2results about How to "Guaranteed splicing accuracy" patented technology

The application belongs to the field of track assembly and relates to a positioning mechanism for assembly, which is used for positioning a plurality of products arranged in a straight line. The positioning mechanism comprises a bottom base plate, a locking piece and a correcting piece. The bottom base plate has a front surface and a back surface. The back surface is configured to be connected with the ground in a positioning mode, and the front surface is configured to support the splicing ends of two adjacent products. The positioning mechanism can quickly realize accurate positioning of the products through cooperation of the locking piece and the correcting piece, so that the positioning operation can be quickly realized when the products are spliced. In addition, the splicing accuracy of the two products can be ensured through the correcting piece. Once position deviation occurs after splicing, the correcting piece can be used for re-correction, and the efficiency is high and the maintenance difficulty is low.

This utility model belongs to the field of water-stop screw technology, and particularly relates to a multifunctional water-stop screw assembly, including a water-stop screw pre-embedded part and screw parts threadedly connected to both sides of the water-stop screw pre-embedded part. Water-stop plates are provided on the outside of both sets of screw parts, and positioning seats are installed at opposite ends of both sets of water-stop plates. Adjusting nuts are threadedly connected to the outside of both sets of screw parts. By installing two sets of screw parts threadedly connected to both sides of the water-stop screw pre-embedded part, the two sets of screw parts can be rotated to adjust the extension length of the screw parts, thereby facilitating the adjustment of the overall length of the assembly. The positions of the two sets of water-stop plates can also be quickly adjusted, allowing them to move to the seepage channel, block the seepage channel, and allow the positioning rings on the outside of the two sets of water-stop plates to quickly contact the inside of the module, thus accurately positioning the water-stop plates and the water-stop screw pre-embedded part, ensuring the splicing accuracy of the template.
