Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole
Embodiment.Embodiment in based on this utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of this utility model protection.
Such as Fig. 1-Fig. 2, this utility model embodiment provides a kind of road and bridge bearing, including lower connecting plate 1 and cylinder 5,
1 upper surface corner of lower connecting plate is mounted on sleeve pipe 10, and 10 interior side of sleeve pipe is respectively connected with damping spring 2, and damping spring 2 is another
One end is socketed with motion bar 3, and motion bar 3 is hinged and is connected to pillar 9, by the cooperation of sleeve pipe 10 and 3 one end of motion bar, can be effective
Weaken the active force of road and bridge generation, reach the effect of damping.
Pillar 9 is provided with fixture block 91 away from one end of lower connecting plate 1, and 91 both sides middle part of fixture block is provided with hole clipping 911, circle
The draw-in groove 51 coordinated with fixture block 91 is provided with cylinder 5, and 51 inside both sides of draw-in groove are equipped with back-moving spring 511, back-moving spring 511 1
End is respectively connected with the projection 512 coordinated with hole clipping 911, it is achieved that detachable between pillar 9 and cylinder 5, facilitates bearing
Installation.
