This utility model discloses a press-fit blind hole nut structure, belonging to the field of press-fit nut technology. It includes a first retainer and a second retainer, a nut component, and a fixing bolt. The fixing bolt is installed at the inner center of the nut component. The nut component includes a toothed sleeve and a nut sleeve. The toothed sleeve is fixedly installed on the upper outer surface of the nut sleeve. A toothed portion for riveting metal plates is provided at the center of the upper outer surface of the toothed sleeve. The toothed portion has an overall toothed ring structure. The fixing bolt and the toothed sleeve, as well as the fixing bolt and the nut sleeve, are all connected by threads. Several sets of teeth are distributed in a ring on the outer surface of the toothed portion, with one end of each tooth having a pointed shape. This provides a press-fit rotation limiting structure, preventing synchronous rotation of the nut during subsequent bolt installation after it is connected to the sheet metal material. This allows the nut and bolt to be tightened to the maximum extent, improving their performance.

The utility model relates to the technical field of protective screen device, disclose a kind of windbreak and sand fixation protective screen device for callerya plantation, including fixed frame, the left and right sides and below in fixed frame are all provided with limiting slot, below the limiting slot is fixedly connected with multiple first spring in, the first spring top is fixedly connected with telescopic plate, left and right sides limiting slot are all provided with protective screen frame, and protective screen frame is set in telescopic plate top, the upper side of the both sides of protective screen frame is all provided with insertion slot, the upper side of the both sides of fixed frame is all penetrated and fixedly connected with fixed cylinder, two the fixed cylinder adjacent side is all provided with telescopic slot. In the utility model, when the levering member of the both sides of fixed frame is pulled out, the insertion post can be pulled out from the insertion slot and retracted into the telescopic slot by the movement of pull rod, and the protective screen frame can be ejected from the limiting slot by the elastic force of the first spring, so that the protective screen frame can be easily disassembled and replaced.

The utility model relates to the technical field of data lines, in particular to a data line, which comprises a data line main body, the data line main body comprises a wire core used for data information transmission and a wear-resistant leather sheath sleeved outside the wire core and used for wear-resistant protection, two ends of the wire core are provided with switching end posts, and two sides of the switching end posts are provided with connecting assemblies. The outer wall of the wear-resistant leather sheath is sleeved with a winding assembly. According to the data line, by arranging the wear-resistant and corrosion-resistant wear-resistant leather sheath made of polyester or polyethylene, the protection cooperation of the wire core is increased, the overall protection time is prolonged, the damage influence on the wire core is reduced, the overall service life is further prolonged, under the cooperation of the connecting assembly, the connecting end columns are fixed through the cooperation of the fastening bolts, and the service life of the data line is prolonged. And the winding assembly is installed, so that winding and collection of the data line main body are facilitated, and the influence of winding and knotting on use is reduced.

The utility model belongs to the technical field of landscaping, and particularly relates to a tree body whitewashing device with a coating liquid collecting structure, which comprises a tree body whitewashing device main body and a barrier plate mounted on the tree body whitewashing device main body, and fixing buckles are symmetrically arranged on the surface of an arc-shaped spraying pipe of the tree body whitewashing device main body. Fixing blocks are symmetrically connected to the arc-shaped inner wall of the blocking plate, springs are arranged in the fixing blocks, one end of each spring is connected with a buckle, a sliding groove is formed in the bottom face of the blocking plate, a liquid collecting assembly is installed on the bottom face of the blocking plate through the sliding groove in a clamped mode, and the liquid collecting assembly comprises a liquid collecting box and a sliding clamp. And the sliding clamp is fixedly connected to the top surface of the liquid collecting box. According to the utility model, the liquid collecting component is arranged at the bottom of the barrier plate, so that the whitewash coating liquid blocked by the barrier plate can flow into the liquid collecting box along with the flow, is collected and then is recycled, and further, the waste of the whitewash coating liquid and the coating cost are reduced.
