Abstract

The utility model relates to a car towing rod, which relates to a car towing tool. The utility model is characterized in that a car towing rod is provided with a sleeve tube, both ends of the sleeve tube are respectively connected with draw rods, and the tail ends of two draw rods are provided with adjustable anti-collision blocks. The connecting points of the sleeve tube and the draw rods and the tail ends of the draw rods are provided with lock fasteners, and the tail parts of screw rods of the lock fasteners are provided with spring pins. The utility model has the advantages of convenient installation and disassembly and safe operation, and a single piece can be used as a driver tool.

Description

The car drawbar

The utility model relates to a kind of car and tows instrument.

At present, when car or jeep break down, typically using soft traction (ropes such as steel rope, brown numb nylon) finishes and tows, the disadvantage that this type of flexible ropes traction exists is: forward and backward car driver spirit high-pressure, especially in the winter time on the road surface that accumulated snow ice is sliding or on the smooth road surface of water in other in season, and when towing on the road surface, acclive mountain area, back car driver will note observing the degree of tightness of front truck afterbody and rope constantly, at any time to note preparing brake in order to avoid the front and back car collides, too short as used rope, then very easily cause forward and backward car collision; Long as rope, then mix pedestrian or the vehicle of not noting rope and laterally passing by on one's way easily, cause personal injury or traffic accident.In addition, when using cable traction, be traveling on some narrow road section and can not move backward, retreat; Two cars can not tow fast on fair running road surface; Under the situation of failed vehicle brake system failure, then can not adopt flexible ropes to draw, draw and travel; When night running, there is not the distinguishing mark caution down, also cause traffic accident easily.

The purpose of this utility model provides and a kind ofly installs and removes conveniently, safe and reliable multi-functional car drawbar, to overcome the defective that prior art exists.

The technical solution of the utility model is: a sleeve pipe is set, and the two ends of sleeve pipe connect a pull bar respectively, the anti-collision block of end configuration of two pull bars, and the junction of sleeve pipe and pull bar and the end of pull bar are provided with snap close, and the snap close screw rod tail is provided with spring pin.Sleeve pipe is to be made by a solid drawn pipe, two ends radially are provided with through hole, the surface scribbles the noctilucence film, pull bar also is to be made by solid drawn pipe, the two ends of pull bar radially are provided with through hole, be plugged with bearing pin near the at both ends lead to the hole site and steel pipe is integrally welded, and solid flat chisel that extends into of pull bar head end, different is that flat chisel changes drill rod into to another pull bar, many one is that benchmark revolves the through hole that turn 90 degrees with former radial direction through hole in addition, and the end of two pull bars is axially arranged with tapped bore, and anti-collision block is adjustable, one end is a screw thread, and the other end is the spill arc surface.

Good effect of the present utility model is as follows:

1. after two cars articulated drawbar, distance can be maintained fixed, and can be advanced, turn to, move backward with front truck by trailer, does not turn to the dead angle;

2. under the situation malfunctioning, can keep the traction of spacing to travel by trailer brake system;

3. improve greatly and tow efficient, on good highway, tow, the time scooter more than hundred kilometers;

4. there is one deck luminescent film on car drawbar intermediate casing surface, and night, the lamp photograph was reflective, served as warning, and has improved to tow safety factor night;

5. the pull bar in the car drawbar can be used as the use of single-piece instrument.

Below in conjunction with accompanying drawing the utility model is described in detail:

Fig. 1 is a general assembly drawing of the present utility model;

Fig. 2 is the structural representation of anti-collision block of the present utility model.

As shown in Figure 1, sleeve pipe 4 is made by a solid drawn pipe, two ends radially are provided with through hole, the surface scribbles the noctilucence film, the sleeve pipe two ends respectively with pull bar 2, the head end of pull bar 6 connects, two pull bars also are to be made by solid drawn pipe, the two ends of pull bar radially are provided with through hole, in order to improve the tensile strength of drawbar, be plugged with bearing pin near the at both ends lead to the hole site and steel pipe is integrally welded, and pull bar 2 the solid extension of head end forge into flat chisel 7, pull bar 6 is that flat chisel 7 is changed into drill rod 8 with the difference of pull bar 2, many one is that benchmark revolves the through hole 9 that turn 90 degrees with former radial direction through hole outward in addition, so that the configuration difference of various car draw rings, do parallel or perpendicular to the ground adjustment, the end of two pull bars is axially arranged with tapped bore, two pull bars also can be done emergent use of driver's tool (as crowbar etc.).The junction of sleeve pipe and pull bar and the end of pull bar are provided with snap close 3, snap close 3 screw rod tails are by spring pin 5 location, with slip-off preventing, terminal snap close is used to connect traction car and the draw ring that is pulled on the car, for dwindle as far as possible snap close with before, the joint gap of back car draw ring, prevent near the finish paint that the scratching draw ring is, avoid producing in the process of towing and collide, the anti-collision block 1 of configuration in two pull bar end thread holes, as shown in Figure 2, anti-collision block is adjustable, and an end is a screw thread, is used to connect the end of two pull bars, the other end is the spill arc surface, in order to contact with the car draw ring is slick and sly, and the gap of adjusting between anti-collision block and draw ring by the screw thread that rotates anti-collision block reaches minimum, and this adjustable anti-collision block is applicable to homemade, car and jeeps such as import.
