Abstract
The utility model discloses the improvement invention of a portable motor vehicle connection retractor. The utility model has the main characteristics that the pipe wall of the inner pull pipe is provided with positioning holes (1); the pipe wall of the outer sleeve pipe (2) is provided with limiting holes (3) which are matched with the positioning holes (1); the limiting holes (3) and the positioning holes (1) are positioned by lock pins (4). Because the utility model uses a structure that a telescopic pull rod is arranged in the outer sleeve pipe, when traction operation is implemented, the pull rod is extended, when the operation is finished, the pull rod is retracted. Thus, the utility model has the advantages of simple structure, convenient use and carrying along with a vehicle. Because the utility model uses a hard connecting mode, traction distance and steering angle can be ensured not to be changed in a set range, and because the outer sleeve pipe is provided with a plurality of limiting holes, the length of the traction distance can be adjusted by the change of the positions of the limiting holes, and thus, the use is safe and reliable. The utility model can also be flexibly connected with a chain, so that the integrated mode of soft traction and hard traction can be realized. The utility model is used for pulling large vehicles, such as a freight car or a truck, etc., to meet that drivers can effective watch the skidding condition behind a failure vehicle.
Description
Technical field: what the utility model was related is a kind of being used for carrying out the bonded assembly device between the self-propelled vehicle of trailer and et out of order, particularly to be that a kind of portable automobile is hard connect or tractor that soft or hard is connected.
Background technology: existing traction to self-propelled vehicle has two kinds of methods.A kind of method is rope to be lain in draw and be pulled in the hook or bumper/spoiler of car; Another kind method is that the draw bar with fixed length is hung in traction and the trailed hook.Cable traction is for the traction that is flexible coupling, its weak point, is pulled the car rear-end collision for what prevent that the tractor truck brake from causing, by adopting the lengthening drawing length, limit less tractor truck speed per hour, because tractor truck length is long, influence traffic, cause traffic accident easily.Because limit less tractor truck starting speed per hour, tractive force is little, the traction effort; The traction of fixed length draw bar was drawn for hard the connection, and its weak point is that the fixed length draw bar is a stock, is not easy to carry with car.
Summary of the invention: in view of the existing problem of known technology, the technical matters that the utility model solved its objective is that in order to provide a kind of easy to carry reasonable in design, portable automobile safe and reliable during use connects tractor.In order to achieve the above object, the utility model is finished by following mode: this kind portable automobile connects tractor firmly, the interior trombone slide that has outer tube and can in outer tube, stretch, termination at described outer tube and interior trombone slide is provided with hauling hook, the tube wall that it is characterized in that described interior trombone slide is provided with knock hole, the tube wall of described outer tube is provided with the spacing hole that matches with knock hole, and described spacing hole and knock hole are located by lock pin.At least 2 of described spacing holes.Knock hole when knock hole when trombone slide is provided with the trombone slide elongation in described and pull bar shorten.Hauling hook and chain in described on the trombone slide are flexible coupling.The utility model is owing to adopt telescopic Tiebar structure is housed in outer tube, when implementing towage, pull bar elongation, operation at the end, the pull bar withdrawal, therefore simple in structure, use and carry with car all convenient; And owing to adopt hard connecting mode, can guarantee in setting range that hauling distance and steering angle are constant, and because a plurality of spacing holes are set on outer tube, position that can be by conversion spacing hole is with adjustment hauling distance length, and is safe in utilization, reliable.The utility model also can also be flexible coupling with chain, and the mode to realize that soft traction and hard traction combine is used for carts such as lorry or truck are drawn, to satisfy the situation that slides that chaufeur can actv. be seen the failed vehicle back.
Description of drawings: the utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment: accompanying drawing has been represented structure and the embodiment that this is practical, further describes the relevant details and the principle of work of embodiment below more in conjunction with the accompanying drawings.This kind portable automobile connects tractor, the interior trombone slide 5 that has outer tube 2 and can in outer tube 2, stretch, termination at described outer tube 2 and interior trombone slide 5 is provided with hauling hook 6,6`, the tube wall of trombone slide 5 is provided with knock hole 1 in described, the tube wall of described outer tube 2 is provided with three spacing holes 3 that match with knock hole 1, the quantity of this spacing hole 3 can be provided with voluntarily according to user's requirement, and described spacing hole 3 locatees by lock pin 4 with knock hole 1.Knock hole 1` when the knock hole 1 when trombone slide 5 is provided with the trombone slide elongation in described shortens with pull bar.In the time will using this tractor, as long as trombone slide 5 in pulling out, knock hole 1 spacing hole 3 usefulness the lock pins 4 by interior trombone slide 5 are located, just connect failed vehicle then and trailer can.The utility model also can also be flexible coupling with chain, to realize soft traction and the mode that hard traction combines, is used for carts such as lorry or truck or long vehicle are drawn, and can see the situation that slides of seeing below failed vehicle by actv. to satisfy chaufeur.The utility model is reasonable in design, and is safe in utilization, easy to carry, is the indispensable parts of user vehicle.
