Hitch of the present invention comprises gib head, coupler body 4 and hook tail three parts, described gib head comprises hook tongue 5 and the lock iron 9 for locking bail tongue 5, and lower lock pin 7 and lifet lever 2, lock iron 9, lower lock pin 7 and lifet lever 2 is hinged successively, and lifet lever 2 is by rotating shaft 8 and coupler body 4 pivot joint; In addition, described hook head portions is formed with lower lock chamber, and lower lock pin 7 and little lock pin bar 2 are all built in lower lock chamber; When needing out hook, drive lifet lever 28 to rotate clockwise around the shaft, and then promote lower lock pin 7 and lock iron 9 to rise, to lock the locking face 51 that iron 9 leaves hook tongue 5, hook tongue 5 is in free state, and now applying external force to hook tongue 5 can open it.
Hitch of the present invention comprises anti-bouncing device, hook is driven to prevent the improper of hook tongue 5, described anti-bouncing device comprises elastic component 1, elastic component 1 is connected with lifet lever 2, when lifet lever 2 towards open hook direction move time, elastic component 1 can be acted on, make it produce elastic deformation, the elastic-restoring force of elastic component 1 can decompose the component producing and hinder lifet lever 2 movement, to prevent out hook.
Usually, can promote when lifet lever 2 moves lock iron 9 moves, and then hook tongue 5 to be discharged, that is, described in open the usual corresponding lifet lever 2 in hook direction on move.
The noun of locality such as described upper and lower, front and back is with hitch normal operating condition for reference herein, and when hitch normally uses, the direction towards ground or orbital plane is described below, and correspondingly, the direction away from ground or orbital plane is top; At the service direction of vehicle, be front near the direction of hook tongue 5, the direction away from hook tongue 5 is rear, i.e. the direction of hook tail.
As shown in Figure 6 and Figure 7, can stretch out in the both sides of lifet lever 2 and boss 21 is set, then connecting portion 21 is set on boss 21, to install elastic component 1 respectively in the both sides of lifet lever 2, if then lifet lever 2 moved, the elastic component 1 of its both sides all can produce elastic deformation, moves, and then effectively prevent out hook to hinder on it.
Because boss 21 is arranged on the both sides of lifet lever 2, can its space, both sides of Appropriate application, can not affect operating personal by the lift of coupling lever to lifet lever 2, what also would not hinder hitch normally opens hook operation.
The both sides of described lifet lever 2 for reference, refer to the both sides of the track centerline of vehicle operating with the travel direction of vehicle.
When elastic component 1 is arranged on the both sides of lifet lever 2, interference can not be produced to the miscellaneous part in lower lock chamber, while the anti-jump reliability of guarantee, the normal use of whole hitch can not be affected.
Elastic component 1 can be set to torsion spring, and now, torsion spring can be sleeved in rotating shaft 8, and as shown in Figure 5, one end of torsion spring is connected with lifet lever 2, when lifet lever 28 rotation around the shaft, drives torsion spring 8 to reverse generation distortion around the shaft, obstruction lifet lever 2 moves.
When torsion spring set is contained in rotating shaft 8, can the length of proper extension rotating shaft 8, so that rotating shaft 8 has certain axial space after running through lifet lever 2 with its two ends, the torsion spring suit for both sides is fixing, as shown in Figure 8.
Meanwhile, described connecting portion 211 specifically can be set to positioning groove, so that one of them torque arm grafting of torsion spring is positioned in this positioning groove, torsion spring can be driven to produce reverse when lifet lever 2 moves.
Below in conjunction with accompanying drawing, anti-bouncing device of the present invention is specifically described.
Be the birds-eye view of anti-bouncing device provided by the present invention in a kind of detailed description of the invention please further refer to Fig. 9 and Figure 10, Fig. 9; Figure 10 is the lateral plan of anti-bouncing device shown in Fig. 9.
In a kind of detailed description of the invention, elastic component 1 can be torsion spring, and described torsion spring has the first torque arm 11 and the second torque arm 12, first torque arm 11 is connected with the lower lock chamber wall 3 of hitch, and the second torque arm 12 is connected with lifet lever 2; When lifet lever 2 leaves hook relative to lower lock chamber wall 3 moves, then the first torque arm 11 and the second torque arm 12 turn-back, makes torque arm produce torsional deflection, applies antagonistic force by the second torque arm 12 to lifet lever 2, moves to hinder in its continuation.
First torque arm 11 of torsion spring locks the both sides in chamber under can being arranged on and being close to hitch, can be the stud part of lower lock chamber wall 3, so both can not affect the effect propety of hitch, also not affect the work of miscellaneous part beyond hitch, install and use comparatively simple, the space taken is also less.
In above-mentioned torsion spring structure, torsion spring servo-actuated required anglec of rotation when needing on the one hand to consider that hook normally left by hitch; On the other hand, need according in hitch use procedure, overcome that hitch is improper to be left the amount of force needed for hook and set operation torque needed for torsion spring.That is, the resistance against torsion of torsion spring, prick the setting of number etc., need the smooth torsion that simultaneously meets when normally driving hook and open pining down of hook to improper.
Because lower lock chamber wall 3 is in relative stationary state, then the first torque arm 11 is equivalent to an attachment point, and lifet lever 2 applies application force by the second torque arm 12 pairs of torsion springs; Assuming that the axial distance between the first torque arm 11 and the second torque arm 12 is L, when lifet lever 2 is subject to directed force F upwards, relative first torque arm 11 of second torque arm 12 is reversed, producing size is the moment of torsion of F × L, under the effect of this moment of torsion, torsion spring produces torsional deflection, and then applies to lifet lever 2 antagonistic force hindering its motion.
Those skilled in the art should expect, hitch can be vibrated in normal use procedure, this vibration can cause lifet lever 2 initiatively on move, the application force of elastic component 1 pair of lifet lever 2 should be enough to overcome vibratory force, according to above-mentioned action principle, distance L between first torque arm 11 and the second torque arm 12 can be rationally set, to increase moment of torsion, overcome vibrate cause lifet lever 2 on move.
Meanwhile, the length of the first torque arm 11 and the second torque arm 12 should be rationally set, if the long work that can affect lower lock chamber inner body of length, too short, likely cause torque arm throw off and do not have anti creep performance.
First torque arm 11 also can mutually vertically be arranged with the second torque arm 12, can take into account anti-jump reliability, also can not produce considerable influence to normally opening hook; And, when the first torque arm 11 is vertical with the second torque arm 12 arrange time, two torque arm can with lower lock chamber wall 3 and lifet lever 2 respectively grafting fix, be convenient to the installation realizing torsion spring.
In another detailed description of the invention, elastic component 1 can be set to elastic draw bar, and the two ends of elastic draw bar are connected with lower lock chamber wall 3 and lifet lever 2 respectively, then elastic draw bar is arranged between lower lock chamber wall 3 and lifet lever 2 naturally; Due to lifet lever 2 when hitch locks and the position relationship between lower lock chamber wall 3 relatively fixing, when driving hook when lifet lever 2 relatively lower lock chamber wall 3 moves, will inevitably extrude or stretch described elastic draw bar, then elastic draw bar can produce elastic-restoring force, this elastic-restoring force at least can decomposite the downward pulling force of lifet lever 2, thus obstruction lifet lever 2 moves on continuing, and prevents out hook.
In the third detailed description of the invention, elastic component 1 can also be elasticity extension spring, one end and the lifet lever 2 of described elasticity extension spring are connected, the lower lock chamber wall 3 of the other end and hitch is connected, when driving hook when lifet lever 2 relatively lower lock chamber wall 3 moves, described elasticity extension spring pulls lifet lever 2 downwards, hinders it to move towards opening hook direction.
It should be noted that, when elastic component 1 is set to elastic draw bar or elasticity extension spring, usually rely on the tensile deformation of elastic component 1 to carry out spacing to lifet lever 2; When elastic component 1 produces crimp along with lifet lever 2 moves, elastic component 1 usually adopts the less material of elasticity to make, in order to avoid the undue deformation of elastic component 1 and depart from the crush-zone of lifet lever 2 and lower lock chamber wall 3.
Obviously, elastic component 1 can also be set to other structures, and lower lock chamber wall 3 is only parts of geo-stationary when lifet lever 2 moves, therefore, every and lower lock chamber wall 3 keeps the structure of geo-stationary all can form the attachment point of elastic component 1, is not limited to lower lock chamber wall 3.
Anti-bouncing device of the present invention comprises the elastic component 1 be connected with lifet lever 2, even if hitch produces vibration or carries out overturning operation in the operational process of vehicle, due to the obstruction of elastic component 1, hitch still can keep lock-out state, avoids the improper of hitch to drive hook; When needs open hook operation to hitch, the coupling lever of the longer arm of force can being adopted to drive lifet lever 2 to move towards opening hook direction, to make hitch be in out hook-shaped state, larger obstruction can not be produced to opening normally hook.
Therefore, elastic component 1, regardless of when carrying out out hook or when hitch is in the lock state, all can be arranged on hitch, need not install or remove according to the handling situations of hitch, and its structure is simple, can take into account anti-jump reliability and the convenience of operation; Because elastic component 1 can adopt once mounting shaping, compared with the plug carrying out latch with the connecting end portion needed in prior art in compartment, its use is safer.
In addition, on above-mentioned anti-bouncing device basis, hitch of the present invention also arranges corresponding structure and carries out anti-jump on lower lock pin 7 and lifet lever 2.
Please refer to Figure 11-14, Figure 11 is the construction profile schematic diagram that in hitch of the present invention, lifet lever is in non-anti-jump position in a kind of detailed description of the invention; Figure 12 is in the construction profile schematic diagram of anti-jump position for lifet lever shown in Figure 11; Figure 13 is the construction profile schematic diagram that in hitch of the present invention, lower lock pin is in anti-jump position in one embodiment; Figure 14 is the birds-eye view of structure shown in Figure 13.
