Abstract
The invention discloses an elastic-adjustment tow hook. The elastic-adjustment tow hook comprises a fixing panel, a first hollow tube and a hook, wherein the first hollow tube is arranged below the fixing panel; a second hollow tube is concentrically arranged in the first hollow tube; the hook is arranged at the front end of the second hollow tube, a blocking plate is arranged at the tail end of the first hollow tube, a spring connected with the tail end of the second hollow tube is arranged on the blocking plate, a bolt through hole is formed in the front part of the side wall of the first hollow tube, and one thread hole is formed in each of the front part and the rear part of the second hollow tube. With the adoption of the scheme of the elastic-adjustment tow hook, the hook can stretch and retract to change the overall length through cooperation of the first hollow tube and the second hollow tube, the driving safety of a vehicle is improved, and mounting and adjusting of a trailer are facilitated.
Description
Technical field
The present invention relates to automobile tow hook field, particularly relate to a kind of flexible adjustment car puller hook.
Background technology
Along with the continuous maturation of the flourish of China's economy and Trend of Auto Manufacturing Technologies, output and the sales volume of automobile rise year by year.Ripe production technology makes the cost of automobile and price be minimized, and therefore increasing entity and individual have purchased automobile, particularly Car ownership and obtained great lifting, and the prosperity of automobile industry has driven the development of peripheral vehicle product.
Major part vehicle all can arrange Trailer equipment at afterbody, other vehicles or conveying arrangement is dragged to facilitate, but the length of Trailer equipment is unadjustable, in order to the convenience of erection & lift, Trailer equipment is often given prominence at vehicle tail, there is no elasticity, when knocking into the back, the hazard ratio that Trailer equipment causes front vehicle is comparatively large, because Trailer equipment cannot shrink, increase the length of car load, length adjustment inconvenience.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of flexible adjustment car puller hook, can regulate the length of car puller hook entirety, improves the stability of convenience and the device regulated.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of flexible adjustment car puller hook, comprise: fixed flat planar, first hollow tubular and hook, described first hollow tubular arranges the below of fixed flat planar, described first hollow inner concentric tube is provided with the second hollow tubular, described hook is arranged on the front end of the second hollow tubular, the end of described first hollow tubular is provided with one piece of plugging plate, described plugging plate is provided with a spring be connected with the end of the second hollow tubular, the front portion of described first side wall of hollow pipe is provided with a bolt hole, the front and rear of described second hollow tubular is respectively arranged with a tapped bore.
In a preferred embodiment of the present invention, described first hollow tubular and the second hollow tubular are respectively square hollow tubular.
In a preferred embodiment of the present invention, described first hollow tubular is connected and fixed with adopting the mode of welding between fixed flat planar.
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, in described bolt hole, be provided with the bolt corresponding with tapped bore.
The invention has the beneficial effects as follows: a kind of flexible adjustment car puller hook that the present invention points out, the cooperation of the first hollow tubular and the second hollow tubular, make to link up with and stretched and change overall length, when second hollow tubular is pressed into the first hollow tubular, closed by the corresponding threaded holes of bolt and the second hollow tubular front portion, decrease overall length, improve the driving safety of vehicle, extract bolt, second hollow tubular moves to front end under the action of the spring, closed by the corresponding threaded holes at bolt and the second hollow tubular rear portion, conveniently carry out the installation of trailer, easy to adjust.
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 a kind of flexible adjustment car puller hook one of the present invention preferred embodiment.
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 flexible adjustment car puller hook, comprise: fixed flat planar 1, first hollow tubular 2 and hook 4, described first hollow tubular 2 arranges the below of fixed flat planar 1, the second hollow tubular 3 is provided with one heart in described first hollow tubular 2, described hook 4 is arranged on the front end of the second hollow tubular 3, the cooperation of the first hollow tubular 2 and the second hollow tubular 3, hook 4 is stretched and changes overall length, improve convenience and the safety of use, described first hollow tubular 2 and the second hollow tubular 3 are respectively square hollow tubular, concentric setting, slide convenient, stability is high.
The end of described first hollow tubular 2 is provided with one piece of plugging plate 6, described plugging plate 6 is provided with a spring 5 be connected with the end of the second hollow tubular 3, the front portion of described first hollow tubular 2 sidewall is provided with a bolt hole 21, the front and rear of described second hollow tubular 3 is respectively arranged with a tapped bore 31, is provided with the bolt corresponding with tapped bore 31 in described bolt hole 21.
When not needing trailer and the second hollow tubular 3 is pressed into the first hollow tubular 2, closed by the corresponding threaded holes of bolt and the second hollow tubular 3 front portion, decrease overall length, improve the driving safety of vehicle.During trailer, extract bolt, the second hollow tubular 3 moves to front end under the action of the spring, is matched, conveniently carry out the installation of trailer by the tapped bore 31 of bolt with the second hollow tubular 3 rear portion, easy to adjust.
Described first hollow tubular 2 is connected and fixed with adopting the mode of welding between fixed flat planar 1, and sound construction, durability is good.
