如专利公开号为CN220231331U的中国专利公开了一种钢棒材质量检测装置，该装置左右两组定位板之间通过串联杆连接在一起，能左、右调整位置，其支撑底板的底部对称设有四组橡胶支撑垫，放置在移动柜的顶部，稳定不晃动，移动柜的底部对称设有四组移动轮，能方便移动位置，移动柜的正面设有带暗拉手的左、右开拉门，用于存储一些日常维修工具和劳保防护用品；For example, a Chinese patent with a patent publication number of CN220231331U discloses a steel bar quality inspection device, in which two sets of positioning plates on the left and right sides of the device are connected together by a series rod, and the positions can be adjusted left and right. The bottom of the supporting bottom plate is symmetrically provided with four sets of rubber support pads, which are placed on the top of the mobile cabinet and are stable and do not shake. The bottom of the mobile cabinet is symmetrically provided with four sets of moving wheels, which can be easily moved. The front of the mobile cabinet is provided with left and right sliding doors with hidden handles, which are used to store some daily maintenance tools and labor protection supplies;

The slide is completely pushed by manpower when sliding along the track. When the steel rod is heavy, the slide is difficult to move and the labor intensity is high. Therefore, a steel bar quality detection device is designed to solve the above problems.
