Abstract
The invention relates to a full-trailer towing hook belonging to the field of full trailers. The full-trailer towing hook comprises a towing plate (1), a buffer spring (4) and a towing rod (5), wherein the towing plate (1) is fixedly connected to one end of the towing rod (5), the buffer spring (4) is sleeved on the towing rod (5), guide sleeves (2) are sleeved on the towing rod (5) at two ends of the buffer spring (4) and are arranged symmetrically left and right, each guide sleeve is arranged in a step manner and comprises a large-diameter section and a small-diameter section, the small-diameter section is positioned on the outer side and the large-diameter section is positioned on the inner side, a buffer frame (3) is sleeved between the small-diameter sections of the two guide sleeves (2), and the large-diameter sections of the two guide sleeves (2) are positioned in the buffer frame (3). The full-trailer towing hook can play a buffer role when a full trailer is started or braked, and only needs one spring, thus the production cost and the installation difficulty are reduced, and the structure size is reduced.
Description
Technical field
The present invention relates to a kind of independent trailer hauling hook, belong to the independent trailer technical field.
Background technology
At present, the hauling hook of common independent trailer is through baffle plate of welding on draw bar, with the draw bar separated into two parts, is set with two springs (referring to Fig. 1) on the two-part draw bar being divided into.When independent trailer starting and brake, can play the effect of buffering, but the hauling hook of this structure not only need be installed two springs, has improved cost, increased installation difficulty, and scantling of structure becomes big, the increase of car occupation space.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of independent trailer hauling hook is provided, it not only can play buffer action when independent trailer starting and brake, and only need use a spring, has reduced cost and installation difficulty, and scantling of structure has also diminished.
The objective of the invention is to realize like this: a kind of independent trailer hauling hook, it comprises towing plate, recoil spring and draw bar, said towing plate is fixedly connected on draw bar one end; Said recoil spring (4) is set on the draw bar, is set with orienting sleeve on the draw bar at said recoil spring two ends, and said two orienting sleeves are symmetrical set; Said orienting sleeve is arranged to stepped; It comprises an enlarged diameter section and a reduced diameter section, and said reduced diameter section is positioned at the outside, and enlarged diameter section is positioned at the inboard; Be set with the buffering frame between the reduced diameter section of said two orienting sleeves, the enlarged diameter section of said two orienting sleeves is positioned at the buffering frame.
Compared with prior art, the invention has the beneficial effects as follows:
A kind of independent trailer hauling hook of the present invention not only can play buffer action when independent trailer starting or brake, and hauling hook only need use a spring, has reduced productive costs and installation difficulty, and scantling of structure has also reduced simultaneously.

The specific embodiment
Referring to Fig. 2 ~ Fig. 4, the present invention relates to a kind of independent trailer hauling hook, it comprises towing plate 1, recoil spring 4 and draw bar 5; Said towing plate 1 welding is arranged at draw bar 5 one ends, and said recoil spring 4 is set on the draw bar 5, is set with orienting sleeve 2 on the draw bar 5 at said recoil spring 4 two ends; Said two orienting sleeves 2 are symmetrical set, and said orienting sleeve 2 is arranged to stepped, and it comprises an enlarged diameter section and a reduced diameter section; Said reduced diameter section is positioned at the outside; Enlarged diameter section is positioned at the inboard, is set with buffering frame 3 between the reduced diameter section of said two orienting sleeves 2, and the enlarged diameter section of said two orienting sleeves 2 is positioned at buffering frame 3.Said draw bar 5 other ends are provided with screw thread, are set with catch 6 on the said thread segment, and said catch 6 arranged outside fluted nuts 7 are fixed.
Said towing plate is connected with tractor truck through bearing pin, and said buffering frame is captiveed joint with the draw bar assembly, and said draw bar assembly is connected with trailer through bearing pin.When tractor truck is started to walk; The draw bar that is welded with towing plate can travel forward in the buffering frame with tractor truck; The catch of draw bar afterbody, promotion rear portion orienting sleeve travel forward synchronously; Travelling forward of rear portion orienting sleeve can make the recoil spring compression, thereby makes the trailer part because the impulsive force that instant start brings obtains buffering, and gentle start goes; When tractor truck brakes, promote the orienting sleeve compression recoil spring of front portion through the step of draw bar head, make the trailer part because the impulsive force that brings that brakes suddenly obtains buffering, steadily stop.
