Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of new and effective point tongue anti-bouncing device, Including hook plate 1, installation foundation is provided for structure thereon, 1 right end of hook plate prolongs hook plate 1 integrally formed with hook housing 3 Exhibition provides molding basis to shelve 5 surely, and 3 upper end of hook housing provides installation foundation integrally formed with shelving 5 surely, for tongue 6, Surely 5 left sides of shelving are fixedly installed with tongue 6, carry out the primary structure of track switch deflecting and guiding, the inside of the hook housing 3 It is fixedly mounted between 6 lower end surface of table top and tongue and leads power frame 2, the active force that tongue 6 is subject to is oriented to framework 3, avoids shelving 5 surely Counterclockwise swinging occurs in stress；

The power of the leading frame 2 includes pedestal 21, and for the basic mounting structure for leading power frame 2,21 upper end of pedestal is fixedly mounted 22 lower end of damping spring carries out damping to the pressure being subject to, while realizing the release of fluctuation energy by self-characteristic, described to subtract It shakes 22 upper end of spring and the seat of honour 23 is fixedly mounted, jointing switch toe 6 realizes fixed support installation, 21 left end table top of the pedestal weldering Twisted seat 26 is connect, provides hinged basis, hinged 25 lower end of force-guided stem of the shaft of the twisted seat 26, by tongue left end for force-guided stem 25 Active force guide seats 21 then realize the guiding role of power, and 25 upper end of force-guided stem, which is slidably installed, determines slide 24, Gu Dingan County fills 6 lower surface left end of tongue, when damping spring 22 being facilitated to compress, the sliding of 25 stress of force-guided stem.

Specifically, 1 upper surface of hook plate is equipped with rail 7, rail-guided main structure is carried out, while limiting tongue 6 bounce, 7 right side upper end of the rail fitting, 6 upper end of tongue left side, realizes effective guiding role.

Specifically, one end of the fixed installation stiffness spring 10 in 1 left end of hook plate, passes through the spy of stiffness spring 10 Property, the absorption for swinging energy is carried out, while the release of energy is realized by spring, the other end of the stiffness spring 10 is solid Dingan County fills 9 right end of push bracket, facilitates and pushes framework 1, controls 6 position of tongue, is rotatablely installed idler wheel 8 at the 9 left end crotch of push bracket, Facilitate promotion.

Be the main structure of tongue 6 specifically, the tongue 6 includes rail body 61,61 upper end of rail body one at Type rail point 64, the primary structure being oriented to, installation of 61 lower end of rail body integrally formed with limit base 62, to tongue 6 It is limited, 61 right flank middle part of rail body is welded with screw rod 63, and across 5 spiral shell loading nuts 4 are shelved surely, installation is fixed.

Specifically, sharp 64 upper ends of the rail are circular shape, the rigid contact directly squeezed is reduced, facilitates and is unloaded Power.

Working principle: in use, after device is installed, when there is vehicle to cross, wheel squeezes the rail point 64 of tongue 6, Tongue is pressed down against, power is oriented to hook housing 3 by the force-guided stem 25 by leading power frame 2, while being made by damping spring 22 to downlink Damping absorption is firmly carried out, while hook housing 3 drives 1 clockwise direction of hook plate to be swung, stiffness spring 10 carries out accumulation of energy, simultaneously By the characteristic of damping spring 22 and stiffness spring 10, energy fluctuation release is carried out, effective energy release is realized, works as vehicle After crossing, a possibility that discharging by the energy of early period, reduce bounce.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
