box body 1, so as to facilitate plugging the connector 901 of the conductive wire 9 into the power connection port 2 for power-on testing, a circular frame 3 is fixedly installed on the side wall of the box body 1, a guide column 4 is fixedly installed inside the circular frame 3, two limit seats 5 are symmetrically slidably sleeved on the guide column 4, and a plurality of clamping block components 6 are spaced apart on the relative surfaces of the two limit seats 5, the circular frame 3 is rotatably connected to a bidirectional stud 7 through a connecting seat 301, and the two limit seats 5 are respectively threadedly sleeved on the upper and lower sides of the bidirectional stud 7, and the top of the circular frame 3 is movably sleeved on the outside of the bidirectional stud 7, and a knob block 701 is fixedly installed on the upper end of the bidirectional stud 7.

[0020] The clamping block component 6 includes a connecting block 601 and a positioning clamping block 602. The connecting block 601 is fixedly installed between the limiting seat 5 and the positioning clamping block 602. A groove 603 is provided on the surface of the positioning clamping block 602. The groove 603 is a component made of rubber, so that the positioning clamping block 602 has good anti-slip performance.

[0021] Among them, the upper surface of the bidirectional stud 7 is provided with a positive thread, and the lower surface of the bidirectional stud 7 is provided with a negative thread. The thread principles of the positive thread and the negative thread are opposite, so that when the bidirectional stud 7 rotates, it can drive the two limit seats 5 to move closer to or away from each other.

When the connector 901 needs to be pulled out, the knob block 701 is used to rotate the bidirectional stud 7 in the reverse direction, driving the two limit seats 5 to move away from each other along the guide column 4, so that the two positioning clamps 602 are synchronously separated from the connector 901 of the conductive wire 9, and the connector 901 plugged into the power connection port 2 can be pulled out.
