Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1, the present invention includes the fixation kit 3 of reel assembly 1, galvanized plate 2 and for being rotationally connected in galvanized plate 2 and loading space (not shown) front end.
As shown in Figure 2, reel assembly 1 comprises the spool 11 of a tubulose, plugs a cylinder 12 at the two ends of spool 11 respectively.All be connected by a volute spiral spring 13 between the outer wall of each cylinder 12 and the inwall of spool 11.The outer wall of spool 11 is fastenedly connected the side of a bolt 14, be fastenedly connected with the side of galvanized plate 2 after the some circles of opposite side winding reel 11 of batching 14, the opposite side of galvanized plate 2 is connected and fixed assembly 3.
In above-described embodiment, as shown in Fig. 1, Fig. 3, Fig. 4, galvanized plate 2 and the connection side of fixation kit 3 are provided with an elongated hole (not shown).Fixation kit 3 comprises anchor shaft 31, support 32 and a spring bracket 33.Anchor shaft 31 is located in the hole of galvanized plate 2.The front end of support 32 is plugged in the upper end of anchor shaft 31, and rear end and the loading space front end of support 32 are fastenedly connected.Spring bracket 33 comprises a bearing 331 and and is located in L-shaped bayonet lock 332 on two support arms of bearing 331.Bearing 331 and loading space front end are fastenedly connected, and bayonet lock 332 have been wholely set a bearing pin 333, are wholely set the connecting rod 334 that two are spaced and parallel layout between two support arms of bearing 331.At a sheathed spring 335 on the bayonet lock 332 between a support arm and bearing pin 333 of bearing 331.The top of bayonet lock 332 is plugged in the lower end of anchor shaft 31, by rotating the lower end of bayonet lock 332 to bearing pin 333 position parallel with two connecting rods 334, pulls bayonet lock 332 to drive bearing pin 333 Compress Spring 335 can realize the dismounting of anchor shaft 31.
In above-described embodiment, the width of galvanized plate 2 is less than 1.05m, and in the present embodiment, the width of galvanized plate 2 is 1m.
In above-described embodiment, batching 14 is waterproof, fire-retardant, anti-aging, corrosion prevention, polyvinylchloride (PVC) coated fabric that tensile strength is high.The cloth cover of batching 14 is groove type, and retractility is good and can save material.
In above-described embodiment, volute spiral spring 13 is prepared with spring steel.
As shown in Figure 1, during use, both sides between operator's compartment and loading space are fastenedly connected side deflecting plate (not shown) respectively, each cylinder 12 of the present invention is all fastenedly connected on the deflecting plate of every side by a support 4, upper and lowerly on the deflecting plate of every side be arranged at intervals with two guide grooves 5, the upper/lower terminal of batching 14 and/or galvanized plate 2 is stuck in a guide groove 5, can play the effect of guide-localization to galvanized plate 2.Under the effect of two volute spiral springs, batching is all subject to a pulling force and exceptionally straight all the time.When truck normally travels, galvanized plate 2 is stuck in guide groove 5 all the time, and when truck occurs to turn, batching 14 launches gradually, and galvanized plate 2 is away from guide groove 5, and when becoming a full member, batching 14 bounces back, and galvanized plate 2 is stuck in guide groove 5 again.Batching 14 and galvanized plate 2 can not produce with truck miscellaneous part and interfere in the process, effectively can reduce air resistance and reach the effect of saving oil consumption.
The various embodiments described above are only for illustration of the present invention, and wherein the structure, connection mode etc. of each parts all can change to some extent, and every equivalents of carrying out on the basis of technical solution of the present invention and improvement, all should not get rid of outside protection scope of the present invention.
