Detailed Description
The present utility model will be described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1-6, the utility model provides a commercial vehicle trailer device, which comprises a trailer bracket 1 and a trailer pin 2, wherein the trailer bracket 1 is formed by welding a side plate 11, an upper arc casting 12 and a lower arc casting 13, the side plate 11 is of a square structure, four corners of the side plate are provided with mounting holes 14, and the side plate 11 is connected with the tail of a vehicle frame through bolts; the middle parts of the upper arc casting 12 and the lower arc casting 13 are provided with pin holes 15, and the trailer pin 2 is connected with the trailer bracket 1 through the pin holes 15 punched on the trailer bracket 1.
The upper arc casting 12 of the trailer bracket 1 is provided with a self-locking rod 5 through a bolt 3 and a nut 4, one end of the self-locking rod 5 is inserted into the trailer bracket 1 to be fixed, and the other end of the self-locking rod can elastically rotate.
The top of the trailer pin 2 is welded with a handle 21, a groove is arranged in the area of the trailer pin 2 below the handle 21, and when the self-locking rod 5 is clamped into the groove, the trailer pin 2 cannot be pulled out from the trailer bracket 1 (as shown in fig. 5); turning the trailer pin 2, the welding part of the handle 21 of the trailer pin 2 pushes the self-locking rod 5 to be separated from the groove, and simultaneously, the trailer pin is lifted upwards, and can be pulled out from the trailer bracket 1 (as shown in fig. 6); the structure facilitates the opening and closing of the trailer pin, and can effectively lock the trailer pin.
When the trailer is used, the trailer pin 2 is rotated firstly, the self-locking rod 5 is separated from the groove on the trailer pin 2, the trailer pin 2 is pulled out, then a trailer rope (or a trailer rod) is placed between the upper arc-shaped casting 12 and the lower arc-shaped casting 13, the trailer pin 2 is inserted into the pin hole 15, and the self-locking rod 5 is clamped into the groove on the trailer pin 2, so that self-locking is realized, and the trailer operation is performed; after the trailer is completed, the trailer pin 2 is rotated, so that the welding position of the handle 21 of the trailer pin 2 pushes the self-locking rod 5 to be separated from the groove, the trailer pin is lifted upwards, the trailer pin 2 is pulled out of the trailer bracket 1, the trailer rope (or the trailer rod) is detached, and then the trailer pin 2 is inserted into the pin hole 15, so that the whole trailer operation is completed.
The above-described embodiments of the utility model are intended to be examples only, and not to be limiting, and all changes that come within the scope of the utility model or equivalents thereto are intended to be embraced thereby.
