Abstract

The utility model relates to an automobile protecting device, in particular to a tail protecting device for medium-heavy type trucks. The utility model aims at providing the tail protecting device for medium-heavy type trucks, which can effectively protect vehicles in rear-end collisions, thus avoiding casualty of passengers in the vehicles in rear-end collisions. The technical scheme is as follows: the tail protecting device for medium-heavy type trucks comprises a vertical fixed plate and a vertical protecting plate, wherein the protecting plate the height of which corresponds to that of a bumper of a sedan car is parallelly arranged in front of the fixed plate; a plurality of springs the axes of which are parallel to one another are arranged between the fixed plate and the protecting plate for separating the two plates; and bolts penetrate through holes on the protecting plate, inner holes of the springs, a gasket and through holes on the fixed plate, are connected with groove-shaped nuts by threads, and then are fixed by cotter pins. A rubber plate is also laminated on the outer surface of the protecting plate.

Description

Medium and heavy lorry tailstock protective device

Technical field

The utility model relates to a kind of automobile protective device, particularly a kind of tailstock protective device of medium and heavy lorry.

Background technology

According to media report, because some medium and heavy lorry tailstock are not provided with the actv. protective device, the afterbody of indivedual lorries has been installed bumper frame, but the installation site is higher.Along with popularizing of private car, the disappearance of the effective protective device of medium and heavy lorry afterbody causes all can taking place every year a lot of small passenger cars and knocks into the back and pierce the lorry bottom, causes the serious accident accident of car crash.

Summary of the invention

The purpose of this utility model provides a kind of protective device that is used for medium and heavy lorry tail, can play a protective role to the vehicle that knocks into the back effectively, thereby avoid injures and deaths that the vehicle occupant person of knocking into the back is caused.

The technical scheme that the utility model adopted is: a kind of medium and heavy lorry tailstock protective device, the adapter plate and the guar plate that comprise vertical placement, be set in parallel in the front of adapter plate with the corresponding guar plate of small passenger car bumper height, between separate with the parallel spring of several horizontal axiss, bolt passes through hole on the guar plate, spring endoporus, packing ring, adapter plate through hole and is threaded with throttled nut, and fixes with spring cotter.

The outside face of guar plate also is covered with rubber plate.

The beneficial effects of the utility model are, because at installation one of the front of adapter plate and the corresponding guar plate of small passenger car front bumper height, the front that is provided with spring and guar plate between two plates also is covered with rubber plate, the buffer action of spring and rubber plate can alleviate the damage to the vehicle that knocks into the back greatly, the vehicle occupant person's that effectively avoided knocking into the back injures and deaths.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.

Fig. 1 is the front view of the medium and heavy lorry tailstock protective device that proposes of the utility model.

Fig. 2 is that the A-A of the medium and heavy lorry tailstock protective device that proposes of the utility model is to cutaway view.

The sequence number of marking is described as follows in the accompanying drawing:

1. rubber plate, 2. guar plate, 3. spring, 4. packing ring, 5. grooved nut, 6. spring cotter, 7. bolt, 8. adapter plate.

The specific embodiment

As shown in Figure 1 and Figure 2, a kind of medium and heavy lorry tailstock protective device, the vertical adapter plate of placing 8 is captiveed joint with the loading space upper spider, be arranged in parallel in the front of adapter plate 8 one with the corresponding guar plate 2 of small passenger car bumper height, between separate with the parallel spring 3 of several horizontal axiss, bolt 7 passes through hole on the guar plate 2, spring 3 endoporus, packing ring 4, adapter plate 8 through holes and is threaded with throttled nut 5, and fixing with spring cotter 6.

In order to alleviate the collision to the vehicle that knocks into the back, the outside face of guar plate 2 also is covered with rubber plate 1, can be bonded on the guar plate 2, also can be screwed.

In order to dodge ground obstacle, the bending that makes progress of the bottom of guar plate 2, and the angle α between the vertical surface is 45 °～60 ° changes, and adapter plate 8 can be processed into vertical waist shaped hole with the through hole that bolt 7 matches, and the power of obstacle effect on the inclined-plane can make guar plate 2 lift one section height.

For the setting height(from bottom) that makes guar plate 2 corresponding with the small passenger car bumper height, thereby the effective protection vehicle that knocks into the back, its bottom surface ground-surface height of distance should change between 38cm～45cm.The length of guar plate 2 is equal to or slightly less than the loading space width, and height changes between 20cm～25cm.

As lorry mainly is to travel on scraggly road surface, in order to prevent the scratching of guar plate 2 and obstacle, can change the correspondence position of mounting hole and frame mounting hole on the adapter plate 8, and bolt together lifts adapter plate 8 and guar plate 2 integral body again.

The quantity of spring 3 changes between 3～6.
