In order to achieve the above object, the technical solution of the utility model: a kind of self dumping lorory back door jack latch hook, comprise and the hinged latch hook body of fixed support plate being welded on bottom plate of dump truck horizontal bar, described latch hook body comprises two blocks of parallel side plates, each side plate all has the tilted plate section that the straight plate section on top and bottom and this straight plate section are obliquely installed, the free end of described tilted plate section is semicircular arc, straight plate pars infrasegmentalis position in the angle of inclination in straight plate section and tilted plate section place has shoulder, and this shoulder and tilted plate section arc transition arrange; Free end correspondence at biside plate is established the first pin shaft hole, in this first pin shaft hole, is installed with axle sleeve, in the shoulder correspondence of biside plate, establishes the second pin shaft hole; Described biside plate is fixed on one by the several gussets between it.
Further, described gusset and biside plate welding are connected.
Further concrete, described gusset includes: be positioned at straight plate section top and the front gusset for the face of self dumping lorory back door jack locking positioning is close to; The large gusset being close in the shoulder opposite face of straight plate section, this large gusset upper end and front gusset against, its lower end extends on tilted plate section; Small gusset on tilted plate section, this small gusset is adjacent to the face at described tilted plate section and straight plate section formation leaning angle place.
Further, institute's gusset outer face to the distance between its contiguous latch hook body side is 5mm.
Further, described axle sleeve both ends of the surface indent is in the outer face 3mm of biside plate distance.
Further, between described axle sleeve and the first pin shaft hole, interference fit is connected.
During use, by the axle sleeve in the self dumping lorory back door jack latch hook in the utility model and be welded between the fixed support plate on bottom plate of dump truck horizontal bar and fix by pin hinge, make the angle of inclination at straight plate section and tilted plate section place towards body of tipper carriage, and the thickness direction of biside plate is vertical with the direction of latch hook coupling mechanism force; Again by setting up bearing pin at the second pin shaft hole, by setting up lifting chain to be connected on the pulling seat on the chassis of dumping car on this bearing pin, locking lifting chain.
The beneficial effects of the utility model: rational in infrastructure, intensity is reliable, and locking is tight, and alleviated weight, good looking appearance, the problem of effectively having eliminated latch hook distortion and having leaked material.

Fig. 1 is that master of the present utility model looks schematic diagram;
Fig. 2 is that schematic diagram is looked on a left side of Fig. 1;
Fig. 3 is use view of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing, further describe the utility model.
A kind of self dumping lorory back door jack latch hook as Figure 1-3, it comprises and the hinged latch hook body 10 of fixed support plate 11 being welded on bottom plate of dump truck horizontal bar, described latch hook body 10 comprises two blocks of parallel side plates 1, each side plate 1 all has the tilted plate section 102 that the straight plate section 101 on top and bottom and this straight plate section 101 are obliquely installed, the free end of described tilted plate section 102 is semicircular arc, straight plate pars infrasegmentalis position in the angle of inclination in straight plate section 101 and tilted plate section 102 places has shoulder 103, this shoulder 103 and tilted plate section 102 arc transition settings; In the free end correspondence of biside plate 1, establish the first pin shaft hole 6, in this first pin shaft hole 6, be installed with axle sleeve 2, in shoulder 103 correspondences of biside plate 1, establish the second pin shaft hole 7; Described biside plate 1 is fixed on one by the several gussets between it.
Biside plate 1 in the utility model is fitfull J-shaped shape structure, the axle sleeve 2 of its lower end is installed on the fixed support plate 11 being welded on bottom plate of dump truck horizontal bar by pin hinge, for fear of axle sleeve 2 and fixed support plate 11, interfere or rub and cause wearing and tearing, in the outer face 3mm of biside plate 1 distance, make increase the service life of this axle sleeve 2 described axle sleeve 2 both ends of the surface indents; In addition, avoid in the course of the work, axle sleeve 2 slides in the first pin shaft hole 6, interference fit between described axle sleeve 2 and the first pin shaft hole 6 is connected, also in order indirectly to avoid axle sleeve 2 to be worn and torn, reduce service life, in use, can the lubricating oils such as butter be set betwixt and be lubricated.And described the second pin shaft hole 7 is for bearing pin is set, and on bearing pin, assemble lifting chain 12 to the pulling seat 13 on the chassis of dumping car, lifting chain 12 adopts slip-knot bolt to carry out adjustable locking in pulling seat 13.
For biside plate 1, achieve a fixed connection and play the gusset of reinforced rib effect, it includes: be positioned at straight plate section 101 tops and the front gusset 3 for the face of self dumping lorory back door jack locking positioning is close to; The large gusset 4 that shoulder 103 opposite faces in straight plate section 101 are close to, these large gusset 4 upper ends and front gusset 3 against, its lower end extends on tilted plate section 102; Small gusset 5 on tilted plate section 102, this small gusset 5 is adjacent to described tilted plate section 102 and straight plate section 101 and forms the face at leaning angle place, through test, after this type of set-up mode, the intensity of self dumping lorory back door jack latch hook own has obtained greatly improving, and material is saved, cost is low, and certainly, such arranges is only the preferred embodiment in the utility model, in practice, also can adopt other gusset setting position.In the present embodiment, described gusset is all connected with biside plate 1 welding, and institute's gusset outer face to the distance between its contiguous latch hook body 10 sides is 5mm, certainly, in practice, the connection mode of this gusset and biside plate 1 also can adopt other mechanical connection, and such as riveted joint etc., and institute's gusset outer face to the distance between its contiguous latch hook body 10 sides also can be determined as the case may be.
