Description
Technical field:
The present invention relates to a kind of Telescoping trailers mechanism, it belongs to Trailer tool field.
Background technology:
Driver and conductor or vehicle ambulance paramedic, when vehicle et out of order, often can use a trailer rope that vehicle is drawn to repair plant, and existing trailer rope is generally changed a social system by strap, steel wire or nylon rope to form, and length has and is easy to carry.
Existing trailer rope is in the engineering of trailer, and one end of trailer rope is fixed on the chassis of vehicle, and trailer rope is through after front bumper simultaneously, by pulling trailer rope, and then pulls fault car.Then, by this kind of mode when pulling vehicle, because trailer rope is arranged in front bumper, therefore in the process pulling trailer rope, trailer rope can rock in a different direction, make so constantly to rub between trailer rope and front bumper, therefore can bring infringement to front bumper.
Therefore, necessary the deficiency solving prior art is improved to prior art.
Summary of the invention:
The object of the present invention is to provide a kind of Telescoping trailers mechanism safe and reliable, easy to use.
The present invention adopts following technical scheme: a kind of Telescoping trailers mechanism, it comprises Telescoping trailers hook assembly, bolt and the vehicle frame be bolted above Telescoping trailers hook assembly, described Telescoping trailers hook assembly comprises casing, to be installed in casing and the slide block that can horizontally slip along the inwall of casing, rectangular tube together with being welded in slide block, be arranged at the trailer rope in rectangular tube and trailer rope be fixed on unhook latch that is in rectangular tube and that be positioned at outside casing, described casing is hollow form structure, one sidewall is provided with the perforate of passing for rectangular tube, the outward flange of described slide block is close on the inwall of casing, between described casing and slide block, be provided with one can the flexible pull back spring of horizontal direction, one end of described pull back spring is connected on casing, another end is connected on slide block, the side that described casing is positioned at slide block is provided with the seam block being close to casing front and rear wall, described seam block and pull back spring are positioned at the same side of slide block, described seam block is positioned at the below of pull back spring.
Further, described pull back spring and rectangular tube lay respectively at the left and right sides of slide block.
Further, described trailer rope is sheathed on described unhook latch.
The present invention has following beneficial effect: Telescoping trailers mechanism of the present invention when in use; trailer rope is positioned at the outside of front bumper completely; like this in the process of trailer, trailer rope all can not collide with front bumper and rub, and well plays effect of protection front bumper.
Accompanying drawing illustrates:
Fig. 1 is the cutaway view of Telescoping trailers mechanism of the present invention when pull back spring initial condition.
Fig. 2 is the cutaway view of Telescoping trailers mechanism of the present invention when pull back spring extended state.
Wherein:
1-Telescoping trailers hook assembly; 2-bolt; 3-casing; 4-slide block; 5-rectangular tube; 6-vehicle frame; 7-unhook latch; 8-pull back spring; 9-seam block;
Detailed description of the invention:
Please refer to shown in Fig. 1 and Fig. 2, Telescoping trailers mechanism of the present invention comprises Telescoping trailers hook assembly 1 and is connected to the vehicle frame 6 above Telescoping trailers hook assembly 1 by bolt 2.Wherein Telescoping trailers hook assembly 1 comprise casing 3, be installed in casing 3 and the slide block 4 that can horizontally slip along the inwall of casing 3, to be welded in slide block 4 together with rectangular tube 5, be arranged at the trailer rope (not shown) in rectangular tube 5 and trailer rope be fixed on unhook latch 7 that is in rectangular tube 5 and that be positioned at outside casing 3.Wherein casing 3 is hollow form structure, and one sidewall is provided with the perforate (sign) of passing for rectangular tube 5.Slide block 4 outward flange is just in time close on the inwall of casing 3, and between casing 3 and slide block 4, be provided with one can the flexible pull back spring 8 of horizontal direction, one end of pull back spring 8 is connected on casing 3, another end is connected on slide block 4, and wherein pull back spring 8 and rectangular tube 5 lay respectively at the left and right sides of slide block 4.The side that casing 3 is positioned at slide block 4 is provided with the seam block 9 being close to casing 3 front and rear wall, and wherein seam block 9 and pull back spring 8 are positioned at the same side of slide block 4, and seam block 9 is positioned at the below of pull back spring 8, is returned to position accurately to control pull back spring 8.
Vehicle chassis when in use, is positioned on vehicle frame 3, then in rectangular tube 5, places trailer rope by Telescoping trailers mechanism of the present invention, and be fixed on by unhook latch 7 in rectangular tube 5, now trailer rope is sheathed on unhook latch 7.Pull trailer rope; slide block 4 moves towards the direction of front bumper; unhook latch 7 is made to extend beyond the outside of front bumper; now trailer rope is positioned at the outside of front bumper completely; like this in the process of trailer; trailer rope all can not collide with front bumper and rub, and well plays effect of protection front bumper.Simultaneously owing to casing 3 being positioned at the existence of the sidewall of perforate upper and lower, pull back spring 8 can be avoided to be drawn out outside casing 3.After finishing using, unclamp trailer rope, due to the restoring force of pull back spring 8, pull back spring 8 is with movable slider 4 to get back to initial position, simultaneously due to the existence of seam block 9, makes pull back spring 8 be returned to original position accurately.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, can also make some improvement under the premise without departing from the principles of the invention, and these improvement also should be considered as protection scope of the present invention.
