The specific embodiment
Describe a specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.Should be understood that, below the described specific embodiment only be used for description and interpretation the utility model, be not limited to the utility model.
As shown in Figure 2, car puller hook of the present utility model comprises matrix 11 and the hook portion 12 that is formed at matrix 11 1 ends, and the other end of matrix 11 is connected with baffle plate 2, and the free end of this baffle plate 2 is biased on the inside face of described hook portion 12 by the elastic force of spring 3.In this technical scheme, can form the structure of a closure between baffle plate 2 and the hook portion 12, thereby can avoid the landing from this car puller hook of trailer rope, the reliability and the safety that have improved trailer.
The free end of baffle plate 2 is biased on the inside face of hook portion 12 by the elastic force of spring 3, so that the structure of the closure of formation can easily be opened between baffle plate 2 and the hook portion 12, so that the trailer rope is put into wherein.The free end of baffle plate 2 can touch any suitable position on hook portion 12 inside faces, as long as can form the structure of above-mentioned closure and make this closed structure easily to open.Preferably, as shown in Figure 2, the free end of this baffle plate 2 is biased on the inside face of end of described hook portion 12, is beneficial to the trailer rope and can puts into easily in the closing structure that baffle plate 2 and hook portion 12 form.Certainly, contact with the end of hook portion 12 size at position of the free end of baffle plate 2 should guarantee that the free end of baffle plate 2 can not cross the end of hook portion 12 easily and can't form the structure of described closure.
In said structure, the free end of baffle plate 2 is that the biasing force by spring 3 is biased on the inside face of hook portion 12 or on the inside face of the end of hook portion 12, area of contact is little, and under the normal circumstances, hook portion 12 contacts on same straight line with baffle plate 2.But in the trailer process, baffle plate 2 is subjected to the trailer rope (figure does not show) or the influence of other external force easily, thereby makes baffle plate 2 and hook portion 12 dislocation separately make the landing from car puller hook of trailer rope easily.For avoiding the generation of this situation, in above-mentioned car puller hook, preferably use such car puller hook, the free-ended width of baffle plate 2 is greater than the width of the end of hook portion 12 in this car puller hook.Like this, even the phenomenon of baffle plate 2 and hook portion 12 dislocation occurs, can guarantee that also baffle plate 2 still can be biased on the inside face of end of hook portion 12 within the specific limits, has further prevented the therefrom landing of trailer rope.
Referring to Fig. 3, as seen from the figure, hook portion 12 smoothly extends to matrix 11 gradually, and matrix 11 forms the shape of plate, and the bight of this matrix 11 is formed with knock hole 13.Car puller hook can be fixed on before the vehicle body of automobile by knock hole 13 or carry out trailer behind the vehicle body of other vehicles.Preferably, as shown in Figure 3, all be formed with knock hole 13 in four bights of this matrix 11, thereby matrix 11 can be securely fixed on the automobile.Again as shown in Figure 2, the thickness of knock hole 13 positions is greater than the thickness of other positions in the matrix 11 in the matrix 11, and this structure can make car puller hook be fixedly mounted on the automobile more.Between two knock holees 13 of matrix 11 1 ends, also be formed with two fixed orifices.The matrix 11 of this car puller hook and hook portion 12 can be to be formed by the precision casting technology manufacturing, to strengthen the tensile strength of car puller hook, the safety when further having strengthened trailer.
Referring to Fig. 2 and Fig. 4, car puller hook also comprises base 4 and bearing pin 5, and base 4 is fixed on the described matrix 11 by fastener 6, and described baffle plate 2 is connected on the described base 4 by described bearing pin 5, and described spring 3 is arranged between described baffle plate 2 and the described base 4.
Specifically, be provided with two perforates at an end of base 4, this perforate is identical with two fixed orifice diameters on the above-mentioned matrix 11, and the fixed orifice on perforate on the base 4 and the matrix 11 cooperates with fastener 6 simultaneously, and base 4 is fixed on the matrix 11.The other end at base 4 is arranged with two lugs with holes in parallel.The width of described baffle plate 2 and base 4 bonded assemblys one end is less than the distance between two lugs, and has through hole and groove at this end of baffle plate 2.The described spring 3 preferred torsion springs that use, the spring coil of torsion spring is arranged in the groove of baffle plate 2, and an end of torsion spring is resisted against on the described base 4, and the other end of torsion spring is resisted against on the described baffle plate 2.Described bearing pin 5 passes the lug of base 4, the through hole of baffle plate 2 and the spring coil of torsion spring successively, and torsion spring set is contained on the described bearing pin 5, and baffle plate 2 links together with base 4 the most at last.Above-mentioned connection mode can be done various deformation, is not limited thereto, and for example widens the width of baffle plate 2, makes it greater than the distance between two lugs on the base 4, and the groove of baffle plate 2 is enough big, in order to lug and the spring 3 that holds base 4, re-uses bearing pin 5 and connects.
When preparing to put into the trailer rope, the free end of baffle plate 2 is subjected to the external force extruding, and baffle plate 2 is around the rotation of spring 3 centers and away from hook portion 12, this moment spring 3 stored energys.After forming enough big space between hook portion 12 and the baffle plate 2, the trailer rope is put into this space.Remove externally applied forces, spring 3 releases energy, and baffle plate 2 is withdrawn on the inside face that initial position is biased in hook portion 12 once more.
In addition, the utility model also provides a kind of automobile, and wherein, this automobile comprises above-mentioned car puller hook.
Preferred implementation of the present utility model has below been described in conjunction with the accompanying drawings; but the utility model is not limited to the detail that shows in the described above and accompanying drawing; in technical conceive scope of the present utility model; can carry out multiple obvious modification and combination to the technical solution of the utility model, protection domain of the present utility model is defined by the claims.
