Abstract

The invention belongs to vehicle dragging tool, it is comprised by front rod, back rod and connection rod. Wherein connecter which is connected with dragging vehicle and dragged vehicle is arranged in both front rod and back rod, the said connecter is impact hook or clamp hook. Impact hook includes up and lower two pieces fixed clamps and moveable clamps which are connected by hinge shaft, when moveable clamp's opening lock is at position pillar, it is open state. When it is at reposition handle, it is close state. Clamp hook includes duck-billed hook handle and two moveable clamps which connected in the duck through hinge shaft, it is comprised ball and socket in the back of the two moveable clamps, it is comprised locking mechanism. It includes lock valve and reposition handle, it is close state when bearing lock in both ends of lock valve is at moveable clamp's ball and socket, it is opening state when bearing is leaving clamp's ball and socket. The invention realize inflexible connection between dragging vehicle and dragged vehicle, it is easy for use and safe and reliable.

Description

Assembling automobile drawbar

Technical field:

The invention belongs to a kind of vehicle traction apparatus.

Background technology:

In the prior art, traditional vehicle traction apparatus be with steel rope or similarly rope with tractor truck be pulled car and link together.This mode is simple, but exists hidden danger, especially when meeting the bump of back car to front truck takes place easily when descending traction or tractor truck touch on the brake.Chinese patent CN2194286Y discloses a kind of " vehicle traction apparatus ", it improves traditional rope class apparatus, mainly be to replace rope with traction belt, not only fundamentally do not change the soft connectivity problem between two cars, and the self-locking type that it adopted or lantern ring type adaptor union also exist poor stability and awkward defective.

Summary of the invention:

Task of the present invention is at the problems referred to above, and a kind of assembling automobile drawbar is provided, and it not only can realize tractor truck and rigid connection that is pulled between the car, and easy to use, safe and reliable.

One of its technical solution is: a kind of assembling automobile drawbar, form by preceding bar, back bar and middle brace rod, wherein be respectively equipped with on the bar in preceding bar and back with tractor truck be pulled the adaptor union that car is connected, said adaptor union is the impacting type hook, it is characterized in that: said impacting type hook comprises with two regular jaws up and down of neck of hook one with by a slice moving jaw in the middle of the hinge bonded assembly, wherein moving jaw has two states, being opening when its gap is stuck in registration mast, is closure state when its gap is stuck in when resetting handle.

Two of its technical solution is: a kind of assembling automobile drawbar, by preceding bar, back bar and middle brace rod are formed, wherein be respectively equipped with on the bar in preceding bar and back with tractor truck be pulled the adaptor union that car is connected, said adaptor union is jaw formula hook, it is characterized in that: said jaw formula hook comprises that duck chews the formula neck of hook and is connected in two moving jaws that duck chews the centre by hinge, rear portion at two moving jaws is provided with ball-and-socket, inside and outside chewing, the duck of corresponding ball-and-socket is provided with catch gear, said catch gear comprises being positioned at the detent valve that duck chews and being positioned at duck chews outer reseting handle, its two ends of said detent valve are provided with bearing by built-in spring, it has two states, when the bearing at its two ends is stuck in the ball-and-socket of moving jaw is closure state, is opening when the bearing at its two ends leaves the ball-and-socket of moving jaw.

Compared with prior art, the present invention be rod with bar be connected with tractor truck be pulled car and be linked together the accident generation that just can avoid back car and front truck to bump against thus.Especially adaptor union provided by the invention is not only easy to use, and safe and reliable.Wherein the hook of implementing according to technical scheme one as long as tractor truck one is exerted oneself a little, can be pulled locked by hooks on the hook circle of car, and after finishing towage, need not to use much power, and moving reseting handle can be with opening of hook.Wherein the hook of implementing according to technical scheme two as long as two moving jaws are aimed at the hook circle that is pulled car, is moved reseting handle and the hook circle firmly can be pinned, if again reversing sense move reseting handle can be with opening of hook.The present invention is simple in structure, and is easy to carry, and often the phase is not placed in the car boot time spent.

Description of drawings:

Fig. 1 is a structural representation of the present invention.

Fig. 2, Fig. 3 are the hook structure scheme drawings of implementing according to technical scheme one.

Fig. 4, Fig. 5, Fig. 6 are the hook structure scheme drawings of implementing according to technical scheme two.

The specific embodiment:

Below in conjunction with accompanying drawing the present invention is elaborated.

As shown in Figure 1, assembling automobile drawbar provided by the invention, forms by preceding bar, back bar and middle brace rod, wherein on preceding bar and back bar, be respectively equipped with tractor truck be pulled the adaptor union that car is connected, said adaptor union is that impacting type or jaw formula are linked up with.And the adaptor union here adopts rotary type to be connected with preceding bar or back bar, and promptly adaptor union can rotate 360 °, changes with the different directions that adapts to different vehicle hook circle.

As Fig. 2, shown in Figure 3, impacting type provided by the invention hook comprises with two regular jaws 3 up and down of the neck of hook 1 one with by a slice moving jaw 4 in the middle of hinge 5 bonded assemblys, wherein moving jaw 4 has two states, as shown in Figure 2, is opening when its gap is stuck in registration mast 6; As shown in Figure 3, be closure state when its gap is stuck in when resetting handle 2.

As Fig. 4, Fig. 5, shown in Figure 6, jaw formula hook provided by the invention, comprise that duck chews the formula neck of hook 12 and is connected in two moving jaws 13 that duck chews the centre by hinge 16, wherein be provided with ball-and-socket, inside and outside the duck of corresponding ball-and-socket chews, be provided with catch gear at the rear portion of two moving jaws 13.Here said catch gear comprises being positioned at the detent valve 15 that duck chews and being positioned at duck chews outer reseting handle 11, said detent valve 15 its two ends are provided with bearing 14 by built-in spring, it has two states, as shown in Figure 5, when the bearing 14 at its two ends is stuck in the ball-and-socket of moving jaw 13, be closure state; As shown in Figure 6, when the bearing at its two ends leaves the ball-and-socket of moving jaw 13, be opening.

The present invention mainly is applicable to the traction of dilly.

Claims

1, a kind of assembling automobile drawbar, by preceding bar, back bar and middle brace rod are formed, wherein be respectively equipped with on the bar in preceding bar and back with tractor truck be pulled the adaptor union that car is connected, said adaptor union is the impacting type hook, it is characterized in that: said impacting type hook comprises with two regular jaws (3) up and down of the neck of hook (1) one with by a slice moving jaw (4) in the middle of hinge (5) bonded assembly, wherein moving jaw (4) has two states, being opening when its gap is stuck in registration mast (6), is closure state when its gap is stuck in the handle that resets (2).
