Abstract
The utility model discloses an anti-drop bolt, which comprises a screw rod and a nut arranged on the screw rod, wherein the tail end of the screw rod is provided with a T-shaped head, the front end of the screw rod is provided with a first thread part and a second thread part, the thread directions of the first thread part and the second thread part are the same, and the screw rod between the first thread part and the second thread part is a non-threaded cylindrical buffer part.
Description
Technical Field
The utility model belongs to the field of hardware tools, and particularly relates to an anti-drop bolt.
Background
At present, scaffolds used in the building construction process are all connected in a buckling mode, and the applicant develops and improves 2022 and obtains patent rights aiming at the problems in the prior art, and the patent number is 2022206522310, and the problem that nuts are lost due to excessive rotation of electric tools in the disassembly process and are difficult to disassemble due to the fact that the nuts are not rotated in place when the electric tools are rotated excessively due to the fact that the two ends of the screws are provided with threads with opposite directions; however, in the actual manufacturing process, the applicant has found that to realize the arrangement of threads at two opposite ends of the nut, the production process must be increased, so that the difficulty of the production process is relatively high, the production efficiency is relatively high, the mass production and manufacturing are difficult to realize, the production cost is increased, and the effect of saving materials and reducing loss in the initial stage is not achieved.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art and provides an anti-drop bolt.
In order to solve the technical problems, the utility model adopts the following technical scheme: the utility model provides an anticreep bolt, includes the screw rod and sets up the nut on the screw rod, the end of screw rod is equipped with T type head, the screw rod front end is equipped with first screw thread portion and second screw thread portion, be equipped with the cylindric joint portion of no silk between first screw thread portion and the T type head, the screw thread direction of first screw thread portion and second screw thread portion is the same, and the screw rod between first screw thread portion and the second screw thread portion is the cylindric buffer portion of no silk.
Further preferably, the diameters of the first thread part and the second thread part are the same, the diameters of the first thread part and the second thread part are larger than the diameters of the buffer parts, the first thread part and the second thread part of the nut can slide freely on the non-threaded cylindrical buffer parts after being screwed off, and the distance between the nut and the T-shaped head part is adjusted.
Further preferably, the nut is a flange nut, the flange nut can move between the first threaded portion, the second threaded portion and the buffer portion, the flange nut fixes the in-out position of the sleeve of the electric disassembling tool, and the distance of disassembling the electric disassembling tool in the using process can be controlled.
Further preferably, the thread direction of the first thread portion and the second thread portion is the same clockwise direction or the counterclockwise direction.
Further preferably, the front end of the screw is provided with a stop, for example, the stop may be a flange plate fixedly provided with the screw end, or a stop protrusion provided with the foremost threaded end
The utility model has the beneficial effects that: through the first screw thread portion of two sections screw threads and the cylindric buffering adjustment part design of second screw thread portion and no silk, can guarantee to rotate from the second screw thread portion and get into the cylindric buffering adjustment part of no silk at the dismantlement in-process nut, through flange nut, the telescopic business turn over position of control electric power extracting tool, the dynamics is dismantled in control that can be better to flange nut better hovers at buffering adjustment part, can effectually reduce this bolt manufacturing cost.
