Technical Field

[0001] The utility model relates to the field of aircraft short-circuit testing, in particular to a portable short-circuit box. Background Art

[0002] The short circuit box is mainly used for aircraft short circuit testing. Portable and reliable test boxes are particularly popular with customers. The original models on the market are all portable boxes, which are bulky and inconvenient to move. Therefore, it is necessary to develop a short circuit test box that is flexible and easy to carry to meet the urgent needs of customers. Utility Model Content

[0003] The utility model aims to solve the problems existing in the background technology and to provide a portable short-circuit box with a telescopic pull rod, which is convenient to move and carry.

[0004] The technical solution of the utility model is a portable short-circuit box, which comprises a box body, running wheels and a pull rod; input copper bars and output copper bars are respectively arranged on both sides of the box body; the running wheels comprise two universal wheels arranged on the front side of the bottom of the box body and two directional wheels arranged on the rear side of the bottom of the box body; the pull rod is a telescopic structure, which is arranged at the bottom of the box body.

[0005] Preferably, the box body includes a main box, a sensor and a contactor arranged inside the main box, a terminal arranged on the side of the main box, an aviation plug and a self-locking button.

[0006] Preferably, cylindrical protective plates are provided on both sides of the main chassis, and the input copper busbar and the output copper busbar are respectively located on the inner sides of the two protective plates.

[0007] Preferably, a handle is provided on the side of the main chassis.

[0008] Preferably, a limited position anti-collision platform is provided on the directional wheel.

[0009] Compared with the prior art, the utility model has the following beneficial technical effects:

[0010] The utility model has a telescopic pull rod, which is convenient for movement and carrying. When used on site, the box can be fixed or moved arbitrarily by adjusting the lifting feet of the universal wheel. When carrying and moving, the pull rod hidden at the bottom can be pulled out and dragged to reduce the physical strength of the user. The pull rod can be flexibly adjusted in length according to the height of the user, and the applicability is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] like Figure 1-Figure 6 As shown, a portable short-circuit box proposed in this embodiment includes a box body, running wheels and a pull rod 2.

[0019] The box body includes a main box 1, a sensor 7 and a contactor 11 arranged inside the main box 1, a terminal 10 arranged on the side of the main box 1, an aviation plug 12 and a self-locking button 13. An input copper bar 5 and an output copper bar 9 are respectively arranged on both sides of the box body.

[0020] The running wheels include two universal wheels 3 arranged at the front side of the bottom of the box and two fixed wheels 4 arranged at the rear side of the bottom of the box. The universal wheels 3 have lifting feet that can fix or release the box. The fixed wheels 4 are provided with a limited anti-collision platform, which can prevent the fixed wheels 4 from being impacted by collision.

[0021] The pull rod 2 is a telescopic structure and is arranged at the bottom of the box body. The pull rod 2 includes a fixed cylinder portion arranged at the bottom of the main box 1 and a pull rod portion slidably arranged on the fixed cylinder portion, so that the pull rod 2 can be telescopically adjusted to adapt to the use of users of different heights.

[0022] Cylindrical protective plates 6 are provided on both sides of the main chassis 1. The input copper bar 5 and the output copper bar 9 are respectively located on the inner sides of the two protective plates 6, so that the input copper bar 5 and the output copper bar 9 are shielded and protected by the protective plates 6. The protective plates 6 are insulating plates.

[0023] A handle 8 is provided on the side of the main box 1, so that the whole box can be lifted conveniently.

[0024] This embodiment has a telescopic pull rod 2, which is convenient for movement and carrying. When used on site, the box can be fixed or moved arbitrarily by adjusting the lifting feet of the universal wheel 3. When carrying and moving, the pull rod 2 hidden at the bottom can be pulled out and dragged to reduce the physical strength of the user. The pulled-out length of the pull rod 2 can be flexibly adjusted according to the height of the user, and the applicability is good.

[0025] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
