Abstract
The invention discloses a bidirectional adjustment tow hook which comprises a fixed flat plate, a hollow lifting pipe and a hook. A hollow telescopic pipe is concentrically arranged in the hollow lifting pipe, and the hook is arranged at the front end of the hollow telescopic pipe. A first hydraulic damping rod pointing to the hollow telescopic pipe is arranged at the rear end of the hollow lifting pipe, and the end of a telescopic rod of the first hydraulic damping rod is connected with the rear end of the hollow telescopic pipe. Two guide rods pointing to the hollow lifting pipe are arranged at the bottom of the fixed flat plate, and two guide sleeves corresponding to the guide rods respectively are arranged at the top of the hollow lifting pipe. The fixed flat plate is connected with the hollow lifting pipe through a second hydraulic damping rod. In this way, according to the bidirectional adjustment tow hook, the hook is adjusted in the height direction and the length direction, use is convenient, and the application range is wide.
Description
Technical field

Major part vehicle all can arrange Trailer equipment at afterbody, other vehicles or conveying arrangement is dragged to facilitate, but Trailer equipment is generally fixed on under-vehicle, its length and be highly all difficult to regulate, bad adaptability, cannot meet the operating needs of Some vehicles, the structure of vehicle is different, and common car puller hook reduces practicality.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of car puller hook of bidirectional modulation, can regulate height and length, improves Applicable scope.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the car puller hook providing a kind of bidirectional modulation, comprise: fixed flat planar, hollow fall way and hook, described hollow fall way be arranged in parallel the below of fixed flat planar, described hollow lifting inner concentric tube is provided with a hollow telescopic pipe, described hook is arranged on the front end of hollow telescopic pipe, the rear end of described hollow fall way is provided with the first hydraulic damping bar pointing to hollow telescopic pipe, the expansion link end of described first hydraulic damping bar is connected with the rear end of hollow telescopic pipe, the pilot bar that two are pointed to hollow fall way is provided with bottom described fixed flat planar, the top of described hollow fall way is provided with two orienting sleeves corresponding with pilot bar respectively, be provided with the second hydraulic damping bar between described fixed flat planar with hollow fall way to be connected.
In a preferred embodiment of the present invention, described hollow fall way and hollow telescopic pipe are respectively square hollow tubular.
In a preferred embodiment of the present invention, the bottom of described pilot bar is arranged in orienting sleeve.
In a preferred embodiment of the present invention, the opening part of described hook is provided with a spring anti-dropping pressing plate.
In a preferred embodiment of the present invention, described first hydraulic damping bar and the second hydraulic damping bar are respectively arranged with lockup switch.
The invention has the beneficial effects as follows: the car puller hook of a kind of bidirectional modulation that the present invention points out, the height of hollow fall way can be undertaken regulating and fixing by the second hydraulic damping bar, the length that hollow telescopic pipe stretches out in hollow fall way can be undertaken regulating and fixing by the first hydraulic damping bar, achieve the adjustment on hook height and length direction, easy to use, applied widely.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of car puller hook one preferred embodiment of a kind of bidirectional modulation of the present invention.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of car puller hook of bidirectional modulation, comprise: fixed flat planar 1, hollow fall way 2 and hook 4, described hollow fall way 2 be arranged in parallel the below of fixed flat planar 1, a hollow telescopic pipe 3 is provided with one heart in described hollow fall way 2, described hook 4 is arranged on the front end of hollow telescopic pipe 3, and hook 4 carries out upper and lower change in location with hollow telescopic pipe 3.
The rear end of described hollow fall way 2 is provided with the first hydraulic damping bar 5 pointing to hollow telescopic pipe 3, expansion link 51 end of described first hydraulic damping bar 5 is connected with the rear end of hollow telescopic pipe 3, the side-to-side movement with the flexible of expansion link 51 of hollow telescopic pipe 3, changes the displacement on hook 4 length direction.
The pilot bar 8 that two are pointed to hollow fall way 2 is provided with bottom described fixed flat planar 1, the top of described hollow fall way 2 is provided with two orienting sleeves 7 corresponding with pilot bar 8 respectively, is provided with the second hydraulic damping bar 6 and is connected between described fixed flat planar 1 with hollow fall way 2.Utilize the second hydraulic damping bar 6, change the position of hollow telescopic pipe about 3, thus change the displacement in hook 4 short transverse.
Described hollow fall way 2 and hollow telescopic pipe 3 are respectively square hollow tubular, and concentricity can ensure, structural integrity is good.
The bottom of described pilot bar 8 is separately positioned in orienting sleeve 7.The cooperation of pilot bar 8 and orienting sleeve 7, improves the stability that hollow telescopic pipe 3 moves up and down, and improves resistance to tension, sound construction, the good stability in trailer process.
The opening part of described hook 4 is provided with a spring anti-dropping pressing plate 41, avoids trailer rope in trailer process to come off from the opening part of hook 4, improves trailer safety.
Described first hydraulic damping bar 5 and the second hydraulic damping bar 6 are respectively arranged with lockup switch 9.Link up with after 4 length and short transverse have adjusted, locked by lockup switch 9, avoid changing in trailer process.
In sum, the car puller hook of a kind of bidirectional modulation that the present invention points out, hook 4 can move at height and length direction, improves comformability, is applicable to being arranged on multiple vehicle bottom and carries out trailer operation, simple to operate, easy to use.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
