Embodiment Construction
[0012] The following describes the technical solution of the present invention in detail through a best embodiment in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the embodiment.
[0013] Such as figure 1 As shown, a double-spherical towing buckle for a pump truck includes two male buckles 1 with ball heads 11 hinged to each other and two female buckles 2 respectively fitted with concave spherical surfaces 21, one of which is a male buckle A rectangular slot 12 is provided, and the other male buckle is provided with a rectangular handle 13 matched with the rectangular slot 12, the rectangular slot 12 and the rectangular handle 13 are hinged by a pin 3, and the male buckle is made of spring steel. The double-spherical towing buckle of the pump truck, the ball head of the male buckle cooperates with the concave spherical surface, realizes 360-degree torsion and realizes free return in the horizontal and vertical ...

The invention discloses a double-spherical-surface trailer coupler of a pump truck. The double-spherical-surface trailer coupler of the pump truck comprises two male couplers (1) and two female couplers (2), wherein the two male couplers (1) are mutually hinged and are respectively provided with a ball head (11), and the two female couplers (2) are respectively matched with the two male couplers (1) and are respectively provided with a concave spherical surface (21). By adopting the technical scheme, the double-spherical-surface trailer coupler of the pump truck has the advantages that since the two ends are matched through the ball heads and concave spherical surfaces and are respectively connected with a pump truck frame and a trailer pump, the effects of horizontal and vertical free gyration and 360-degree free torsion are realized; and since the two male couplers are hinged, a buffering effect is realized, the structure is more reasonable, the wear is reduced and the service life of the double-spherical-surface trailer coupler of the pump truck is improved.
Description
technical field [0001] The invention relates to a pump truck accessory, in particular to a pump truck double-spherical tow hook. Background technique [0002] The connection between the pump support pump and the frame of the pump truck needs to use the pump truck trailer buckle. The tow buckle of the pump truck in the prior art only has free rotation in the horizontal and vertical directions, and it is easy to cause damage to the tow buckle of the pump truck when it is twisted when walking on an uneven road surface, and it is severely worn during use and has a short life. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to address the deficiencies of the prior art and provide a pump truck double-spherical tow hook with reasonable structure, free return in the horizontal and vertical directions, and free 360-degree twist. [0004] Technical solution: In order to realize the above-mentioned purpose of the invention, the technical ...
