Problems solved by technology

[0009] This method adopts the fault structure connection, disconnects the connecting part after reaching a certain torque, and achieves the effect of deep burial. This method does not solve the vibration tripping of the bolt when it vibrates, but only achieves that it cannot be opened by man-made tools in the later stage. , can not solve the defects of the existing technology; and it cannot be opened again during maintenance, which also brings trouble to the later maintenance to a certain extent

Embodiment Construction

[0037] Below, refer to the attached Figure 1 to Figure 3 As shown, a reusable non-return bolt includes: a bolt body 101, a nut, a limit block 105, a dust pad 104, a limit rod and a non-return unit 103a;

[0038] Further, the bolt shank 101 is provided with threads that match the nuts, and a vertical slot 102 is provided at the center line of the bolt shank 101 for loading the limit block 105;

[0039] As an example, the dust-proof pad 104 is a combination of three, four or more than four leather pads, arranged symmetrically and concentrically, and tightly fitted for dust-proof and waterproof; After being inserted and pulled out, the dust-proof pad 104 will protrude slightly upwards and close tightly due to the friction force, which has an excellent umbrella-shaped rainproof effect and will not generate water accumulation;

[0040] Further, the diameter of the limiting block 105 is slightly smaller than the slot hole 102, and the shape is the same as that of the slot hole 102...

Abstract

A reusable non-return bolt comprises a bolt rod body, a nut, a limiting block, a dust-proof pad, a limiting rod and a non-return unit. Threads matched with the nut are arranged around the bolt rod body, a vertical slotted hole is formed in the center line position of the bolt rod body and used for installing the limiting block, and the non-return unit comprises return springs, positioning rods andthrough holes formed in the side wall of the bolt rod body. Scientific structural design is adopted for the reusable non-return bolt, the deficiency of insecure fixation of a traditional bolt is overcome, the reusable non-return bolt can be applied to trains with high vibration frequency, aircrafts, steamers and other environments, and because of reusable ingenious structural design, the operability of overhauling and maintenance is greatly improved, and the post-maintenance cost and repeated replacement frequency of spare parts are reduced. The reusable non-return bolt has a certain burglaryprevention effect and has a certain effect of stopping destroy and stealing of criminal offenders.

Description

technical field [0001] The patent of the present invention relates to the technical field of bolt structures, in particular to a reusable non-return bolt and its usage method. Background technique [0002] In the process of modern industrial production, building construction and people's daily life, we usually need to use bolts as a part, and use bolt connection to fix two structures to facilitate production and life; but the movable connection of bolts will definitely The loosening of the nut, no matter how tight it is, may cause the bolt to trip due to vibration and use, resulting in production accidents or inconvenience in life; [0003] In order to achieve the effect of bolt fastening, the prior art adopts the following structures to overcome the deficiency of bolt tripping: [0004] ①A spring sheet structure is set under the nut: when the nut is tightened on the bolt, the pressure of the nut to return in the opposite direction is increased, so as to increase the fricti...
