The specific embodiment
In order further to understand structure of the present utility model, feature and purpose thereof, see also the detailed description of following relevant drawings and the specific embodiments of the present utility model:
As shown in Figure 1a, for preferably can be used as the block diagram of the folding trailer bar of triangle warning plate according to the utility model one.This trailer bar comprises first side lever 10, second side lever 20 and middle drawbar 30.Middle drawbar 30 two ends are by pin 303,305 pivotal joints, first side lever 10 and second side lever 20.First side lever 10 and second side lever, 20 outer ends are respectively equipped with car puller hook 105,205, and be provided with latching device at car puller hook 105,205 opening parts, this latching device can be to be provided with groove in car puller hook 105,205 bottoms, the spring leaf 104,204 that is embedded at groove, also can select other known structure for use, be used to seal the opening of car puller hook 105,205, prevent to break off relations in the trailer process.See also shown in Fig. 1 b, the 1c, first side lever 10, second side lever 20 are provided with groove 113,210, middle drawbar 30 two ends respective fixation rivets 304,306.Open when being used for trailer when the trailer bar, rivet 304,306 is stuck in the groove 113,210, can prevent that first side lever 10, second side lever 20 from turning back to middle drawbar 30 directions.
As shown in Figure 2, be the generalized section of Fig. 1.For preventing that second side lever 20 from moving up and down along pin 305, fixing by straight pin 206,209,206,209 with pin 305 for captiveing joint, and size is greater than the diameter of pin 305.In order to increase the pulling force of trailer bar, trailer bar inside is provided with rope 40, and an end of rope 40 passes the hole 110 on first side lever 10, and the other end passes the hole 208 on second side lever 20, and the two ends of rope are respectively by clamp 112,207 chuckings.See also Fig. 3, be the local enlarged diagram of Fig. 2, steel disc 106 welding are fixed on first side lever 10, round steel sheet 107 and 108 is positioned at 106 both sides, its external diameter is greater than the opening size of steel disc 106, and there is the straight pin 109 that passes circular hole 110 round steel sheet 108 back, prevents that round steel sheet 108 from coming off.
In conjunction with shown in Figure 1, first side lever 10 is connected to form by pin 103,303 by the parallel plate that two block gaps are provided with again, and this forms first accepting groove at interval.Middle drawbar 30 is connected to form by pin 303,305 by the parallel plate that two block gaps are provided with, and this forms second accepting groove at interval.The inboard of 30 liang of parallel plates of drawbar in the middle of two parallel plates of first side lever 10 are positioned at.See also Fig. 4 and shown in Figure 5, when the trailer bar did not use, around middle drawbar 30 during to 180 ° of its accepting groove pivoted, second side lever 20 was housed in second accepting groove with second side lever 20; Then with first side lever 10 around middle drawbar 30 during to 180 ° of its accepting groove pivoted, first side lever 10 is housed in second accepting groove, the accepting groove of first side lever 10 is accommodated second side lever 20 simultaneously.Trailer bar volume after folding is little, can reduce institute and take up space.
This trailer bar also can be used as triangle warning plate and uses except that can be used as general trailer bar use.Outside face at first side lever 10, second side lever 20 and middle drawbar 30 passes through fixedly reflex-reflective material 101,201,301 of rivet 102,202,302 respectively.In conjunction with shown in Figure 6, the block diagram when forming triangle warning plate for the trailer bar.When first side lever 10, second side lever 20 fold to middle drawbar 30 directions, the groove 203 on second side lever 20 is stuck on the pin 103, can form triangle warning plate.Preferably on cover one magnetic cover 111 on the pin 103, groove 203 is stuck on the magnetic cover 111, the magnetic of magnetic cover 111 can be reinforced the firmness of triangle warning plate.Consult Fig. 7 simultaneously, drawbar 30 bottoms in the middle of iron plate 312 is fixed by welding in are fixed with strut bar 307,308,309,310 by rivet 311 on the iron plate 312.During use, the strut bar 307,308,309,310 of middle drawbar 30 bottoms is opened, be used for the support triangle warning sign as support.During as temporary term stop on highway, triangle warning plate is placed on the distance at 50 to 100 meters at car rear, the reflected light that the reflex-reflective material 101,201,301 by triangle brand sends reaches the safety-conscious effect of back car of reminding.
Under creative ideas of the present utility model, those skilled in the art can make various changes and modifications to said structure, but all belongs to protection domain of the present utility model.The description of the foregoing description is exemplary and not restrictive, and protection domain of the present utility model is determined by claim.
