Problems solved by technology

In actual operation, in order to prevent the bolt rod and the nut from rotating synchronously in one direction, two wrench must be used to clamp the nut and the nut on two opposite working surfaces at the same time, but this method uses two wrench The effective way of "mutual protection" on two different working surfaces is often impossible due to various objective factors
For example, in the process of tightening a group of bolts, the bolt rod and the nut "rotate together", and the working surface where the nut is located is na

Embodiment Construction

[0031] Below in conjunction with accompanying drawing and specific embodiment, the present invention is described further: figure 1 It is a schematic diagram of a recessed dark nut of a larger diameter bolt. As shown in the figure, the bolt shaft 3 passes through the light hole 13 on the fastened part A8 and the fastened part B9 to thread the nut 5, and the head nut 4 It is inconvenient to use the live wrench 6 in the narrow working face of the fastener B9, so the inner hexagonal wrench 7 has to be used to block and turn the recessed dark nut 2 on the bolt tail end face 1. The recessed dark nut 2 is a recess on the bolt tail end face 1, and the recessed dark nut 2 is a recess in the diameter of the bolt shank 3, and the recessed dark nut 2 does not hinder the use of the screw thread on the bolt shank 3. The recessed recessed nut 2 adopts the recessed hexagonal groove form on the bolts with a diameter of 8mm or more and matches the inner hexagonal wrench 7. The purpose and func...

Abstract

The screw bolt with nuts in the two end include screw bolt end plane, head nut, inward concave hidden nut, screw bolt, nut, spanner, inner hexagon spanner and Philips driver. The screw bolt has two nuts in its two ends, and its tail end has inward concave hidden nut without affecting the use of the thread on the screw bolt. The inward concave hidden nut may be in the shape of inward concave hexagonal slot or crossed slot for matching the inner hexagon spanner and the Philips driver separately. The present invention makes it possible to complete the screw-in and screw-out job in one work plane only.

Description

technical field [0001] The invention relates to a fastener, in particular to a bolt with nuts at both ends. Background technique [0002] As we all know, a bolt only has a nut at the head end, and the diameter of the nut is larger than the diameter of the bolt shaft. In addition to squeezing the fastened part and fixing the position of the bolt from one side, the more important function of the nut is to The forced rotation of the wrench tool drives the bolts to be fastened or disassembled. Theoretically speaking, on the premise that the position of the nut does not move, only turning the nut can achieve the purpose of fastening or disassembling a group of bolts; To complete the task of fastening or dismantling a set of bolts. In actual operation, in order to prevent the bolt rod and the nut from rotating synchronously in one direction, two wrenches must be used to hold the nut and the nut on two opposite working surfaces at the same time. An effective way of "mutual prote...
