Technical Field

[0001] The utility model belongs to the field of lighting disaster relief equipment, in particular to a towing chassis and mobile lighting equipment. Background Art

[0002] For emergency lighting equipment, a trailer chassis is usually set up to be connected to a tractor for towing. In addition to wheels, the existing trailer chassis is also provided with telescopic legs, so that when the trailer chassis is parked, the telescopic legs can touch the ground to improve the parking stability of the trailer chassis. However, the spacing of the telescopic legs on the existing trailer chassis is not adjustable. When the width of the chassis body is relatively narrow and the lamp pole is high, there is a risk of rollover. In addition, when the telescopic legs are vertically arranged on the chassis body, it will also affect the passing performance of the trailer chassis during towing. Utility Model Content

[0003] In order to solve the above technical problems, one of the purposes of the utility model is to provide a trailer chassis with a simple structure and good supporting performance in the parking state.

[0004] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows: a towing chassis, comprising a width adjustment member, a chassis body and three support legs, the chassis body is arranged along the front and rear directions, and wheels are arranged at the rear ends of both sides thereof, a towing rod is protruding forwardly at the middle part of the front end of the chassis body, a hanging ring is arranged at the end of the front end of the towing rod, and a support leg is arranged at the middle part corresponding to the length direction of the towing rod, the width adjustment member is installed at the front end of the chassis body, the support leg located on the towing rod is the auxiliary support leg, and the remaining two support legs are main support legs, and the two main support legs are arranged on both sides of the front end of the chassis body and connected to the width adjustment member, and the width adjustment member is used to adjust the distance between the two main support legs.
