Abstract

The utility model relates to a telescopic and collapsible hard rope draw bar. a square steel pipe which is made into a rectangle is matched with an anti-damping big spring, a spring hook pin, a spring locking fork, an acoustic-optic warning device, etc. The length when in use is from 2 to 3 meters; the length when in carrying can be shortened by a half. Compared with the common soft rope steel cable or the hard rope draw bar with a fixed length at present in the society, the utility model has the advantages of convenient carrying, use and storage. The utility model can be arranged into the back cover box of the common sedan cars. The utility model which has the strong modifiability in use is applicable to the front and back draw rings or lifting hooks of various types of vehicles. The safety and reliability can reduce the operating requirements and relieve the mental load of drivers. The telescopic and collapsible hard rope draw bar can be a more ideal vehicular tool for all drivers.

Description

The hard rope draw bar of fold concertina-wise formula

The utility model relates to a kind of automobile fault in use and casts anchor, and the draw bar with multiple function that traction and vehicle need towage use is rescued on the road.

At present, the common vehicle failure time channel that casts anchor is rescued traction in the society, most soft rope steel rope or simple hard rope draw bars that reach regular length of making of using, cause thus carry when being inconvenient to use both dangerous, also damage the hand skin easily and produce contingency, the draw bar of regular length had not both had spring auto lock fork and had not had big spring safety damped device yet, as two cars traction hanging ring is not that same direction also just can't have been used before and after running into.

The purpose of this utility model provides a kind of multi-purpose vehicle(MPV) draw bar, it can not only be convenient to chaufeur and be carried at any time in compartment or the operator's compartment, and two sections of draw bars spring locking fork being arranged in use, front end has big spring safety damped device and 90 degree to turn to use and electronic acoustooptic alerting signal.

The purpose of this utility model is achieved in that in the intermediate fabrication of two shaping steel tubes than chain and spring self-locking and unlocking apparatus just for folding, advance in the big steel pipe just for telescopic two kinds of both little inserting of different size steel pipe, load onto the locking of spring return two of steel pipes and pitch the usefulness that the towing pin minimizing dealing impulsion minimizing noise that can pitch on the automobile also can play buffering slightly, the pipe link that connects 4 punchings of a root at two segment type steel, back segment dress safety damped big spring, it is exactly that 90 degree turn to that leading portion is pulled up a commentaries on classics face at the connection latch, and it can be suitable for the vehicle traction hanging ring of different model and the use of suspension hook.

Owing to adopt such scheme, the hard rope draw bar of fold concertina-wise formula carry and use aspect suitable changeability compare with soft rope steel rope or regular length draw bar, have than failure-free safety sound and light alarm employing electronic component, simple and practical.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the planar configuration figure of the collapsible hard rope draw bar of the utility model.

Among the figure 1) traction circle 2) spring locking fork 3) mobile riveting pin 4) stub 5) recoil spring

6) spring pin 7) folding hinge 8) electron luminescence basin 9) handle

Fig. 2 is the shape of collapsible draw bar when carrying.

Fig. 3 is the planar configuration figure of telescopic draw bar.

6) electronic horn 7) switch 8) tubule knock hole 9) handle 10) the bassoon knock hole

11) small tubes 12) big pipe

Fig. 4 is the planar configuration figure of telescopic draw bar.

In example shown in Figure 1, traction circle 1) spring locking fork 2) mobile riveting pin is combined into and prevents that coming off of automobile suspension hook from reducing impulsion and noise back and forth, stub 4) pulling up a pipe link commentaries on classics face both had been that 90 degree turn to use, can play buffer action when recoil spring 5) two cars run into brake in the starting in when traction and way, spring pin 6) folding locking is easy to carry, folding hinge 7) when using, traction under the spring tongue effect, makes two firm one that are connected of steel pipes energy, it is luminous to open the switch flicker when electron luminescence box 8) using, point out two car chaufeurs and pedestrian to take care handle 9) carry mobile usefulness.

In the embodiment shown in fig. 3, pull up stub 4) extract small tubes 11 out) change a face and go here and there into big pipe 12 again) and in both be that 90 degree turn to use, open switch 7) electronic horn 6) both sent warning signal prompting chaufeur and pedestrian take care.

Because the hard rope draw bar of fold concertina-wise formula manufacture craft is simple, with low cost, it is also convenient to carry, take care of, all set aside concerns in general small passenger car bonnet railway carriage or compartment, can advocate the driver's tool that should be equipped with as automobile, allow more automobile have drafting tool, the vehicle that casts anchor of et out of order just is easy in time lead from anchorage on the road so from now on, and this also can play certain positive role for ensureing the city traffic order.

Claims

1, the hard rope draw bar of a kind of fold concertina-wise formula selects for use square steel pipe to make oblong-shaped, uses 2 to 3 meters of length length when carrying can shorten nearly half automobile drawbar, it is characterized in that: make that to overlap tower bolt telescopic and hinge spring pin bonded assembly is collapsible.

2, the hard rope draw bar of fold concertina-wise formula according to claim 1 is characterized in that: the leading portion mounting spring hook device back segment mounting spring of traction two hanging ring connects the locking fork.

3, the hard rope draw bar of fold concertina-wise formula according to claim 1 is characterized in that: all there was pin-and-hole on pipe four limits in towing pin connected.
