The invention discloses a traffic signal lamp post with convenient height adjustment and collision prevention in the technical field of traffic signal lamp posts. The traffic signal lamp post comprises a mounting base, a connecting sleeve slidably sleeves the outer wall of a stand column, the other end of a buffer assembly is connected with the outer wall of the connecting sleeve, and four groupsof screws are arranged on the outer wall of the periphery of the stand column in an annular array manner. The opposite ends of the four sets of screws extend to an inner cavity of the stand column tobe connected with a mounting plate, a motor is started to drive a screw rod to rotate, the screw rod rotates to enable a lamp box mounting frame to ascend and descend under the limitation of a slidinggroove and an open groove, and maintenance personnel can conveniently mount and dismount a lamp box. When an anti-collision sleeve is impacted, two groups of elastic arches are compressed, the elastic force generated by the deformation of the elastic arches weakens part of impact force, the elastic arches are compressed to enable the two sets of movable blocks on the upper side and the lower sideto slide on the outer wall of a sliding rod, the impact force is decomposed into component force in the vertical direction, the movable blocks compress the springs in the sliding process, elastic force generated by the deformation of the springs further weakens the component force in the vertical direction, and the anti-collision effect is achieved.
本发明公开了交通信号灯灯杆技术领域的一种便于调节高度防撞的交通信号灯灯杆,包括安装座,所述立柱外壁滑动套接有连接套筒,所述缓冲组件的另一端与连接套筒外壁连接,所述立柱四周外壁环形阵列设置有四组螺丝,四组螺丝相对一端延伸至立柱内腔连接有安装板,电机启动将带动螺杆旋转,螺杆旋转使灯箱安装架在滑槽和开槽的限制下升降,方便维修人员对灯箱进行安装和拆卸,在防撞套筒受到撞击时,将两组弹性弓压缩,弹性弓形变产生的弹力削弱部分撞击力,且弹性弓压缩使上下同侧的两组活动块在滑杆外壁滑动,将撞击力分解为竖直方向的分力,而活动块在滑动时将弹簧压缩,弹簧形变产生的弹力进一步削弱竖直方向的分力,达到防撞效果。
