Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming and provides that a kind of reliable working performance, manufacturing cost are little, installation and maintenance are used for the anti-brake gear that knocks into the back of dolly easily.

Formation of the present utility model: by overcoat, strut, spring perch, spring, motor, cam, structure is hung in locking, hang the structure seat, cushion block, the fixed block of band fixed orifice, damper spring, rubber pad and toughness band are formed, overcoat is a square tube shape, fixed orifice and return backguy support A with holes is arranged on the right-hand member trailing flank of square tube, mounting spring seat in the overcoat of the left side of fixed orifice, the fixed block that the band fixed orifice is arranged on the left end upper side of overcoat, on the leading flank of overcoat, install and hang the structure seat, suit locking hook on hook base, outside the left side of hook base, put hanging hole A, stay bearing plate is installed in front lower place at overcoat, motor is installed on stay bearing plate, in the rotating shaft of motor cam is installed, cam cooperates with the locking hook that colludes on hanging hole A; In the square hole of overcoat, strut is installed, mounting spring between strut right-hand member and the spring perch, at the strut left end hanging hole B is arranged, hanging hole B is corresponding with the hanging hole A that puts outward, at the strut left end push pedal is installed, at the hinged brake shoes in the push pedal left side, upper end, the right side installs back bit line support B with holes and in the lower left of push pedal level rubber pad and toughness band is installed, and between brake shoes and push pedal damping spring is installed.

Return backguy support A with holes is the trailing flank rear portion that level is contained in overcoat, the aperture above-below direction, and return backguy support B with holes vertically is contained in the push pedal right side, and the aperture fore-and-aft direction is with corresponding before and after the return backguy support A with holes.

The utility model compared with prior art has tangible advantage and beneficial effect.Decided on a verdict as can be known by above technology, structure of the present utility model and principle are simple, reliable working performance, manufacturing cost is little, installation and maintenance are convenient, accident generation such as prevent that effectively rear-end collision, brake failure and trailing wheel from blowing out.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the birds-eye view of Fig. 1;

Fig. 3 is running condition figure of the present utility model.

Among the figure 1, overcoat, 2, strut, 3 fixed orifices, 4, spring perch, 5, cam, 6, locking hook, 7, hanging hole A, 8 return tape hole support A, 9, spring, 10, hanging hole B, 11, brake shoes, 12, the fixed block of band fixed orifice, 13, return backguy support B with holes, 14, damping spring, 15, rubber pad, 16, toughness band, 17, motor, 18, hook base, 19, stay bearing plate, 20, push pedal, 21, wheel.

The specific embodiment: below in conjunction with accompanying drawing and preferred embodiment, to being used for the anti-brake gear specific embodiment, structure, feature and the effect thereof of knocking into the back of dolly according to what the utility model proposes, describe in detail as after.

Referring to Fig. 1-3, the anti-brake gear that knocks into the back of dolly that is used for of the present utility model, by overcoat, strut, spring perch, spring, motor, cam, structure is hung in locking, hang the structure seat, cushion block, the fixed block of band fixed orifice, damper spring, rubber pad and toughness band are formed, overcoat 1 is a square tube shape, fixed orifice 3 and return backguy support A8 with holes is arranged on the right-hand member trailing flank of square tube, mounting spring seat 4 in the left side of fixed orifice overcoat 1, the fixed block 12 that the band fixed orifice is arranged on the left end upper side of overcoat 1, on the leading flank of overcoat 1, install and hang structure seat 18, suit locking hook 6 on hook base, outside the left side of hook base, put hanging hole A7, stay bearing plate 19 is installed in front lower place at overcoat 1, motor 17 is installed on stay bearing plate, cam 5 is installed in the rotating shaft of motor, cam cooperates with the locking hook 6 that colludes on hanging hole A7; Strut 2 is installed in the square hole of overcoat 1, mounting spring 9 between strut 2 right-hand members and the spring perch 4, at strut 2 left ends hanging hole B10 is arranged, hanging hole B10 is corresponding with the hanging hole A7 on the overcoat 1, at strut 2 left ends push pedal 20 is installed, at the hinged brake shoes 11 in the push pedal left side, upper end, the right side installs back bit line support B13 with holes and in the lower left of push pedal 20 level rubber pad 15 and toughness band 16 is installed, and damping spring 14 is installed between brake shoes 11 and push pedal 20.
