The invention discloses a vehicle speed measuring device. The device comprises a support base arranged on a vertical rod and a speed measuring instrument connected with the support base in a matched mode; the upper surface of the speed measuring instrument is fixedly connected with a fixing protruding block and a positioning protruding block; a first groove is formed in the right side face of thefixing protruding block; a power connection block is arranged on the upper surface of the fixing protruding block; second grooves are formed in the left side face and the right side face of the positioning protruding block; a fixing groove and a positioning groove are formed in the lower surface of the support base; blind grooves are formed in the left side wall and the right side wall of the positioning groove; telescopic blocks are connected with the interiors of the blind grooves in a sliding fit mode; the telescopic blocks are connected with the bottom faces of the blind grooves through reset springs; a power connection groove is formed in the top surface of the fixing groove; a sliding groove is formed in the right side wall of the fixing groove; and a rack is connected with the interior of the sliding groove in a sliding fit mode. Through the arrangement of the positioning protruding block, the fixing protruding block, the telescopic blocks and the rack, the preliminary installation of the vehicle speed measuring device can be rapidly completed, and then the rack is made to stably insert and tightly insert the fixing protruding block, so that the whole device is stably installed.

    本发明公开了一种车辆测速装置,包括设置在立杆上的支架座和与所述支架座配合连接的测速仪,所述测速仪的上表面固定连接有固定凸块和定位凸块,固定凸块的右侧面设置有凹槽一,固定凸块的上表面设置有接电块,定位凸块的左右侧面均设置有凹槽二,支架座的下表面设置有固定凹槽和定位凹槽,定位凹槽的左右侧壁上均设置有盲槽,盲槽中滑动配合连接有伸缩块,伸缩块与盲槽的底面通过复位弹簧连接,所述固定凹槽的顶面上设置有接电槽,固定凹槽的右侧壁上设置有滑槽,滑槽中滑动配合连接有齿条。通过定位凸块、固定凸块、伸缩块以及齿条的设置,本发明能够快速完成初步安装,然后使得齿条将固定凸块插稳插紧,整个装置就被稳固安装了。
