Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of traction devices, in particular to a cargo tractor. Background Art
[0002] A cargo tractor is a device used to tow a flatbed trailer and the cargo on the flatbed trailer. When the cargo tractors currently on the market are connected to the flatbed trailer, the flatbed trailer needs to rely on a bolt assembly to connect to the cargo tractor. When the flatbed trailer needs to be detached from the cargo tractor, the bolt assembly used to connect the flatbed trailer and the cargo tractor needs to be removed, that is, there is a disadvantage of inconvenience in connecting and detaching the flatbed trailer and the cargo tractor. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a cargo tractor which has the advantage of being convenient to connect with and disconnect from a flatbed trailer.
[0004] The utility model provides a cargo tractor, comprising a tractor body, and the cargo tractor also comprises a latch; a standing area for a human body is arranged in the middle of the tractor body, two connecting plates which are spaced apart from each other are fixed to the bottom of the rear side of the tractor body, a gap is formed between the two connecting plates for a connecting ring on a flatbed trailer to be horizontally inserted; the lower end of the latch is vertically inserted in the two connecting plates, an annular convex edge is arranged on the outer peripheral wall of the latch, the annular convex edge is abutted against the upper end surface of the connecting plate located above, and the latch is also used for vertically penetrating into the connecting ring on the flatbed trailer located between the two connecting plates.
[0005] After the utility model adopts the above structure, the connecting ring on the flatbed trailer and the two connecting plates on the tractor body are connected together by means of the plug-in combination of the bolt. After the bolt is plugged into the connecting plate and the connecting ring on the flatbed trailer, the flatbed trailer can be connected to the tractor body. After the bolt is pulled out, the flatbed trailer can be separated from the tractor body, that is, it has the advantage of convenient connection and separation between the flatbed trailer and the cargo tractor. In addition, since an annular convex edge is provided on the outer peripheral wall of the bolt, the annular convex edge abuts against the upper end surface of the connecting plate located above, so that after the bolt is plugged in with the connecting plate and the connecting ring on the flatbed trailer, the bolt can be limited, and the upper end of the bolt can be exposed outside the connecting plate located above, and then when it is necessary to pull out the bolt, the staff can grasp the bolt exposed outside the connecting plate located above, which can facilitate the removal of the bolt and the separation of the flatbed trailer from the tractor body.
[0006] In one possible embodiment, a horizontal section is provided at the upper end of the latch, and the horizontal section is formed by bending the upper end of the latch. By providing the horizontal section at the upper end of the latch, when the latch needs to be pulled out from the connecting plate and the connecting ring on the flatbed trailer, the horizontal section can be abutted against the fingers to facilitate the staff to pull out the latch. In addition, since the horizontal section is formed by bending the upper end of the latch, that is, the horizontal section and the latch are integrally formed, the horizontal section and the latch have the advantage of high connection strength.
[0007] In one possible embodiment, an annular chamfered surface is provided on the outer peripheral wall of the lower end of the pin, and the annular chamfered surface is used to cooperate and guide with the inner hole on the connecting plate and the inner wall of the connecting ring on the flatbed trailer so as to facilitate the insertion of the lower end of the pin into the connecting plate and the connecting ring on the flatbed trailer; after the annular chamfered surface is provided on the outer peripheral wall of the lower end of the pin, when the pin is cooperated and plugged with the connecting plate and the connecting ring on the flatbed trailer, the annular chamfered surface can cooperate and guide with the inner hole on the connecting plate and the inner wall of the connecting ring on the flatbed trailer so as to facilitate the insertion of the lower end of the pin into the connecting plate and the connecting ring on the flatbed trailer, that is, it can bring convenience to the cooperation and plugging of the pin with the connecting plate and the connecting ring on the flatbed trailer.
[0008] In a possible implementation, a non-slip foot pad is attached to the inner bottom of the standing area; by attaching the non-slip foot pad to the inner bottom of the standing area, when the staff stands on the standing area, the friction between the feet and the inner bottom of the standing area can be increased, thereby achieving the purpose of anti-slip.
[0009] In a possible implementation, the rear side wall of the standing area gradually tilts backward from bottom to top; by adopting this structure, when the staff stands on the standing area and when the staff's hips and waist lean against the rear side wall of the standing area, the comfort of the staff can be improved.
[0010] In a possible embodiment, a lumbar support made of a flexible material is fixed to the upper portion of the rear side wall of the standing area; by fixing the lumbar support made of a flexible material to the upper portion of the rear side wall of the standing area, when the worker's waist rests on the lumbar support, the comfort of the worker's waist can be improved.
[0011] In a possible implementation, an alarm light is fixed to the upper part of the rear side of the tractor body, and the alarm light is electrically connected to a controller in the cargo tractor; through the setting of the alarm light, when the tractor body is running, the alarm light can flash, thereby alerting people around, thereby playing a warning role and effectively eliminating safety hazards.
