Detailed Description

The present utility model will be described in further detail with reference to the following examples in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

As shown in fig. 1 and 2, the material combination combined trailer hook device provided by the embodiment of the utility model comprises a front trailer hook 2 and a rear trailer hook 3.

The front towing hook 2 and the rear towing hook 3 are respectively welded at the front end and the rear end of the material trolley 1.

As shown in fig. 3 and 4, the front towing hook 1 in the embodiment of the utility model is provided with a fixed groove part and a towing bar 204, and the towing bar 204 is matched and installed with the fixed groove part through a pin shaft 202 and a cotter pin 203;

the fixed groove piece is provided with a first groove piece 201 and a second groove piece 205, the first groove piece 201 and the second groove piece 205 are welded and combined, and the towing bar 204 is installed in the middle of the first groove piece 201 through the pin shaft 202.

The towing bar 204 is of a U-shaped bar structure, and a plurality of supporting cross bars are welded in the middle of the towing bar 204.

As shown in fig. 5 and 6, the rear towing hook 3 in the embodiment of the present utility model is provided with a groove-shaped member 303 and a pull rod 302, both the upper and lower ends of the groove-shaped member 303 are provided with bar-shaped holes, the pull rod 302 passes through the two bar-shaped holes, the upper end of the pull rod 302 is connected with the upper end of the groove-shaped member 303 through a rotating shaft 304, and a return spring is sleeved outside the rotating shaft 304. The upper end of the groove-shaped piece 303 is fixed with a shaft sleeve 301, and two ends of the rotating shaft 304 are fixed in a limiting way through the shaft sleeve 301.

The working principle of the utility model is as follows:

when the utility model is used, the towing bar 204 can freely rotate through the pin shaft 202, and when the utility model is not used, the towing bar 204 is rotated upwards to be in a vertical state, and when the utility model is used, the towing bar 204 is in a horizontal state. The pull rod 302 is matched with the shaft sleeve 301 after being welded with the rotating shaft 304, and the shaft sleeve 301 is welded with the groove-shaped piece 303; the end of the pull rod 302 exceeds the thickness of the groove-shaped member in a vertical state, the pull rod 302 can rotate up and down through the rotating shaft 304, the groove-shaped member 303 is provided with a strip-shaped hole up and down, and the rotating angle of the pull rod 302 is larger than 60 degrees in the up-and-down rotating process.
